An assembled ladder includes two supporting leg assemblies, at least one rung and a bridging part, wherein each supporting leg assembly of the two supporting leg assemblies includes a front supporting leg and a rear supporting leg rotatably connected to the front supporting leg, and the at least one rung and the bridging part are detachably connected between the two supporting leg assemblies. During logistics transportation, the at least one rung is detached from the two supporting leg assemblies, the bridging part is also detached from the two supporting leg assemblies, and the two supporting leg assemblies are stacked. In use, two ends of the bridging part are fixedly connected to the two supporting leg assemblies, and two ends of the at least one rung are also fixedly connected to the two supporting leg assemblies.

Assembled ladder

A lifting positioning structure for a ladder tool platform comprises a ladder. The ladder comprises front supporting legs, rear supporting legs, connectors fixedly connected to the front supporting legs, plug pins, and elastic parts, wherein each front supporting leg includes a big tube and a small tube which are able to relatively move in an extension direction. The connectors are formed with vertically-through installation cavities which allow the big tubes to be inserted therein. The big tubes are arranged in the installation cavities and are fixedly connected to the connectors which extend to form connection parts rotationally connected to the rear supporting legs. The small tubes are connected to a tool platform. The plug pins are movably arranged on the connectors or the big tubes.

Lifting positioning structure for ladder tool platform

A telescopic positioning structure used for a ladder is disclosed. The ladder includes a front supporting leg and a rear supporting leg. The front supporting leg includes a first tube and a second tube, and the first tube and the second tube are able to move relative to each other in an extension direction. The rear supporting leg is rotatably connected with the first tube. The ladder further includes a pin connected with the first tube. When the rear supporting leg is unfolded, an upper end of the rear supporting leg abuts against the pin and drives to the pin to move towards the second tube, and when the pin abuts against the second tube, the second tube is positioned.
