The specific embodiment:

Several embodiment of idle-run lock pin described in the utility model comprise key 1, stopping device 2, rotation lock tube 3, resistance steel ball 4, inclined-plane 5, lock core 6, male and fomale(M﹠F) 7, dead bolt 8, stage clip 9, jump ring groove 10, lock body 11, pit 12, dead bolt hole 13, jump ring 14, resistance shell fragment 15, sliding pin 16, chute 17, dead bolt pin 18, blade-rotating dead bolt 19. altogether

Most preferred embodiment one of the present utility model as shown in Figure 1, from the structure chart as can be seen, described idle-run lock pin is mainly by key 1, stopping device 2, rotation lock tube 3, resistance steel ball 4, lock core 6, male and fomale(M﹠F) 7, dead bolt 8, lock body 11 is formed, described rotation lock tube 3 is movably arranged in the lock body 11 and stopping device 2 is equipped with at cylindrical or place, outer end, stopping device 2 is made of the jump ring groove 10 in jump ring 14 and anti-drilling sheet 2 and the lock body 11, the tail end male and fomale(M﹠F) of rotation lock tube 3 is inclined-plane 5, the tail end of lock core 6 is provided with groove, with on the contacted dead bolt 8 of these two faces also be complementary with it male and fomale(M﹠F) 7, the front end of dead bolt 8 is actively set in the dead bolt hole 13 of lock body, be with stage clip 9 on the dead bolt 8, dead bolt 8 overcomes the resistance of stage clip 9 under external force and makes shift reciprocately; The breech face that has only rotary sleeve 3 in the described present embodiment is the inclined-plane, and all the other two are straight shape male and fomale(M﹠F), and the male and fomale(M﹠F) 7 on the described dead bolt 8 contacts simultaneously with the male and fomale(M﹠F) of lock core 6 with rotation lock tube 3 tail ends.

In the utility model, male and fomale(M﹠F) can be groove, inclined plane groove, curved surface groove, helicoid groove, also can be raised line, convex inclined plane body, convex surface body, helicoid convex body etc.

The operating principle of idle-run lock pin: owing to pass through the effect of resistance steel ball 4 and pit 12 between lock body 11 and the rotation lock tube 3, can rotate between lock body 11 and the rotation lock tube 3, but the bigger moment of resistance is arranged, moment of resistance maximum when particularly just having rotated; Insert normal key 1 and rotation, because key is right, lock core 6 is with respect to having only very little moment of friction between the rotation lock tube 3, and the moment of resistance that this moment of friction is compared between rotation lock tube 3 and the lock body 11 is much smaller, so lock core 6 just rotates in rotation lock tube 3, from Fig. 2, on Fig. 3 as can be seen, initial position is that the middle part higher part of protrusion is stuck in the groove of lock core 6 tail ends on the dead bolt 8, and the low part of protruding contacts with the highest part of rotation lock tube 3 afterbodys on dead bolt 8 limits, after lock core 6 turns over an angle (near the upright position), because lock core 6 blocks dead bolt 8, so dead bolt 8 can be with together by lock core 6 and rotate, and dead bolt 8 can pressed along the male and fomale(M﹠F) rotation of rotation lock tube 3 end faces by stage clip, when the male and fomale(M﹠F) of rotation lock tube 3 tail ends is inclined-plane 5, dead bolt 8 just can pressed along the inclined-plane 5 to do axial displacement by stage clip, thereby realizes the unlatching of lockset.Otherwise screw key 1 makes lock core 6 counter-rotatings, and dead bolt 8 just can outwards do to overcome the displacement of stage clip 9 vertically under the effect on inclined-plane 5.

Its antitheft principle that dallies: when using non-original key (profile of tooth not to) or sled to steal instrument, because the surface of shear resistance of lock core 6 and rotation lock tube 3 internal lock pellets shot from a slingshot makes between lock core 6 and the rotation lock tube 3 and can not rotate, so any axial displacement (because this displacement is to rely on the rotation between lock core 6 and the rotation lock tube 3 to reach) just can not take place in dead bolt 8 yet, and strengthen turning moment only can make rotation lock tube 3 overcome and lock body 11 between the rotation in lock body 11 after the moment of resistance that produces because of resistance steel ball 4 and pit 12, this rotation just makes dead bolt 8 rotate and can not be subjected to displacement, so lockset is not constituted a threat to.

The groove and the inclined-plane of

lock core

6 and 3 two part tail ends of rotation lock tube can exchange the role among the embodiment of the present utility model.

Most preferred embodiment two of the present utility model as shown in Figure 4, the tail end male and fomale(M﹠F) of a part in present embodiment and embodiment one male and fomale(M﹠F) that different is on the described dead bolt 8 and

rotation lock tube

3 or 6 two parts of lock core contacts, and dead bolt 8 also passes through sliding pin 16 with another part, chute 17 Poewr transmission mechanisms such as grade (also can pass through spline, the abnormity sleeve, Poewr transmission mechanisms such as keyway) movable inlay card, so dead bolt 8 can freely not rotate relative to this part, and only can do axial displacement along this part, what show among Fig. 5 is that lock core 6 has turned over 90 °, displacement has taken place to the right in the chute 17 of sliding pin 16 on the dead bolt 8 on rotation lock tube 3, snapped in because of the male and fomale(M﹠F) on the dead bolt 8 in the groove of lock core 6 tail ends, dead bolt 8 has also just been finished displacement, thereby realizes the switching of lock.

Most preferred embodiment three of the present utility model as shown in Figure 6, present embodiment is different with preceding several embodiment is that male and fomale(M﹠F) between its lock core 6 and the dead bolt 8 is a helicoid, its lock core 6 is provided with screw rod, dead bolt 8 is provided with nut, pass through sliding pin 16, chute 17 interaction inlay cards between dead bolt 8 and the rotation lock tube 3, can control the shift reciprocately of dead bolt 8 in the present embodiment by the rotation of lock core 6, and present embodiment can save stage clip 9, the moment of resistance is finished by resistance shell fragment 15 in the present embodiment.

Among the embodiment of the present utility model, the working method of the male and fomale(M﹠F) contact between lock core 6, dead bolt 8, the rotation lock tube 3 can also be selected the mode of Fig. 7 for use, both dead bolt 8 was a concave surface, its cylindrical axially has chute 17, on the rotation lock tube 3 sliding pin 16 is housed, the breech face of lock core 6 is a convex surface, and rotary locking cylinder 6 just can make with the dead bolt 8 that rotates lock tube 3 movable inlay cards and do axial displacement.

Among above-mentioned several embodiment of the present utility model, its dead bolt 8 mainly opens and closes lockset by displacement, and need open and close lockset by rotation to some, then needing to increase 1 part just can reach again, see Fig. 8 for details, on former dead bolt 8, set up dead bolt pin 18, add a blade-rotating dead bolt 19 in addition again, the shape hole that can embed the dead bolt 8 that has dead bolt pin 18 is arranged on the blade-rotating dead bolt 19, blade-rotating dead bolt 19 is concentric with dead bolt 8, when snapping in the shape hole on the blade-rotating dead bolt 19 when being subjected to displacement under the drive of dead bolt 8 at key (as shown in Figure 9), will make lock core 6 (or rotation lock tube 3) drive dead bolt 8 commentaries on classics together after having overcome the moment of resistance together if be rotated further key, thereby also having driven blade-rotating dead bolt 19 rotates together, blade-rotating dead bolt 19 just can drive lockset and work together, if this lock key of right and wrong that uses, or use unlocking tool, do not rotate between lock core 6 and the rotation lock tube 3, axial displacement just can not take place in dead bolt 8 yet, because the dead bolt pin 18 on the dead bolt 8 does not snap onto in the shape hole of blade-rotating dead bolt 19, so the rotation of dead bolt 8 can't drive blade-rotating dead bolt 19 and rotate, and what really drive lockset work is blade-rotating dead bolt 19, so lockset just can not be opened yet.

Embodiment four of the present utility model as shown in figure 10, what present embodiment was different with other embodiment is that its dead bolt 8 passes through sliding pin 16 and the movable each other inlay card of chute 17 with lock body 11, lock core 6 has groove or boss with rotation lock tube 3 on contour plane, also corresponding boss or the groove of having on the contact surface of dead bolt 8 and these two parts, because lock core 6 is contour planes with the tail end of rotation lock tube 3, so when two grooves orthogonal (or near vertical), its dead bolt 8 can block, this moment with non-original key such as instrument unblank (because of lock core 6 big with the shearing resistance of rotating pellet shot from a slingshot between the lock tube 3, only can make rotation lock tube 3 overcome and lock body 11 between be forced to rotation after the moment of resistance of

resistance steel ball

4 and 17 of chutes, here vertical chute can replace the function of pit 12), owing to do not rotate between lock core 6 and the rotation lock tube 3, and two its projections of concave surface that intersect are contour, two tail end planes that is to say lock core 6 and rotation lock tube 3 are complementary, and dead bolt 8 contacts simultaneously with contacting of these two parts, so the projection of dead bolt 8 can not be trapped in the groove of lock core 6 and rotation lock tube 3, rotary locking cylinder 6 can not make dead bolt 8 be subjected to displacement yet arbitrarily, and lockset just can not be opened yet.When with normal key unlocking, lock core 6 and the frictional force of rotation between the lock tube 3 than rotation lock overlap 3 and the moment of resistance of 17 of 11 resistance steel balls 4 of lock body and chutes much smaller, so lock core 6 is rotation between rotation lock tube 3 just, because of the inclined-plane relation, lock core 6 is in the process of rotation, dead bolt 8 just snaps in the groove of other two parts along the inclined-plane under the effect of stage clip 9 gradually, and dead bolt 8 just is subjected to displacement, and lock just can be opened.In the present embodiment because dead bolt 8 and lock body 11 movable inlay cards, so dead bolt 8 can't rotate, so present embodiment also just can't be implemented on the lockset of unblanking with rotation.Stopping device adopts on the cylindrical of rotation lock tube 3 and in the hole of lock body 11 jump ring groove 10 is set in the present embodiment, and the jump ring groove 10 of these two parts in device jump ring 14, rotate and can only rotate between lock tube 3 and the lock body 11 and can not withdraw from.

The utility model is simple in structure, part is few, safe.
