Description

Permanent magnet lock for motorcycle

The utility model relates to a kind of permanent magnetism theftproof lock, the theftproof lock that specifically a kind of motorcycle is used.

The lock of using on the motorcycle is varied at present, but some shortcomings of ubiquity.Because these locks mostly are the copper marble locks, so its mutual opening rate is higher, key easily by imitated, easily opened by foreign matter by tapered end.And the pellet shot from a slingshot of the teeth of key and lock often opens the back and produces wearing and tearing, and its life-span is reduced.What these lock employings were arranged again all is double lock bar, uses inconvenience, and manufacture difficulty is big, and theftproof performance is limited.The inventor once disclosed a kind of " permanent magnetism safety lock " patented technology in Chinese patent 92239266.8, the utility model is improved to improve and design on the basis of this patent.By the retrieval to domestic patent documentation, finding has one piece of Chinese patent 89221666.2 " multipurpose bicycle theftproof lock ", and document introduction also can be used on the motorcycle.But its structure is to be connected by retainer ring and chain and antitheft thing, and the lamp yoke of antitheft thing and front tile cover also need be made relative change and could use.

The purpose of this utility model provides the hanging permanent magnetism theftproof lock of a kind of list.Use this lock need not change the structure that has motorcycle now, and lock body is solid, firm, the life-span is long, the structure of its tapered end is simpler, and is easy to use.

The purpose of this utility model is to be realized by following proposal: the permanent magnetism theftproof lock and the tapered end thereof that are made of the tapered end on lock housing body and the lock housing body and key, magnetic marble, locking bar, teeth groove, dead bolt.On the lock housing body through hole is arranged, be processed with teeth groove on the locking bar and stretch in the through hole of lock housing body.The permanent magnetism tapered end of band flexible lock core is housed on the lock housing body.On the lock housing body retainer plate is arranged, the relative halfround bar slice that is connected with retainer plate.

Compared with the prior art the utility model has improved the theftproof performance of lock for motorcycle, more safe and reliable, and the life-span is long, and cost is low.

Below by accompanying drawing the utility model is elaborated:

Fig. 1 is the structure chart (wherein tapered end is 92239266.8 permanent magnetism safety lock) of this lock

Fig. 2 is the vertical view of Fig. 1

Fig. 3 is the locking bar position view when not locking car

Fig. 4 is lock head structure figure

Fig. 5 is the A-A sectional view of Fig. 4

Fig. 6 is Key structure figure

Among the figure: 1-lock housing body 2-tapered end 3-key 4-anti-drilling sheet 5-halfround bar slice 6-steady pin 7-holddown groove 8-locking bar 9-teeth groove 10-dead bolt 11-retainer plate 12-spring 13-tapered end 14-flexible lock core 15-magnetic marble 16-latch bolt 17-spring 18,18 '-22-hole, 21-hole, 20-tapered end hole, hole

Retainer plate 11 is arranged, the relative halfround bar slice 5 that is connected with on the lock housing body with retainer plate.Halfround bar slice fixes on an end of motorcycle one side front fork with locking, from the vertical direction of motorcycle opposite side front fork locking bar 8 is inserted the lock housing bodies again.Hook on the locking bar 8 is hooked on another front fork.One end of locking bar is processed with teeth groove 9, stretches in the through hole of lock housing body when the lock car, when adjusting locking bar to latched position, can transfer to key (3), dead bolt 10 is pushed in the teeth groove by spring 12, and this hour locking lever has been played the effect of locking Motorcycle Front Fork and front-wheel by locked.Take out locking bar in the time need not locking car after it is vertically inserted in lock housing orifice 21, there is groove 21 inboards, hole, cooperate with steady pin 6, rotate with steady pin 6 fixing not allowing locking bars.Block holddown groove 7 with dead bolt 10 and do not allow locking bar move axially, play the fixed effect of often unblanking.Locking bar adopts Technology for Heating Processing to improve case hardness.

The tapered end 2 of band flexible lock core 14 is housed on the lock housing body.Adorn flexible lock core in the tapered end 13 in the tapered end.Flexible lock core has oblique tongue 16.All be processed with the

hole

18 and 22 of arranging on flexible lock core and the tapered end, the magnetic marble 15 of different magnetic poles is housed in the hole by permutation and combination method.Spring 17 is housed between flexible lock core and the tapered end.Tapered end hole 20 is on tapered end 13 and perpendicular with hole 18.Locating to be equipped with anti-drilling sheet 4 near above the tapered end.Magnetic marble 15 can be adorned many or dress lacks, and the embodiment among Fig. 5 has adorned 5 magnetic marbles.The arrangement of magnetic marble can be arranged in the hole 18 by magnetic pole modes such as NNSSS or SSNNS.Key 3 is a sheet, be processed with on it with tapered end and flexible lock core on corresponding hole 18, hole ', hole 18 ' middle correspondence be equipped with magnetic marble 15 ', the quantity of magnetic marble is also identical with magnetic marble number in the tapered end, pole arrangement is also identical.After key inserts tapered end hole 20, just can magnetic marble 15 be scolded flexible lock core 14, in the hole of retraction tapered end like this according to principle of same-sex repulsion.Then one push away in tapered end with key again, make oblique tongue 16 drive dead bolt 10 compression springs 12 in the lock housing bodies, separate, lock can be opened with the locking bar teeth groove, and then the extraction key.Flexible lock core is by spring 17 pushed home.At this moment the magnetic marble in the tapered end is owing to be that symmetry is inhaled assembling mutually, blocks flexible lock core again and do not allow it leave so suck back mutually, played the purpose that locks.

Anti-drilling sheet 4 is used for preventing that drill bit from entering the pellet shot from a slingshot that destroys tapered end in the tapered end hole.

The utility model has been owing to adopted single hanging locking bar, and movable lock core is not only easy to use, and can prevent group, anti-drilling, prevent pounding. It is little to have wearing and tearing, and the life-span is long, and cost is low, and foreign matter is difficult to the advantages such as unlatching.
