Oil filling pipe 1, oil tube 2, direct current generator 3, pedestal 4, reduction gear box 5, plunger 6, plunger connecting rod 6-1, plunger lining 7, oil filling pipe joint 8, output gear 9, Returnning spring 10, packing ring 11, seal ring 12, slide block 13, slider track 14, engaging gear 15, eccentric shaft 16, roller housing 17.
Embodiment
As Figure 1-3, Fig. 2 is an overall structure of the present utility model.Adopt structures such as direct current generator 3, pedestal 4, reduction gear box 5, direct current generator and reduction gear box all are contained on the pedestal, be provided with motor is transformed into reciprocating switching mechanism from rotatablely moving, be used for drive plunger, plunger reciprocating pump oil in the plunger lining is exported butter from oil filling pipe 1.Owing to adopt less one pole or the bipolar DC motor of volume, rotating speed of motor higher (10,000 turn left the right side) is slowed down by a reduction gear box, and slowing-down structure adopts worm and gear, especially can adopt the planetary gear speed-reduction structure, and volume is less.
Gear 15 of output gear engagement, engaging gear 15 is provided with an eccentric shaft 16, on eccentric shaft, put a roller housing 17, pedestal is provided with the sliding rail 14 of slide block 13 and slide block, slide block and plunger fix and with the plunger interlock, the integrated type sliding motion structure that the utility model adopts plunger and slide block to be linked to be with screw thread, roller housing is connected with slide block is active, constitutes to rotate and reciprocating switching mechanism.
The active linkage structure of roller housing and slide block has multiple mode: as shown in Figure 1 the simplest, the roller housing 17 of cover leans against on the slide block 13 on the eccentric shaft 16.Roller housing 17 drives slide block and plunger moves right, and by Returnning spring 10 slide block and plunger is resetted left.
The active linkage structure of roller housing and slide block: slide block is provided with oval or oblate shape hole, and eccentric shaft is inserted in this hole.
The active ways of connecting of roller housing and slide block also comprises: be connected with a connecting rod on roller housing, connecting rod and slide block have a bearing pin active fixing.
Cover upper gasket 11 and seal ring on plunger, packing ring 11 and seal ring are sealed in the position that plunger stretches out the plunger lining, are with Returnning spring on the plunger connecting rod 6-1, roof pressure slide block and plunger upper gasket 11.It is rubber washers that packing ring 11 adopts steel packing ring, seal ring 12, seals up plunger and lining.Slide block slides in slider track 14, and slider track is exactly the two side formation of pedestal, can the tracks of slide block be fixed by the flange or the loam cake of sidewall punching press.
Structure of the present utility model is to be driven reduction gear such as planetary pinion by direct current generator, and will rotatablely move and convert the linear reciprocating motion of plunger to, is pressed into oil pipe again after producing the pressure chamber that pump pressure pushes butter the plunger gasket end by the to-and-fro motion of plunger.Can the working pressure of grease gun satisfy user's usage requirement, key be grease gun the plunger motion parts structure whether rationally and normal.Roller promotion slide block by the eccentric position on the gear travels forward, and is placed in the motion backward that the outer Returnning spring of plunger has guaranteed slide block, whole to-and-fro motion balance, steady.The utility model parts depreciation is little, and the slide block movement resistance is little, so the pressure loss is also little, and this structure guarantees grease gun stablizing of the value of keep-uping pressure during use, and guarantees that grease gun uses for a long time.
Rubber washer around Returnning spring roof pressure slide block and the plunger guarantees that slide block normally resets and the oil tight effect of plunger to-and-fro motion.The scroll wheel of the fine control eccentric shaft of slide block energy of upper sealing type is play up and down, continues to guarantee that creep does not take place when surge pressure grease gun.Simple in structure, motion is reasonable, high working efficiency, safety, reliable.The operating voltage that is suitable for all can at the 12-48 volt.
Eccentric shaft is as overlapping roller housing on the described gear, directly is abutted against with slide block or active the connection also is embodiment.
