Description
Affiliated field
The utility model relates to a kind of anti-theft lock, especially a kind of core of singly unblanking preventing single hook from opening.
Background technology
At present, existing theftproof lock is arrange connector in lock core mostly, connector is provided with groove, key be stretch into connector groove in drive shifting block core to unblank, this lock is easily opened with single hook unlocking tool or steel disc by lawless person, thus enters indoor and commit theft.
Summary of the invention
For above defect, the utility model provides a kind of core of singly unblanking preventing single hook from opening, it can prevent robber from being opened by lock with single material such as unlocking tool or steel disc that hooks effectively outdoor, overcome core of singly unblanking and cause the drawback of anti-theft effect difference because of structural limitation, simple to operate, insurance is reliable, solve singly unblank the at present limitation of core due to self structure and the technical problem of the anti-technical opening poor performance of lock core itself, lawless person cannot open with simple tool, avoid robber easily lock to be opened with single hook outdoor, enter indoor.
For reaching above object, the utility model have employed following technical scheme: a kind of core of singly unblanking preventing single hook from opening, comprise lock housing, lock core, shifting block, structural member, described lock core rear end is provided with groove, described shifting block inner chamber is provided with shifting block core, described shifting block core is special-shaped, be at least two, shifting block core neighboring is provided with a projection or groove, described shifting block core and shifting block inner chamber match, described shifting block core side is provided with retaining part, retaining part is arranged with spring, retaining part one end is stretched in groove, the other end is adjacent with shifting block core, shifting block core opposite side is adjacent with structural member, the other end of structural member is arranged with inner button, spring is provided with between inner button and structural member.
Shifting block core described in the utility model comprises left shifting block core and right shifting block core, and they are symmetricly set on axis; The cross section of described shifting block core is rectangle, polygon, spline shape, profile of tooth etc.; Described left shifting block core or the every rotating 360 degrees of right shifting block core only have a position and shifting block inner chamber to match; Described structural member is connected by connector with inner button.
Have employed above technical scheme, the utility model inserts key or indoor promotion inner button outdoor, by spring promotion retaining part or structural member, left shifting block core or right shifting block core is ejected shifting block, thus reaches the object of unblanking with indoor outdoor.

Fig. 1 is the utility model structural representation.
Fig. 2 is the concavo-convex state diagram that matches of the utility model shifting block and shifting block core.
Detailed description of the invention
According to Fig. 1, the utility model is a kind of prevents single core of singly unblanking hooking unlatching, comprise lock housing 1, lock core 2, shifting block 5, structural member 4, described lock core 2 rear end is provided with groove 9, described shifting block 5 inner chamber is provided with shifting block core 10, described shifting block core 10 is special-shaped, be at least two, shifting block core 10 neighboring is provided with a projection or groove, described shifting block core 10 matches with shifting block 5 inner chamber, described shifting block core 10 side is provided with retaining part 3, retaining part 3 is arranged with spring 6, retaining part 3 one end is stretched in groove 9, the other end is adjacent with shifting block core 10, shifting block core 10 opposite side is adjacent with structural member 4, the other end of structural member 4 is arranged with inner button 8, spring 7 is provided with between inner button 8 and structural member 4.
Shifting block core 10 described in the utility model comprises left shifting block core and right shifting block core, and they are symmetricly set on axis; The cross section of described shifting block core 10 is rectangle, polygon, spline shape, profile of tooth; Described left shifting block core or the every rotating 360 degrees of right shifting block core only have a position and shifting block 5 inner chamber to match; Described structural member 4 is connected by connector with inner button 8.
The utility model detailed description of the invention is as follows: when unblanking outdoor, key is stretched in lock core 2, retaining part 3 is ejected by spring 6, right shifting block core is ejected shifting block 5, rotate key rotating 360 degrees, after the projection of left shifting block core or groove and shifting block 5 inner chamber coincide, move shifting block 5 by left shifting block core ribbon, thus lock is opened; When unblanking indoor, promote inner button 8, structural member 4 is ejected by spring 7, left shifting block core is ejected shifting block 5, rotates inner button 8 rotating 360 degrees, the projection of right shifting block core or groove identical with shifting block 5 inner chamber after, move shifting block 5 by right shifting block core ribbon, thus lock is opened.
