[0002] In grounding systems, grounding boxes are important components used in power transmission cable systems. They are widely used in power, railway, urban construction, water conservancy, and rail transit projects. Grounding boxes are used to house grounding wires and protect them.
[0003] In existing grounding boxes, the flange and cover are connected by bolts. While this structure effectively achieves high sealing and waterproofing, it presents a significant challenge during operation and maintenance. Because the flange and cover are secured with more than ten bolts, opening the grounding box cover requires first removing all ten bolts, making the process complex and time-consuming, as is the installation. If the grounding box has a complex six-wire or higher structure, using a bolted connection between the flange and cover would greatly reduce maintenance efficiency and make disassembly and installation even more inconvenient, thus increasing the difficulty of maintenance and labor costs.

[0006] A flip-top grounding box suitable for grounding systems includes a box body and a door; the door and the box body are connected by a hinge structure; the box body is provided with a groove that mates with the door, and the door is provided with a sealing strip; when the door is closed, the box body and the door are sealed together by the sealing strip.
[0007] The working principle of the flip-top grounding box applicable to the above-mentioned grounding system is as follows:
[0008] By incorporating a hinge structure, the door can rotate relative to the cabinet body, enabling flip-top opening or closing. This simple operation allows for quick maintenance, reducing the difficulty and time cost of repairs.
[0009] In a preferred embodiment of this utility model, the box body is provided with a door frame, which is formed by bending a sheet material. The door frame has a bent edge, and when the box door is closed, the sealing strip is sealed to the bent edge. By providing the bent edge, when the box door is closed, the bent edge extends into the sealing strip, causing the sealing strip to deform, thereby ensuring a tight connection between the bent edge and the sealing strip and improving the sealing effect.
