[0002] The low-voltage distribution cabinet is commonly known as the low-voltage switch cabinet, also known as the low-voltage distribution cabinet. It refers to a complete set of electrical devices with AC and DC voltages below 1000V and is a type of complete set of power distribution equipment. It has the characteristics of small volume, light weight, compact structure, convenient installation and use, etc., and is widely used in power users such as power plants, substations, and power departments of industrial and mining enterprises for receiving and distributing electric energy.

[0003] The distribution cabinet is an indispensable power equipment in automatic production. There are multiple groups of relays installed inside it to control the circuit. However, the existing relays are all fixedly installed in the distribution cabinet by screws. During actual use, the distance between adjacent two groups of relays cannot be adjusted. When the circuit is repaired or replaced and a larger or smaller relay needs to be replaced, it will cause the larger relay to be unable to be installed in the original position, and even the circuit inside the distribution cabinet needs to be re-planned, which is time-consuming and laborious and increases the circuit replacement cost. When replacing a smaller relay to the original position, there will be a larger space between adjacent relays, reducing the installation quantity of the relays and causing waste of space.

[0004] Therefore, a low-voltage distribution cabinet is needed to solve the above-mentioned problems. Content of the Utility Model

A connecting board is inserted outside the plug board. A sliding assembly is arranged on the inner wall of the connecting board. A relay is installed outside the sliding assembly. The sliding assembly is used to drive the relay to move on the connecting board.

[0007] Further, a slot adapted to the size of the plug board is opened on the inner wall of the connecting board. The plug board is inserted into the inner side of the slot, and a fixing block is inserted at the end of the plug board. The fixing block is used to fix the connecting board.

[0008] Further, a T-shaped sliding slot is opened on the inner wall of the connecting board, and insertion holes are evenly opened on the inner wall of the connecting board and inside the T-shaped sliding slot.

[0009] Furthermore, the sliding assembly includes a plug rod, a connecting block, and a T-shaped slider. The T-shaped slider is slidably connected to the inner side of the T-shaped chute. A connecting block is fixedly connected to the top of the T-shaped slider, and a plug rod is inserted into the inner wall of the connecting block.

[0010] Furthermore, the connecting block and the relay are fixedly installed by screws, and the T-shaped slider can drive the connecting block to slide along the outer side of the connecting plate.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The embodiment is Figures 1-4 given. The present utility model discloses a low-voltage power distribution cabinet, including a cabinet body 1, a cabinet door 2 and heat dissipation holes 3. The cabinet door 2 is hinged to the outside of the cabinet body 1, and heat dissipation holes 3 are opened on the side wall of the cabinet body 1. A wire slot 4 is opened on the inner wall of the cabinet body 1 for the installation of wires. An insertion plate 7 is fixedly connected to the inner side of the cabinet body 1. A connection plate 5 is inserted outside the insertion plate 7. A slot 11 adapted to the size of the insertion plate 7 is opened on the inner wall of the connection plate 5. The insertion plate 7 is inserted into the inside of the slot 11, and a fixing block 8 is inserted at the end of the insertion plate 7. The fixing block 8 is used to fix the connection plate 5;

[0022] A sliding assembly is arranged on the inner wall of the connection plate 5, and a relay 6 is installed outside the sliding assembly. The sliding assembly is used to drive the relay 6 to move on the connection plate 5;

[0023] The sliding assembly includes an insertion rod 12, a connection block 13 and a T-shaped slider 14. The T-shaped slider 14 is slidably connected to the inside of the T-shaped chute 9. The connection block 13 is fixedly connected to the top of the T-shaped slider 14, and the insertion rod 12 is inserted into the inner wall of the connection block 13;

[0024] Specifically, the connection block 13 and the relay 6 are fixedly installed by screws, and the T-shaped slider 14 can drive the connection block 13 to slide along the outside of the connection plate 5;

[0025] Specifically, the size of the insertion rod 12 is adapted to the size of the insertion hole 10, and the insertion rod 12 can be inserted into the inside of the insertion hole 10 to fix the connection block 13;

[0026] Specifically, a T-shaped chute 9 is opened on the inner wall of the connection plate 5, and insertion holes 10 are evenly opened on the inner wall of the connection plate 5 and inside the T-shaped chute 9.

[0027] Working principle: When the power distribution cabinet is in use, the relay 6 can be installed on the sliding assembly inside the connection plate 5, and the wires can be bundled and placed into the wire slot 4 for wire routing;

[0028] When the relay 6 needs to be replaced, the relay 6 can be removed from the connection block 13 and a new relay 6 can be installed on the connection block 13. By pulling out the insertion rod 12 on the inner wall of the connection block 13 from the jack 10, the limit on the connection block 13 can be released. At this moment, by sliding the T-shaped slider 14 at the bottom of the connection block 13 along the inner side of the T-shaped chute 9, the connection block 13 can slide on the outside of the connection plate 5, thereby adjusting the corresponding position of the relay 6. After the adjustment is completed, by inserting the insertion rod 12 into the inner side of the jack 10 again, the connection block 13 can be fixed, so that the relay 6 is fixed on the outside of the connection plate 5;

[0029] Before and after replacing the relay 6, by pulling out the fixing block 8 from the insertion plate 7, the connection plate 5 can be slid out along the outside of the insertion plate 7, and then the connection plate 5 can be removed. The connection plate 5 can be inserted onto the adjacent upper and lower insertion plates 7, and then the distance between the adjacent upper and lower connection plates 5 can be adjusted to adapt to the size of the relay 6 after replacement.

[0030] In the above process, by sliding the T-shaped slider 14 along the T-shaped chute 9, the lateral position of the relay 6 can be adjusted. By inserting and separating the connection plate 5 and the insertion plate 7, the vertical position of the relay 6 can be adjusted, realizing the adjustment of the distance between two adjacent groups of relays. When a larger or smaller relay needs to be replaced, it is ensured that the larger relay can be installed in the original position without re-planning the circuits in the power distribution cabinet, saving time and effort and reducing the circuit replacement cost. When ensuring that a smaller relay is replaced in the original position, the space between adjacent relays can be adjusted, increasing the installation quantity of the relays and saving space.
