Abstract
The utility model discloses an automobile convenient fast elevating jack, which comprises a pair of lower bracing arms and a pair of upper bracing arms, upper ends of the upper bracing arms are connected with a supporting shoe, the lower bracing arms are connected with a base seat, a supporting pin and a positioning pin are arranged at the connecting part of one end of each upper bracing arm and one end of each lower bracing arm, a leading screw locknut is disposed at the connecting part of the other end of each upper bracing arm and the other end of each lower bracing arm, a leading screw penetrates through the supporting pin and the leading screw locknut, a plain shaft part is arranged at the middle part of the leading screw, and the outside diameter of the plain shaft part is smaller than the inside diameter of the leading screw locknut. The connecting end of the supporting pin on the leading screw is a fixed part, and the connecting end of the leading screw locknut on the leading screw is a working part.
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 portable 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 is easy to carry with car, save space, the effective advantage of lifting; Its deficiency is that stroke is long in the leading screw lifting process; Time-consuming, effort inefficiency, leading screw processing is uneconomical.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can reach fixing automobile portable fast lifting jack by fast lifting.
The purpose of this utility model is achieved by following technical proposals: it comprises 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.
The beneficial effects of the utility model are: 1. cost-cutting (feed stock cost and tooling cost) is easy to processing.2. increase work efficiency.3. reduce labor intensity.4. make the lighter practicality of equipment.
Description of drawings
Fig. 1 is the front view of the utility model automobile portable fast lifting jack structure;
Fig. 2 is the birds-eye view of jack shown in Figure 1.
Specific embodiments
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The explanation of main parts size and details in the accompanying drawing: 1 base, 2 lower support arms, 3 leading screw locknuts, 4 leading screws, 5 upper support arms, 6 back-up blocks, 7 threaded portions, 8 feed rod parts, 9 stoppers, 10 supporting pins, 11 locating dowel pins, 12 leading screw locknuts.
As depicted in figs. 1 and 2, the utility model automobile portable fast lifting jack 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 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 (its length is decided on the 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 short 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.Long button position by leading screw one end after the transformation of the way combines the landing hold-down arm with the leading screw locknut, to realize the lifting of jack, the feed rod part 7 of centre portion is passed leading screw locknut 12 to reduce stroke on the leading screw 4, minimizing flogs a dead horse, but fast lifting jack, the short button position of the leading screw other end combines with leading screw locknut 12 or breaks away from, and plays 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 the threaded portion 7 that reaches leading screw 4 one ends (left end in the diagram), 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 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, combine with this short thread part by leading screw locknut 12, pack up and fixing jack.
Claims (2)
1. automobile portable fast lifting jack, 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, it is characterized in that, 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.
