The specific embodiment

Embodiment 1

Referring to Fig. 1,2,3, the present invention includes lock core 1, the overcoat 2 of lock core 1, lock core 1 is realized conjuncted or split with overcoat 2 by the billiards structure of prior art, be illustrated as pellet shot from a slingshot 3 and following pellet shot from a slingshot 4 realization lock cores 1 and overcoat 2 and when inserting key (key is not all drawn in key and the lock core 1), realize split, thereby allow both relative slips, when extracting key, last pellet shot from a slingshot 3 and following pellet shot from a slingshot 4 changing position under the effect of spring 5, make lock core 1 and overcoat 2 interconnected body mutually, thereby lock core 1 can not slide again.Figure 1 shows that when from keyhole 6, extracting key spring 7 promotes lock core 1 and is repositioned to the position-limited edge of overcoat 2 along (or other limit method makes lock core 1 can not break away from overcoat 2).Latch bolt block 8 stretches out lock overcoat 2 under the promotion of spring 9, realize lock out action.When key enters lock core 1 fully by keyhole 6, pellet shot from a

slingshot

3,4 is in the position that allows lock core 1 and overcoat 2 to slide, move ahead by promoting key drive lock core 1, corresponding V-type groove on the grand body pushing of the wedge type of the lock core 1 end latch bolt block 8, latch bolt block 8 is moved to right, thereby realize that dead bolt 8 changes the breakdown action of tongue type.Leave the notch of mounting spring 9 and the opening that dead bolt 8 passes through on the overcoat 2.Need to prove that billiards structure in the present embodiment is as just signal, existing billiards structure technology, as a word, cross pellet shot from a slingshot or blade type pellet shot from a slingshot or magnetic bullet technology or side column lock-in techniques (seeing Chinese patent 99233345.8 for details), as shown in figure 10, wait and may be used in this lock head structure.Among Figure 10, when key inserted lock core 1 fully, side column 10 entered in the corresponding hole of overcoat 2 fully, and the part of extracting key side column 10 can fall in the lock core 1.

Lock core shown in above-mentioned 1 is the square cross section, can also be circular cross-section certainly, or other shaped cross structure.As adopt circular cross-section, should set up one between lock core 1 and the overcoat 2 and limit both and relatively rotate spacing slip pin, as existing pressing lock header structure.By the motion in the grand body insertion of the wedge type V-type groove, realize that the longitudinal sliding motion of lock core 1 is converted into the transverse movement of dead bolt 8 in the present embodiment.Other method also can adopt, and as gear drive etc., belongs to known technology, no longer diagram.

Embodiment 2

Referring to Fig. 4, identical with embodiment 1 effect, difference is between the end of lock core 1 and the dead bolt 8 an indirect slide mass 11 to be set.When lock core 1 moved ahead, lock core 1 promoted indirect slide mass 11 and contacts with dead bolt 8, realizes above-mentioned unlatching and lock function.The advantage of present embodiment is to use high-abrasive material to make slide mass 11 and dead bolt 8 especially.

Embodiment 3

Referring to Fig. 5,6, present embodiment and embodiment 1 are mutually roughly the same, difference only is that spring 9 is installed in an other end of dead bolt 8 (structure that dead bolt 8 connects spring 9 is not drawn), the grand body of wedge type by lock core 1 end when with the shank of the key or hand propelled lock core 1 inserts the V-type groove on the dead bolt 8, dead bolt 8 is moved to left realize the locking action of tapered end, when inserting key, lock core 1 can slide relatively with overcoat 2, lock core 1 is outwards retired under the effect of spring 7, at this moment, spring 9 promotes dead bolt 8 and returns in the overcoat 2, realizes the unlatching of tapered end.
