Abstract

The utility model discloses a floor latch structure, it includes base plate, tongue -and -groove and tenon, the tongue -and -groove is including the sunken first concave part of catatoxy inboard side, to the sunken second concave part in base plate top, the second concave part outside is the protruding hook foot that is formed with downwards, the tenon including with the first convex part of first concave part matched with, with second concave part matched with second convex part, with hook foot matched with hook groove, open flutedly on the second convex part, the embedded elasticity strip that is equipped with of recess, the recess is extended to elasticity strip upper end and the shaping has convexly protruding. The utility model discloses make floor tenon structure when the installation can produce certain elastic deformation, the installation of being convenient for makes the floor have expend with heat and contract with cold self -control function.

Description

A kind of floor board lock catch structure

Technical field:

This utility model is related to wood floor structure technical field, particularly to a kind of floor board lock catch structure.

Background technology:

In prior art, floor cannot firmly connect, can only be temporarily firm by way of gluing, if from not as good as rule The glue of lattice, the aging characteristic expanded with heat and contract with cold along with floor of glue while not environmentally, necessarily lead to occur splitting between floor Seam, has a strong impact on floor quality.

Utility model content:

This utility model provides a kind of floor board lock catch structure, solves the problems, such as to affect floor quality in prior art.

Technology solution of the present utility model is as follows: a kind of floor board lock catch structure, and it includes substrate, described substrate side Side is provided with tongue-and-groove, and another relative side is formed the tenon being matched with tongue-and-groove, and described tongue-and-groove is included inside oriented substrate First recess of depression, the second recess to surface depression, are formed with hook foot, institute to lower process outside described second recess State tenon and include the second protuberance that the first protuberance being matched with the first recess matched with the second recess and match with hook foot The hook and slot closed, described second protuberance has groove, is embedded with elastic strip in described groove, described elastic strip upper end is extended recessed Groove and form arc-shaped convex.

The structure arranging groove on the second protuberance makes tenon structure can produce certain elastic deformation when mounted, has Tenon structural failure when effect prevents floor from installing,；Sound of sighing be embedded elastic strip in groove and end face that elastic strip is contacted with tongue-and-groove on Form arc-shaped convex, which increase the flexible contact between floor, prevent connecting structure for floor board from deviating from.

Preferably, described first recess includes the horizontal bottom being sequentially connected, vertical side and sloped top face.

Preferably, described second recess includes the first inclined-plane being connected with sloped top face, described first inclined-plane connects There are horizontal top surface and the second inclined-plane.

Preferably, described hook outside of foot forms smooth arc-shaped surface.So make substrate easy for installation, will not damage tongue-and-groove and Tenon structure.

Preferably, the upper surface of described second protuberance is arc surface.So make substrate easy for installation, tongue-and-groove will not be damaged With tenon structure.

The beneficial effects of the utility model are: tenon structure produces certain elasticity change when mounted to enable floor Shape, is easily installed, and more makes connecting structure for floor board leave enough spaces, makes floor have the self-regulating function that expands with heat and contract with cold.

Brief description:

Fig. 1 is structural representation of the present utility model.

In figure: 1, substrate；2nd, tongue-and-groove；3rd, tenon；4th, the first recess；5th, the second recess；6th, hook foot；7th, the first protuberance；8、 Second protuberance；9th, hook and slot；10th, groove；11st, elastic strip；12nd, arc convex.

Specific embodiment:

In conjunction with accompanying drawing 1 to this utility model a kind of floor board lock catch structure, be described further.

A kind of floor board lock catch structure of the present utility model, it includes substrate 1, and substrate 1 one side is provided with tongue-and-groove 2, another The tenon 3 being matched with tongue-and-groove 2 is formed on relative side, tongue-and-groove 2 include oriented substrate 1 inner side depression the first recess 4, to Second recess 5 of substrate 1 top depression, is formed with hook foot 6 to lower process outside the second recess 5, tenon 3 includes recessed with first The hook and slot 9 that the second protuberance 8 that the first protuberance 7 that portion 4 matches is matched with the second recess 5 is matched with hook foot 6, second is convex Groove 10 is had on portion 8, in groove 10, is embedded with elastic strip 11, elastic strip 11 upper end extends groove and to form circular arc convex Play 12.

Further, the first recess 4 includes the horizontal bottom being sequentially connected, vertical side and sloped top face.

Further, the second recess 5 includes the first inclined-plane being connected with sloped top face, and the first inclined-plane is connected with level top Face and the second inclined-plane.

Further, form smooth arc-shaped surface outside hook foot 6.

Further, the upper surface of the second protuberance 8 is arc surface.

The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making creativeness The every other embodiment being obtained under the premise of work, all should belong to the scope of this utility model protection.
