[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-4 As shown, this utility model embodiment provides a dustproof and waterproof housing structure for an electricity meter, including a housing 1 and heat dissipation holes. Multiple heat dissipation holes are provided on both sides of the housing 1. It also includes a dust cover 2, a return mechanism, an interception mechanism, a guide post 3, a moving ring 4, a water-blocking cover 5, and a positioning mechanism. Compared to existing electricity meter housing structures where the heat dissipation holes provide poor dustproof and waterproof performance, allowing dust and water to easily enter the electricity meter through the holes, potentially causing short circuits or affecting normal operation of the internal circuitry, this embodiment, through the cooperation of the dust cover 2 and the interception mechanism, effectively intercepts external dust, achieving dust protection for the electricity meter. This reduces the amount of dust entering the electricity meter through the heat dissipation holes, minimizing the impact of dust on the internal circuitry. The dust cover 2 and the water-blocking cover 5 further enhance the protection. The combination of these mechanisms achieves waterproofing of the inside of the dust cover 2, reducing the probability of water entering the dust cover 2 and thus reducing the probability of water entering the electricity meter through the heat dissipation holes, ensuring the normal operation of the electricity meter. The return mechanism enables the extension and automatic return of the interception mechanism, allowing staff to adjust the extension state of the interception mechanism according to usage needs, facilitating cleaning of the interception mechanism. The cooperation of the guide post 3 and the moving ring 4 enables the adjustment of the blocking state of the water barrier 5, allowing staff to adjust the blocking state of the water barrier 5 according to usage needs, improving the convenience of the device. The positioning mechanism enables the positioning between the guide post 3 and the moving ring 4, thereby achieving the positioning of the water barrier 5 and ensuring the effectiveness of the water barrier 5. like Figure 1 As shown, dust covers 2 are installed on both sides of the outer casing 1, and the dust covers 2 cover the outside of the heat dissipation holes, as shown. Figure 2As shown, two sets of return mechanisms are installed on both sides of the inner wall of the dust cover 2 via L-shaped rods. Each return mechanism includes a first cylinder 101, a connecting rod 102, a pressing disc 103, and a return spring 104. The return mechanism is connected to an interception mechanism, which includes a mounting frame 201, a first interception layer 202, and a second interception layer 203. A second sealing ring 7 is provided on the outer side of the mounting frame 201. The second sealing ring 7 can seal the dust cover 2 and the mounting frame 201, thereby ensuring the airtightness of the mounting frame 201 when it is inside the dust cover 2. Both the first interception layer 202 and the second interception layer 203 are composed of multiple interception nets. Multiple interception nets can effectively intercept dust, enhancing the dust interception effect of the interception mechanism. A second sealing ring 7 is provided on the outside of the mounting frame 201. The second sealing ring 7 can seal between the dust cover 2 and the mounting frame 201, ensuring the airtightness of the interception mechanism inside the dust cover 2. The cooperation between the dust cover 2 and the interception mechanism can prevent dust from entering the heat dissipation holes, reducing the probability of dust entering the interior of the outer shell 1 through the heat dissipation holes. The return mechanism can adjust the extended state of the interception mechanism, making it convenient for staff to clean the interception mechanism and ensuring the dust interception effect of the interception mechanism. like Figure 1 and Figure 3 As shown, multiple guide posts 3 are installed on both sides of the outer shell 1. A movable ring 4 is sleeved on each guide post 3. A water-blocking cover 5 is installed inside the movable ring 4 via a connecting bracket. The water-blocking cover 5 covers the outside of the dust cover 2. The shape of the water-blocking cover 5 matches the shape of the dust cover 2. The water-blocking cover 5 can block and waterproof the opening of the dust cover 2. Square strips are installed on the outside of the guide posts 3. Square grooves are opened on both sides of the inner wall of the movable ring 4. The width of the square grooves matches the width of the square strips. The square strips can limit the movement of the movable ring 4 through the square grooves, thus ensuring the stability of the movable ring 4 during movement. A sealing groove is opened on the outside of the dust cover 2. A first sealing ring 6 is installed on the inner wall of the water-blocking cover 5. The width of the sealing groove matches the width of the first sealing ring 6. The first sealing ring 6 can seal between the dust cover 2 and the water-blocking cover 5 through the sealing groove, ensuring the sealing performance when the water-blocking cover 5 is blocking the dust cover 2. A positioning mechanism is located on the outside of the movable ring 4, as shown in the figure. Figure 4As shown, the positioning mechanism includes a second cylinder 301, an adjusting rod 302, a positioning socket 303, and a positioning spring 304. Positioning slots are provided on the outer sides of both the guide post 3 and the moving ring 4. The moving ring 4 has one positioning slot, while the guide post 3 has multiple positioning slots arranged vertically. The inner diameter of the positioning slot matches the outer diameter of the insertion end of the positioning socket 303. The water baffle 5 can block and waterproof the dust cover 2, reducing the probability of water entering the interior of the outer casing 1 through the heat dissipation holes, and ensuring the normal operation of the internal circuitry of the outer casing 1. The cooperation of the guide post 3, the moving ring 4, and the positioning mechanism can adjust and position the water baffle 5, making it convenient for staff to use the water baffle 5.

[0026] Working principle: When dust enters the dust cover 2 through the water baffle 5, the first interception layer 202 and the second interception layer 203 inside the interception mechanism intercept the dust, thus achieving dust prevention at the heat dissipation holes. When rainwater falls onto the water baffle 5, the rainwater will flow down along the water baffle 5 because the water baffle 5 and the dust cover 2 are sealed by the first sealing ring 6, thus achieving waterproofing at the heat dissipation holes. When cleaning is required on the first interception layer 202 and the second interception layer 203 inside the interception mechanism, the worker pulls the adjusting rod 302. The adjusting rod 302 moves the positioning socket 303. During the movement, the positioning socket 303 compresses the positioning spring 304, canceling the positioning of the positioning socket 303 between the guide post 3 and the moving ring 4. After cancellation, the worker pushes the moving ring 4 along the guide post 3. The moving ring 4 drives the water shield 5 to open through the connecting bracket. After opening, the worker releases the adjusting rod 302, and the positioning socket 303, under the action of the positioning spring 304, inserts into the guide post 3 and the moving ring 4, achieving positioning of the water shield 5 after opening. Then, the worker pulls the mounting frame 201 to move outward from the dust cover 2. The moving mounting frame 201... Simultaneously, the first intercepting layer 202 and the second intercepting layer 203 inside the mounting frame 201 move with the mounting frame 201. The mounting frame 201 drives the extrusion plate 103 to move inside the first cylinder 101 via the connecting rod 102. The extrusion plate 103 compresses the return spring 104. When the mounting frame 201 moves to the outside of the dust cover 2, the mounting frame 201, the first intercepting layer 202 and the second intercepting layer 203 are in a suspended state. The staff cleans the dust remaining on the first intercepting layer 202 and the second intercepting layer 203 inside the mounting frame 201 by tapping the mounting frame 201. After cleaning, the staff releases the mounting frame 201, and the extrusion plate 103, under the action of the return spring 104, drives the intercepting mechanism to return to its original position via the connecting rod 102.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
