Problems solved by technology

[0002] The stairs of a multi-storey house are generally built when the building is built. It is constructed with traditional building materials and cannot be moved. It will occupy a large space in the house, making this part of the two-story house an unusable area. The house Low space utilization
Existing folding spiral ladders are mainly horizontally folded and vertically telescopic, but their structural design is not suitable for high-rise houses, and these folding spiral ladders also take up a lot of space after folding, and need to arrange a separate space for storage. solve the problem of space utilization
[0003] Due to its spiral step arrangement, it is more difficult to realize the automatic design of its folding and opening and closing than the traditional straight ladder

Embodiment 1

[0034] When step 2 is unfolded,

[0035] Air is passed into the handrail 4, and the bag-like structure of the handrail 4 is propped up due to the increase in internal pressure, forming a spiral result, and its distribution in the horizontal direction and the vertical direction changes. 3 transmission, driving the steps 2 to rotate in the horizontal direction, and unfolding the steps 2.

[0036] When the step 2 is continuously unfolded, after a certain internal pressure is reached in the handrail 4, there is no need to continue to open the injection drive mechanism, and the stop standard can be determined by the pressure relief valve 17, which can also ensure During use, the handrail 4 is used under load and will not burst due to excessive internal pressure.

Embodiment 2

[0038] When using the steps 2, go upstairs through the steps 2 distributed in a spiral shape. During this process, the gravity of the human body is borne by the base column 1, and the function of the handrail 4 is only to stand on the stairs, and the gravity of the human body will not pass through. The connecting chain 3 is transmitted to the handrail 4, but the handrail 4 has a certain load-bearing capacity and can be used for supporting. When supporting, the connecting chain 3 will bend and will not transmit the pressure to the step 2.

[0039] When walking, due to pedaling on the steps, a horizontal torsion force will be generated. If the torsion force is not offset, it will cause the rotation of the steps 2. The torsion force is offset by two aspects, one is offset by the damping buffer 6, and the other is The reset tension brought by the internal pressure of the handrail 4 is offset.

Embodiment 3

[0041] When there is no need to continue to use the steps, the deflation operation is carried out on the handrail 4, and the handrail 4 will be gradually emptied, and gradually drop from a spiral shape. During the drop process, the counterweight 17 is used to ensure that the steps 2 Realize the reset rotation until the counterweight 17 and the handrail 4 are vertically distributed, and the reset recovery of the steps 2 is completed.

[0042] During the reset process, the step 2 will come into contact with the connecting chain 3. At this time, due to the drooping of the handrail 4, the connecting chain 3 will also become loose. After contacting the step 2, It will become curved and will not cause too much resistance to the reset of the step 2.

[0043] During the step 2 reset process, due to the effect of the damping buffer, the reset process will proceed slowly, and the counterweight 17 will not swing and fall directly, and the step 2 will quickly reset to cause the internal com...

Abstract

The invention provides a folding winding stair for a duplex house. The folding winding stair comprises a base column, steps are mounted on the base column, and the steps are connected to a handrail byconnecting chains. The folding winding stair is characterized in that the steps are rotatably connected to the base column through bearings, damping buffers are mounted in the bearings, the handrailis of a bag-like structure, and a mounting plate is arranged at the end of the handrail. The folding winding stair has the beneficial effects that the opening and closing is realized by an automatic machine, time and labor are saved, the automation of the winding stair is realized through the design of the rotation structure, and at the same time, the damping buffering in the steering direction and the vertical direction is realized; and no load is caused on equipment during unfolding, less space is taken after unfolding, and buffering is realized during climbing stairs.

Description

technical field [0001] The invention relates to the field of motorized stairs, in particular to a folding spiral staircase used in duplex houses. Background technique [0002] The stairs of a multi-storey house are generally built when the building is built. It is constructed with traditional building materials and cannot be moved. It will occupy a large space in the house, making this part of the two-story house an unusable area. The house Low space utilization. Existing folding spiral ladders are mainly horizontally folded and vertically telescopic, but their structural design is not suitable for high-rise houses, and these folding spiral ladders also take up a lot of space after folding, and need to arrange a separate space for storage. solve the problem of space utilization. [0003] Due to its spiral step arrangement, it is more difficult to realize the automatic design of its folding and opening and closing than the traditional straight ladder. Contents of the inve...
