Abstract
The invention relates to a cross mechanical anti-theft lock with a fixed lock cylinder. The lock comprises a prying resistant plate, a drilling resistant piece, a backboard, a lock cylinder, an inner rotary ring, an outer rotary ring, a dialing ring, a moment limiter, a cam shaft and a matched key. The lock is mainly characterized in that the lock cylinder is fixedly assembled between the prying resistant plate and the backboard and cannot move. Driven by the cam, the inner and outer rotary rings at the periphery of the lock cylinder synchronously rotate an angle of 15 degrees first and are staggered with the lock cylinder, and then the outer rotary ring continuously rotates independently and unlocks, so that the lock cannot be unlocked technically. The prying resistant plate is located outside the lock cylinder, and a cross hole is formed in a position corresponding to the prying resistant plate, so that the lock is prevented from being destructively unlocked by a forced unlocking tool. The moment limiter can idle when a handle is rotated with brute force, so that the lock is prevented from being damaged and cannot be unlocked. The unlocking process comprises the following steps: inserting the key without rotating the key and rotating the handle for 90 degrees. The lock is locked without the key and in a way of reversely rotating the handle for an angle of 50 degree.

Interior swivel becket 20 (as shown in Figure 11,12) assembles with the periphery activity of lock core 1, rotatable.The inboard end of interior swivel becket 20 and the fixing assembling of ring 2 (as shown in Figure 19,20), the rotation of synchronizeing.Outer swivel becket 17 assembles with the periphery activity of interior swivel becket 20, can on interior swivel becket 20, rotate.There is 1 opening 26 (as shown in Figure 5,6) the inboard end of outer swivel becket 17, is fixed with drive pin 3 and return pin 24 on the periphery of outer swivel becket 17.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.
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, now it is stressed all identical for all round bead shape pellets in lock core 1, cannot judge which pellet should move a billiards diameter distance or not.
Assemble with the axis hole activity of anti-skid plate 21, backboard 22 respectively at the two ends of camshaft 7 (as shown in Figure 23,24).Assemble with the apical axis hole of anti-skid plate 21, backboard 22 respectively at apical axis 9 (as shown in Figure 21,22) two ends, 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 assembling with camshaft 7 is mainly comprised 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 modes.Wherein, rotating plate 15 and the fixing assembling of camshaft 7, driven disc 14 is fixed assembling with cam 11 by screw, movable assembling rotating plate 15 between the two, when putting on the moment of torsion of camshaft 7 and exceed limiting design value, rotating plate 15 overcomes the thrust of lost motion springs 6, makes collision bead 16 mobile to making a concession in hole, camshaft 7, rotating plate 15 dally, and cam 11 does not rotate.When rotating plate, the driven disc of limiter of moment adopt punching press fin plate and axially push away spring supporting structure mode, its manufacturing cost is lower, just aspect 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 inside 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 cam 11 inboard ends, the finger 8 of locking lay respectively at the both sides of driving lever 4, for promoting driving lever 4 reciprocally swingings and then completing, unblank and lock.
The process of unblanking is to insert key (as shown in Fig. 9,10), but does not rotate key, by rotary handle, unblanks.The 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 top edge of the jag of ring 2 and the opening 26 of outer swivel becket 17 contacts, when rotary handle, camshaft 7 rotates cam 11 by limiter of moment, the upper flange 27 of cam 11 first contacts and promotes its rotation with the jag of ring 2, interior swivel becket 20, outer swivel becket 17 is followed ring 2 and is synchronously rotated.Cam 11 rotates behind 15 degree angles, the upper flange 27 of cam 11 disengages with the jag of ring 2, turn again 3～5 degree angles, the lower flange 28 of cam 11 contacts with the drive pin 3 on outer swivel becket 17, turn again 3～5 degree angles, the jag of ring 2 contacts and stops operating with latch 33, in swivel becket 20 stop operating, 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 separately 15 degree angles, 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 moment of torsion on camshaft 7 and exceed limiting design value, camshaft 7 dallies, and cam 11 does not rotate, and lockset still can not be opened.In without key situation, between interior swivel becket 20, outer swivel becket 17, there are 12 long marbles to stop relatively rotating of the two, handle, camshaft 7 dally, and lockset still can not be opened.
In the present embodiment, the synchronous rotational angle of interior swivel becket 20, outer swivel becket 17 is: 15+ (3～5)=18～20 spends angle; The independent rotational angle of outer swivel becket 17 is 15 degree angles; The relative rotation of interior swivel becket 20, outer swivel becket 17 is 15 degree angles; When lower flange 28 disengages with drive pin 3, the total angle of rotation of cam 11 is: degree angle, 15+ (3～5)+(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 the relative rotation of interior swivel becket 20, outer swivel becket 17 be greater than 15 degree angles can to satisfy the demand, and in fact select larger opening 26 width, on lockset performance without impact, but must guarantee that the upper marginal position of opening 26 is accurate, could under static state, make each group of marble hole of interior swivel becket 20, outer swivel becket 17 communicate completely, thereby guarantee lockset performance.Same reason, the position of spacer pin 32 also must be accurately, just can make the marble hole of overall lockset all pellet groups under static state all communicate completely, with the hole heart.
After lower flange 28 disengages with drive pin 3, cam 11 rotates 50 degree angles again can complete 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, rotatable handle 86～an angle of 90 degrees can complete unlocking action.
Lockset counter-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.The process of locking is without key, and reverse rotation handle 50 is spent angle and completed.
Above-mentioned unblanking in process, first makes interior swivel becket 20, outer swivel becket 17 misplace with lock core 1, then drives unlocking mechanism to unblank simultaneously, therefore can realize technology, cannot open lockset.
When using the tool that goes into operation by force to insert lockhole, the cross bore of anti-skid plate 21 stops the tool that goes into operation by force to rotate, in order to protect lock core to exempt from destruction.
Backboard two ends are provided with installing hole 23, by bolt and the installing rack 10 on door body, fixedly mount.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 are with the fixing assembling of screw, erection loop 35 one end contact with backboard 22, a side assembling of the other end and connecting ring 36, the another side of connecting ring 36 and the assembling of door body lockhole, 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 inserting the width of the tool that goes into operation by force of lockhole and make pellet in lock core 1 move into distance in the marble hole of retainer ring to 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 pellet in lock core 1 move into distance in the marble hole of retainer ring to 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 guarantee that lockset is excellent.
