[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 8 This utility model provides a technical solution: an anti-accidental-touch intelligent circuit breaker, including a bottom shell 1, a middle frame 2 disposed on one side of the bottom shell 1, and a top cover 3 disposed on one side of the middle frame 2. A handle 5 is rotatably mounted on the bottom shell 1, and a release sleeve 6 is slidably mounted on the outer side of the handle 5. When it is necessary to release the lock on the handle 5, the release sleeve 6 is pulled outward. The release sleeve 6 cooperates with the baffle 13 to compress the spring 14. The release sleeve 6 drives the pull rod 12 to move away from the handle 5. The pull rod 12 pulls the locking rod 10 through the connecting rod 11, causing the locking rod 10 to move away from the third locking hole 19. When the limiting ring 16 is pressed against the handle 5, preventing the release sleeve 6 from moving, the locking rod 10 has completely disengaged from the third locking hole 19, and the handle 5 is no longer locked. Then the handle 5 can be rotated for operation. The inner side of the release sleeve 6 is provided with a pull rod 12 that is slidably connected to the handle 5. The handle 5 is symmetrically slidably mounted with locking rods 10 for fixing the handle 5. A connecting rod 11 is provided between each of the two locking rods 10 and the pull rod 12. One end of the connecting rod 11 is hinged to the pull rod 12, and the other end of the connecting rod 11 is hinged to the locking rod 10. The upper cover 3 has a second locking hole 18, a first locking hole 4, and a third locking hole 19 sequentially provided to cooperate with the locking rods 10. The locking rods 10, in cooperation with the second locking hole 18, the first locking hole 4, and the third locking hole 19, can lock the handle 5, preventing accidental rotation of the handle 5 and improving safety. When the locking rod 10 is in the third position... When the handle 5 is in the lock hole 19, it is in the open position. When the lock rod 10 is in the first lock hole 4, the handle 5 is in the adjustment position. When the lock rod 10 is in the second lock hole 18, the handle 5 is in the closed position. One end of the handle 5 is symmetrically provided with a slide rod 15, which can limit the release sleeve 6, making the release sleeve 6 more stable during movement. A spring 14 is sleeved on the outside of the slide rod 15, which is used to apply a pushing force to the release sleeve 6, so that the release sleeve 6 can automatically reset.

[0022] The release sleeve 6 has a through hole 17, which is used to avoid the slide rod 15. The diameter of the through hole 17 is smaller than the diameter of the spring 14, so that the spring 14 cannot pass through the through hole 17. The slide rod 15 is slidably connected to the through hole 17.

[0023] One end of the slide rod 15 is provided with a baffle 13, and one end of the spring 14 is blocked by the baffle 13. Therefore, the baffle 13 and the release sleeve 6 will compress the spring 14 when they are squeezed together. The diameter of the baffle 13 is larger than the diameter of the through hole 17, so that the baffle 13 cannot pass through the through hole 17.

[0024] The handle 5 has a through hole 9 in the middle, and the pull rod 12 is slidably connected to the through hole 9. A limiting ring 16 is provided on the outside of the through hole 9. The diameter of the limiting ring 16 is larger than the diameter of the through hole 9, so that the limiting ring 16 cannot pass through the through hole 9 and will be blocked by the through hole 9. This can limit the pull rod 12 and prevent the pull rod 12 from moving too far, causing the locking rod 10 to separate from the handle 5.

[0025] The release sleeve 6 has a first indicator 7 on its outer side, which indicates the direction of pulling the release sleeve 6 so as to release the lock on the handle 5. The upper cover 3 has a second indicator 8 on its outer side, which indicates the status of the handle 5.

[0026] Specifically, when the handle 5 needs to be turned, the release sleeve 6 is pulled outward. The release sleeve 6 cooperates with the baffle 13 to compress the spring 14. The release sleeve 6 drives the pull rod 12 to move away from the handle 5. The pull rod 12 pulls the locking rod 10 through the connecting rod 11, causing the locking rod 10 to move away from the third locking hole 19. When the limit ring 16 is pressed against the handle 5, preventing the release sleeve 6 from moving, the locking rod 10 has completely disengaged from the third locking hole 19, and the handle 5 is no longer locked. Then the handle 5 can be turned for operation. When the handle 5 is turned to the closed position, the release sleeve 6 is released, the spring 14 springs back to its original position, and the spring 14 pushes the release sleeve 6 to return to its original position. The release sleeve 6 causes the pull rod 12 to move closer to the handle 5. The pull rod 12, through the connecting rod 11, causes the locking rod 10 to move away from the handle 5. The locking rod 10 is engaged in the second locking hole 18, thus locking the handle 5. Even if the handle 5 is accidentally touched, the handle 5 cannot be turned.
