Efficient hydraulic jack

Abstract

The invention provides an efficient hydraulic jack, and relates to the field of mechanical auxiliary devices, specifically to the efficient hydraulic jack which comprises a large cylinder plunger anda pump cylinder, wherein the large cylinder plunger is arranged in a large cylinder barrel; the lower part of the large cylinder barrel is connected with a fuel tank through a stop valve; a small cylinder plunger is arranged in the large cylinder plunger; the inner cavity of the large cylinder plunger is connected with the fuel tank through a first one-way valve, and is connected with the pump cylinder through an oil pressing one-way valve; a piston is arranged in the pump cylinder, and is connected with a pressure lever; and the pump cylinder is connected with the fuel tank through an oil absorption one-way valve. The efficient hydraulic jack can be moved fast in a no-load stage, so that time is saved, the work efficiency is increased, the bearing capacity is high, and the operation is safe and reliable.

Description

technical field [0001] The invention relates to the field of mechanical auxiliary devices, in particular to a high-efficiency hydraulic jack. Background technique [0002] At present, there are two types of lifting tools carried on the vehicle, screw jacks and hydraulic jacks, all of which are manually operated, which is time-consuming, labor-intensive, poor working conditions and low safety. As cars and other small and medium-sized cars gradually enter the family, traditional manual jacks are becoming less and less popular, and in the no-load stage, the pressure head cannot move quickly, resulting in low work efficiency and high labor intensity. Contents of the invention [0003] In order to solve the above problems, the present invention provides a safe and reliable high-efficiency hydraulic jack that can move quickly in the no-load stage, saves time, improves work efficiency, and has a large bearing capacity. [0004] The high-efficiency hydraulic jack of the present i...
