Problems solved by technology

[0002] In the field of ejection of small UAVs weighing more than 50 kg, there is no electromagnetic catapult suitable for such UAVs in China. According to reports, only the United States and Israel have similar UAV boosters. Domestically produced rubber band catapults can only eject Boost drones below 50 kg, and drones weighing more than 50 kg can only be boosted by solid explosive rockets, which is very dangerous and very difficult to carry and transport

Embodiment Construction

[0004] The trigger buckle of the catapult with a double joint and spring structure, the main structure includes a fixed box, an exciting shaft, a magnetic ring and a semicircular extrusion structure with a handle; in a fixed box, an exciting shaft is installed. Put two magnetic rings on the shaft, and the magnetic ring at the back is an extrusion magnetic ring, which is in contact with the semicircular extrusion structure with a handle. When the semicircular extrusion structure with a handle is moved more than one third; squeeze The pressure magnetic ring will push the excitation magnetic ring to slide quickly on the excitation shaft to achieve the purpose of excitation.

Abstract

The invention provides a catapult stimulation buckle with permanent magnet rings as a contact structure. The main structure of the catapult stimulation buckle comprises a fixed box, a stimulation shaft, the magnet rings, a semi-circular extrusion structure with a handle, and other components. The stimulation shaft is arranged in the fixed box, the stimulation shaft is sleeved with the two magnet rings, and the latter magnet ring is an extrusion magnet ring and makes contact with the semi-circular extrusion structure with the handle. When the semi-circular extrusion structure with the handle moves over one third, the extrusion magnet ring can push the stimulation magnet ring to quickly slide on the stimulation shaft, and therefore the purpose of stimulation can be achieved.

Description

Technical field [0001] The invention relates to an activation button of an ejector with a permanent magnet ring as a contact structure, in particular to an activation button with both a mechanical structure and a permanent magnet ejection structure. It belongs to the technical field of unmanned aerial vehicle catapults. Background technique [0002] In the field of ejection of small UAVs weighing more than 50 kg, there is no electromagnetic catapult suitable for such UAVs in China. According to reports, only the United States and Israel have similar UAV boosters. Domestically produced rubber band catapults can only eject UAVs under 50 kg can be boosted, and UAVs weighing more than 50 kg can only be boosted by solid explosive rockets, which is very dangerous and very difficult to carry and transport. Contents of the invention [0003] The trigger buckle of the catapult with a double joint and spring structure, the main structure includes a fixed box, an exciting shaft, a m...
