Description

Technical Field

[0001] This utility model relates to the technical field of electrical equipment installation and fixing, and in particular to a tool-free electrical junction box fixing buckle device. Background Technology

[0002] As an indispensable component of the power system, the installation and fixing method of electrical junction boxes directly affects the safety and maintenance efficiency of the system. At present, there are various fixing methods for junction boxes on the market, mainly including snap-fit ​​fixing and magnetic fixing. Snap-fit ​​fixing uses the deformation of elastic snaps to achieve fixing, which is easy to operate, but the snaps are prone to fatigue failure after long-term use. Magnetic fixing uses magnetic attraction to fix, which is easy to disassemble, but the magnetic force is greatly affected by the environment and its stability is insufficient.

[0003] A search revealed Chinese Patent Publication No. CN213027945U, which discloses a novel photovoltaic cable junction box fixing device. The device includes a box body and a cover. A handle is fixedly installed on the top of the box body, and support columns are fixedly installed on both sides of the box body. An upper buckle is fixedly connected to the end of each support column away from the box body. A through block is fixedly inserted into the bottom of the box body, and a hand-tightening conduit is threaded onto the inner wall of the through block. A pressure plate bolt is threaded onto the rear surface of the box body, and a pressure plate is wrapped around the outer surface of the pressure plate bolt. A fixing bolt is inserted into the rear surface of the box body, and a washer is fixedly installed at the bottom of the fixing bolt. An external hexagonal bolt is threaded onto the bottom of the fixing bolt, and a soft pad is movably inserted into the right side of the external hexagonal bolt. A fixing post is fixedly installed on the left side of the external hexagonal bolt, and a threaded groove is formed on the outer surface of the fixing post. A pointed post is fixedly installed on the left side of the fixing post, allowing the fixed junction box to be easily removed for replacement or repair. This is very convenient, and the overall internal sealing effectively reduces the possibility of water entering the box body.

[0004] The above-mentioned utility model solution uses lower buckles fixedly installed on both sides of the lid and upper buckles fixedly installed on both sides of the box body to fasten together. However, in actual use, the buckle fixing method uses the deformation of the elastic buckle to achieve fixation, which is simple to operate, but the buckles are prone to fatigue failure after long-term use.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of an electrical junction box fixing buckle device that can be disassembled without tools, comprising a support frame 1, a threaded rod 2 rotatably connected inside the support frame 1, a rotating block 3 fixedly connected to the outer wall of the threaded rod 2, a movable column 4 threadedly connected to the outer wall of the threaded rod 2, a buckle arm 5 slidably connected to the outer wall of the movable column 4, a limit rod 6 rotatably connected inside the buckle arm 5, both ends of the limit rod 6 being fixedly connected to the inside of the support frame 1, a buckle head 7 slidably connected to the outer wall of the buckle arm 5, a buckle groove 8 opened inside the buckle head 7, the outer wall of the buckle arm 5 slidably connected to the inner wall of the buckle groove 8, a fixing plate 9 fixedly connected to the outer wall of the buckle head 7, and a support assembly 10 provided on the outer wall of the support frame 1;

[0040] Specifically, the support frame 1 limits the threaded rod 2, and the rotating block 3 drives the moving column 4 to move. As the moving column 4 moves, it drives the latch arm 5 to rotate on the outer wall of the limiting rod 6. The support frame 1 provides fixed support for the limiting rod 6, which in turn limits the latch arm 5. The latch arm 5 then slides on the inner wall of the latch groove 8, and the latch groove 8 inside the latch head 7 limits the latch arm 5. This allows for quick installation or removal of the junction box body 20, improving operational efficiency. The fixing plate 9 provides fixed support for the latch head 7.

[0041] Reference Figure 1 and Figure 4 The support assembly 10 includes a fixed frame 1001, the outer wall of which is fixedly connected to the outer wall of the support frame 1. A fixed plate 1002 is fixedly connected inside the fixed frame 1001. A motor 11 is fixedly connected inside the fixed plate 1002. A rotating column 12 is fixedly installed at the output end of the motor 11. A rotating plate 13 is fixedly connected to the outer wall of the rotating column 12. A connecting shaft 14 is fixedly connected to the outer wall of the rotating plate 13. A connecting plate 15 is rotatably connected to the outer wall of the connecting shaft 14. A fixed shaft 16 is rotatably connected inside the connecting plate 15. A moving block 17 is fixedly connected to the outer wall of the fixed shaft 16. A sliding block 18 is fixedly connected to the outer wall of the moving block 17.

[0042] Specifically, the fixing bracket 1001 provides fixed support for the fixing plate 1002, the fixing plate 1002 provides fixed support for the motor 11, the motor 11 drives the rotating column 12, which in turn drives the rotating plate 13 to rotate, the rotating plate 13 drives the connecting shaft 14, which in turn drives the connecting plate 15 to rotate, the connecting shaft 14 connects the rotating plate 13 and the connecting plate 15, the connecting plate 15 drives the fixing shaft 16, which in turn drives the moving block 17 to move, the moving block 17 provides fixed support for the fixing shaft 16, and the fixing shaft 16 connects the moving block 17 and the connecting plate 15, and the movement of the moving block 17 simultaneously drives the sliding block 18 to move.

[0043] Reference Figure 4 The outer wall of the sliding block 18 is slidably connected to the outer wall of the fixing plate 1002, and the outer wall of the sliding block 18 is slidably connected to the inner wall of the fixing frame 1001; the outer wall of the sliding block 18 is fixedly connected to the clamping plate 19, the outer wall of the clamping plate 19 is slidably connected to the outer wall of the fixing frame 1001, and the outer wall of the clamping plate 19 is slidably connected to the junction box body 20.

[0044] Specifically, the sliding block 18 drives the clamping plate 19 to limit and fix the junction box body 20. The fixing bracket 1001 and the fixing plate 1002 provide auxiliary support and limit the sliding block 18, thus facilitating the replacement of different junction box bodies 20 to adapt to different specifications and models. When the junction box body 20 malfunctions or needs to be upgraded, only part of the junction box body 20 needs to be replaced, without replacing the entire fixing buckle device, which greatly reduces maintenance costs and improves the service life of the equipment.

[0045] Working principle: When the device is needed, the motor 11 inside the fixed plate 1002 is started. The motor 11 drives the rotating column 12 to rotate the rotating plate 13. The rotating plate 13 drives the connecting shaft 14 to rotate the connecting plate 15. The connecting plate 15 drives the fixed shaft 16 to move the moving block 17. While the moving block 17 is moving, the sliding block 18 slides inside the fixed frame 1001. The sliding block 18 drives the clamping plate 19 to limit and fix the junction box body 20, so as to facilitate the replacement of different junction box bodies 20 to adapt to different specifications and models of junction box bodies 20.

[0046] By rotating the rotating block 3 inside the support frame 1, the moving column 4 is moved. As the moving column 4 moves, the latching arm 5 rotates on the outer wall of the limiting rod 6, and then slides on the inner wall of the slot 8, thereby enabling the quick installation or removal of the junction box body 20. This improves operational efficiency. This device not only enables the quick installation or removal of the junction box body 20 without additional tools, simplifying the operation process and reducing maintenance costs, but also ensures its stability and the safety of electrical equipment. Furthermore, it allows for convenient replacement of different junction box bodies 20 to quickly adapt to different specifications and models of junction box bodies 20.
