A quick release cap device

Abstract

The invention discloses a device for disassembling a covering cap quickly. The device comprises a base, a hole cover, a limiting clamp, limiting pins and a switch key, wherein the switch key is inserted into a threaded hole in the hole cover; the hole cover is rotated in the direction of starting ends of two 90-degree elliptic arc grooves; the two limiting pins are moved in the axis directions of the limiting pins under the action of two springs until the two limiting pins are abutted against the starting ends of the two 90-degree elliptic arc grooves of the hole cover, and a locking state is realized; the switch key is inserted into the threaded hole in the hole cover, the hole cover is rotated in the direction of finish ends of the two 90-degree elliptic arc grooves, the two limiting pins are moved in the axis direction of the limiting pins under the action of the two 90-degree elliptic arc grooves until the two limiting pins are completely squeezed out of the two 90-degree elliptic arc grooves, and an unlocking state is realized; the two limiting pins are abutted against a cylindrical surface of the hole cover, then the hole cover 2 can be taken down, and power-on operation of effective loads in a capsule can be realized. With the adoption of the device, the covering cap can be disassembled and assembled quickly in short time.

Description

technical field [0001] The invention belongs to the technical field of missile testing, and in particular relates to a quick-release cover device, which is suitable for quick disassembly and installation of a window cover for missile rocket testing. Background technique [0002] The quick-release cover mechanism is set according to the special requirements of some equipment in the missile (rocket), and is tested, adjusted and inspected before the missile (rocket) is launched. The mechanism has a simple structure, can quickly install and disassemble the mouth cover, and is easy to operate. [0003] The payload carried by a certain rocket needs to be powered on before launch, and the rocket cabin is designed with an opening for power-on operation, which is sealed with a cover. Remove the cover before power-on operation, and install the cover after power-on operation. After installation, the cabin must meet the sealing requirements. Before the launch of the rocket, it is nece...

AI Technical Summary

Problems solved by technology

The quick-release cover is installed and fixed with three fasteners. Disassembly and installation require more operations and take a relatively long time, which affects the accuracy of payload detection data and cannot guarantee structural integrity and operational reliability during flight.
