Abstract
The utility model provides an improved air cylinder with small size and long service life. The improved air cylinder comprises an air cylinder body and an air inlet which is formed in the air cylinder body, wherein a piston is arranged in the air cylinder body, a spring is arranged below the piston, a cavity of the air cylinder body is divided into a front cavity and a rear cavity by the piston, and the outer circumferential surface of the piston is provided with a Y-shaped sealing ring for sealing. According to the improved air cylinder, the piston is provided with the Y-shaped sealing ring and an anti-abrasion ring, so that not only is a sealing effect good, but also the anti-abrasion ring has a certain guide effect, and the swinging of the air cylinder caused by the factors can be efficiently reduced.
Description
Technical field
The utility model relates to a kind of cylinder, especially a kind of modified model cylinder that is applicable to the 3rd rail pantagraph current collector.
Background technique
Existing cylinder volume is larger, and working life is short, and poor-performing is not suitable for using in the place of narrow space.
The model utility content
The purpose of this utility model is to provide that a kind of volume is little, the modified model cylinder of long service life.
Realize the modified model cylinder of the utility model purpose, comprise cylinder body, be positioned at the suction port of cylinder body top, be provided with piston in described cylinder body, the piston below is provided with spring, described piston is separated into ante-chamber and back cavity with the cavity of cylinder body, and the outer peripheral surface of described piston is provided with the y-shaped ring for sealing.
On the outer peripheral surface of described piston, the below that is positioned at y-shaped ring also is provided with for the wear ring that leads.
The utility model beneficial effect is as follows: modified model cylinder of the present utility model, y-shaped ring and wear ring have been installed on piston, not only good sealing effect, and wear ring also has certain leading role, can effectively reduce the swing of cylinder because produced by some factor.
Description of drawings
Fig. 1 is the structural representation of modified model cylinder of the present utility model.
Embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, modified model cylinder of the present utility model, comprise cylinder body 1, be positioned at the suction port 2 of cylinder body 1 top, be provided with piston 5 in described cylinder body 1, piston 5 belows are provided with spring 6, and described piston 5 is separated into ante-chamber 3 and back cavity 4 with the cavity of cylinder body 1, and the outer peripheral surface of described piston 5 is provided with the y-shaped ring 7 for sealing.
On the outer peripheral surface of described piston 5, the below that is positioned at y-shaped ring 7 also is provided with for the wear ring 8 that leads.
The working principle of modified model cylinder of the present utility model is as follows: modified model cylinder of the present utility model, and gas enters from suction port 2, and piston 5 is subject to the promotion of aerodynamic force, moves toward back cavity 4, by y-shaped ring 7 sealings, prevents from collaborating between ante-chamber 3, back cavity 4; After gas disconnected, piston 5 was subject to the spring force of spring 6 and resets.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; do not breaking away under the spiritual prerequisite of the utility model design; various distortion and improvement that the common engineers and technicians in related domain make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
