Description
Technical field
The utility model relates to a kind of lock core, and especially a kind of lock core shell, particularly a kind of two ends all can the lock core shells of the anti-turn-knob of anti-folding.
Background technology
As shown in Figure 1-2, current lock core shell (being more particularly the housing of an Europe type lock barrel), it comprises the first housing 1 and the second housing 2, first housing 1 and the second housing 2 are respectively equipped with lock gall hole (11, 21) and marble hole (12, 22), be respectively used to lock gall is installed and controls pellet, be connected by housing bridge 3 between first housing 1 and the second housing 2, first housing 1, second housing 2 and housing bridge 3 (are generally monoblock cast part or a monoblock unit through car for integral type structure, to cut etc. and process), the fixing hole 38 (being generally screwed hole) for the transverse direction be fixedly connected with door leaf is also had in housing bridge 3 centre position, be positioned at and locate to be formed (being namely provided with) inside housing bridge 3 and dial drag dialling of (shift fork or plectrum) to drag installation gap 4 for installing lock core between first housing 1 and the second housing 2.Current this Europe type lock barrel housing is easy to use, owing to there being two housings (i.e. the first housing 1, second housing 2), during use, a housing (first housing 1 or the second housing 2) is towards in door, another housing (second housing 2 or the first housing 1) is towards outdoors, people can realize locking a door and the object of opening the door in door, lock a door (i.e. popular " locking " said) and the object of opening the door can also realized outdoors simultaneously, switch gate is convenient, and plays necessarily antitheft effect.But there is following problem in current this lock core shell:
1, first housing 1, second housing 2 and housing bridge 3 are integral type structure, can not relative variability between first housing 1 and the second housing 2, when robber uses force (be generally adopt vice clamp) powerful bending, or twisting, or rotate a housing (being generally for being arranged on towards that housing (first housing 1 or the second housing 2) outdoors), owing to defining integral structure by housing bridge 3 between the first housing 1 and the second housing 2, when a housing is subject to violence, dynamics can act directly on housing bridge 3, again due between the first housing 1 and the second housing 2 and be positioned at place inside housing bridge 3 devise one dial drag installation gap 4, cause housing bridge 3 just can not do too large, housing bridge 3 generally makes thiner, like this at the first housing 1, second housing 2 is with the overall structure of housing bridge 3, housing bridge 3 just becomes structural weak parts, through bending several times repeatedly, twisting, under the active force rotated, be easy to rupture from housing bridge 3, whole lock will be made to lose antitheft object.Current many robbers have just found out this weak link of this Europe type lock barrel housing, and often directly employing vice sub-folder lives housing towards door outside, repeatedly firmly bends several times, twists or rotates, and housing just can be broken by moment, realizes the object of stealing.
2, fixing hole 38 is positioned on inherently weaker housing bridge 3, the structural strength of housing bridge 3 is reduced further, directly weakens the structural strength of whole lock core shell, reduce the anti-theft capability of whole lock.
