Description

Technical Field

[0001] The utility model relates to the technical field of flexible magnets, in particular to a flexible magnet. Background Art

[0002] Flexible magnets usually refer to flexible magnetic materials, which are materials that can be bent, stretched or squeezed without losing their magnetism. This material is usually made of flexible magnetic powder mixed with a binder. Flexible magnets are useful in many applications, such as making magnetic stickers, magnetic labels, magnetic closures, etc. Due to their flexibility and plasticity, flexible magnets can be made into various shapes and sizes, making them suitable for different application scenarios.

[0003] The existing flexible magnet structure is extremely simple, mostly in the form of a sheet. The strip and disc structures are mostly cut from the sheet structure. The flexible magnet structure is soft, but has low fatigue strength. It is easy to make the bending angle too large when bending. After multiple large-angle bending, cracks will appear at the bending point, and the surface wear resistance of the flexible magnet is low. When the flexible magnet is in use, it is generally directly adsorbed with other magnetic metals or magnetic materials through the surface, which will inevitably cause the surface of the flexible magnet to be rubbed, resulting in damage to the surface of the flexible magnet. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing flexible magnets have low fatigue strength, are prone to cracks, and have low wear resistance, which easily causes damage to their surfaces.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is a flexible magnet, including a flexible magnetic plate body, a hollow area is opened inside the flexible magnetic plate body, a plurality of elastic pillars are obliquely fixed inside the hollow area, a plurality of magnetic protrusions are fixed on the upper and lower sides of the flexible magnetic plate body, a shallow groove is opened on the upper side of the magnetic protrusion block, a highly wear-resistant rubber sheet is glued and fixed in the shallow groove, and a connecting structure is fixed around the flexible magnetic plate body.

[0006] As a further solution of the utility model: the connection structure includes groove structures fixed on two adjacent sides of the flexible magnetic plate body, and the other two adjacent side surfaces of the flexible magnetic plate body are fixed with plug-in structures.

[0007] As a further solution of the utility model: a plug-in groove is opened on one side of the groove structure, and limit grooves are opened on the upper and lower sides of the plug-in groove; a plug-in plate is fixed on one side of the plug-in structure, and plug-in bosses are fixed on the upper and lower sides of the plug-in plate; the plug-in plate and the plug-in bosses are respectively inserted into the plug-in groove and the limit groove.

[0008] As a further solution of the utility model: the thickness of the high wear-resistant rubber sheet is greater than the shallow groove, so that it can first contact the surface of other objects, thereby reducing the friction consumption of the magnet body.

[0009] As a further solution of the utility model: the four sides of the magnetic protrusion block are equal in length.

[0010] Compared with the prior art, the utility model has the following advantages: 1. The utility model adds an elastic support and a magnetic protrusion block structure. When the flexible magnetic plate body is bent, the magnetic protrusion block on one side of the flexible magnetic plate body will come into contact. The magnetic protrusion blocks in contact with each other will prevent the flexible magnetic plate body from bending too much, thereby reducing the bending amplitude of the flexible magnetic plate body and reducing the possibility of cracking.

[0011] 2. The addition of high wear-resistant rubber sheets can increase the wear resistance coefficient of the surface of the flexible magnetic plate without affecting the magnetic properties of the flexible magnetic plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0021] Combined with Figure 1-4 It can be known that the device includes a flexible magnetic plate body 1, a hollow area 1.1 is opened inside the flexible magnetic plate body 1, and a plurality of elastic pillars 2 are obliquely fixed inside the hollow area 1.1, which can support the surface of the flexible magnetic plate body 1, and a plurality of magnetic protrusions 3 are fixed on the upper and lower sides of the flexible magnetic plate body 1, and a shallow groove 3.1 is opened on the upper side of the magnetic protrusion block 3, and a high-wear-resistant rubber sheet 4 is glued and fixed in the shallow groove 3.1, which can prevent the magnet body from being damaged by friction, and a connecting structure is fixed around the flexible magnetic plate body 1.

[0022] The connection structure includes a groove structure 5 fixed on two adjacent sides of the flexible magnetic plate body 1, and the other two adjacent sides of the flexible magnetic plate body 1 are fixed with a plug-in structure 6; a plug-in groove 5.1 is provided on one side of the groove structure 5, and limit grooves 5.2 are provided on the upper and lower sides of the plug-in groove 5.1; a plug-in board 6.1 is fixed on one side of the plug-in structure 6, and plug-in bosses 6.2 are fixed on the upper and lower sides of the plug-in board 6.1, and the plug-in board 6.1 and the plug-in bosses 6.2 are respectively inserted into the plug-in groove 5.1 and the limit groove 5.2; the thickness of the high wear-resistant rubber sheet 3.1 is greater than that of the shallow groove 3.1, and it can first contact the surface of other objects, thereby reducing the friction consumption of the magnet body; the four sides of the magnetic protrusion block 3 are equal.

[0023] The working principle of the present application is as follows: when the flexible magnet is bent, the edges of several magnetic protrusions 3 will contact each other where an extrusion bend occurs on one side of the flexible magnetic plate body 1, thereby preventing the flexible magnetic plate body 1 from bending too much, thereby reducing the bending fatigue suffered by the flexible magnetic plate body 1 at the bending point, making it less likely to produce cracks, and the highly wear-resistant rubber sheet 4 will also make the flexible magnetic plate body 1 first contact external objects when in use, thereby reducing the friction suffered by the flexible magnetic plate body 1.

In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
