Abstract
The utility model discloses a hydraulic jack belonging to the hydraulically mechanical and technical field and essentially solves the prior problems in which the jack cannot be laterally placed or reversed. The utility model comprises a hydro-cylinder, a piston, an oil pump, and an oil tank. An oil outlet which is communicated with an oil inlet of the oil pump and an oil return port which is communicated with the oil outlet of the hydro-cylinder are respectively arranged on the oil tank which is a closed soft body oil tank made of oil resistant material. The utility model is not only capable of being uprightly used like the ordinary jack, but also is capable of being laterally placed or reversed with extending the range of use and application field of the jack.
Description
Affiliated technical field
The utility model relates to the hydraulic machinery technical field, particularly a kind of hydraulic jack.
Background technology
The utility model patent application a few days ago, public offering, the hydraulic jack that uses, its fuel tank, oil pump, oil cylinder, piston is structure as a whole, therefore little with its volume, compact conformation, in light weight, advantage such as easy to carry is at oil, chemical industry, coal, metallurgical, the mine, automobile, shipping industry and large-scale loading and unloading, be used widely in fields such as transportation and the daily life, particularly as automobile, the driver's tool of trac. etc. is commonly used, but its maximum shortcoming is, at side or swing to when using, oil pump can not be drawn onto oil and cause the jack operational failure from fuel tank, and may cause that also fluid leaks outside, so uprightly use only, can not side or swing to use, limited its range of use, and the existing thruster that is suitable for side or swings to use, device is drawn on the top, its fuel tank, oil pump and oil cylinder, piston is a separation type, oil pump work mostly is electronic mode, during use, oil cylinder, piston is on the scope of operation, oil pump, fuel tank can be also can be outside the scope of operation on the scope of operation, be connected with pressure duct between the two, so volume is big, use inconvenience, cost is also higher, less in the scope of operation, under the space-constrained situation, it is more inconvenient to use.
Summary of the invention
For addressing the above problem, but the utility model provides a kind of side or swings to the hydraulic jack of use.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of hydraulic jack, comprise several parts of oil cylinder, piston, oil pump and fuel tank, have oil outlet that is connected with the oil pump oil inlet and the return opening that is connected with the oil cylinder oil outlet on the fuel tank, described fuel tank is a fully enclosed flexible oil tank.
Shell can be equipped with in the described flexible oil tank outside, its objective is to be beneficial to the protection flexible oil tank.
For conveniently making and being connected, the oil outlet that is connected with the oil pump oil inlet on the described flexible oil tank can be an oil outlet pipe, the return opening that is connected with the oil cylinder oil outlet can be an oil return pipe, the mode of communicating that oil outlet pipe and oil return pipe are connected with described oil pump oil inlet and oil cylinder oil outlet respectively is communicated with by a hollow joint for it, hollow joint one end is manufactured with screw thread and is threaded with described oil outlet or return opening, the other end is manufactured with band tapering joint and makes described oil outlet pipe or oil return pipe is inserted thereon, tighten with wiring the outside, can certainly adopt other the mode of tightening.Oil outlet pipe, oil return pipe also can adopt other known connection modes with being connected of oil pump oil inlet, oil cylinder oil outlet.
Described flexible oil tank is made by oil proof rubber or oil resistant plastics, its objective is in order to increase the service life of flexible oil tank.
Flexible oil tank is the airtight and gas of not leaving a blank behind the power fluid of packing into, backflow and discharge along with power fluid, flexible oil tank automatically expands or shrinks, even at side or swing to when using, oil pump also can suck power fluid in flexible oil tank, guarantee the normal operation of jack, therefore, the beneficial effects of the utility model are very obvious, and it not only can resemble ordinary jack that works upright the use, also can side or swing to use, enlarged the range of use and the application of jack.
