Description

Technical Field

[0001] The utility model relates to the technical field of electronic locks, in particular to an emergency opening device for an electronic lock. Background Art

[0002] When the electronic locks such as the push-pull locks on the market are locked, after the door is closed, the sensor tongue is pressed into the lock body by the door frame, triggering the sensor tongue control switch. The control unit in the push-pull lock receives the door closing signal, and the drive motor drives the square tongue to pull the button to lock the square tongue. When the lock needs to be unlocked, the unlocking signal is sent to the sensor tongue through the handle or the button on the electronic lock, and the drive motor drives the square tongue to retract according to the unlocking signal to unlock the door. However, once the electronic control component of the electronic lock fails, the square tongue cannot be unlocked.

[0016] Example

[0017] like Figure 1-Figure 3An electronic lock emergency opening device is shown, comprising a lock housing 1, a bracket 2 is mounted on the lock housing 1, a handle 3 is mounted on the bracket 2, a movable locking block 4 is arranged between the handle 3 and the bracket 2, when the locking block 4 is located between the handle 3 and the bracket 2, rotating the handle 3 can drive the bracket 2 to rotate, thereby opening the door lock, when the locking block 4 is in the bracket 2, rotating the handle 3 cannot drive the bracket 2 to rotate, thereby failing to open the door lock;

[0018] An electronic lock assembly is provided on one side of the locking block 4, and an emergency opening assembly is provided below the electronic lock assembly. The electronic lock assembly includes an identity identifier 5 and a motor 6. The identity identifier 5 is installed above the lock housing 1. The identity identifier 5 can adopt a structure such as an electronic code device. A movable block 7 is installed inside the motor 6. The movable block 7 is located on one side of the locking block 4 and can push the locking block 4 to move.

[0019] like Figure 2 and Figure 3 As shown, the emergency opening assembly includes a rotating disk, and there are three rotating disks, namely a first rotating disk 8, a second rotating disk 9 and a third rotating disk 10, all of which are located outside the lock housing 1. The middle of the first rotating disk 8 is connected to one end of a first rotating rod 11, and the first rotating rod 11 passes through the lock housing 1 to connect to a first driving disk 12. The first rotating rod 11 is rotatably connected to the lock housing 1, and the second rotating disk 9 is connected to a second rotating rod 13, and the second rotating rod 13 is rotatably installed inside the first rotating rod 11. The third rotating disk 10 is connected to a third rotating rod 14, and the third rotating rod 14 is rotatably installed inside the second rotating rod 13. The ends of the second rotating rod 13 and the third rotating rod 14 are respectively connected to The second drive disk 15 and the third drive disk 16 are connected, and scale values ​​are provided below the lock housing 1, on the first rotating disk 8, the second rotating disk 9 and the third rotating disk 10. The first drive disk 12, the second drive disk 15 and the third drive disk 16 have drive grooves 17 on their sides. A drive rod 18 is provided on one side of the first drive disk 12, the second drive disk 15 and the third drive disk 16. The drive rod 18 is connected to a connecting rod 19.
