specific Embodiment approach
[0104] Specific embodiments: In the normal state of the deformed staircase, all the pedals 32 are in a horizontal state, and only when deformation is required, the pedals 32 will be deformed into an inclined state. For the assembly of the deformed staircase of the present invention: the countertop at the entrance of the residential building is generally higher than the ground, and a square pit for placing the deformed staircase is required on the ground. After the deformed staircase is placed and entered, the end step mechanism 4 in the deformed staircase The pedal 32 in the ladder will be higher than the ground for a certain distance, so that the pedal 32 in the end step mechanism 4 is in an inclined state and forms a small slope after contacting the ground, which is convenient for pushing the wheelchair up; The platform at the door, and the pedal 32 in the first step mechanism 1 can be lower than the platform for a certain distance, so that the pedal 32 in the first step mech...

The invention belongs to the technical field of staircases, and particularly relates to a deforming staircase used for constructional engineering. The deforming staircase comprises a first step mechanism, a second step mechanism, a third step mechanism, a tail step mechanism, a base, a second supporting plate, a first supporting plate, a driving gear and a limiting block. The first step mechanism,the second step mechanism, the third step mechanism and the tail step mechanism synchronously act through a connecting strip; taking the first step mechanism as an example, when an executing mechanism is at the initial stage of clockwise rotation of a first gear, a U-shaped plate can be disengaged from limiting for a fixing block, it is guaranteed that a rotating shaft can drive a supporting rodto rotate, and thus a pedal rotates from the horizontal state to the oblique state; as for a swinging mechanism, a partition plate can block a gap between every two adjacent pedals, and thus the protecting effect on a person going up the staircase is achieved; and sliding long blocks automatically slide in hinging blocks under extrusion, thus the phenomenon that every two adjacent pedals cannot rotate and tilt simultaneously is avoided, and overall operation of the swinging mechanism is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of stairs, in particular to a deformed staircase used in construction engineering. Background technique [0002] At present, the traditional entrances of residential buildings generally have small stairs with three to five steps for residents to enter and exit; now civilized society advocates humanized design, and there are special wheelchairs for the disabled on the side of the small stairs at the entrances of many newly-built residential buildings There is a small slope so that the disabled can freely enter and exit the entrance door with steps. However, for many residential buildings that lack humanized design in the past, there are only small stairs for normal people at the entrance, which has caused great trouble for the disabled to use wheelchairs to enter and exit such residential buildings. In order to enable the handicapped to use a wheelchair to go up and down the small stairs at the entrance, so ...
