Description

The latch hook offset is moulded the magnetic theftproof lock

Technical field

The utility model relates to theftproof lock, particularly relates to the latch hook offset and moulds the magnetic theftproof lock, is mainly used in various locks (as bicycle, electric motor car, motorcycle etc.), also can be used for padlock, door lock etc.

Background technology

The kind of locks such as existing bicycle, electric motor car, motorcycle is a lot, for example crab claw lock, steel wire lock, cylinder lock etc., and the shortcoming of its crab claw lock and cylinder lock existence has: the one, easily by steel disc tamper tools such as (key shapes); The 2nd, the mutual opening rate height; And steel wire lock is cut off easily, and is dangerous equally.Another kind of lock such as coded lock, but cipher lock can be felt by light, the double infection of veteran when rotating again or sound is decoded, opened.Therefore, existing lockset (referring in particular to existing bicycle lock etc.) ubiquity shortcomings such as theftproof performance difference.Therefore, the inventor has developed Electromagnetic anti-theft lock, and has applied for that (patent No. is: 200620147917.5), its structure is to be shaped on the pellet shot from a slingshot hole in lock core shell to Chinese patent, on the lock core wall, be shaped on bullet groove, in pellet shot from a slingshot hole and the bullet groove magnetic bullet is installed, is shaped on key in lock core, key matches with key, magnetic links is installed in the key, magnetic links is corresponding with magnetic bullet, and lock core drives latching device, and latching device matches with lock bolt.Because the key of this Electromagnetic anti-theft lock does not directly contact with magnetic bullet in the lock core shell with lock core, but utilizes magnetic to inhale mutually, so can't pry open with foreign matters such as iron plate (master key), theftproof performance is good; Because the magnetic bullet capacity of arranging in lock core and lock core shell is big, but and magnetic bullet phase suction row (S, the N utmost point or N, the S utmost point) or the arrangement that repels each other (N, the N utmost point or S, the S utmost point), so mutual opening rate is extremely low.But the groove of existing Electromagnetic anti-theft lock lock bolt head is shaped on inwall, and groove cooperates with latch hook is positive, and key inserts and promotes to drive latch hook behind the lock core, and lock bolt is opened, and therefore, in a single day lock bolt is subjected to producing the bump latch hook after the powerful impact force overleaf, cause automatic jumping lock.

Summary of the invention

The purpose of this utility model is in order to solve the difficulty of processing that prior art exists, provide a kind of by changing latching device, the direction of motion of latch hook is rotated by flexible the becoming around the lock body outer wall of axial linear, thereby the groove of lock bolt head is matched with postrotational latch hook, make the lock bolt back side be subjected to external impacts can not clash into latch hook, avoid causing that jumping the latch hook offset of locking moulds the magnetic theftproof lock.

The technical scheme that the utility model latch hook offset is moulded the magnetic theftproof lock is: a lock body is arranged, lock body has lock housing outward, be shaped on latch hole on lock body and the lock housing, latch hole matches with lock bolt, lock core shell is arranged in the lock body, lock core is installed in the lock core shell, lock core has back-moving spring, is shaped on the pellet shot from a slingshot hole in lock core shell, is shaped on bullet groove on the lock core wall, in pellet shot from a slingshot hole and the bullet groove magnetic bullet is installed, be shaped on key in lock core, key matches with key, and magnetic links is installed in the key, magnetic links is corresponding with magnetic bullet, and the groove that it is characterized in that lock bolt is on the sidewall C of head direction; One side outer wall of latch hole is shaped on swivelling chute, and the lock body outer wall is shaped on loose slot, and motion bar is installed in the loose slot, and of motion bar contacts with lock core; Guide pad contacts with the other end of motion bar one of lock body, between guide pad and the lock body latch hook is housed through connector and the fastening guide pad of torsion spring, and latch hook extends in the swivelling chute of lock body outer wall, and matches with the sidewall notches of lock bolt.

Latch hook offset of the present utility model is moulded the magnetic theftproof lock, compared with the prior art, mainly be to have changed latching device, the direction of motion of latch hook (is promptly had latch hook and makes axial linear movement by lock core through the push rod drive by axial linear is flexible, it is axially vertical with lock body that the groove of the lock bolt head that cooperates with latch hook is positioned at the front surface A direction) become around the lock body outer wall and rotate, thereby the head side wall groove C direction of the lock bolt that matches with latch hook is cooperated, after lock bolt back surface B direction is hit power, can not clash into latch hook, avoid jumping lock.Its releasing process is such: the magnetic key that will match inserts the key in the lock core, make all pellets shot from a slingshot enter lock core shell, key drives lock core and promotes guide pad through motion bar, because the effect of torsion spring makes the guide pad rotation, guide pad drives latch hook, make latch hook break away from the sidewall notches of lock bolt head, at this moment lock is opened.Need not key when shutting, as long as lock bolt is inserted latch hole, back-moving spring resets lock core, and lock core snaps in the groove of lock bolt head latch hook through motion bar, guide pad, and is easy to operate.

Latch hook offset of the present utility model is moulded the magnetic theftproof lock, and one of its guide pad is shaped on the guiding skewback, and one of motion bar is shaped on corresponding inclined-plane, and the inclined-plane matches with the guiding skewback, and the inclined-plane contact area is big, and transferring power is reliable.Its guide pad inboard is shaped on locating slot, and latch hook is fixed in the locating slot, when lock core when motion bar drives the guide pad rotation, guide pad just drives latch hook and rotates together.The both sides up and down of its lock core shell are shaped on chute respectively, and the lock body inwall is shaped on sliding muscle, and sliding muscle matches with chute, when promoting key, lock core is slided steadily and be linear, thereby guarantee the latch hook rotation reliably, prevent to clash into lock housing.
