Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a segmented busbar trunking system that is easy to maintain, provided by this utility model; Figure 2 for Figure 1 The diagram shows the structural schematic of the shell. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the shell. Figure 4 for Figure 2 The enlarged schematic diagram of section A is shown. A segmented busbar trunking system that is easy to maintain includes: a housing 1, a cover 2, a limiting device 3, and a fixing device 4;

[0029] The cover 2 is disposed on the surface of the housing 1;

[0030] The limiting device 3 includes multiple mounting slots 31, multiple limiting slots 32, and multiple limiting blocks 33. The multiple mounting slots 31 are all opened inside the housing 1. One end of each of the multiple limiting slots 32 is respectively disposed at one end of each of the multiple mounting slots 31. The multiple limiting blocks 33 are respectively slidably connected inside the multiple limiting slots 32.

[0031] The inside of the cover 2 is provided with a fixing device 4, which is used to limit the position of the cover 2.

[0032] The multiple limiting blocks 33 are all T-shaped blocks, and one end of each is fixedly connected to both sides of the surface of the shell cover 2. They are used to limit the distance between the shell 1 and the shell cover 2 after the multiple limiting blocks 33 move from the inside of the multiple mounting grooves 31 to the inside of the multiple limiting grooves 32.

[0033] Multiple limiting grooves 32 are formed inside the housing 1.

[0034] The fixing device 4 is a bolt. Both the housing 1 and the cover 2 have two threaded holes that are compatible with the bolt. When the bolt is installed into the threaded hole, it is used to limit the movement between the housing 1 and the cover 2.

[0035] The fixing device 4 includes a fixing groove 41, two fixing blocks 42, a fixing spring 43, and two fixing pins 44. The fixing groove 41 is opened inside the shell cover 2. The two fixing blocks 42 are slidably connected inside the fixing groove 41. The fixing spring 43 is disposed inside the fixing groove 41 and located between the two fixing blocks 42. One end of each of the two fixing pins 44 is fixedly connected to one side of the two fixing blocks 42.

[0036] The fixing device 4 also includes two fixing holes 45, both of which are located inside the housing 1.

[0037] Two fixing pins 44 are slidably connected to the inside of two fixing holes 45 respectively, and one side of the two fixing pins 44 is inclined, so that after the fixing pins 44 move to one side and contact one side of the housing 1, the two fixing pins 44 automatically move to one side.

[0038] When in use, as the cover 2 moves to one side, one side of the two fixing pins 44 contacts the housing 1, and the two fixing pins 44 move to one side along the inclined plane, thereby driving the two fixing blocks 42 to move towards the middle inside the fixing groove 41, while squeezing the fixing spring 43.

[0039] When the cover 2 moves to a suitable position, the fixing spring 43 pushes the two fixing blocks 42 to move to both sides inside the fixing groove 41, thereby causing the two fixing pins 44 to move to both sides and enter the two fixing holes 45 respectively, thus limiting the cover 2.

[0040] The working principle of the segmented busbar trunking that is easy to maintain provided by this utility model is as follows:

[0041] In use, after inserting the multiple limiting blocks 33 at the bottom of the cover 2 into the multiple mounting slots 31, the cover 2 is moved to one side, thereby causing the multiple limiting blocks 33 to move to one side inside the multiple mounting slots 31 and into the multiple limiting slots 32. After moving to the appropriate position, they are limited by the fixing device 4.

[0042] Compared with related technologies, the segmented busbar trunking provided by this utility model, which is easy to maintain, has the following advantages:

[0043] This utility model provides a segmented busbar trunking that is easy to maintain. After the cover 2 and the housing 1 are combined and moved to a suitable position on one side, they are initially limited by the limiting device 3 and then limited by the fixing device 4. This makes it convenient and quick to install and disassemble the housing 1 and the cover 2, which facilitates subsequent maintenance work.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application which provides a segmented busbar trunking system that is easy to maintain, the second embodiment of this application proposes another segmented busbar trunking system that is also easy to maintain. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the second embodiment of this application provides a segmented busbar trunking that is easy to maintain.

The multiple moving slots 51 are all opened inside the housing 1, and the multiple moving blocks 52 are slidably connected to the interior of the multiple moving slots 51.

[0047] Two movable frames 6 are fixedly connected to one side of the plurality of movable blocks 52. Each of the two movable frames 6 is provided with a sealing element 7 and a fixing element 8.

[0048] One side of each of the multiple movable blocks 52 is fixedly connected to one side of the two movable frames 6, which is used to limit the movable frames 6 while allowing the movable frames 6 to move to one side.

[0049] The sealing element 7 is a sealing ring, and the surface of the sealing ring is fixedly installed inside the movable frame 6.

[0050] The sealing element 7 is an airbag, used to seal the two ends of the conductive busbar and the housing 1 after the two sealing elements 7 are combined.

[0051] The fixing element 8 is a bolt, and the interior of both the movable frame 6 and the housing 1 is provided with threaded holes that are compatible with the bolt.

[0052] After the movable frame 6 is moved to the appropriate position, it is limited by installing bolts into the threaded holes.

[0053] The working principle of the segmented busbar trunking that is easy to maintain provided by this utility model is as follows:

[0054] In use, after the busbar trunking is assembled with the curved arm, the moving frame 6 is moved to one side by loosening the fixing part 8, thereby driving the two moving blocks 52 to move to one side inside the two moving slots 51 respectively.

[0055] After the two movable frames 6 are combined, the two seals 7 are combined, and then the fixing parts 8 are installed.

[0056] Compared with related technologies, the segmented busbar trunking provided by this utility model, which is easy to maintain, has the following advantages:

[0057] This utility model provides a segmented busbar trunking that is easy to maintain. By using a moving device 5 in conjunction with a moving frame 6 and a fixing component 8, after the busbar trunking is assembled with a bent arm, the two sealing components 7 are combined to seal the two ends of the conductive busbar with the housing 1.
