Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a crawler bolt. Background Technique

[0002] The crawler bolt is an important component for connecting crawler plates. It not only needs to firmly connect the crawler plates, but also move with the friction between the crawler plates and the ground. Its performance directly affects the performance of belt machines such as bulldozers and rollers. In the connection and fastening of crawler plates and track chain assemblies, high-strength bolts are mostly used. During the use of crawler bolts, due to the need to move with the friction between the crawler plates and the ground, they are prone to loosening. In view of the above situation, technological innovation is carried out on the basis of existing crawler bolts. Content of the Utility Model

[0003] The purpose of the utility model is to provide a crawler bolt to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a crawler bolt, including:

[0005] The crawler bolt, an installation ring is arranged on the outer side wall of the bolt head of the crawler bolt. A first sliding groove is opened at the bottom of the installation ring, and guiding grooves are uniformly opened on the inner side wall of the first sliding groove. Anti-slip teeth are uniformly arranged at the bottom of the bolt head of the crawler bolt. The bottom of the installation ring is flush with the bottom of the bolt head of the crawler bolt. Among them: a connection component is placed in the first sliding groove, and an anti-slip component is placed at the bottom of the connection component.

[0006] Preferably, the connection component includes springs uniformly arranged at the top of a second connection ring. A first annular sliding groove is opened at the bottom of the second connection ring, and a second annular sliding groove is opened at the top of the first annular sliding groove.

[0007] Preferably, the anti-slip component includes a first connection ring. A rotating ring is arranged at the top of the first connection ring, a limiting ring is arranged at the top of the rotating ring, and an anti-slip ring is arranged at the bottom of the first connection ring.

[0008] Preferably, the second connection ring is arranged in the first sliding groove of the installation ring, and the tops of the springs are uniformly arranged at the top of the inner side wall of the first sliding groove of the installation ring.

[0009] Preferably, the rotating ring is arranged in the first annular sliding groove, and the limiting ring is arranged in the second annular sliding groove.

[0010] Preferably, limiting blocks are uniformly arranged on the outer side wall of the second connection ring, and the limiting blocks are arranged in the guiding grooves.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] In the present utility model, after the crawler bolt is connected to the crawler plate, the anti-slip ring will be in contact with the crawler plate. At this time, when the crawler bolt is rotated continuously, the anti-slip ring and the first connecting ring will not rotate synchronously with the crawler bolt under the influence of the limiting ring and the rotating ring, thereby reducing the sliding friction between the anti-slip ring and the crawler plate, and further reducing the wear of the anti-slip ring when installing the crawler bolt, so as to improve the service life of the anti-slip ring.

[0013] When the crawler bolt is tightened, the spring, through its own resilience, reversely presses the second connecting ring, thereby making the anti-slip ring fit tightly with the crawler plate. At this time, through the anti-slip ring and the anti-slip teeth, stable anti-slip performance can be provided after the crawler bolt is tightened, thus ensuring the use reliability of the crawler bolt after installation.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 4, A crawler bolt, including a crawler bolt 1. An installation ring 2 is fixedly arranged on the outer side wall of the screw head of the crawler bolt 1. A first chute is opened at the bottom of the installation ring 2. Guide grooves are evenly opened on the inner side wall of the first chute. Anti-slip teeth 11 are evenly fixedly arranged at the bottom of the screw head of the crawler bolt 1. The anti-slip teeth 11 can provide anti-slip performance for the crawler bolt 1 after it is tightened. The bottom of the installation ring 2 is flush with the bottom of the screw head of the crawler bolt 1. Among them: A connection component is placed in the first chute, and an anti-slip component is placed at the bottom of the connection component. The connection component includes springs 23 evenly fixedly arranged at the top of a second connection ring 24. A first annular chute is opened at the bottom of the second connection ring 24, and a second annular chute is opened at the top of the first annular chute. The anti-slip component includes a first connection ring 22. A rotating ring 27 is fixedly arranged at the top of the first connection ring 22. A limiting ring 26 is fixedly arranged at the top of the rotating ring 27. An anti-slip ring 21 is fixedly arranged at the bottom of the first connection ring 22. The second connection ring 24 is slidably arranged in the first chute of the installation ring 2. The tops of the springs 23 are evenly fixedly arranged at the top of the inner side wall of the first chute of the installation ring 2. The rotating ring 27 is rotatably arranged in the first annular chute, and the limiting ring 26 is rotatably arranged in the second annular chute. Limiting blocks 25 are evenly fixedly arranged on the outer side wall of the second connection ring 24. The limiting blocks 25 are slidably arranged in the guide grooves. The limiting blocks 25 assist the second connection ring 24 to move up and down stably.

[0021] Working principle: When the crawler bolt 1 is connected to the crawler plate, the anti-slip ring 21 will be in contact with the crawler plate. At this time, continuing to rotate the crawler bolt 1 will drive the installation ring 2 and the second connection ring 24 to rotate synchronously, while the anti-slip ring 21 and the first connection ring 22 will not rotate synchronously with the crawler bolt 1 due to the influence of the limiting ring 26 and the rotating ring 27, thereby reducing the sliding friction between the anti-slip ring 21 and the crawler plate, and further reducing the wear of the anti-slip ring 21 when installing the crawler bolt 1, so as to improve the service life of the anti-slip ring 21. When the crawler bolt 1 is tightened, the second connection ring 24 and the limiting blocks 25 are squeezed and move into the first chute of the installation ring 2, and the second connection ring 24 squeezes the springs 23. At this time, the springs 23, through their own resilience, reversely squeeze the second connection ring 24, thereby making the anti-slip ring 21 fit tightly with the crawler plate. At this time, through the anti-slip ring 21 and the anti-slip teeth 11, stable anti-slip performance can be provided for the crawler bolt 1 after it is tightened, thereby ensuring the use reliability of the crawler bolt 1 after installation.
