A two-step step stool includes a primary stool and a secondary stool. The primary stool includes a primary supporting plate and a primary pedal hinged with a top of the primary supporting plate. The secondary stool includes a secondary supporting plate and a secondary pedal hinged with a top of the secondary supporting plate. The secondary pedal is higher than the primary pedal. A middle plate is arranged between the primary stool and the secondary stool and is respectively hinged with the primary pedal and the secondary pedal. A linkage mechanism capable of folding the primary stool and the secondary stool synchronously is further arranged between the primary stool and the secondary stool. The two-step step stool can be drawn close towards the middle plate when being folded by hinging the primary pedal with the middle plate and hinging the secondary pedal with the middle plate.

Two-step step stool

A folding step stool includes a stool surface and a support structure for supporting the stool surface. The support structure is a foldable structure and comprises at least three support shafts. The stool surface is hinged to a rear side of a connecting line of tops of two adjacent support shafts. After being folded, the support structure is located on one side of a plane formed by the two support shafts hinged to the stool surface. After being turned, the stool surface is located on the other side of the plane formed by the two support shafts to which the stool surface is hinged, and the two support shafts are able to abut against the two support shafts to which the stool surface is hinged. The invention solves the problem that step stools in the prior art still have a large size after being folded.

Folding step stool

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.

Telescopic positioning structure used for ladder

A folding locking mechanism used for a step stool is disclosed. The step stool includes a stool plate, stool legs rotatably arranged on the stool plate and a locking mechanism used for locking the stool legs. The locking mechanism includes a first connecting piece and a pin, wherein the first connecting piece is fixedly connected with the stool plate and is provided with a limiting hole allowing the pin to fall therein, and the pin is limited in the radial direction and is movable in the axial direction, relative to the stool legs.
