Description

Anti-theft lock for bicycle

The utility model relates to anti-theft lock for bicycle, and the vehicles such as being used for locking bicycle, motorcycle, tricycle, trolley of more clearly saying so is in case steal security personnel's anti-theft lock for bicycle.

The anti-theft lock for bicycle in past has Steel wire rope lock, and chain lock is arranged.One end of wire rope or chain is fixed on the lock body, and wire rope or chain can not rotate with respect to lock body, to avoid during use turning round strength and inconvenient flexibly.Its lock core becomes then to be connected with stop two systems, processing technology complexity, manufacturing cost height.Stealer is easy to steal vehicle, the anti-stealing safety poor performance from the pellet shot from a slingshot blind patch destruction lock body of starting with.In addition, lock body is mostly with the cast aluminium manufacturing, and the outside does not clad thing, easily pollutes hand and makes its blackout.

The purpose of the utility model anti-theft lock for bicycle is to overcome above-mentioned shortcoming and defect, provides a kind of anti-stealing safety performance good, and flexible during use, processing and manufacturing is simple, and cost is low, does not pollute the hand clean hygiene, the anti-theft lock for bicycle that security performance is good.

In order to achieve the above object, the utility model anti-theft lock for bicycle is realized with following structure.It is by same number of tack pellet shot from a slingshot, marble spring, blind patch are installed in several holes, the lock body of alignment pin and back-moving spring is installed respectively in other two holes, be installed in the lock body y direction and have lock core with the identical round end one to one of flat nose subnumber order pellet shot from a slingshot, stop with the lock core one, be inserted in the key in the lock core, an end and the lock body end other end that is connected has the wire rope that can insert in the tapered end transverse holes with the plug of locking and is constituted.The wire rope outer cover plastic sheath, health attractive in appearance.An interstage sleeve that has shoulder block is being fixed with steady pin in the lock body end, one end of wire rope is being riveted the protruding cover that has convex shoulder, and the convex shoulder of protruding cover is installed in the shoulder block inboard of interstage sleeve, thereby wire rope is freely rotated with respect to lock body, do not turn round strength during use, convenient, flexible.

Lock core and stop are one.That is to say that the lock core end is exactly a stop.This structure manufacturing processing technic is simple, saves pin and connects or staking process, has reduced cost.This anti-theft lock for bicycle lock body outside is cladding an injection-moulded plastic cover.This has three benefits.The one, increased anti-stealing safety, stealer must at first destroy the injection-moulded plastic cover could further destroy lock body.The 2nd, health has avoided aluminium lock body to dye evil backstage manipulator portion.The 3rd, attractive in appearance beautiful.

During use, the wire rope plug is inserted in the lock body transverse holes, plug is blocked and can lock by stop after along the stop wedge surface the push-jump low-angle of stop being headed into, and this moment, key should insert in the lock core.Stop resetting after by a push-jump angle is to promote by back-moving spring, and this is a prior art.During unlatching, be rotated in a clockwise direction an angle with key, stop is rotated in a clockwise direction by key, enters plug circular cone body after pushing the wire rope plug open, and wire rope just can be drawn out of unlatching.Lock core is to stipulate that by the alignment pin end of inserting in the lock core groove this also is a prior art by the angle of key turns.

The task of the utility model anti-theft lock for bicycle comes to this and finishes.

The utility model anti-theft security performance is good, and is flexible during use.Wire rope can rotate freely with respect to lock body, does not turn round strength.Its processing technology is simple, is difficult for dying evil backstage manipulator portion, health attractive in appearance, and cost has reduced by 5～10%.The utility model lock core vertically inserts from lock body, and the use marble amount can be more than five groups, and the tooth number of key can have more than 1024 kinds, and effectively tooth number can be more than 900 kinds, and the probability of opening is very little automatically, good confidentiality.The utility model can be widely used in bicycle, tricycle, motorcycle, arrange in the anti-stealing safety of car, rickshaw and other vehicle.

Below in conjunction with accompanying drawing the utility model is done further explanation.Fig. 1 is a structural representation of the present utility model.Among the figure, have 6,5 blind patch 7 of 3,5 marble springs of 5 tack pellets shot from a slingshot in 5 pellet shot from a slingshot holes in the lock body 4, in two holes alignment pin 9 and back-moving spring 10 are installed in addition.Have 5 round end pellets shot from a slingshot 8 in the lock core 2, inserting key 1, stop 17 is made one with it.Interstage sleeve 12 is being fixed with steady pin 13 in lock body 4 ends.Wire rope 15 1 ends are being riveted protruding cover 16, and there is plastic sheath 14 outside.Protruding cover 16 is installed in interstage sleeve 12 inboards.The plug 11 of wire rope 15 inserts in lock body 4 transverse holes, locking.Lock body 4 outside claddings are shown loving care for and are moulded plastic sheath 5.

Horizontal section schematic diagram when Fig. 2 is the utility model locking.Among the figure, injection-moulded plastic cover 5 is cladding lock body 4, and the plug 11 of wire rope 15 has inserted in the transverse holes of lock body 4, is blocked by stop 17, and back-moving spring 10 withstands stop 17.

Fig. 3 is the schematic diagram of the utility model lock core 2.Stop 17 is made into integration with it.

Embodiment of the present utility model is as follows.A kind of anti-theft lock for bicycle is made of lock body, lock core, key, tack pellet shot from a slingshot, marble spring, blind patch, alignment pin, back-moving spring, wire rope etc.The lock core end is a stop, is made into integration.The outside cladding of lock body injection-moulded plastic cover.Wire rope one end has protruding cover, is installed in the interstage sleeve of lock body, thereby free to rotate, other end plug can insert the lock body locking.The present embodiment anti-stealing safety is good, and easy to use flexibly processing is simple, and cost has reduced by 10%, and security performance is good, and effectively tooth number is more than 900 kinds, health attractive in appearance.Can be widely used in the locking anti-stealing safety of vehicle such as bicycle, motorcycle, tricycle, rickshaw even the folding door that stretches.
