[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 1-Figure 7 A portable ladder comprises a first round rod 1, a first connecting component 2 is arranged on one side of the first round rod 1, a second connecting component 3 is arranged on the side of the first round rod 1 away from the first connecting component 2, and the first connecting component 2 and the second connecting component 3 are rotatably connected through the first round rod 1.

[0038] Through the above structural design, it can be known that when the photovoltaic equipment needs to be installed, the first connecting component 2 and the second connecting component 3 can be fully unfolded, and the second connecting component 3 can be connected to the frame for installing the photovoltaic equipment, and the motor 8 inside the first slots at both ends of the lower end of the first ladder frame 4 can be started, and then the start of the motor 8 drives the screw 9 to rotate with the center of the circle of the output end of the motor 8 as the axis. While the screw 9 rotates, the screw 9 rotates inside the connecting groove 26. Through the connection between the screw 9 and the connecting groove 26, when the screw 9 rotates, the screw 9 drives the first connecting column 6 to move downward inside the first slot, and then while the first connecting column 6 moves downward, the first connecting column 6 drives the plug-in column 25 to be inserted into the soil layer on the ground. Through the slope of the ground, the ladder can be fixed by two first connecting columns 6 extending out at different lengths, thereby improving the stability of the ladder.

[0041] Through the above structural design, it can be known that when it is necessary to connect the second connecting component 3 to the frame on which the photovoltaic device is installed, the length of the third connecting component 11 extending out can be adjusted according to the height of the frame.

While pressing the plug-in blocks 17 at both ends of the spring 27 into the first slide groove 15, the plug-in blocks 17 at both ends of the spring 27 squeeze the spring 27, and the spring 27 stores the squeezing force. After the plug-in block 17 slides into the first slide groove 15, the plug-in block 17 and the plug-in groove 12 The plug-in connection is separated, and then the second connecting column 14 is pulled to the outside of the third slot, and then when the second connecting column 14 is pulled to the specified position, the spring 27 releases the stored force to push out the plug-in blocks 17 at both ends, and then the pushed-out plug-in blocks 17 are plugged into the plug-in slot 12, and the movement of the second connecting column 14 can be limited by the plug-in connection between the plug-in blocks 17 and the plug-in slot 12, and then after the position of the second connecting column 14 is fixed, the second ladder frame 10 can be lifted to drive the two first slide slots 15 to be connected to the frame body, thereby completing the connection between the second connecting component 3 and the frame body.

[0042] Embodiment 2:

[0043] The portable ladder provided in Example 1 is further optimized. Specifically, Figure 1 , Figure 6 , Figure 8 As shown, the limiting mechanism 13 includes a fixed block 20, and the number of the fixed blocks 20 is two. The two fixed blocks 20 are respectively fixed at the positions of the upper and lower ends inside the fourth slot, and a second round rod 21 is arranged between the two fixed blocks 20. The two ends of the second round rod 21 are respectively fixedly connected to the fixed blocks 20 at the two ends, and the first connecting block 19 is rotatably connected to the outer side of the second round rod 21 and located between the two fixed blocks 20. The two ends of the first connecting block 19 and the outer side of the second round rod 21 are fixedly connected with a torsion spring 22, and one end of the torsion spring 22 away from the first connecting block 19 is fixedly connected to the fixed block 20 at the same end, and the outer side of the first connecting block 19 is fixedly connected with a second connecting block 23, and the second connecting block 23 is rotatably connected to the fixed block 20, and one end of the second connecting block 23 away from the first connecting block 19 is fixedly connected to the limiting block 24.

[0044] Through the above structural design, it can be known that when it is necessary to limit the folding of the first connecting component 2 and the second connecting component 3, after the photovoltaic equipment is installed, the second ladder frame 10 can be rotated with the center of the first round rod 1 as the axis to close with the first ladder frame 4. When the second ladder frame 10 approaches the first ladder frame 4, the first ladder frame 4 squeezes the inclined surface of the limit block 24, so that when the limit block 24 is squeezed, the limit block 24 drives the second connecting block 23 to rotate with the center of the second round rod 21 as the axis through the first connecting block 19. Through the rotation of the first connecting block 19, the first connecting block 19 squeezes the torsion springs 22 at both ends, and then the torsion springs 22 store the squeezing force. When the second ladder frame 10 is in contact with the first ladder frame 4, the torsion spring 22 releases the stored force to drive the second connecting block 23 and the limit block 24 to reset. Through the reset of the limit block 24, the closing of the first ladder frame 4 and the second ladder frame 10 can be limited.
