The second end of the first moving iron core 22 is connected to the first end of the first connecting rod 23, such as by rotating through the second pin 321, and the second end of the first connecting rod 23 is connected to the first shaft 17. The first connecting rod 23 can be a long strip plate structure.

[0078] When the first coil assembly 21 is energized, magnetic force is generated to attract the first moving iron core 22 to move linearly, thereby driving the moving part 15 to slide through the first connecting rod 23, so that the two-stage automatic rotation switch is switched to power supply I (or power supply II) to close.

[0079] Furthermore, a first elongated hole 231 is disposed at the second end of the first connecting rod 23 . The first elongated hole 231 is extended along the length direction of the first connecting rod 23 . The first shaft 17 passes through the first elongated hole 231 .

The second connecting rod 33 can be a long strip plate structure.

[0083] When the second coil assembly 31 is energized, magnetic force is generated to attract the second moving iron core 32 to move linearly, thereby driving the moving part 15 to slide through the second connecting rod 33, so that the two-stage automatic rotation switch is switched to II power supply (or I power supply) to close.

[0084] Furthermore, a second elongated hole 331 is disposed at the second end of the second connecting rod 33 . The second elongated hole 331 is extended along the length direction of the second connecting rod 33 . The second shaft 18 passes through the second elongated hole 331 .

[0086] See again Figure 1 , Figure 2 and Figure 8 In some embodiments, the plate-shaped body 151 is further provided with a connection groove 1511, and the connection groove 1511 may be through the upper and lower surfaces of the plate-shaped body 151, or the connection groove 1511 may be a groove structure.

The length direction of the connection groove 1511 is perpendicular to the length direction of the first connecting plate 152 or the second connecting plate 153.

[0087] See again Figure 1 and Figure 2 The operating device of the two-stage automatic rotary switch also includes a manual operating mechanism 40, which includes a fixing frame 41, a rotating shaft 42 and a linkage rod 43. The fixing frame 41 is installed on the bracket 11 and is arranged close to the side of the second side plate 122 away from the first side plate 121, or the fixing frame 41 is installed on the side of the second side plate 122 away from the first side plate 121.

[0088] The first end of the rotating shaft 42 is connected to the fixing frame 41, and the second end of the rotating shaft 42 is connected to the first end of the linkage rod 43.

When the staff uses an operating member (such as a wrench) to rotate the rotating shaft 42, the rotating shaft 42 drives the linkage rod 43 to rotate, and the linkage rod 43 transmits the torque to the protrusion 44. The protrusion 44 can drive the movable member 15 to move, thereby realizing the manual conversion function of the operating device of the two-stage automatic rotation switch.

[0090] See again Figure 1 , Figure 2 and Figure 8A first hook is disposed at the first end of the tension spring 16 , and a second hook is disposed at the second end of the tension spring 16 . The first hook is connected and fixed to the connecting shaft 143 , and the second hook is connected and fixed to the moving member 15 .

[0091] In some embodiments, a through slot 1512 is further provided on the plate-like body 151 , and a portion of the second hook protrudes from the through slot 1512 , and then a latch is used to connect the portion of the second hook protruding from the through slot 1512 to fix the second hook.

[0092] In some embodiments, the number of the tension springs 16 is at least two. Of course, it can be two, three, four, five or any other number.

[0093] In some embodiments, Fig.11 This is a schematic diagram of the I power supply closing position state; Fig.12 This is a schematic diagram of the position of the moving part passing the dead point when the I power supply switches to the II power supply; Fig.13 This is a schematic diagram of the closing position of the II power supply; Fig.14 This is a schematic diagram of the moving part's dead point position when the power supply II switches to the power supply I. Figures 15 to 17 The following is the working principle diagram of the operating device of the two-stage automatic rotary switch. Specifically, Fig.15 This is the principle diagram of the operating device when the power is in the closed position; Fig.16 It is the principle diagram of the operation of the operating device when the moving part passes the dead point position; Fig.17 This is the schematic diagram of the operating device's action when the power supply is in the closed position.

[0094] The operating principle of the two-stage automatic rotation switch is as follows: Fig.15 (Can be combined Fig.11 ), when the two-stage automatic rotating switch is in the I power-on position, under the action of the tension spring 16, the rocker assembly 14 always maintains a clockwise rotation trend, thereby pushing the square shaft assembly 13 to always be in a counterclockwise rotation trend, so that the two-stage automatic rotating switch is stably maintained in the I power-on position.

[0095] like Fig.16 (Can be combined Fig.12 ), when the push moving member 15 slides to the right, the tension spring 16 is stretched to store energy before passing the dead point position (the dead point position refers to when the tension direction of the tension spring 16 coincides with the radial direction of rotation of the rocker assembly 14), and the tension direction of the tension spring 16 always makes the rocker assembly 14 in a clockwise rotation trend, and the square shaft assembly 13 also always maintains a counterclockwise rotation trend, so that the two-stage automatic rotation switch is always in the I closing position state.

[0096] When the moving member 15 slides past the dead point, the tension direction of the tension spring 16 changes, causing the swing arm assembly 14 to have a counterclockwise rotation tendency. At the same time, the tension spring 16 releases energy, causing the swing arm assembly 14 to rotate rapidly in the counterclockwise direction, thereby driving the square shaft assembly 13 to rotate rapidly clockwise, causing the two-stage automatic rotation switch to switch to the II power on position, and under the tension of the tension spring 16, the two-stage automatic rotation switch is stably maintained in the II power on position (can be combined with Fig.13 and Fig.17 shown).

[0097] When the moving member 15 is pushed to slide to the left, the two-stage automatic rotation switch can be driven to switch to the power on position (as shown in FIG. Fig.14 As shown), the two-way power conversion function of the two-stage automatic rotary switch is realized.

[0098] The operating device of the two-stage automatic rotary switch utilizes the conversion actuator 10 to stretch the tension spring 16 to store energy before passing the dead point position, and the two-stage automatic rotary switch is always kept in the state of closing one power supply. After passing the dead point, the tension spring 16 releases energy, so that the two-stage automatic rotary switch is quickly switched to closing with the other power supply.

[0099] The operating device of the two-stage automatic rotary switch improves the switching speed of the contacts, improves the connection and disconnection capacity of the two-stage automatic rotary switch, makes the performance of the two-stage automatic rotary switch more stable, safe and reliable, and thus can improve the service life of the two-stage automatic rotary switch. The operating device of the two-stage automatic rotary switch has a relatively simple structure, is easy to install, and has a low cost, and can be suitable for production, sales and promotion.
