[0002] A nut is a screw cap, a part used to tighten together with a bolt or a screw rod for fastening. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, non-ferrous metals, etc. When the nut is installed on some equipment, such as an automobile or other equipment that is prone to vibration, an anti-loosening nut is often required to avoid the problem of nut loosening caused by vibration.

[0003] The existing anti-loosening nuts mostly achieve the anti-loosening function by adding a rubber pad or by using two nuts to cooperate with each other to clamp a clamping block. However, when using a rubber pad, it is easy to age over time, and the cooperation of the two nuts is still essentially a threaded connection. Therefore, there are problems with poor anti-loosening effects. Therefore, a reinforced clamping anti-loosening nut is needed to meet people's needs. Summary of the Utility Model

[0010] Preferably, the bottom of the rotating ring is fixedly connected to the top of the rotating hexagonal ring, and clamping holes are formed in the outer side walls of both the clamping nut and the fastening nut.

[0011] Beneficial effects

[0012] The utility model provides a tightened clamping anti-loosening nut. Compared with the prior art, the following

[0013] beneficial effects are achieved:

[0014] 1. For this tightened clamping anti-loosening nut, by setting an anti-loosening mechanism, the clamping nut is screwed onto the bolt. Then, use a wrench to rotate the clamping nut. The clamping nut rotates downward and moves. The clamping nut presses the clip, and the clip can clamp the bolt to prevent the fastening nut from loosening. After the clamping nut is tightened, pull the movable hexagonal ring downward to make the movable hexagonal ring move below the clamping nut. Then, rotate the movable hexagonal ring. The movable hexagonal ring drives the movable cylinder and the rotating cylinder to rotate. The rotation of the rotating cylinder deforms the clockwork spring. Then, put the movable hexagonal ring on the fastening nut. In this way, the elastic force of the clockwork spring tightens the clamping nut to prevent the clamping nut from rotating backward and rising, resulting in the loosening of the clip.

[0015] 2. For this tightened clamping anti-loosening nut, by setting a fixing mechanism, the movable hexagonal ring is sleeved on the fastening nut, and the clamping block is inserted into the lower clamping hole. When it is necessary to loosen the clamping nut, rotate the rotating hexagonal ring. The rotating hexagonal ring drives the rotating ring to rotate. The rotation of the rotating ring pulls the pulling rope, and the pulling rope pulls the clamping block to pull the movable hexagonal ring upward. Then, the clamping nut can be rotated backward for removal. Description of the drawings

Specific embodiments

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a reinforced clamping and anti-loosening nut, including a fastening nut 1.

An anti-loosening mechanism 6 is provided on the outer side of the clamping nut 5. The anti-loosening mechanism 6 includes a moving hexagonal ring 17, a moving cylinder 7, a rotating cylinder 8 and a fixing ring 9. A fixing mechanism 4 is provided inside the moving hexagonal ring 17. The fixing mechanism 4 includes a rotating hexagonal ring 10, a rotating ring 11, a plurality of clamping blocks 16, a plurality of springs 15 and a plurality of pulling ropes 13. The bottom of the fixing ring 9 is fixedly connected to the top of the clamping nut 5. The inner side wall of the rotating cylinder 8 is rotatably connected to the outer side wall of the fixing ring 9. The outer side wall of the rotating cylinder 8 is slidably connected to the inner side wall of the moving cylinder 7. A fixing groove 19 is formed in the outer side wall of the fixing ring 9. A clockwork spring 18 is fixed inside the fixing groove 19. The other end of the clockwork spring 18 is fixedly connected to the inner side wall of the rotating cylinder 8. The clamping nut 5 is screwed to a bolt. Use a wrench to rotate the clamping nut 5. The clamping nut 5 rotates downward and moves. The clamping nut 5 presses the clip 3. The clip 3 can clamp the bolt to prevent the fastening nut 1 from loosening. After the clamping nut 5 is tightened, pull the moving hexagonal ring 17 downward to make the moving hexagonal ring 17 move below the clamping nut 5. Then rotate the moving hexagonal ring 17. The moving hexagonal ring 17 drives the moving cylinder 7 and the rotating cylinder 8 to rotate. The rotation of the rotating cylinder 8 deforms the clockwork spring 18. Then put the moving hexagonal ring 17 on the fastening nut 1. In this way, the elastic force of the clockwork spring 18 tightens the clamping nut 5 to prevent the clamping nut 5 from reversing and rising, resulting in the loosening of the clip 3.

[0024] Furthermore, a plurality of storage holes 12 are formed in the inner side wall of the movable hexagonal ring 17. The spring 15 is fixed inside the storage hole 12. The clamping block 16 is located inside the storage hole 12. The clamping block 16 is fixedly connected to the spring 15. A rotating groove 14 is formed in the bottom of the movable hexagonal ring 17. The inner side wall of the rotating groove 14 is rotatably connected to the outer side wall of the rotating ring 11. One end of the clamping block 16 close to the spring 15 is fixedly connected to the pulling rope 13. The other end of the pulling rope 13 is fixedly connected to the inner side wall of the rotating ring 11. The bottom of the rotating ring 11 is fixedly connected to the top of the rotating hexagonal ring 10. Clamping holes 20 are formed in the outer side walls of both the clamping nut 5 and the fastening nut 1. The movable hexagonal ring 17 is sleeved on the fastening nut 1. The clamping block 16 is inserted into the lower clamping hole 20. When it is necessary to loosen the clamping nut 5, rotate the rotating hexagonal ring 10. The rotating hexagonal ring 10 drives the rotating ring 11 to rotate. The rotating ring 11 rotates to pull the pulling rope 13. The pulling rope 13 pulls the clamping block 16 to pull the movable hexagonal ring 17 upward. Then the clamping nut 5 can be reversed to be removed.

[0025] During operation, the clamping nut 5 is screwed onto the bolt. Use a wrench to rotate the clamping nut 5. The clamping nut 5 rotates downward and moves. The clamping nut 5 presses the clamping piece 3. The clamping piece 3 can clamp the bolt to prevent the fastening nut 1 from loosening. After the clamping nut 5 is tightened, pull the movable hexagonal ring 17 downward to move the movable hexagonal ring 17 below the clamping nut 5. Then rotate the movable hexagonal ring 17. The movable hexagonal ring 17 drives the movable cylinder 7 and the rotating cylinder 8 to rotate. The rotation of the rotating cylinder 8 deforms the clockwork spring 18. Then the movable hexagonal ring 17 is sleeved on the fastening nut 1. In this way, the elastic force of the clockwork spring 18 tightens the clamping nut 5 to prevent the clamping nut 5 from rotating reversely and rising, resulting in the loosening of the clamping piece 3.
