Stretch snap close in a kind of floor
Technical field
The utility model relates to a kind of snap close, specifically refers to stretch snap close in a kind of floor.
Background technology
Fastening is mainly inserted by specific angle in traditional floor, although install more convenient, it also exists a lot of shortcoming.Such as, on irregular ground, traditional floor easily produces gap or is squeezed and floor epidermis reflex action is even ftractureed.When hot day, floor can expand, and mounted floor extrudes, and floor is heaved, damages.When winter, floor has certain contraction, at this moment there will be gap in the junction of every two floors, affects attractive in appearance.
Utility model content
The purpose of this utility model easily produces to solve after existing floor is installed the defect heaving or there will be in the junction of every two floors gap, provides a kind of and can expand according to floor after mounting, shrink the floor of adjustment connection degree of tightness automatically to stretch snap close.
This practical object is achieved through the following technical solutions: stretch snap close in a kind of floor, primarily of the male snap close and the female snap close composition that are arranged on plate body two ends, described public snap close is by the snap close head being arranged on plate body end, the first lock buckling groove be connected with this snap close head and the second lock buckling groove, and the first tenon be connected with the second lock buckling groove forms; Described female snap close is then by being arranged on plate body end and the 4th lock buckling groove matched with snap close head, be connected with the 4th lock buckling groove and the second tenon matched with the first lock buckling groove and the second lock buckling groove, and be connected with the second tenon and form with the V groove that the first tenon matches.
For guaranteeing result of use, the height of described snap close head is 1/3 of plate body width, and is also provided with trough with straight angle in the below of snap close head.
The utility model comparatively prior art is compared, and has the following advantages and beneficial effect:
(1) the utility model is provided with male snap close and female snap close, as long as when installing floor board the male snap close end of two floors and the mutual snap close of female snap close end, can save keel installation link when more traditional floor is installed, and it is easy for installation, saves and install manually.
(2) the utility model is after floor is installed, and between two floors, stayed gap, and female snap close is provided with the second tenon, the bottom of this second tenon has elasticity in the horizontal direction, and what well avoid that floor causes because of flexible heaves.
(3) tenon of the present utility model has elasticity floor is applicable on geothermal environment.
(4) the utility model demolition, installation are simple, avoid floor damage in demolition, installation process, thus realize repeatedly using of floor.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, male snap close 11 of the present utility model and female snap close 12 are the locked part of coupling mutually, and male snap close 11 and female snap close 12 are separately positioned on the two ends, left and right of plate body 1.As shown in Figure 1, this public snap close 11 by the snap close head 2 being arranged on plate body 1 end, the first lock buckling groove 4 be connected with this snap close head 2, the second lock buckling groove 5 be connected with the first lock buckling groove 4, and the first tenon 6 be connected with the second lock buckling groove 5 forms.
Described female snap close 12 by the 4th lock buckling groove 7 being arranged on plate body 1 end, the second tenon 9 be connected with the 4th lock buckling groove 7, and the V groove 10 be connected with the second tenon 9 forms.Wherein, the shape of the 4th lock buckling groove 7 and structure will match with snap close head 2, to guarantee, when connecting, to be buckled in the inside of the 4th lock buckling groove 7 in snap close head 2 energy.The structure of the second tenon 9 and shape will match with the first lock buckling groove 4 and the second lock buckling groove 5, during to guarantee to connect, are buckled in the groove of the first lock buckling groove 4 and the formation of the second lock buckling groove 5 lock in this second tenon 9 energy is complete.Correspondingly, the shape of the first tenon 6 and structure also will match with V groove 10.
For the fastening guaranteeing that male snap close 11 can be good with female snap close 12, therefore the height of this snap close head 2 will be 1/3 of plate body 1 width.Meanwhile, be also provided with trough with straight angle 3 in the below of snap close head 2, be then provided with a projection 8 matched with this trough with straight angle 3 in the below of the 4th lock buckling groove 7.When two boards body is fastened by male snap close 11 and female snap close 12, this projection 8 just in time matches with trough with straight angle 3 and combines.
As mentioned above, just well the utility model can be implemented.
