Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a novel anti-loosening nut. Background Art

[0002] A nut is a cap that is screwed together with a bolt or screw to fasten. It is an essential component for all manufacturing machinery. Depending on the material, it is divided into several major types, such as carbon steel, stainless steel, and non-ferrous metals. The nut is a part that tightly connects mechanical equipment. Nuts and bolts of the same specifications can be connected together through the inner thread.

[0003] When fixing the splint, nuts are needed. However, the nuts in the existing technology are prone to thread slippage due to long time and vibration during use, causing the nuts to fall off. This not only reduces the fixing effect of the nuts, but also increases the operating risks of the mechanical equipment. Therefore, a new type of anti-loosening nut is urgently needed to overcome the above defects. Utility Model Content

[0004] The purpose of the utility model is to provide a novel anti-loosening nut, which has the advantages of good anti-falling effect and easy fixation, so as to solve the problems raised in the above background technology.

[0006] Furthermore, the clamping grooves are evenly arranged on the surface of the nut body, and the bottom of the positioning block is fixedly connected to the top of the first clamping plate.

[0007] Furthermore, the limiting groove is provided inside the positioning block, and the positioning rod slides in the inner cavity of the limiting groove.

[0008] Furthermore, the right side of the positioning rod is fixedly connected to the left side of the positioning plate, and the thread groove is opened at the top of the limiting groove.

[0009] Furthermore, the threaded rack is rotated inside the threaded groove through the thread, and the spring is fixedly installed on the left side of the positioning plate.

[0010] Furthermore, the left side of the spring is fixedly connected to the right side of the positioning block, and the number of the springs is two.

[0011] Furthermore, the inner diameter of the second wedge-shaped washer is the same as the inner diameter of the first wedge-shaped washer, and the through grooves are both opened inside the first clamping plate and the second clamping plate.

[0012] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:

[0013] The present invention can fix the connection between the first clamping plate and the second clamping plate by arranging a nut anti-loosening component and a bolt body, and prevent the nut from being displaced at the same time, and can reinforce the nut anti-loosening component by arranging a positioning component. When in use, the bolt body is first passed through the through groove to the top of the first clamping plate, and then the second wedge washer, the first wedge washer and the nut body are sleeved on the surface of the bolt body, and the nut body is rotated by means of a wrench, so that the nut body is threadedly fixed with the surface of the bolt body under the action of the force. Then, the positioning plate is loosened, and the positioning plate drives the positioning rod to move to the left side under the action of the spring, and penetrates into the interior of the nut body through the clamping groove, thereby fixing the nut body. Finally, the threaded rack is rotated, and the bottom of the threaded rack limits the top of the positioning rod, which has the advantages of good anti-loosening effect and convenient fixing. It solves the problem that the nut of the prior art is prone to slipping due to long time and vibration when in use, causing the nut to fall off, which not only reduces the fixing effect of the nut, but also increases the operation risk of mechanical equipment.

[0022] More specifically, the nut anti-loosening assembly 3 is reinforced by setting a positioning assembly 2. When in use, the bolt body 4 is first passed through the through slot 5 to the top of the first clamping plate 11, and then the second wedge washer 34, the first wedge washer 33 and the nut body 31 are sleeved on the surface of the bolt body 4, and the nut body 31 is rotated with the help of a wrench. Under the action of force, the nut body 31 is threadedly fixed to the surface of the bolt body 4, and then the positioning plate 22 is loosened. Under the action of the spring 24, the positioning plate 22 drives the positioning rod 23 to move to the left and passes through the slot 32 to the inside of the nut body 31, thereby fixing the nut body 31, and finally the threaded rack 25 is rotated. The bottom of the threaded rack 25 limits the top of the positioning rod 23, which has the advantages of good anti-falling effect and easy fixation.

[0023] In some embodiments, the slots 32 are evenly arranged on the surface of the nut body 31, and the bottom of the positioning block 21 is fixedly connected to the top of the first clamping plate 11. More specifically, by setting the slots 32, the positioning rod 23 can pass through the slots 32 to the interior of the nut body 31, thereby fixing the nut body 31.

[0024] In some embodiments, the limiting groove 27 is opened inside the positioning block 21, and the positioning rod 23 slides in the inner cavity of the limiting groove 27. More specifically, the positioning rod 23 is limited by setting the limiting groove 27 to prevent the positioning rod 23 from shaking during the movement.

[0025] In some embodiments, the right side of the positioning rod 23 is fixedly connected to the left side of the positioning plate 22, and the threaded groove 26 is opened at the top of the limiting groove 27. More specifically, the positioning rod 23 is connected by setting the positioning plate 22, and the threaded rack 25 is limited by setting the threaded groove 26.

[0026] In some embodiments, the threaded rack 25 is rotated inside the threaded groove 26 through threads, and the spring 24 is fixedly installed on the left side of the positioning plate 22. More specifically, the positioning rod 23 is fixed by setting the threaded rack 25.

[0027] In some embodiments, the left side of the spring 24 is fixedly connected to the right side of the positioning block 21, and there are two springs 24. More specifically, the positioning plate 22 is reset by setting the spring 24, thereby indirectly fixing the position of the positioning rod 23.

[0028] In some embodiments, the inner diameter of the second wedge-shaped washer 34 is the same as the inner diameter of the first wedge-shaped washer 33, and the through grooves 5 are both opened inside the first clamping plate 11 and the second clamping plate 12. More specifically, by setting the first wedge-shaped washer 33 and the second wedge-shaped washer 34, a special sealing gasket is used to fix the bolt body 4 and the nut body 31. It is semicircular and has a conical slope on one side, which can increase the fastening force of the bolt body 4 and the nut body 31 and prevent the bolt body 4 and the nut body 31 from falling off during vibration.

[0029] Working principle:

[0030] Step 1: When using, first pass the bolt body 4 through the through slot 5 to the top of the first clamping plate 11, then put the second wedge washer 34, the first wedge washer 33 and the nut body 31 on the surface of the bolt body 4, and use a wrench to rotate the nut body 31. Under the action of the force, the nut body 31 is threadedly fixed to the surface of the bolt body 4. Then, loosen the positioning plate 22. Under the action of the spring 24, the positioning plate 22 drives the positioning rod 23 to move to the left and penetrate into the interior of the nut body 31 through the slot 32, thereby fixing the nut body 31. Finally, rotate the threaded rack 25, and the bottom of the threaded rack 25 limits the top of the positioning rod 23.

[0031] Step 2: A special sealing gasket is provided to fix the bolt body 4 and the nut body 31 by setting a first wedge-shaped washer 33 and a second wedge-shaped washer 34. The washer is semicircular and has a conical slope on one side, which can increase the fastening force of the bolt body 4 and the nut body 31 and prevent the bolt body 4 and the nut body 31 from falling off during vibration. It has the advantages of good anti-falling effect and easy fixation.
