Referring to fig. 1 to 3, the utility model discloses a fingerprint ball lock of embodiment includes: the front ball lock body 100, the lock core structure 200 is arranged in the front ball lock body 100, the key hole 110 communicated with the lock core structure 200 is arranged on the front ball lock body 100; a rear ball lock body 300; a connecting rod 400 having one end connected to the rear ball-lock body 300 and the other end extended into the front ball-lock body 100 and capable of being connected to the lock cylinder structure 200; a cover 500 provided in the front ball lock body 100 and movable with respect to the front ball lock body 100 to cover the key hole 110 or expose the key hole 110; the fingerprint identification module 600 is disposed on the cover 500 and can control the locking or unlocking of the lock cylinder structure 200.

The fingerprint ball lock with the structure is characterized in that the cover body 500 is arranged on the front ball lock body 100, the cover body 500 is used for moving relative to the front ball lock body 100 to shield or expose the key hole 110, the cover body 500 shields the key hole 110, dust accumulation in the key hole 110 can be avoided, concealment of the key hole 110 can be improved, safety of the fingerprint ball lock is improved, a fingerprint unlocking function is achieved through the fingerprint identification module 600 on the cover body 500, and unlocking and locking can be achieved through fingerprints even when a user forgets to take a key.

Referring to fig. 2 and 3, in some embodiments of the present invention, the key hole 110 is formed in the front end surface of the front ball lock body 100, and the cover 500 is rotatably mounted on the front end surface of the front ball lock body 100 by a first pivot 510, wherein the first pivot 510 is offset from the rotation axis of the front ball lock body 100. It can be understood that, since the first pivot 510 is offset from the rotation axis of the front ball lock body 100, when the door needs to be opened by using the key, the user can grasp the cover body 500 and rotate to expose the key hole 110 on the front end face of the front ball lock body 100.

Referring to fig. 3 and 4, in some embodiments of the present invention, in order to prevent the cover 500 from moving due to a touch mistake, and thus expose the key hole 110, a limiting mechanism is disposed between the front ball lock body 100 and the cover 500 for limiting the rotation of the cover 500 relative to the front ball lock body 100.

Referring to fig. 4, in some embodiments of the present invention, the limiting mechanism includes a resilient member 710 disposed between the front ball lock body 100 and the cover body 500, and the resilient member 710 is used to urge the cover body 500 against the front ball lock body 100. The cover 500 abuts against the front ball lock body 100 by the elastic member 710, and the friction force between the cover 500 and the front ball lock body 100 prevents the cover 500 from being displaced relative to the front ball lock body 100. Of course, in other embodiments, the limiting mechanism may be replaced by a snap structure that is disposed between the front ball-lock body 100 and the cover body 500 and is detachably connected.

Referring to fig. 3 and 4, in some embodiments of the present invention, the first pivot 510 is disposed on a side portion of the cover 500 and is parallel to a rotation axis of the front ball lock 100, the front ball lock 100 is provided with a shaft hole 120 for the first pivot 510 to pass through, an end portion of the first pivot 510 away from the cover 500 is detachably connected with an anti-slip portion 520, the elastic member 710 is a spring member passing through the first pivot 510, and two ends of the spring member respectively abut against the anti-slip portion 520 and the front ball lock 100. In this embodiment, the anti-slip portion 520 is an anti-slip nut screwed on the end of the first pivot 510, and the elastic member 710 is disposed in a manner that helps to simplify the structure of the limiting mechanism, and reduce the manufacturing cost and the assembly difficulty of the fingerprint ball lock.

Referring to fig. 4, in some embodiments of the present invention, the limiting mechanism includes a ring-shaped groove 720 disposed around the rotation axis of the front ball lock body 100 and a ring-shaped portion 730 engaged with the ring-shaped groove 720, one of the ring-shaped groove 720 and the ring-shaped portion 730 is disposed on the front ball lock body 100, and the other is disposed on the cover body 500. In the present embodiment, the annular groove 720 is formed in the front ball lock body 100, the annular portion 730 is formed in the cover body 500, and since the first pivot 510 is offset from the rotation axis of the front ball lock body 100, the cover body 500 cannot be directly rotated with respect to the front ball lock body 100 in a state where the annular groove 720 and the annular portion 730 are combined. It should be noted that, when it is required to drive the cover 500 to rotate, a user can first hold the cover 500 and move the cover in a direction away from the front ball lock 100, at this time, the elastic member 710 is compressed, the first pivot 510 is still located in the shaft hole 120, and after the ring portion 730 is separated from the ring groove 720, the cover 500 can rotate relative to the front ball lock 100 to expose or block the key hole 110.

Referring to fig. 4, in some embodiments of the present invention, an angle limiting structure 800 is disposed between the front ball-lock body 100 and the cover body 500 to limit the rotation angle of the cover body 500. The angle limiting structure 800 can limit the cover 500 at a predetermined angle, and prevent the cover 500 from excessively rotating when the key hole 110 needs to be exposed, thereby preventing the influence on the convenience of use.

Referring to fig. 3 and 4, in some embodiments of the present invention, the angle limiting structure 800 includes a positioning protrusion 810 disposed on a side portion of the first pivot 510, the front ball-lock body 100 is provided with a shaft hole 120 for the first pivot 510 to pass through, and an inner wall of the shaft hole 120 is provided with a plurality of stop limiting surfaces 820 capable of abutting against the positioning protrusion 810. When the first pivot 510 rotates clockwise or counterclockwise in the axial hole 120 by a certain angle, the positioning protrusion 810 abuts against a stop limiting surface 820, so as to prevent the first pivot 510 from rotating relative to the axial hole 120.

Referring to fig. 3 and 4, in some embodiments of the present invention, an accommodating space is defined between the cover 500 and the front ball lock body 100, and the fingerprint identification module 600 includes a control circuit board 610 disposed in the accommodating space and a fingerprint identification part 620 connected to the control circuit board 610. It should be noted that the control circuit board 610 and the fingerprint identification part 620 are both disposed on the cover body 500, and in a state where the key hole 110 is shielded by the cover body 500, the control circuit board 610 and the fingerprint identification part 620 can be located in the accommodating space, so as to prevent the control circuit board 610 and the fingerprint identification part 620 from being exposed to moisture and being electrochemically corroded.

Referring to fig. 2, in some embodiments of the present invention, the fingerprint recognition module 600 is disposed on the front end surface of the cover 500. It should be noted that, when the fingerprint identification module 600 is disposed at the front end of the cover 500, the palm of the user will not cling to the fingerprint identification module 600, so as to avoid unnecessary damage caused by applying force to the fingerprint identification module 600.

Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications and substitutions are included in the scope defined by the claims of the present application.
