Abstract
The utility model discloses an prevent changeing cylinder, including cylinder and front cover and the hou gai of setting at the cylinder both ends, be equipped with the piston in the cylinder, install the piston rod on the piston, first fixed plate and second fixed plate are installed respectively at both ends about the cylinder, are provided with between first fixed plate and the second fixed plate and prevent the pivot, and the second is fixed a position the board on the piston right side, prevents that the right-hand member of pivot passes the piston and is connected with the piston and rotate with the restriction piston. In this way, the utility model discloses prevent changeing the cylinder can prevent changeing that mechanical structure is realized to the axle through increasing one in the cylinder body, simple structure, low in manufacturing cost, and application range is wide.
Description
Technical Field
The utility model relates to a cylinder field especially relates to an prevent changeing cylinder.
Background
The cylinder is not fixed because the piston and the piston rod are in a circular design, and only can rely on self friction, and if an external rotating force or a lateral force borne by the cylinder connecting piece is greater than the friction of the piston and the piston rod, the piston rod of the cylinder can rotate. The rotating piston rod can accelerate the friction between the dustproof ring and the piston rod and between the piston ring and the cylinder wall of the cylinder, and the service life of the cylinder is influenced. Meanwhile, the connecting piece of the air cylinder is likely to be loosened by the rotation of the air cylinder shaft, and potential safety hazards exist in the use process.
Disclosure of Invention
The utility model discloses the main technical problem who solves provides an anti-rotation cylinder can realize that mechanical structure prevents changeing through increasing one in the cylinder body and prevent changeing the axle, simple structure, low in manufacturing cost, application range is wide.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides an anti-rotation air cylinder, includes the cylinder and sets up protecgulum and the hou gai at the cylinder both ends, be equipped with the piston in the cylinder, install the piston rod on the piston, first fixed plate and second fixed plate are installed respectively at both ends about the cylinder, be provided with between first fixed plate and the second fixed plate and prevent the pivot, the second is fixed a position the board in the piston right side, the right-hand member of preventing the pivot passes the piston and is connected in order to restrict the piston rotation with the piston.
In a preferred embodiment of the present invention, the piston is provided with an anti-rotation hole for engaging with the anti-rotation shaft.
In a preferred embodiment of the present invention, the left end of the first fixing plate contacts the front cover, and the right end of the second fixing plate contacts the rear cover.
In a preferred embodiment of the present invention, the piston rod is provided with a buffer sleeve, and the front cover is provided with a buffer slot matched with the buffer sleeve.
the utility model has the advantages that: the utility model discloses prevent changeing the cylinder, can prevent changeing that mechanical structure's commentaries on classics is realized to the axle through increase one in the cylinder body, simple structure, low in manufacturing cost, application range is wide.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
FIG. 1 is a schematic structural view of a preferred embodiment of an anti-rotation cylinder of the present invention;
The parts in the drawings are numbered as follows: 1. the cylinder, 2, protecgulum, 3, back lid, 4, piston, 5, piston rod, 6, first fixed plate, 7, second fixed plate, 8, prevent changeing the axle, 9, prevent changeing the hole, 10, cushion collar, 11, wear the dashpot.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, an anti-rotation cylinder includes a cylinder barrel 1, and a front cover 2 and a rear cover 3 disposed at two ends of the cylinder barrel 1, a piston 4 is disposed in the cylinder barrel 1, a piston rod 5 is mounted on the piston 4, a first fixing plate 6 and a second fixing plate 7 are respectively mounted at the left end and the right end of the cylinder barrel 1, an anti-rotation shaft 8 is disposed between the first fixing plate 6 and the second fixing plate 7, the second fixing plate 7 is disposed at the right side of the piston 4, and the right end of the anti-rotation shaft 8 penetrates through the piston 4 and is connected with the piston 4 to limit the rotation of the piston 4.
In addition, the piston 4 is provided with an anti-rotation hole 9 matched with the anti-rotation shaft 8.
In addition, the left end of the first fixing plate 6 contacts the front cover 2, and the right end of the second fixing plate 7 contacts the rear cover 3.
In addition, the piston rod 5 is provided with a buffer sleeve 10, and the front cover 2 is provided with a buffer groove 11 matched with the buffer sleeve 10.
The utility model discloses prevent changeing the cylinder and only need prevent pivot 8 and two fixed plates at inside increase one of ordinary cylinder, increase one on piston 4 and prevent changeing hole 9, all the other parts all use original ordinary cylinder can. The material is rarely increased, the material is extremely common, and the processing is also extremely convenient. Because the cylinder is modified on the basis of the common cylinder, the external dimension and the installation mode are not different from those of the common cylinder, and the cylinder can be used in any common cylinder environment and can be well applied even under severe conditions such as high temperature or low temperature.
Be different from prior art, the utility model discloses prevent changeing the cylinder can prevent changeing that mechanical structure is realized to the axle through increasing one in the cylinder body, simple structure, low in manufacturing cost, application range is wide.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
