Abstract

The utility model discloses a cipher lock and the key of the cipher lock, and the cipher lock is composed of a lock body, a cylinder, a spring and a lock core. The utility model is characterized in that the lock cylinder is composed of an original common lock cylinder and a magnetic cylinder, and the upper end of the lock spring is provided with a screw bolt whose elasticity can be adjusted. The key is welded with a toothed magnetic block which is matched with the magnetic cylinder. The lock and the key have the recognizing ability, the key can not be imitated, and the defects that the traditional key has monotonic teeth variation and has poor confidentiality are overcome.

Description

Cipher lock

The utility model relates to a kind of coded lock, comprises lock and key.

Popular in the market common lock, the ubiquity security performance is poor, and key is easily copied, and mechanical code lock, on the insurance frame, one is mechanical code lock, one is common lock, because the long-term mechanical wear of bringing of using easily can be opened the burglar with the sense of hearing or sensation.Various electronic password lock scrambling coding figure places are all quite big, and electronic devices and components have been adopted, so reliability is lower, moreover adopt electronic lock that electric operator must be arranged, so both increased cost, brought unreliability (as having a power failure or the battery electric energy is used up) again, there are plenty of such people for Here it is electronic password lock development and exploitation, but be difficult to the principal element promoted on the market.Magnetic lock in the past also the someone research and develop, but since the problem in design and the material selection fail all the time to be accepted by market.For fear of above the deficiencies in the prior art part.

The purpose of this utility model is to design a kind of improvement that adds on the basis of former common lock and key, makes lock have recognition capability to key, and key can not be copied, a kind of coded lock and key thereof that confidentiality is high.

The utility model is to realize with following technical measures: it is made of lock body 1, spring 4, lock core 6 and pellet shot from a slingshot.Wherein pellet shot from a slingshot is that magnetic block 2 by common spring 3 and its lower end is constituted, and the bolt 5 that can regulate elastic force is housed on the top of spring 4.And key is to weld a profile of tooth magnetic block 8 on former key body 7 and with the magnetic bullet place of matching in the lock.Pellet shot from a slingshot in the coded lock can be being made of common spring and magnetic block of part, and lock core marble can be that single face also can be two-sided simultaneously.Described key can be that single cog also can be a double cog.

The utility model has the advantages that key can not forge, the password figure place can reach more than one hundred million portions, and cryptographic capabilities improves greatly, and manufacturing process and traditional being more or less the same are easy to make.

Description of drawings of the present utility model:

Fig. 1 is the structural representation of the utility model lock.

Fig. 2 is the structural representation of the utility model key.

In conjunction with Fig. 1-2 structure of the present utility model and performance thereof are further described;

Shown in Figure 1, be magnetic bullet 2 with magnetic block, common spring 3, spring 4 is pressed in the pellet shot from a slingshot hole sequentially, screws in screw 5 at last, and this has just constituted one of core of the present utility model magnetic bullet part.Shown in Figure 2 in addition tooth magnetic block 8 is welded on rational position on the key body, has just constituted new key.Key is inserted in the lock core, except magnetic bullet, all the other pellets shot from a slingshot all are subjected to the thrust of former key tooth and are shifted, at this moment, magnetic bullet 2 is mobile because of the repulsion that is subjected to magnetic lock key bit 8 also produces, and the size of this repulsive force makes stressed the changing of spring by adjustment screw 5, and the position of suitable adjusting spiral shell left alone without help 5 always can make that magnetic bullet partly is in lockset position of coupler, so far, the adjusting of lock is all finished.Magnetic block 2 in the coded lock also can be described as profile of tooth magnetic block 8 on magnetic bullet 2 and the key and is the superpower magnetic material of NdFeB and manufactures, so the magnetic field intensity of the magnetic patch 8 on magnetic bullet 2 and the key body can be divided into a plurality of magnitudes of number; Polarity of the magnetic field is also variable, and both sides' polarity can be the same sex, also can be different in nature; The key tooth is corresponding with lock core, can partly be common tooth, and part is the NdFeB magnetic material; Lock core marble can be made two-sided pellet shot from a slingshot, also can make the single face pellet shot from a slingshot, and key also can be made double cog simultaneously, also can make single cog; The stressed adjustable size of pressure marble spring of lock so make the coding of key can reach more than one hundred million sign indicating numbers by above-mentioned various performances, has increased the security performance of this lock and key widely.

Claims

1, a kind of coded lock, constituted by lock body (1), spring (4), lock core (6) and pellet shot from a slingshot, it is characterized in that described pellet shot from a slingshot is to be added with NdFeB magnetic block (2) in the lower end of common spring (3) to constitute, and is equipped with the screw (5) that can regulate elastic force on the top of described spring (4).

2, a kind of key that is used to open this coded lock is characterized in that on common key body (7), and welds a profile of tooth NaFeB magnetic block (8) with interior NaFeB magnetic block (2) place of matching of lock.

3,, it is characterized in that described lock core marble can be part pellet shot from a slingshot and magnetic block (2) combination, and remainder can keep former pellet shot from a slingshot shape by the described a kind of coded lock of claim 1.

4, by the described a kind of coded lock of claim 1, it is characterized in that described lock core marble can make two-sided pellet shot from a slingshot, also can be the single face pellet shot from a slingshot.

5,, it is characterized in that the described key tooth that has magnetic patch can be for two-sided by the described a kind of key that is used for coded lock of claim 2.
