Embodiment Construction

[0022] As shown in the figure, a single-leg automatic retractable ladder includes a ladder column, several horizontal ladders fixedly arranged between the ladder columns, automatic telescopic components fixedly arranged in the ladder column, and fixed on the ladder column. The snap-on part and the air pressure control part fixedly arranged on the ladder column.

[0023] The automatic telescopic component includes a fixed piece, a sliding space, a telescopic foot, a pneumatic space, a push rod, a locking gear, a mounting fixture, a pneumatic telescopic rod, and an air pipe. The fixing piece is mainly fixed on the ladder column to fix the parts in the automatic telescopic part; the sliding space is fixed on the fixing piece, and the telescopic foot slides in the sliding space, which mainly makes the telescopic foot move linearly; the air pressure space It is fixed on the fixing part, and the air pressure space mainly plays the role of sealing other things; the push rod is fixed ...

Abstract

The invention discloses a ladder, which comprises a ladder column, a ladder column, a plurality of horizontal ladders fixedly arranged between the ladder column and the ladder column, automatic telescopic parts symmetrically fixed in the ladder column, and symmetrically fixedly arranged on the ladder column. The buckle part and the air pressure control part are arranged symmetrically and fixedly on the ladder column. It can adapt to uneven ground through its own stretchability and the bracket of the ladder feet can prevent tilting and sliding, which enhances the safety factor of the ladder.

Description

technical field [0001] The invention relates to a ladder, which can be automatically adapted to the uneven ground, namely a ladder that can be automatically extended and retracted with one foot, slip-proof and anti-overturning for use on uneven ground. Background technique [0002] At present, the existing ladders are generally used on the plane, but for some work occasions, the ground is uneven, the fulcrums of the ladder are not located on the same plane, and some fulcrums become suspended, and there will be safety problems when working on the ladder. When the ladder is in use, there is a possibility of slipping and tilting. To sum up, there are the following problems in the prior art: when the ground is uneven, some fulcrums of the ladder become suspended, and the ladder cannot support the ground. The problem of job insecurity. SUMMARY OF THE INVENTION [0003] The invention relates to a ladder, which can be automatically adapted to the uneven ground, namely a ladder ...
