DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] Referring to FIGS. 1-6, a first embodiment of the present invention, including: an electronic lock body 10, having a housing cavity 11 and a latch bolt 12; a plate 20, using plate screws 13 to combine to 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 fixed adjust element 30A, two ends of the fixed adjust element 30 are using adjust screw 22 to combined to the bottom surface of the plate 20, the middle section of the fixed adjust element 30 is arranged at a rod 31 which arranged below the gap 21, and set a fixed channel 32; and an active adjust element 40A, having a sleeve slot 41 relative to the rod 31, and having a ramp element 42 corresponds to the latch bolt 12, the active adjust element 40A sleeved to between the bottom surface of the plate 20 and the rod 31; the ramp element 42A having an active channel 43 relative to the positioning channel 32, the width of the active channel 43 is narrower than the width of the fixed channel 32.
[0024] With the feature disclosed above, referring to the FIGS. 7-9, 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 loosen the adjusting screw 22 (the adjusting screw 22 is not removed) to let the active adjust element 40A and the relative fixed adjust element 30A shifted, let the active channel 43 of the active adjust element 40A be aligned with the dead latch of the mechanical lock box, and then tighten the adjust screw 22 to make the active adjust element 40A and the fixed adjustment element 30A return to 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 formed by tighten 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 need to disassemble the entire electronic lock from the door frame, and 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.
[0025] 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 second type, the fixed adjust element 30B are combined to a pair of the fixing blocks 33 the bottom surface of the plate 20 by an adjusting screw 22, the fixing blocks 33 has a sliding slot 331; the sliding element 40B has a sliding member 44 at the two ends set to the sliding slot 331, making the top surface of two ends of the active adjust element 40B higher than the top surface of the fixing blocks 33, let the active adjust element 40B be arranged between a bottom surface of the plate 20 and the fixing blocks 33, the middle section of the active adjust element 40B set a ramp element 42B 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.
[0026] 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.
