Plug mounting structure capable of realizing pull rope adjustment and separation protection

Abstract

The invention belongs to the technical field of aerospace crafts, and discloses a plug mounting structure capable of achieving pull rope adjustment and separation protection. The plug mounting structure comprises a pull rope fixing frame, a screw rod and a locking nut; the top of the pull rope fixing frame is provided with a cavity; one end of the screw rod is provided with a sliding block; the sliding block is slidably arranged in the cavity; a round hole is formed in one side wall of the cavity of the pull rope fixing frame; the screw rod penetrates through the round hole and then is in threaded connection with the locking nut; single-row tooth grooves are formed in the two opposite side walls of the cavity of the pull rope fixing frame; the single-row tooth grooves are communicated with the cavity; and tooth grooves of the single-row tooth grooves are arranged at equal intervals. The plug mounting structure further comprises a limiting block; single-row teeth matched with the single-row tooth grooves are arranged on the limiting block; and single-row limiting tooth grooves are symmetrically formed in the two sides of the sliding block; a connecting structure is arranged on the sliding block; and a pull rope is connected with the sliding block through the connecting structure. According to the plug mounting structure capable of realizing pull rope adjustment and separation protection of the invention, after a separation plug and a socket are in butt-joint, a pull rope adjusting structure can be used for measuring and controlling the slack amount of the pull rope on the separation plug.

Description

technical field

[0001] The invention relates to the technical field of aerospace vehicles, in particular to a plug installation structure that can realize pull cord adjustment and separation protection. Background technique

[0002] Space rockets need to perform high-altitude separation functions during flight to separate and throw away the useless parts that have completed the scheduled work from the rocket body, thereby improving the rocket's quality characteristics, increasing range and flight control capabilities. Near the separation surface inside the rocket, a special detachable plug (hereinafter referred to as the separation plug) is usually installed. Once the pull rope on the separation plug is pulled, the unlocking between the plug and the socket will be realized immediately, which is to ensure the normal operation of the rocket. One of the important prerequisites for separation. The drawstring of the separation plug needs to reserve slack during installation to p...
