Missile tail cover convenient to dismount and mount and capable of being prevented from falling

Abstract

The invention relates to a missile tail cover convenient to dismount and mount and capable of being prevented from falling in the technical field of missiles. The missile tail cover comprises a tail spraying pipe, a sealing mechanism is arranged inside the tail spraying pipe, an anti-falling mechanism is fixedly connected to the middle of the left side surface of the sealing mechanism, the anti-falling mechanism is located inside the tail spraying pipe, a push-pull mechanism is fixedly connected to the right side surface of the sealing mechanism, the push-and-pull mechanism is located outsidethe tail spraying pipe, and two symmetrical limiting mechanisms are fixedly connected to the right side surface of the tail spraying pipe. According to the missile tail cover convenient to disassembleand assemble and capable of being effectively prevented from falling, a sealing cover plate is arranged, therefore, under the action of a sealing ring, the tail spraying pipe can be effectively sealed, and the situation that external dust enters the interior of the tail spraying pipe, so that the operation of a missile engine is influenced is fully avoided; and a limiting block is arranged, therefore, under the combined action of lifting rods, springs, limiting rods and a conical block, the missile tail cover can be conveniently clamped in the interior of the tail spraying pipe, and the missile tail cover can be effectively prevented from falling from the interior of the tail spraying pipe.

Description

technical field [0001] The invention relates to the technical field of missiles, in particular to a missile tail cover which is easy to assemble and disassemble and prevents falling off. Background technique [0002] A missile is a weapon that is propelled by its own power plant, guided and controlled by a guidance system to guide its warhead to destroy the target. [0003] In order to prevent external dust from entering the interior of the missile engine from the missile engine tail nozzle, it is necessary to seal the missile engine tail nozzle. Existing seals for the missile engine tail nozzle are generally blocked by rubber tail caps or metal tail caps. The tail cover is easy to fall off and dust can enter, and the metal tail cover needs to be screwed to the tail nozzle with screws. This connection method requires the use of a screwdriver when disassembling the tail cover of the missile engine tail nozzle. It is cumbersome to operate and waste the working time of the sta...
