The utility model relates to a kind of safety lockset, specifically a kind of lock core of theftproof lock, comprise lock core, lock core end face center is provided with mandrel, lock core circumferential surface offers radial through lockhole near bottom position, lockhole end face centre position is extended downwards lockhole boss, described lockhole boss bottom surface is provided with two projections be parallel to each other, a groove is formed respectively between the inwall that lockhole boss two side is corresponding with lockhole, lock core end face is provided with two row's shell holes, each shell hole is all connected to downward-extension with groove, lock core bottom surface is provided with movable breach.The utility model product structure is simple, reasonable, protruding by setting up two rows on the lockhole boss of lock core, increase frictional force when lawless person is unblanked by hard paper on the one hand, when multilayer hard paper is unblanked, one deck hard paper directly contacted with projection due to frictional force larger, akinesia, upper strata scraps of paper action does not affect inner pellet, thus cannot unblank.
Description
Technical field
The utility model relates to a kind of safety lockset, specifically a kind of lock core of theftproof lock.
Background technology
In the every field of daily life, lockset is all the necessity ensureing property safety, and its safe coefficient is extremely important, and present lockset is of a great variety, has electronic lock, coded lock and our the most frequently used cylinder lock etc.Electronic lock and coded lock price costly, are difficult to popularize on a large scale, and the safety of these two kinds locks simultaneously also needs to be checked further; Cylinder lock is lockset comparatively conventional at present, popularizing also due to cylinder lock, some attempt burglaries unprincipled fellow usually ponder cylinder lock without key unlocking skill and technique, according to the conclusion of survey, cylinder lock is often unblanked by with hard paper, and which floor they are by after being converted into by hard paper, inserts in lock by the hard paper after folding along lockhole gap, the movement of the pellet in shell hole is driven by the movement of hard paper, and the object of being unblanked by the mobile realization of pellet.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of lock core of theftproof lock, adopts this lock core significantly can improve the security performance of theftproof lock.
According to the technical solution of the utility model: a kind of lock core of theftproof lock, it is characterized in that: comprise lock core, described lock core end face center is provided with mandrel, lock core circumferential surface offers radial through lockhole near bottom position, lockhole end face centre position is extended downwards lockhole boss, described lockhole boss bottom surface is provided with two projections be parallel to each other, a groove is formed respectively between the inwall that lockhole boss two side is corresponding with lockhole, lock core end face is provided with two row's shell holes, each shell hole is all connected to downward-extension with groove, lock core bottom surface is provided with movable breach.
As further improvement of the utility model, be threaded connection mode and fix between described mandrel and lock core, mandrel adopts stainless steel material to make.
As further improvement of the utility model, described projection is provided with the twill for increasing frictional force.
As further improvement of the utility model, the shell hole number often arranging shell hole is three.
Technique effect of the present utility model is: the utility model product structure is simple, reasonable, protruding by setting up two rows on the lockhole boss of lock core, increase frictional force when lawless person is unblanked by hard paper on the one hand, when multilayer hard paper is unblanked, one deck hard paper directly contacted with projection due to frictional force comparatively large, akinesia, upper strata scraps of paper action does not affect inner pellet, thus cannot unblank, the projection of simultaneously setting up also effectively reduces the activity space of the scraps of paper; The form that mandrel in addition in the utility model product is threaded connection is fixedly connected with lock core, and processing technology implements comparatively simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 be in Fig. 1 A-A to sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
In Fig. 1 ~ 3, comprise lock core 1, mandrel 2, shell hole 3, lockhole 4, lockhole boss 5, projection 6, movable breach 7, groove 8 etc.
As shown in Figure 1, the utility model is a kind of lock core of theftproof lock, comprise lock core 1, described lock core 1 end face center is provided with mandrel 2, lock core 1 circumferential surface offers radial through lockhole 4 near bottom position, lockhole 4 end face centre position is extended downwards lockhole boss 5, described lockhole boss 5 lower surface is provided with two projections be parallel to each other 6, a groove 8 is formed respectively between the inwall that lockhole boss 5 two side is corresponding with lockhole 4, lock core 1 end face is provided with two row's shell holes 3, each shell hole 3 is all connected to downward-extension with groove 8, lock core 1 bottom surface is provided with movable breach 7.
Be threaded connection mode between described mandrel 2 and lock core 1 to fix.
The twill for increasing frictional force is provided with on described protruding 6.
The shell hole number often arranging shell hole 3 is three.
After the utility model product is installed on anti-theft cylinder lock, because two projections 6 that product is newly established effectively can realize the object of increasing friction force, when lawless person's view multilayer hard paper is illegally unblanked, due to the effect of protruding 6, making with protruding 6 hard papers directly contacted under the effect of frictional force cannot action, thus can not realize the object of unblanking; Adopt the instruments such as electric drill to carry out violence orcible entry to theftproof lock in order to avoid lawless person simultaneously, the mode adopting two parts to be threaded connection between mandrel 2 and lock core 1 is fixed by the utility model product, technique is more prone to manufacture than existing integral structure product, save cost of production, mandrel 2 adopts stainless steel material to make simultaneously, can effectively stop electric drill to run, avoid theftproof lock to be torn down by violence.
