[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6In this embodiment of the invention, the quick-connect disc-lock scaffolding includes several uprights 1 and several horizontal bars 11. Several rotating cylinders 2 are provided on the side walls of the uprights 1. Connecting discs 5 are horizontally fixedly connected to the side walls of the rotating cylinders 2. Eight first grooves 4 are formed in a circular array on both the upper and lower surfaces of the connecting discs 5. The first grooves 4 on the upper surface of the connecting discs 5 and the first grooves 4 on the lower surface of the connecting discs 5 are vertically aligned. Fixing blocks 12 are fixedly connected to both ends of each horizontal bar 11. The fixing blocks 12 are located at... A limiting block 13 that works with the first groove 4 is horizontally fixed to one end of the crossbar 11. The distance between the two limiting blocks 13 on the same fixed block 12 is the same as the height of the connecting plate 5. The first groove 4 and the limiting block 13 are provided with a connecting mechanism for quickly engaging the first groove 4 and the limiting block 13. A tightening mechanism is provided between the fixed block 12 and the connecting plate 5 for firmly connecting the crossbar 11 and the connecting plate 5. A rotating mechanism is provided between the upright 1 and the rotating cylinder 2 to facilitate adjusting the position of the connecting plate 5.

[0029] The connecting mechanism includes several sliders 20. Several right-angled triangular blocks 7 are fixedly connected to the bottom of the first groove 4. The inclined surface of the first right-angled triangular blocks 7 faces away from the rotating cylinder 2. Several second grooves 15 are formed at one end of the limiting block 13 near the first groove 4. The sliders 20 are always slidably connected to the inner wall of the second grooves 15. A second right-angled triangular block 21, which cooperates with the first right-angled triangular blocks 7, is fixedly connected at one end of the slider 20 near the first groove 4. The inclined surface of the second right-angled triangular block 21 faces away from the fixing block 12. The second grooves 15 can completely accommodate the sliders 20 and the second right-angled triangular blocks 21. The second right-angled triangular blocks 21 have the same length as the first right-angled triangular blocks 7. A sliding rod 19 is fixedly connected to one end of the slider 20 away from the second right-angled triangular block 21. The end of the sliding rod 19 away from the slider 20 slides through the limiting block 13 and is fixedly connected to a fixing plate 17. Several tension springs 18 are provided between the fixing plate 17 and the limiting block 13 for pulling the fixing plate 17 closer to the limiting block 13. The two ends of the tension springs 18 are fixedly connected to the fixing plate 17 and the limiting block 13 respectively. A handle 16 is fixedly connected to one end of the fixing plate 17 away from the limiting block 13 to facilitate the operator to pull the fixing plate 17 away from the limiting block 13. An elastic rubber baffle 14 is fixedly connected to the side wall of the fixing plate 17 to prevent debris from entering between the fixing plate 17 and the limiting block 13. The end of the elastic rubber baffle 14 away from the fixing plate 17 is fixedly connected to the limiting block 13.

[0030] During connection, the operator moves the handle 16 away from the limit block 13. The handle 16 moves the fixing plate 17, the slide bar 19, the slider 20, and the second right-angled triangle block 21, and stretches the tension spring 18 and the elastic rubber baffle 14, so that the second right-angled triangle block 21 is stored inside the second groove 15.

[0031] Then, the staff put the two limiting blocks 13 on the upper and lower surfaces of the connecting plate 5 and aligned the limiting blocks 13 with the first groove 4. Then, the handle 16 was released. Under the action of the elastic force, the tension spring 18 pulled the fixing plate 17, the slide rod 19, the slider 20, and the second right-angled triangle block 21 to move, so that the second right-angled triangle block 21 and the first right-angled triangle block 7 were engaged with each other.

[0032] When the limiting block 13 is adjusted toward the upright 1, the inclined surface of the second right-angled triangle block 21 slides against the inclined surface of the first right-angled triangle block 7, which facilitates the movement of the limiting block 13 toward the upright 1. When the limiting block 13 is adjusted away from the upright 1, the operator needs to move the handle 16 away from the limiting block 13 to store the second right-angled triangle block 21 inside the second groove 15.

[0033] The clamping mechanism includes a second rotating block 25. A second rotating groove 24 is provided at the end of the fixed block 12 away from the crossbar 11. The second rotating block 25 is rotatably connected to the inner wall of the second rotating groove 24. A fourth rotating block 26 is fixedly connected to the end of the second rotating block 25 away from the second rotating groove 24. Several through holes 27 are arranged in a circular array on the side wall of the fourth rotating block 26 to facilitate the operator's use of a rod to rotate the fourth rotating block 26. A fourth rotating block 26 is fixedly connected in a circular array at the end of the fourth rotating block 26 away from the fixed block 12. Several second support blocks 28 are provided, one end of which is fixedly connected to a second guide inclined block 29. Several first support blocks 22 that cooperate with the second support blocks 28 are fixedly connected in a circular array on the side wall of the connecting disc 5 at the end of the first groove 4 away from the upright 1. One end of the first support block 22 is fixedly connected to a first guide inclined block 23 that cooperates with the second guide inclined block 29. The first support blocks 22 and the second support blocks 28 are staggered, and the inclined surfaces of the second guide inclined block 29 and the first guide inclined block 23 are in contact with each other.

[0034] After the limiting block 13 is fixedly connected to the first groove 4, the worker inserts the rod into the through hole 27 and then rotates the fourth rotating block 26. The fourth rotating block 26 drives the second support block 28 and the second guide inclined block 29 to rotate. Under the guidance of the inclined surface, the end face of the first support block 22 is tightly attached to the end face of the second support block 28. At the same time, the second support block 28 pushes the fourth rotating block 26, the fixing block 12, the crossbar 11, the limiting block 13, the slider 20, and the second right-angled triangular block 21 away from the upright 1. The vertical surface of the second right-angled triangular block 21 is tightly pressed against the vertical surface of the first right-angled triangular block 7, thereby fastening the crossbar 11, the fixing block 12, the limiting block 13, and the connecting plate 5 together.

[0035] The rotating mechanism includes a first rotating block 6, which is fixedly connected to the side wall of the upright 1 inside the rotating cylinder 2. The inner wall of the rotating cylinder 2 is provided with a first rotating groove 3 that cooperates with the first rotating block 6. The first rotating block 6 is rotatably connected to the inner wall of the first rotating groove 3. An internally threaded fixing cylinder 10 is fixedly connected to the side wall of the rotating cylinder 2. The internally threaded fixing cylinder 10 is perpendicular to the rotating cylinder 2. A threaded rod 8 is rotatably connected to the inner wall of the internally threaded fixing cylinder 10 by a thread. A third rotating block 9 is fixedly connected to the end of the threaded rod 8 away from the upright 1. The end of the threaded rod 8 away from the third rotating block 9 is pressed tightly against the side wall of the upright 1.

[0036] If the position of the first groove 4 on the connecting plate 5 is deviated, the operator rotates the third rotating block 9, which drives the threaded rod 8 to rotate. Under the action of the thread, the threaded rod 8 moves away from the upright 1, releasing the fixed connection between the upright 1 and the rotating cylinder 2. Then, the operator rotates the connecting plate 5 to adjust the position of the first groove 4 on the connecting plate 5. After the adjustment is completed, the operator rotates the third rotating block 9, which drives the threaded rod 8 to rotate. Under the action of the thread, the threaded rod 8 presses tightly against the side wall of the upright 1, fixing the rotating cylinder 2 to the side wall of the upright 1.

[0037] The working principle of quick-connect disc-lock scaffolding:

[0038] During connection, the operator moves the handle 16 away from the limit block 13. The handle 16 moves the fixing plate 17, the slide bar 19, the slider 20, and the second right-angled triangle block 21, and stretches the tension spring 18 and the elastic rubber baffle 14, so that the second right-angled triangle block 21 is stored inside the second groove 15.

[0039] Then, the staff put the two limiting blocks 13 on the upper and lower surfaces of the connecting plate 5 and aligned the limiting blocks 13 with the first groove 4. Then, the handle 16 was released. Under the action of the elastic force, the tension spring 18 pulled the fixing plate 17, the slide rod 19, the slider 20, and the second right-angled triangle block 21 to move, so that the second right-angled triangle block 21 and the first right-angled triangle block 7 were engaged with each other.

[0040] When the limiting block 13 is adjusted toward the upright 1, the inclined surface of the second right-angled triangle block 21 slides against the inclined surface of the first right-angled triangle block 7, which facilitates the movement of the limiting block 13 toward the upright 1. When the limiting block 13 is adjusted away from the upright 1, the operator needs to move the handle 16 away from the limiting block 13 to store the second right-angled triangle block 21 inside the second groove 15.

[0041] If the position of the first groove 4 on the connecting plate 5 is deviated, the operator rotates the third rotating block 9, which drives the threaded rod 8 to rotate. Under the action of the thread, the threaded rod 8 moves away from the upright 1, releasing the fixed connection between the upright 1 and the rotating cylinder 2. Then, the operator rotates the connecting plate 5 to adjust the position of the first groove 4 on the connecting plate 5. After the adjustment is completed, the operator rotates the third rotating block 9, which drives the threaded rod 8 to rotate. Under the action of the thread, the threaded rod 8 presses tightly against the side wall of the upright 1, fixing the rotating cylinder 2 to the side wall of the upright 1.

[0042] After the limiting block 13 is fixedly connected to the first groove 4, the worker inserts the rod into the through hole 27 and then rotates the fourth rotating block 26. The fourth rotating block 26 drives the second support block 28 and the second guide inclined block 29 to rotate. Under the guidance of the inclined surface, the end face of the first support block 22 is tightly attached to the end face of the second support block 28. At the same time, the second support block 28 pushes the fourth rotating block 26, the fixing block 12, the crossbar 11, the limiting block 13, the slider 20, and the second right-angled triangular block 21 away from the upright 1. The vertical surface of the second right-angled triangular block 21 is tightly pressed against the vertical surface of the first right-angled triangular block 7, thereby fastening the crossbar 11, the fixing block 12, the limiting block 13, and the connecting plate 5 together.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
