Abstract

The utility model relates to a turning type anti-theft lock for bikes, which is composed of a lock core, a lock sleeve and a lock block; the lock sleeve is sheathed in the front part of the lock core, the lock block is sheathed in the front part of the lock core, and the lock block and the lock core are fixed by screws; a lock is installed on a long hole of a front fork of a bike and a casing tube; when long hole of a front fork of a bike and a casing tube is dug, the front fork and the casing tube are correspondingly rotated 30 DEG to 60 DEG and the hole is dug; when a bike is locked, the bike can not be ridden but the bike can only rotate; a stealer who steals the bike can not open the lock and takes away the bike by riding.

Description

Turning of bicycle formula anti-theft column lock

The utility model relates to a kind of turning of bicycle formula anti-theft column lock, during this lock car, makes front-wheel rotate an angle, is called steering lock fixed pattern anti-theft column lock, belongs to the bicycle accessory scope.

The locking of bicycle is at present all adopted and on the bicycle external frame lockset is installed and is realized locking.In the recent period at the bicycle theft-prevention problem, although very big effort is all done by bicycle lock factory, intensity, the form of lockset all there has been very big improvement,, the pick-proof problem is not solved all the time.Because the locking of bicycle at present, it all is locking to wheel, so having, used lockset all is installed on the bicycle external frame, outside lockset all is exposed to, be bright lock, be easy to cause artificial outside destroy, antitheft effect is poor, so bicycle is stolen serious, its major cause is all destroyed lockset and is formed.

The purpose of this utility model, exactly in order to address this problem, the locking wheel formula that 1. changes in the past is locking wheel steering formula, thereby effectively stops the cruising of bicycle; 2. change the bright lock mode that is installed on the external frame for transplanting, make external force be difficult to destroy in bicycle pipe support in-to-in built-in lock form.

The purpose of this utility model is achieved in that

1. anti-theft column lock is made up of lock core 1, lock tube 2, lock dog 3, earlier lock tube 2 is inserted in lock core 1 front portion, lock dog is inserted in again with screw lock dog and lock core is fixed then, and lock core and lock tube are to rotate to connect, lock core and lock dog spline fitted, and be screwed.

2. need on bicycle front fork and sleeve pipe, to open a slotted hole, anti-theft column lock is installed in the slotted hole of front fork and sleeve pipe.

3. when the bicycle front fork sleeve pipe is dug slotted hole, earlier front fork and sleeve pipe are relatively rotated 30～60 degree, punching then.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 Fig. 2 is lock core figure, and as shown in the figure, the lock core right-hand member is a cylinder, and the middle part is six prisms, and left end also is a cylinder.

Fig. 3, Fig. 4 are lock dog figure, and as shown in the figure, there is hex hole at the lock dog center, and it cooperates with lock core.

Fig. 5, Fig. 6, Fig. 7 are lock tube figure, and circular hole cooperates with lock core left end cylinder in the middle of the lock tube.

Fig. 8 is lock core, lock tube, lock dog assembling stereogram, and the lockset after the assembling is installed in the slotted hole of bicycle cutting.

Fig. 9 is bicycle processing pass figure, promptly when bicycle front fork and sleeve pipe cutting slotted hole, earlier front fork and sleeve pipe is relatively rotated 30～60 degree, punchinges then.

Figure 10 is a lockset turnover constitution diagram, and at this moment, front fork and sleeve pipe still can go out to rotate certainly, do not hinder bicycle running.

Figure 11 is lockset lock-out state figure, and at this moment front fork and sleeve pipe have rotated 30～60 degree, and lock dog blocks in the slotted hole of digging.Front fork and sleeve pipe can not freely rotate, this lock creation characteristics that Here it is.

Figure 12 is the lock dog block diagram of another kind of lockset, and profile is half-moon-shaped centre a cross bore, and it cooperates with lock core.

Figure 13 is the assembly drawing of lock core and lock tube, and lock dog is not directly installed on the lock core.

Figure 14 is bicycle front fork and sleeve pipe processing pass figure.

Figure 15 is bicycle lock opening figure.

Figure 16 is bicycle lock lock-out state figure.

Its principle of work:

Earlier at lock pipe of the bottom of bicycle front fork and front fork sleeve pipe processing, lock dog is installed on the front fork tube inwall of slotted hole opposite, at this moment the elongated hole on the lock dog intersects at elongated hole 90 degree on front fork and the sleeve pipe, lockset inserts along collar aperture, at this moment lock core column's bolt is parallel with slotted hole on the lock dog, can go out to extract out certainly, lock tube at this moment and lock core play the effect of lock, and front fork and sleeve pipe are pinned.Turn 90 degrees when car key revolves, lock core rotation, the post bolt that is installed in the lock core rear portion also revolves and turn 90 degrees, and perpendicular to the aperture on the lock dog, lockset can not be extracted out, at this moment the lock core shell hole align with the lock tube shell hole, the car key extraction, turning of bicycle is thoroughly pinned.During unlatching, revolve again with car key and to turn 90 degrees, at this moment the post bolt of lock core rear end goes out perpendicular to the lock dog small pore-like to become parallel aperture, can come in and go out, and lock core shell hole and the dislocation of lock tube shell hole, car key lockset is relatively extracted out, together extracts out together with lockset when extracting key out, lock subsolution between bicycle front fork and sleeve pipe is removed, and bicycle is got back to free steering state.

The advantage of this steering-type theftproof lock:

1. the lock installation is hidden, is difficult for lockset is pried open.

2. after the lockset locking, front fork and sleeve pipe have relatively rotated an angle, and bicycle can only be turn-taked can't Advance.

Claims (1)

1. turning of bicycle formula anti-theft column lock, form by lock core 1, lock tube 2, lock dog 3, it is held to levy and is, earlier lock tube 2 is inserted in lock core 1 front portion, then lock dog is inserted in again and lock dog and lock core is fixed with screw, lock core and lock tube are to rotate to connect, lock core and lock dog spline fitted, and be screwed.
