[0025] (III) Beneficial Effects

[0026] Compared with the prior art, this utility model provides an easily adjustable scaffolding with the following features:

[0027] Beneficial effects:

[0028] 1. This easily adjustable scaffolding, when in use, involves the worker standing above the load-bearing plate. The worker grips the handrail and exerts force upwards and to the left, moving the handrail upwards and to the left. This movement moves the second fixed seat upwards and to the left, which in turn moves the connecting column upwards and to the left. The connecting column rotates at one end inside the second fixed seat, while the limiting cylinder rotates upwards and to the left, causing the connecting column to rotate at one end inside the first fixed seat. The connecting column moves until it is flush with the inner left wall of the first fixed seat and cannot move further. Simultaneously, the top right side of the connecting column aligns with the right side of the second fixed seat. The inner walls are fitted together to secure the connecting column, preventing movement. Simultaneously, the handle moves upwards and to the left, causing its fixing ring to move. This movement of the fixing ring, in turn, moves the safety chain. The handle's upward and to the left also moves the handle housing, which in turn moves the handle itself. This movement of the handle, in turn, moves the spring, which in turn moves the second connecting block. This second connecting block, in turn, moves the locking block. Simultaneously, the connecting column moves upwards and to the left, causing the fixing block to move upwards and to the left. When the left arc surface of the locking block contacts the right arc surface of the fixing block, the movement continues. The right arc surface of the fixed block presses the snap-fit ​​block upward, causing it to move upward. This upward movement of the snap-fit ​​block moves the second connecting block upward, which in turn moves the handle upward. The upward movement of the handle compresses the spring at its top against the top of the handle groove. When the connecting post is fixed, the snap-fit ​​block aligns with the insertion interface. The spring force pulls the handle downward, causing it to insert into the insertion interface. After raising and fixing the two handles, the connecting buckles on the two rear safety chains are hooked onto the fixing ring on the front handle. Then, the two reverse motors are started. The output of the reversing motor rotates, driving two worm gears to rotate. The two worm gears then drive two turbines to rotate, which in turn drive two threaded rods to rotate upwards. This upward rotation of the threaded rods causes the first connecting block to move upwards. The upward movement of the first connecting block causes four limiting cylinders to slide upwards on the outer surface of the fixed column. The four limiting cylinders limit the movement of the equipment, preventing tilting. The upward movement of the first connecting block also causes the load-bearing plate to move upwards, allowing workers to reach the desired position. The protective device prevents workers from falling while working on the scaffold, reducing the danger of worker accidents.

[0029] 2. This easily adjustable scaffolding, when finished using the equipment, activates two reverse motors. The outputs of the two reverse motors rotate in opposite directions, driving two worm gears to rotate in opposite directions. The two worm gears rotate in opposite directions, driving two worm wheels to rotate in opposite directions. The two worm wheels rotate in opposite directions, driving two threaded rods to rotate downwards. The downward rotation of the two threaded rods resets the scaffolding lifting device. The worker grasps the connecting buckle and releases it from the inside of the fixing ring, removing the side protections. The worker places their palm on the upper surface of the handle, grips the handle with their fingers, and applies force towards the palm to move the handle upwards. The upward movement of the handle compresses the spring, causing the handle to move upwards, causing the locking block to move upwards and disengage from the inner wall of the insertion interface. The worker applies pressure to the lower right of the handle to release the fixing of the protective device, causing the protective device to reset and disengage. This makes the protective devices all movable, eliminating the need for workers to lift necessary items to the highest point of the protective device, reducing the worker's workload, and making it more convenient for workers to enter the scaffolding.

Detailed Implementation

[0038] 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.

[0039] Please see Figure 1-7 This utility model provides a technical solution: an easily adjustable scaffold, wherein fixed columns 2 are fixedly installed at the four corners of the top of the base 1, and limiting cylinders 5 are slidably fitted on the outer surfaces of the four fixed columns 2. First connecting blocks 6 are fixedly installed at the top of the opposite sides of the two limiting cylinders 5. Load-bearing plates 7 are fixedly installed on the top of the two first connecting blocks 6. Connecting plates 8 are fixedly installed at the middle of the front and rear ends of the load-bearing plates 7. Protective devices are provided on the two connecting plates 8. Threaded fixed columns 3 are fixedly installed at the middle of the two sides of the base 1 corresponding to the fixed columns 2. Lifting devices are provided on the two threaded fixed columns 3. Fixed plates 4 are fixedly installed on the outer surfaces of the two threaded fixed columns 3 near the top. Power devices are provided on the fixed plates 4. Universal wheels 9 are fixedly installed at the bottom of the base 1.

[0040] Furthermore, the protective device includes first fixing seats 14. First fixing seats 14 are equidistantly fixedly installed at the top positions of the two connecting plates 8. Each of the eight first fixing seats 14 has a connecting post 15 inside. The eight connecting posts 15 are rotatably connected to the eight first fixing seats 14 by rivets. Each of the eight connecting posts 15 has a second fixing seat 16 at the end away from the eight first fixing seats 14. The eight second fixing seats 16 are rotatably connected to one end of each of the eight connecting posts 15 by the same rivets. Two handles 17 are fixedly installed at the end of each of the eight second fixing seats 16 away from the eight connecting posts 15. Fixing rings 18 are fixedly installed on both sides of each of the two handles 17. Safety chains 19 are fixedly connected to the two fixing rings 18 on each of the handles 17. Connecting buckles 20 are fixedly connected to one end of each of the two safety chains 19 away from the rear end of the two fixing rings 18. The two connecting buckles 20 are movably fitted onto the front end. On the two fixed rings 18, the bottom right side of the two handles 17 are fixedly installed with handle housings 24. The handle housings 24 are equipped with fixing devices. When the worker stands above the load-bearing plate 7, he holds the handles 17 and exerts force to the upper left. The worker's grip on the handles 17 and exerts force to the upper left moves the handles 17 to the upper left. The movement of the handles 17 to the upper left moves the second fixed seat 16 to the upper left. The movement of the second fixed seat 16 to the upper left moves the connecting column 15 to the upper left. The movement of the connecting column 15 to the upper left causes one end of the connecting column 15 to rotate inside the second fixed seat 16. The movement of the limiting cylinder 5 to the upper left causes one end of the connecting column 15 to rotate inside the first fixed seat 14. The connecting column 15 moves until it is flush with the inner left wall of the first fixed seat 14 and cannot move. At the same time, the top right side of the connecting column 15 is attached to the inner right side wall of the second fixed seat 16 for fixation, preventing the connecting column 15 from moving.

[0041] Furthermore, the lifting device includes threaded rods 11. The two threaded fixing columns 3 are both internally threaded with threaded rods 11. The tops of the two threaded rods 11 are rotatably connected to the middle positions of the two first connecting blocks 6. The tops of the two threaded fixing columns 3 are rotatably connected with turbines 10. The center positions of the two turbines 10 are threadedly connected to the two threaded rods 11. The rotation of the two turbines 10 drives the two threaded rods 11 to rotate upwards. The upward rotation of the two threaded rods 11 drives the first connecting blocks 6 to move upwards. The upward movement of the two first connecting blocks 6 drives the four limiting cylinders 5 to slide upwards on the outer surface of the fixing column 2. The four limiting cylinders 5 limit the device to prevent tilting forward and backward. The upward movement of the first connecting blocks 6 drives the load-bearing plate 7 to move upwards.

[0042] Furthermore, the power unit includes a worm gear 13, and a worm gear 13 is provided at the rear end of each of the two turbines 10. The two worm gears 13 are meshed with the two turbines 10. Two reverse motors 12 are fixedly installed on the upper surface of the fixing plate 4. The output ends of the two reverse motors 12 are fixedly connected to the two worm gears 13. When the two reverse motors 12 are started, the output ends of the two reverse motors 12 rotate, driving the two worm gears 13 to rotate. The rotation of the two worm gears 13 drives the two turbines 10 to rotate.

[0043] Furthermore, the fixing device includes a grip groove 25. Grip grooves 25 are formed inside the two grip housings 24. Grips 26 are slidably disposed inside each of the two grip grooves 25. Springs 27 are fixedly installed at equal intervals on the top of each of the two grips 26. The ends of the three springs 27 away from the grips 26 are fixedly installed on the inner wall of the grip groove 25. Second connecting blocks 28 are fixedly installed at the bottom of the ends of the two grips 26 near the connecting post 15. A snap-fit ​​block 21 is fixedly installed in the middle of the ends of the two second connecting blocks 28 away from the two grips 26. The ends of the two second connecting blocks 28 away from the first fixing seat 14 are located near the bottom. The handle 17 is fixedly installed with two grip slots 25, each with a corresponding groove. The two grooves are slidably connected to the two grips 29. On the right side of each handle 17, the first connecting post 15 near the second fixing seat 16 has a fixing block 22 fixedly fitted onto its outer surface. The two fixing blocks 22 have insertion interfaces 23 corresponding to the two snap-fit ​​blocks 21. The two insertion interfaces 23 are compatible with the two snap-fit ​​blocks 21. Simultaneously, when the handle 17 moves to the upper left, its fixing ring 18 moves accordingly, causing the safety chain 19 to move as well. At the same time, the upper left movement of the handle 17 also moves the handle housing 24. As the grip housing 24 moves, it drives the grip 26 to move as well. The grip 26 then drives the spring 27, which in turn drives the second connecting block 28. The second connecting block 28 then drives the second connecting block 29 to move as well. The second connecting block 28 then drives the locking block 21 to move as well. Simultaneously, the connecting post 15 moves to the upper left, causing the fixing block 22 to move to the upper left. When the left arc surface of the locking block 21 contacts the right arc surface of the fixing block 22, the block continues to move, causing the right arc surface of the fixing block 22 to press the locking block 21 upward. The upward movement of the locking block 21 then drives the second connecting post 26 to move upward. Block 28 moves upward, and the second connecting block 28 moves upward, causing 29 to move upward. The second connecting block 28 moves upward, causing the handle 26 to move upward. The handle 26 moves upward, pressing the spring 27 at its top against the top of the inner wall of the handle groove 25. When the connecting post 15 is fixed, the snap-fit ​​block 21 corresponds to the insertion interface 23. The spring 27 stretches downward, causing the handle 26 to move downward, so that the snap-fit ​​block 21 is inserted into the insertion interface 23. After the two handles 17 are raised and fixed, the connecting buckles 20 on the two safety chains 19 at the rear end are picked up and hooked onto the fixing ring 18 on the front handle 17.

[0044] Working principle: In use, the worker stands above the load-bearing plate 7 and grips the handle 17, pushing it upwards and to the left. This movement causes the handle 17 to move upwards and to the left, which in turn moves the second fixed seat 16 upwards and to the left. This movement of the second fixed seat 16 in turn moves the connecting column 15 upwards and to the left, causing one end of the connecting column 15 to rotate inside the second fixed seat 16. Simultaneously, the limiting cylinder 5 moves upwards and to the left, causing one end of the connecting column 15 to rotate inside the first fixed seat 14. The connecting column 15 moves until it is flush with the inner left wall of the first fixed seat 14 and cannot move further. At the same time, the top right side of the connecting column 15 is pressed against the inner right wall of the second fixed seat 16 for fixation, preventing further movement. As the connecting post 15 moves, the handle 17 moves to the upper left, causing its fixing ring 18 to move accordingly. The moving of the fixing ring 18 then moves the safety chain 19. Simultaneously, the upper left movement of the handle 17 causes the grip housing 24 to move, which in turn moves the grip 26. The grip 26 then moves the spring 27, which in turn moves the second connecting block 28. The second connecting block 28 then moves the second connecting block 29, which in turn moves the locking block 21. Simultaneously, the upper left movement of the connecting post 15 causes the fixing block 22 to move to the upper left. When the left arc surface of the locking block 21 contacts the right arc surface of the fixing block 22, the movement continues, causing the right arc surface of the fixing block 22 to... The upward pressing of the locking block 21 causes it to move upward, which in turn moves the second connecting block 28 upward. The upward movement of the second connecting block 28 then moves the handle 26 upward, causing it to press the spring 27 at its top against the top of the handle groove 25. When the connecting post 15 is fixed, the locking block 21 corresponds to the insertion interface 23. The spring 27 pulls the handle 26 downward, causing it to insert into the insertion interface 23. After the two handles 17 are raised and fixed, the connecting buckles 20 on the two rear safety chains 19 are picked up and hooked onto the fixing rings 18 on the front handle 17. Then, the two reverse motors 12 are started. The output of the reversing motor 12 rotates, driving two worm gears 13 to rotate. The worm gears 13 then drive two worm wheels 10 to rotate, which in turn drive two threaded rods 11 to rotate upwards. This upward rotation of the threaded rods 11 moves the first connecting block 6 upwards. The upward movement of the first connecting block 6 causes four limiting cylinders 5 to slide upwards on the outer surface of the fixed column 2. The four limiting cylinders 5 limit the movement of the equipment, preventing tilting. The upward movement of the first connecting block 6 also moves the load-bearing plate 7 upwards, allowing workers to reach the desired position. The safety device prevents workers from falling while working on the scaffold, reducing the danger during operation. When finishing using the equipment, the two reversing motors 12 are restarted.The outputs of the two reverse motors 12 rotate in opposite directions, driving the two worm gears 13 to rotate in opposite directions. The two worm gears 13 rotate in opposite directions, driving the two turbines 10 to rotate in opposite directions. The two turbines 10 rotate in opposite directions, driving the two threaded rods 11 to rotate downwards. The downward rotation of the two threaded rods 11 resets the scaffolding lifting device. The worker grasps the connecting buckle 20 and releases it from the inside of the fixing ring 18, removing the side protections. The worker places their palm on the upper surface of the handrail 17, grips the handle 26 with their fingers, and applies force towards their palm, causing the handle 26 to move upwards. The upward movement of the handle 26 compresses the spring 27, causing it to move upwards. The upward movement of the handle 26 drives the locking block 21 to move upwards, causing the locking block 21 to disengage from the inner wall of the insertion interface 23. The worker then moves towards the handrail... 17. Applying pressure to the lower right releases the fixing of the protective device, causing it to reset and become movable. This eliminates the need for workers to lift items to the highest point of the protective device, reducing their workload and making it easier for them to enter the scaffold. This solves the problem of workers being at risk of falling when working on scaffolds without proper safety measures, which was a common issue when most scaffolds lacked protective devices. It also addresses the problem of workers having to lift items to the top of the protective device and place them inside the scaffold when using fixed protective devices, increasing their workload and making it inconvenient for them to enter the equipment.
