For convenience of explanation, it is assumed that the door 48 is in a closed state, and the driving member 739 of the locking driving device 617 is in a locked position (see FIGS. 4 and 5). In this state, the driving member 739 is The leg portion 753 is fitted into the fitting groove 37 of the outer side portion 26, and the operating device 20 is set in the locked state. Therefore, if the outer shaft barrel 32 is to be rotated by the outer operating member 171, the outer shaft barrel 32 interlocks the leg portion 753. The driving member 739 pivots. However, since the leg portion 753 of the driving member 739 is not engaged with the fitting groove 37 of the outer side portion 26, the outer shaft barrel 32 cannot be rotated by the outer operating member 171, so that the outer operating device cannot be operated. The outer operating member 171 of 20B operates the latch of the latching device 36 to the unlatched position (as shown in Fig. 10), and the door 48 remains in the closed state. It should be noted that, regardless of whether the driving member 739 is in the locked position or the unlocked position, if the inner operating member 159 of the inner operating device 20A is used to rotate the inner shaft barrel 24, the inner shaft barrel 24 will interlock the retracting member 34 and interlock the latch. The latch 38 of the device 36 is displaced from the upper latch position to the unlatched position.

Referring to FIG. 5, if the correct password is input by the external electronic device 173 and the internal electronic device 78 recognizes that the password is correct, the internal electronic device 78 outputs an unlock signal to the electric drive 40, causing the electric drive 40 to operate to drive the member. The 739 and the restricting member 811 are displaced to the unlocking position, and the leg portion 753 of the driving member 739 is separated from the fitting groove 37 of the outer side portion 26, so that the operating device 20 is set to the unlocked state, and the outer operating member 171 is further rotated to drive the driving member. 739 causes the leg portion 753 to press against the inner wall of the movable slot 33C to rotate the engaging cylinder 33 to interlock the retracting member 34 to move the latch 38 from the upper latch position (as shown in FIG. 5) to the unlatching position (as shown in FIG. 10). Shown).

Assuming that the incorrect password is input by the outside electronic device 173 and the internal electronic device 78 recognizes the password error or does not input any password, the inner electronic device 78 does not output a signal to the locking driving device 617, and the driving device of the locking driving device 617 The 739 is held in the locked position, so that the operating device 20 is kept in the locked state, and the outer shaft cylinder 32 is fixed and cannot be rotated, so that the outer operating member 171 cannot be used to displace the retracting member 34, and the latch of the latching device 36 is further removed. The 38 is held in the upper latch position, and the door 48 cannot be opened using the outer operating member 171.

The cross-sectional shape of the head 815 of the restricting member 811 of the locking drive device 617 coincides with the movable space 33A of the engaging cylinder 33, so that the inner surface defining the movable space 33A can support the smooth and stable sliding of the restricting member 811, and further through the restricting member The 811 support driver 739 and the sleeve 715 can be displaced along the axial direction of the inner portion 22, so that the process of displacing the driver 739 to the locked or unlocked position is less likely to cause interference, further ensuring that the operating device 20 of the door lock 10 is set once each time. Both the locked state and the unlocked state can be executed correctly.

In addition, each recess 255 of the inner fixing member 251 is engaged with each convex portion 23 of the inner portion 22, and the inner fixing member 251 passes through the two bolts 56 and the two fixing posts 76 in the through holes 57 of the two access openings 48. The screwing is such that the inner fixing member 251 cannot rotate relative to the door 48, and the inner fixing member 251 reinforces the torsional strength of the operating device 20 (the torsional force is generated when the inner and outer operating members 159, 171 are rotated during operation).

The basic teachings of this creation have been described, and many extensions and variations will be apparent to those of ordinary skill in the art. For example, there may be only one convex portion 23 of the inner portion 22, and only one recess 255 of the inner fixing member 251 corresponding to the convex portion 23, so that the convex portion 23 is fitted with the concave portion 255, the inner portion 22 As it is impossible to rotate relative to the inner fixing member 251, the inner fixing member 251 can still improve the torsional strength of the operating device 20.

The present invention disclosed in the specification is to be considered as illustrative and not restrictive. The scope of the present invention is defined by the scope of the appended claims, and is not intended to be limited by the scope of the invention.
