The invention discloses an antislip herringbone ladder which comprises two ladder beds. An end of one ladder bed is hinged to an end of the other ladder bed, each ladder bed comprises two parallelly erected side plates and a plurality of treadles, and the treadles of each ladder bed are transversely connected to positions between the two side plates of the ladder bed. The antislip herringbone ladder is characterized in that suckers are arranged at the lower ends of the side plates of the two ladder beds, sucking surfaces of the suckers face the ground, and communicated ventilation pipes are arranged between the two suckers on the same ladder bed and are communicated with air bags on the side surfaces of the side plates of the ladder bed. Compared with the prior art, the antislip herringbone ladder has the advantages that excellent antislip effects can be realized by the aid of the suckers at the lower ends of the ladder beds of the antislip herringbone ladder on the smooth ground, and accordingly the service safety of the antislip herringbone ladder can be improved.
