[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 8 A modular power meter includes a housing 1. The outer and inner surfaces of the two side panels of the housing 1 are provided with several grooves 2. The back panel of the housing 1 has several through holes 3. A circuit board 4 is slidably connected within the grooves 2. Connectors on the circuit board 4 are located within the through holes 3. A mounting base 5 is fixedly connected to the front end of the housing 1. A screen carrier 6 is placed inside the mounting base 5. A display screen 7 and touch buttons 8 are mounted on the screen carrier 6. A front cover 9 is detachably connected to the mounting base 5. Several round holes 10 are provided on the housing 1. An upper cover 11 is detachably connected to the round holes 10. A fixing mechanism 12 for fixing the upper cover 11 is fixedly connected to the back of the housing 1.

[0026] like Figures 1 to 8As shown, in the combined power meter of this utility model, during installation, first align the circuit board 4 with the groove 502 on the fixing plate 501, and push the circuit board 4 inward so that it slides into the groove 2 on both sides of the outer casing 1. Then, snap the screen carrier plate 6 onto the annular plate 503, with the back of the screen carrier plate 6 abutting against the circuit board 4 to fix the circuit board 4. Then, install the front cover 9 on the fixing base 5, and slide the inner wall of the annular plate 901 along the outer wall of the annular plate 503 until the surface of the annular plate 901 is in contact with the surface of the fixing plate 501. At this point, the connecting plate 902 is in contact with the surface of the screen carrier plate 6, the display screen 7 is located inside the second through hole 903 and is in contact with the inner wall of the second through hole 903, and the touch button 8 is located inside the third through hole 904 and is in contact with the inner wall of the third through hole 904, thus initially fixing the screen carrier plate 6. Then, the pressing plates 1206 on the two fixing mechanisms 12 are pressed inward, causing the slide bar 1205 to move inward along the second slide groove 1202 to a certain extent. The spring 1204 is compressed and stores energy until the front end of the slide bar 1205 is inside the second slide groove 1202. Then, the upper cover 11 is connected to the outer shell 1. Next, the insert rod 1104 on the upper cover 11 is inserted into the round hole 10 on the outer shell 1, and the cover plate 1101 is pressed down so that the lower surface of the cover plate 1101 is in contact with the upper surface of the outer shell 1. At this time, the U-shaped groove 1103 on the lower surface of the cover plate 1101 coincides with the U-shaped insert plate 905 on the front cover 9, and the sliding groove 1106 and the sliding groove 2 1202 are connected to each other and are on the same horizontal plane. Through the interaction between the U-shaped groove 1103 and the U-shaped insert plate 905, the upper cover 11 can fix the front cover 9, thereby To prevent the front cover 9 from sliding outward, the pressing plate 1206 is released, and the spring 1204 releases energy, thereby pushing the slide rod 1205 to slide outward and into the slide groove 1106, so that the upper cover 11 can no longer move upward, thus fixing the upper cover 11. This allows the various components of the power instrument to be assembled together, making the operation simple, quick and convenient. The power instrument can be disassembled by following the reverse operation. The outer and inner surfaces of the side plate are provided with several grooves 2, which can not only fix the circuit board 4, but also improve the heat dissipation effect.

[0027] like Figure 5 As shown, the fixing base 5 includes a fixing plate 501 fixedly connected to the front end of the outer shell 1. The fixing plate 501 has a groove 502 that matches the groove 2. An annular plate 503 is fixedly connected to the surface of the fixing plate 501. The screen carrier plate 6 is inserted into the annular plate 503, and the thickness of the annular plate 503 is the same as the thickness of the screen carrier plate 6.

[0028] Specifically, the groove 502 on the fixing plate 501 is for the circuit board 4 to slide into the groove 2, and the circuit board 4 is installed and supported by the groove 2. The fixing plate 501 and the annular plate 503 are used to initially fix the screen carrier 6, so that the screen carrier 6 is stuck in the annular plate for initial fixation.

[0029] like Figure 6 As shown, the front cover 9 includes an annular plate 901 that is slidably connected to the outer surface of annular plate 503. A connecting plate 902 is fixedly connected to the front end of annular plate 901. A through hole 903 and several through holes 904 are provided on the connecting plate 902. The through hole 903 matches the display screen 7, and the through holes 904 match the touch button 8. An insert plate 905 with a concave cross-section is fixedly connected to the end of annular plate 901.

[0030] Specifically, the front cover 9 is installed on the fixing base 5, and the inner wall of the second annular plate 901 slides along the outer wall of the first annular plate 503 until the surface of the second annular plate 901 is in contact with the surface of the fixing plate 501. At this time, the connecting plate 902 is in contact with the surface of the screen carrier plate 6, the display screen 7 is located in the second through hole 903 and is in contact with the inner wall of the second through hole 903, and the touch button 8 is located in the third through hole 904 and is in contact with the inner wall of the third through hole 904, thereby initially fixing the screen carrier plate 6.

[0031] like Figure 7 As shown, the upper cover 11 includes a cover plate 1101. A cooling fan 1102 is installed in the middle of the cover plate 1101. A groove 1103 with a concave cross-section is opened on the lower surface of the cover plate 1101. A plug rod 1104 matching the round hole 10 is fixedly connected to the lower end of the cover plate 1101. Two fixing blocks 1105 are fixedly connected to the end of the cover plate 1101. A sliding groove 1106 is opened on the inner surface of both fixing blocks 1105.

[0032] Specifically, the insert rod 1104 on the upper cover 11 is inserted into the round hole 10 on the outer shell 1, and the cover plate 1101 is pressed down so that the lower surface of the cover plate 1101 is in contact with the upper surface of the outer shell 1. At this time, the U-shaped groove 1103 on the lower surface of the cover plate 1101 coincides with the U-shaped insert plate 905 on the front cover 9, thereby fixing the front cover 9 and making the sliding groove 1106 and the sliding groove 21202 communicate with each other and be in the same horizontal direction.

[0033] like Figure 1 or Figure 2 As shown, a filter 13 is fixedly connected to the upper end of the cooling fan 1102.

[0034] Specifically, filter 13 can effectively prevent dust and insects in the air from entering the electrical instrument.

[0035] like Figure 2 As shown, there are two fixing mechanisms 12, which are arranged symmetrically about the outer shell 1.

[0036] Specifically, the two fixing mechanisms 12 make the fixing effect better, and even if one fixing mechanism 12 is damaged, the other can still play a fixing role.

[0037] like Figure 8 As shown, the fixing mechanism 12 includes a fixing block 1201 fixedly connected to the back plate of the outer shell 1. A sliding groove 1202 is provided in the fixing block 1201. A groove 1203 communicating with the sliding groove 1202 is provided on the surface of the fixing block 1201. A spring 1204 is fixedly connected to the inner wall of the sliding groove 1202. A sliding rod 1205 is fixedly connected to the output end of the spring 1204. A pressing plate 1206 is fixedly connected to the end of the sliding rod 1205.

[0038] Specifically, pressing the pressing plates 1206 on the two fixing mechanisms 12 inward causes the slide rod 1205 to move inward along the second slide groove 1202. The spring 1204 is compressed and stores energy until the front end of the slide rod 1205 is inside the second slide groove 1202. After the upper cover 11 is connected to the outer shell 1, the pressing plates 1206 are released, and the spring 1204 releases energy, thereby pushing the slide rod 1205 to slide outward and into the first slide groove 1106, so that the upper cover 11 can no longer move upward, thus fixing the upper cover 11. In this way, the various components of the power meter are assembled together. The operation is simple, quick and convenient. The power meter can be disassembled by following the reverse operation.

[0039] like Figure 8 As shown, the front end of the slide bar 1205 is provided with a rounded corner.

[0040] Specifically, the front end of the slide rod 1205 is rounded, so that the slide groove 1106 and the slide groove 2 1202 are not on the same horizontal direction. When there is a slight deviation, it is easy for the slide rod 1205 to slide into the slide groove 1106, ensuring the tightness of the assembly of the various parts of the power instrument.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
