Specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As shown in Fig. 1,2,3,4,5, it is a kind of specific embodiment of the U-shape lock that the present invention has Double-lock-core.This embodiment
Including lock body 1 and the U-shape lock beam 2 being rotatably disposed on lock body 1, lock body 1 is disposed with two lock cores being arranged in order
Groove, the end of lock core groove is connected with the perpendicular set bar groove mutually passing through, and is provided with the first lock core 3 and the second lock in two lock core grooves
Core 4, the end of the first lock core 3 has the first lock 31 of eccentric setting, and the end of the second lock core 4 has the second of eccentric setting
Lock 41, is provided with locking bolt 5 in set bar groove；Second lock 41 is matched with locking bolt 5 linkage, and the second lock core 4 rotarily drives second
Lock 41 opens or closes U-shape lock beam 2 with locking bolt 5 linkage；First lock 31 is located at one end of locking bolt 5, the first lock core 3 rotating band
The activity locking of dynamic first lock 31 or the activity space of release locking bolt 5.
Using the structure of Double-lock-core cooperation locking, design the second lock core 4 and locking bolt 5 cooperation linkage, the specifically second lock core 4
Eccentric setting the second lock 41, when insertion key rotates the second lock core 4, the activity in the axial direction of locking bolt 5 of the second lock 41, passes through
Second lock 41 achieves the axially movable of locking bolt 5 with the linkage of locking bolt 5, that is, enable to open and locking；And in the second lock core 4
Before unlocking, devise the first lock core 3 and the structure of the first lock 31, the first lock core 3 is located at relative lock with the first lock 31 again
The rear of bolt 5, the first lock 31 be provided for stop locking bolt 5, when the first lock core 3 is locked, the first lock 31 presses close to locking bolt
5, at this moment because the first lock 31 blocks locking bolt 5, even if inserting key to open the second lock core 4, locking bolt 5 nor activity, therefore turn
Motionless second lock core 4, it is achieved that the function of locking；After using key operated first lock core 3, the first lock 31 is lived backward
Dynamic, concede 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 first be opened
Open the first lock core 3 and just can continue on the second lock core 4 it is achieved that double protection to U-shape lock lock core and latch member, increase
Thief destroys the difficulty of lock core or unlocking, improves the anti-theft effect of U-shape lock；The lock of lock and locking bolt cooperation on Double-lock-core
Fixed structure overall compact, spacing or cooperation is movable stable, and U-shape lock locking firmly, and is difficult to be destroyed.
As a kind of improved specific embodiment, locking bolt 5 is provided with cannelure 51, the second lock 41 is arranged on annular
Match with locking bolt 5 in groove 51, the rotation of locking bolt 5 does not interfere with cannelure 51 and the cooperation of the second lock 41, and structure is closed
Reason it is ensured that the second lock 41 and the good long-term cooperation of locking bolt 5, be less prone to stuck it is ensured that the life-time service of U-shape lock.
As a kind of improved specific embodiment, lock body 1 is closely arranged with the lock body shell 11 of metal, lock body shell
The periphery of 11 covering the first lock cores 3 and the second lock core 4 simultaneously exposes lockhole.The setting of lock body shell 11 enhances the structure of lock body 1,
Cover the first lock core 3 and the periphery of the second lock core 4 plays a good protection, the survivable lock core of thief, strengthen lock
Core, improves theftproof performance.
As a kind of improved specific embodiment, set respectively between lock body shell 11 and the first lock core 3, the second lock core 4
It is equipped with anti-drilling sheet 12.For improving the survivability of lock core further, arrange anti-drilling sheet 12 to protect lock core, with lock body shell 11
It is connected and overall cover lock core it is ensured that the theftproof performance of lock core.
As a kind of improved specific embodiment, anti-drilling sheet 12 can be in lock body shell 11 and the first lock core 3, the second lock core
Axial rotation in the space being formed between 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 go to rectangular opening be aligned and insert keyhole just pluggable key, can the person's of avoiding theft insertion steal not
The instrument of coupling, the size of rectangular opening may be designed to just may pass through key, to ensure anti-drilling sheet 12 to keyhole maximum area
Covering.
As a kind of improved specific embodiment, also include dirt-proof boot 6, dirt-proof boot 6 is arranged on lock body shell 11
Relative first lock core 3 and the position of the second lock core 4, dirt-proof boot 6 are provided with the first perforate 61 of corresponding first lock core 3 and correspond to
It is provided with mobilizable dust cap 63, dust cap 63 at second perforate 62 of the second lock core 4, the first perforate 61 and the second perforate 62
Movable open or close the first perforate 61 and the second perforate 62.Lock core exposes easily by the corrosion in the external world or blocking up of debris
Plug, design dirt-proof boot 6 one aspect strengthens the position at lock core place, improves anti-damage ability further；On the other hand switchable
Dust cap 63 can effective protection lockhole, it is to avoid pollutant enter, and extend the service life of lock core.
As a kind of improved specific embodiment, lock body 1 and lock body shell 11 pass through the first pin 13 stationary positioned, prevent
Dirt set 6 is set in the position covering the first pin 13 place on lock body shell 11, and lock body 1, lock body shell 11 and dirt-proof boot 6 pass through
Second pin 14 stationary positioned.To reach fixing and positioning double effectses using two pins, the first pin 13 is in fixing lock
Covered by dirt-proof boot 6 after body 1 and lock body shell 11, improve the effect of protection, thief is difficult it is destroyed.
As a kind of improved specific embodiment, at U-shape lock beam 2 and the rotatable engagement of lock body 1, it is provided with through hole, through hole
In be provided with two ends fluting female pin 15, on lock body 1, corresponding both sides are provided with male pin 16, and male pin 16 inserts female pin
Cooperation rotation in the groove of nail 15, lock body shell 11 wraps male pin 16 position.Adopt two male pins 16 as shown in the figure
Insert the Stability Analysis of Structures that female pin 15 cooperation rotates, be easy to manufacture and assemble, lock body shell 11 wraps and plays at rotatable engagement
The effect reinforced, thief is also difficult to partly be destroyed with being rotatably connected of lock body 1 from U-shape lock beam 2, improves U-shape lock
Anti-theft capability.
