The basic style of the traditional ball lock is that the outer lock and the inner lock are symmetrically arranged inside and outside the door and connected by a specific structure. In the unlocked state, the door can be opened by directly turning the outer lock or the inner lock. When a person is inside the door, the door can be locked by pressing the corresponding position of the inner lock and unlocked by turning the inner lock. When a person is outside the door, a key is needed to lock and unlock the door at the outer lock. The ball lock is mainly used on the door of a secondary space such as a bedroom. Although there are not many scenes where family members need to lock the door, it is inevitable that there will be a need for private space. When facing a locked room, the first reaction of the person outside the door is often to ask the person inside the door to open the door, which is bound to disturb the person inside the door.

[0031] The working principle of the ball lock outer lock with adjustable unlocking mode of the utility model is as follows: the outer lock is fixed to the outside of the predetermined installation position of the door, and the matching inner lock is fixed to the inside of the predetermined installation position of the door. At this time, the square axis 3 passes through the door, and the inner ends of the square axis 3 and the flat axis 2 are both located inside the inner lock. In the setting of the ball lock to which the outer lock belongs, a paddle is arranged at the center position of the matching inner lock, and the paddle can be adjusted between the initial, middle and final positions by twisting. When the paddle passes through the initial, middle and final positions in turn, the positioning head 29 is engaged with the first hole 24, the second hole 26 and the third hole in turn. When the positioning head 29 is engaged with the first hole 24, the second hole 26 or the third hole, the corresponding Hall sensor is used to The main board 31 executes the corresponding instructions. When the paddle is in the initial position, the ball lock is not locked. The door can be opened by holding the upper shell 4 and the lower shell 1 and turning them. If the person inside the door wants to be alone and allow others to enter the door when necessary, the paddle is turned to the middle position. During this process, the paddle drives the flat shaft 2 and the rotating head 28 to rotate as a whole. Under the action of the first spring, the positioning head 29 slides steadily along the slide groove 25 until it is engaged with the second hole 26. At this time, the person outside the door only needs to press the finger on the fingerprint module 5 position to unlock the door. If the person inside the door wants to be alone and does not want to be disturbed, the paddle is turned to the final position. At this time, the positioning head 29 is engaged with the third hole. Even if the person outside the door presses the finger on the fingerprint module 5 When the outsider cannot unlock the door by fingerprint, the reminder mechanism of the ball lock of the external lock is triggered, that is, "the insider does not want to be disturbed temporarily, please wait". If the outsider is worried about the safety of the insider, or has other reasons to enter the door, the outsider can still unlock the door with the key. The process of unlocking the door by fingerprint is as follows: after the fingerprint recognition is passed, the main board 31 starts the motor 12, and the output shaft of the motor 12 drives the rotator 19 to rotate. When the polarity of the second magnet and the third magnet directly below it is the same, the second magnet pushes the third magnet and the electric bolt 23 to move vertically downward as a whole until the pin shaft 21 is plugged into the corresponding slot 18. At this time, the upper shell 4 and the lower shell 1 are held and rotated to make the card holder 1 3. The square shaft 3 rotates accordingly and the lock is unlocked smoothly. The fingerprint can be recognized again to make the output shaft of the motor 12 rotate and the electric bolt 23 reset. The process of unlocking with the key is that the key drives the core shaft 14 to rotate in the core shell 16, and the rotating piece 15 rotates with the core shaft 14. The end of the rotating piece 15 presses down the manual bolt 17 and makes the manual bolt 17 plug into the corresponding slot 18. At this time, hold the upper shell 4 and the lower shell 1 and rotate them to make the base 13 and the square shaft 3 rotate accordingly and unlock smoothly. Reset the core shaft 14 with the key, and the second spring can reset the manual bolt 17. When the pin shaft 21 and the electric bolt 23 are not plugged into the slot 18, even if the outsider rotates the upper shell 4 and the lower shell 1, he cannot unlock the door.
[0032] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
