As shown in fig. 1 to fig. 3, fig. 1 is a schematic structural diagram of an intelligent lock structure provided by an embodiment of the present invention. The embodiment of the utility model provides an intelligent lock structure, lock face 30, handle 10 and handle locating part 20, handle 10 is rotationally installed on lock face 30; the handle limiting part 20 penetrates through the lock surface 30 to be connected with the handle 10, a bearing 21 is arranged on the periphery of the handle limiting part 20, the bearing 21 abuts against the lock surface 30, the handle limiting part 20 comprises a reversing part 22, the handle limiting part 20 is fixed on the lock surface 30 through the reversing part 22, a wire passing hole 23 is further formed in the handle limiting part 20, a wire passing groove 24 is formed in the handle limiting part 20 along the opening direction of the wire passing hole 23, and the wire passing hole 23 is arranged opposite to the reversing part 22. Thus, by arranging the bearing 21 between the lock surface 30 and the handle limiting part 20, the friction between the handle limiting part 20 and the lock surface 30 is greatly reduced by the rolling friction of the bearing 21 when the handle 10 is rotated, which is beneficial to improving the flexibility of the handle 10 when the handle 10 is rotated, and the handle 10 is not shaken. Meanwhile, the reversing piece 22 is arranged on the handle limiting piece 20, the handle limiting piece 20 is fixedly connected with the lock surface 30, and the reversing piece 22 is adjusted to rotate the left and right directions of the handle 10 and then fasten the reversing piece 22, so that the reversing adjustment of the left and right opening directions of the handle 10 can be realized. And the reversing piece 22 and the wire through hole 23 are oppositely arranged, so that when the handle 10 is reversed, the left and right reversing can be realized only by rotating the handle 10 and the handle limiting piece 20, and fingerprint lines cannot be extruded.

Specifically, the reversing element 22 is a reversing screw, a threaded hole is formed in the handle limiting element 20, and the reversing screw is in threaded connection with the lock surface 30 through the threaded hole. In practical application, the left and right direction of the handle 10 can be changed only by detaching the direction-changing screw and fastening the direction-changing screw after rotating the handle 10. And the threaded hole and the wire passing hole 23 are oppositely arranged, so that when the reversing screw is disassembled to adjust the left and right reversing of the handle 10, the handle 10 and the handle limiting part 20 rotate together, and the purpose of left and right reversing can be easily achieved without disassembling the handle 10.

Specifically, a torsion spring (not shown) is disposed around the handle stopper 20, and the torsion spring is fixed to the locking surface 30. The torsion spring is disposed between the locking surface 30 and the handle stopper 20, and the torsion spring abuts against the locking surface 30. The lock surface 30 is provided with two limiting members 31, the two limiting members 31 are respectively arranged on opposite sides of the lock surface 30, and two ends of the torsion spring respectively abut against side surfaces of the two limiting members 31. The torsion spring can be adjusted after the handle stopper 20 is assembled to the locking surface 30, so that the handle 10 can be adjusted, and the shake-free rotation of the handle 10 can be reduced. In practical application, the inner diameter of the torsion spring is larger than the outer diameter of the bearing 21, so that the bearing 21 is sleeved in the torsion spring, the whole intelligent lock is compact in structure, and space is saved.

The embodiment of the utility model provides a fingerprint lock is still provided, including fingerprint line, mainboard control module and fingerprint lock structure, fingerprint identification module sets up on handle 10, and mainboard control module sets up the one side of keeping away from handle 10 at jam face 30, and the fingerprint line is connected with fingerprint identification module and mainboard control module respectively. This prevents the finger print from being squeezed when the handle 10 is rotated, and thus protects the finger print.

Specifically, the fingerprint line is nested in the wire passing groove 24 and penetrates out of the wire passing hole 23. The fingerprint lock structure is applied to the fingerprint lock, and the fingerprint line can directly pass through the handle limiting part 20 to be connected with the mainboard module. The fingerprint line is through crossing line groove 24 and through-hole, can directly stretch out from the through-hole process from handle locating part 20 through not passing through clutch assembly, and when handle 10 rotated, the fingerprint line can remove in crossing line groove 24, had avoided the fingerprint line to force the twist simultaneously and lead to the fingerprint line twist-off when handle 10 drove handle locating part 20 and rotate, and the fingerprint lock uses and breaks down.

It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
