Abstract

The invention discloses a manual hydraulic grease gun, which is characterized in that the upper end of the handle of a grease gun is provided with a main lateral grease tank; communicating assistant grease tanks are arranged above the main grease tank; the front end of the main grease tank is provided with a grease cylinder of which the front end is provided with a grease nozzle; a grease discharge plug is arranged in the grease cylinder and is provided with a draw bar which passes through a coupling nut and the main grease tank; the rear end is provided with a draw bar handle; the lower part of the handle of the grease gun is provided with a grease pressing compartment provided with a grease suction valve therein; the middle of the handle of the grease gun is provided with a lateral grease pressing cavity provided with a grease pressing piston therein; the grease pressing cavity is communicated with a grease cylinder by the grease pressing valve and a high-pressure grease pipe; the front side of the grease pressing cavity is provided with a trigger; and a piston shaft is arranged between the trigger and the grease pressing piston. The manual hydraulic grease gun solves the problem of complex operation for smearing grease, and can be widely applied to various occasions of mechanical production, maintenance and the like.

Description

technical field [0001] The invention relates to the field of lubricating and anti-rust equipment for mechanical equipment, in particular to a special tool for adding butter for mechanical anti-friction. Background technique [0002] At present, in the process of adding butter to machines, people do it manually. The disadvantage is that the operation is cumbersome, especially for some small gaps, it is difficult to add oil in place. Contents of the invention [0003] In order to solve the problem of complicated operations for adding butter to machines, the present invention invents a pistol-shaped hydraulic injection type butter adding device. [0004] The technical solution of the present invention is a manual hydraulic grease gun, which is special in that a horizontal main oil tank is installed on the upper end of the handle of the oil gun, and a connected auxiliary oil tank is installed above the main oil tank, and an air inlet valve is installed on the upper wall of the...
