The specific embodiment

See also Fig. 1, floor of the present utility model automatic locking bayonet unit comprises a main part 15 and box body portion 8, upper surface at main part 15 is provided with mortise structure 10, this mortise structure 10 is trapezoidal, its central authorities offer two parallel stria 10a, 10b along the axis direction of bayonet unit, central authorities at main part 15 offer rectangle displacement aperture 12, and this hole is combined by two up big and down small rectangular openings.Also respectively establish a projection 9a, 9b at box body 8 and both sides.In addition, also establish a long and narrow repair demolition groove 11 on the surface of main part 15, diagram is the position at nearly box body 8.

Consider the installation of pipeline, below main part 15, offer hole slot 14,15.

Fig. 3,4 further illustrates the structure of floor slice to be installed, a long straight tenon 19 is established in one side end face of floor slice 26, the opposite side end face is established the tongue-and-groove 22 of a horizontal direction, and the length of tenon 19 is greater than the degree of depth of tongue-and-groove 22, the lower surface 20 that floor slice 26 is positioned at tenon 19 is constant slope, the lower surface 23 of the tongue-and-groove 22 of its opposite side also is constant slope, and its gradient with fall the inclined-plane of trapezoidal mortise structure 10 and coincide.

During installation, bayonet unit of the present utility model is placed on the ground, fix this device by rectangle displacement aperture 12 usefulness screws, bayonet unit and ground arch camber so both can have been prevented, the distortion on floor can be effectively controlled in the identical direction displacement of maximum, force direction that bayonet unit is expanded along the floor.Two bayonet units are when connecting, one of them box body 8 is snapped in the indent zone 16 of another bayonet unit, be inserted in spring on the protruding 8a in box body and indent zone and the 16a, and the projection 9 of a bayonet unit inserts in the shrinkage pool 17 of another bayonet unit.In addition,, its box body 8 is made the T font in order to make two connections that bayonet unit is more firm, and the front end broad, corresponding indent zone 16 also is similar T shape, so the box body 8 of one of them bayonet unit snaps in another difficult disengagement of 16 backs, indent zone.
