Realize and unlock, wherein, the unlocking bindiny mechanism includes intermeshing an interior clutch 8 and outer clutch 9, interior clutch
Be nested setting in interior lock gall with interior lock gall, and outer clutch is nested setting in outer lock gall with outer lock gall, interior clutch with it is interior
Interior clutch cushion block 10 is provided between lock gall axial direction, outer clutch cushion block is provided between outer clutch and outer lock gall axial direction
11, it is provided with interior clutch spring 12 between interior clutch cushion block and interior clutch, interior clutch spring pressure under original state
Clutch clutch direction movement outside with outer clutch makes interior clutch be in connection status, outer clutch with unlocking thumb wheel in compeling
Device is in disengaged position with unlocking thumb wheel, as shown in figure 4, lockpin hole 801 is provided with the interior clutch circumferential side wall,
The lock pin corresponding aperture corresponding with the lockpin hole is provided with the contiguous block, is provided with lock pin corresponding aperture and is pushed away by spring 13
Dynamic pin 14；As shown in fig. 7, when outside tapered end body is removed, in the compressing of interior clutch spring by outer clutch cushion block is destroyed
Clutch continues to move to the outside clutch direction of outer clutch, is just moved at lock pin corresponding aperture in lockpin hole, by spring
13 pins 14 promoted insert lockpin holes 801 and are connected interior clutch with unlocking thumb wheel locked, make lock core can only be from inner lock head body
It is normally-open.
In embodiment：There are the horizontal interior lock barrel 401 being oppositely arranged with one heart and outer institute's sleeve 402, institute on the contiguous block
State unlocking thumb wheel 3 to be arranged between interior lock barrel and outer institute's sleeve, interior lock barrel and outer institute's sleeve are respectively fitted over interior lock gall 5 and outer
The outside of lock gall 6.
In embodiment：The annexation of unlocking thumb wheel and interior lock gall and outer lock gall can have various ways, the present embodiment
One preferred scheme is achieved in that as shown in figure 3, the unlocking thumb wheel is provided with a through hole, and through hole is axially middle to be set
An annular protrusion 301 is equipped with, the through hole annular protrusion both sides hole wall on the outside of interior lock gall and on the outside of outer lock gall respectively with being nested
Connection, the horizontal end face of annular protrusion are used for and interior clutch and outer clutch connecting moves.Wherein, the unlocking thumb wheel through hole
Annular groove is respectively arranged between on the outside of annular protrusion both sides hole wall and interior lock gall and on the outside of outer lock gall, is set in annular groove
The steel ball sealing for having steel ball 15 to be formed between unlocking thumb wheel and interior lock gall and outer lock gall, which rolls, to be connected.
In Fig. 1, inner lock head body 1 and outside tapered end body 2 are connected by contiguous block 4 using 4 steel pins 16, and contiguous block 4 uses 45
Number steel modifier treatment hardness reaches HRC27 ~ 31.Contiguous block has enough width so that after outside tapered end body 2 is broken, contiguous block dew
In the outside of lock body, instrument is set not contact inside lock body.
In Fig. 2, Fig. 3, inside and outside lock gall 5 and 6 is attached by steel ball 15 and unlocking thumb wheel 3.The inside and outside appearance of lock gall 5 and 6
There is R0.65mm groove in face respectively, and unlocking thumb wheel corresponds to both sides therewith respectively R0.65mm groove, is put in two grooves
Enter 27 diameter 1.5mm steel ball 15 so that inside and outside lock gall 5 and 6 and thumb wheel are attached, such such as the mode of bearing
Connected mode can replace collar, eliminate the gap of collar so that in violence damage, the instrument such as screwdriver is nowhere set about.
In Fig. 3, under normality, under the effect of interior clutch spring 12, interior clutch 8 springs into the annular protrusion hole of thumb wheel 3 forever
It is interior to form linkage.As shown in figure 5, when indoor insertion key 7 pushes up interior clutch pad 10, clutch spring in pressure.Key is inserted into position, interior
Clutch and thumb wheel keep linkage in lock gall, rotate lock gall in key drive and rotate, so as to drive thumb wheel to rotate.
In Fig. 6, outside lock core during insertion key 7, outer clutch pad 11 is promoted, outer clutch moves inward, outer clutch
Device enters in thumb wheel annular protrusion hole, while interior clutch is ejected thumb wheel annular protrusion hole by clutch spring in compressing, in releasing
The linkage of clutch and thumb wheel.The linkage of outer clutch and thumb wheel is realized, so as to realize the excessively outer clutch of external lock Hymecromone and thumb wheel
Linkage.Rotating key 7 drives outer lock gall to rotate, so as to drive thumb wheel to rotate.
In Fig. 7, when in violence damage, outer lock gall can be broken at easy fault trough, at this moment outer clutch and interior clutch meeting
It is displaced outwardly under the active force of interior clutch spring, its displacement is just by the steel pin hole of clutch in steel pin nail alignment.
Steel pin inserts in the lockpin hole 801 of interior clutch under the force of a spring.At this moment, interior clutch still links with interior lock gall, from
And thumb wheel is locked.In addition, because outer lock gall still has part to be retained in contiguous block, wanting destruction clutch still has certain be stranded
It is difficult.At this moment, normally-open lock core is remained to from inside using key.
By described above, the structure against damages and motion principle of whole lock core are specify that, and by violence damage
The operation principle opened is prevented afterwards.
In the present embodiment, as shown in figure 3, having the T-shaped hoodle 17 of a row in the inside and outside lock gall, T-shaped hoodle heads on elasticity
Plug blades 18, after correct key, which drives, to be inserted, T-shaped hoodle can just be moved down, and at this moment lock gall is swung to necessarily in or beyond rotation
Position when, plug blades 18 can just be fallen, and interior lock gall or outer lock gall could rotate.
Wherein：In embodiment, the pellet includes key pellet 18, and key pellet 18 is higher by 1mm than other pellets, made
" Bob " key can not be touched by obtaining key pellet, so as to realize the purpose of " anti-Bob ".
