[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A dual power switch operating mechanism, such as Figure 1-4As shown, the operating mechanism includes a bracket 1, a mounting block 11 is fixedly connected to the top of the bracket 1, a fixing plate 12 is fixedly connected to one side of the mounting block 11, a buckle shaft 13 is rotatably mounted on the fixing plate 12, and a buckle 14 is fixedly connected to the buckle shaft 13.

[0024] A buckle plate 15 is fixedly connected to one side of the buckle 14, and a buckle spring 16 is sleeved on the buckle shaft 13 and located at one end of the buckle 14. The buckle spring 16 is a torsion spring, one end of which is buckled and connected to the fixed plate 12, and the other end is buckled and connected to one end of the buckle 14.

[0025] A symmetrically distributed support block 17 is fixed inside the bracket 1, a lever 2 is rotatably mounted on the bracket 1, side plates 24 are fixed on both sides of the lever 2, the bottom ends of the side plates 24 are rotatably connected to the support block 17, and a limit shaft 21 is fixed on the side plate 24, a main tension spring 23 is fixed on the lever 2, and the limit shaft 21 is located on one side of the main tension spring 23.

[0026] A trip buckle shaft 18 is rotatably mounted on the bracket 1, and a trip buckle 3 is rotatably connected to the trip buckle shaft 18. The trip buckle 3 is located between the two side plates 24, and upper connecting rods 41 are rotatably provided on both sides of the trip buckle 3. A connecting plate 4 is fixedly provided on one side of an upper connecting rod 41, and the connecting plate 4 is rotatably connected to the trip buckle shaft 18. One end of the trip buckle 3 is fixedly connected to a U-shaped plate 31, and the other end is fixedly connected to a buckle rod 32.

[0027] The U-shaped plate 31 is rotatably connected to the tripping shaft 18. When the lever 2 is in the open state, the U-shaped plate 31 abuts against the limit shaft 21 to stabilize the lever 2. At this time, the limit shaft 21 abuts against the top of the mounting block 11 to prevent the main tension spring 23 from pulling the lever 2 to deviate excessively.

[0028] A reinforcement rod 19 is fixedly installed in the bracket 1, and a lower connecting rod 6 is rotatably provided in the bracket 1. One end of the lower connecting rod 6 is rotatably connected to a connecting rod shaft 5. One end of the main tension spring 23 away from the lever 2 is hooked to the end of the connecting rod shaft 5 to connect the lever 2 and the connecting rod shaft 5. The connecting rod shaft 5 is rotatably installed on one end of two upper connecting rods 41, and the other end of the upper connecting rod 41 is provided with a matching groove 42.

[0029] A matching shaft 34 is also fixedly provided on the trip buckle 3, and the matching shaft 34 matches with the matching groove 42. A re-buckle groove 33 is opened on the buckle rod 32. When the switch is closed, the re-buckle groove 33 matches with the buckle plate 15 on the re-buckle 14. The trip buckle 3 is fixed by pulling the re-buckle 14 through the re-buckle spring 16 to achieve the purpose of locking the lever 2, and the two ends of the re-buckle 14 are fixedly connected with the limit plate 10, and the limit plate 10 abuts against the bottom of the fixed plate 12 to limit the rotation of the re-buckle 14.

[0030] Here’s how it works:

[0031] During the dual power switch control operation process, when the lever 2 is acted upon by an external operating force, it rotates around the support block 17 on the bracket 1, and the lever 2 is linked to the trip buckle 3 to move. When the buckle rod 22 at one end of the trip buckle 3 moves toward the re-buck 14 along with the lever 2, it will support the re-buck 14, and the re-buck 14 will rotate under the force of the buckle rod 22, and then the position of the re-buck 14 will be restricted. At this time, the external operating force is removed, and the re-buck 14 rebounds under the force of the re-buck spring 16, so that the buckle plate 15 cooperates with the buckle groove 33 to lock the trip buckle 3, and it is in the open state at this time;

[0032] If it is to be changed to the closing state, it is necessary to control the lever 2 to move in the closing direction. After moving to a certain angle, the lever 2 will be restricted. At this time, the external operating force is removed, and the lever 2 is linked to the main tension spring 23 to drive the connecting rod shaft 5 to move in the closing direction around the matching shaft 34, overcoming the pressure of the buckle 14 and moving to the connecting rod shaft 5 after passing the dead point and being restricted. At this time, the mechanism will have a closing holding force under the tension of the main tension spring 23.

[0033] The opening and closing structure is stable and the operation is simple and convenient. The traction rod structure in the existing dual power switch switching technology is eliminated, and the amount of bracket 1 can be reduced, thereby reducing the cost of the dual power switch and reducing the assembly operation of the dual power switch.
