Description

Technical Field

[0001] The utility model belongs to the technical field of annular magnets, and in particular relates to an annular magnet. Background Art

[0002] The composition of magnets is iron, cobalt, nickel and other atoms. The internal structure of the atoms is quite special and they have magnetic moment. Magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals. Magnet types: Shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, magnetic bar magnets, magnetic frame magnets; Property magnets: cobalt magnets, ammonium iron boron magnets (strong magnets), ferrite magnets, aluminum nickel cobalt magnets, iron chromium cobalt magnets; Industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets and so on.

[0003] At present, most of the annular magnets are of an integrated structure. If one part of the annular magnet is damaged during use later, it needs to be replaced as a whole, and it cannot be disassembled and replaced separately, which wastes resources. With the development of science and technology, the current annular magnet adopts a split design. For example, Chinese utility model patent CN217061640U discloses an annular magnet. When the first magnet and the second magnet are installed, the vertical card block is located inside the through slot, and then the card block is bent downward until the card block is engaged with the card slot, so that the first magnet and the second magnet can be fixed to form an annular magnet. If a subsequent magnet is damaged, the user does not need to replace it as a whole. It only needs to use a tool, place the tool at the bottom of the connecting column, and bend the card block upward. This structure is convenient for replacing magnets later, saving resources and thus extending the service life of the annular magnet; when the object is located in the first magnet and the second magnet, the tightness of the clamp is adjusted according to the size of the object. It is only necessary to turn the bolt through the handle to move the clamp toward the object until the clamp clamps the object. This structure makes the annular magnet suitable for installing various objects and is convenient for installing and disassembling objects.

[0004] Although the above-mentioned prior art can more conveniently remove the annular magnet from an object, the installation method is relatively cumbersome, and the clamping block needs to be pried during installation. If the magnetic ring needs to be removed but not replaced, the clamping block is easily broken due to frequent prying, and thus cannot be removed multiple times. Utility Model Content

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 As shown, it is a schematic diagram of a ring magnet structure of a preferred embodiment of the utility model. The ring magnet of this embodiment includes a first magnetic ring 100 and a second magnetic ring 101 that are relatively arranged. The first magnetic ring 100 and the second magnetic ring 101 are snap-fitted together. The first magnetic ring 100 and the second magnetic ring 101 are adsorbed and located outside the installation object through magnetic attraction. When disassembling, the first magnetic ring 100 and the second magnetic ring 101 can be separated by moving them to both sides, so that they can be disassembled and installed more conveniently.

[0030] like Figure 2 As shown, it is a schematic diagram of the structure of the first magnetic ring and the second magnetic ring in this embodiment, the outer walls of the two side ends of the first magnetic ring 100 are provided with trapezoidal grooves 102, and the outer walls of the two side ends of the second magnetic ring 101 are provided with trapezoidal protrusions 103 plugged into the trapezoidal grooves 102. In this embodiment, when the first magnetic ring 100 and the second magnetic ring 101 are fitted together, the trapezoidal protrusions 103 are inserted into the trapezoidal grooves 102, so that the first magnetic ring 100 and the second magnetic ring 101 can be more conveniently adsorbed, so that the contact area between the first magnetic ring 100 and the second magnetic ring 101 is larger, so that the adsorption is tighter.

[0031] like Figure 3 as well as Figure 4As shown, it is a schematic diagram of the structure of the first magnetic ring and the second magnetic ring and the sliding plate and the connecting plate in this embodiment. The upper and lower ends of the first magnetic ring 100 and the second magnetic ring 101 are both provided with second sliding grooves 105. The two ends of each second sliding groove 105 penetrate the first magnetic ring 100 and the second magnetic ring 101. The interior of each second sliding groove 105 is slidably connected with a sliding plate 201. Each second sliding groove 105 is provided with a through groove 109 connected to the outside. The outer wall of each second sliding groove 105 is provided with a protrusion 202 that penetrates the through groove 109. In this embodiment, the upper or lower first magnetic ring 100 or the second magnetic ring 101 is rotated. A protrusion 202 in one magnetic ring 100 or the second magnetic ring 101 allows the sliding plate 201 to rotate, and then can be inserted into the second sliding groove 105 in the first magnetic ring 100 or the second magnetic ring 101 on the other side, and at the same time, the sliding plate 201 inside the first magnetic ring 100 or the second magnetic ring 101 on the other side is rotated to the inside of the first magnetic ring 100 or the second magnetic ring 101 on one side, so that the first magnetic ring 100 and the second magnetic ring 101 can be relatively fixed. When disassembling, it is only necessary to reset the sliding plates 201 on the upper and lower sides to complete the disassembly, making installation and disassembly more convenient.

[0032] like Figure 3 as well as Figure 4 As shown, in order to limit the position by rotating the raised portion 202 on one side of the upper or lower side of the first magnetic ring 100 or the second magnetic ring 101, in this embodiment, a connecting groove 106 is provided between the second sliding grooves 105 on the upper and lower sides of the first magnetic ring 100 and the second magnetic ring 101, and a connecting plate 200 passing through the connecting groove 106 is fixedly connected between each two vertically opposite raised portions 202. Through the connecting plate 200, rotating one of the raised portions 202 can cause the upper and lower sliding plates 201 to rotate simultaneously, thereby limiting the position of the first magnetic ring 100 and the second magnetic ring 101.

[0033] like Figure 3 as well as Figure 5 As shown, it is the first magnetic ring and the second magnetic ring and Figure 4The enlarged structural schematic diagram at point A in the middle shows that in order to limit the sliding plate 201 after rotation, in this embodiment, a first sliding groove 104 is provided at the upper end of the first magnetic ring 100 and the lower end of the second magnetic ring 101, and the protrusions 202 above the first magnetic ring 100 and below the second magnetic ring 101 are fixedly connected to the outside with protrusions 202 that are slidably connected to the inside of the first sliding groove 104, and a limiting plate 204 is rotatably connected to each protrusion 202, and a limiting groove 110 is provided on the inner wall of each first sliding groove 104 near the two ends and the center of the first magnetic ring 100 and the second magnetic ring 101. When limiting, the limiting plate 204 is inserted into the limiting groove 110 near either side of the two ends of the first sliding groove 104 to limit the installation, and when disassembling, the limiting plate 204 is inserted into the limiting groove 110 near the two ends and the center of the two ends of the first magnetic ring 100 and the second magnetic ring 101 to be disassembled.

[0034] like Figure 3 As shown, in order to make the first magnetic ring 100 and the second magnetic ring 101 positioned more accurately when they are relative to each other, in this embodiment, the outer walls of the trapezoidal grooves 102 on both sides of the first magnetic ring 100 are provided with positioning holes 107, and the outer walls of the trapezoidal protrusions 103 on both sides of the second magnetic ring 101 are fixedly connected with positioning magnetic columns 108 inserted into the positioning holes 107. When splicing, the positioning magnetic columns 108 are inserted into the internal magnetic attraction of the positioning holes 107, so that the outlet ends of each two second sliding grooves 105 on the first magnetic ring 100 and the second magnetic ring 101 can be relative to each other, so that the sliding plate 201 can be more easily inserted into the other second sliding groove 105 when rotating.

[0035] It is worth noting that the connecting plate 200 , the sliding plate 201 , the protruding portion 202 , the L-shaped sliding block 203 and the limiting plate 204 are made of non-magnetic materials.
