In practical use, the sleeve 50 is an optional component, the sleeve 50 does not need to be arranged when the diameter of the jack 31 is basically consistent with or slightly different from that of the rocker hole 11, and the sleeve 50 is preferably arranged when the diameter of the jack 31 is greatly different from that of the rocker hole 11, so that the whole rocker hole 11 is adjusted, and the whole rocker hole 11 is ensured to be matched with the size of a rocker.

The operation process of the rocker hole locking lockset in the embodiment is as follows:

the principle of electric unlocking is as follows:

the operator presses the button 90 to send an unlocking instruction, and after receiving the feedback confirmation of the non-electrical information of the grounding switch detection circuit through the control circuit 70, the operator controls the driving motor to execute the unlocking instruction. If the disconnecting link detection circuit displays electrification, an indicator lamp buzzer gives an alarm prompt, at the moment, the driving motor does not act, the lockset cannot be opened, and the rocker cannot be inserted to operate the grounding disconnecting link;

during the unblock action, driving motor drives driving gear 23 corotation, driving gear 23 rotates and can drive driven gear 24 through gear pair transmission and rotate reversely, protruding post 241 on driven gear 24 can move in the spout 211 of latch member 21, and extrude the lateral wall of spout 211 thereby drive latch member 21 and move towards keeping away from rocker hole 11 direction, when latch member 21 breaks away from rocker hole 11 completely, no longer shelter from behind rocker hole 11, at this moment, driven gear 24 rotates 90, drive protruding 243 relative in drive slot 242 empty stroke rotation 90 in, driven gear 24 rotates, urgent unblock pivot 62 is static, in order to dodge urgent unblock pivot 62. The magnetic member 80 on the locking member 21 triggers the corresponding sensing member, and the control circuit 70 controls the driving motor to stop rotating, so that the locking member 21 is completely withdrawn from the rocker hole 11.

At this time, the operator sequentially passes the rocker through the rocker hole 11 and the insertion hole 31, the rocker presses the ball structure of the latch 41, the latch 41 is pushed to overcome the elastic force of the reset member 43 and disengage from the insertion hole 31, the other end of the latch 41 presses the spring and switches the state of the trigger switch 42, and the control circuit 70 thereby knows that the rocker is switched to the insertion state.

Electric locking principle:

after the grounding knife switch is operated by an operator, the rocker is pulled out, the stop pin 41 is separated from the trigger switch 42 under the elastic force of the reset piece 43 and is restored to the initial position, the control circuit 70 obtains state switching information and then automatically controls the driving motor to rotate reversely to perform locking operation after a period of time is delayed, the locking process is basically opposite to the unlocking process, and the description is omitted.

Emergency unlocking principle:

when the control circuit 70 controls the motor to fail, an operator inserts a mechanical key into the emergency unlocking lock cylinder 61 and reverses the key, the emergency unlocking lock cylinder 61 drives the emergency unlocking rotating shaft 62 to reverse, one end of the emergency unlocking rotating shaft 62 drives the driven gear 24 to reverse by pressing the driving protrusion 243 of the driving groove 242, the driven gear 24 rotates to drive the driving gear 23 to rotate forward by gear pair transmission, meanwhile, the convex column 241 on the driven gear 24 can move in the sliding groove 211 of the locking piece 21 and press the side wall of the sliding groove 211 to drive the locking piece 21 to move towards the direction far away from the rocker hole 11, when the locking piece 21 is completely separated from the rocker hole 11 and does not shield the rocker hole 11, at this time, the driven gear 24 rotates 90 °. An operator rotates forwards by 90 degrees to reset the emergency unlocking lock cylinder 61 and extracts the mechanical key, and the emergency unlocking rotating shaft 62 is reset by 90 degrees in a forward rotation mode relative to the hollow stroke in the driving groove 242, namely the driven gear 24 is static, and the emergency unlocking rotating shaft 62 moves to avoid the driven gear 24. At this time, the operator can insert the rocker to operate the earthing knife switch.

The emergency locking process is basically the same as the emergency unlocking process, and is not described again.

And (3) exception problem processing:

1. pressing button 90 detects that the earthing switch is not electrified, and if the rocker is not inserted after the locking member 21 is opened: after a certain delay, the blocking member 21 will be reset; manual advancing back of the closure member 21 may also be achieved by depressing the button 90 again;

2. after the earthing knife-switch is operated, the rocker is pulled out, and the rocker is inserted again before the lockset is unlocked, and the detection component 40 is triggered: each time the detection assembly 40 is released, i.e. the rocker is pulled out, the delay timing is carried out as the initial moment of the delay locking;

3. after the grounding switch has been operated, the rocker does not completely pull out the lock, i.e. stops in a position in which it can block the blocking member 21, and the triggering of the detection assembly 40 has been released: the lockset carries out locking action after a certain time delay, but the locking piece 21 is blocked by the rocker and cannot be closed, the indicator light buzzer carries out alarm prompt, the lockset does not become a locking state and stops acting after being repeatedly carried out for three times, if the lockset needs to be recovered, the rocker is pulled out, the button 90 is pressed, the locking action can be carried out again, and the locking state is recovered;

4. button 90 will be deactivated upon detection of rocker insertion by detection assembly 40;

5. the earthing knife-switch is electroless, and the button 90 is pressed and the lock can not be unlocked: the emergency unlocking key is used for rotating to unlock, the state of the lock is changed, the grounding switch detection circuit is activated, whether the grounding switch is electrified or not is judged, and the emergency unlocking key can normally complete unlocking if no electricity exists;

6. the earthing knife-switch has electricity, uses the urgent unlocking key to unlock: when the state of the lock is changed, the grounding switch detection circuit is activated to judge whether the grounding switch is electrified or not, the control circuit 70 sends an instruction to enable the lock to perform locking action, the lock performs locking and drives the emergency unlocking key to rotate reversely, and meanwhile, the indicator lamp buzzer performs alarm prompting.

It should be noted that, a plurality in the above embodiments means at least two.
