[0027] Reference Figures 1 to 6 In one embodiment of this utility model, a waterproof box for a circuit breaker includes:

[0028] The box 100 is cubic in shape. The bottom of the box 100 is a base plate 110 and the top is an opening 120. The circuit breaker is installed inside the box 100.

[0029] The inner cover plate 200 is hinged at one end in the length direction to the top end of the box body 100 in the length direction. The inner cover plate 200 is provided with a window 210, wherein when the inner cover plate 200 is combined with the box body 100, the window 210 corresponds to the circuit breaker.

[0030] The outer cover plate 300 has one end hinged to the top end of the box body 100 along its length, and the other end of the outer cover plate 300 along its length is snap-fitted to the other end of the top end of the box body 100 along its length. When the outer cover plate 300 is combined with the box body 100, the outer cover plate 300 encloses the inner cover plate 200 inside the box body 100.

[0031] In the existing technology, the window structure is small in size and inconvenient to process, and it is also inconvenient to operate the circuit breaker through the window structure. Furthermore, the installation or maintenance of the circuit breaker requires the entire outer cover to be removed.

[0032] The waterproof box for the circuit breaker provided by this utility model includes a box body 100, an inner cover plate 200, and an outer cover plate 300.

[0033] The box 100 is generally cubic in shape. The bottom of the box 100 is a base plate 110 and the top is an opening 120. A circuit breaker is installed inside the box 100, and through holes can be provided at corresponding positions in the box 100 to provide a basis for the electrical connection of the circuit breaker.

[0034] One end of the inner cover plate 200 is hinged to one end of the top of the box body 100 along its length. The hinge structure between the inner cover plate 200 and the box body 100 is preferably a simple structure, for example, the inner cover plate 200 has hinge protrusions 230 at both ends in its width direction, and the box body 100 has hinge grooves 121 corresponding to the positions of the hinge protrusions 230, thus forming a hinge between the inner cover plate 200 and the box body 100. A window 210 is provided on the inner cover plate 200. When the inner cover plate 200 is engaged with the box body 100, the window 210 corresponds to a circuit breaker, providing a spatial basis for operating the circuit breaker without lowering the inner cover plate 200.

[0035] One end of the outer cover plate 300 is hinged to one end of the top of the box body 100 along its length. For example, multiple mounting rings are provided at corresponding positions on the box body 100 and the outer cover plate 300, and a hinge shaft is used to achieve a hinged fit between the box body 100 and the outer cover plate 300. The other end of the outer cover plate 300 along its length is snap-fitted to the other end of the top of the box body 100. It is relatively simple to open the outer cover plate 300 from the box body 100 by hinged one end to the opening 120 and snap-fitting the other end to the opening 120. For example, an elastic piece is provided on the outer cover plate 300, and a fixing groove is provided at a corresponding position on the opening 120, and the snap-fit ​​connection is achieved by the combination of the elastic piece and the fixing groove. When the outer cover plate 300 is engaged with the box body 100, the outer cover plate 300 closes the inner cover plate 200 within the box body 100.

[0036] During use, the circuit breaker's waterproof box is erected with one end of the box body 100mm in length at the bottom and the other end of the box body 100mm in length at the top.

[0037] During installation, the circuit breaker is first installed inside the housing 100, and then the inner cover 200 and outer cover 300 are installed sequentially. During operation, the outer cover 300 is opened, and the circuit breaker is operated through the window 210 on the inner cover 200. During maintenance, the outer cover 300 is opened, and then the inner cover 200 is opened to complete the maintenance of the circuit breaker.

[0038] In summary, one end of the inner cover plate 200 is hinged to the top of the box 100 along its length, and a window 210 is provided on the inner cover plate 200. One end of the outer cover plate 300 is hinged to the opening 120, and the other end is snapped into the opening 120, thus making it relatively simple to open the outer cover plate 300 from the box 100. The simplified structure of the inner cover plate 200 and the outer cover plate 300 facilitates production. When the outer cover plate 300 is combined with the box 100, it closes the inner cover plate 200 within the box 100. During operation, the outer cover plate 300 is opened, and the circuit breaker is operated through the window 210 on the inner cover plate 200, which is quick and convenient. During maintenance, both the outer cover plate 300 and the inner cover plate 200 are opened to complete the maintenance of the circuit breaker, eliminating the need for disassembly of the outer cover plate 300 and the inner cover plate 200, thus offering the advantages of simplicity and speed.

[0039] Reference Figures 1 to 6 In one embodiment, a handle piece 220 is provided at the other end of the inner cover plate 200 along its length. When the inner cover plate 200 is combined with the box body 100, the handle piece 220 and the box body 100 are locked together.

[0040] In the aforementioned embodiments, the connection state between the other end of the inner cover plate 200 along its length and the box body 100 is not restricted; the inner cover plate 200 can be clamped by the outer cover plate 300 and the internal circuit breaker. In this embodiment, a handle piece 220 is provided on the inner cover plate 200. The inner cover plate 200 can be operated through the handle piece 220, and at the same time, the handle piece 220 is used to form a snap-fit ​​fixation with the box body 100, achieving convenient and efficient use.

[0041] Reference Figures 1 to 6 In one embodiment, the inner cover plate 200 has hinge protrusions 230 at both ends in the width direction, and the box body 100 is provided with hinge grooves 121 corresponding to the positions of the hinge protrusions 230, so that the inner cover plate 200 and the box body 100 are hinged.

[0042] In this embodiment, a convenient hinge structure is provided, which has the advantages of simple processing and easy assembly and disassembly.

[0043] Reference Figures 3 to 6 In one embodiment, a protrusion 122 is provided on the inner wall of one end of the box body 100 along its length. After the inner cover plate 200 is turned outward by 80 to 100 degrees, the protrusion 122 abuts against and restricts the rotation of the inner cover plate 200.

[0044] In the aforementioned embodiment, the rotation angle of the inner cover 200 is limited by the protrusion 122, thereby reducing the possibility of accidental damage to the inner cover 200 during use, while the folded-down inner cover 200 can also serve as a storage area.

[0045] Reference Figure 4 In one embodiment, a magnetic element 111 is fixed on the base plate 110.

[0046] In this embodiment, the magnetic component 111 can generate a magnetic interaction with external non-diamagnetic materials, thereby completely fixing the waterproof box or assisting in fixing the waterproof box. The magnetic component 111 can be a strong magnetic material such as a rare-earth permanent magnet, thus providing a strong magnetic effect.

[0047] Reference Figure 4 In one embodiment, a slot 112 extending through the width of the base plate 110 is fixed on the base plate 110.

[0048] In this embodiment, the box 100 can be combined with the external fixing plate through the setting of the slot 112.

[0049] Reference Figure 4 In one embodiment, a pin 113 is inserted into the base plate 110 along its length, and the pin 113 passes into the slot 112.

[0050] In this embodiment, the fixing effect is achieved by the pin 113. At this time, the shape of the slot 112 can be more flexible, and the locking effect is mainly achieved by the pin 113. The pin 113 can be elastically fixed to the base plate 110.

[0051] Reference Figure 4 In one embodiment, the base plate 110 is provided with a mounting groove 114.

[0052] In this embodiment, the mounting groove 114 can be connected to an external mounting base (such as a hook or nail) to completely fix the waterproof box or assist in fixing the waterproof box. The shape of the mounting groove 114 is not limited, as long as it can achieve the mounting.

[0053] Reference Figure 4 In one embodiment, the base plate 110 is provided with fixing holes 115 on its outer periphery.

[0054] In this embodiment, the box 100 is fixed through the fixing hole 115, for example, by using a fixing nail to pass through the fixing hole 115 and connect it to a fixing base (such as a wall).

[0055] In one embodiment, the box body 100, the inner cover plate 200, and the outer cover plate 300 are all made of polymers.

[0056] In this embodiment, the materials of the box body 100, inner cover plate 200 and outer cover plate 300 are commonly used polycarbonate, nylon 6 or ABS, etc. The specific material selection needs to take into account flame retardancy, temperature resistance, mechanical strength and electrical insulation performance.

[0057] In summary, the waterproof box for the circuit breaker provided by this utility model has an inner cover plate 200 hinged at one end along its length to the top of the box body 100 along its length, and a window 210 provided on the inner cover plate 200; one end of the outer cover plate 300 is hinged to the opening 120, and the other end is snapped into the opening 120, thus making the process of opening the outer cover plate 300 from the box body 100 relatively simple; the structure of the inner cover plate 200 and the outer cover plate 300 is simplified, and production is convenient; When the cover plate 300 is combined with the box body 100, the outer cover plate 300 closes the inner cover plate 200 within the box body 100. During operation, the outer cover plate 300 is opened, and the circuit breaker is operated through the window 210 on the inner cover plate 200, which is quick and convenient. During maintenance, both the outer cover plate 300 and the inner cover plate 200 are opened to complete the maintenance of the circuit breaker. There is no disassembly process of the outer cover plate 300 and the inner cover plate 200, which has the advantages of simplicity and speed.
