Detailed Description

For better understanding of the purpose, structure and function of the present invention, the lock of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the lock of the present invention includes a first lock 100 and a second lock 200, which can be locked with each other, wherein the first lock 100 is fixedly disposed on a first object to be locked, and the second lock 200 is fixedly disposed on a second object to be locked; the second lock body 200 may be attracted by magnetic force, and the exterior of the first lock body 100 may generate or remove the magnetic force; when the first lock 100 and the second lock 200 are close to each other, the first lock 100 may attract or separate the first lock 100 and the second lock 200 to each other by switching the generation and elimination states of the magnetic force, thereby realizing the mutual locking or unlocking state of the first object and the second object.

Further, the first lock 100 includes a magnetic closing component, a receiving cavity is formed in the magnetic closing component, and the permanent magnet is disposed in the receiving cavity. The closed magnetic assembly is made of permalloy, nickel-iron alloy and other magnetic materials, and when the permanent magnet is completely enclosed in the magnetic materials, namely when a closed magnetic space is formed in the closed magnetic assembly, the magnetic field of the permanent magnet can be shielded in the closed magnetic space, so that the outside of the closed magnetic assembly does not generate magnetic force.

The magnetism closing assembly is provided with a magnetic flux opening, and the magnetic flux opening can open a magnetism closing space in the magnetism closing assembly to relieve the shielding effect of the magnetism closing space on the magnetic field of the permanent magnet, so that the permanent magnet and the magnetism closing assembly generate magnetic force capable of adsorbing the second lock body 200. This is because the magnetic closing component is made of a magnetically permeable material, and when the permanent magnet is not completely closed by the magnetically permeable material and is in contact with or close to a part of the magnetically permeable material, the magnetically permeable material generates magnetic force under the magnetization of the permanent magnet, that is, the magnetic closing component generates magnetic force under the magnetization of the permanent magnet, so that the first lock body 100 and the second lock body 200 are fixed in an adsorbing manner.

The position close to the magnetic flux opening is movably provided with a magnetic flux blocking part which is also made of permalloy, ferronickel alloy and other magnetic conductive materials. The magnetic flux blocking part can open or close the magnetic flux opening, when the magnetic flux blocking part is positioned at the open position, a magnetic flux path can be formed outside the magnetic closing assembly, and the N pole and the S pole of the permanent magnet can form closed magnetic lines of force through the magnetic flux path, so that magnetic force capable of adsorbing the second lock body 200 is generated outside the magnetic closing assembly; when the magnetic flux blocking part is located at the closed position, the magnetic closing assembly and the magnetic flux blocking part jointly enclose a magnetic closing space so as to shield the magnetic field of the permanent magnet in the magnetic closing space, and further the outside of the magnetic closing space does not generate magnetic force, namely the outside of the magnetic closing assembly loses the magnetic force.

Further, the magnetic closing assembly comprises a magnetic closing block, a groove structure is arranged on the inner wall of the magnetic closing block, and the groove structure forms an accommodating cavity for accommodating the permanent magnet; the magnetic flux opening is arranged on the side wall of the closed magnetic block to open the closed magnetic space in the closed magnetic block so as to form a magnetic flux path outside the closed magnetic block; the permanent magnet may magnetize the closed magnetic block through a magnetic flux path to generate a magnetic force outside the closed magnetic block.

Preferably, the magnetic flux opening is further provided with a magnetic opening sheet, and the magnetic opening sheet can be made of non-magnetic materials such as brass, aluminum and the like. Because the open magnetic sheet is not magnetic conductive, the open magnetic sheet closes the magnetic flux opening in the physical structure, so that the closed magnetic blocks are connected into a whole, but the magnetic field of the permanent magnet cannot be shielded, and the magnetic flux path formed outside the closed magnetic blocks cannot be blocked.

Further, magnetic flux separation portion includes the mount, and the mount activity sets up in groove structure, and the permanent magnet setting is on the mount. The fixing frame is also provided with a magnetic closing part and a magnetic opening part, and the magnetic closing part is adjacent to the magnetic opening part. The magnetic closing part and the magnetic opening part can switch positions along with the movement of the fixed frame in the groove structure, so that the magnetic closing part or the magnetic opening part is opposite to the magnetic flux opening position. When the closed magnetic part is opposite to the position of the magnetic flux opening, the magnetic force of the permanent magnet is shielded; when the opening magnetic part is opposite to the magnetic flux opening position, the magnetic force can be generated outside the first lock body 100.

Further, the fixed frame is preferably in rotary connection with the magnetic closing block, and the fixed frame switches the positions of the permanent magnet and the magnetic closing part through rotary motion. Certainly, the fixed frame can also adopt sliding fit structures such as a sliding block and a sliding rail, and the positions of the permanent magnet and the magnetic closing part are changed in the accommodating cavity through sliding motion; or a hinge structure such as a hinge is adopted, and the position switching of the permanent magnet and the magnetic closing part is realized through the overturning motion.

Besides the above-mentioned manner of adopting the fixing frame and other structures, other forms can also be adopted to realize the switching of the magnetic force state of the first lock body 100. For example, the permanent magnet is fixedly arranged in the accommodating groove, so that the N pole and the S pole of the permanent magnet are attached to or arranged close to the closed magnetic block, meanwhile, the closed magnetic part in the form of a baffle plate is arranged at the magnetic flux opening, the baffle plate can move to the magnetic flux opening in the forms of rotation, sliding, overturning and the like, the magnetic flux opening is closed, the baffle plate and the closed magnetic component jointly surround the permanent magnet, and the shielding of the magnetic field of the permanent magnet is further realized.
