[0024] The following is a further detailed description of a rod support seat provided by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer in combination with the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0025] like Figures 1 to 4 As shown, the rod support seat provided in this embodiment includes a connecting structure 10, a buckle structure 20 and a lifting structure 30. The connecting structure 10 is used to be connected to the support rod in a hoop-like manner, and the buckle structure 20 is used to lock and fix the connecting structure 10 and the support rod, and the connecting structure 10 and the support rod can also be loosened to remove the rod support seat from the support rod or move the rod support seat on the support rod. The support rod is usually arranged on the frame body, and at least two rod support seats are arranged on the support rod. When cleaning the scaffold rod, the two ends of the scaffold rod are placed on the lifting structure of the support seat.

[0026] The connection structure 10 includes a first clip 11 and a second clip 12, one end of the first clip 11 is hinged to one end of the second clip 12, for example, the first clip 11 and the second clip 12 are connected by a hinge 13, and the hinge 13 is a heavy hinge 13, so as to ensure that the first clip 11 and the second clip 12 have a large opening and closing angle and can withstand a large force. The first clip 11 and the second clip 12 are spliced ​​to form an internal cavity structure, and when the cross section of the support rod is a rectangular, hexagonal, pentagonal, circular, etc., the shape of the cavity structure matches it.

[0027] The buckle structure 20 is used to lock or open the open ends of the first buckle 11 and the second buckle 12. The buckle structure 20 can be an existing locking device, such as a buckle, a chain, a lock, or other fixing methods in the prior art. In a specific embodiment, the buckle structure 20 includes a hook 21, a connecting ear plate 22, a U-shaped ring buckle 24, and a wrench 23. The hook 21 is set at the open end of the first buckle 11, and the connecting ear plate 22 is set at the open end of the second buckle 12. One end of the first buckle 11 and the second buckle 12 is hinged is called a hinged end, and the other end is called an open end. The connecting ear plate 22 is hinged to the wrench 23, and the hinge point 25 is marked as point A. The wrench 23 can rotate along the hinge point 25. A horizontal through hole is also provided on the wrench 23 on the side of point A away from the hook 21, and a pin shaft 26 is provided in the through hole. Connecting holes are provided at both ends of the pin shaft 26, and the axis of the connecting hole is perpendicular to the pin shaft. The two ends of the opening of the U-shaped ring buckle 24 pass through the connecting holes and are fixed, and the closed end of the U-shaped ring buckle 24 is used to connect with the hook 21.

[0028] As an example, the wrench 23 includes a hand-held portion 231, a connecting portion 232 and a hinged portion 233 connected in sequence from head to tail, the hand-held portion 231 and the hinged portion 233 are located on the same side of the connecting portion 232 and on the side away from the hook 21, the bottom of the hinged portion is hinged to the connecting ear plate 22, the top of the hinged portion is provided with a through hole, and a pin 26 is provided in the through hole. The wrench 23 is rotated clockwise, and the pin 26 rotates clockwise around point A. When the pin 26 is located at the top of point A, the U-shaped ring buckle 24 can lock the hook 21, so that the first clip 11 and the second clip 12 are hooped on the support rod; then the wrench 23 is rotated counterclockwise, the pin 26 rotates counterclockwise around point A, the U-shaped ring buckle 24 releases the hook 21, and the first clip 11 and the second clip 12 are released from the support rod. At this time, the position of the buckle connection structure 10 on the support rod can be adjusted or the rod support seat can be removed from the support rod.

[0029] As an example, the open end of the U-shaped ring buckle 24 is provided with an external thread section, and the external thread section is provided with two positioning nuts, which are respectively located at both ends of the pin shaft connecting hole, and the U-shaped ring buckle 24 is fixedly connected to the pin shaft. By adjusting the position of the positioning nuts, the effective connection length of the U-shaped ring buckle 24 can be adjusted to match the hook 21.

[0030] The lifting structure 30 includes a support body 31 and three rollers 32. The bottom of the support body 31 is fixed to the top of the connecting structure 10, and the three rollers 32 are arranged on the top of the support body 31. For example, the support body 31 includes two vertical plates arranged in parallel and spaced apart. Branches are arranged on the support body 31, including a first branch 311 and a second branch 312. A first roller 321 is arranged on the first branch 311, and a second roller 322 and a third roller 323 are arranged on the second branch 312. The height of the first roller 321 is the same as or slightly higher than the height of the second roller 322, and the third roller 323 is located above the second roller 322. For example, the height difference between the first roller 321 and the second roller 322 is recorded as H1, and the vertical height difference between the third roller 323 and the second roller 322 is recorded as H2, and 0≤H1≤0.3H2. When the scaffold rod rotates, the rod contacts the first roller 321, the second roller 322 and the third roller 323, and drives the first roller 321, the second roller 322 and the third roller 323 to rotate. As an example, the first roller 321, the second roller 322 and the third roller 323 adopt bearing type rollers 32.

[0031] The rod support seat provided in this embodiment has a connection structure 10 that can be quickly fixed on the support rod through the buckle structure 20, and is convenient for operations such as moving the rod support seat and removing it from the support rod; the three rollers 32 are in three-point contact with the scaffolding rod, which can ensure the rod limit and smooth rotation movement, can quickly place and position the rod, and can also avoid damage to the rod surface coating caused by fixed contact. Therefore, the rod support seat provided in this embodiment can provide a lifting force for the rotating scaffolding rod, and is easy to disassemble and move to adapt to the length of different rods, and has the advantages of simple structure, low cost, easy operation, and strong adaptability.

[0032] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
