[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They are used in a broad range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, and hydraulics. Various types of fasteners can be found on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies. They are among the most widely used basic mechanical components, characterized by a large variety of types and specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to fasteners with existing standards as standard fasteners, or simply standard parts.

[0003] When bolts are installed, locking washers are used to limit the nut's position. After the nut moves to the appropriate position, multiple clips of the washer are bent and inserted into the nut's groove to limit the nut's position and prevent it from rotating to one side.

The two moving slots 31 are both opened inside the bolt 1. The two moving blocks 32 are slidably connected to the inside of the two moving slots 31 respectively. The moving sleeve 3 is disposed on the surface of the bolt 1. The limiting device 4 includes a limiting groove 41, a reset member 42, a limiting pin 43, a limiting hole 44, and a moving plate 45. The limiting groove 41 is opened inside the moving sleeve 33, the reset member 42 is disposed inside the limiting groove 41, the limiting pin 43 is slidably connected to the inside of the limiting groove 41, the limiting hole 44 is opened inside the nut 2, and one end of the moving plate 45 is rotatably connected to one end of the limiting pin 43.

[0019] The movable sleeve 33 is slidably connected to the surface of the bolt 1.

[0020] The nut 2 has multiple limiting holes 44 inside, which are used to limit the nut 2 after it is rotated to a suitable position on one side and the limiting pin 43 is inserted into the limiting hole 44.

[0021] The movable plate 45 is used to rotate to one side so that the limit pin 43 cannot be retracted to one side, thereby increasing the stability of the limit pin 43 when it is in the limit position.

[0022] The surfaces of both movable blocks 32 are fixedly connected to the surface of the inner wall of the movable sleeve 33.

[0023] Two movable blocks 22, together with two movable slots 21, are used to limit the movable sleeve 33, so that the movable sleeve 33 cannot rotate to one side.

[0024] One side of the limiting hole 44 is an opening, which is used for the limiting pin 43 to connect the moving plate 45 to move inside the limiting hole 44.

[0025] The reset element 42 is a spring, which is disposed inside the limiting groove 41 and located at one end of the limiting pin 43.

[0026] The reset element 42 can also be a spring sheet, which is used to push the limit pin 43 to move to one side inside the limit groove 41 and insert it into the limit hole 44 to limit the nut 2.

[0027] The working principle of the fastener with anti-reverse function provided by this utility model is as follows: In use, after inserting the two movable blocks 32 on the inner wall surface of the movable sleeve 33 into the inner wall of the two movable slots 31 respectively, and moving them to a suitable position to one side, the movable plate 45 is moved to one side, which drives the limiting pin 43 to move to one side inside the limiting slot 41, while pressing the reset piece 42.

[0028] After installing nut 2 into the appropriate position on bolt 1.

[0029] After releasing the moving plate 45, the reset piece 42 pushes the limit pin 43 to move to one side inside the limit groove 41, so that the limit pin 43 is inserted into the limit hole 44. Then, the moving plate 45 is rotated 90 degrees to one side.

[0030] Compared with related technologies, the fastener with anti-reverse function provided by this utility model has the following beneficial effects: This utility model provides a fastener with a backstop function. By using a moving device 3 in conjunction with a limiting device 4, the nut 2 is moved to a suitable position on the surface of the bolt 1 and then the nut 2 is limited, thereby preventing the nut 2 from rotating and loosening to one side. At the same time, it is convenient to separate the limiting device 4 from the nut and remove the nut 2.

[0033] The fixing element 5 is a rubber pad, and the top of the rubber pad is fixedly connected to the bottom of the movable plate 45.

[0034] One side of the rubber pad is an arc surface, which is used to move the rubber pad to the surface of the nut 2 when the moving plate 45 moves the rubber pad to one side.

[0035] The rubber pad is used to increase the friction between the moving plate 45 and the nut 2, while the elastic force of the rubber pad is squeezed to limit the movement between the moving plate 45 and the nut 2.

[0036] A rectangular block is fixedly connected to the top of the movable plate 45, and the rectangular block is used to facilitate the movement of the movable plate 45.

[0037] The rectangular block is used to increase the contact area between the movable plate 45 and the hand, thereby facilitating the rotation of the movable plate 45 to one side.

[0038] The working principle of the fastener with anti-reverse function provided by this utility model is as follows: In use, the movable plate 45 is rotated to one side to move it to a suitable position. After the surface of the fixing member 5 contacts the surface of the nut 2, the movable plate 45 is limited.
