The limit seats are fixedly provided on both sides of the circuit breaker body.

[0006] Preferably, the upper semi-circular part of the rotating groove protrudes from the top of the circuit breaker body and is circular inside, with a square opening at the top.

[0007] To better achieve the limiting effect, the limiting seat is provided in two symmetrical sets, with the bottom of the inner side of the limiting seat tilted inward and the upper part arranged in an arc shape.

[0008] To achieve the purpose of providing support more quickly, the support frame is made of flexible plastic material, and the ribs are made of elastic metal material.

[0009] Furthermore, the front end of the support frame is flat-headed.

[0010] To achieve the limiting effect, the support frame is supported below the limiting seat.

[0011] The beneficial effects of this utility model using the above structure are as follows: The circuit breaker anti-misoperation mechanism proposed in this solution has a support frame rotatably installed on the opening and supported on the limit seat, thereby avoiding accidental contact with the adjacent switch when closing, thus effectively avoiding safety accidents.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention proposes a circuit breaker anti-misoperation mechanism, including a fixed base 1, a screw hole 2, a circuit breaker body 3, and an anti-misoperation structure 4. The screw hole 2 penetrates the fixed base 1, and the circuit breaker body 3 is fixedly mounted on the screw hole 2. The anti-misoperation structure 4 is mounted on the circuit breaker body 3 and includes a rotating groove 5, an internal rotating switch 6, a connecting seat 7, an opening 8, a rotating port 9, a rotating shaft 10, a rotating cylinder 11, a support frame 12, a rib 13, and a limiting seat 14. The rotating groove 5 is fixedly mounted inside the circuit breaker body 3. The upper semi-circular part of the rotating groove 5 protrudes from the top of the circuit breaker body 3 and is circular inside. A square opening is opened at the upper end, and the rotating switch 6 is rotatably mounted inside the rotating groove 5 and controls the opening and closing of the circuit breaker body 3. The circuit breaker body 3 is closed. The connecting seat 7 is fixedly installed on the outside of the internal rotary switch 6. The opening 8 is fixedly installed on the upper end of the connecting seat 7. The rotating port 9 is recessed in the middle of the opening 8. The rotating shaft 10 passes through the rotating port 9 and is fixedly installed on the opening 8. The rotating cylinder 11 is inserted through the rotating shaft 10 and rotates. The support frame 12 is fixedly installed on the outside of the rotating cylinder 11. The support frame 12 is made of flexible plastic material. The front end of the support frame 12 is flat. The rib 13 is installed inside the support frame 12. The rib 13 is made of elastic metal material. The limit seat 14 is fixedly installed on both sides of the circuit breaker body 3. The limit seat 14 is arranged in two symmetrical sets, with the bottom of the inner side of the limit seat 14 tilted inward and the upper part arc-shaped. The support frame 12 is supported below the limit seat 14.

[0020] In practical use, first connect the circuit breaker body 3 to the circuit, and then fix it to the fixing seat 1. When closing or opening the circuit, bend the support frame 12 and pry the front end of the support frame 12 out of the groove of the limit seat 14. Then rotate the rotating cylinder 11 on the support frame 12 to rotate on the rotating shaft 10, and at the same time pry the opening 8 and the connecting seat 7, thereby driving the internal rotary switch 6 to rotate in the rotating groove 5 to control the circuit to close or open, thereby performing closing control. Then bend the support frame 12 so that the front end of the support frame 12 is inserted into the groove of the limit seat 14 for limiting, thereby preventing accidental contact when rotating the adjacent connecting seat 7 and the opening 8, thus achieving safe use of the circuit breaker. The above is the entire process of using the circuit breaker's anti-misoperation mechanism.
