Body, circuit breaker handle, drive link, travelling gear and drive gear, arrange straight trough on the Shell of circuit breaker, circuit breaker handle sets
Put in straight trough, described drive link one end is connected with circuit breaker handle, other end bias is hinged and is arranged on travelling gear, institute
State travelling gear to be intermeshed with drive gear, it is characterised in that：The coincidence brake mechanism also includes extension spring, the breaker hand
Handle upper end is provided with connecting portion, and the drive link is provided with bolt near one end of circuit breaker handle, and one end of the extension spring is socketed in
On connecting portion, the other end is bolted on drive link.
The utility model is further arranged to：The connecting portion is provided with screw thread short circuit, and the extension spring passes through thread bush
The nut being connected on screw thread short circuit is fixed on circuit breaker handle.
The utility model is further arranged to：The air ring being socketed on connecting portion is provided between the nut and extension spring
Piece.
The utility model is further arranged to：The drive gear is fixed in rotating shaft, and the rotating shaft top is provided with just
In the rotation section for rotating the rotating shaft manually, drive gear band nutating gear is made by rotation section rotating shaft when manually operated
Rotate, travelling gear drives circuit breaker handle to complete breaker open operation or pull work again by drive link.
The beneficial effects of the utility model：The utility model changes circuit breaker handle and drive link in existing breaker
Between rigid connection mode, using the elastic connection way of extension spring form, change in existing breaker circuit breaker handle with
Wear away larger between drive link, stroke is non-adjustable and required precision that reduce the processing of connection member between the two, it is achieved that disconnected
Road device handle is adjustable with the stroke of drive link, it is steady to rotate smooth, speed, the advantages of wear and tear little, combined floodgate reliability is improved.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for the utility model to be described, but is not limited to scope of the present utility model.
As shown in Figure 1 to Figure 3, the coincidence brake mechanism of a kind of breaker, including Shell of circuit breaker 1, circuit breaker handle 2, passes
Lever 4, travelling gear 5 and drive gear 6, arrange straight trough 11 on the Shell of circuit breaker 1, circuit breaker handle 2 is arranged on straight trough
In 11,4 one end of the drive link is connected with circuit breaker handle 2, and other end bias is hinged and is arranged on travelling gear 5, described
Travelling gear 5 is intermeshed with drive gear 6, and the coincidence brake mechanism also includes that extension spring 3,2 upper end of the circuit breaker handle set
There are connecting portion 21, the drive link 4 to be provided with bolt 41 near one end of circuit breaker handle 2, one end of the extension spring 3 is socketed in company
In socket part 21, the other end is fixed on drive link 4 by bolt 41.The utility model changes breaker in existing breaker
Rigid connection mode between handle 2 and drive link 4, using the flexible resilient connected mode of 3 form of extension spring, improves existing disconnected
