Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Fig. 1,2,3,4,5, for the present invention has a kind of specific embodiment of the U-shape lock of Double-lock-core.This embodiment comprises lock body 1 and the rotatable U-shape lock beam 2 be arranged on lock body 1, lock body 1 is disposed with two lock core grooves be arranged in order, the end of lock core groove is connected with the perpendicular set bar groove passed through mutually, the first lock core 3 and the second lock core 4 is provided with in two lock core grooves, the end of the first lock core 3 has the first lock 31 of eccentric setting, the end of the second lock core 4 has the second lock 41 of eccentric setting, is provided with locking bolt 5 in set bar groove; Second lock 41 matches with locking bolt 5 and links, and the second lock core 4 rotarily drives the second lock 41 and links with locking bolt 5 and open or close U-shape lock beam 2; First lock 31 is positioned at one end of locking bolt 5, and the first lock core 3 rotarily drives the activity space of the first lock 31 activity locking or release locking bolt 5.
Double-lock-core is adopted to coordinate the structure of locking, design the second lock core 4 to coordinate with locking bolt 5 and link, specifically the second lock core 4 eccentric setting second lock 41, insert axially movable at locking bolt 5 of the second lock 41 when key rotates the second lock core 4, achieve the axially movable of locking bolt 5 by the second lock 41 and the interlock of locking bolt 5, can realize opening and locking; And before the second lock core 4 is unblanked, devise again the structure of the first lock core 3 and the first lock 31, first lock core 3 is positioned at the rear of relative locking bolt 5 with the first lock 31, the setting of the first lock 31 for stopping locking bolt 5, when the first lock core 3 is locked, first lock 31 presses close to locking bolt 5, at this moment because the first lock 31 blocks locking bolt 5, even if insert key to open the second lock core 4, locking bolt 5 can not be movable, therefore turn motionless second lock core 4, therefore achieve the function of locking; After key operated first lock core 3 of use, the first lock 31 is movable backward, abdicates the activity space of locking bolt 5, thus the second lock core 4 can open locking bolt 5.The structure of above Double-lock-core must be first open the first lock core 3 could continue unlatching second lock core 4, 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, locking bolt 5 is provided with cannelure 51, second lock 41 is arranged in cannelure 51 and matches with locking bolt 5, the rotation of locking bolt 5 can't have influence on the cooperation of cannelure 51 and the second lock 41, rational in infrastructure, ensure the second lock 41 and the good long-term cooperation of locking bolt 5, not easily occur 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 lock body shell 11 of metal, lock body shell 11 covers the periphery of the first lock core 3 and the second lock core 4 and exposes lockhole.The setting of lock body shell 11 enhances the structure of lock body 1, and the periphery covering the first lock core 3 and the second 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, between lock body shell 11 and the first lock core 3, second lock core 4, be respectively arranged with anti-drilling sheet 12.For improving the survivability of lock core further, arrange anti-drilling sheet 12 to protect lock core, the entirety that is connected with lock body shell 11 covers lock core, ensures the theftproof performance of lock core.
As a kind of detailed description of the invention of improvement, axial rotation in the space that anti-drilling sheet 12 can be formed between lock body shell 11 and the first lock core 3, second lock core 4, anti-drilling sheet 12 is provided with the rectangular opening making key pass through.By above structural defence lock core; anti-drilling sheet 12 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 12 pairs of keyhole maximum areas.
As a kind of detailed description of the invention of improvement, also include dirt-proof boot 6, dirt-proof boot 6 is arranged on the position of relative first lock core 3 and the second lock core 4 on lock body shell 11, dirt-proof boot 6 is provided with the first perforate 61 of corresponding first lock core 3 and the second perforate 62 of corresponding second lock core 4, first perforate 61 and the second perforate 62 place are provided with mobilizable dust cap 63, and dust cap 63 is movable opens or closes the first perforate 61 and the second perforate 62.Lock core exposes and is easily subject to extraneous corrosion or the blocking of foreign material, and design dirt-proof boot 6 one aspect strengthens the position at lock core place, improves anti-damage ability further; On the other hand can the dust cap 63 of switch can available protecting lockhole, avoid pollutant to enter, extend the application life of lock core.
As a kind of detailed description of the invention of improvement, lock body 1 and lock body shell 11 are by the first pin 13 stationary positioned, dirt-proof boot 6 is set in position lock body shell 11 covering the first pin 13 place, and lock body 1, lock body shell 11 and dirt-proof boot 6 is by the second pin 14 stationary positioned.Adopt two pins to reach double effects that is fixing and location, the first pin 13 is covered by dirt-proof boot 6 after fixing lock body 1 and lock body shell 11, and improve the effect of protection, thief not easily destroys it.
