Abstract
The utility model discloses a kind of hydraulic jack, primarily of Hydraulic Pump, piston cylinder and oil cylinder composition, be connected by pipeline A between Hydraulic Pump with piston cylinder, be connected by pipeline B between Hydraulic Pump with oil cylinder, be connected by pipeline C between piston cylinder with oil cylinder, described pipeline A and pipeline B is respectively equipped with oil sealing chamber, oil sealing is provided with bead in chamber, the small ball's diameter is greater than the diameter of pipeline A or pipeline B, described pipeline C is provided with spill valve, the utility model adopts the design of oil sealing chamber and bead, make Hydraulic Pump can only pump in oil cylinder and can only be pushed in piston cylinder by oil in the course of the work, thus oil is continuously sent in piston cylinder in oil cylinder, after completing lifting task, opening spill valve can let out in oil return cylinder by oil, easy and simple to handle, safe and reliable.
Description
Technical field
The utility model relates to a kind of jack.
Background technology
Jack plays very important effect in modern industry application, it can support the sizable object of weight, but due to some extraordinary circumstances, jack needs to support weight longer a period of time, and some special jacks can complete such task, but owing to supporting weight for a long time, piston extension spring is shaped, after withdrawing under weight, piston substantially cannot return, causes jack to be scrapped.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of hydraulic jack.
In order to solve the problems of the technologies described above, the utility model provides a kind of hydraulic jack, form primarily of Hydraulic Pump, piston cylinder and oil cylinder, be connected by pipeline A between Hydraulic Pump with piston cylinder, be connected by pipeline B between Hydraulic Pump with oil cylinder, be connected between piston cylinder with oil cylinder by pipeline C, described pipeline A and pipeline B is respectively equipped with oil sealing chamber, oil sealing is provided with bead in chamber, and the small ball's diameter is greater than pipeline A(4) or the diameter of pipeline B.
As further improvement of the utility model, described pipeline C is provided with spill valve.
Adopt said structure, its beneficial effect is: the utility model adopts the design of oil sealing chamber and bead, make Hydraulic Pump can only pump in oil cylinder and can only be pushed in piston cylinder by oil in the course of the work, thus oil is continuously sent in piston cylinder in oil cylinder, after completing lifting task, opening spill valve can let out in oil return cylinder by oil, easy and simple to handle, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hydraulic jack.
In figure: 1-Hydraulic Pump, 2-piston cylinder, 3-oil cylinder, 4-pipeline A, 5-pipeline B, 6-pipeline C, 7-oil sealing chamber, 8-bead, 9-spill valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, a kind of hydraulic jack, form primarily of Hydraulic Pump 1, piston cylinder 2 and oil cylinder 3, be connected by pipeline A4 between Hydraulic Pump 1 with piston cylinder 2, be connected by pipeline B5 between Hydraulic Pump 1 with oil cylinder 3, be connected by pipeline C6 between piston cylinder 2 with oil cylinder 3, described pipeline A4 and pipeline B5 is respectively equipped with oil sealing chamber 7, be provided with bead 8 in oil sealing chamber 7, bead 8 diameter is greater than the diameter of pipeline A4 or pipeline B5, and described pipeline C6 is provided with spill valve 9.
During use, first spill valve 9 is locked, operation Hydraulic Pump is pumped and send oil, during oil pumping, in the oil sealing chamber 7 of pipeline B, bead 8 rises with hydraulic oil, open accent, hydraulic oil is made to enter in Hydraulic Pump 1, bead 8 in the oil sealing chamber 7 of simultaneously pipeline A props up accent, prevent leakage of oil, otherwise, during force feed, hydraulic oil can only enter piston cylinder 2 from Hydraulic Pump 1, constantly 1 pressure is taken out through Hydraulic Pump, oil constantly arrives piston cylinder 2 from oil cylinder 3 through pipeline B and pipeline A, thus make piston increase, jack-up weight, after completing lifting task, open spill valve 9, oil is let out in piston cylinder 2 be back in oil cylinder 3.
Any employing and the similar hydraulic jack designed by technical characteristic of the utility model will fall within protection domain of the present utility model.
Claims (2)
1. a hydraulic jack, form primarily of Hydraulic Pump (1), piston cylinder (2) and oil cylinder (3), by pipeline A(4 between Hydraulic Pump (1) with piston cylinder (2)) be connected, by pipeline B(5 between Hydraulic Pump (1) with oil cylinder (3)) be connected, by pipeline C(6 between piston cylinder (2) with oil cylinder (3)) be connected, it is characterized in that: described pipeline A(4) and pipeline B(5) be respectively equipped with oil sealing chamber (7), be provided with bead (8) in oil sealing chamber (7), bead (8) diameter is greater than pipeline A(4) or pipeline B(5) diameter.
2. a kind of hydraulic jack according to claim 1, is characterized in that: described pipeline C(6) be provided with spill valve (9).
