Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1:

[0021] Please refer to Figures 1-6 , the present invention provides a technical solution: a three-phase watt-hour meter installed in a rail type, including a top plate 100. The lower end surface of the top plate 100 is fixedly connected with a rail 102. A groove 105 is provided in the rail 102, and a plurality of positioning grooves 106 that are equidistant left and right and symmetric front and back are provided in the rail 102. After two connecting blocks 107 are inserted into the groove 105, the two connecting blocks 107 are snapped into two positioning grooves 106 at different distances for quick positioning. And the lower end surface of each connecting block 107 is fixedly connected with a connecting frame 103. The two connecting frames 103 are fixedly connected with the three-phase watt-hour meter 104. Thus, by controlling the two connecting blocks 107 in the positioning grooves 106 with different spacings, the three-phase watt-hour meters 104 of different specifications and sizes can be adapted;

[0022] The rail 102 is provided with a first through hole 111 located in each positioning groove 106, and the rail 102 is provided with a first threaded groove 110 that is vertically aligned with each first through hole 111. Each connecting block 107 is provided with two second through holes 112 that are symmetric front and back. The second through holes 112 can be vertically coaxially aligned with the first threaded groove 110 and the first through hole 111. After a bolt 108 passes through the first through hole 111 and the second through hole 112, it is screwed into the first threaded groove 110. Thus, after driving the connecting block 107 to move upward, the upper end surface of the connecting block 107 is abutted against the upper end wall of the groove 105, and the connecting block 107 is quickly and fixedly installed.

[0023] Each connecting frame 103 is provided with two third through holes 113 that are symmetric front and back;

[0024] On the lower side of every two connecting frames 103, there is a three-phase watt-hour meter 104. The three-phase watt-hour meter 104 is provided with a plurality of second threaded grooves 114 that are vertically coaxially aligned with the third through holes 113;

[0025] The second thread groove 114 is threadedly connected with a screw 109. The screw 109 passes through the third through hole 113, so that the connecting frame 103 and the three-phase watt-hour meter 104 can be fixedly connected. By placing the connecting block 107 in the positioning grooves 106 with different spacings, the three-phase watt-hour meters 104 with different specifications can be quickly and fixedly installed;

[0026] Mounting groove holes 101 are provided at the four corners of the top plate 100. The top plate 100 is mounted at the position where a three-phase watt-hour meter needs to be installed by passing screws through the mounting groove holes 101.

[0027] Working principle:

[0028] First, place the top plate 100 at the position where a three-phase watt-hour meter needs to be installed, and fix it after passing screws through the mounting groove holes 101;

[0029] Then, on the three-phase watt-hour meters 104 with different specifications, place two connecting frames 103 symmetrically left and right on the upper end surface of the three-phase watt-hour meter 104. After passing the screws 109 through each third through hole 113, screw them into the second thread groove 114 to connect the three-phase watt-hour meter 104 and the connecting frame 103. Then, insert the connecting block 107 into the groove 105 from the right side and snap it into two positioning grooves 106 at appropriate positions. Then, pass the bolts 108 through each second through hole 112 and the corresponding first through hole 111, and screw them upward into the first thread groove 110. At the same time, drive the connecting block 107 to move upward, and press the upper end surface of the connecting block 107 against the upper end surface of the groove 105, so as to fixedly install the connecting block 107 and prevent the three-phase watt-hour meter 104 from shaking. Thus, after installing two connecting frames 103 on the three-phase watt-hour meters 104 with different specifications, the connecting block 107 and the guide rail 102 are fixedly connected by bolts 108, and the three-phase watt-hour meters 104 with different specifications can be conveniently loaded and unloaded.
