Description

Technical Field

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

[0002] Fasteners are one of the essential basic components in industrial production, especially in mechanical equipment, where their performance directly affects the safe operation of the entire equipment. With the advancement of industrial technology, the requirements for fasteners are becoming increasingly stringent. They not only need sufficient strength to ensure the safety of the connection, but also need to have good fatigue resistance, corrosion resistance, and other properties.

[0003] As a type of fastener, rivet nuts play an important role in various connection structures. However, existing rivet nuts often face the problem of loosening during use, which may affect the stability and safety of the connection. Therefore, improving the design of rivet nuts and enhancing their anti-loosening performance is particularly important. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an anti-loosening rivet nut, which has the advantages of optimizing the fastening effect of rivet nut installation, preventing rivet nuts from easily loosening, and improving the stability and safety of rivet nuts. It solves the problem that existing rivet nuts are prone to loosening during use, affecting the stability and safety of the connection.

[0005] To achieve the above objectives, this application provides the following technical solution: an anti-loosening rivet nut, comprising a nut body, the nut body including a top plate and a rod, the center of the top plate being fixedly connected to the top end of the rod, the bottom surface of the top plate being fixedly connected with equidistantly arranged anti-slip protrusions, the outer circumferential surface of the rod being fixedly connected with four equidistantly arranged elastic retaining plates, the outer wall of each elastic retaining plate being fixedly connected with equidistantly arranged anti-slip protrusions, the bottom of the rod being slidably sleeved with a base plate, the upper surface of the base plate being fixedly connected with a limiting ring, the upper surface of the limiting ring being provided with equidistantly arranged anti-slip protrusions, and the bottom of the rod being threadedly connected with a positioning ring via an external thread, the upper surface of the positioning ring being in contact with the bottom surface of the base plate.

[0006] The above solution addresses the issue that existing rivet nuts are prone to loosening during use, affecting the stability and safety of the connection. By installing an elastic plate with anti-slip protrusions at the top of the outer wall of the rod, the frictional resistance between the rivet nut and the bottom of the fixed workpiece can be increased. Furthermore, by installing equidistantly arranged anti-slip protrusions on the bottom surface of the top plate, the frictional resistance between the rivet nut and the upper surface of the fixed workpiece is increased. Rotating the positioning ring moves the bottom plate and the limiting ring upwards, causing the limiting ring to press against the bottom of the workpiece, thus expanding the frictional area between them. This further optimizes the fastening effect of the rivet nut installation, preventing the rivet nut from easily loosening and improving its stability and safety.

[0007] Furthermore, the top plate is made of aluminum alloy, and the rod is also made of aluminum alloy.

[0008] Through the above solution, the aluminum alloy nut body not only has good lightweight properties, but also excellent corrosion resistance and a certain strength, making it suitable for use in a variety of environments.

[0009] Furthermore, the elastic plate is made of stainless steel.

[0010] Through the above solution, the flexible plate made of stainless steel can ensure that it is not easy to rust during long-term use, maintain good elasticity and wear resistance, and the hardness of stainless steel can also effectively prevent loosening and improve connection stability.

[0011] Furthermore, the rod has four elongated holes arranged at equal intervals inside, and the elongated holes and the elastic retaining plate are staggered.

[0012] The above scheme allows the elongated holes, which are staggered with the elastic plate, to cause the elastic plate to flip upwards during the compression deformation of the rod, thus contacting the bottom surface of the positioned workpiece.

[0013] Furthermore, the inner wall of the rod is provided with a groove, and the groove is at the same height as the bottom surface of the elastic plate.

[0014] The above method causes the bending position of the rod to be squeezed and deformed, which is exactly located in the groove at the bottom of the elastic plate, so that the elastic plate flips over as a whole to position the rivet nut.

[0015] Furthermore, four equally spaced sliders are fixedly connected to the inner wall of the base plate, and four equally spaced grooves are provided at the bottom of the rod. The outer surfaces of the sliders are slidably connected to the rod through the grooves.

[0016] The above scheme restricts the base plate and the limiting ring, preventing them from rotating and ensuring that the limiting ring always moves vertically up and down.

[0017] Furthermore, the limiting ring is located at the edge of the upper surface of the base plate, and both the base plate and the limiting ring are made of lightweight metal.

[0018] The above solution reduces the overall weight of the rivet nut while maintaining good strength and corrosion resistance through the use of a lightweight metal base plate and a limiting ring.

[0019] Furthermore, the bottom of the inner wall of the rod is provided with an internal thread, and a screw is provided inside the rod. The screw is threadedly connected to the rod through the internal thread at the bottom of the inner wall of the rod.

[0020] The above method allows an external rivet gun to drive the screw to rotate, thereby causing the rod to be squeezed and deformed, thus completing the fixed installation of the rivet nut.

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

[0022] This anti-loosening rivet nut increases the frictional resistance between the rivet nut and the bottom of the fixed workpiece by setting an elastic plate with anti-slip protrusions at the top of the outer wall of the rod. It also increases the frictional resistance between the rivet nut and the upper surface of the fixed workpiece by setting equidistant anti-slip protrusions on the bottom surface of the top plate. By rotating the positioning ring, the bottom plate and the limiting ring are moved upward, so that the limiting ring is pressed against the bottom of the workpiece, expanding the friction area between them and the workpiece. This further optimizes the fastening effect of the rivet nut installation, prevents the rivet nut from loosening easily, and improves the stability and safety of the rivet nut. It solves the problem that existing rivet nuts are prone to loosening during use, which affects the stability and safety of the connection. Attached Figure Description

[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 4This embodiment of an anti-loosening rivet nut includes a nut body 1, which includes a top plate 101 and a rod 102. The center of the top plate 101 is fixedly connected to the top of the rod 102. The bottom surface of the top plate 101 is fixedly connected with equidistant anti-slip protrusions. The outer circumferential surface of the rod 102 is fixedly connected with four equidistant elastic clamping plates 2. The outer wall of each elastic clamping plate 2 is fixedly connected with equidistant anti-slip protrusions. The bottom of the rod 102 is slidably sleeved with a bottom plate 3. The upper surface of the bottom plate 3 is fixedly connected with a limiting ring 4. The upper surface of the limiting ring 4 is provided with equidistant anti-slip protrusions. The bottom of the rod 102 is threadedly connected with a positioning ring 5 through an external thread. The upper surface of the positioning ring 5 is in contact with the bottom surface of the bottom plate 3.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The top plate 101 is made of aluminum alloy, the rod 102 is made of aluminum alloy, and the nut body 1 made of aluminum alloy not only has good lightweight properties, but also has excellent corrosion resistance and a certain strength, making it suitable for use in a variety of environments.

[0032] Please see Figure 1 , Figure 2 and Figure 4 The elastic plate 2 is made of stainless steel. The stainless steel elastic plate 2 can ensure that it is not easy to rust during long-term use, maintain good elasticity and wear resistance, and the hardness of stainless steel can also effectively prevent loosening and improve connection stability.

[0033] Please see Figure 1 , Figure 2 and Figure 4 The rod 102 has four equally spaced elongated holes 9 inside. The elongated holes 9 and the elastic clamping plate 2 are staggered. The elongated holes 9 staggered with the elastic clamping plate 2 can cause the elastic clamping plate 2 to flip upward during the compression deformation of the rod 102 and contact the bottom surface of the positioned workpiece.

[0034] Please see Figure 3 The inner wall of the rod 102 is provided with a groove 10. The groove 10 is at the same height as the bottom surface of the elastic plate 2, so that the bending position of the rod 102 due to compression deformation is exactly located at the groove 10 at the bottom of the elastic plate 2, so that the elastic plate 2 is flipped over as a whole to position the rivet nut.

[0035] Please see Figure 3 and Figure 4Four equally spaced sliders 6 are fixedly connected to the inner wall of the base plate 3. Four equally spaced grooves 7 are provided at the bottom of the rod 102. The outer surfaces of the sliders 6 are slidably connected to the rod 102 through the grooves 7 to restrict the base plate 3 and the limiting ring 4, prevent the base plate 3 and the limiting ring 4 from rotating, and make the limiting ring 4 always move vertically.

[0036] Please see Figure 1 , Figure 3 and Figure 4 The limiting ring 4 is set at the edge of the upper surface of the base plate 3. Both the base plate 3 and the limiting ring 4 are made of lightweight metal. The lightweight metal base plate 3 and the limiting ring 4 reduce the overall weight of the rivet nut while maintaining good strength and corrosion resistance.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the inner wall of the rod 102 is provided with an internal thread, and the inside of the rod 102 is provided with a screw 8. The screw 8 is threadedly connected to the rod 102 through the internal thread at the bottom of the inner wall of the rod 102. An external rivet gun can be used to drive the screw 8 to rotate, thereby causing the rod 102 to be squeezed and deformed, thus completing the fixed installation of the rivet nut.

[0038] In this embodiment, an anti-loosening rivet nut is provided with an elastic retaining plate 2 with anti-slip protrusions at the top of the outer wall of the rod 102, which increases the frictional resistance between the rivet nut and the bottom of the fixed workpiece. The anti-slip protrusions arranged at equal intervals on the bottom surface of the top plate 101 further increase the frictional resistance between the rivet nut and the upper surface of the fixed workpiece. Rotating the positioning ring 5 causes the bottom plate 3 and the limiting ring 4 to move upwards, making the limiting ring 4 press against the bottom of the workpiece, expanding the frictional area between them, further optimizing the fastening effect of the rivet nut installation, preventing the rivet nut from easily loosening, improving the stability and safety of the rivet nut, and solving the problem that existing rivet nuts are prone to loosening during use, affecting the stability and safety of the connection.

[0039] It should be noted that the base plate 3 and the limit ring 4 are integrated.

[0040] The working principle of the above embodiments is as follows:

[0041] When installing the rivet nut, insert the rivet nut into the hole on the workpiece, and then use an external rivet gun to drive the screw 8 inside the rod 102 to rotate. Because the bottom of the inner wall of the rod 102 has internal threads, the rotation of the screw 8 will cause the rod 102 to be compressed and deformed. This compression and deformation of the rod 102 causes the elastic retaining plate 2 to flip upwards under the compression of the rod 102, contacting the bottom surface of the positioned workpiece and generating pressure. The anti-slip protrusions increase friction. Simultaneously, the deformation of the rod 102 also causes the bottom surface of the top plate 101 to make tight contact with the upper surface of the workpiece. The anti-slip protrusions on the bottom surface of the top plate 101 also increase friction. After the rivet nut is installed... The base plate 3 and the limiting ring 4 are fitted onto the bottom of the rod 102. Then, the positioning ring 5 is rotated and installed onto the bottom of the rod 102. By rotating the positioning ring 5, the base plate 3 and the limiting ring 4 are moved upward until the limiting ring 4 is pressed against the bottom of the workpiece. The pressing of the limiting ring 4 further increases the friction area between it and the workpiece, enhancing the fastening effect of the rivet nut. When the rod 102 is fully deformed and tightly fixed to the workpiece, under the combined action of the elastic clamping plate 2 with anti-slip protrusions, the top plate 101, and the limiting ring 4, the rivet nut is firmly installed on the workpiece, preventing the rivet nut from easily loosening during use and improving the stability and safety of the connection.
