[0024] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a construction scaffolding, comprising: a main load-bearing block 1, with limiting frames 2 fixedly connected to both sides of the main load-bearing block 1. A connecting side plate 3 is slidably sleeved on one side of the limiting frame 2, and an adjusting handwheel 4 is arranged on one side of the connecting side plate 3. The main load-bearing block 1 facilitates the operator to stand on it for construction operations on the main body position. The limiting frame 2 limits the connecting side plate 3 to facilitate its sliding. The adjusting handwheel 4 facilitates adjusting the extending distance of the connecting side plate 3. Connecting seats 10 are fixedly connected to both sides of the main load-bearing block 1, the limiting frame 2, and the connecting side plate 3. An adjusting rod 11 is sleeved in the connecting seat 10 and is threadedly connected to the adjusting rod 11. The bottom end of the adjusting rod 11 is fixedly connected to a grounding block 12. The connecting seat 10 is fixedly installed on the main load-bearing block 1, the limiting frame 2, and the connecting side plate 3. The connecting seat 10 is used to limit the adjusting rod 11. By rotating the adjusting rod 11, the grounding block 12 is driven, thus facilitating the support of the entire device. Trampling grooves 13 are opened on both sides of the main load-bearing block 1. Universal wheels 14 are fixedly connected to the lower surfaces of the main load-bearing block 1, the limiting frame 2, and the connecting side plate 3. The trampling grooves 13 opened on both sides of the main load-bearing block 1 facilitate the operator to climb onto the main load-bearing block 1. Universal wheels 14 are fixedly installed at the bottoms of the main load-bearing block 1, the limiting frame 2, and the connecting side plate 3, thus facilitating the movement of the entire device. A placing sleeve 16 is fixedly connected to one side of the connecting side plate 3. The adjusting handwheel 4 is slidably sleeved in the placing sleeve 16. A cross column 17 is fixedly connected to the bottom of the adjusting handwheel 4. The placing sleeve 16 is fixedly installed on one side of the connecting side plate 3 for placing the adjusting handwheel 4. When in use, the adjusting handwheel 4 is taken out. When the use is completed, the adjusting handwheel 4 can be sleeved in the placing sleeve 16.

[0025] Through the universal wheels 14 fixedly installed at the bottoms of the main load-bearing block 1, the limiting frame 2, and the connecting side plate 3, the entire device can be moved to the indoor construction area. Then, the operator rotates the adjusting rods 11 installed on both sides of the main load-bearing block 1 and the limiting frame 2. Since the adjusting rod 11 is threadedly connected to the connecting seat 10, the adjusting rod 11 drives the grounding block 12 to move downward until it contacts the ground. The grounding block 12 is made of an anti-slip pad, thus increasing the stability of the support for the entire device. After the main load-bearing block 1 is stable, the operator climbs onto the main load-bearing block 1 through the trampling grooves 13, so that the carpenter can perform high-altitude construction with the help of the elevation of the scaffolding.

[0026] A support box 5 is fixedly installed in the limiting frame 2. A worm gear 6 is installed on one side of the support box 5. A rotating shaft 7 is sleeved in the worm gear 6. Gears 8 are installed on both sides of the rotating shaft 7. A tooth column 9 is meshed with the upper side of the gear 8. One end of the tooth column 9 is fixedly connected to the inner wall of the connecting side plate 3. The support box 5 is fixedly installed inside the limiting frame 2. By driving the rotating shaft 7 to rotate through the worm gear 6, the rotating shaft 7 drives the gear 8 to rotate. The gear 8 is in meshing transmission with the tooth column 9, so that the tooth column 9 drives the connecting side plate 3 to slide outward in the limiting frame 2.

[0027] On one side of the worm gear 6, there is a worm 18 meshed with it. The lower end of the worm 18 is rotatably sleeved in the support box 5. The upper end of the worm 18 penetrates through the connecting side plate 3 and is rotatably sleeved in the limit frame 2. On the upper surface of the worm 18, there is a cross groove 19, and there is a sliding connection between the cross groove 19 and the cross column 17. There is a meshing transmission between the worm gear 6 and the worm 18. The lower end of the worm 18 is rotatably installed in the support box 5, and the upper end of the worm 18 is rotatably sleeved in the limit frame 2. Through the cross groove 19 opened on the upper surface of the worm 18, it is convenient to drive the worm 18 to rotate by the adjusting handwheel 4 through the cross column 17. On the upper surface of the connecting side plate 3, there is a limit groove 20, and the limit groove 20 is slidably connected with the upper end of the worm 18. Both ends of the rotating shaft 7 are rotatably sleeved in the support box 5. The gear 8 is fixedly sleeved on the rotating shaft 7. One side of the tooth column 9 is slidably sleeved in the sliding hole 15, and the other side of the tooth column 9 is slidably sleeved in the support box 5. There is a sliding connection between the limit groove 20 opened on the upper surface of the connecting side plate 3 and the upper end of the worm 18, so as to facilitate the limitation of the connecting side plate 3 during the sliding process. The support box 5 limits and supports both ends of the rotating shaft 7, so as to facilitate its rotation. The sliding hole 15 limits one side of the tooth column 9, and the support box 5 limits the other side of the tooth column 9.

[0028] When long-distance construction is required, the operator takes out the adjusting handwheel 4 in the placing sleeve 16, and the cross column 17 fixedly installed at the bottom of the adjusting handwheel 4 is slidably inserted into the cross groove 19 opened on the upper surface of the worm 18. At this time, the adjusting handwheel 4 is twisted to drive the worm 18 to rotate. The worm 18 is in meshing transmission with the worm gear 6 on one side of it, and the worm gear 6 thus drives the rotating shaft 7 fixedly sleeved inside it to rotate. Under the rotation action of the rotating shaft 7, the rotating shaft 7 drives the gears 8 fixedly installed at both ends of it to rotate. The gears 8 are thus in meshing transmission with the tooth column 9 on one side of them, so that the tooth column 9 pushes the connecting side plate 3 fixedly connected with it to move. The connecting side plate 3 extends outwards with the assistance of the universal wheels 14, so as to extend the length of the whole device. After the extension is completed, the adjusting handwheel 4 is put back into the placing sleeve 16, and then by rotating the adjusting rods 11 on both sides of the connecting side plate 3, the grounding blocks 12 on both sides of the connecting side plate 3 are brought into contact with the ground, so as to ensure the stability of the connecting side plate 3, so that when carpenters are carrying out ceiling installation or building long cabinets, they can move and construct stably along the extended length, without climbing up and down and moving the position of the scaffolding back and forth, saving time and effort, improving work efficiency, and at the same time avoiding falling due to climbing, improving safety.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
