Description
Technical field
It the utility model is related to the tapered end part of spring lock, particularly a kind of theftproof lock lock with marble hole in stairstepping
Head.
Background technology
The structure of existing cylinder lock part as seen in figs. 8-10, including lock core 4, lock core sleeve 5 and billiard mechanism；Lock
Core retainer plate 5 is provided with axially extending lock core hole and the outer marble hole radially extended, and lock core hole is penetrated to another from one end of lock core sleeve 5
One end, axial directional distribution of the outer marble hole along lock core sleeve 5 have multiple, and it is penetrated into lock core hole from the outer surface of lock core sleeve 5.
Lock core 4 is provided with axially extending keyhole 41, the left inside mounting hole radially extended, right interior installing hole, the radial direction radially extended
The interior marble hole of extension.One end of keyhole 41 from lock core 4 is penetrated to the other end, and left inside mounting hole and right interior installing hole are symmetrically set
Put and penetrated in the both sides of keyhole 41, both of which from the outer surface of lock core 4 into keyhole 41, interior marble hole is upper from lock core 4
End surfaces are penetrated into keyhole 41.Lock core 4 is movably arranged in the lock core hole of lock core sleeve 5, and its interior marble hole can be with lock core sleeve 5
Outer marble hole be connected.Billiard mechanism include left inside plug 60, left inside spring 61, left inside pellet 62, the right side in plug 63, the right side in
Pellet 65, interior locking pellet 66, outer locking pellet 67, outer spring 68 and outer plug 69 in spring 64, the right side；Left inside pellet 62, a left side

Left inside mounting hole in, pellet in the right side, plug is sequentially arranged in the right interior installing hole of lock core in right inner spring and the right side, interior locking
Pellet is arranged in the interior marble hole of lock core, and outer locking pellet, outer spring and outer plug are sequentially arranged at the outer pellet of lock core sleeve
Kong Zhong；
In the lockout condition, pellet is made a concerted effort locking pellet in pushing tow in left inside pellet and the right side, so that interior locking pellet and outer
The wall surface of the hole of the contact surface and lock core hole that lock pellet staggers, and then lock core can not rotate in lock core hole；
Under unlocking condition, pellet is extruded and pacified in retract respectively left inside mounting hole and the right side by key in left inside pellet and the right side
Fill in hole, interior locking pellet is jacked or fallen with the tartar of key, so that the contact of interior locking pellet and outer locking pellet
Face is concordant with the wall surface of the hole of lock core hole, and then lock core can be driven by key and be rotated in lock core hole；
N number of interior marble hole is shared on lock core, wherein, it is shoulder hole to have marble hole in X, and Y interior marble holes are straight hole；X+
Y=N, X >=1, N >=3；Shoulder hole be big footpath section close to one section of lock core outer surface, and shoulder hole is in one section of close keyhole
Path section；Bilateral gap between the big footpath section of the shoulder hole and corresponding outer locking pellet is A, the straight hole with it is relative
Bilateral gap between the outer locking pellet answered is B, A ＞ B.
The further technical scheme of the utility model is：Lock core sleeve is arranged in the most long interior locking pellet of differential middle length
The outer marble hole of axial direction front end is into any straight hole between the outer marble hole of lock core sleeve axial direction rearmost end.
Further technical scheme is the utility model：The aperture of the big footpath section of shoulder hole and corresponding outer pellet
Hole aperture is consistent；The aperture of the straight hole is consistent with corresponding outer marble hole aperture.
The further technical scheme of the utility model is：The aperture for defining the big footpath section of shoulder hole is W, then A value
Scope is 0.08W-0.5W.The aperture for defining straight hole is Z, then B span is 0.04Z-0.07Z.
The further technical scheme of the utility model is：Left inside mounting hole and right interior installing hole are shoulder hole；Accordingly
, pellet is in multi-diameter shaft shape in left inside pellet and the right side, and left inside pellet is pressed in left inside under the elastic force effect of left inside spring

On.
The utility model has the following advantages that compared with prior art：
1st, theftproof performance is better than existing spring lock.Gap between each hole of existing spring lock and pellet be it is consistent,
Inserted using lock tool is stolen in keyhole, it is only necessary to which being adjusted to correct position just can once open, and be easier to steal and lock successfully.This
The bilateral gap of interior marble hole and outer locking pellet in utility model is not consistent, point for having size, when entering pirate lock,
Need first opening clearance it is small that is several, then adjust opening clearance it is big that is several, add robber's lock difficulty, improve anti-theft
Energy.
2nd, it is shoulder hole to have marble hole in X, and the path section of shoulder hole is accurately oriented to for the mobile offer of interior locking pellet,
Locking pellet outside the big footpath Duan Keyu of shoulder hole is set to form larger gap.
3rd, it is arranged on the outer marble hole of lock core sleeve axial direction front end extremely in the most long interior locking pellet of differential middle length
In any straight hole between the outer marble hole of lock core sleeve axial direction rearmost end.Under unlocking condition, differential middle length is most long
Interior locking pellet and the wall surface of the hole of lock core hole maintain an equal level, and need to stretch into two panels sheet when stealing lock and steal lock tool and enter keyhole, steal and lock
Piece A is used to push down left and right interior pellet, steals locking plate B and is used to stir each interior height for locking pellet, it is necessary to which each interior locking pellet is dialled
Moving the position of unlocking can unlock, but is limited by the most long interior locking pellet of differential middle length and (steal locking plate B and stretch into keyhole
Afterwards, lower end directly contacts with stealing locking plate A, and stealing locking plate A can not arbitrarily move, now, the most long interior locking bullet of differential length
The upper end of son flushes with the wall surface of the hole of lock core hole substantially, and robber's locking plate B scope of activities is minimum, and micro twisting can all cause level
The most long interior locking pellet of poor length is extend into outer marble hole, cause steal lock failure) and key hole width limitation, robber locking plate
B scope of activities is very small, it is difficult to which the position for being adjusted to unlock by each interior locking pellet, robber's lock difficulty is very big, improves antitheft
Performance.
