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, pipeline A and pipeline B is respectively equipped with check valve A and check valve B, check valve A can only open towards piston cylinder direction, check valve B can only open towards Hydraulic Pump direction, described pipeline C is provided with control cock, the utility model utilizes the effect of check valve, Hydraulic Pump is made to pump in oil cylinder and can only be pushed in piston cylinder by oil, thus oil is continuously sent in piston cylinder in oil cylinder, after completing lifting task, opening control cock 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 check valve A and check valve B, check valve A can only open towards piston cylinder direction, and check valve B can only open towards Hydraulic Pump direction.
As further improvement of the utility model, described pipeline C is provided with control cock.
Adopt said structure, its beneficial effect is: the utility model utilizes the effect of check valve, Hydraulic Pump can only be pumped and can only be pushed in piston cylinder by oil in oil cylinder, thus oil is continuously sent in piston cylinder in oil cylinder, after completing lifting task, opening control cock 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-check valve A, 8-check valve B, 9-control cock.
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 A(4) and pipeline B5 be respectively equipped with check valve A7 and check valve B8, check valve A7 can only open towards piston cylinder 2 direction, and check valve B8 can only open towards Hydraulic Pump 1 direction, and described pipeline C6 is provided with control cock 9.
During use, first control cock 9 is locked, operation Hydraulic Pump is pumped and send oil, and due to the effect of check valve A, check valve B, 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, opens control cock 9, oil is let out in piston cylinder 2 to be back in oil cylinder 3, and oil return speed can be controlled by control cock 9.
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.
