[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5 This utility model provides an energy meter with an easy-to-replace display screen, including a bracket 1 installed inside the energy meter. A display screen body 3 is placed on top of the bracket 1. A cover plate 2 is provided on top of the bracket 1, pressing down on the display screen body 3. A first rubber pad 8 is adhered to the contact surface between the cover plate 2 and the display screen body 3. Multiple positioning blocks 4 have second rubber pads 9 adhered to their contact surfaces with the display screen body 3, making the contact between the display screen body 3 and the positioning blocks 4 and the cover plate 2 a flexible contact, thus avoiding the possibility of damage due to hard contact. Positioning blocks 4 are adhered to the four corners of the bracket 1, and the display screen body 3 is located within the positioning blocks 4. A limiting component for fixing the display screen body 3 is provided between the positioning blocks 4 and the display screen body 3. A push-out component is provided on the top of the bracket 1 to assist in pushing up the cover plate 2. When installing the display screen body 3, first place the display screen body 3... Between multiple positioning blocks 4, the cover plate 2 is placed on top of the display screen body 3, and the cover plate 2 is in contact with the top of the bracket 1 on all four sides. Then, the limiting component is used to fix the cover plate 2, thereby completing the installation of the display screen body 3. When the display screen needs to be replaced, the fixing of the cover plate 2 by the limiting component is released. Under the action of the ejection component, the cover plate 2 will be automatically lifted by the ejection component, thereby separating it from the bracket 1. The cover plate 2 can be directly removed, and the display screen body 3 can be picked up and replaced. The cover plate 2 presses against the display screen body 3 on all four sides, increasing the contact area between the cover plate 2 and the display screen body 3, thereby reducing the force of single-point contact between the cover plate 2 and the display screen body 3. At the same time, the cover plate 2 protects the display screen body 3 on all four sides, making it less susceptible to bumps and improving the protection effect of the display screen body 3.

[0024] In this utility model, the limiting component includes sliding grooves 10 on both sides of the positioning block 4. Sliding holes 13 are provided on the side contact surfaces of the cover plate frame 2 and the positioning block 4. A first slider 14 that can be inserted into the sliding groove 10 is slidably connected in the sliding hole 13. A second spring 15 is fixed between the first slider 14 and the sliding hole 13 by bolts. The positioning block 4 is provided with a pressing component to push out the first slider 14. During the installation of the cover plate frame 2, the positioning block 4 will press the inclined surface on one side of the first slider 14, so that the first slider 14 slides into the sliding hole 13, thereby compressing the second spring 15 to generate elastic force. When the cover plate frame 2 contacts the bracket 1, the compressed second spring 15 returns to its original position and pushes the first slider 14 to move out of the sliding hole 13, so that one end of the first slider 14 is inserted into the sliding groove 10, thereby completing the fixation of the cover plate frame 2 and improving the stability of the cover plate frame 2 installation. When it is necessary to disassemble the cover plate frame 2, the pressing component can be used to move the first slider 14 out of the sliding groove 10, thereby releasing the fixation between the cover plate frame 2 and the positioning block 4.

[0025] Furthermore, the extrusion assembly includes a second slider 16 that slides within the groove 10, and the second slider 16 is in contact with the first slider 14. Two grooves 10 located on the same positioning block 4 are connected, and an extrusion frame 12 is slidably connected at the connection point of the two grooves 10, with the extrusion frame 12 in contact with the second slider 16. Two rows of mounting grooves are provided at the bottom of each of the multiple second sliders 16, and ball bearings 17 roll within these grooves to reduce friction between the second sliders 16 and the support 1, allowing the second sliders 16 to slide more easily within the groove 10. When the first slider 14 is inserted into the groove 10, the first slider 14 pushes the second slider 16 into the groove 10, thereby extruding the inclined surface on one side of the extrusion frame 12, causing the extrusion frame 12 to... When the first slider 14 stops inside the groove 10, one side of the second slider 16 contacts one side of the extrusion frame 12. When it is necessary to push the first slider 14 out of the groove 10, the extrusion frame 12 is pushed down, so that the inclined surfaces on both sides of the extrusion frame 12 simultaneously extrude the two second sliders 16 located on the same positioning block 4 and move them outward, thereby pushing the first slider 14 outward. When the extrusion frame 12 moves to the bottom, one end of the second slider 16 is flush with one side of the groove 10, so that the first slider 14 is completely inserted into the sliding hole 13, thereby enabling the cover plate frame 2 to be disassembled. Only one action is needed to complete the fixation and release of both sides of the positioning block 4, improving the convenience of disassembling the cover plate frame 2.

[0026] Furthermore, the top of the cover plate frame 2 is provided with a clearance hole 11, and the top of the extrusion frame 12 can be inserted into the clearance hole 11. The top of the multiple extrusion frames 12 is provided with a special disassembly tool 18, and the bottom of the special disassembly tool 18 can be inserted into the clearance hole 11 to push the multiple extrusion frames 12 downward. When the cover plate frame 2 is installed, the top of the extrusion frame 12 does not exceed the top of the clearance hole 11. When the cover plate frame 2 needs to be disassembled, the special disassembly tool 18 is used to contact the extrusion frame 12, so that the four corners of the special disassembly tool 18 are inserted into the clearance hole 11. Pressing the special disassembly tool 18 downward can simultaneously move the extrusion frames 12 at the four corners downward, thereby completing the rapid downward movement of the multiple extrusion frames 12 and further improving the convenience of disassembling the cover plate frame 2.

[0027] The ejector assembly includes grooves 5 on all four sides of the top of the bracket 1. A top frame 6 is slidably connected in the grooves 5. A first spring 7 is fixed between the top frame 6 and the grooves 5 by bolts. During the installation of the cover plate frame 2, the cover plate frame 2 will contact the top frame 6. As the cover plate frame 2 continues to be installed, it will push the top frame 6 into the grooves 5. At the same time, the first spring 7 will be compressed and generate elastic force. During the disassembly of the cover plate frame 2, when the first slider 14 is removed from the slide groove 10, the compressed first spring 7 will reset and push the top frame 6 upward, thereby pushing the cover plate frame 2 upward. This will cause the cover plate frame 2 to disengage from the positioning block 4, eliminating the need to manually remove the cover plate frame 2. This allows for faster disassembly when the cover plate frame 2 is installed on the electricity meter and flush with the top of the electricity meter, improving the convenience of disassembling the display screen.

[0028] The working principle of this utility model is as follows: When installing the display screen body 3, the display screen body 3 is first placed between multiple positioning blocks 4, and then the cover plate frame 2 is placed on top of the display screen body 3. During the installation of the cover plate frame 2, the positioning blocks 4 will press the inclined surface on one side of the first slider 14, causing the first slider 14 to slide into the sliding hole 13, thereby compressing the second spring 15 to generate elastic force. When the cover plate frame 2 contacts the bracket 1, the compressed second spring 15 returns to its original position and pushes the first slider 14 to move out of the sliding hole 13, thereby inserting one end of the first slider 14 into the sliding groove 10, thus completing the fixation of the cover plate frame 2 and completing the installation of the display screen body 3. At the same time, the first slider 14 will push the second slider 16 to move into the sliding groove 10, thereby pressing the inclined surface on one side of the pressing frame 12, causing the pressing frame 12 to move upward. When the first slider 14 stops in the sliding groove 10, one side of the second slider 16 contacts one side of the pressing frame 12. In addition, the cover plate frame 2 will contact the top frame 6. Continuing to install the cover plate frame 2 will cause the cover plate frame to... 2. The top support 6 moves into the groove 5, simultaneously compressing the first spring 7 to generate elastic force. When the display screen needs to be replaced, a special disassembly tool 18 is used to contact the top support 12, so that all four corners of the special disassembly tool 18 are inserted into the clearance holes 11. Pressing the special disassembly tool 18 downwards can simultaneously move the top support 12 at the four corners downwards, thereby completing the rapid downward movement of multiple top supports 12. The downward movement of the top support 12 causes the inclined surfaces on both sides of the top support 12 to simultaneously compress the two second sliders 16 located on the same positioning block 4. The first slider 14 moves outward, and when the pressing frame 12 moves to the bottom, one end of the second slider 16 is flush with one side of the slide groove 10, so that the first slider 14 is completely inserted into the slide hole 13. At this time, the compressed first spring 7 resets and pushes the top frame 6 to move upward, thereby pushing the cover plate frame 2 to move upward, so that the cover plate frame 2 is disengaged from the positioning block 4, and the cover plate frame 2 can be directly removed, so that the display screen body 3 can be taken out and replaced.
