Abstract
The utility model relates to an electric hydraulic jack which comprises a motor, an oil pump, a screw, a screw rod, check valves, a piston, an oil cylinder, etc. The utility model has the technical scheme that the side edge of an original vertical jack is provided with a DC motor and the oil pump which are coaxially configured by the screw, a high-pressure and a low-pressure oil paths are arranged in a base, a high-pressure and a low-pressure check valves are respectively arranged in both of the oil paths, the other side of the base is provided with an oil discharging valve, the inner part of the piston is provided with the screw rod and the outer part of the piston is provided with the oil cylinder. When the utility model is used, the DC motor is energized to rotate and drive the oil pump to run with high speed. The output of the oil pump drives the piston and the screw rod of the oil pump to move upwards to jack up a weight by the high-pressure oil path. When operated, the electric hydraulic jack has the advantages of labor saving, time saving and convenience.
Description
One, technical field
The utility model relates to various jacks, the automobile-used jack of specifically a kind of electric hydaulic.
Two, background technology
Present known jack has screw rod horizontal type jack, the vertical jack of screw rod, hydraulic jack etc.These jack one dishes are by base, support, mesh elevating screw with support by nut, the platform that contacts with supported material and constitute with the joining operating handle of elevating screw, but they are rising this jack or are falling and all adopt hand (or hand) to finish, so when operation, both time-consuming, require great effort again.Especially along with the popularizing of miniature car, it is more and more that the woman drives the people of roadlice, give women driver change trains tire bring more inconvenient.
Three, summary of the invention
At the shortcoming that above-mentioned original jack exists, the technical scheme of the utility model technical issues that need to address and proposition is to overcome the defective that prior art exists, and provides a kind of lifting more convenient, more time saving and energy saving electric hydaulic jack.
The utility model main technical schemes is: the side at former vertical jack is provided with DC machine (9) and oil pump (7), DC machine and oil pump arranged coaxial, motor is connected with screw (6) with oil pump, and oil pump (7) is connected by screw (5) with the vertical jack of former hydraulic pressure.Base (3) inside is provided with high-pressure oil passage (1) and low pressure oil circuit (2), and high-pressure check valve (8) and base pressure boiler check valve (4) respectively are set on high-pressure oil passage and base pressure oil circuit (2), at the base opposite side oil cock (10) is set.Screw rod (13) is equipped with in piston (11) inside, the outside oil cylinder (12) of installing of piston.
Advantage of the present utility model: drive oil pump (7) high-speed operation during DC machine (9) energising rotation, oil pump output enters oil cylinder (12) through high-pressure check valve (8) again by high-pressure oil passage (1), promote oil pump piston (11) upward movement, piston (11) is with screw rod (14) jack-up upwards, laborsaving saving time during operation, convenient especially.
Four, description of drawings
Fig. 1 is the utility model structure master cutaway view.
Among the figure 1, high-pressure oil passage; 2, low pressure oil circuit; 3, base; 4, low pressure check valves; 5, screw; 6, attaching screw; 7, oil pump; 8, high-pressure check valve; 9, motor, 10, oil cock; 11, piston; 12, oil cylinder; 13, screw rod.
Fig. 1 illustrates: the side of vertical jack is provided with a motor (9) and oil pump (7), motor is connected with screw (6) with oil pump, oil pump is connected by screw (5) with base (3), high-pressure oil passage low pressure oil circuit (2) is set on the base, be respectively equipped with high-pressure check valve (8) and low pressure check valves (4) in high-pressure oil passage and the low pressure oil circuit, be provided with oil cock (10) at opposite side.Screw rod (13) is equipped with in piston (11) inside, the outside oil cylinder (12) of installing.
Five, the specific embodiment
Below in conjunction with Fig. 1 the utility model implementation process is done step explanation: after motor (9) is switched on a flowing mode, drive oil pump (7) with in-oil cylinder oil, by high-pressure oil passage (1) input piston (10) bottom, rise thereby promote piston (10), drive the screw rod jack-up weight that rises simultaneously; When PTO Power Take Off stops motor (9) and oil pump (7), oil cock is unscrewed, piston is replied decline under the weight effect, make hydraulic oil get back to oil cylinder (12), jack is descended restore.The utility model is widely used in automobile-used jack and is used, and brings laborsaving save time and convenient to chaufeur transposing tire.
Claims (1)
1, a kind of electric hydaulic jack, it comprises DC machine, oil pump, screw, screw rod, boiler check valve, piston, oil cylinder, it is characterized in that one direct current motor (9) and oil pump (7) being set at the side of former vertical jack, DC machine and oil pump arranged coaxial, connect with screw (6), oil pump (7) is connected by screw (5) with former vertical jack, high-pressure oil passage (1) and low pressure oil circuit (2) are set in base (3), in two oil circuits, respectively establish high-pressure check valve (8) and low pressure check valves (4), at the base opposite side oil cock (10) is set, screw rod (13) is equipped with in piston (11) inside, and oil cylinder (12) is established in the piston outside.
