Abstract
It the utility model is related to the technical field of lock core, especially a kind of easily broken anti-violence lock cylinder, with lock housing, at least one end offers easy fault trough in the lock housing, and the easily fault trough is by the half of lock housing is divided into the frangible portions being exposed at outside door body and is hidden in inside door body not frangible portions；After lock housing is by brute force attack, the frangible portions will be broken, but the not frangible portions will be retained in inside door body, it is ensured that the remaining part of lock core is difficult to by brute force attack again, ensures lockset safety.The lock core can only be broken the part being exposed at outside door body under violence, so as to reduce the size outside the exposed door body of lock core, to avoid lock core from causing lock core to fail by secondary violence.
Description
Technical field
The technical field of lock core is the utility model is related to, especially a kind of easily broken anti-violence lock cylinder.
Background technology
Lock core is the major part that control lock is opened, and it can be rotated and drive locking bolt to move with key is supporting.Conventional lock
Core generally use is monoblock type steel structure, because intermediate portion bit comparison is weak, therefore is held very much after by extraneous larger destructive power
Easily there is the phenomenon that middle part fractures, ultimately cause whole lock core and scrap.
The content of the invention
The technical problems to be solved in the utility model：In order to overcome the deficiencies in the prior art, there is provided a kind of easily broken
Anti-violence lock cylinder, the part being exposed at outside door body can only be broken under violence, so as to reduce the size outside the exposed door body of lock core,
To avoid lock core from causing lock core to fail by secondary violence.
The utility model solves technical scheme used by its technical problem：A kind of easily broken anti-violence lock cylinder, there is lock housing,
At least one end offers easy fault trough in the lock housing, the easily fault trough half of lock housing is divided into be exposed at it is easy outside door body
Disconnected part and the not frangible portions being hidden in inside door body；After lock housing is by brute force attack, the frangible portions will be broken,
But the not frangible portions will be retained in inside door body, it is ensured that the remaining part of lock core is difficult to, by brute force attack again, ensure
Lockset safety.
Further specifically, in above-mentioned technical proposal, the easily fault trough is shaped as rectangle.
Further specifically, in above-mentioned technical proposal, the width of the frangible portions is 10~15mm.
Further specifically, in above-mentioned technical proposal, the width of the easily fault trough is 0.3~2mm.
Further specifically, in above-mentioned technical proposal, the lock housing is by any one in copper material, copper alloy or aluminium alloy
Kind is made.
The beneficial effects of the utility model：The easily broken anti-violence lock cylinder, by opening up easy fault trough in lock housing, under violence
The part being exposed at outside door body can only be broken, so as to reduce the size outside the exposed door body of lock core, to avoid lock core by secondary
Violence causes lock core to fail.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments described in the application, for those of ordinary skill in the art, before creative work is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 top view.
In figure marked as：1st, lock housing；2nd, easy fault trough；1-1, frangible portions；1-2, non-frangible portions.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Embodiment 1：
See Fig. 1 and Fig. 2, a kind of easily broken anti-violence lock cylinder of the present utility model has lock housing 1, and lock housing 1 is closed by copper material, copper
Any one in gold or aluminium alloy is made, and one end in lock housing 1 offers easy fault trough 2, and easy fault trough 2 is shaped as rectangle, easily
The width of fault trough 2 is 0.3~2mm, easy fault trough 2 half of lock housing 1 is divided into the frangible portions 1-1 that is exposed at outside door body and
The not frangible portions 1-2 being hidden in inside door body, frangible portions 1-1 width are 10~15mm.When lock housing 1 is by brute force attack
Afterwards, frangible portions 1-1 will be broken, but frangible portions 1-2 will be retained in inside door body, it is ensured that the remaining part of lock core is difficult to
By brute force attack again, ensure lockset safety.
The easily broken anti-violence lock cylinder, easy fault trough 2 is opened up by one end in lock housing 1, can only be broken under violence exposed
Part outside door body, so as to reduce the size outside the exposed door body of lock core, to avoid lock core from causing lock core by secondary violence
Failure.
Embodiment 2：
Compared with Example 1, difference is：The both ends of lock housing 1 offer easy fault trough 2.
The easily broken anti-violence lock cylinder, easy fault trough 2 is opened up by the both ends in lock housing 1, can only be broken under violence exposed
Part outside door body, so as to reduce the size outside the exposed door body of lock core, to avoid lock core from causing lock core by secondary violence
Failure.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
