Abstract

A lock-catch-type board and an assembly and disassembly method therefor. Tenons (10) and mortises (50) are formed at the at least two opposite side edges of the board correspondingly and are used for being mutually buckled and assembled to form board units (100). Step structures formed at the upper edges of the tenons (10) and the mortises (50), and oblique surface angles of a first oblique guide surface (16), a second oblique guide surface (17), a third oblique guide surface (56) and a fourth oblique guide surface (57) are mutually guided, so that the tenons (10) are more easily pressed and buckled into the mortises (50). Lock catch structures whose sections are acute angles are formed at the lower edges of the tenons (10) and the mortises (50), so that the lock-catch-type board fastened, buckled and not prone to being loosened in easy operations can be formed by performing push, press, or insertion and rotation actions among the board units (100) on the same plane. The board units (100) are provided with supporting blocks (20) on the upper sides of the tenons (10) in a protruding manner, and are provided with supporting grooves (60) in the upper sides of the mortises (50). Arc shapes taking the highest point of the outer side surfaces (21) of the supporting blocks (20) or groove walls (61) of the supporting grooves (60) as a circle center are formed in the sections of the lower edges of the tenons (10) and the mortises (50), so that the board units (100) can be flipped between the assembled board units (100) by using the circle center as a supporting point, the lower edges of the arc shapes relatively slip and press against a lock catch block (80) to achieve small scale elastic deformation, and can be easily drawn out of the tenons (10) after flipping, and the board units (100) are disassembled and separated when the lock catch structures are not damaged.

Description

Locking plate and its installation method

Technical field

The invention relates to a lock type plate, which can be a splicable plate such as a floor or a wall plate, in particular, a bead and a groove are arranged on the side of the plate to allow the plate unit to 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 used as an example to illustrate the ease of assembly of the tongue-and-groove floor and the combination of the plate units. Therefore, it is widely consumed. The employers have also spared no effort to carry out research and improvement, hoping to design more practical products.

Among them, in order to avoid the basic use requirement of forming the top arch deformation or the gap between the plate units due to the swelling and shrinking phenomenon after the assembly of the floor, in order to solve the above problems, the Chinese utility model patent such as CN02124731.5 has been passed. Adhesive is provided between the tenon and the gutter, or, for example, CN200520060450.6 and CN201020286029.8, the Chinese utility model patent is to realize the plate unit by forming the locking plate with the self-locking function by forming the tenon and the gutter. The stability of the combined structure. However, the use of viscose bonded sheet unit will result in the sheet being easily disassembled after assembly, and the disassembled sheet unit is also difficult to reuse due to the presence of glue; the use of the tongue and groove self-locking combination of the sheet unit must be combined One of the plate units is tilted to be joined to the side of the other plate unit, so that when the long side of the floor is combined and positioned, the short side of the floor is combined, and the short side of the floor cannot be tilted again, resulting in a floor. There is no lock structure between the short sides or can only be assembled by the traditional flat tongue with no self-locking function, which reduces the locking fastening effect between the plate units, and can not be laid to form a different pattern of parquet.

Another example is the CN97190692.0 series, such as CN97190692.0 approved by the privately-owned company, and the Chinese invention patent case, which is mainly used to make the plate units connected to each other. After being obliquely inserted into the groove of the plate, the plate is pressed and pressed by the tongue-like tenon as a fulcrum, and the plane is pressed to be connected to each other, and the mechanical locking device is prevented from being disengaged, so that the short side is combined and the short side is combined. When combined, it can still be pushed in combination. However, the aforementioned patents are assembled when the panel unit is assembled by means of plane mutual displacement. It is necessary to increase the pushing force to force the convex portion of the groove to be elastically deformed, and it is often necessary to knock the corresponding short side assembly to the positioning by tapping on the other side, although the locking between the plate units can be improved. The effect is that it is inconvenient to operate and is liable to cause damage to the structure of the sheet unit when struck.

It is worth noting that during the assembly process, there is also the possibility that the assembled plate unit needs to be removed and replaced due to wrong color mosaic or other factors, or when the floor is to be used twice. It is also necessary to maintain the structural integrity of the tongue and groove floor. Therefore, in addition to the technical problems in the assembly described above, the existing tongue-and-groove floor is also generally caused by the fact that the cross-section of the lock structure (for example, the lock groove and the lock block) is acute at the time of disassembly, and it is quite easy to cause disassembly. The acute angle structure of each other is damaged, and there is a need for improvement.
