Abstract

The present invention provides a buckle-jointed plate and a mounting and dismounting method thereof. The plate is formed with a tenon and a mortise on at least two opposite edges for mutually buckling and assembling plate units. By forming a stepped structure on an upper edge of each of the tenon and the mortise and achieving a mutual guidance with inclination angles of a first inclined guide surface, a second inclined guide surface, a third inclined guide surface and a fourth inclined guide surface, it is able to easily push the tenon into the mortise. Furthermore, by forming a locking structure, which has a cross-section in the form of an acute angle, on a lower edge of each of the tenon and the mortise, the plate units can be pushed and pressed on the same plane or can be inserted and rotated to form a buckle-jointed plate that can be easily locked and fastened and is not easily released after being locked. The plate unit is provided with a support block raised from an upper side of the tenon and a support trough formed on an upper side of the mortise. Therefore, by shaping the lower-side cross-section of the tenon and the mortise into an arc shape having a center at an outside surface of the support block or a highest point of a trough wall of the support trough, the assembled plate units can be turned over by taking the center as a support point, so that the lower edge of the arc shape slides relatively and abuts upon a locking block to cause a minor elastic deformation thereby allowing for easy withdrawal of the tenon after the turnover and thus disassembling and separating the plate units without causing damage to the buckle-jointing structure.

Description

Locking plate and its disassembly method

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 plate provided with a tenon and a tenon on the side of the plate so that the plate units can lock each other when splicing. .

The parquet floor has been used for a long time, and its assembly structure has also been applied to siding or similar boards. Let's take the floor as an example. The parquet floor is easy to assemble and allows the board units to be connected and combined, so it is widely used. Adopted by the industry, the relevant industry also spared no effort in research and improvement, hoping to design more practical products.

Among them, to avoid the basic use requirements of forming the top arch deformation or the gap between the joints between the panel units due to the phenomenon of wet expansion and shrinkage after the assembly of the parquet floor, in order to solve the aforementioned problems, currently the Chinese utility model patent such as CN02124731.5 has been adopted in Adhesive is provided between the tenon and the tongue and groove, or, for example, CN200520060450.6 and CN201020286029.8 Chinese utility model patents, by forming the tenon and the tongue and groove to form a lock-type plate with a self-locking function to achieve the plate unit Combined structural stability. However, the use of viscose to join the plate unit will make it difficult to disassemble the plate after assembly, and the disassembled plate unit is also difficult to reuse due to the presence of glue; the tenon and tenon-slot self-locking combination of the plate unit must be used when combining. One of the panel units can only be joined to the side of the other panel unit if it is tilted up. When the long side of the floor is combined and positioned and then the short side of the floor is combined, the short side of the floor can no longer be tilted, resulting in the floor. There is no lock structure between the short sides or can only be assembled by using the traditional flat buckle with no self-locking function, which reduces the locking effect between the plate units, and can not be tiled to form different patterns.

Another example is the series of Chinese invention patents such as "Floor composed of hard board units and methods of manufacturing such board units", such as CN97190692.0 approved by Unilin Management Private Company, which is mainly used to make the board units connect by tongues. After obliquely inserted into the plate groove, the tongues are used as fulcrum to rotate the plates to press them down and the planes are moved to each other. The mechanical locking device prevents them from disengaging, and then the short sides are combined and positioned before the short sides. When combining, you can still push to combine. However, in the aforementioned patents, when assembling and connecting sheet metal units in a plane-moving manner, they must increase the flat pushing force to force the protruding portion under the groove to deform elastically. Often, the other side must be knocked in order to make the corresponding short. Although the side assembly is combined with the positioning, although the locking effect between the plate units can be improved, it is inconvenient to operate and easily causes damage to the structure of the plate units when struck.

It is worth noting that during the assembly process of the parquet floor, there may also be the possibility that the assembled panel unit needs to be removed and replaced due to mismatches in color or other factors, or when the parquet floor is intended for secondary use It is also necessary to maintain the integrity of the corporate structure of the corporate floor. Therefore, in addition to the aforementioned technical problems in assembly of existing tongue and groove floors, the cross-section of the locking structure (such as the locking groove and the locking block) is generally at an acute angle during disassembly, and it is quite easy to cause mutual damage during disassembly.
