The make progress aperture of marble hole 9-2 of described radially lower marble hole 11-5 and the footpath on tapered end 9 is identical.
As shown in Figure 2 and Figure 3, comprise the shank of the key 23-1, key ring 23-2 and key cylinder 23-4, key cylinder 23-4 is enclosed within key ring 23-2, and the shank of the key 23-1 is connected with key ring 23-2; Also comprise toothed segment 23-5, the front end of key cylinder 23-4 is provided with toothed segment 23-5 vertically, key cylinder 23-4 is inserted in the tapered end 9 of described lock core body, toothed segment 23-5 coordinates with the downward pellet 26 in footpath of described lock core body, on key ring 23-2 lateral surface, axially have projection groove, key cylinder 23-4 rear end is provided with key projection 23-3, and key projection 23-3 is embedded in the projection groove of key ring 23-2 and moves axially along key ring 23-2.
Key cylinder 23-4 front end face has the hole coordinating with the rear lock core body 11-6 of described lock core body, and key cylinder 23-4 front end face is uniformly distributed along the circumference and has cannelure, has the key pins groove coordinating with the axial cylinder 29 of described lock core body on key cylinder 23-4 centre bore.
Described key projection 23-3 mobile shift length in the projection groove of key ring 23-2 is greater than the length of toothed segment 23-5.
In described lock body 8, inclined lock tongue pole 22 end faces are provided with left electrode 21, on plate 20, are provided with right electrode 18 with the end face of the corresponding side of inclined lock tongue pole 22; When oblique dead bolt 1 stretches out lock body 8, left electrode 21 does not contact with right electrode 18; When oblique dead bolt 1 does not stretch out lock body 8, left electrode 21 touches right electrode 18;
In described lock core body, make progress any two footpaths in marble hole 9-2, one row footpath make progress on downward pellet 26 end faces in footpath of marble hole 9-2 and are respectively provided with pellet electrode, toothed segment 23-5 is provided with two interconnective toothed segment electrodes, and two toothed segment electrodes coordinate with pellet electrode separately respectively; Two toothed segment electrodes are by the connection that is conducted of the metallic conductor of key own.
The downward pellet 26 in described footpath, footpath make progress pellet 25 for common spring, and by footpath, pellet 25,26 and axial cylinder 29 form lock core marble up and down.
Lock core structure of the present invention has adopted the structure of brand-new axial and radial arrangement pellet, is about to common spring lock and the combination of Novel double offset ring lock, improves lock core security performance.By the architecture advances of the structure of axial cylinder and general deep-slotted chip breaker, be:
Square section and the cylindrical section at two ends of axial cylinder 29 in the middle of comprising, the deep-slotted chip breaker of snap ring changes square groove and axial cylinder 29 square section into and coordinates.Like this, stopped the possibility that rough power is unblanked, and radial and axially all arranged that pellet has increased the difficulty of illegally unblanking.In the outer cylinder of lock core 11, there is a lock core boss to arrange radially lower marble hole for placing described one, radially lower marble hole and footpath on the tapered end marble hole pore size that makes progress is identical, position matches, in order to make lock core marble radial position, fix, at front lock core body front end, have an annular groove, annular groove communicates with marble hole radially.
And have in the key coordinating with it, key cylinder front end have toothed segment can with lock core radially pellet coordinate, toothed segment is wherein respectively installed an electrode between one section and the downward pellet in corresponding footpath, key cylinder front end has cylindrical hole and coordinates with lock core column, rear end has can be for the projection of push-and-pull key cylinder, projection is embedded in the projection groove of the front and back closure that key ring opens, the maximum displacement that projection advances is greater than described toothed segment length, when projection moves to foremost, the stuck point of its lower end, both sides can snap in little draw-in groove, so key can only be pinned projection with hand after stretching out, just can make it retreat.
The specific embodiment of the invention course of work is as follows:
During normality, door lock is locked, when wanting to open the door, pin key projection 23-3, key cylinder 23-3 is released, at this moment key 23 is inserted to lock core 11, the toothed segment 23-5 on key 23 coordinates with the downward pellet 26 in footpath, the footpath that pellet 25 is pushed in tapered end 9 completely that makes progress, footpath is made progress in marble hole 9-2, remove the radially locking of pellet; The front end cylinder groove of key cylinder 23-4 and groove coordinate with rear lock core body 11-6 and axial cylinder 29, driving axial pellet 29 moves vertically, when square section of breach of axial cylinder 29 and snap ring 28 are positioned at same plane, can remove the locking of axial cylinder, thereby by lock core 11 releases, lock core 11 can rotate with key 23, rotate key 23, lock core 11 rotates, open the door, extract key 23, the possibility that in lock core 11, the use of the two-way billiards structure of radial-axial is opened the door illegal instrument lowers greatly, and theftproof increases.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change that the present invention is made, all fall into protection scope of the present invention.
