Abstract
The utility model relates to an integrated body of an electro-hydraulic jack. The integrated body is in the shape of a rectangular metal block having an internal structure. The internal structure comprises a piston cavity, a one-way valve cavity, oil holes and a motor shaft hole. The oil holes are oil transfer passages in the metal block and allow the cavities to be communicated or the cavities and the outside of the integrated body to be communicated; an oil circuit member allowing hydraulic oil to be transferred and capable of self-locking is formed. Meanwhile, the metal block ensures that the hydraulic oil is well cooled; the motor shaft hole penetrates the integrated body and opens at a plane of the same side of the integrated body with the oil holes connected with an oil pump, and a spot for direct installation of the motor and the oil pump is formed; the electro-hydraulic jack is compact in structure, and less oil is leaked from connections. The integrated body of the electro-hydraulic jack is reasonable in structure, the electro-hydraulic jack comprising the integrated body is compact in structure, leaking oil is effectively reduced, and the cooling problem of the hydraulic oil is improved.
Description
Technical field
The utility model belongs to jack field, especially a kind of electric hydraulic lifting jack integrated entity.
Background technology
Existing electric hydraulic lifting jack mostly is oil pipe and connects, and structure is scattered, is inconvenient to portably use, and leakage often appears in oil pipe junction, and hydraulic oil transmits in oil pipe, and high pressure causes the high temperature of hydraulic oil to be difficult for leaving, damage parts.
Summary of the invention
The purpose of this utility model is to provide a kind of electric hydraulic lifting jack integrated entity, and it is rational in infrastructure, the motor-driven jack close structure of composition, and effective less jack leakage also improves the heat dissipation problem of hydraulic oil.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of electric hydraulic lifting jack integrated entity, be shaped as the oil circuit body of cuboid, structure comprises plunger shaft, unidirectional valve pocket, oilhole and motor axis hole, plunger shaft and unidirectional valve pocket can be installed piston and check valve respectively, in integrated entity, the cavity of various functions is through the orderly connection of oil-through hole, make a complete oil circuit body of the inner formation of integrated entity, the leakage problem that the connection of minimizing part body produces, oil circuit body can be realized transmission and the oil circuit self-locking of motor-driven jack hydraulic oil, its integrated entity is the block of metal, the high temperature that hydraulic oil produces when internal transmission can better shed, motor axis hole is the through hole of mounted motor axle on integrated entity, motor axis hole connects integrated entity, be communicated with out with the plane of the oilhole that is connected oil pump in integrated entity the same side, formation is the position of mounted motor and oil pump directly, reduce the use of attaching parts, make the close structure of motor-driven jack, reduce the generation of leakage, easy to use and carry.
Advantage of the present utility model and good effect are:
A kind of electric hydraulic lifting jack integrated entity of the utility model, oil circuit and various cavity are integrated in derby, the installation of motor and oil pump is provided simultaneously on integrated entity, reduce connection structure, reduced motor-driven jack and the problem of leakage more due to point of connection, make motor-driven jack close structure, metal material provides the heat radiation in the work of internal hydraulic pressure oil simultaneously.
Accompanying drawing explanation
Figure l is outside drawing of the present utility model;
Fig. 2 is section-drawing of the present utility model.
The specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of electric hydraulic lifting jack integrated entity, it is shaped as the derby of cuboid, inner structure comprises plunger shaft 1, unidirectional valve pocket 2, oilhole 3 and motor axis hole 4, plunger shaft 1 is the cavity that piston can be installed in integrated entity inside, unidirectional valve pocket 2 is cavitys that check valve can be installed in integrated entity inside, oilhole 3 is oil transportation channels of integrated entity inside, by orderly each cavity of connection of oilhole 3, the inner formation of integrated entity can provide the oil circuit of hydraulic oil transmission, reduce the transom of motor-driven jack, reduced the generation of the jack junction phenomenon of leakage, and the metal material of integrated entity is hot good conductor, the heat during work of the loose internal hydraulic pressure oil of actv. row, motor axis hole 4 is through holes of mounted motor axle on integrated entity, be communicated with out with the plane of the oilhole that is connected oil pump in integrated entity the same side, formation is the position of mounted motor and oil pump directly, reduce the use of attaching parts, make the close structure of motor-driven jack, reduce the generation of leakage, easy to use and carry.
