Interior swivel becket 20 (as shown in Figure 11,12) is assembled with the periphery activity of lock core 1, rotatably.The inboard end of interior swivel becket 20 and ring 2 (as shown in Figure 19,20) fixingly assemble, synchronous axial system.Outer swivel becket 17 assembles with the periphery activity of interior swivel becket 20, can rotate on interior swivel becket 20.There is 1 opening 26 (as shown in Figure 5,6) the inboard end of outer swivel becket 17, the periphery of outer swivel becket 17 is fixed with drive pin 3 and return pin 24.The jag of ring 2 is arranged in opening 26, simultaneously also between drive pin 3 and return pin 24.Return pin 24 is connected with one end of reset tension spring 25, and the other end of reset tension spring 25 is connected with extension spring steady pin 34.
Lock core 1, interior swivel becket 20 and outer swivel becket 17 all have 24 marble holes, and form 24 groups of marble holes, in cross arrangement, static lower each group of marble hole all communicates, often organize in marble hole and 4 round bead shape pellets are all housed, 1 columniform long marble and 1 spring, the length of long marble equals thickness and the 5mm of interior swivel becket 20, and be 2 times of round bead shape billiards diameter (2.5mm), 3 round bead shape pellets are all housed in each marble hole of lock core 1, and outmost pellet flushes with lock core 1 periphery height, in 24 groups of marble holes of interior swivel becket 20 and outer swivel becket 17, wherein 12 groups of orders loading pellet and spring are from inside to outside: 1 long marble, 1 round bead shape pellet and 1 spring, another 12 groups from inside to outside loading order be: 1 round bead shape pellet, 1 long marble and 1 spring, namely 12 long marbles are had to be across between interior swivel becket 20 and outer swivel becket 17.In fig. 2, have the round bead shape pellet (diameter 3mm) that 1 larger in outer swivel becket 17, predominant use is that in helping, swivel becket 20 is located mutually with outer swivel becket 17.In the present embodiment, as without this larger pellet, namely all round bead shape billiards diameters are 2.5mm, and the performance of lockset is constant.
Under static state, the jag of ring 2 contacts with the top edge of opening 26, contacts with spacer pin 32 simultaneously.Under the pulling force effect of reset tension spring 25, interior swivel becket 20 all keeps transfixion state with outer swivel becket 17, and 24 groups of marble holes all keep communicating state, it is stressed all identical for all round bead shape pellets now in lock core 1, cannot judge which pellet should move a billiards diameter distance or not.
The two ends of camshaft 7 (as shown in Figure 23,24) are assembled with the axis hole activity of anti-skid plate 21, backboard 22 respectively.Apical axis 9 (as shown in Figure 21,22) two ends respectively with the top peg-in-hole assembly of anti-skid plate 21, backboard 22, for limiting the spacing of anti-skid plate 21, backboard 22, camshaft 7 can be rotated.As shown in Figure 2, the limiter of moment assembled with camshaft 7 forms primarily of cam 11, rotating plate 15 (as shown in Figure 17,18) and driven disc 14 (as shown in Figure 15,16), and adopts collision bead 16, lost motion springs 6 supporting structure mode.Wherein, rotating plate 15 assembles with camshaft 7 is fixing, driven disc 14 assembles by screw is fixing with cam 11, therebetween movable assembling rotating plate 15, when the moment of torsion putting on camshaft 7 exceedes limiting design value, rotating plate 15 overcomes the thrust of lost motion springs 6, collision bead 16 is made a concession in hole mobile, camshaft 7, rotating plate 15 dally, and cam 11 does not rotate.When the rotating plate of limiter of moment, driven disc adopt punching press fin plate and axially push away spring supporting structure mode, its manufacturing cost is lower, just in processing technology, needs pressing equipment and mould.
As shown in Figure 25,26,27, the innermost end of cam 11 is provided with upper flange 27, and adjacent inboard lower end is lower flange 28.Driving lever 4 is hinged with the inboard end of camshaft 7, and with the inboard end face movable contact of cam 11, the finger 5 of unblanking of the inboard end of cam 11, finger 8 of locking lay respectively at the both sides of driving lever 4, unblank for promoting driving lever 4 reciprocally swinging and then completing and lock.
The process of unblanking inserts key (as shown in Fig. 9,10), but non rotating key, unblanked by rotary handle.Principle of unblanking is as follows: no matter whether correct (alleged key is incorrect here for key, refer to that the crest of key or the height of trough or the degree of depth are identical with correct key, difference be the position of crest or trough have at least one incorrect), interior swivel becket 20 all can rotate on lock core periphery, now because the jag of ring 2 contacts with the top edge of the opening 26 of outer swivel becket 17, when rotary handle, camshaft 7 makes cam 11 rotate by limiter of moment, the upper flange 27 of cam 11 first contacts with the jag of ring 2 and promotes it and rotates, interior swivel becket 20, outer swivel becket 17 follows ring 2 synchronous axial system.After cam 11 rotates 15 degree of angles, the upper flange 27 of cam 11 disengages with the jag of ring 2, turn 3 ~ 5 degree of angles again, the lower flange 28 of cam 11 contacts with the drive pin 3 on outer swivel becket 17, turn 3 ~ 5 degree of angles again, the jag of ring 2 contacts with latch 33 and stops operating, and namely, swivel becket 20 stops operating, and lower flange 28 promotes drive pin 3 and outer swivel becket 17 rotates separately afterwards.If key is correct, outer swivel becket 17 can continue to rotate 15 degree of angles separately, and the lower flange 28 of cam 11 also disengages with drive pin 3 afterwards, and cam 11 can be rotated further and then promote driving lever 4 and swing, realizes unlocking action; If key is incorrect, have at least a long marble to be between interior swivel becket 20, outer swivel becket 17, stop outer swivel becket 17 to rotate separately, cam 11 can not be rotated further, and lockset can not be opened.When putting on the moment of torsion on camshaft 7 and exceeding limiting design value, camshaft 7 dallies, and cam 11 does not rotate, and lockset still can not be opened.When without in key situation, have between interior swivel becket 20, outer swivel becket 17 12 long marbles stop both relatively rotate, handle, camshaft 7 dally, and lockset still can not be opened.
In the present embodiment, the synchronous axial system angle of interior swivel becket 20, outer swivel becket 17 is: 15+ (3 ~ 5)=18 ~ 20 degree angle; The independent rotational angle of outer swivel becket 17 is 15 degree of angles; The relative rotation of interior swivel becket 20, outer swivel becket 17 is 15 degree of angles; When lower flange 28 and drive pin 3 disengage, the total angle of rotation of cam 11 is: 15+ (3 ~ 5)+degree angle, (3 ~ 5)+15=36 ~ 40, and the total angle of rotation of outer swivel becket 17, return pin 24 is: degree angle, 15+ (3 ~ 5)+15=33 ~ 35; The width of the opening 26 of outer swivel becket 17 should make interior swivel becket 20, the relative rotation of outer swivel becket 17 is greater than 15 degree of angles and can satisfies the demand, and in fact select larger opening 26 width, on lockset performance without impact, but must ensure that the upper marginal position of opening 26 is accurate, each group of marble hole of interior swivel becket 20, outer swivel becket 17 could be made in the quiescent state to communicate completely, thus ensure lockset performance.Same reason, the position of spacer pin 32 also must accurately, and the marble hole of overall lockset all pellet groups in the quiescent state just can be made to communicate all completely, namely with the hole heart.
After lower flange 28 and drive pin 3 disengage, cam 11 rotates 50 degree of angles again and namely completes lockset unlatching by driving lever 4, therefore the total angle of rotation of cam 11 is: (36 ~ 40)+50=86 ~ an angle of 90 degrees, namely rotatable handle 86 ~ an angle of 90 degrees can complete unlocking action.
Lockset reversely rotates handle after opening and gets back to home position, and the reseting procedure of interior swivel becket 20, outer swivel becket 17 relies on the pulling force of reset tension spring 25 to complete.Process of locking, without key, reversely rotates handle 50 degree of angles and has come.
Above-mentionedly unblank in process, first make interior swivel becket 20, outer swivel becket 17 misplace with lock core 1 simultaneously, then drive unlocking mechanism to unblank, therefore can cannot open lockset by actualizing technology.
When using the tool that goes into operation by force to insert lockhole, the cross bore of anti-skid plate 21 stops opens tool into rotation by force, exempts from destruction in order to protect lock core.
Backboard two ends are provided with installing hole 23, are fixedly mounted by the installing rack 10 on bolt and door body.Installing rack 10 is welded on a body stiffener 13.
Figure 28 is the dislocation driving type mechanical anti-theft lock assembling schematic diagram that lock core can rotate, the periphery of lock core 1 is followed successively by retainer ring and outer swivel becket 17, wherein retainer ring and backboard 22 assemble so that screw is fixing, erection loop 35 one end contacts with backboard 22, a side of the other end and connecting ring 36 is assembled, another side and the door body lockhole of connecting ring 36 assemble, and overall lockset is fixed on installing rack 10.After lock body is fixing, lock core 1, outer swivel becket 17, ring 2, anti-drilling sheet 18 are all rotatable.When the width of the tool that goes into operation by force inserting lockhole makes the distance moved in the marble hole of retainer ring of the pellet in lock core 1 be greater than pellet radius, lock core is rotatable, and the long marble between retainer ring, outer swivel becket 17 bears shearing force; When the width of the tool that goes into operation by force makes the distance moved in the marble hole of retainer ring of the pellet in lock core 1 be less than pellet radius, lock core can not rotate, and the inner headed face of lock core and retainer ring bears the destructive power of the tool that goes into operation by force, therefore can not ensure that lockset stands intact.
