Abstract
The utility model relates to an oil pump, in particular to a closeable hand-cranked oil pump which comprises a pump cavity, a crank, an oil inlet, an oil outlet, an oil inlet pipe and an oil outlet pipe. The oil outlet is formed in the upper end of the pump cavity, the oil inlet is formed in the lower end of the oil cavity, and the crank is arranged at the side end of the oil cavity. The oil inlet and the oil inlet pipe are communicated with each other. The oil outlet and the oil outlet pipe are communicated with each other. The bottom end of the oil inlet pipe is fixedly connected with a sealing plug through a spring device. The sealing plug is a rubber plug. The side end of the sealing plug is fixedly connected with a pedal through an L-shaped rod. According to the oil pump, the inlet of the oil inlet pipe can be automatically closed after oil pumping work is finished, the service life of the oil pump is prolonged, and maintenance cost is saved.
Description
Technical field
The utility model relates to a kind of oil pump, especially can enclosed type Manual Oil Pumps Valves.
Background technique
Manual Oil Pumps Valves is widely used because it has feature easily easy to carry and use, but existing oil pump body is interior owing to there is no locking device, after oil pump finishes to pump operation, outside dirt or inner greasy dirt cannot be isolated, thereby can shorten the working life of body.
Model utility content
In order to overcome the easy contaminated deficiency of existing oil pump body, the utility model provides can enclosed type Manual Oil Pumps Valves.
The utility model solves the technological scheme that its technical problem adopts: can enclosed type Manual Oil Pumps Valves, comprise pump chamber, crank, filler opening, oil outlet, oil inlet pipe and oil outlet tube, pump chamber upper end is provided with oil outlet, lower end is provided with filler opening, side is provided with crank, filler opening is connected with oil inlet pipe, and oil outlet is connected with oil outlet tube, and the bottom of oil inlet pipe is fixedly connected with sealing plug by spring.
According to another embodiment of the present utility model, further comprise that closing cock is rubber stopper.
According to another embodiment of the present utility model, further comprise that closing cock side is fixedly connected with pedal by L-type bar.
The beneficial effects of the utility model are that this oil pump can, at the oil pumping end of job entrance of self-closed oil inlet pipe afterwards, extend the working life of oil pump, has saved maintenance cost.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
1. pump chambers in figure, 2. crank, 3. filler opening, 4. oil outlet, 5. oil inlet pipe, 6. oil outlet tube, 7. spring bar, 8. closing cock, 9. L-type bar, 10. pedal.
Embodiment
If Fig. 1 is structural representation of the present utility model, can enclosed type Manual Oil Pumps Valves, comprise pump chamber 1, crank 2, filler opening 3, oil outlet 4, oil inlet pipe 5 and oil outlet tube 6, pump chamber 1 upper end is provided with oil outlet 4, and lower end is provided with filler opening 3, side is provided with crank 2, filler opening 3 is connected with oil inlet pipe 5, and oil outlet 4 is connected with oil outlet tube 6, and the bottom of oil inlet pipe 5 is fixedly connected with sealing plug 8 by spring 7, closing cock 8 is rubber stopper, and closing cock 8 sides are fixedly connected with pedal 10 by L-type bar 9.
When staff shakes crank 2, when oil plant is up taken out oil plant from oil inlet pipe 5, tramp with one's feet and step on plate 10, pedal 10 will make closing cock 8 toward pressing down by L-type bar 9 like this, thereby closing cock 8 and the mouth of pipe of oil inlet pipe 5 are separated, can allow oil plant enter oil pump from the mouth of pipe, after the oil pumping end of job, only need to unclamp pedal 10, utilize the contraction performance of spring 7, just can make closing cock 8 again closed mutually with the mouth of pipe of oil inlet pipe 5, this oil pump can be at the oil pumping end of job entrance of self-closed oil inlet pipe afterwards, extend the working life of oil pump, save maintenance cost.
