[0002] There are many types of fasteners, the most common ones are bolts, screws, nuts, washers, etc. They are usually made of metal and have high strength and corrosion resistance. Different types of fasteners are suitable for different connection needs. For example, bolts are usually used to firmly connect two or more parts together, while screws are often used to fix one part to another.

[0003] However, in the prior art, when traditional fasteners are used to fasten objects, they may be subjected to vibration, impact or external force, which may cause slight displacement or deformation of the threaded connection part. Over time, such slight changes may gradually accumulate, causing the originally tightly connected parts to begin to loosen, resulting in a decrease in the fastening force, which in turn affects the stability and reliability of the entire structure. Therefore, we provide a fastener with an anti-slip structure. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a fastener with an anti-slip structure includes: an anti-slip mechanism 1, the anti-slip mechanism 1 includes a screw rod 11, a plurality of reinforcement holes 12 are arranged in an array on both sides of the outer surface of the screw rod 11, a nut 13 is arranged on the outer surface of the screw rod 11, and limiting grooves 14 are respectively arranged on both sides of the inner wall of the nut 13, and shifting blocks 15 are arranged on both sides of the outer surface of the nut 13. The inner surface of the nut 13 is threadedly connected with the outer surface of the screw rod 11, and the side of the shifting block 15 close to the nut 13 is in contact with the outer surface of the nut 13, and the two shifting blocks 15 are arranged on the side close to the nut 13. The outer surfaces of the two movable rods 16 are provided with springs 17, and the two movable rods 16 are away from the shifting blocks. A reinforcement block 18 is provided at one end of 15, the interior of the shift block 15 is movably connected with one end of the movable rod 16, the other end of the movable rod 16 passes through the inner ring of the spring 17 and is fixedly connected to the side of the reinforcement block 18 close to the shift block 15, one end of the spring 17 is fixedly connected to the side of the limiting groove 14 away from the reinforcement block 18, the other end of the spring 17 is fixedly connected to the side of the reinforcement block 18 close to the movable rod 16, the outer surface of the reinforcement block 18 is slidably connected to the inner wall of the limiting groove 14, the end of the reinforcement block 18 away from the spring 17 is clamped in the reinforcement hole 12, a first sealing ring 19 is provided on the top of the nut 13, the top of the nut 13 is butt-jointed with the first sealing ring 19, and a sealing mechanism 2 is provided on the top of the screw 11.

[0023] When the bolt 15 is in the locked position, the spring 17 is pressed against the locking nut 13 and the bolt 18 is engaged with the locking nut 13.

[0024] like Figure 1-Figure 4 As shown, the sealing mechanism 2 includes a connecting seat 21, a sealing groove 22 is provided at the bottom of the connecting seat 21, a second sealing ring 23 is connected to the inner wall of the sealing groove 22, a polygonal nut 24 is fixedly connected to the top of the connecting seat 21, and an anti-slip portion 25 is provided on the outer surface of the polygonal nut 24.

[0025] In this embodiment, the second sealing ring 23 can avoid direct contact between the object and the connecting seat 21, effectively reducing the extrusion force between the two, thereby reducing damage or deformation that may be caused by excessive extrusion. At the same time, the second sealing ring 23 can also reduce the wear between the two, and extend the service life of the object and the connecting seat 21. The anti-slip portion 25 can provide additional friction, making it more stable when tightening or loosening the nut, thereby improving the convenience and safety of operation.

[0026] The utility model provides a fastener with an anti-slip structure, and the specific working principle is as follows:

[0027] When the staff needs to use the fastener to fasten an object, they first need to move the shift block 15, and one side of the shift block 15 will be squeezed and contacted with one side of the nut 13. During this process, the movable rod 16 will be moved in the direction of the force. At the same time, the spring 17 will be squeezed and deformed due to the movement of the movable rod 16. Therefore, the reinforcement block 18 will be separated from the reinforcement hole 12. Next, the staff can rotate the screw rod 11 or the nut 13 to separate the two. In this way, the staff can use the screw rod 11 and the nut 13 to separate the two. Tighten the object. When the object is thoroughly tightened, the position of the reinforcement block 18 and the reinforcement hole 12 closest to it can be found. Then, by loosening the shift block 15, the spring 17 will lose the extrusion force and then restore the deformation. The generated rebound force will push the reinforcement block 18 to be clamped in the corresponding reinforcement hole 12, thereby achieving the anti-slip effect of the fastener. In addition, the first sealing ring 19 and the second sealing ring 23 can buffer part of the extrusion force between the nut 13, the connecting seat 21 and the object, reduce the friction and wear between them, and thus extend their service life.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
