Direct-current electric grease gun

Abstract

A direct-current electric grease gun belongs to the technical field of lubricating devices using grease, and comprises an outer packaging casing, a body, a one-way valve, a rotation and reciprocation switching mechanism, a planetary reduction mechanism, a grease storage cylinder, a driving mechanism, an operating mechanism, a vent valve, a grease charging valve, a grease discharge valve and a display screen. The body comprises a plate top, a slide rod hole seat, a grease outlet and a grease inlet. The slide rod hole seat is provided with a slide rod hole. The rotation and reciprocation switching mechanism comprises a rotary disk, an eccentric post, an eccentric post sleeve, a slider and a slide rod. The slider comprises a rear slide slot and a front connecting part, and the eccentric post sleeve and the eccentric post are disposed in the slide slot. The slide slot is in an arc shape with the front end curved and has a radian of 0.14 pi to 0.16 pi. The slider is disposed on the rotary disk. The eccentric post and the eccentric post sleeve are disposed in the arc slide slot of the slider and are connected in a floating manner. The slide rod is in clearance fit with the slide rod hole. The direct-current electric grease gun has the advantages that the direct-current electric grease gun has simple structure, the slider is low in resistance to motion, stable to move and less prone to being blocked.

Description

technical field [0001] The invention relates to an electric grease gun, in particular to a DC electric grease gun, which belongs to the technical field of lubricating devices using butter. Background technique [0002] The invention is a tool for conveniently and rapidly filling butter to automobiles, tractors and various engineering machinery. The earliest used grease gun is composed of grease nozzle, plunger cylinder, oil storage cylinder and pressure handle, etc. It has a simple structure and low price. However, due to manual operation, there are problems such as slow oil injection speed, low oil output, high labor intensity, and pressure cannot be increased. The defect is that it is difficult to operate in the occasions that require high pressure. [0003] The structure of the electric grease gun that appeared later was more complicated, and the movement of the slider had to cooperate with the chute on the body. For example, the patent number is 200420081347.5, and the...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to aim at the above-mentioned prior art, the structure of the electric grease gun is relatively complicated, and the movement of the slider must cooperate with the chute on the machine body. For the defect of oil, a novel DC electric grease gun is provided, which can achieve the purpose of not being easily stuck when the slider moves back and forth, the movement resistance of the slider is small, the operation is stable, no oil leakage, and the work efficiency is high.
