Description
Technical field
The utility model relates to the anti-theft device field, relates in particular to a kind of U-shaped coded lock.
Background technology
The cipher wheel long term exposure of existing coded lock is made dirty outside easily, is cracked by the people in order to prevent coded lock, can take often to change the method for unlocking cipher, the structures such as reversion button need to be set, but existing structure is simple not, it is very not convenient to cause changing password.After the self-locking of combination lock mistake, need to pry open lock, cumbersome.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, and a kind of U-shaped coded lock that keeps coded lock neatly, easily to change unlocking cipher is provided.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of U-shaped coded lock, comprise U-shape lock hook, the lock housing that supplies the U-shape lock hook to insert, it is characterized in that: also comprise the buckle that is fixed in the lock housing, the lock core group that is fixed in buckle, the lock core group comprises lock core shaft, cipher wheel and the reversion button that is positioned at lock core group central authorities and is connected with the lock housing end, the lock core shaft surface is provided with some breach, and cipher wheel and reversion button surface are provided with some resilient projection.
Aforesaid a kind of U-shaped coded lock, described lock housing are fastened by A shell and B shell and form, and the end of lock housing is provided with two side covers, and the side cover outside is equipped with button, and another side cover inboard is provided with stage clip.
Aforesaid a kind of U-shaped coded lock, described lock housing are provided with the dust cap that be used for to cover cipher wheel and reversion button that can move along lock housing.
Aforesaid a kind of U-shaped coded lock also comprises the lock tube that is fixed in the lock housing, and buckle is fixed in the lock tube.
Aforesaid a kind of U-shaped coded lock, described latch hook end is provided with groove, and described lock tube is provided with the projection corresponding with groove, presses button lock tube is moved, and projection is left groove and is unblanked with realization.
Aforesaid a kind of U-shaped coded lock, the resilient projection of reversion button is inserted lock core shaft's breach, promotes the reversion button and moves the resilient projection release lock mandrel breach that makes the reversion button in lock core shaft.
The single password wheel is provided with some resilient projection, when lock core shaft position certain (being the location positioning of breach in the lock core shaft), when turning to a certain numeral, do not have resilient projection to insert breach, this moment cipher wheel with lock core shaft without being fixedly connected with, turn to other when digital, flexible protuberance inserts breach, this moment, cipher wheel was fixedly connected with lock core shaft, when all cipher wheel are not fixedly connected with lock core shaft, and the cipher wheel state that unlocks at this moment.Press button, lock tube is moved to left, make the stage clip compression, the projection of lock tube is left the groove of latch hook, and latch hook breaks away from lock housing, realizes unblanking.
Generally, the reversion button all is in such position: the resilient projection of reversion button is inserted lock core shaft's breach, realizes the locking of lock core shaft, when rotational password is taken turns, can't make lock core shaft's rotation.When needing reversion, promote reversion button move to right in lock core shaft (moving toward the direction of leaving cipher wheel), the resilient projection of reversion button is left lock core shaft's breach, lock core shaft unlocks, can make lock core shaft's rotation this moment by rotational password wheel, and the position of lock core shaft's breach is moved, and determines behind the new password the reversion button toward pushing back again, because breach is a plurality of, the reversion button back postpones the resilient projection of reversion button and inserts another lock core shaft's breach and realize locking.
The utility model arranges movably dust cap, can not only keep coded lock neatly and not to affect the input password unlocking, and is easy to operate; Reversion button and dependency structure are set, easily change unlocking cipher.
Description of drawings
Fig. 1 is structure explosive view of the present utility model;
Fig. 2 is structure chart of the present utility model and coded lock partial enlarged drawing;
Fig. 3 is unlocking condition figure of the present utility model;
Wherein, 1 lock core group, 2 dust caps, 3 buttons, 4a A shell, 4b B shell, 5a side cover 1,5b side cover 2,6 buckles, 7 latch hooks, 8 lock tubes, 10 pads, 12 stage clips, 13 latches, 14 grooves, 15 projections, 16 reversion buttons, 17 cipher wheel.
The specific embodiment
Figure is preferred embodiment of the present utility model, below in conjunction with figure the utility model is further described, wherein, 1 lock core group, 2 dust caps, 3 buttons, 4a A shell, 4b B shell, 5a side cover 1,5b side cover 2,6 buckles, 7 latch hooks, 8 lock tubes, 10 pads, 12 stage clips, 13 latches, 14 grooves, 15 projections, 16 reversion buttons, 17 cipher wheel.
According to Fig. 1-3, a kind of U-shaped coded lock, the lock housing that comprises U-shape lock hook 7, supplies U-shape lock hook 7 to insert, it is characterized in that: also comprise the buckle 6 that is fixed in the lock housing, the lock core group 1 that is fixed in buckle 6, lock core group 1 comprises lock core shaft (not shown), cipher wheel 17 and the reversion button 16 that is positioned at lock core group 1 central authorities and is connected with the lock housing end, the lock core shaft surface is provided with some breach (not shown), and cipher wheel 17 and reversion button 16 surfaces are provided with some resilient projection (not shown).Lock housing is fastened by A shell 4a and B shell 4b and forms, and the end of lock housing is provided with two side covers (side cover 1 5a, side cover 2 5b), and the side cover outside is equipped with button 3, and another side cover inboard is provided with stage clip 12.Lock housing is provided with the dust cap 2 that be used for to cover cipher wheel 17 and reversion button 16 that can move along lock housing.U-shaped coded lock also comprises the lock tube 8 that is fixed in the lock housing, and buckle 6 is fixed in the lock tube 8, and buckle 6 and lock tube 8 tools are provided with pad 10.Latch hook 7 ends are provided with groove 14, and described lock tube 8 is provided with the projection 15 corresponding with groove 14, press button 3 lock tube 8 is moved, and projection 15 is left groove 14 and unblanked realizing.The resilient projection of reversion button 16 is inserted lock core shaft's breach, promotes reversion button 16 and moves the resilient projection release lock mandrel breach that makes reversion button 16 in lock core shaft.Interfix by latch 13 between the parts.
The process of unblanking is: move dust cap 2 according to Fig. 2 and direction shown in Figure 3, this moment, cipher wheel 17 exposed, and stirred character wheel and made correct numeral concordant with the check mark line on the A shell 4a.Single password wheel 17 is provided with some resilient projection, when lock core shaft position certain (being the location positioning of breach in the lock core shaft), when turning to a certain numeral, do not have resilient projection to insert breach, this moment cipher wheel with lock core shaft without being fixedly connected with, turn to other when digital, flexible protuberance inserts breach, this moment, cipher wheel was fixedly connected with lock core shaft, when all cipher wheel 17 are not fixedly connected with lock core shaft, and cipher wheel 17 state that unlocks at this moment.Press button 3, lock tube 8 is moved to left, make stage clip 12 compressions, the projection 15 of lock tube 8 is left the groove 14 of latch hook 7, and latch hook 7 breaks away from lock housing, realizes unblanking.
