Abstract

The utility model discloses a wafer tumbler lock comprising a lock cylinder and a matching key. The lock cylinder comprises a lock body, a plug in the lock body, a plurality of through wafer holes are transversely arranged on the plug axially, and the wafer holes are communicated with a key hole which is axially arranged. Each wafer hole is internally equipped with a wafer, and a projection extending into the key hole is arranged close to the middle portion of the identical side of each wafer. The plug is equipped with a locking side-column groove, and a locking side-column matching with V-shaped grooves on the wafers is disposed in the locking side-column groove. The key matching with the lock cylinder comprises a key piece, one side of the key piece is equipped with an inner milled tooth groove, and at least one lateral wall of the inner milled tooth groove is equipped with teeth. The wafer tumbler lock is characterized in that the lock cylinder can be used with a single-face inner milled tooth groove key which is different from the general key structurally, thereby increasing unlocking difficulty and improving anti-thief property of the lock.

Description

Blade marble lockset

Technical field

The utility model belongs to lockset, is specifically related to a kind of blade marble lockset.

Background technology

In the existing lockset, a kind of tapered end that utilizes blade marble to match and lock with locking side column is arranged.This tapered end comprises the lock core in lock body, the lock body, lock core is provided with the locking side column that matches with v-depression on the blade marble, the use that can only match with normal key of blade marble in this tapered end can not match with the key of mill teeth groove in the single face, is therefore limited to aspect theftproof.

The utility model content

The purpose of this utility model be to provide a kind of can with the supporting blade marble lockset of milling teeth groove key in the single face, the difference of its structure can increase the difficulty of unblanking, and improves the theftproof performance of lock.

Realize that the purpose of this utility model technical scheme is: blade marble lockset of the present utility model comprises tapered end and supporting key thereof;

Described tapered end comprises the lock core in the lock body, lock body, and the lock core upper edge is axially arranged with the blade marble hole of some horizontal perforations, and the blade marble hole communicates with the keyhole of axially setting; Be provided with blade marble in each blade marble hole, be provided with the projection that extend in the keyhole near the middle part on the homonymy of each blade marble, the opposite side of each blade marble is provided with v-depression, and corresponding each blade marble is provided with the blade marble return spring respectively on the 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 marble, 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 in the one side of spoon sheet is provided with is provided with tartar at least on a sidewall of interior mill teeth groove.

Blade marble in the described blade marble hole can be a slice or two.

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 keys that tapered end can use mill teeth groove in the single face different with the normal key structure, and it is few to have overcome existing lock head structure, and the deficiency of long easy crack of time has increased the difficulty of unblanking with this, have improved the theftproof performance of lock.

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

The specific embodiment

Embodiment 1

See Fig. 1, Fig. 2, the utility model tapered end comprises the lock core 2 in the lock body 3, lock body 3, and lock core 2 upper edges are axially arranged with the blade marble hole of some horizontal perforations, and the blade marble hole communicates with the keyhole 8 of axially setting; Be provided with two

blade marbles

5,10 that are stacked as a group mutually in each blade marble hole, the homonymy of

blade marble

5,10 is respectively equipped with the

projection

7,9 that extend in the keyhole 8 near the middle part, the opposite side of

blade marble

5,10 is respectively equipped with v-

depression

6,12, and the corresponding blade marble of respectively organizing in the

blade marble

5,10 is provided with blade

marble return spring

4,11 relatively respectively on the lock core 2; Lock core 2 is provided with the locking side column groove, be provided with the locking side column 1 that can match in the locking side column groove with v-

depression

6,12 on the

blade marble

5,10, on the notch of lock core locking side column groove, be provided with block 13, on block 13 and locking side column 1, be provided with locking side column back-moving spring 15 in the corresponding groove 14 with it, on the lock body 3 with the corresponding groove 16 (referring to Fig. 3) that is provided with of locking side column groove on the lock core 2.

See Fig. 5 with milling teeth groove key in the supporting single face of the utility model tapered end, comprise spoon sheet 17, mill teeth groove 18 in the one side of spoon sheet 17 is provided with is provided with tartar on the two side of interior mill teeth groove.

Operating principle

The supporting use of milling teeth groove key in the utility model tapered end and the single face.See Fig. 3, Fig. 4, after spoon sheet 17 inserts lock core, tartar on the spoon sheet 17 on the two side of mill teeth groove 18 acts on the projection on the different blade marbles in each blade marble group respectively, force two blade marbles in each blade marble group to do relative motion respectively, v-depression on all blade marbles is alignd in line, under the return spring effect, one side of locking side column enters in the v-depression of blade marble, return in the lock core in the groove of opposite side from the lock body, at this moment lock core can rotate relative to lock body becomes unlocking condition; After extracting key, blade marble in each blade marble group resets under its return spring effect, v-depression on the blade marble forces locking side column to withdraw from v-depression when resetting, the opposite side of locking side column is stretched in the groove of lock body, by locking side column lock core and lock body are connected as a single entity, at this moment lock core can not rotate relative to lock body becomes locking states (referring to Fig. 1, Fig. 2).

Embodiment 2

As Fig. 7, shown in Figure 8, also can on the notch of the locking side column groove on the lock core, magnetic block 19 be set, with the magnetic block 19 corresponding identical magnetic patch of polarity 20 that are provided with, utilize the repulsive force between magnetic block 19 and the magnetic patch 20 to make the locking side column return in the groove on locking side column.Other structure is all identical with embodiment 1.

Embodiment 3

The utility model tapered end also only the same side in each blade marble hole a slice blade marble is set, the key supporting with it is provided with tartar on the two side of the interior mill teeth groove of spoon sheet.Only utilize the tartar on the sidewall of mill teeth groove in spoon sheet to cooperate during use with blade marble.

Also can be that two blade marbles are set in each blade marble hole, the key supporting with it be provided with tartar (referring to Fig. 6) on a sidewall of the interior mill teeth groove of spoon sheet.Only utilize the tartar on the interior mill teeth groove sidewall of spoon sheet only to cooperate during use with a slice blade marble that each is organized in blade marble.

The purpose of doing like this can increase the disguise of lock construction, because from being difficult to judge the structure of tapered end in appearance, further strengthen antitheft purpose with this.
