The air bag mounting ring 7 located at the upper end is located at the periphery of the air release hole 62.
The connecting string 4 passes through the airbag mounting ring 7 and the airbag 71.
A baffle 51 is arranged below the sealing piece 5, the area of the baffle 51 is smaller than that of the sealing piece 5, the baffle 51 is fixedly connected to the pressure relief piece 6, and the outer edge of the sealing piece 5 is pressed on the pressure relief piece 6 by the baffle 51. The gasket 5 is the ox muscle piece, separation blade 51 is hard material, can be metal or hard plastic material. The stopper piece 51 is fixedly attached to the pressure relief sheet 6 by a screw 52.
The lifting platform comprises a lifting platform 3, the lifting platform further comprises a hanging and buckling device 8, the hanging and buckling device 8 is arranged at the top of the support 2, the hanging and buckling device 8 comprises a pin shaft 84 and a rotating rod 82 which is connected to the pin shaft 84 and can rotate around the pin shaft 84, the top of the rotating rod 82 is further connected with a handle 81 extending forwards, one side of the rotating rod 82 is provided with a butt 83, the other side of the rotating rod 82 is butted with an elastic sheet 85, the lifting platform 3 comprises a butt 34, the top of the lifting platform 3 is provided with a mounting block 33, the butt 34 is connected to the rear side of the mounting block 33, the butt 83 is located on a lifting path of the butt 34, the butt 34 upwards extrudes the butt 83 and compresses the elastic sheet 85 in the lifting process of the lifting platform 3, the butt 34 rises to exceed the butt 83, and the butt 34 descends to be limited by.
The working principle of the invention is shown in fig. 6, two spaces need to be reserved on the floor slab 9 of each layer of households for the installation and use of the vertical descending mechanism, warning devices can be arranged at the peripheries of the two spaces, people cannot occupy the two places at ordinary times, the two places need to be separated, and the floor slab 9 is preferably the floor slab 9 on a balcony, because the balconies of all the upper and lower households are opposite up and down. In the two spaces provided with the warning device, one floor hole 91 needs to be formed in the floor 9 for the lifting platform 3 to pass through (the support 2 and the protection pipe 1 can also pass through according to the actual situation), and the other floor hole can be used for placing a cushion (as shown in the left side of fig. 6), so that the horizontal part 32 can play a role in buffering when descending to the bottom. Normally, the horizontal portion 32 of each floor hole 91 may extend slightly beyond the surface of the floor 9. When fire and other dangerous situations need to escape, an escaper directly walks onto the horizontal part 32, at the moment, the lifting platform 3 is limited by the locking action of the abutting head 83 and cannot descend, the escaper pulls the handle 81 forwards by hand, the handle 81 rotates along the pin shaft 84, the rotating rod 82 overcomes the elastic force of the elastic sheet 85 at the moment, so that the abutting head 83 moves backwards (namely, the abutting head 83 moves backwards to the right in fig. 5), at the moment, the locking action of the abutting head 83 on the abutting part 34 is eliminated, the weight of the escaper is far greater than the mass of the counterweight block 72, the lifting platform 3 descends, the lifting platform 3 pulls out the connecting rope 4 and drives the counterweight block 72 to ascend, the counterweight block 72 ascends and extrudes the air bag 71, so that the air in the air bag 71 is compressed rapidly, the freely drooping sealing sheet 5 is pushed upwards by the compressed air to block the air release hole 62, and the sealing sheet area of the sealing sheet 51 is smaller than that the sealing sheet, the stop piece 51 serves as a support to prevent the sealing sheet 5 from sagging too much and deforming. When the sealing sheet 5 blocks the air release hole 62, the lifting speed of the counter weight 72 gradually becomes slow under the action of atmospheric pressure in the air bag 71, namely, the lifting platform 3 slowly descends, when the lifting platform 3 descends to the next floor 9, the escaper escapes from the family to the next floor, and then the escaper can transit to the next floor by using the same method, and so on.
When the escaper switches the direct-falling mechanism, the lifting platform 3 of the originally used direct-falling mechanism can automatically rise to return to the original position, specifically: after the escaper leaves the horizontal part 32, the balancing weight 72 descends by means of self weight, and drives the lifting platform 3 to ascend, and in the descending process, the volume of the air bag 71 becomes large, the external air is supplemented into the air bag 71 through the air leakage hole 62, namely the sealing sheet 5 is pushed downwards by the external air, so that the air leakage hole 62 is no longer blocked by the sealing sheet 5, and the sealing sheet 5 cannot be excessively pressed down by the top due to the existence of the blocking sheet 51. When the lifting platform 3 is lifted, the abutting portion 34 overcomes the elastic force of the elastic sheet 85 to abut against the pressing head 83, so that the pressing head 83 retreats, after the abutting portion 34 passes over the pressing head 83 upwards, the pressing head 83 is reset forwards under the elastic force of the elastic sheet 85, at this time, the descending of the abutting portion 34 is limited by the pressing head 83 located at the lower part, and the next escaper must manually dial the handle 81 when using the escape.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
