Description
The utility model relates to a kind of vehicle body fittings, the anti-theft security lock of especially a kind of power assist vehicle, bicycle.
Power assist vehicle, bicycle are urban and rural residents' vehicles of common of going out, and be stolen in order to prevent vehicle, is typically equipped with theftproof lock.At present, the better safety performance theftproof lock has the ring gear lock.It is formed by combining by tapered end, lock core, gear, tooth bar, locking bolt, lock housing.During use key inserted in the lock core hole and rotate, handsetting gear rotates thus, and the tooth bar of gear driven and its engagement moves, and makes the locking bolt that is connected with the tooth bar end outwards mobile, enters in the hole of the lock housing other end until locking bolt one end, promptly locks.When needing to open, key is pressed rightabout and is rotated, and makes locking bolt return to original position, and lock is promptly opened.The lock core of this lock adopts the billiards structure form usually, damages easily; Key is the single cog form, can only the one-sided use of direction; The keyhole of lock core opens wide, and enters dust etc. easily.All these are made troubles to use.In addition, tapered end has the form of structure of upper and lower covers, is prized easily; Tooth bar and locking bolt lack anti-fault mechanism, may cause to come off and lose anti-theft feature.
The purpose of this utility model is improved existing anti-theft lock for vehicle, and it is better to propose a kind of theftproof performance, uses vehicle anti-theft safety lock more easily.
The vehicle anti-theft safety lock of the utility model design is made of tapered end, lock core, gear, arc-shaped rack, locking bolt, annular lock housing, and its structure as shown in Figure 1.Wherein, gear and lock core are installed in the tapered end 2, arc-shaped rack 3 outer ends and locking bolt 4 inner fixedlying connected, and be installed in the annular lock housing 1.In the utility model, lock core is designed to special locking plate form of structure, and is shown in Figure 4 as Fig. 2 one.Lock core 5 likeness in form cylinders, centre be lock core hole, i.e. keyhole, there are 5 horizontal locking plate hole slots 7 the keyhole both sides of lock core, 5 locking plates 11 of confession placement, position symmetry.Corresponding, the form that also is designed to the double cog symmetry of key 20.Like this, when opening lock, need not debate other lobe direction,, bring convenience to use as long as be inserted into lock core hole to key.The front end of lock core has a square opening, is provided with a valve 17 in this hole, and a side of this valve 17 is fixed in the square opening of lock core front end by a torsion spring 18, and in nature, this valve covers lock core hole.When key inserts, valve to be pushed open, valve promptly overturns downwards around the torsion spring of its side, and key promptly inserts lock core hole; When key was transferred to, valve returned to the origin-location under the effect of torsion spring elastic force, and lock core hole is covered, and can avoid extraneous dust etc. to enter in the lock core hole.Above-mentioned lock core 5 is installed in the lock core shell 6.The inwall of lock core shell 6 corresponding to the position axis of the locking plate hole slot of lock core two sides to having locating slot.When pin sheet hole slot 7 rotated position on the lock core 5 arrived the locating slot of lock core shell inwall, because flexible effect, locking plate 11 promptly was stuck in the groove, thereby lock core can not be rotated, and at this moment, lock is locked state or opening.When key 20 inserted pin core hole, if the locking plate size of the lobe of key and serial and spread pattern are coincide, then lock core was rotatable, and lock promptly is unlocked.If the locking plate of the lobe of key and serial is misfitted, then lock core can not be rotated, and lock can not be opened.Promptly open different locks with different keys.
The end section of lock core of the present utility model can be designed to square pin form, and the centre bore of gear 8 matches, and gear 8 is set on the pin of lock core afterbody, the pin outside is provided with circlip groove 10 in addition, back-up ring 9 is stuck on the circlip groove 10, like this, gear 8 and lock core 5 is fixed as one.Offer a locating hole 12 at the lower end of lock core shell 6, the inside is provided with a spring and positioning bead 13, and the corresponding position of gear has a pearl shape groove.When gear 8 rotates, when the pearl shape groove on it is aimed at the locating hole 12 of lock core shell 6,, gear 8 and lock core 5 are located owing to the effect of positioning bead 13, at this moment, lock is to be opened or locked state.Lock core has and is provided with a Lock cylinder cover 16 between front end and the lock core shell 6, has keyholes in the middle of the lid 16, inserts for key.
The shell 15 of tapered end 2 of the present utility model can be designed to a garden tubular, lock core 5 places in the tapered end shell 15 together with lock core shell 6, gear 8 etc., a tubular housing 19 is set between tapered end shell 15 and the lock core shell 6, with compact package such as lock core shells in housing 19, the housing top center is offered hole, a garden corresponding to the position of Lock cylinder cover 16, inserts for key 20.Cylinder lock head capsule 15 is closely chimeric with tubular housing 19, and this kind structure can prevent that lock from being prized, and increases the safety of lock.
In the utility model, a garden shape grommet 14 is set between the bottom of gear 8 and tapered end shell 15, to supporting between gear 8, lock core 5 and the tapered end shell 15, so that fixing.
In the utility model, arc-shaped rack 3 and interior gear 8 engagements of tapered end, the front end of tooth bar 3 is fixedlyed connected with the inner end of locking bolt 4, for example fixes with rivet.The tooth bar rear end is a garden shape end socket, and the engagement of wheel and rack is so far.This structure can move spacing in addition to tooth bar, prevents that tooth bar from moving excessive and come off.Be provided with one silently 21 in lock housing one end inboard, this silently 21 can be with rubber or plastic production, can be used for spacing to locking bolt 4.
In addition, the inner end of locking bolt 4 has a locating hole 22.A spring and a locking ball 23 are set in this hole.This steel ball 23 prevents swing with the locking bolt location.
The utility model structure is science, reasonable more, and performance is safer, reliable, uses more convenient, flexible.For example, the locking plate special structure form of lock core makes the unlatching of lock, more flexible, the convenience of closure, and She Ji key becomes the double cog symmetric form thus, makes when opening lock and need not recognize the lobe direction, reduces trouble; Valve setting on the lock core can prevent that dust, rainwater etc. from entering lock core, in order to avoid unlatching, the closure of influence lock; Being provided with etc. silently in the position limiting structure of tooth bar rear end, the locking ball of locking bolt and lock housing one end can prevent that tooth bar and locking bolt from coming off, swinging and lose anti-theft feature.
The vehicle anti-theft safety lock of the utility model design can be widely used in bicycle, the power assist vehicle of various models.
