Embodiment

The embodiment represented by 1-3 is further described to the utility model below in conjunction with the accompanying drawings：

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of note plug grease pump, including grease chamber 1, power section 2 and oil-feed part 3, oil Room 1 is provided with the oil outlet 4 being in communication with the outside, and power section 2 is arranged on plane on grease chamber 1, and oil-feed part 3 passes through under grease chamber 1 One connecting hole 5 of plane is arranged on the lower plane of grease chamber 1, and the oil-feed part 3 includes being done up and down reciprocatingly by what power section 2 was controlled The note plug pipe 7 of motion, the outside of note plug pipe 7 is cased with outer tube sleeve 6, and the lower end of outer tube sleeve 6 is bolted with into oil jacket 8, and note plug pipe 7 upper end is passed through The through hole of plane one is connected with power section 2 on grease chamber 1, and note plug pipe 7 is the hollow tubular structure that bottom open top is closed, note plug The inside of pipe 7 is provided with check valve A10 and check valve B18 of the liquid towards the lower end outflow of note plug pipe 7 is prevented, check valve B18 is located at single Above to valve A10, outer tube sleeve 3 and the oil outlet 11 of note plug pipe 7, note plug pipe 7 lower end are communicated with the tube wall of note plug pipe 7 It is socketed in into oil jacket 8, enters the bottom of oil jacket 8 for enclosed construction, enters the side of oil jacket 8 and be provided with entering the oil-feed that the inside of oil jacket 8 is connected Hole 12, fuel feed hole 12 forms an oil suction chamber 20 to the bottom of oil jacket 8 is entered.Sealing ring 19 is provided between note plug pipe 7 and through hole 9, it is described Check valve A10 and check valve B18 be check valve that gas, liquid can be used.

It is described enter oil jacket 8 be made up of body 16 and plug nut 17, the lower end of body 16 is spirally connected with plug nut 17.It is described enter The upper end of body 16 of oil jacket 8 is spirally connected with the lower end of outer tube sleeve 6, it is described enter oil jacket 8 body upper end be provided with to be oriented to note plug pipe 7 and make Positioning sleeve 15, note plug pipe 7 lower end is socketed in into oil jacket 8 through positioning sleeve 15, and the body lower end for entering oil jacket 8 uses stifled Head nut 17 is closed, and the fuel feed hole 12 is arranged on the side of body 16 into oil jacket 8, and the fuel feed hole 12 is externally provided with filter screen 13, It is described enter the lateral surface of oil jacket 8 be provided with annular groove 14, fuel feed hole 12 is arranged on the bottom of annular groove 14, and filter screen 13 is arranged on annular In groove 14.

When using the utility model, downward fortune is continued in the control note plug of power section 2 lower end of pipe 7 after fuel feed hole 12 Dynamic, outer tube sleeve 6 can only be entered by noting plug pipe 7 by now entering the oil in oil jacket 8 positioned at the lower section of fuel feed hole 12, when oil is full of outer tube sleeve 6 and grease chamber 1 after the external world will be transported to by oil outlet 4, be now oil pumping state；When once oil pumping is completed, power section 2 Control note plug pipe 7 is when up moving, because check valve A10 and check valve B18 setting, the oil in note plug pipe 7 will not return into Oil jacket 8, the oil suction chamber 20 for now entering oil jacket 8 is in vacuum state, when note plug pipe 7 lower end continues up to move by fuel feed hole 12 When, influenceed by external atmosphere pressure, oil will enter oil jacket by fuel feed hole 12, now complete an oil pumping process, when The control note plug pipe 7 of power section 2 is when down moving again, oil may proceed to by note plug pipe 7, outer tube sleeve 6, grease chamber 1 be transported to it is outer Boundary, the control note plug pipe 7 of power section 2 is so moved repeatedly, can just continue to pump, whole oil pumping process will not be flowed by oil Property influence, the grease pump under low-temperature condition still have higher operating efficiency.

It the above is only preferred embodiment of the present utility model, not thereby limit patent protection model of the present utility model Enclose, the equivalent structure transformation that every utilization the utility model claims, explanation and accompanying drawing are made, be included in this practicality new In the protection domain of type.
