Portable assembling ladder

The utility model discloses a portable assembling ladder, comprising a ladder top, transverse rods, a ladder seat and movable vertical rods each of which is composed of a sleeve rod and a sliding rod. The sliding rod is arranged inside the sleeve rod and can slide freely. Convex blocks are arranged on the sleeve rod at the connecting points of the movable vertical rod and the ladder seat, contiguous movable vertical rods, and the movable vertical rod and the ladder top. The convex blocks and connectors form the connection of the transverse rod and the ladder seat, the movable vertical rod, and the ladder top. When a ladder is assembled, the sliding rod of the ladder seat is sheathed into the sleeve rod of a contiguous movable vertical rod; the sliding rods of contiguous movable vertical rods are interlaced and sheathed into the sleeve rod of a movable vertical rod in previous section. The sliding rod of the movable vertical rod contiguous to the ladder top is sheathed into the sleeve rod of the ladder top. The utility model has simple structure, the portable assembling ladder can be assembled into a single ladder and a herring bone ladder, in order to adapt different working environments. The component parts can be disassemble into separate units for the convenience of storing and carrying, so the portable assembling ladder solves the problem that an existing ladder has large storage space and inconvenient carrying because the vertical rods and the transverse rods are connected fixedly.
