[0032] See Figures 1 to 8 , some embodiments of the present application disclose an operating mechanism applied to an automatic transfer switch.

[0033] As Figure 1 and Figure 2 shown, the operating mechanism provided by the present application is mainly applied to an automatic transfer switch to control the switching between two power sources. The operating mechanism includes a support body and a rotating rod 3. The rotating rod 3 is rotatably arranged on the support body; a sliding groove 4 is arranged on the support body. The sliding groove 4 is arc-shaped, and the center of the arc of the sliding groove 4 is concentric with the rotation center of the rotating rod 3; a sliding rod 5 is movably arranged in the sliding groove 4. The sliding rod 5 is connected to the rotating rod 3, and when the sliding rod 5 moves in the sliding groove 4, it drives the rotating rod 3 to rotate. Specifically, as Figure 6 shown, along the extending direction of the sliding groove 4, when the sliding rod 5 moves to the left end of the sliding groove 4, the sliding rod 5 drives the rotating rod 3 to rotate leftward and makes the automatic transfer switch control one of the power sources to be turned on; as Figure 7 shown, when the sliding rod 5 moves to the middle of the sliding groove 4, the sliding rod 5 drives the rotating rod 3 to reset and makes the automatic transfer switch control both power sources to be turned off; as Figure 8As shown, when the slide bar 5 moves to the right end of the slide slot 4, the slide bar 5 drives the rotating rod 3 to rotate rightward and enables the automatic conversion switch to control another power supply to be turned on. The operating mechanism of the present application can realize three-position conversion, and has a simple structure, convenient assembly, low cost, and easy maintenance.

[0034] In some embodiments of the present application, Figure 4 As shown, the left end of the slide 4 is provided with a first groove 41, and the right end of the slide 4 is provided with a second groove 42. The first groove 41 and the second groove 42 extend in a direction away from the arc center of the slide 4. Through the arrangement of the first groove 41 and the second groove 42, after the slide bar 5 moves to the two ends of the slide 4, it will enter the corresponding grooves, thereby better locking the position of the slide bar 5. Further, since the slide 4 is in an arc shape, and in this embodiment, the middle position of the slide 4 is lower than the two end positions, a middle recess 43 is formed in the middle of the slide 4. When the slide bar 5 moves to the middle recess 43 of the slide 4, the middle recess 43 can also assist in locking the position of the slide bar 5.

[0035] In some embodiments of the present application, Figure 2 As shown, a tension spring 6 is also provided on the bracket body, one end of the tension spring 6 is connected to the slide bar 5, and the other end of the tension spring 6 is connected to the bracket body. The slide bar 5 is in a movement trend away from the arc center of the slide groove 4 under the tension of the tension spring 6. When the slide bar 5 is located at the first groove 41, the second groove 42 or the middle recess 43, the slide bar 5 can be maintained at the above position due to the force of the tension spring 6, thereby locking the position of the slide bar 5.

[0036] In some embodiments of the present application, Figure 2 As shown, both ends of the slide rod 5 pass through the corresponding slide grooves 4 and are exposed outside the bracket body. Tension springs 6 are respectively provided at both ends of the slide rod 5. By arranging the tension springs 6 outside the bracket body, space can be freed up to place the toggle member 7. Tension springs 6 are provided at both ends of the slide rod 5 to ensure uniform tension.

[0037] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the bracket body includes a first bracket 1 and a second bracket 2 which are arranged opposite to each other, and a slide groove 4 is respectively arranged on the first bracket 1 and the second bracket 2, and a slide rod 5 passes through the slide groove 4 on the first bracket 1 and the second bracket 2 respectively. By dividing the bracket body into the first bracket 1 and the second bracket 2, the structure of the accessories can be simplified, which is convenient for production and maintenance.

[0038] In some embodiments of the present application, Figure 3As shown, the rotating rod 3 is provided with a first connecting member 31, one end of the first connecting member 31 is fixed on the rotating rod 3, and the other end of the first connecting member 31 is provided with a connecting hole 32, and the slide bar 5 passes through the connecting hole 32. Further, the rotating rod 3 is provided with two or more first connecting members 31 to strengthen the connection between the rotating rod 3 and the slide bar 5; the connecting hole 32 is a bar hole or an elliptical hole, which is convenient for cooperating with the movement of the slide bar 5.

[0039] In some embodiments of the present application, Figure 5 As shown, the operating mechanism of the present application further includes a driving device, which includes a toggle member 7, on which a rotating shaft 71 is provided, and the toggle member 7 is provided on the bracket body and can rotate around the rotating shaft 71. The toggle member 7 is provided with a first toggle block 72 and a second toggle block 73, as shown in FIG. Figure 6 As shown in FIG. 1 , when the toggle member 7 rotates to the left, the first toggle block 72 toggle the slide bar 5 to move to the left, as shown in FIG. Figure 8 As shown, when the toggle member 7 rotates to the right, the second toggle block 73 toggle the slide bar 5 to move to the right. The toggle member 7 has a simple structure and can effectively toggle the slide bar 5 to move.

[0040] In some embodiments of the present application, Figure 2 as well as Figures 6 to 8 As shown, the driving device also includes a power device 9, which can be a motor or an electromagnetic device. In the present application, the power device 9 uses a motor that can rotate forward and reverse. The power device 9 has an output shaft 91, and the output shaft 91 is connected to the toggle member 7 through the connecting rod 8 and drives the toggle member 7 to rotate. Further, a second connecting member 92 is provided on the output shaft 91, and the output shaft 91 is connected to the connecting rod 8 through the second connecting member 92. The second connecting member 92 converts the rotation of the output shaft 91 into the left and right movement of the connecting rod 8; the toggle member 7 is provided with a mounting hole 74, and a pin is fixed in the mounting hole 74. The connecting rod 8 is connected to the pin. When the connecting rod 8 moves, it drives the toggle member 7 to rotate at the same time, thereby realizing the electric control drive, and driving the rotating rod 3 to rotate to switch the power supply.

[0041] In addition, the present application also provides an automatic transfer switch for controlling the switching between two power sources.
