The umbrella frame adopts an umbrella structure, and the umbrella structure is relatively complicated, and it is easy to fail under the condition of high pressure.

The object of this application research is the civilian life-saving parachute used for common people to escape when high-rise fire or for high-altitude operators such as air-conditioning installers and glass cleaners.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a low-altitude life-saving parachute, which has a simple mechanical structure and is not prone to errors, and can quickly open the umbrella surface, which is suitable for use in low-altitude operations.

The solution of the present invention to solve the technical problem is: a civilian lifesaving parachute, including an umbrella body and a strap for connecting with the human body, the umbrella body includes an umbrella rib, an umbrella surface, and a parachute rope, and the umbrella rib is made of at least 3 metal The rod is formed after the middle part is fixed, and the metal rod is stretched in a cavity connected with the strap after the middle part is bent. There is an ejection device in the cavity, which can eject the umbrella body out of the cavity. After the umbrella body ejects from the cavity, the umbrella body The bottom is still connected with the cavity, and the switch for controlling the ejection device is arranged on the cavity.

As an improvement, the ejection device is a spring located in the cavity.

As an improvement, the bottom of the umbrella body is provided with a ferrule, the top of the cavity has a partition, and the top of the ferrule has an enlarged part. The blocking keeps the ferrule always in the cavity; the ejection device is located between the enlarged part of the ferrule and the bottom of the cavity.

As an improvement, the switch includes a pin and a buckle connected to the bottom of the ferrule, and the pin is inserted into the buckle to realize tensioning and fixing of the ejection device.

As an improvement, the bottom of the cavity has a through hole through which the buckle passes, and the pin is located outside the bottom of the cavity.

As an improvement, the cavity is provided with a gravitational acceleration sensor, a stepping motor, and a battery. After the gravitational acceleration sensor senses the acceleration, the stepping motor can be started, and the stepping motor pulls the latch to make the umbrella eject from the cavity.

The mechanical structure of the present invention is simple and stable, the failure rate of the mechanical structure is low, and the umbrella surface can be quickly opened after the metal rod bounces off, and it can play a huge role in the event of an accidental fall (such as cleaning the glass from a high altitude) or jumping from a building to survive in a fire, and is effective. Great prospects for development.

detailed description

Example 1

As shown in FIGS. 1-3 , a civilian lifesaving parachute includes an umbrella body 1 and a strap 2 for connecting with a human body. The ribs 11 are formed by at least three metal rods fixed in the middle, and the metal rods are bent in the middle and tensioned in a cavity 3 connected with the strap 2 . The cavity 3 is a hollow columnar body. An ejection device 4 is arranged in the cavity 3 , and the ejection device 4 is a spring located in the cavity 3 . The ejection device 4 can eject the umbrella body 1 from the cavity 3, and the bottom of the umbrella body 1 is still connected with the cavity 3 after the umbrella body 1 ejects from the cavity 3, and the cavity 3 is provided with a switch 5 for controlling the ejection device 4. The material of the metal rod is memory metal, and the metal rod can recover quickly after the umbrella body 1 pops out of the cavity 3 .

The bottom of the umbrella body 1 is provided with a ferrule 14, the top of the cavity 3 has a barrier part 31, and the top of the ferrule 14 has an enlarged part 15. After the umbrella body 1 pops out of the cavity 3, the enlarged part 15 of the ferrule 14 is covered by the cavity. The blocking portion 31 of the body 3 blocks the ferrule 14 to always be located in the cavity 3 ; the ejection device 4 is located between the enlarged portion 15 of the ferrule 14 and the bottom of the cavity 3 .

The switch 5 includes a pin 51 and a buckle 52 connected to the bottom of the ferrule 14 , the pin 51 is inserted into the buckle 52 to realize the tensioning and fixing of the ejection device 4 . The bottom of the cavity 3 has a through hole 32 through which the buckle 52 passes, and the latch 51 is located outside the bottom of the cavity 3 .

The cavity 3 is provided with a gravitational acceleration sensor 61, a stepping motor 62, and a battery 63. After the gravitational acceleration sensor 61 senses the acceleration, the stepping motor 62 can be started, and the stepping motor 62 pulls the latch 51 to make the umbrella body 1 pop out of the cavity. 3.
