Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, and in particular to an anti-track slip pin. Background Technology

[0002] In modern mechanical engineering, especially in the fields of heavy equipment, vehicles, and construction machinery, the pin, as a critical connecting component, directly affects the operational safety and efficiency of the entire equipment. As a core component in tracked equipment, the anti-tracking pin bears the important responsibilities of transmitting torque, supporting weight, and ensuring smooth track operation. However, traditional track pin designs often suffer from the problem of loosening retaining rings. This not only affects the pin's tightening effect but may also cause the pin to shift under extreme operating conditions, leading to equipment failure or even safety accidents. Traditional anti-tracking measures mostly involve only retaining rings, but after long-term use, due to factors such as vibration, wear, or material fatigue, the retaining rings may gradually loosen, reducing the reliability of the connection.

[0003] Therefore, it is necessary to design an anti-track slippage pin. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-track slippage pin.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-track shifting pin includes a right track link, a left track link, and a pin. The pin passes through the right track link and the left track link. A stop block is fixed at one end of the pin. An annular groove is provided on the side wall of the pin near the other end. An anti-track shifting mechanism is provided inside the annular groove.

[0007] As a further improvement of this utility model, the anti-slip mechanism includes a retaining ring, a fixing block fixed on one side wall of the retaining ring, a connecting block fixed on the other side wall of the retaining ring, a connecting plate sleeved on the outer side of the fixing block, a connecting shaft passing through the fixing block, the connecting shaft being rotatably connected to the fixing block, the two ends of the connecting shaft passing through the two side walls of the connecting plate respectively, and the connecting shaft being fixedly connected to the connecting plate, a connecting groove cooperating with the connecting block passing through the side wall of the connecting plate, an installation groove passing through the inner top wall of the connecting groove, and a snap-fit ​​structure inside the installation groove.

[0008] As a further improvement of this utility model, the snap-fit ​​structure includes a pull plate disposed inside the mounting groove, a snap block fixed at the lower end of the pull plate, a snap groove that mates with the snap block at the upper end of the connecting block, a spring fixed at the upper end of the snap block, and the end of the spring away from the snap block fixed to the inner top wall of the mounting groove.

[0009] As a further improvement of this utility model, the number of springs is two, and the two springs are symmetrically arranged on both sides of the pull plate.

[0010] As a further improvement of this utility model, the end of the card block away from the pull plate is an arc-shaped surface.

[0011] As a further improvement of this utility model, grooves are provided on both sides of the right chain link, and the pin is located inside the groove.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a retaining ring, connecting plate, connecting block, connecting groove and snap-fit ​​structure, the retaining ring can be further connected and locked, effectively preventing the retaining ring from opening or loosening due to external factors, thereby significantly improving the stability of the pin's anti-slip mechanism.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5An anti-track pin includes a right track link 1, a left track link 2, and a pin 4. The pin 4 passes through the right track link 1 and the left track link 2. A stop block 5 is fixed at one end of the pin 4. An annular groove 6 is provided on the side wall of the pin 4 near the other end. An anti-tracking mechanism is provided inside the annular groove 6. Grooves 3 are provided on the opposite side walls of the right track link 1. The pin 4 is located inside the groove 3.

[0022] The anti-slip mechanism includes a retaining ring 7, a fixing block 8 fixed on one side wall of the retaining ring 7, and a connecting block 11 fixed on the other side wall of the retaining ring 7. A connecting plate 10 is sleeved on the outside of the fixing block 8. A connecting shaft 9 passes through the fixing block 8 and is rotatably connected to the fixing block 8. Both ends of the connecting shaft 9 pass through the two side walls of the connecting plate 10 respectively, and the connecting shaft 9 is fixedly connected to the connecting plate 10. A connecting groove 12 that mates with the connecting block 11 passes through the side wall of the connecting plate 10. An installation groove 13 passes through the inner top wall of the connecting groove 12. The installation groove 13 has a snap-fit ​​structure inside.

[0023] In this utility model, the snap-fit ​​structure includes a pull plate 14 disposed inside the mounting groove 13, a snap block 16 fixed at the lower end of the pull plate 14, a snap groove 15 that mates with the snap block 16 at the upper end of the connecting block 11, a spring 17 fixed at the upper end of the snap block 16, and the end of the spring 17 away from the snap block 16 fixed on the inner top wall of the mounting groove 13. There are two springs 17, which are symmetrically arranged on both sides of the pull plate 14. The end of the snap block 16 away from the pull plate 14 is an arc-shaped surface.

[0024] In use, the pin 4 is inserted into the right chain link 1 and the left chain link 2. Then, the retaining ring 7 is fitted into the annular groove 6. Next, the connecting plate 10 is rotated so that the connecting block 11 is inserted into the connecting groove 12. Then, the locking block 16 is inserted into the groove 15. The elastic force of the spring 17 acts on the locking block 16, so that the locking block 16 is stably locked in the groove 15. This ensures a stable connection between the connecting block 11 and the connecting plate 10, further locking the retaining ring 7 and effectively preventing the retaining ring 7 from opening or loosening due to external factors. This significantly improves the anti-slip stability of the pin 4. When the pin 4 needs to be pulled out, first pull the pull plate 14 to move the locking block 16 out of the groove 15. Then, rotate the connecting plate 10 to move the connecting block 11 out of the connecting groove 12. Then, the retaining ring 7 can be opened to release the restriction on the pin 4, and the pin 4 can be pulled out.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
