Floor board lock catch

Abstract

The invention relates to a floor board lock catch which comprises lock catch grooves, an oblique tenon and a lock catch head, wherein the lock catch is sequentially provided with a first lock catch groove, a second lock catch groove, the oblique tenon and the lock catch head from the close plate body to the tail end of a plate body, wherein the lock catch head protrudes outwards at the upper plane and the tail end of the oblique tenon; the first lock catch groove and the lock catch head coincides in dimension; the second lock catch groove and the distance from the bottom of the lock catch head to the middle part of the oblique tenon are corresponding in dimension; the oblique tenon is of a ladder shape; and lock catches at two sides are symmetrically with respect to a central axis. Through the optimization design, by utilizing the fitting between the lock catch head and the first lock catch groove, and the fitting of the lock catch head and the first lock catch groove, two floor boards can not move up and down; by utilizing the symmetrical ladder-shaped oblique tenon, the two floor boards can move left and right bidirectionally, the two floor boards generate a distance for dismounting, and the floor boards can be mounted when the distance disappears; the lock catches are symmetrical with respect to the central axis, and are simpler to manufacture; and the whole structure is simple, the mounting and manufacturing are convenient, and the aims of the lock catch can be obtained.
