[0002] A bolt is a common mechanical fastener, usually consisting of a head and a threaded rod. It is used in conjunction with a nut to fasten two parts with through holes.

[0003] During repeated disassembly and reassembly of bolts, the threads of the nut and bolt are prone to wear, stripping, or even scrapping due to misalignment, vibration, or external impact, which directly affects the service life and safety of the connector. In addition, after the bolt body is threadedly connected to the nut assembly, the bolt body will directly rub against the nut assembly during use, which will lead to increased wear on the external threads of the bolt body, thereby reducing the service life of the bolt body. Utility Model Content

It solves the technical problems of existing nuts and bolts whose threads are easily worn, stripped or even scrapped due to misalignment, vibration or external impact, which directly affects the service life and safety of the connecting parts. It also solves the technical problems that after the bolt body is threadedly connected to the nut assembly, the bolt body will directly rub against the nut assembly during use, which will lead to increased wear on the threads on the outside of the bolt body and thus reduce the service life of the bolt body.

[0005] The purpose of this utility model is achieved through the following means: a bolt whose threads are not easily damaged by repeated disassembly, comprising a bolt body, a nut assembly, and a bolt head, wherein the nut assembly is threadedly connected to the outside of the bolt body, the bolt head is assembled on the top of the bolt body, a rubber gasket is sleeved on the outside of the bolt body, a limit ring is assembled between the nut assembly and the bolt head, and T-shaped sliders are connected to both the upper and lower ends of the limit ring.

[0006] The top of the nut assembly is provided with a first annular groove, and the inner cavities of the first annular groove are provided with first snap-fit ​​grooves on both sides. The top left and right ends of the first annular groove are provided with first vertical grooves.

[0007] The bottom of the bolt head is provided with a second annular groove, the top of the inner cavity of the second annular groove is provided with a second vertical groove, and the outside of the second vertical groove is connected to a second snap-fit ​​groove.

[0008] Furthermore, the nut assembly is fitted with a hexagonal sleeve, and the hexagonal sleeve has anti-slip texture on its outer surface. The hexagonal sleeve facilitates the operation of the nut assembly by the operator, and the anti-slip texture improves the stability of the nut assembly during operation.

[0009] Furthermore, the top of the bolt head is provided with a plum blossom groove, and the outside of the bolt head is designed with rounded corners. The plum blossom groove makes it convenient for workers to drive the bolt head to move.

[0010] Furthermore, there are four sets of T-shaped sliders, which are respectively assembled at the upper and lower ends of the limiting ring, and the T-shaped sliders are slidably connected to the first and second locking grooves. The T-shaped sliders can slide in the inner cavities of the first and second locking grooves.

[0011] Furthermore, magnets are fitted to the outside of both the T-shaped slider and the first and second locking slots, and the T-shaped slider is attracted to the magnets on the outside of the first and second locking slots. The magnets can improve the stability of the T-shaped slider during use.

[0012] Furthermore, the top of the nut assembly is provided with a protrusion, the top of which contacts the bottom of the bolt head. The protrusion can prevent the bolt body from being connected to the nut assembly by a threaded connection.

[0013] The beneficial effects of this utility model are as follows: By adding a limiting ring, when the bolt body and the nut assembly are threadedly connected, the nut assembly and bolt head are automatically supported, avoiding direct friction between the bolt body and the nut assembly during use, which would increase wear on the external threads of the bolt body and reduce its service life. At the same time, by adding a T-shaped slider and the first and second locking grooves, when the limiting ring self-locks between the bolt body and the nut assembly, the position of the bolt body is automatically locked, thereby inhibiting the loosening of the bolt body, improving the overall stability of the device, and avoiding alignment deviation and vibration during use.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figure 1 and Figure 2 The specific implementation of this is a bolt that is not easily damaged by repeated disassembly, including a bolt body 1, a nut assembly 2 and a bolt head 3. The nut assembly 2 is threaded to the outside of the bolt body 1, the bolt head 3 is assembled on the top of the bolt body 1, a rubber gasket 4 is sleeved on the outside of the bolt body 1, a limit ring 5 is assembled between the nut assembly 2 and the bolt head 3, and T-shaped sliders 51 are connected to both the upper and lower ends of the limit ring 5.

[0022] The bolt body 1, nut assembly 2 and bolt head 3 are a common bolt in the prior art. The rubber washer 4 can support the nut assembly 2 and bolt head 3. The rubber washer 4 is made of wear-resistant silicone and the outer layer is made of polyurethane material with anti-slip stripes. It absorbs impact force through elastic deformation and reduces thread stress concentration. The limiting ring 5 can support the bolt head 3 and nut assembly 2.

[0023] The T-shaped slider 51 can slide in the inner cavity of the first locking groove 22 and the second locking groove 32, thereby locking the position of the bolt head 3. The first locking groove 22 and the second locking groove 32 are both C-shaped designs, and the two first locking grooves 22 and the two second locking grooves 32 are staggered.

[0024] Please refer to Figure 3 , Figure 4 and Figure 5 The top of the nut assembly 2 is provided with a first annular groove 23, and the inner cavity of the first annular groove 23 is provided with a first snap-fit ​​groove 22 on both sides. The top left and right ends of the first annular groove 23 are provided with a first vertical groove 21.

[0025] The bottom of the bolt head 3 is provided with a second annular groove 33, the top of the inner cavity of the second annular groove 33 is provided with a second vertical groove 31, and the outside of the second vertical groove 31 is connected to a second snap-fit ​​groove 32.

[0026] The nut assembly 2 is fitted with a hexagonal sleeve, and the hexagonal sleeve has anti-slip texture on its outside. The hexagonal sleeve makes it easy for the operator to drive the nut assembly 2 to move, and the anti-slip texture improves the stability of the nut assembly 2 during movement.

[0027] The top of the bolt head 3 is provided with a plum blossom groove, and the outside of the bolt head 3 is designed with rounded corners. The plum blossom groove makes it convenient for the operator to drive the bolt head 3 to move. There are four sets of T-shaped sliders 51, which are respectively assembled at the upper and lower ends of the limiting ring 5. The T-shaped sliders 51 are slidably connected with the first locking groove 22 and the second locking groove 32. The T-shaped sliders 51 can slide in the inner cavity of the first locking groove 22 and the second locking groove 32.

[0028] The T-shaped slider 51 is equipped with magnets on the outside of the first locking groove 22 and the second locking groove 32. The T-shaped slider 51 is attracted to the magnets on the outside of the first locking groove 22 and the second locking groove 32. The magnets can improve the stability of the T-shaped slider 51 during use. The top of the nut assembly 2 is provided with a protrusion. The top of the protrusion contacts the bottom of the bolt head 3. The protrusion can prevent the bolt body 1 from being connected to the nut assembly 2 by a threaded connection.

[0029] First, fix the position of the nut assembly 2. When using the bolt body 1, use external fastening tools such as bolts to rotate the bolt head 3 to drive the bolt body 1 into the nut assembly 2. When the bolt head 3 rotates to the limit position, it will be restricted from descending by the protrusion on the top of the nut assembly 2. At this time, the limiting ring 5 is raised and inserted into the inner cavity of the second ring groove 33. At this time, the two sets of T-shaped sliders 51 are respectively inserted into the inner cavities of the second vertical groove 31 and the first vertical groove 21. Then, the limiting ring 5 is rotated thirty degrees so that the T-shaped sliders 51 are engaged in the inner cavities of the first locking groove 22 and the second locking groove 32. At this time, the rotation direction of the limiting ring 5 is opposite to that of the bolt head 3. When the nut assembly 2 and the bolt body 1 need to be disconnected, the bolt head 3 needs to be rotated clockwise. During the rotation of the bolt head 3, the limiting ring 5 will rotate together. However, the limiting ring 5 is locked by the second locking groove 32 and the first locking groove 22 through the T-shaped sliders 51, thereby locking the bolt head 3.

[0030] By adding a limiting ring 5, when the bolt body 1 is threadedly connected to the nut assembly 2, it automatically supports the nut assembly 2 and the bolt head 3, preventing the bolt body 1 from directly rubbing against the nut assembly 2 during use, which would increase wear on the external threads of the bolt body 1 and reduce its service life. At the same time, by adding a T-shaped slider 51 and the first locking groove 22 and the second locking groove 32, when the limiting ring 5 self-locks between the bolt body 1 and the nut assembly 2, it automatically locks the position of the bolt body 1, thereby inhibiting the loosening of the bolt body 1 and improving the overall stability of the device.

[0031] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
