Missile rain-proof cover device

Abstract

The invention relates to a missile rain-proof cover device, particularly to an embedded type automatic locking rain-proof device. The embedded type automatic locking rain-proof device comprises a cover, a base, an outer covering leather, an elastic transformation plate, a torsional spring I, a torsional spring II, a clamping block, a rotation shaft and a locking pin, wherein the clamping block, the rotation shaft and the locking pin are connected with the torsional springs; the torsional spring I, the torsional spring II, the clamping block and the cover are fixed onto the base through the rotation shaft; the other end of the torsional spring I and one end of the torsional spring II are fixed onto the clamping block and the other end of the torsional spring II is fixed onto the cover to provide driving force for the rotation of the cover; the locking pin connects the clamping block with the rotation shaft and locks nuts. The missile rain-proof cover device can adjust the rigidity and the size of the sub torsional springs of the linkage torsional spring and compress the elastic transformation plate on the base through the initial preload force of the torsional springs according to the spatial distribution of the elastic bodies and the maximum working angle to meet the watertight requirements.

Description

technical field [0001] The invention relates to a missile rainproof port cover device, in particular to an embedded automatic locking rainproof device. Background technique [0002] In order to meet the requirements of aerodynamic performance and stealth technology for a certain missile, the separation socket of the missile must be buried inside the missile body, and the socket cover must be automatically locked after launch to achieve the rainproof effect. Because the aircraft-bomb separation socket of a certain missile is arranged under the launcher of the carrier aircraft, and the components in the missile body are arranged compactly, it is required that the self-locking rainproof port cover is small in size and the cover can rotate more than 150°. When the traditional single torsion spring or double torsion spring self-locking clamshell device meets the limit of the working angle and the strength of the spring material, it cannot be arranged due to the large volume occup...
