Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to an anti-loosening bolt. Background Technique

[0002] A bolt is a mechanical part with a threaded structure, usually used to connect and fix two or more parts. A bolt generally consists of a threaded rod, a head, and a nut. The bolt connects two parts tightly by inserting the threaded rod into the pre-drilled parts and tightening the nut.

[0003] The head of the bolt usually has shapes such as hexagon, round head, square head, etc., to facilitate tightening the nut with a wrench or other tools. The nut is a part used to fix the bolt. By tightening the nut, the fastening force between the bolt and the part can be increased.

[0004] Bolts are generally used in occasions that require frequent disassembly and assembly, such as mechanical equipment, automobiles, construction and other fields. Bolts have strong connection force and reliable fixing performance and are widely used in various industries. At present, when the existing bolts are in use, the nut and the screw rod are fixedly connected. When the screw rod is damaged, the nut cannot be recycled, resulting in waste of resources. In addition, the length of the bolt is fixed and cannot be adjusted. At the same time, when the bolt is in use, it is easy to loosen and its stability needs to be improved. For this reason, we propose an anti-loosening bolt. Content of the Utility Model

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, A kind of anti-loosening bolt shown in the figure, including a cylinder 1. An installation mechanism is provided inside the cylinder 1. By setting the installation mechanism, the purpose of installing and disassembling the screw 3 is achieved. When the screw 3 is damaged, it is convenient to recycle the nut 4, reducing losses. And it is also convenient to adjust the length of the bolt, which is beneficial to the use of the bolt. The screw 3 is provided at the bottom end of the installation mechanism, and the nut 4 is provided at the top end of the cylinder 1. A cross slot 6 is opened at the top end of the nut 4. By setting the cross slot 6, it is convenient for a screwdriver to disassemble the bolt. A rivet 5 is slidably connected to the top end of the nut 4, and the rivet 5 penetrates through the bottom end of the nut 4. By setting the rivet 5, it is convenient to fix the bolt, which is beneficial to improving the stability of the bolt.

[0024] Among them, the installation mechanism includes a square slot 22, which is opened at the bottom end of the cylinder 1. By setting the square slot 22, it is convenient to receive the sliding of the square rod 21. The inner wall of the square slot 22 is slidably provided with a square rod 21. The screw 3 is fixedly installed at the bottom end of the square rod 21. Slots 24 are opened on both sides of the square rod 22. By setting the slots 24, it is convenient to receive one end of the plug block 25. A spring slot 26 is opened inside the square rod 21, and grooves 27 are opened on both sides of the square rod 21. The inner wall of the spring slot 26 is slidably provided with a plug block 25. One end of the plug block 25 penetrates through the square slot 22. By setting the plug block 25, it is convenient to insert it into the slot 24. The other end of the plug block 25 is provided with a pull rod 28. By setting the pull rod 28, it is convenient to pull the plug block 25 to slide along the inner wall of the spring slot 26. One end of the pull rod 28 penetrates through the groove 27. A spring 23 is provided on the inner wall of the spring slot 26, and one end of the spring 23 is fixedly connected to the plug block 25.

[0025] When using this anti-loosening bolt: According to the usage requirements, pull the two pull rods 28 on both sides. The pull rods 28 drive the plug blocks 25 to slide along the inner wall of the spring slot 26 until one end of the plug block 25 leaves the slot 24, then the fixing of the square rod 21 can be released. Then slide the square rod 21 along the square slot 22 until the bolt reaches the appropriate length and then release the pull rod 28. Under the action of the spring 23, the plug block 25 will be inserted into the slot 24 to complete the fixing of the square rod 21, which is beneficial to adjusting the length of the bolt and convenient for the use of the bolt.
