Rotary low-impact self-separation pressing and releasing device

Abstract

The invention discloses a rotary low-impact self-separation pressing and releasing device. The upper end of a compressing rod compresses a separation spring onto an upper end cover through a compressing cap, the compressing rod sequentially penetrates through the upper end cover, an upper base, a limiting block and a rotating lock petal, the lower end of the compressing rod is fixedly connected with a separation nut, and the separation nut is fixedly connected with a lower base; a compressing nut is fixed onto the compressing rod and used for limiting rotating motion of the locking petal through a limiting block; an unlocking spring is installed between a stop dog of the rotating lock petal and a stop dog of the upper base, when the device is locked, the separation spring and the unlockingspring are in a pre-compressed state, and tapered teeth at the bottom of the rotating lock petal is occlusive in an over against mode. By means of the rotary low-impact self-separation pressing and releasing device, connected objects at the two ends can be connected and separated and do not move relatively during separation.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellites, in particular to a rotary low-impact self-separating compression release device. Background technique [0002] The pinch release device is often used for connection separation or pinch release between the satellite platform and the payload. Traditional compression and release devices include explosive bolts, separation push rods, pyrotechnic locks, etc. ("Spacecraft Structure and Mechanism", Chen Liemin, China Science and Technology Press, 2005), these traditional pyrotechnic compression and release devices have a large impact, With the development of satellite payload technology, high-precision payloads such as optical cameras are becoming more and more sensitive to impact loads. Traditional pyrotechnic compression and release devices have a greater impact and are prone to damage to payloads when they are unlocked. [0003] In addition, after the traditional compression and re...
