Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of parachute, especially relates to a parachute with prevent air turning over function. BACKGROUND

[0002] The parachute is an aeronautical tool for making people or things safely fall from the sky to the ground by using air resistance principle and relying on the inflatable deployable aerodynamic decelerator moving relative to the air, which is mainly made of flexible fabric, and is widely used in the field of aerospace, and the main purposes include emergency lifesaving (such as rescuing pilots when the plane crashes), stabilizing effect (such as keeping the attitude of the ejection seat stable), deceleration effect (such as brake deceleration when the plane lands) and the like.

[0003] At present, the existing parachute cannot be opened when the parachute surface is rotated and pinched in when being unfolded due to the influence of air flow in the air, that is, the parachute surface is turned over in the air, which undoubtedly has a great impact on the person falling, and is easy to cause safety accidents, and therefore the use effect needs to be improved.

[0004] To solve the above problems, the parachute with prevent air turning over function is provided. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a parachute with prevent air turning over function, which solves the problems in the background art.

[0006] To solve the above technical problems, the utility model is realized by the following technical scheme:

[0007] The utility model is a parachute with prevent air turning over function, which comprises a parachute body and a rope body at the lower end of the parachute body, the lower ends of adjacent rope bodies are fixed by a bundle rope, a wind filling pipe for guiding air flow is arranged at the lower end of the parachute body, a wind guide pipe is arranged at the upper end of the wind filling pipe, an outer branch pipe is arranged at the upper end of the wind guide pipe, an air bag for assisting parachute opening is arranged at the upper end of the outer branch pipe, and an adapter rope connected with the wind filling pipe is arranged on one side of the upper rope body; the outer branch pipe and the wind guide pipe are combined structures, and when the outer branch pipe is separated, the air flow overflowing from the outer branch pipe impacts the inner surface of the parachute body to assist parachute opening and resist the influence of external air flow.

[0008] Further, a limiting ring is arranged at the lower end of the wind filling pipe, a temple part of the limiting ring is provided with an inner ring sleeve, and the outer side of the inner ring sleeve is provided with an elastic jack for pushing the limiting ring outward.

[0009] Further, a positioning hole is arranged in the inner ring sleeve, and the inner ring sleeve is bent to gather adjacent elastic jacks for storage.

[0010] Furthermore, both the air duct and the outer branch pipe are provided with protruding bosses on their outer sides, and a pull rope is provided at the upper end of the bosses on the outer side of the air duct.

[0011] Furthermore, the outer side of the outer branch pipe has a limiting hole for a pull rope to pass through inside the boss, and the pull rope has a protruding elastic protrusion on the outside to abut against the inner wall of the groove extending outward inside the limiting hole to form a limit.

[0012] Furthermore, the upper end of the pull rope is provided with a limiting ball that abuts against the upper port of the limiting hole to form a limit.

[0013] Furthermore, the airbag, outer branch pipe, and air duct are all flexible structures that facilitate storage and folding for use.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, by adding an air-filling pipe, allows the limiting ring to be opened by an elastic push rod during parachute deployment, enabling airflow to enter the interior. This causes the airbag to bulge outwards and push the parachute open, preventing it from collapsing and achieving the effect of assisting parachute deployment. This ensures the smooth operation of parachute deployment, effectively improves deployment efficiency, reduces the probability of accidents, and protects the personal safety of the lander.

[0016] This invention connects adjacent protrusions with a pull rope. When the airbag cannot open the umbrella, the outer branch tube is pushed out and separated as the airflow increases. At this time, the incoming airflow impacts the inside of the umbrella, assisting it to open outward. This can prevent the umbrella from failing to open when the inside is deflated, and provides a more stable performance in the face of airflow.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
