AI Technical Summary
When adjusting the length of existing compensators, one end usually extends outward while the other end remains in the same position, resulting in uneven extension of the compensator.
A sealing compensator was designed. Through the cooperation of the moving component and the sealing component, the handle drives the moving rod to rotate, and the slider and the fixed block move to achieve uniform extension of the bellows. The sealing is achieved by the expansion of the air bladder and the blocking of the baffle.
It achieves uniform extension at both ends when the bellows length is adjusted, and the airbag seal avoids friction damage, thus improving the service life of the compensator.
