Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention is described in detail below with reference to the attached drawings.

As shown in fig. 1 to 5, the combined magnet provided by the present invention includes a housing 1, a first magnet 2, two second magnets 3 and two third magnets 4, wherein the first magnet 2 is disposed between the two second magnets 3, and the two second magnets 3 are disposed between the two third magnets 4; the magnetic pole direction of the first magnet 2 is opposite to the magnetic pole direction of the two third magnets 4, the magnetic pole direction of the two second magnets 3 is perpendicular to the magnetic pole direction of the first magnet 2, the magnetic pole direction of the two second magnets 3 is opposite to each other, and the magnetic pole direction of the two third magnets 4 is perpendicular to each other.

The performance of a magnet generally refers to the strength of its magnetic force, i.e., the performance of the magnet is considered to be better when the force applied to an external object by the magnet is larger. In practical use, as shown in fig. 1, the first magnet 2 has an N-pole top, the third magnet 4 has an S-pole top, the left third magnet 4 has an S-pole right-side polarity, and the right magnet has an S-pole right-side polarity. Through the structural combination, compared with the magnet with the same volume and the same material, the magnetic field intensity of the utility model has larger magnetic field intensity, thereby saving the cost and being capable of being installed in the flat equipment with smaller thickness for use.

In the present embodiment, two ends of the first magnet 2 are respectively connected to two second magnets 3, and the two second magnets 3 are respectively connected to two third magnets 4. That is, according to the present invention, the third magnet 4, the second magnet 3, the first magnet 2, the second magnet 3, and the third magnet 4 are connected in sequence, so that different magnets can be brought into close contact with each other to form a whole, and magnetic field lines do not interfere with each other due to the existence of a gap, thereby stabilizing the magnetic properties of the present invention.

Specifically, the connection between the magnets may be a tight contact, or may be performed by welding, bonding, or the like, which is not described herein again.

In the present embodiment, the housing 1 is a hollow structure with an open top, and the first magnet 2, the two second magnets 3, and the two third magnets 4 all protrude from the top of the housing 1 to protrude out of the housing 1. Namely, the housing 1 is used for mounting the first magnet 2, the second magnet 3 and the third magnet 4, so that the magnets are stably mounted and are kept in reliable contact with each other, thereby ensuring better stability of the utility model; furthermore, the magnet protrudes out of the housing 1 for ensuring that the magnetic properties of the magnet are not disturbed.

In this embodiment, the housing 1 is formed by bending a metal sheet, so that the integrity of the housing 1 is higher, and the housing 1 made of metal is also magnetically attracted by the magnet to be in close contact with the magnet, so that the magnet does not move in the housing 1.

In this embodiment, casing 1 is provided with five at least jacks 11, first magnet 2, two second magnets 3 and two third magnets 4 are provided with inserted sheet 5 respectively, and five inserted sheets 5 are pegged graft with five jacks 11 one-to-one, and inserted sheet 5 runs through jack 11 back bending and forms spacing portion 6. The insert 5 is bent after being inserted into the jack 11, so that the magnet is reliably assembled in the shell 1, the stability of the utility model is better, and the magnet cannot be separated from the shell 1 under the action of external force.

Specifically, the bottom of casing 1 is provided with spacer 7, spacer 7 is provided with five at least isolation grooves 71, and isolation groove 71 is used for holding spacing portion 6, spacer 7 with casing 1 welding. The spacer 7 is used for wrapping the limiting part 6, so that the limiting part 6 is protected, and the limiting part 6 can not be exposed outside, so that the appearance of the utility model is not influenced too much.

In the embodiment, the cross sections of the first magnet 2, the two second magnets 3 and the two third magnets 4 are all triangular, so that the magnetic field generating device can be applied to specific occasions to ensure that the effect of the magnetic field is smoothly realized.

In the present embodiment, the length of the second magnet 3 is smaller than the length of the first magnet 2, and the length of the second magnet 3 is smaller than the length of the third magnet 4. The second magnet 3 is mainly used for assistance, so that the length thereof is not too long, which would otherwise affect the performance of the present invention.
