[0023] See also Figure 2 、 Figure 4 The utility model provides a circuit board for facilitating replacement of panels, comprising a top shell 1 and a bottom shell 4. The inner wall of the bottom shell 4 is fixedly connected to two first connection boxes 10, which are installed on the inner bottom wall of the bottom shell 4. The inner wall of each first connection box 10 is rotatably connected to a bidirectional screw 11, and both ends of each bidirectional screw 11 are fixedly connected to a first connection head 12. By using a suitable tool to connect the first connection head 12, and then rotating the first connection head 12, the first connection head 12 will drive the corresponding bidirectional screw 11 to start rotating. The outer surface of each bidirectional screw 11 is threadedly connected to two first connection plates 13. Specifically, the rotation of the bidirectional screw 11 will drive the corresponding two first connection plates 13 to move in opposite or reverse directions along the corresponding first connection box 10 at the same time.

[0024] In a preferred embodiment, a first slot 14 is provided on the upper surface of each first connecting plate 13, and a first connecting column 15 is inserted into the inner wall of each first slot 14.

A socket 16 is provided on the outer surface of each first connecting column 15, and a connecting block is fixedly connected to the bottom surface of each first connecting column 15. The socket 16 is set on the connecting block, and the outer surface of each first connecting plate 13 is slidably connected to the corresponding first connecting box 10.

[0025] In this embodiment, the inner wall of each first connecting plate 13 is slidably connected to two plug rods 17, and the outer surface of each plug rod 17 is plugged into the corresponding socket 16. Specifically, the first connecting column 15 can be quickly fixed by plugging the plug rod 17 into the corresponding socket 16.

[0026] In this embodiment, the outer surface of each insertion rod 17 is sleeved with a first spring 18, and one end of each first spring 18 close to the corresponding first connecting column 15 is fixedly connected to the corresponding insertion rod 17, and the other end is fixedly connected to the corresponding first connecting plate 13. Specifically, through the setting of the first spring 18, when the insertion rod 17 is pulled, the first spring 18 begins to compress, and when the first connecting column 15 is inserted into the corresponding first slot 14, the insertion rod 17 and the corresponding socket 16 are on the same central axis. At this time, the insertion rod 17 is released, and the first spring 18 will push the corresponding insertion rod 17 into the socket 16 under the action of its rebound force.

[0027] like Figure 1 As shown, the outer surface of the top shell 1 is fixedly connected to two elastic clips 3, and the elastic clips 3 are self-resetting. The outer surface of the bottom shell 4 is fixedly connected to two triangular clips 5, and the inclined surface of the triangular clips 5 faces upward. The outer surface of each elastic clip 3 is clamped with the corresponding triangular clip 5. A heat dissipation groove 2 is provided on the upper surface of the top shell 1. Specifically, by placing the top shell 1 on the bottom shell 4, the elastic clip 3 will be squeezed and contacted with the corresponding triangular clip 5 during this process. At this time, the elastic clip 3 will begin to open until the top shell 1 contacts the bottom shell 4. At this time, the elastic clip 3 will completely pass through the corresponding triangular clip 5, and then the elastic clip 3 will reset under the action of its rebound force, and clamped with the triangular clip 5 to fix the two.

The bottom surface of each second connection plate 7 is fixedly installed with a second connection column 8, and the outer surface of each second connection column 8 is plugged into the corresponding first connection column 15. Specifically, by pulling the second connection plate 7, it can be adjusted according to different widths of the circuit board body 19, and then its second connection column 8 is inserted into the corresponding first connection column 15, so that the circuit board body 19 can be quickly fixed.

[0030] In this embodiment, two second springs 9 are fixedly connected to the inner wall of each second connecting box 6, and two slide grooves are provided inside each second connecting box 6. The second springs 9 are arranged in the corresponding slide grooves. One end of each second spring 9 close to the corresponding second connecting plate 7 is fixedly connected to the corresponding second connecting plate 7. Specifically, by pulling the second connecting plate 7, the second connecting plate 7 can push the corresponding second spring 9 to compress it, and when there is no external force, the second spring 9 will push the corresponding second connecting plate 7 to reset it under the action of its rebound force. The setting of the second spring 9 can make the two second connecting columns 8 balanced in force, thereby increasing the stability of the second connecting box 6 in the top shell 1.
