Abstract

The present invention provides a locking piece, a connector and a low-temperature rocket system, which are suitable for passing through the first piece and the second piece, and have a locking state for fixing the first piece and the second piece and unlocking the separated state of the first part and the second part, it also includes: a shaft sleeve structure with a built-in accommodation cavity, and the end of the accommodation cavity abuts against the first part; a shaft core structure through which Through the first piece and the second piece, it includes a locking sleeve, a limit adjustment member and an abutment set on the locking sleeve, and the abutting piece protrudes along the circumferential direction of the locking sleeve set and abut against the second piece, the limit adjustment member includes a second elastic member, and the limit adjustment member is adapted to be engaged with the accommodating cavity under the adjustment of the second elastic member The locked state of engagement and the disengaged state of disengaging from the accommodating cavity.

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 ...
