Automobile windshield repair device

Abstract

The invention discloses an automobile windshield repairing device. The automobile windshield repairing device comprises a heating tube, a glue injection tube, a shell, a sleeve and an end cap. The head of the shell is tapered, a cavity is formed in the shell, an opening is formed in the end face of the tail of the shell, and a first circular hole is formed in the end face of the head of the shell. The end cap is inserted into the opening of the tail of the shell and is matched with the tail of the shell. The heating tube is located in the cavity of the shell. The two ends of the heating tube are correspondingly fixedly embedded into the end cap and a circular groove in the head of the shell. A second circular hole is formed in the middle of the end cap and is coaxial with the first circular hole. A limiting piece is arranged in a circular ring at the tail of the sleeve. The glue injection tube passes the circular ring at the tail of the sleeve and extends into the circular tube at the head of the sleeve. The glue injection pipe is limited to moving in the circular ring at the tail of the sleeve through the limiting piece. The automobile windshield repairing device is concise in structure and convenient to operate, and the repairing effect of glue on glass is improved; and the circular tube of the head of the sleeve abuts against the glass to be repaired, due to the fact that a spring is arranged at the tail of the sleeve, stress can be buffered through the spring, and secondary stress on the glass is avoided.

Description

technical field [0001] The invention belongs to the technical field of auto parts repair, and relates to an auto windshield repair device. Background technique [0002] In the process of repairing the cracked car windshield, the car maintenance personnel need to inject glue into the crack of the windshield, so as to complete the repair work of the crack of the windshield. Automobile maintenance personnel often use a piston device to inject glue. The piston device in the prior art includes a piston rod, a piston sleeve and a sealing ring. The sealing ring is fixedly connected to the piston rod and is located at the front end of the piston rod. The piston The dynamic sealing is realized by the sealing ring between the rod and the piston sleeve. When repairing the glass, the staff first use the piston device to extract a small amount of glue, and then push the piston to inject the glue into the crack of the glass. [0003] The piston rod and the piston sleeve in the prior art...

AI Technical Summary

Problems solved by technology

[0003] The piston rod and the piston sleeve in the prior art piston device are in the process of reciprocating relative movement, the piston rod and the piston sleeve are always in a completely sealed state, and the staff must control the push of the piston rod during the injection process. It is necessary to fully inject the glue into the crack and prevent the air in the piston sleeve from being injected into the crack. If the piston rod is pushed too far, the air in the piston sleeve will be compressed again. Into the glass cracks, which will expand the glass cracks and cause secondary damage to the car windshield, and because the amount of glue injected in the repair work is very small, it is difficult for the staff to grasp the extent of the piston rod
