Description

Vane lock and private key thereof

Technical field

The utility model belongs to lock technology field, relates to a kind of blade lock, particularly a kind of vane lock and private key thereof.

Background technology

Existing blade lock comprises lock housing, lock core, vane group and key, wherein vane group consists of blade and leaf spring, vane group is arranged in the vane hole of lock core, at lock-shell lining, be opened in the lock hole that blade tip matches, when sealed, blade, by lock core and lock housing locking between the vane hole of lock core and the lock of lock housing hole, can not rotate with respect to lock housing lock core; While unblanking, after key is inserted to keyhole, wave tartar is on the key stirred corresponding blade and is moved, the locking of releasing to lock core, thereby lock core can be rotated with respect to lock housing, by the shifting block on lock core, the lockset being attached thereto is opened, reach the object of unblanking.

But this class blade lock has been developed out the existing longer time, lawless person has worked out the mode of unblanking accordingly gradually, and MASTERKRY is exactly wherein the most frequently used a kind of.MASTERKRY is the general name that instrument is stirred in combination that many steel wires, cleek and tooth are molded as in fact, its principle of unblanking is exactly with numerous instruments of stirring such as steel wire, iron plate, tooth moulds, utilize some very common Mechanics of Machinery principles, use skilful power to stir blade, make interior outer leafs bob produce instantaneous gap, coordinate rotational lock core proper opportunity, just can at one stroke lock be opened, for some veterans, most blade lock can be opened easily, the size of key of lockset is not enough, and theftproof performance is poor.

Summary of the invention

The purpose of this utility model is studied thorough for existing common blade lock, the problem that theftproof declines, and proposed a kind ofly at the inner safety structure of hiding of lockset, need be equipped with vane lock and private key thereof that private key just can be opened.

The purpose of this utility model can realize by following technical proposal: a kind of vane lock and private key thereof, described blade lock comprises lock housing, lock core and vane group, lock core is arranged in lock housing and can rotates with respect to lock housing, vane group is arranged between lock housing and lock core, it is characterized in that, between described lock core and lock housing, be also provided with safety structure, this safety structure comprises the outer marble hole being opened on lock-shell lining and is opened in the interior marble hole of lock core sidewall, one of described interior marble hole is communicated with the keyhole of lock core, other end can be communicated with outer marble hole, in interior marble hole, be provided with the insurance pellet that can move back and forth between interior marble hole and outer marble hole, in outer marble hole, be provided with resetting-mechanism, above-mentioned insurance pellet has and moves in interior marble hole so that lock core and lock housing movement tendency in relative rotation under the driving of resetting-mechanism, described private key comprises key body, on key body, offer snakelike tartar and pellet position, the inner of insurance pellet is arranged in pellet position so that insurance pellet outer end and can receives completely to interior marble hole.

After key body is inserted in keyhole, its snakelike tartar and vane group corresponding matching, so that vane group is removed the locking to lock core.Meanwhile, present position, pellet position can with interior marble hole over against, simultaneously for insurance pellet return space is provided, allow insurance pellet can be retracted to completely in interior marble hole, between lock core and lock housing, can relatively rotate, complete and unblank.

In above-mentioned vane lock and private key thereof, described resetting-mechanism comprises return pellet and spring.Spring drives return pellet that insurance pellet is pressed in interior marble hole under equilibrium state, makes return pellet just rest on the junction of lock core and lock housing simultaneously, does not hinder lock core to rotate with respect to lock housing.

In above-mentioned vane lock and private key thereof, of coordinating with pellet position of described insurance pellet is round end shape, and pellet position shape matches with it.

In above-mentioned vane lock and private key thereof, the side of described lock housing offers draw-in groove, is fixed with stiffener in draw-in groove.

In above-mentioned vane lock and private key thereof, the steady pin by riveted joint between described stiffener and lock housing is fixed together.

Compared with prior art, this vane lock and private key thereof have increased by one group of safety structure, together with vane group, play the effect of double anti-theft, and size of key is large, and theftproof performance is strong.

The specific embodiment

Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

As shown in Figure 1, this vane lock comprises lock housing 1, lock core 2 and vane group, and lock core 2 is arranged in lock housing 1 and can rotates with respect to lock housing 1, and vane group is arranged between lock housing 1 and lock core 2, between lock core 2 and lock housing 1, is provided with safety structure.

As shown in Figure 2, the private key corresponding with above-mentioned blade lock comprises key body 3, offers snakelike tartar 31 and pellet position 32 on key body 3.

As shown in Figure 3, safety structure comprises the outer marble hole 11 being opened on lock housing 1 inwall and the interior marble hole 21 that is opened in lock core 2 sidewalls, one of interior marble hole 21 is communicated with the keyhole 23 of lock core 2, other end can be communicated with outer marble hole 11, in interior marble hole 21, be provided with the insurance pellet 22 that can move back and forth between interior marble hole 21 and outer marble hole 11, one of coordinating with pellet position 32 of insurance pellet 22 is round end shape, pellet position 32 shapes match with it, are provided with return pellet 12 and spring 13 in outer marble hole 11.

While not inserting key, insurance pellet 22 is positioned at

marble hole

21,12 of return pellets are stayed in outer marble hole 11, the inner of insurance pellet 22 extends in keyhole 23 always, and push up to the inwall of keyhole 23 under the effect of spring 13, outer end is separated with the intersection of lock housing 1 at lock core 2 with return pellet 12, and outer marble hole 11 and interior marble hole 21 are just over against (as shown in Figure 3).

Private key inserts in keyhole 23 processes, key body 3 promotes outside marble hole 11 motions of insurance pellet 22, the inner of insurance pellet 22 promotes return pellet 12 and is inserted in outer marble hole 11, in this process, spring 13 is compressed, the main body of insurance pellet 22 is stuck in the intersection of lock core 2 and lock housing 1, and now lock core 2, by circumferentially (being the direction of key turns) locking, cannot rotate (as shown in Figure 4) with respect to lock housing 1.

After key body 3 propelling movements put in place, the tartar 31 on key body 3 coordinates with vane group, and vane group action, removes the locking to lock core 2.Simultaneously, pellet position 32 on key body 3 just with interior marble hole 21 over against, spring 13 resets, promote the 32 direction motions to pellet position of return pellet 12 and insurance pellet 22, the inner of insuring pellet 22 is inserted in pellet position 32, insurance pellet 22 and return pellet 12 are reset to state while not inserting key (as shown in Figure 3), and now lock core 2 can rotate with respect to lock housing 1, and rotation key gets final product so that lock core 2 rotates and unblanks.

When if the key inserting is non-matching key, on it position of non-marble position 32 or pellet position 32 can not with 22 pairs of pellets of insurance on, do not provide the return space that insurance pellet 22 resets under spring 13 effects, insuring pellet 22 can be stuck between lock core 2 and lock housing 1, play the effect of locking lock core 2, in conjunction with vane group, play the effect of double anti-theft.

In order to strengthen lock housing 1 with respect to the intensity of lock core 2 opposite sides, can offer draw-in groove 4 at the side of this side, in draw-in groove 4, be fixed with stiffener 5, the steady pin 6 by riveted joint between stiffener 5 and lock housing 1 is fixed together.
