Abstract

The utility model relates to a theftproof magnetic lock, which is composed of a lock body, a lock core, a lock sleeve, and a toothless key inserted in the lock core. The principle of the utility model is that the fastening and the opening purposes are achieved with homopolar repulsive force and heteropole attractive force. The utility model is characterized in that (1) the magnetic materials and the nonmagnetic materials are compounded together; (2) a spring is replaced with the magnetic force of a magnetic marble; (3) the size of key is improved with a magnetic conductivity key oriented aggregation magnetic path; (4) the volume is reduced and the shielding function is reinforced with a magnetic conductivity external tube; (5) the materials of the marble are a plurality of permanent magnetic materials; (6) the both ends of the magnetic marble are chamfered.

Description

Anti-theft magnetic lock

The utility model relates to a kind of Anti-theft magnetic lock

Existing various mechanical anti-theft lock, coded lock, electronic lock, magnetic card lock etc. have solved the antitheft problem of part to a certain extent, but have all that privacy degrees is low, mutual opening rate is high, manufacturing process is complicated, the life-span is short and many shortcomings such as cost height.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and reduces mutual opening rate, improves privacy degrees, Anti-theft magnetic lock safe and convenient to use.

The purpose of this utility model is achieved by the following technical solution:

The Anti-theft magnetic lock of forming by lock tube, lock body, lock core, pellet shot from a slingshot and key, it is characterized in that replacing original pellet shot from a slingshot with the chamfering magnetic bullet, form by three chamfering magnetic bullets, they are installed in the lock body respectively, between lock body and the lock core and on the key, in the time of in key inserts lock core, three chamfering magnetic bullets point-blank, between the pellet shot from a slingshot and pellet shot from a slingshot on the key of the pellet shot from a slingshot between lock body and the lock core in lock body, the polarity of per two chamfering magnetic bullet opposite positions is identical; Also can make between the pellet shot from a slingshot and the pellet shot from a slingshot between lock body and the lock core of pellet shot from a slingshot in lock body on the key; Also can be made up of two chamfering magnetic bullets, one of them chamfering magnetic bullet is installed on the key, and another is installed between lock body and the lock core, and the polarity of two chamfering magnetic bullet opposite positions is opposite, at this moment, and the lock tube permeability magnetic material; Also can be made up of four chamfering magnetic bullets, two pellets shot from a slingshot are housed in the lock body, they are respectively at the two ends of same straight line; Lock body and lock core are manufactured with non-magnet material, and lock tube and key can be manufactured with one of following material: (1). permeability magnetic material; (2). non-magnet material chamfering magnetic bullet can be manufactured with one of following material: (1). neodymium iron boron; (2). the cerium cobalt-copper alloy; (3). tin-cobalt alloy.

The utility model is made easily, and is safe and reliable

Below be description of drawings:

Fig. 1 is the utility model section of structure

Fig. 2 is the section of structure of the utility model embodiment 2.

Fig. 3 is the section of structure of the utility model embodiment 3.

Fig. 4 is the section of structure of the utility model embodiment 4.

Wherein, 1. key, 2. lock core, 3. lock body, 4. lock tube, 5-8. chamfering magnetic bullet.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment 1: structure as shown in Figure 1, form by three chamfering magnetic bullets, they are installed in the lock body 3 respectively, between lock body 3 and the lock core 2 and on the key 1, when key 1 inserts in the lock core 2, three chamfering magnetic bullets point-blank, between the pellet shot from a slingshot and the pellet shot from a slingshot on the key 1 of pellet shot from a slingshot between lock body 3 and the lock core 2 in lock body 3, the polarity of per two chamfering magnetic bullet opposite positions is identical, pellet shot from a slingshot 6 is released lock core 2 with pellet shot from a slingshot 5, realize purpose of opening: when key 1 is extracted, pellet shot from a slingshot 7 is pressed into pellet shot from a slingshot 5 between lock body 3 and the lock core 2, realizes locking admittedly purpose.

Embodiment 2: structure is made up of two chamfering magnetic bullets as shown in Figure 2, and one of them chamfering magnetic bullet is installed on the key 1, another is installed between lock body 3 and the lock core 2, the polarity of two chamfering magnetic bullet opposite positions is opposite, and at this moment, lock tube 4 is used permeability magnetic material.

Embodiment 3: structure is made up of three chamfering magnetic bullets as shown in Figure 3, and between 3 the pellet shot from a slingshot and the pellet shot from a slingshot between lock body 3 and the lock core 2, the polarity of per two pellet shot from a slingshot opposite positions is with embodiment 1 in lock body for the pellet shot from a slingshot on the key 1.

Embodiment 4: structure is made up of four chamfering magnetic bullets as shown in Figure 4, and two pellets shot from a slingshot are housed in the lock body, and they are respectively at the two ends of same straight line.
