[0037] A waterproof electric meter box includes a lower box body 10 and an upper box body 20. The lower box body 10 includes a lower box outer shell 110, and the upper box body 20 includes an upper box outer shell 210 and a cover edge 240. The cover edge 240 protrudes from the top of the upper box outer shell 210, and diversion edges are provided on both sides of the cover edge 240. The lower box outer shell 110 and the upper box outer shell 210 are detachably connected, and a third sealing ring 60 for preventing rainwater from entering is also provided at the connection between the lower box outer shell 110 and the upper box outer shell 210.

[0038] It should be noted that the lower box outer shell 110 and the upper box outer shell 210 in the electric meter box are usually two independent components. During use, the lower box outer shell 110 and the upper box outer shell 210 in the electric meter box need to be combined for use. After combination, there will be a certain gap at the connection between the lower box outer shell 110 and the upper box outer shell 210. In rainy weather, rainwater often flows into the electric meter box through this gap, which may cause the electric meter in the electric meter box to short-circuit or be damaged.

[0039] Therefore, the cover edge 240 provided at the top of the upper box housing 210 can play a role in preventing rainwater from directly falling on the connection between the lower box housing 110 and the upper box housing 210 when it falls, thereby flowing into the meter box. Among them, diversion edges are provided on both sides of the cover edge 240 to guide the rainwater to change the flowing direction, so that the falling rainwater flows down from both sides of the meter box, avoiding directly falling on the connection between the lower box housing 110 and the upper box housing 210, and can effectively prevent rainwater from entering the meter box.

[0040] Specifically, the third sealing ring 60 is arranged at the connection between the lower box housing 110 and the upper box housing 210, which can further effectively prevent rainwater or other liquids from flowing into the interior of the meter box from the connection between the lower box housing 110 and the upper box housing 210. Through the settings of the first sealing ring 2230, the second sealing ring 2330 and the third sealing ring 60, rainwater can be effectively prevented from entering, and rainwater or other liquids are avoided from invading the meter box and causing the meter to short-circuit or be damaged.

[0041] Combined with the attached drawings of the specification Figures 1-8 As shown, one side of the connection between the lower box housing 110 and the upper box housing 210 is hinged through a hinge member 30, and the other side of the connection between the lower box housing 110 and the upper box housing 210 is fixedly connected through a lead sealing member 40. The hinge member 30 includes a first hinge seat 310, a second hinge seat 320 and a hinge column 330. At least one of the first hinge seat 310, the second hinge seat 320 and the hinge column 330 is provided. The first hinge seat 310 is arranged on the outer wall of the lower box housing 110, the second hinge seat 320 is arranged on the outer wall of the upper box housing 210, and the first hinge seat 310 and the second hinge seat 320 are connected through the hinge column 330. The lead sealing member 40 includes a fixed seat 410, a card slot seat 420 and a lead sealing screw 430. At least one of the fixed seat 410, the card slot seat 420 and the lead sealing screw 430 is provided. The fixed seat 410 is arranged on the outer wall of the lower box housing 110, the card slot seat 420 is arranged on the outer wall of the upper box housing 210, and the lead sealing screw 430 is inserted into the fixed seat 410 and the card slot seat 420 for fixedly connecting the fixed seat 410 and the card slot seat 420.

[0042] Make an explanation. The connection method of the lower box housing 110 and the upper box housing 210 realized through the hinge member 30 enables the upper box housing 210 to open and close relative to the lower box housing 110, which not only facilitates the operation of the user, but also ensures the sealing performance of the device when it is closed. As the bridge connecting the two, the strength and durability of the hinge column 330 have an important impact on the stability and service life of the entire device.

[0043] It should be noted that the lead seal component 40 further enhances the safety and reliability of the device. The cooperation between the fixed seat 410 and the card slot seat 420 ensures the tight connection between the upper box shell 210 and the lower box shell 110 in the closed state. The use of the lead seal screw 430 not only provides a simple and effective fixing method, but also, due to its disposable property, can effectively prevent unauthorized opening, and can further protect the electric meter inside the electric meter box in occasions where it is necessary to ensure the safety of items, prevent tampering or leakage.

[0044] Combined with the accompanying drawings of the specification Figures 1-8 As shown, the upper box body 20 further includes an observation component 220 and a protection component 230. The observation component 220 and the protection component 230 are both arranged on the upper box shell 210. The observation component 220 is arranged at the upper part of the upper box shell 210. The observation component 220 includes a mounting hole 2210 opened at the upper part of the upper box shell 210. Along the outside of the mounting hole 2210, a first mounting seat 2220 is arranged. Inside the first mounting seat 2220, a first sealing ring 2230 is arranged. On the first sealing ring 2230, a transparent observation window plate 2240 is arranged. The observation component 220 further includes a first flip cover 2250, and the first flip cover 2250 is hinged to the upper end of the first mounting seat 2220.

[0045] It should be noted that a transparent observation window plate 2240 is arranged in the observation component 220, and the staff can observe the actual situation of the electric meter in the electric meter box in real time through the transparent observation window plate 2240, and then can read the electric meter number without opening the meter box cover, avoiding repeated opening of the cover and protecting the electric meter. The first flip cover 2250 hinged on the first horizontal plate protruding from the upper end of the first mounting seat 2220 can prevent the observation window plate 2240 from being wetted by rainwater and becoming blurred when the staff observes the electric meter on a rainy day, thus preventing the staff from observing the electric meter.

[0046] Specifically, the first sealing ring 2230 is arranged inside the first mounting seat 2220, which plays a role in sealing and protecting the observation component 220, preventing rainwater or other liquids from flowing into the electric meter box through the observation component 220. Through the arrangement of the first sealing ring 2230, the entry of rainwater can be effectively prevented, and the intrusion of rainwater or other liquids into the electric meter box to cause the electric meter to short-circuit or be damaged can be avoided.

[0047] Combined with the accompanying drawings of the specification Figures 1-8As shown, the protection component 230 is arranged at the lower part of the upper box housing 210. The protection component 230 includes a second mounting seat 2310, a second flip cover 2340 and an air switch 2350. A through hole 2320 is formed inside the second mounting seat 2310. The bottom of the air switch 2350 is connected to the wires arranged inside the lower box housing 110. The top of the air switch 2350 passes through the through hole 2320 and is located inside the second mounting seat 2310. A second sealing ring 2330 is arranged inside the second mounting seat 2310. The second flip cover 2340 is hinged to the upper end of the second mounting seat 2310.

[0048] It is explained that the air switch 2350, also known as an air circuit breaker, its main function is to automatically disconnect when the current in the circuit exceeds the rated current, so as to prevent the circuit from being burned due to excessive current. Through the cooperation of the second mounting seat 2310 and the second flip cover 2340, it can prevent the falling rainwater from flowing into the protection component 230, thereby avoiding the short circuit of the air switch 2350 in the protection component 230 and ensuring the safe and stable operation of the meter box.

[0049] Combined with the accompanying drawings of the specification Figure 3 As shown, at least one waterproof joint 50 is further arranged inside the lower box housing 110, and the waterproof joint 50 penetrates through the bottom wall surface of the lower box housing 110.

[0050] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
