Detailed Description

As shown in fig. 1, the invention is a magnetic engraving lock, which comprises a lock shell 1, a lock cylinder 2, a lock sleeve 3, a clamp spring 4, a row sheet 5, a spring 6, two long magnets 7, two middle magnets 8, two short magnets 9 and a key 10.

The lock cylinder 2 is movably sleeved in the lock cylinder 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 the clamp spring 31, and the lock sleeve 3 can rotate around the lock shell 1; the symmetrical inner walls of the lock cylinder hole 11 of the lock case 1 are respectively provided with a clamping groove 12 along the longitudinal direction, the row sheet 5 and the spring 6 are movably sleeved in the row sheet groove of the lock cylinder 2, the inner side of the lock cylinder 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 cylinder 2, the through grooves 211 and 212 are divided into left and right sides by taking the key hole 22 as a boundary, the two long magnets 7 are respectively movably sleeved on the left and right sides of the inner side through groove 211 and have the same magnetic poles at the inner ends of the two long magnets 7 to form repulsion, the outer ends of the two long magnets 7 can extend into the clamping groove 12 of the lock case 1, the two middle magnets 8 are respectively movably sleeved on the left and right sides of the outer side through groove 212, and the magnetic poles at the inner ends of the two middle magnets 8 are the same, and the two middle magnets 8 form repulsion; the two short magnets 9 are respectively and movably arranged in the clamping groove 12 of the lock shell 1, the magnetic poles of the inner ends of the short magnets 9 are opposite to the magnetic poles of the outer ends of the middle magnets 8, the short magnets 9 and the middle magnets 8 are attracted, and the short magnets 9 and the middle magnets 8 are positioned on the contact surface of the lock cylinder 2 and the lock shell 1, so that when the lock cylinder 2 rotates, the short magnets 8 and the middle magnets 9 can be separated.

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

The working principle of the invention is as follows:

as shown in fig. 2 and 3, the invention changes the traditional lock shell 1 into a whole structure, designs the head of the lock shell 1 into a lock sleeve 3 structure capable of rotating 360 degrees, and the lock sleeve 3 is assembled on the lock shell 1 by using a clamp spring 31; the lock sleeve 3 of the head of the lock after being installed can rotate by 360 degrees, when tools such as a locking pliers are used for clamping the lock head to unlock violently when in use, the lock can ensure that the lock body is fixed, only the head lock sleeve 3 rotates, the lock is prevented from unlocking violently, and the safety of the lock can be improved.

In addition, this key 10 adopts novel key structure, and the regional drilling of key 10 head appoints inserts iron plate 101, and when this key 10 inserted the tool to lock, the corresponding password row piece 5 of key 10 tooth formula corresponds, and the iron plate 101 that key 10 inserted can hold long magnet 7 moreover, makes long magnet 7 be in the shrink state, and magnet 8 corresponds the copper material of key non-iron insert in another row, and the middle magnet 8 that both sides correspond is homopolar assembly, makes the middle magnet 8 and the short magnet 9 of both sides repulse both sides, and middle magnet 8 meets with short magnet 9 and is in lock core 2 excircle, and lock core 2 can rotate, reaches the requirement of unblanking.

The imitated all-copper key and all-iron key can only open the password row sheets even if the milling teeth of the key are correct, but the key does not meet the design requirement in the area corresponding to the 2 rows of magnets, the repulsion and attraction of the magnets cannot be controlled according to the requirement, and the magnets are blocked in the lock shell clamping groove 12, so that the function of finally unlocking the lock cannot be achieved.

Various states of the present invention:

1. novel tool to lock is prevented violently unblanking: the lock body head adds a lock sleeve 3, adopts jump ring 31 to assemble on lock shell 1, and lock sleeve 3 and lock shell 1 can 360 degrees rotations, runs into when the use is closed by the violent rotation of instrument such as power tongs, and this tool to lock only lock sleeve 3 rotations, and lock shell 1 keeps motionless, 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 polarity repel each other, the magnets play a role of a lock bolt, and a clamping groove 12 in the lock shell 1 is clamped, so that the lock is in a locking state; the key 10 is not inserted, and the cipher row 5 assembled by the lock cylinder 2 is in a locking state.

3. As shown in fig. 3, the lock is unlocked: the key 10 is copper, is convenient for milling teeth, and is inlaid into the iron block 101 in a designated area of the head. After the key 10 is inserted, the milling teeth of the key 10 can open the corresponding cipher row 5; meanwhile, the iron insert 101 in the designated area of the head of the key 10 attracts the magnet in the corresponding position, so that the magnet is in an unlocking state; the middle magnet 8 in the right area is made of copper material corresponding to the key 10 without iron insert, the homopolar repulsion of the magnets cannot be attracted, the joint surface of the middle magnet 8 and the short magnet 9 at the tail part of the magnets is positioned at the outer circle of the lock cylinder 2, and the lock can be opened in a rotating way.

4. As shown in fig. 4, the lock is not unlocked (copy key 10A): the duplicate key 10A is all copper, and the duplicate key 10A has the same milling teeth shape as the original key 10. After the full copper duplicate key 10A is inserted, the milling teeth of the key 10A can open the corresponding cipher row 5; however, the key 10A is made of copper, magnets in all areas cannot be attracted, the magnets are in homopolar repulsive state, and the long magnets 7 on the left and right sides repel and then clamp the clamping groove 12 of the lock shell 1, so that the lock is in an unblanked state.

5. As shown in fig. 5, the lock is not unlocked (copy key 10B): the duplicate key 10B is full iron, and the shape of the milling teeth of the duplicate key 10B is the same as that of the original key 10B. After the full iron duplicating key 10B is inserted, the milling teeth of the key 10B can open the corresponding cipher row sheets; however, the key 10B is made of iron, all the magnets in the areas are attracted, the magnets of the short magnets 9 and the middle magnets 8 on the left and right sides are attracted by the key 10B, the middle part of the short magnet 9 is positioned on the outer circle of the lock cylinder 2, and the short magnet 9 enables the lock cylinder 2 to clamp the clamping groove 12 of the lock shell 1, so that the lock is in an unblanked state.

The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, i.e., the equivalent changes and modifications to the invention as described in the claims and specification should be considered as falling within the scope of the invention.
