Description

Technical Field

[0001] The utility model relates to the technical field of rivets, in particular to a combined rivet. Background Art

[0002] A rivet is a mechanical connector that is usually used to fix two or more workpieces together to form a permanent connection. It consists of a main body and a head for fixing. Rivets are usually used to connect various materials such as metal, plastic, wood, etc. The working principle of rivets is to use deformation to fix the workpieces together. When installing rivets, first drill holes in the workpieces to be connected, and then insert the main body of the rivet into the hole. Next, a hammer or pressure tool is used to apply force to one end of the rivet so that the main body of the rivet forms a head at the other end, and an expansion part is formed between the head and the workpiece, so that the two workpieces can be fixed together. The head of the rivet usually has different shapes to adapt to different installation methods and applications. Common rivet head shapes include round head, flat head, semi-circular head, etc. Rivets have the advantages of simple structure, easy installation, low cost, and strong connection, so they are widely used in machinery manufacturing, aerospace, automobile manufacturing, construction and other fields.

[0003] Combined rivets have the advantages of high strength, wide applicability, high production efficiency, and beautiful appearance. Therefore, they are widely used in various engineering and manufacturing fields, and thus a combined rivet is used.

[0004] In the conventional technology, the main body and the fixed head of the combined rivet may fall off during connection, resulting in a poor fixing effect. Utility Model Content

[0025] Reference Figure 2 , one end of the second fixing plate 8 is fixedly connected to a clamping column 9; a first storage groove 10 is provided inside the third hollow column 7, and a second storage groove 11 is provided inside the third hollow column 7; a spring 13 is provided inside the third hollow column 7, one end of the spring 13 is fixedly connected to the inner wall of the second storage groove 11, and the other end of the spring 13 is fixedly connected to a clamping bead 12; the outer wall of the clamping column 9 is slidably connected to the inner wall of the first storage groove 10;

[0027] Working principle: When the rivet is needed, first, the second hollow column 5 needs to be slid to the inner wall of the third hollow column 7 through the fixing plate 6, and then the sliding column 1 can be pulled out from the inside of the second hollow column 5 through the riveting machine. When the sliding column 1 is pulled out, the first fixing plate 3 can be driven to slide through the connecting cone 2. When the first fixing plate 3 slides, it will squeeze the first hollow column 4, but due to the shape of the connecting cone 2, it will be separated from the first fixing plate 3, so that the first fixing plate 3 and the first hollow column 4 are pulled into sheets, and the sliding column 1 and the connecting cone 2 are separated from the inner wall of the second hollow column 5. At this time, the first fixing plate 3 and the first hollow column 4 will produce a shape on the inner wall of the second hollow column 5 and expand the middle of the second hollow column 5, so that the inner and outer walls of the second hollow column 5 can be stuck on the inner wall of the third hollow column 7, so that the rivet is stuck. The second fixing plate 8 can drive the card column 9 to slide on the inner wall of the first storage groove 10 by pulling the second fixing plate 8. When the card column 9 slides, the spring 13 is squeezed. When the spring 13 is squeezed, the card bead 12 on the inner wall of the second storage groove 11 is squeezed, so that the second fixing plate 8 can be quickly disassembled for easy replacement. Then, the main structure sliding column 1, connecting cone 2, first fixing plate 3, first hollow column 4, second hollow column 5, fixing plate 6, third hollow column 7, and second fixing plate 8 are simple and the raw materials are cheap, so as to achieve the effect of reducing costs. The device can not only achieve the effect of jamming the inner and outer walls of the second hollow column 5 on the inner wall of the third hollow column 7 to jam the rivet, but also achieve the effect of quickly disassembling the second fixing plate 8 for easy replacement, and can also achieve the effect of reducing costs.
