Abstract
The utility model discloses a kind of anti-saw lock, comprise there is post head, the lock body of shaft portion and post afterbody, shaft portion is the hollow-core construction with hollow cavity, in hollow cavity, be installed with post core, hollow cavity and post core are cylindric, the diameter of hollow cavity is greater than the diameter of post core, and the length of post core is less than the length of hollow cavity.The utility model is difficult for sawed-off, safe and practical.Particularly, when saw blade saw shaft portion hollow cavity and and after post core comes in contact, post core can roll with the dragsaw action of saw blade, so, can make saw blade be difficult to form a fixing kerf on post core, thereby also just can significantly strengthen sawed-off difficulty, high safety, even if thereby and finally can sawed-offly also can expend and compare sawed-off more time of existing lock and strength and increase the time cost of larceny.In like manner, the embedded ball of post head also can roll with dragsaw action, thus, can effectively check utilize saw blade class instrument via post head saw into larceny.
Description
Technical field
The utility model relates to field of lockset, relates in particular to a kind of anti-saw lock.
Background technology
Known, between doorframe and door body, there is crack between a door and its frame, therefore robber can utilize saw blade to put in crack between a door and its frame the lockset being loaded on door is cut to saw, thereby can open the doors and implement theft with the lock of the sawed-off lockset of saw exactly specifically, and the lock of existing lockset is solid post, such lock structure is easily sawed-off, poor stability.
Utility model content
In view of this, technical problem to be solved in the utility model is: provide one to be difficult for sawed-off, safe and practical anti-saw lock.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of anti-saw lock, comprise there is post head, the lock body of shaft portion and post afterbody, wherein, described shaft portion is the hollow-core construction with hollow cavity, in described hollow cavity, be installed with post core, described hollow cavity and post core are cylindric, and the diameter of described hollow cavity is greater than the diameter of described post core, and the length of described post core is less than the length of described hollow cavity.
As preferably, in described post head, be embedded with can rolling ball.
As preferably, described post head, shaft portion and post afterbody are irony, and described post core and ball are steel.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model is difficult for sawed-off, safe and practical.Particularly, when saw blade saw shaft portion hollow cavity and and after post core comes in contact, post core can roll with the dragsaw action of saw blade, so, can make saw blade be difficult to form a fixing kerf on post core, thereby also just can significantly strengthen sawed-off difficulty, high safety, even if thereby and finally can sawed-offly also can expend and compare sawed-off more time of existing lock and strength and increase the time cost of larceny.In like manner, the embedded ball of post head also can roll with dragsaw action, thus, can effectively check utilize saw blade class instrument via post head saw into larceny.
