DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(13) Referring to FIGS. 1-6, a first embodiment of the present invention includes: an electronic lock body 10, having a housing cavity 11 and a latch bolt 12, with a pair of first screw holes 14 provided on the top (or plate-facing) surface of the electronic lock body 10 and respectively positioning on opposing sides of the housing cavity 11; a plate 20, with a pair of first positioning holes 23 each provided at a position to align with a corresponding first screw hole 14, using plate screws 13 to engage with the first screw hole 14 of the electronic lock body 10, and beside covering the electronic lock body 10, the plate extended upward and downward to the opening side of the plate 20, further having a gap 21 for exposing the housing cavity 11 and the latch bolt 12; a pair of second positioning holes 24 are provided to the front of the pair of first positioning holes 23 and formed through the plate 20; a fixed adjust element 30A, with a pair of second screw holes 34 each provided at a position to align with a corresponding second positioning hole 24, using adjust (or adjusting) screws 22 to engage with the second positioning hole 24 at a bottom (or body-facing) surface of the plate 20, the middle section of the fixed adjust element 30A is arranged at a rod 31 arranged below the gap 21, and a fixed channel 32 is formed in the middle section; and an active adjust element 40A, having a sleeve slot 41 positioned relative to the rod 31, and having a ramp element 42A corresponding to the latch bolt 12, the active adjust element 40A being sleeved between the bottom surface of the plate 20 and the rod 31; the ramp element 42A having an active channel 43 corresponding in position to the fixed channel 32, and the width of the active channel 43 is narrower than the width of the fixed channel 32.

(14) With the feature disclosed above, referring to FIGS. 79, after installing the plate 20 on a door frame 50 so that the housing cavity 11 is aligned with the latch bolt of the mechanical lock box, if the active channel 43 is not aligned with the dead latch of the mechanical lock box, then one may loosen the adjusting screw 22 (the adjusting screw 22 is not removed) to enable the active adjust element 40A and the fixed adjust element 30A to shift relative to each other, and enable the active channel 43 of the active adjust element 40A to be aligned with the dead latch of the mechanical lock box, and then one may tighten the adjust screw 22 to return the active adjust element 40A and the fixed adjustment element 30A to an occlusion state, so the procedure for adjusting the position of the active channel 43 is completed. Therefore, since the occlusal state of the active adjust element 40A and the fixed adjustment element 30A is formed by tightening the adjust screw 22, the active channel 43 located in the active adjust element 40A will not have the problem of offset, and the active adjust element 40A and the fixed adjustment element 30A are arranged at the outer side of the electronic lock body 10, so the position of the active channel 43 can be directly adjusted by loosening the adjust screw 22 from the plate 20, therefore, the present invention does not require one to disassemble the entire electronic lock from the door frame, and one can directly adjust the position of the dead latch channel from the electronic lock plate under the condition that the main structure of the electronic lock is not removed at all, to avoid the malfunction of the electronic lock.

(15) Moreover, referring to FIGS. 10A and 10B, a second embodiment of the present invention has a fixed adjust element 30B and an active adjust element 40B in a second form. A pair of second screw holes 34 are each provided on the fixed adjust element 30B at a position to align with a corresponding second positioning hole 24 (not depicted in FIGS. 10A and 10B), namely, on each of a a pair of fixing blocks 33 which form the fixed adjust element 30B. Each fixing block 33 engages the bottom surface of the plate 20 by an adjusting screw 22. Each of the fixing blocks 33 has a sliding slot 331, and a sliding active adjust element 40B has a sliding member 44 at each end to fit to a corresponding sliding slot 331. The top surface of each end of the active adjust element 40B is higher than the top surface of the fixing blocks 33, the active adjust element 40B may be arranged between a bottom (or body-facing) surface of the plate 20 and the fixing blocks 33, the middle section of the active adjust element 40B has a ramp element 42B corresponding relative to the latch bolt 12, the ramp element 42B having an active channel 43, and the width of the active channel 43 is narrower than the distance between the pair of the fixing blocks 33.

(16) Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
