Abstract
The utility model provides an electric or hand jack of a vehicle for a minicar (including a car) following a vehicle. A variable triangular bracket which is composed of a bracket 2 provided with an antiskid plate 1, an auxiliary bracket 3, a screw rod 4 and a screw nut 7 is provided with a carrier frame 8 which is vertical to the direction of movement of the screw nut 7. The stress end of the screw rod 4 is provided with a bearing 5 and is connected with a speed reducing mechanism 11 which is driven by a motor 10 or a handle assembly through an axle head at the stress end. The jack of the utility model can raise work efficiency, can reduce labor intensity and can improve operating conditions. The utility model has the advantages of simple structure, convenient use, high safety factor, sliding resistance, reliable performance, etc.
Description
The utility model relates to a kind of self-propelled vehicle with the jack that car uses, and particularly relates to the jack that a kind of mid-get car (comprising car) uses with car.
The jack great majority that at present domestic mid-get car (comprising car) uses with car are to adopt fluid pressure type or two kinds of structures of mechanical type, no matter how the driver must crawl under the car or squat down significantly and can operate the jack of these two kinds of structures spring, summer, autumn, winter climatic conditions in use.Not only operation inconvenience, causes a large amount of physical demandss at the clothes of easily making dirty, and that also gives the operator simultaneously healthyly brings harm.
The purpose of this utility model be to provide a kind of and can alleviate operator's physical demands significantly, improve working conditions, easy and simple to handle and do not influence healthy electricity, hand dual-purpose motor vehicle jack.
The technical solution of the utility model is as described below: this utility model comprises leading screw, screw, bearing, handle assembly, motor and speed reducer structure, and the support and assistant support, the leading screw that at one end are provided with checkered plate are formed a variable triangular supports jointly together with screw.On this variable triangular supports, be provided with the carriage vertical, and bearing be set, and the spindle nose by this stressed end connects one and realized by the speed reduction gearing of driven by motor or handle assembly in the force side of leading screw with the screw sense of motion.
The utility model is owing to taked carriage vertical with the screw sense of motion on the variable triangular supports and by the frame mode of spindle nose bonded assembly electric reducer structure and handle assembly, make this utility model can not only reliably realize electric operating and M/C, increase work efficiency, reduce operator's labour intensity, improve its service conditions, and have simple in structure, easy to use, can to each position of whole skirt support and non-slip, safety factor is high, advantages such as reliable working performance.Be that present domestic comparatively desirable self-propelled vehicle is with the car special tool.
In conjunction with the accompanying drawings the technical solution of the utility model is described in further details:
Fig. 1 is the electric structure scheme drawing of electricity, hand dual-purpose motor vehicle jack;
Fig. 2 is the handle assembly structural representation of electricity, hand dual-purpose motor vehicle jack.
By Fig. 1, electricity shown in Figure 2, hand dual-purpose motor vehicle jack, be one and be provided with support 2 assistant support 3 riveted joints identical that checkered plate 1, its transversal surface are flute profile with another shape by an end, on leading screw 4 close spindle nose parts, be with bearing 5 and bearing seat 6, bearing seat 6 is embedded the part that takes up of support 2 and assistant support 3 respectively together with bearing 5 and screw 7, and with leading screw 4 and screw 7 corresponding connections, make support 2, assistant support, 3 and leading screw 4 form a variable triangular supports.The end that embeds the assistant support 3 of screw 7 on this variable triangular supports is connected and fixed a carriage 8.This carriage 8 is provided with spill bar groove.Connect a speed reduction gearing 11 that drives by DC machine 10 or the handle assembly be made up of output shaft 9, crank 12 constitutes by the spindle nose of leading screw 4 through output shaft 9 again.
Be enclosed within on the spindle nose of leading screw 4 electronic, manual two-part output shaft 9 is corresponding respectively during use, it is meshing with each other.After the energized (this power supply can directly be introduced by Cigarette lighter in the operator's compartment or dc battery jar), motor 10 will drive speed reduction gearing 11 and by output shaft 9 leading screw 4 be rotated, and change distance between carriage 8 and the ground with a length of side that changes variable triangular supports.Cranker 12 is identical with 11 effects of electric reducer structure, and two kinds of frame modes all can reach the purpose that car body rises and falls.The utility model is owing to be provided with spill bar groove on carriage 8, skirt is stuck in this spill bar groove just, and inconvenience is moved, and with the set checkered plate 1 of ground contact portion, improves safety factor greatly in addition, and serviceability is further improved.
