[0040] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] Referring to Figures 1-6, a disc-lock scaffold includes an adjustable base 1, vertical uprights 2, connecting horizontal bars 3, supporting diagonal bars 4, and a quick-release structure 5. The adjustable base 1 supports the vertical uprights 2 and can be adjusted according to the ground level to ensure the overall levelness of the scaffold. The vertical uprights 2 are detachably connected to the adjustable base 1, facilitating the installation and removal of both. The connecting horizontal bars 3 are horizontally positioned between two vertical uprights 2, providing horizontal support between them and enhancing the stability of the scaffold. The supporting diagonal bars 4 are inclined... Located between two vertical uprights 2, it provides diagonal support between the vertical uprights 2 to enhance the overall rigidity and lateral force resistance of the scaffold. Through the support diagonal brace 4, multiple triangular structures can be formed on the scaffold, thereby further improving the overall stability of the scaffold. The quick-release structure 5 is located between the vertical upright 2 and the connecting horizontal bar 3, and between the vertical upright 2 and the support diagonal brace 4, which can realize the quick connection and disassembly between the vertical upright 2 and the connecting horizontal bar 3, and the support diagonal brace 4, thereby improving the convenience of scaffold installation and disassembly, and thus improving the efficiency of scaffold erection and dismantling.

[0042] In some embodiments, the adjustable base 1 includes a bearing plate 11, a threaded rod 12, a support column 13, and an internal threaded cylinder 14. The bearing plate 11 is located on the ground and serves as the basic support component for the entire scaffold. It can be made of a large area of ​​steel plate or other high-strength materials and can evenly transfer the load of the scaffold to the ground to achieve stable placement of the scaffold on the ground. The threaded rod 12 is vertically located on the outer wall of the top of the bearing plate 11 and can connect the bearing plate 11 and the support column 13. The support column 13 is coaxially located on the outer wall of the top of the threaded rod 12, and a vertical pole 2 is inserted into the top of the support column 13. The inner wall of the internal threaded cylinder 14 is provided with an internal thread that matches the threaded rod 12, and the height can be adjusted through the threaded engagement of the two. The top of the internally threaded cylinder 14 supports the vertical pole 2. The vertical pole 2 is stably supported by the cooperation of the supporting column 13 and the internally threaded cylinder 14. When the internally threaded cylinder 14 is rotated, it will move along the axial direction of the threaded rod 12 due to the threaded engagement between the internally threaded cylinder 14 and the threaded rod 12. This controls the rise or fall of the internally threaded cylinder 14 on the threaded rod 12, thereby adjusting the height of the vertical pole 2 and thus adjusting the overall height and level of the scaffold.

[0043] In some embodiments, the adjustable base 1 further includes a rotating handle 15, which is disposed on the top outer wall of the internal threaded cylinder 14, making it convenient for the operator to rotate the internal threaded cylinder 14, thereby improving the convenience of adjustment.

[0044] In some embodiments, the vertical pole 2 includes a pole body 21, a connecting disc 22, a plurality of first pin holes 23, and a plurality of second pin holes 24. The pole body 21 is detachably connected to the support column 13, which can be connected by plug-in or bolts, facilitating installation and disassembly in different construction scenarios. The connecting disc 22 is coaxially sleeved on the pole body 21 and can be fixed to the pole body 21 by welding or other secure connection methods to ensure the stability of the connection. The connecting disc 22 can connect the horizontal bar 3 and the support column 13. The diagonal brace 4 is connected to the upright body 21. Multiple first pin holes 23 are evenly spaced on the connecting disc 22. A quick-release structure 5 connects the first pin holes 23 to the connecting crossbar 3, enabling the connection between the upright body 21 and the connecting crossbar 3. Multiple second pin holes 24 are also evenly spaced on the connecting disc 22, with a first pin hole 23 between adjacent second pin holes 24. A quick-release structure 5 connects the second pin holes 24 to the supporting diagonal brace 4, enabling the connection between the upright body 21 and the supporting diagonal brace 4. Through the first pin holes 23 and the second pin holes 24, the connecting crossbar 3 and the supporting diagonal brace 4 can be easily connected to the vertical upright 2, forming a stable frame structure.

[0045] In some embodiments, the quick-release structure 5 includes an overlapping joint 51, an insertion interface 52, and a positioning component. The overlapping joint 51 is located at both ends of the connecting horizontal bar 3 and the supporting diagonal bar 4, and can overlap with the connecting disc 22 of the vertical pole 2. The insertion interface 52 is located on the side of the overlapping joint 51 near the connecting disc 22 and is inserted into the connecting disc 22 to limit the insertion depth of the overlapping joint 51, thereby achieving pre-positioning in the horizontal direction and facilitating subsequent installation. The positioning component is located on the overlapping joint 51 and is inserted into the first pin hole 23 and the second pin hole 24 to fix the relative position of the overlapping joint 51 and the connecting disc 22, thereby achieving a firm connection between the connecting horizontal bar 3, the supporting diagonal bar 4, and the vertical pole 2.

[0046] In some embodiments, the positioning assembly includes a positioning block 53, a lifting groove 54, a sliding groove 55, a sliding rod 56, an adjusting rod 57, and a positioning spring 58. The positioning block 53 is inserted into the first pin hole 23 and the second pin hole 24. When the positioning block 53 is inserted into the pin hole, the overlapping joint 51 can be fixed on the connecting disc 22. The lifting groove 54 is located on the top wall of the insertion interface 52, and the positioning block 53 can slide within the lifting groove 54. The lifting groove 54 provides space for the lifting and lowering of the positioning block 53. The sliding groove 55 is located at the top of the lifting groove 54 and extends through the top of the overlapping joint 51. The sliding rod 56 is slidably located within the sliding groove 55, and the bottom of the sliding rod 56 is connected to the positioning block 53. The sliding of the sliding rod 56 can drive the positioning block 53 in the lifting groove 54. The internal lifting mechanism features an adjusting rod 57 hinged to the lap joint 51 at its middle and one end hinged to the top of the sliding rod 56. The operator can control the sliding rod 56 by operating the other end of the adjusting rod 57, thereby raising and lowering the positioning block 53. This allows the positioning block 53 to be inserted into and removed from the first pin hole 23 and the second pin hole 24. A positioning spring 58 is located between the inner top wall of the lifting groove 54 and the positioning block 53. It provides a certain preload after the positioning block 53 is inserted into the pin hole, ensuring a tight fit between the positioning block 53 and the pin hole, preventing the positioning block 53 from loosening, and thus improving the reliability and stability of the connection. The positioning spring 58 is also sleeved on the sliding rod 56.

[0047] In some embodiments, the positioning spring 58 is sleeved on the sliding rod 56, and the stability of the positioning spring 58 when it is deformed under force can be improved by the constraint of the sliding rod 56.

[0048] When connecting the horizontal bar 3 or the supporting diagonal bar 4 to the vertical pole 2, first press the adjusting rod 57, causing the adjusting rod 57 to drive the sliding rod 56 to slide upward in the sliding groove 55. The positioning spring 58 is compressed, opening the insertion interface 52. Insert the insertion interface 52 into the connecting disc 22, and then release the adjusting rod 57. Under the restoring force of the positioning spring 58 and the gravity of the positioning block 53 itself, the positioning block 53 descends in the lifting groove 54 and inserts into the first pin hole 23 or the second pin hole 24. At the same time, the elastic energy of the positioning spring 58 is not fully released, generating a preload force. When disassembly is required, reverse the operation of the adjusting rod 57 to pull the positioning block 53 out of the first pin hole 23 or the second pin hole 24, and the connecting horizontal bar 3 or the supporting diagonal bar 4 can be easily disassembled.

[0049] In some embodiments, the bottom wall of the insertion interface 52 is provided with a limiting groove, which can be inserted and cooperate with the positioning block 53. Through the limiting groove, the movement of the bottom of the positioning block 53 in the horizontal direction can be constrained, thereby further improving the stability during connection.

[0050] In some embodiments, the lap joint 51 is hinged to the end of the support diagonal rod 4, so that the angle of the support diagonal rod 4 can be adjusted within a certain range to adapt to different construction needs.

[0051] The specific working principle is as follows:

[0052] When using the disc-lock scaffolding of this utility model, firstly, based on the ground conditions of the construction site, adjust the height of the adjustable base 1 through the threaded connection between the support column 13 and the internal threaded cylinder 14 to keep the scaffolding level. Then, install the vertical uprights 2 on the adjustable base 1 (this is prior art and will not be described in detail here), thus achieving a detachable connection between the vertical uprights 2 and the adjustable base 1.

[0053] Next, install the connecting crossbar 3, press the adjusting rod 57 to open the insertion interface 52 on the lap joint 51 at the end of the connecting crossbar 3, and adjust the position of the connecting crossbar 3 so that the insertion interface 52 is inserted into the corresponding first pin hole 23 on the connecting disc 22. Release the adjusting rod 57 so that the positioning block 53 is engaged with the first pin hole 23, thereby achieving the connection and fixation between the connecting crossbar 3 and the vertical pole 2. After installing the connecting crossbar 3, similarly, install the supporting diagonal brace 4 at the set position of the vertical pole 2. After the entire assembly is completed, install the footboard, hanging net, and other structures to achieve the fixed installation of the scaffolding.

[0054] When disassembly is required, simply operate the directional controls to quickly disassemble the scaffolding.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
