The invention relates to a portable dual-purpose hydraulic jack for vehicles. The technical scheme includes that a hydraulic jacking device of the jack is arranged on one side of a base, a mount is arranged on the other side of the base, an oil tank is arranged on one side of the mount facing the hydraulic jacking device, and a motor is mounted on the other side of the mount. The oil tank is made of elastic materials and in a 'concave' bag-type structure, a concave opening of the oil tank is clamped on a telescopic arm of the hydraulic jacking device, an opening end of the oil tank is hermetically fixed on the mount, an oil pump device is arranged in the oil tank, an oil inlet of the oil pump device faces the oil tank, both the mount and the base are provided with oil supply passages, one ends of the oil supply passages are connected with the oil pump device, and the other ends of the oil supply passages are connected to the hydraulic jacking device. The concave opening of the oil tank having the 'concave' bag type structure is clamped on the telescopic arm of the hydraulic jacking device, the problem about arrangement of the oil tank is solved, and meanwhile, the size of the oil tank is reduced due to the fact that the oil pump device is arranged in the oil tank directly.
Description
technical field [0001] The invention relates to a vehicle jack device. Background technique [0002] Car jacks generally adopt a hydraulic structure, and the jacking device of the jack is raised by manually controlling the hydraulic oil. This kind of jack generally has a bulky structure, is not easy to carry around, and is laborious to operate. Existing has occurred the electrohydraulic jack that adopts vehicle power socket to draw power supply. [0003] For example, the Chinese utility model patent (application number: 200620107377.8, application date: 2006-09-04) discloses an electric hydraulic jack for vehicles, which includes an oil source box and a motor connected to the oil source box, and an oil pump driven by the motor. and an oil cylinder with a piston rod, a one-way controllable valve is arranged between the oil pump and the oil cylinder, and a valve cavity is arranged on the one-way controllable valve, and the valve cavity includes an upper valve cavity and a low...
