[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0023] like Figure 1-4 As shown, a novel disc-type scaffolding comprises a vertical pole 2 and a support rod assembly connected between two adjacent vertical poles 2, wherein the lower end of the vertical pole 2 is connected to the bottom plate 11 through a telescopic adjustment part. The telescopic adjustment part comprises a second screw rod 1, wherein the lower end of the second screw rod 1 is fixedly connected to the bottom plate 11, and the upper end threaded sleeve 7 is arranged at the lower end of the vertical pole 2. By rotating and adjusting the extension length of the second screw rod 1 at the lower end of the vertical pole 2, the overall height of the vertical pole 2 can be effectively adjusted, thereby being able to adapt to the installation needs of complex construction conditions such as potholes and slopes.

[0024] Two movable sleeves 3 are coaxially sleeved on the vertical pole 2. The movable sleeves 3 are adjustable up and down on the vertical pole 2. A circular turntable 4 is coaxially rotatably mounted on the movable sleeve 3. A locking piece for fixing the circular turntable 4 is provided on the movable sleeve 3. The circular turntable 4 is provided with multiple mounting holes.

[0025] Among them, a slide groove 21 is provided on the outer wall of the vertical rod 2 along its length direction, and a plurality of slots 22 with a depth greater than the slide groove 21 are connected and provided on one side of the slide groove 21 along its length direction, and the slots 22 are arranged at equal intervals. A through hole 30 is provided on the movable sleeve 3 along its radial direction, and the inner end of the block 31 slidingly arranged in the through hole 30 is slidably matched with the slide groove 21 and can be inserted into the corresponding slot 22, and the other end of the block 31 extends outward. In addition, a limiting portion 311 with a diameter greater than the through hole 30 is provided in the middle of the block 31, which can effectively limit the length of the block 31 pulled out of the through hole 30. A spring 32 is sleeved on the block 31, and the two ends of the spring 32 are respectively in contact with the limiting portion 311 and the inner wall of the movable sleeve 3. Under the elastic force of the spring 32, a force close to the vertical rod 2 can be applied to the block 31, so that the block 31 slides between the slide groove 21 and different slots 22. When in use, first pull the outer end of the block 31 to disengage it from the slot 22, and then rotate the movable sleeve 3 to slide the block 31 into the slide slot 21. When the movable sleeve 3 is adjusted up and down to change its height, the block 31 slides in the slide slot 21. After the movable sleeve 3 is adjusted to the right position, it rotates sideways, and under the elastic force of the spring 32, the block 31 is stuck in the corresponding slot 22, thereby realizing rapid adjustment of the movable sleeve 3, which is simpler and more convenient to use.

[0026] The locking member includes a first locking ring 41, a second locking ring 6 and a threaded sleeve 7. The first locking ring 41 is coaxially fixed to the bottom of the circumferential turntable 4. A limit groove 33 is vertically provided on the outer wall of the movable sleeve 3. The second locking ring 6 is movably sleeved outside the movable sleeve 3, and its inner wall is provided with a protrusion 62 that slides and clamps with the limit groove 33. Under the cooperation of the protrusion 62 and the limit groove 33, the second locking ring 6 can only slide up and down. The outer wall below the movable sleeve 3 is also provided with an external thread. The threaded sleeve 7 is provided below the second locking ring 6 and sleeved on the external thread. The threaded sleeve 7 is in contact with the lower end of the second locking ring 6, and the opposite end faces of the two locking rings are respectively provided with mutually meshing teeth 61. The threaded sleeve 7 can be in the form of a rotating nut, which can be screwed and adjusted with a wrench.

[0027] The discs of the existing disc-type scaffolding are all fixedly installed with the upright pole 2. After the upright pole 2 is installed, if the mounting holes on the disc do not correspond, it needs to be removed and reinstalled. After the upright pole 2 is installed, the device can rotate the circular turntable 4 horizontally on the movable sleeve 3 by rotating the circular turntable 4, and the mounting hole above it can be rotated at an angle. Then, the second locking ring 6 is pressed against the first locking ring 41 at the bottom of the circular turntable 4 by rotating the threaded sleeve 7, so that the engaging teeth 61 on the two positioning rings are engaged, thereby realizing the rapid locking and fixation of the circular turntable 4, which is very convenient to use.

[0028] The support rod assembly includes two support rods. The support rods between the vertical poles 2 can be installed in a variety of ways, such as one support rod is installed horizontally, the other support rod is installed obliquely, or the two support rods are installed between the two vertical poles 2 in an x-shaped structure. The support rod includes a sleeve rod 51 and two first screw rods 52. One end of the two first screw rods 52 is respectively threadedly sleeved 7 and arranged at both ends of the sleeve rod 51. The other ends of the two first screw rods 52 are fixedly connected to the mounting holes of the circumferential turntable 4 on the two adjacent vertical poles 2 through a connecting member 54. One end of the connecting member 54 is hinged to the first screw rod 52, and the other end is provided with a latch structure 53. The latch structure 53 penetrates through the pin hole of the connecting member 54 and the mounting hole of the circumferential turntable 4. The latch structure 53 can be a pin, or a bolt that penetrates the pin hole and the mounting hole and is then fixed with a nut.

[0029] By rotating and adjusting the extension length of the two first screw rods 52 at both ends of the sleeve rod 51, the overall length of the support rod can be adjusted, and then the connecting piece 54 is installed in the mounting hole of the circular turntable 4 on the adjacent vertical pole 2, so that the device can adapt to the installation and use of vertical poles 2 with different spacings, can be used in more complex construction conditions, and is more convenient to use.

[0030] When using the utility model, the overall support height of the vertical pole 2 can be changed by rotating and adjusting the second screw rod 1; the height of the movable sleeve 3 on the vertical pole 2 can be adjusted up and down by cooperating with the clamping block 31, the slide groove 21 and the clamping groove 22 as needed; the circumferential turntable 4 is rotated and the threaded sleeve 7 is screwed to drive the second locking ring 6 to fix it, so that the mounting hole above it is rotated at an angle to facilitate the installation of the support rod assembly; after adjusting the overall length of the support rod, the support rod assembly is installed on the circumferential turntable 4 of two adjacent vertical poles 2 using the connecting piece 54. The installation and adjustment of the device is very convenient, the structural stability is strong, and the construction efficiency can be significantly improved.
