Description

Technical Field

[0001] The utility model belongs to the technical field of nuts, and in particular relates to a novel anti-loosening nut based on a conical elastic locking mechanism. Background Art

[0002] In many industries such as machinery, automobiles, aerospace, construction, and electronics, the fastening connection between bolts and nuts is the basis for various complex mechanical structures and systems. This connection method occupies a pivotal position in industrial production due to its simplicity, reliability, and easy maintenance. However, with the advancement of science and technology and the development of industry, the performance requirements for connectors are also increasing. In particular, when facing complex working conditions such as vibration, impact, and temperature changes, traditional nuts are often difficult to meet high-standard fastening requirements due to their inherent limitations.

[0003] During the tightening process, traditional nuts mainly rely on the friction between the threads to maintain the stability of the connection. However, this friction is easily weakened due to fatigue, wear or temperature changes when subjected to external dynamic loads, causing the nut to loosen. Once the nut is loose, it will not only affect the normal operation of the equipment, but may also cause safety accidents, resulting in huge economic losses and casualties. Therefore, how to effectively prevent the nut from loosening has become a technical problem that needs to be solved urgently.

[0004] In this context, the utility model proposes a new anti-loosening nut based on a conical elastic locking mechanism. The structure introduces a conical elastic metal part as a locking element, and utilizes its elastic deformation when subjected to pressure and its tight bite with the bolt thread groove to achieve a firm connection between the nut and the bolt. Compared with traditional nuts, the present application has higher anti-loosening performance, lower manufacturing cost and wider application range, and provides a new idea and method for solving the problem of nut loosening. Utility Model Content

[0005] The purpose of the utility model is to provide a novel anti-loosening nut based on a conical elastic locking mechanism to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel anti-loosening nut based on a conical elastic locking mechanism, comprising:

[0008] A connecting nut, one side of which is movably connected to a clamping nut, an elastic metal piece is movably connected between the clamping nut and the connecting nut, and the cross-section of the elastic metal piece is a conical structure.

[0009] Preferably, a support platform is provided inside the connecting nut, and the elastic metal part is fitted to one side of the support platform.

[0010] Preferably, a conical groove is provided inside the compression nut, and the elastic metal part is fitted with the inner wall of the conical groove.

[0011] Preferably, at least one of the connecting nut or the clamping nut is provided with a connecting thread groove.

[0012] Preferably, a tightening internal thread groove is provided inside the connecting nut on one side close to the elastic metal piece.

[0013] Preferably, a clamping external thread groove is provided on a side of the clamping nut close to the elastic metal piece.

[0014] Preferably, the clamping internal thread groove and the clamping external thread groove are threadably engaged with each other.

[0015] Preferably, the narrow end of the elastic metal piece faces the locking nut.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model realizes tight locking between the nut and the bolt by arranging an elastic metal part between the connecting nut and the clamping nut and utilizing the locking mechanism of the elastic metal part. This locking method not only overcomes the limitation of traditional nuts relying on friction to prevent loosening, but also can maintain the stability of the connection under harsh working conditions such as vibration and impact. The anti-loosening performance of the utility model is better than that of traditional nuts, and effectively reduces the risk of equipment failure and safety accidents caused by loose nuts. When in use, the connecting nut must first be screwed onto the outside of the bolt through the connecting thread groove, and then the elastic metal piece must be sleeved onto the outside of the bolt, and the elastic metal piece must be placed inside the connecting nut, and the wide end of the elastic metal piece must fit with the support platform, so that the support platform can support the elastic metal piece, and then the clamping nut must be sleeved onto the outside of the bolt, and the clamping nut must be screwed into the inside of the connecting nut by means of the cooperation of the clamping external thread groove and the clamping internal thread groove. During the tightening process, the conical groove must first fit with the elastic metal piece, and then the narrow end of the elastic metal piece must be continuously squeezed, causing the elastic metal piece to deform, and the narrow end of the elastic metal piece must shrink inward due to the force, so that the narrow end of the elastic metal piece must fit tightly with the thread of the bolt, and as the clamping nut is further tightened, the deformation of the elastic metal piece must be aggravated, and the thread locking force of the bolt must also be enhanced, thereby achieving a firm connection between the nut and the bolt, and effectively preventing loosening. The structure of the present application is relatively simple, and the manufacturing process is mature, and production can be completed without the use of special materials or special processes. This makes the manufacturing cost of the present application relatively low, which is conducive to popularization and application in a wide range of fields. At the same time, since the installation process of the present application is simple and quick, it also reduces the user's usage cost and time cost. The present application has a wide range of applicability. Whether it is mechanical equipment, building structure or electronic appliances, as long as it involves the fastening connection between bolts and nuts, the present application can be used for anti-loosening treatment. This wide applicability not only meets the needs of different industries for fastening connections, but also promotes technological progress and industrial upgrading in related fields. The present application shows significant beneficial effects in many aspects such as anti-loosening performance, manufacturing cost, and scope of application. The present application not only solves the problem of easy loosening of traditional nuts, but also promotes technological progress and industrial upgrading in related fields, and has broad market prospects and application value.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any sizes are only illustrative and not restrictive.

[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 5 As shown, a new anti-loosening nut based on a conical elastic locking mechanism comprises:

[0027] A connecting nut 1 is provided, one side of the connecting nut 1 is movably connected with a clamping nut 2, an elastic metal piece 3 is movably connected between the clamping nut 2 and the connecting nut 1, and the cross section of the elastic metal piece 3 is a frustum structure.

[0028] Specifically, a support platform 4 is provided inside the connecting nut 1, and the elastic metal part 3 is fitted with one side of the support platform 4. A conical groove 5 is provided inside the clamping nut 2, and the elastic metal part 3 is fitted with the inner wall of the conical groove 5. At least one of the connecting nut 1 or the clamping nut 2 is provided with a connecting thread groove 6. A clamping internal thread groove 7 is provided on the side of the connecting nut 1 close to the elastic metal part 3, and a clamping external thread groove 8 is provided on the side of the clamping nut 2 close to the elastic metal part 3. The clamping internal thread groove 7 and the clamping external thread groove 8 are threadedly engaged with each other, and the narrow end of the elastic metal part 3 faces the clamping nut 2.

[0029] It can be seen from the above that the connecting thread groove 6 opened on one side of the connecting nut 1 is used to connect with the bolt. At least one of the connecting nut 1 and the clamping nut 2 is provided with a connecting thread groove 6 for connecting with the bolt, or both are provided with a connecting thread groove 6, which can further improve the fastening performance of the nut. The support platform 4 is used to support the elastic metal part 3, and the conical groove 5 can be used to extrude the elastic metal part 3 to achieve the bite effect. The clamping internal thread groove 7 and the clamping external thread groove 8 are used to connect the clamping nut 2 and the connecting nut 1.

[0030] according to Figure 4 For example, during specific use, the connecting nut 1 needs to be tightened to the outside of the bolt through the connecting thread groove 6, and then the elastic metal part 3 is sleeved on the outside of the bolt, and the elastic metal part 3 is placed inside the connecting nut 1, and the wide end of the elastic metal part 3 is fitted with the support platform 4, so that the support platform 4 can support the elastic metal part 3, and then the clamping nut 2 is sleeved on the outside of the bolt, and the clamping nut 2 is screwed into the inside of the connecting nut 1 through the cooperation of the clamping external thread groove 8 and the clamping internal thread groove 7. During the tightening process, the tapered groove 5 will first fit with the elastic metal part 3, and then will continue to squeeze the narrow end of the elastic metal part 3, causing the elastic metal part 3 to deform, and its narrow end will shrink inward due to the force, so that the narrow end of the elastic metal part 3 is tightly engaged with the thread of the bolt. As the clamping nut 2 is further tightened, the deformation of the elastic metal part 3 is aggravated, and the thread locking force with the bolt is also enhanced, thereby achieving a firm connection between the nut and the bolt and effectively preventing loosening.

[0031] The utility model realizes a tight lock between the nut and the bolt by setting an elastic metal part 3 between the connecting nut 1 and the clamping nut 2, and utilizing the locking mechanism of the elastic metal part 3. This locking method not only overcomes the limitation of the traditional nut relying on friction to prevent loosening, but also can maintain the stability of the connection under harsh working conditions such as vibration and impact. The anti-loosening performance of the present application is better than that of the traditional nut, effectively reducing the risk of equipment failure and safety accidents caused by loose nuts. The structure of the present application is relatively simple, the manufacturing process is mature, and the production can be completed without the use of special materials or special processes. This makes the manufacturing cost of the present application relatively low, which is conducive to popularization and application in a wide range of fields. At the same time, since the installation process of the present application is simple and fast, it also reduces the user's use cost and time cost. The present application has a wide range of applicability. Whether it is mechanical equipment, building structure or electronic and electrical fields, as long as it involves the fastening connection between bolts and nuts, the present application can be used for anti-loosening treatment. This wide applicability not only meets the needs of different industries for fastening connections, but also promotes technological progress and industrial upgrading in related fields. The present application demonstrates significant beneficial effects in terms of anti-loosening performance, manufacturing cost, scope of application, etc. The present application not only solves the problem of easy loosening of traditional nuts, but also promotes technological progress and industrial upgrading in related fields, and has broad market prospects and application value.
