[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 5 The illustrated type of washerless bolt with damping texture on the bearing surface includes a bolt body 1. A fixing washer 2 is fixedly installed at the bottom of the bolt body 1. The bottom of the fixing washer 2 is evenly provided with positioning grooves 3. A fixing rod 4 is fixedly connected inside the positioning grooves 3. A compression spring 5 is sleeved on the outside of the fixing rod 4. A threaded rod 6 is fixedly connected to the bottom of the bolt body 1. An anti-loosening washer 7 is installed directly below the fixing washer 2. A damping texture body 13 is provided at the bottom of the fixing washer 2 and above the anti-loosening washer 7. An anti-slip texture 14 is provided on the lower side of the anti-loosening washer 7.

[0025] Specifically: A positioning groove 3 is provided at the bottom of the fixing gasket 2 to enhance the stability and reliability of the connection. A fixing rod 4 and a compression spring 5 are installed inside the positioning groove 3. When the bolt body 1 is tightened, the compression spring 5 generates a continuous elastic force. This elastic force ensures that the threaded connection between the nut and the threaded rod 6 always maintains a certain friction, thereby forming a resistance torque to effectively prevent the nut from loosening under vibration or external force. In addition, an anti-loosening gasket 7 is installed at the bottom of the positioning groove 3, and a damping texture body 13 is provided on the side of the positioning groove 3 close to the anti-loosening gasket 7, so that the positioning groove 3 and the anti-loosening gasket 7 can fit more tightly during installation, further improving the overall stability. At the same time, an anti-slip texture 14 is provided below the anti-loosening gasket 7. When positioning the equipment, one side of the anti-slip texture 14 will make close contact with the positioning surface, thereby greatly enhancing the firmness and stability of the positioning, increasing the convenience of the positioning component in the later assembly and disassembly process, and extending the overall service life of the positioning component.

[0028] As a preferred embodiment, the bolt body 1 and the fixed washer 2 are integrally arranged; further, the bolt body 1 and the fixed washer 2 are designed as an integrated structure, which makes them functionally closely connected, and when external force is applied to the bolt body 1 for moving or tightening operation, the fixed washer 2 rotates synchronously, without the need for additional operation of the washer. This integrated design not only simplifies the installation process and improves work efficiency, but also ensures the stability and reliability of the connection between the threaded rod 6 and the washer, effectively avoiding the loosening or misalignment problems that may occur in traditional split design.

[0029] As a preferred embodiment, a positioning through hole 8 is provided in the middle of the anti-escape washer 7, which is sleeved outside the threaded rod 6; further, a precise positioning through hole 8 is specially designed on the anti-escape washer 7, which is tightly sleeved outside the threaded rod 6. This not only enhances the connection stability between the anti-escape washer 7 and the threaded rod 6, but also significantly improves the firmness of the overall structure. Through the close cooperation of the positioning through hole 8 and the threaded rod 6, the displacement or falling of the washer caused by vibration or external force during use is effectively prevented, thereby ensuring the long-term stable operation of the equipment.
