The portable type quick lifting jack disclosed by the utility model has the beneficial effects that the cost (the raw material cost and the processing cost) is reduced, the processing is easy, the working efficiency is increased, the labor intensity is reduced, and the portable type quick lifting jack is more portable and practical.
Description
Technical field
The utility model is about vehicular spare parts, and in particular, the utility model relates to a kind of jack device.
Background technology
Known a kind of automobile convenient jack mainly makes the lifting of leading screw realization jack for the helical movement in the leading screw locknut with fixing by rotating threaded shaft.That described jack has advantages of is easy to carry with car, save the space, lifting is effective; Its deficiency is that stroke is long in the leading screw lifting process; Time-consuming, effort inefficiency, lead screw machining is uneconomical.
The utility model content
For above-mentioned prior art, the utility model provides a kind of can reach the fixing Portable fast lifting jack that is used for automobile by fast lifting.
In order to solve the problems of the technologies described above, the utility model is used for the technical scheme that the Portable fast lifting jack of automobile is achieved: comprise a pair of lower support arm and a pair of upper support arm, the upper end of described upper support arm is connected with back-up block, described lower support arm is connected with base, the junction of one end of described upper support arm and an end of described lower support arm is provided with supporting pin and locating dowel pin, the junction of the other end of the other end of described upper support arm and described lower support arm is provided with the leading screw locknut, run through a leading screw in described supporting pin and the leading screw locknut, the middle part of described leading screw is provided with the feed rod part, and the external diameter of described feed rod part is less than the internal diameter of leading screw locknut.
Compared with prior art, the beneficial effects of the utility model are:
1. reduce cost (feed stock cost and tooling cost), be easy to processing.
2. increase work efficiency.
3. reduce labor intensity.
4. make the lighter practicality of equipment.

The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
As depicted in figs. 1 and 2, the Portable fast lifting jack that the utility model is used for automobile comprises a pair of lower support arm 2 and a pair of upper support arm 5, the upper end of described upper support arm 5 is connected with back-up block 6, described lower support arm 2 is connected with base 1, the junction of one end of described upper support arm 5 and an end of described lower support arm 2 is provided with supporting pin 10 and locating dowel pin 11, the junction of the other end of the other end of described upper support arm 5 and described lower support arm 2 is provided with leading screw locknut 12, run through a leading screw 4 in described supporting pin 10 and the leading screw locknut 12, the middle part of described leading screw 4 is provided with feed rod part 8, and the external diameter of described feed rod part 8 is less than the internal diameter of leading screw locknut 12.Be fixed position with supporting pin 10 coupling ends on the described leading screw 4, the length of thread of this fixed part is shorter, and the coupling end with leading screw locknut 12 on the described leading screw 4 is the working position, and threaded portion 7 length of this working position are longer.
The utility model jack can form in the transformation of the way of the basis of existing scissor-like jack, as shown in Figure 1, the leading screw 4 of jack is processed into the two ends bracelet, and the middle part diameter is less than or equal to the smooth feed rod part 8 (its length is decided on ground Clearance or the general vehicle road clearance on different automobile types chassis) of screw thread root size (that is: leading screw locknut internal diameter); Threaded one end part 7 is long on the leading screw 4 finishes normal effectively lifting work for jack and uses, the other end can only be processed with shorter screw thread and pack up fixing using (this section screw thread generally is processed with the 5-6 button and gets final product) for realizing jack, and other parts all can remain unchanged.By being combined the landing hold-down arm with the leading screw locknut in the long buckle portion position of leading screw one end after the transformation of the way, to realize the lifting of jack, the feed rod part 7 of part is passed leading screw locknut 12 to reduce stroke in the middle of on the leading screw 4, minimizing flogs a dead horse, but Quick-speed jack, the short buckle portion position of the leading screw other end and leading screw locknut 12 in conjunction with or break away from, play also fixing jack of folding and unfolding.
During work, feed rod part 8 on the leading screw 4 is directly walked from leading screw locknut 12 and is crossed until reach the threaded portion 7 of leading screw 4 one ends (left end in the diagram), by threaded portion on the leading screw 47 and leading screw locknut 12 in conjunction with the lifting jack, otherwise descending jack, until leading screw locknut 12 is rotated feed rod part 8 to leading screw 4, leading screw 4 is walked from leading screw locknut 12, leading screw locknut 12 arrives the short thread position of leading screw 4 other ends (right-hand member in the diagram) fast, be combined with this short thread part by leading screw locknut 12, pack up and fixing jack.
Although the above is described the utility model in conjunction with figure; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that do not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the present utility model.
