The soul of board furniture -three -in -one connection

The hotness of custom furniture is obvious to everyone. Today, the post -80s and post -90s have gradually become the mainstream of the times. Customized furniture just meets their needs for their personality. Let’s take a look at these personalized custom furniture ~

Behind this fiery, there are still many problems. Some large -scale custom -made furniture companies also have the quality problems of customer complaint products. Let’s talk about these pain points today.

It is said that tenon -mortar is the “soul” of solid wood furniture. The bumps of the tenon and the eyes are connected together. different

Forms have derived a ever -changing combination method, allowing the home to achieve the perfect unity of function and structure. In ancient my country, there was a long -term “no tenon, no mahogany”, which shows that tenon -and -mortise represents the precise, detailed and intelligent craftsmanship and the spirit of craftsmanship in traditional craftsmanship.

So, what is the soul of the most widely used board furniture now?

Everyone knows that plate furniture is made of composite materials, such as density boards, particle boards, etc. It has different solid wood furniture, and there is no tenon -and -mortise. The quality of the quality directly affects the quality of the entire furniture, including stability, service life, etc., which is also the soul of board furniture.

It is said that the details determine the success or failure, and the same is true of furniture. The furniture made of the quality of the quality of the quality, the quality of the connector is not available, maybe the furniture may be dispersed in two days. Some people often ask how expensive imported furniture is. In fact, the imported furniture is expensive at these fine branches.

Speaking of the connecting parts of board furniture, of course, the most used is the eccentric connector, also called the three -in -one connection. Three -in -one, as the name suggests, there are three parts: including eccentric wheels (eccentric heads), screws (connectors), and nuts (embedded parts). Depending on the material of the plate body, sometimes it does not need a nut.

The manufacturing of plate furniture connectors has gone through 30 years. Due to the low technology content of the manufacturing process and low threshold, the product quality level is uneven. How to judge the quality of a connector quality?

The most important thing about the three -in -one connection is the specifications and sizes of the eccentric wheel and the connector rod. The choice of embedded parts is more casual compared to the choice of embedded parts.

Potential wheel (eccentric head)

Among the three components of the three -in -one connection, the most important thing is the eccentric wheel, because it is the last step to achieve the connection effect, and it is also the key to whether the three -in -one connection can be disassembled again. As far as I know, many people like to use weight to judge the quality of bias. Of course, under the same size and shape specifications, the weight can be used as a reference indicator of a product quality. However, the weight is just the appearance of a certain attribute. The weight of the eccentric wheel is related to the quality of the raw material and the quality of the electroplated layer, but also related to the die casting process. If the product is at the same grade,

The overall weight can be relatively reflecting the quality of the product.

Look at two pictures first

Figure A

Figure B

Note: A and B size Specifies are the same: 15*12. A is zinc plating, B is nickel plating (the difference in the weight of the electroplating layer can be ignored) A weight is 3.6 grams; B weight 4.2 grams

From the naked eye, we can see that the difference between the eccentric head break in Figure A is obviously rough than B. (In fact, you can also pick up the wire tongs by yourself and break the eccentric head you bought to view. To better effect, you can use the magnifying glass to observe)

Mainly reflect two problems:

1. The quality of the raw materials: Figure B has a fine texture, high density, and no impurities. Figure A zinc alloy material is poor.

2, die casting process: Figure b die casting has a large strength, fine internal structure, small gap, no pores. Figure A is insufficient pressure, the internal structure of the product is loose, the molecular gap is large, and there are many pores.

Therefore, on the premise of the size and shape specifications, the weight is large and the quality will be better.

The impact of product attributes on quality

Screw (connection rod)

The quality of the connection rod is also very important. If the quality of the connecting rod of the three -in -one connecting connection is not closed, it will often cause furniture to be unstable after a period of use and cracks such as cracks at the link.

Good quality connection rods will be plated, but the general surface without electroplating is not smooth enough and easy to rust.

Narut (embedded parts)

Naruts, that is, the embedded parts we usually call, generally use the toughness and impact of imported nylon. It also depends on whether the internal and external teeth of the nut are sharp, because during installation, the external tooth link is the plate, and the inner teeth link is the screw. The inner teeth and screws are agglomerate by screws. The outer teeth are generally directly inserted into the plate. The sharpness of the internal and external teeth directly affects the stability of the connector.

In addition, it is still necessary to reiterate the specifications of the three -in -one connection, as shown in the figure below

In order to avoid competing with peers, some domestic connector manufacturers use unconventional size standards, such as: the connector uses non -integer size such as 35.5mm and 44.5mm. Although they greatly reduced the chances of replacing accessories for furniture manufacturers, they seriously harmed the interests of furniture factories. This has made great disadvantages to my country’s furniture industry and hardware accessories industry, and it is also one of the important reasons for the lack of national standards for furniture connectors in my country. As a furniture manufacturer, it should also resolutely resist this “corporate differentiation standard” product, so as not to cause unnecessary losses.
