[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] like Figure 1-4 This is a schematic diagram of the structure of a multifunctional voltage meter according to a preferred embodiment of the present invention. In this embodiment, the multifunctional voltage meter includes a base 2 and a cover plate 1. The cover plate 1 covers the top of the base 2. A wiring cavity 21 is formed on the top surface of the base 2. Multiple elastic clips 22 are distributed and fixedly connected at the opening of the wiring cavity 21 on the top surface of the base 2. Multiple locking blocks 221 are fixedly connected to the outer wall of the elastic clips 22. Meanwhile, an installation cavity 15 is formed on the bottom surface of the cover plate 1. Locking slots 14 are formed on the outer wall of the cover plate 1 at positions opposite to the elastic clips 22. The elastic clips 22 are movably connected along the inner wall surface of the installation cavity 15. The locking block 221 engages with the locking slot 14, thereby realizing the connection function between the base 2 and the cover plate 1. Arc-shaped locking positions 25 are provided at both ends of the outer wall of the base 2 and the cover plate 1, and the side plate 3 is engaged through the arc-shaped locking positions 25. The side plate 3 effectively prevents the locking slot 14 from separating from the locking block 221, which would cause the base 2 and the cover plate 1 to disintegrate. At the same time, it can also increase the aesthetic appearance of the meter and improve the grip of the operator. An installation port 24 is provided at the splicing point of the front end of the base 2 and the cover plate 1, and a lighting lamp 5 is installed in the installation port 24. The addition of the lighting lamp 5 can improve the operator's ability to use it in dark environments such as at night, making it more practical.

[0026] In this embodiment, a circuit board 4 is installed in the mounting cavity 15 and is electrically connected to the lighting lamp 5. A display screen 41 is fixedly installed on the surface of the circuit board 4. The display screen 41 is 6 inches in size. Multiple buttons 42 are soldered and installed on the surface of the circuit board 4 below the display screen 41. The lighting lamp 5 is controlled by pressing one of the multiple buttons 42.

[0027] In this embodiment, a display window 11 is provided on the top surface of the cover plate 1 at a position opposite to the display screen 41, and the inner wall of the display window 11 is in contact with the outer wall of the display screen 41. The display window 11 makes it easier for the operator to view relevant information more clearly during operation. In addition, an opening 12 is provided on the top surface of the cover plate 1 at a position opposite to the button 42, and the button 42 is movably connected in the opening 12, making it easier for the operator to press the button 42.

[0028] In this embodiment, a battery mounting position 26 is provided on the bottom surface of the base 2. A battery is installed in the battery mounting position 26 and is electrically connected to the circuit board 4, so that the battery can provide power to the circuit board 4. A protective plate 27 is snapped into the bottom of the base 2 at the position opposite to the battery mounting position 26. The protective plate 27 protects the battery and avoids the possibility of direct damage to the battery during use.

[0029] In this embodiment, an arc-shaped locking strip 31 is fixedly connected to the surface of the side plate 3 at a position opposite to the arc-shaped locking position 25, and the outer wall of the arc-shaped locking strip 31 is in contact with the inner wall of the arc-shaped locking position 25. Specifically, after the base 2 and the cover plate 1 are engaged by the locking block 221 in the elastic locking strip 22 and the locking slot 14, the arc-shaped locking strip 31 of the side plate 3 is aligned with the arc-shaped locking position 25 and inserted, so that the arc-shaped locking strip 31 is in contact with the arc-shaped locking position 25. Since there is a certain friction between them, the arc-shaped locking strip 31 is not easy to detach from the arc-shaped locking position 25. If disassembly is required, the side plate can be disassembled by using a tool and prying it.

[0030] In this embodiment, a wiring hole 13 is provided on the top surface of the cover plate 1 below the opening 12. A connector 23 is fixedly connected in the wiring cavity 21 at the position opposite to the wiring hole 13, and the top of the connector 23 is in contact with the bottom surface of the cover plate 1. The test pen is connected to the connector 23 by being inserted through the wiring hole 13, thereby having the ability to perform complete measurements.

[0031] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
