Description

Technical Field

[0001] This utility model relates to the field of ferrite magnet technology, and in particular to a high-strength ferrite magnet. Background Technology

[0002] Ferrite magnets, also known as permanent magnet ferrites, are mainly composed of iron oxide, barium carbonate, or strontium carbonate. After being magnetized, they have a very high residual magnetic field strength and can maintain the residual magnetic field for a long time. They are commonly used as permanent magnet materials.

[0003] The existing Chinese utility model patent with publication number CN220291744U discloses a high-strength ferrite magnet. This utility model includes: a protective component for protecting the ferrite magnet; a magnet body for use is fixedly installed on the inner surface of the protective component; and a reinforcing component for increasing the magnetic force of the ferrite magnet is fixedly installed on one side of the magnet body. The beneficial effects of this utility model are: by connecting the reinforcing component to one side of the magnet, which is made of high-manganese steel, the magnetic force of the ferrite magnet is effectively increased, as is the surface hardness and wear resistance of the ferrite magnet. Connecting the reinforcing component to one side of the magnet body, to a certain extent, avoids the weakening of the magnetic force of the ferrite magnet, thus facilitating the high-strength use of the ferrite magnet.

[0004] However, existing ferrite magnets do not solve the problem of magnetic force weakening at high temperatures during use. At the same time, the existing protective structure is not convenient to disassemble and assemble, which affects later inspection and maintenance. Utility Model Content

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] A high-strength ferrite magnet includes a magnet body and a storage box for storing the magnet body. A circular through slot is formed at the center of the bottom of the storage box. An annular frame is fixedly connected to the center of the inner cavity of the storage box. A first buffer layer is provided at the bottom of the inner cavity of the annular frame. The magnet body is disposed in the inner cavity of the annular frame and is fitted against the top of the first buffer layer. A second buffer layer is fitted against the top of the magnet body, and a snap-fit ​​mechanism is provided at the top of the second buffer layer.

[0007] Furthermore, the snap-fit ​​mechanism includes an annular pressure plate, which is fitted to the top of the second buffer layer. The storage box has four rectangularly arrayed cavities near its top, and each cavity has a corresponding limiting plate slidably connected to its inner cavity. A T-shaped rod is fixedly fixed through each limiting plate. Each cavity has a first through hole on its two axially opposite sides to the T-shaped rod, which is adapted to the T-shaped rod. The longest end of each T-shaped rod passes through the inner cavity of an adjacent first through hole and is fitted to the top of the annular pressure plate. The shortest end of each T-shaped rod passes through the inner cavity of an adjacent first through hole and extends to the outside of the storage box. A first spring is sleeved on the outside of each T-shaped rod, and both ends of the first spring are fixedly connected to the inner wall of the cavity and the limiting plate, respectively.

[0008] Furthermore, an annular partition is fitted and fixed at the top of the outer wall of the annular frame, and the annular partition is fitted to the second buffer layer.

[0009] Furthermore, a number of ventilation holes are evenly distributed on the outer wall of the annular frame.

[0010] Furthermore, the outer wall of the storage box has four fixing holes arranged in a rectangular array, and the inner cavity of each fixing hole is slidably connected to a matching circular plate. Each circular plate has a rubber ring fitted and fixed on its outer wall. Each fixing hole has a U-shaped plate on its inner side, and a crossbar slides through the U-shaped plate. One end of the crossbar is fixedly connected to an adjacent circular plate, and the other end of the crossbar is fixedly connected to a connecting plate. Each crossbar has a second spring fitted on its outer wall, and the two ends of the second spring are fixedly connected to the U-shaped plate and the connecting plate, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By placing the magnet body in the annular frame and using the first buffer layer, second buffer layer, annular pressure plate, T-shaped rod, limiting plate and first spring, the magnet body can be locked in the vertical direction, thereby avoiding friction on the surface of the ferrite magnet and increasing the high strength of the ferrite magnet.

[0013] 2. Through the design of vents, fixing holes, a circular plate, a rubber ring, a crossbar, a U-shaped plate, a connecting plate, and a second spring, when the temperature of the magnet body rises, the vents can transfer heat to the inner cavity of the storage box. After the airflow enters the inner cavity of the fixing hole, it can push the circular plate to overcome the resistance of the second spring and extend to the outside of the storage box, thereby dissipating the heat from the fixing hole to the outside. This achieves the function of self-heating of the magnet body and prevents the magnet body temperature from rising and affecting the magnetic effect. Attached Figure Description

Detailed Implementation

[0020] Please see Figures 1 to 5 The present invention provides the following technical solution:

[0021] A high-strength ferrite magnet includes a magnet body 1 and a storage box 2 for storing the magnet body 1. A circular through groove is provided at the center of the bottom of the storage box 2. An annular frame 3 is fixedly connected to the center of the inner cavity of the storage box 2. A first buffer layer 4 is provided at the bottom of the inner cavity of the annular frame 3. The magnet body 1 is disposed in the inner cavity of the annular frame 3 and is attached to the top of the first buffer layer 4. A second buffer layer 6 is attached to the top of the magnet body 1, and a snap-fit ​​mechanism is provided at the top of the second buffer layer 6.

[0022] The snap-fit ​​mechanism includes an annular pressure plate 7, which is fitted to the top of the second buffer layer 6. Four rectangular array-shaped cavities are formed near the top of the storage box 2. Each cavity has a corresponding limiting plate 8 slidably connected to its inner cavity. A T-shaped rod 9 is fixedly inserted through each limiting plate 8. Each cavity has a first through hole on its two axially opposite sides to the T-shaped rod 9, which is adapted to the T-shaped rod 9. The longest end of each T-shaped rod 9 passes through the inner cavity of the adjacent first through hole and is fitted to the top of the annular pressure plate 7. The shortest end of each T-shaped rod 9 passes through the inner cavity of the adjacent first through hole and extends to the outside of the storage box 2. A first spring 10 is fitted on the outside of each T-shaped rod 9, and both ends of the first spring 10 are fixedly connected to the inner wall of the cavity and the limiting plate 8, respectively. By fitting the T-shaped rod 9 to the top of the annular pressure plate 7, the annular pressure plate 7 can be tightly pressed against the top of the second buffer layer 6, thus working with the first buffer layer 4 to buffer and protect the magnet body 1.

[0023] An annular partition 5 is fitted and fixed at the top of the outer wall of the annular frame 3, and the annular partition 5 is fitted with the second buffer layer 6 to provide vertical support for the second buffer layer 6 and improve the flatness of the second buffer layer 6.

[0024] Several ventilation holes 11 are evenly distributed on the outer wall of the ring frame 3, which can discharge the heat of the magnet body 1 into the inner cavity of the storage box 2 through the ventilation holes 11.

[0025] The outer wall of the storage box 2 has four fixed holes 12 arranged in a rectangular array. The inner cavity of the fixed holes 12 is slidably connected to a matching circular plate 13. A rubber ring 14 is fixedly fitted on the outer wall of each circular plate 13. A U-shaped plate 16 is provided on the inner side of each fixed hole 12. A crossbar 15 slides through the U-shaped plate 16. One end of the crossbar 15 is fixedly connected to the adjacent circular plate 13, and the other end of the crossbar 15 is fixedly connected to a connecting plate 17. A second spring 18 is fitted on the outer wall of each crossbar 15. The two ends of the second spring 18 are fixedly connected to the U-shaped plate 16 and the connecting plate 17, respectively. When the heat inside the storage box 2 is too high, airflow flows into the inner cavity of the fixed holes 12 and pushes the circular plate 13 to move outward against the resistance of the second spring 18. This allows the heat inside the storage box 2 to be discharged from the fixed holes 12, improving the heat dissipation performance of the magnet body 1.

[0026] Working principle: In use, the magnet body 1 is placed into the inner cavity of the annular frame 3 of the storage box 2 and attached to the top of the first buffer layer 4. Then, the second buffer layer 6 is placed on top of the magnet body 1 and attached to the top of the annular partition 5. Subsequently, the annular pressure plate 7 is pressed tightly on the top of the second buffer layer 6. When the four T-shaped rods 9 are released in sequence, the longest end of the T-shaped rods 9 can be extended to the top of the annular pressure plate 7 under the action of the rebound force of the first spring 10, thereby locking the annular pressure plate 7. When the temperature of the magnet body 1 rises, the heat can be transferred to the storage box 2 through the ventilation hole 11, which increases the air pressure in the storage box 2 and pushes the circular plate 13 and the rubber ring 14 to move outward against the resistance of the second spring 18, thereby opening the fixing hole 12. Then, the heat accumulated in the inner cavity of the storage box 2 can be discharged through the fixing hole 12, improving the self-heating performance of the magnet body 1.
