Description
Technical field:
The utility model relates to a kind of jack, relates in particular to be with electrically operated jack.
Background technology:
Traditional vehicle-mounted jack is divided into machinery and two kinds of hydraulic pressure, all needs the human hand to go to shake the purpose that just can reach lifting, and certain technical requirements is arranged, and safety factor is lower; The less people of arm strength uses painstakingly, large-scale jack general vehicle can not be equipped with, once vehicle in the process of moving damaged tyres need to change, perhaps the chassis needs little repairing, the somebody can only seek help from professional repairman, does not have the foreign aid and the little people of arm strength can only wait for relief under some particular surroundingss.
The utility model content:
The purpose of this utility model provides the vehicle-mounted jack in a kind of labour-saving, and it can allow the less people of arm strength like a cork motor tire be changed, and car chassis is carried out little repairing, and its simple in structure, dependable performance is safe in utilization, convenient.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of mechanical jack 1, reversing motor 2, direction switch 3, power lead 4, mechanical jack 1 links to each other with reversing motor 2, direction switch 3 is arranged on the reversing motor 2, power lead 4 is connected to reversing motor 2 inside, threaded spindle is divided into to be had threaded portion 5 and not to have threaded portion 6 to be connected with the reversing motor rotor shaft, screw thread spider 7 matches with threaded spindle, and power lead 4 can be connected with automotive battery by power folder or other instrument are installed.
Principle of the present utility model is to drive the threaded spindle rotation that mechanical jack links to each other with reversing motor by reversing motor, drive the spider that matches with the mechanical jack threaded spindle to threaded spindle two end motions by mechanical jack threaded spindle rotation, so reach the effect of lifting machinery jack.
The utility model has the advantages that its simple in structure, dependable performance, safe in utilization, convenient.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, the utility model specific embodiment is by the following technical solutions: it is by mechanical jack 1, reversing motor 2, direction switch 3, power lead 4 is formed, mechanical jack 1 links to each other with reversing motor 2, direction switch 3 is arranged on the reversing motor 2, power lead 4 is connected to reversing motor 2 inside, the threaded spindle of mechanical jack 1 is divided into to be had threaded portion 5 and not to have threaded portion 6, there is not threaded portion 6 to be connected with the reversing motor rotor shaft, screw thread spider 7 has threaded portion 5 to match with threaded spindle, and power lead 4 can be connected with automotive battery by power folder or other instrument are installed.
Principle of the present utility model is to drive the threaded spindle rotation that mechanical jack links to each other with reversing motor by reversing motor, drive the spider that matches with the mechanical jack threaded spindle to threaded spindle two end motions by mechanical jack threaded spindle rotation, so reach the effect of lifting machinery jack.
