Abstract
The invention relates to a 360 DEG idle rotating theftproof cylinder, aiming at the problem that the prior cylinder can not prevent a lock from unlocking by violently rotating the cylinder, thereby the theftproof function of the 360 DEG idle rotating theftproof cylinder is definite, namely the whole cylinder can perform 360 DEG idle rotation while a twelve-hole disc unlocking torsion bar mechanism does not rotate when a flatheaded tool is used for violently rotating the cylinder, consequently the aim of preventing violent unlocking is achieved. The key points of solving the problem of idle rotation and theft protection of the cylinder is as follows: key mechanisms are a convex tooth 6 and the twelve-hole disc unlocking torsion bar mechanism. A lock core can be pushed in only by inserting a correct key and simultaneously only the convex tooth 6 can be joined with a twelve-hole disc, thereby a lock can be unlocked by rotating the key at the time. When an inserted key is not correct, thelock core can not be pushed in and the convex tooth 6 can not be joined with the twelve-hole disc and is in the disconnecting state, thereby the whole cylinder can perform idle rotation if violence is used for rotating the cylinder at the time and the twelve-hole disc unlocking torsion bar mechanism does not rotate, consequently the lock can not be unlocked.
Description
Technical field: solve traditional tapered end and rotate the shortcoming that just can unblank by force, utilize the lock core pushing style, the method for attachment that the utilization double wedge inserts the free rotary disk in 12 holes is carried out mechanical connection and is unblanked.Utilization key return is pulled out key with the mode of stop screw return, and the disengagement with 12 hole circle dishes is connected with double wedge.
Background technology: traditional tapered end does not have anti-theft feature, just can unblank with a word cross instrument violence rotational lock head.At this point defect, I just invention transform traditional tapered end, rotational lock head is not all opened.
Summary of the invention: exactly traditional tapered end is undergone technological transformation.The vitals of invention is Fig. 1,2,3,4.Each parts link position and relation indicate as Fig. 5 figure, 6 figure.
Description of drawings: elevation 4 width of cloth: Fig. 1, Fig. 2, Fig. 3, Fig. 4.Be vitals, side sectional view two width of cloth: Fig. 5, Fig. 6.
Fig. 1: the free rotation disk mechanism in 12 holes.Fig. 2: double wedge incision mechanism.Fig. 3: tapered end is fastening with convex support (the free rotating disk of two-layer interlock of middle band screw hole).Fig. 4: the free rotary disk spring-damper in 12 holes.

The specific embodiment: as shown in Figure 5, when inserting lock core with a word instrument, key is not right, and lock core pushes away to go into, and double wedge 6 is inserted not go in the arbitrary hole of free rotary disk, 12 holes, is exactly not connect.So rotational lock core, lock core drive free rotating disk 9 synchronous idles of two-layer interlock on whole tapered end and the convex support.So do not drive lock.Because the effect of damper makes the free rotary disk of torsion bar 18 and 12 holes of unblanking motionless.As shown in Figure 6, when inserting lock core with correct key, lock core pushes away to such an extent that go into, being pushed into stop screw 4 pushes up till the round spacing base plate 24, at this moment double wedge 6 is inserted in the arbitrary hole of free rotary disk, 12 holes, promptly links together, and at this moment rotates key, lock core drives the free disk in 12 holes and the torsion bar 18 of unblanking rotates, and can unblank.Owing to stop screw 4 is arranged in groove 15 positions, so key can not pull in the process of normally unblanking, guarantee that double wedge 6 and 12 hole circle dishes do not throw off in the process of unblanking, have only the key return, stop screw 4 ability returns, just can pull out key 25, double wedge 6 is just thrown off with 12 hole circle dishes, as Fig. 5 state.
Claims (1)
1. spend idle rotation type theft-proof lock for one kind 360, described 360 degree idle rotation type theft-proof locks utilize the lock core pushing style, utilization double wedge (6) inserts the method for attachment of the free rotary disk in 12 holes, carry out mechanical connection and unblank, utilization key return is pulled out key and the free rotary disk disengagement in double wedge and 12 holes is connected with the mode of stop screw return; It is characterized in that: when inserting lock core with a word instrument, because key is not right, lock core pushes away to go into, double wedge (6) can not insert in the arbitrary hole of free rotary disk, 12 holes, both do not connect, this moment rotational lock core, lock core drives the free rotating disk of two-layer interlock (9) synchronous idle on whole tapered end and the convex support, does not drive lock; Wherein because the effect of damper, make the free rotary disk in 12 holes and the torsion bar of unblanking (18) that connects together with described rotary disk motionless; When inserting lock core with correct key, lock core pushes away to such an extent that go into, push till stop screw (4) pushes up round spacing base plate (24), at this moment double wedge (6) is inserted in the arbitrary hole of free rotary disk, 12 holes, both link together, rotate key this moment, lock core drives the free rotary disk in 12 holes and the torsion bar (18) of unblanking rotates, and realizes unblanking; In the process of unblanking, owing to stop screw (4) is arranged in groove (15) position, so key can not pull in the process of normally unblanking, thereby assurance double wedge (6) is not thrown off in the process of unblanking with the free rotary disk in 12 holes, have only the key return, stop screw (4) ability return just can be pulled out key (25), and the free rotary disk of double wedge (6) ability and 12 holes is thrown off; Each bore edges beveling of the free rotary disk in described 12 holes is convenient to the double wedge incision, finishes mechanical connection in the hole thereby slip into.
