Abstract
The invention relates to an anti-prying, anti-theft and instant-unlocking lock core, and the lock core comprises a lock shell 1, an inner core 2 and a return spring 8, wherein a seal cover 10 is used for arranging the inner core 2 in the lock shell 1 and realizing limit and telescopic sliding of the inner core 2, and a key hole 7 corresponding to the inner core 2 is formed at one end of the lock shell 1; when the anti-prying, anti-theft and instant-unlocking lock core is unlocked, a legal key is inserted for aligning concave grooves on a blade 3, a sliding block spring 6 is used for pressing the sharp angle part of a sliding block 5 into the grooves of the blade 3, the other part of the sliding block 5 is out of control of the lock shell 1, the key is pushed continuously and then a lockset is unlocked. If an illegal key is inserted into the key hole 7, as long as one groove on the blade 3 is not aligned, the sliding block spring 6 can not press the sharp angle part of the sliding block 5 into the grooves of the blade 3 and the inner core 2, then the sliding block 5 is still controlled by the lock shell 1 and can not move, the inner core 2 is in idle slipping state in the lock shell 1 and the lockset cannot be unlocked.
Description
Technical field
The present invention relates to a kind of lock core, particularly a kind of pick-proof anti-theft instantly-opening locking core.
Background technology
At present, the lock core that the crowd knows all is revolving, mainly is made up of lock housing, inner core and key, need drive the inner core rotation with the hand key during unlatching, and inner core drives dead bolt again and opens lockset.And lock core all is to expose installation, keyhole also than broad all more than 2 millimeters, the robber holds and uses technical opening very much, or rotary locking cylinder by force, also can destroy lock core with boring, and lock core exposes also corrosion easily, reduces lockset application life etc.Because dead bolt all is telescopic work, controlling telescopic dead bolt with rotary lock core just needs to increase converting workpiece, has just increased cost, has also increased fault rate.
Summary of the invention
In order to overcome existing lock core all is the problem that exists with the key rotation, the present invention changes present rotary locking cylinder for telescopic by local for this reason, just changed the direction of motion of original lock core, this lock core also mainly is made up of lock housing 1 and inner core 2, inner core 2 is provided with blade 3, stage clip 4, slide block 5, slide block spring 6, keyhole 7, return spring 8 compositions, inner core 2 is encapsulated in lock housing 1 inside, also spacing telescopic slip, end on the lock housing 1 has and inner core 2 corresponding keyholes 7, and other end slide block 5 stretches out the control dead bolt.Insert legal key when unblanking, make the concave groove alignment on the blade 3, slide block spring 6 partly is pressed in the wedge angle of slide block 5 in the groove of blade 3, another part of slide block 5 breaks away from lock housing 1 control, continue to promote key, key promotes inner core 2 again, and inner core 2 drives slide block 5 again and stretches out the control lock tonguing, and lockset is opened.As long as withdraw from key during locking, stage clip 4 makes the groove dislocation of blade 3, and blade 3 is released grooves with slide block 5 again, and another part of slide block 5 inserts again in the control hole on the lock housing, and slide block 5 is subjected to lock housing 1 control, lockset closure.If illegal key inserts keyhole 7, as long as the groove on the blade 3 has one can not align, slide block spring 6 just can't partly overwhelm the wedge angle of slide block 5 in the groove of blade 3, even continue to promote key, inner core 2 also can't drive slide block 5 actions, and inner core 2 is empty sliding state in lock housing 1.The technical scheme that the technical problem to be solved in the present invention is taked is: open one and inner core 2 corresponding keyholes in lock housing 1 bottom of tubbiness, be respectively equipped with blade 3, stage clip 4, slide block 5, slide block spring 6, keyhole 7, return spring 8 compositions on the inner core 2, good the above-mentioned component-assembled of inner core 2, be contained in lock housing 1 inside, control flexible distance well, also can control flexible distance by spacer pin is installed.
Beneficial effect:
Simple in structure, with low cost, built-in be inner core, not perishablely can also prevent effectively that the robber from forcing twisting or boring bad lock core, keyhole is lower than 1 millimeter width, the robber is difficult to technical opening.Need not twist key, the locking of unblanking is convenient especially, more do not exist and twist off the key phenomenon.
Description of drawings:
Accompanying drawing 1 is the vane type view in transverse section of the pick-proof anti-theft instantly-opening locking heart of the present invention.
Illustration; 1, lock housing, 2, inner core, 3, blade, 4, stage clip, 5, slide block, 6, the slide block spring, 7, keyhole, 8, return spring.
The specific embodiment from accompanying drawing as seen, this lock core mainly is made up of lock housing 1, inner core 2, two large divisions, end on the lock housing 1 has and the corresponding keyhole 7 of inner core, the middle part is provided with control hole so that control slide block 6, and inner core 2 is made up of blade 3, stage clip 4, slide block 5, slide block spring 6, keyhole 7, return spring 8 again.Component-assembled on the inner core 2 is installed in lock housing 1 inside after good, in legal key is inserted keyhole 7, groove alignment, slide block spring 6 on the moving vane 3 partly are pressed in the wedge angle of slide block 5 in the groove of blade 3 and inner core, another part of slide block 5 breaks away from lock housing 1 control, continue to promote key, key promotes inner core 2 again, and inner core 2 drives slide block 5 again and stretches out the control dead bolt, and lockset is opened.Stop thrust, return spring 8 promotes whole inner core and resets, and withdraws from key, stage clip 4 is with the dislocation of the Baltimore groove on the blade 3, and blade 3 is partly released blade and inner core groove with the wedge angle of slide block 5 again, and another part of slide block 5 inserts again in the lock housing control hole, slide block 5 is subjected to lock housing 1 control, lockset closure.If illegal key inserts keyhole 7, as long as the groove on the blade 3 has one can not align, slide block spring 6 just can't partly overwhelm the wedge angle of slide block 5 in the groove of blade 3 and inner core 2, slide block 5 still can not be moved by lock housing 1 control, even continue to promote key, inner core 2 also can't drive slide block 5 actions, and inner core 2 is empty sliding state in lock housing 1, and lockset can't be opened
