Abstract
The present invention relates to a kind of two-way pneumatic support bar.Including piston cylinder, the piston cylinder is respectively arranged at two ends with upper piston rod and lower piston rod, the upper end of the lower end of the upper piston rod and lower piston rod is respectively penetrated in piston cylinder, fairlead is provided with the upper end of the piston cylinder, lower fairlead is provided with the lower end of the piston cylinder, the upper fairlead is socketed on upper piston rod, the lower fairlead is socketed on lower piston rod, the lower end of the upper piston rod is connected with upper piston, the upper end of the lower piston rod is connected with lower piston, and the outer wall of the upper piston and lower piston is provided with O-ring seal I.Present configuration is simple, by arranging gas spring at piston cylinder two ends, becomes two gas springs that can independently stretch or compress, enables to two ends uniform force, meet different stroke range.
Description
Technical field
The present invention relates to a kind of support bar, more particularly to a kind of two-way pneumatic support bar.
Background technology
Pneumatic power support lever is also known as gas spring, it is a kind of industry accessories that can play the effects such as support, buffering, braking, principle is to be filled with inert gas or gas mixture in closed piston cylinder, make several times or tens times of air pressure superatmospheric in piston cylinder, the motion of piston rod is realized using the difference in areas of piston and piston rod to produce pressure differential, have with respect to common spring mobile slow, be easily controlled, for a long time by being capable of restorable advantage after compression or stretching.But the support bar of unidirectional stretching, extension its mechanical rigid in Long travel does not reach use requirement, and two ends stress is not uniform enough, therefore has limitation in some fields.
Content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of simple structure, disclosure satisfy that different stroke range, a kind of two-way pneumatic support bar of two ends uniform force is made.
For this technical solution adopted in the present invention it is：
Including piston cylinder, the piston cylinder is respectively arranged at two ends with upper piston rod and lower piston rod, the upper end of the lower end of the upper piston rod and lower piston rod is respectively penetrated in piston cylinder, fairlead is provided with the upper end of the piston cylinder, lower fairlead is provided with the lower end of the piston cylinder, the upper fairlead is socketed on upper piston rod, the lower fairlead is socketed on lower piston rod, the lower end of the upper piston rod is connected with upper piston, the upper end of the lower piston rod is connected with lower piston, and the outer wall of the upper piston and lower piston is provided with O-ring seal I.
Further, the inwall of the upper and lower ends of the upper fairlead is equipped with sealing ring I, the sealing ring I and is enclosed within upper piston rod, and the sealing ring I is lip-type packing.
Further, the inwall of the upper and lower ends of the lower fairlead is equipped with sealing ring II, the sealing ring II and is enclosed within lower piston rod, and the sealing ring II is lip-type packing.
Further, O-ring seal II is equipped with the outer wall of the upper fairlead and lower fairlead.
Further, the upper end of the upper fairlead is provided with dust ring and is enclosed within upper piston rod, and the upper dust ring is located in the upper end of piston cylinder.
Further, the lower end of the lower fairlead is provided with lower dust ring and is enclosed within lower piston rod, and the lower dust ring is located in the lower end of piston cylinder.
It is an advantage of the invention that：
Present configuration is simple, by arranging gas spring at piston cylinder two ends, becomes two gas springs that can independently stretch or compress, enables to two ends uniform force, meet different stroke range.
