Piston rod described in cover seal, described cylinder barrel is connected with described end cap seal, and described pull bar, rod nut are connected to described end cap
On.
A kind of above-mentioned cylinder vacuum seal structure, it also includes fairlead, and described fairlead loads close in described end cap
Seal and support described piston rod.
A kind of above-mentioned cylinder vacuum seal structure, described piston rod O-ring has three.
A kind of above-mentioned cylinder vacuum seal structure, described dust-proof composite rim is provided with two.
A kind of above-mentioned cylinder vacuum seal structure, it also includes cylinder barrel O-ring, and described cylinder barrel O-ring loads described end cap,
Described end cap is connected with the sealing of described cylinder barrel.
A kind of above-mentioned cylinder vacuum seal structure, it also includes end cap O-ring, and described end cap O-ring loads described end cap
Sealing installed surface.
A kind of above-mentioned cylinder vacuum seal structure, described end cap is provided with leak hunting aperture, and described detection small opening is located at described anti-
Between dirt composite rim.
A kind of above-mentioned cylinder vacuum seal structure, described end cap is provided with oil filler point, and described oil filler point is located at described piston
Between bar O-ring and dust-proof composite rim.
Due to employing technique scheme, it efficiently solves to lack at present and can be used for vaccum working condition this utility model
The problem of middle cylinder, the perfect species of cylinder, have dependable performance, dimensionally stable, easy to use the features such as.Total reaches
To good sealing effectiveness, particularly piston rod Chu You five road sealing, when piston rod works in vacuum environment, in cylinder
Gas will not enter in vacuum environment with piston rod, is particularly suitable in the operating mode need vacuum.

Specific embodiment
As depicted in figs. 1 and 2, this utility model cylinder vacuum seal structure includes piston rod 1, piston rod O-ring 2, end
Lid 3, dust-proof composite rim 4, fairlead 5, cylinder barrel O-ring 6, cylinder barrel 7, end cap O-ring 8, pull bar 9 and rod nut 10.Piston rod O
Type circle 2, dust-proof composite rim 4, fairlead 5 load end cap 3 sealing piston bar 1.Cylinder barrel O-ring 6 is loaded end cap 3 and is connected with cylinder barrel 7
Place, end cap 3 and cylinder barrel 7 is sealed and is connected it is ensured that its sealing, prevent cylinder barrel 7 and end cap 3, the gas leakage of bonnet junction.End cap O
Type circle 8 loads end cap 3 leading flank, and this face and installed surface are sealed by O-ring it is ensured that its sealing, prevent gas from being pacified by end cap
Dress face enters vacuum environment it is ensured that stable work in work.Please refer to Fig. 5, end cap 3 pass through pull bar 9, rod nut 10 with after
Cover locking, cylinder barrel 7 is also by pull bar 9 and rod nut 10 and end cap 3 and bonnet locking.Fairlead 5 loads end cap 3, and position exists
After dust-proof composite rim 4, act the effect supporting piston rod 1 it is ensured that piston rod 1 operates steadily.
As shown in figure 4, this utility model total reaches good sealing effectiveness, particularly piston rod 1 Chu You five road
Sealing, is made up of three piston rod O-ring 2 and two dust-proof composite rims 4.When piston rod 1 works in vacuum environment, cylinder
Interior gas will not enter in vacuum environment it is ensured that its sealing with piston rod 1, makes cylinder become vacuum cylinder.
As shown in figure 3, end cap 3 is provided with a leak hunting aperture 12 and two oil filler points 11.Leak hunting aperture 12 is close positioned at first
Between envelope and second sealing（I.e. between two dust-proof composite rims 4）, first sealing whether gas leakage can be detected at any time.Note
Oilhole 11 is located between second sealing and three seals（Between piston rod O-ring 2 and dust-proof composite rim 4）, by this hole
Vacuum grease can be injected, make cylinder keep stable performance.Oil filler point 11 can also be used for hunting leak, logical after first sealing gas leakage
Cross oil filler point 11 and can detect second sealing whether gas leakage.This structure can detect that first sealing is sealed with second at any time
Whether gas leakage, to change sealing member in time, makes cylinder performance be in stable, reliable working condition all the time.
