Description

Robber opens suicide and prohibits robber's lock

Technical field

The utility model belongs to a kind of mechanical anti-theft lock.

Background technique

Common mechanical cylinder lock, lock core front end are key inlet port, and key groove hole is set in lock core, and slot side is equipped with bullet Sub-aperture, lock core are located in lock core sleeve, and lock core sleeve corresponds to lock core marble hole and also is provided with marble hole, and one is equipped in the marble hole in lock core Layer pellet, corresponding one layer of pellet is equipped with two layers of pellet in lock core sleeving marble hole, and two layers of pellet rear end are equipped with spring and press one or two layers Pellet, spring rear end are enclosed on lock body, and lock core rear end is equipped with opening pin, open lock to stir lock tongue.Usually spring top One or two layers of pellet downlink are held, two layers of pellet latching are not able to rotate lock core between lock core and lock core sleeve.

When unlatching, key is inserted into lock core key slot, between tooth on the key makes between one layer of pellet and two layers of pellet When gap is placed exactly in the adjacent interfaces of lock core and lock core sleeve, lock core gets rid of lock core sleeve (two layers of pellet) constraint；Next rotation key Spoon band movable lock core rotates, and by common sense, has rotated lock core and also means that and open lock.In conclusion unlocking condition has and is at two: one Cooperation, two be (drive) external force, and Neither of the two can be dispensed.Technical unlocking is with key unlocking program on the contrary, first exposed It is opened on the lock core of tapered end along it and applies a drive external force on direction of rotation, then enter lock core with pock-poking tools such as sled again Key slot stirs pellet one by one and finds " cooperation ", and " cooperation " drives external force to work at any time once completing, and band movable lock core rotates Open lock.This opening ways are lossless to component inside and outside lockset and performance the slightest, and clean stand falls, and leave no trace, are advanced robber persons Usual gimmick.

To prevent or avoiding lockset is stolen to open, people painstakingly, have produced miscellaneous theftproof lock, omnifarious Anti-theft technique emerges one after another.Only change pellet shape at most or increase pellet number, only by increasing group sled difficulty and prolonging It is long to dial the sled time to improve anti-theft performance.It fails to really restrain technical unlocking.

Summary of the invention

The purpose of this utility model is to design a kind of steal to open suicide taboo robber's lock.Keeping above-mentioned common spring lock basic structure On the basis of, in lock core sleeve inner wall, add one group of suicide marble hole on the necessary route of one layer pellet when lock core acts, in fill out T-shape suicide pellet, inclined power tower spring and major part pin-lift arrangement, suicide pellet outer end of hole are the retaining mounting of center opening, major part Mandril tail end passes through inclined power tower spring and hides in retaining mounting hole, and outer end face keeps flushing with retaining mounting outer surface.The device The lock core for only allowing to have key therefrom to cooperate is committed suiside pellet group to weather, otherwise, is in inclined power tower spring and major part mandril always Suicide pellet group under high pressure can squeeze by force one layer of pellet and enter lock core marble hole before the movement of lock core Effect of Rotation lock tongue, Implement suicide coak in lock core and lock core inner room.Pellet design of committing suiside is upper only into not moving back, which can not also solve It removes.Lockset does not stint suicide (locked scrap) and exchanges owner's lives and properties for and be inviolable, and the anti-theft performance of lockset is performed to the limit. Technical unlocking can fundamentally be restrained.

The utility model has the advantages that on the basis of keeping existing pellet Lock structure completely constant, in lock core sleeve inner wall, Lock core act when one layer pellet necessary route on add one group of special-shaped marble hole, in fill out T-shape suicide pellet, inclined power tower spring With major part pin-lift arrangement, pellet outer end of hole of committing suiside is the retaining mounting of center opening, and major part mandril tail end passes through inclined power tower spring and buries In retaining mounting hole, outer end face keeps flushing volt with retaining mounting outer surface.With relatively simple design and lower production Cost realizes effectively antitheft.The lock body of the utility model, which is opened, must use key, because only that the lock that key therefrom cooperates Core can just make the gap of one or two layers of pellet just in the adjacent interfaces of lock core and lock core sleeve, i.e. all marble holes of lock core are located In filling up state by one layer of pellet.The pellet group at this point, lock core could commit suiside to weather；But if being sought again by stirring pellet one by one It looks for " cooperation ", and the last one pellet " cooperation " drives external force to work at any time once completing, band movable lock core rotates, lock core marble Due to not having key, therefrom branch support is held, and the suicide pellet under inclined power tower spring and major part mandril high pressure can rotate shadow in lock core Before ringing lock tongue movement, one layer of pellet is squeezed by force and enters lock core marble hole, implement suicide coak in lock core and lock core inner room.It is flat When, major part mandril tail end is contained in retaining mounting hole, and mandril tail end end face keeps flushing with mounting outer surface, and inclined power tower spring pushes Major part mandril and suicide pellet downlink, mandril tail end certainly will be detached from retaining mounting hole；Inclined power tower spring and mandril big end surface spherical surface Or cone match design, it is to play mandril to greatest extent and tilting the amount of swinging.Major part mandril once deviates from retaining mounting hole, That fearness of tail end has slight wallowing motion, and also retaining mounting hole is retracted on the road Bie Xiangzaiyuan to mandril tail end.Always suicide pellet is held on top It can not playback, suicide pellet design is upper only into not moving back, which can not also release.Lockset is with the sacrifice (lock of itself Undeliverable telegram is useless) it exchanges owner's lives and properties for and is inviolable, the anti-theft performance of lockset is performed into the limit.Any robber person is set cannot It is no longer attempt to steal and opens the lock.

Specific embodiment

A kind of steal opens suicide taboo robber's lock, as shown in Figures 1 to 6.By lock core 1, key slot 2, lock core sleeve 3, lock core marble Hole 4, lock core sleeving marble hole 5, one layer of pellet 6 of lock core, two layers of pellet 7 of lock core sleeve composition common spring lock on the basis of, in lock core Cover inner wall, lock core act when one layer pellet necessary route on add one group of suicide marble hole 8, in fill out T-shape suicide pellet 9, inclined power tower spring 10 and 11 device of major part mandril, suicide pellet outer end of hole are the retaining mounting 12 of center opening, major part mandril 11 Tail end passes through inclined power tower spring 10 and hides in retaining mounting hole 13, and outer end face keeps flushing with retaining mounting outer surface.Lock core is set In lock core sleeve, key slot 2 is located at lock core front end.As shown in Figure 5.The lock core that the setting only allows to have key 14 therefrom to cooperate Commit suiside to weather pellet group, otherwise as shown in fig. 6, always under inclined power tower spring 10 and 11 high pressure of major part mandril from guided missile Son can squeeze by force one layer of pellet 6 and enter lock core marble hole 4, in lock core and lock core sleeve before the movement of lock core Effect of Rotation lock tongue Between implement suicide coak.Pellet design of committing suiside is upper only into not moving back, which can not also release.

As shown in Figures 2 and 3, the major part mandril, big end surface are designed as spherical surface or the conical surface, make its big end surface It is limited to point contact, major part mandril downlink with suicide pellet, tail end provides once being detached from retaining mounting hole to realize that mandril tilts It is convenient to the greatest extent.

As shown in figure 4, the inclined power tower spring, diameter is up big and down small, the end coil quilt with major part ejector pin contact A tilt angle is pulled out, bearing force is biased to release.It must run-off the straight when ensuring that major part mandril deviates from retaining mounting hole.Its Diameter design be it is up big and down small, also the major part mandril to be contained in abdomen provides the universal inclined spaces of amplitude peak.Described is big Crown bar, spherical surface (or conical surface) design of big end surface, it is ensured that it must be point contact between suicide pellet.Mandril is worn Inclined power tower spring is crossed, tail end is then contained in retaining mounting centre bore.Inclined power tower spring unites the spherical surface (or conical surface) of mandril major part one end Design makes major part mandril tail end once deviating from retaining mounting hole, and run-off the straight will be a kind of certainty.

As shown in figure 5, the lock body is normally-open, it is necessary to be that the lock core for having key 13 therefrom to cooperate can to weather certainly Guided missile subgroup, because of phase of the gap of one layer of pellet 6 of lock core and two layers of pellet 7 of lock core sleeve just at lock core and lock core sleeve at this time On vicinal, i.e., all marble holes 4 of lock core, which are in, fills up state by one layer of pellet 6.Suicide pellet group can not contend with key tooth The top of one layer of pellet is held, suicide is locked to be implemented.Major part mandril passes through inclined power tower spring, and tail end is contained in retaining mounting hole always In, mandril outer end face is remained with retaining mounting outer surface and is flushed.The abnormity suicide marble hole is up big and down small T Type, lower part aperture is necessarily less than the diameter of one layer of pellet of lock core, and enforcement key, which accidentally pulls out, when preventing lock core from passing through, on one layer of pellet makes At locked.

When lockset once meets with unnormal unlocking, i.e. technical unlocking.Direction, which is rotarily opened, along lock core first applies one External force, and then stir pellet one by one and find " cooperation ", " cooperation " drives external force to work at any time once completing, band movable lock core Rotarily open lock.As shown in fig. 6, lock core marble due to not having key, therefrom hold by branch support at this time, major part is held on the inclined top of power tower spring 10 Mandril 11 and suicide 9 downlink of pellet squeeze one layer of pellet 6 by force and enter lock core marble before the movement of lock core Effect of Rotation lock tongue Suicide coak is implemented in lock core and lock core inner room in hole 4.Since major part mandril under the effect of Pian Lita spring hold under suicide pellet by top Row, is bound to cause mandril tail end and deviates from from retaining mounting hole, form the universal inclination of mandril as shown in Figure 4.This moment, by dialling Sled tool, which enters plug keyway, to be stirred and lifts one layer of pellet 6 of lock core, is lifted suicide pellet 9 indirectly, is overcome inclined power tower spring 10 Elastic force pushes 11 uplink of major part mandril, and the mandril tail end after inclination can resist retaining mounting 12 always, anyway all without decree Its backtracking retaining mounting hole, once that is, suicide pellet downlink just can not playback.The suicide coak refers to certainly Guided missile, can only be into cannot move back under the cooperation of Pian Lita spring, major part mandril and retaining mounting.

The suicide pellet is up big and down small T stage scalariform.Moment hides in lock core sleeving marble hole, and behind partially The top of power tower spring and major part mandril is held under effect, and the moment is in first-degree combat readiness state.Major part mandril tail end is contained in retaining mounting hole In, mandril tail end end face keeps flushing with mounting outer surface, and the length that the thickness of retaining mounting is less than one layer of pellet of lock core is differential. To ensure as shown in fig. 6, even if major part mandril remains to downlink abjection retaining envelope when one layer of pellet of lock core is designed as full-size Piece；Inclined power tower spring unites the spherical surface or conical surface design of mandril stub end, plays mandril inclination to greatest extent.Major part mandril is once Deviate from retaining mounting hole, that fearness of tail end has slight wallowing motion, and mandril tail end is not also thought to retract retaining mounting hole again, thus Enable the suicide pellet for starting suicide function that can not retreat playback.The suicide function can not release.

In short, the utility model is suitable for various spring locks, it is that the optimal performance of high grade anti-theft lock promises to undertake baseline.With more Simple design and lower cost of manufacture realize antitheft upgrading.The anti-theft performance of spring lock can be performed to the limit.And from Fundamentally restrain technical unlocking.Making any robber person can't rethink as opening the lock with trial robber.
