Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b):
referring to fig. 1, for the utility model discloses a movable scaffold, including the support body, the support body comprises vertical pole 3 and horizon bar 4, and the both sides of support body are equipped with the ladder 18 of crawling, and the constructor of being convenient for climbs the scaffold and carries out work. The bottom of support body is equipped with universal wheel 1, can make the scaffold frame remove through universal wheel 1. The vertical pole 3 of scaffold sets up to cylindrical, installs sleeve 5 on the vertical pole 3, and the internal diameter of sleeve 5 is the same with the external diameter of vertical pole 3, is that sleeve 5 can rotate around vertical pole 3. The vertical rod 3 is provided with a limiting device 8 for limiting the position of the sleeve 5, so that the sleeve 5 is sleeved at the fixed position of the vertical rod 3. Be connected with A-frame 6 on the sleeve 5, A-frame 6's the second right-angle side and the nodical department fixedly connected with strutting arrangement 7 of hypotenuse, A-frame 6's stability is stronger, can bear bigger power and not take place deformation. A triangular support 6 and a supporting device 7 can rotate through a sleeve 5 to adjust the angle, so that the triangular support 6 and the supporting device 7 connected on each vertical rod 3 are placed in an X shape, the scaffold is supported in all directions, and the stability of the scaffold is improved. When the scaffold is not applicable, the triangular support 6 and the supporting device 7 can be retracted by rotating the sleeve 5. The support is provided with a tool box 17 which can be used for placing tools commonly used in construction and spare parts needed by a scaffold.
Referring to fig. 2, the limiting device 8 on the vertical rod 3 is provided with a bolt and a nut, the vertical rod 3 is provided with an upper limiting hole 9 and a lower limiting hole, the upper limiting hole 9 and the lower limiting hole 10 are inserted with a bolt, and the bolt penetrates through the limiting hole and then is screwed with the nut. The distance between the upper limiting hole 9 and the lower limiting hole 10 is the same as the length of the sleeve 5, the sleeve 5 is sleeved between the upper limiting hole 9 and the lower limiting hole 10 of the vertical rod 3, and the bolt cap and the nut at the upper limiting hole 9 and the lower limiting hole 10 can block the sleeve 5 to move up and down, so that the sleeve 5 is limited. Avoiding the sleeve 5 moving on the vertical rod 3 when the support means 7 fix the scaffold, thus causing the support means 7 to shake. The vertical rod 3 is horizontally provided with a bolt hole 16, the bolt hole 16 is superposed with the upper and lower positions of the angle bisector of the included angle between two adjacent horizontal rods 4, the sleeve 5 is provided with a fixing hole 19, and the fixing hole 19 and the bolt hole 16 are positioned on the same horizontal plane. When the bolt hole 16 is overlapped with the fixing hole 19, the bolt is screwed into the bolt hole 16 through the fixing hole 19, so that the sleeve 5 is fixedly connected with the vertical rod 3. At this time, the sleeve 5 cannot rotate around the vertical rods 3, and the triangular supports 6 and the supporting devices 7 connected to the vertical rods 3 are fixedly placed in an X shape.
