Description

Technical Field

[0001] The utility model relates to the technical field of press riveting nuts, in particular to a general-purpose press riveting nut. Background Technique

[0002] A press riveting nut is a fastener specifically used for thin plate connection and is also called a press riveting part. Its working principle is that during the riveting process, the matrix material at the press riveting part undergoes plastic deformation under external pressure and then is extruded into a special prefabricated groove in the riveting nut structure, thereby realizing the reliable connection of two parts.

[0003] The utility model patent application document with the publication number of "CN219242408U" discloses a general-purpose press riveting nut, including a nut body. The key lies in that: a central hole penetrates through the nut body, and a ring-shaped convex platform is arranged at any orifice of the central hole. A circle of knurling teeth is arranged outside the ring-shaped convex platform, and the nut body is an N-sided body, where N≥3. Compared with the prior art, the general-purpose press riveting nut provided by the utility model is fastened to the plate to be assembled through the knurling teeth, and the plate to be assembled is clamped through the taper angle at the outer end of the ring-shaped convex platform, further improving the fastening degree of the press riveting nut. There is no need to adjust the height of the nut head to adapt to the thickness of the plate. By setting a polyhedron structure, it can be avoided that the nut rotates in reverse when the bolt rotates out due to reverse torsion, resulting in the situation where it cannot be fixed. The structure is novel and suitable for plates with different thicknesses.

[0004] The above-mentioned disclosed general-purpose press riveting nut has the following defects: The technical solution has a relatively low anti-torsion ability when fastening with the external assembly plate through the knurling teeth, resulting in an easy falling-off situation.

[0005] It can be seen from this that the existing general-purpose press riveting nut equipment does not have a good anti-torsion structure, and it is necessary to improve the existing deficiencies to provide a general-purpose press riveting nut. Content of the Utility Model

[0006] The purpose of the utility model is to provide a general-purpose press riveting nut to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a general-purpose press riveting nut, including a press riveting nut body. A threaded installation groove is opened on the outer surface of the press riveting nut body, and several groups of anti-torsion components are arranged on the lower surface of the press riveting nut body;

[0009] The installation holes are pre - drilled in the external connection plate by a punching machine. Then, the body of the press - riveting nut and multiple anti - torsion components are aligned close to the inside of the pre - drilled installation holes, and then placed under a pressing machine. By pressing the body of the press - riveting nut, the first fixing column and the second fixing column squeeze the circular ring shell, so that the circular ring shell expands and presses against the external installation plate. Through the arrangement of multiple through - slots, it is convenient for the circular ring shell to expand more evenly. Through the arrangement of anti - slip strips, when the circular ring shell expands and squeezes and fixes the external connection plate, the anti - slip strips can further increase the anti - torsion ability. Generally speaking, the anti - torsion ability is relatively improved, and the problem of easy detachment is avoided.

[0010] Further, the anti - torsion component includes a first fixing column, a circular ring shell, a second fixing column, anti - slip strips and through - slots. The first fixing column is fixedly installed on the lower surface of the body of the press - riveting nut. The circular ring shell is fixedly installed on the lower surface of the first fixing column. The second fixing column is fixedly installed on the lower surface of the circular ring shell.

[0011] Further, several anti - slip strips are fixedly installed on the outer surface of the circular ring shell, and several through - slots are formed on the outer surface of the circular ring shell.

[0012] Further, an annular boss is fixedly installed on the lower surface of the body of the press - riveting nut.

[0013] Further, an external chamfer is formed on the outer surface of the annular boss.

[0014] Further, an internal chamfer is formed on the inner surface of the annular boss.

[0015] The utility model has the following beneficial effects:

[0016] (1) In the utility model, the installation holes are pre - drilled in the external connection plate by a punching machine. Then, the body of the press - riveting nut and multiple anti - torsion components are aligned close to the inside of the pre - drilled installation holes, and then placed under a pressing machine. By pressing the body of the press - riveting nut, the first fixing column and the second fixing column squeeze the circular ring shell, so that the circular ring shell expands and presses against the external installation plate. Through the arrangement of multiple through - slots, it is convenient for the circular ring shell to expand more evenly. Through the arrangement of anti - slip strips, when the circular ring shell expands and squeezes and fixes the external connection plate, the anti - slip strips can further increase the anti - torsion ability. Generally speaking, the anti - torsion ability is relatively improved, and the problem of easy detachment is avoided.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above - mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
