Detailed Description

The utility model will be further described with reference to the following figures and specific examples, but the scope of the utility model is not limited thereto.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience in describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "mounted," "connected," "fixed," and the like are to be construed broadly and may include, for example, fixed connections, removable connections, or integral connections, direct connections, indirect connections through intervening media, and communication between two elements; the specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, 2 and 3, the telescopic scaffold for a stepped space according to the present invention includes a telescopic construction platform 1, a column 2, a support pillar 3, a telescopic rod 4, a slot 5, a reinforcing cross bar 6, a roller 7, and an anti-toppling bracket 8.

As shown in fig. 1 and 3, the whole telescopic construction platform 1 is of a box-type structure with an open top, and is formed by splicing a plurality of telescopic plates with concave cross sections, and a group of upright posts 2 with the same height are symmetrically welded on the lower surface of each telescopic plate; the heights of a plurality of groups of stand columns 2 on the lower surface of the telescopic construction platform 1 are sequentially increased from back to front, so that the height of the stand columns 2 is matched with the height of steps in a step space. A group of upright posts 2 positioned at the front end of the scaffold are support posts 3, two reinforcing cross rods 6 are welded between the support posts 3, and the height of the group of support posts 3 is the same as that of the adjacent group of upright posts 2; the bottom of all the upright posts 2 is provided with a roller 7 with a locking device.
