Abstract

The utility model discloses a portable jack for an automobile. The portable jack comprises a pair of lower supporting arms and a pair of upper supporting arms. The upper ends of the upper supporting arms are connected with a supporting block, the lower ends of the lower supporting arms are connected with a base, one lower end of the upper supporting arms is connected with one upper end of the lower supporting arms, a supporting pin and a locating pin are arranged at the connection position, a lead screw nut is arranged at the connection position between the other ends, a lead screw penetrates through the supporting pin and the lead screw nut, a polished bar portion is arranged in the middle of the lead screw, and the outer diameter of the polished bar portion is smaller than the inner diameter of the lead screw nut. Compared with the prior art, raw material cost and processing cost are reduced, work efficiency is improved, labor intensity in a using process is reduced, and the jack is light and practical.

Description

Portable jack
Technical field
The utility model relates to automobile and uses the jack field.
Background technology
Known automobile portable jack mainly makes the leading screw motion of spinning in the leading screw locknut realize that the lifting of jack is with fixing by rotating threaded shaft.The advantage that described jack has is easy to carry with car, save the space, but its weak point is that stroke is long in the leading screw lifting process, wastes time and energy, inefficiency, and leading screw processing is uneconomical.
The utility model content
(1) technical matters that will solve
At above-mentioned prior art deficiency, the utility model designed a kind of can fast lifting and the fixing portable jack that is applicable to automobile.
(2) technical scheme
For solving the problems of the technologies described above, a kind of portable jack that is used for automobile is provided, 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, and described lower support arm lower end 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, and 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.
Described leading screw and supporting pin coupling end are fixed position, and the length of thread of this fixed position is shorter, and the coupling end with the leading screw locknut on the described leading screw is the working position, and the threaded portion length at this position is longer.
(3) beneficial effect
The utility model has compared with prior art reduced feed stock cost and tooling cost, and work efficiency is provided, and alleviates the labour intensity in the use, makes the lighter practicality of jack.
Description of drawings
Fig. 1 is the portable jack structural representation according to the utility model embodiment;
Fig. 2 is the portable jack local structure scheme drawing according to the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is done into to describe in detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As illustrated 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, and the upper end of described upper support arm 5 is connected with back-up block 6, and described lower support arm 2 is connected with base 1.
One section junction of one end of described upper support arm 5 and described lower support arm 2 is provided with supporting pin 10 and locating dowel pin 11, and 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.
Described leading screw 4 is a fixed position with supporting pin 10 coupling ends, and the length of thread of this fixed position 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 at this position are longer.
Above-mentioned jack can be changed a social system on the basis of existing scissors-type jack and form, 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 of screw thread root size (that is: leading screw locknut internal diameter), and its length is ground Clearance on different automobile types chassis or general vehicle road clearance and decide; What leading screw 4 the preceding paragraph threaded portions 7 were long finishes normal effectively lifting work usefulness for jack, and the other end can only be processed into than the short thread part, packs up fixing usefulness for realizing jack, generally has the 5-6 button to get final product, and miscellaneous part all can remain unchanged.
During work, feed rod part 8 on the leading screw 4 is directly walked and mistake from leading screw locknut 12, until the threaded portion 7 that arrives leading screw 4 one ends, combine the lifting jack by threaded portion 7 on the leading screw 4 and leading screw locknut 12, otherwise decline jack, until the feed rod part 8 that leading screw locknut 12 is rotated to leading screw 4, leading screw 4 is from leading screw locknut 12 heavy losses property, leading screw locknut 12 arrives the short thread position of leading screw 4 other ends fast, combine with this short thread part by leading screw locknut 12, pack up and fixing jack.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
