Description
Technical field
The invention belongs to lockset, be specifically related to a kind of ball lock head of anti-skilled unlocking.
Background technology
In the existing lockset a kind of ball lock head is arranged, as shown in Figure 1 and Figure 2, comprise the lock core 2 in lock body 1 and the lock body, lock core 2 upper edges are axially arranged with some pellet shot from a slingshot 5 and pellet shot from a slingshot back-moving springs that are provided with v-depression 7, lock core 2 is provided with the locking side column groove, be provided with the inner pressed locking side column 3 that can match in the locking side column groove with v-depression 7 on the pellet shot from a slingshot 5, on lock core 2, be provided with block 9, between block 9 and inner pressed locking side column 3, be provided with locking side column back-moving spring 10, lock core 2 afterbodys are provided with locking bar 13, on the lock body 1 with the corresponding groove 4 that is provided with of locking side column groove on the lock core 2; On lock body 1, be provided with the helicla flute 12 of perforation, be provided with the pin 11 that matches with helicla flute 12 on the lock body on the lock core 2.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 conversion tartar, 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 3 return lock core 2 in the groove 4 of lock body 1, lock tube is opened once being; The 2nd, inner pressed locking side column 3 meeting run-off the straight phenomenons, one head (seeing the right among Fig. 1) fits in the lock core 2 with the v-depression 7 of pellet shot from a slingshot 5, its other end (seeing the left side among Fig. 1) has only fraction 14 to be positioned at the groove 4 of lock body 1 very much, at this moment only need by cover lock tool 6 firmly rotational lock core 2 also lock may be opened, no matter the sort of situation all stays hidden danger aspect safety.
Summary of the invention
The objective of the invention is at the problems referred to above, the ball 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 ball lock head of anti-skilled unlocking of the present invention, comprise the lock core in lock body and the lock body, the lock core upper edge is axially arranged with some pellet shot from a slingshot and pellet shot from a slingshot back-moving springs that are provided with v-depression, lock core is provided with the locking side column groove, be provided with the inner pressed locking side column that can match in the locking side column groove with v-depression on the pellet shot from a slingshot, 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; 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.
The present invention is provided with step because the inner pressed locking side column is positioned at the sidepiece of an end of lock body groove, 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, 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 invention will be further described below in conjunction with accompanying drawing.

The specific embodiment
As Fig. 3, Fig. 4, shown in Figure 7, the ball lock head of anti-skilled unlocking of the present invention, comprise the lock core 2 in lock body 1 and the lock body, lock core 2 upper edges are axially arranged with some pellet shot from a slingshot 5 and pellet shot from a slingshot back-moving springs 8 that are provided with v-depression 7, lock core 2 is provided with the locking side column groove, be provided with the inner pressed locking side column 3 that can match in the locking side column groove with v-depression 7 on the pellet shot from a slingshot 5, on lock core 2, be provided with block 9, between block 9 and inner pressed locking side column 3, be provided with locking side column back-moving spring 10, lock core 2 afterbodys are provided with locking bar 13, on the lock body 1 with the corresponding groove 4 that is provided with of locking side column groove on the lock core 2; On lock body 1, be provided with the helicla flute 12 of perforation, be provided with the pin 11 that matches with helicla flute 12 on the lock body on the lock core 2; The both sides of stretching into the end in the groove 4 on the lock body 1 on the described inner pressed locking side column 3 are provided with step 15, also be provided with anti-inclination gathering sill 17 on the inner pressed locking side column 3, be fixed with the guide pad 16 that cooperates with anti-inclination gathering sill 17 on the inner pressed locking side column on the lock core 2.
Operating principle
See Fig. 5, Fig. 6, after inserting key 18, locking side column 3 returns on the lock core 2 match with v-depression 7 on the pellet shot from a slingshot 5, lock core 2 can rotate relative to lock body 1, when with key 6 (referring to Fig. 8) during rotational lock core 2 in the direction of arrows, helicla flute 12 motions of pin 11 on the lock core 2 on lock body 1 make lock core 2 move right along axis simultaneously, and the locking bar 13 that is located at control dead bolt on the lock core 2 returns in the lock body 1.When locking, with key backward rotation lock core, locking bar 13 is reached can be spacing with dead bolt (drawing) outside the lock body 1.
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 9, step 15 on the inner pressed locking side column 3 all can be stuck in the surface of lock core 2, makes inner pressed locking side column 3 can not return in the lock core 2, can't unblank; Again because inner pressed locking side column 3 is provided with anti-inclination gathering sill 17 match with guide pad 16 on the lock core 2 (referring to Fig. 4), make inner pressed locking side column 3 to move up and down perpendicular to pellet shot from a slingshot 5 levels, when with the non-matching key lock set, even if the tartar of the tartar of non-matching key 6 occur near the lock core original key, inner pressed locking side column 3 can not tilt yet, its upper end all is positioned at the groove of lock body, can't unblank.
