Description

Technical Field

[0001] The utility model relates to the technical field of rivets, in particular to a plastic nylon anti-loosening rivet. Background Art

[0002] Plastic nylon rivets are widely used in the fields of industry, construction, automobiles, etc. They are mainly used to connect two or more components together, especially in various lightweight structure connections. Because they have the advantages of light weight, corrosion resistance, wear resistance, etc., however, in the working environment that needs to bear high-frequency vibration or high load for a long time, many deficiencies have emerged in the traditional ones.

[0003] During the use of many existing plastic nylon rivets, due to the influence of external forces, vibrations or thermal expansion and other factors, they become loose or fall off. The removal of the rivets leads to connection failure. This problem is particularly serious in application scenarios that require long-term stability, vibration environments and long-term high-pressure scenarios, such as the assembly of transportation components, the reinforcement of building structures, the assembly of electronic products and industrial products, etc., which will directly affect the reliability and connection strength of the rivets. Some anti-loosening designs are relatively complex, and the rivet structure design is not simplified enough. Usually, complex and laborious pressing operations are required, increasing the manufacturing cost and assembly difficulty of the rivets. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a plastic nylon anti-loosening rivet to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A plastic nylon anti-loosening rivet includes a male part plug and a female part buckle, and the male part plug is inserted and connected inside the female part buckle.

[0006] The male part plug includes a pressing platform surface, a plug main rod, a plug groove, a plug protrusion and a plug end buckle. The plug main rod is fixedly connected to the bottom of the pressing platform surface. The plug groove is opened at the bottom of the plug main rod. The plug end buckle is fixedly connected to the bottom of the plug main rod. The plug protrusion is fixedly connected to the outside above the plug main rod.

[0007] The female part buckle includes a buckle wall body, an elastic buckle, a wall body slot, a buckle protrusion and a receiving platform surface. The elastic buckle is fixedly connected to the bottom of the buckle wall body. The wall body slot is opened inside the buckle wall body. The receiving platform surface is fixedly connected to the top of the buckle wall body. The buckle protrusion is arranged inside the receiving platform surface.

[0008] Preferably, the pressing platform surface and the plug main rod are vertically distributed in space. The force on the pressing platform surface is evenly concentrated at the front end of the plug main rod and transmitted to the end of the plug main rod. This design ensures that the rivet can stably enter the positioning groove, thereby improving the accuracy and speed of assembly.

[0009] Preferably, the bottom of the buckle wall body adopts a quarter-equal-volume elastic buckle. After the quarter-equal-volume elastic buckle is riveted with the rivet, the female part buckle locks the male part plug pin, further improving the fatigue life of the rivet and addressing the problems of loosening and failure of the rivet during use.

[0010] Preferably, a wall body hollow groove is provided inside the buckle wall body. Above the wall body hollow groove, a wall body buckle edge is provided, and above the wall body buckle edge, a wall body guiding edge is provided.

[0011] Preferably, the size of the plug pin protrusion is larger than the size inside the buckle wall body. Under the action of the downward pressing force, when the guiding assembly is completed, an anti-withdrawal fit is formed. Continuing to press the pressing platform surface will cause the buckle at the end of the plug pin to complete an interference fit through the elastic buckle. By applying an external force to closely combine the two, a certain amount of friction and connection force are generated, thus achieving a firm connection.

[0012] Preferably, the internal dimensions of the plug pin main rod and the buckle wall body are the same, ensuring that the rivet can be accurately aligned with the materials to be riveted, reducing the error rate during the assembly process and improving the assembly speed.

[0013] Preferably, the male part plug pin and the female part buckle are made of plastic nylon material, which is lightweight, corrosion-resistant, and wear-resistant, suitable for use in a variety of complex environments. The plastic nylon has good elasticity, which can further enhance the anti-fatigue performance of the rivet and is suitable for long-term use scenarios.

[0014] Preferably, the cooperation between the plug pin main rod and the buckle wall body ensures that the rivet can smoothly enter the predetermined position during the pressing process, forming a complete non-working plastic nylon anti-withdrawal rivet. The male part plug pin and the female part buckle of the plastic nylon anti-withdrawal rivet will be initially assembled and formed as an integral part.

[0015] Preferably, the setting of the buckle protrusion is used to further ensure that the rivet will not be loosened by external forces before installation is completed, ensuring that the rivet can maintain a high structural integrity during transportation, storage, and the early stage of production, and avoiding problems such as parts scattering or being unable to be pre-assembled.

[0016] Preferably, the top of the buckle wall body is provided with a first riveted platform surface and a second riveted platform surface, and the fixed state of the rivet after complete pressing is formed by the first riveted platform surface and the second riveted platform surface.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. The plastic nylon anti-retraction rivet uses the male part pin and the female part lock to complete the pin-type tight fit, so that the male part expands the female part to play a riveting role. The male and female parts structural design adds a guide design, which allows the downward pressure to better pass through the inner surface of the female buckle to complete the riveting effect. The male and female parts structural design adds an anti-retraction design. This method keeps the riveted combination structure tightly fitted, improves the efficiency of rivet use, and extends the service life of the device.

[0019] 2. The plastic nylon anti-retraction rivet adds a buckle structure at the tail of the male part pin, so that it can better release the tension to the surroundings during the downward pressure process, thereby completing the riveting with the female part buckle. After the matching is completed, the buckle pushes out the female part lock buckle, and the inverted structural design makes the male part pin and the female part buckle complete a tight match, so that the male part pin cannot be loosened, thereby achieving a double-layer structure anti-retraction effect, and increasing the security of the overall structure.

DETAILED DESCRIPTION

[0027] 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, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 The utility model provides a technical solution: a plastic nylon anti-backout rivet, including a male pin and a female buckle, the male pin is plugged into the inside of the female buckle, the male pin and the female buckle are made of plastic nylon material, which is light, corrosion-resistant and wear-resistant, and is suitable for use in a variety of complex environments. Plastic nylon has good elasticity, which can further enhance the anti-fatigue performance of the rivet and is suitable for long-term use scenarios.

[0029] The public component latch includes a pressing platform surface 101, a latch main rod 102, a latch groove 103, a latch protrusion 104 and a latch end buckle 105. The latch main rod 102 is fixedly connected to the bottom of the pressing platform surface 101, the latch groove 103 is opened at the bottom of the latch main rod 102, the latch end buckle 105 is fixedly connected to the bottom of the latch main rod 102, and the latch protrusion 104 is fixedly connected to the outside above the latch main rod 102.

[0030] The mother buckle includes a buckle wall 201, an elastic buckle 202, a wall groove 203, a buckle protrusion 204 and a receiving platform surface 205. The elastic buckle 202 is fixedly connected to the bottom of the buckle wall 201, the wall groove 203 is opened inside the buckle wall 201, the receiving platform surface 205 is fixedly connected to the top of the buckle wall 201, the buckle protrusion 204 is arranged inside the receiving platform surface 205, the buckle wall 201 is provided with a wall hollow groove 208, and a wall buckle is arranged above the wall hollow groove 208. Edge 207, a wall guide edge 206 is arranged above the wall buckle edge 207, the male part pin passes through the hollow opening of the inner wall of the rivet female part buckle, and the male part pin main rod 102 is inserted into the central opening of the female part receiving platform surface 205, and is assembled with the buckle wall 201 in the process, thereby forming a complete unworked plastic nylon anti-fading rivet. Although the final tightening or loading has not yet been carried out, the male and female parts of the rivet have been tightly matched through a specific structure and combined into a whole. This structure has significant advantages in the production and assembly links.

[0031] The pressing platform surface 101 and the latch main rod 102 are vertically distributed in space. The force on the pressing platform surface 101 is evenly concentrated on the front end of the latch main rod 102 and transmitted to the end of the latch main rod 102. This design ensures that the rivet can stably enter the positioning groove, thereby improving the accuracy and speed of assembly.

[0032] The bottom of the buckle wall body 201 adopts a four-equal-volume elastic buckle 202. After the four-equal-volume elastic buckle 202 is riveted with the rivet, the female part buckle locks the male part plug, further improving the fatigue life of the rivet and addressing the problems of loosening and failure of the rivet during use.

[0033] The size of the plug protrusion 104 is larger than the size inside the buckle wall body 201. Under the action of a downward pressing force, when the guiding assembly is completed, an anti-withdrawal fit is formed. Continuing to press the pressing platform surface 101 will cause the plug end buckle 105 to complete an interference fit through the elastic buckle 202. By applying an external force, the two are tightly combined, generating a certain amount of frictional force and connection force, thereby achieving a firm connection. The cooperation between the plug main rod 102 and the buckle wall body 201 ensures that the rivet can smoothly enter the predetermined position during the pressing process, forming a complete non-working plastic nylon anti-withdrawal rivet. The male part plug of the plastic nylon anti-withdrawal rivet and the female part buckle will be initially assembled and formed as an integral component. The internal dimensions of the plug main rod 102 and the buckle wall body 201 are the same, ensuring that the rivet can be accurately aligned with the material to be riveted, reducing the error rate during the assembly process and improving the assembly speed.

[0034] The setting of the buckle protrusion 204 is used to further ensure that the rivet will not be loosened by external forces before installation, ensuring that the rivet can maintain a high structural integrity during transportation, storage, and the early stage of production, and avoiding problems such as parts scattering or being unable to be pre-assembled.

[0035] The top of the buckle wall body 201 is provided with a riveted platform surface one 301 and a riveted platform surface two 302, and the fixed state of the rivet after complete pressing is formed by the riveted platform surface one 301 and the riveted platform surface two 302.

[0036] When in use, during the assembly process, press the pressing platform surface 101, thereby causing the plug main rod 102 to enter the buckle wall body 201, resulting in the contact between the plug guiding edge 107 and the wall body guiding edge 206. Both sides are beveled for guiding assembly, effectively reducing the work done during the pressing assembly, thereby reducing the assembly difficulty and improving the production efficiency. After the rivet assembly is completed, the male part plug of the rivet is completely pressed into the female part buckle, and its special buckle structure will lock the plug. The plug anti-withdrawal buckle 106 and the wall body buckle edge 207 form a tight fit, preventing it from loosening or retreating during subsequent use, ensuring that it can maintain a high degree of stability under external forces. During use, the end depression cooperates with the elastic buckle 202. The elastic buckle 202 expands outward under the tension of the male part plug of the rivet, and the elastic characteristics unique to the nylon material drive the buckle to contract inward, and the end depression and the elastic buckle 202 have an interference fit.
