When the shaft 2511 of the motor 251 rotates, the clutch 26 can be driven by the first operating element 24. The first position where the latch head 61 cannot be actuated is moved to the second position where the first operating element 24 can actuate the latch head 61, and when the shaft 2511 of the motor 251 rotates in the opposite direction, the clutch can be driven The piece 26 moves from the second position to the first position.

As shown in Figures 1 to 3 and Figures 7 to 12, after the door 8 is integrated as a whole, when the operator turns the first operating element 24 under normal conditions, the clutch 26 is located at the first position, that is, the The clutch 26 is engaged with the groove 285 of the driving seat 28, that is, the recess 263 of the clutch 26 does not overlap the groove 285 of the driving seat 28, so the operator cannot rotate the first operating element 24 to drive the latch 6 At this time, the supporting portion 284 of the driving seat 28 touches the first micro switch 51; if the first operating element 24 is to be used for unlocking or locking, the operator directly inputs a value from the input device 22 With the correct password, the signal control unit can drive the shaft 2511 of the motor 251 to rotate, and the clutch 26 will also rotate about 180 Degree, the clutch member 26 is rotated from the first position (as shown in FIG. 8) engaged with the groove 285 of the driving seat 28 to the second position (as shown in FIG. 9) not engaged with the groove 285 of the driving seat 28, That is, the clutch 26 is located at a position where the recess 263 and the groove 285 of the driving seat 28 overlap; at this time, the signal processing unit will provide a delay time to make the motor 251 inactive, and the clutch 26 is stationary and ready for operation By operating the first operating element 24 in the counterclockwise direction shown in FIG. 10, the first operating element 24 is moved from an initial position to an operating position, and the driving seat 28 will follow the first operating element 24 to rotate, One of the two driving parts 287 of the driving seat 28 drives one of the two driven parts 276 of the transmission member 27, and then drives the rod 237 to drive the latch head 61 to retract or extend; as shown in FIGS. 2 and 11 As shown, when the operator releases the first operating element 24, and moves the first operating element 24 from the operating position to the initial position, the first operating element 24 and the driving seat 28 will be affected by the elastic element 279 When the driving seat 28 returns to the unrotated position, any driving part 287 of the driving seat 28 will not drive any driven part of the transmission member 27. 276, so the rod 237 will not follow the rotation because the first operating element 24 and the driving seat 28 return to their original positions, and the latch head 61 will not be retracted or extended; because the rod 237 is additionally One end is connected to the second operating element 42 of the second lock body 4, so when the latch head 61 is retracted or extended, the second micro switch 44 will transmit a signal to the signal processing unit to inform the signal change, plus After the driving base 28 returns to the initial position, the supporting portion 284 of the driving base 28 is aligned again and touches the first micro switch 51, the first micro switch 51 will transmit a signal to the signal processing unit to inform the driving base 28 and After the first operating element 24 has been reset, the signal control unit will interrupt the delay time and drive the shaft 2511 of the motor 251 to rotate in the opposite direction. The second position where the groove 285 of the driving seat 28 is not engaged (as shown in FIG. 11) is rotated to the first position where the groove 285 of the driving seat 28 is engaged (as shown in FIG. 12), that is, the clutch The member 26 is located at a position where the recess 263 does not overlap the groove 285 of the driving seat 28; when the first operating element 24 is operated, due to the engagement of the clutch member 26 with the groove 285 of the driving seat 28, the first The operating element 24 cannot drive the latch head 61, but if an external force is used to operate the first operating element 24, the external force used for the first operating element 24 is greater than the ring element 292 and the first operating element 24 or the When the friction force of the driving seat 28 is applied, the first operating element 24 will rotate idly relative to the driving seat 28 and the base 21.

As shown in FIG. 13, when the clutch 26 rotates with the shaft 2511 of the motor 251, one of the two blocked portions 267 of the protrusion 266 of the clutch can abut against the protrusion 223 of the base 21 in a timely manner. One of the two blocking parts 224 is used for positioning the clutch 26 to ensure that the clutch 26 rotates to a proper position.

As shown in Figures 2, 3 and 7, the lock core 232 of the lock set 23 is directly connected to the rod 237, so the operator uses a correct key (not shown in the figure) to operate the lock set 3 in any situation. , Can drive the latch head 61 to retract or extend the latch 6; the second operating element 42 is directly connected to the rod 237, so the operator can drive the second operating element 42 in any situation The latch head 61 retracts or extends the latch 6.
