Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the internal construction schematic diagram of the utility model " V " type transformer anti-theft lock;

Fig. 2 is A among Fig. 1-A sectional view;

Fig. 3 is that the B of Fig. 2 is to diagrammatic sketch.

Among the figure: 1. lock body, 2. transformer cover plate, 3. pad, 4. lock core cover, 5. nut, 6. bolt, 7. lock core, 8. dead bolt, 9. lock tongue cavity, 10. lock core hole, 11. lock core grooves, 12. cover plates, 13. lock core trepannings..

The specific embodiment

Fig. 1 shows the internal construction of the utility model " V " type transformer anti-theft lock.Working state figure for " V " type transformer anti-theft lock.In Fig. 1, lock body 1 inside is provided with a cavity, is used to lay lock core cover 4 and cover plate 12, and cover plate 12 is used for the opening portion of capping lock body 1 bottom, and lock core overlaps 4 parts and inserts in the lock core trepanning 13 on the lock body 1, forms the lock body of a sealing.The both sides of lock body 1 are provided with the through hole of two erection bolts.The non-standard bolt 6 that is installed in lock body 1 cavity passes set through hole in lock body 1 top and the through hole on the transformer cover plate 2, matches with the nut 5 that is located at lock body 1 bottom, and pad 3 is between transformer cover plate 2 and lock body 1.The bottom of lock body 1 is provided with the cavity that can hold nut 5, and the top of lock core cover 4 is mutually concordant with the upper surface of lock body 1, and the middle part of lock body 1 is provided with lock core hole 10 and lock core trepanning 13, and lock core 7 is positioned at the lock core hole 10 on lock body 1 and the lock core cover 4.Be located at the dead bolt 8 on the lock core 7, it is stuck on the end face of lock tongue cavity 9.On the end face of the lock core hole 10 of lock body 1, be provided with lock core groove 11.

Fig. 2 shows lock core 7 and lock core cover 4 situations about matching, and shown in the figure is that dead bolt 8 inserts the state that is in pinning in the lock tongue cavity 9.

Fig. 3 has shown lock core groove 11 and has been positioned on the side of lock core, and its width is the width of a screwdriver, and the degree of depth is 2～3 millimeters.

This kind structure for prevent that lock core cover 4 from being taken out in lock body 1, is stuck in the dead bolt on the lock core 78 on the end face of lock tongue cavity 9 of lock core cover 4, and this moment, the front end of lock core 7 stretched in the lock core hole 10 of lock body 1, moved down to prevent lock core cover 4.Because this structure only has dead bolt 8 to be stuck on the end face of dead bolt cavity 9 of lock core cover 4, lock core 7 and lock core hole 10 have certain clearance, so lock core 7 comprises that dead bolt 8 can radially rotation in lock core hole 10.Have only one of employing to be similar to the same instrument of screwdriver, it is stretched in the lock core groove 11, withstand on lock core 7 circumference and exert oneself slightly, and then use the cruciate flower shape key rotation gently that matches with lock core 7, dead bolt 8 is retracted in the lock core 7, thereby by upwards moving in the lock core hole 10, lock core 7 is shifted out outside the shape chamber of lock body 1 lock core 7.Can take out lock core cover 4, unclamp nut 5 with special-purpose interior five side's wrench again, and then successively whole lock is opened.

This transformer anti-stolen lock, when work, earlier with the non-standard nut 5 fastening transformer cover plates 2 of non-standard bolt 6, pad 3 and special use in the through hole of lock body 1, cover on nut 5 with cover plate 12 and lock core cover 4 again, and then with key dead bolt 8 is screwed in the lock cores 7, lock core 7 is put into lock core hole 10, the lower surface of lock core 7 and lock core overlap 4 end face and contact, unclamp key, this moment, dead bolt 8 just sticked within the lock tongue cavity 9.This moment, its transformer anti-stolen lock just can play good burglar-proof result.In the time of need opening, stretch in the lock core groove 11 with the instrument that is similar to screwdriver, withstand on and prevent slightly firmly on lock core 7 circumference that lock core 7 from rotating, with key dead bolt 8 is screwed in to the lock core 7 again, to move on the lock core 7, it is shifted out outside the lock body 1, and just can take out together with lock core cover 4 cover plate 12 this moment from lock body 1 inner chamber, turn on bolt 6 with special-purpose interior five side's wrench then and can open lockset.

Use this anti-stolen lock, simple in structure, easy to operate, burglar-proof result is very good.
