The specific embodiment
Referring to Fig. 1～Fig. 5, the utility model comprises driver train B and lifting structure A, and driver train B comprises manual rocking handle 4, speed reduction gearing, drive motor 1 and output screw 9.Manually the power take-off shaft of rocking handle 4 and drive motor 1 is in transmission connection by speed reduction gearing and output screw 9, is conventional being in transmission connection between output screw 9 and the lifting mechanism A.Lifting mechanism A also is a conventional structure: the top of two lifting arms 10 is hinged, and the bottom has screw to screw in output screw 9, and output screw 9 has the opposite screw thread of two parts rotation direction, and the two ends rotational support is on frame.
Described speed reduction gearing comprises electronic driving gear 2, manual driving gear 5, one-level driven gear 3, secondary driving gear 8 and secondary driven gear 7, and electronic driving gear 2 is connected the axle of described motor 1 and goes up and mesh with one-level driven gear 3.Secondary driving gear 8 and one-level driven gear 3 be coaxial be connected and with 7 engagements of secondary driven gear, the coaxial connection of an end of this secondary driven gear 7 and described output screw 8.Described manual driving gear 5 and described one-level driven gear 3 engagements, an end of the axle of this manual driving gear 5 is connected with described manual rocking handle 4.Above-mentioned each gear is installed in the drop-gear box 11.
Electric power loop at described drive motor 1 is connected with the master cock of controlling ascending, descending and stopping, this master cock can be a travel switch 13, the trip switch 13 is installed in lifting arm 10 belows of described lifting mechanism near the middle part, when the lower end of two lifting arms 10 was arrived to a certain degree near (being elevation process) mutually, lifting arm 10 triggered the power supply that travel switches 13 cut off motors 1.
Described master cock also can adopt hand switch or teleswitch, is routine techniques.
Principle of work of the present utility model is: can insert the square shaft end of gear 5 with 4 the square hole of manually shaking the hand, drive one-level driven gears 3 by gear 5 and rotate, or drive one-level driven gears 3 by motor 1 and gear 2 and rotate.The gear 5 and 2 the number of teeth are less than one-level driven gear 3, carry out one-level and slow down.One-level driven gear 3 drives secondary driven gear 7 by the secondary driving gear coaxial with it 8 and rotates, and carries out double reduction.Secondary driven gear 7 drives output screw 9 again and rotates, and the latter drives lifting mechanism A work.
The utlity model has following characteristics:
1. under situation without external power supply, directly insert in 12 volts of power supplys of automobile and directly just can operate, more time saving and energy saving than oldfashioned hand jack, easy to use.
2. its speed reduction gearing is simple and reasonable for structure, and stable performance is not fragile, easy to carry.
3. just in case can also not work with hand mode when having electricity or motor to go wrong, and hand strength is more laborsaving than original.
