Description

Technical Field

[0001] This utility model relates to the field of round nut technology, specifically to a self-adaptive locking round nut structure. Background Technology

[0002] A round nut mainly consists of two parts: a stud and a cap. The stud is usually made of stainless steel or carbon steel, and its surface can be galvanized or phosphated to enhance rust resistance. The cap is made of copper or steel, and its surface is plated with nickel or chromium to increase aesthetics and rust resistance.

[0003] Conventional round nuts, due to their structural limitations, are prone to loosening under external forces such as vibration after being screwed together with structural components, leading to unnecessary detachment.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an adaptive locking round nut structure. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive locking round nut structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive locking round nut structure, comprising a nut body and a locking tooth groove, wherein the locking tooth groove is provided on the side edge of the nut body, and an assembly hole is obliquely provided on the front inclined surface of the nut body, and a limit pin is installed inside the assembly hole; a storage groove is provided on the rear vertical surface of the nut body, and a spring washer is provided inside the storage groove; one end of the limit pin is connected to a limit block.

[0007] Furthermore, the locking teeth are arranged in a circular array with the nut body as the center and four sets are provided, and the mounting holes are arranged in a circular array with the nut body as the center and four sets are provided, and the locking teeth and mounting holes are arranged in an alternating structure.

[0008] Furthermore, the surface of the limiting pin is provided with a threaded structure, and the end of the limiting pin away from the limiting block is provided with an internal hexagonal groove structure. Moreover, the surface of the limiting block away from the limiting pin and the inner diameter surface of the nut body are both provided with threaded structures of the same structure.

[0009] Furthermore, the inner wall surface of the assembly hole is provided with a thread structure that matches the surface structure of the limiting pin, and the assembly hole is opened at an angle of ° on the side of the nut body and penetrates the nut body.

[0010] Furthermore, the limiting pin and the limiting block are integrally formed, and the end surface of the limiting block away from the limiting pin protrudes from the surface of the inner diameter of the nut body where the threaded structure is provided.

[0011] Furthermore, the inner surface structure of the storage groove matches the outer surface structure of the spring washer, and the nut body is made of high-speed steel, while the spring washer and the nut body are made of the same material.

[0012] Furthermore, the surface of the nut body is coated with a protective coating, and the surface of the spring washer is coated with a wear-resistant coating.

[0013] Furthermore, the protective coating is made of polytetrafluoroethylene coating, and the wear-resistant coating is made of carbide coating material.

[0014] This utility model provides a self-adaptive locking round nut structure, which has the following beneficial effects:

[0015] 1. This utility model features an assembly hole obliquely opened on the front side of the nut body, with a limiting pin connected to a limiting block installed inside. Utilizing the threaded connection between the assembly hole and the limiting pin, the limiting pin is screwed along the inner wall of the assembly hole to a suitable position. This pushes one end of the limiting block against the inner diameter surface of the nut body, slightly protruding. Since the inner diameter surface of the nut body and the protruding end of the limiting block have threads of the same structure, the structural component screwed inside the nut body can be sequentially threaded to the nut body and the limiting block. Because one end of the limiting block protrudes to a certain extent from the inner diameter surface of the nut body, it can securely limit the structural component. After the structural component and the nut body are screwed into place, further screwing the limiting pin can rotate the limiting block, further engaging the threaded connection between the limiting block and the structural component. This maximizes the connection strength between the nut body and the structural component, preventing loosening due to external forces such as vibration.

[0016] 2. This utility model features a storage groove on the rear side of the nut body, with a spring washer installed inside. As the nut body is screwed in, when it reaches its final position, the spring washer located between the structural surface and the nut body is compressed. Due to the inherent structural characteristics of the spring washer, it exerts a counterforce on the structural surface and the nut body while being compressed. This causes the nut body, threaded onto the surface of the structural component, to be pushed in the opposite direction and engage more tightly with the threaded structure on the surface of the structural component. This maximizes the structural connection's stability and prevents unnecessary loosening. In addition, a protective coating and a wear-resistant coating are sprayed onto the surfaces of the nut body and the spring washer. The protective coating and the wear-resistant coating are made of polytetrafluoroethylene (PTFE) coating and carbide coating materials, respectively. Utilizing the material properties of PTFE coating and carbide coating materials, the nut body and the spring washer have good structural wear resistance. At the same time, the surface can effectively resist damage caused by wear, friction, and seizing forces. Meanwhile, the nut body and the spring washer themselves are made of high-speed steel, which gives them high hardness, high strength and high wear resistance, thereby enabling long-term repeated use and increasing the service life of the structural components.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, an adaptive locking round nut structure includes a nut body 1 and locking tooth grooves 2. Locking tooth grooves 2 are formed on the side edge of the nut body 1, and mounting holes 3 are obliquely formed on the front inclined surface of the nut body 1. A limit pin 4 is installed inside the mounting hole 3. A receiving groove 5 is formed on the rear vertical surface of the nut body 1, and a spring washer 6 is installed inside the receiving groove 5. One end of the limit pin 4 is connected to a limit block 7. The locking tooth grooves 2 are arranged in a circular array with the nut body 1 as the center, and four sets are formed. Similarly, four sets of mounting holes 3 are arranged in a circular array with the nut body 1 as the center. The locking tooth grooves 2 and mounting holes 3 are mutually... The two parts are arranged in an alternating structure. The surface of the limiting pin 4 is provided with a threaded structure, and the end of the limiting pin 4 away from the limiting block 7 is provided with an internal hexagonal groove structure. The surface of the limiting block 7 away from the limiting pin 4 and the inner diameter surface of the nut body 1 are both provided with the same threaded structure. The nut body 1 is provided with an obliquely provided assembly hole 3 on the front side, and the limiting pin 4 connected to the limiting block 7 is installed inside it. By using the threaded connection structure between the assembly hole 3 and the limiting pin 4, the limiting pin 4 is screwed along the inner wall surface of the assembly hole 3 to a suitable position. In this way, one end of the limiting block 7 is pushed to slightly protrude from the inner diameter surface of the nut body 1.

[0024] like Figures 1 to 4 As shown, the inner wall surface of the assembly hole 3 is provided with a threaded structure that matches the surface structure of the limiting pin 4. The assembly hole 3 is opened at a 45° angle on the side of the nut body 1 and penetrates the nut body 1. The limiting pin 4 and the limiting block 7 are set as an integral structure, and the surface of the limiting block 7 away from the limiting pin 4 protrudes from the inner diameter of the nut body 1 and is provided with a threaded structure. The inner surface structure of the receiving groove 5 matches the outer surface structure of the spring washer 6. The nut body 1 is made of high-speed steel, and the spring washer 6 and the nut body 1 are made of the same material. The surface of the nut body 1 is sprayed with a protective coating 8, and the surface of the spring washer 6 is sprayed with a protective coating 8. The nut body 1 is coated with a wear-resistant coating 9 and a protective coating 8 made of polytetrafluoroethylene (PTFE) coating. The wear-resistant coating 9 is made of carbide coating material. A storage groove 5 is provided on the rear side of the nut body 1, and a spring washer 6 is provided inside it. As the nut body 1 is screwed in, when it is screwed in place, the spring washer 6 located between the structural surface and the nut body 1 will be compressed by the structure. Due to the structural characteristics of the spring washer 6, while receiving structural compression, it will provide a reverse force on the structural surface and the nut body 1, so that the nut body 1, which is threaded to the surface of the structural component, will be pushed in the opposite direction and more tightly engaged with the thread structure on the surface of the structural component.

[0025] In summary, as Figures 1 to 4As shown, when using this adaptive locking round nut structure, firstly, the four sets of limiting pins 4 connected to the limiting blocks 7 are screwed into the assembly holes 3 opened on the surface of the nut body 1 in sequence using an Allen wrench. Then, the limiting blocks 7 with threaded structures on their surfaces are pushed against the inner diameter surface of the nut body 1 by screwing, and the threaded structure on one end of the limiting block 7 is aligned with the threaded structure on the inner diameter surface of the nut body 1.

[0026] Then, the spring washer 6 is embedded in the storage groove 5 on the rear side of the nut body 1, and the nut body 1 connected to the limit block 7 and the limit pin 4 is screwed together with the structural component until it is screwed to the appropriate position. At this time, the spring washer 6 between the nut body 1 and the structural surface will provide the opposite force while being squeezed by the structure due to its own structural characteristics, thereby pushing the nut body 1 so that the thread structure on the surface of the nut body 1 and the structural component are tightly engaged.

[0027] After the nut body 1 is tightened, the limiting pin 4 connected to the limiting block 7 can be adjusted by using an Allen wrench. This will not only press the limiting block 7 against the surface of the structural component, but also tightly engage the threaded structure at the connection between the two, thus ensuring the firmness of the connection between the nut body 1 and the structural component.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
