[0021] In order to make the purpose, technical solutions and advantages of the implementation of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings in the embodiments of the present utility model. In the drawings, the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of the present utility model. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0023] As Figure 1 、 2 shown, the position indicating device of the three-position switching switch electrical operating mechanism provided in the embodiment of the present utility model includes a main spring mechanism 1, a gear assembly 2, and an indicating rod 19. The gear assembly includes a first gear 201. The main spring mechanism includes a connecting body 101 and a spring 102. One end of the connecting body is rotatably connected to the gear assembly. The other end of the connecting body passes through a limiting shaft A. The spring is installed on the connecting body. The indicating rod is installed on a first pin shaft 7 and can rotate relative to the first pin shaft. One end of the indicating rod is connected to the gear assembly 2. It should be noted that the first pin shaft 7 is fixed to the frame of the mechanism.

[0024] The first gear is connected to the main circuit structure of the switching switch electrical appliance. When the switching switch electrical appliance is in the double-off position, the spring on the connecting body is axially compressed and energy-stored by the limiting shaft. When the spring releases energy, it can drive the gear assembly 2 to rotate, thereby driving the main circuit structure of the switching switch electrical appliance to work, so that the switching switch electrical appliance is in the normal state or the standby state. When the gear assembly 2 rotates, it drives the indicating rod to rotate, thereby indicating the working state of the switching switch electrical appliance.

[0025] Specifically, in this embodiment, a second pin shaft 6 is fixedly installed on the gear assembly 2. One end of the indicating rod is provided with an opening chute 5, and the indicating rod is connected to the second pin shaft through the opening chute. When the gear assembly rotates, the indicating rod drives the rotation relative to the first pin shaft through the second pin shaft, and the opening chute of the indicating rod does not come out of the second pin shaft. The other end of the indicating rod is provided with an indicating plate 4, and three working state indicating marks are provided on the indicating plate, namely the normal power supply (Power Supply 1) 10, the standby power supply (Power Supply 2) 8, and the double-off position 9.

[0026] The top of the connecting body forms an annular structure 103, and the connecting body passes through the limiting shaft through the annular structure. A limiting plate 104 is also sleeved on the connecting body between the limiting shaft and the spring. The function of setting the limiting plate 104 is to guide the connecting body and the spring to ensure their positions on the limiting shaft.

[0027] The gear assembly is rotatably installed on the mechanism main shaft 3, and the mechanism main shaft is fixedly installed on the frame of the mechanism. This frame is a part of the operating mechanism of the change-over switch and is stationary. To ensure the synchronous movement of the second pin shaft 6 and the first gear, it can also be considered that the gear assembly 2 further includes at least one connecting plate 202. The connecting plate is fixedly installed on one side of the first gear, and the connecting plate is rotatably connected to the connecting body through a third pin shaft 20.

[0028] As Figure 2 shown, the first gear 201 is connected to the main circuit structure of the change-over switch electrical appliance through the second gear 15. When the main spring mechanism 1 after energy storage releases energy in different directions, the first gear drives the second gear to rotate in different directions, thereby driving the main circuit structure of the change-over switch electrical appliance to realize the switching between the normal state and the standby state. Specifically, the main circuit structure includes the power supply I incoming line end 11, the power supply II incoming line end 12, the outgoing line end 16, the moving contact 13, and the main circuit main shaft 14; the second gear 15 is fixed on the frame. When the gear assembly 2 rotates, it can drive the second gear 15 to rotate, thereby driving the main circuit main shaft 14 to rotate. The main circuit has three working positions: power supply I connection (the moving contact 13 is connected to the power supply I incoming line end 11), power supply II connection (the moving contact 13 is connected to the power supply II incoming line end 12), and double-off position (i.e., Figure 2 the middle position shown).

[0029] It should be noted that the energy storage process and the energy release process after energy storage of the main spring mechanism 1 can refer to the structures in patents CN202210605449.5 and CN202210602270.4, and will not be elaborated here.

[0030] As an example, in this embodiment, as Figure 3 , 4, as shown in Figure 5, there is a panel 17 on the front of the product, with a window 18 opened on it, through which the indication mark of the indicator plate 4 can be observed; as Figure 3 shown, when the gear assembly rotates to the power supply I station, the moving contact 13 is connected to the power supply I incoming line end 11, and the second pin shaft 6 drives the indicator plate 4 to rotate. The power supply I indication, that is, the normal power supply 10, can be observed through the window 18; as Figure 4 shown, when the gear assembly rotates to the double - split station, the moving contact 13 is not connected to the power supply incoming line ends 11 and 12, and the second pin shaft 6 drives the indicator plate 4 to rotate. The double - split position 9 can be observed through the window 18; as Figure 5 shown, when the gear assembly rotates to the power supply II station, the moving contact 13 is connected to the power supply II incoming line end 12, and the second pin shaft 6 drives the indicator plate 4 to rotate. The power supply II indication, that is, the standby power supply 8, can be observed through the window 18.

[0031] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
