Abstract
The invention relates to a multi-pin-coupled pin tumbler lock cylinder comprising inner pins, outer pins, springs and door-sealing pins. The inner pins, the outer pins, the springs and the door-sealing pins are connected in sequence in a one-to-one correspondence manner. Each pin is provided with a thin pin head, and each two or three thin pin heads are stacked in a group from top to bottom, and the thin pin heads in one group are in symmetrical structure. In each group, two thin pin heads in one group form a 7 shape, while the middle one of three thin pin heads in another group is in a T shape. The multi-pin-coupled pin tumbler lock cylinder has the advantages that the thin pin heads fit with a key to lock or unlock; the number of combination units of the inner pins, the outer pins, the springs and the door-sealing pins can be increased to allow for better picking resistance while the length of a lock hole is not increased; in addition, the special thin pin heads are easy to bend when a spring lock unlocking method is used, thus force of a spring lock cannot be transmitted to the outer pins.
Description
Technical field
The present invention relates to a kind of lock core, particularly a kind of multi-disc coupling lock cylinder.
Background technology
Cylinder lock generally is made of a plurality of interior pellets, outer pellet, spring and the pellet component units of sealing up a door, it is by a plurality of aforesaid assembled arrangement, the height that pellet in each is set is different, so that the height difference that outer pellet stretches out reaches the locking effect, when key inserts, the profile of tooth that cooperates with lock core by key, lock core is retracted in the pintle hook lock shell so that interior pellet promotes outer pellet, thereby discharges lock core, so that can rotate, the drive dead bolt moves, and reaches the purpose of locking or release.Stir interior pellet by special plectrum exactly in the unconventional mode of unblanking of the prior art, so that all outer pellets are retracted in the lock housing to discharge lock core.Perhaps by bump outer pellet is retracted in the lock housing, the in a flash rotational lock core before the outside pellet resilience is unblanked.
Summary of the invention
The objective of the invention is to provide for the deficiency that solves above-mentioned technology the multi-disc coupling lock cylinder of the unconventional method for unlocking of a kind of effective prevention.
In order to achieve the above object, the multi-disc coupling lock cylinder that the present invention is designed, comprise interior pellet, outer pellet, spring and the pellet of sealing up a door, and interior pellet, outer pellet, spring connects successively with the pellet of being connected, corresponding one by one, described interior pellet is provided with the thin slice marble head, per two above thin slice marble heads are up and down coupling stack setting in groups, and the thin slice marble head that arranges in groups is symmetrical structure, the thin slice marble head is " 7 " font during the even number sheet, thin slice marble head in the middle of during the odd number sheet is " T " font, and all interior pellets are upwards arranged in lock core shaft, form thin slice marble head orientation that assembly closes and be lock core radially, wherein said lock core shaft is to being the direction that key inserts.The characteristics of this structure are to utilize in groups that the thin slice marble head cooperates the effect of playing locking or unblanking with key.Simultaneously can in the situation that do not increase lockhole length, increase the quantity of interior pellet, outer pellet, spring and the pellet assembled unit of sealing up a door, to reach better pick-proof lock effect.Owing to the structure of special thin slice marble head, using the spring lock open method to be in addition, the easy bending of thin slice marble head, and so that the power of spring lock can't be communicated to outer pellet place.
As preferred version, described thin slice marble head in groups, the gap between group and the group is 0.3-0.5mm.This structure is because during the thin slice marble head Group Design of 2-4 sheet, the gradient of its profile of tooth can be less, thereby the self-lock force problem when need not to consider to insert key so that the gap between lock core internal tooth and the tooth can accomplish that the limit is little, is inserted from this gap to prevent plectrum etc.
As preferred version, described interior pellet is staggered, and its axial centre forms broken line.The characteristics of this structure are when using axially as circular list, can in identical length, arrange enter more in pellet.
As preferred version, the side of described thin slice marble head is provided with protrusion, and protrusion can be crossed between the thin slice marble head that guarantees mutually stack has certain gap, closely increases the problem of normal unlocking difficulty to prevent the thin slice marble head owing to fitting.
As preferred version, the axial plane of described interior pellet, outer pellet and the pellet of sealing up a door is for circular or square, to adapt to the needs of various lock.
The resulting multi-disc coupling of the present invention lock cylinder, the thin slice marble head that is superimposed by setting, with in the past only be that the marble head of lockhole axially-aligned is improved to axially and the arrangement of Radial Combinations formula, thereby can in identical space, put into more pellet, outer pellet, spring and the pellet unit of sealing up a door, to improve the safety of lock core.In addition because axially and the Radial Combinations arrangement mode also so that the difficulty that plectrum is unblanked increase.Because the shape of thin slice marble head is special, pellet easily bending under bump on first watch is relatively in the past unblanked thereby prevented to clash into the improper of mode simultaneously.

The specific embodiment
The invention will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
Such as Fig. 1, Fig. 2, shown in Figure 3, the multi-disc coupling lock cylinder that the present embodiment is described, comprise interior pellet 1, outer pellet 2, spring 3 and the pellet 4 of sealing up a door, and interior pellet 1, outer pellet 2, spring 3 and the pellet 4 of being connected connect successively, corresponding one by one, described interior pellet 1 is provided with thin slice marble head 5, per three plate sheet marble heads 5 are up and down coupling stack setting in groups, and the thin slice marble head 5 that arranges in groups is symmetrical structure, the thin slice marble head 5-1 of the left and right sides be " 7 " font as shown in Figure 4, middle thin slice marble head 5-2 is " T " font, as shown in Figure 5.And all interior pellets 1 are upwards arranged in lock core shaft, form thin slice marble head 5 orientations that assembly closes and be lock core radially.The side of described thin slice marble head 5 is provided with protrusion 6, and protrusion 6 can be crossed between the thin slice marble head 5 that guarantees mutually stack has certain gap, and the axial plane of described interior pellet 1, outer pellet 2 and the pellet 4 of sealing up a door is for circular.
