Abstract

The utility model discloses a bicycle lock with a new structure. The existing bicycle locks have a stopping blocking mechanism, which is easy to be poked or unclenched. The utility model provides a horseshoe-shaped bicycle lock, having two stopping blocking mechanisms of a number matching lock and a spring lock, improving the safety and the firmness of a lock, overcoming the defects of the existing bicycle locks.

Description

Bicycle lock with double-safety device

The utility model belongs to a kind of lockset.

Bicycle lock is an important accessory of bicycle, be used widely owing to easy to use, but this lock is owing to have only a billiards lock structure, and safety is poor, is opened or pries open by bucket easily.

The utility model proposes for this defective of safety difference that solves existing shape of a hoof lock just.

The lock that the utility model proposed has two parts control device, promptly digital combination lock and cylinder lock.The lock that the utility model proposed can be made into two kinds of form of structure, as shown in Figure 1 a kind of, it is the side that digital combination lock 6 and cylinder lock 9 are positioned at lock body drain pan 1, lock cylinder 11 links into an integrated entity with pinion 10, lock core is also opened the chute of bolt 12 (in the lock body bottom by slip, do not draw on the figure), bolt top is opened in slip a wedge 4 and a voussoir 8, and the front end of wedge 4 is inserted in the middle part chute of safety plug 3.Figure 1 shows that blocking, in the time will opening lock, at first, make the space of digital phase-locking aim at safety plug 3, then key is inserted in the eyelet of lock core 11 good digital phase-locking, upwards promote to slide again to open bolt 12, at this moment, the voussoir 8 of sliding bolt front portion and gear 10 break away from, and wedge 4 promotes safety plug 3 and enters in the space of digital phase-locking, no longer to lock Beam 13 start-stops action usefulness, lock Beam is issued to opening in the effect of extension spring 2.Beam is pulled in the process at lock, and pinion 10 is also driven and rotates.When wanting locking, the key pinion that lock core is inserted in turn rotates thereupon, drives lock Beam rotation and reaches locked position of coupler, and safety plug 3 will be locked wedge yoke under spring 5 effects dead.Another kind of form of the present utility model as shown in Figure 2, numeral combination lock 16 and cylinder lock 24 lay respectively at the both sides of lock body drain pan 18, cylinder of spring lock 25 and switch pin 23 connect together, and pull safety plug 15 that fixing button 14 can make opposite side and move along the chute of lock body.Figure 2 shows that blocking, in the time will opening lock, at first, pull safety plug 15 then backward, make in its space that enters digital phase-locking good digital phase-locking, the turn fixing button is fixed on this position it then, key is inserted in the lock core 25, the turn key drives switch pin 23 and returns again, and loses the stopping function to lock Beam 20, at this moment lock Beam and under the effect of big extension spring 19, be pulled, reach opening.When wanting locking, press handle 21 to pressing down, when arriving locked position of coupler, switch pin 23 enters under the effect of extension spring 22 in the groove of lock Beam, plays the effect of stop, unscrews fixing button 14 again, make safety plug 15 also enter the groove of lock Beam front end, play dual stop safety effect.Convenient and increase safety effect can be done the head of safety plug and switch pin oblique angle at 45 form for locking, and digital combination lock is made three array structure forms.

The dual fail-safe lock soundness that the utility model proposes is good, high safety, and difficult quilt is disclosed out or is pried open, and sensitivity is good, and unlatching and locking are convenient.

Fig. 1, Fig. 2 are respectively two embodiment of the present utility model.1,18 is the lock body drain pan among the figure, 2,19 are extension spring, and 3,15 is safety plug, and 5,7,17,22 is little spring, 6,16 is digital phase-locking, 9,24 is pin tumbler lock body, and 11,25 is lock core, and 13,20 are lock Beam, 12 is to slide to open bolt, 4 and 8 are respectively out the wedge and the voussoir of bolt front portion, and 14 is fixing button, and 21 is handle.
