DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0025] like Figure 1 As shown, the utility model proposes a foldable evacuation platform, including a mounting frame 1, a mounting frame 3 is hinged on the mounting frame 1, so that the mounting frame 3 can be rotated on the mounting frame 1, so that the mounting frame 3 can be folded to reduce the occupied space, and also includes:

[0026] Among them, a support plate 7 is slidably installed in the installation frame 3, and a limiting mechanism for fixing the support plate 7 is provided in the installation frame 3, so that the support plate 7 can be fixed in the installation frame 3 and will not slide out of the installation frame 3. At the same time, the support plate 7 can also be taken out, which is convenient and quick, and improves the stability of the equipment.

[0027] like Figure 3-6 As shown, the limiting mechanism includes protrusions 9 fixedly installed on both sides of the support plate 7, and slide grooves 17 are provided on both sides of the installation frame 3. The protrusions 9 are located in the slide grooves 17. The protrusions 9 are provided with a first limiting groove 11. A connecting rod 5 is slidably installed on the installation frame 3. The connecting rod 5 is provided with a second limiting groove 12. The second limiting groove 12 presses against the first limiting groove 11. First springs 10 are fixedly installed at both ends of the connecting rod 5. The first spring 10 is fixedly connected to the installation frame 3. When the support plate 7 needs to be taken out, the connecting rod 5 is pressed inwardly, and the connecting rod 5 drives the first spring 10 to be compressed. As the connecting rod 5 moves inward, the first limiting groove 12 is pressed against the first limiting groove 11. The second limiting groove 12 no longer presses against the first limiting groove 11, and the support plate 7 can be taken out at this time. When the support plate 7 needs to be installed, the connecting rod 5 is pressed inwardly, the first spring 10 is deformed, and the support plate 7 is placed in the installation frame 3 at the same time. When the placement is completed, the pressure on the connecting rod 5 is cancelled, the first spring 10 rebounds, and drives the connecting rod 5 to move outward. At this time, the second limiting groove 12 presses against the first limiting groove 11 to fix the support plate 7, and the fixing effect is good. The support plate 7 is placed and slides out of the installation frame 3. At this time, an elastic mechanism is provided in the installation frame 3 to assist in moving out the support plate 7, so that the support plate 7 is convenient to take out.

[0032] Working principle: When emergency evacuation is needed, rotate the limit plate 4 to cancel the fixation of the installation frame 3, and rotate the installation frame 3 to evacuate. When the installation frame 3 needs to be folded, rotate the installation frame 3, and then rotate the limit plate 4 to fix the installation frame 3. When the support plate 7 needs to be taken out, press the connecting rod 5 inward, and the connecting rod 5 drives the first spring 10 to compress. As the connecting rod 5 moves inward, the second limit groove 12 no longer presses against the first limit groove 11. When the second limit groove 12 on the connecting rod 5 cancels the pressure on the first limit groove 11, the second spring 16 rebounds and drives the limit block 13 to press the support plate 7, and the limit block 13 pops out the support plate 7. When the support plate 7 needs to be installed, the connecting rod 5 is pressed inward, the first spring 10 is deformed, and the support plate 7 is placed in the installation frame 3 at the same time. When the placement is completed, the pressure on the connecting rod 5 is cancelled, the first spring 10 rebounds, and drives the connecting rod 5 to move outward. At this time, the second limit groove 12 presses the first limit groove 11 to fix the support plate 7, which realizes the folding of the equipment and is convenient for later maintenance, reducing labor, and the equipment is stable, easy to disassemble and assemble, and has strong practicality.
