[0002] Riveted nuts, also known as pull rivet nuts, rivet nuts, etc., are a type of nut used on thin plates or sheet metals. They are usually composed of a nut body and a deformed part at the tail. When installing the rivet nut, place it in a hole pre-drilled in the plate, and then use a rivet gun or other tools to pull rivets on the tail. It is mainly used in sheet metal processing, automobile manufacturing, mechanical equipment manufacturing, etc. It is easy to install, firm and reliable, beautiful and practical. The use of special-shaped cylindrical rivet nuts can better fit the plate, adapt to specific installation environments, improve production efficiency and reduce costs, and meet specific design requirements. Traditional special-shaped cylindrical rivet nuts have high installation requirements, are prone to stress concentration, have limited corrosion resistance, limited load-bearing capacity, and relatively high costs.

[0023] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment of a special-shaped cylindrical rivet nut, comprising a deformable outer cylinder 1, an inner wall of the deformable outer cylinder 1 is provided with a positioning groove 2, the inner wall of the positioning groove 2 is fixedly connected with a rotating shaft 3, the outer wall of the rotating shaft 3 is rotatably connected with a rotating block 4, the outer wall of the rotating block 4 is fixedly connected with a limiting block 5, the inner wall of the deformable outer cylinder 1 is provided with a limiting groove 6, the outer wall of the limiting block 5 is slidably connected to the inner wall of the limiting groove 6, the inner wall of the deformable outer cylinder 1 is provided with a sliding groove 7, the inner wall of the deformable outer cylinder 1 is provided with a first threaded groove 8, the upper surface of the deformable outer cylinder 1 is provided with a fixing assembly, the fixing assembly is used to fix a first plate 9 and a second plate 11; the fixing assembly includes a first plate 9, the lower surface of the first plate 9 is slidably connected with the first plate 9, the inner wall of the first plate 9 is slidably connected to the outer wall of the deformable outer cylinder 1, the inner wall of the deformable outer cylinder 1 is threadedly connected with a bolt 10, the outer wall of the bolt 10 is threadedly connected to the inner wall of the first threaded groove 8, and the lower surface of the bolt 10 is slidably connected with the second plate 11;

[0025] Specifically, the rotating shaft 3 is fixed in the positioning groove 2 in the deformable outer cylinder 1. When the bolt 10 rotates in the inner wall of the deformable outer cylinder 1, the bolt 10 pushes the rotating block 4 to rotate on the outer wall of the rotating shaft 3, so that the limit block 5 is stuck in the limit groove 6 in the inner wall of another deformable outer cylinder 1. The sliding groove 7 and the first thread groove 8 opened on the inner wall of the deformable outer cylinder 1 are used to limit the position of the special-shaped nut 12 and the connecting bolt 10, which can fix the first plate 9 and the second plate 11, so that the device can achieve the effect of extending the special-shaped riveted nut to be suitable for plates of different thicknesses.

[0026] Reference Figure 1 and Figure 2The lower surface of the second plate 11 is slidably connected to a special-shaped nut 12, and the lower surface of the special-shaped nut 12 is slidably connected to the upper surface of the deformed outer cylinder 1; the outer wall of the special-shaped nut 12 is fixedly connected to a slider 13, and the outer wall of the slider 13 is slidably connected to the inner wall of the slide groove 7; the inner wall of the special-shaped nut 12 is slidably connected to a fixed ball 14;

[0027] Specifically, a slider 13 is fixed to the outer wall of the special-shaped nut 12 under the second plate 11. The special-shaped nut 12 is inserted into the deformable outer cylinder 1, and the slider 13 is inserted into the slide groove 7 to limit the position of the special-shaped nut 12 in the deformable outer cylinder 1. When the bolt 10 rotates in the first thread groove 8, the bolt 10 pushes the fixing ball 14 to clamp the fixing ball 14 into the limiting groove 6 in the deformable outer cylinder 1, thereby achieving the effect of quickly installing the special-shaped riveted nut.

[0028] Reference Figure 2 and Figure 3 The outer wall of the fixed ball 14 is slidably connected to the inner wall of the limiting groove 6; the inner wall of the special-shaped nut 12 is provided with a second thread groove 15; the outer wall of the second thread groove 15 is threadedly connected to the outer wall of the bolt 10;

[0029] Specifically, after the bolt 10 is screwed out of the deformable outer cylinder 1, the fixing ball 14 will be separated from the limiting groove 6, so that the special-shaped nut 12 can leave the inner wall of the deformable outer cylinder 1, thereby achieving the effect of quickly disassembling the special-shaped riveted nut.

[0030] Working principle: When the rivet nut is needed and the plate to be fixed is thicker, the rivet nut is lengthened by inserting one deformable outer cylinder 1 into the inner wall of another deformable outer cylinder 1. When the rotating bolt 10 is threadedly connected to the inner wall of the first thread groove 8, the bolt 10 can push the rotating block 4 to rotate on the outer wall of the rotating shaft 3 so that the limiting block 5 is stuck in the inner wall of the limiting groove 6 opened on the inner wall of the deformable outer cylinder 1, so that the two deformable outer cylinders 1 are fixed, so that the rivet nut growth can be suitable for plates of different thicknesses, and the slider 13 on the special-shaped nut 12 is stuck in the slide groove 7 opened on the inner wall of the deformable outer cylinder 1 to locate the position of the special-shaped nut 12. When the bolt 10 rotates in the second thread groove 15 on the inner wall of the special-shaped nut 12, the bolt 10 can push the fixing ball 14 in the special-shaped nut 12 and make it fit into the inner wall of the limiting groove 6 in the deformable outer cylinder 1, so that the special-shaped rivet nut is fixedly connected to the two plates. When disassembly is required, the bolt 10 is unscrewed, the fixing ball 14 is separated from the inner wall of the limiting groove 6, and the special-shaped nut 12 is pulled outward to separate it from the inner wall of the deformable outer cylinder 1, thereby achieving the purpose of quickly disassembling the special-shaped rivet nut. This part not only solves the problem that the fixed size of traditional rivet nuts limits their application on plates of different thicknesses and lacks flexibility. When facing some plates of special thickness, it may be impossible to find a suitable rivet nut, affecting the smooth progress of the project, but also solves the problem of cumbersome steps in disassembling traditional nuts.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
