Referring to fig. 9 to 11, the shaft locking mechanism is located below the profiling handle 1, and includes a shaft locking body 9, a motor clamping seat 10, a motor 11, a retractable pin 12 and a spring 13. The lock shaft body 9 is a stepped cylinder with a large upper diameter and a small lower diameter, the lock shaft body 9 is provided with an axial motor cavity 901, the bottom of the motor cavity 901 is provided with a radial pin groove 902, one end of the pin groove 902 forms a through hole 903 on the lock shaft body 9, and the other end is closed. The retractable pin 12 is placed in the pin slot 902, and the spring 13 is disposed between the tail end of the retractable pin 12 and the closed end of the pin slot 902 (i.e. the side wall of the lock shaft body 9), so that when the retractable pin 12 moves in the pin slot 902, the head end of the retractable pin 12 can extend or retract from the through hole 903. Referring to fig. 8, the motor 11 is a micro M10 motor and is powered by the battery module 8. The head end of the motor 11 is inserted downwards into the motor cavity 901. The head end of motor 11 is connected with a rotor 15, sets up an eccentric deflector rod 14 that rotates on rotor 15, as shown in fig. 12, sets up a notch 1201 in the middle part of telescopic pin 12, and after motor 11 inserted motor chamber 901, eccentric deflector rod 14 that rotates stretched into notch 1201, and eccentric deflector rod 14 that rotates and notch 1201's lateral wall butt, stirs telescopic pin 12 through the rotation of motor 11, and the setting of spring 13 can make stretching out of telescopic pin 12 more rapidly. Set up two protruding card ears 904 in the top of motor chamber 901, set up on the motor cassette 10 with card ear 904 complex groove, motor cassette 10 is through calorie ear 904 and lock shaft body 9 fixed connection to motor cassette 10 card is established at the tail end of motor 11, and the shell cooperation with motor 11 makes motor 11 itself can not rotate. The motor clamping seat 10 and the top of the lock shaft body 9 form a flat surface which is fixedly connected with the bottom end of the columnar body 101 of the profiling handle 1.
A locking hole 403 is formed in the side wall of the handle fixing support 4, after the locking shaft mechanism is inserted into the shaft cavity 402, the locking hole 403 corresponds to the through hole 903 in the locking shaft body 9, when the telescopic pin 12 extends out of the through hole 903, the telescopic pin is clamped into the locking hole 403, so that the locking shaft mechanism cannot rotate, and when the telescopic pin 12 retracts, the locking between the locking shaft mechanism and the handle fixing support 4 is released, and the locking shaft mechanism can be rotated. The tail end of the lock shaft body 9, that is, the tail end of the lock shaft mechanism, is a section of square shaft 905, the tail end of the handle fixing support 4 is provided with a shaft hole, and the tail end face of the handle fixing support 4 is provided with a limit boss 404. The square shaft 905 is firstly sleeved with a rotation limiting plate 5 after extending out of the shaft hole, then is sleeved with a locking plate 6, and a screw is screwed on the shaft end of the square shaft 905 to enable the rotation limiting plate 5 and the locking plate 6 to be incapable of being separated from the square shaft 905. One section recess 501 is seted up to the axial of rotating limiting plate 5 and is cooperated with spacing boss 404, when the lock shaft mechanism rotates promptly, drive and rotate limiting plate 5 and rotate, both sides through rotating recess 501 on the limiting plate 5 lean on when leaning on with the both sides of spacing boss 404, can restrict lock shaft mechanism and rotate further, rotate the setting of recess 501 and spacing boss 404 on the limiting plate 5 and preferably can be the rotation restriction that forms 180 degrees, use locking position (locking hole 403 and the through-hole 903 position on the lock shaft body 9 is aimed at) anticlockwise and clockwise to rotate 90 degrees respectively for the limit. Therefore, the phenomenon that the rotation angle of the lock shaft mechanism is too large can be avoided, and a user can conveniently determine the locking position and the unlocking position.
The working principle of the hidden knob fingerprint lock mechanism is as follows: when the door is closed, the eccentric rotating shift lever 14 at the head of the motor 11 releases the telescopic pin 12, the profiling handle 1 is operated to rotate, the profiling handle 1 drives the lock shaft mechanism to rotate, when the through hole 903 on the lock shaft body 9 is opposite to the locking hole 403, the telescopic pin 12 extends under the action of the force of the spring 13 and is clamped into the locking hole 403, the lock shaft mechanism is locked with the handle fixing support 4, the lock shaft mechanism cannot continue to rotate, the profiling handle 1 cannot continue to rotate, and at the moment, the lock plate 6 is rotated to the locking position to be locked with the corresponding lock structure on the safe box, as shown in fig. 5, 6, 7 and 13. When the door is opened, the fingerprint module 2 recognizes the fingerprint and then controls the motor 11 to rotate, the eccentric rotating shift lever 14 pushes the telescopic pin 12 backward, the spring 13 is compressed, and the telescopic pin 12 retracts from the locking hole 403. At this time, the profiling handle 1 can be rotated, the profiling handle 1 drives the lock shaft mechanism to rotate clockwise or counterclockwise until the lock shaft mechanism cannot rotate due to the abutting of the rotation limiting plate 5 and the limiting boss 404, so that the lock plate 6 is separated from the lock structure on the safe box to complete unlocking, as shown in fig. 1, fig. 3, fig. 4 and fig. 14.
