Description

Technical Field

[0001] This utility model belongs to the technical field of anti-loosening nuts, specifically relating to the Guduojin anti-loosening nut. Background Technology

[0002] Locknuts are fasteners used to prevent bolts from loosening. They increase the friction, pressure, or elastic deformation between the threads through special structures or materials, resisting loosening caused by vibration and impact, and ensuring a stable connection. They are widely used in the automotive, aerospace, machinery manufacturing, and construction industries, and are especially suitable for bolted connections in vibration and impact environments, such as engine mounting and steel structure assembly.

[0003] In practical applications of mechanical equipment and engineering structures, lock nuts are key fasteners that prevent bolt connections from loosening. Their performance directly affects the reliability and safety of equipment operation. However, while current mainstream lock nuts (such as nylon insert nuts, metal lock nuts, or ordinary double nut structures) achieve basic anti-loosening functions by increasing thread friction, elastic deformation, or mechanical locking, they generally have the limitation of "passive vibration resistance." Their design principle mostly relies on static friction to maintain connection stability. During equipment operation, when subjected to continuous vibration, impact, or alternating loads, the friction between the threaded pairs will gradually decrease due to the accumulation of vibration energy, leading to fretting and slippage between the nut and bolt. Utility Model Content

[0004] The purpose of this invention is to provide a solid metal anti-loosening nut to solve the problem mentioned in the background art that the existing anti-loosening nut structure cannot achieve the effect of "tightening with vibration" and has poor anti-loosening effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Gudokin locknuts include:

[0007] Nut and washer;

[0008] Nut seat, which is fixedly connected to the top of the nut washer;

[0009] The threaded slot is formed inside the nut seat, the nut washer has a guide cavity inside, and the inner wall of the threaded slot has a threaded groove.

[0010] Preferably, the nut seat is a hexagonal nut.

[0011] Preferably, the nut seat is welded to the top of the nut washer, and the guide cavity is formed between the nut washer and the threaded hole groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a nut washer, nut seat, threaded groove, and guide cavity to create a vibration force transfer and guide structure between the guide cavity and the threaded groove. This structure forms the core of the anti-loosening nut, converting external vibration force into centripetal clamping force to achieve a "tighter with vibration" effect. In a vibrating environment, the force is guided to enhance the locking force between the threads, preventing loosening. The integrated anti-loosening thread structure eliminates the need for additional accessories (such as rubber rings or washers). A single nut can independently achieve the anti-loosening function and supports repeated installation and use, maintaining stable anti-loosening performance while simplifying the installation process.

[0017] In the diagram: 1. Nut washer; 2. Nut seat; 3. Threaded hole groove; 4. Drainage cavity. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1:

[0020] Please see Figures 1-3 As shown, the Gudokin locknut includes:

[0021] Nut and washer 1;

[0022] Nut seat 2, which is fixedly connected to the top of nut washer 1;

[0023] The threaded slot 3 is formed inside the nut seat 2. The nut washer 1 has a drainage cavity 4 inside. The inner side wall of the threaded slot 3 has a threaded groove. The nut seat 2 is a hexagonal nut. The nut seat 2 is welded to the top of the nut washer 1. The drainage cavity 4 is formed between the nut washer 1 and the threaded slot 3.

[0024] Specifically, the opening of the dredging cavity 4 forms a vibration force dredging structure, which can effectively transfer the position of the vibration force and transmit the vibration force at the bottom of the nut to the top of the nut, thereby converting the external vibration force into a centripetal clamping force.

[0025] As can be seen from the above, the structure between the guide cavity 4 and the threaded groove 3 forms a vibration force transfer and guide structure, which is the core structure of the anti-loosening nut. It can convert external vibration force into centripetal clamping force, achieving the effect of "the more it vibrates, the tighter it becomes". In the vibration environment, the locking force between the threads is enhanced by the force guidance to prevent loosening. The integrated anti-loosening thread structure does not require additional accessories.

[0026] Example 2:

[0027] A transverse vibration test was conducted on the anti-loosening nut to verify its residual axial force under vibration. The test conditions were: transverse vibration test frequency 12.5Hz, amplitude ±0.8mm, and grade 10.9 black matching bolts provided by the laboratory. The clamping force was 92.33kN for the first 150 cycles and 90.21kN for the first 1350 cycles; the clamping force was 91.66kN for the second 150 cycles and 88.99kN for the first 1350 cycles. Molybdenum disulfide lubricant was applied to the bolt threads and the nut bearing surface. The second test used the nut from the first test and a new bolt. Details are shown in the table below.

[0028]

[0029] According to the table above and the attached instruction manual Figure 3 It can be seen that the anti-loosening nut of this structure can effectively transfer the position of the vibration force, transmit the vibration force at the bottom of the nut to the top of the nut, form a centripetal clamping force, and achieve an excellent anti-loosening effect of "the more it vibrates, the tighter it becomes".
