Description

Technical Field

[0001] This utility model relates to the field of scaffolding connectors, and in particular to a scaffolding connector for building construction. Background Technology

[0002] Scaffolding is a common tool in the construction industry, consisting of a frame made up of several vertical and horizontal bars. The connection structures of the vertical and horizontal bars are very diverse, and there are many existing technologies. However, the most common connector is composed of two pipe clamps arranged in a crisscross pattern. One clamps the vertical bar, and the other clamps the horizontal bar, thus fixing the intersecting vertical and horizontal bars together.

[0003] In existing technology, a large number of connectors are used when installing scaffolding, and each connector is equivalent to setting 4 pipe clamps, so at least eight bolts are needed. Therefore, the installation process is very time-consuming, and the workload is very large after all the scaffolding is installed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a scaffolding connector for construction, which can facilitate the convenient and quick installation and connection of scaffolding.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A scaffolding connector for building construction includes a connecting ball, to which multiple connecting pipes are fixedly connected. Multiple openings are formed at the outer ends of the connecting pipes, and rotating plates are rotatably connected to the interior of each opening. A hook is provided on the lower side of the end of each rotating plate, and a limit assembly is provided on the upper side of the end of each hook. A movable ring is movably connected to the outside of the connecting pipes, and multiple protrusions are fixedly connected to the inner wall of the movable ring. The lower ends of the protrusions are movably connected to the interior of the openings, and a pushing assembly is provided at the end of the movable ring.

[0007] Furthermore, the pushing component includes a retaining ring fixedly connected to the rear end of the movable ring, a threaded ring rotatably connected to the outside of the retaining ring, and a handle fixedly connected to the outside of the threaded ring.

[0008] Furthermore, the outer rear end of the connecting pipe is provided with a threaded area for engaging with a threaded ring.

[0009] Furthermore, a first toothed ring is fixedly connected to the outside of the threaded ring, and a second toothed ring that slidably engages with the first toothed ring is slidably connected to the outside of the movable ring. A fastener for fixing the second toothed ring is threadedly connected to the upper side of the second toothed ring.

[0010] Furthermore, the limiting component includes a lifting rod movably disposed at the end of the rotating plate, a pad fixedly connected to the lower end of the lifting rod, and a spring disposed on the upper side of the lifting rod corresponding to the pad.

[0011] Furthermore, the limiting assembly also includes an arc-shaped plate disposed on the upper side of the rotating plate, with limiting rods fixedly connected to both ends of the arc-shaped plate, and the lower end of the limiting rod passing through the end of the rotating plate.

[0012] Furthermore, a through hole is provided in the upper center of the arc-shaped plate, and a screw is provided inside the through hole. The lower end of the screw is threaded to the top of the lifting rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a rotating plate is rotatably connected inside the opening at the end of the connecting pipe, and a hook is provided on the lower side of the end of the rotating plate. The hook cooperates with the slot provided at the end of the scaffold, which can facilitate the quick and easy installation and connection of the scaffold. By rotating the threaded ring, the movable ring is pushed to move, and the movable ring drives the protrusion to press the rotating plate, so that the hook is tightly connected to the scaffold and prevents it from falling off.

[0015] 2. In this utility model, after the scaffolding is installed, the second toothed ring is pushed to engage with the first toothed ring. The second toothed ring can be fixed by rotating the fastener. By engaging the second toothed ring with the first toothed ring, the rotation of the threaded ring can be prevented, thereby improving the stability of the connector after connection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a scaffolding connector for construction, comprising a connecting ball 1, multiple connecting pipes 2 fixedly connected to the outside of the connecting ball 1, multiple openings 3 at the outer end of the connecting pipes 2, rotating plates 4 rotatably connected inside each opening 3, hooks 5 provided on the lower side of the end of the rotating plates 4, a movable ring 6 movably connected to the outside of the connecting pipes 2, multiple protrusions 7 fixedly connected to the inner wall of the movable ring 6, the lower ends of the protrusions 7 movably connected inside the openings 3, a retaining ring 8 fixedly connected to the rear end of the movable ring 6, a threaded ring 9 rotatably connected to the outside of the retaining ring 8, a handle 10 fixedly connected to the outside of the threaded ring 9, a threaded area 21 for cooperating with the threaded ring 9 provided at the outer rear end of the connecting pipe 2, a first toothed ring 11 fixedly connected to the outside of the threaded ring 9, a second toothed ring 12 cooperating with the first toothed ring 11 slidably connected to the outside of the movable ring 6, and a fastener 13 for fixing the second toothed ring 12 threadedly connected to the upper side of the second toothed ring 12.

[0024] The rotating plate 4 can rotate inside the opening 3. When connecting the scaffold, the end of the scaffold is inserted into the connecting pipe 2, so that the hook 5 on the rotating plate 4 engages with the slot on the end of the scaffold. The hook 5 hooks the scaffold, making the connection convenient and quick. The handle 10 drives the threaded ring 9 to rotate. The rotating threaded ring 9 engages with the threaded area 21, pushing the movable ring 6 to move outside the connecting pipe 2, thereby causing the protrusion 7 to slide inside the opening 3. The protrusion 7 engages with the inclined surface of the rotating plate 4, pressing down on the rotating plate 4, so that the hook 5 is tightly attached to the end of the scaffold, thus preventing the scaffold from falling off. After the scaffold is fixed, the second toothed ring 12 is pushed to engage with the first toothed ring 11 to prevent the threaded ring 9 from rotating. The fastener 13 is rotated to fix the second toothed ring 12, thereby fixing the threaded ring 9. This prevents the scaffold from loosening due to prolonged trampling by construction workers, thus improving the stability of the scaffold.

[0025] Reference Figure 1 , Figure 2 and Figure 4 A lifting rod 14 is movably provided at the end of the rotating plate 4. A pad 15 is fixedly connected to the lower end of the lifting rod 14. A spring 16 is provided on the outside of the lifting rod 14 corresponding to the upper side of the pad 15. An arc plate 17 is provided on the upper side of the rotating plate 4. Limiting rods 18 are fixedly connected to both ends of the arc plate 17. The lower end of the limiting rod 18 passes through the end of the rotating plate 4. A through hole 19 is provided in the middle of the upper side of the arc plate 17. A screw 20 is provided inside the through hole 19. The lower end of the screw 20 is threaded to the top of the lifting rod 14.

[0026] The arc-shaped plate 17 contacts the outer wall of the connecting pipe 2, and the spring 16 pushes the pad 15 to make the arc-shaped plate 17 fit tightly against the rotating plate 4. Thus, when not in use, the rotating plate 4 is stored in the opening 3. When connecting the scaffold, the scaffold is inserted into the connecting pipe 2. When inserted, the rotating plate 4 and the hook 5 are pushed to rotate upward. When the hook 5 moves to the slot on the scaffold, the rotating plate 4 rotates downward, so that the hook 5 engages with the slot to fix the scaffold. When the protrusion 7 presses down on the rotating plate 4, the rotating plate 4 rotates downward. The arc-shaped plate 17 is blocked by the connecting pipe 2, which can pull the lifting rod 14 and the pad 15 to move and compress the spring 16.

[0027] Working principle: The connector is installed at the end of the scaffold, so that the hook 5 engages with the slot at the end of the scaffold. Then, the handle 10 drives the threaded ring 9 to rotate. The rotating threaded ring 9 pushes the movable ring 6 to move outside the connecting pipe 2, thereby driving the protrusion 7 to move inside the opening 3. The protrusion 7 presses down on the rotating plate 4, so that the hook 5 is tightly engaged with the slot at the end of the connecting frame. Then, the second toothed ring 12 is pushed to engage with the first toothed ring 11. The second toothed ring 12 is fixed by rotating the fastener 13, thereby fixing the threaded ring 9 and preventing the threaded ring 9 from rotating and affecting the stability of the scaffold. When the protrusion 7 presses down on the rotating plate 4, the arc plate 17 is tightly attached to the outer wall of the connecting pipe 2. The rotating plate 4 is pressed down and rotates downward. The arc plate 17 pulls the lifting rod 14. The pad 15 compresses the spring 16, so that when the scaffold is not in use, the rotating plate 4 is stored in the connecting pipe 2 for easy placement on the outside of the scaffold.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
