Abstract
The utility model relates to an improved manual high-pressure grease pump, which comprises a bucket body and a bucket cover installed at the upper end of the bucket body, wherein an oil-pressing tray is installed in the bucket body, a pressure increasing mechanism and a pump body are installed on the bucket cover, the pump body is installed at the axis center of the bucket cover, an oil guide pipe is arranged inside the bucket cover corresponding to the pump body, and the oil guide pipe penetrates through the oil-pressing tray. The grease pump further comprises a press rod, the upper end of the press rod is hinged with a handle of the pressure increasing mechanism, the bottom of the press rod penetrates through the pump body to be installed inside the oil guide pipe and connected with a piston rod, and a piston is connected with the bottom of the piston rod. The grease pump is characterized in that a guide sleeve is sleeved on the periphery of the oil guide pipe, and the guide sleeve is connected with the oil-pressing tray through a bolt. The grease pump has the advantage that the oil-pressing tray is fixed on the oil guide pipe through the guide sleeve, does not incline during the ascending and descending of the press rod, thereby avoiding evacuation and explosion of pipes.
Description
Technical field
The utility model relates to a kind of high pressure manual greasing pump, is used for to the lubricated position filling grease of needs.
Background technique
Pressure food tray in the existing greasing pump is to be installed in the staving by rubber pad, and in the process that depression bar rises or descends, along with the minimizing of grease, it is insecure to press food tray to descend, and is easy to generate inclination, produces vaccuum phenomenon, and then booster takes place.
Summary of the invention
The purpose of this utility model provides a kind of improved high pressure manual greasing pump, insecure with the pressure food tray that the solution prior art exists, as to be easy to generate and to find time, take place booster problem.The technical solution of the utility model is: a kind of improved high pressure manual greasing pump, comprise staving and the bung that is installed in the staving upper end, the pressure food tray is installed in the described staving, the pressure-raising mechanism and the pump housing are installed on the described bung, the described pump housing is installed in the place, axle center of bung, inside and pump housing corresponding section at bung are provided with oil guide pipe, described oil guide pipe passes the pressure food tray, also comprise a depression bar, the handle of the upper end of described depression bar and pressure-raising mechanism is hinged, the inside that the pump housing is installed in oil guide pipe is passed in its bottom, and be connected with piston rod, bottom at piston rod is connected with piston, it is characterized in that: be with a guide sleeve in the periphery of described oil guide pipe, this guide sleeve is connected by bolt with pressing food tray.
The bottom of the described oil guide pipe steel bushing that is threaded, described piston rod is installed in the steel bushing, described piston and steel bushing cross hydraulic fluid port movingly.
Described pressure-raising mechanism also comprises support, and the two ends of described support are hinged respectively at the pump housing and handle.
On the bung of described connecting rod opposite side gland is installed, described gland is installed in the positive bottom of handle.
Between described piston rod and the oil guide pipe seal ring is installed.
The utility model has the advantages that: press food tray to be fixed on the oil guide pipe, in the process that depression bar rises or descends, can not produce inclination, thereby prevent vaccuum phenomenon, finally prevented the generation of booster phenomenon by guide sleeve.
