Abstract
The invention discloses a rotary air cylinder stroke adjusting screw which comprises a lead screw, a first nut, a second nut, a connecting rod, a spring buffer piece and a buffer cap. The first nut and the second nut are arranged at the two ends of the lead screw respectively, the connecting rod penetrates through the lead screw, the connecting rod is connected with the spring buffer piece, and the spring buffer piece is connected with the buffer cap. In this way, the rotary air cylinder stroke adjusting screw is good in buffer reset performance, good in pressure-resistant property and excellent in durability.
Description
Technical field
The present invention relates to screw field, particularly relate to a kind of rotary cylinder and adjust journey screw.
Background technique
Screw utilizes the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, the by easy stages instrument of fastening implements parts.Screw is the general saying of fastening piece, daily pet phrase.Screw is industrial necessity indispensable in daily life: the minimum screw used as photographic camera, glasses, clock and watch, electronics etc.; The general screw of TV, electric product, musical instrument, furniture etc.; Large-scale screw, nut is then used as engineering, building, bridge; Traffic tool, aircraft, electric car, automobile etc. then sized by screw using.Screw industrially bears vital task, as long as the earth also exists industry, then the function of screw is forever important.Screw is the joint invention over the past thousands of years in people's productive life, and according to application, it is the first invention of the mankind.
But current rotary cylinder adjusts the buffering reseting performance of journey screw poor, and withstand voltage properties is poor, and endurance quality has much room for improvement.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of rotary cylinder and adjusts journey screw, and buffering reseting performance is good, and good pressure-resistant performance, endurance quality is good.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of rotary cylinder to adjust journey screw, comprise: screw rod body, the first nut, the second nut, connecting rod, spring buffer part and buffer cap, the two ends of described screw rod body are respectively arranged with the first described nut and the second described nut, run through in described screw rod body and have described connecting rod, described connecting rod is connected with described spring buffer part, described spring buffer part is connected with described buffer cap.
In a preferred embodiment of the present invention, the length of described spring buffer part is identical with the length of connecting rod.
In a preferred embodiment of the present invention, the length of described spring buffer part is greater than the length of connecting rod.
In a preferred embodiment of the present invention, the thickness of described buffer cap is 1 ~ 2cm.
The invention has the beneficial effects as follows: it is good that the present invention cushions reseting performance, good pressure-resistant performance, and endurance quality is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation that rotary cylinder of the present invention adjusts the preferred embodiment of journey screw one;
In accompanying drawing, the mark of each parts is as follows: 1, screw rod body, the 2, first nut, the 3, second nut, and 4, connecting rod, 5, spring buffer part, 6, buffer cap.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained 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 rotary cylinder adjusts journey screw, comprise: screw rod body 1, first nut 2, second nut 3, connecting rod 4, spring buffer part 5 and buffer cap 6, the two ends of described screw rod body 1 are respectively arranged with the first described nut 2 and the second described nut 3, run through in described screw rod body 1 and have described connecting rod 4, described connecting rod 4 is connected with described spring buffer part 5, described spring buffer part 5 is connected with described buffer cap 6.
In the present invention, the length of described spring buffer part 5 is identical with the length of connecting rod 4.
In the present invention, the length of described spring buffer part 5 is greater than the length of connecting rod 4.
In the present invention, the thickness of described buffer cap 6 is 1 ~ 2cm.
The beneficial effect of rotary cylinder tune journey screw of the present invention is: it is good that the present invention cushions reseting performance, good pressure-resistant performance, and endurance quality is good.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
