The warning light bar is embedded in the front surface of the circuit breaker body, and the insulating base is arranged at the lower part of the circuit breaker body and is an integrated molding structure. The present invention is provided with a gap filling protection device, which can flexibly block the gap left at the circuit breaker switch without affecting the normal swing of the circuit breaker switch, that is, when the switch is opened upward, its lower edge loses the cover of the handle, exposing a larger gap, and the gap is blocked by an inflated airbag. At this time, the upper edge of the switch does not need to be filled because it is covered by the handle, and the airbag is in a contracted state, which can prevent it from affecting the swing of the switch, and can effectively prevent insects, dust and water vapor from entering the circuit breaker to protect the circuit breaker.

[0004] In the prior art including the above patents, it is undoubted that external circuit breakers need to pay attention to waterproofness. Such IoT external circuit breakers will be designed with displays, control buttons, reset switches, etc. on the surface. Although the corrosion-resistant plastic film set on the surface can prevent the entry of water vapor within a certain period, the waterproofness will be weakened or even lost as the corrosion-resistant plastic film ages due to exposure to sunlight, temperature changes, etc. Summary of the invention

[0031] like Figure 1-4 As shown, a cover plate of an external circuit breaker control panel includes a body 1, and also includes a cover plate 2 with a covering eave 21 fixedly arranged on a first side, and the cover plate 2 is rotatably matched with the body 1 through a rotating shaft 22 symmetrically fixedly arranged on a second side, and is used to cover the operation panel on the body 1;

[0032] The end of the covering eave 21 and one side facing the top of the operation panel is chamfered, and a water retaining edge 5 is fixedly provided on the chamfer, and the water retaining edge 5 is slidably connected to the top of the operation panel.

[0033] Specifically, in the above embodiment, the rotating shaft 22 and the shaft rod in the groove of the side wall of the body 1 are assembled through a damping bearing to form a rotational fit. The cover plate 2 is manually driven to flip for opening and covering.

[0034] Secondly, the cover plate 2 is a transparent acrylic plate, and the water retaining edge 5 is a corrosion-resistant and high-temperature-resistant elastic rubber block, and its cross section is a right-angled triangle structure, and its right-angled side corresponds to the cover plate 2.

[0035] In the above technology, the control panel of the body 1 is covered by the cover plate 2 which is turned over, and then the cover eaves 21 cover the top of the control panel, thereby shielding the junction between the cover plate 2 and the control panel. When the cover eaves 21 cover the top of the control panel, the water retaining edge 5 will come into contact with the top of the control panel, thereby causing its deformation, preventing rainwater from seeping into the junction between the top of the control panel and the end of the cover eaves 21.

[0036] As an embodiment further provided by the present invention, an annular rubber gasket 3 is provided on the inner side of the cover plate 2 , and the annular rubber gasket 3 can be in contact with the operation panel.

[0037] Specifically, the annular rubber gasket 3 in the above embodiment forms a certain gap between the cover plate 2 and the control panel, thereby forming a buffer space, and can increase the sealing after covering.

[0038] As another embodiment further provided by the present invention, Figure 2 As shown, an arc-shaped annular groove 26 is provided on the end surface of one of the rotating shafts 22;

[0039] A slot 25 is formed on the end surface of the rotating shaft 22. The arc-shaped annular groove 26 has a high position and a low position. The slot 25 is connected to the low position.

[0040] Secondly, a blocking portion 4 is provided in the arc-shaped annular groove 26 at the junction of the low position and the high position.

[0041] Furthermore, a non-return slope 23 is provided at the junction of the high position and the slot 25 , and a guide slope 24 is provided on the opposite side of the non-return slope 23 .

[0042] Furthermore, a positioning member 6 having a blocking spring 62 mounted on a first end and a protrusion 61 on the other end surface is fixedly mounted on the shaft rod. The blocking spring 62 in a deformed state enables the protrusion 61 to slide in the arc-shaped annular groove 26 .

[0043] Specifically, in the embodiment, when the cover plate 2 is in Figure 1 When the cover plate 2 is in the open state, the raised portion 61 is located in the slot 25. The operator presses the cover plate 2 toward the control panel, causing the annular rubber gasket 3 to deform to the limit and unable to be pressed. During the process, the raised portion 61 passes over the check slope 23 and reaches the guide slope 24. At this time, the blocking spring 62 pushes down to move the positioning member 6 toward the inside of the slot 25. The raised portion 61 is tangent to the inclined surface of the arc-shaped annular groove 26 and automatically opens under the push of the blocking spring 62.

[0044] When closing, the cover plate 2 only needs to be directly closed on the control panel, and the cover plate 2 can be stopped when resistance is felt. At this time, the protrusion 61 passes over the anti-return slope 23 and enters the slot 25.

[0045] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
