[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0028] This application discloses an eccentric bolt.
[0029] Reference Figures 1-3An eccentric bolt includes a bolt head 1, a thread 2 on the bolt head 1 (the thread 2 assists in installation), a head plate 3 fixedly mounted on one end of the bolt head 1, and a reinforcing mechanism on the bolt head 1. The reinforcing mechanism increases the contact area and reduces the compressive stress on the bearing surface, thus protecting the surface of the connected parts and providing excellent durability. In strong vibration environments, the anti-loosening washer effectively maintains the clamping force of the connected parts, preventing bolt loosening due to vibration. A circular groove 7 is provided on the bolt head 1, and the bolt... The head 1 is screwed to the tail end with a nut 4, which is located on the thread 2. A first washer 5 is set on one side of the nut 4, and multiple corresponding first mounting seats 8 are fixedly installed on the first washer 5. Multiple corresponding first reinforcing teeth 9 are fixedly installed on one side of each of the multiple first mounting seats 8. A first buffer plate 6 is set on one side of the first washer 5. Multiple first openings 10 are opened on the first buffer plate 6, and the multiple first openings 10 are all set to correspond to the corresponding first reinforcing teeth 9. The width and length of the multiple first openings 10 and the corresponding first reinforcing teeth 9 are the same.
[0030] In use, a circular groove 7 is cut into the existing bolt head 1 so that the bolt head 1 can be inserted and positioned. The nut 4 is then screwed on at the end to complete the overall installation and positioning. This improves the convenience and flexibility of installation and further enhances the stability and firmness of the installation.
[0031] Reference Figures 2-4 The reinforcement mechanism includes a second washer 11 sleeved on the bolt head 1, multiple second mounting seats 13 fixedly installed at one end of the second washer 11, and multiple corresponding second reinforcing teeth 14 fixedly installed on one side of each of the multiple second mounting seats 13. By setting the second reinforcing teeth 14, the connector can be in contact, thereby increasing the contact area and thus improving the stability during installation. A second buffer plate 12 is set at one end of the second washer 11, and multiple corresponding second openings 15 are opened on the second buffer plate 12. Both the first buffer plate 6 and the second buffer plate 12 are slidably sleeved on the bolt head 1. Both the first buffer plate 6 and the second buffer plate 12 are made of rubber. Because both the first buffer plate 6 and the second buffer plate 12 are made of rubber, they have good elasticity and energy absorption capacity. They can absorb energy when the nut 4 is subjected to vibration, reduce loosening and vibration, and thus maintain a tight state, thereby further improving the stability after installation.
[0032] In use, the contact area is increased and the compressive stress on the bearing surface is reduced by the cooperation of the first reinforcing teeth 9 on the first washer 5, thereby protecting the surface of the connected parts. It also has excellent durability. In a strong vibration environment, the anti-loosening washer can effectively maintain the clamping force of the connected parts and prevent the bolts from loosening due to vibration. The first buffer plate 6 and the second buffer plate 12 made of rubber have good elasticity and energy absorption capacity. They can absorb energy when the nut 4 is subjected to vibration, reduce loosening and vibration, and maintain a tight state, thereby further improving the firmness after installation.
[0033] The implementation principle of an eccentric bolt in this application embodiment is as follows: When in use, firstly, a circular groove 7 is cut on the existing bolt head 1 so that the bolt head 1 can be placed in it and installed and positioned. Then, a nut 4 is screwed on the tail end to complete the overall installation and positioning. This can improve the convenience and flexibility of installation, and thus further improve the stability and firmness after installation.
[0034] Through the cooperation of the first reinforcing teeth 9 on the first washer 5, the contact area can be increased, the compressive stress on the bearing surface can be reduced, thereby protecting the surface of the connected parts. At the same time, it has excellent durability. In the strong vibration environment, the anti-loosening washer can effectively maintain the clamping force of the connected parts and prevent the bolts from loosening due to vibration. Through the first buffer plate 6 and the second buffer plate 12 made of rubber, it has good elasticity and energy absorption capacity. It can absorb energy when the nut 4 is subjected to vibration, reduce loosening and vibration, thereby maintaining a tight state, and further improving the firmness after installation.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
