Description

Technical Field

[0001] The utility model relates to the technical field of pressure rivet nuts, in particular to a pressure rivet nut assembly. Background Art

[0002] Compression rivet nuts, also known as rivet nuts and self-locking nuts, are a type of nut used on thin plates or sheet metals. They are round in shape with embossed teeth and guide grooves on one end. The principle is that the embossed teeth are pressed into the preset holes of the sheet metal. Generally speaking, the aperture of the preset hole is slightly smaller than the embossed teeth of the compression rivet nut. The pressure causes the teeth of the compression rivet nut to squeeze into the plate, causing plastic deformation around the preset hole. The deformed object is squeezed into the guide groove, thereby producing a locking effect.

[0003] In the prior art, when thinner plates or sheet metals need to be connected and fixed, they need to be fixed using a rivet nut assembly. Since the rivet nut needs to be pressed into a slot opened in one of the plates for fixation before fixation, and then fixed under the action of other structures, when it needs to be disassembled, special tools are required to complete the disassembly, and the operation is complicated, which not only seriously affects the disassembly efficiency of the rivet nut assembly, but also increases the labor intensity of the staff and reduces the practicality of the rivet nut assembly. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem of low working efficiency during use of the above-mentioned equipment due to the inability to quickly disassemble the self-clinching nut, and thus propose a self-clinching nut assembly.

[0006] Preferably, the inner surface wall of the nut body is threadedly connected with a bolt, and the outer surface wall of the bolt is movably sleeved with a second thin plate.

[0007] Preferably, the outer wall of the nut body is provided with embossed teeth, and an elastic gasket is provided on one side of the outer wall of the nut body, and the elastic gasket is arranged on the outer wall of the embossed teeth.

[0008] Preferably, the outer surface wall of the nut body is provided with two thread grooves, and the inner surface walls of the two thread grooves are both movably inserted with threaded rods.

[0009] Preferably, the outer walls of the two threaded rods are movably connected to a mounting plate, and one side of the outer walls of the two mounting plates is fixedly mounted with a rubber pad, and one side of the outer wall of the rubber pad is in contact with the outer wall of the bolt.

[0010] Preferably, two installation boxes are fixedly installed on the outer surface wall of the nut body, and movable blocks are movably embedded in the inner surface walls of the two installation boxes.

[0011] Preferably, an insertion groove is provided on the top of the two movable blocks, a limiting rod is movably inserted into the inner surface walls of the two insertion grooves, and two magnets are provided on the inner surface walls of the two movable blocks.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] The utility model is used in that after the plate or sheet metal is fixed by using the self-clinching nut assembly under the interaction of a series of components, when it is necessary to disassemble it, the staff first takes out the bolt from the inside of the nut body under the operation of the staff, thereby disassembling the first thin plate and the second thin plate, and then, under the interaction of the embedded groove, the movable plate and the push rod, the nut body can be taken out from the inside of the fixing groove opened on the outer wall of the first thin plate, and no special tools are needed to disassemble the self-clinching nut, which not only reduces the labor intensity of the staff, but also improves the efficiency of disassembling the self-clinching nut assembly, thereby greatly improving its practicality.

[0014] During use, the present invention can clamp and limit the bolts through the interaction of a series of components when the self-clinching nut assembly is used to fix the plate or sheet metal, thereby increasing the friction force of the bolt inside the nut body and preventing the self-clinching nut assembly from loosening during use, thereby improving the fixing effect on the plate or sheet metal and further improving the practicality of the self-clinching nut assembly.

[0025] The effect achieved by the entire embodiment 1 is that when it is necessary to disassemble the plate or sheet metal fixedly connected by the self-clinching nut assembly, first, under the operation of the staff, rotate the bolt 4 to remove it from the inside of the nut body 3, so that the bolt 4 no longer fixes the first thin plate 1 and the second thin plate 5, so that it can be easily disassembled. Then, it is necessary to remove the nut body 3 from the inside of the fixing groove 2. Under the operation of the staff, press one end of the push rod 11 fixedly inserted inside the movable plate 10, so that the movable plate 10 moves toward the side of the first thin plate 1 inside the embedded groove 9, thereby driving the other end of the push rod 11 to contact the first thin plate 1. During the continuous pressing process, the push rod 11 will play a reverse lifting role on the nut body 3, so that the nut body 3 can be removed from the inside of the fixing groove 2, thereby improving the disassembly efficiency of the self-clinching nut assembly and reducing the labor intensity of the staff.

[0026] Example 2: Figure 2-Figure 5 As shown, the outer wall of the nut body 3 is provided with embossed teeth 6, and an elastic gasket 7 is provided on one side of the outer wall of the nut body 3, and the elastic gasket 7 is arranged on the outer wall of the embossed teeth 6. The outer wall of the nut body 3 is provided with two threaded grooves 12, and the inner walls of the two threaded grooves 12 are movably inserted with threaded rods 13, and the outer walls of the two threaded rods 13 are movably connected with mounting plates 14, and the outer wall sides of the two mounting plates 14 are fixedly installed with rubber pads 15, and one side of the outer wall of the rubber pads 15 is in contact with the outer wall of the bolt 4, and the outer wall of the nut body 3 is fixed with two mounting boxes 16, and the inner walls of the two mounting boxes 16 are movably embedded with movable blocks 17, and the tops of the two movable blocks 17 are provided with insertion grooves 18, and the inner walls of the two insertion grooves 18 are movably inserted with limit rods 19, and the inner walls of the two movable blocks 17 are provided with two magnets 20.

[0027] The effect achieved by the entire embodiment 2 is that when it is necessary to fix the plate or sheet metal fixedly connected using the pressure rivet nut assembly, the nut body 3 is first fixed under the action of the extrusion device, and under the action of the elastic gasket 7, the friction between the nut body 3 and the sheet metal can be increased, and then the bolt 4 and the nut body 3 are tightened by threaded connection, thereby completing the fixed connection of the sheet metal, and then under the operation of the staff, the threaded rod 13 inside the threaded groove 12 is rotated to drive the mounting plate 14 and the rubber pad 15 to move toward the middle, so that the rubber pad 15 has an extrusion effect on the bolt 4, thereby increasing the friction between the bolt 4 and the rubber pad 15, and avoiding the bolt 4 from loosening during use and affecting the fixing effect, and then the movable block 17 inside the mounting box 16 is moved to the appropriate position, and the limiting rod 19 is inserted into the notch opened in the insertion groove 18 and the outer wall of the threaded rod 13, and at the same time, under the action of the magnet 20, the limiting rod 19 is fixed, thereby playing a role in fixing and limiting the threaded rod 13, further avoiding the bolt 4 from loosening during use, greatly improving its practicality.

[0028] Working principle: During use, when it is necessary to fix the plate or sheet metal that is fixedly connected using the rivet nut assembly, first, under the action of the extrusion device, press the nut body 3 into the inside of the fixing groove 2 to fix the nut body 3, and then put the second thin plate 5 onto the outer wall of the bolt 4, and tighten the bolt 4 and the nut body 3 through threaded connection, thereby completing the fixed connection between the first thin plate 1 and the second thin plate 5, and then, under the operation of the staff, rotate the threaded rod 13 inside the threaded groove 12 to drive the mounting plate 14 and the rubber pad 15 to move toward the middle, so that the rubber pad 15 squeezes the bolt 4, thereby increasing the friction between the bolt 4 and the rubber pad 15 to prevent the bolt 4 from loosening during use, and then move the movable block 17 inside the mounting box 16 to the appropriate position, and insert the limiting rod 19 into the insertion groove 18 and the notch opened in the outer wall of the threaded rod 13, thereby When the first and second plates 1 and 5 need to be removed, the limiting rod 19 is removed from the insertion groove 18, and then the threaded rod 13 is rotated to drive the mounting plate 14 and the rubber pad 15 to move outward. Then, under the operation of the staff, the bolt 4 is rotated to remove it from the inside of the nut body 3, so that the bolt 4 no longer has a fixing effect on the first and second plates 1, so that it can be easily removed. Then, the nut body 3 needs to be removed from the inside of the fixing groove 2. Under the operation of the staff, one end of the push rod 11 fixedly inserted in the movable plate 10 is pressed, so that the movable plate 10 moves toward the side of the first thin plate 1 in the embedding groove 9, thereby driving the other end of the push rod 11 to contact the first thin plate 1. During the continuous pressing process, the push rod 11 will play a reverse lifting role on the nut body 3, so that the nut body 3 can be removed from the inside of the fixing groove 2, completing the disassembly of the rivet nut assembly.
