Abstract

The utility model relates to the technical field of locksets, in particular to a magnetic lock, which is composed of a lock body, a lock core and a matched spiral key. The magnetic lock is characterized in that a spiral key hole is arranged in the lock core, and a pair of magnetic marbles are arranged in a first marble hole of the lock body, respectively a first magnetic marble and a second magnetic marble; relative surfaces of both are homopolar, and the second magnetic marble can move up and down in the first marble hole of the key body and a second marble hole of the key core; a third magnetic marble is inlaid in a marble hole which corresponds to the second marble hole of the key core on the back of the spiral key, and the third magnetic marble is homopolar with the relative surface of the second magnetic marble in the marble hole of the key core; Numbers of the first magnetic marble, the second magnetic marble and the third magnetic marble are above two groups. The magnetic lock of the utility model cannot be unlocked by a common key or a key with magnetism or other unlocking tools. Thus, the magnetic lock is safer and more reliable.

Description

A kind of magnetic lock

Technical field

The utility model relates to lock technology field, especially relates to a kind of magnetic lock.

Background technology

Along with modern social development, people are more and more higher to the requirement of confidentiality and privacy, and the tapered end of various raising confidentiality arises at the historic moment, and magnetic lock is wherein a kind of.The locking of magnetic lock and unlatching are to lean on magnetic bullet on the key to act on lock core, and magnetic bullet in the lock or irony pellet shot from a slingshot are realized.But have a deadly defect, the quantity of first magnetic bullet, second magnetic bullet and the 3rd magnetic bullet in the magnetic lock is more than 2 groups, distribution rule, and key is a bare metal rod.The principle that the thief utilizes the magnetic dot homopolarity be imbedded in key inside to repel is mutually pushed up pellet shot from a slingshot and is limited the position, thereby makes the lock core rotation remove obstacle.Therefore magnetic lock can only be locked gentleman, can not lock the person of low position, and safety has been subjected to serious challenge.

Summary of the invention

The purpose of this utility model be overcome above-mentioned technological deficiency and provide a kind of and shockproofly, anti-dial, the magnetic lock of safety.

The utility model solves technical scheme that its technical problem adopts:

A kind of magnetic lock, by lock body, lock core and supporting spiral key are formed, it is characterized in that: be provided with the spiral key hole in the described lock core, in the first pellet shot from a slingshot hole of described lock body the pair of magnetic pellet shot from a slingshot is arranged, be respectively first magnetic bullet and second magnetic bullet, both opposite faces are same polarity, second magnetic bullet can be up and down in the second pellet shot from a slingshot hole of the first pellet shot from a slingshot hole of lock body and lock core, the pellet shot from a slingshot hole that the spiral key back is corresponding with the second pellet shot from a slingshot hole of lock core is embedded with the 3rd magnetic bullet, the opposite face of second magnetic bullet is a same polarity in this magnetic bullet and the lock core marble hole, first magnetic bullet in the magnetic lock, the quantity of second magnetic bullet and the 3rd magnetic bullet is more than 2 groups, can determine that by the computer code technology magnetic bullet in magnetic lock axially and distributing position radially.

The utility model magnetic lock is to utilize magnetic phase exclusion principle at the same level, the pellet shot from a slingshot hole that the magnetic bullet of lock core is all compressed into lock body, make that nonmagnetic pellet shot from a slingshot blocks the core lock body on the lock core, make core form released state, lock core just can freely rotate, and magnetic lock is opened.

The advantage of the utility model magnetic lock is: can not be with usual key, or have the key of magnetic or other unlocking tool and open magnetic lock, make magnetic lock safer, more reliable.

Description of drawings

Fig. 1 is the sectional drawing behind the insertion spiral key;

Fig. 2 inserts the preceding sectional drawing of spiral key;

Fig. 3 is the schematic diagram in spiral key hole;

Fig. 4 is the schematic diagram of spiral key.

Number in the figure: 1. lock body, 2. lock core, 3. spiral key, 4. pellet shot from a slingshot hole, 5. magnetic bullet 6. magnetic bullets, 7. pellet shot from a slingshot hole, 8. magnetic bullet, 9. spiral key hole.10. pellet shot from a slingshot hole.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples

With reference to the accompanying drawings 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of magnetic lock, by lock body (1), lock core (2) and supporting spiral key (3) are formed, it is characterized in that: be provided with spiral key hole (9) in the described lock core (2), there is the pair of magnetic pellet shot from a slingshot lining, the first pellet shot from a slingshot hole (4) of described lock body (1), be respectively first magnetic bullet (5) and second magnetic bullet (6), both opposite faces are same polarity, second magnetic bullet (6) can be up and down in the second pellet shot from a slingshot hole (7) of the first pellet shot from a slingshot hole (4) of lock body (1) and lock core (2), the pellet shot from a slingshot hole (10) that spiral key (3) back is corresponding with the second pellet shot from a slingshot hole (7) of lock core (2) is embedded with the 3rd magnetic bullet (8), this magnetic bullet (8) is a same polarity with the opposite face of interior second magnetic bullet (6) in the lock body first pellet shot from a slingshot hole (4), first magnetic bullet (5) in the magnetic lock, the quantity of second magnetic bullet (6) and the 3rd magnetic bullet (8) is 2 groups.

The safety of the utility model magnetic lock is achieved in that

If with common key, the key back does not have magnetic patch, second magnetic bullet (6) can not inhale, and then magnetic lock can not be opened; If then can not open magnetic lock with magnetic metal rod key, because the quantity of first magnetic bullet (5), second magnetic bullet (6) and the 3rd magnetic bullet (8) in the magnetic lock of every lock is irregular in distribution more than 2 groups, and magnetic lock is spiral key hole (9); If use other instrument, then more can not push aside bilaterally one by one, more can not open magnetic lock.So the utility model magnetic lock safety, reliable.

Claims

1. magnetic lock, by lock body (1), lock core (2) and supporting spiral key (3) are formed, it is characterized in that: be provided with spiral key hole (9) in the described lock core (2), there is the pair of magnetic pellet shot from a slingshot in the first pellet shot from a slingshot hole of described lock body (1) for 4 li, be respectively first magnetic bullet (5) and second magnetic bullet (6), both opposite faces are same polarity, second magnetic bullet (6) can be up and down in the second pellet shot from a slingshot hole (7) of the first pellet shot from a slingshot hole (4) of lock body (1) and lock core (2), the pellet shot from a slingshot hole (10) that spiral key (3) back is corresponding with the second pellet shot from a slingshot hole (7) of lock core (1) is embedded with the 3rd magnetic bullet (8), and this magnetic bullet (8) is a same polarity with the opposite face of interior second magnetic bullet (6) in lock body (1) first pellet shot from a slingshot hole (4).
