DETAILED DESCRIPTION

[0037] The embodiment of the present invention provides a fall prevention and escape device, such as Figure 1-10 As shown, it includes a telescopic mechanism and a trigger mechanism. The trigger mechanism is installed on the outer wall 1 of the building. The telescopic mechanism is installed on the window 2 or the lower edge of the balcony. Under normal circumstances, the telescopic mechanism is in a telescopic state. When the trigger mechanism is triggered, the telescopic mechanism is driven to extend to form a cantilever platform to catch the person who has fallen, providing precious time for rescue personnel to further rescue the person who has fallen from the building. At the same time, since the telescopic mechanism has a smaller relative height than the air cushion on the ground, it is more conducive to reducing the impact on the person who has fallen from the building. A plurality of telescopic mechanisms can be provided, and they can be arranged in a horizontal and vertical staggered manner to perform multi-level caching and rescue of the person who has fallen from the building.

[0038] Specifically, Figure 1 , 2As shown in Figure 3, the telescopic mechanism includes a group of telescopic frames 3 and a telescopic net bag 4. The telescopic net bag 4 is arranged between a group of telescopic frames 3. The telescopic frame 3 includes a support rod 5 and a slider 6 sliding on the support rod 5, and a scissor connecting rod group 7. The support rod 5 is fixedly set on the outer wall 1 of the building. The lower end of the innermost connecting rod of the scissor connecting rod group 7 is hinged on the support rod 5, and the upper end is hinged on the slider 6.

[0039] like Figure 1 As shown in Figure 3, an inclined rope 8 is also provided on the telescopic mechanism, the upper end of which is fixed on the outer wall 1 of the building, and the lower end is connected to the outermost end of the scissor link group 7, so that the telescopic mechanism cantilever effect is better.

[0040] Furthermore, the trigger mechanism includes a sensing component and a driving component. The sensing component is electrically connected to the driving component. The driving component can drive the slider 6 to move up and down on the support rod 5, thereby extending the telescopic mechanism.

[0041] In this embodiment, Figure 4 , 5 As shown, the sensing component includes a cantilever rod 9, a slide 10, and a slider 11. The slide 10 is fixedly arranged above the building outer wall 1 at the upper end of the telescopic mechanism. One end of the cantilever rod 9 is arranged on the slider 11. The slider 11 is arranged in the slide 10. The sliding of the slider 11 is restricted by a restriction rope 12. The function of the restriction rope 12 is to prevent false sensing of objects thrown from high altitude or birds landing.

[0042] In this embodiment, Figure 1 , 9 As shown, the driving assembly includes an inflating device, and the inflating device includes an air bag 13 and a sealing cylinder 14. The sealing cylinder 14 contains sodium azide 15, and the sodium azide 15 is pre-buried with a pyrotechnic device 16;

[0043] like Fig. 9 As shown, the slide block 11 is provided with a ball tube sensor, including a steel ball 17 and a tube 18. Magnets 19 are provided on both sides of the tube 18. A connecting electric sheet 20 is provided in the chamber at the lower end of the tube 18. The connecting electric sheet 20 is connected in series with a battery 21 and a pyrotechnic device 16.

[0044] In normal state, the steel ball 17 is located at the upper end of the pipe 18 under the action of the magnet 19. When the cantilever rod 9 is pressed downward, the limiting rope 12 is torn off, driving the slider 11 to move downward rapidly and then stop rapidly. Under the action of inertia, the steel ball 17 falls into the cavity below the pipe 18, and the connecting electric sheet 20 is connected to open the circuit. The electrical signal is transmitted to the pyrotechnic device 16, generating high temperature, causing the sodium azide 15 to explode, and rapidly expanding the airbag 13, thereby expanding the telescopic mechanism.

[0045] like Figure 6 , 7 As shown in Figure 8, a locking mechanism is also provided on the support rod 5, and the locking mechanism includes a locking pin 22, a spring 23, and a locking plate 24. The locking plate 24 is arranged on the side of the support rod 5, and a locking hole 25 is provided on the locking plate 24. The locking pin 22 is slidably set at the lower end of the slider 6, and the spring 23 is connected between the locking pin 22 and the slider 6. The locking pin 22 has an arc toward the lower outer end.

[0046] like Figure 4 , 5 As shown, the inner end of the cantilever rod 9 is hinged on the slider 11, the outer end of the hinge shaft is connected to the gear 26, a limit column 27 is set between the teeth of the gear 26, and a rack 28 is set under the slide 10. When the slider 11 moves downward in the slide 10, the gear 26 is meshed with the rack 28, driving the cantilever rod 9 to break through the obstruction of the limit column 27 and rotate downward.

[0047] like Figure 3 As shown, a telescopic fence is also provided on the telescopic frame 3 , and the telescopic fence includes a fence rod 29 and a fence rope 30 . The fence rod 29 is provided on the hinge point of the connected connecting rod, and the fence rope 30 is connected to the fence rod 29 .

[0048] Preferably, the telescopic mechanism corresponds to a plurality of sensing components, and the sensing components are dispersedly arranged on the building outer wall 1 above the telescopic mechanism.

[0049] Others can also be found in Fig. 9 An alarm mechanism, such as a flashing alarm light and a whistle speaker, is added to the circuit shown. When the circuit is connected, the flashing alarm light and the whistle speaker are activated.

[0050] like Figure 1 As shown, the upper end of the airbag 13 is connected to the outer wall through the airbag bracket 31, and the lower end of the airbag 13 is connected to a group of sliders 6 of the telescopic mechanism through a connecting plate;

[0051] Working principle: When the anti-fall escape device is used, the person falling from the building first touches the cantilever rod 9 of the sensing component during the falling process. Under the action of the gravity of the person falling from the building, the limiting rope 12 is torn off, and the cantilever rod 9 moves downward with the slider 11 in the slide 10. When it falls to the bottom of the slide 10, the gear 26 on the hinge shaft of the cantilever rod 9 meshes with the rack 28, driving the cantilever rod 9 to flip downward to reduce the harm to the personnel. At the same time, the slider 11 suddenly stops at the bottom of the slide 10 during the rapid falling process, and the steel ball in the slider 11 is in the inertia. Under the action of the adsorption force of the magnet 19, it breaks away from the pipe 18 and falls into the lower chamber, contacts the connecting electric sheet 20, connects the circuit, and transmits the electrical signal to the pyrotechnic device 16 in the sealing cylinder 14, which instantly generates a high temperature of 300 degrees, causing the sodium azide 15 to explode, generating a large amount of nitrogen (2NaN3=2Na+3N2), inflating the airbag 13, and the airbag 13 pushes the connecting rod to drive the slider 6 to move downward in the support rod 5, thereby unfolding the telescopic mechanism, which has a telescopic net bag 4 to hold the falling person, thereby increasing the rescue time for the rescue personnel.
