Abstract

The utility model discloses a lever manual piston oil barrel pump, which comprises a bottom valve, a pump body, a piston, a pump spindle, a female screw, a pump seat, a cantilever, a pendulum bar, a handle and a pin. The bottom valve is arranged on a lower end port of the pump body, the upper end is connected with a pump seat, the pump spindle is longitudinally positioned through the pump seat, and an oil outlet and the cantilever are respectively arranged on two sides of the pump seat. The piston is arranged in an inner cavity of the pump body and is connected with the pump spindle. The handle in the utility model is hinged with the pendulum bar, the pump spindle and the cantilever through the pin to form a four connecting bar mechanism, when oil is pumped, a hand holds the handle to raise upwards and press downwards, the pump spindle drags the piston to move upwards and downwards in the inner cavity of the pump body, and alternative movement of a bottom valve core and a valve core is formed to finish the process for oil suction and oil output. The barrel pump of the utility model transmits manpower through a lever handle to realize the oil suction and oil output, the structure is simple, the operation saves labor, the efficiency is high, which is in particular suitable for being used as a tool for sucking oil manually under the condition that power supply is not available.

Description

The manual piston oil barrel pump of lever

Technical field

The utility model relates to a kind of pump, particularly a kind of hand pump that is used to aspirate the oil drum inner fluid.

Background technique

The standard oil drum is a kind of common store oil seal container, and it is very inconvenient to extract fluid from oil drum under the non-transformer occasion.Prior art has the device of two kinds of manpower suction oil, and a kind of is to do the siphon mode oil suction with flexible pipe, and this kind Oil sucking device is simple, effective, but fluid unhygienic, output does not have pressure, oil transportation apart from weak point, removes the special circumstances people and does not generally use this mode oil suction.The oily device of another kind of suction is common Manual Oil Pumps Valves, and the type pump utilizes the relative alternating motion with slide plate of eccentric wheel in the hand rotation pump housing and produces volume-variation and alternately oil suction or output are oily, and Manual Oil Pumps Valves is simple in structure, cheap, easy to carry.But Manual Oil Pumps Valves handle running torque is little, and parts such as the pump housing are in oil drum top in addition, and it is difficult to form negative pressure oil suction condition, and oil suction efficient is low, and the oil transportation distance is limited, and its performance can not satisfy people's actual demand.

The model utility content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, rapid operation, oil suction efficient height are provided, and the fluid of output has the manual piston oil barrel pump of lever of certain pressure.

The utility model is achieved through the following technical solutions technical goal.

The manual piston oil barrel pump of lever, it comprises bottom valve, the pump housing, piston, pump shaft, nut, pump seat, cantilever, fork, handle and pin.The described pump housing is a kind of pipe shape member, and the pump housing lower end mouth of vertically-arranged is provided with bottom valve, and the bottom valve outer wall is provided with radial direction through hole, and the axial bore upper end is provided with the bottom valve core that floats and cooperate.The pump seat radial location pump shaft that pump housing upper end connects.Described piston places and is Spielpassung in the pump housing, and piston head is connected with pump shaft, and the uniform radial direction through hole of stage casing outer wall, spool place piston axial bore upper-end surface to be and float and cooperate.Its improvements are: described pump seat one side is provided with oil outlet, and opposite side is provided with cantilever.Described handle is hinged fork, pump shaft and cantilever by pin and constitutes four connecting rod reciprocating mechanisms.

Pump shaft, cantilever, handle, fork constitute four connecting rod reciprocating mechanisms in the said structure.The fork two ends are hinged the cantilever right-hand member by pin respectively and the handle stage casing constitutes the strong point that handle is swung, press down handle and then promote pump shaft and affect and shift in the pump oil suction on the piston simultaneously from pump seat oil outlet output oil, last handle then pump shaft promotion piston moves down trapped fuel in the pump of piston bottom is moved to piston top.

The utility model compared with prior art has following good effect:

1, piston moves up and down by parallel motion and realizes that it is simple in structure, easy to manufacture;

2, it is laborsaving to put press operation on the Lever type handle, oil transportation efficient height;

3, move compression fluid on the piston and carry pressure output, oil transportation distance from oil outlet.

Description of drawings

Accompanying drawing is the utility model structural representation.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

The manual piston oil barrel pump of lever shown in the drawings, it comprises bottom valve 1, the pump housing 2, piston 3, pump shaft 4, nut 5, pump seat 6, cantilever 7, fork 8, handle 9 and sells 10.The described pump housing 2 is a kind of tubular members, and the pump housing 2 lower end mouth of vertically-arranged are provided with bottom valve 1, the uniform radial direction through hole 1.1 of bottom valve 1 outer wall, in establish axial hole upper end and float to cooperate and constitute one-way valve structures.The pump housing 2 upper ends connect pump seat 6 also is fixed in oil drum with nut 5 nozzle, and pump shaft 4 cooperates with pump seat 6 upper end through holes, and pump seat 6 left sides are provided with oil outlet 6.1, and the right side is provided with cantilever 7.Piston 3 places the pump housing 2 inner chambers to be moved up and down along inwall by pump shaft 4 tractions.Piston 3 axial stage casing outer walls are provided with radial direction through hole 3.1, and piston 3 axial bore upper end is provided with the spool 3.2 that cooperates that floats and constitutes one-way valve structures.Handle 9 in the utility model, fork 8, cantilever 7, pump shaft 4 constitute four connecting rod reciprocating mechanisms by pin 10.Suction is held handle 9 during fluid and is made to put the moving pump shaft 4 traction pistons 3 of pressure zone and move up and down in the pump housing 2.Forming local negative pressure when piston 3 is up makes bottom valve core 1.2 be held up by fluid, fluid flows into the pump housing 2 from radial hole 1.2, spool 3.2 in the piston 3 is in the situation of closing under gravity and condition of negative pressure at this moment, and piston 3 tops institute trapped fuel liquid is from 6.1 outputs of pump seat 6 oil outlets.When piston 3 was descending, the fluid of 3 pairs of suction pump housings 2 of piston was exerted pressure, and closed the filler opening of bottom valve 1 automatically at malleation and the gravity condition spool 1.2 of going to the bottom, and piston 3 compression fluid form malleations and back down spool 3.2, and fluid flows to pump seat 6 from radial direction through hole 3.1.The utility model transmits manpower by the Lever type handle and realizes suction oil, and simple in structure, rapid operation, efficient height are a kind of desirable allows manual aspiration oil devices.
