Problems solved by technology

[0003] However, the existing jack oil pumps are either pneumatic oil pumps or manual oil pumps, which cannot be used for both pneumatic and manual purposes, and are inconvenient to use. Moreover, the existing air jack oil pumps and manual jack oil pumps still have the problem of inconvenient manipulation.

Abstract

The invention discloses a pneumatic manual dual-purpose oil pump and a jack. The pneumatic manual dual-purpose oil pump comprises a shell body, an oil tank and a pneumatic booster pump arranged in theshell body, an oil-way control plate arranged at the front end of the shell body and a hand driving mechanism, a pneumatic high-pressure oil outlet and a manual high-pressure oil outlet at the frontend of the oil-way control plate are connected with a three-way connector, a pneumatic oil supply channel in the oil-way control plate is sequentially connected with a first one-way valve, the pneumatic booster pump and a second one-way valve, a pneumatic oil return channel in the oil-way control plate is connected with a pneumatic pressure release valve, a manual oil supply channel in the oil-waycontrol plate is connected with a third one-way valve, a plunger cavity and a fourth one-way valve, a plunger rod is matched in the plunger cavity, the hand driving mechanism drives the plunger rod for piston motion, and a manual pressure release valve is arranged on the manual oil return channel in the oil-way control plate. The oil pump and the jack can be driven by hand and can also be drivenby the pneumatic booster pump, so that the oil pump and the jack are flexible to use and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a pneumatic and manual dual-purpose oil pump and a jack. Background technique [0002] Jack is a kind of hydraulic lifting equipment, commonly used in fields such as automobile maintenance. The jack is mainly driven by the jack oil pump. The existing jack oil pump mainly has two types: pneumatic and manual. The pneumatic jack oil pump is mainly driven by the pneumatic booster pump to press the hydraulic oil into the jack oil cylinder. The piston movement of the stopper rod presses hydraulic oil into the cylinder of the jack. [0003] However, the existing jack oil pumps are either pneumatic oil pumps or manual oil pumps, which cannot be used for both pneumatic and manual purposes, and are inconvenient to use. Moreover, the existing air jack oil pumps and manual jack oil pumps also have the problem of inconvenient manipulation. Contents of the invention [0004] Ai...
