[0001] The utility model belongs to the technical field of electric energy meter display screens, and in particular relates to a waterproof and dustproof sealing structure of an electric energy meter display screen. Background Art

[0002] As a crucial piece of equipment in the field of electricity measurement, energy meters are responsible for accurately recording and displaying the amount of electricity consumed by users. By measuring electrical parameters such as current and voltage, they convert energy usage into readable digital or graphical information for reference by users, power suppliers, and regulatory authorities. The widespread use of energy meters not only promotes the rational allocation of power resources but also improves the efficiency of electricity management.

[0003] As the information exchange window between the meter and the user, the importance of the meter display is self-evident. Using intuitive numbers, symbols, or graphics, the display provides real-time information on meter readings, status, and faults, allowing users to keep abreast of their electricity usage. However, with the diversification of application scenarios, particularly in specialized environments like underwater, the protection of meter displays has become increasingly prominent.

[0004] In underwater environments, due to water permeability and pressure, electricity meter displays are susceptible to water vapor intrusion. This intrusion not only causes condensation inside the display, affecting the display quality, but can also corrode and short-circuit the display's electronic components, leading to damage and even failure of the meter. This damage not only increases repair costs but also compromises the accuracy and reliability of electricity metering. Utility Model Content

[0005] In view of this, the utility model provides a waterproof and dustproof sealing structure for an electric energy meter display screen, which can provide a sealed environment for the electric energy meter display screen, thereby preventing the electric energy meter display screen from being damaged by dust and water vapor entering the electric energy meter display screen.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a waterproof and dustproof sealing structure for an electric energy meter display screen, which includes an electric energy meter body, a display screen protection assembly, and a cover assembly. An opening for displaying the electric energy meter reading is provided in the front of the electric energy meter body, and a display screen is provided above the body. A display screen protection assembly is provided above the display screen. The display screen protection assembly is fixedly connected to the electric energy meter body through the cover assembly, and the display screen protection assembly has two layers.

[0008] On the basis of the above technical solution, the waterproof and dustproof sealing structure of the electric energy meter display screen of the present invention can also be improved as follows:

[0009] Among them, the display screen protection assembly includes an inner protective layer and an outer protective layer. The inner protective layer is located above the display screen and cooperates with the electric energy meter body to form a sealed environment. The covering assembly includes a sealing ring and an electric energy meter upper cover. The sealing ring is located above the inner protective layer and is used to seal the inner protective layer and the electric energy meter body. Above the sealing ring is the outer protective layer, which is used to further seal the display screen. Above the outer protective layer is the electric energy meter upper cover, which is used to fix the outer protective layer, the sealing ring, the inner protective layer and the electric energy meter body together.

[0010] Furthermore, the electric energy meter body has a first recess for accommodating the inner protective layer at the contact point with the inner protective layer, a first annular protrusion is provided above the inner protective layer at the contact point with the sealing ring, and the sealing ring has a first groove corresponding to the first protrusion, and the first recess and the first protrusion cooperate with each other.

[0011] Furthermore, a second annular protrusion is provided below the outer protective layer at a position where it contacts the sealing ring, and a second groove is provided on the sealing ring corresponding to the second protrusion, and the second groove is adapted to the second protrusion.

[0012] Furthermore, the cross-section of the upper cover of the electric energy meter is L-shaped, a third groove is provided at the contact point between the upper cover of the electric energy meter and the outer protective layer, and a third protrusion is provided on the outer protective layer corresponding to the third groove.

[0013] The beneficial effect of adopting the above-mentioned improvement scheme is: by setting the first protrusion, the second protrusion, the third protrusion, the first groove, the second groove, and the third groove, they can be positioned relative to each other while extending the water flow and dust entry channel to prevent water vapor and dust from entering the main body of the electricity meter.

[0014] Furthermore, the area of ​​the inner protective layer is larger than that of the outer protective layer.

[0015] The beneficial effects of adopting the above improved solution are: by setting the area of ​​the inner protective layer to be larger than that of the outer protective layer, the contact area between the inner protective layer and the sealing ring is increased, thereby enhancing the sealing effect.

[0016] Furthermore, the sealing ring is made of rubber.

[0017] Furthermore, rubber pads are provided at the contact point between the first protrusion and the first groove, and at the contact point between the third protrusion and the third groove.

[0018] Furthermore, a hygroscopic material for absorbing water vapor is provided on the inner side of the sealing ring.

[0019] Furthermore, the inner protective layer and the outer protective layer are made of transparent plastic or glass.

[0020] Compared with the prior art, the utility model provides a waterproof and dustproof sealing structure for an electric energy meter display screen with the following beneficial effects:

[0021] Significant waterproof and dustproof performance: The double-layer display screen protection assembly (inner and outer protective layers) and the cover assembly (sealing ring and meter cover) work closely together to form a multi-sealed barrier. This design effectively prevents external moisture and dust from entering the meter, thereby extending the meter's service life and reducing malfunctions caused by moisture and dust.

[0022] Enhanced Sealing: The design utilizes a structure where the first, second, and third protrusions interact with corresponding grooves, achieving precise positioning between components while also further enhancing the sealing effect by extending the ingress path for water and dust. Furthermore, rubber pads at the contact points further enhance the tightness of the seal.

[0023] Improved structural stability: The L-shaped cross-section design of the electricity meter cover not only facilitates installation and disassembly, but also enhances the stability and firmness of the structure through the cooperation of the third groove and the third protrusion, reducing deformation or damage caused by external forces.

[0024] Optimized heat dissipation and moisture resistance: The hygroscopic material inside the sealing ring effectively absorbs any water vapor that enters the sealed space, further ensuring a dry environment within the display and meter. Furthermore, the double-layer design also takes heat dissipation into consideration, preventing overheating caused by sealing.

[0025] Easy maintenance and observation: Both the inner and outer protective layers are made of transparent materials (such as transparent plastic or glass), ensuring good waterproof and dustproof effects while maintaining clear observation of the display. This design makes it easy for users to read the meter readings at any time and also facilitates subsequent maintenance and repair work.

[0026] Improved durability and aesthetics: The entire sealing structure is made of high-quality materials (such as rubber sealing rings, transparent plastic or glass protective layers, etc.), which are highly wear-resistant and corrosion-resistant, and can maintain its good appearance and performance for a long time. At the same time, the neat and beautiful design also enhances the overall quality of the energy meter.

[0027] In summary, the waterproof and dustproof sealing structure of the electric energy meter display screen of this utility model shows significant beneficial effects in terms of waterproof and dustproof, sealing performance, structural stability, heat dissipation and moisture-proof, maintenance and observation, durability and aesthetics.
