Detailed ways

Below in conjunction with accompanying drawing, the implementation of the present utility model is described in detail.

As shown in Figure 1, the utility model is an electronic lock refitted from an ordinary mechanical lock, which mainly consists of a mechanical lock, a motor 10, a power controller 9 and a remote control device. The mechanical lock adopts a three-plug anti-theft lock, which is mainly composed of a lock body 1, and a small dead bolt 2 and a double-plug dead bolt 3 are arranged in the lock body 1. There is a return spring on the small deadbolt 2 and is connected with the linkage plate 5; the rear end of the double-insert deadbolt 3 is installed on the moving plate 4 with the dial hole 6, and the above-mentioned linkage plate 5 is connected to the moving plate 4 to realize the small lock. The linkage between tongue 2 and double-insert deadbolt 3. Lockhole place is provided with a rotatable shift fork 17, and shift fork 17 stretches in the above-mentioned shifting hole 6, is used to stir mobile plate 4. The inboard of lock body 1 is also provided with a deadlock switch 8 that cooperates with small dead bolt 2, after lock body 1 is locked, close deadlock switch 8, small dead bolt 2 and double plug dead bolt 3 positions. As shown in Figure 2, the motor 10 adopts a stepper motor 10 or a DC geared motor 10, and the output shaft of the motor 10 extends into the lock hole, and a pick I11 is installed in the longitudinal shaft hole of the output shaft, and is fixed by a rivet; Sheet 111 cooperates with above-mentioned shift fork 1 7, and drives shift fork 1 7 to rotate. The motor 10 is controlled by a power controller 9, and can realize functions such as forward rotation, reverse rotation, and stop rotation. Lock body 1 is also provided with an auxiliary lockhole with lock core 12, and lock core 12 is toggled by key, as shown in Figure 3, the end of lock core 12 is provided with plectrum II13, and this plectrum II13 and A fork II 14 fits. The above-mentioned power supply controller 9 is provided with a control circuit composed of a remote control receiving circuit, a single-chip microcomputer and a power supply circuit, and is remotely operated by the remote control device. As shown in Figure 1, three limit switches and two emergency switches connected with the above-mentioned control circuit are also provided in the lock body 1, the limit switch I 17 is triggered by the above-mentioned deadlock switch 8, and the limit switch II 18 is triggered by the above-mentioned The moving plate 4 is triggered, and the limit switch III 19 is triggered by the above-mentioned linkage plate 5; the limit switch is used to detect and control the opening and closing state of the lockset to realize the automation of the lockset; the emergency switch I 15 and the emergency switch II 16 are controlled by the above-mentioned shift fork II 14 triggers, used to realize the opening and closing of the electronic lock with a key when the electronic lock fails.

When deadlock switch 8 is deadlocked, just trigger limit switch 117, at this moment power controller 9 does not do any corresponding, and electronic lock is in deadlocked state.

When unlocking, the motor 10 rotates in the forward direction, and the shift fork I 7 is moved by the paddle I 11 on the output shaft, and the shift fork I 7 moves the double-insert deadbolt 3 back to its position through the shift hole 6 on the moving plate 4. , drives small dead bolt 2, and the linkage plate 5 that is connected with it triggers limit switch III 19, and 9 locks of notice power controller have been opened.

When locking, the motor 10 reversely rotates, the shift fork 17 stirs the movable plate 4, and the movable plate 4 drives the double plug dead bolt 3 to move forward, until the movable plate 4 triggers the limit switch II 18, and notifies the power controller 9 that the lock has been completed. Be locked, stop motor 10 and rotate.

When the electronic lock breaks down and cannot be opened and closed by remote control, the key is inserted into the lock core 12, and when the key rotates forward, the plectrum II 13 of the lock core 12 drives the shift fork II 14 to trigger the emergency switch I 15, and now the motor 10 is forward. Rotate and open the lock, when the key is reversed, the plectrum II 13 of the lock core 12 drives the shift fork II 14 to trigger the emergency switch II 16, and now the motor 10 reversely rotates and locks the lock.
