Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a ring network cabinet which is convenient for connecting adjacent cabinets. Background Art

[0002] Ring main unit is a group of electrical equipment (high voltage switchgear) installed in a metal or non-metallic insulated cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses, which have the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers. Ring main units are usually assembled and connected to make assembled interval ring main unit.

[0003] However, when the existing ring network cabinet is connected and assembled between two adjacent cabinets, the two adjacent side panels between the two cabinets are usually fixed by fixing bolts. However, this connection and fixing method requires operation inside the cabinet of the ring network cabinet during connection and disassembly, which results in not only opening the ring network cabinet during operation, but also a relatively small space inside the cabinet, which makes it very inconvenient for the staff to operate, and thus leads to low efficiency when connecting or disassembling two adjacent ring network cabinets. Therefore, we make improvements on this and propose a ring network cabinet that is easy to connect adjacent cabinets. Utility Model Content

[0004] The utility model provides a ring network cabinet which is convenient for connecting adjacent cabinets, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A ring network cabinet that is convenient for connecting adjacent cabinets, includes a cabinet, wherein the front and rear of one side of the cabinet are provided with connecting strips, the front and rear of the other side of the cabinet are provided with connecting plates, one side of the connecting strip is provided with a cover plate, the top and bottom of the cover plate are provided with grooves, and plug rods are movably inserted in the grooves, one end of the plug rod is provided with a block, the block card is embedded in the groove, a spring is mounted on the plug rod, and the end of the plug rod away from the block is provided with a limit block, the top and bottom of the connecting strip are provided with an accommodating cavity, one end of the accommodating cavity is provided with a through hole, the top and bottom of the connecting plate are provided with a socket, the end of the plug rod away from the block is movably arranged in the accommodating cavity, and the end of the plug rod away from the block passes through the through hole and is inserted into the socket.

[0007] Preferably, two ends of the spring are respectively against the cover plate and the limit block.

[0008] Preferably, a pull ring is rotatably provided at the front end of the stopper.

[0009] Beneficial Effects

[0010] The above one or more technical solutions in a ring main unit that facilitates connection of adjacent cabinets provided by the embodiment of the utility model have at least one of the following technical effects:

[0011] Through the above technical scheme, the utility model, when connecting two adjacent cabinets, overlaps the connecting plate on one cabinet with the connecting strip on the other cabinet, then the through hole on the connecting strip overlaps the jack on the connecting plate, then the plug rod is inserted into the jack, and the connection between the two adjacent ring network cabinets can be completed. When connecting the two adjacent cabinets, the pull ring at the front end of the stopper is turned out, and the pull ring is pulled to pull the plug rod out of the jack to cancel the fixation between the connecting plate and the connecting strip, and the connecting plate and the connecting strip can be separated, and the disassembly between the two adjacent ring network cabinets can be completed. The utility model effectively improves the efficiency of connecting and disassembling between the two adjacent ring network cabinets, is convenient and simple to operate, and reduces the workload of the staff.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-7 As shown, it is a structural schematic diagram of a ring main unit that is convenient for connecting adjacent cabinets in a preferred embodiment of the utility model;

[0025] In this embodiment, a cabinet body 1 is included, and a connecting strip 2 is welded at the front and rear of one side of the cabinet body 1, and a connecting plate 3 is welded at the front and rear of the other side of the cabinet body 1. The connecting plate 3 has the same length and width as the connecting strip 2. A cover plate 4 is fixed to one side of the connecting strip 2 by screws, and grooves 5 are provided at the top and bottom of the cover plate 4. The grooves 5 are circular structures, and rods 6 are movably inserted in the grooves 5. The rods 6 are cylindrical structures, and a stopper 7 is provided at one end of the rod 6. The stopper 7 is a cylindrical structure, and the stopper 7 is embedded in the groove 5. A spring 8 is mounted on the rod 6, and a limit block 9 is provided at the end of the rod 6 away from the stopper 7. The limit block 9 is used to limit the spring 8. The top and bottom of the connecting strip 2 are both provided with a accommodating cavity 10, and the accommodating cavity 10 is arranged in conjunction with the plug rod 6. A through hole 11 is arranged at one end of the accommodating cavity 10, and the through hole 11 is used to pass the plug rod 6. The top and bottom of the connecting plate 3 are both provided with a plug hole 12, and the plug hole 12 is arranged in conjunction with the plug rod 6. The end of the plug rod 6 away from the block 7 is movably arranged in the accommodating cavity 10, and the end of the plug rod 6 away from the block 7 passes through the through hole 11 and is inserted into the plug hole 12. The connecting plate 3 and the connecting strip 2 are fixed by inserting the plug rod 6 into the plug hole 12, thereby completing the connection and fixation between the two adjacent cabinets 1.

[0026] In this embodiment, the two ends of the spring 8 are respectively abutted against the cover plate 4 and the limit block 9, and the spring 8 provides elastic potential energy to the insertion rod 6. When the insertion rod 6 is inserted into the socket 12, the spring provides a retaining force to the insertion rod 6 to prevent the insertion rod 6 from falling out of the socket 12.

[0027] In this embodiment, a pull ring 13 is rotatably provided at the front end of the stopper 7. The staff can pull the insertion rod 6 through the pull ring 13 to remove the insertion rod 6 from the insertion hole 12. The rotation structure of the pull ring 13 allows the pull ring 13 to be rotated and folded to reduce space occupancy.
