Vertical safety type nozzle mechanism based on air nailer

Abstract

The invention relates to the technical field of building decoration tools, and discloses a vertical safety type nozzle mechanism based on an air nailer. The mechanism comprises a nozzle shell, a nozzle air core is fixedly sleeved with the nozzle shell, a nail arranging interface is arranged at the bottom of one side of the outer part of the nozzle shell, and a mounting disc is fixedly arranged atthe top end of the nozzle air core. Three sets of safety sliding grooves are evenly formed in the outer surface of the nozzle air core, and the tops of the inner walls of the three sets of safety sliding grooves are each provided with a set of fixing blocks. According to the vertical safety type nozzle mechanism based on the air nailer, a sealing lock cylinder and the structure on the sealing lockcylinder are arranged so that a linkage interlocking mechanism can be formed between the sealing lock cylinder and the three sets of sliding connecting rods, and only when the three sets of sliding connecting rods are all triggered, an air flow pipeline can be connected, and high-pressure air flow can impact nails to be ejected out; and therefore, the triggering difficulty of a safety mechanism of the air nailer is increased, and the problem that the air nailer is mistakenly triggered in a complex working environment to cause fire to injure people is solved.

Description

technical field [0001] The invention relates to the technical field of building decoration tools, in particular to a vertical safety nozzle mechanism based on an air nail gun. Background technique [0002] The air nail gun is a building decoration tool that uses high-pressure gas to drive the firing pin to perform a hammering movement to shoot out the row of nails at a certain initial speed. Compared with the original method of nailing nails into the sheet by hammering, It greatly reduces the workload and labor intensity of people, and at the same time, the efficiency is extremely high and it will not cause damage to the surface of plates and other plates, so that it has high aesthetics. [0003] Moreover, because the initial velocity of the nails ejected by the air nail gun is relatively large, the impact force at close range is relatively large and the damage is strong. The nozzle of the nail gun must be equipped with a safety frame, and the air nail gun can only be trigg...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a vertical safety nozzle mechanism based on an air nail gun, which has high requirements for safety triggering, does not cause false triggering to injure others or itself, and can always keep the distance between the nozzle and the sheet. The advantages of the vertical relationship and the fact that the nails will not be tilted or even fly out solve the problem that the triggering conditions of the existing safety frame structure are relatively simple, as long as it is squeezed, it will be triggered, so that it can be used in a complex working environment in practice. It will still occur that the air nail gun fires and hurts others or yourself, and in order to ensure that it will not fly out through the sheet, it is necessary to keep the nozzle of the air nail gun perpendicular to the sheet when using the air nail gun, but in actual operation During the process, it is very difficult to maintain the vertical relationship between the nozzle and the sheet, and the nails that are injected will often appear tilted and exposed, or even fly out.
