Abstract
The invention discloses a kind of lock core structure of anti-technical lock set, comprise lock core and be positioned at the inner pressed locking side column of locking side column groove on the lock core, the both sides of stretching into the end in the lock body groove on the described inner pressed locking side column are provided with step, also be provided with anti-inclination gathering sill on the inner pressed locking side column, be fixed with the guide pad that cooperates with anti-inclination gathering sill on the inner pressed locking side column on the lock core.When with the non-matching key lock set, when with the instrument lock set, even the tartar and the approaching situation of lock core original key of unlocking tool occur, as long as rotational lock core, step on the inner pressed locking side column all can be stuck in the surface of lock core, can not tilt simultaneously yet, make the inner pressed locking side column not return in the lock core.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.
Description
Technical field
The invention belongs to mechanical lock, relate to a kind of lock core structure of anti-technical lock set.
Background technology
The ZL99115581.5 patent documentation discloses a kind of inner pressed locking side column lock core structure, see Fig. 1, Fig. 2, comprise lock body 1, lock core 2, be positioned at the inner pressed locking side column 3 of locking side column groove on the lock core, one end of inner pressed locking side column 3 stretches in the lock body groove 6, and it is to cooperate to come control lock to open and close by inner pressed locking side column 3 with the pellet shot from a slingshot 4 of lock core 2 interior band V-shaped grooves 5.Although this lock has the characteristics of theftproof and anti-skilled unlocking preferably.But, also come with some shortcomings, when for example skilled unlocking is with the instrument lock set, 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 6 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 5 of pellet shot from a slingshot 4, its other end (seeing the left side among Fig. 1) has only fraction 31 to be positioned at the groove 6 of lock body 1 very much, at this moment only need by cover lock tool 7 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
Purpose of the present invention is intended to overcome the deficiency of above-mentioned technology, and the lock core structure of the higher anti-technical lock set of a kind of safety is provided.
The technical scheme that realizes the object of the invention is: the lock core structure of anti-technical lock set, comprise lock core and be positioned at the inner pressed locking side column of locking side column groove on the lock core, the both sides of stretching into the end in the lock body groove on the described inner pressed locking side column are provided with step, also be provided with anti-inclination gathering sill on the inner pressed locking side column, be 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
The lock core structure of anti-technical lock set of the present invention as shown in Figure 3, Figure 4, comprise lock body 1, lock core 2 is housed in the lock body 1, the inner pressed locking side column 3 that is provided with in the locking side column groove of lock core 2 matches with the pellet shot from a slingshot 4 of band V-shaped groove 5, and the both sides of stretching into the end in lock body 1 groove on the inner pressed locking side column 3 are provided with step 10; Also be provided with anti-inclination gathering sill 8 on the inner pressed locking side column 3, be fixed with the guide pad 9 that cooperates with anti-inclination gathering sill 8 on the inner pressed locking side column on the lock core 2.
As shown in Figure 5, when skilled unlocking is used instrument 7 lock sets, as long as anticlockwise rotational lock core 2, step 10 on the inner pressed locking side column right side will be stuck on the outer wall of lock core 2, the inner pressed locking side column can not be returned in the lock core 2, and lock can't be opened, and vice versa.
Even if occur the tartar of the tartar of non-matching key simultaneously near the lock core original key, under the position-limiting action of the guide pad on the lock core 9, inner pressed locking side column 3 can not tilt yet, and it is positioned at the motionless lockup state that is in of the whole maintenance of an end of lock body 1 groove, and lock can't be opened.
As shown in Figure 6, when unblanking with original key 11, inner pressed locking side column 3 moves downward perpendicular to pellet shot from a slingshot 4 levels along the guide pad on the lock core 29, cooperates with the V-shaped groove 5 of pellet shot from a slingshot 4, withdraws from entering lock core 2 in the groove 6 of lock body 1, at this moment lock can be opened.
Claims (1)
1, a kind of lock core structure of anti-technical lock set, comprise lock core and be positioned at the inner pressed locking side column of locking side column groove on the lock core, it is characterized in that the both sides of stretching into the end in the lock body groove on the described inner pressed locking side column are provided with step, also be provided with anti-inclination gathering sill on the inner pressed locking side column, be fixed with the guide pad that cooperates with anti-inclination gathering sill on the inner pressed locking side column on the lock core.
