Description

A kind of checkered plate

Technical field

The utility model relates to a kind of anti-skid device, relates in particular to a kind of checkered plate of using on a kind of construction machinery and equipment.

Background technology

At present, the checkered plate of using on the existing construction machinery and equipment is the hole clipping that offers diamond shaped on steel plate, the step block of nonslipping spur is also made diamond shaped, like this when assembling, the step block of nonslipping spur passes through hole, make the draw-in groove on the nonslipping spur stick in the hole clipping of diamond shaped, in actual fabrication, if the step block of nonslipping spur is bigger than hole clipping, need it be sticked into very big thrust during installation, if and the step block of nonslipping spur is littler than hole clipping, drop out hole clipping after the installation easily, not only installation difficulty is big but also might cause step block to come off.

Summary of the invention

The purpose of this utility model is to provide a kind of easy for installation, checkered plate that the back difficult drop-off is installed.

In order to achieve the above object, the technical solution of the utility model is: a kind of checkered plate, comprise substrate and rubber antiskid piece, offer a plurality of hole clippings on the described substrate, the rubber antiskid piece comprises step block and cushion block, has draw-in groove between step block and the cushion block, the rubber antiskid piece is fixedly connected on the substrate with engaging of hole clipping on the substrate by draw-in groove, described step block is a rhombogen, hole clipping on the described substrate shape that assumes diamond in shape, corresponding both faces all has the projection of extending to hole clipping central authorities on the hole clipping wall on the described substrate.

All has the projection of extending on each side of hole clipping wall on the described substrate to hole clipping central authorities.

The hole clipping of described substrate has four summits that are complementary with step block rhombogen summit, and described projection is the projection that is linked to each other and formed by the straight sided of passing through two α in a certain angle between adjacent two summits.

The hole clipping of described substrate has four summits that the summit with the step block rhombogen is complementary, and described projection is the projection that links to each other and form by cambered surface by between adjacent two summits.

Angle α between described two straight sided is 135 ° ~ 175 °.

Has pit on the end face of the step block of described rubber antiskid piece.

After adopting said structure, the shape because the hole clipping on the described substrate assumes diamond in shape, corresponding both faces all has the projection of extending to hole clipping central authorities on the hole clipping wall on the described substrate, when engaging is installed, because the effect of projection is arranged, make that step block and substrate can firm being fastened togather, step block can be made with hole clipping equally big or small, pass hole clipping during installation easily, easy for installation, and corresponding both faces all has the projection of extending to hole clipping central authorities, and it is tighter to make that substrate and nonslipping spur engage, can skew back.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Shown in Fig. 1 ~ 5, a kind of checkered plate of the present utility model, comprise substrate 1 and rubber antiskid piece 2, offer a plurality of hole clipping 1-1 on the described substrate 1, rubber antiskid piece 2 comprises step block 2-1 and cushion block 2-2, has draw-in groove 2-3 between step block 2-1 and the cushion block 2-2, rubber antiskid piece 2 is fixedly connected on the substrate 1 with engaging of hole clipping 1-1 on the substrate 1 by draw-in groove 2-3, described step block 2-1 is a rhombogen, hole clipping 1-1 on the described substrate 1 shape that assumes diamond in shape, corresponding both faces all has the protruding 1-1-1 that extends to hole clipping 1-1 central authorities on the hole clipping 1-1 wall on the described substrate 1, like this can better be with

substrate

1 and 2 firm being connected of rubber antiskid piece, the utility model also can adopt the mode that all has the protruding 1-1-1 that extends to hole clipping 1-1 central authorities on each side of the hole clipping 1-1 wall on the substrate 1 to reach the purpose of firm connection substrate 1 and rubber antiskid piece 2 certainly.

Shown in Fig. 2,3, the hole clipping 1-1 of described substrate 1 has four summit 1-1-2 that are complementary with step block 2-1 rhombogen summit, described protruding 1-1-1 is the projection that is linked to each other and formed by the straight sided 1-1-3 that passes through two α in a certain angle between adjacent two summit 1-1-2, makes things convenient for die sinking and making like this.

Shown in Fig. 4,5, in order to make substrate 1 engage with rubber antiskid piece 2, rubber antiskid piece 2 can not wear and tear, the utility model adopts the hole clipping 1-1 of described substrate 1 to have four summit 1-1-2 that the summit with step block 2-1 rhombogen is complementary, and described protruding 1-1-1 is the projection that links to each other and form by cambered surface 1-1-4 by between adjacent two summit 1-1-2.

Shown in Fig. 2,3, in order to guarantee the power that engages between substrate 1 and the rubber antiskid piece 2, the angle α between described two straight sided 1-1-3 is 135 ° ~ 175 °.

As shown in Figure 1, have pit 2-4 on the end face of the step block 2-1 of described rubber antiskid piece 2, conveniently stripped.
