Description
The utility model belongs to lockset, particularly with the locks adapted for bicycle of combination coded lock.
At present,, all kinds of locksets are installed on the bicycle,, also are used on the bicycle, become the bicycle lock of band coded lock because coded lock has good confidentiality for the safe handling of bicycle.The bicycle lock of this band coded lock is made up of lock body, dead bolt, dead bolt return spring, combination disk, backing pin, and its using method is, the rotational password dish, align the rectangular indentation of each combination disk, backing pin just can be withdrawn into by the control flume on the dead bolt in the rectangular indentation on the combination disk, realizes that dead bolt opens.The deficiency of its existence is that the shape of breach should not be very accurate to getting when contraposition, causes with the backing pin collision deformation reliability that influence is unblanked easily.
The purpose of this utility model is, adopts concealed installation combination disk form, changes breach section configuration on the combination disk, makes a scarce circular portion contraposition that drives on two combination disk, realizes the unlatching of lock, to improve safety that bicycle lock uses and reliable.
The key combination bicycle lock of exempting from of the present utility model, form by lock body, dead bolt, dead bolt back-moving spring, cipher lock, unlatching axle, it is characterized in that, cipher lock is the coaxial two-layer combination disk that is provided with, each combination disk is scarce toroidal, and last combination disk periphery is carved with the locating slot of 15 triangular sections, respectively is provided with a backing pin on the card of upper and lower two combination disk, but the backing pin of combination disk is down given in the backing pin power transmission of last combination disk, drives combination disk rotation down; On the lock body of combination disk one side, be provided with little spring, the extension of little spring is adjacent to the locating slot of combination disk periphery; Open axle and be provided with the control catch, be provided with small extension spring on the lock body of opening axle one side, the control catch is under the affecting of small extension spring, in the control flume of wedging dead bolt.
The using method of exempting from the key combination bicycle lock of the present utility model is, with the knob of hand to the right rotation combination disk, rely on feel to make down the scarce circular portion of combination disk align the control backing pin direction of opening axle, to the knob of anticlockwise combination disk, rely on feel to make the scarce circular portion of combination disk align the control backing pin direction of opening axle again; With the moving knob of opening axle of hand-screw, the control catch of opening axle can be thrown off the control flume of dead bolt, realizes unblanking again.When needs lock bicycle, the dead bolt moving process can make in the control flume of the control catch wedging dead bolt of opening on the axle, realizes the lock car.
The utility model has the advantages that, adopt the private mark control handle, the two groups of upper and lower combination disk put in place and can unblank, by each combination disk plane totally 30 calculating between 15 grooves and 15 grooves are arranged, 30 * 30=900 number of combinations can be arranged altogether, have moderate, the easy to use advantage of safety.Do not open the lock with the key, can not lose the worry of key.Rely on feel to judge the private mark number when adopting knob, no matter all can accurately unblank at daytime or night.Simple structure, easy to manufacture, cost is lower.Be applicable to that bicycle or other non power driven vehicles are with locking.
