Abstract

The invention discloses a pneumatic connection unlocking device, which belongs to the technical field of connection unlocking devices, through a cylinder barrel; a guide barrel, the outer side of one end of the guide barrel is detachably connected The seat is detachably connected to the outside of the end of the guide cylinder away from the cylinder barrel; the piston, the outside of the piston is matched with the inside of the guide cylinder, wherein the cylinder pushes the piston through the introduction of gas Movement, so that the pneumatic force drives the piston to move to the middle position of the guide cylinder, which achieves the technical effect of simple structure, improving the reliability of unlocking under heavy load conditions, and achieving the technical effect of reusable device.

Description

technical field [0001] The invention relates to the technical field of connection unlocking devices, in particular to a pneumatic connection unlocking device. Background technique [0002] In the field of aerospace, there are a large number of connection and unlocking structures between the vehicle and the payload, such as separation between stages, separation of vehicle and satellite, and deployment of satellite sailboards. At present, pyrotechnic devices are mainly used for connection and unlocking. [0003] The pyrotechnic device is mainly composed of an ignition element, a charge and a functional mechanism. Its principle is to use the energy generated by the explosion or combustion of the charge to drive the functional mechanism to complete a specific function. The pyrotechnic devices used for connection and separation mainly include explosive bolts, separation nuts, pin pullers and other devices, which have the advantages of high reliability, large energy storage, fast...
