Abstract

The invention provides a locking piece, a connector and a low-temperature rocket system, which are suitable for penetrating through a first piece and a second piece and have a locking state of fixing the first piece and the second piece and a separating state of unlocking the first piece and the second piece; the system further comprise a shaft sleeve structure with a built-in accommodating cavity having the end part abutted against the first piece, and a shaft core structure penetrating through the first piece and the second piece and comprising a locking sleeve, a limiting adjusting piece and an abutting piece; the limiting adjusting piece and the abutting piece are arranged on the locking sleeve, the abutting piece is arranged in a protruding mode in the circumferential direction of the locking sleeve and abuts against the second piece, and the limiting adjusting piece comprises a second elastic piece; and the limiting adjusting piece is suitable for having the locking state of being clamped with the accommodating cavity and the separation state of being separated from the accommodating cavity under the adjustment of the second elastic piece.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a locking piece, a connector and a low-temperature rocket system. Background technique [0002] Cryogenic rocket refers to the carrier rocket whose engine uses cryogenic propellant. As the cryogenic propellant of liquid rocket engine, such as liquid hydrogen, liquid oxygen or methane, it has the characteristics of low temperature and high performance. Cryogenic rockets need to be filled with propellant and provide the necessary gas before launch, and the arrow-ground connector is the key equipment to ensure that the propellant and gas are delivered to the cryogenic rocket. [0003] All rocket-ground connectors need to fall off reliably before the rocket is launched. In the prior art, it is difficult for the locking parts on the connectors to achieve effective and controllable locking and falling off. Contents of the invention [0004] Therefore, the technical problem to be ...
