Realize that the purpose of this utility model technical scheme is: the blade marble lockset of improved employing milling teeth groove key of the present utility model comprises tapered end and supporting key thereof; Described tapered end comprises the lock core in lock body, the lock body, it is one group blade marble group by two blade marbles that the lock core upper edge is axially arranged with some, be arranged in the middle part of blade marble group one blade marble of homonymy and the end of another blade marble and be respectively equipped with the projection that extend into keyhole, the opposite side of each blade marble is provided with v-depression, and corresponding each blade marble is provided with the blade marble back-moving spring respectively on the preceding lock core; Lock core is provided with the locking side column groove, be provided with the locking side column that can match in the locking side column groove with v-depression on the blade, on lock core, be provided with block, between block and locking side column, be provided with locking side column Flexible Reset device, the lock core afterbody is provided with locking bar, on the lock body with the corresponding groove that is provided with of locking side column groove on the lock core; On lock body, be provided with the helicla flute of perforation, be provided with the projecting part that matches with helicla flute on the lock body on the lock core;
Described and the supporting key case spatula sheet of tapered end, mill teeth groove and interior mill teeth groove outside the sidepiece of the one side of spoon sheet and middle part are respectively equipped with are provided with tartar on the sidewall of the sidewall of mill teeth groove and interior mill teeth groove outside one.
Described locking side column Flexible Reset device also can correspondence be provided with the identical magnetic patch of polarity for spring is set between lock core block and locking side column between lock core block and locking side column.
Characteristics of the present utility model are to use the inside and outside milling teeth groove key different with the normal key structure, because the key that is adopted is provided with outer mill teeth groove and interior mill teeth groove simultaneously, improved the size of key of lockset and reduced mutual opening rate, made lockset that better theftproof performance be arranged.Because lock core is provided with the projecting part that matches with helicla flute on the lock body, when inserting key unlocking, projecting part in the process of rotational lock core on the lock core will move by helicla flute on lock body, make lock core when lock body is made circular motion relatively, also do axially-movable, only need the backward rotation lock core during locking.The utility model tapered end is exactly to utilize this axially-movable of lock core to reach from the purpose of axial control dead bolt, therefore can be used for the lockset of this occasion.
The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment
Embodiment 1
See Fig. 1, Fig. 2, Fig. 5, tapered end of the present utility model comprises the lock core 2 in lock body 1, the lock body 1, and lock core 2 upper edges are axially arranged with some horizontal blade marble holes 11, and blade marble hole 11 communicates with the keyhole 9 that axially is provided with; Be provided with two blade marbles 6,16 that are stacked as a group mutually in each blade marble hole 11, be arranged in the middle part of blade marble group blade marble 16 of homonymy and the end of blade marble 6 and be respectively equipped with the projection 8,10 that extend into keyhole, the opposite side of blade marble 6,16 is respectively equipped with v-depression 7, and the blade marble 6,16 on the lock core 2 in corresponding each group is provided with blade back-moving spring 5,12 relatively respectively; Lock core 2 is provided with locking side column groove 3, be provided with the locking side column 4 that can match in the locking side column groove 3 with v-depression 7 on the blade marble 6,16, on the notch of lock core locking side column groove, be provided with block 14, on block 14 and locking side column 4, be provided with locking side column back-moving spring 15 in the corresponding groove 13 with it, lock core 2 afterbodys are provided with locking bar 19, on the lock body 1 with lock core 2 on the locking side column groove 3 corresponding grooves 17 (referring to Fig. 3) that are provided with, on lock body 1, be provided with the helicla flute 21 of perforation, be provided with the pin 20 that matches with helicla flute 21 on the lock body on the lock core 2.
