Abstract
The invention relates to an upright fire ladder. A pin seat is fixedly arranged on a base, a rotating pin connects the pin seat and a movable seat, and an angle between the base and the movable seat is locked by virtue of a locking screw; an inner taper hole of the movable seat or an inner taper hole of a stand column body is matched with the outer tapered surface of the stand column body so as to be fixed; the inner taper hole is matched with a position locking pin by virtue of a locking groove in a locking rod after being matched with the outer tapered surface so as to automatically lock the well-fit inner tapered surface and outer tapered surface; a pedal is fixedly arranged on the surface of the stand column body, the pedal is provided with antiskid adhesive, and another antiskid adhesive is stuck to the lower surface of the movable seat. The upright fire ladder is simple in structure and convenient to manufacture, assemble and use, and a tool is not required in the assembling and dismounting process during the use of the ladder; after the upright fire ladder is adopted, the difficulty for vertically climbing and standing of firemen can be solved, the upright fire ladder is fast, convenient, safe and reliable to assemble during the climbing and is convenient to climb; after the upright fire ladder is used, the upright fire ladder is convenient to dismount, package and transport, and the production cost and the application cost can be reduced.
