DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0023] like Figure 1-4 As shown, the utility model provides a circuit breaker anti-electric shock protection structure, including a circuit breaker 1, a placement slot and a switch 3 are provided on the front of the circuit breaker 1, a power-off protection device is provided inside the placement slot 2, and an auxiliary installation device is provided on the outer wall of the circuit breaker 1; the power-off protection device includes a movable slot 401, a mounting slot 402 is provided at the bottom of the placement slot 2, a tooth plate 403 is slidably connected inside the movable slot 401, a spring A404 is fixedly connected inside the mounting slot 402, the upper end of the spring A404 is fixedly connected to the tooth plate 403, a tooth block 405 is fixedly connected to the side of the switch 3 close to the tooth plate 403, the tooth block 405 is meshed with the tooth plate 403, a sliding slot 406 is provided on the outer wall of the circuit breaker 1, a toggle rod 407 is fixedly connected to the side of the tooth plate 403, and the toggle rod 407 is slidably connected to the sliding slot 406.

[0024] The power-off protection device further comprises a moving groove 408 , which is provided on the side of the toggle rod 407 , and a blocking rod 409 is slidably connected inside the moving groove 408 .

[0025] The power-off protection device further comprises a slot 410 , which is provided on the outer wall of the circuit breaker 1 , and an expansion airbag 411 is arranged inside the slot 410 .

[0026] In this embodiment, by providing a power-off protection device, the three groups of switches 3 can be opened simultaneously without contacting the circuit breaker 1 itself. Since the contact is reduced, the safety is improved. At the same time, when a fire occurs, the power can be quickly cut off to avoid further losses.

[0027] When in use, when it is necessary to turn on the switch 3, the toggle rod 407 is pushed downward, and then the toggle rod 407 will drive the tooth plate 403 to move to the lower end inside the movable groove 401, and then under the meshing action, one end of the switch 3 will be driven to rotate through the tooth block 405. When the toggle rod 407 is pushed downward to a certain position, the blocking rod 409 is pushed inwardly, so that the blocking rod 409 slides toward the inside of the circuit breaker 1 itself, until it enters the slot 410, thereby limiting the toggle rod 407, that is, ensuring the opening of the switch 3, because the contact with the circuit breaker 1 is reduced, the safety is improved. At the same time, when a fire occurs, the ambient temperature of the circuit breaker 1 will increase, and then the expansion airbag 411 will expand, and then the blocking rod 409 will be squeezed out of the slot 410, and then under the action of the spring A404, the tooth plate 403 will be pushed to slide upward, and also under the meshing action, one end of the switch 3 will be driven to rotate through the tooth block 405, and then it will be closed, achieving the effect of power-off protection. Example

[0028] like Figure 5 As shown, on the basis of Example 1, an auxiliary installation device is added, including a fixed block 601, which is fixedly connected to the outer wall of the circuit breaker 1, and the upper end of the fixed block 601 is fixedly connected to a spring B602, the upper end of the spring B602 is fixedly connected to a clamping plate 603, and the side of the clamping plate 603 is fixedly connected to a connecting block 604.

[0029] Two clamping plates 603 are provided and are symmetrically arranged at the upper and lower ends of the fixing block 601 .

[0030] The toggle end of the switch 3 is fixedly connected with a connecting plate 6 .

[0031] In this embodiment, the auxiliary installation device is provided to facilitate the installation of the circuit breaker 1, thereby increasing the installation speed and the efficiency.

[0032] During use, when the circuit breaker 1 needs to be installed, the connecting block 604 is pressed to make the upper and lower clamping plates 603 approach the fixed block 601. When the clamping plate 603 is inserted into the mounting plate to be installed, the connecting plate 6 is released and then, under the action of the spring B602, the clamping plate 603 is pushed to the upper and lower ends, thereby realizing the quick installation of the circuit breaker 1.
