[0021] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A ladder structure of a prefabricated cabin, see Figures 1 to 5 , including a cabin body 1, the four corners of the cabin body 1 are all chamfered, and an upper fixed frame 21 and a lower fixed frame 2 are respectively installed on the upper and lower sides of the exterior of the cabin body 1, and a rectangular slot 22 is provided at the opposite ends of the upper and lower fixed frames 21 and the lower fixed frames 2. A ladder 3 is provided between the upper and lower fixed frames 2, and connecting shafts 31 are installed on both sides of the upper and lower ends of the ladder 3, and the other ends of the four connecting shafts 31 are rotatably connected to guide wheels 32; adjustment slots 41 are provided on both sides of the rear end of the ladder 3, and the outer diameter of the guide wheel 32 is adapted to the width of the rectangular frame, and the bottom ends of the inner cavities of the two adjustment slots 41 are slidably penetrated by an insertion rod 4, so A plurality of insertion holes 23 are provided on the lower fixed frame 2 on one side of the rectangular groove 22, and the insertion rod 4 is adapted to the insertion hole 23. When working, the guide wheel 32 is limited in the rectangular groove 22, and the connecting shaft 31 is rotated and connected with the guide wheel 32, so that the ladder 3 is rotated around the cabin body 1 to adjust the position of the ladder 3, so that the ladder 3 can be adjusted to any position around the cabin body 1, and then it can be laid at different heights at the outside of the cabin body 1, further improving the applicability of the ladder 3, and when the ladder 3 is adjusted to a suitable position, the insertion rod 4 is inserted into the insertion hole 23, so that the ladder 3 in use can be adjusted to be limited, thereby improving the stability of people when using the ladder 3.

[0023] For details, see Figure 5 , springs 42 are installed on the top of the inner cavity of the two adjustment slots 41, and the other ends of the two springs 42 are respectively connected to the two insertion rods 4. The springs 42 are always in a compressed state, and the elastic force of the springs 42 is greater than the friction force connecting the insertion rod 4 and the ladder 3. The elastic force of the springs 42 pushes the insertion rod 4 into the socket 23, thereby improving the stability of the insertion rod 4 into the socket 23, and further ensuring the stability of the ladder 3 when in use.

[0024] For further information, see Figure 3 A toggle rod 5 is fixedly connected between the two insertion rods 4, and the toggle rod 5 is convenient for a person to hold and toggle the two insertion rods 4 out of the insertion holes 23 to adjust the position of the ladder 3.

[0025] It is worth mentioning that see Figure 2The outside of the climbing rod of the ladder 3 is fixedly connected with an anti-slip pad 33, which increases the friction when a person stands on the climbing rod of the ladder 3 when using the ladder 3, further improving the stability of the person standing on the climbing rod of the ladder 3 when using the ladder 3.
