[0024] like Figure 1-5As shown, a bus duct plug-in box plug-in structure of the present embodiment comprises a positioning plate 1 and a bottom plate 2, the positioning plate 1 is fixed on the bus duct 6, and a sleeve hole 15 is provided on the positioning plate 1, so that the circuit plug-in board on the bus duct 6 can protrude above the positioning plate 1, and a positioning block 11 is fixedly connected at the four corners of the top of the bottom plate 2, and a positioning groove 12 and a groove 13 are provided on one side of the positioning block 11, and the groove 13 is located above the positioning groove 12, and a limiting groove 14 is provided on the top of the groove 13, and a notch 21 is provided at the four corners of the bottom plate 2, and a storage groove 1 22 and a storage groove 23 are provided on one side of the notch 21, and the storage groove 23 is located above the storage groove 1 22, and the storage groove 23 is located above the storage groove 1 22. Slot one 22 corresponds to the position of the positioning slot 12, and storage slot two 23 corresponds to the position of the groove 13. A connecting slot 24 is provided between storage slot one 22 and storage slot two 23. The interior of the connecting slot 24 is rotatably connected with a positioning cylinder 3. The bottom of the positioning cylinder 3 is fixedly connected with a fixing plate 31, and the fixing plate 31 is located in the storage slot one 22. A transmission slot 32 is provided at the top of the positioning cylinder 3. A spring 33 is provided in the transmission slot 32. A transmission block 4 is inserted in the transmission slot 32. The transmission block 4 can move up and down in the transmission slot 32. The spring 33 is used to support the transmission block 4. The top of the transmission block 4 is fixedly connected with a limiting plate 41, and the limiting plate 41 is located inside the storage slot two 23.

[0025] Embodiment 1: A connecting groove 42 is provided at the top of the limiting plate 41 at a position corresponding to the positioning tube 3, and a hole groove 25 is provided at the top of the base plate 2 at a position corresponding to the connecting groove 42. The shape of the connecting groove 42 is a cross or a hexagon. A screwdriver or a hexagonal wrench can be used to penetrate the hole groove 25 and insert into the connecting groove 42, and then the limiting plate 41 is pressed down to make the limiting plate 41 correspond to the groove 13, and then the limiting plate 41 is rotated ninety degrees to make the fixing plate 31 and the limiting plate 41 rotate to the positioning groove 12 and the groove 13 respectively, and the screwdriver or hexagonal wrench is pulled out, and the spring 33 rebounds to lift the transmission block 4, and the limiting plate 41 rises and enters the limiting groove 14, so that the limiting plate 41 and the fixing plate 31 cannot rotate, thereby fixing the base plate 2 on the positioning plate 1.

The shape of the hole groove 25 is L-shaped, and the thickness of the receiving groove 23 is greater than or equal to the sum of the thicknesses of the limiting plate 41 and the rotating rod 5, so that the positioning shaft 51 and the driving shaft 52 can pass through the hole groove 25 and be inserted into the connecting groove 42 and the driving groove 43, and the rotating rod 5 is pressed down, and the rotating rod 5 can enter the receiving groove 23, then the rotating rod 5 can be rotated, and the top of the rotating rod 5 corresponding to the positioning shaft 51 is fixedly connected with a rotating shaft 53, and the top of the rotating shaft 53 is fixedly connected with a handle 54, and the rotating rod 5 can be rotated by the handle 54.

[0028] The working principle of the utility model is as follows: when in use, the fixing plate 31 and the limiting plate 41 are rotated to the receiving groove 1 22 and the receiving groove 23, and then the bottom plate 2 is placed on the positioning plate 1, so that the positioning shaft 51 and the driving shaft 52 pass through the hole groove 25 and are inserted into the connecting groove 42 and the driving groove 43. At this time, the rotating rod 5 is inserted into the L-shaped hole groove 25, and then the limiting plate 41 is pressed down to make the rotating rod 5 enter the receiving groove 23. At this time, the limiting plate 41 and the fixing plate 31 are rotated so that the fixing plate 31 is inserted into the positioning groove 12, and the limiting plate 41 is inserted into the groove 13, and then the rotating rod 5 is pulled out to complete the fixation.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Press down the limit plate 41 to make the limit plate 41 correspond to the groove 13, then rotate the limit plate 41 90 degrees to make the fixed plate 31 and the limit plate 41 rotate to the positioning groove 12 and the groove 13 respectively, loosen the limit plate 41, the spring 33 rebounds to lift the transmission block 4, and the limit plate 41 rises into the limit groove 14, so that the limit plate 41 and the fixed plate 31 cannot rotate, thereby fixing the bottom plate 2 on the positioning plate 1. When disassembling, it is necessary to use relevant tools to perform reverse operation for disassembly, which improves safety while ensuring easy disassembly and assembly.

[0031] 2. By providing a circular connecting groove 42, and cooperating with the driving groove 43 and the L-shaped hole groove 25, common tools inserted into the circular connecting groove 42 cannot rotate the limit plate 41 and the fixing plate 31, and can only be disassembled using specific tools, thereby further improving safety.
