Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, 2, 3, there is for the utility model a kind of specific embodiment of the U-shape lock structure of Double-lock-core.This embodiment comprises U-shape lock beam 2 and the lock body 1 with U-shape lock beam 2 one end rotary setting, the other end of U-shape lock beam 2 arranges locked groove 21, lock body 1 is provided with the slot 11 inserted for U-shape lock beam 2 relative to the other end of U-shape lock beam 2 round end, slot 11 side is disposed with main lock core 3 and auxiliary lock core 4, the end of main lock core 3 is provided with the locking bolt 5 coordinated with locked groove 21, and main lock core 3 and locking bolt 5 interlock open or close U-shape lock; The end of auxiliary lock core 4 is provided with block piece 41, and auxiliary lock core 4 and block piece 41 link and stop or get out of the way space for locking bolt 5 activity.Adopt Double-lock-core to coordinate the structure of locking, design main lock core 3 coordinates with locking bolt 5 and link, inserts locking bolt 5 activity realization unlatching and locking in the axial direction when key rotates main lock core 3; And before main lock core 3 is unblanked, devise again the structure of auxiliary lock core 4 and block piece 41, auxiliary lock core 4 and block piece 41 are positioned at the rear of relative locking bolt 5, the setting of block piece 41 for stopping locking bolt 5, when auxiliary lock core 4 is locked, block piece 41 presses close to locking bolt 5, at this moment because block piece 41 blocks locking bolt 5, even if insert key to open main lock core 3, locking bolt 5 can not be movable, therefore turn motionless main lock core 3, therefore achieve the function of locking; After the key operated auxiliary lock core 4 of use, block piece 41 is movable backward, abdicates the activity space of locking bolt 5, thus main lock core 3 can open locking bolt 5.The structure of above Double-lock-core must be first open auxiliary lock core 4 could continue to open main lock core 3, achieves the double protection to U-shape lock lock core and latch member, increases the difficulty that thief destroys lock core or unblanks, improve the anti-theft effect of U-shape lock; The latch-up structure overall compact that on Double-lock-core, lock and locking bolt coordinate, spacing or cooperation is movable stable, and U-shape lock locking firmly, and is not easily destroyed.
As a kind of detailed description of the invention of improvement, block piece 41 is set for the eccentric the secondary lock post in auxiliary lock core 4 end, auxiliary lock core 4 rotarily drive secondary lock post near or leave the end of locking bolt 5.The rotation of auxiliary lock core 4 can drive secondary lock post movable, thus realizes the activity axially of the relative locking bolt 5 of secondary lock post, and stop or get out of the way space to locking bolt 5 activity, structure is simple, reaches good locking effect.
As a kind of detailed description of the invention of improvement, on main lock core 3, eccentric setting has master lock post 31, and locking bolt 5 is provided with the mating groove 51 matched with master lock post 31.Main lock core 3 eccentric setting master lock post 31, during insertion key rotation main lock core 3, master lock post 31 is in the axially activity of locking bolt 5, and being linked by master lock post 31 and the mating groove 51 of locking bolt 5 achieves the axially activity of locking bolt 5, can realize unlatching and locking.
As a kind of detailed description of the invention of improvement, locking bolt 5 is cylinder, and mating groove 51 is arranged on locking bolt 5 ringwise.Cylindrical locking bolt 5 structure rotates the cooperation that can't have influence on mating groove 51 and master lock post 31, rational in infrastructure, ensures master lock post 31 and the good long-term cooperation of locking bolt 5, not easily occurs stuck, guarantee the Long-Time Service of U-shape lock.
As a kind of detailed description of the invention of improvement, lock body 1 is closely arranged with the containment vessel 12 of metal, containment vessel 12 covers the periphery of main lock core 3 and auxiliary lock core 4 and exposes lockhole.The setting of containment vessel 12 enhances the structure of lock body 1, and the periphery covering main lock core 3 and auxiliary lock core 4 plays a good protection, and the survivable lock core of thief, strengthens lock core, improve theftproof performance.
As a kind of detailed description of the invention of improvement, containment vessel 12 and be respectively arranged with anti-drilling sheet 13 between main lock core 3 and auxiliary lock core 4.For improving the survivability of lock core further, arrange anti-drilling sheet 13 to protect lock core, the entirety that is connected with containment vessel 12 covers lock core, ensures the theftproof performance of lock core.
As a kind of detailed description of the invention of improvement, anti-drilling sheet 13 can in containment vessel 12 and the space formed between main lock core 3 and auxiliary lock core 4 axial rotation, anti-drilling sheet 13 is provided with the rectangular opening making key pass through.By above structural defence lock core; anti-drilling sheet 13 will forward the slotting keyhole of rectangular opening aligning to just can insert key; can the person of avoiding theft insert the unmatched instrument stolen, the large I of rectangular opening is designed to just can pass key, ensures the covering of anti-drilling sheet 13 pairs of keyhole maximum areas.
