Upright series-connection fire ladder
The invention discloses an upright series-connection fire ladder. A stable base is matched with and fixed to an outer conical surface at the lower end of a stand column body through a middle inner conical hole, and an outer conical surface of the stand column body is matched with and fixed to an inner conical surface of an inner conical hole of another stand column body; after the inner conical hole of each stand column is well matched with and fixed to the outer conical surface of the corresponding stand column, each inner conical surface and the corresponding outer conical surface which are well attached are automatically locked through matching of a locking groove and a braking pin on the corresponding outer conical surface; foot stands are fixed to the surface of each stand column body and are bonded with anti-skid glue, and the bottom of the stable base is coated with anti-slip glue. The upright series-connection fire ladder is simple in structure and very convenient to manufacture, assemble and use, and tools are not needed in the assembly and disassembly processes of the ladder when the ladder is used; after the upright series-connection fire ladder is used, the problem that firefighters have difficulty in climbing uprightly is solved, the fire ladder can be assembled quickly, conveniently, safely and reliably when the firefighters climb uprightly, and the firefighters climb the ladder conveniently; when not needed, the fire ladder is disassembled, packed and transported conveniently, and the production cost and the use cost are reduced.
