Abstract

A hydraulic jack base convenient to repair comprises a one-way valve, oil return valves and a base body. The side wall of the base is provided with a plug mounting hole communicating with a channel A. The one-way valve is mounted in the plug mounting hole in a sealed mode to enable oil to only unidirectionally flow in the channel A from a buffer cavity oil discharge outlet to a working oil cavity oil inlet. Compared with the prior art, the hydraulic jack base has the following advantages that the one-way valve on the base is arranged on the side wall of the base and quite convenient to replace and wash, and an outer shell does not need to be dismounted and mounted; the side wall of the base is provided with the plug mounting hole communicating with the channel A, and the one-way valve is mounted in the plug mounting hole in a sealed mode; and the base is provided with the two oil return valves which are separately arranged on the two opposite side walls of the base, an operator can unscrew any oil return valve for unloading, and the condition that only one oil return valve exists, and accordingly operation is inconvenient under some circumstances due to the fact is avoided.

Description

technical field [0001] The invention relates to a hydraulic jack, in particular to a hydraulic jack base which is convenient for maintenance. Background technique [0002] Hydraulic jack is a common lifting device in industrial production. Figure 8 It is an existing structure of a hydraulic jack, including a base 4 , a housing 5 mounted on the base 4 , an oil cylinder 6 inside the housing 5 and a piston assembly 7 inside the oil cylinder 6 . An oil storage chamber 8 is provided between the base, the casing and the oil cylinder, and a working oil chamber 9 is provided between the base, the oil cylinder and the piston assembly, and the working oil chamber 9 and the oil storage chamber 8 are connected through an oil channel on the base , the oil passage includes an oil inlet passage for hydraulic oil to flow from the oil storage chamber to the working oil chamber and an oil return passage for hydraulic oil to flow back from the working oil chamber to the oil storage chamber. ...
