Description

Multifunctional bicycle lock

The utility model belongs to the anti-theft lock for bicycle field.

In commercially available prod and disclosed interrelated data, the theftproof lock that multiple different types and structure are arranged, wherein be no lack of various security personnel's performances and lock preferably, but the considerable part in these locks focuses on its pick-proof lock function of reinforcement, steals rare report to how preventing that car load from being moved.

The purpose of this utility model provide a kind of not only have preferably tamper-resistant function and can be easily with car load and ground fixture is connected and fixed in case car is moved the anti-theft lock for bicycle of stealing.

The utility model is realized its purpose as follows: the tail end of locking bolt 10 is fixedlyed connected with cable wire 4, and the free end of cable wire 4 (being tail end) has a metal ring 11.Can load onto digital rotating disk 6 and 8 respectively in the upper bottom surface and the side of the bearing of locking 7 in the time that coded lock need being installed additional, the axle 15 of numeral rotating disk 6 can be vertically intersected on the concave ring groove 13 of locking bolt with locking bolt 10, pin 17, ring spring 18, spring pad 19 are housed on axle 15 in order and sell 20, the axle 24 of numeral rotating disk 8 can be vertically intersected on the concave ring groove 25 of axle 15 with the axle 15 of digital rotating disk 6, on the axle 24 pin 23 and ring spring 21 is housed.Circular hole edge at axle 15 and the axle 24 bearing shells 27 that pass has a small gap 16 and 22 respectively.

Use anti-theft lock for bicycle of the present utility model, owing to there is long cable wire to link to each other with locking bolt, can be on distance bicycle ground fixture far away such as electric pole, trees, railing, wall column etc. with bicycle lock, car load is difficult to quilt and is moved and steals; Also can pin front and back wheel simultaneously, car is difficult for being pushed away; Can also link to each other with the lock of adjacent car, neither hinder the car of unblanking to use of adjacent car, also increase the safety of two cars simultaneously.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is the outline drawing of this bicycle multifunction anti-theft lock.

Fig. 2 is the shape schematic diagram of the locking bolt 10 that fuses with cable wire 4.

Fig. 3 is that A when installing coded lock additional in bearing 7 is to sectional view.

Lock core base 2 and bearing 7 lay respectively at the both sides of lock U-shaped frame 3, and the tail end of locking bolt 10 is fixedlyed connected with the head of cable wire 4 by connector 12, and the tail end of cable wire has metal ring 11, and cable wire can be cast and pile up to save parking space when not using.For the anti-theft feature of strengthening locking, can in bearing 7, install coded lock additional, its structure is as shown in Figure 3.The axle 15 of numeral rotating disk 6 inserts in the bearing through a circular hole at bearing shell 27 upper bottom surfaces and intersects vertically at concave ring groove 13 places with locking bolt 10, pin 17, ring spring 18, spring pad 19 are housed in order and sell 20 on the axle 15, there is a small gap 16 at the edge of this shell circular hole; The circular hole that the axle 24 of numeral rotating disk 8 passes the bearing side casings inserts in the bearing, can be vertically intersected on its concave ring groove 25 with axle 15, on the axle 24 pin 23 and ring spring 21 is housed, and also there is a small gap 22 at the circular hole edge on this shell.

When using this lock, the head of locking bolt 10 is passed bearing 7 and enters the lock core that is positioned at lock core base 2 and can pin.Lock core is identical with conventional lock core.If desired with bicycle lock the fixture on ground as the tree bar on, can be earlier with cable wire 4 around the tree bar after one week, the head of locking bolt is passed the metal ring 11 of cable wire afterbody, behind the tension cable wire locking bolt head is passed bearing 7 again and enter in the lock core, bicycle promptly is lockable a wheel and is locked on the tree bar.Method can be pinned two wheels of car equally simultaneously or oneself car is connected with the lock of adjacent car and be locked according to this.When this lock need install coded lock device additional, conventional concave ring groove 14 is not only arranged on locking bolt 10, and with bearing 7 corresponding positions on a concave ring groove 13 is arranged.When unblanking, twist digital rotating disk 8 earlier, when the pin on the axle 24 23 forwards near the breach 22 on the shell circular hole edge of this slotting warp, digital rotating disk 8 and axle 24 are extracted out outward, and pin 23 is drawn out of enclosure by breach 22 with axle 24, looses one's grip after axle is rotated to an angle again, pin 23 is stuck on the unnotched position, shell circular hole limit, make axle 24 location, axle 24 promptly disengages with axle 15, and axle 15 just might axial displacement.Then turn digital rotating disk 6 again, when treating that pin 17 on axle 15 goes to the breach 16 on circular hole limit on next-door neighbour's bearing shell digital rotating disk 6 and axle 15 are extracted out together, the axle 15 and the concave ring groove 13 of locking bolt are disengaged, locking bolt 10 just can move axially, unblank with key 1 this moment again, locking bolt just can be deviate from from lock core, and whole lock is opened fully.Operating procedure is opposite when shutting, and one by one locking bolt 10, axle 15 and axle 24 is put into the position.In the time need not locking, after locking bolt withdraws from lock core and bearing fully, the locking bolt head can be folded up in folder spring 5, cable wire 4 then can be around the short tube that is placed on a saddle under, and is not only attractive in appearance but also make things convenient for.Cable wire can adopt wirerope, also can adopt iron chains or other to have the pallial siphuncle of higher-strength.Numeral rotating disk 9 mainly plays the fascination effect, and when turning this rotating disk, its axle 26 can freely rotate.
