Abstract
The utility model discloses a invisible marble burglarproof lock cylinder, comprising a lock cylinder body and a lock cylinder case, wherein a marble is arranged in a marble hole of the lock cylinder body and a key hole is arranged in the lock cylinder body. The invisible marble burglarproof lock cylinder is characterized in that: the key hole consists of a tail and a head; all the marble holes are arranged side by side under the tail of the key hole; the hole wall of the key hole is provided with blocky interspaces separately at the position near to the marble hole of each lock cylinder body; all the interspaces are separately communicated with the corresponding marble holes thereof. Compared with the prior art, in the utility model, the marble can not be directly exposed in the key hole, human eyes can not observe the marble directly through the key hole; and the deepest depth that the marble is impressed is deeper than the bottom of the key hole, thus preventing technically unlocking and improving the safety performance of the lock. The key hole of the invisible marble burglarproof lock cylinder is small and circular basically, thus preventing unlocking violently by 'master keys'.
Description
Technical field
The utility model relates to a kind of invisible billiards anti-theft lock core.
Background technology
The lock core of the most of cylinder locks known to the public is general main to be made up of plug body, lock core shell, pellet shot from a slingshot, outside the pellet shot from a slingshot of lock core all is exposed to, promptly can see an end of pellet shot from a slingshot in the key hole, the most deep degree that pellet shot from a slingshot is depressed is equal with the bottom in key hole, is easy to by technology unlocking like this.In addition, the key boring ratio is bigger, is easy to be opened by " omnipotent key " violence.
The utility model content
The utility model technical issues that need to address provide a kind of invisible billiards anti-theft lock core, and this kind anti-theft lock can prevent that technology unlocking and violence from unblanking.
The utility model technical solution problem can be by taking following technical scheme:
A kind of invisible billiards anti-theft lock core, comprise plug body, lock core shell, plug body is cylindrical, plug body is positioned at lock core shell, be provided with the pellet shot from a slingshot hole in the lock core shell, be provided with the pellet shot from a slingshot hole in the plug body, the institute pellet shot from a slingshot hole that is provided with is corresponding with the interior set pellet shot from a slingshot hole site of lock core shell in the plug body, be provided with pellet shot from a slingshot in the pellet shot from a slingshot hole in the described plug body, described plug body is provided with the key hole, it is characterized in that: described key hole comprises by afterbody and head, arrange in the afterbody parallel beneath in key hole in described each pellet shot from a slingshot hole, described key hole hole wall is being provided with block space respectively near place, the pellet shot from a slingshot hole of each plug body, and described each space is communicated with corresponding pellet shot from a slingshot hole separately respectively.
The utility model technical solution problem can solve by taking following measure:
The afterbody cross section in described key hole is curved, and the head cross section is rounded, and the cross section in described key hole is similar upset " 6 " shape.The afterbody cross section in described key hole is rectangle, and the head cross section is rounded, and the cross section in described key hole is similar upset " b " shape.Can to make " 6 " also can be " b " shape in the key hole during manufacturing.
The interface area that described each pellet shot from a slingshot hole is communicated with corresponding space is less than the hole area in pellet shot from a slingshot hole.
The part of that end in the close key hole of described pellet shot from a slingshot is exposed in the corresponding space with the interface that corresponding space is communicated with by each pellet shot from a slingshot hole.
The utlity model has following technique effect:
1, the pellet shot from a slingshot of the utility model invisible billiards anti-theft lock core is positioned at the pellet shot from a slingshot hole, and pellet shot from a slingshot also and be separated by between the key hole space is arranged, compared with prior art, pellet shot from a slingshot can directly not expose in the key hole, human eye can not observe directly pellet shot from a slingshot by the key hole, the most deep degree that pellet shot from a slingshot is depressed is deeper than the bottom in key hole, can prevent technology unlocking, has improved the security performance of lockset.
2, the cross section in the key hole of the utility model invisible billiards anti-theft lock core is similar upset " 6 " shape, also can be " b " shape, and the key hole is little, is again circular substantially, can prevent that the violence of " omnipotent key " from unblanking.

The specific embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
As shown in Figures 1 to 4, the invisible billiards anti-theft lock core, comprise plug body 1, lock core shell 2, plug body 1 is cylindrical, and plug body 1 is positioned at lock core shell 2, is provided with the pellet shot from a slingshot hole in the lock core shell 2, be provided with the pellet shot from a slingshot hole in the plug body 1, the institute pellet shot from a slingshot hole that is provided with is corresponding with lock core shell 2 interior set pellet shot from a slingshot hole sites in the plug body 1, and described plug body is provided with pellet shot from a slingshot 3 in the interior pellet shot from a slingshot hole, and described plug body 1 is provided with the key hole.Described key hole is made up of afterbody 4 and head 5, and afterbody 4 is used to insert the key tooth-like part of anything.Afterbody 4 cross sections in described key hole are curved, also can be linears, and head 5 cross sections are rounded, and the cross section in described key hole is similar upset " 6 " shape or " b " shape.Arrange in the afterbody parallel beneath in key hole in described each pellet shot from a slingshot hole, and described key hole hole wall is provided with block space 6 respectively at the place, pellet shot from a slingshot hole near each plug body, and described each space 6 is communicated with corresponding pellet shot from a slingshot hole separately respectively.The interface area that described each pellet shot from a slingshot hole is communicated with corresponding space 6 can prevent like this that less than the hole area in pellet shot from a slingshot hole pellet shot from a slingshot 3 from entering space 6 fully.The part of that end in the close key hole of pellet shot from a slingshot is exposed in the corresponding space 6 with the interface that corresponding space 6 is communicated with by each pellet shot from a slingshot hole.It is the same that other of lock core constructed existing general lock core.The key hole is made up of afterbody and head, and when unblanking, the tooth-like part of anything of key 7 enters the hole by the afterbody in key hole, and the main part of key enters the key hole by the head in key hole.Then, the tooth-like part of anything of key enters separately corresponding shape piece space respectively during rotation, and tooth-like part of anything could contact with pellet shot from a slingshot after entering corresponding separately space respectively, and then promotes pellet shot from a slingshot and move downward, and promptly can open lock.Present embodiment only is that key hole, key, space can be designed to other shape as required for example.
The pellet shot from a slingshot of the utility model invisible billiards anti-theft lock core is positioned at the pellet shot from a slingshot hole, and pellet shot from a slingshot also and be separated by between the key hole space is arranged, compared with prior art, pellet shot from a slingshot can directly not expose in the key hole, human eye can not observe directly pellet shot from a slingshot by the key hole, the most deep degree that pellet shot from a slingshot is depressed is deeper than the bottom in key hole, can prevent technology unlocking, has improved the security performance of lockset.The cross section in the key hole of the utility model invisible billiards anti-theft lock core is similar upset " 6 " shape, and the key hole is little, is again circular substantially, can prevent that the violence of " omnipotent key " from unblanking.
