Described supporting leg comprises the supporting leg sleeve, is threaded the tapered round platform lower margin and the leading screw in hole, is fixedly connected with nut in supporting leg sleeve lower end, leading screw pass the supporting leg sleeve and on nut be connected with tapered round platform lower margin, leading screw upper end is connected with nut.
The material of described pedal is a tempered glass, and the lower end of described pedal is connected with metal tray, and described metal tray is connected with pedal auxiliary girder screw with gripper shoe respectively.
The lower end of described core pipe is fixedly connected with cross frame.
Described protecting blocked lower margin and is two ground leg structure.
Each sleeve is provided with core pipe jackscrew.
The utlity model has following technique effect:
Since the pedal strong point around, the strong point is many, Area of bearing is big, pedal is stressed evenly, and is not yielding, long service life.
2. because guardrail is installed in the pedal outside by supporting lower margin, enlarged the usage space of stair, and, safeguarding, when changing pedal, can having simplified maintenance process, use more convenient without the dismounting guardrail.And the guardrail lower margin is two ground leg structure, and is more firm.
3. owing to the material that adopts tempered glass as pedal, not easy to wear, non-maintaining.And, elegant in appearance.
4. be provided with height-adjustable support column in the lower end, unit of marking time of the bottom, make stair not produce vibration in use, more stable.
Since a plurality of sleeves connect by the core pipe in aggregates, and, can regulate gap between each sleeve by regulating the core pipe, make the maintenance of whole stair more convenient, stair are more stable.
6. owing on sleeve, being provided with core pipe jackscrew, more stable between core pipe and the sleeve, firm.
