Oil supply structure of hydraulic electric jack

Abstract

The invention provides an oil supply structure of a hydraulic electric jack, belonging to the technical field of jacks and solving the technical problems of easy oil leakage, easy pollution, short service life and the like existing in the oil supply structure of the traditional hydraulic electric jack. In the oil supply structure of the hydraulic electric jack, the hydraulic electric jack comprises a base and a lifting structure. The oil supply structure comprises an oil tank, an oil inlet channel and an oil outlet channel, wherein the oil tank is arranged on the base of the electric jack, one ends of the oil inlet channel and the oil outlet channel are communicated with the oil tank and the other ends are connected with the lifting structure of the hydraulic electric jack. The oil supply structure is characterized in that the oil tank is in a bag shape and is made of elastic materials. The invention has the advantages of more stable oil supply, difficult leakage of hydraulic oil, longer service life, and the like.

Description

technical field [0001] The invention belongs to the technical field of jacks, and relates to a hydraulic electric jack, in particular to an oil supply structure of the hydraulic electric jack. Background technique [0002] The jack can lift the heavy object to facilitate the maintenance of the heavy object. There are mechanical jacks and hydraulic jacks. Mechanical jacks have poor working stability, high working noise and short service life. The hydraulic electric jack has advantages that the mechanical jack does not have. The hydraulic electric jack needs to be equipped with an oil supply structure. The oil supply structure is used to supply hydraulic oil or receive hydraulic oil for the jacking structure when the jack is working. The oil supply structure of the hydraulic electric jack mainly includes a fuel tank, an oil inlet channel and an oil outlet channel. The oil tank is connected to the oil inlet channel and the oil outlet channel, and the oil inlet and outlet chann...

AI Technical Summary

Problems solved by technology

However, the jack needs to be moved frequently during normal use, especially the hydraulic electric jack for vehicles, which needs to be placed in the vehicle frequently, and the vehicle sometimes drives on bumpy roads, which will cause the hydraulic oil to overflow the outside of the fuel tank and make the jack The surface cleanliness is poor, and hydraulic oil needs to be added frequently, and because the inside of the oil tank is connected to the outside world, dust from the outside will enter the oil tank, and the hydraulic oil will be dirty, which will accelerate the damage of the oil pump and jacking structure, making the hydraulic electric jack service life cannot be guaranteed
