Embodiment Construction

[0048] In order to have a clearer understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0049] like figure 1 , figure 2 , Figure 19 and Figure 20 As shown, the self-drilling rivet of the embodiment of the present invention includes:

[0050] The drill bit 1 is used to drill into the wall body 9 of the object to be drilled. The object to be drilled can be a wall body, a door body, a plate-shaped body, etc. The material of the drill bit 1 is, for example, an alloy steel and other hard materials suitable for drilling and cutting, As a preferred option, the drill bit is disposable, and the drill bit can be drilled into the cutting iron plate so as to install doors and windows, one end of the drill bit is the drilling end 11, and the other end of the drill bit is the connection end 13 of the drill bit; like image 3 and Fi...

Abstract

The invention provides a self-drilling pulling rivet. The self-drilling pulling rivet comprises a drill bit, a screw, a nut and an expand tube. A screw cap and a screw clamping portion are located at the first end and the second end of a screw rod respectively, and the screw clamping portion is connected to the connection end of the drill bit in a clamped manner; the nut is connected with the second end of the screw rod through threads and located between the connection end of the drill bit and the screw cap; the outer wall of the nut is provided with multiple sliding grooves which are arranged at intervals; the expand tube is arranged on the screw rod in a sleeving manner and located between the nut and the screw cap; the first end of the expand tube is close to the screw cap, and the second end of the expand tube serves as an expansion end and is close to the nut; and the expand tube comprises multiple long-strip-shaped side walls which are arranged at intervals, and an opening is formed in the portion, among the multiple long-strip-shaped side walls, at the second end of the expanding end; and the long-strip-shaped side walls can slide in the corresponding sliding grooves. By means of the self-drilling pulling rivet, the operating time is shortened, the operating efficiency is improved, and the operating tools are reduced.

Description

technical field [0001] The invention relates to a pull rivet, in particular to a self-drilling pull rivet capable of drilling an installation hole by itself. Background technique [0002] In the existing rivets, the installation holes are first drilled with a drilling tool, then the rivets are placed in the installation holes, and finally the rivets are acted on by a rivet gun, and the rivets are deformed by force, and the rivets are deformed and expanded. Then, a disc-shaped or cylindrical card table is formed and clamped in the installation hole to complete the riveting connection. In this way, the deformation and expansion processes of punching and pulling rivets are two independent processes, and different tools are required for the deformation and expansion processes of punching and pulling rivets, which increases operation time and reduces operation efficiency. SUMMARY OF THE INVENTION [0003] The present invention provides a self-drilling rivet to solve the proble...
