Abstract

The utility model relates to a manual reciprocating type oil suction and injection device, belonging to the class of tools. The manual reciprocating type oil suction and injection device solves the problems that the volume of an oil pumping device is large, the oil pumping device is inconvenient to be carried, the oil pumping device only can suck oil, and can not inject the oil, the oil pumping device pollutes oil quality, etc. The manual reciprocating type oil suction and injection device is composed of a bushing, a piston, a front end cover, a rear end cover, an oil inlet, an oil outlet, and a handle. The piston is pulled out from the interior of the bushing, and vacuum and negative pressure are formed. After a steel ball on a front end is jacked up by oil, the oil enters the interior of the bushing. The piston is pushed out, after the steel ball on the piston is jacked up by the pressure generated by the oil inside the bushing, the oil enters the rear segment of the bushing. When the piston is pulled out again, an oil hole is blocked to death by the steel ball on the piston, and the oil of the rear segment of the bushing is pushed towards the oil outlet. Due to the fact that the oil is pressed to enhance, and the purpose that one machine has multiple functions that the manual reciprocating type oil suction and injection device not only can suck the oil, but also can inject the oil is realized.

Description

Manual reciprocating oil suction and injection device

The utility model relates to a kind of oil pumping oil filler, and specific description is that a kind of pair non-return valves that utilize are taken out the oil filler of taking out of oiling.

Existing oil-sucker inhales not only that journey is little, efficient is low but also oil pollution is worked the mischief, and the big heaviness of body is not portable, can only pump and can not refuel.

The purpose of this utility model is to provide a kind of oil pumping oil filler that overcomes the above-mentioned shortcoming of existing oil-sucker, has particularly solved the difficulty that automobile axle refuels.

In the utility model, have an oil inlet pipe 12 oil inlet pipe tail ends on the front cover 15 of urceolus 5 and have a ball valve, this ball valve only allows oil to enter urceolus 5, and does not allow oil to discharge from oil inlet pipe 12.The rear portion of urceolus 5 has on the rear end cover 3 of oil outlet tube 16 urceolus tail ends, have seal ring 2 and perforate, insert push rod 14 in this hole, the rear end of push rod 14 has handle and does not have with urceolus 5 interior along the sealing cup 7 that slides, the one-way valve that steel ball 13 in the valve seat at piston center and the valve seat constitutes, make oil can only enter urceolus 5 inner carrier rear ends, and can not pass back into the space between piston and the front cover 15.

At first handle 1 is outwards pulled out in use, push rod 14 drives piston and moves at end cap 3 places backward, steel ball 13 on the piston seals the perforate on the valve seat at this moment, make and form vacuum in the piston space between urceolus and inner carrier and the front cover 15, and the generation negative pressure, the ball valve of oil inlet pipe 12 place's steel balls 11 is opened, oil is inhaled in this space, be pulled to the position of outermost when handle 1, be full of 3 oil in the above-mentioned space, then handle 1 is advanced in urceolus 5, this moment, the ball valve oil at front cover 15 places produced pressure, thereby this moment, pressure was pushed steel ball to the oil inlet hole sealing, again the ball valve on the piston is opened, oil enters piston closes through piston, and extruded oil this moment once more by the pipe between oil inlet pipe 12 suction pistons and the front cover 16, when handle 1, when repeating above-mentioned push-and-pull campaign, oil is constantly sucked by oil inlet pipe 12, and be forced out, realized the purpose of pump drainage oil for this reason by oil outlet tube 16.

Advantage of the present utility model and positive effect.

The utility model not only is used for oil pumping and refuels, and can be used for various liquid.Its advantage is:

1, this to take out the oil filler volume little easy to carry.

2, this takes out oil filler because volume is convenient to keeping, has stopped to be stained with the phenomenon of contamination by dust oil.

3, originally take out oil filler and inhale lift and respectively reach 6 meters, so the depths can drink up, eminence can force up, and level is refueled beat farther.

4, originally taking out oil filler can take out and can add the function that reaches a tractor serves several purposes.

5, this oil filler is simple in structure, sturdy and durable, cost is low.

6, originally take out oil filler and can clean vehicle.

Accompanying drawing is a structural representation of the present utility model.

Claims

This is the reciprocating type oil filler of taking out manually, it is characterized in that this takes out oil filler and have urceolus, urceolus has front cover and rear end cover, on the front cover by having oil inlet pipe and one oil inlet pipe can be opened and sealed ball valve, the urceolus rear portion has an oil outlet tube, push rod is in rear end cover stretches into urceolus, and its front end is by adorning a piston that is made of valve seat and steel ball valve gap, and putting back-end has handle.
