Technical Field

[0001] This utility model relates to the field of integrated ring main unit technology, specifically to an installation structure for the door of an integrated ring main unit. Background Technology

[0002] The integrated primary and secondary ring main network box integrates primary main circuit equipment with secondary control and protection systems to achieve intelligent management of power distribution equipment, improve power supply reliability and operation and maintenance efficiency. When it is necessary to repair or replace equipment such as circuit breakers, load switches, and surge arresters inside the cabinet, it is necessary to cut off the power, test for voltage, and close the grounding switch before opening the cabinet door. In the existing technology, the cabinet body and the cabinet door are fastened with multiple screws. This connection method is troublesome to disassemble. When replacing or repairing, multiple screws need to be removed one by one to remove the entire cabinet door, which affects the maintenance efficiency. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect that multiple screws need to be removed sequentially during the disassembly of the cabinet door in the prior art, which affects the maintenance progress, and thus provide an installation structure for the cabinet door of the fusion ring network cabinet that is easy to disassemble.

[0004] Therefore, this utility model provides an installation structure for an integrated ring main unit door, including a cabinet body and a door disposed on top of the cabinet body. A positioning structure is provided between the cabinet body and the door. The positioning structure includes a snap-fit ​​extension disposed on one side of the cabinet body or the door and a snap-fit ​​groove disposed on the other side and adapted to the snap-fit ​​extension. The snap-fit ​​extension is disposed on the cabinet body, and the snap-fit ​​groove is disposed on the door. The snap-fit ​​extension includes a connecting end and an extension end arranged in an "L" shape. The extension end can be inserted into the snap-fit ​​groove to connect the door and the cabinet body. A positioning plate for assisting the positioning of the connecting end is provided on the side of the connecting end facing away from the extension end. The positioning plate is embedded inside the cabinet body. The positioning plate is integrally formed with the connecting end and the extension end. The positioning plate and the cabinet body are positioned and connected by fastening nails.

[0005] Furthermore: the snap-fit ​​extension is provided on the cabinet body, and the snap-fit ​​groove is opened on the cabinet door.

[0006] Furthermore: the cabinet door is provided with a lifting plate for users to lift the cabinet door, and an opening for fingers to be inserted is provided between the lifting plate and the cabinet door.

[0007] Furthermore, the pull-out plate is located near the top of the cabinet door.

[0008] The technical solution of this utility model has the following advantages:

[0009] 1. This utility model provides an installation structure for a ring main unit door. A snap-fit ​​extension is provided on one side of the door or cabinet body, arranged along the circumference of the door or cabinet body. A snap-fit ​​groove adapted to the snap-fit ​​extension is provided on the other side. During connection, the door is lifted, the snap-fit ​​extension is inserted into the snap-fit ​​groove, and the grounding interlock component above the cabinet body will hold the door shut, preventing it from being opened. A positioning plate is provided on the side of the connection end facing away from the extension end. This positioning plate is embedded in the cabinet body and has positioning holes. The positioning plate is connected to the cabinet body using fastening nails. This connection effectively fixes the position of the connection end and the extension end, preventing the cabinet body from wobbling when installed above the door. Therefore, the applicant believes that processing the connection end and the extension end from a single steel plate effectively ensures the rigidity of the extension end, thus better preventing breakage of the extension end or door wobbling during connection.

[0010] 2. This utility model provides an installation structure for a fused ring main unit door. A snap-fit ​​extension is disposed on the cabinet body. The snap-fit ​​groove has space for the snap-fit ​​extension to be inserted. The snap-fit ​​extension includes a connecting end and an extending end. During installation, the extending end is fully inserted into the snap-fit ​​groove and abuts against the inner wall of the groove. This allows the cabinet door to be quickly fixed to the cabinet body, effectively improving the efficiency of door disassembly. Attached Figure Description
