It acts as a supporting skeleton, directly meshing with the machine drive wheel, transmitting power and supporting the weight of the machine. The design and shape of the rubber track tooth is one of the key elements in the design of the rubber track, and has an important impact on the overall performance and function of the track.

The utility model comprises a bridge, a positioning block is convexly provided on the back of the bridge, a plurality of anti-skid convex columns are provided on the end of the positioning block away from the bridge, positioning teeth are provided on both sides of the bridge, and the positioning teeth extend in a direction away from the bridge. The positioning teeth, positioning blocks and anti-skid convex columns provided therein can enhance the matching strength between the iron tooth and the rubber track, play an anti-flipping effect, and thus make the use of the track more stable.

[0004] However, in the process of using the above scheme, since the positioning teeth, positioning blocks and anti-skid bosses are directly installed on the bridge, when facing the installation process of different rubber tracks, the track teeth can only be processed according to the required size, and if there is an error in the processed track teeth, it is easy to cause the two to be loose or unable to be installed. Therefore, an anti-flipping durable track tooth is proposed. Utility Model Content

[0007] By adopting the above technical solution, the bidirectional screw is manually rotated so that the bidirectional screw can push the two sliders to move respectively when rotating, and the movement of the slider drives the upper tooth block to move, thereby adjusting the spacing between the two tooth blocks, which facilitates the subsequent installation of rubber tracks of different sizes.

[0008] Optionally, one end of the bidirectional screw is rotatably mounted on the slide slot, and the other end passes through the bridge and is rotatably mounted on the other side of the slide slot via a rotating shaft.

[0010] Optionally, a slide rail matching the limit nut is provided at the connection between the bridge and the limit nut, and the slide rail is provided on the bridge.

[0011] By adopting the above technical solution, the slide rail can realize the anti-blocking effect on the limit nut when the tooth block moves, preventing the limit nut from getting stuck on the bridge, and the fixing effect of the connecting plate and the tooth block can be achieved through the limit nut and the anti-slip gasket.

[0012] Optionally, two groups of plastic limiting rings are sleeved on the outer side of the bidirectional screw, and threads matching the bidirectional screw are arranged on the inner side of the plastic limiting rings.

[0016] Optionally, a plurality of groups of anti-skid columns are fixedly mounted on the bottom end surface of the block.

[0017] By adopting the above technical solution, the anti-skid column can achieve anti-skid performance between the blocking block and the rubber track.

[0018] Optionally, limit blocks are fixedly installed at both ends of the bridge.

[0019] By adopting the above technical solution, the limiting block can further improve the installation between the bridge and the rubber track.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model artificially rotates the bidirectional screw so that the bidirectional screw can push the two sliders to move respectively when rotating, and the movement of the slider drives the upper tooth block to move, thereby adjusting the distance between the two tooth blocks, which is convenient for the subsequent installation of rubber tracks of different sizes.

The bidirectional screw 5 is rotated so that the bidirectional screw 5 can push the two sliders 4 to move respectively when rotating, and the upper tooth block 2 is driven to move by the movement of the slider 4, so as to adjust the spacing between the two tooth blocks 2, and a connecting plate 6 is fixedly installed on one side of the tooth block 2, a limiting nut 7 is installed on the middle thread of the connecting plate 6, and an anti-slip gasket 8 is fixedly installed below the limiting nut 7, and the anti-slip gasket 8 is arranged on the connecting plate 6, and a limiting block is installed on the other end of the limiting nut 7. The limiting block is fixedly installed On the inner side of the slide rail 9, one end of the bidirectional screw 5 is rotatably installed on the slide groove 3, and the other end passes through the bridge 1 and is rotatably installed on the other side of the slide groove 3 through the rotating shaft. The slide rail 9 can realize the anti-blocking effect of the limit nut 7 when the tooth block 2 moves, so as to prevent the limit nut 7 from being stuck on the bridge 1, and the fixing effect of the connecting plate 6 and the tooth block 2 can be achieved through the limit nut 7 and the anti-slip gasket 8. A slide rail 9 matching the limit nut 7 is provided at the connection between the bridge 1 and the limit nut 7. The slide rail 9 is provided on the bridge 1, and two groups of plastic limit rings 10 are provided on the outer side of the bidirectional screw 5. The inner side of the plastic limit ring 10 is provided with a thread matching the bidirectional screw 5. The plastic limit ring 10 can achieve a limiting effect on the bidirectional screw 5 through the inner thread, so that the bidirectional screw 5 can be fixed.

[0031] Reference Figure 1 , Figure 2 and Figure 4 A block 11 is fixedly installed at the bottom of the bridge 1, and an active cavity 12 is opened on the outer side of the block 11. A spring 13 is fixedly installed inside the active cavity 12. The other side of the spring 13 is fixedly connected to a limiting plate 14. The block 11 can achieve a clamping effect with the rubber track, so that the overall structure is installed on the track, and when the block 11 is installed on the rubber track, the limiting plate 14 will pop out and be stuck on the rubber track all the time, so that the two always keep a tightly fitted state, thereby achieving an anti-flip effect on the track iron teeth, and a plurality of groups of anti-skid columns 15 are fixedly installed on the bottom end surface of the block 11. Limited block 16 are fixedly installed at both ends of the bridge 1, and the anti-skid column 15 can achieve anti-skid performance between the block 11 and the rubber track.

[0032] The implementation principle of the utility model is as follows: before the track iron teeth are installed on the rubber track, the bidirectional screw rod 5 is manually rotated according to the clamping position of the rubber track. When the bidirectional screw rod 5 is rotating, the bidirectional thread on its outer side will push or pull the two sliders 4 to make relative movement, and when the slider 4 moves, the tooth block 2 is driven to move, so that the sliding effect of the tooth block 2 in the slide groove 3 is achieved through the rotation of the bidirectional screw rod 5, and the distance between the two tooth blocks 2 is adjusted. When the tooth block 2 is adjusted, the plastic limiting ring 10 is directly placed on the outer side of the bidirectional screw rod 5 to limit the bidirectional screw 5. In the sliding process of the tooth block 2, the connecting plate 6 will also move with the movement of the tooth block 2, and the limiting nut 7 and the limiting block will also slide at the slide rail 9, and when the limiting nut 7 and the limiting block are After the positioning nut 7 is moved, the limiting nut 7 can be rotated to make the limiting nut 7 achieve the effect of downward extrusion through the limiting block threadedly connected thereto, so that the auxiliary fixing effect of the tooth block 2 can be achieved through the limiting nut 7, and then the overall structure can be installed with the rubber track. During the installation process, the clamping block 11 is installed inside the rubber track, and during the installation process of the clamping block 11, the limiting plate 14 outside the clamping block 11 will be squeezed by the spring 13. In this way, the connection between the limiting plate 14 and the rubber track is tighter through the squeezing of the limiting plate 14, and due to the elasticity of the spring 13, even if the two are worn out later, the spring 13 will make the limiting plate 14 fit the rubber track, thereby reducing the possibility of the track iron teeth driving the rubber track to flip.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
