Abstract

The invention relates to the technical field of ladders, in particular to a buffering structure and an extending ladder. The buffering structure comprises a guiding sleeve which is connected with a ladder, a pressing plate is connected with the guiding sleeve, and an accommodating cavity is formed by the pressing plate and a through hole in the guiding sleeve; an elastic piece is arranged in the accommodating cavity, one side of the elastic piece is in contact with the pressing plate, and the other side of the elastic piece is in contact with a connecting structure; and the connecting structure is connected with a buffering layer. The extending ladder comprises a main ladder frame and an auxiliary ladder frame which is slidably connected with the main ladder frame, and one side of the auxiliary ladder frame is connected with the buffering structure; a plurality of main ladder rungs are arranged on the main ladder frame, and a plurality of auxiliary ladder rungs are arranged on the auxiliary ladder frame; a hook is fixedly arranged on the auxiliary ladder frame, and a lifting rope is connected to the hook; one end of the lifting rope is connected with the top part of the hook, and the other end of the lifting rope is connected with the auxiliary ladder frame after penetrating through the multiple main ladder rungs and rolling wheels in sequence. According to the buffering structure and the extending ladder, the problem that weightlessness is likely to occur when an auxiliary ladder dropped accidently is solved, and damaging for the ladder and injuring for a user are avoided.

Description

technical field [0001] The invention relates to the technical field of ladders, in particular to a buffer structure and an extension ladder. Background technique [0002] Ladders are commonly used climbing tools in daily life, wherein the extension ladder is a ladder that can be stretched and stretched when it is practical, and can be folded and shortened for storage when not in use. Ordinary extension ladder is composed of main ladder and auxiliary ladder. The ladder frames of main ladder and auxiliary ladder are C-shaped profiles or tubular profiles. The auxiliary ladder is interspersed on the main ladder. , There are pulleys on the main ladder. By pulling the rope, the auxiliary ladder can rise or fall freely. This kind of extension ladder can only be used upright, and when in use, it needs to be leaned on a high fixed object. And this kind of extension ladder, when in use, generally all is to operate by two to three people, after being raised to use height, leans on the...
