[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0026] like Figure 1-5 As shown, the utility model proposes a stepped evacuation platform, including an evacuation platform body 22 and a mounting plate 1 installed on one end of the evacuation platform body 22. The mounting plate 1 is provided with a pair of bolt holes 16 for mounting the mounting plate 1 on the evacuation platform body 22. The function of the bolt holes 16 is to facilitate the disassembly and assembly of the steps on the mounting plate 1. A pair of handrails 17 for the evacuees to manually hold are provided on the upper surface of the mounting plate 1. The function of the handrails 17 is to provide stable support for the evacuees when passing through the steps of the evacuation platform, to help the evacuees maintain balance, and to reduce the risk of falling due to slippery, fatigue, etc. It also includes: a step mechanism for evacuating personnel, which is rotatably connected to the mounting plate 1 and located at one end of the evacuation platform body 22; a rebound mechanism installed on the evacuation platform body 22 and the step mechanism for automatically popping out the step mechanism after mutual cooperation; and a button mechanism provided on the mounting plate 1 for limiting the automatic pop-up of the step mechanism.

[0027] Furthermore, the ladder mechanism includes a pair of support rods 4, a pair of rotating grooves 2 are provided on the mounting plate 1, and the inside of the rotating grooves 2 are rotatably connected with rotating blocks 3, the tops of the support rods 4 are fixedly connected with the corresponding rotating blocks 3, and the bottom ends of the support rods 4 are movably sleeved with telescopic plug rods 7, and each pair of telescopic plug rods 7 and the support rods 4 are provided with step plates 5 for evacuation personnel to step on, and the upper surfaces of the step plates 5 and the supporting bottom plate 8 are provided with a plurality of linearly arranged anti-slip strips 6, and the material of the anti-slip strips 6 is rubber, and its function is to effectively increase the friction force on the surface of the step plates 5, reduce the risk of slipping caused by wet, slippery, greasy and other reasons when people go up and down the step platform, and improve the safety of the evacuated personnel. One of the step plates 5 is provided with a through groove 15 for the telescopic hook rod 12 to movably penetrate and then for the hook 13 to pass through, and the bottom ends of the pair of telescopic plug rods 7 are fixedly connected with the supporting bottom plate 8 for supporting the ground.

[0028] The rebound mechanism includes a pair of connecting plates 18, which are fixedly connected to the telescopic plug rod 7. The telescopic plug rod 7 is fixedly connected with a first spring 19, and the function of the first spring 19 is to make the step mechanism rotate in the direction of the support rod 23. One end of the first spring 19 is fixedly connected with a push plate 20, and the lower surface of the mounting plate 1 is fixedly connected with a support rod 23 for the push plate 20 to resist. The support rod 4 is provided with a second spring 21 that cooperates with the first spring 19. The function of the second spring 21 is to make the support base plate 8 at the bottom of the step mechanism automatically resist the ground.

[0029] Furthermore, the button mechanism includes a button 11, and a telescopic slot 9 is provided on the mounting plate 1 for the button 11 to be telescopically extended upward and downward, and a third spring 10 is provided inside the telescopic slot 9. The function of the third spring 10 is to make the button 11 drive the hook 13 at the bottom end of the telescopic hook rod 12 to automatically snap into the hook slot 14, thereby limiting the rotation of the ladder mechanism in the direction outside the supporting rod 23. The bottom of the button 11 is provided with a telescopic hook rod 12 that movably penetrates the mounting plate 1, and the bottom end of the telescopic hook rod 12 is fixedly connected with a hook 13, and a hook slot 14 for the hook 13 to snap into is provided on the lower surface of one of the step plates 5.

[0030] In this embodiment, when a stepped evacuation platform is required, Figure 4 and Figure 5 As shown, the button 11 is pressed downward, and the bottom end of the button 11 drives the telescopic hook rod 12 to slide along the telescopic groove 9, and the bottom end of the telescopic hook rod 12 drives the hook 13 to escape from the hook groove 14 at the bottom of one of the step plates 5. At this time, a pair of telescopic plug rods 7 are subjected to the elastic thrust of the first spring 19 on the rebound mechanism, and the first spring 19 pushes the push plate 20 and is resisted by the support rod 23, so that the telescopic plug rod 7 drives the support rod 4 to rotate in the opposite direction of the support rod 23 with the rotating block 3 as the center, and the top of the pair of telescopic plug rods 7 drives the bottom of the telescopic plug rod 7 to resist the ground through the elastic thrust of the second spring 21, and at this time, the ladder mechanism forms a triangle with the ground and the support rod 23, and the triangle has good stability in terms of bearing force, thereby evacuating personnel through.

[0031] When the steps on the stepped evacuation platform need to be folded, it is only necessary to rotate a pair of support rods 4 in the direction of the support rods 23 and at the same time hold the telescopic rod 7 upward, so that the second spring 21 in the support rod 4 is compressed and shortened, and finally the button mechanism is pressed downward so that the hook 13 on the button mechanism is re-engaged in the hook groove 14 at the bottom of one of the step plates 5. At this time, the first spring 19 on the rebound mechanism will also be compressed and shortened by the support of the support rods 23, and then the supported pair of telescopic rods 7 are released. The top end of the telescopic rod 7 is subjected to the elastic thrust of the second spring 21, so that the bottom end of the telescopic rod 7 drives the supporting bottom plate 8 to vertically press against the ground, thereby completing the folding of the stepped evacuation platform.

[0032] The preferred embodiments of the utility model of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
