Abstract
The invention provides a novel screw jack mechanism which consists of a base, a threaded sleeve, a weight-lifting screw rod sleeve, a weight-lifting screw rod, a large flange, a small flange, a small flange blind hole and a large flange blind hole. The structure consists of the hollow weight-lifting threaded sleeve with outer thread and inner thread on the threaded sleeve and the weight-lifting screw rod with outer thread. Thus, the weight-lifting screw rod sleeve and the weight-lifting screw rod can eject out the threaded sleeve to play a part in weight lifting, and due to the structure, the heights of the weight-lifting screw rod and the weight-lifting screw rod sleeve, which are descended to be withdrawn in the threaded sleeve are about 1/3 of the height of the common threaded jack, so that the height is low.
Description
Technical field
The present invention relates to a kind of lifting screw mechanism, particularly a kind of novel lifting screw mechanism belongs to the hardware & tools technical field.
Background technology
Lifting screw is that the act instrument is pushed up in a kind of use simple in structure widely; At present; Mostly lifting screw is that a joint screw thread bush adds the structure of a joint weight lifting screw rod; The height of the lifting screw of a this joint weight lifting screw-rod structure is excessive, and it does not also suit to use in the lower occasion of spatial altitude, easy like this be total to passive that bring.
Summary of the invention
The objective of the invention is to: a kind of novel lifting screw mechanism is provided, and it can improve the do not suit problem used in the lower occasion of spatial altitude of present lifting screw, thereby can bring the facility in the work.
The present invention realizes that technical method that above-mentioned purpose adopts is achieved in that a kind of novel lifting screw mechanism; It is by screw thread bush be provided with outside thread and negative thread hollow the weight lifting screw thread bush be provided with externally threaded weight lifting screw rod and constitute; Like this; Weight lifting screw sleeve and weight lifting screw rod two save the effect that can eject screw thread bush and play weight lifting; The height that this structure weight lifting screw rod and weight lifting screw sleeve descend behind the income screw thread bush inside is about 1/3rd of STRTHD jack, and therefore, the height of this structure is low and result of use is good.
Beneficial effect: the present invention is owing to adopt the type of drive of two joint threaded screw rods; So, the height behind this structure weight lifting screw rod and the weight lifting screw sleeve decline income screw thread bush inside is low, therefore; It is adapted at the lower occasion of spatial altitude and uses, thereby can bring the facility in the work.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Fig. 1 is a structural representation of the present invention.
Shown in the figure: 1, base; 2, screw thread bush; 3, weight lifting screw sleeve; 4, weight lifting screw rod; 5, big flange, 6, little flange; 7, little flange blind hole; 8, big flange blind hole.
The specific embodiment
It is made up of base 1, screw thread bush 2, weight lifting screw sleeve 3, weight lifting screw rod 4, big flange 5, little flange 6, little flange blind hole 7 and big flange blind hole 8; This structure screw thread bush 2 be provided with outside thread and negative thread hollow weight lifting screw thread bush 3 be provided with externally threaded weight lifting screw rod 4 and constitute; Like this; Weight lifting screw sleeve 3 can eject screw thread bush 2 with 4 liang of joints of weight lifting screw rod and play the effect of weight lifting, this structure weight lifting screw rod 4 and weight lifting screw sleeve 3 descend height behind income screw thread bushs 2 inside be about the STRTHD jack 1/3rd and highly low.
