The specific embodiment
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 antitheft blade lock, comprise lock housing, be built in lock core 2 in the lock housing 1 and supporting external-open clavis spoon 3, the one side both sides of described external-open clavis spoon 3 have outer mill teeth groove 4, and the sidewall of outer mill teeth groove 4 is provided with tartar 5; Described lock core 2 upper edge axially parallels are provided with a plurality of blade grooves 6 that radially run through lock core, blade groove 6 communicates with the keyhole 10 that axially arranges, the end of lock core keyhole 10 is provided with the roof pressure face 11 that cooperates with key 3 heads, it is a pair of right towards opposite blade to be provided with in the described blade groove, i.e. first blade 7 and second blade 8.Increasing blade quantity can increase the reliability of lockset, improves anti-theft security.All have the square tartar hole 13 at middle part on each blade 7,8 and is connected the spring location retaining 14 of leaf spring 12 usefulness, described spring location keeps off and is arranged on blade 7,8 outer rim.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 first blade 7, second blade 8 in tartar hole 13 the outer mill teeth groove position corresponding to key be the corner in tartar hole, have the first step 7.1 and the second step 8.1 that extend towards tartar hole, center direction respectively, the tartar 5 on first step 7.1 and second step 8.1 and the key correspondence position is complementary.
Every blade of present embodiment all disposes a leaf spring 12, and an end of leaf spring 12 acts on the spring location retaining 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 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.One spring leaf 20 is also fixedly arranged on the described lock body 1, and 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 to limit the axis shift of 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, first blade 7 and 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 cooperate 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 12, first step and second step are close to the tartar face of the outer mill teeth groove of key respectively, and along with key 3 inwardly advances, blade is radially mobile in blade groove 6.When key 3 inserts fully, on the roof pressure face 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 to promote key 3 this moment, because the effect of roof pressure face 11, key 3 is being with lock core 2 relative lock housings 1 to move axially, the locked groove 19 that the 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 the tartar of the outer mill teeth groove of key and the step of blade do not match, blade can't withdraw from the hole slot 9 of both sides 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 avoided twisting off the key phenomenon, and it is simple in structure, security performance good, and fault rate is low.
