Abstract
The utility model solves the technical drawback of high manipulation strength and low service efficiency in the current mechanical jack or the manual operation of the supporing machine. A screw rod driven by a bipolar machine and a reducing gear box is positioned on the horizontal pivot of the parallel four-bar pedestal body, and the work power of the motor can derive from the motor vehicle power source. The technique has the advantages of wide use scope, convenience and high operation efficiency.
Description
Technical field
Of the present utility model is a kind of mechanical jack device that is used for the lifting body of motor vehicle.
Background technology
Jack is to support to erect a kind of lifting engine installation of lifting body of motor vehicle, particularly in operations such as replacing automobile tyre, uses more frequent.A class cyclecar jack wherein, generally adopted following structure: with parallel four connecting rods is the interlock main body, two connecting rod pivots of its level are the strong point of a leading screw, what the fulcrum in it adopted is leading screw screw connection structure, hinged support is as upper support point and ground supports point about in the of two in addition, and this class jack is called the frame machine usually again.Handgrip moves on hand rotating band movable wire thick stick and the upper support point after being connected with leading screw is coaxial, by changing the height of two hinge-points up and down, realizes the lifting of body of motor vehicle.This manual mode of operation, working strength is big, inefficiency, if the connection location of handgrip and jack main body then operates and just requires great effort more very infirm, and work efficiency is lower.
The utility model content
In order to overcome existing jack product because of fault of construction, cause its manipulation strength height, ineffective major technique disadvantage, the utility model patent application provides a cover electrodynamic type jack technical scheme for this reason, the major technique content of this technical scheme is: this electrodynamic type jack includes parallel four link body supports, the hinged support up and down of this main body rack is respectively as ground supports face and car body bearing surface, two horizontally hinged fulcrums cooperate fulcrum as the lateral rotation of leading screw in addition, wherein a normal-running fit fulcrum is a leading screw screw fit structure, the input gear of the reducing gearbox that the reducing gearbox output wheel of leading screw one end setting is provided with on reducing gearbox and either-rotation motor axle is in transmission connection, and the either-rotation motor power lead is connected into the car body power supply.
The technical solution of the utility model, changed the manual mode of operation of original jack heaviness, directly adopt power sources of motor vehicle, drive the leading screw rotation by drive of motor, force leading screw screw connection fulcrum wherein on leading screw, to move, thereby change the support distances of two fulcrums up and down of four connecting rods, lift on the realization automobile or the operation of falling, its use is very simple, and work efficiency also improves for this reason greatly, for the self-propelled vehicle handling labor provides convenience.The technical program is especially utilized the automotive battery power supply, as the machine operation power supply, so its use is not limited to.
Description of drawings
Fig. 1 is the external structure scheme drawing of this electrodynamic type jack
Fig. 4 is the connection structure scheme drawing of reducing gearbox
Fig. 2, Fig. 3 are respectively the leading screw connection structure scheme drawing of 2 horizontally hinged points.
The specific embodiment
As shown in the figure, the structure composition of this electrodynamic type jack includes parallel four link body supports 1, the last lower fulcrum of this main body rack 1 is respectively as ground supports face 10 and car body bearing surface 11, two horizontal fulcrum horizontally sets of this main body rack 1 leading screw 2, the connection mode of this two horizontal fulcrum and this leading screw 2 is: a fulcrum 13 and leading screw 2 bearing normal-running fiies, another fulcrum 14 is provided with the screw structure, cooperate with leading screw 2 leading screw screws, leading screw 2 outer ends are provided with reducing gearbox 3, the output gear of this reducing gearbox 3 is arranged on the leading screw 2, the gear wheel shaft 30 of the input gear 31 of reducing gearbox 3 is the output main shaft of either-rotation motor 4, and the power lead of either-rotation motor 4 links to each other with power sources of motor vehicle.
Claims (1)
1, a kind of electrodynamic type jack, include parallel four link body supports (1), the hinged support up and down of this main body rack is respectively as ground supports face (10) and car body bearing surface (11), two horizontally hinged fulcrums cooperate fulcrum as the lateral rotation of leading screw (2) in addition, wherein a normal-running fit fulcrum (14) is a leading screw screw fit structure, the input gear that it is characterized in that the reducing gearbox that reducing gearbox output gear that leading screw (2) one ends are provided with is provided with on reducing gearbox (3) and either-rotation motor axle is in transmission connection, and either-rotation motor (4) power lead is connected into the car body power supply.
