Abstract
The utility model relates to an anti-theft lock for a bicycle, comprising a lock body 1, a lock rod mechanism 2, a locking mechanism 3, and a code interlocking mechanism 4. The lock rod mechanism 2 comprises a lock rod 5, a lock rod sleeve 6, and a spring 7. The locking mechanism 3 comprises a lock core 12, a shifting fork 13, a lock tongue 14, and a spring 15. The code interlocking mechanism 4 comprises a slide block 17, a rotary rod 16, a spring sheet 18, a code disk 19, and a shifting rod 20. Due to the fact that a circular arc-shaped long lock rod is not adopted by the anti-theft lock for a bicycle, only the lock rod mechanism 2, the locking mechanism 3, and the code interlocking mechanism are arranged in the lock body, and the lock body is riveted to death by a cover. The anti-theft lock for a bicycle is not easily prized, and thus, the anti-theft performance of the anti-theft lock for a bicycle is very strong.
Description
The utility model relates to a kind of anti-theft lock for bicycle.
Though existing on the market anti-theft lock for bicycle structure is varied, but owing to generally adopt the long locking bar of circular arc, thereby lock body also must adopt circular arc, and this circular arc lock body structurally can only be by two altogether, lock body is very easily pried open, although people have designed many kinds of schemes on locking mechanism, because the problem of above-mentioned essence end solves, the theftproof of theftproof lock is not strong.
The theftproof lock that provides a kind of theftproof strong is provided the purpose of this utility model.
The utility model is not owing to adopt the long locking bar of circular arc, and just with locking bar mechanism, locking mechanism, interlocking mechanism are contained in the lock body, with lid it rivetted again, make it to be difficult for prying open, thereby theftproof is extremely strong.
Below in conjunction with accompanying drawing the utility model is described in detail
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a sectional view of the present utility model
Fig. 3 is the structural representation of the utility model locking bar mechanism 2
Fig. 4 is a scheme of installation of the present utility model
The utility model is by lock body 1, locking bar mechanism 2, locking mechanism 3, password interlocking mechanism 4 is formed, locking bar mechanism 2, locking mechanism 3, password interlocking mechanism 4 are contained in the lock body 1, and wherein locking bar mechanism 2 comprises locking bar 5, locking bar cover 6, spring 7 has elongated slot 8 and breach 9 on locking bar cover 6, be provided with projection 10 on locking bar 5, locking bar 5 is contained in the locking bar cover 6, projection 10 is stuck in the elongated slot 8, and 7 on spring is contained between locking bar 5 and the locking bar cover 6, also is provided with boss 11 on lock body 1, locking mechanism 3 is by lock core 12, shift fork 13, dead bolt 14, spring 15 is formed, shift fork 13 is contained in the end of lock core 12,14 of dead bolts are contained in the chute of lock body 1, one side on the step surface that leans against dead bolt 14 of shift fork 13, another side leans against on the dwang 16 of password interlocking mechanism 4, between lock body 1 and dead bolt 14, spring 15 is housed, password interlocking mechanism 4 is by slide block 17, dwang 16, spring leaf 18, combination disk 19, driving lever 20 is formed, and an end of dwang 16 is fixed on the pillar of lock body 1, can rotate around pillar, the other end is stuck in the skewed slot of slide block 17, combination disk 19 is fixed on the lock body 1, and driving lever 20 is contained in the central authorities of combination disk 19, and its end contacts with shift fork 13 on leaning against dwang 16.
When using the utility model lock car, pull back locking bar cover 6, projection 10 on the locking bar 5 slides in elongated slot 8, and snap in the breach of locking bar cover 6, promote locking bar cover 6 more forward, locking bar cover 6 promotes locking bar 5 and inserts forward on the lock body sheath 22, and block projection 10 by dead bolt 14, locking bar 5 can not be retreated, at this moment, owing on lock body 1, be provided with boss 11, projection 10 is ejected breach 9, for implementing above-mentioned moving getting ready next time, when need were unblanked, rotational lock core 12 made shift fork 13 stir dead bolt 14 and withdraws from, spring 7 is towed back to locking bar 5, lock is opened, when need access to your password further locking, pushed slide block 17 left, dwang 16 is under the effect of spring leaf 18, be stuck in the skewed slot of slide block 17, slide block 17 can not be withdrawed from, at this moment, because slide block 17 has blocked shift fork 13, shift fork 13 can not be rotated, have key also can't unblank, must utilize password lock could be opened, rotational lock core 12 at first slightly, shift fork 13 is rotated slightly no longer keep off between dwang and dead man, stirred password, promote driving lever 20 by correct digit, one end of driving lever 20 promotes dwang 16 and lifts, withdraw from skewed slot, slide block 17 is withdrawed from again, rotational lock core 12 is opened lock again.
