Abstract

The invention relates to an electric driving and hand operating dual-purpose jack, which comprises a bracket and a lead screw, and one end of the lead screw is connected with the bracket through a moveable nut, and the end point of the lead screw is provided with a crank handle interface. The invention is characterized in that the invention further comprises a motor, a reducer, an eccentric cam and two reverberatory force springs. The reducer and the motor are coaxially connected with each other, and the transmission gear and the reducer are coaxially connected with each other, and the transmission gear is meshed with the clutch gear. The clutch gear is sleeved on the lead screw through the lead screw shaft pin. A back spring is arranged between the clutch gear and the crank handle interface. The other surface of the clutch gear is provided with the eccentric cam and is provided with a rotating handle. Two ends of the lead screw have no threads and are connected with the reverberatory force springs. The electric driving and hand operating dual-purpose jack not only realizes the electric driving lifting of the jack, but also can be lifted by had operation, which saves time and force when the car is changing the tyre or in maintenance.

Description

The electric-hand driven two-purpose jack
Technical field
The present invention relates to a kind of jack.
Background technology
Employed jack on the present known automobile has screw rod horizontal type jack, the vertical jack of screw rod, hydraulic jack etc.Generally comprise base, support, with support on nut ingear elevating screw, the operating handle that is connected with elevating screw etc., but when using such jack to Vehicle tyre mounting or dismounting and maintenance, its lifting all adopts hand (or hand) to finish, so it is time-consuming extremely to require great effort when changing tire and maintenance to automobile, popularizing particularly along with the small-sized household automobile, Tourism development under the situation of field and bad weather, is carried out Vehicle tyre mounting or dismounting and maintenance trouble especially.
Summary of the invention
Technical matters to be solved by this invention provides a kind of electronic, dual-use manual jack.
Electric-hand driven two-purpose jack of the present invention comprises support, screw mandrel, screw mandrel one end is by traveling nut and support socket, the end points of screw mandrel has the wind interface, it is characterized in that also comprising motor, retarder, eccentric wheel and two return springs, retarder is connected with motor coaxle, transmission gear links to each other with retarder is coaxial, transmission gear also meshes with clutch gear, clutch gear is connected on the screw mandrel by the screw axis guide, be socketed with retracing spring between clutch gear and the wind interface, another side at clutch gear has eccentric wheel, and have a turning handle, the screw mandrel two ends do not have screw thread and connect return spring, retarder, transmission gear, clutch gear, eccentric wheel, retracing spring is installed in the casing, and the other end of support is connected with casing.
Principle of work of the present invention is such: drive retarder when electrical power rotates, by transmission gear, drive clutch gear and make the positive and negative rotation of screw mandrel, realize the lifting of support.When the needs hand-operated lifting, rotate eccentric wheel clutch gear and transmission gear are broken away from, and clutch gear disengaging screw mandrel pivot pin, use the wind on the wind interface to make the positive and negative rotation of screw mandrel, can realize hand-operated lifting.It is for when jack rises or descend that the screw mandrel two ends do not have screw thread, prevents that the continuous rotating of motor from causing jack to damage; On the other hand, when restarting motor use jack, though the two ends of screw mandrel do not have screw thread, return spring is just in time given antagonistic force of screw mandrel, and screw mandrel and traveling nut are in time meshed, and jack is descended or rising.
This electric-hand driven two-purpose jack had both been realized the electric up-down of jack, again can hand-operated lifting, save time especially when making automobile change tire and maintenance, laborsaving.
