Embodiment 1

[0024] see figure 1 with figure 2 , a locknut, comprising a nut body 1, the nut body adopts a hexagonal nut, the end surface of the hexagonal nut is provided with a frictional surface 1-1 that increases the frictional force between the contact surface, and the frictional surface is preferably a ratchet Teeth 1-2 structure, the ratchets are helical teeth, and the ratchets are evenly distributed on the circumference.

Embodiment 2

[0026] see Figure 3 to Figure 7 A kind of anti-loosening nut, comprises nut body 1, and nut body adopts hexagonal nut, and one end of described hexagonal nut is provided with flange surface 2 integrated with hexagonal nut, is provided with friction surface 2-1 on flange surface 2 , the friction surface is preferably a ratchet 2-2 structure, the ratchets are helical teeth, and the ratchets are evenly distributed on the circumference.

[0027] see Figure 8 ,Using state: That is to say, ordinary hexagonal nuts are used, and a friction surface is added on the end surface of the hexagonal nut, so that there is a large friction force between the nut and the contact surface after installation and use, so that the connecting body is in a long-term vibration environment. Not easy to loose, to achieve the purpose of anti-loosening. In the disassembly type, as long as a wrench is used to overcome the bite force, it can be disassembled smoothly.

[0028] Therefore, the present invent...

Abstract

The invention relates to a locknut which comprises a nut body, and is characterized in that a friction surface for increasing the frictional force between the end surface of the nut body and a contact surface is arranged on the end surface of the nut body. Because the invention adopts the technical scheme that a friction surface is additionally arranged on the end surface of the common nut, a larger frictional force exists between the nut and the contact surface after installation and use, thus the nut can not loosen easily and achieves the purpose of locking when a connector is in a vibration environment for a long time. When the nut is removed, only a wrench is used for overcoming the snap-in force to remove the nut easily, so that the invention has the advantages of good locking effect, simple and reliable structure, no need of special tools for installation, wide applicable environment, no requirements for special technical parameters in design, and convenience in manufacture.

Description

technical field [0001] The invention belongs to the technical field of fastener manufacturing, in particular to a locknut. Background technique [0002] The traditional threaded connection is easy to loose when the connecting body is in a long-term vibration environment. For this reason, engineers and technicians have done a lot of work on thread loosening. , not only the number of parts increases, the processing is complicated, but also special tools are required for installation or disassembly, not only the structure is complex, the reusability is poor, and it is inconvenient to use. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a locknut with reliable structure, obvious anti-loosening effect, convenient use, and can be installed or disassembled without special tools. [0004] The technical scheme that the present invention takes for solving the technical problem existing in known tec...
