[0018] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0019] A folding ladder that is easy to unfold includes a first ladder 2 and a second ladder 3.

[0020] The upper sides of the first ladder 2 and the second ladder 3 are respectively provided with support rings 12, and the support rings 12 are rotatably connected to the support shaft 1. The upper sides of the first ladder 2 and the second ladder 3 are respectively provided with insertion holes, and the insertion holes are respectively fixedly provided with limit shafts 11. The upper ends of the limit shafts 11 in the insertion holes of the first ladder 2 are respectively fixedly connected to the second arc-shaped connectors 6, and the upper ends of the limit shafts 11 in the insertion holes of the second ladder 3 are respectively fixedly connected to the first arc-shaped connectors 4. The other ends of the first arc-shaped connectors 4 and the second arc-shaped connectors 6 are respectively provided with pressing blocks 5, and the corresponding pressing blocks 5 can fit together and press against each other.

[0021] In this embodiment, by setting a first ladder 2 and a second ladder 3, with the support shaft 1 as the center, rotating the first ladder 2 and the second ladder 3 drives the support ring 12 to rotate, so that the two ladders gradually unfold. As the unfolding angle of the ladders increases, the first arc-shaped connector 4 and the second arc-shaped connector 6 located on the upper insertion hole of the ladder on both sides move accordingly, and the pressing blocks 5 at their ends approach each other and finally fit together and press.

[0022] The extrusion block 5 is a rubber block.

[0023] The first arc-shaped connector 4 and the second arc-shaped connector 6 are respectively fixedly provided with fixing blocks 7 on their upper sides. Each fixing block 7 is passed through by a screw 9. One end of each screw 9 is fixedly connected to one end of an L-shaped rod 10. The other ends of adjacent L-shaped rods 10 are rotatably connected. The screw 9 is threadedly connected to a nut 8.

[0024] By setting the fixing block 7, the screw 9 and the L-shaped rod 10, it is convenient to limit the first arc-shaped connector 4 and the second arc-shaped connector 6 when the nut 8 locks the screw 9. Since the nut 8, the screw 9 and the L-shaped rod 10 are stationary, the first arc-shaped connector 4 and the second arc-shaped connector 6 are both limited.

[0025] The working process of this utility model is as follows:

[0026] Hold the first ladder 2 and the second ladder 3 at appropriate positions with both hands, slowly rotate and gradually unfold the ladders, adjust the unfolding angle in time according to the required operation height, and observe whether the extrusion blocks 5 of the first arc-shaped connecting piece 4 and the second arc-shaped connecting piece 6 are tightly fitted, gently shake the ladders, check the overall stability, and slightly adjust the unfolding angle if there is looseness.

[0027] If the stability of the ladders is insufficient, such as using on soft ground or ground with a certain slope, screw the nut 8, apply pressure to the arc-shaped connecting pieces through the screw rod 9 and the L-shaped rod, enhance the rigidity of the ladders, and pay attention to the change of the stability of the ladders in the process to avoid excessive tightening and damage to the components.

[0028] After confirming the stability of the ladders, the user steps on the ladder pedal, holds the ladder handles on both sides with both hands, slowly climbs, keeps the body center of gravity stable during the operation, and tries to avoid violent shaking.

[0029] If necessary, a person can be arranged to assist in stabilizing the ladders below, pay attention to the operation at any time, and ensure safety.

[0030] After the operation is completed, the user carefully gets off the ladders, ensures that the user is stable, unscrews the nut 8 to loosen the pressure of the L-shaped rod on the arc-shaped connecting pieces, holds the ladders with both hands, slowly rotates the supporting ring 12, and folds the first ladder 2 and the second ladder 3 close to each other.

[0031] The above disclosure is only a specific embodiment of the utility model, but the utility model is not limited to this, and any change that can be thought of by any person skilled in the art should fall within the protection scope of the utility model.
