[detailed description of the invention]
The present invention is a kind of lock core having anti-collision simultaneously and instigate technical opening function, as shown in Figures 1 to 3, include lock housing 1, lock gall 2, be located at several hoodle assemblies 3 in lock housing 1 and lock gall 2, described hoodle assembly 3 includes plug 31, pearl spring 32, flat pearl 33 and hoodle 34, in order to realize the technical opening of anti-collision, have at least a hoodle assembly 3 to be anti-collisioves and instigate unlatching, the hoodle 34 of the hoodle assembly 3 that each anti-collision and instigation are opened is made up of with the cover pearl 342 be socketed in outside the pillar 3411 of lower pearl 341 the lower pearl 341 of " convex " font, described cover pearl 342 vertically slides flexibly on this pillar 3411 outer wall, instigate to prevent robber and unblank, in the middle part of described cover pearl 342, outer wall is provided with anti-instigation groove 3421, when described cover pearl instigates top, its lower end still has 0.1mm(at least preferably between 0.3 to 1mm) the degree of depth ensconce in the hole of bead 21 of this lock gall 2, namely at this moment overlap the depth H of ensconcing the hole of bead 21 of this lock gall 2 in pearl lower end and have 0.1mm(at least preferably between 0.3 to 1mm), as shown in Figure 5.
When lock core is in the lock state, if insert lock core with impact tool 4 and start to clash into, impact tool impacts lower pearl 341, then pearl 341 impact sleeve pearl 342 is again descended, then overlap pearl and impact again flat pearl 33, due to the restriction by stroke and pearl spring and by cover pearl Gravitative Loads, cover pearl 342 can not detach pillar when vertically sliding on this pillar 3411 outer wall all the time, to overlap after being impacted like this in the hole of bead 21 that pearl 342 enters lock housing 2 at once and some is enclosed within the pillar 3411 of lower pearl 341 all the time, this under impact events, namely the length that cover pearl 342 is equivalent to increase flat pearl become a part for flat pearl, so at this moment overlapping pearl 342 is functionally be stuck in all the time between lock housing and lock gall as the cover pearl of a flat pearl part, when impact tool as Fig. 4 up hits and resets downwards shown in two states, if and now wanted opening lock master must rotate impact tool 4, cover pearl 342 will clamp once rotation and be stuck between lock housing 1 and lock gall 2, so cannot opening lock master by impact tool 4, when impact tool return, the hoodle be made up of lower pearl 341 and cover pearl 342 also will get back to lock-out state, and at this moment flat pearl 33 is stuck between lock housing and lock gall again, thus reaches the object of anti-collision opening lock master.
We know, during robber's technology unlocking except shock is above unblanked, one is also had to be instigate to unblank, they are when instigateeing hoodle opening lock master, what adopt is provoke hoodle with feeling, just thinks can rotate lock gall to open when provoking hoodle and feeling that to a certain position hoodle top is just concordant with lock gall outer wall.In the present invention, when robber to instigate open time, he provokes while cover pearl 342 makes it to slide outward and rotates clockwise lock gall 2 a little, at this moment the side overlapping pearl 342 is adjacent on the sidewall of lock housing 1 and lock gall 2, along with cover pearl 342 rise to the lower end of its anti-instigation groove 3421 time, the top, the hole of bead that have rotated little low-angle lock gall 2 is just slipped in anti-instigation groove 3421 and produces obvious feel, at this moment robber just thinks and instigates successfully, so be rotated further lock gall, but the lower surface of anti-instigation groove 3421 is made just to hang on the bottom wedge angle 111 in the hole of bead 11 of lock housing 1, as Fig. 6, shown in 7, so cause cannot being rotated further lock gall to open, thus the effect that the technological means playing anti-instigation is opened.
As can be seen from above, when clashing into, instigateeing opening lock master, cover pearl 342 functionally plays the effect of flat pearl, so namely the length that cover pearl 342 is equivalent to increase flat pearl become a part for flat pearl, be at this moment stuck in all the time between lock housing 1 and lock gall 2 as the cover pearl of a flat pearl part and prevent from the person's of unblanking rotational lock core to open; And when correct key operated time, cover pearl returns to the effect of hoodle, just can rotate lock gall to open when flat pearl is up shifted onto just tangent with lock gall position, its bottom surface by it.
As shown in Figure 5, be respectively equipped with " eight " font to slip into introducing port 3423 and slip into import 3412 in described cover cover hand-hole 3422 bottom of pearl 342 bottom and pillar 3411 top of lower pearl 341, such instigation opens frustrated robber once stop instigateeing, under the effect of pearl spring, be slipped to again after the cover pearl of inclined hanging on the bottom, the hole of bead of lock housing just can ajust reset more smoothly outside the pillar 3411 of lower pearl 341, thus avoid because of be subject to external force instigate after cover pearl cannot ajust reset and scrap whole lock core situation occur, also just improve the application life of lock core.
Anti-instigation groove 3421 on cover pearl 342 has one to three groove usually, the hoodle assembly 3 that described anti-collision and instigation are opened has two or more, the groove number of the anti-instigation groove 3421 on the cover pearl 342 of the hoodle assembly 3 that adjacent anti-collision and instigation are opened is different, such robber just cannot find out each hoodle assembly and instigate the rule of opening, thus further increases the theftproof performance of lock core.
Under normal circumstances, described cover pearl 342 is pillar 3411 concordant or a little higher than with described pillar 3411 when reset mode, and that is pillar is not too short, and object is to avoid cover pearl to be separated with pillar when clashing into and opening.
Owing to producing the error of component and assembling, preferably, the mode that described plug 31 is arranged to be threaded is screwed in the hole of bead 11 of this lock housing, the screwdriver insertion groove 311 of indent is provided with in the upper surface of described plug 31, like this when producing lock core, just can be inserted in screwdriver insertion groove 311 with screwdriver and turning plug 31 at any time and regulate, guarantee to overlap its lower end when pearl instigates top and still have at least the length of 0.1mm to ensconce in the hole of bead 21 of this lock gall 2.
