Abstract

The utility model relates to a no-hole magnetic lock with two purposes of a common lock and a cipher lock and the key of the magnetic lock, and the magnetic lock is composed of a lock surface, a lock sleeve, a lock core, a lock tongue and the key. One side of the lock core near the lock surface is provided with a clamping groove and a sliding end plug which is used for sealing the lock surface, the sliding end plug is connected with the bottom of the lock core by a spring, the inner side of the lock core is provided with magnetic posts which are used for clamping the lock core and the lock sleeve, and a cipher disk is arranged on the lock surface. The key forms a cross rib shape, the upper side of each rib is provided correspondingly with the magnetic posts, and the magnetic lock can be used as a cipher lock by dialing the cipher disk. The cipher can also not be added, and older adults and children can use conveniently. Because the utility model is provided with the sliding end plug, the lock surface has no hole, the key can have no repeated types according to the changes for the position and the polarity of the magnetic posts, and the operation is safe.

Description

Common and dual-purpose unpreforated magnetic tape tapered end of password and key

The utility model relates to a kind of lock and key, particularly a kind of coded lock and key that adopts magnetic principles, and specifically a kind of common and password are dual-purpose, atresia, magnetic padlock head and key.

Existing traditional cylinder lock major part is porose, easily stops up, and key has double wedge easy to wear and fracture, other people also can open the door after the key loss, and existing coded lock does not have private key, and only by password unlocking, though the coded lock of available alternative when key arranged, but the key that is equal to nothing, its key only play the effect of combination disk handle, in case password is given away secrets, will cause any property loss, the unlocking coded lock complexity that has, old man and children are difficult for grasping, and difficulty is big when unblanking.Though existing atresia coded lock has been broken the general layout of traditional locks, lost traditional locks characteristics easy for installation, complex structure, and be square, ulking thickness is excessive, is installed in the outside and is easily pounded by sled. more

The purpose of this utility model is to overcome above-mentioned defective, thereby a kind of advantage that keeps traditional locks is provided, and is simple in structure, can make common lock and coded lock dual-purpose atresia tapered end and key.

The purpose of this utility model is achieved in that the utility model is made up of locking face (1), lock tube (5), lock core (4), dead bolt (7) and key (8), and wherein: lock core (4) is provided with the sliding plug (3) of a band draw-in groove and sealing locking face (1) by locking face (1) one side; Sliding plug (3) links to each other with lock core (4) bottom by back-moving spring, the horizontal section of sliding plug (3) is " ten " font, be provided with the magnetic post (6) that can block lock core (4) and lock tube (5) in the hole of lock tube (5), be connected by spring bottom the magnetic post (6) with between the lock tube (5), locking face (1) is provided with four combination disk (2), and the draw-in groove size of the breach of combination disk (2) and sliding plug (3) adapts; The cross protruding school shape of key (8) head for adapting with sliding plug (3), the afterbody of key (8) is the screwdriver shape, and each school of key (8) is provided with two corresponding magnetic posts in magnetic post (6) position with lock core (4) lining.

The utility model is simple in structure, utilizes magnetic principles, can do common lock and use, can make coded lock again and use,, make the locking face atresia owing to be provided with sliding plug, can be anti-blocking, pick-proof, anti-pounding, rely on the change in location of magnetic post and the variation of the N utmost point S utmost point can make key not same, safe and reliable.

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

State diagram when Fig. 1, Fig. 2 are the utility model locking.

Fig. 3 is locking face figure.

Fig. 4, Fig. 5 are the utility model unlock operation state diagram.

Locking face (1) is approximate with the traditional locks size, four notched circular combination disk (2) are arranged on it, can block the sliding plug (3) of band draw-in groove and seal locking face, make the locking face atresia, can prevent that foreign matter from entering lock inside, chamber, thereby reach anti-blocking, preventing universal key and lose key after other people unblank, when unblanking, the afterbody that utilizes key (8) to be the screwdriver shape is stirred combination disk (2) by the code number number, make the breach of combination disk (2) relative with the draw-in groove of sliding plug (3), key this moment (8) can promote sliding plug (3), compression reseting spring (9) is to lock core (4) bottom, eight magnetic posts on four ribs of key (8) head are corresponding with eight the magnetic posts (6) that block lock core (4) and lock tube (5), under the principle effect that the same sex is repelled each other, make eight the magnetic posts (6) that block lock core (4) and lock tube (5) compress spring separately, be retracted in the hole of lock tube (5), thereby lock core (4) separates with lock tube (5), and key this moment (8) can freely rotate, and finishes the action of unblanking.

Open action finish after, key is got back to original position, magnetic post (8) stretches in the hole of lock core (4) under spring action, blocks lock core (4) and lock tube (5) again, key does not withdraw from then from original position and pulls out, and the effect of " general does not get down from horse " is promptly arranged.

If have old man and child to unblank in the family, encrypted code not just, private key (8) jacking sliding plug (3) can open the door, lock.

In the time of need accessing to your password, the afterbody that available key (8) is the screwdriver shape is arbitrarily stirred four combination disk and can be added password, and key (8) can not arbitrarily be inserted.
