Abstract
The utility model relates to a motor hydraulic pressure jack which consists of a frame base, a double-section jacking cylinder, a hydraulic pressure oil pump and an oil tank. The bottom of the frame base is provided with an oiling hole of hydraulic pressure oil. The oiling hole is provided with the rapid connecting joint of an oil tube. The hydraulic pressure oil pump is driven by an engine arranged on a vehicle. The hydraulic pressure oil pump is connected with the oiling hole of the hydraulic pressure oil on the bottom of the frame base through a high pressure soft tube. A control valve is arranged on the connecting part of the hydraulic pressure oil pump and the high pressure soft tube. A manual oil pump is no longer used for jacking the jack. The motor hydraulic pressure jack can be used safely, reliably, conveniently and rapidly.
Description
Affiliated technical field
The utility model belongs to the driver's tool that uses on a kind of self-propelled vehicle, is the hydraulic jack that uses on a kind of self-propelled vehicle specifically.
Background technology
Jack is driver's tool indispensable on the automobile, and is essential when vehicle runs into fault, changing of tire.Dilly generally uses lifting screw, and full size vehicle then will use the bigger hydraulic jack of bearing capacity, but common hydraulic jack all is a type hand, needs manually slowly jack-up, uses very trouble inconvenience.And the leather cup of manual hydraulic oil pump very easily damages, and causes and can't use or bad use.
Summary of the invention
The utility model is exactly at a kind of motor-driven hydraulic jack of the shortcoming design-calculated of prior art, and easy to use reliable, jack-up speed is fast.
The technical scheme that its technical matters that solves the utility model adopts is: use the driving engine on the self-propelled vehicle to drive hydraulic oil pump, replace traditional hand oil pump.The motor-driven hydraulic jack of design-calculated, form by support, double-joint type jack-up cylinder body and hydraulic oil pump and fuel tank, the hydraulic oil oil hole is arranged at the support bottom, the oil pipe fast connector is housed on the oil hole, the hydraulic oil pump dress is driven by driving engine onboard, hydraulic oil pump is connected with high pressure hose with the hydraulic oil oil hole of support bottom, and control cock is equipped with in hydraulic oil pump and high pressure hose junction.
The beneficial effects of the utility model are, do not re-use hand oil pump jack-up jack, and are safe and reliable, convenient, fast.Having on the self-propelled vehicle of cylinder system, can directly on oil outlet, add cartridge control valve, connecting, using its hydraulic efficiency gear to drive jack with high pressure hose.Can install hydraulic efficiency gear additional for the self-propelled vehicle that does not have cylinder system uses.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Maker hydrodynamic pressure jack, form by support 1, double-joint type jack-up cylinder body 2,3 and hydraulic oil pump 6 and fuel tank 5, hydraulic oil oil hole 9 is arranged at support 1 bottom, oil pipe 8 fast connectors are housed on the oil hole 9, hydraulic oil pump 6 dresses are driven by driving engine onboard, hydraulic oil pump 6 is connected with the hydraulic oil oil hole 9 usefulness high pressure hoses 8 of support 1 bottom, and hydraulic oil pump 6 is equipped with control cock 7 with high pressure hose 8 junctions.During use, put jack well, connect high pressure hose 8.Can make jack stand by control cock 7.Finish using, can make hydraulic oil return fuel tank 5 by adjusting control valve 7, double-joint type jack-up cylinder body 2,3 is return under gravity and extension spring effect.
