Abstract

This utility model relates to the field of gas spring sealing performance testing technology, and discloses a gas spring sealing performance testing device, including a sealing test chamber. A hydraulic push rod is mounted on the bottom of the sealing test chamber via a frame. A sealing ring is fitted onto the surface of the output end of the hydraulic push rod, and the top of the sealing ring is installed on the bottom of the sealing test chamber. The output end of the hydraulic push rod extends into the interior of the sealing test chamber and is movably connected to a pressure plate. A lifting plate is fitted onto the surface of the output end of the hydraulic push rod, and a cross-shaped push plate is fixedly connected to the surface of the output end of the hydraulic push rod. In this utility model, through the cooperation of the sealing test chamber, hydraulic push rod, sealing ring, pressure plate, lifting plate, waterproof reduction motor, elliptical plate, and sliding sleeve, the elliptical plate rotates, and the elliptical plate repeatedly compresses the gas spring through the sliding sleeve, achieving the effect of dynamic sealing performance testing of the gas spring.
