Technical Field

[0001] The utility model relates to the technical field of Al-Ni-Co magnets, in particular to a combined Al-Ni-Co magnet with a protective piece. Background Art

[0002] Alnico magnets refer to substances or materials that can generate magnetic fields. Due to their unique magnetism, they are widely used in modern industry and electronic technology. At the same time, because magnetic materials can be well attached to iron products, magnets are also increasingly used in daily life, such as shielding workwear and office supplies. One of the most common problems is how to effectively connect magnets to other objects. The existing technology generally involves pasting or directly wrapping the magnets in objects, which is not stable enough. In addition, for combined Alnico magnets, Alnico magnets lack protective parts, which makes them prone to breakage when they are unstable when dropped or hit.

[0003] Patent application number 201820109408.6 discloses an aluminum-nickel-cobalt high-temperature resistant magnet, including a magnet body, wherein a square groove and a cylindrical groove are respectively provided inside the magnet body, wherein the bottom of the square groove is connected to the top of the cylindrical groove, wherein a wear-resistant layer is fixedly connected inside the square groove, wherein a movable block is movably connected inside the wear-resistant layer, wherein a screw is fixedly connected to the bottom of the movable block, wherein the bottom end of the screw passes through the wear-resistant layer, the square groove and the cylindrical groove in sequence and extends to the outside of the cylindrical groove. The magnet body, the square groove, the cylindrical groove, the wear-resistant layer, the movable block and the screw are used in coordination.

[0004] However, this technical solution uses screws to fix the magnet body on the device, but it is difficult to combine and fix multiple magnet bodies together in actual use, and the magnet body is still prone to breakage and damage when it is hit. Utility Model Content

[0012] Furthermore, the positioning plate is slidably inserted in the telescopic slot, and an anti-slip portion abutting against the inner wall of the telescopic slot is fixed on the positioning plate.

[0013] Furthermore, springs are embedded in both ends of the telescopic slot, and a magnetic rod fixed to the electromagnetic plate is fixed on the anti-slip portion.

[0014] The beneficial effects of the utility model are:

[0015] (1) In the utility model, the AlNiCo magnet body is embedded and fixed in the combined magnet, and the combined magnet wraps the AlNiCo magnet body for protection. At the same time, multiple arc-shaped combined magnets are inserted into the connecting groove through the damping of the connecting block and are connected end to end to be fixed to each other, which facilitates the combination and fixation of the multiple combined magnets and improves the convenience of combining the AlNiCo magnet bodies with each other.
