Gun-barrel-length-adjustable grease gun for car overhaul

Abstract

The invention relates to the technical field of car overhaul, in particular to a gun-barrel-length-adjustable grease gun for car overhaul. The grease gun comprises a gun head, a grease cylinder and a pull rod; the gun head is in sealing connection with the grease cylinder through a grease inlet sealing cover; a plunger is fixedly mounted on the upper end face of the gun head; a connecting piece is fixedly arranged on the outer end face of the gun head, and a connecting rod is hinged to the outer end of the connecting piece; a grease outlet of the gun head is in sealing connection with a grease outlet pipe, and a grease outlet valve is fixedly mounted on the outer end face of the grease outlet pipe; a telescopic pipe is mounted on the inner end face of the grease cylinder, and a grease storing cavity is formed in the telescopic pipe; a sleeve is slidably connected to the outer end face of the grease cylinder, and the outer end face of the sleeve is in sealing connection with a sealing plug; the pull rod is slidably connected into the sealing plug; one end of the pull rod is fixedly connected with a leather cup, and the other end of the pull rod is fixedly connected with a handle; a spring is slidably connected to the outer end face of the pull rod; and a graduation ruler is fixedly mounted on the outer end face of the sleeve. The gun-barrel-length-adjustable grease gun for car overhaul is scientific in structure, reasonable in design, convenient to use and high in practicability.

Description

technical field [0001] The invention relates to the technical field of automobile maintenance, in particular to a grease gun for automobile maintenance with an adjustable barrel length. Background technique [0002] The grease gun is a manual tool for adding grease to mechanical equipment; it can be equipped with an iron gun rod or a hose for refueling.

Problems solved by technology

[0003] Automobile inspection is an inspection to determine the technical status or working ability of the automobile. During the use of the automobile, with the prolongation of the use time, its parts are gradually worn, corroded, deformed, aged, and the lubricating oil deteriorates, etc., resulting in a larger gap between the mating pairs , cause movement looseness, vibration, sound and air leakage, water leakage, oil leakage, etc., resulting in a decline in the technical performance of the car. The core of car maintenance work is to maintain the technical condition of the car in good condition. Grease guns are often used in car inspections. Oil injection treatment, but because there are many parts and complex shapes of the car, during the oil injection process, the oil injection is often not in place due to the insufficient length of the barrel, and the oil storage capacity of the barrel is small, and it needs to be disassembled frequently for refueling operations, which affects the inspection of the car. quality and efficiency, so a new practical device is needed to solve these problems
