Portable jack for automobile maintenance

Abstract

The invention discloses a portable jack for automobile maintenance, and relates to the technical field of jacks for automobiles. The portable jack comprises a bottom plate, wherein an oil tank is welded to the upper end of the bottom plate, a large cylinder is welded to one side of the upper end of the oil tank, a large piston is mounted in the large cylinder, a panel is mounted at the upper end of the large piston, pressure sensors are mounted on the peripheral side below the panel, a small cylinder is welded to the other side of the upper end of the oil tank, a small piston is mounted in thesmall cylinder, a hinge is installed at the upper end of the small piston, and sleeves are installed on the peripheral side of the hinge. By arranging a control display screen, the pressure sensors and a moving device, the current pressure borne by the jack can be known conveniently, the jack can be moved conveniently, use is convenient; and by arranging a telescopic device, the strength of a user can be reduced, the length of the telescopic device can be adjusted according to the comfort degree of the user, and force can be applied easily during use.

Description

technical field [0001] The invention belongs to the technical field of jacks for automobiles, in particular to a portable jack for automobile maintenance. Background technique [0002] Jack is a kind of light and small lifting equipment that uses a rigid top lifting part as a working device, and lifts a weight in a stroke by a top bracket or a bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. Its structure is light and strong, flexible and reliable, and can be carried and operated by one person. However, most of the portable jacks for car maintenance on the market cannot intuitively understand the pressure on the jack when using the jack. The distance between the lever device is fixed and it is not easy to hold it by hand. The power is not comfortable enough, and there is no handle device when moving, so the movement is not convenient enough. Contents of the invention...
