The specific embodiment

Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, the utility model is namely opened a kind of embodiment of Anti-theft vane lock, comprise lock housing 1, be built in the lock housing 1 lock core 2 and supporting in open clavis spoon 3, open the center of one side of clavis spoon 3 in described with along mill teeth groove 4 in the key direction, and be provided with tartar 5 in the interior mill teeth groove 4; Be arranged with vertically a plurality of blade grooves 6 that radially run through lock core on the described lock core 2 in parallel, blade groove 6 communicates with the keyhole 10 that axially arranges, the end of lock core 2 keyholes 10 is provided with the top pressure surface 11 that cooperates with key 3 heads, be provided with in the described blade groove a pair of on the contrary towards blade pair, i.e. the first blade 7 and the second blade 8.Increasing blade quantity can increase the reliability of lockset, improves anti-theft security.All with the tartar hole 13 at middle part be connected the spring location gear 14 of leaf spring 12 usefulness, described spring location gear is arranged on blade 7,8 outer rim on each blade 7,8.Blade groove 6 corresponding to lock core 2 on described lock housing 1 is provided with hole slot 9, blade 7, a side of 8 stretch in the hole slot 9 on the lock housing 1, and on the first blade 7, the second blade 8 in tartar hole 13 corresponding to the interior mill teeth groove position of key respectively with the first projection 7.1 and second projection 8.1 of extending towards tartar hole, center direction.Tartar 5 on the first projection the 7.1 and second projection 8.1 and the key correspondence position is complementary.

The every blade of the present embodiment all disposes a leaf spring 12, and an end of leaf spring 12 acts on the spring location gear 14 of blade, and the other end acts on the lock core 2; Also can adopt a blade to sharing the mode of a leaf spring 12.

The end of the lock core 2 of the present embodiment is provided with dead bolt 15, and dead bolt 15 is provided with the cooperation hook 16 that cooperates with locked groove 19 on the lock body action piece tapered end.Also be fixed with a spring leaf 20 on the described lock body 1, described spring leaf 20 1 ends are fixed on the lock body 1, and other end active action is on latch hook 19 ends of lock body action piece.The effect of its spring leaf 20 is: can be automatically when unblanking with lock body action piece bullet from dead bolt 15.Wherein also other counterparts can be set according to the mode of lock body action piece on the dead bolt 15.

Described lock housing 1 is provided with stroke pin 17, is provided with cotter slot 18 corresponding to the stroke pin 17 on the lock housing 1 on described lock core 2, and stroke pin 17 can be done relative telescopic slide in cotter slot 18.The effect of stroke pin is the axis shift of limiting lock core 2, guarantees the motion track of lock core 2, prevents the excessive disengaging lock housing 1 of lock core 2 displacements.

Its operating principle: under the locking states, key is not in keyhole, the first blade 7 and the second blade 8 are under the effect of leaf spring 12, in blade groove 6, stretch out, insert respectively in the hole slot 9 of lock housing 1 both sides, lock housing 1 thereby pinned by blade, the action piece tapered end of lock body is the locking attitude owing to cooperating in hook 16 and the cooperation hook 16 that is locked to cooperating of locked groove 19 on the dead bolt 15.When unblanking, the tartar hole that key 3 passes blade central authorities advances to keyhole, and under the pressure of leaf spring, the first projection and the second projection are close to respectively the two side of mill teeth groove in the key, and along with key inwardly advances, blade is radially mobile in blade groove.When key inserts fully, on the top pressure surface 11 of key 3 head conflict lock cores 2 keyholes 10 ends, if the blade on the tartar 5 in the key in the mill teeth groove 4 and the relevant position is complementary, then blade withdraws from the hole slot 9 of both sides fully, continues this moment to promote key 3, and key 3 moves axially with lock core 2 relative lock housings 1, the locked groove 19 that cooperation hook 16 on the dead bolt 15 breaks away from the tapered end, and under the effect of spring leaf 20, tapered end breaks away from dead bolt 15, realizes unblanking.If key tooth flower and blade do not mate, blade can't withdraw from hole slot 9 fully, and lock core is still locked, can not finish and unblank.The utility model has been realized the telescopic mode of unblanking, and has changed the direction of motion of original lock core, has both made things convenient for the locking of unblanking, and has avoided twisting off the key phenomenon, and it is simple in structure, security performance good, failure rate is low.
