[0030] Example

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the problem that when installing automobile parts, some parts are designed with countersunk holes in order to prevent the bolt head from protruding from the surface. The bolt needs to be inserted into the countersunk hole and then aligned with the bolt hole for screwing. During the bolt installation process, there is a lack of a positioning mechanism, and the bolt body is prone to tilt before the screwing operation, resulting in installation difficulties and low efficiency. The overall idea is as follows: an anti-fatigue automobile bolt that is easy to disassemble and assemble, comprising a bolt body 11, the outer surface of which is fixedly connected with a rectangular flower The outer surface of the bolt body 11 is slidably connected with a circular sleeve 13, and a slide groove 14 is provided inside the circular sleeve 13. The slide groove 14 is adapted to the rectangular pattern 12. The upper end of the bolt body 11 is fixedly connected with a mounting mechanism, and the mounting mechanism includes a bolt head 15. The bolt head 15 is fixedly connected to the upper end of the bolt body 11. Six mounting grooves 16 are provided inside the bolt head 15. The six mounting grooves 16 are equally divided inside the bolt head 15. Six magnetic blocks 17 are fixedly connected to the bolt head 15. The six magnetic blocks 17 are respectively fixedly connected to the six mounting grooves. 16 inside, the outside of the bolt body 11 contains a rectangular pattern 12 (the rectangular pattern 12 is rolled out on the surface of the bolt body 11 by a knurling cutter during the production process of the bolt body 11). When the bolt body 11 is taken and moved, the rectangular pattern 12 increases the friction with the operator's hand, making it less likely to fall when taken. Before the bolt body 11 is screwed for installation, the annular sleeve 13 is slidably sleeved on the outside of the bolt body 11. The rectangular pattern 12 on the outside of the bolt body 11 is adapted to the slide groove 14 provided in the annular sleeve 13, and the annular sleeve 13 is tightly connected Connected to the outside of the rectangular pattern 12, the outer ring size of the circular sleeve 13 fits the inner wall of the countersunk hole circular groove that needs to be extended. By connecting the circular sleeve 13 outside the bolt body 11, it plays a role in rapid positioning during the bolt installation process, avoiding the bolt body 11 from tilting during the screwing operation. The magnetic block 17 is installed in the installation groove 16 by welding. When the tool is sleeved on the outside of the bolt head 15, it is adsorbed and fitted into the tool through the installation groove 16. The tool is not easy to fall off during the screwing operation, further assisting the installation operation to achieve the effect of easy disassembly and assembly.

[0032] Two step grooves 18 are provided inside the bolt head 15, and a rubber ring 19 is sleeved on the outer surface of the bolt body 11. The rubber ring 19 is located at the lower end of the bolt head 15. Align the bolt body 11 with the component to be connected so that it is completely aligned with the bolt hole. Use a tool (such as a socket wrench) to sleeve it over the bolt head 15, and screw it to drive the bolt body 11 to tighten it in the bolt hole to connect and install the components. Before the bolt body 11 is installed and used, sleeve the rubber ring 19 over the bolt body 11 to reduce the impact force on the bolt and slow down the generation of fatigue.

[0033] The upper end of the rubber ring 19 is fixedly connected to two circular blocks 21, both of which are stepped. The two circular blocks 21 are respectively sleeved inside the two step grooves 18, and the magnetic block 17 is installed in the installation groove 16 by welding. When the tool is sleeved on the outside of the bolt head 15, it is adsorbed and fitted into the tool through the installation groove 16. The tool is not easy to fall off during the screwing operation, which further assists the installation operation and achieves the effect of easy disassembly and assembly. Before the screwing installation work, the rubber ring 19 is sleeved on the outside of the bolt body 11 (the rubber ring 19 is located at the lower end of the bolt head 15 and the upper end of the circular sleeve 13 is between the two). The circular ring block 21 at the upper end of the rubber ring 19 is aligned and inserted into the step groove 18, and the rubber ring 19 is screwed clockwise so that the circular ring block 21 is inserted into the groove of the step groove 18 (the step groove 18 is shaped like a step and will form a groove in the bolt head 15 according to its own shape). The circular ring block 21 is limited by the step groove 18 to ensure its stability after installation. The rubber ring 19 is connected to the outer shell of the bolt body 11 to play a buffering and vibration reduction role. The rubber ring 19 is an elastic material that can absorb and disperse these external forces, reduce the dynamic load borne by the bolt body 11, reduce the impact force on the bolt body 11, and slow down the generation of fatigue.

[0034] In response to the problems existing in the prior art, the present invention provides an anti-fatigue automobile bolt that is easy to disassemble and assemble. Before the bolt body 11 is screwed for installation, the annular sleeve 13 is slidably sleeved on the outside of the bolt body 11. The annular sleeve 13 is tightly connected to the outside of the rectangular pattern 12. The outer ring size of the annular sleeve 13 fits the inner wall of the countersunk hole groove that needs to be extended. By sleeve-fitting the annular sleeve 13 on the outside of the bolt body 11, it plays a role in rapid positioning during the bolt installation process, avoiding tilting of the bolt body 11 during the screwing operation. When the tool is sleeved on the outside of the bolt head 15, it is adsorbed and fitted into the tool through the installation groove 16. The tool is not easy to fall off during the screwing operation, further assisting the installation operation, achieving the effect of easy disassembly and assembly.

[0035] Working principle:

[0036] The first step is to align the bolt body 11 with the component to be connected so that it is completely aligned with the bolt hole. Use a tool (such as a socket wrench) to cover the outside of the bolt head 15, and twist it to drive the bolt body 11 to tighten it in the bolt hole to connect and install the components. Before the bolt body 11 is installed and used, the rubber ring 19 is placed on the outside of the bolt body 11. The rubber ring 19 reduces the impact force on the bolt and slows down the generation of fatigue.

[0037] The second step is that the outer surface of the bolt body 11 contains a rectangular pattern 12 (the rectangular pattern 12 is rolled out on the surface of the bolt body 11 by a knurling cutter during the production of the bolt body 11). When the bolt body 11 is picked up and moved, the rectangular pattern 12 increases the friction with the operator's hand, which is not easy to fall off when picked up. Before the bolt body 11 is screwed for installation, the annular sleeve 13 is slidably sleeved on the outside of the bolt body 11. The rectangular pattern 12 on the outside of the bolt body 11 is adapted to the slide groove 14 opened in the annular sleeve 13, and the annular sleeve 13 is tightly connected to the outside of the rectangular pattern 12. The outer ring size of the annular sleeve 13 is fitted with the inner wall of the countersunk hole groove that needs to be extended. By sleeved with the annular sleeve 13 outside the bolt body 11, it plays a role of rapid positioning during the bolt installation process, avoiding the bolt body 11 from tilting during the screwing operation, and the magnetic block 17 is installed in the installation groove 16 by welding. When the tool is sleeved on the outside of the bolt head 15, it is inserted through the installation groove 16 The rubber ring 19 is sucked and fits in the tool, and the tool is not easy to fall off during the screwing operation, which further assists the installation operation and achieves the effect of easy disassembly and assembly. Before screwing and installing, the rubber ring 19 is sleeved on the outside of the bolt body 11 (the rubber ring 19 is located at the lower end of the bolt head 15 and the upper end of the annular sleeve 13, and is between the two). The circular ring block 21 at the upper end of the rubber ring 19 is aligned and inserted into the step groove 18, and the rubber ring 19 is screwed clockwise so that the circular ring block 21 is sleeved into the groove of the step groove 18 (the step groove 18 is shaped like a step and will form a groove in the bolt head 15 according to its own shape). The circular ring block 21 is limited by the step groove 18 to ensure its stability after installation. By sleeved with the rubber ring 19 on the outer side of the bolt body 11, it plays a role of buffering and vibration reduction. The rubber ring 19 is an elastic material that can absorb and disperse these external forces, reduce the dynamic load borne by the bolt body 11, reduce the impact force received by the bolt body 11, and slow down the generation of fatigue.

[0038] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
