[0002] With the rapid development of science and technology in my country, the requirements for the use environment and functional performance of the seeker displacement device are becoming higher and higher under the new situation, especially for the seeker displacement device used in the aerospace environment. The seeker displacement device needs to be miniaturized, lightweight, high-strength, and have good air tightness, testability, stability, reliability, etc. Therefore, there is an objective demand: under the premise of the positioning and locking of the seeker mechanism in the aerospace environment, it has the characteristics of fast unlocking, rapid launch, small impact, large load, rapid feedback signal to the collector after it is in place, and good testability in a limited space. Although there are seeker displacement devices that are gradually used in different aircraft, most of them have single functions, complex structures, insufficient reaction speed, large impact, and low testability and reliability. For example, a barrel-launched rotary cruise missile and its working method disclosed in CN116499307A pushes out the propulsion device through a spring and unlocks the mechanical arm through a motor. The unlocking and pushing out of the seeker use two different sets of drive systems respectively, which makes the unlocking and pushing out structure of the seeker complicated, and the use of a spring to push out the seeker requires the reliability of the spring.

[0029] The high-pressure accumulator 1 can exhaust gas at a constant pressure of a certain ratio within a certain period of time, so that the unlocking and lifting process is smooth and smooth.

[0030] The initial locking mechanism 2 is connected to the high-pressure accumulator 1 through the first gas pipeline 8. After the high-pressure accumulator 1 releases the gas source, the initial locking mechanism 2 is completely unlocked and the gas source enters the lifting cylinder 3 to ensure the safety of the guide head mechanism 6 during the pushing process.

[0031] The initial locking mechanism 2 is designed with an air source detection interface, which can detect the pressure in the lifting cylinder 3.

[0032] The lifting cylinder 3 is connected to the initial locking mechanism 2 through the second air pipeline 9. A vibration-damping ring is provided on the internal lever of the lifting cylinder 3, which can buffer the guide head mechanism 6 and reduce the impact.

[0033] The lifting cylinder 3 is hinged to the guide head mechanism 6 through a lever screw 14, a vibration-damping pad 13, and a pin shaft 12. The vibration-damping pad 13 can provide reverse buffering to the guide head mechanism 6 to reduce reverse impact.

[0034] The rolling guide pair 5 is symmetrically distributed with the lifting cylinder 3 as the center, and can bear 20000N in one direction.
