Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.

As shown in the figure, a kind of can self-locking electronic lock, comprise lock housing 1, lock core assembly and plectrum 2, lock core assembly comprises electric drive part and mechanical driving part, mechanical driving part comprises lock core mount pad 3, lock core cover 4, drive block 5, pushing block 6 and limited post 7, drive block 5 horizontal slips are plugged in lock core mount pad 3, on drive block 5, be connected with resetting block 51, between resetting block 51 and lock core mount pad 3, apical grafting has the first back-moving spring 52, on the first back-moving spring 52, be coated with minor flaps 53, minor flaps 53 is crimped on lock core mount pad 3, the vertical sliding plug of pushing block 6 is in lock core mount pad 3 and be positioned at the place ahead of drive block 5, electric drive is partly arranged in lock core mount pad 3, electric drive partly comprises motor 8, on lock core cover 4, be embedded with motor limit base 41, motor 8 is arranged on motor limit base 41, on the driving shaft of motor 8, be fixedly installed square rotating shaft 81, the bottom of pushing block 6 is provided with post-receiving chamber 61, rotating shaft 81 plugs through post-receiving chamber 61 and limited post 7, one side lower end of post-receiving chamber 61 has been wholely set block 62, between pushing block 6 and lock core cover 4, apical grafting has the 3rd back-moving spring 63, the front portion of lock core mount pad 3 is provided with vertical ladder hole 31, in ladder hole 31, be provided with position blocking pin 9, between position blocking pin 9 and ladder hole 31, apical grafting has the second back-moving spring 32, limited post 7 is positioned at the below of position blocking pin 9, on limited post 7, be provided with the spacing hole 71 for matching with the lower end of position blocking pin 9 radially, the front end of limited post 7 is wholely set the locating piece 72 of oriented front protrusion, on lock core mount pad 3, be provided with positioning step 34, locating piece 72 be positioned at positioning step 34 under, the upper end of position blocking pin 9 is arc tips, in lock housing 1, be provided with the deep-slotted chip breaker 11 that the arc tips with position blocking pin 9 matches, on lock core mount pad 3, be embedded with positioning ball 33, positioning ball 33 is positioned at the inserted terminal of drive block 5 and lock core mount pad 3, and positioning ball 33 is positioned at the top of drive block 5, in lock housing 1, be provided with the locating slot 12 matching with positioning ball 33, locating slot 12 is positioned on same axial straight line with deep-slotted chip breaker 11, plectrum 2 is socketed in the leading section of lock core mount pad 3.

The course of work of this electronic lock is as follows:

While unblanking, in key insertion lock core mount pad 3, promoting drive block 5 moves forward, positioning ball in lock core mount pad 3 33 embeds in the steel ball hole of key simultaneously, because drive block 5 moves forward, now the first back-moving spring 52 is compressed, drive block 5 promotes pushing block 6 and moves down (as shown in Figure 2), the 3rd back-moving spring 63 is compressed, now motor 8 drives rotating shaft 81 to clockwise rotate (as shown in Figure 3), rotating shaft 81 drives limited post 7 to clockwise rotate simultaneously, after rotating 90 °, the locating piece 72 of limited post 7 front ends is blocked by the positioning step 34 on lock core mount pad 3, motor 8 stops operating, now the spacing hole on limited post 7 71 is aimed at the lower end (as shown in Figure 5) of position blocking pin 9, then rotate key, positioning ball 33 departs from the locating slot 12 of lock housing 1 under the drive of key, position blocking pin 9 moves under the drive of key in spacing hole 71 simultaneously, the arc tips of position blocking pin 9 departs from the deep-slotted chip breaker 11 of lock housing 1, the second back-moving spring 32 is compressed, now key turns band movable lock core mount pad 3 rotates, lock core mount pad 3 rotates and drives plectrum 2 to rotate simultaneously, lock is opened (as shown in Figure 6).

While locking, rotating key band movable lock core mount pad 3 rotates, because positioning ball 33 embeds in the steel ball hole of key, therefore, only when positioning ball 33 is aimed at the locating slot 12 of lock housing 1, key just can be extracted, simultaneously, the arc tips of position blocking pin 9 is also aimed at the deep-slotted chip breaker 11 of lock housing 1, position blocking pin 9 moves up under the promotion of the second back-moving spring 32, the arc tips of position blocking pin 9 coordinates (as shown in Figure 5) with deep-slotted chip breaker 11, and now, drive block 5 moves backward under the promotion of the first back-moving spring 52, positioning ball 33 coordinates with locating slot 12, pushing block 6 under the promotion of the 3rd back-moving spring 63, move up and pushing block 6 on block 62 drive when moving up rotating shaft 81 to rotate counterclockwise (i.e. the state from the replying state of Fig. 3 to Fig. 2), rotating shaft 81 drives limited post 7 to rotate counterclockwise simultaneously, now the spacing hole 71 on limited post 7 departs from the lower end (as shown in Figure 4) of position blocking pin 9, make position blocking pin 9 block lock housing 1, realize locking function.
