Abstract
A cylinder with a front cover special-shaped dustproof sealing ring comprises a front cover, a rear cover, a cylinder barrel, a piston rod, a piston, a valve core, a front cover press block and a front cover dustproof seat. The front cover, the cylinder barrel and the rear cover are connected in sequence, the piston rod penetrates through the front cover, a part of the piston rod is arranged in the cylinder barrel, the piston is arranged in the cylinder barrel and connected with the piston rod, the valve core is arranged in the piston and connected with the piston, the front cover dustproof seat is arranged in the front cover, the cylinder further comprises the front cover special-shaped dustproof sealing ring, and the front cover special-shaped dustproof sealing ring is arranged between the front cover dustproof seat and the front cover press block and is connected with the piston rod in a sleeved mode. The front cover special-shaped dustproof sealing ring is a round hollow piece body, and the thickness of a portion, close to the circle center, of the front cover special-shaped dustproof sealing ring is smaller than the thickness of the outer edge portion. The cylinder with the front cover special-shaped dustproof sealing ring has the advantages of being good in sealing performance, and stable in property.
Description
Technical field
The utility model relates to a kind of cylinder, relates in particular to a kind of cylinder with protecgulum abnormity dust-proof seal ring.
Background technique
Sealing is to weigh an important indicator of cylinder standard, in case whole gas circuit is leaked, the gas of leakage can flow to cylinder and be accumulated in together pusher dynamic air cylinder generation misoperation.At present, the cylinder on the market generally adopts mounting O-shaped seal ring on piston, and mounting plane type dust-proof seal ring makes cylinder reach sealing state when motion to reach sealing effect in the protecgulum briquetting.But, existing plane dust-proof seal ring, during use, in the piston rod movement process and the gap that inhomogeneous pressure produces between the piston rod easily produces the ventilation phenomenon, affects the performance of cylinder.
The model utility content
The purpose of this utility model is to provide a kind of cylinder with protecgulum abnormity dust-proof seal ring, exists between piston rod and the plane dust-proof seal ring and has the gap to solve existing cylinder, easily produces the technical problem of ventilation phenomenon.
For achieving the above object, the utility model provides a kind of cylinder with protecgulum abnormity dust-proof seal ring, comprise: protecgulum, bonnet, cylinder barrel, piston rod, piston, spool, protecgulum briquetting and protecgulum anti-dust seat, described protecgulum, cylinder barrel is connected with bonnet and is connected, described piston rod is arranged in described protecgulum, part is arranged in the described cylinder barrel, described piston is arranged in the described cylinder barrel and with described piston rod and is connected, described spool is arranged in the described piston and with described piston and is connected, described protecgulum anti-dust seat is arranged in the described protecgulum, cylinder also comprises protecgulum abnormity dust-proof seal ring, described protecgulum abnormity dust-proof seal ring is arranged between described protecgulum anti-dust seat and the protecgulum briquetting and with described piston rod socket and is connected, described protecgulum abnormity dust-proof seal ring is a circular hollow lamellar body, and the thickness of the close center of circle of described protecgulum abnormity dust-proof seal ring part is less than the thickness of peripheral edge portion.
The utility model improves existing cylinder, one protecgulum abnormity dust-proof seal ring is set between protecgulum anti-dust seat and protecgulum briquetting, when piston rod movement, protecgulum abnormity dust-proof seal ring is with piston rod movement direction generation deformation, in the whole course of action, protecgulum abnormity dust-proof seal ring is close to piston rod movement, and sealing effect is good, has avoided gas leakage.Therefore, compared with prior art, the cylinder that the utlity model has protecgulum abnormity dust-proof seal ring has advantages of good airproof performance, stable performance.
Description of drawings
Fig. 1 is the structural representation that the utlity model has the cylinder of protecgulum abnormity dust-proof seal ring;
Fig. 2 is the schematic diagram of the utility model protecgulum abnormity dust-proof seal ring;
Fig. 3 is the schematic diagram of the utility model protecgulum briquetting.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1, Fig. 2 and Fig. 3, a kind of cylinder with protecgulum abnormity dust-proof seal ring, comprise: protecgulum 1, bonnet 2, cylinder barrel 3, piston rod 4, piston 5, spool 6, protecgulum briquetting 9, protecgulum anti-dust seat 8 and protecgulum abnormity dust-proof seal ring 7, protecgulum 1, cylinder barrel 3 is connected with bonnet successively and is connected, piston rod 4 is arranged in protecgulum 1, part is arranged in the cylinder barrel 3, piston 5 is arranged in the cylinder barrel 3 and with piston rod 4 and is connected, spool 6 is arranged in the piston 5 and with piston 5 and is connected, protecgulum anti-dust seat 8 is arranged in the protecgulum 1, protecgulum abnormity dust-proof seal ring 7 is arranged between protecgulum anti-dust seat 8 and the protecgulum briquetting 9 and with piston rod 4 sockets and is connected, protecgulum abnormity dust-proof seal ring 7 is a circular hollow lamellar body, and the thickness of protecgulum abnormity dust-proof seal ring 7 close center of circle parts is less than the thickness of peripheral edge portion.
During the utility model work, when piston rod 4 motion, protecgulum abnormity dust-proof seal ring 7 is with piston rod 4 moving direction generation deformation, and in the whole course of action, protecgulum abnormity dust-proof seal ring 7 is close to piston rod 4 motions, and sealing effect is good, has avoided gas leakage.
The utility model improves existing cylinder, one protecgulum abnormity dust-proof seal ring is set between protecgulum anti-dust seat and protecgulum briquetting, and form the support ring of a bending in the extension of protecgulum briquetting, increased the area of contact with protecgulum, protecgulum abnormity dust-proof seal ring is placed in the support ring, when piston rod movement, protecgulum abnormity dust-proof seal ring is with piston rod movement direction generation deformation, in the whole course of action, protecgulum abnormity dust-proof seal ring is close to piston rod movement, sealing effect is good, has avoided gas leakage.Therefore, compared with prior art, the cylinder that the utlity model has protecgulum abnormity dust-proof seal ring has advantages of good airproof performance, stable performance.
Above disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should drop in the protection domain of the present utility model.
