Problems solved by technology

Manual grease guns and 12V light electric grease guns are widely used. Manual grease guns are simple in structure and low in price, but manual grease guns are driven by manpower, which has fatal shortcomings such as laborious, slow oil filling, and unable to increase pressure. Light electric grease guns still cannot Adapt to the professional market that requires high pressure and large flow
[0003] Steven W. Post and William T. invented an electric grease gun (U.S.P6,315,327) consisting of a frame, a three-stage planetary gear reduction, a crank slider, a plunger, a switch, an oil supply system and a safety valve, but Its maximum output pressure is 6000pis, and the volume is large, and the operation is still inconvenient

Embodiment Construction

[0051] The following examples will help to understand the present invention, but are not limited to the content of the present invention:

[0052] by attaching Figure 1-6Visible, grease gun is mainly made of frame 13, left casing 1 and right casing 2, plunger pump, crank slider, gear reduction, supply system, switch, safety mechanism.

[0053] The plunger pump has an inner hole specially processed on the frame 13, the plunger 7 is placed in the hole, and the check valve 8 is assembled at the front end of the hole. Through the reciprocating motion of the plunger 7 and the one-way conduction characteristic of the check valve, the Imported oil 22 sucks butter and is pushed out by outlet 23 under high pressure.

[0054] The safety valve at the end of frame 13 is composed of valve body, sealing steel ball 50, butterfly spring 34, butterfly positioning mandrel, copper sleeve 60 and red copper sheet 49 are applied at both ends respectively to prevent oil leakage, and hexagonal bolt...

Abstract

The present invention relates to grease gun, and is especially one kind of electrically driven 18 V DC heavy grease gun. It has plug-in battery package to provide DC power source to drive great power DC motor, three stage planetary gear and straight gear for reducing speed to increase the output torque of the motor, and sliding crank mechanism to convert the rotation of motor to the linear reciprocation of block and drive the reciprocating plunger to complete high pressure grease injection via cooperation with the grease supplying system. The present invention has high pressure, great flow rate and other advantages.

Description

technical field [0001] The invention relates to an oiling tool, which is an 18V DC heavy-duty grease gun. Background technique: [0002] The grease gun is a convenient and fast oiling tool used in automobiles, agricultural machinery, construction machinery, and other industries. Manual grease guns and 12V light electric grease guns are widely used. Manual grease guns are simple in structure and low in price, but manual grease guns are driven by manpower, which has fatal shortcomings such as laborious, slow oil filling, and unable to increase pressure. Light electric grease guns still cannot Adapt to the professional market that requires high pressure and large flow. [0003] Steven W. Post and William T. invented an electric grease gun (U.S.P6,315,327) consisting of a frame, a three-stage planetary gear reduction, a crank slider, a plunger, a switch, an oil supply system and a safety valve, but Its maximum output pressure is 6000pis, and its volume is large, and its operat...
