A locking nut with an anti-rotation block kit

Abstract

This utility model discloses an anti-loosening nut with an anti-rotation block kit, including a mounting washer. The mounting washer is provided with a first anti-loosening component. By setting the first anti-loosening component and the second anti-loosening component, the problem of poor single anti-loosening effect in the prior art can be effectively solved. Specifically, the first anti-loosening component, through the cooperation of the adjusting block, the bidirectional screw, the moving block and the anti-loosening limit block, can precisely adjust the position of the anti-loosening limit block according to different working conditions, realize multi-point limiting, and effectively prevent the nut from rotating under complex working conditions such as vibration and temperature changes. At the same time, the second anti-loosening component further enhances the anti-loosening effect by utilizing the cooperation between the nut and the first self-tightening washer. In addition, the anti-rotation block is fixed to the mounting bracket by the second bolt and contacts the nut, restricting the rotational freedom of the nut. The two second self-tightening washers between the first bolt and the mounting washer enhance the limiting effect of the first bolt and prevent it from displacing during vibration.

Description

Technical Field

[0001] This utility model relates to the field of anti-loosening nuts, specifically to an anti-loosening nut with an anti-rotation block kit. Background Technology

[0002] A nut, also known as a bolt or screw, is a component screwed onto a bolt or screw to fasten it. It's an essential component in all manufacturing machinery. Based on the material, nuts are categorized into several types, including carbon steel, stainless steel, and non-ferrous metals (such as copper). A locknut is a component used to tightly connect mechanical equipment. It is connected to the bolt or screw of the same specification via internal threads. Locknuts offer superior vibration resistance. When tightened, the bolt's thread crest tightly enters the nut's 30° wedge-shaped slope and is locked in place. Furthermore, the normal force applied to the wedge-shaped slope forms a 60° angle with the bolt's axis, not a 30° angle. Therefore, the normal force generated when a locknut is tightened is much greater than that of a standard nut, providing significant anti-loosening and vibration resistance.

[0003] A search revealed a type of anti-loosening nut with an anti-rotation block kit in Chinese Patent Publication No. CN215333902U. By setting an anti-rotation block on the fixing part that is compatible with the nut model, the effect of the nut loosening can be avoided to the greatest extent, reducing the frequency of nut replacement to a certain extent and further reducing the wear and tear caused by nut loosening.

[0004] However, the aforementioned patent has certain shortcomings in practical use. While it can minimize the impact of loose nuts on performance, it only allows for a single application of anti-loosening treatment. This single-operation mode has significant drawbacks, resulting in less than ideal anti-loosening effects. For example, during the operation of large machinery, nuts may be subject to various complex factors, such as frequent vibrations, drastic temperature changes, and long-term axial or radial forces. Relying solely on a single anti-loosening treatment is insufficient to maintain the nut's tightness continuously and effectively, potentially leading to nut loosening during equipment operation. This could affect the stability and reliability of the equipment, posing a potential risk to the safe operation of the machinery.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an anti-loosening nut with an anti-rotation block kit to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A locking nut with an anti-rotation block kit includes a mounting washer, a first locking component on the mounting washer, a second locking component on the first locking component, and a first bolt on the mounting washer. One end of the first bolt has an adjustment groove, and an adjustment block is movably connected to the inner wall of the adjustment groove.

[0009] Furthermore, to better ensure the adjustment effect, a bidirectional screw is provided at one end of the adjustment block, and one end of the bidirectional screw is connected to the inner wall of the adjustment groove. Two moving blocks are threadedly connected to the bidirectional screw.

[0010] Furthermore, in order to better ensure the anti-loosening and limiting effect, the two sides of the movable block are movably connected to the adjusting plate, and one end of the adjusting plate is movably connected to the anti-loosening and limiting block. The first bolt is symmetrically provided with limiting grooves, and the limiting grooves are connected to the adjusting grooves.

[0011] Furthermore, in order to better ensure the anti-loosening effect of the nut, the second anti-loosening component includes a nut, which is threadedly connected to the first bolt, and the anti-loosening limiting block contacts the inner wall of the nut through a limiting groove, and two first self-tightening washers are provided directly below the nut.

[0012] Furthermore, in order to better ensure the anti-loosening and limiting effect of the nut, one end of each of the two first self-tightening washers is in contact with the nut and one end of the mounting washer, respectively. One of the first self-tightening washers is symmetrically provided with a mounting bracket, and a second bolt is threadedly connected to the mounting bracket. One end of the second bolt is provided with an anti-rotation block through a bearing, and the anti-rotation block is in contact with the nut.

[0013] Furthermore, in order to better ensure the limiting effect of the first bolt, two second self-tightening washers are provided between the first bolt and the mounting washer, and one end of the two second self-tightening washers is in contact with one end of the mounting washer and one end of the first bolt, respectively.

[0014] The beneficial effects of this utility model are as follows: By setting a first anti-loosening component and a second anti-loosening component, the problem of poor single-time anti-loosening effect in the prior art can be effectively solved. Specifically, the first anti-loosening component, through the cooperation of an adjusting block, a bidirectional screw, a moving block, and an anti-loosening limiting block, can precisely adjust the position of the anti-loosening limiting block according to different working conditions, realize multi-point limiting, and effectively prevent the nut from rotating under complex working conditions such as vibration and temperature changes. At the same time, the second anti-loosening component utilizes the cooperation between the nut and the first self-tightening washer to further enhance the anti-loosening effect. When the equipment is running, the two ends of the first self-tightening washer contact the nut and the mounting washer respectively, generating axial self-tightening force to prevent the nut from axially loosening. In addition, the anti-rotation block is fixed to the mounting bracket by the second bolt and contacts the nut, restricting the rotational freedom of the nut. The two second self-tightening washers between the first bolt and the mounting washer enhance the limiting effect of the first bolt and prevent it from displacing during vibration. This multiple anti-loosening can significantly improve the tightness and reliability of the nut under complex working conditions and reduce the safety hazards and maintenance costs caused by nut loosening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] like Figures 1-7 As shown, a locking nut with an anti-rotation block kit according to an embodiment of the present utility model includes a mounting washer 1, a first locking component 2 is provided on the mounting washer 1, and a second locking component 3 is provided on the first locking component 2.

[0028] The first anti-loosening component 2 includes a first bolt 201 mounted on the mounting gasket 1. One end of the first bolt 201 has an adjustment groove 4. An adjustment block 202 is movably connected to the inner wall of the adjustment groove 4. One end of the adjustment block 202 is provided with a bidirectional screw 203. The bidirectional screw 203 has a conventional structure, so it will not be described in detail. One end of the bidirectional screw 203 is connected to the inner wall of the adjustment groove 4. Two moving blocks 204 are threadedly connected to the bidirectional screw 203. Adjustment plates 207 are movably connected to both sides of the moving blocks 204 through a rotating shaft. One end of the adjustment plate 207 is movably connected to an anti-loosening limit block 205 through a rotating shaft. Limiting grooves 206 are symmetrically opened on the first bolt 201. The limiting grooves 206 are connected to the adjustment groove 4.

[0029] Example 2:

[0030] like Figures 1-7As shown, according to an embodiment of the present invention, a locking nut with an anti-rotation block kit is provided. The second locking component 3 includes a nut 301, which is threadedly connected to a first bolt 201. The locking limit block 205 contacts the inner wall of the nut 301 through a limit groove 206. Two first self-tightening washers 302 are provided directly below the nut 301. One end of the two first self-tightening washers 302 contacts the nut 301 and one end of the mounting washer 1, respectively. One of the first self-tightening washers 302 is symmetrically provided with a mounting bracket 303. A second bolt 304 is threadedly connected to the mounting bracket 303. One end of the second bolt 304 is provided with an anti-rotation block 305 through a bearing. The anti-rotation block 305 contacts and is compatible with the nut 301. Two second self-tightening washers 306 are provided between the first bolt 201 and the mounting washer 1. One end of the two second self-tightening washers 306 contacts the mounting washer 1 and one end of the first bolt 201, respectively.

[0031] One end of each of the two first self-tightening washers 302 and the two second self-tightening washers 306 is provided with a serrated structure, and the serrated structures mesh with each other. The other end of each of the two first self-tightening washers 302 and the two second self-tightening washers 306 is provided with a toothed structure. The specific structure is a conventional structure, and the principle is a conventional principle, so it will not be described in detail.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In summary, by means of the above-mentioned technical solution of this utility model, when the mounting gasket 1 is affected by complex working conditions such as vibration, the adjusting block 202 moves within the adjusting groove 4, driving the bidirectional screw 203 to rotate, causing the two moving blocks 204 to move relative to or away from each other along the bidirectional screw 203. The movement of the moving blocks 204 drives the adjusting plate 207, which in turn drives the anti-loosening limiting block 205 to move within the limiting groove 206. The anti-loosening limiting block 205 contacts the inner wall of the nut 301, effectively preventing the rotation of the nut 301 through multi-point limiting. The first anti-loosening barrier is activated. At the same time, the second anti-loosening component 3 begins to function. The nut 301 is threaded onto the first bolt 201. When the nut 301 is subjected to axial force, the two first self-tightening washers 302 contact the nut 301 and the mounting washer 1 respectively, generating axial self-tightening force to prevent the nut 301 from axially loosening. In addition, the second bolt 304 on the mounting bracket 303 is connected to the anti-rotation block 305 through the bearing. The anti-rotation block 305 contacts the nut 301, further restricting the rotational freedom of the nut 301. This is the second anti-loosening barrier.

[0034] Finally, the two second self-tightening washers 306 between the first bolt 201 and the mounting washer 1 engage with each other, enhancing the limiting effect of the first bolt 201 and preventing it from shifting during vibration. This is the third anti-loosening barrier. Through the coordinated action of these three anti-loosening barriers, the tightness and reliability of the nut 301 under complex working conditions are significantly improved, reducing the safety hazards and maintenance costs caused by the loosening of the nut 301.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
