Description

Technical Field

[0001] The utility model relates to the technical field of magnet processing, in particular to a structure for preventing magnet from falling off. Background Technique

[0002] Magnet generally refers to aluminum-nickel-cobalt alloy. Magnet is synthesized by several hard and strong metals, such as iron combined with aluminum, nickel, cobalt, etc., and sometimes copper, niobium, tantalum are synthesized to make super-hard permanent magnet alloys; due to different compositions of its metal components, its magnetic properties are different, and thus its uses are also different. It is mainly used in various fields such as sensors, instruments, electronics, electromechanics, medical treatment, teaching, automobiles, aviation, military technology, etc. Aluminum-nickel-cobalt magnet is the oldest kind of magnet and is called a natural magnet by people. Although it is the oldest, its excellent adaptability to high temperature makes it still one of the most important magnets today. Aluminum-nickel-cobalt can work normally at a high temperature above 500 °C, which is its greatest feature. In addition, its corrosion resistance is also stronger than that of other magnets.

[0003] Conventional magnets use a structure with a certain interference size and are connected and fixed by a tightly inserted structure with the stator. On the one hand, this structure may damage the magnet during the installation and combination process. On the other hand, this structure is not convenient for structural disassembly, and when facing structural maintenance, it may damage both the magnet and the stator simultaneously.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and its deficiencies, and a structure for preventing magnet from falling off is proposed. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A structure for preventing magnet from falling off, including an outer stator body and a first limiting ring. One end inside the outer stator body is provided with the first limiting ring, and the other end of the outer stator body far from the first limiting ring is provided with a second limiting ring. Moreover, a fastening sleeve is installed in the middle section inside the outer stator body, and a magnet main body is embedded in the inner wall of the fastening sleeve. At the same time, an inner stator body is arranged in the center of the fastening sleeve. The first limiting ring includes an anti-detachment ring, a positioning screw hole, and a fixing bolt. The surface of the anti-detachment ring is provided with the positioning screw hole, and the fixing bolt is installed inside the positioning screw hole.

[0007] Further, the outer stator body includes a stator structure body, a first connection screw hole, and a second connection screw hole. The first connection screw hole is opened on the surface of one end of the stator structure body, and the second connection screw hole is opened on the surface of the other end of the stator structure body far from the first connection screw hole.

[0008] Further, six first connecting screw holes and six second connecting screw holes are both annularly arrayed with the stator structure body as the center, and both the first connecting screw holes and the second connecting screw holes penetrate through the surface of the stator structure body.

[0009] Further, the outer diameter dimension of the anti-detachment ring matches the inner diameter dimension of the stator structure body, and six positioning screw holes and fixing bolts are both annularly arrayed with the anti-detachment ring as the center.

[0010] Further, the fixing bolts are respectively in threaded connection with the first connecting screw holes and the positioning screw holes, and the structures between the first connecting screw holes and the positioning screw holes are interconnected.

[0011] Further, the structure between the second limiting ring and the first limiting ring is the same, and both the first limiting ring and the second limiting ring are movably connected with the outer stator body.

[0012] Further, a slot structure matching the structure of one side surface of the magnet main body is provided on the inner wall surface of the fastening sleeve, and a slot structure matching the structure of the other side surface of the magnet main body is provided on the outer surface of the inner stator body.

[0013] Further, the magnet main body is slidably inserted between the fastening sleeve and the inner stator body, and the first limiting ring and the second limiting ring are used for structurally limiting the fastening sleeve, the magnet main body and the inner stator body.

By using the above structure, on the one hand, the influence on the functions of the whole structural parts can be minimized to avoid causing unnecessary influence on its structure, and on the other hand, the fastening sleeve, the magnet main body and the inner stator body can be stably and effectively provided with the maximum structural limitation to prevent the problem of falling off, thereby improving the combination firmness of the overall structure.
