Traditional furniture is connected by a wooden structure and does not require hardware accessories. However, with the development of furniture modernization and the increase of people's demand for exquisite life, hardware accessories have gradually become a very critical factor in measuring the overall quality of furniture. Whether you ask the woodworker to make furniture on-site, or customize or purchase finished furniture, the hardware of the furniture is a part that cannot be underestimated. Let's take a look at the purchase and maintenance methods of furniture hardware with the editor.
Part1: To understand more clearly the introduction of furniture hardware classification
When it comes to furniture hardware, everyone can more or less name the hardware used in furniture such as hinges, hinges, nails, etc. However, more detailed and in-depth knowledge about furniture hardware is not clear. Then, let's first understand the detailed classification of furniture hardware.
Classification of furniture hardware
Furniture hardware generally refers to the hardware components that need to be used in the production and use of furniture. There are many types of furniture hardware, and different types can be classified according to different classification standards.
1. Classified by material
Introduction to common materials of furniture hardware accessories
Copper
Is one of the most widely used materials, with good mechanical properties, good corrosion resistance and processing properties
Stainless steel
Durable, the more you use it, the brighter it gets. It has good strength, strong corrosion resistance and unchanged color
Zinc alloy
Its strength and anti-rust ability are poor, and the advantage is that it is easy to make parts with complex patterns
Aluminum or aluminum alloy
Ordinary aluminum alloy is soft and light, and the material strength is lower, but it is easy to process and shape
Plastic
Has the characteristics of easy processing, stable product size, good surface gloss, etc., easy to paint and color, and can also be subjected to secondary processing such as metal spraying, electroplating, welding, hot pressing and bonding
Ceramics
The materials with the best stiffness and hardness are mostly above 1500HV. High compressive strength, but low tensile strength, poor plasticity and toughness, not easy to oxidize, and good corrosion resistance to acids, alkalis and salts
The most common type of furniture hardware is classified by material, which basically includes single metal, alloy, plastic, ceramic, etc. Hardware of different materials has different performance and quality due to different characteristics of the material.
2, classified by purpose
Furniture hardware can be divided into solid wood furniture hardware, panel furniture hardware, cabinet hardware accessories, wardrobe hardware accessories, etc. according to different uses.
3. Classified according to role
Furniture hardware can be divided into functional furniture hardware, structural furniture hardware, and decorative furniture hardware. Among them, functional furniture hardware mainly includes three-in-one connectors, screws, etc., which play a connecting function, as well as slide rails, hinges, guide wheels, etc., which play a movement function; structural furniture hardware includes the metal structure of the glass coffee table, and the metal legs of the round table. Etc.; decorative furniture hardware includes aluminum edge banding, hardware pendants, hardware handles, etc.
Part2: common furniture hardware connection function hardware purchase
The connection function hardware generally refers to the parts that play the role of fastening and connecting between the board and the board in the furniture production process, mainly including: three-in-one connectors, screws, rivets, combination nuts, etc., and furniture Three-in-one connectors are the most commonly used connectors.
Three-in-one connector option
Three-in-one consists of three parts, which are eccentric head (also known as eccentric nut, eccentric wheel, eccentric piece, etc.), connecting rod (screw), and embedded nut (expansion bolt, commonly known as plastic pellets for plastic).
The advantages of three and one connector
Fasten the connection
Through the three-in-one connection of bolts, bolts and eccentric parts, the connection is tight and firm
Easy to disassemble
The three-in-one connection can be disassembled many times, which is also one of the advantages of the furniture made of it
Hidden
The three-in-one connector cannot be seen from the outer surface, which does not affect the appearance of the furniture
Environmental protection
Three-in-one connection reduces the use of adhesives and is more environmentally friendly
1, eccentric head
The eccentric head is also known as the eccentric connection matrix. Its working principle is due to the arc of the eccentric wheel deviating from the center of the circle. When the eccentric wheel is rotated, the connecting rod stuck in the arc will slowly approach the center of the eccentric wheel along the arc. Tighten the distance between the two plates to make the connection tight.
Generally there are zinc alloy and aluminum alloy. The most common one is made of zinc alloy through die-casting. Its common specification is φ15 (φ represents the diameter), which is a common specification for general furniture plates. Of course, some furniture drawers and other plates are thinner. Locally, the specifications of φ12 and φ10 are used. There are also some large-scale furniture. Due to the thickness of the plate and high load-bearing requirements, the specifications of φ35 and φ25 are used. In terms of current panel specifications in the furniture industry, φ15 is the most common and most used.
2, connecting rod
There are generally three materials: iron, zinc alloy, and iron + plastic. Among them, iron and zinc alloy are generally used in foreign countries. As the requirements of domestic furniture manufacturers are not so high, iron + plastic connecting rods are commonly used in China.
3, embedded nut
Zinc alloy, plastic, nylon are the most common. The three materials have their own strengths, and different materials can be selected according to different requirements.
Three and one connector installation
As for the three-in-one connector, many people don’t know how to install it. Therefore, here is also the general installation method of the three-in-one connector.
First install the embedded nut into the reserved hole; then install the screw on the embedded nut and tighten it; then align the hole of the other board with the screw and buckle it to one board, and then tighten the eccentric head. Tighten the screw.
Part3: Common furniture hardware, movable hardware hinge + slide rail purchase
Furniture movable function hardware is an important part to realize the movable function of furniture opening, closing and moving. Let's take a look at the two movable hardware parts, furniture hinges and slide rails.
Hinge purchase
Hinges are also called hinges. They mainly include ordinary hinges and spring hinges. They are the main components connecting the cabinet body and the door panel. In the daily use of furniture, hinges are the most tested. Therefore, the quality of the hinge directly affects the service life of the furniture, so be careful when purchasing.
Ordinary hinge purchase tips: The materials of ordinary hinges are mainly brass and stainless steel. The yellower the brass hinge is, the better, which indicates that the copper content is high. Poor hinges will cut corners, and are not up to the standard in terms of specifications and thickness. The thickness of a good hinge is about 3 mm, and the thickness of a poor hinge is relatively thin. Hinges with good sealing performance should be selected, and the flexibility and firmness can be felt by opening and closing and pulling several times when purchasing.
Spring hinge purchase tips: Spring hinges are divided into full cover, half cover and no cover, and are used for three different connection methods between the cabinet door and the cabinet. Choose to look for the brand, the spring leaf of the small brand is easy to age, fatigue, and cause the cabinet door to sag. Stainless steel and steel plate hinge wall panels are thin, but have good toughness and are not easy to break. The cast iron hinge siding is thick, but it is easy to break. Be careful not to lack the adjusting screw on the hinge, otherwise it will not be easy to match.
Slide rail purchase
Slide rails are usually grooved or curved guide rails for furniture doors, drawers or other moving parts, often equipped with ball bearings. Whether large and small doors and drawers in the furniture can be pushed and pulled freely and smoothly, as well as the load-bearing capacity, depends on the support of the slide rails.
Tips for choosing slide rails: When purchasing, first look at the material of the track. Plastic pulleys, steel balls, and wear-resistant nylon are the three most common pulley materials. Among them, wear-resistant nylon is the top grade, which is quiet and silent when sliding; Pull out the slide rail force, push and pull it by hand to see if it needs to be pulled out very hard; thirdly, see whether the slide rail is swaying, and the slide rails installed on the drawers should not sway too much.

Part4: Common furniture hardware, decorative hardware handle purchase
The handle is installed on the furniture, which not only saves manpower and facilitates home life, but also plays a good decorative role when matched properly. There are so many handles on the market that are similar in styles, but the prices are very different. The price of small handles can vary by several hundred, but the quality is hard to distinguish between good and bad. How to choose a handle that is satisfactory, high-quality, and relatively suitable for the price?
Look at the appearance of the handle
First check the color of the surface layer and protective film of the handle for damage and scratches. To judge the quality of the handle, first look at the surface treatment. A good sanding handle should be relatively dim in color and give a sense of stability; the parting line of semi-sand should be straight at the junction of bright light and sanding, if it is distorted The curved lines are obviously inferior; and a good shiny handle should reflect the color and luster like a mirror, bright and transparent, without any blemishes.
Try to handle the feel
Good handle, it should feel very comfortable to the touch. Therefore, when purchasing, you can try to feel it to see if the surface treatment is smooth, and it is not smooth to pull; the edge of a good handle should be smoothed, and there is no stubble or cut.
Listen to the sound of the handle
Some unscrupulous manufacturers in the market cut corners and filled the handle tube with cement or soldering iron or sand, giving people a heavy feeling to deceive consumers. To distinguish inferior handles, you can distinguish them from the sound. Tap the handle tube with a hard tool. The handle sound of a thick tube should be more crisp, while a thin tube is more dull.
Check the area around the screw hole
When choosing a handle, you need to pay attention to it. It is best to choose a handle with a larger area around the screw hole. Because the smaller the area around the screw hole of the handle, the more precise the handle hole punched on the board is required. Otherwise, a slight deviation will cause the handle hole to be exposed. Therefore, in order to prevent this from happening, you need to pay attention to check whether the area around the handle screw hole is too small when purchasing.
Choose the brand certification
Famous brand, of course the quality is high. Therefore, when buying, it is best to choose reputable brand products. In addition, in the current building materials market, most high-end door handles are imported. Imported handles usually have a sense of design, good texture, and relatively expensive. If you choose an imported handle, you can ask to see the import certification documents of the product to avoid the merchants from getting mixed up.
