BUFFER DEVICE FOR CAPTURING HIGH-TEMPERATURE FLYING-OFF SAMPLE IN SUPERGRAVITY ENVIRONMENT

摘要

A buffer device for capturing a high-temperature flying-off sample in a supergravity environment. An outer flange at the bottom of a lower support body (9) is fixed on a test device base; an upper support body (3) is fixed at the top of the lower support body; a buffer body (5) is arranged in a through hole groove of the lower support body and a vertical channel of the upper support body; a poke rod (2) is assembled in an upper special-shaped groove (3-3) formed in the upper support body; a locking shaft (4) is hinged in a hinging hole (3-4) of the upper special-shaped groove; the poke rod passes through the upper special-shaped groove of the upper support body and a lower special-shaped groove (5-2) of the buffer body extend into a vertical through hole of the buffer body; a buffer structure (10) is assembled on a lower-layer partition plate (11); the upper support body (3) is provided with four grooves (3-2), each groove is provided with a guide groove (3-1) and provided with a blocking piece (6), and blocking piece guide bars (6-2) are embedded in the guide grooves and move along the guide grooves; and after the poke rod penetrates a limiting groove (6-1) of the blocking piece upwards, a journal of the poke rod is in contact connection with an outer side face of the blocking piece. The present buffer device can be assembled simply and used conveniently, can quickly capture and isolate a high-temperature flying-off sample, and can effectively solve the problem of the high-temperature flying-off sample damaging a test cabin under supergravity.
