The specific embodiment:
See also Fig. 1～Fig. 4, this specific embodiment of the utility model is as follows: comprise floor board block 1, one end of floor board block 1 is a groove 2, the other end with respect to the floor board block 1 of groove 2 has a tongue 3, key is that the soffit of tongue 3 has an arc-shaped convex 4, to the rear end, radius of curvature increases gradually from the front end of arc-shaped convex 4, and the lower wall upper surface of respective grooves 2 has the circular arc-shaped recess 5 suitable with above-mentioned arc-shaped convex 4; The soffit of tongue 3 is an arc-shaped convex 4, the lower wall of corresponding groove 2 has the circular arc-shaped recess 5 that matches and do not produce crimp and produce stress with above-mentioned arc-shaped convex 4, use when installing, the tongue of tool arc-shaped convex 4 rotates into and is connected to form a row floor in the groove 2 of tool circular arc-shaped recess 5, proceeds to the floor assembly unit of whole large tracts of land repeatedly and finishes.
The radius of curvature of above-mentioned arc-shaped convex 4 is to increase gradually continuously, or the radius of curvature of arc-shaped convex 4 is that segmentation increases gradually, arc-shaped convex 4 is made of the arc section of different curvature radius, the part that at first enters groove 2 of arc-shaped convex 4 is defined as leading section or leading portion circular arc 6, the root of arc-shaped convex 4 is defined as rear portion or back segment circular arc 7, the radius of curvature of the leading section of above-mentioned circular arc is less and along with arc-shaped convex 4 extends back gradually, the radius of curvature segmentation increases, its advantage that has is that leading section can not contact (as shown in Figure 4) when entering circular arc-shaped recess 5, along with rotating into gradually in the groove 2 of tongue 3, basically do not produce extruding between arc-shaped convex 4 and the circular arc-shaped recess 5, when particularly the back segment circular arc 7 of arc-shaped convex 4 is only in tongue 3 enters groove 2 fully, just match with circular arc-shaped recess 5; Arc-shaped convex 4 can not cause the lower wall distortion of groove 2 and the root of the lower wall that the generation distortion may cause and the junction of floor board block 1 fine crack to occur; The arc section that above-mentioned segmentation has a different curvature has very significantly benefit, as install very well, long service life, and the above-mentioned activities with groove of recess of cutting also can accomplish that a step cuts out, the cutting of general groove all needs repeatedly cutting moulding.
Above-mentioned arc-shaped convex 4 is made of two sections different curvature radius arc sections, the radius of curvature of leading portion circular arc 6 is R3.0～R3.5, the radius of curvature of back segment circular arc 7 is R6.0～R6.8, and the radius of curvature of preferred leading portion circular arc 6 is R3.2, and the radius of curvature of back segment circular arc 7 is R6.3; Above-mentioned section circular arc intersection, front and back can produce an atomic little crossing protruding (not shown), though should intersect projection can not exert an influence to installation, but it is more safe to be provided with a flat segments transition in arc section intersection in twos, and the length of this flat segments is about about 0.1～0.05mm.
Above-mentioned arc-shaped convex 4 is made of three sections different curvature radius arc sections, and the radius of curvature of leading portion circular arc 6 is R3.0～R3.5, and the radius of curvature of stage casing circular arc 8 is R3.3～R3.8, and the radius of curvature of back segment circular arc 7 is R6.0～R6.8; The radius of curvature of preferred leading portion circular arc 6 is R3.2, the radius of curvature of stage casing circular arc 8 is R3.5, the radius of curvature of back segment circular arc 7 is R6.3, press the arc-shaped convex 4 of the different curvature radius of above-mentioned three sections settings, more smooth and easy and posterior segment can not produce extruding to the lower wall of groove 2 during installation in rotation assembly unit process, promptly can not make the lower wall of groove 2 produce distortion and produce the stress that distortion causes, and the setting of posterior segment (8,7) is that contact point with the upper surface of two floor board block, 1 splicing is the center of circle.
The intersection point of above-mentioned leading portion circular arc 6 and back segment circular arc 7 or stage casing circular arc 8 is positioned near the minimum point of arc-shaped convex 4, and gradually wide arc-shaped gaps 9 is from the bottom to top arranged between the bottom of leading portion circular arc 6 and groove 2; Gradually wide arc-shaped gaps 9 can reduce the issuable excessive stresses of pulling force where necessary as holding dirt or holding glue and the spatial accommodation of small expansion or contraction, improves application life and reduces the distortion on floor; But the minimum point mutual dislocation of the minimum point of above-mentioned arc-shaped convex 4 and corresponding circular arc-shaped recess 5, the minimum point of arc-shaped convex 4 is positioned at the outside of the minimum point of corresponding circular arc-shaped recess 5, and between the bottom of described leading portion circular arc 6 and groove 2 gradually wide arc-shaped gaps 9 is arranged, the minimum point of mutual dislocation can make the mutual snap close ability of two floor board block be further enhanced.
