Description

The bicycle theft-prevention coded lock

The utility model relates to the anti-theft column lock that uses on a kind of bicycle.

Bicycle lock on the market is of a great variety now, and version is various.When the great majority lock was installed on the bicycle, whole lock all was exposed in broad daylight.Therefore no matter the structure of these locks how, stealer adopts means such as prize, saw, bore, cut to destroy by lock, makes lock lose the function of guarding bicycle, allows stealer that bicycle is ridden away.A kind of concealed installation spiral anti-theft lock for bicycle among the standpipe before the front fork tube of bicycle and spider has also newly appearred on the current market.The handgrip of bicycle can not be rotated.Though means such as this lock can not adopt sled, cut are destroyed it, still its lock core can be destroyed with the means of boring.Because the lock core of this lock is again the dead bolt of this lock, therefore as long as lock core is destroyed, dead bolt is also simultaneously destroyed.So the handgrip of bicycle also just can not pin.Therefore this lock can not be antitheft fully.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of safety is extremely strong, conservative factor is very high, very easy to use and provide, and is especially destroyed the anti-theft lock for bicycle that lock can not be opened at lock core.

The purpose of this utility model realizes by following technical measures: this anti-theft lock for bicycle mainly is made up of lock body, built-in lock, scrambler, dead bolt and attaching parts.Wherein built-in lock and scrambler all are fixed on the lock body, and scrambler is positioned at after the built-in lock.Meanwhile below the lock core of built-in lock, be provided with a miniature gears.And the profile of dead bolt be "

" shape, on the tongue bar of dead bolt, have and miniature gears mating teeth bar.Afterbody at dead bolt has a cross bar.The locking plate of three energy interactions is housed below scrambler in addition.And on every locking plate, all have radially groove.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

The utility model is described in further detail below in conjunction with embodiment: this anti-theft lock for bicycle mainly is made up of lock body (1), built-in lock (3), scrambler (2), dead bolt (9) and attaching parts (4).Built-in lock (3) and scrambler (2) all are fixed on the lock body (1).Wherein built-in lock (3) is fixed on the front, and scrambler (2) is fixed on the back of built-in lock (3).And profile be " " dead bolt (9) also be inserted on the lock body (1).It can go up forward and backward slip at lock body (1).Simultaneously on the tongue bar of dead bolt (9), have tooth bar (11), and the afterbody of dead bolt (9) has a cross bar.Below the lock core of built-in lock (3), be provided with a miniature gears (8) in addition.This miniature gears (8) is meshed with tooth bar (11) on the dead bolt (9).And the locking plate (10) of three energy interactions is arranged, and all have the groove of radially going up on every locking plate (10) below scrambler (2).This groove can hold dead bolt (9).This anti-theft column lock when installing and using, also should be earlier respectively on the cylinder of the cloudy tube (5) of bicycle, bore a hole on the cylinder of preceding fork shaft (6) and on the cylinder of handgrip axle (7), must allow the axis in these three holes overlap simultaneously, make the unification of three holes.The through hole of this three holes unification can allow dead bolt (9) can put in, stretch out.

This anti-theft column lock in use when owner will lock bicycle, at first is inserted into key in the lockhole of built-in lock and key, lock core is rotated, so the miniature gears below the lock core also rotates thereupon.Miniature gears has the dead bolt of tooth bar to travel forward with regard to driving on it like this, allows the front portion of dead bolt protrude into simultaneously in three holes of being bored on cloudy tube, preceding fork shaft and the handgrip axle.Follow the word handle of first rotational password device, allow groove dislocation on three locking plates of scrambler, dead bolt can't be return.Extract key again, so the preceding fork shaft of bicycle and handgrip axle are just blocked by dead bolt.Handgrip can not change the insurance safe condition that bicycle is in can not ride and can not push away away.When owner will use car, as long as press earlier the word handle that the password of defined is counted the rotational password device.So the groove part on three locking plates of scrambler is aimed at the cross bar of dead bolt afterbody.And then key is inserted key behind the lockhole of built-in lock, allow lock core to counter-rotation.So the miniature gears below the lock core just drives dead bolt and moves backward, the cross bar of its dead bolt afterbody enters in the groove on the locking plate, and the front portion of dead bolt just withdraws in the hole on fork shaft and the Handle axis in the past fully.The Handlebar of bicycle axle returns to state nimbly and freely again behind the taking-up key, and bicycle just can be ridden away.

The utility model has following advantage compared to existing technology: this theftproof lock has adopted sealed built-in lock The encrypted code structure. Do not knowing in the situation of password, and though anyone with prize, saw, cut, the means such as brill all Lock can not be opened. Its theftproof performance is good, and high safety is a kind of update of existing bicycle lock Product.
