Problems solved by technology

In this form, the structure is simple and the cost of parts is low, but it is not suitable for use under the conditions of small separation load and multi-point simultaneous release actions. It is necessary to accurately determine the direction of separation and release, the trajectory of motion, and the driving force and acceleration during separation. Control, and the fatigue resistance is not good, and the release timing cannot be selected according to the control needs

Abstract

The application provides a coupling release device, which belongs to the technical field of mechanical coupling. The device includes a shell structure, a controlled driving piston penetrating the shell, and a connecting guide, one end of which is used to connect with the device to be locked, and the other end is provided with a groove; two release rockers arranged side by side, two One end of the release rocker arm is hingedly arranged in the groove of the connecting guide through the same rotating shaft, and when the two release rocker arms rotate around the rotating shaft to overlap each other, the two release rocker arms The other ends jointly form a through hole that is adapted to the pin shaft at the end of the first cylinder of the driving piston, and in the overlapping state, the other ends of the two release rocker arms can follow the The first cylinder protrudes into the through hole of the housing structure, and is restricted from rotating around the rotating shaft by the wall of the through hole. The device can realize the quick release separation function and can reinstall the locking joint in the original installation position.

Description

technical field [0001] The present application belongs to the technical field of mechanical coupling, and in particular relates to a coupling release device. Background technique [0002] The coupling release device is used to fix the locking piece and release the locking piece when necessary. It is often used in pilot ejection lifesaving control systems and water floating recorders. The butterfly recorder with floating function can be separated from the body automatically, and this separation requires a coupling release device to complete. [0003] The existing connection release device mainly adopts three forms: a simple mechanical lock form; a blasting separation form; a fixed force bolt connection form. In the form of a simple mechanical lock, the components of the device are complicated, the release speed is slow, and the reliability is poor, and it is not suitable for multi-point simultaneous linkage and use under the condition of greater connection strength. At prese...
