[0003] The Chinese invention patent with application number 2009201795015 discloses a bridge maintenance hanging ladder, which is composed of a hook and a ladder. This hanging ladder is simply hung on the wall with a pair of hooks. The connection between the hanging ladder and the wall is not firm, and There are no other safety protection devices, and there are great potential safety hazards for people working on it
[0004] The Chinese invention patent with the application number of 2014200081610 discloses a side hanging ladder, which is composed of a whole frame and a hook, and a protective bar is set on the whole frame. Compared with the bridge maintenance hanging ladder, the hanging ladder of this structure has a higher safety. A certain improvement, but the connection between the hanging ladder and the wall is not firm
[0005] The Chinese invention patent with application number 2007800045941 discloses a ladder docking device. The ladder is provided with a fixing device and a mounting bracket, and the fixing device and the mounting bracket need to be fixed to the wall by screws. Although this method is very difficult to connect the ladder to the wall Fixed, but the installation is very troublesome, and it will damage the wall, this kind of ladder is only suitable for construction sites, not suitable for home use

Embodiment Construction
[0015] Such as Figures 1 to 2 As shown, the inner buckle type hanging ladder of the present invention includes an outer handrail 2 and an inner handrail 3 connected by a connecting rod 1. Steps 4 are arranged on the outer handrail 2 and the inner handrail 3, and on the outer handrail 2 and the inner handrail 3 A group of adjustable support rods 5 supporting the wall are set, an upper platform 6 is arranged at the connection between the connecting rod 1 and the outer handrail 2 and the inner handrail 3, and a guardrail 7 is set on the outer handrail 2, and the guardrail 7 Lower platform 8 is set at the lower end. The adjustable support rods on the outer handrail and the inner handrail are most ideally arranged on the same horizontal plane, so that after tightening, the active forces are relatively opposite, which can make the ladder installation more stable. The adjustable support rod 5 is a screw rod.
[0016] In order to further optimize the above solution, the front end o...
