Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of lifting screw, and this jack structure is simple, easy to use.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of lifting screw is provided, comprise: screw sheel, screw rod and base, described screw sheel is set in described base, one end of described screw rod is stretched in described screw sheel, on the other end of described screw rod, be arranged with top cover, the negative thread on the outside thread on described screw rod and described screw sheel matches.
In a preferred embodiment of the present invention, on the other end of described screw rod, be installed with rocking bar.
In a preferred embodiment of the present invention, between described screw-casing jacket casing and described base, there is pin to be fastenedly connected.
In a preferred embodiment of the present invention, between the described other end of described screw rod and described top cover, there is rivet to be fastenedly connected.
The invention has the beneficial effects as follows: this lifting means can promote various article, height and the stroke of lifting are controlled, easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of lifting screw of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, base, 2, screw sheel, 3, screw rod, 4, pin, 5, rocking bar, 6, rivet, 7, top cover.
The specific embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of lifting screw, comprise screw sheel 2, screw rod 3 and base 1, described screw sheel 2 is set in described base 1, one end of described screw rod 3 is stretched in described screw sheel 2, on the other end of described screw rod 3, be arranged with top cover 7, the negative thread on outside thread and described screw sheel 2 on described screw rod 3 matches.
Preferably, on the other end of described screw rod 3, be installed with rocking bar 5.
Preferably, between described screw-casing jacket casing 2 and described base 1, there is pin 4 to be fastenedly connected.
Preferably, between the described other end of described screw rod 3 and described top cover 7, there is rivet 6 to be fastenedly connected.
When use, rotating rocker 5 makes screw rod 3 in the interior rotation of screw sheel 2, and while screw rod 3 is in the interior lifting of screw sheel 2, thus the object up-down that drive is pushed up.
The beneficial effect of lifting screw of the present invention is:
Lifting screw of the present invention is simple in structure, easy to use.
