Abstract
The utility model relates to a two -way pneumatic bracing piece. Including the piston cylinder, the piston cylinder both ends are equipped with shang rod and lower piston pole respectively, shang rod's the lower extreme and the upper end of lower piston pole penetrate in the piston cylinder respectively, be equipped with the uide bushing in the upper end of piston cylinder, be equipped with down the uide bushing in the lower extreme of piston cylinder, it cup joints on shang rod to go up the uide bushing, the uide bushing cup joints on the lower piston pole down, shang rod's lower extreme is connected with the upper piston, the upper end of lower piston pole is connected with the lower piston, be equipped with O type sealing washer I on the outer wall of upper piston and lower piston. The utility model discloses simple structure through setting up the air spring at piston cylinder both ends, becomes two air springs that can independently extend or compress, can make the both ends atress even, satisfies different stroke scopes.
Description
Technical field
The utility model relates to a kind of strut, particularly relates to a kind of two-way pneumatic strut.
Background technique
Pneumatic power support lever is also known as air spring, it is a kind of industry accessories that can play the effects such as support, buffering, braking, principle is filled with inert gas or gas mixture in airtight piston cylinder, make air pressure in piston cylinder higher than several times, barometric pressure or tens times, utilize the difference in areas of piston and piston rod to produce pressure difference to realize the motion of piston rod, have relative to common spring and mobile slowly easily to control, to be compressed for a long time or can restorable advantage after stretching.But the strut of unidirectional stretching, extension its mechanical rigid when Long travel does not reach usage requirement, and two ends are stressed even not, therefore have narrow limitation in some field.
Model utility content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, can meet different stroke range, make a kind of two-way pneumatic strut of two ends uniform force.
The technological scheme that the utility model adopts for this reason is:
Comprise piston cylinder, described piston cylinder two ends are respectively equipped with upper piston rod and lower piston rod, the lower end of described upper piston rod and the upper end of lower piston rod penetrate in piston cylinder respectively, guide sleeve is provided with in the upper end of described piston cylinder, lower guide sleeve is provided with in the lower end of described piston cylinder, described upper guide sleeve is socketed on upper piston rod, described lower guide sleeve is socketed on lower piston rod, the lower end of described upper piston rod is connected with upper piston, the upper end of described lower piston rod is connected with lower piston, and the outer wall of described upper piston and lower piston is provided with O RunddichtringO I.
Further, the inwall at the two ends up and down of described upper guide sleeve is equipped with seal ring I, and described seal ring I is enclosed within upper piston rod, and described seal ring I is lip-type packing.
Further, the inwall at the two ends up and down of described lower guide sleeve is equipped with seal ring II, and described seal ring II is enclosed within lower piston rod, and described seal ring II is lip-type packing.
Further, the outer wall of described upper guide sleeve and lower guide sleeve is equipped with O RunddichtringO II.
Further, the upper end of described upper guide sleeve is provided with dust ring and is enclosed within upper piston rod, and described upper dust ring is positioned at the upper end of piston cylinder.
