Abstract

The invention discloses a disconnect-type oil jack which comprises an oil storage cylinder and a pump body installed at the front end of the oil storage cylinder. An operation handle is arranged on the pump body, a hydraulic cylinder is connected to the pump body; a piston rod of the hydraulic cylinder is controlled to go up and down through the operation handle; a rear seat is arranged at the rear end of the oil storage cylinder; an oil charge valve is fixedly arranged on the top of the rear seat; an oil charge opening is formed in the top of the rear seat; the oil charge valve comprises a first O-type sealing ring and a bolt; the first O-type sealing ring is clamped by screwing of the bolt through the oil charge valve so as to seal the oil charge opening; an observing opening enabling a user to observe the amount of oil storage is formed in the upper end of the rear seat, and is provided with a transparent safety board; the safety board is connected with the rear seat in a sealing mode. Due to the adoption of the technical scheme of the disconnect-type oil jack, the oil charge valve is arranged on the top of the rear seat, the position of the oil charge valve is reasonable, and the oil charge valve is simple in structure; because only the bolt and the first O-type sealing ring are used for fastening and sealing, the oil charge opening is good in sealing performance, stable to work, and convenient to open or close.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a separate hydraulic jack. Background technique [0002] Ordinary jacks, the power source and actuators are integrated, and cannot meet specific practical requirements under special working environment conditions; while ordinary separate jacks, the refueling valve is set on the left side of the rear seat, and the refueling port is also set On the left side, the refueling operation and sealing are troublesome, and oil leakage often occurs due to poor sealing, and special tools are needed to assist in opening and closing the refueling port, and the work efficiency is low. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a separated hydraulic jack with reasonable structural design, convenient operation, good sealing performance of the oil filling port and stable operation. [0004] In order to achieve...
