Abstract

The utility model discloses a blade spring lock head for preventing technical unlocking, which comprises a lock body and a lock core, wherein the lock core is provided with an integral blade groove, a plurality of two blade springs and movable spacers which are a group are arranged in the blade groove, and the lock core is provided with an internal pressure type locking side post which is matched with V-shaped grooves on the blade springs and the movable spacers; the lock is characterized in that steps are arranged on two sides of one end of the internal pressure type locking side column, which extends into the upper groove of the lock body, an anti-inclination guide groove is further arranged on the internal pressure type locking side column, and a guide block matched with the anti-inclination guide groove on the internal pressure type locking side column is fixed on the lock core. Because the step is arranged on the internal pressure type locking side column, and the anti-inclination guide groove is arranged to be matched with the guide block on the lock core, the technical unlocking can be ensured by using an unavailable tool.

Description

A kind of blade spring lock head of anti-skilled unlocking

Technical field

The invention belongs to lockset, be specifically related to a kind of blade spring lock head of anti-skilled unlocking.

Background technology

In the prior art, a kind of blade locking head is arranged, as shown in Figure 1 to Figure 3, comprise lock body 2 and lock core 1, lock core 1 is provided with integral blade groove 7, placing some two in blade groove 7 is one group blade marble 5 and movable partition 6, and lock core 1 is provided with the inner pressed locking side column 4 that matches with v-

depression

51,61 on blade marble 5 and the movable partition 6.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 the tartar of unlocking tool 8, the tartar of unlocking tool is arranged as 1,2,3,5,4,6), may occur that: as long as the left-right rotation lock core can make inner pressed locking side column 4 return lock core 1 in the groove 3 of lock body 2, lock tube is opened once being; The 2nd, inner pressed locking side column 4 meeting run-off the straight phenomenons, one head (seeing the right among Fig. 1) fits in the lock core 1 with the V-shaped groove 51 of blade marble 5, its other end (seeing the left side among Fig. 1) has only fraction 41 to be positioned at the groove 3 of lock body 2 very much, at this moment only need by cover lock tool 8 firmly rotational lock core 1 also lock may be opened, no matter the sort of situation all stays hidden danger aspect safety.

Summary of the invention

Purpose of the present invention is intended to overcome the deficiency of above-mentioned technology, and the blade spring lock head of the higher anti-skilled unlocking of a kind of safety is provided.

The technical scheme that realizes the object of the invention is: the blade spring lock head of anti-skilled unlocking, comprise lock body and lock core, lock core is provided with the integral blade groove, placing some two in blade groove is one group blade marble and movable partition, and lock core is provided with the inner pressed locking side column that matches with v-depression on blade marble and the movable partition; 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 invention 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.

Further specify technical scheme of the present invention below in conjunction with accompanying drawing.

The specific embodiment

Extremely shown in Figure 7 as Fig. 4, the present invention includes lock body 2 and lock core 1, lock core 1 is provided with integral blade groove 7, placing some two in blade groove 7 is one group blade marble 5 and movable partition 6, movable partition 6 is between each group blade marble 5, a shared return spring 9 between every group of blade marble 5 wherein is respectively equipped with corresponding keyhole 13 on blade marble 5 and the movable partition 6.Fig. 5 shows the blade groove 7 that removes on blade marble 5 and movable partition 6 rear lock cores; Lock core 1 is provided with the inner pressed locking side column 4 that matches with v-

depression

51,61 on blade marble 5 and the movable partition 6 (referring to Fig. 3); The both sides of stretching into the end in the groove 3 on the lock body 2 on the described inner pressed locking side column 4 are provided with step 10, also be provided with anti-inclination gathering sill 12 on the inner pressed locking side column 4, be fixed with the guide pad 11 that cooperates with anti-inclination gathering sill 12 on the inner pressed locking side column 4 on the lock core 1.

When unblanking (referring to Fig. 8), key 14 inserts from the keyhole 13 on blade marble 5 and the movable partition 6, make v-depression 51 alignment on the blade marble 5, inner pressed locking side column 4 matches with v-

depression

51,61 on blade marble 5 and the movable partition 6 and enters in the lock core 1, and rotational lock core gets final product.

If use the unlocking tool lock set, even if occur and the approaching tartar of original key, as long as rotational lock core, as shown in Figure 9, the notch edge of the inner pressed locking side column groove on the lock core will enter in the step 10 on the inner pressed locking side column 4, inner pressed locking side column 4 is stopped can not enter in the lock core; Simultaneously the guide pad 11 of inner pressed locking side column 4 on lock core is spacing down, can run-off the straight, and also can make an end of inner pressed locking side column 4 all be positioned at groove 3 (referring to Fig. 6) on the lock body 2.The double action of said structure can be guaranteed can't the tool using skilled unlocking.
