Abstract

The utility model relates to a lockset, particularly a magnetic cylinder lock, which is composed of a lock body, a lock core, a cylinder, a key, etc. The utility model utilizes a magnetic principle, the cylinder and a cylinder spring in the cylinder lock is changed into a magnetic cylinder, and a magnet is arranged at the position of the key corresponding to a cylinder hole. A fixed cylinder and a movable cylinder which are opposite and have the same polarity can be arranged in the same cylinder hole, or a fixed magnetic cylinder and a movable magnetic cylinder which are opposite and have different polarities are arranged in symmetrical cylinder holes at both sides of a lock core hole. The magnet on the key has the same polarity with the adjacent polarity of the movable magnetic cylinder. The utility model has the advantages of easy fabrication, reasonable process, flexible unlocking, and high safety, and is a safety lock with high security.

Description

Magnetic lock

The utility model relates to lockset, a kind of magnetic lock.

In the existing lock, use more extensively, what occupation rate of market was higher mainly is mechanical cylinder lock.Because structural restriction.This lock processing is complicated, its mutual opening rate height, and safety and reliability are relatively poor.In order to overcome these shortcomings, people are doing a lot of work aspect the transformation of cylinder lock.It is ZL92239266.8 that Patent Office of the People's Republic of China discloses a kind of patent No., and name is called the utility model patent of permanent magnetism safety lock.The principle that this Lock Lee is repelled each other with the permanent-magnet material same sex changes part or all of pellet shot from a slingshot into magnetic marble, has kept marble spring.The lock magnetic marble reseting performance of this structure is poor, and the lock core polarization is bad, occurs the phenomenon of not opening in the use, has influence on applying of this lock.

The purpose of this utility model is to utilize magnetic principles that cylinder lock is improved, and replaces pellet shot from a slingshot and marble spring with magnetic bullet, provides a kind of processing technology simple, and cost is low, open easy to use, safe and reliable, the safety lock of strong security.

This magnetic lock is that peace is repelled each other according to the magnetic material same sex, and the physical characteristic that there is a natural attraction between the sexes utilizes its repulsion and suction to use the pellet shot from a slingshot in the mechanical cylinder lock and marble spring instead magnetic bullet and the novel lockset created.

Fig. 1 is for adorning the structural representation of two magnetic bullets in the same pellet shot from a slingshot of the utility model hole;

Fig. 2 is for installing the structural representation of a magnetic marble respectively in the symmetry pellet shot from a slingshot hole, the utility model lock core hole both sides.

Be described in detail by reference to the accompanying drawings the utility model structure.

As shown in the figure, magnetic lock is by lock body [1], lock core [2], key [3], lock core positioning ball (or alignment pin) [4], lock core retainer spring [5] consist of. The magnetic bullet is installed in the marble hole on lock body [1] Son, magnet [3-1] is equipped with in the position of inserting the corresponding marble hole of key [3] of lock core [2]. At same pellet Two magnetic marble [1-1] and [1-2] that same polarity is relative are installed, near the magnetic marble [1 of lock core in the hole-2] be moving magnetic marble, [1-1] is for deciding magnetic marble. Perhaps in the marble hole of lock core hole both sides symmetry, Two magnetic marbles that opposed polarity is relative are installed respectively, with the pellet [1 that magnet [3-1] is corresponding on the key-2] be moving magnetic marble, [1-1] is for deciding magnetic marble. Magnet [3-1] on the key [3] and the son [1 of moving-2] polarity of two adjacent utmost points is identical. Magnetic marble is to make with the NdFeB rear-earth material. Lock body [1], lock core [2], key [3] are non-magnetic with aluminium alloy, copper alloy, allumen or engineering plastics etc. The property material is made.

The unlatching and the locking of this lock are realized by magnetic force that fully the magnet in the key does not expose, and are difficult to the imitated security personnel's performance that improves lock.Utilize the polarity of magnetic marble and the variation of distributing position, make lockset be difficult to open mutually, improve the reliability of lock.It is rational in infrastructure, and manufacturing process is simple, opens flexibly long service life.This structure is applicable to various locksets.

Embodiment 1:

As shown in Figure 1, lock body [1] Built-in lock core [2].Lock core [2] is by lock core positioning ball (or alignment pin) location, and lock core rotates under the situation of location.Adorn in lock body [1] is gone up the pellet shot from a slingshot hole that two identical polars are corresponding decides magnetic marble [1-1] and moving magnetic marble [1-2], then the pellet shot from a slingshot hole is sealed.6 in pellet shot from a slingshot hole (or more) is arranged on the lock body [1], lock core [2] is gone up 6 holes (or more) that moving magnetic marble [1-2] is held in corresponding processing, be inserted in (being the magnetic marble in the corresponding pellet shot from a slingshot hole) position, pellet shot from a slingshot hole on the corresponding on the key core in the lock core, 6 (or more) two magnets that utmost point polarity identical adjacent of corresponding concealed installation with moving magnetic marble [1-1].When not inserting key in the lock core, decide magnetic marble [1-1] and moving magnetic marble [1-2] is in the state that repels each other, the magnetic force that repels each other will move magnetic marble [1-2] and push pellet shot from a slingshot hole on the lock core [3], moving magnetic marble [1-2] is inserted in the pellet shot from a slingshot hole and the lock core of lock body [1] and cheats between the two, lock core can not be rotated, and lock promptly is in locking states.When key [3] reeve lock core [2], the magnet [3-1] on the key [3] is aimed at moving magnetic marble [1-2], and its repulsive force has overcome the mutual expelling force of fixed, moving magnetic bullet, will move in the pellet shot from a slingshot hole of magnetic marble [1-2] propelling lock body [1], and lock is promptly opened.Lock body and lock core and key are manufactured with allumen.

Embodiment 2:

As shown in Figure 2, lock core [2], lock core [2] are installed in the lock body [1], are loaded onto aperture sealing behind the retainer spring by positioning ball (or alignment pin) [4] location.The both sides processing 6 that lock body [1] is gone up and lock core is symmetrical is to (or more) pellets shot from a slingshot hole.On lock core [2], 6 (or more) pellets shot from a slingshot holes of the pellet shot from a slingshot hole site processing of the moving magnetic marble of corresponding dress.In each pellet shot from a slingshot hole, install respectively symmetry opposed polarity relative moving, decide magnetic marble, then the pellet shot from a slingshot hole is sealed.When not inserting key, the attraction of magnetic marble makes in pellet shot from a slingshot hole on the magnetic marble reeve lock body and the pellet shot from a slingshot on the lock core cheat in the every pair of pellet shot from a slingshot hole, and lock core can not rotate, and lock is a locking.When injecting key, owing to be equipped with and move the identical magnet of magnetic marble consecutive roots polarity with corresponding position, pellet shot from a slingshot hole on the key, at this moment the repulsive force of magnet [3-1] has overcome moving, as to decide magnetic bullet suction, will move magnetic marble and advance the pellet shot from a slingshot hole, lock core can rotate, and lock is promptly opened.This lock body and lock core and key can be manufactured with copper alloy.Magnetic marble and magnet are manufactured with the NdFeB rear-earth material.

Utilize the different distributions position in pellet shot from a slingshot hole and the method that the magnetic marble change in polarity combines, can make the reliability that the magnetic lock of not reopening has in a large number improved lock.
