Embodiment Construction

[0024] The following content describes in detail the specific embodiment of the present invention in conjunction with the accompanying drawings:

[0025] like figure 1 As shown, the base 5 of the hook lock buffer device is fixed on the pulley through the bolt hole 6, the pin shaft 3 connects the anti-lock 4 and the base 5, and the torsion spring 2 acts on the base 5 and the anti-lock 4 with a certain pre-tightening force , the two ends of the elastic rope 1 are fixed on the launch car, when the hook lock buffer device hits the elastic rope with the pulley at high speed, the anti-lock button 4 is subjected to the force of the elastic rope opposite to the direction of motion, and the anti-lock button 4 is wound around the pin The shaft 3 rotates counterclockwise, so that the elastic rope 1 enters the inner space of the hook lock smoothly, and because the torsion spring 2 has a large pre-tightening force, the anti-lock button 4 will return to its original position under th...

Abstract

The invention provides a hook lock buffering device for buffering and absorbing the shock of a pulley of an ejection system on an unmanned aerial vehicle. The hook lock buffering device comprises a torsion spring, a pin shaft, a counter lock catch and a base, wherein the pin shaft is connected with the counter lock catch and the base, and the torsion spring on the pin shaft acts on the base and the counter lock catch by certain pre-tightening force. The hook lock buffering device has the beneficial effects that the unmanned aerial vehicle and the pulley are in high-speed movement after being launched from the ejection system, the hook lock buffering device can meet the buffering and speed-reduction requirements of the pulley after the unmanned aerial vehicle is released, and thus the pulley is prevented from rigidly colliding with an ejection device.

Description

[0001] Technical field: [0002] The invention belongs to the field of ejection systems, in particular to a hook lock buffer device for the ejection system, and is especially suitable for the buffering of the fast and highly reliable ejection system of unmanned aerial vehicles. [0003] Background technique: [0004] The UAV ejection system is the product of the development of advanced UAV technology mobility. It consists of a launcher, energy system, tackle, buffer device, etc. It can eject various types of advanced drones, and has become an important trend in the development of new weapons and equipment. The UAV ejection system has the following technical advantages: (1) Small size and powerful function. It does not need a large-area airstrip, the launch process is short, and the take-off speed is high; (2) It has strong maneuverability and survivability. The entire UAV can be installed on a transport carrier (car, warship, locomotive, etc.), so that it has good mane...
