The utility model content

The purpose of this utility model is at above-mentioned situation, and a kind of blade marble lockset that can improve size of key and reduce the improved employing milling teeth groove key of mutual opening rate is provided.

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, on the lock body with the corresponding groove that is provided with of locking side column groove 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.

The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

Embodiment 1

See Fig. 1, Fig. 2, 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, 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.

See Fig. 5 with the key that the utility model tapered end is supporting, comprise spoon sheet 18, mill teeth groove 22 and interior mill teeth groove 19 outside the sidepiece of the one side of spoon sheet 18 and middle part are respectively equipped with, a sidewall 20 of the sidewall 21 of mill teeth groove and interior mill teeth groove is provided with tartar outside.
