Embodiment
With reference to specific embodiment, the invention will be further described, the illustrative examples and explanation invented herein
For explaining the present invention, but it is not as a limitation of the invention.
As shown in Figure 1, Figure 2, Figure 3 shows, the adaptive hand grease gun of a kind of double mode, including oil storage barrel 1, the and of pitch brace 2
Draw-bar seat 9, hand rest 3 and handle 4, hand piston 5, connecting rod 6, the pump housing 8 and nozzle 7, oil storage barrel piston 11 and spring 12.Oil storage barrel
1 is arranged on the side of the pump housing 8；The described coaxially slide of pitch brace 2 is arranged in oil storage barrel 1, and the one end of pitch brace 2 is co-axially mounted
There is draw-bar seat 9, the other end of pitch brace 2 is provided with baffle ring, hand rest 3 is provided with the outside of baffle ring.Oil storage barrel piston 11 is co-axially mounted
On pitch brace 2, and it is located at the rear portion of draw-bar seat 9.Spring 12 is arranged on pitch brace 2, and the one end of spring 12 compresses oil storage barrel
Piston 11, the other end of spring 12 are pressed on the baffle ring of pitch brace.Hand piston 5 is arranged on the top of the pump housing 8, and with the pump housing 8
Portion communicates.The one end of connecting rod 6 is hingedly mounted on the side of the pump housing 8, and the other end of connecting rod 6 is be hinged to be provided with handle 4, the middle part of handle 4 and hand
The top of piston 5 is hinged installation.Nozzle 7 is arranged on the side of the pump housing 8, and with being communicated inside the pump housing 8.Oil storage barrel piston 11 with
O-ring seals 10 are installed on the excircle that oil storage barrel 1 contacts.
The hydraulic system of pump body is as described below：Form two chambers between hand piston 5 and the pump housing 8, be respectively on
The small chamber of the big chamber in portion and bottom.The big chamber in top is connected by pipeline with oil storage barrel 1, installation inlet one-way valve 1 among pipeline, oil
Road direction is from oil storage barrel 1 to the big chamber in top；The small chamber in described bottom is connected by pipeline with oil storage barrel 1, install among pipeline into
Mouth check valve 2 14, oil circuit direction is from oil storage barrel 1 to the small chamber in bottom；The big chamber in described top is connected by pipeline with nozzle 7, pipe
Installation outlet check valve 1 among road, oil circuit direction is from the big chamber in top to nozzle 7.The small chamber in bottom passes through pipeline and the phase of nozzle 7
Even, installation outlet check valve 2 17 among pipeline, oil circuit direction is from the small chamber in bottom to nozzle 7.Nozzle 7 passes through pipe with oil storage barrel 1
Road is connected, and installation high-pressure overflow valve 16 among pipeline, after reaching setting pressure, is connected at nozzle 7 with oil storage barrel 1.It is living manually
Hydraulicdirectional control valve 15 is provided between the big chamber in top and oil storage barrel 1 of plug 5, after setting pressure is reached, hydraulicdirectional control valve 15 will
The big chamber in top of hand piston 5 is connected with oil storage barrel 1.Between the big chamber in top and Outlet check valves 1 of hand piston 5
Low pressure relief valve 19 is provided with pipeline, after reaching setting pressure, the big chamber in top of hand piston 5 is connected with oil storage barrel 1.
The present invention operation principle be：Before using grease gun, first oil storage barrel 1 is backed out from the pump housing 8, then pulled back
Support of starting 3, oil storage barrel 1 is attached on the pump housing 8 again after being put into butter from front end, hand rest 3 is finally back into bottom；Work of the present invention
Work can be divided into the quick oil-filled and oil-filled both of which of small flow high pressure of low pressure and mass flow, and can be automatically performed conversion；Work as job family
When system needs low pressure quickly oil-filled, carrying handle 4 upwards rises hand piston 5, the big chamber of the small chamber in the bottom of hand piston 5 and top
There is vacuum, vacuum caused by pressure and hand piston 5 that now butter is applied by spring 12 by oil storage barrel piston 11 is dual
Under effect, the small chamber in the bottom of hand piston 5 and upper is respectively enterd by 2 14 points of two-way of inlet one-way valve 1 and inlet one-way valve
The big chamber in portion completes oil-absorbing process；Handle 4 is pressed, because the unidirectional logical oil of inlet one-way valve 1 and inlet one-way valve 2 14 is special
Property, butter will not former road return in oil storage barrel 1, during due to low pressure, low pressure relief valve 19 will not be opened, and pilot operated directional control valve 15 exists
Closed under spring effect, butter is entered at nozzle 7 by Outlet check valves 2 17 and Outlet check valves 1, at nozzle 7
Pressure, i.e., system pressure be not up to high-pressure overflow valve 16 setting pressure before, high-pressure overflow valve 16 is closed, now
Butter is returned in oil storage barrel 1 without going past high-pressure overflow valve 16；During buying oil, system pressure is increased to pilot operated directional control valve 15
Operating pressure after, pilot operated directional control valve 15 is acted, and the big chamber in the top of hand piston 5 is connected with oil storage barrel 1, now, press handle 4
When the top of hand piston 5 big chamber will no longer to system fuel feeding, the small chamber in the bottom of hand piston 5 still through Outlet check valves 2 17 to
System fuel feeding, so as to complete conversion of the low pressure and mass flow to high-pressure low-flow.
The effect of mesohigh overflow valve 16 of the present invention：Set up grease gun highest to buy oil pressure, protection grease gun will not be because super
Press and damage.Mesolow overflow valve 19 of the present invention acts on：The maximum pressure of the big chamber in top of grease gun hand piston 5 is set, is prevented
Pilot operated directional control valve 15 completely commutation or it is stuck when hand piston bottom big cavity pressure rise too high cause can not armrest pressure buy oil
Situation occur.
