Detailed ways

Referring to Figures 1 to 12, an electronic lock clutch includes a bottom case 1 and a face cover 15. Inside the bottom case 1 are installed a rotating core 2 and a latch member 3 stacked up and down on the same axis. The rotating core 2 is used to connect Unblanking handle, bolt part 3 is used for connecting square shaft, and square shaft rotates, and just can drive dead bolt to stretch out lock door or retract to unlock. A latch tongue 4 and a latch 5 are installed between the rotating core 2 and the latch member 3. The latch 5 has two fixed positions, one is a locked position and the other is a clutch position. When the latch 5 is in the locked position, the corresponding In the clutch locking state, during the clutch locking state, the latch 5 is horizontal between the rotating core 2 and the latch member 3, and the latch member 3 rotates synchronously together when the rotating core 2 is in use. When the latch 5 is in the clutch position, it corresponds to the clutch separation state. During the clutch separation state, the latch 5 retracts into the latch member 3 and separates from the rotating core 2. When the rotating core 2 is rotated, the latch member 3 rotates asynchronously.

The latch 5 is connected with a return spring 50, and when the clutch is separated, the return spring 50 pops the latch 5 from the locked position to the clutch position, and the bottom shell 1 is equipped with a clutch mechanism and a drive block 8, the One end of the driving block 8 is connected with the clutch mechanism, and the other end is connected with an electric unlocking mechanism and a key unlocking mechanism, which can be unlocked electronically or with a backup mechanical key.

The clutch mechanism includes a first clutch shift block 6, a second clutch shift block 7 and a clutch guide rod 60, the latch 5 is provided with two, and the first clutch shift block 6 and the second clutch shift block 7 are installed on On the clutch guide rod 67, the first clutch block 6 and the second clutch block 7 are connected to one end of the drive block 8, driven by the drive block 8, the first clutch block 6 and the second clutch shift block 7 slide synchronously toward or against each other along the clutch guide rod 67, and the first clutch shift block 6 and the second clutch shift block 7 slide toward each other to press two latches 5 or one of the latches 5 into the Horizontal between the rotating core 2 and the latch 3, rotating the rotating core 2 can drive the latch 3 to open the door. The first clutch shifting block 6 and the second clutch shifting block 7 slide backwards, the latch 5 is released, and the back-moving spring 50 ejects the latch 5, and the second clutch shifting block 7 will not rotate when the lock cylinder is rotated, so the lock cannot be unlocked.

The bottom shell 1 is provided with a driving block guide rod 80, and the driving block 8 is installed on the driving block guide rod 80. Driven by the electric unlocking mechanism or the key unlocking mechanism, the driving block 8 moves along the The driving block guide rod 80 slides to drive the first clutch shifting block 6 and the second clutch shifting block 7 to move to realize clutch locking and separation.

The driving block guide rod 80 can rotate in the circumferential direction and cannot move axially.

The motor 9 is connected with a control circuit board, and the control circuit board is connected with a fingerprint identification device, an electronic card identification device, etc. After the control circuit board sends out an unlock command, the motor rotates forward, driving the first clutch shift block 6 and the second clutch shift block 7 moves in opposite directions to lock the clutch, and then after a preset time delay, the motor reverses again to drive the first clutch shift block 6 and the second clutch shift block 7 to move in reverse to separate the clutch.

The key unlocking mechanism includes a circular pusher 10, the circular pusher 10 is provided with an axial strip hole 11, and a screw 12 connected to the bottom shell 1 is installed in the strip hole 11, and the circular pusher 10 A round push spring 13 is installed on the front end of the front end, and a rotating dial 14 is connected to the rear end. The surface of the round pusher 10 in contact with the rotating dial 14 is an inclined plane, and the rotating dial 14 is connected with a dial 140 and a lock cylinder 141. Rotating the lock core 141 can drive the rotating block 14 to rotate and unlock. When the clutch is locked, the rotating block 14 rotates to push the circular pusher 10 to move axially, and the front end of the circular pusher 10 pushes the drive block 8 axis To move, the driving block 8 pushes the first clutch shifting block 6 and the second clutch shifting block 7 to move in opposite directions, presses the latch 5 into the clutch locking position, and turns the handle to unlock. After the unlocking is completed, the key is reversed to drive the rotation of the lock cylinder 141 rotates in the opposite direction, the plectrum 140 drives the rotating block 14 to rotate in the opposite direction, the circular push spring 13 bounces the circular push 10 back to the reset position, and at the same time, the coil spring 81 bounces the drive block 8 back to the reset position, so that the first clutch shift block 6 and The second clutch shifting block 7 moves in reverse, releasing the latch 5 .

The bolt 3 is provided with a bolt installation position 30, and the bolt installation position 30 is provided with a radial bolt hinge shaft hole 31, and the bolt 4 is provided with a bolt shaft hole 40, and the bolt hinge A bolt hinge shaft 41 is installed in the shaft hole 31 and the bolt shaft hole 40, a bolt spring 42 is installed between one end of the bolt bolt 4 and the top of the bolt installation position 30, and the rotating core 2 is set There are four rotating bayonet sockets 20 mutually arranged in a 90-degree circular arrangement. When in a free state, the latch tongue spring 42 ejects one end of the latch tongue 4 outward, so that one end of the latch tongue 4 extends into one of them. In the rotating bayonet 20, when the rotating core 2 is rotated in one direction, the protruding end of the oblique tongue 4 will be compressed and idling, which will not drive the bolt 3 to rotate. When the rotating core 2 is rotated in the opposite direction, the oblique tongue 4 will Can not be compressed, can drive bolt part 3 to rotate, and bolt part 3 drives square shaft to rotate, and dead bolt is stretched out lock door.

Both ends of the bolt 4 are respectively provided with a notch 43, and the bolt member 3 is provided with two through bolt spring mounting holes 33 corresponding to the notches 43 on the bolt 4. The spring 42 is installed in one of the oblique tongue spring mounting holes 33, and a spring pressing piece 34 pressing the top of the oblique tongue spring 42 is installed on the latch member 3, and the screw of the spring pressing piece 34 is removed. , you can remove the spring pressing piece 34, then take out the bolt spring 42 and put it into the other bolt spring installation hole 33, so that the direction of inclination of the bolt 4 is opposite, and you can adjust the function of opening the left door and opening the door right , The adjustment is simple and convenient.

The latch member 3 is provided with two latch holes 32 arranged at 90 degrees to each other, and the two latches 5 are installed in the two latch holes 32 respectively, and a limiting member 320 is installed on the latch member 3 to limit the position. Part 320 prevents the latch 5 from breaking away from the latch hole 32; the rotating core 2 is provided with four clutch clips 21 arranged at 90 degrees to each other, and in the locked position, one of the latches 5 is inserted into one of the clutch clips 21, or two latches 5 are inserted in two clutch detents 21 respectively.
