Abstract
The utility model relates to an oil pump, in particular to a counterflow-preventing hand-operated oil pump. The oil pump comprises a pump cavity, a cranking bar, an oil inlet, an oil outlet, an oil inlet pipe and an oil outlet pipe, wherein the oil outlet is formed in the upper end of the pump cavity; the oil inlet is formed in the lower end of the pump cavity; the cranking bar is arranged at the side end of the pump cavity; the oil inlet is communicated with the oil inlet pipe; the oil outlet is communicated with the oil outlet pipe; the inner wall of the oil inlet pipe is hinged with the tail end of an oil baffle plate; and a baffle block is arranged on the inner wall of the oil inlet pipe on the lower side of the top end of the oil baffle block. When the oil baffle plate is perpendicular to the oil inlet pipe, the top end of the oil baffle plate is attached with the inner wall of the oil inlet pipe, and the oil baffle plate adopts a ceramic plate. The oil pump can prevent residual oil in the pipe from flowing out, so that the pollution of the working environment is avoided, and the maintenance cost is saved.
Description
Technical field
The utility model relates to a kind of oil pump, especially anti-reverse flow pattern 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 the device of counterflow-preventing, when oil pump finishes the operation of pumping, thereby when oil inlet pipe is extracted, in pipe, residual oil plant can flow out in oil inlet pipe, thereby has polluted working environment.
Model utility content
Have in order to overcome existing oil pump the deficiency that Residual oil is revealed, the utility model provides anti-reverse flow pattern Manual Oil Pumps Valves.
The utility model solves the technological scheme that its technical problem adopts: anti-reverse flow pattern 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, and filler opening is connected with oil inlet pipe, and oil outlet is connected with oil outlet tube, the inwall of oil inlet pipe and oil baffle plate tail end are hinged, and the oil inlet pipe inwall of the top downside of oil baffle is provided with link stopper.
According to another embodiment of the present utility model, further comprise when oil baffle plate and oil inlet pipe are mutually perpendicular, its top and oil inlet pipe inwall fit.
According to another embodiment of the present utility model, further comprise that oil baffle plate is ceramic plate.
The beneficial effects of the utility model are that this oil pump can prevent that the oil plant of managing interior remnants from flowing out, thereby has avoided the pollution of working environment, 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. oil baffle bar, 8. link stopper.
Embodiment
If Fig. 1 is structural representation of the present utility model, anti-reverse flow pattern 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, lower end is provided with filler opening 3, side is provided with crank 2, filler opening 3 is connected with oil inlet pipe 5, oil outlet 4 is connected with oil outlet tube 6, the inwall of oil inlet pipe 5 and oil baffle plate 7 tail ends are hinged, and oil inlet pipe 5 inwalls of the top downside of oil baffle 7 are provided with link stopper 8, when oil baffle plate 7 is mutually perpendicular with oil inlet pipe 5, its top and oil inlet pipe 5 inwalls fit, oil baffle plate 7 is ceramic plate.
When staff shakes crank 2, when oil plant is up taken out oil plant from oil inlet pipe 5, oil plant can be washed oil baffle plate 7 open, and oil baffle plate 7 is now less than 90 degree with the inwall distance of oil inlet pipe 5, and oil plant extracts and do not have obstruction.In the time that oil plant extracts end, the pressure that impacts oil baffle plate 7 can disappear, now oil baffle plate 7 can be because thereby gravity falls back on block 8, thereby form the sealing of 5 mouthfuls of oil inlet pipes, and remaining oil plant in oil inlet pipe 5 can be kept off in pipe by oil baffle 7, thus the adverse current of preventing, and this oil pump can prevent that the oil plant of managing interior remnants from flowing out, thereby avoid the pollution of working environment, saved maintenance cost.
