Description

Escape ladder Technical Field The utility model relates to the technical field of escape ladders, in particular to an escape ladder. Background The escape ladder is an auxiliary device for quick downward withdrawing of personnel in emergency of building, and can be quickly unfolded and supported by window or balcony in emergency of fire disaster, earthquake, etc However, the escape ladder in the prior art still has some defects, for example, the grapple of the escape ladder is usually of a fixed size and cannot be adjusted, and is difficult to be compatible with different wall thicknesses and window frame widths, so that the overall installation stability and reliability are affected due to incapability of being firmly clamped on a plurality of buildings, meanwhile, the pedal is too tightly attached to the wall surface, a user cannot find a proper landing point due to too small distance between the pedal and the wall surface when getting off the escape ladder, the difficulty of lowering is increased, and secondary injury is possibly caused due to stepping on the ground, so that the escape ladder is proposed. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an escape ladder, which solves the problems in the prior art. The technical aim of the utility model is realized by the following technical scheme: The escape ladder comprises two support frames, a mounting assembly and a lifting assembly, wherein the two support frames are fixedly provided with reinforcing pipes, one side of each support frame is provided with a plurality of pedals, one side of each support frame is provided with an iron chain, and the mounting assembly is arranged on the left side and the right side of each pedal and used for mounting the corresponding pedal. Through adopting above-mentioned technical scheme, through setting up installation component for make compatible different wall thickness of this emergency ladder and window frame width, and then stable installation, in order to wait the follow-up use. Preferably, the mounting assembly comprises two side blocks, the two side blocks are respectively and fixedly mounted on the left side and the right side of the pedal, a thread groove is formed in one side of each of the side blocks and one side of each of the support frames, a bolt is connected to the inner threads of the thread groove, and the bolts are sleeved with the iron chains.
