[0022] By adopting the above technical solution, rotating the upper or lower turntable causes it to rotate synchronously with the connecting piece. During the rotation of the upper turntable, the locking rod abuts against the bottom wall of the sliding groove. As the upper and lower turntables rotate, the locking rod moves from the end with the larger distance between the bottom wall of the sliding groove and the fixed plate to the end with the smaller distance, causing the locking rod to move towards the plug-in joint. This allows the locking rod to be inserted into the plug-in hole of the plug-in joint, achieving quick installation of the diagonal tie rod and the circular disc buckle, as well as the crossbar and the circular disc buckle. Reverse rotation of the upper or lower turntable, under the action of the spring...

Then, the telescopic rod is pushed, causing it to move along the adjusting groove. The telescopic rod drives the limiting block to move, causing the limiting block to slide along the vertical groove. Due to the action of the spring, the locking rod and the limiting block continuously abut against each other, causing the locking rod and the limiting block to move synchronously. This allows the locking rod to separate from the plug-in connector, thus unlocking a single plug-in connector and subsequently unlocking a single diagonal tie rod.

[0033] By adopting the above technical solution, the chassis is placed on the ground so that it is in contact with the ground. Then, the lower threaded rod is adjusted to make it vertical. The lower threaded rod is then installed on the base. The installation height of the base is adjusted through the threaded connection between the lower threaded rod and the base. Then, the threaded section is installed on the base to realize the installation of the upright and the base. Finally, the lower adjusting seat is rotated so that it abuts against the base, realizing the installation of the adjustable base and the upright. The designed adjustable base, through the threaded connection between the lower threaded rod and the base, facilitates the adjustment of the height of the base, thereby facilitating the adjustment of the installation height of the upright and realizing the stable installation of the adjustable base and the upright.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The designed disc-lock scaffolding uses telescopic diagonal braces to facilitate the adjustment of the brace length, thereby keeping the diagonal brace installed between the two circular disc locks in a taut state, preventing the diagonal brace from swaying and improving the connection strength of the scaffolding support system;

[0036] 2. The designed disc-lock scaffolding uses a circular disc lock to facilitate the synchronous movement of multiple locking rods toward the insertion hole side of the plug-in joint. This allows the locking rods to move toward the insertion hole side of the plug-in joint. Simultaneously, under the action of springs, the locking rods are raised and lowered synchronously, enabling the locking rods to be inserted and separated from the plug-in joint at the same time. This allows for the rapid assembly and disassembly of the plug-in joint and the circular disc lock, improving the efficiency of scaffolding assembly and disassembly.

[0037] 3. The designed disc-lock scaffolding utilizes an adjustable sliding section of the telescopic rod. This sliding section moves the limiting tooth plate, causing it to separate from the limiting rack. The telescopic rod then moves along the adjusting groove, which in turn moves the limiting block, causing it to slide along the vertical groove. Due to the spring, the locking rod and the limiting block remain in contact, allowing them to move synchronously. This separation of the locking rod from the connector unlocks the individual connector, and consequently, unlocks the individual tie rod. The slidable limiting block along the vertical groove facilitates the unlocking of individual locking rods, enabling the individual unlocking of tie rods and facilitating the disassembly and replacement of the required tie rods.

[0058] The implementation principle of a disc-lock scaffolding according to an embodiment of this application is as follows: First, according to the installation position of the disc-lock scaffolding, four base plates 21 are placed on the ground so that the base plates 21 are in contact with the ground. Then, the lower threaded rod 22 is adjusted so that the lower threaded rod 22 is in a vertical state. Then, the lower threaded rod 22 is installed on the base 23. The installation height of the base 23 is adjusted through the threaded connection between the lower threaded rod 22 and the base 23. Then, the threaded section 113 is installed on the base 23 to realize the installation of the upright 11 and the base 23. Finally, the lower adjusting seat 24 is rotated to lower the adjustment. The joint 24 abuts against the base 23, and then the crossbar 12 is installed between two adjacent uprights 11 and connected to the circular disc buckle 13 located on the same plane to realize the connection between the uprights 11 and the crossbar 12. Then, the sleeve part 41 is adjusted to adjust the length of the diagonal tie rod 4 so that the length of the diagonal tie rod 4 is slightly larger than the distance between the two circular disc buckles 13 to be installed. Then, the diagonal tie rod 4 is installed on the two circular disc buckles 13 to be installed. The sleeve part 41 is adjusted, and the sleeve part 41 drives the installation part 42 to move closer to each other to realize the tension of the diagonal tie rod 4 between the two circular disc buckles 13.

[0059] When installing the tie rod 4, align the plug connector 422 with the buckle hole 1311 to be installed, and then insert the plug connector 422 into the buckle hole 1311. After all the plug connectors 422 are fully inserted into the buckle holes 1311, rotate the upper turntable 1341 or the lower turntable 1342. Under the action of the connecting piece 1343, the upper turntable 1341 and the lower turntable 1342 rotate synchronously. During the rotation of the upper turntable 1341, because the locking rod 132 abuts against the bottom wall of the sliding groove 1344, the locking rod 132 moves from the end with the larger distance between the bottom wall of the sliding groove 1344 and the fixed plate 131 to the end with the smaller distance between the bottom wall of the sliding groove 1344 and the fixed plate 131, causing the locking rod 132 to move towards... The movement of one side of the plug-in connector 422 causes the locking rod 132 to be inserted into the plug-in hole of the plug-in connector 422, thereby enabling the quick installation of the diagonal pull rod 4 and the circular disc buckle 13, as well as the horizontal bar 12 and the circular disc buckle 13. Reverse rotation of the upper turntable 1341 or the lower turntable 1342, under the action of the spring 133, causes the locking rod 132 to move from the end with the smaller distance between the bottom wall of the sliding groove 1344 and the fixed plate 131 to the end with the larger distance between the bottom wall of the sliding groove 1344 and the fixed plate 131. This causes the locking rod 132 to move away from the plug-in hole of the plug-in connector 422 until it disengages from the plug-in hole, thus enabling the quick disassembly of the diagonal pull rod 4 and the circular disc buckle 13, as well as the horizontal bar 12 and the circular disc buckle 13.

[0060] Pressing the sliding section 1371 causes the limiting tooth plate 138 to move away from the limiting toothed rack 139. The movement continues until the limiting tooth plate 138 separates from the limiting toothed rack 139. Then, the sliding section 1371 is pushed, causing the fixed section 1372 and the limiting tooth plate 138 to move synchronously. The fixed section 1372 causes the limiting block 136 to slide along the vertical groove 1361. Due to the action of the spring 133, the locking rod 132 and the limiting block 136 continue to abut against each other, causing the locking rod 132 and the limiting block 136 to move synchronously. This causes the locking rod 132 to separate from the plug connector 422, thereby unlocking the single plug connector 422 and thus unlocking the single diagonal pull rod 4.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
