[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the "one embodiment" or "embodiment" referred to herein refers to specific features, structures or characteristics that may be included in at least one implementation method of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0027] The utility model proposes a high-precision voltage monitor, such as Figures 1 to 3 As shown, it includes a high-precision voltage monitor body 1 and a protective cover 2. The protective cover 2 is sleeved on the outside of one end of the high-precision voltage monitor body 1, and the protective cover 2 is installed on the outside of the high-precision voltage monitor body 1 through a mounting mechanism. The outside of the high-precision voltage monitor body 1 is fixedly installed with a wiring terminal 3. The protective cover 2 is used to protect the wiring terminal 3. The mounting mechanism is used to realize the rapid installation and removal of the protective cover 2. The mounting mechanism includes a fixed block 8 fixedly connected to the inside of the protective cover 2, and a clamping groove 9 is provided on the outside of the fixed block 8. The outside of the high-precision voltage monitor body 1 located on one side of the wiring terminal 3 is fixedly connected with an elastic sheet 4, and the shape of the elastic sheet 4 is consistent with the shape of the clamping groove 9. A weakening groove is provided on the inner wall of the elastic sheet 4. Guide grooves 6 are provided on both sides of the high-precision voltage monitor body 1, and a limiting groove 7 is provided inside the guide groove 6. Limiting columns 11 and stabilizing blocks 12 are fixedly connected on both sides of the inner cavity of the protective cover 2. The limiting columns 11 are slidably connected to the inside of the limiting groove 7, and the stabilizing blocks 12 are adapted to the shape of the guide groove 6.

[0028] In this embodiment, the protective cover 2 is sleeved on the outside of the high-precision voltage monitor body 1, and is ready for installation or removal operations. The matching design of the elastic sheet 4 and the clamping groove 9 is the key to achieving rapid installation and removal. When the protective cover 2 is close to the main body 1 of the high-precision voltage monitor, the elastic sheet 4 will be elastically deformed by the pressure of the fixing block 8 inside the protective cover 2, and enter the clamping groove 9 to achieve the connection between the two. By applying force in the opposite direction, the elastic sheet 4 is withdrawn from the clamping groove 9, and the disassembly can be completed. The limiting column 11 and the stabilizing block 12 inside the protective cover 2 cooperate with the guide groove 6 and the limiting groove 7 on the main body 1 of the high-precision voltage monitor to ensure the accuracy and stability of the installation position. The limiting column 11 slides inside the limiting groove 7, and the stabilizing block 12 moves along the guide groove 6. These designs enhance the stability and guidance of the installation of the protective cover 2. With the help of the design of the elastic sheet 4 and the clamping groove 9, the protective cover 2 is quickly connected and disconnected with the main body 1 of the high-precision voltage monitor, which greatly improves the efficiency of installation and disassembly. The close combination of the limiting column 11 and the limiting groove 7 and the precise movement of the stabilizing block 12 along the guide groove 6 ensure the stability and positioning accuracy of the installation, and effectively prevent the shaking or dislocation of the equipment during use.

[0029] like Figures 1 to 3 As shown, the fixing block 8 is located on the external fixed connection limit protrusion 10 on one side of the clamping groove 9, and the high-precision voltage monitor main body 1 is provided with a limit groove 5 on the outside on one side of the elastic sheet 4. The limit protrusion 10 is adapted to the shape of the limit groove 5, and an arc guide groove is provided on one end of the limit groove 5 located on the outside of the high-precision voltage monitor main body 1.

[0030] In this embodiment, when installing the protective cover 2, in addition to the cooperation between the elastic sheet 4 and the snap-in groove 9 mentioned above, the limiting protrusion 10 on the fixing block 8 will also match the limiting groove 5 on the high-precision voltage monitor body 1. This design further enhances the stability of the installation and the accuracy of positioning. When the protective cover 2 is installed in place, the limiting protrusion 10 will be embedded in the limiting groove 5, thereby forming an additional fixing point to prevent the protective cover 2 from moving or rotating after installation. At the same time, the arc-shaped guide groove at one end of the limiting groove 5 plays a guiding role, so that the limiting protrusion 10 can slide into the limiting groove 5 more smoothly, which not only simplifies the installation process, but also improves the accuracy of the installation.

[0031] The working principle of the utility model is as follows: the protective cover 2 is sleeved on the outside of the high-precision voltage monitor body 1, and is ready for installation. When the protective cover 2 is close to the high-precision voltage monitor body 1, the elastic sheet 4 is compressed by the fixing block 8, elastically deforms and enters the clamping groove 9 to achieve a preliminary connection. At the same time, the limiting column 11 and the stabilizing block 12 inside the protective cover 2 are respectively matched with the limiting groove 7 and the guide groove 6 on the high-precision voltage monitor body 1 to ensure the accuracy and stability of the installation position. The limiting protrusion 10 on the fixing block 8 is in contact with the high-precision voltage monitor body 1. The limiting groove 5 on the measuring instrument body 1 matches, further enhancing the stability of the installation and the accuracy of positioning. When the protective cover 2 is installed in place, the limiting protrusion 10 is embedded in the limiting groove 5 to form an additional fixing point to prevent the protective cover 2 from moving or rotating. The arc-shaped guide groove at one end of the limiting groove 5 guides the limiting protrusion 10 to slide in more smoothly, thereby improving the accuracy of installation. By applying force in the opposite direction, the elastic sheet 4 is withdrawn from the clamping groove 9. At the same time, the limiting column 11 slides out of the limiting groove 7, and the stabilizing block 12 moves out along the guide groove 6 to complete the disassembly.

It cannot be determined that the specific implementation of the utility model is limited to these descriptions.
