Problems solved by technology
[0002] At present, the rescue device for people who have fallen from a height is an inflatable air mattress. Its advantages are light weight, easy to carry, and low requirements on the flatness of the ground. The disadvantage is that it takes a certain time to inflate. Falling from a high height, the air bed will basically fail. The reason is that the falling person will compress the compressed gas in the entire air bed at the moment of contact with the air bed. The surface of the air bed will have a huge impact on the falling person, and the person will be more than 9 times the acceleration of gravity beyond the limits of human tolerance
Therefore, the use is limited

Embodiment Construction
[0009] The invention relates to an elastic anti-falling net, and its structural shape and composition relationship are embodiments of the invention.
[0010] If the rescue site is uneven, first place three universal wheel brackets 5, insert the bottom bracket 4 into the corresponding hole, the bottom bracket 4 can swing universally, and the vertical frame 3 on both sides and the rear vertical frame 8 have a certain rigidity frame, then insert it into the corresponding holes of the bottom bracket 4, and then hang the mesh cloth on one side of the top of the two vertical poles 7, and the two vertical poles (7) are inserted into the vertical frame on both sides (3) and the rear vertical frame (8) There is a corresponding hole with a certain rigid frame, one side is hung on the top of the U-shaped rocker arm 1, the two ends of the rotating shaft of the U-shaped rocker arm 1 are inserted into the corresponding holes of the vertical frames 3 on both sides, and two oil damping gas spr...

The invention relates to an elastic anti-falling net for saving the lives of people falling from a high position. According to the principle that screen cloth is tensioned, the inside is high and theoutside is low, outside tensioning is formed, and a rocker can swing inwards, a person falling from a high position obtains gradually-increased negative acceleration after falling into the net, meanwhile, under the oblique mounting effect of the screen cloth, the falling person falls, changes the falling direction and rolls at the same time, the impulse in the direction perpendicular to the groundis well defused, energy is converted, the falling person is safely rescued, and the motion trail of the falling person on the screen cloth is V-shaped. Considering that the falling speed of the humanbody in the air is generally smaller than 90 m / s, the inner side screen cloth of the elastic anti-falling net is supported to be 7 m high, and the falling person will bear 8-9 gravitational accelerations. Therefore, no matter how high the falling person falls, the falling person falls into the elastic anti-falling net and has no large injuries.

The surface of the air bed will have a huge impact on the falling person, and the person will be more than 9 times the acceleration of gravity beyond the limits of human tolerance. Therefore, the use is limited. Contents of the invention [0003] In view of the above problems, the elastic anti-falling net of the present invention uses the principle of tensioning ...
