Manual hydraulic pump with adjustable supporting legs

Abstract

The invention provides a manual hydraulic pump with adjustable supporting legs, and relates to the technical field of hydraulic pumps. The manual hydraulic pump comprises a protective shell; a set of supporting blocks are arranged at the bottom of the protective shell, a hydraulic cylinder is fixed to the inner side of the protective shell through bolts, and a set of supporting mechanisms are symmetrically fixed to the outer side of the protective shell through bolts; a rotating shaft is mounted on one side of the hydraulic cylinder, and a hook is mounted on the rotating shaft; a connecting sleeve is arranged at one end of the hydraulic cylinder, and a handle A is mounted on the connecting sleeve. The hook is arranged on the hydraulic cylinder, after the handle A is fixed through the hook, the handle A can move downwards due to the influence of external factors, so that the hook and the handle A are staggered, and the phenomenon that the hook is not firmly fixed is caused; an arranged reset spring can push the hook to move downwards, the hook and the handle A are conveniently connected, and in the downward moving process of the handle A, the hook can synchronously move, so that the fixing effect of the hook is better.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pumps, and more specifically relates to a manual hydraulic pump with adjustable legs. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. The hydraulic pump is divided into automatic hydraulic pumps and manual hydraulic pumps. When a hydraulic pump is used in a narrow space, a manual hydraulic pump is used. When the existing manual hydraulic pump is used, it is pressurized by manually pressing the handle. [0003] For example, the Chinese invention patent with the application number: CN201510668623.0 discloses a manual hydraulic pump with a safety device in the field of mechanical technology, including a pump body, an operating handle, a switch handle, a switch rod, and a steel ball. It is charac...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a manual hydraulic pump with adjustable feet to solve the problem that the existing manual hydraulic pumps need to bend down to press or squat down to press the handle. The adjustable effect of the bottom of the pump is poor. When adding an adjustment mechanism, it needs to be added to the hydraulic pump. When the original structure of the hydraulic pump is changed, the hydraulic pump will be damaged to a certain extent, and a certain cost will be increased in production and maintenance. After the handle is stored, the handle will move downward due to any external factors, which will cause the displacement between the hook and the handle, and even make the hook break away from the fixation between the handle and the handle, causing the handle to bounce up.
