A limiting ring 12 and a second limiting ring 22. The gaps between the first limiting ring 12 and the first cover body 11, and between the second limiting ring 22 and the second cover body 21 are respectively the first slot 13 and the second slot 23. Two vertical steel pipes 3 are respectively inserted into the first slot 13 and the second slot 23. A cross hole 111 is provided at the bottom of the first cover body 11. A cross limiting member 24 adapted to the cross hole 111 is provided on the top of the second cover body 21. The cross limiting member 24 includes a rotating cross block 241 and a fixed cross block 242. The fixed cross block 242 is fixedly arranged on the top of the second cover body 21, and the rotating cross block 241 is coaxially rotatably arranged on the top of the fixed cross block 242.

[0023] When installing the scaffold, first arrange the cover opening of the first connecting cover 1 upward and the cover opening of the second connecting cover 2 downward, then move the first connecting cover 1 downward until the bottom of the first cover body 11 fits with the top of the second cover body 21, so that the cross limiter 24 on the second cover body 21 is inserted into the cross hole 111 of the first cover body 11, and then rotate the rotating cross block 241 to misalign the rotating cross block 241 with the fixed cross block 242, fix the first connecting cover 1 and the second connecting cover 2 in connection, and then complete the plug-in connection of the second slot 23, the first slot 13 and the vertical steel pipe 3 in sequence, the weight of the upper vertical steel pipe 3 will press itself against the first connecting cover 1, and at the same time, will press the second connecting cover 2 against the top of the lower vertical steel pipe 3, and repeat the above steps to complete the installation of the vertical steel pipe 3; the present scaffold realizes the rapid installation of the vertical steel pipe 3 by setting the first connecting cover 1, the second connecting cover 2 and the cross limiter 24, is simple to operate, and does not require additional tools, effectively improving the installation efficiency of the scaffold.

[0024] It should be noted that the thickness of the fixed cross block 242 matches the depth of the cross hole 111, so that the bottom of the first connection cover 1 is limited between the top of the second connection cover 2 and the bottom of the rotating cross block 241 to ensure the stability of the scaffolding connection.

[0025] In a specific implementation, a rotating shaft is embedded in the axis of the fixed cross block 242 , and the rotating cross block 241 is rotatably connected to the fixed cross block 242 via the rotating shaft.

[0026] Embodiment 2 of the utility model is a convenient installation scaffold. On the basis of embodiment 1, the rotation angle of the rotating cross block 241 is 0-90°. At 0° and 90°, the rotating cross block 241 overlaps with the fixed cross block 242. The smaller the rotation angle, the easier it is for construction personnel to adjust. The rotating cross block 241 can be rotated to any angle between 0° and 90° to enable the rotating cross block 241 to achieve the limit function. In specific implementation, the rotating shaft is provided with limit blocks at 0° and 90° to prevent the rotating shaft from rotating excessively.

[0027] Embodiment 3 of the present utility model is a convenient installation scaffold. On the basis of embodiment 1, an indicator line 7 corresponding to the cross hole 111 is vertically painted on the outer wall of the first cover body 11 and the second cover body 21. The indicator line 7 corresponds to the cross hole 111. When the indicator lines 7 of the first cover body 11 and the second cover body 21 are collinear, it means that the rotating cross block 241 can be directly inserted into the cross hole 111, which is convenient for early confirmation and saves installation time.

[0028] Embodiment 4 of the utility model is a convenient installation scaffold. On the basis of embodiment 1, it also includes a plurality of transverse connecting parts, each of which includes two third connecting covers 5 and a transverse steel pipe 4. One end of the third connecting cover 5 is pre-welded and fixed to the vertical steel pipe 3, and one end is open. The head and tail ends of the transverse steel pipe 4 are respectively inserted into the openings of the two third connecting covers 5, and the third connecting cover 5 is movably inserted with a latch 6 that vertically penetrates the transverse steel pipe 4. The transverse steel pipe 4 is connected through the two third connecting covers 5, which is convenient for disassembly and assembly; the latch 6 can prevent the transverse steel pipe 4 from falling off from the third connecting cover 5, ensuring the structural stability of the scaffold. Similarly, the installation of all transverse steel pipes 4 does not require the use of additional tools, which effectively improves the installation efficiency of the scaffold.

[0029] Embodiment 5 of the present invention is a convenient installation scaffold. Based on embodiment 4, the first cover body 11, the second cover body 21 and the third connecting cover 5 are all made of alloy tool steel. Alloy tool steel has high hardness and good toughness, wear resistance and heat resistance.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
