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. 1-6, the present invention provides a technical solution: a brake separating device for a circuit breaker comprises a sliding switch 1, the circuit breaker is in a closing state when the sliding switch 1 is positioned above, the circuit breaker is in a breaking state when the sliding switch 1 is positioned below, the circuit breaker further comprises two fixing blocks 2, the two fixing blocks 2 are oppositely arranged on two sides of the sliding switch 1, the two fixing blocks 2 are fixedly connected to one side of the circuit breaker, sliding grooves are respectively formed in the inner sides of the two fixing blocks 2 (the inner side of the fixing block 2 refers to the side, contacted with the sliding switch 1, of the fixing block 2), a blocking assembly 3 is respectively arranged in the two sliding grooves in a sliding manner, limiting grooves are respectively formed in two sides of the inner wall of each fixing block 2, each limiting groove is of a T-shaped structure, each blocking assembly 3 comprises a blocking block 301, two sides of each blocking block 301 are respectively and fixedly connected with a limiting block 302, each limiting block 302 is of a T-shaped structure, the limiting blocks 302 of the T-shaped structures are matched with the limiting grooves of the T-shaped structures, the limiting groove does not penetrate through the fixed block 2, so that the blocking component 3 is ensured not to be completely separated from the fixed block 2, the blocking component 3 is convenient to reset, the blocking block 301 is provided with a first inclined surface and a second inclined surface (the first inclined surface is a lower inclined surface of the blocking block 301, the second inclined surface is an upper inclined surface of the blocking block 301), the sliding switch 1 passes through the first inclined surface and the second inclined surface in the sliding process, the sliding switch 1 is in contact with the first inclined surface when the sliding switch 1 is switched from the switching-off state to the switching-on state, the sliding switch 1 is in contact with the second inclined surface when the sliding switch 1 is switched from the switching-on state to the switching-off state, the inclination of the first inclined surface is larger than that of the second inclined surface, the larger the inclination of the inclined surface is, the smaller the contact area of the inclined surface and the sliding switch 1 is when the sliding switch 1 is pushed, the larger the effort required for pushing the sliding switch 1 is, and the better the effect of preventing accidental contact is, first inclined plane rubberizing has connect a rubber slab 5, rubber slab 5 also can provide certain resistance, the effect of preventing the mistake and touching has been improved, the inner wall of fixed block 2 and the direction that blocks between the subassembly 3 are elastic component 4 of fixedly connected with, elastic component 4 is towards slide switch 1's direction release elasticity, elastic component 4 includes the spring of two relative settings, the one end of two springs and the inner wall fixed connection of fixed block 2, the other end of two springs and the one side fixed connection who blocks subassembly 3, the spring mainly improves elasticity, it pushes away the position that is close to slide switch 1 to block piece 301.
