Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the overall structure of the present invention.
Fig. 2 is a top view of the overall structure of the present invention.
In the figure: the oil pump comprises a pump body 1, an adjusting handle 2, a manual reversing valve 3, a split pin 4, a left oil nozzle 5, a right oil nozzle 6, a fixed seat 7, an oil injection port 8 and a pressurizing rod sleeve 9.
Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1-2, a portable hand pump comprises a pump body 1, wherein a manual reversing valve 3 is mounted at the front part of the pump body 1, the upper end of the manual reversing valve 3 is connected with an adjusting handle 2, and the lower end of the manual reversing valve is limited by a cotter pin 4; the bottom of the pump body 1 is provided with a fixing seat 7, the top of the pump body 1 is provided with an oil filling port 8, and the side of the pump body 1 is provided with a pressurizing rod sleeve 9 used for pressurizing oil inside the pump body. Through adopting the pump is made to hand of above-mentioned structure, can carry out effectual pressurization to the inside fluid of pump body 1 under the rotation effect of pressurization pole sleeve 9, fluid after the pressurization enters into hand-operated directional control valve 3, passes in and out from corresponding glib talker through hand-operated directional control valve 3 control fluid, finally reaches the purpose of control fluid switching-over.
Furthermore, a left oil nozzle 5 and a right oil nozzle 6 are respectively arranged on two sides of the manual reversing valve 3; an adjusting handle 2 of a manual reversing valve is pulled to the side where the left oil nozzle 5 is located, oil is discharged from the left oil nozzle 5, and oil is returned from the right oil nozzle 6; a regulating handle 2 of the manual reversing valve is pulled to the right oil nozzle 6, oil is discharged from the right oil nozzle 6, and oil is returned from the left oil nozzle 5; when the adjusting handle 2 is positioned in the middle of the left oil nozzle 5 and the right oil nozzle 6, the manual reversing valve 3 is in a cut-off state, and the left oil nozzle 5 and the right oil nozzle 6 do not produce oil. The manual reversing valve 3 is convenient for controlling the oil circuit.
Furthermore, through holes are respectively processed on the fixing seats 7, and the through holes are matched with the fixing bolts and used for reliably fixing the pump body 1. Can be used for fixing whole pump body 1 through foretell fixing base 7, guaranteed in the follow-up use, can be convenient fixed.
Furthermore, a detachable oil hole plugging bolt is fixed at the top of the oil filling port 8. Through foretell oiling mouth 8 in the convenient to use oiling or evacuation pump body internal oil after finishing using. When oil is needed to be injected, the oil can be injected into the oil injection port 8 only by loosening the oil hole plugging bolt.
