[0002] A bolt is a mechanical part, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut and is used to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] The patent with publication number CN219432260U discloses an anti-loosening bolt, which belongs to the field of bolt technology. The anti-loosening bolt includes a bolt body and an anti-loosening mechanism, wherein the bolt body includes a screw, the upper end of the screw is provided with a first cavity, the inside of the screw is provided with a second cavity near the bottom of the first cavity, the inside of the second cavity is slidably connected to a limit block, a movable groove is provided in the limit block, a first spring is fixedly installed on one side of the inside of the second cavity, one end of the first spring is fixedly connected to one end of the limit block, the anti-loosening mechanism includes a gasket and a nut, the gasket is sleeved on the outside of the screw, a plurality of limit grooves are provided on the inside of the gasket, the limit grooves are clearance-matched with one end of the limit block, and the nut is threadedly connected to the bottom end of the screw.

[0004] In the above patent, a first anti-loosening spike is provided on the gasket, and a second anti-loosening spike is provided on the upper and lower ends of the nut to prevent the screw from loosening. Although it can have a certain anti-loosening effect, the anti-loosening effect of the anti-loosening spike is not high and still needs to be strengthened. Utility Model Content

[0005] The purpose of this application is to provide a new type of bolt that can solve the above problems.

[0006] The purpose of this application is to provide a new type of bolt, comprising:

[0007] Nut;

[0008] A screw rod, which is arranged on the nut;

[0009] The anti-loosening structure is provided on the nut to enhance the self-locking property of the bolt when it is tightened;

[0010] Among them, it also includes an adjusting structure, which is arranged on the screw rod and is used to adjust the length of the screw rod.

[0011] By setting a nut and a screw, the nut is the main part of the bolt, and the screw has threads. By setting an adjustment structure on the screw, the user can adjust the length of the screw according to actual needs, improve the flexibility of the bolt, and enable it to adapt to more different application scenarios. At the same time, an anti-loosening structure is also provided. Traditional bolts are prone to loosening when used for a long time or subjected to vibration, causing safety hazards. The bolt of the present application is provided with an anti-loosening structure on the nut, which effectively enhances the self-locking property of the bolt when locked, greatly improves its safety and stability, and ensures that the bolt can still maintain a tight fixed state when subjected to external force, thereby preventing loosening and falling off. By combining the nut, screw, anti-loosening structure and adjustment structure, a strong fixing ability and a wide range of applications are achieved.

[0012] Furthermore, the anti-loosening structure includes:

[0013] A first gasket, which is fixed to the bottom of the nut;

[0014] A first anti-slip tooth, arranged at the bottom of the first gasket;

[0015] The first anti-slip teeth include an inner gear ring and an outer gear ring, and the inner gear ring and the outer gear ring are arranged at intervals.

[0016] By fixing the first gasket at the bottom of the nut, the contact area between the bolt and the fixed object is increased, thereby improving the stability and load-bearing capacity of the bolt, and enabling the bolt to better disperse the force when subjected to external force, thereby reducing the risk of loosening and falling off. Among them, the first anti-skid teeth directly act on the contact surface between the bolt and the fixed object, increasing the friction between the two, thereby improving the self-locking property of the bolt. When the bolt is subjected to vibration or external force impact, the anti-skid teeth can effectively resist these forces and keep the bolt fixed. The first anti-skid teeth include an inner gear ring and an outer gear ring, which are spaced apart. This design enables the anti-skid teeth to form a multi-level locking structure on the contact surface, further enhancing the anti-loosening ability of the bolt. The spacing between the inner gear ring and the outer gear ring can also ensure that they can function effectively when subjected to external forces in different directions, thereby improving the overall stability and reliability of the bolt.

[0017] Further: the anti-loosening structure also includes:

[0018] Nuts;

[0019] A second gasket is arranged on the nut;

[0020] A second anti-slip tooth, arranged on the top of the second gasket;

[0021] Wherein, the second gasket and the nut are an integrated structure.

[0022] Through the design of the nut, the second gasket and the second anti-slip teeth, the stability and anti-loosening ability of the whole structure can be further improved. The nut realizes the tightening effect of the bolt by cooperating with the screw rod. At the same time, the nut and the second gasket work together to further enhance the anti-loosening effect. The second gasket is arranged on the nut and forms an integrated structure with the nut, so that the gasket and the nut can maintain a stable relative position during operation, avoiding loosening caused by vibration or external force. The existence of the second gasket not only increases the contact area between the nut and the fixed object and improves the stability, but also provides an installation basis for the second anti-slip teeth. At the same time, the second anti-slip teeth are arranged on the top of the second gasket. Similar to the first anti-slip teeth, they are both key components for increasing friction and self-locking. When the nut is tightened, the second anti-slip teeth will be in close contact with the fixed object to form a strong friction force to prevent the bolt from loosening, so that the bolt can maintain a more stable fixed state when subjected to vibration or external force impact.

[0023] Furthermore, a protective cover is provided on the nut, and an annular protrusion adapted to the protective cover is provided on the first gasket, and an inner wall of the annular protrusion contacts an outer wall of the protective cover.

[0024] By setting a protective cover on the first gasket, not only the key parts of the bolt are protected from erosion by the external environment, but also the overall stability and safety of the bolt are further improved. The protective cover is matched with the annular protrusion on the first gasket, which can ensure that the protective cover can fit tightly on the nut and is not easy to fall off. The inner wall of the annular protrusion contacts the outer wall of the protective cover, forming an effective sealing structure, which effectively prevents water, dust and other debris from entering the inside of the bolt, thereby avoiding the performance degradation of the bolt due to corrosion or contamination. In addition, when the bolt needs to be disassembled or replaced, the protective cover can be easily removed, which can make the maintenance of the bolt more convenient and extend the service life of the bolt.

[0025] Furthermore, the regulating structure includes:

[0026] An extension rod, wherein the extension rod is provided with an external thread;

[0027] A plug-in rod is arranged on the extension rod, and a limit plate is arranged on the plug-in rod;

[0028] The plug-in slot is arranged on the screw rod and is adapted to the plug-in rod, and an expansion slot communicating with the top of the plug-in slot is also arranged in the screw rod;

[0029] Among them, a limiting groove adapted by a limiting plate is also arranged on the plug-in slot, and at least two limiting plates are arranged.

[0030] By cooperating with the extension rod, the plug-in rod, the plug-in slot and the expansion slot, the length of the screw rod can be flexibly adjusted to meet the needs of different application scenarios. The external thread set on the extension rod can cooperate with a nut or other fasteners to fix and adjust the extension rod by rotation. The plug-in rod is set on the extension rod and is equipped with a limit plate. The presence of the limit plate can ensure that the plug-in rod remains stable when inserted into the plug-in slot to prevent it from shaking or falling off. The design of at least two limit plates further enhances the stability of the plug-in rod, making it less likely to deform or be damaged when subjected to external forces.

[0031] At the same time, the plug-in slot is adapted to the plug-in rod so that the plug-in rod can be smoothly inserted therein, and the expansion slot is connected to the top of the plug-in slot. After the plug-in rod is inserted into the expansion slot, the position of the plug-in rod can be limited by rotation, and a limit slot adapted to the limit plate is also provided on the plug-in slot. When the plug-in rod is inserted into the plug-in slot, the limit plate can be accurately embedded in the limit slot, thereby fixing the plug-in rod.

[0032] Furthermore, a rubber gasket is provided between the extension rod and the plug-in rod, and the rubber gasket is sleeved on the plug-in rod.

[0033] The rubber gasket has multiple beneficial effects. The rubber gasket can fill the gap between the screw and the extension rod, and the rubber gasket is squeezed during the cooperation between the limit plate and the extension slot. After the limit plate is fully cooperated with the extension slot, the squeezed rubber gasket is reset, and the elastic force acts on the screw and the extension rod, thereby ensuring that the limit plate and the extension slot are tightly fitted, so that the screw and the extension rod can be firmly connected together.

[0034] The beneficial effects of this application are:

[0035] 1. By setting an anti-loosening structure on the nut, the self-locking property of the bolt when locked is effectively enhanced, greatly improving its safety and stability, ensuring that the bolt can remain tightly fixed when subjected to external force, thereby preventing loosening and falling off. By combining the nut, screw, anti-loosening structure and adjustment structure, a strong fixing ability and a wide range of applications are achieved;

[0036] 2. Through the coordination of the extension rod, the plug rod, the plug slot and the expansion slot, the length of the screw rod can be flexibly adjusted to meet the needs of different application scenarios. The external thread on the extension rod can cooperate with the nut or other fasteners to fix and adjust the extension rod by rotation;

[0037] 3. The rubber gasket has multiple beneficial effects. The rubber gasket can fill the gap between the screw and the extension rod, and the rubber gasket is squeezed during the cooperation between the limit plate and the extension slot. After the limit plate is fully cooperated with the extension slot, the squeezed rubber gasket is reset, and the elastic force acts on the screw and the extension rod, thereby ensuring that the limit plate and the extension slot are tightly fitted, so that the screw and the extension rod can be firmly connected together.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] The following is a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0047] Embodiment 1:

[0048] like Figures 1 to 5 As shown, the embodiment of the present application provides a new type of bolt, including:

[0049] Nut 100;

[0050] A screw 200, which is disposed on the nut 100;

[0051] The anti-loosening structure 300 is provided on the nut 100 and is used to enhance the self-locking property of the bolt when it is tightened;

[0052] The adjusting structure 400 is also included. The adjusting structure 400 is arranged on the screw rod 200 and is used to adjust the length of the screw rod 200 .

[0053] By setting the nut 100 and the screw 200, the nut 100 is the main part of the bolt, and the screw 200 has threads. By setting the adjustment structure 400 on the screw 200, the user can adjust the length of the screw 200 according to actual needs, improve the flexibility of the bolt, and make it adaptable to more different application scenarios. At the same time, an anti-loosening structure 300 is also provided. When the traditional bolt is used for a long time or is subjected to vibration, it is easy to loosen, causing safety hazards. The bolt of the present application is provided with an anti-loosening structure 300 on the nut 100, which effectively enhances the self-locking property of the bolt when it is locked, greatly improves its safety and stability, and ensures that the bolt can still maintain a tight fixed state when subjected to external force, thereby preventing loosening and falling off. By combining the nut 100, the screw 200, the anti-loosening structure 300 and the adjustment structure 400, a strong fixing ability and a wide range of applications are achieved.

[0054] Embodiment 2:

[0055] An embodiment of the present application provides a new type of bolt. In addition to the above-mentioned technical features, the new type of bolt in the embodiment of the present application also includes the following technical features.

[0056] like Figures 1 to 5 As shown, the anti-loosening structure 300 includes:

[0057] A first gasket 310, the first gasket 310 is fixedly disposed at the bottom of the nut 100;

[0058] A first anti-slip tooth 320 is disposed at the bottom of the first gasket 310;

[0059] The first anti-slip teeth 320 include an inner gear ring 321 and an outer gear ring 322 , and the inner gear ring 321 and the outer gear ring 322 are arranged at intervals.

[0060] In the embodiment of the present application, by fixing the first gasket 310 at the bottom of the nut 100, the contact area between the bolt and the fixed object is increased, thereby improving the stability and bearing capacity of the bolt, and enabling the bolt to better disperse the force when subjected to external force, thereby reducing the risk of loosening and falling off. Among them, the first anti-skid teeth 320 directly act on the contact surface between the bolt and the fixed object, increasing the friction between the two, thereby improving the self-locking property of the bolt. When the bolt is subjected to vibration or external force impact, the anti-skid teeth can effectively resist these forces and keep the bolt fixed. The first anti-skid teeth 320 include an inner gear ring 321 and an outer gear ring 322, which are arranged at intervals. This design enables the anti-skid teeth to form a multi-level locking structure on the contact surface, further enhancing the anti-loosening ability of the bolt. The interval arrangement of the inner gear ring 321 and the outer gear ring 322 can also ensure that they can play an effective role when subjected to external forces in different directions, thereby improving the overall stability and reliability of the bolt.

[0061] Furthermore, the anti-loosening structure 300 further includes:

[0062] Nut 330;

[0063] A second gasket 340 is disposed on the nut 330;

[0064] A second anti-slip tooth 350 is disposed on the top of the second gasket 340;

[0065] The second gasket 340 and the nut 330 are an integral structure.

[0066] In some embodiments of the present application, the stability and anti-loosening ability of the entire structure can be further improved through the design of the nut 330, the second gasket 340 and the second anti-slip teeth 350. The nut 330 achieves the tightening effect on the bolt by cooperating with the screw rod 200. At the same time, the nut 330 and the second gasket 340 work together to further enhance the anti-loosening effect. The second gasket 340 is arranged on the nut 330 and forms an integral structure with the nut 330, so that the gasket and the nut 330 can maintain a stable relative position during operation, avoiding loosening caused by vibration or external force. The presence of the second gasket 340 not only increases the contact area between the nut 330 and the fixed object and improves the stability, but also provides an installation basis for the second anti-slip teeth 350. At the same time, the second anti-slip teeth 350 are arranged on the top of the second gasket 340. Similar to the first anti-slip teeth 320, they are key components for increasing friction and self-locking. When the nut 330 is tightened, the second anti-slip teeth 350 will be in close contact with the fixed object to form a strong friction force to prevent the bolt from loosening, so that the bolt can maintain a more stable fixed state when subjected to vibration or external force impact.

[0070] In the embodiment of the present application, by providing a protective cover 500 on the first gasket 310, not only the key parts of the bolt are protected from erosion by the external environment, but also the overall stability and safety of the bolt are further improved. The protective cover 500 is matched with the annular protrusion 510 on the first gasket 310, which can ensure that the protective cover 500 can fit tightly on the nut 100 and is not easy to fall off. The inner wall of the annular protrusion 510 is in contact with the outer wall of the protective cover 500, forming an effective sealing structure, which effectively prevents water, dust and other debris from entering the inside of the bolt, thereby avoiding the performance degradation of the bolt due to corrosion or contamination. In addition, when the bolt needs to be disassembled or replaced, the protective cover 500 can be easily removed, which can make the maintenance of the bolt more convenient and extend the service life of the bolt.

The plug rod 420 is provided on the extension rod 410 and is equipped with a limit plate 421. The existence of the limit plate 421 can ensure that the plug rod 420 remains stable when inserted into the plug slot 430 to prevent it from shaking or falling off. The design of at least two limit plates 421 further enhances the stability of the plug rod 420, making it less likely to deform or be damaged when subjected to external forces.
