Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-8, the present invention provides a technical solution: a limiting closing device for a circuit breaker, the circuit breaker comprises a sliding switch 1, the sliding switch 1 has an opening position and a closing position, the limiting closing device comprises an extension block 2 and two blocking plates 3, one side of the extension block 2 is fixedly connected with one side of the sliding switch 1, the two blocking plates 3 are fixedly connected with one side of the circuit breaker, both sides of the extension block 2 are provided with a limiting rebound component 4, when the sliding switch 1 is at the closing position, the blocking plates 3 block the limiting rebound component 4, when the sliding switch 1 is at the opening position, the sliding switch 1 can be directly closed, the limiting rebound component 4 comprises two circular mounting grooves 401, the two circular mounting grooves 401 are respectively arranged at both sides of the extension block 2, a movable block 402 is arranged inside the circular mounting groove 401 in a sliding manner, the movable block 402 slides inside the circular mounting groove 401, a spring 403 is fixedly connected between the bottom of the inner wall of the extension block 2 and the movable block 402, the spring 403 releases elastic force towards the direction of the movable block 402, one side of the movable block 402 is fixedly connected with a fixture block 404, one side of the blocking plate 3 is provided with a circular through hole, the circular through hole is matched with the movable block 402, the diameter of the circular through hole is larger than that of the movable block 402, the positions of the two circular mounting grooves 401 are fixedly connected with a limiting ring 405 with a circular ring structure, the inner diameter of the limiting ring 405 is smaller than that of the fixture block 404, the inner diameter of the limiting ring 405 is smaller than that of the movable block 402, so that the movable block 402 can be blocked, the movable block 402 is prevented from being separated from the circular mounting groove 401, the fixture block can not be influenced to be popped out of the circular mounting groove 401 of the fixture block 404, the fixture block 404 is in a cylindrical structure, further, the edge of one end of the fixture block 404 is a round angle, the edge of the round angle can be better matched with the circular through hole, the fixture block 404 can be conveniently clamped into or separated from the circular through hole, and further, one end of the fixture block 404 is in a hemispherical structure, the advantages of the hemispherical structure are the same as above, and the effect is more excellent.
