Detailed Description

As shown in fig. 1, the utility model relates to a magnetism sculpture lock, including lock shell 1, lock core 2, lock sleeve 3, jump ring 4, row's piece 5, spring 6, two long magnets 7, two well magnets 8, two short magnets 9, key 10.

The lock core 2 is movably sleeved in the lock core hole 11 of the lock shell 1, the lock sleeve 3 is movably sleeved at the outer end of the lock shell 1, the lock sleeve 3 is clamped on the lock shell 1 through a clamp spring 31, and the lock sleeve 3 can rotate around the lock shell 1; the inner wall of the lock core hole 11 of the lock shell 1 is symmetrical and is respectively provided with a clamping groove 12 along the longitudinal direction, the row sheets 5 and the spring 6 are movably sleeved in the row sheet groove of the lock core 2, the inner side of the lock core 2 is provided with two through

grooves

211 and 212 which are arranged along the radial direction, the through

grooves

211 and 212 penetrate through a key hole 22 in the middle of the lock core 2, the through

grooves

211 and 212 are divided into a left side and a right side by taking the key hole 22 as a boundary, the two long magnets 7 are respectively movably sleeved on the left side and the right side of the through groove 211 at the inner side, the magnetic poles at the inner ends of the two long magnets 7 are the same to form repulsion, the outer ends of the two long magnets 7 can extend into the clamping groove 12 of the lock shell 1, the two middle magnets 8 are respectively movably sleeved on the left side and the right side of the through groove 212 at the outer; two short magnets 9 are movably arranged in a clamping groove 12 of the lock shell 1 respectively, the inner ends of the short magnets 9 are opposite to the outer end of the middle magnet 8 in magnetic pole, the short magnets 9 and the middle magnet 8 form attraction, and the short magnets 9 and the middle magnet 8 are positioned on the contact surface of the lock core 2 and the lock shell 1, so that when the lock core 2 rotates, the short magnets 8 and the middle magnet 9 can be separated.

The body of the key 10 is made of copper material, an iron block 101 is embedded in the head of the key 10, and when the key 10 is inserted into the key hole 22 in the middle of the lock core 2, the iron block 101 is opposite to the long magnet 7.

The utility model discloses a theory of operation:

as shown in fig. 2 and 3, the lock shell 1 of the traditional lock is changed into an integral structure, the head of the lock shell 1 is designed into a lock sleeve 3 structure capable of rotating 360 degrees, and the lock sleeve 3 is assembled on the lock shell 1 by a clamp spring 31; the lock sleeve 3 of the tool to lock head after the installation can 360 degrees rotations, and in the use, when meetting maliciously and carrying the tapered end violently to unblank with instruments such as pincers, this lock can guarantee that the lock body is fixed, and only head lock sleeve 3 rotates, prevents that the violence from unblanking, can promote the tool to lock security.

In addition, the key 10 adopts a novel key structure, an iron block 101 is embedded in a specified area of the head of the key 10 through drilling, when the key 10 is inserted into a lockset, the tooth shape of the key 10 corresponds to the corresponding password row piece 5, the iron block 101 embedded in the key 10 can attract the long magnet 7, so that the long magnet 7 is in a contraction state, the magnet 8 in the other row corresponds to a copper material which is not embedded with iron in the key, the middle magnets 8 corresponding to two sides are assembled in the same pole, so that the middle magnets 8 and the short magnets 9 on two sides are repelled to two sides, the middle magnets 8 and the short magnets 9 are connected to be positioned at the excircle of the lock cylinder 2, and the lock cylinder 2 can rotate to meet the unlocking requirement.

Even if the key is milled correctly, the imitated all-copper key and the imitated all-iron key only can open the password row piece, but the key does not meet the design requirement in the area corresponding to the 2 rows of magnets, the repulsion and the attraction of the magnets cannot be controlled according to the requirement, the magnets are clamped in the clamping groove 12 of the lock shell, and the function of finally unlocking the lock cannot be achieved.

The utility model discloses a various states:

1. novel violence of tool to lock is unblanked: the lock body head increases a lock sleeve 3, adopts jump ring 31 assembly on lock shell 1, and lock sleeve 3 can 360 degrees rotations with lock shell 1, and when running into the use and being violently unlocked by instruments such as maliciously with the locking pliers violently the rotation, this tool to lock only lock sleeve 3 is rotatory, and lock shell 1 keeps fixed, guarantees the function of locking.

2. As shown in fig. 2, the lock is locked: two rows of holes in the lock core 2 are respectively provided with a long magnet 7 and a middle magnet 8, magnets assembled in the same poles repel each other, and the magnets play a role of a lock bolt to clamp a clamping groove 12 in the lock shell 1, so that the lock is in a locked state; the key 10 is not inserted, and the code row piece 5 assembled with the lock cylinder 2 is in a locked state.

3. As shown in fig. 3, the lock is unlocked: the key 10 is made of copper, so that the milling processing is convenient, and an iron block 101 is embedded in a designated area of the head. After the key 10 is inserted, the corresponding code row piece 5 can be opened by milling teeth of the key 10; meanwhile, the iron insert 101 in the designated area of the head of the key 10 attracts the magnet at the corresponding position, so that the magnet is in an unlocking state; and the middle magnet 8 in the right area is copper material corresponding to the key 10 without iron insert, and can not attract the magnet homopolar outward repulsion, and the middle magnet 8 and the short magnet 9 of the magnet tail part are connected in the excircle of the lock core 2, and can be rotated to unlock.

4. As shown in fig. 4, the lock is unlocked (imitation key 10A): the duplicate key 10A is all copper and the duplicate key 10A is milled with teeth shaped to the original key 10. After the all-copper duplicate key 10A is inserted, the corresponding code row piece 5 can be opened by milling teeth of the key 10A; however, the key 10A is made of copper, magnets in all areas cannot attract each other, the magnets are in the homopolar repelling state, and the magnets 7 on the left side and the right side are repelled to clamp the clamping grooves 12 of the lock shell 1, so that the lock is in the non-unlocking state.

5. As shown in fig. 5, the lock is unlocked (imitation key 10B): the duplicate key 10B is all iron and the duplicate key 10B is milled with teeth shaped to the original key 10B. After the all-iron duplicate key 10B is inserted, the milling teeth of the key 10B can open the corresponding code row sheets; however, the key 10B is made of iron material, magnets in all areas are attracted, the magnets of the short magnets 9 and the middle magnet 8 on the left side and the right side are attracted by the key 10B, the middle part of each short magnet 9 is positioned on the outer circle of the lock cylinder 2, and the short magnets 9 enable the lock cylinder 2 to clamp the clamping grooves 12 of the lock shell 1, so that the lock is in an unlocked state.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
