Launching system of small parachute

Abstract

The invention discloses a launching system of a small parachute, and relates to the field of safety devices, in particular to a small-parachute safe landing device. The launching system comprises a base, an outer cylinder, an inner cylinder and a launcher. The inner cylinder is arranged inside the outer cylinder, and the inner cylinder and the outer cylinder arranged in a concentric circle mode; the inner cylinder and the outer cylinder are both arranged on the base; an igniter is arranged at the portion, located inside the inner cylinder, of the center of the base; the launcher is arranged inside the inner cylinder and located right above the igniter; the igniter is used for igniting the launcher; at least three empennage grooves are formed in the periphery of the inner cylinder; guiding empennages matched with the empennage grooves are arranged on the periphery of the igniter, and the number of the guiding empennages is the same as that of the empennage grooves; the launcher is used for pulling out the parachute. According to the launching system, a launched body is subjected to guiding positioning through the launching cylinders, the parachute in a parachute bin is bulked through an air guide hole, and it is prevented that the parachute is snarled and cannot be normally unfolded.

Description

technical field [0001] The invention relates to the field of safety equipment, in particular to small parachute safety landing equipment. Background technique [0002] The launching system of the small-sized parachute in the prior art generally adopts spring power to start, and the response time of the parachute started by the spring power is long, the response is slow, and the spring is in a compressed state for a long time, and the metal will fatigue and deform, resulting in the reduction of the elastic force of the spring. Spring-powered parachutes are much less safe to use. There will be situations where the parachute responds slowly, the parachute cannot be ejected, etc., and eventually the parachute cannot be opened in time to cause a crash.

AI Technical Summary

Problems solved by technology

[0002] The launching system of the small-sized parachute in the prior art generally adopts spring power to start, and the response time of the parachute started by spring power is long and slow, and the spring is in a compressed state for a long time, and the metal will fatigue and deform, resulting in the reduction of the elastic force of the spring. Spring-powered parachutes are much less safe to use

There will be situations where the parachute responds slowly, the parachute cannot be ejected, etc., and eventually the parachute cannot be opened in time to cause a crash

[0003] The launcher of the launch system of the small-sized parachute of the prior art shoots directly from the inner tube, but the launcher of the prior art is poor in stability, and the direction deviation is prone to occur after being shot out of the inner tube, and the umbrella body with the parachute will deviate from the direction , and ultimately lead to the failure of the umbrella to open in time, resulting in a crash

If precision machining is used to ensure the emission direction of the emitter, its production cost will also increase greatly, which is not conducive to industrial production

[0004] The launch system of the small parachute in the prior art generally adopts mechanical control plus spring power, and its response time is long. If an accident occurs at an ultra-low altitude and a parachute is required to be used, there is a serious safety hazard, and the long response time prevents it from being opened in time. parachute, causing the crash
