Pneumatic hand riveter

Abstract

The invention discloses a pneumatic hand riveter which comprises a hand riveter body, a handle and an air inlet tube, wherein the outer surface of the lower end of the hand riveter body is fixedly connected with the handle, the outer surface of the lower end of the handle is fixedly connected with the air inlet tube, a transmission cavity is formed in the handle and is of an L-shaped structural design, and an insertion plate is movably connected into the transmission cavity; the insertion plate penetrates through the handle, a ventilation opening is formed in the outer surface of the upper end of the insertion plate, a transmission rod is hinged to the outer surface of the rear end of the insertion plate, a blocking plate is hinged to the other end of the transmission rod, and the blocking plate is also located in the transmission cavity, so that the riveting efficiency is greatly improved; when the user does not press the insertion plate, the insertion plate moves forwards under the action of a telescopic spring and blocks gas in the movable cavity, at the moment, the blocking plate is pulled by the insertion plate through the transmission rod, the blocking plate moves downwards to open a gas release opening, the gas in the movable cavity is discharged through the gas release opening, and the push rod is reset after being extruded by a reset spring.

Description

technical field [0001] The invention relates to the technical field of riveting guns, in particular to a pneumatic riveting gun. Background technique [0002] Rivet guns are used for fastening and riveting of various types of metal sheets, pipes and other manufacturing industries. At present, they are widely used in the riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. . Developed to solve the shortcomings of metal sheets and thin tubes that weld nuts are easy to melt, and tapping internal threads is easy to slip. It can rivet riveting products that do not require internal thread tapping or welding nuts. The riveting is firm and efficient, and it is convenient and quick to use; [0003] 1. When decorating the interior, when using a rivet gun to fix the wall plate, since most of the rivet guns are manual scissors, this causes the user to manually squ...

AI Technical Summary

Problems solved by technology

[0003] 1. When decorating the interior, when using a rivet gun to fix the wall plate, since most of the rivet guns are manual scissors, this causes the user to manually squeeze the rivet gun when riveting the rivet and the plate Only the riveting gun can complete the riveting, which is time-consuming and inefficient; 2. When riveting rivets with different diameters, the user needs to use a wrench to replace the gun head with a matching diameter. The whole replacement process is more cumbersome and affects Work efficiency, and the user needs to wear multiple gun heads when working, which is mostly inconvenient to carry
