Description

Technical Field

[0001] The utility model relates to the field of rivets that are not easily broken, in particular to a rivet that is not easily broken. Background Technique

[0002] A rivet is a fastener used to connect two or more materials. It usually consists of a head and a shank. The head has an annular flange, and the shank is cylindrical. During installation, the rivet is inserted into a pre-drilled hole, and then the head is deformed by a tool to make it tightly connected to the material surface.

[0003] When the existing rivets are in use, the force on the nail cap is uneven, resulting in easy deformation and fracture during extrusion. Secondly, the connection between the opened nail cap and the rivet head is relatively weak, and most rivets do not have a reinforcement function, which affects the service life of the rivets. Therefore, the utility model provides a rivet that is not easily broken to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a rivet that is not easily broken is proposed. When the device is in use, by pulling the process rod of the rivet, multiple second fixing blocks move downward, so that multiple second triangular fixing blocks fixedly arranged at the lower end extrude the first triangular fixing blocks, causing the cylindrical blocks fixedly arranged at one end of the multiple first triangular fixing blocks to move outwards. The cylindrical heads fixedly arranged at one end of the multiple cylindrical blocks add multiple stress points to the inside of the nail cap, enabling the nail cap to open evenly and avoiding fracture caused by uneven stress during extrusion. The fixing piece fixedly arranged at the inner end moves downward along with the rivet body, so that the fixing piece can be conveyed to the middle of the nail cap during extrusion along with the slot, playing a reinforcing role.
