Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, the utility model embodiment provides a kind of anti-stubborn anti-theft lock, comprise cylindric lock core inner core 1, and connected lock core shell 2 vertically, lock core inner core 1 inwardly offers marble hole 11 on two groups by the contact surface with lock core shell 2, on two groups, marble hole 11 is axially arranged in order along lock core inner core 1, pellet 12 is movably installed with in each upper marble hole 11, concrete, upper pellet 12 comprises anti-drilling number pellet, different in nature T word pellet, different in nature step pellet, pick-proof I-shaped pellet and anti-drilling tack pellet.Two groups are provided with tumbler 3 between marble hole 11, and this tumbler 3 can rotate vertically; Lock core shell 2 offers by the contact surface with lock core inner core 1 lower marble hole 21 that two groups run through lock core shell 2, two groups of lower marble holes 21 are axially arranged in order along lock core inner core 1, marble hole 11 on corresponding one of the top of each lower marble hole 21 is also communicated with, bottom is installed with pellet 22 of sealing up a door, and sealing up a door between pellet 22 and upper pellet 12 of correspondence is provided with spring 7; The anti-stubborn intensive aspect 4 (between the two distance can be set to 5mm) corresponding with tumbler 3 is provided with between two groups of lower marble holes 21, these anti-two ends, bottom surface of twisting intensive aspect 4 offer one respectively and run through anti-reinforcement marble hole 41 of twisting intensive aspect 4, the top of each reinforcement marble hole 41 is movably installed with strengthens tack pellet 42, and bottom is installed with sealing pellet 43; The bottom strengthening tack pellet 42 is connected with a top strengthening stop pin 44, and the bottom strengthening stop pin 44 is pressed on the top of sealing pellet 43 by a spring 7.Lock core shell 2 offers two jump-ring slots, 23, two jump-ring slots 23 and be symmetricly set in anti-both sides of twisting intensive aspect 4.
Shown in Fig. 1, Fig. 5 and Fig. 6, often the upper marble hole 11 of group to be divided on first marble hole 11 on marble hole 11 to the 6th from outside to inside successively; Often organizing lower marble hole 21 is divided into the first lower marble hole 21 to the 6th lower marble hole 21 from outside to inside successively.Wherein, between first lower marble hole 21 and the second lower marble hole 21, between the 5th lower marble hole 21 and the 6th lower marble hole 21, on the 5th, marble hole 11 and the 6th is respectively arranged with one group of anti-drill pin 5 between marble hole 11, often organizes anti-drill pin 5 place plane and lower marble hole 21 place plane orthogonal.Preferably, often organize anti-drill pin 5 and comprise two anti-drill pins, 5, two anti-drill pins 5 and arrange about the plane symmetry at place, lower marble hole 21 axle center, and the distance between two anti-drill pins 5 is less than 3.0mm.Lock core inner core 1 and lock core shell 2 offer respectively two anti-anti-grooves 6 of twisting of grooves 6, two of twisting to arrange about place, lower marble hole 21 axle center plane symmetry.Concrete, anti-on lock core inner core 1 twists groove 6 and to be opened on the 4th on marble hole 11 and the 5th between marble hole 11, and the anti-groove 6 of twisting on lock core shell 2 is opened between the 4th lower marble hole 21 and the 5th lower marble hole 21.
Shown in Figure 3, tumbler 3 comprises tumbler 31 and thumb wheel 32, and wherein, thumb wheel 32 is fixedly set in the outside of tumbler 31, and the inside of tumbler 31 is movably equipped with a pushing block 33 vertically, and tumbler 31 offers some fall shell hole.
Shown in Fig. 3 and Fig. 4, the two ends of lock core inner core 1 are respectively arranged with steel disc 13, and on steel disc 13 corresponding one group in end and this end residing for it between marble hole 11.Concrete, the thickness of steel disc 13 is 1.2mm ~ 1.4mm, and hardness is HRC57 ~ 62.
The anti-anti-theft lock of twisting of the utility model possesses three grades of anti-stubborn anti-theft features:
The first order is anti-stubborn antitheft, lock core inner core 1 two ends place arranges steel disc 13, and its thickness is 1.2mm ~ 1.4mm, and hardness is HRC57-62, be provided with one group of anti-drill pin 5 between lock core shell 2 first lower marble hole 21 and the second lower marble hole 21, the distance between two anti-drill pin 5 is less than 3.0mm.Therefore, when stealer cannot pierce and take violence to twist lock, the anti-groove 6 of twisting on lock core inner core 1 will be caused to rupture, hinder stealer to continue violence and twist lock.
The second level is anti-stubborn antitheft, lock core shell 2 and lock core inner core 1 to lay respectively between the 5th lower marble hole 21 and the 6th lower marble hole 21, two groups of anti-drill pins 5 on the 5th on marble hole 11 and the 6th between marble hole 11, distance often in group between two anti-drill pins 5 is less than 3.0mm, and anti-drilling number bullet on the 6th in marble hole 11 and anti-drilling flat nose, its hardness is HRC57-62.When stealer remain unchanged violence twist lock time, because lock core inner core 1 be segmental structure, the remainder of copper lock core inner core 1 is weaker, namely easily twists into two parts, and hinders stealer further violence to twist and locks.
The third level is anti-stubborn antitheft, when 1 structural break of lock core inner core, the reinforcement tack pellet 42 strengthened in marble hole 41 will drop, and anti-reinforcement stop pin 44 of twisting in intensive aspect 4 is subject to the thrust of spring 7, strengthen the top of stop pin 44 to snap in tumbler falls shell hole, thus play the effect of locking tumbler 31, indirectly pin thumb wheel 32, reach anti-theft function.In addition, the pushing block in tumbler 31 and anti-intensive aspect 4 of twisting are all through Technology for Heating Processing, and the violence of stealer is bored lock and also cannot be carried out, thus more firmly ensure that theftproof.
The utility model is not only confined to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the utility model or akin technical scheme, all within its protection domain.
