Description

Technical Field

[0001] This utility model relates to the field of scaffolding installation technology, and in particular to a quick connection device for scaffolding fasteners. Background Technology

[0002] In the construction industry, scaffolding, as a temporary support structure, is widely used in housing construction, bridge construction, equipment installation, and other projects. Traditional scaffolding typically consists of steel pipes, couplers, and scaffold boards, with couplers used to connect the steel pipes to form a stable frame structure. Common coupler types include right-angle couplers, swivel couplers, and butt couplers, which fix the steel pipes by bolting. Each coupler needs to be tightened individually with a bolt, which is cumbersome, especially when erecting large scaffolding, where workers need to frequently tighten bolts, which is time-consuming and labor-intensive. Traditional couplers are also prone to loosening under dynamic loads (such as wind loads or worker movement), requiring regular inspection and reinforcement, increasing maintenance costs. Therefore, we have redesigned a quick-connect device for scaffolding couplers. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick connection device for scaffold fasteners, including a first connecting member, a second connecting member and a third connecting member. A scaffold fastener is detachably installed on one side of the top surface of the first connecting member. A scaffold fastener fastening groove is formed on one side of the scaffold fastener. A pin limiting groove is formed inside one side of the scaffold fastener. A pin connecting rod is fixedly installed on one side of the top surface of the second connecting member. A threaded connecting groove is formed inside the pin connecting rod. A fastening screw is detachably installed inside the threaded connecting groove. A limiting top nut is fixedly connected to one side of the top surface of the fastening screw.

[0010] Compared with related technologies, the quick-connect device for scaffolding couplers provided by this utility model has the following advantages:

[0011] This utility model provides a quick-connect device for scaffolding couplers. By setting scaffolding clips on all four sides of the first connector, it is convenient to achieve scaffolding fixation in multiple directions. The second connector can achieve scaffolding fixation at three angles, and the third connector can achieve scaffolding fixation at a vertical angle. The multiple directions and numbers of scaffolding clips can be used to improve the versatility of the device. The connection between the scaffolding clips and the connectors is achieved by directly inserting a pin into the pin limiting groove of the connecting rod, and then installing it directly into the pin connecting rod with a fastening screw. For the fixing operation between the scaffolding clips and the second connector, the top nut of the limiting nut is larger than the size of the pin limiting groove to achieve a top seal of the pin limiting groove, avoiding the problem of rainwater erosion of the pin connecting rod and the fastening screw, and improving their service life.

[0012] This utility model provides a quick-connect device for scaffolding couplers. Multiple rubber friction pads are installed inside the scaffolding coupler fastening groove to increase friction. The connecting shaft can be rotated to adjust the angle, directly opening the scaffolding coupler fastening groove. For the scaffolding coupler, rotating the top plate adjusts the position and height of the threaded compression rod inside the connecting block, directly inserting the coupler head pin into the limiting fastening groove, thus achieving the snap-locking operation between the coupler head and the coupler disc. This improves the stability of the scaffolding coupler for fixing the scaffolding. Afterwards, the coupler head can be directly removed for disassembly of the scaffolding coupler, facilitating both installation and disassembly, and improving the device's usability.
