The specific embodiment

Among the application, the position of stuck point, jump ring preferred at random (must be straight even distribute, distance each other also with at random be good), also have lockset and the position of key and the structure of the locking of unblanking now.

Among Fig. 1, interior jump ring 5 is arranged on the internal cylinder 2 of lockset shell 1 end, internal cylinder accounts for about half of lock core depth (1/100-99/100 all can, also can only keep top outer lock core and internal cylinder) substantially, and outer lock core 3 is positioned at shell front end place, forms lock core jointly.Internal cylinder is connected with the matte 3 that is positioned at outer lock core.Matte can cover the jump ring on (even pushing down) outer lock core, and similar to the outer lock core inner wall shape, and matte two inclines are done suitable processing, helps matte and rotates.Matte has only certain area, and can cover part or all of (preferably) outer jump ring 6. outer lock core front end faces and housing contacts place can have the top jump ring, in the jump ring of top matte can be arranged, and matte can cover the part front end face.Can there be jump ring 7 in the top position that front end face is not covered, and it (is fan-shaped or semicircle or semicircle add fan-shaped that the front end face internal cylinder at jump ring place in outer jump ring 8. tops, top can be arranged below the matte.Do not draw in detail among the figure) on same plane, perhaps the front end face internal cylinder is in the front end face outer lock core with the front end face outer lock core (not drawing not fan-shaped semicircle or the semicircle or fan-shaped of adding among the figure in detail) of locating jump ring 8 places.If the total angle of key turns deducts the top internal cylinder smaller or equal to 360 degree and deducts the fan-shaped angle of top outer lock core again, then both can be on a plane; Otherwise after must one previous.Both respectively with corresponding internal cylinder, outer lock core connects; If do not connect, must have on the key then that (outward) lock core interacts in corresponding phase card structure (below detailed presentations is arranged) and the top, make (outward) lock core energy normal rotation in the top, reset.

Internal cylinder has card structure (not drawing among the figure) mutually with outer lock core.Key drive internal cylinder turns to outer stuck point 16 and 6 pairs of outer jump rings are seasonable, and the protrusion or the recess of both last settings block mutually, and internal cylinder drives outer lock core and rotates, until opening lockset.So, between internal cylinder or shell or matte and the outer lock core (reliable, stable and comparatively elasticity is moderate) (elastic component does not compress, all can stretch, and helical form, polyline shaped all can be connected an elastic component.Preferred helical form compression, polyline shaped compression or drawing), when closing lockset, elastic component promotes outer lock core and resets.So, flexible resistance when rotating internal cylinder makes picking lock have certain difficulty, is equivalent to increase a mechanical force.Elastic component can be installed in shell or/and in the groove of interior (outward) plug face.The structure of this kind elastic component also can be applicable to existing all kinds of lockset, be connected an elastic component (elastic component is installed in the groove of lock core and housing contacts face) between lock core and the shell, need certain mechanical force when making key rotation lock core, can play certain antitheft effect.

Among Fig. 1, the outer jump ring 6 of dotted line, the outer jump ring 8 in top are covered, so with dashed lines.

Among Fig. 2, because key is flat-shaped, so outer lock core is or/and the outer jump ring on the lock core of outer top or/and outer top jump ring is respectively the straight line distribution, comes corresponding with the stuck point on key one side or the dual-side.The outer jump ring 6 of dotted line, the outer jump ring 8 in top are covered, so with dashed lines.

Among Fig. 3, the interior stuck point 15 on the key 9, outer stuck point 16. push up interior stuck point 17, the outer stuck point 18 in top is corresponding with the structure among Fig. 1 respectively.The outer stuck point 16 of dotted line, the outer stuck point 18 in top are covered, so with dashed lines.

Among Fig. 4, the interior stuck point 15 on the key 9, outer stuck point 16. push up interior stuck point 17, the outer stuck point 18 in top is corresponding with the structure among Fig. 2 respectively.

Fig. 5 is cross section circle, ellipse, than the outer lock core 4 of regular polygon key correspondence, the schematic cross-section of outer jump ring 6.

Fig. 6 is cross section circle, ellipse, than the outer lock core 4 of regular polygon key correspondence, the schematic cross-section of outer jump ring 6.

Fig. 7 be oval, than the outer lock core 4 of regular polygon key correspondence, the schematic cross-section of outer jump ring 6.

Fig. 8 is the outer lock core 4 of flat-shaped key correspondence, the schematic cross-section of outer jump ring 6.

Among Fig. 9, internal cylinder 2 is overlapping with outer lock core 4 substantially, the interior jump ring 5 of internal cylinder is arranged in a side of internal cylinder longitudinal section (as Figure 10, right half of), it is upward in alignment that the outer jump ring of outer lock core 6 is positioned at outer lock core (right substantially half of), can contact with a side or the dual-side stuck point of key (flat-shaped).If key is circular or oval or than regular polygon, then outer jump ring 6 can spread all over the right half of of whole outer lock core.It is good that interior jump ring on the internal cylinder becomes horizon substantially with interior jump ring among Fig. 9.Outer jump ring and interior jump ring on the outer lock core stagger, and the hollow out of interior jump ring correspondence is arranged on the outer lock core.So, lock core needn't be divided at least two sections, as long as internal cylinder, outer lock core are arranged.In this kind structure, can adopt connected mode or card structure mutually between aforementioned outer lock core and internal cylinder or the shell.Also can adopt the card structure mutually of key and internal cylinder, outer lock core.

Outer lock core can extend to the key port place always in the middle of substantially, but prerequisite is not influence internal cylinder to rotate, jump ring work in not influencing, and corresponding site can hollow out.

The cross section of key any section can be arbitrary shape: rule such as L shape, zigzag or irregularly shaped, the lock core of corresponding position is suitable with it.

The jump ring of each stuck point correspondence can become arbitrarily angled with key and contact.

Also shouldn't matte.

On the matte part hollow out can be arranged, but the outer jump ring 6 under the matte is covered to good still.

The whole rotational angle of key is greater than 0 degree, smaller or equal to 360 degree.

There is an elasticity screens (when the active force of key arrives to a certain degree greatly, elasticity screens distortion) outer lock core and key contact position, and the correspondence position of key has secondary screens.Key is stressed, and secondary screens touches screens, screens distortion, secondary screens and screens card group (can there be a fixedly screens on the screens next door, secondary screens is stuck between two screens, thereby secondary screens drives the forward and reverse rotation of outer lock core).Certainly outer lock core can only the rotational fixation angle, so shouldn't in phase card structure between the outer lock core.Also can remove the elastic component (it is also beneficial to keep elastic component certainly) that outer lock core is connected with other positions.

Internal cylinder is 1, outer lock core can be more than 1 or 1, between any two outer lock cores certain rotational angle is arranged, corresponding stuck point is docked with jump ring, the structure (one, two, three outer lock cores are promptly arranged, and correspondence has one group, two groups, three groups corresponding outer jump rings on the key) thereby solid line two-stage, three grades even level Four are unblanked.Phase card structure (connecting elastic component between outer lock core and shell or internal cylinder or matte or the adjacent outer lock core) is arranged between the outer lock core or corresponding (as described in epimere) card structure is mutually arranged between key and outer lock core.

The burble point of lockset is the latching structure more than 1 or 1, and the outer lock core that rotates drives a latching structure at last, and perhaps internal cylinder is managed a latching structure, latching structure of each outer lock core management.Latching structure is the structure that lockset shell and retainer tie point place are blocked mutually.Can there be one or more latching structure at tie point place of lockset shell and retainer.

The area that key is corresponding with matte slightly concaves, and rice Na and the summary corresponding with key of corresponding other positions of (top) lock core section at least outward is good to evagination.Help outer jump ring and dock, help matte and rotate with outer stuck point.

Above-mentioned all is to adopt more old-fashioned stuck point, the structure of jump ring, and use certainly also can combine with lock core structure, the Key structure of existing various locks.As long as lock core is divided into two parts (at least two sections or at least two) at least, after internal cylinder turned an angle, the structure that drives the outer lock core rotation all could.Also but the keyhole end is an outer lock core, and the front end place is an internal cylinder.

The lockset of existing lock core idle running, the concave surface or the dual-side of its key have stuck point, and dual-side or concave surface and convex surface do not have stuck point.Can add one deck outer lock core in this internal cylinder existing lock core as internal cylinder, outer jump ring is arranged on the outer lock core.The concave surface of key or/and dual-side or/and convex surface is provided with corresponding stuck point (stuck point with at random for good), jump ring on the outer lock core the back side of key initial bit (be equivalent to the key convex surface or/and concave surface or/and dual-side increases stuck point) or miss certain angle (be equivalent to behind the key turns certain angle back side stuck point with outside jump ring dock), be good to miss certain angle.The angle (if between internal cylinder and the shell active force structure is arranged, as jump ring, then the corresponding site of outer lock core is reserved hollow out) that this certain angle is normally unblanked required rotation less than key.Be connected with elastic component between outer lock core and shell or the internal cylinder, perhaps control mutually with screens, secondary screens between outer lock core and the key.This kind structure is equivalent to there is not matte, because internal cylinder itself promptly plays the effect of matte.Outer lock core can be thought one-level outer lock core (convex surface of corresponding key or concave surface or a side), secondary outer lock core (concave surface of corresponding key or convex surface or a side).The internal cylinder that this segment table is stated, outer lock core be the position relation not necessarily, and just internal cylinder is moving earlier, the relation of moving behind the outer lock core.The interior outer lock core of explaining previously also means this in fact.Being based on the succession of being started by key, is not must be interior or outside.

The cross section be in circular arc or circle or ellipse or polygonal concave surface of calibration or the cross section mouth corresponding lock core can be the shell at keyhole front end face place to keyhole to stretching out straight section, this straight section is as the part of shell, can be provided with the lock core that can rotate above, jump ring is arranged on the lock core, and this jump ring is having corresponding stuck point on the key.

In the various structures, the secondary screens on the key and the screens of outer lock core cooperatively interact, but are good with it at random in key, position on outer lock core.So increase the difficulty of picking lock.
