Technical Field

[0001] This utility model belongs to the field of electricity meter technology, and in particular relates to the sealing ring structure of outdoor electricity meter box cover. Background Technology

[0002] In power supply systems, outdoor meters must withstand various complex and harsh natural environments over long periods of time, among which waterproof performance is particularly important. The sealing of outdoor meter box covers mainly relies on simple rubber rings or sealing strips. However, while the sealing method is relatively easy to install, the sealing effect is limited. It fails to fully consider the connection stability and sealing performance between the protective cover and the meter body, which may lead to insufficient contact strength between the sealing element and the meter protective cover. Therefore, it is necessary to provide an outdoor meter box cover sealing ring structure, which adopts a pressure sealing structure to continuously compress the sealing element, ensuring the tightness and sealing effect of the contact position. Utility Model Content

[0012] In the following description, embodiments of the sealing ring structure for the outdoor meter box cover of this utility model will be described with reference to the accompanying drawings.

[0013] Figure 1-4This invention illustrates an embodiment of an outdoor meter box cover sealing ring structure, including a pressure assembly 2 disposed on the right side of a protective box 1. A protective cover 3 is disposed on the front side of the protective box 1. Fixed seats 8 are fixedly connected to the top and bottom of the left side of the protective box 1. Rotating components 9 are fixedly connected to the top and bottom of the left side of the protective cover 3. An arc-shaped groove 10 is formed on the top of the rotating component 9. The fixed seats 8 are slidably connected to the inner cavity of the arc-shaped groove 10. Through the cooperative use of the fixed seats 8, rotating components 9, and arc-shaped groove 10, a certain horizontal displacement space is provided for the protective cover 3 while ensuring a rotational connection between the protective box 1 and the protective cover 3, thereby ensuring that the slot plate 4 and the pressure plate 5 can be accurately aligned and engaged. The pressure assembly 2 includes an operating rod 21 rotatably connected to the right side of the protective box 1. A pressing plate 22 is fixedly connected to the front side of the operating rod 21. A pressing groove 23 is formed on the right side of the protective cover 3. The pressing plate 22 is pressed into the inner cavity of the pressing groove 23. The two sealing rings on the front side of the protective box 1... The protective cover 3 is fixedly connected to the groove plate 4 at both ends. The inner side of the protective cover 3 is fixedly connected to the pressure plate 5. The inner cavity of the groove plate 4 is glued with the sealing strip 6. The pressure plate 5 is inserted into the inner cavity of the groove plate 4 and pressed against the surface of the sealing strip 6. The front side of the inner cavity of the groove plate 4 is provided with an inner inclined surface, and the front side of the pressure plate 5 is provided with an outer inclined surface. Through the action of the inclined surfaces of the groove plate 4 and the pressure plate 5, the protective cover 3 is pushed backward to a certain extent, thereby further compressing the sealing gasket 7 and improving the tightness of the connection between the sealing gasket 7 and the protective box 1 and the protective cover 3. The top and bottom of the front side of the protective box 1 are glued with the sealing gasket 7. The front side of the sealing gasket 7 is tightly fitted with the inner side of the protective cover 3. The right side of the protective box 1 is welded with a fixing block 24. The top of the fixing block 24 and the operating rod 21 are both provided with lock holes 25. The front side of the top of the protective box 1 is fixedly connected with a rain visor 11. The rain visor 11 covers the joint between the top of the protective cover 3 and the top of the pressurizing component 2. Multiple heat dissipation holes 12 are punched on the top of both sides of the protective box 1.

[0014] Working principle: When using this utility model, the user rotates the protective cover 3 to the right and engages it on the front side of the protective box 1. Pushing the protective cover 3 to the right until it is tightly fitted against the front side of the pressure component 2, the user presses it with one hand. At this time, the inner cavities of the pressure plate 5 and the groove plate 4 are on the same horizontal plane. Then, the user rotates the operating lever 21 forward. During the rotation, the operating lever 21 drives the extrusion plate 22 to engage in the inner cavity of the extrusion groove 23. Continuing to rotate the operating lever 21, it extrudes the protective cover 3, causing it to slide to the left. Simultaneously, the rotating component 9 slides on the surface of the fixed base 8. As the protective cover 3 slides, the pressure plate 5 enters the inner cavity of the groove plate 4. Under the pressure of the inclined surfaces of the inner slope of the groove plate 4 and the outer slope of the pressure plate 5, the protective cover 3 generates a certain pushing force on the side facing the protective box 1, further compressing the sealing gasket 7. This allows the top and bottom of the contact position between the protective cover 3 and the protective box 1 to be squeezed and sealed. After the operating lever 21 is rotated to the ninety-degree position, the pressure plate 5 presses against the surface of the sealing strip 6, squeezing and sealing both sides of the release position of the protective box 1 and the protective cover 3. At this time, the two lock holes 25 are on the same axis. The user can use a padlock to simultaneously pass through the two lock holes 25 to fix the operating lever 21 and the protective cover 3.

[0015] In summary, the sealing ring structure of this outdoor meter box cover uses the pressure component 2 to horizontally push the protective cover 3, and with the cooperation of the protective cover 3, the groove plate 4 and the pressure plate 5, it compresses the sealing gasket 7 and the sealing strip 6, thereby sealing the area around the contact point between the protective box 1 and the protective cover 3, thus achieving the purpose of compression pressure sealing.
