Description

Floor lock catch

Technical Field

The utility model relates to a floor hasp technical field, concretely relates to floor hasp.

Background

Most flooring systems in the flooring industry today, including laminate flooring, plastic flooring (LVT, PVC, SPC), part of engineered wood flooring, and part of engineered wood flooring, have locking systems to prevent removal or loosening of the flooring after installation. The floor boards are installed by snap-locking, the main advantage being that they are simple and quick, requiring substantially no special tools or adhesive material other than cutting. However, since the function of the locking device is to connect all the floor panels together, the strength of the locking connection is very important for practical use.

The floor lock catch is mainly a lock catch mechanism which is mainly arranged in the length edge direction of a floor, no matter what lock catch shape, a newly designed or old semicircular arc and the vertical direction of the ground are limited by a hidden groove and a tongue tenon, the horizontal movement is mainly limited by lock catches of two floors, the public tenon is provided with a convex shape, the female groove is provided with a concave shape similar to the shape of the public tenon, the convex shape of the public tenon and the concave shape of the female groove form a lock catch connected with the floor, and the floor is limited to move in the horizontal direction by friction force between the concave part and the convex part after being meshed with the convex part and the concave part, so that the requirement on the processing precision of the floor lock catch is higher, the floor lock catch is too tight to be installed, the floor can move freely and cannot play a limiting role. In addition, the locking of the tip, although having a certain restraining force, is very limited in effect.

The main problem of floor hasp at present is the long edge direction of floor not hard up or the dropout, if the hasp is not hard up or the dropout, also explain the connection failure/inefficacy between the floor, if the quantity is less, or not especially serious, available glue is restoreed, but if the area is great, the floor just needs whole changes, though floor itself can continue to use completely, the hasp inefficacy, including not hard up or the dropout, appears the gap of variation in size between board and the board, and the floor needs to be changed completely. This is not a small loss, either to the floor company, or to the customer of the use.

This is particularly the case with plastic flooring, mainly because plastic flooring is generally thinner than laminate flooring, the general thickness of laminate flooring is 12mm, while the thickness of plastic flooring is generally 3mm-8mm, because of the thinness of plastic flooring itself, the latch is smaller, and the connection between the latch and the flooring body is also weaker. The small lock catch can easily cause the false installation of the floor, namely, the lock catch between the floors looks as if the floor is buckled, but does not go into the floor completely, so that the floor can be quickly released when being installed and used. In addition, the lock catch and the floor body are connected in a single thin mode, so that the lock catch is easy to break in the installation and use processes, and the conditions of loosening and tripping can be generated.

Even if the floor is thicker, such as a reinforced floor, although the locking device can be larger and the connection of the floor body is better than that of a plastic floor, the locking device of the floor is not provided with a better limiting mechanism, and the locking device of the floor can be loosened or released due to the small change of the floor under the condition of environmental change. After the lock catches are loosened, the lock catches are released in the installation process, if the floor boards are repeatedly disassembled and assembled for several times, the friction force between the lock catches is reduced, and the problem of loosening or releasing of connection can also occur quickly after the floor boards are installed.

The main reason for this loosening or disengagement is the lack of a true locking device, although the so-called locking system, actually only has a buckle, but no lock, and the floor boards, after installation, are connected to each other to prevent the long sides from sliding or loosening in the horizontal direction, completely by the friction between the male and female buckles. If the long edge slides or loosens in the horizontal direction, the short edge of the end can drop in diameter or be damaged, the lock catch of the short edge of the end is lack of limitation, particularly the currently popular hasp is convenient to install, and the floor is not limited to move by any mechanism except that the public and female grooves are limited in the horizontal length direction. Thus, due to the movement of the floor, large gaps between the bottoms occur, resulting in the need to re-install a partial area or the entire floor. This is more of a problem with plastic flooring and is more likely to occur because the locking device is usually thinner and the locking force or control is less, and the locking device is more likely to loosen between the floor panels.

In a word, the horizontal direction of the lock catch floor is completely limited by the friction force between the male groove and the female groove, the convex-concave structures of the male falcon and the female falcon are straight, as shown in fig. 1 and fig. 2, because the convex-concave structures of the current lock catch male falcon 1 'and the female falcon 2' are straight, the longitudinal locking contact area is small, the friction force is limited, therefore, the limit effect of the existing design structure on the lock catch of the floor is limited, and even if the floor is locked, the problem of looseness of the floor is easy to occur.
