Embodiment Construction
[0069] The fire fighting vertical ladder of the present invention mainly includes base 16, pin seat 17, locking screw 18, rotating pin 15, movable seat 1, gravity cone 19, upright column body, locking hole 5, locking pin 6, thrust spring 7, locking bar 4. Sliding hole 9, lock groove, outer tapered surface 10, inner tapered hole 12, inner tapered surface 11.
[0070] The pin seat 17 is fixed on the base 16, and the pin hole 14 and the locking screw hole are arranged on the pin seat 17. Seat 17 and movable seat 1 are connected together, and locking screw 18 is screwed into the locking screw hole on the pin seat 17, and the screw end of locking screw 18 that exceeds the locking screw hole is pressed against the lower part of movable seat 1 to lock the activity. The matching angle between the seat 1 and the base 16; the above movable seat 1 has an inner cone hole 12, and there is an air gap 8 under or inside the inner cone hole 12, and the middle part of the bottom of the air gap ...

Abstract
The invention relates to a firefighting vertical ladder. A pin seat is fixedly arranged on a base, a rotating pin connects the pin seat with a movable seat, an angle between the base and the movable seat is adjusted by utilizing a gravity cone and is locked by utilizing 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 in a sticking manner, and the lower surface of the movable seat is also provided with antiskid adhesive. The firefighting vertical ladder is simple in structure and very convenient to manufacture, assemble and use, and a tool is not required in the assembling and dismounting process of the ladder during use; after the firefighting vertical ladder is adopted, the condition that firefighting personnel can difficultly vertically climb and stand on the oblique ground can be solved, the firefighting personnel is convenient to climb, the climbing assembling speed is high, and the convenience and the reliability in assembling can be realized; after the firefighting vertical ladder is used, the convenience in dismounting, packaging and transportation can be realized, and the production cost and the application cost can be reduced.
