Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of good seal performance, the high nonabradable cylinder with rear capping plug of reliability.
Background technique
Sealing is to weigh an important indicator of cylinder standard, once whole gas circuit is leaked, the gas of leakage can flow to cylinder and be accumulated in pusher dynamic air cylinder generation misoperation together.At present, the cylinder on market generally adopts mounting O-shaped seal ring on piston, and dust-proof seal ring is installed in protecgulum to reach sealing effect, makes cylinder without internal and outernal leakage.Yet, in the cylinder using process of prior art, be all the connecting through hole that sees through bonnet, directly with screw rod or pin rod, pin car body fixture, there is no cushion, like this be firmly connected to cylinder operation time, easily there are deformation wearing and tearing, also easily cause dust accretion, sealability is had a greatly reduced quality, have a strong impact on the performance of cylinder, reduced the working life of cylinder.
Model utility content
The purpose of this utility model is to provide a kind of cylinder with rear capping plug, with solve existing cylinder exist deformation wearing and tearing and working life low technical problem.
For achieving the above object, the utility model provides a kind of cylinder with rear capping plug, comprise: protecgulum, bonnet, cylinder barrel, piston rod, piston, spool and protecgulum anti-dust seat, described protecgulum, cylinder barrel is connected successively with bonnet, described piston rod is arranged in described protecgulum, part is arranged in described cylinder barrel, described piston is arranged in described cylinder barrel and is connected with described piston rod, described spool is arranged in described piston and is connected with described piston, described protecgulum anti-dust seat is arranged on the inner and described piston rod socket of described protecgulum and is connected, also comprise a rear capping plug group, described rear capping plug group is arranged in the connecting through hole of described bonnet, described rear capping plug group further comprises: one first rear capping plug, described the first rear capping plug is a hollow cylinder, one end of described the first rear capping plug has one first outer rim boss, the other end of described the first rear capping plug has one first outer rim concave station, one second rear capping plug, described the second rear capping plug is a hollow cylinder, and one end of described the second rear capping plug has one second outer rim boss, and the other end of described the second rear capping plug has one second inner edge concave station, described the first rear capping plug is socketed and is connected in the connecting through hole of described bonnet with described the second rear capping plug.
The cylinder with rear capping plug described in the utility model preferred embodiment, also comprise two after capping plug O type circle, capping plug O type circle is connected with described the second rear capping plug with described the first rear capping plug respectively after described two.
The utility model improves existing cylinder, capping plug group after being provided with on bonnet, owing to adopting the rubber material of good springiness, reach flexible connecting structure stable, having shockproof cushioning effect is difficult for deforming, can absorb hardwired deformation wear-resisting property good, rear capping plug group socket sealing can not piled up dust, has extended the working life of cylinder.Therefore, compared with prior art, the utlity model has wear-resisting property good, stable performance, and the advantage of long service life.
