Abstract
The utility model relates to a jack-up type vehicle-mounted jack, a body comprises four supporting arms (1), an upper fixing table (2), a lower lifting table (3), a cross led screw (4) and a motor (5); the upper fixing table (2) is fixedly connected with an automobile beam, the lower lifting table (3) is opposite to the ground, and the four supporting arms (1) can form a deformable parallelogram, wherein the two supporting arms at left and right diagonal ends are pin-jointed by a pin shaft (6), and the two supporting arms at upper and lower diagonal ends are respectively pin-jointed to the upper fixing table (2) and the lower lifting table (3) by a pin shaft, and the cross led screw (4) is horizontally penetrated in the pin shaft (6) of the left and right opposite angles, the motor (5) is fixedly arranged at outer side of one pin shaft (6) and is linked with the cross led screw (4) by a linkage device; the jack does not need manual placement and has the advantages of high safety and simple and convenient operation.
Description
Technical field
The utility model relates to a kind of jack, particularly a kind of vehicle-mounted jack of installing with automotive frame of jack up.
Background technology
Traditional jack all is split structure designs, need during use from be positioned over the automobile boot, to take out, and creep into and it is placed back top lifting lifting at the bottom of the car and all need to operate with crank rocker, owing to car base space little being difficult for lays, owing to the danger of caving in that takes place easily to slide of top and automotive frame, it is big to have labour intensity in the use, and work efficiency is low, poor stability has the deficiency of using inconvenient and operating difficulties.Therefore, how to address the above problem, become problem demanding prompt solution.
Summary of the invention
The technical problems to be solved in the utility model provides and need not manually to lay operation, has the vehicle-mounted jack of jack up safe and simple to operation.
For solving the problems of the technologies described above, the vehicle-mounted jack of a kind of jack up of the present utility model, wherein this body comprises four hold-down arms, last fixed way, following bay-lift, cross lead screw and motor, describedly go up fixed way and automotive frame captive joint, time bay-lift is relative with ground, described four hold-down arms constitute deformable parallelogram, wherein about between the hold-down arm of two diagonal angle ends by the bearing pin pin joint, up and down two diagonal angle ends hold-down arm by bearing pin respectively pin joint connect and go up fixed way and following bay-lift; About described cross lead screw level is located in the bearing pin at two diagonal angles, motor fixedly installs therein the bearing pin outside by linkage and cross lead screw interlock.
The vehicle-mounted jack of above-mentioned jack up, described linkage are the gear reduction linkage; Drive the cross lead screw forward or reverse by motor transmission gear deceleration linkage.
The vehicle-mounted jack of above-mentioned jack up, described motor is electrically connected automobile power source for the 12V DC machine, and its master cock is arranged in the operator's compartment.Realize the lifting of direct convenience control jack.
The vehicle-mounted jack of above-mentioned jack up, it is mutually meshing to be respectively equipped with round-arced tooth about described up and down two diagonal angle ends between two hold-down arms.Increase between hold-down arm, go up more compact structure and stressed reasonable between fixed way and the following bay-lift.
The vehicle-mounted jack of above-mentioned jack up, described upward fixed way table top and automotive frame bottom surface are suitable, are provided with between them by the hoop-iron captive joint.
The vehicle-mounted jack of above-mentioned jack up, described linkage is provided with travel switch.
The utility model is owing to adopt technique scheme, be fixedly installed on the body of the dual-side of automotive frame, the cross lead screw axial limiting with the bearing pin of motor one side in, be spirally connected with the bearing pin of opposite side, by motor driven cross lead screw forward or reverse, the control cross lead screw makes four hold-down arms constitute deformable parallelogram and realizes cross directional stretch or compression, thereby drives bay-lift lifting down.When four hold-down arm horizontal compression, its bottom surface withstands on the ground back and oppositely makes fixed way and automotive frame rises, the purpose of realization jack-up during following bay-lift decline certain position.Work is when finishing, and when the hold-down arm cross directional stretch, last fixed way and automotive frame drop to automotive wheel and that fixed way is superimposed as one and does not influence running car on the final sum in bay-lift continues to make progress down behind the ground; Need not manpower work in the operation in the use and realize simple to operationly, guarantee the technique effect of safety operation.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is a kind of structural representation of the utility model specific embodiment;
