[0006] The outer edge of the groove protrudes from the surface of the box body.
[0007] The upper cover is provided with a mounting groove, an operating window is provided in the middle of the mounting groove, the operating window is connected to the box body, a protective cover is provided on the outside of the operating window, one end of the protective cover is hinged to the mounting groove, and the other end is provided with a buckle, the upper cover is provided with a hook that is buckled with the buckle, and a waterproof structure is provided between the operating window and the protective cover.
[0008] The waterproof structure comprises an annular groove arranged on the outer ring of the operating window, and an annular protrusion arranged on the protective cover and matched with the annular groove. A sealing strip is arranged in the annular groove.
[0009] The installation groove is provided with a plurality of screw holes, and the box body is provided with a plurality of screw hole seats matched with the screw holes.
[0010] An anti-skid pad is arranged at the bottom of the box.
[0011] The box body is fixedly provided with power distribution terminals.
[0012] The beneficial effects of the utility model: the utility model forms a groove for installing the waterproof sealing ring by connecting the first mounting part and the second mounting part which are arranged in high and low positions and the connecting part which is arranged in an inclined manner. The waterproof sealing ring is installed in a high and low manner, and its sealing effect is better than that of the traditional simple sealing ring structure. In addition, a sealing protrusion for pressing the waterproof sealing ring is arranged on the upper cover, and the sealing protrusion presses the waterproof sealing ring to form a sealing fit, thereby further enhancing the reliability of the sealing, making it less likely for water to seep into the distribution box, and ensuring the stable operation of the electrical system in the box. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of an embodiment of the utility model;
[0014] Figure 2 It is a structural schematic diagram of another angle of the embodiment of the utility model;
[0015] Figure 3 The figure is a schematic diagram of the explosion structure of an embodiment of the utility model. DETAILED DESCRIPTION
[0016] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0017] like Figure 1-3 As shown, a waterproof distribution box includes a box body 2 and an upper cover 1. The box body 2 and the upper cover 1 are connected by screws. A waterproof rubber ring is arranged between the box body 2 and the upper cover 1. An anti-skid pad 21 is arranged at the bottom of the box body 2 so that the box body is not easy to slide after being fixed. A distribution terminal 12 is fixedly installed in the box body 2 for easy wiring. A groove 3 for installing a waterproof rubber ring is arranged at the upper end of the box body 2. The groove 3 includes a first mounting portion 31 and a second mounting portion 33. The first mounting portion 31 and the second mounting portion 33 are arranged in a high-low manner. The first mounting portion 31 is arranged above the second mounting portion 33. The first mounting portion 31 and the second mounting portion 33 are connected to an inclined connecting portion 32. The high-low manner of installing the waterproof sealing ring has a better sealing effect than the manner of installing the sealing ring on the same plane. The upper cover 1 is provided with a sealing protrusion 11 corresponding to the groove 3 for pressing the waterproof rubber ring and forming a sealing match with the waterproof rubber ring. The sealing protrusion 11 cooperates with the waterproof rubber ring to further enhance the reliability of the seal, so that the distribution box is not prone to water seepage, and the stable operation of the electrical system in the box is guaranteed. In this embodiment, the outer edge of the groove 3 protrudes from the surface of the box body, and the outer edge can be used to protect the box body. Reinforcing ribs can also be provided at the outer edge to improve the strength of the box body.
[0018] In order to facilitate subsequent maintenance and repair after assembly, in this embodiment, the upper cover 1 is provided with a mounting groove 7, an operation window is provided in the middle of the mounting groove 7, the operation window is connected to the box body 2, a protective cover 4 is provided on the outside of the operation window, a pin 41 is provided at one end of the protective cover 4, which is hinged in the pin hole of the mounting groove 7, and a buckle 5 is provided at the other end. The upper cover 1 is provided with a hook 9 that is snap-fitted with the buckle 5, and an operating panel 10 that is easy to open is provided on the outside of the buckle 5. The buckle 5 can be separated from the hook 9 by manually moving the operating panel 10.
[0019] In order to ensure the sealing of the protective cover 4 after closing, a waterproof structure is provided between the operating window and the protective cover 4, including an annular groove provided on the outer circle of the operating window, an annular protrusion 6 provided on the protective cover 4 and matching with the annular groove, a sealing strip is provided in the annular groove, the annular protrusion 6 presses the sealing strip and forms a sealing fit with the sealing strip.
