A second adjusting assembly 73 is arranged on the shell 21, the second adjusting assembly 73 comprises a third spring 731, one end of the third spring 731 is connected with the fifth adjusting block 72 and the other end is connected with the shell 21; a second rack 732 is fixedly connected on the fifth adjusting block 72 located in the fourth cavity; a first rotating shaft 733 is rotationally connected in the fourth cavity, one end of the first rotating shaft 733 is keyed connected with a second gear 734 engaged with the second rack 732, and the other end of the first rotating shaft 733 away from the second gear 734 is keyed connected with a first bevel gear 735; a second rotating shaft 736 perpendicular to the first rotating shaft 733 is rotationally connected in the fourth cavity, one end of the second rotating shaft 736 is keyed connected with a second bevel gear 737 engaged with the first bevel gear 735, and the other end of the second rotating shaft 736 away from the second bevel gear 737 is keyed connected with a third gear 738, and a third rack 739 engaged with the third gear 738 is keyed connected on the third positioning block 71.

[0058] When the first fixed block 41 is located at the second point, i.e. the second positioning block 61 is clamped with the first first positioning groove, the third positioning block 71 is aligned with the second positioning groove on the adjusting plate 341. When the shell 21 is not installed on the guide rail 1, the third positioning block 71 is clamped with the second positioning groove on the adjusting plate 341, and the second positioning block 61 is clamped with the first first positioning groove on the shell 21; the first positioning block 43 is not clamped with the positioning hole 3311 on the first adjusting block 331. When the shell 21 is installed on the guide rail 1, the second connecting rail 13 is first pressed to move the third adjusting block 333, and then the first connecting rail 12 is placed into the assembling groove, the first connecting rail 12 drives the fifth adjusting block 72 to move, the fifth adjusting block 72 drives the second rack 732 to move, the second rack 732 drives the second gear 734 to rotate, the second gear 734 drives the first rotating shaft 733 to rotate, the first rotating shaft 733 drives the first bevel gear 735 to rotate, the first bevel gear 735 drives the second bevel gear 737 to rotate, the second bevel gear 737 drives the second rotating shaft 736 to rotate, the second rotating shaft 736 drives the third gear 738 to rotate, the third gear 738 drives the third rack 739 to move, the third rack 739 drives the third positioning block 71 to move, so that the third positioning block 71 is separated from the second positioning groove on the adjusting plate 341. Thus, when the fourth adjusting block 64 is pressed by the subsequent operator, the adjusting plate 341 drives the second assembling block 32 to move, so that the second assembling block 32 abuts against the second connecting rail 13.

[0059] The implementation principle of the guide rail type electric meter is as follows: when the shell 21 of the electric meter structure 2 is not connected with the guide rail 1, the first fixing block 41 is located at the second point, the second positioning block 61 is clamped with the first first positioning slot on the shell 21, the third positioning block 71 is clamped with the second positioning slot on the adjusting plate 341, and the first positioning block 43 is not clamped with the positioning hole 3311 on the first adjusting block 331.

[0060] When the shell 21 is installed on the guide rail 1, the fixed rail 11 is first located in the sliding groove 211 of the shell 21, and then the shell 21 is moved, so that the second connecting rail 13 presses the third adjusting block 333, the first connecting rail 12 is aligned with the assembly groove formed by the first assembly block 31 and the shell 21, and then the shell 21 is moved again, so that the first connecting rail 12 enters the assembly groove and drives the fifth adjusting block 72 to move, and when the first connecting rail 12 is completely located in the assembly groove, the fifth adjusting block 72 drives the third positioning block 71 to move through the second adjusting assembly 73, so that the third positioning block 71 is no longer clamped with the second positioning slot on the adjusting plate 341. At this time, the second adjusting block 332 abuts against the second connecting rail 13.

[0061] Then the operator presses the fourth adjusting block 64, so that the second positioning block 61 is separated from the first first positioning slot on the shell 21, and the adjusting plate 341 drives the second assembly block 32 to move towards the first assembly block 31, the second assembly block 32 and the second adjusting block 332 abut against the two sides of the second connecting rail 13 respectively, and at this time the first positioning block 43 is clamped with the positioning hole 3311 on the first adjusting block 331. Under the action of the reset spring 342 and the first positioning block 43, the shell 21 is stably fixed on the guide rail 1.

[0062] When the shell 21 needs to be moved, the operator moves the first fixing block 41 to the third point, so that the first positioning block 43 is still clamped with the positioning hole 3311 on the first adjusting block 331, the second assembly block 32 no longer abuts against the second connecting rail 13, and the second positioning block 61 is clamped with the second first positioning slot on the shell 21, so that the first connecting rail 12 is still located in the assembly groove, the first adjusting block 331 is fixed relative to the shell 21, the second adjusting block 332 remains in the state of abutting against the second connecting rail 13, and when the shell 21 moves on the guide rail 1, the inclination of the shell 21 relative to the guide rail 1 is reduced, so that the shell 21 moves more stably. After the position of the shell 21 is determined, the second assembly block 32 and the second adjusting block 332 are re-abutted against the two sides of the second connecting rail 13.

[0063] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
