Firefighting upright special-purpose ladder
The invention relates to a firefighting upright special-purpose ladder. A pin seat is fixed on the pedestal of the ladder, a rotary pin is connected to the pin seat and a rotary seat, a locking screw locks the angle between the pedestal and the rotary seat, the outer conical surface of a pillar body cooperates with the inner taper hole of the rotary seat or the inner conical surface of an inner taper hole on a pillar body bellow so as to be fixed, the inner tape hole and the outer conical surface cooperate and are fixed, then through cooperation of an annular braking groove on the inner conical surface and a banking pin, the well laminated inner conical surface and outer conical surface can be locked automatically. Folded-type pedals able to be drawn in toward one end of the pillar body's connection head are fixed on two sides of the pillar body surface, and an antiskid glue is adhered to the bottom of the pedestal. The firefighting upright special-purpose ladder provided by the invention has the characteristics of simple structure, convenient carry, and no need of tool during assembly and disassembly in use, solves the problems of upright climbing and standing during firefighting emergency and rescue. During climbing of the assembled ladder, the speed is fast, and the ladder is safe and reliable, and is convenient to climb. And after use, the disassembly, packaging and transportation are convenient.
