Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Embodiment 1:
As shown in Figs 1-4, the embodiments of the present invention 1 provide a kind of mechanical interlocking dress of circuit breaker operation mechanism
Set, including with one-to-one two operating sticks 1 of two circuit breaker operation mechanisms to be interlocked, connecting rod 2, connecting lever 3 and pass
Lever 4；The operation handle 101 of the circuit breaker operation mechanism passes through the corresponding operating stick 1 and circuit breaker operation mechanism sheet
Body 102 connects, and two operating sticks 1 respectively penetrate the both ends of the connecting rod 2, and can freely turn in the connecting rod 2
Dynamic, the quantity of the connecting lever 3 is two and corresponds with the operating stick 1, is offered and corresponding operation on the connecting lever 3
The connecting hole that bar 1 matches, the operating stick 1 penetrate in corresponding connecting hole, and are connected together with corresponding connecting lever 3, and two
The connecting lever 3 is respectively arranged at the two sides of the connecting rod 2, and two connecting levers 3 turn with the both ends of the drive rod 4 respectively
Dynamic connection.
The mechanical interlocks of the offer of the utility model, its working principles are as follows: when in two chain breakers, one
When a breaker needs to close, corresponding operation handle 101 is rotated, operation handle 101 is transmitted rotating torque by operating stick 1
To circuit breaker operation mechanism, and then realize closing for corresponding breaker.After the breaker closes, when being rotated due to operating stick 1
Corresponding connecting lever 3 is driven to rotate, connecting lever 3 drives another 3 opposite direction of connecting lever to rotate by drive rod, so that another manipulator
The rotation of 101 opposite direction of handle, and then realize the disconnection of another breaker.Realize the interlocking of two circuit breaker operation mechanisms.
The interlocking of be arranged along the vertical direction two circuit breaker operation mechanisms, and structure letter may be implemented in the utility model
Single practical, high reliablity.
Preferably, as shown in Figs 1-4, the operating stick 1 is square pole, and the connecting hole is to match with the square pole
Square hole.
