Description

Code clock for bicycle

The utility model relates to a kind of bicycle theft-prevention coded lock, belongs to the technical field of bicycle accessory.

Bicycle is still domestic city resident's the main vehicles, but owing to have no suitable place, thereby the situation of lost vehicles is more, general bicycle lock does not have the effect of pick-proof and anti-theft simply, leaves behind key sometimes, just be difficult to unblank, also bring many troubles, these demand urgently improving.

The purpose of this utility model is that a kind of bicycle theft-prevention coded lock will be provided, it can overcome above-mentioned shortcoming, utilizes the mechanical code lock locking, need not carry key, as long as remember password figure, just can unblank, use easylier, especially use car night, the light dark, can stir the switch of illuminating lamp, can the recognition code numeral, can blindly not stir number.

The purpose of this utility model is achieved in that U font lock frame upper right quarter fixes a jump ring with rivet, left part is fixed an illuminating lamp with rivet, the lower-left end is fixed a fixed cover, coded lock lock frame bottom righthand side is housed in the cover fixes a rotation condom interpolation with rivet and adorn a locking bar, the locking bar right-hand member is connected with one handle.The jump ring left end is porose, and the left-end flat right-hand member bends to～shape.Fixed cover is the ┍ font, and upper right side has 2 holes, and it is tubular that the lower-left end curves the garden.The porose lower knuckle in rotary sleeve top becomes the garden tubulose.The lock frame is the U font, and the lower-left end has 2 holes, and slotted hole is arranged at top, and bottom righthand side is porose, and also there is slotted hole the top, and lock frame upper right quarter has a hole in addition, and middle position also has a hole.The lock body left end of coded lock is a Cylinder, has step the right that 4～5 digit wheels are housed, and there is a numeral in the numeral 1～9 on the dead slot surface of wheel.The core pipe of packing in the lock body, a side has breach, and the digit wheel end face has recessed garden connected in star, and bottom land has the hole, garden, and a side in hole has breach, back-up ring is housed in the groove is locked on the core pipe with snap ring.The copper Cylinder left end of pin rod fuses with the shoulder that has the rectangular lock core of zigzag, but the Cylinder right-hand member of locking bar is connected with a projection socket one handle.Lock frame right part has aperture, connects a long-chain in the hole, and the end of the chain has the garden ring.

Now in conjunction with the accompanying drawings the structure of bicycle theft-prevention coded lock is described in detail:

By Fig. 1, the lock frame (1) of coded lock is the U font, upper right quarter is fixed a jump ring (2) with rivet, left part is also fixed an illuminating lamp (3) with rivet, the lower-left end is fixed a fixed cover (4) with rivet, coded lock (5) is housed in the fixed cover (4), U font lock frame (1) bottom righthand side is fixed a rotary sleeve (7) with rivet, insert a locking bar (6) in the cover, locking bar (6) right-hand member is equipped with handle (8), and lock frame (1) right lower quadrant has aperture (34) in addition, connect a long-chain (35) in the hole, all there is garden ring at the two ends of long-chain, and this long-chain can be around big tree or above the post beam, and the garden ring set inserts the lock body endoporus again at the locking bar upper lock core.

By Fig. 2, U font lock frame (1) lower-left end has 2 holes (8), being used for fixing fixedly, there is a slotted hole (10) top of trepanning, bottom righthand side porose (11) is used for fixing rotation trepanning (11) top also a slotted hole (12), its position is fixed in coded lock above the cycle frame with corresponding being used for of slotted hole (10), lock frame (1) upper right quarter has a hole (13) in addition, be used for fixing a jump ring (2), the central part of lock frame (1) also has a hole (14), this hole connects a password board with a cord, and numerical code expression is opened the password of this coded lock on the board.

By Fig. 3,4, jump ring (2) left end porose (15) is used for penetrating rivet, the jump ring left-end flat, and right-hand member bends to～shape.

By Fig. 5,6, fixed cover (4) is the ┍ font, and upper right side has 2 holes (16), and available rivet fixes above the end of lock frame lower-left, and the lower-left end bends to the garden tube shape, the coded lock (5) of can packing into.

By Fig. 7,8, rotary sleeve (7) top porose (17), available rivet is fixed on lock frame (1) above the bottom righthand side, and lower knuckle becomes the garden tubulose, Guan Zhongke plug-in mounting one locking bar (6).

By Fig. 9, locking bar (6) has a Cylinder, right-hand member is connected with a projection (18), but socket handle (8), fluted chimeric the linking into an integrated entity of projection (19) with another Cylinder made of copper of left end, copper Cylinder left end fuses with the shoulder (21) that has the rectangular lock core of zigzag (20).

By Figure 10, the lock body left end is a Cylinder, just in time is inserted in the fixed cover (4), lock body has a step (28), makes the lock body can slippage, and 4～5 digit wheels (22) are equipped with on step (28) right side, this takes turns a similar gear, and there is numeric character 1～9 on its between cog groove (24) surface.

By Figure 11, the core pipe (25) of packing in the lock body, one side has a breach (26), the zigzag lock core (20) of its width and locking bar (6) adapts, and digit wheel (22) end face has a garden connected in star, and jagged (27), back-up ring (29) is housed in the groove, use snap ring (32) to be locked on the core pipe (25) again, make digit wheel (22) unlikely outwards mobile, back-up ring (29) is equally also jagged can be overlapped with the breach (27) of digit wheel (22).

Forward certain position when rotating digit wheel (22) to, the breach (27) of digit wheel (22) is aimed at the breach (26) of core pipe (25), just can pull out the lock core (20) of locking bar, should aim at top bar dots in red (23) on (28) of lock body when the predetermined cipher numeral is stirred, the correct position of this indication notch is errorless.

By Figure 12, the similar gear of digit wheel (22), its end face have a garden connected in star (33), and bottom land has the hole, garden, a side in hole jagged (27).

Can stir the digit wheel of coded lock (5) during use, make wheel go up the digital red point (23) of aiming at the left side.Lock core is spurred to the right, just can unblank, when using car night, can press the illuminating lamp (3) of lock cipher lock (5) top, make bulb shinny, just can see password figure clearly, unlikely misidentification, after locking bar moves right, can rotate around the hole of U font lock frame (1) bottom righthand side, locking bar (6) can be buckled in the jump ring (2) with parallel locking bar (6) top that is adjacent to of U font lock frame (1) right part.

As long as put down set right numeral on the coded lock of locking bar (6) during locking, push lock core left, dial random number then, at this moment lock.

Compared with prior art, Ctpher lock with burglar alarm for bicycles has following advantages:

1. without carrying keys, utilize special-purpose password figure to unblank.

2. utilize and lock light in the dark place of light night, also can see password figure clearly and unblank easy.

3. have long-chain, can be bicycle around being locked in big tree or above the pillar.
