Description

Magnetic core lock for bicycle

The utility model relates to a kind of for bicycle lockset.

The for bicycle shape of a hoof lock of Xiao Shouing in the market, its lock body all are that monnolithic case is single through the iron plate punching stretch forming, and changeability is poor; Lock core adopts pellet shot from a slingshot, blade construction or tube spoon lock core structure, and the lock of former structure easy stolen car person open with foreign matter, so antitheft confidentiality is poor, although the latter changes tube spoon lock core structure into by the chip lock core, but the processing technology complexity, cost is corresponding higher, is not suitable for common people's shopping psychology.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, but provides a kind of lock body one-shot forming to process the Magnetic core lock for bicycle of easy and tool high security.

The utility model is realized by following measure:

Magnetic core lock for bicycle mainly is to be made of the lock body of one-step die casting, lock bridge and lock core, quiet core in the lock core and the commentaries on classics core corresponding with it have at least in a pair of pellet shot from a slingshot hole and are provided with the magnetic core pellet shot from a slingshot, change the pellet shot from a slingshot hole that core is equipped with the magnetic core pellet shot from a slingshot and locate to be equipped with the magnetic core pellet shot from a slingshot corresponding on the key.

The pole arrangement of quiet core pellet shot from a slingshot hole inner magnetic core pellet shot from a slingshot is N-S, and the pole arrangement of changeing core pellet shot from a slingshot hole inner magnetic core pellet shot from a slingshot is S-N.

Among the figure: 6 assemblings of 1 lock bridge, 2 lock bodies, 3 beam springs, 4 assembling band pads, 5 bottoms are with 7 dead bolts, 8 tongues, 9 shifting blocks, 10 jump rings, 11 quiet cores 12 to change core 13 magnetic core pellets shot from a slingshot 14 keys 15 lock cores 16 key magnetic core pellets shot from a slingshot

Below in conjunction with accompanying drawing the utility model is described further:

Magnetic core lock for bicycle is the lock body 2 by one-step die casting, formations such as lock bridge 1 and lock core 15, lock core 15 comprises quiet core 11, change core 12, with change core one end and be movingly shifting block 9, tongue 8 and dead bolt 7, quiet core 11 and the commentaries on classics core 12 corresponding with it have at least in a pair of pellet shot from a slingshot hole and are provided with magnetic core pellet shot from a slingshot 13, the pole arrangement of quiet core pellet shot from a slingshot hole inner magnetic core pellet shot from a slingshot is N-S, the pole arrangement of changeing core pellet shot from a slingshot hole inner magnetic core pellet shot from a slingshot is S-N, magnetic core pellet shot from a slingshot 16 is located to be equipped with in the pellet shot from a slingshot hole that corresponding commentaries on classics core is equipped with the magnetic core pellet shot from a slingshot on key 14, the pole arrangement of this magnetic core pellet shot from a slingshot is N-S, beam spring 3 one ends are fixed in bottom righthand side in the lock body, its other end and lock bridge are connected and fixed, bottom 5 is fastening by rivet and lock body, is arranged with the assembling that is used to install lock and is with 6 and assembling band pad 4 on bottom 5.

When Magnetic core lock for bicycle is in locking states, as shown in Figure 3, because magnetic core pellet shot from a slingshot 13 is under the effect of homopolar-repulsion power, quiet core 11 inner magnetic core pellets shot from a slingshot are distributed in bottom, pellet shot from a slingshot hole, change and also be in a quiet core pellet shot from a slingshot hole part when core 12 interior magnetic core pellets shot from a slingshot are distributed in bottom, commentaries on classics core pellet shot from a slingshot hole, promptly changeing core can't rotate, and the lock core locking makes it to be in locking states.

When opening this Magnetic core lock for bicycle, as shown in Figure 4, when changeing core 12 with key 14 contacts, the magnetic core pellet shot from a slingshot in the key is under the effect of homopolar-repulsion power, and the magnetic core pellet shot from a slingshot that just changes in the core pellet shot from a slingshot hole moves back in quiet core pellet shot from a slingshot hole, and make it to place in the middle of quiet core magnetic core pellet shot from a slingshot and the key inner magnetic core pellet shot from a slingshot, this moment key, shifting block 9 is stirred dead bolt 7, dead bolt compression tongue 8, and withdrawing from lock bridge 1 groove, lock is promptly opened.

The utility model has the advantages that lock core adopts magnetic core billiards structure, the principle opened lock of applied magnetic homopolar-repulsion Tool is accomplished to reduce cost at simplified processing process simultaneously, and can be prevented the foreign matter unlatching, so the confidentiality that should lock Be the desirable lockset that bicycle lock is regenerated by force.
