[0002] A distribution cabinet is an electrical device used for power distribution and control, usually used in industrial, commercial and residential places, etc. Its main function is to receive and distribute electric energy and protect electrical equipment from faults such as overload, short circuit and leakage.

[0003] In the prior art, the electrical equipment in the distribution cabinet is usually connected to the external lines through the outgoing line holes on the cabinet body. However, the sealing performance of the positions of the outgoing line holes of the wires is poor, so that dust in the external air may enter the interior of the distribution cabinet through the gaps between the outgoing line holes and the wires. Furthermore, it may cause dust to adhere to the electrical equipment in the distribution cabinet. If the electrical equipment in the distribution cabinet is not cleaned in time, it may affect the heat dissipation effect of the electrical equipment, thus possibly causing the electrical equipment to have an overheat short circuit, and further affecting the normal operation of the electrical equipment in the distribution cabinet. Therefore, a sealing device for the incoming and outgoing lines of a distribution cabinet is needed. Summary of the Utility Model

The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0026] Refer to Figure 1-7, in an embodiment of the utility model, a sealing device for the incoming and outgoing lines of a distribution cabinet includes a distribution cabinet 1, on which a plurality of electric wires 2 are arranged. A connecting plate 3 is fixedly connected to the rear surface of the distribution cabinet 1, and two connecting blocks 4 are fixedly connected to the rear surface of the connecting plate 3. First limiting rods 5 are fixedly connected to the inner surfaces of the two connecting blocks 4. Two first sliders 6 are slidably connected to the outer surfaces of the two first limiting rods 5. The corresponding two first sliders 6 are fixedly connected to the same movable plate 7. A plurality of upper sealing rings 9 are movably connected to the inner surface of one of the movable plates 7, and a plurality of lower sealing rings 10 are movably connected to the inner surface of the other movable plate 7. Plug blocks 8 are fixedly connected to both the upper sealing rings 9 and the lower sealing rings 10. The side surfaces of the upper sealing rings 9 and the lower sealing rings 10 are in contact with the electric wires 2, the front surfaces of the upper sealing rings 9 and the lower sealing rings 10 are in contact with the connecting plate 3, and the lower surface of the upper sealing ring 9 is in contact with the lower sealing ring 10. A first wire outlet hole 11 is formed in the distribution cabinet 1, and a second wire outlet hole 12 is formed in the connecting plate 3. The first wire outlet hole 11 is communicated with the second wire outlet hole 12. The electric wires 2 respectively penetrate through the first wire outlet hole 11 and the second wire outlet hole 12. A docking groove 13 is formed in the connecting plate 3, and the outer surface of the plug block 8 is movably connected to the docking groove 13. A first spring 14 is slidably sleeved on the outer surface of the first limiting rod 5. One end of the first spring 14 is fixedly connected to the side surface of the first slider 6, and the end of the first spring 14 far from the first slider 6 is fixedly connected to the side inner wall of the connecting block 4. The outer surface of the first slider 6 is slidably connected to the connecting block 4.

[0027] Two second limiting rods 15 are fixedly connected to the inner surfaces of the two movable plates 7. Four second sliders 16 are slidably connected to the outer surfaces of the four second limiting rods 15. The corresponding two second sliders 16 are fixedly connected to the same fixed rod 17. The outer surface of the second slider 16 is slidably connected to the movable plate 7. A second spring 18 is slidably sleeved on the outer surface of the second limiting rod 15. One end of the second spring 18 is fixedly connected to the side surface of the second slider 16, and the end of the second spring 18 far from the second slider 16 is fixedly connected to the side inner wall of the movable plate 7. The front surface of the fixed rod 17 is in contact with the plug block 8.

[0028] Working principle: Under the action of the upper sealing ring 9 and the lower sealing ring 10, the first wire outlet hole 11 and the second wire outlet hole 12 can be blocked. At the same time, because the upper sealing ring 9 and the lower sealing ring 10 have good sealing effects, the sealing effects between the connecting plate 3 and the upper sealing ring 9 and the lower sealing ring 10, as well as between the wire 2 and the upper sealing ring 9 and the lower sealing ring 10 can be improved. Furthermore, it can prevent dust in the external air from entering the interior of the power distribution cabinet 1 through the gaps between the first wire outlet hole 11, the second wire outlet hole 12 and the wire 2. When the upper sealing ring 9 needs to be replaced after a period of use, by pulling the fixed rod 17, the moving fixed rod 17 can drive the second slider 16 to move horizontally on the second limiting rod 15, so that the moving second slider 16 squeezes the second spring 18 on the inner wall of the movable plate 7, and then the second spring 18 is in a taut state. When the moving fixed rod 17 no longer contacts the insertion block 8, the fixation of the insertion block 8 is released, thus releasing the fixation of the upper sealing ring 9, and then the upper sealing ring 9 can be removed from the movable plate 7 for replacement. Then, by pulling the movable plate 7, the moving movable plate 7 can drive the first slider 6 to move horizontally on the first limiting rod 5, so that the moving first limiting rod 5 squeezes the first spring 14 on the inner wall of the connecting block 4, and then the first spring 14 is in a taut state. And the moving movable plate 7 will simultaneously drive the insertion block 8, the upper sealing ring 9, the lower sealing ring 10, the second limiting rod 15, the second slider 16, the fixed rod 17 and the second spring 18 to move. When the moving upper sealing ring 9 no longer contacts the wire 2, it is convenient to remove the upper sealing ring 9 from the movable plate 7. Then, by pulling the upper sealing ring 9, the upper sealing ring 9 can be taken out from the movable plate 7. Then, insert the insertion block 8 on the new upper sealing ring 9 into the docking groove 13, and the preliminary connection between the upper sealing ring 9 and the movable plate 7 can be realized. Then, release the pulled fixed rod 17, so that the second spring 18 is no longer restricted by the pulling force and rebounds. Then, the rebounding second spring 18 drives the second slider 16 and the fixed rod 17 to move. When the moving fixed rod 17 contacts the insertion block 8, the fixation of the insertion block 8 is realized, and at the same time, the fixation between the movable plate 7 and the upper sealing ring 9 is completed. Then, release the pulled movable plate 7, so that the first spring 14 is no longer restricted by the pulling force and rebounds. Then, the rebounding first spring 14 drives the first slider 6, the movable plate 7, the insertion block 8 and the upper sealing ring 9 to move. When the moving upper sealing ring 9 contacts the wire 2, perform the above operations again, so that the lower sealing ring 10 can be replaced. When the replacement of the lower sealing ring 10 is completed and it contacts the wire 2, the blocking and sealing of the first wire outlet hole 11 and the second wire outlet hole 12 are realized.

However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
