Description

Technical Field

[0001] The invention relates to the technical field of nut snap rings, and in particular to a shockproof locking nut snap ring. Background Art

[0002] In various mechanical equipment and structures, threaded connection is an indispensable part, and the nut ferrule is an important accessory in threaded connection. Its main role is to enhance the stability of the connection. Nut ferrules are usually made of metal or plastic materials. By increasing the friction between the threads, they effectively prevent the nut from loosening or falling off in harsh environments (such as high temperature and strong vibration conditions). When using, the ferrule needs to be put on the nut and screwed into the connector together to ensure that the ferrule can be tightly locked during rotation.

[0003] However, in a vibrating environment, traditional nut ferrules are sometimes still insufficient to completely prevent nuts from loosening. Some existing anti-loosening measures, such as spring washers or nylon embedded nuts, can alleviate the problem to a certain extent, but their effects are limited and their reliability is not high. Especially in critical machinery and structures, strict specifications must be followed for selection, design and installation to ensure that the nut ferrule can play its due tightening and protection role and ensure the reliability and safety of the connection.

[0004] When choosing the right nut ferrule, it is important to ensure that the ferrule size matches the nut, that it is properly seated and fits the connection surface during installation, and that overtightening is avoided to prevent damage. Nevertheless, there is still room for improvement in existing nut ferrule designs, especially in terms of performance under extreme conditions.

[0005] Therefore, there is a need for an efficient and reliable shockproof locking nut clamp that can improve stability and durability in a vibration environment and ensure that the safety and stability of the connection part can be maintained even under strong vibration. Summary of the invention

[0006] The purpose of the present invention is to solve the problems existing in the prior art and to propose a shockproof locking nut clamping ring.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a shockproof locking nut snap ring, comprising an outer ring, bend angle 1, bend angle 2, bend angle 3, bend angle 4, bend angle 5, bend angle 6, an inner ring, an end A, and an end B, characterized in that: it is formed by bending a steel material, including end A and end B at both ends, The outer ring is configured as a regular hexagonal structure; Furthermore, the inner ring is configured as a circular structure, the inner center of the outer ring and the inner ring are on the same vertical line; a gap is configured between the outer ring and the inner ring; Furthermore, the inner side of the outer ring is provided with bend 1, bend 2, bend 3, bend 4, bend 5 and bend 6 in clockwise direction. Furthermore, the three bends at the top of the outer ring are bent inwards to connect to the inner ring, and the five bends at the bottom of the outer ring are bent inwards to connect to the inner ring, and the degrees of the inward bends at the three and five bends are both set to 8°; Furthermore, after the outer ring is connected to the inner ring from the top, it is wound clockwise downwardly on the cylinder and connected to the bottom of the outer ring; Further, the end A is wound upward clockwise to form a regular hexagon, and the end B is wound downward counterclockwise to form a regular hexagon; Furthermore, the end A and the end B are arranged in the middle of the middle layer of the outer ring between the fourth bend and the fifth bend.

[0008] Compared with the prior art, the advantages and positive effects of the present invention are: 1) This clamp ring uses a unique hexagonal outer ring design and an internal circular inner ring structure, combined with a specific angle of bend (such as 85°) to bend inward to connect the inner and outer rings, ensuring that the connection can be highly stable even in a strong vibration environment. This geometric structure allows the force to be evenly distributed, reducing local stress concentration, thereby reducing the risk of loosening or falling off; 2) The gap between the outer ring and the inner ring provides an effective buffer area. When the external impact force acts on the outer ring, the gap can absorb and disperse the energy to avoid direct transmission to the inner ring and the bolts or shaft. In addition, the application of elastic materials or elastic connectors further enhances the shock absorption effect, enabling the snap ring to provide continuous protection under extreme conditions; 3) The overall design of the clamp takes into account the convenience of installation in practical applications. Ends A and B are located in the middle of the outer ring intermediate layer rather than on the outer surface, avoiding the impact of external direct force on the clamp body. At the same time, this design allows easy installation using standard tools without the need for special equipment or complex procedures, improving work efficiency and reducing installation costs; 4) Made of high-strength alloy steel and processed by precision cold bending process, it ensures that the retaining ring is not easily deformed or damaged during long-term use. The application of surface treatment technology also enhances corrosion resistance and prolongs service life. In addition, the design of the adaptive locking mechanism ensures that the retaining ring automatically adjusts to the optimal locking state during the tightening process, improving the reliability of the overall system.

[0011] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0012] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0013] like Figure 1-3 As shown, the present invention provides a shockproof locking nut snap ring, comprising an outer ring 1, a bend 11, a bend 2 12, a bend 3 13, a bend 4 14, a bend 5 15, a bend 6 16, an inner ring 2, an end A3, and an end B4, characterized in that: it is formed by bending a steel material, including the end A3 and the end B4 at both ends, The outer ring 1 is set to a regular hexagonal structure. The regular hexagon is the most stable polygonal structure. Each internal angle of the regular hexagon is 120 degrees, which enables it to evenly disperse the force when subjected to force. From the perspective of geometric structure, the six sides of the regular hexagon are equal in length. Such equal-length sides make the supporting force in all directions relatively balanced. When subjected to forces from different directions, the regular hexagon can distribute these forces more evenly to each side, thereby reducing the possibility of deformation or damage caused by excessive pressure on a certain side or a certain node, and further playing a role in shock prevention; The inner ring 2 is set to a circular structure, and the inner center of the outer ring 1 and the inner ring 2 are on the same vertical line; a gap is set between the outer ring 1 and the inner ring 2, so that a buffer space is created. When the outer ring 1 is impacted, it is avoided to directly affect the inner ring, thereby achieving a shock-absorbing effect to the greatest extent; The inner side of the outer ring 1 is provided with a bend 11, a bend 2 12, a bend 3 13, a bend 4 14, a bend 5 15 and a bend 6 16 in a clockwise direction. The bend angle 13 at the top of the outer ring 1 is bent inwardly to connect to the inner ring 2, and the bend angle 15 at the bottom of the outer ring 1 is bent inwardly to connect to the inner ring 2, and the degrees of the inward bends at the bend angles 13 and 15 are both set to 85°; After the outer ring 1 is connected to the inner ring 2 from the top, it is turned clockwise downward into a cylinder and connected to the bottom of the outer ring 1; The end A3 is wound upwards clockwise into a regular hexagon, and the end B4 is wound downwards counterclockwise into a regular hexagon; The end A3 and the end B4 are arranged in the middle of the middle layer of the outer ring 1 between the fourth bend 14 and the fifth bend 15, so that the ends are not on the surface to avoid bending due to force and affecting the overall use.

[0014] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
