Description of drawings
Fig. 1 is the structure front view of an embodiment of manual operating mechanism of breaker of the present invention;
Fig. 2 is the vertical view of manual operating mechanism of breaker shown in Figure 1;
Fig. 3 is the structure front view of another embodiment of manual operating mechanism of breaker of the present invention;
Fig. 4 is the vertical view of manual operating mechanism of breaker shown in Figure 3.
Embodiment
Referring to Fig. 1, Fig. 2, cooperate referring to Fig. 3, Fig. 4.Wherein, Fig. 1, Fig. 2 are the structural representation of an embodiment of manual operating mechanism of breaker of the present invention, and Fig. 3, Fig. 4 are the structural representation of another embodiment of manual operating mechanism of breaker of the present invention.Manual operating mechanism of breaker of the present invention is a kind of being installed between control cubicle door and the circuit breaker, can control the switch of control cubicle door and the operating mechanism of breaker closing separating brake simultaneously.On the operating grip of control cubicle door, be provided with the self-locking body that can carry out self-locking to the control cubicle door.Manual operating mechanism of breaker of the present invention comprises support 1, vertical shaft A, upright shaft B, link assembly C, link assembly D, bracket component 2, lock shaft 3 and steel wire rope 4.Support 1 is a U-shaped plate and frame structural member, be used to be installed on the circuit breaker and the weight of carrying a part of parts, vertical shaft A is installed in the floor below of this plate and frame support 1 and links to each other with operating grip on the control cubicle door by self-locking body, link assembly C, link assembly D and upright shaft B all are arranged on the base plate top of this plate and frame support 1, wherein link assembly C is fixed on the vertical shaft A and can rotates with vertical shaft A, upright shaft B is installed on the link assembly C and can rotates with link assembly C, link assembly D is installed on the upright shaft B and can links to each other with the upright shaft B rotation and with the circuit breaker handle transmission, bracket component 2 links to each other with lock shaft 3 orders and is arranged on the outside of plate and frame support 1, bracket component 2 and the control cubicle body weight that is fixedly linked and carries another part parts wherein, the outside that lock shaft 3 is installed in bracket component 2 is used for the switch of control cubicle door is controlled.One sleeve pipe 5 that passes through this side plate is installed on a side plate of U-shaped plate and frame support 1, the outer end of this sleeve pipe 5 and bracket component 2 are fixedly linked, steel wire rope 4 passes from this sleeve pipe 5, one end enters in the plate and frame support 1 and links to each other and can be driven by link assembly D with link assembly D, and the other end enters the bracket component 2 interior switches that can drive 3 pairs of control cubicle doors of lock shaft that link to each other with lock shaft 3 and controls.
The operation principle of manual operating mechanism of breaker of the present invention is, link assembly D is connected combined floodgate and the separating brake of controlling circuit breaker with circuit breaker handle, vertical shaft A is connected the Kai Heguan of control control cubicle door by self-locking body and the operating grip on the control cubicle door, bracket component 2 is installed on the control cubicle body, controls the Kai Heguan of control cubicle door once more with lock shaft 3.When the operating grip on the control cubicle door is in closing position, the self-locking body self-locking that vertical shaft A is connected with the control cubicle door, vertical shaft A ejects lock shaft 3 by link assembly C, axle B, link assembly D and steel wire rope 4 and pins the control cubicle door simultaneously.This manual-operating mechanism has double self-locking function.Compare with general manual operating mechanism of breaker, manual operating mechanism of breaker of the present invention has been avoided the relatively poor defective of self-locking device fail safe, and adopts steel cord structure, has improved processing safety greatly.
