2022 in sliding slot 2012 and right first sliding groove, and opposite slide can occur with left plate 201 and right side plate 202；
The independent ladder variable amounts that tread 102 and ladder baffle 103 are formed, and independent ladder and variset 4 are one by one
Corresponding, i.e. the step number of stair can change, and whenever changing the step number of stair, need to change together the quantity of variset 4
Become, while it will be appreciated by those skilled in the art that technical solution of the present invention provide a ladder when scheme, on this basis
When increasing ladder quantity, auxiliary connecting rod 307 can not increase or can even give up, while should be ensured that left sliding panel 305 and right cunning
Movable plate 306 is connected with each pull rod, and left first sliding groove 2012, left second sliding slot 2013, right first sliding groove 2022 and the right side
The quantity of second sliding slot 2023 and the length of left third sliding slot 2014 and right third sliding slot 2024 should also be as changing therewith, change
After step number, it should be appreciated that be located at the most upper of left third sliding slot 2014 and right third sliding slot 2024 in the first above-mentioned pull rod 406
The first pull rod 406 that side or auxiliary connecting rod 307 are located in the bottom of left third sliding slot 2014 and right third sliding slot 2024 can be used
The equivalent replacement of the pull rod of the top, auxiliary connecting rod can be replaced with the pull rod of bottom, to ensure third sliding slot 2014 and the right side
Third sliding slot 2024 is best sliding slot.
The working principle of the invention is as follows with application method:
Under normal circumstances, stair are should be ladder-like, at this point, the first sliding bar 402 and the second sliding bar 403 distinguish equal position
The bottom of 2012, right first sliding groove 2022 and left second sliding slot 2013, right second sliding slot 2023 is slided in a left side first, and first draws
Bar 406 is located at the top of left third sliding slot 2014 and right third sliding slot 2024 or auxiliary connecting rod 307 is located at left third sliding slot
2014 and right third sliding slot 2024 bottom, can guarantee in this way the present invention with common stair indistinction；
Pass through stair when needing to clean stair, robot or wheelchair etc., or even needs between corridor when carry an object, it can
Stair are conjugated into inclined plane shape, complete corresponding task to facilitate；At this point, can by be fixedly installed in some position it is one-touch by
The means such as button, Digiplex or cell phone application are issued to stair control cabinet 301 and are instructed, and after control cabinet 301 receives instruction, will be driven
Dynamic motor 302 rotates, and the structure of left third sliding slot 2014 and right third sliding slot 2024 is determined when direction of rotation is by designing, here
It is rotated in the forward direction by motor 302, for sliding panel 304 moves down, sliding panel, which moves down, will drive the first pull rod 406 and auxiliary
Pull rod 307 moves down, so that left sliding panel 305 and right sliding panel 306 be driven to move down, and then pushes the second sliding bar
403 drive above-mentioned independent ladder around rotation along 2023 upward sliding of left second sliding slot 2013 and right second sliding slot, to reach
Bar is rotated, and the second sliding bar 403 is finally made to be located at 2023 the top of left second sliding slot 2013 and right second sliding slot, motor
302 stop rotating, and have been deformed into inclined-plane state at this time, left connecting rod 404, right connecting rod 405 with left sliding panel 305, sliding panel
304, vertical relation is presented in right sliding panel 306, can then carry out corresponding operation；
After the completion of corresponding operation, command adapted thereto is issued to control cabinet 301, driving motor 302 is inverted, drives sliding panel
304 move up, so that left sliding panel 305 and right sliding panel 306 be driven to move up, and then pull 403 edge of the second sliding bar
2023 slide downward of left second sliding slot 2013 and right second sliding slot, drive above-mentioned independent ladder around rotating bar progress to reach
Rotation, finally makes the second sliding bar 403 be located at 2023 bottom of left second sliding slot 2013 and right second sliding slot, motor 302 stops
Spin-ended turn, the first pull rod 406 or the pull rod of the top are located at left third sliding slot 2014 and right 2024 the top of third sliding slot at this time,
Stair are reformed into ladder-like at this time.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
