[0002] Scaffolding for indoor use in buildings is equipment that provides support and a safe working platform when performing construction and maintenance work in indoor environments. They are usually lightweight, easy to assemble and move, and are designed to provide working platforms and support in local areas of indoor buildings.

[0003] During indoor construction, workers need to assemble scaffolds for use when they are working on walls and roofs. In order to ensure that the assembled scaffolds can provide workers with a sufficient working platform, they have a certain width so that they can be pushed and moved when they are displaced indoors. However, when working indoors, they are blocked by walls. When working in other rooms, the scaffolds are larger than the width of door openings, so the workers need to dismantle them and reinstall them for use. As a result, it is not convenient to relocate the existing scaffolds at any time when they are used indoors. Utility Model Content

[0018] In this embodiment: the bottom rod 1 is the carrier of the load-bearing device, and the extension rod 12 slidably connected at both ends of the bottom rod 1 is installed and fixed to the top end of the extension rod 12 facing the vertical rod 2, so that the four extension rods 12 can form the main supporting frame rod of the scaffolding, and the hinged rod 22 is installed through the slide groove 21 opened on the vertical rod 2. The two hinged rods 22 are hinged to each other so that one end slides on the inner wall of the slide groove 21, so that after the extension rod 12 slides outward at both ends of the bottom rod 1, one end of the hinged rod 22 can slide on the inner wall of the slide groove 21, and the angle between the two hinged rods 22 changes, so that the vertical rod 2 slides on the extension rod 12, and when the spacing between them is affected, the spacing between the vertical rods 2 can be adjusted by changing the angle between the hinged rods 22. After the angle between the hinged rods 22 is changed, the extension rod 12 is extended to the outermost end. At this time, the position of one end of the hinged rod 22 in the slide groove 21 corresponds to the support hole 23 provided on the upright 2. At this time, the positioning frame 24 can be inserted into the support hole 23 so that one end of the positioning frame 24 can be in the slide groove 21, and the position of one end of the hinged rod 22 in the slide groove 21 is limited. At this time, the hinged rod 22 is limited by the support hole 23 and the positioning frame 24, which can effectively limit the distance between the uprights 2, so that the distance between the uprights 2 is fixed, so that there is enough distance between the uprights 2 to install the frame plate 33, and the fixing block 3 fixedly connected to the top of the upright 2 is used to install the adjustment rod 31, between the uprights 2 After the distance is limited by the hinge rod 22 at the maximum, the support frame 35 can be installed through the fixing rod 34 fixedly connected between the two flush vertical rods 2. After the support frame 35 is installed on the fixing rod 34, the support frame 35 can support the adjustment rod 31 hinged on the fixing block 3, so that the adjustment rod 31 is supported on the support frame 35 and will not rotate downward, so that the support rod 32 between the two adjustment rods 31 can be supported by the adjustment rods 31 horizontal at both ends, so that the support rod 32 and the adjustment rod 31 are kept horizontal, so that the adjustment rod 31 and the support rod 32 can effectively provide a horizontal support surface for the frame plate 33, so that the staff can work on the frame plate 33. When the entire device needs to be moved indoors, it can be By separating the positioning frame 24 from the support hole 23, after the positioning frame 24 is separated from the support hole 23, the extension rod 12 slidably connected at both ends of the bottom rod 1 can be retracted. When the extension rod 12 is retracted, since one end of the hinged rod 22 slides in the slide groove 21, the angle between the two hinged rods 22 can be changed, so that the vertical rod 2 can effectively adjust its spacing. At the same time, after the frame plate 33 is separated from the adjustment rod 31 and the support rod 32, the support frame 35 is separated from the fixed rod 34, so that the support rod 32 and the adjustment rod 31 can change their angles, so that the overall width of the device can be shortened, so that the staff can push the device to pass through the indoor doorway, avoiding the device width required for the operation being too large and unable to pass through the doorway for position transfer.This allows the device to avoid separation for position adjustment, making it easier for workers to transfer the device.

[0019] Support grooves 11 matching the extension rod 12 are provided at both ends of the bottom rod 1, matching limit holes 13 are provided on the bottom rod 1 and the extension rod 12, and limit rods 14 are inserted between the limit holes 13; the support grooves 11 provided at both ends of the bottom rod 1 are used to allow the extension rod 12 to slide on the two ends of the bottom rod 1. After the extension rod 12 slides to the outermost end, the extension rod 12 and the limit holes 13 provided on the bottom rod 1 can correspond to each other up and down, and are limited by the limit rods 14 to ensure that the extension rod 12 will not separate from the bottom rod 1, thereby ensuring its stability.

[0020] A limiting groove 211 is provided on the inner wall of the slide groove 21, and a slider 221 matching the limiting groove 211 is fixedly connected to the hinged rod 22, and the slider 221 is slidably connected to the limiting groove 211; the limiting groove 211 provided on the inner wall of the slide groove 21 is used to limit the slider 221 on the hinged rod 22, so that the hinged rod 22 can slide on the inner wall of the slide groove 21, while avoiding the separation of the hinged rod 22 and the vertical rod 2, thereby ensuring the supporting and reinforcing effect of the hinged rod 22 on the vertical rod 2.

[0021] A connecting groove 311 is fixedly connected to one end of the adjusting rod 31, and connecting blocks 321 matching the connecting groove 311 are provided at both ends of the support rod 32, and the connecting groove 311 is hinged to the inner wall of the connecting block 321; the connecting groove 311 fixedly connected to one end of the adjusting rod 31 is used to be hinged with the connecting blocks 321 at both ends of the support rod 32, so that the support rod 32 is hinged between the adjusting rods 31, and after the distance between the vertical poles 2 is reduced, the angle can be changed, thereby avoiding the limitation caused by the reduction of the distance between the vertical poles 2.

[0022] A reinforcement rod 25 is fixedly connected between the uprights 2, a fixing rod 34 is fixedly connected between the uprights 2, matching fixing holes 341 are provided on the fixing rod 34 and the support frame 35, and a support block 351 is fixedly connected to the top of the support frame 35; the reinforcement rod 25 fixedly connected between the uprights 2 is used to reinforce the stability between the uprights 2, the fixing rod 34 is used to install the support frame 35 so that the support frame 35 can support and reinforce the adjustment rod 31, the fixing hole 341 is used to support and fix the support frame 35 and the fixing rod 34 through a pin, and the support block 351 is used to support the middle section of the frame plate 33 so that the frame plate 33 is horizontally supported between the uprights 2.

[0023] The working principle and use process of the utility model are as follows: when the entire device needs to be transferred indoors, by separating the positioning frame 24 from the support hole 23, and the frame plate 33 from the adjustment rod 31 and the support rod 32, the extension rod 12 that is slidably connected at both ends of the bottom rod 1 can be retracted. When the extension rod 12 is retracted, since one end of the hinged rod 22 slides in the slide groove 21, the angle between the two hinged rods 22 can be changed. At the same time, the support rod 32 and the adjustment rod 31 can change their angles, thereby shortening the overall width of the device, so that the staff can push the device to pass through the door opening in the room, avoiding the large width of the device required for the operation and being unable to pass through the door opening for position transfer, thereby preventing the device from being separated for position adjustment, making the device convenient for the staff to transfer it.
