DETAILED DESCRIPTION

[0012] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0013] like Figure 1 , 2 As shown, the hinged folding scaffolding comprises two pairs of vertical poles 1, a plurality of cross bars 2 are evenly connected between adjacent pairs of vertical poles 1 from top to bottom, A pulley 3 is arranged at the bottom end of the vertical pole 1, the upper part of one of the vertical poles 1 opposite to each other in the two pairs of vertical poles 1 is rotatably connected to a pair of A sub-cross bars 4 through A sleeve 8, the ends of the two A sub-cross bars 4 are connected to the two ends of A sub-vertical poles 5, and the A sub-vertical poles 5 on both sides are rotatably connected through A hinges 7, the lower part of the other vertical pole 1 opposite to each other in the two pairs of vertical poles 1 is rotatably connected to a pair of B sub-cross bars 9 through B sleeve 14, the ends of the two B sub-cross bars 9 are connected to the two ends of B sub-vertical poles 10, and the B sub-vertical poles 10 on both sides are rotatably connected through B hinges 13, and the rotation directions of A hinge 7 and B hinge 13 are opposite.

[0014] One of the B secondary uprights 10 is extended downward to form an extension rod 11, and a B pulley 15 is provided at the bottom end of the extension rod 11. The B pulley 15 is located at the same height as the A pulley 3, which can improve the structural stability when the B hinge 13 is opened and closed.

[0015] A reinforcing rib 6 is provided at the connection between A secondary crossbar 4 and A secondary vertical bar 5, and B reinforcing rib 12 is provided at the connection between B secondary crossbar 9 and B secondary vertical bar 10. The structural stability can be effectively improved.

[0016] The opening and closing directions of the A hinge 7 and the B hinge 13 are both outward, and the length of the A auxiliary upright rod 5 and the length of the B auxiliary upright rod 10 are not greater than the length of the cross bar 2, so they do not protrude from the upright rod 1 when folded.

[0017] According to the above structure, when in use, the overall structure can be moved by the bottom pulley. When it is necessary to open the scaffolding, the A sub-crossbar 4 and the B sub-crossbar 9 are opened outward along the A hinge 7 and the B hinge 13. After opening in place, the pedal (not shown) is connected and it can be used. When it is necessary to fold and transport, the pedal is removed, and the A hinge 7 and the B hinge 13 are folded inward, so that the A sub-crossbar 4 and the B sub-crossbar 9 are folded to the inner side of the two pairs of vertical rods 1 on both sides, so as to reduce the volume and facilitate transportation.

[0018] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
