The side of the press-fit head is provided with full toothed patterns.

[0005] In some embodiments, the riveting head, annular extrusion groove, limiting block one, rivet rod and limiting block two are an integral structure.

[0006] In some embodiments, the width of the annular extrusion groove and the length of the rivet are preset lengths.

[0007] In some embodiments, the serrations are triangular teeth with two planar surfaces.

[0008] In some embodiments, the tips of the triangular teeth of the flower pattern are set as arcs.

[0010] 1. Adapts to different plate thickness selection requirements;

[0011] 2. Resolve the inherent structural defects of the dents on the surface;

[0012] 3. The toothed structure greatly improves the firmness of the riveting and significantly reduces the risk of loosening during the use of the clamps;

[0013] 4. Changing the riveting direction reduces the difficulty of riveting, improves efficiency, and reduces processing costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a toothed press-fit positioning pin, including a press-fit structure 1 and a press-fit structure 2 connected to each other. The press-fit structure 1 includes a press-fit head 3 and a limiting block 4 connected to each other. An annular extrusion groove 5 is provided between the press-fit head 3 and the limiting block. The press-fit structure 2 includes a rivet rod 6 connected to the limiting block 4 and a limiting block 7. One end of the rivet rod 6 is connected to the center of the end face of the limiting block 4 away from the press-fit head 3, and the other end of the rivet rod 6 is connected to the center of the end face of the limiting block 7.

[0022] The 8-tooth structure on the rivet head 3 greatly improves the rivet's firmness and significantly reduces the risk of loosening during use. At the same time, the full 8-tooth structure on the side ensures that the rivet screw achieves a completely countersunk effect during use.

[0023] The riveting head 3, the annular extrusion groove 5, the first limiting block 4, the rivet rod 6, and the second limiting block 7 are an integral structure.

[0024] By setting up riveting structure 1 and riveting structure 2, it is possible to rivet two plates of different thicknesses together, adapting to different plate thickness selection requirements; at the same time, step-by-step riveting connection can reduce the riveting force and solve the inherent structural defects of appearance pits; changing the riveting direction reduces the riveting difficulty, improves efficiency, and reduces processing costs.

[0025] The width of the annular extrusion groove 5 and the length of the rivet rod 6 are preset lengths. According to the actual product requirements, annular extrusion grooves 5 of different widths and rivet rods 6 of different lengths are processed to adapt to the selection requirements of different plate thicknesses.

[0026] The side of the rivet head 3 is provided with a full set of serrations 8.

[0027] The serration 8 is a triangular tooth shape on two flat surfaces. The triangular tooth shape 8 can improve the firmness of the riveting and greatly reduce the risk of loosening during the use of the clamp.

[0028] The tips of the triangular teeth of the flower teeth 8 are set as arcs. The arc design can avoid the triangular teeth being too sharp and causing damage to the board or workers.

[0029] The toothed 8-pinch positioning pin of this application is made of carbon steel electroplating and aluminum alloy, which can increase the types of pin materials and facilitate cost control.

[0030] Through the technical solution of this application, the 8-tooth riveting positioning pin effectively solves the problem of poor appearance in thin plate riveting:

[0031] 1. Adapts to the design needs of the sheet metal industry; can be selected arbitrarily according to the sheet thickness.

[0032] 2. Greatly reduces or eliminates the difficulty of surface treatment of products after riveting;

[0033] 3. The extrusion trough structure was modified to improve its anti-loosening performance;

[0034] 4. Change the riveting method to reduce riveting difficulty, improve efficiency, and reduce processing costs;

[0035] 5. Increase the types of materials for the locking posts to facilitate cost control (carbon steel electroplating and aluminum alloy have relatively lower costs).

[0036] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
