Abstract

The utility model relates to a magnetic lock core and the special key of the magnetic lock core, and the traditional structure of the existing lock core and the key is changed. The inner part of the cylinder hole of a lock core body is provided with magnetic particles, the inner part of a key hole is provided with a protective lining, and the upper part of a key body is provided with the magnetic particles which are corresponding to the magnetic particles on the lock core body. The magnetic particles on the lock core are attracted or are repulsed to the prearranged position by using the principle that the like polarities of magnetic bodies are repellent and the heteropolarities are attractive, and the lock can be opened. The utility model has the advantages that the utility model is suitable for the large-scale industrial production, the safety and the confidentiality of the lock are good, and the operation is convenient and reliable.

Description

Magnetic lock core and its key

The utility model relates to a kind of magnetic force lock core and private key thereof that is applicable to various locks.

Existing padlock or built-in lock all adopt lock cylinder usually, be equipped with the key of dissimilar tooth form again, promptly on lock core and lock body, process several corresponding mutually holes, the cylinder-shaped marble and the spring of several different lengths of packing into therein, utilize associated key to come rotational lock core, lock is opened.Because the size of lock and confidentiality require different, lock core and the groove that processes on the key and quantity are all inequality, and the profile of tooth of key is also inequality, and this just causes certain difficulty to batch process.When producing this lock, at first will process the key of dissimilar tooth form, and then according to the pellet shot from a slingshot of the profile of tooth repair lock core of key, therefore, existing lock cylinder and key are not suitable for industrial production in enormous quantities; Use also very inconveniently, a key can only be driven a lock, and everyone needs to be with a string several at least, tens copper, iron, the various key of aluminium at most, heavy one-tenth be burdensome, also to look for key when unblanking to lock, both bothered, time-consuming again.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the traditional structure that has lock core and key now is improved, and provides a kind of easy to use, the magnetic force lock core and the private key thereof that are suitable for producing in batches.

The utility model is achieved in that

The utility model magnetic force lock core has a lock core body, in the pellet shot from a slingshot hole of lock core body the magnetic grain is installed, and pellet shot from a slingshot that matches with it and spring, in the keyhole of lock core body lining is installed, and enters in the keyhole to avoid the magnetic grain.

In order to open above-mentioned said magnetic force lock core, the utility model also has a private key that matches and use with it, it has a key body, be equipped with on the key body with lock core body on the corresponding magnetic grain of magnetic grain, according to the principle that the magnetic same polarity is repelled each other, heteropolarity is inhaled mutually, on key body, suitably discharge the polarity of magnetic grain, lock core body is repelled each other with magnetic grain on the key body or inhale mutually, can or repel and give fixed position the attraction of the magnetic grain on the lock core body, rotation or translation lock core just can be opened lock.

The utility model compared with prior art has following advantage:

1, according to the magnetic same polarity is repelled each other, heteropolarity is inhaled mutually principle, utilize pushing away mutually, inhaling and unblank of magnetic grain, changed the traditional structure of lock core and key, its production technology is more simple, only needs to change the rigging position of magnetic grain in lock core and the key and the direction of conversion magnetic grain magnetic pole when assembling, just can obtain several ten thousand not same lock, and do not need to carry out again repair, therefore, be suitable for large-scale industrial production, reduce the cost of lock.

2, lock core and key can be processed into some classifications, the lock core of every class and the shape of key also can be made varied, magnetic grain wherein can be installed single, double or many rows, can be parallel to each other, also can be staggered, the key of having guaranteed every lock is not same, has improved the level security of lock.

3, the user can remove the lock of encoding and oneself newly purchasing according to existing magnetic force key, no matter make oneself has how many handles, how many kinds of to lock, so long as the like product of own former series, through own simple coding, be the position and the polar orientation of corresponding transposing magnetic grain, just can drive several locks with a key, for less lock, key also can partly inject, utilize its first half that lock is opened, for bigger lock or the demanding lock of level security, key all can be injected and unblank, easy to use, reliable.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the structural representation of the utility model magnetic force lock core;

Fig. 4 is the structural representation of the utility model private key;

Fig. 5 is the vertical view of Fig. 4.

As shown in the figure, the utility model magnetic force lock core has a lock core body 1, and lock core body 1 adopts nonferromugnetic materials such as aluminium or copper to make, be processed with the pellet shot from a slingshot hole on lock core body 1, the pellet shot from a slingshot hole can be single, also can be double or many rows, the position, hole can be parallel to each other, and also can be staggered; In the pellet shot from a slingshot hole of lock core body 1, magnetic grain 4 is installed, and pellet shot from a slingshot 3 that matches with it and spring 2, magnetic grain 4 can according to the position in pellet shot from a slingshot hole install single, double, arrange more, be parallel to each other or be staggered, the password separately of forming a lock set, can also vacate several pellet shot from a slingshot holes, omit several magnetic grains 4, pellet shot from a slingshot 3 and spring 2, not same to guarantee each lock, improve the security performance of locking; Lining 5 is installed in the keyhole of lock core body 1, and lining 5 adopts nylon or plastic productions, and with in the firm keyhole that is attached to lock core body 1 of glue, enters in the keyhole to avoid magnetic grain 4.

Above-mentioned said magnetic force lock core has a private key that matches and use, and described private key has a key body 7, and nonferromugnetic materials such as key body 7 usefulness aluminium or copper are made, be equipped with on the key body 7 with lock core body 1 on magnetic grain 4 corresponding magnetic grains 6; Diaphragm 8 also is equipped with on surface at key body 7, comes off from key body 7 to prevent magnetic grain 6, and described diaphragm 8 usefulness plastics or nylon are made, with the surface of sticker at key body 7.

The polarity of above-mentioned said magnetic grain 4 is can homopolarity staggered relatively, and is also can heteropole staggered relatively, when key does not insert, repels each other each other or inhale mutually, and lock core is in blocking; Adjust the polarity of the magnetic grain 6 on the key body 7, its polarity with magnetic grain 4 is complementary, after the key insertion, interact between magnetic grain 6 and the magnetic grain 4, magnetic grain 4 and pellet shot from a slingshot 3 arrive and give allocation, and lock core is in opening, rotation or translation lock core can be opened lock.
