Description

Technical Field

[0001] This application relates to the field of nylon nut technology, specifically nylon anti-loosening nuts. Background Technology

[0002] Nylon nuts are a branch of the broader category of nuts. They are used in conjunction with bolts to join two or more components together. Nylon nuts possess excellent insulation properties, are non-magnetic, heat-insulating, and lightweight. Some materials also offer high temperature resistance, high strength, and corrosion resistance. They can be used with both plastic and metal screws, and some models feature a locking function. They are widely used in various industrial fields.

[0003] Traditional nylon lock nuts have an integrated design of nylon ring and nut. After frequent disassembly and assembly, the nylon ring will wear, age, or deform and fail, and the entire nut will need to be replaced, which will increase the cost of use. In order to solve the problem of the inconvenience of replacing nylon ring, nylon lock nuts were proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a nylon anti-loosening nut. By replacing the nylon ring separately, the nut body can continue to be used, reducing waste of parts and resources.

[0005] To achieve the above objectives, this application provides the following technical solution: a nylon anti-loosening nut, comprising a nut body, a snap-fit ​​mechanism, and a nylon ring. The nylon ring is snapped into the interior of the nut body by the snap-fit ​​mechanism. The snap-fit ​​mechanism includes a positioning ring fixedly connected to the upper surface of the nut body. Four locking rods are slidably sleeved on the inner wall of the positioning ring. A circular plate is welded to the outer surface of each locking rod. A limit spring is fixedly connected to the outer surface of each circular plate. The four limit springs are fixedly connected to the outer surface of the positioning ring. Locking holes corresponding to the four locking rods are opened on the outer surface of the nylon ring. A reserved groove is opened at the top of the inner wall of the nut body. A first thread is opened on the inner wall of the nut body. A second thread corresponding to the first thread is opened on the inner wall of the nylon ring.

[0006] The above solution utilizes a snap-fit ​​mechanism that allows for easy installation and removal of the nylon ring from the nut body. This enables quick replacement of the nylon ring when it fails, allowing the nut body to continue operating. Compared to replacing the entire nut, only the small nylon ring needs to be replaced, significantly reducing material consumption and minimizing waste of parts and resources. Furthermore, the second threaded section allows the nut body to engage with the screw thread during tightening, creating a mechanical locking effect. This increased friction, combined with the radial clamping force applied to the screw by the deformed nylon ring, achieves a double locking effect, effectively preventing loosening and enhancing practicality.

[0007] Furthermore, each of the circular plates has a paddle fixedly connected to its outer surface, and each paddle has an anti-slip coating on its outer surface.

[0008] The above method can increase the contact area of ​​the circular plate surface, thus making it easier to pull the circular plate.

[0009] Furthermore, the inner bottom wall of the reserved groove is provided with uniformly distributed first grooves.

[0010] The above solution increases the friction of the bottom wall of the reserved groove, thereby optimizing the stability of the nylon ring snapping into the nut body.

[0011] Furthermore, the inner bottom wall of the reserved groove is provided with a guide groove, and the inner bottom wall of the guide groove is provided with a uniformly distributed second groove.

[0012] The above solution can increase the friction of the bottom wall of the guide groove, thereby further improving the stability of the nylon ring snap-fit.

[0013] Furthermore, a guide ring is fixedly connected to the bottom surface of the nylon ring, and the size of the guide ring is adapted to the size of the guide groove.

[0014] The above method allows the nylon ring to be installed more stably inside the nut body.

[0015] Furthermore, the height of the nylon ring is greater than the sum of the heights of the positioning ring and the reserved groove.

[0016] The above method can create a high-friction zone, preventing the nut body from loosening.

[0017] Furthermore, a T-shaped groove is formed on the upper surface of the positioning ring, and a T-shaped block corresponding to the T-shaped groove is fixedly connected to the outer surface of the nylon ring.

[0018] The above method can limit the installation position of the nylon ring, making the connection between the second thread and the first thread more precise, thus ensuring smooth installation of the screw.

[0019] Furthermore, a rectangular groove is formed on the upper surface of the positioning ring, and a rectangular block corresponding to the rectangular groove is fixedly connected to the outer surface of the nylon ring.

[0020] The above method can further limit the installation position of the nylon ring, and the stability of the nylon ring can be optimized by combining the T-groove and T-block.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This nylon anti-loosening nut features a convenient snap-fit ​​mechanism that allows for easy removal and installation of the internal nylon ring. When the nylon ring fails, only the ring needs to be replaced, rather than the entire nut. This design significantly reduces material consumption, waste parts, and resource waste. The nut has a second thread inside that engages with the screw thread during tightening, creating a mechanical locking effect and increasing friction. When the nylon ring deforms, it applies a radial clamping force to the screw, achieving a double locking effect and effectively preventing the nut from loosening, making it more practical and reliable.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 3The nylon anti-loosening nut in this embodiment includes a nut body 1, a snap-fit ​​mechanism 2, and a nylon ring 3. The nylon ring 3 is snapped into the inside of the nut body 1 by the snap-fit ​​mechanism 2. The snap-fit ​​mechanism 2 includes a positioning ring 201 fixedly connected to the upper surface of the nut body 1. Four locking rods 202 are slidably sleeved on the inner wall of the positioning ring 201. A circular plate 203 is welded to the outer surface of each locking rod 202. A lever 204 is fixedly connected to the outer surface of each circular plate 203. The outer surface of each lever 204 is coated with an anti-slip layer. By setting the lever 204, the contact area of ​​the circular plate 203 can be increased, thereby facilitating the pulling of the circular plate 203. A limit spring 205 is fixedly connected to the outer surface of each circular plate 203. All four limit springs 205 are fixedly connected to the outer surface of the positioning ring 201. When the locking rod 202 is pulled outward, The limiting spring 205 can deform to generate elastic force. When the pulled locking rod 202 is released, the locking rod 202 will reset with the elastic force generated by the deformation of the limiting spring 205. The outer surface of the nylon ring 3 is provided with locking holes 206 corresponding to the four locking rods 202. When the four locking rods 202 are respectively inserted into the corresponding locking holes 206, the nylon ring 3 can be limited. When the four locking rods 202 are respectively removed from the corresponding locking holes 206, the limitation on the nylon ring 3 can be released. The top of the inner wall of the nut body 1 is provided with a reserved groove 207. The reserved groove 207 facilitates the installation and removal of the nylon ring 3. The height of the nylon ring 3 is greater than the sum of the heights of the positioning ring 201 and the reserved groove 207, which can form a high friction zone to prevent the nut body 1 from loosening. It also facilitates the installation and removal of the nylon ring 3.

[0031] Please see Figure 1 , Figure 3 and Figure 4 The inner bottom wall of the reserved groove 207 is provided with a uniformly distributed first groove 208. By providing the first groove 208, the friction of the inner bottom wall of the reserved groove 207 can be increased, thereby optimizing the stability of the nylon ring 3 being snapped into the nut body 1. The inner bottom wall of the reserved groove 207 is provided with a guide groove 209. The inner bottom wall of the guide groove 209 is provided with a uniformly distributed second groove 210. By providing the second groove 210, the friction of the inner bottom wall of the guide groove 209 can be increased, further improving the stability of the nylon ring 3 being snapped into the nut body 1 and reducing the probability of the nylon ring 3 becoming loose. A guide ring 211 is fixedly connected to the bottom surface of the nylon ring 3. The size of the guide ring 211 is adapted to the size of the guide groove 209. By setting the guide ring 211, the nylon ring 3 can be guided to be installed inside the nut body 1, simplifying the installation process of the nylon ring 3.

[0032] Please see Figure 2 , Figure 3 and Figure 4The inner wall of the nut body 1 has a first thread 4, and the inner wall of the nylon ring 3 has a second thread 5 corresponding to the first thread 4. The second thread 5 allows the nylon ring 3 to be tightly locked onto the outer surface of the screw. After the second thread 5 on the inner wall of the nylon ring 3 precisely engages with the screw thread, a mechanical interlocking structure is formed. This engagement restricts the axial and rotational relative movement between the screw and the nut body 1. Even under strong vibration or impact, the mechanical locking effect remains stable. The upper surface of the positioning ring 201 has a T-groove 6, and the outer surface of the nylon ring 3... A T-shaped block 7 corresponding to the T-shaped groove 6 is fixedly connected. The T-shaped groove 6 and the T-shaped block 7 can limit the installation position of the nylon ring 3, so that the second thread 5 and the first thread 4 are more accurately connected, and the screw is installed smoothly. A rectangular groove 8 is opened on the upper surface of the positioning ring 201. A rectangular block 9 corresponding to the rectangular groove 8 is fixedly connected to the outer surface of the nylon ring 3. The installation position of the nylon ring 3 can be further limited by setting the rectangular groove 8 and the rectangular block 9. In addition, the stability of the nylon ring 3 can be optimized in conjunction with the T-shaped groove 6 and the T-shaped block 7.

[0033] In this embodiment, the snap-fit ​​mechanism 2 allows for easy assembly and disassembly of the nylon ring 3 within the nut body 1. This enables quick replacement of the nylon ring 3 when it fails, allowing the nut body 1 to continue to be used. Compared to replacing the entire nut, only the small nylon ring 3 needs to be replaced, significantly reducing material consumption and minimizing waste of parts and resources. Furthermore, the second thread 5 engages with the screw thread during tightening, creating a mechanical locking effect and increasing friction. Combined with the radial clamping force applied to the screw by the deformed nylon ring 3, a double locking effect is achieved, effectively preventing loosening and making the system more practical.

[0034] The working principle of the above embodiment is as follows: During use, the nut body 1 and nylon ring 3 can be locked to the outside of the screw through the first thread 4 and the second thread 5. The second thread 5 can engage with the screw thread, forming a mechanical locking effect. Combined with the radial clamping force applied to the screw after the nylon ring 3 deforms, a double locking effect is achieved, effectively preventing loosening and making it more practical. When the nut body 1 is frequently disassembled and reassembled, the nylon ring 3 may fail. At this time, the nylon ring 3 can be removed from the inside of the nut body 1 by pulling the four locking rods 202 outward. When the four locking rods 202 are pulled outward, they will move out of the corresponding locking holes 206, thereby releasing the restriction on the nylon ring 3. Then the nylon ring 3 can be taken out from the inside of the nut body 1, and a new nylon ring 3 can be snapped into the inside of the nut body 1 through the snap-fit ​​mechanism 2. During installation, the nylon ring 3 needs to be... The T-shaped block 7 and rectangular block 9 on the surface are aligned with the T-shaped groove 6 and rectangular groove 8 respectively, which ensures that the first thread 4 and the second thread 5 are compatible. Then, the four locking rods 202 are pulled outward to prevent them from obstructing the insertion of the nylon ring 3. Then, the bottom surface of the nylon ring 3 is inserted into the nut body 1, so that the guide ring 211 on the bottom surface of the nylon ring 3 is inserted into the guide groove 209. At this time, the bottom surface of the nylon ring 3 is in contact with the reserved groove 207 and the first groove 208. When the bottom surface of the guide ring 211 contacts the guide groove 209 and the second groove 210, it can increase the friction between the nut body 1 and the nylon ring 3, making the nylon ring 3 more stable. Then, the four locking rods 202 are released, and the four locking rods 202 will be reset by the elastic force generated by the deformation of the corresponding limit spring 205, so that the four locking rods 202 spring into the lock hole 206 to limit the nylon ring 3, thus completing the snapping work of the nylon ring 3.
