The specific embodiment

Please referring to Fig. 1,2, this electronic lock comprises a control chip 10, one power supplys 20, one CD-ROM drive motors 40, is fixed in the lock core 50 on the electronic lock housing, and a locking bolt 60.

Wherein, have a radio transceiver unit 30 (with reference to figure 3) on the described control chip 10, and a wireless radio frequency antenna 31 that is electrically connected with radio transceiver unit 30;

Described lock core 50 has a perforate 51 of radially extending, and a lockhole 52 that extends vertically, and described control chip 10 has an electric contact 11 in the corresponding position with these lock core 50 lockholes 52;

One end of described CD-ROM drive motor 40 connects a transmission device 41, and this transmission device 41 connects a latch 42, and has an electric connection point (not shown) on this latch 42, and this electric connection point is electrically connected with described control chip 10.

Described locking bolt 60 is divided into two ends, and wherein first end 61 is fixed on the housing of this electronic lock, and is electrically connected with described motor 40 by an electric connection point 12 that has on this first end 61; Second end 62 is inserted in when locking in the lockhole 52 that extends vertically of described lock core 50; Described second end 62 has a storage tank 621, and this storage tank 621 is in latched position in order to ccontaining described latch 42 when this latch 42 is arranged in storage tank 621, is in the unlocked position when breaking away from storage tank 621.When using this electronic lock, described second end 62 is inserted in the described lock core 50, at this moment described storage tank 621 and described perforate 51 aligned in position, described latch 42 insert in the described storage tank 621 by described perforate 51 and are in latched position, and this electronic lock is locked.When this electronic lock was in released state, when promptly described locking bolt 60 did not insert in the lockhole 52 of described lock core 50, described latch 42 was in the unlocked position.
