Description

Technical Field

[0001] The present application belongs to the technical field of nuts, and in particular relates to a high temperature resistant nylon nut. Background Art

[0002] Nylon, also known as polyamide, is an important polymer material with the characteristics of high strength, high toughness, wear resistance, high temperature resistance, chemical corrosion resistance, etc. With the widespread application of nylon materials in industry, people began to explore the use of nylon in the manufacture of fasteners, such as nuts. Polymer nylon nuts have gradually become an important type of fasteners due to their excellent wear resistance, corrosion resistance and insulation. Compared with traditional metal nuts, nylon nuts have the advantages of light weight, not easy to rust, and non-conductive. These advantages make nylon nuts have unique advantages in specific applications. High temperature resistant nylon will use nylon 66 and nylon 6, which can maintain high strength and toughness.

[0003] The patent with publication number CN219994154U discloses an anti-loosening nut, including a nut body, an inner thread is arranged on the inner wall of the nut body, one side of the nut body has a flat end face, the inner side of the flat end face has a plurality of protrusions extending horizontally toward the center line direction of the nut body and forming a clamping edge, and the aperture formed by the plurality of clamping edges is smaller than the inner diameter of the nut body.

[0004] The above patent solves the loosening problem by adding a clamping edge structure and increasing the locking force through interference fit between the clamping edge and the thread. However, due to its special structure, the nut is prone to uneven force during actual use, which produces a huge shear force on the bolt, causing damage to the outer ring and shortening the service life. Improvement is needed. Utility Model Content

[0005] The purpose of this application is to provide a high temperature resistant nylon nut that can solve the above problems.

[0006] The purpose of this application is to provide a high temperature resistant nylon nut, comprising:

[0007] A locking member having a threaded hole disposed therein;

[0008] A contact member, comprising a supporting portion and a wrapping portion connected to one end of the locking member and wrapping the locking member;

[0009] A buffer member, disposed between the contact member and the locking member;

[0010] Wherein, a cavity for placing a buffer is arranged inside the contact piece, and the outer wall of the buffer piece is in contact with the inner wall of the cavity.

[0011] Adopt the above-mentioned high-temperature resistant nylon nut. The locking part serves as the fastening part of the nut and is responsible for cooperating with the bolt through the internal threaded hole to achieve the fastening function. It is made of high-temperature resistant nylon material, has excellent high-temperature resistance performance, can maintain stable mechanical properties in a high-temperature environment, and reduce the assembly error caused by temperature change. The contact part includes a supporting part and a wrapping part that is connected to one end of the locking part and wraps the locking part, and is used to provide additional support and limit, to prevent the contact part from separating from the locking part. It is also made of high-temperature resistant material. The buffer part is arranged between the contact part and the locking part to increase the pre-tightening force between the nut and the screw rod after installation, so that it is not easy to loosen and fall off under the influence of vibration and other external forces, and improve the reliability and stability of fastening.

[0012] Further, a limiting convex ring extending outwards is arranged at one end of the locking part in contact with the contact part, the wrapping part wraps outside the limiting convex ring, and the inside of the wrapping part is connected to the inner wall of the chamber.

[0013] The limiting convex ring serves as a connection point between the locking part and the contact part. Its outward extending structure increases the contact area, thereby improving the connection strength between the two. This design helps to prevent relative displacement or loosening during fastening or vibration. The setting of the limiting convex ring provides a clear positioning reference for the wrapping part of the contact part. The wrapping part can tightly wrap outside the limiting convex ring to ensure the accurate position relationship between the two, not only improving the assembly accuracy, but also helping to maintain the stability of the nut during long-term use.

[0014] Further, a contact flange is arranged on the supporting part, and friction lines are arranged on the contact flange.

[0015] The setting of the contact flange can increase the contact area, thereby improving the fastening effect. The friction lines on the contact flange can further increase the friction force between the nut and the connected part, helping to prevent the nut from loosening during the fastening process or under the action of external forces, so as to ensure the stability and reliability of the connection. At the same time, by increasing the friction force, the nut can more effectively transfer and bear the fastening force from the bolt to ensure the close fit between the connected parts.

[0016] Further, a first through hole is also arranged on the supporting part. The first through hole penetrates the supporting part, and a wear-resistant protective layer is arranged on the inner wall of the first through hole.

[0017] The setting of the first through hole can, to a certain extent, reduce the overall weight of the nut, which has beneficial effects for application scenarios that require lightweight design. At the same time, the setting of the first through hole can also protect the buffer member, preventing it from coming into contact with the threads of the bolt and avoiding jamming caused by the position and deformation of the buffer member. In addition, the setting of the wear-resistant protective layer can enhance the wear resistance of the inner wall of the first through hole, reduce the aperture change or damage caused by friction and wear, and extend the service life of the nut.

[0018] Furthermore, a protrusion extending into the chamber is provided on the support portion. A second through hole communicating with the first through hole is formed in the protrusion, and the outer wall of the protrusion is attached to the inner wall of the buffer member.

[0019] As a part of the support portion, the protrusion extending into the chamber increases the contact area with the buffer member, playing a role in supporting the buffer member. At the same time, the second through hole formed in the protrusion communicates with the first through hole, facilitating the passage of the bolt and protecting the buffer member, isolating it from the bolt.

[0020] Furthermore, chamfers are provided at the openings of the first through holes, and rounded corners are provided on the outer wall of the second through hole.

[0021] The design of the chamfers at the openings of the first through holes can reduce the stress concentration phenomenon at the openings of the first through holes. When the nut is subjected to external forces, it can also make the openings of the first through holes smoother, reducing friction and wear with installation tools (such as screwdrivers, wrenches, etc.). This helps to insert the tool more smoothly during the installation process and improve the installation efficiency. The rounded corners on the outer wall of the second through hole are used to protect the buffer member. When the buffer member is sleeved on the second through hole, the rounded corners can reduce friction and scratching with the buffer member, preventing damage to the surface of the buffer member. At the same time, the rounded corners can also make the outer wall of the second through hole smoother, facilitating the sleeving of the buffer member, helping to more easily guide the buffer member into the correct position during the installation process, and reducing the installation difficulty and time.

[0022] The beneficial effects of this application are:

[0023] 1. By adopting the above-mentioned high-temperature resistant nylon nut, the locking member, as the fastening part of the nut, is responsible for cooperating with the bolt through the threaded hole inside it to achieve the fastening function. It is made of high-temperature resistant nylon material and has excellent high-temperature resistance. It can maintain stable mechanical properties in high-temperature environments and reduce assembly errors caused by temperature changes;

[0024] 2. The setting of the contact flange can increase the contact area, thereby improving the tightening effect. The friction lines on the contact flange can further increase the friction between the nut and the connected part, which helps prevent the nut from loosening during the tightening process or when subjected to external forces, thereby ensuring the stability and reliability of the connection. At the same time, by increasing the friction, the nut can more effectively transmit and withstand the tightening force from the bolt, ensuring a tight fit between the connecting parts;

[0025] 3. The buffer is arranged between the contact part and the locking part to increase the pre-tightening force between the nut and the screw after installation, so that it is not easy to loosen or fall off when affected by vibration and other external forces, thereby improving the reliability and stability of fastening.

[0031] The following is a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] Example 1:

[0033] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a high-temperature resistant nylon nut, including:

[0034] A locking member 100, which is internally provided with a threaded hole 110;

[0035] A contact member 200, including a support portion 210 and a wrapping portion 220 that is connected to one end of the locking member 100 and wraps the locking member 100;

[0036] A buffer member 300, which is arranged between the contact member 200 and the locking member 100;

[0037] Wherein, a chamber 230 for placing the buffer member 300 is arranged in the contact member 200, and the outer wall of the buffer member 300 fits with the inner wall of the chamber 230.

[0038] In some embodiments of the embodiment of the present application, as Figure 1 shown, by using the above-mentioned high-temperature resistant nylon nut, the locking member 100, as the fastening part of the nut, is responsible for cooperating with the bolt through the threaded hole 110 inside it to achieve the fastening function. It is made of high-temperature resistant nylon material and has excellent high-temperature resistance performance, and can maintain stable mechanical properties in a high-temperature environment, reducing the assembly error caused by temperature change. The contact member 200 includes a support portion 210 and a wrapping portion 220 that is connected to one end of the locking member 100 and wraps the locking member 100, which is used to provide additional support and limit, to prevent the contact member 200 from separating from the locking member 100, and it is also made of high-temperature resistant material. The buffer member 300 is arranged between the contact member 200 and the locking member 100, increasing the pre-tightening force between the nut and the screw rod after installation, making it not easy to loosen and fall off under the influence of vibration and other external forces, and improving the reliability and stability of fastening.

[0039] Furthermore, a limiting convex ring 120 extending outward is arranged at one end of the locking member 100 in contact with the contact member 200, the wrapping portion 220 wraps outside the limiting convex ring 120, and the inside of the wrapping portion 220 is connected to the inner wall of the chamber 230.

[0040] The limiting protrusion 120 serves as a connection point between the locking member 100 and the contact member 200. Its outwardly extending structure increases the contact area, thereby improving the connection strength between the two. This design helps prevent relative displacement or loosening during tightening or vibration. The setting of the limiting protrusion 120 provides a clear positioning reference for the wrapping portion 220 of the contact member 200. The wrapping portion 220 can be tightly wrapped around the limiting protrusion 120 to ensure that the positional relationship between the two is accurate, which not only improves the assembly accuracy, but also helps to maintain the stability of the nut during long-term use.

[0043] like Figure 1 and Figure 2 As shown, a contact flange 240 is provided on the support portion 210 , and a friction pattern 241 is provided on the contact flange 240 .

[0044] In the embodiment of the present application, the contact flange 240 can increase the contact area, thereby improving the fastening effect. The friction lines 241 on the contact flange 240 can further increase the friction between the nut and the connected part, which helps prevent the nut from loosening during the fastening process or when subjected to external forces, thereby ensuring the stability and reliability of the connection. At the same time, by increasing the friction, the nut can more effectively transmit and withstand the fastening force from the bolt, ensuring a tight fit between the connecting parts.

[0048] In the embodiment of the present application, the provision of the first through hole 211 can, to a certain extent, reduce the overall weight of the nut, which has a beneficial effect on application scenarios that require lightweight design. At the same time, the provision of the first through hole 211 can also protect the buffer member 300 from coming into contact with the threads of the bolt, and prevent the buffer member 300 from getting stuck due to its position and deformation. In addition, the provision of the wear-resistant protective layer can enhance the wear resistance of the inner wall of the first through hole 211, reduce the aperture change or damage caused by friction and wear, and extend the service life of the nut.

[0049] Embodiment 4:

[0050] The embodiment of the present application provides a high-temperature resistant nylon nut. In addition to including the above technical features, the high-temperature resistant nylon nut of the embodiment of the present application further includes the following technical features.

[0051] As Figure 1 and Figure 2 shown, a protrusion 212 extending into the chamber 230 is provided on the support portion 210. A second through hole 213 communicating with the first through hole 211 is formed in the protrusion 212, and the outer wall of the protrusion 212 is in contact with the inner wall of the buffer member 300.

[0052] In the embodiment of the present application, the protrusion 212, as a part of the support portion 210, extends into the chamber 230 to increase the contact area with the buffer member 300, playing a role in supporting the buffer member 300. At the same time, the second through hole 213 formed in the protrusion 212 communicates with the first through hole 211 to facilitate the passage of the bolt and protect the buffer member, isolating it from the bolt.

[0053] Furthermore, chamfers are provided at the openings of the first through holes 211, and rounded corners are provided on the outer wall of the second through holes 213.

[0054] In some embodiments of the present application, the design of the chamfers at the openings of the first through holes 211 can reduce the stress concentration phenomenon at the openings of the first through holes 211.

When the buffer member 300 is sleeved on the second through holes 213, the rounded corners can reduce the friction and scratching with the buffer member 300, prevent the surface of the buffer member 300 from being damaged. At the same time, the rounded corners can also make the outer wall of the second through holes 213 smoother, facilitating the sleeving of the buffer member 300, and helping to more easily guide the buffer member 300 into the correct position during the installation process, reducing the installation difficulty and time.
