Technical Field

[0001] This utility model relates to the field of combined mechanism technology, and in particular to a combined junction box. Background Technology

[0002] As a key component in electrical wiring systems, junction boxes are widely used in building indoor wiring, industrial equipment rooms, smart home wiring, and other scenarios. Their core function is to branch, connect, and protect wires.

[0003] Traditional junction boxes can only be installed directly through the fixing holes on both sides of the outer shell, and can only be used on flat surfaces. If they encounter non-flat surfaces such as curved brackets or irregular equipment surfaces, additional adapters or holes need to be welded or drilled, which increases construction costs and time. Moreover, multiple parts such as screws and nuts need to be used at the same time when fixing them, and tools such as screwdrivers and wrenches are required, making it difficult for a single person to operate. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor adaptability and time-consuming and laborious operation of traditional junction boxes in the prior art, and to provide a modular junction box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a combined junction box, comprising a junction box body, a connecting mechanism fixedly connected to the outer surface of the junction box body, the connecting mechanism comprising a support arm, a connecting block fixedly connected to the outer surface of the support arm, a fixing opening provided on the inner wall of the connecting block, a first connecting hole provided on the inner wall of the connecting block, a protrusion engaged with the outer surface of the connecting block, a second connecting hole provided on the inner wall of the protrusion, a latch provided on the outer surface of the protrusion, a rotating handle fixedly connected to the outer surface of the protrusion, and a fixing mechanism rotatably connected to the inner wall of the rotating handle, the fixing mechanism comprising a screw.

[0006] In a preferred embodiment, the outer surface of the screw is rotatably connected to the inner wall of the rotating handle.

[0007] In a preferred embodiment, a connecting post is fixedly connected to the outer surface of the screw, a fixing post is fixedly connected to the outer surface of the screw, a threaded groove is formed on the outer surface of the screw, and a handle is threadedly connected to the outer surface of the threaded groove.

[0008] In a preferred embodiment, the outer surface of the support arm is fixedly connected to the outer surface of the junction box body.

[0009] In a preferred embodiment, the outer surface of the connecting post is engaged with the inner wall of the bayonet.

[0010] In a preferred embodiment, the outer surface of the fixing post is engaged with the inner wall of the fixing opening.

[0011] In a preferred embodiment, a support plate is rotatably connected to the outer surface of the screw.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model, through its designed connecting mechanism, eliminates the need for screwdrivers, wrenches, or other tools when installing the junction box. Simply hold the rotating handle and insert the screw into the corresponding hole. Initial fixation is achieved through the engagement of the fixing post and fixing port, and the connecting post and locking slot. Finally, rotating the handle completes the reinforcement. This method is more efficient than traditional screw fixing, eliminating the need for additional welding adapters or drilling. The engaging structure of the support arm, connecting block, and protrusion allows for direct adaptation to various installation surfaces such as flat walls, curved equipment brackets, and ceiling joists, reducing pre-construction preparation and adapting to a wider range of scenarios.

[0021] In this embodiment, two support arms 21 are fixedly connected to the outer surface of the junction box body 1. The connecting block 22 is fixedly connected to the support arms 21, and the junction box body 1 is fixed by fixing the connecting block 22. The first connecting hole 24 is opened on the connecting block 22. The center of the first connecting hole 24 is circular to facilitate the insertion of the screw 31, and the two ends are slots. The slots are slightly larger than the fixing post 33 to facilitate the insertion of the fixing post 33. The second connecting hole 27 is opened on the inner wall of the connecting block 22. The slot of the bayonet 28 cooperates with the fixing post 33, and the fixing post 33 is locked in the inner wall of the connecting block 22. Inside the bayonet 28, a protrusion 25 is also engaged with the outer surface of the connecting block 22. A second connecting hole 27 is opened on the inner wall of the protrusion 25. The inner wall of the second connecting hole 27 is slightly larger than the connecting post 32. The connecting post 32 is engaged with the bayonet 28. A rotating handle 26 is fixedly connected to the outer surface of the protrusion 25 for easy operation by the operator. The connecting post 32 and the fixed post 33 are both fixedly connected to the screw 31. By rotating the rotating handle 26, the screw 31 is rotated. The connecting block 22 is fixedly connected to the screw 31 by engaging the fixed post 33 fixed to the screw 31 with the fixed opening 23.

[0022] Example 2 like Figures 1-5As shown, a connecting post 32 is fixedly connected to the outer surface of the screw 31, and a fixing post 33 is fixedly connected to the outer surface of the screw 31. The outer surface of the fixing post 33 is engaged with the inner wall of the fixing port 23. A threaded groove 34 is opened on the outer surface of the screw 31. A support plate 4 is rotatably connected to the outer surface of the screw 31. A handle 35 is threadedly connected to the outer surface of the threaded groove 34. The outer surface of the connecting post 32 is engaged with the inner wall of the bayonet 28.

[0023] In this embodiment, by designing a fixing mechanism 3, the threaded groove 34 on the outer surface of the screw 31 is connected to the threaded connection on the inner wall of the handle 35, which facilitates the connection between the screw 31 and the inner wall of the support plate 4. On one side of the screw 31, the handle 35 is engaged with the support plate 4, and on the other side of the screw 31, the fixing post 33 is engaged with the fixing port 23, which facilitates the fixed connection of the junction box body 1 to the support plate 4. After connection, rotating the handle 35 tightens the screw 31 and the handle 35, thereby making the connection more secure.

[0024] Working principle: like Figures 1-5 As shown, align the component with the protrusion 25 on the support plate 4, so that the outer surface of the connecting block 22 engages with the protrusion 25, completing the initial positioning. At this time, the first connecting hole 24 and the fixing port 23 on the connecting block 22 will form a corresponding passage with the second connecting hole 27 and the locking port 28 on the protrusion 25, preparing for subsequent fixing. The operator holds the rotating handle 26 and inserts the screw 31 through the second connecting hole 27 of the protrusion 25 and the first connecting hole 24 of the connecting block 22 in sequence. The fixing post 33 on the screw 31 will move along with the screw 31 as it is inserted. The screw 31 is inserted and finally engages with the fixing port 23 on the inner wall of the connecting block 22. At the same time, the connecting post 32 on the screw 31 engages with the slot 28 of the protrusion 25, achieving initial locking between the junction box and the protrusion 25. The other end of the screw 31 extends out of the support plate 4, and the threaded groove 34 on its outer surface matches the thread on the inner wall of the handle 35. During the tightening process, the screw 31 will drive the connecting block 22, the support arm 21 and the junction box body 1 to move closer to the support plate 4 until the junction box body 1 is firmly fixed on the support plate 4, completing the entire installation process.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
