Description

Technical Field

[0001] The utility model relates to the technical field of electrical distribution boxes, and particularly relates to a waterproof box which is convenient for maintenance and repair. Background Art

[0002] A distribution box is a box for placing electrical components inside to achieve electrical connection or electrical control. Some outdoor distribution boxes need to have good waterproof and anti-corrosion properties. Therefore, existing outdoor distribution boxes usually adopt plastic waterproof boxes. Existing plastic waterproof boxes generally include a box body and an upper cover. The box body and the upper cover form an accommodation cavity. The box body and the upper cover are connected by screws. A sealing ring is provided between the box body and the upper cover for waterproofing. This structure is inconvenient for maintenance during use. It is necessary to disassemble the screws and the sealing ring, and the operation is cumbersome. After multiple disassembly, the sealing performance is likely to decline, affecting the operation of the electrical system inside the box. Summary of the Invention

[0004] The technical solution provided by the utility model is as follows:

[0005] A waterproof box which is convenient for maintenance and repair, including a box body and an upper cover. The box body and the upper cover are connected by screws. A waterproof rubber ring is provided between the box body and the upper cover. An operation window is provided in the middle of the upper cover. The operation window communicates with the inside of the box body. A protective cover is provided outside the operation window. One end of the protective cover is hinged to the upper cover, and the other end is provided with a buckle. The upper cover is provided with a limit projection that forms a limit fit with the buckle. A waterproof structure is provided between the operation window and the protective cover.

[0006] The waterproof structure includes a groove provided on the outer circle of the operation window, a sealing projection provided on the protective cover and matched with the groove, and a sealing rubber strip is provided in the groove.

[0007] A positioning projection is provided above the operation window, and a positioning groove matched with the positioning projection is provided on the protective cover.

[0008] A convex portion extending downward is provided outside the buckle for facilitating the opening of the protective cover.

[0009] Through holes communicating with each other are provided on the inner side of the limit projection and the buckle.

[0010] A plurality of wire outlet holes are provided on the side and bottom of the box body.

[0011] A power distribution wiring post is fixedly installed inside the box body.

[0012] Mounting seats for fixing are provided at the upper and lower ends of the box body.

[0013] An anti-slip pad is provided at the bottom of the box body.

[0014] Advantages of the present utility model: By providing an operation window and a protective cover in the middle of the upper cover of the waterproof box, and a waterproof structure is arranged between the operation window and the protective cover. When the protective cover is opened, maintenance and repair can be carried out through the operation window without disassembling the screws and waterproof rubber rings. During use, the opening and closing are simple, and multiple openings will not affect the sealing performance of the waterproof box, which is convenient to operate. Description of the Drawings

[0021] The following further describes the embodiments of the present utility model with reference to the drawings.

[0022] As Figure 1-4 shown, a waterproof box convenient for maintenance and repair includes a box body 2 and an upper cover 1. The box body 2 and the upper cover 1 are connected by screws. A power distribution terminal 5 is fixedly installed in the box body 2. The power distribution terminal 5 is fixed in the middle of the box body 2 by screws, which is convenient for wiring. A plurality of wire outlet holes 21 are provided on the side and bottom of the box body 1. Mounting seats 22 for fixing are provided at the upper and lower ends of the box body 2. A non-slip pad 23 is provided at the bottom of the box body 2, so that the box body will not slide after being fixed, ensuring the normal operation of the electrical components in the box.

[0023] A waterproof rubber ring 6 is provided between the box body 2 and the upper cover 1. A concave mounting groove is provided in the middle of the upper cover 1. An operation window 4 is provided in the mounting groove. The operation window 4 communicates with the inside of the box body 2. A protective cover 3 is provided outside the operation window 4. One end of the protective cover 3 is hinged to the mounting groove of the upper cover 1, and a buckle 31 is provided at the other end. The upper cover 1 is provided with a limit protrusion 12 that forms a limit fit with the buckle 31. During normal use, the buckle 31 and the limit protrusion 12 cooperate to prevent the protective cover 3 from accidentally opening without external force intervention, affecting the normal operation of the electrical components in the waterproof box.

[0024] As Figure 5-6As shown, a waterproof structure is provided between the operation window 4 and the protective cover 3, including a groove 13 provided on the outer circle of the operation window 4 and a sealing protrusion 34 provided on the protective cover 3 and mating with the groove 13. A sealing rubber strip is provided in the groove 13. The sealing rubber strip and the sealing protrusion 34 are in interference fit to ensure the sealing performance of the box body when the protective cover 3 is closed, and multiple openings will not affect the sealing performance of the waterproof box, thus ensuring the normal operation of the electrical system inside the box.

[0025] In this embodiment, a positioning protrusion 15 is provided above the operation window 4, and the protective cover 3 is provided with a positioning groove 36 mating with the positioning protrusion 15. When the protective cover 3 is opened and closed, the positioning protrusion 15 and the positioning groove 36 cooperate for positioning, so that the sealing protrusion 34 can accurately engage into the groove 13.

[0026] In this embodiment, a protruding portion 33 extending downward is provided outside the buckle 31. The protruding portion 33 serves as a force application point when the protective cover 3 is opened and closed, which is convenient for operation. A through hole 32 is provided in communication between the inner side of the limit protrusion 12 and the buckle 31, and a lock or bolt can be installed in the through hole 32 to prevent unauthorized personnel from opening the protective cover 3.

[0027] The embodiments should not be construed as limiting the present invention. Any non-creative improvement based on the spirit of the present invention should be regarded as within the protection scope of the present invention.
