[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1-3 This utility model provides a construction scaffold, including a support plate body 1. Four first support legs 2 are rotatably connected to the bottom surface of the support plate body 1, and the four first support legs 2 are correspondingly arranged at the four corners of the support plate body 1. A retraction / extension assembly is installed between two first support legs 2 located on the same side. A sliding plate 3 is slidably connected to the support plate body 1. Second support legs 4 are rotatably connected to the two sides of the end of the sliding plate 3 away from the support plate body 1, and a limit assembly is installed between the second support legs 4 and the sliding plate 3. The bottom of the second support legs 4 is flush with the bottom of the first support legs 2. By sliding the sliding plate 3 on the support plate body 1, the sliding plate 3 can slide on the support plate body 1, thereby increasing the support area of ​​the scaffold, thus reducing the number of times workers need to move the scaffold during construction and increasing work efficiency. This utility model can adjust the state of the first support legs 2 and the second support legs 4 by controlling the retraction / extension assembly and the limit assembly, making them easy to retract and extend.

[0020] The scheme is further optimized. The retractable component includes a receiving groove 5 opened on the bottom surface of the support plate body 1. Two sliding blocks 6 are slidably connected in the receiving groove 5. The two sliding blocks 6 are correspondingly set with two first support legs 2 located on the same side. A support rod 7 is rotatably connected between the bottom surface of the sliding block 6 and the middle of the corresponding first support leg 2. A control component is provided in the support plate body 1 to drive the two sliding blocks 6 to move towards or away from each other.

[0021] The scheme is further optimized. The control component includes a bidirectional threaded rod 8 located within the receiving groove 5 and rotatably connected to the inner wall of the receiving groove 5. The threads on both sides of the bidirectional threaded rod 8 have opposite directions. The bidirectional threaded rod 8 passes through two sliding blocks 6 and is threadedly connected to the sliding blocks 6. The two sliding blocks 6 are located on both sides of the bidirectional threaded rod 8. One end of the bidirectional threaded rod 8 passes through the side wall of the receiving groove 5 and is fixedly connected to a rotating handle 9, which is located on the side of the support plate body 1. By rotating the handle 9, the two sliding blocks 6 are driven to move towards or away from each other, thereby adjusting the distance between the two sliding blocks 6. This, in turn, pushes or pulls the first support leg 2 to rotate via the support rod 7, thereby controlling the extension and retraction of the first support leg 2.

[0022] The scheme is further optimized. The limiting component includes a limiting plate 10 that is rotatably connected to the side wall of the sliding plate 3. The limiting plate 10 is correspondingly set with the second support leg 4. A limiting post 11 is fixedly connected to the second support leg 4. A limiting groove 12 is opened on the limiting plate 10 corresponding to the limiting post 11. The limiting post 11 is located in the limiting groove 12. A sliding groove 13 is opened in the limiting plate 10. The sliding groove 13 is connected to the limiting groove 12. A limiting block 14 is slidably connected in the sliding groove 13. One end of the limiting block 14 is located in the limiting groove 12 and is in contact with the limiting post 11. The other end of the limiting block 14 is located in the sliding groove 13 and is fixedly connected to the bottom wall of the sliding groove 13 with a compression spring 15. A toggle post 16 is fixedly connected to the side of the limiting block 14. A through groove 17 for the toggle post 16 to move is opened on the bottom side of the limiting plate 10. The through groove 17 is connected to the sliding groove 13. By moving the limiting post 11 into the limiting groove 12, the limiting block 14 limits the limiting post 11, thereby limiting the second support leg 4 and stabilizing it in the working state.

[0023] To further optimize the design, a mounting hole 18 is provided on the top surface of the sliding plate 3 near the support plate body 1. Threaded holes 19, which are adapted to the mounting hole 18, are provided on both sides of the top surface of the support plate body 1. The mounting hole 18 and any one of the threaded holes 19 are fixedly connected by bolts. By engaging the mounting hole 18 with the two threaded holes 19, bolts can be used to fix the plate in place, ensuring it remains stable in either the working or retracted state.

[0024] In a further optimized design, the limiting block 14 is a trapezoidal block, with its inclined surface located on the side away from the limiting post 11. This allows the limiting post 11 to directly press against the limiting block 14 when the limiting plate 10 limits the second support leg 4, causing the limiting block 14 to retract and facilitating direct engagement with the limiting plate 10. This allows the limiting post 11 to move to the inside of the limiting groove 12.

[0025] In a further optimized design, a roller 20 is rotatably connected to the bottom of the second support leg 4, with the bottom of the roller 20 flush with the bottom of the first support leg 2. The flush alignment of the roller 20 with the first support leg 2 facilitates the sliding of the sliding plate 3 during support, thus simplifying the installation of the construction frame.

[0026] The working process of this utility model is as follows: In use, rotating the handle 9 drives the bidirectional threaded rod 8 to rotate, which in turn drives the two sliding blocks 6 to move in opposite directions. This causes the two first support legs 2 to stand upright via the support rod 7, supporting the support plate body 1. Then, the sliding plate 3 is pushed, with the mounting holes on the sliding plate 3 corresponding to the threaded holes 19, and thus fixed with bolts. Next, rotating the limiting plate 10 causes the limiting groove 12 on the limiting plate 10 to move to the limiting post 11, where it is limited by the limiting block 14, thereby stabilizing the second support leg 4 in a vertical position. This increases the support area of ​​the construction frame, facilitating construction. When it needs to be retracted, simply pull the actuating column 16 to release the limiting block 14 from limiting the limiting post 11, and rotate the limiting plate 10 to retract the limiting plate 10 and the second support leg 4. Then turn the handle 9, which will cause the two sliding blocks 6 to move towards each other. This will then pull the two first support legs 2 up through the support rod 7. Then remove the bolts and push the sliding plate 3 so that the mounting hole 19 aligns with another threaded hole 19. By using the bolts to limit the movement, the construction frame can be retracted for easy storage.
