They are equipped with circuit breakers of appropriate current capacity. The function of the busbar duct plug-in box is to draw power from the plug-in interface on the busbar duct and distribute the power to the electrical equipment through the switch inside the plug-in box.

[0003] During the installation of electrical systems, the connection between the plug box and the busbar trunking requires multiple steps, such as aligning the plugs and tightening the screws. Each step requires a certain amount of time and effort, which slows down the overall installation speed and increases the workload and working time of the installers. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a plug-in box for busbar trunking. By pulling the pull plate, the limiting strip is driven, and the limiting strip drives the plug rod. At this time, the plug block and the connecting block are inserted into the connecting box. Then, when the pull plate is released, the tension spring pulls the limiting plate, and the limiting plate drives the plug rod to be inserted into the fixing hole for fixation. This makes installation and disassembly more convenient and saves time and labor costs.

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

[0024] 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.

[0025] Reference Figure 2 - Figure 4 This utility model provides an embodiment of a busbar trunking plug-in box, comprising: a busbar trunking body 1 serving as the connecting main body; a connecting box 2 fixedly connected to the inner wall of the busbar trunking body 1; plug rods slidably connected to both sides of the inner wall of the connecting box 2; a limit plate 4 fixedly connected to one opposite end of each plug rod 3; a pull plate 5 fixedly connected to one opposite end of each limit plate 4; a tension spring 7 provided between each limit plate 4 and the inner wall of the connecting box 2; a plug block 8 slidably connected to the inner wall of the connecting box 2; and multiple plug blocks slidably connected to the outer wall of the plug block 8. Each connecting block 10 has multiple plugs 9 fixedly connected to its bottom end. The plug 8 is connected to the plug box body 19 via a rotating assembly. One end of each tension spring 7 is connected to the limiting plate 4, and the other end of each tension spring 7 is connected to the inner wall of the connecting box 2. Limiting strips 6 are fixedly connected to both sides of the outer wall of the limiting plate 4. The outer walls of the limiting strips 6 are slidably connected to the inner wall of the connecting box 2. The inner wall of the connecting block 10 is provided with fixing holes 11 corresponding to the plug rod 3. The outer walls of the connecting block 10 are slidably connected to the inner wall of the connecting box 2.

[0026] Specifically, when it is necessary to connect the plug-in box body 19 to the busbar trunking body 1, the operator pulls the pull plate 5. As the pull plate 5 moves, it simultaneously moves the limit strip 6. The movement of the limit strip 6 then pushes the plug rod 3 to move. At this time, the plug block 8 and the connecting block 10 are aligned and inserted into the connecting box 2. After the plug block 8 and the connecting block 10 are fully inserted, the pull plate 5 is released. The moment the pull plate 5 is released, the tension spring 7 activates, pulling the limit plate 4. During the movement of the limit plate 4, the plug rod 3 is inserted into the fixing hole 11, thus achieving the connection between the plug-in box body 19 and the busbar trunking body 1. The fixed connection of body 1 greatly simplifies the installation process and saves time and labor costs. When disassembly is required, pull the pull plate 5 again. The pull plate 5 drives the plug rod 3 to disengage from the fixed hole 11, and then the plug box body 19 can be easily taken out. During the process of inserting the plug block 8 into the connection box 2, the plug connector 9 is simultaneously inserted into the busbar trunking body 1 to achieve electrical connection. In addition, when the limit plate 4 moves, it will drive the limit strip 6 to slide in the connection box 2. The presence of the limit strip 6 enhances the stability of the limit plate 4 during the movement process and ensures that the entire operation process is safe and reliable.

[0027] Reference Figure 1 , Figure 5 and Figure 6 The rotating assembly includes a fixed base 12 fixedly connected to the top of the plug block 8, a fixed cylinder 13 fixedly connected to the inner wall of the fixed base 12, a sliding plate 14 slidably connected to the inner wall of the fixed cylinder 13, a connecting rod 15 fixedly connected to the inner wall of the sliding plate 14, a spring 16 provided between the inner walls of the fixed cylinder 13 and the sliding plate 14, a turntable 17 rotatably connected to the inner wall of the fixed base 12, the bottom end of the plug box body 19 fixedly connected to the top of the turntable 17, one end of the spring 16 connected to the sliding plate 14, the other end of the spring 16 connected to the inner wall of the fixed cylinder 13, and a plurality of plug holes 18 provided on the inner wall of the turntable 17 corresponding to the connecting rod 15.

[0028] Specifically, when the angle of the plug-in box body 19 needs to be adjusted, the user pulls the connecting rod 15 to disengage it from the socket 18. At this time, the user can rotate the plug-in box body 19. The rotation of the plug-in box body 19 drives the turntable 17 to rotate synchronously within the socket 18. When the plug-in box body 19 rotates to a suitable position that meets the actual installation requirements, the user releases the connecting rod 15. At the moment of release, the spring 16 exerts its elastic force, pushing the slide plate 14 out. During the movement of the slide plate 14, it drives the connecting rod 15 to insert into the socket 18, thereby fixing the rotated plug-in box body 19. This design allows users to flexibly adjust the angle of the busbar trunking according to the complex installation environment and the structural characteristics of the equipment it is connected to, effectively solving the installation problems caused by various space limitations and greatly improving the flexibility and adaptability of the installation.

[0029] Working principle: When the plug-in box body 19 is engaged with the busbar trunking body 1, pulling the pull plate 5 causes the limiting strip 6 to move. As the limiting strip 6 moves, the plug rod 3 moves, allowing the plug block 8 and connecting block 10 to be inserted into the connecting box 2. Once inserted, the pull plate 5 is released. When the pull plate 5 is released, the tension spring 7 pulls the limiting plate 4, causing the plug rod 3 to be inserted into the fixing hole 11 for fixation. This makes installation and disassembly more convenient, saving time and labor costs. When disassembly is required, pulling the pull plate 5 causes the plug rod 3 to disengage from the fixing hole 11, and then the plug-in box body 19 can be removed. When the plug block 8 is inserted, the plug connector 9 will be inserted into the busbar trunking body 1. The components work together to move the limiting plate 4, which in turn causes the limiting strip 6 to slide inside the connecting box 2. The limiting strip 6 improves the stability of the limiting plate 4 during movement. When it is necessary to adjust the angle of the plug box body 19, pull the connecting rod 15 to disengage it from the plug hole 18. At this time, rotate the plug box body 19 to drive the turntable 17 to rotate inside the plug hole 18. When the plug box body 19 is rotated to the appropriate position, release the connecting rod 15. When the connecting rod 15 is released, the spring 16 will bounce the slide plate 14. When the slide plate 14 bounces, it will drive the connecting rod 15 to be inserted into the plug hole 18 for fixation. This allows users to flexibly adjust the angle of the busbar according to the actual installation environment and equipment structure to adapt to various space constraints.

[0030] 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.
