Caulking gun with replaceable mouth for building construction

Abstract

The invention discloses a caulking gun with a replaceable nozzle part for building construction. The caulking gun comprises a glue tube, a piston which is arranged in the glue tube and a drive device which is connected with the piston, wherein one end of the glue tube is provided with a glue nozzle, the other end of the glue tube is fixedly connected with the drive device, the drive device is connected with the piston through a piston rod, the drive device comprises a shell and a motor and a drive roller which are arranged in the shell, the piston rod is provided with a guide groove extending in the axial direction, a fixed plate which is matched with the guide groove is also arranged in the shell, the fixed plate is arranged in the guide groove, and the glue nozzle is connected to the glue tube in a threaded way. The caulking gun has beneficial effects that the glue nozzle is connected with the glue tube in a threaded way, so that the damaged glue nozzle can be conveniently replaced; a glue outlet end of the glue nozzle can be connected with a sharp suction pipe in a threaded way, thus the sharp suction pipe can penetrate into a glue bag to suck the glue, and convenience can be achieved; the piston rod is provided with the guide groove, and the fixed plate is clamped into the guide groove, so that the follow-up rotation of the piston rod can be prevented.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a glue gun with a replaceable mouth for building construction. Background technique [0002] The caulking gun is a bonding and sealing caulking and gluing tool, which is widely used in architectural decoration, electronic appliances, automobiles and auto parts, ships and containers and other industries. [0003] Most of the existing glue guns are used to pull the trigger and push the push rod. The spring force is used to return the trigger, so pulling the trigger needs to overcome the spring force, and pushing the push rod also requires a lot of strength. After using some gluing machines for a long time, the fingers of the staff are very sore, and it is difficult to continue working, resulting in low work efficiency. Moreover, the glue nozzles on the existing gluing guns are fixed on the glue cylinder, and need to be repaired after damage. It is very costly to replace the gl...
