Abstract:
A splicable ladder, comprising a main ladder (1) and an auxiliary ladder (2). An upper end of the main ladder (1) and an upper end of auxiliary ladder (2) are detachably connected to form a "人"-shaped ladder by means of a suspension hook (23). First handrails (11) of the main ladder (1) are provided thereon with sliding guide rails (111) and hanging hooks (112) along the height direction thereof, and second handrails (21) of the auxiliary ladder (2) are provided thereon with guide sheaves (211) and hanging rings (212) along the height direction thereof. The cooperation of the sliding guide rails (111) and the guide sheaves (211) enables the main ladder (1) and the auxiliary ladder (2) to move relative to each other when connected to form a straight ladder. The cooperation of the hanging hooks (112) and the hanging rings (212) enables the main ladder (1) and the auxiliary ladder (2) to be fixed relative to each other. The present splicing ladder is adjustable in length and has flexible usage occasions.
