[0026] Reference Figure 1-7 , is an embodiment of the present utility model, which provides a new type of guide rail type three-phase multifunctional meter, mainly comprising:

[0027] Measuring instrument body 100, such as Figure 2A guide rail groove 101 is provided on the rear side of the meter body 100, and a slide groove 102 connected to the guide rail groove 101 is provided on the bottom of the meter body 100;

[0028] Guide rail 200, such as Figure 3 The guide rail 200 is U-shaped, and the guide rail groove 101 is movably sleeved on the opening side of the guide rail 200. The bottom of the guide rail 200 is provided with a slot 201 communicating with each other from top to bottom;

[0029] Clamping assembly 300, such as Figure 1 The clamping assembly 300 is connected to the meter body 100 and the guide rail 200 to fix the guide rail 200 and the meter body 100 together;

[0030] The clamping assembly 300 includes a clamping mechanism 301 movably arranged inside the guide rail groove 101 and a limiting mechanism 302 fixedly connected to the clamping mechanism 301. The clamping mechanism 301 is slidably connected to the measuring instrument body 100 and presses against the top of the guide rail 200. The limiting mechanism 302 is movably pressed against the inner bottom wall of the guide rail 200 through the slot 201.

[0031] Specifically, such as Figure 5 The clamping mechanism 301 includes a clamping plate 301-1 movably arranged inside the guide rail groove 101, the top of the clamping plate 301-1 movably abuts the bottom of the guide rail 200, and the inner top wall of the guide rail groove 101 abuts the top of the guide rail 200, and the bottom of the clamping plate 301-1 is fixedly connected to a sliding rod 301-2, and the bottom end of the sliding rod 301-2 slides downward to pass through the guide rail groove 101 and is fixedly connected to a lifting plate 301-3, and the sliding rod 301-2 slides through the slide groove 102, and the lifting plate 301-3 drives the clamping plate 301-1 to move up and down, so that the distance between the clamping plate 301-1 and the inner top wall of the guide rail groove 101 can be adjusted, and thus it is suitable for installing the measuring instrument body 100 on guide rails 200 of different widths, and has good flexibility in use. The limiting mechanism 302 is fixedly connected to the top of the clamping plate 301-1.

[0032] Specifically, both left and right ends of the clamping plate 301-1 protrude from the meter body 100, and the limiting mechanism 302 is fixedly connected to the top of both ends of the clamping plate 301-1. The purpose of this setting is to facilitate the operation of the limiting mechanism 302 without having to put your hand into the guide rail 200 during operation.

[0033] Specifically, such as Figure 6-7The limiting mechanism 302 includes a plug-in plate 302-1 fixedly connected to the top of the clamping plate 301-1, the plug-in plate 302-1 slides through the slot 201, a moving slot 302-2 is opened on the top of the plug-in plate 302-1, a telescopic slot 302-3 connected to the moving slot 302-2 is opened on the front side of the plug-in plate 302-1, a moving rod 302-4 is slidably connected in the moving slot 302-2, and a limiting rod 302-5 is slidably passed through the telescopic slot 302-3, and the inner end of the limiting rod 302-5 is fixedly connected to the moving rod 302-4. A spring 302-6 is fixedly connected between the side away from the limit rod 302-5 and the inner wall of the movable groove 302-2. The bottom of the limit rod 302-5 is movably abutted against the inner bottom wall of the guide rail 200, and the top of the movable rod 302-4 protrudes from the top of the plug plate 302-1. The purpose of this setting is to facilitate the application of pushing force to the movable rod 302-4, and then facilitate the movement of the limit rod 302-5 to the inside of the telescopic groove 302-3 through the movable rod 302-4, thereby facilitating the disassembly and assembly of the limit mechanism 302, that is, facilitating the disassembly and assembly of the measuring instrument body 100.

[0034] In summary, when installing the meter body 100, first, the guide rail groove 101 on the rear side of the meter body 100 is sleeved on the outer side of the opening side of the guide rail 200, and the guide rail groove 101 is in contact with the top of the guide rail 200. Then, the sliding rod 301-2 and the clamping plate 301-1 are driven to move upward by the lifting plate 301-3, and the clamping plate 301-1 is pressed against the bottom of the guide rail 200. Since the clamping plate 301-1 is movable, it is suitable for fixing the meter body 100 on guide rails 200 of different widths. It has little limitation in use and good flexibility in use. In the process of pushing the clamping plate 301-1 upward, by pushing the moving rod 30 2-4 drives the limit rod 302-4 to move inside the telescopic slot 302-3. When the clamping plate 301-1 is pressed against the bottom of the guide rail 200, the limit rod 302-4 passes through the slot 201. At this time, the pushing force of the moving rod 302-4 is released. Under the action of the rebound force of the spring 302-6, the moving rod 302-4 is reset. The moving rod 302-4 drives the limit rod 302-5 to reset and press the limit rod 302-5 against the inner bottom wall of the guide rail 200, so that the clamping plate 301-1 can be fixed, and then the measuring instrument body 100 can be fixed. The overall operation is simple and convenient for disassembly and assembly, which makes it convenient for the later maintenance of the measuring instrument body 100.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
