In described rung interior a lock pin mechanism is set, and the described lock pin mechanism includes two end pin bolts which are driven by driving wheel and intermediate driving component, the described intermediate driving component can be used for converting the rotation of driving wheel into axial movement of pin bolts, on the described every pin bolt is respectively set a pin bolt self-locking component.

Description

technical field [0001] The invention relates to a ladder, in particular to a retractable, longitudinally foldable ladder which can be used on uneven ground and which can prevent the ladder from sliding or toppling, and has movable steps and platforms. Background technique [0002] At present, the combined ladders in the prior art have the problems of poor combination and safety to varying degrees, thus resulting in limited application occasions. [0003] The announcement number is CN2261504Y, and the announcement date is September 3, 1997. The Chinese utility model patent discloses a "Multifunctional Combination Ladder", which is a pair of herringbone ladders after connecting two independently used single ladders through hinge connections. , through threaded fasteners and auxiliary feet set in the legs of the ladder, the height of one of the ladders can be adjusted at will, so that it can be used in stairwells or uneven grounds. The disadvantages of this structural ladder a...
