Abstract
The utility model relates to a hand-operated and electric jack for automobile. The prior four-connecting rod type jack structure of the hand-operated automobile is additionally provided with a worm reducer 11 with a direct current motor, a drawing block 10, a quick folding bolt 16, and a phase-change switch 13 for implementing motor-driven purpose. The worm reducer 11 with a direct current motor is tightly fixed on the jack via the quick folding bolt 16. The drawing block 10 is connected with the fork 8 of the prior jack for conveying the driving force. When working, the plug 14 of a direct current motor is inserted with the power supply of the automobile; the phase-change switch 13 is operated for controling the normal-reverse transfer of the direct current motor. The drawing block 10 drives the fork 8 for the normal-reverse transfer after the deceleration and reinforcement of the worm reducer. The quick electric lifting and the reinforcement of the jack can be implemented. When hand operation is needed, the quick folding bolt 20 is loosened and the worm reducer 11 with the direct current motor is disconnected. One edge of the hook of the crank handle inside of the prior hand-operated jack passes through the fork 8, and the handle is rotated for implementing manual lifting and reinforcement.
Description
Technical field
The utility model relates to a kind of torch two electrical automobile jacks, and specifically a kind of automobile change of wheels that is used for can manually again can electrically operated jack.
Background technology
At present, all automobiles all are equipped with manual jack exercising the way because of the tire flat change of wheels or a jiao of the jack-up automobile when needing dress folding wheel of servicing a car to be used for automobile, a kind of manual jack is realized the lifting of jack with hydraulic drive, this jack thrust is bigger, but volume is also bigger, is not easy to roadlice and carries; Another kind of manually jack is realized reinforcement and lifting by four connecting rod swings, abbreviate four link type jacks as, this jack is by the seat of honour, band tooth boxed rod, band tooth lower link, swivel pin, axis, fork, screw rod, base is formed, two swivel pins are connected the band increment of two band tooth boxed rods on the seat of honour, two swivel pin is connected the band increment of two band tooth lower links on the base in addition, the tooth portion of two pairs of connecting rods is staggered to be interlocked, two anodontia ends of axis difference connecting band tooth upper and lower strut, band fork screw rod passes axis two cross-drilled holes and is fixed on the axis two and is threaded with the horizontal screw of axis one, rotate fork with crank and drive the screw rod rotation, screw rod will be relatively produces longitudinal travel with the axis of horizontal screw, thereby regulate the distance of two axis, swing connecting bar, upper and lower strut makes four connecting rods pivot angle unanimity when swinging up and down in the tooth portion cooperation of seat of honour base, left-right symmetric, the seat of honour realize horizontal lifting, and mechanism realizes reinforcement, this jack has minimum altitude little, the advantage that lift is big is widely used on the roadlice, but shortcoming is to need certain muscle power of cost and time to be used to shake the position of screw rod and adjustment jack, when the enterprising line operate of express highway, the operating time, long meeting increased dangerous.
Summary of the invention
The purpose of this utility model provide a kind of both can be with existing four link type M/Cs, again can be with the faster more labour-saving of electric operating torch two electrical automobile jacks.
The utility model be achieved in that the manual jack of four link type have the axis both ends of the surface of fork one end make and wear screw rod the cross-drilled hole parallel axes boss and load onto fast folding bolt, pulling block is loaded onto on the output shaft of a retarder that connects as one with two trough of belt connecting straps and with DC motor, do on the two trough of belt connecting straps of this retarder and be parallel to reducer output shaft and width and the consistent elongated slot of axis 2 boss width, retarder two trough of belt connecting strap elongated slots are docked simultaneously pulling block dock the back that puts in place and clamps fast with rolling over bolt soon with the boss of jack axis with the fork of jack, the attaching plug of DC motor is inserted on the power supply of automobile, the phase-change switch of operation DC machine drives the fast lifting that the fork rotating realizes jack with pulling block after just can controlling the DC motor rotating and passing through the retarder deceleration force amplifier, reach quick labour-saving purpose, to reduce the danger of on express highway, carrying out the change of wheels operation.While is because this jack is that torch two is moving, but at high speed unclamps fast folding bolt under the situation of vehicle battery power deficiency, removes the retarder implementation M/C of band DC motor, and guaranteeing under any circumstance can change of wheels.
