Description

The blade marble lockset of anti-skilled unlocking

Technical field

The utility model belongs to mechanical lock, relates to a kind of blade marble lockset of anti-skilled unlocking.

Background technology

In the existing lockset, a kind of blade spring lock head that utilizes blade marble and inner pressed locking side column to match and lock is arranged.As shown in Figure 1, this tapered end comprises the lock core 2 in the lock body 3, lock body 3, and lock core 2 is provided with the inner pressed locking side column 1 that matches with v-depression on the blade marble 5,10.The problem that this tapered end exists is: if the technical lock set of tool using, (tartar as original key is arranged as 1,2,3,4,5,6 during near the lock core original key when unlocking tool 22 conversion tartars, the tartar of unlocking tool is arranged as 1,2,3,5,4,6), may occur that: as long as left-right rotation lock core 2 can make inner pressed locking side column 1 return lock core 2 in the groove 19 of lock body 3, lock tube is opened once being; The 2nd, inner pressed locking side column 1 meeting run-off the straight phenomenon, one head (seeing the right among Fig. 1) fits in the lock core 2 with the V-shaped groove of blade marble 5,10, its other end (seeing the left side among Fig. 1) has only fraction 23 to be positioned at the groove 19 of lock body very much, at this moment only need by cover lock tool 22 firmly rotational lock core also lock may be opened, no matter the sort of situation all stays hidden danger aspect safety.

The utility model content

The purpose of this utility model is intended to overcome the deficiency of above-mentioned technology, and the blade marble lockset of the higher anti-skilled unlocking of a kind of safety is provided.

The technical scheme that realizes the utility model purpose is: the blade marble lockset of anti-skilled unlocking, comprise the lock core in lock body, the lock body, and lock core is provided with the inner pressed locking side column that matches with v-depression on the blade marble; The both sides of stretching into the end in the groove on the lock body on the described inner pressed locking side column are provided with step, also are provided with anti-inclination gathering sill on the inner pressed locking side column, are being fixed with the guide pad that cooperates with anti-inclination gathering sill on the inner pressed locking side column on the lock core.

Characteristics of the present utility model are, because being positioned at the sidepiece of an end of lock body groove, the inner pressed locking side column is provided with step, when the technical lock set of tool using, even the tartar and the approaching situation of lock core original key of cover lock tool occur, as long as rotational lock core, no matter be clockwise or anticlockwise, the step on the inner pressed locking side column all can be stuck in the surface of lock core, makes the inner pressed locking side column can not return in the lock core; Again because the inner pressed locking side column is provided with anti-inclination gathering sill matches with guide pad on the lock core, make the inner pressed locking side column to move up and down perpendicular to the pellet shot from a slingshot level, when with the non-matching key lock set, even if the tartar of the tartar of non-matching key occur, also can not tilt near the lock core original key.These two kinds of measures can prevent that the situation that instrument lock set or key leave mutually from taking place, and further improves the safety of lock.

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

The specific embodiment

See Fig. 2, Fig. 3, the blade marble lockset of the anti-skilled unlocking of the utility model comprises the lock core 2 in lock body 3, the 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, on the lock body 3 with the corresponding groove 19 (referring to Fig. 4) that is provided with of locking side column groove on the lock core 2, be provided with the inner pressed locking side column 1 that can match in the locking side column groove with v- depression 6,12 on the blade marble 5,10, the both sides of stretching into the end in the lock body groove 19 on the inner pressed locking side column 1 are provided with step 13, also be provided with anti-inclination gathering sill 17 on the inner pressed locking side column, be fixed with the guide pad 16 that cooperates with anti-inclination gathering sill 17 on the inner pressed locking side column 1 on the lock core 2; On the notch of lock core locking side column groove, be provided with block 14, on block 14 and locking side column 1, be provided with inner pressed locking side column back-moving spring 18 with it between the corresponding groove 15.

Operating principle

The utility model tapered end and key 20 supporting uses with interior mill teeth groove 21.As Fig. 4, shown in Figure 5, after key 20 inserts lock core, tartar on the key 20 on the two side of mill teeth groove 21 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 19 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. 2, Fig. 3).

If the technical lock set of tool using is even if the tartar and the lock core original key of cover lock tool are approaching, as long as rotational lock core, as shown in Figure 6, step 13 on the inner pressed locking side column 1 all can be stuck in the surface of lock core 2, makes inner pressed locking side column 1 can not return in the lock core 2, can't unblank; Again because inner pressed locking side column 1 is provided with anti-inclination gathering sill 17 match with guide pad 16 on the lock core 2 (referring to Fig. 3), make inner pressed locking side column 1 to move up and down perpendicular to blade marble 5,10 levels, when with the non-matching key lock set, even if the tartar of the tartar of non-matching key occur near the lock core original key, inner pressed locking side column 1 can not tilt yet, its upper end all is positioned at the groove of lock body, can't unblank.
