[0028] Example 1: Reference Figures 1-3This utility model provides an embodiment of a combined emergency rescue ladder, comprising two lower fixed rods 1. An assembly groove is provided at the rear bottom of each lower fixed rod 1, allowing the upper fixed rod 2 and lower fixed rod 1 to be separated. A movable groove 14 is provided at the rear end of each lower fixed rod 1, allowing a movable block 11 to move at the rear end of the lower fixed rod 1, thereby adjusting the overall length of the ladder. Multiple limiting grooves 13 are provided on the inner wall of the movable groove 14, limiting the position of the limiting block 12, thus facilitating the fixing of the position of the upper fixed rod 2. A movable block 11 is slidably connected within the movable groove 14, with its rear end fixedly connected to the upper fixed rod 2. The top and rear ends are fixedly connected to a limiting block 12, which is located within a limiting groove 13. Multiple fixing blocks 9 are rotatably connected to the adjacent sides of the two lower fixing rods 1 and the two upper fixing rods 2. A left rotating plate 5 is fixedly connected to the bottom end of the left fixing block 9, and a right rotating plate 6 is fixedly connected to the bottom end of the right fixing block 9. The left end of the left rotating plate 5 has the left fixing block 9 as its rotation center point, and the right end of the right rotating plate 6 has the right fixing block 9 as its rotation center point. Fixing blocks 7 are fixedly connected to the bottom right side of the left rotating plate 5 and the bottom left side of the right rotating plate 6. The right end of the left rotating plate 5 has its connection point with the connecting rod 8 as its rotation center point, and the left end of the right rotating plate 6 has its connection point with the connecting rod 8 as its rotation center point. A connecting rod 8 is rotatably connected to the adjacent sides of the two fixing blocks 7.

[0029] Example 2:

[0030] As one of the optimized structural designs for Example 1, such as Figures 1-4 As shown, handrails 3 are fixedly connected to the opposite sides of the two lower fixed rods 1 and the opposite sides of the two upper fixed rods 2. These handrails 3 facilitate support for workers during climbing, thus improving stability. Protrusions 10 are fixedly connected to the bottom sides of the opposite ends of the left and right rotating plates 5 and 6. These protrusions 10 limit the movement of the left and right rotating plates 5 and 6, preventing them from continuing to rotate after reaching a suitable position. Hooks 4 are fixedly connected to the top of the upper fixed rods 2. These hooks 4 facilitate securing the top of the upper fixed rods 2, thus improving the overall stability of the ladder during climbing. The dimensions of the moving groove 14 are compatible with the dimensions of the moving block 11. The dimensions of the limiting groove 13 are compatible with the dimensions of the limiting block 12.

[0031] Working principle: first, the two hook rod 4 rear end hooking the top edge of the place of climbing, and then by lifting the lower fixed rod 1 a distance, so that the limit block 12 in the limit slot 13 can move forward and backward, and move the lower fixed rod 1 forward, so that the limit block 12 from the front end of the limit slot 13 to the rear end of the limit slot 13, then by pulling the lower fixed rod 1 down, so that the moving block 11 from the bottom end of the lower fixed rod 1 to the top end of the lower fixed rod 1, thereby increasing the overall length of the ladder, to facilitate the staff to climb, when using the ladder, the moving block 11 is slid to the bottom end of the lower fixed rod 1 by the above method, thereby shortening the overall length of the ladder, and then moving the two lower fixed rod 1 and the upper fixed rod 2 to the middle, so that the left end of the lower fixed rod 1 and the upper fixed rod 2 push the left rotating plate 5 to rotate, the right end of the lower fixed rod 1 and the upper fixed rod 2 push the right rotating plate 6 to rotate, so as to fold the left rotating plate 5 and the right rotating plate 6, further reducing the occupation space of the ladder, so as to facilitate the staff to carry and transport, by pulling the moving block 11 and the limit block 12 out of the assembly slot, so that the lower fixed rod 1 and the upper fixed rod 2 can be separated, so that the lower fixed rod 1 and the upper fixed rod 2 can be used separately, improving the flexibility of the ladder.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
