Description

Anti-pick bicycle lock

The utility model relates to a kind of bicycle lock, especially a kind of Antipicking bicycle lock.

Widely used in the past bicycle locking lock body is connected by aluminium matter rivet with lock nut, lock core assembly fixing and snap in lock is that structural disadvantages such as monolock tongue makes its very easy being pried open, though recently there are many Antipicking bicycle locks to come out, or because of complex structure or too high or because of relating to former thereby not seen widespread use such as production technology change because of price.

The purpose of this utility model will provide a kind of bicycle lock exactly, makes that it had both had that the ordinary bicycle lock construction is simple, production, installation, easy to use, and cheap advantage has good pick-proof performance again.

Structure of the present utility model is: at a Bicycle Anti-Picklock of being made up of lock core, lock housing, retainer and spring, it is characterized in that lock core is always by lock core, snap, lock core locating piece and lock core spacer ferrule constitute, in the middle of two locating pieces of lock core vent in the sides of a garment are fixed on, lock core assembly and lock housing are prevented back that stubborn bolt fuses, snap has hairpin shape dead bolt, and has grand " partly " opening of two-phase on the retainer that snap matches; Feature of the present utility model is that also the bolt head of preventing back stubborn bolt has two relative recesses, size 1/4th bolt heads of each recess; Lock core assembly and lock housing are prevented back that stubborn bolt fuses.

The purpose of this utility model realizes by following measure: the monolock tongue that changes ordinary bicycle lock for two tongue hairpin shape snaps as shown in Figure 4, the retainer that changes single standard-sized sheet mouth is for there being two opening retainers of two " half openings ", as enclose shown in 3, two tongue snaps cooperatively interact with two opening retainers, needing only the lock core assembly when snap closes is not moved, effect because of hairpin shape dead bolt, retainer can not rollback, can not be gone up or prize down by sled, retainer can't be opened, have only when snap is opened, retainer could be backed out next time in the effect of spring and open, fix for making the lock core assembly, will be by lock core (5), the lock core assembly that snap (6) lock core locating piece (4) and lock core spacer ferrule (8) constitute, with as shown in Figure 7 prevent back stubborn steel bolt (7) make its with the lock body fuse, simultaneously with preventing back that stubborn steel bolt replaces aluminium matter rivet, and be connected the lock body in aggregates with lock nut as shown in Figure 5 by the lock core locating piece, as Fig. 1, shown in Figure 2, the anti-sled intensity of lock housing has improved simultaneously greatly as long as the lock core spacer ferrule is not pried open as shown in Figure 6 like this, both just having locked body or lock nut one jiao or one side is pried open, snap just moves, and retainer is just opened, thereby this lockset has good pick-proof performance.Agent structure and ordinary bicycle that simultaneously should lock locked the same substantially, thereby had both simple in structurely, produces advantage easy to install, cheap.
