[0002] Scaffolding is a working platform set up to ensure the smooth progress of the construction process. Its main uses include solving vertical and horizontal transportation problems at the construction site and providing a platform for workers to operate and construct. Scaffolding is usually made of bamboo, wood, steel pipes or synthetic materials. In actual use, construction workers will assemble the scaffolding together to form floor supports and working platforms. At this time, scaffolding joints are needed for docking and fixing. Because multiple scaffoldings need to be connected and fixed when connecting, a joint that can be quickly fixed to speed up the construction progress is needed.

[0003] After searching, the Chinese patent publication number CN220790567U discloses a scaffolding connector, including an exposed portion and two plug-in portions respectively arranged at both ends of the exposed portion, and ribs are arranged on the outside of the plug-in portions, and the ribs abut against the inner wall of the vertical tube of the scaffolding to reduce the connection area between the connector and the scaffolding. By setting the exposed portion and the plug-in portion, ribs are arranged on the outside of the plug-in portions, and the ribs abut against the inner wall of the vertical tube of the scaffolding to reduce the connection area between the connector and the scaffolding.

[0004] In view of the problem that the above technology only uses straight-tube plug-in connection, which is prone to skewness, and when used for a scaffold with a fixed rod on one side, the fixed rod on one side of the scaffold cannot be fully utilized to improve the connection strength; therefore, a scaffold connection joint is proposed.

[0007] In some embodiments, support plates are fixedly connected to both ends of the shell, one end of the support plate is fixedly connected to a support tube, and one end of the support tube is fixedly connected to a scaffold.

[0008] In some embodiments, one end of the support plates on both sides is rotatably connected to a turntable 1 and a turntable 2 respectively.

[0009] In some embodiments, one end of the turntable 1 and the turntable 2 is respectively fixedly connected to a crown gear ring, one end of the crown gear ring is meshed with a fastening gear, and one end of the fastening gear is fixedly connected to the rotating shaft.

[0010] In some embodiments, one end of the turntable 1 and the turntable 2 is fixedly connected to the outer vortex and the inner vortex respectively, and one end of the turntable 1 and the turntable 2 is rotatably connected to the support shaft.

[0011] In some embodiments, one end of the outer vortex is threadedly connected to an outer clamping plate, one end of the inner vortex is threadedly connected to an inner clamping plate, and one end of the inner clamping plate and the outer clamping plate are slidably connected to the support plate.

[0012] In some embodiments, one end of the support plate is fixedly connected to the limit plate, and one end of the limit plate is slidably connected to the inner clamping plate and the outer clamping plate.

[0013] In some embodiments, a positioning bolt hole is opened at one end of the support tube.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] The utility model drives the worm gear to drive the lifting screw to move into the shell by rotating the rotating shaft, and then hooks the fixing rod through the fixing hook to fix the scaffolding on the upper and lower sides to improve the strength of the connection. In addition, due to the self-locking property of the worm and gear transmission, it can effectively prevent the connection part of the fixing hook from becoming loose due to shaking, and the connection speed is faster and more secure.

In addition, due to the self-locking property of the worm 10 and the gear transmission, it can effectively prevent the connecting part of the fixing hook 6 from becoming loose due to shaking.

[0030] In this embodiment, the two ends of the shell 1 are fixedly connected with support plates 12, one end of the support plate 12 is fixedly connected with a support tube 3, one end of the support tube 3 is fixedly connected to the scaffolding 2, the support plate 12 and the support tube 3 can be pressed against one end of the scaffolding 2 for support and fixation, and the support tube 3 is sleeved on the outside of one end of the scaffolding 2.
