Description

Technical Field

[0001] This utility model relates to the field of scaffolding installation technology, and in particular to a scaffolding connection fastener structure. Background Technology

[0002] In the construction industry, scaffolding, as a temporary support structure, is widely used in building construction, bridge construction, equipment installation, and other projects. The safety and stability of scaffolding are directly related to the safety of construction workers and the progress of the project. As a key component of the scaffolding system, the structural design and performance of connecting couplers directly affect the overall load-bearing capacity, assembly and disassembly efficiency, and reliability of the scaffolding. Traditional scaffolding connecting couplers are mostly made of cast iron or steel, using bolts, wedges, or friction methods to fix the members together. Common coupler types include right-angle couplers, swivel couplers, and butt couplers, used to connect uprights, horizontal bars, and diagonal bars. However, these couplers cannot be adjusted appropriately according to actual conditions, affecting the stability of the fixing clips and highlighting the limitations of the device's usability. Therefore, we have redesigned a new scaffolding connecting coupler structure. Utility Model Content

The connection between the first fixing screw 16 and the fixing threaded post 14 is a threaded connection.

[0020] In the implementation scheme, the locking is achieved by setting the limiting locking ear 7 on the locking connecting plate 6 and the locking ear groove 13 inside the locking limiting groove 12, thus completing the initial connection and locking between the first fixed locking member 1 and the second fixed locking member 2. The limiting connecting plate 11 can rotate, thereby directly adjusting the angle of the second locking plate 8 and controlling the angle between the second locking plate 8 and the first locking plate 3 to achieve appropriate adjustment. This facilitates the adjustment of the second locking plate 8 and the first locking plate 3 to achieve a fixed connection in the horizontal direction, or to achieve a fixed connection in the vertical direction, improving the flexibility of the device.

[0023] Working principle:

[0024] The buckling is achieved by setting the limiting buckle ear 7 on the buckle connecting plate 6 and the locking ear groove 13 inside the buckle limiting groove 12, thus completing the initial connection and locking between the first fixed buckle 1 and the second fixed buckle 2. The limiting connecting plate 11 can rotate, thereby directly adjusting the angle of the second buckle plate 8 and controlling the angle between the second buckle plate 8 and the first buckle plate 3 to achieve appropriate adjustment. This makes it convenient to adjust the second buckle plate 8 and the first buckle plate 3 to the horizontal direction for fixed connection, or to adjust the second buckle plate 8 and the first buckle plate 3 to the vertical direction for fixed connection, improving the flexibility of the device. The buckling of the limiting buckle ear 7 and the locking ear groove 13 improves the connection stability. Then, the fixed connecting thread post 14 is inserted into the inside of the pin groove 17, and the fixed connecting thread post 14 is connected by 16, further improving the connection stability between the first fixed buckle 1 and the second fixed buckle 2.
