Description

Pressing and snapping buckle plate and fastening method

The invention relates to a lock plate, which can be a splicing and assembling plate such as a floor or a wall plate, in particular, a bead and a groove are arranged on the side of the plate unit, so that the plate unit can lock each other when splicing. Plate. Background technique:

The tongue-and-groove floor has been used for quite a long time, and its assembly structure has also been applied to siding or similar panels. Today, the floor is taken as an example. The assembly of the tongue-and-groove floor is convenient and allows the plate units to be connected to each other, so it is widely consumed. The relevant industry has also spared no effort to carry out research and improvement, hoping to design a more practical product. According to the CN200610201430.5 Chinese invention patent application, it is an improved structure of the traditional tongue-and-groove floor. The assembly can be combined by the two plate units at the same horizontal plane; however, when the conventional tongue-and-groove floor is assembled, the plate unit is replaced by the plate expansion and contraction phenomenon. Deformation or gaps in the gap, the product will make people feel that the use of the effect is not significantly improved.

In order to solve this problem, a CN01214121.6 Chinese utility model patent case was designed, which can provide a self-locking function when the two plate units are bonded and combined, so that the two plate units can be firmly connected, but The structural design cannot be mass-produced by automated high-speed processing equipment, so there is still no related product on the market; another type of design is as

CN02124731.5 and CN201010580430.7 Chinese invention patent case, which is to apply adhesive on the joint 榫 and/or the connecting groove of the plate unit, so as to provide the effect that the plate units can be closely combined after being combined, but the use of the type The adhesive-bonded floor is bonded and fixed after laying. Unless the floor joint structure is damaged, it cannot be disassembled. This makes the floor unassembled and assembled separately. The use of adhesive will also cause environmental damage. Negative effects, not perfect design.

In another CN200520060450.6 and CN201020286029.8 Chinese utility model patent case, another different type of tongue-and-groove structure is proposed, which is designed to provide a combination of two plate units by a circular lock structure, which does not need to be used. Adhesives provide a combination of sheet units, which has better practicability. However, in this type of design, a sheet unit must be tilted to be inclined to be combined. To the side of the other sheet unit, this design has some troubles in the assembly of the sheet unit, because the tilting is inclined, that is, the assembly cannot be performed, so the short side of the floor can only be assembled by the conventional tongue and groove. The function of the lock can not be achieved, and as described in the Chinese utility model patent case of CN200520060450.6, the lower part of the main body short-side lock of the plate unit floor is cut flat by a part, so as to facilitate horizontal knocking, otherwise It is not possible to combine the short sides of the floor after the long side of the floor is combined.

There is also the CN97190692.0 series, which is approved by the Unicorn Management Private Company. The series of "10 panels (with panels with edge connectors), which was obtained in the United States by the company Unilin Beheer BV, "10 (^ panels with edge connectors)" The patent application has a total of more than 20 pieces, and its basic structure is the same. It has a connecting portion composed of a tongue and a groove, and an integral mechanical locking device is arranged on the connecting portion to prevent the two pieces from being connected to each other. The sheet unit is disengaged in a direction perpendicular to the relevant edge and parallel to the lower side of the interconnecting sheet unit, of course, characterized by a projection provided on the lower surface of the tongue, a groove provided on the lower convex portion of the groove And the elastically bendable lower projections are allowed to be joined to each other when they are relatively moved in a planar manner. This design allows the plate units to be connected to each other when they are inserted into the plate groove obliquely, and is connected to each other by the tongue-like tenon as a fulcrum, and the mechanical locking device is prevented from coming off. Open, because it is combined with the short side after the rotation, it can still be pushed and combined, which has its practicality. However, in this design, when assembling the connecting plate unit by means of plane displacement, it is necessary to increase the pushing force to force the lower convex portion of the groove to be elastically deformed, which requires considerable propulsion force, especially on the long side. The inclined assembly method has been adopted to allow the connecting part to be combined and positioned, and when the short side is to be combined, the short side can only be combined by the plane phase shifting manner, and the constructor often has to be tapped by the other side. The corresponding short-side assembly is combined with the positioning, which is inconvenient in operation, and it is also possible to damage the lower protruding portion of the tapped side tongue or groove when tapping, thereby affecting the subsequent Plate assembly work, obviously it still needs to be improved.

In addition, as seen from the lock-type floor currently seen on the market, although various manufacturers have adopted The structure of the raft and the groove is different, but the shape of the raft and the groove provided on the long side of the floor on the long side is not the same. According to the CN200520060450.6 Chinese utility model patent case, The main body of the lock on the long side is a circular arc lock structure. However, in this type of design, a plate unit must be tilted to be inclined to be joined to the side of another plate unit. This design is used when the plate unit is assembled. When the long side of the floor is slanted and joined to the positioning, and then the short side of the floor is combined, since the short side of the floor can not be tilted again, the assembly cannot be performed, so the short side of the floor can only be With different structures, the lower part of the main body of the short-side lock of the sheet unit floor in the patent is cut flat by a small part to facilitate horizontal knocking, otherwise the short side of the floor cannot be combined after the long side of the floor is combined. The combination of this means that the manufacturer must use more differently designed blade-shaped tools to perform the boring and groove processing of different structures. Of course, different tool-shaped tools are in the process of production and production. It will increase the inconvenience of tool installation and adjustment, which also lacks the design of the existing sheet metal and groove structure. Summary of the invention:
