AI Technical Summary
The support structure of the existing folding ladder is poorly stable, easy to tilt, and insufficient anti-slip effect, resulting in potential displacement during use.
A folding ladder including a climbing frame, a support frame and a hinge frame is designed, and a combination mechanism (including a first flip support, a locking plate, a second flip support, a reinforcement pad and a locking screw) is used to enhance support stability, and an anti-slip pad is installed at the bottom of the reinforcement pad to improve the anti-slip effect.
Through the design of the combination mechanism, the support stability of the folding ladder is enhanced and the risk of accidental folding is reduced. At the same time, the anti-slip pad effectively increases the anti-slip area, avoiding the potential for displacement of the folding ladder during use.

The supporting structure is relatively simple, and the load-bearing support has the problem of poor stability when in use. In particular, when the folding ladder is in use, there is a safety hazard of tipping over when the two brackets are accidentally folded. In addition, the small anti-skid pads at the bottom of the two brackets of the folding ladder cannot effectively achieve a good anti-skid effect. Therefore, the folding ladder has the trouble of shifting on the ground when subjected to irregular shaking.
[0004] Therefore, a folding ladder for power maintenance is needed to solve the problems in the prior art that the folding ladder is mainly supported on the ground by two open brackets, which has poor stability and the potential for tipping due to the accidental folding of the two brackets.
