Description

Technical Field

[0001] This utility model relates to the field of ring magnet technology, and in particular to a multi-stage special ring magnet for motors. Background Technology

[0002] Special ring magnets are ring magnets with special properties, structures, or uses. Multipole ring magnets are one type, where the magnetic poles are arranged alternately along the circumference, such as common four-pole, six-pole, and eight-pole configurations. The multipole design makes the magnetic field distribution more complex and specialized, providing a more uniform or directional magnetic field in specific applications. These magnets are often used in motors. In motors, generators, and other equipment, multipole ring magnets can improve motor efficiency and performance, making motor operation smoother.

[0003] The inventors believe that the following defects often exist: the magnet body is continuously used in the motor, but it is not used all the time. There will be idle periods or transportation. When the magnet body is idle, dust falls on the surface of the magnet body, or the magnet body is hit by external objects, causing the magnet body to be covered by dust or damaged, thus affecting the normal use of the magnet body. Therefore, in order to solve the above problems, a multi-stage special ring magnet for motors is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the magnet body is covered by dust or damaged, thus affecting the normal use of the magnet body. Therefore, this invention proposes a multi-stage special ring magnet for motors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage special ring magnet for motors, comprising a magnet body, a placement plate slidably connected to the lower surface of the magnet body, a protective shell slidably connected to the surface of the placement plate, a connecting post fixedly connected to the surface of the placement plate, the arc surface of the connecting post slidably connected to the protective shell, two sliding grooves formed on the surface of the protective shell, an L-shaped frame slidably connected to the inner surface of the sliding grooves of the protective shell, a connecting rod fixedly connected to the surface of the connecting post, a connecting plate fixedly connected to the end of the connecting rod away from the connecting post, and the surface of the connecting plate slidably connected to the L-shaped frame.

[0006] The aforementioned components achieve the following effect: they protect the magnet body, preventing dust from settling on its surface when the magnet body is idle, or from being bumped or knocked by external objects, thus avoiding dust accumulation or damage to the magnet body and preventing any disruption to its normal use. This improves the protective performance of the device.

[0007] Preferably, a fixing rod is fixedly connected to the upper surface of the L-shaped frame, an operating plate is slidably connected to the arc surface of the fixing rod, an insertion rod is fixedly connected to the side of the operating plate near the L-shaped frame, and two insertion holes are opened on the surface of the connecting plate.

[0008] The aforementioned components achieve the following effect: they limit the L-shaped frame, preventing the L-shaped frame from unintentionally sliding within the sliding groove of the protective shell during transport of the magnet body while it is in a protected state, thus forcing the removal of the protection on the magnet body.

[0009] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the L-shaped frame, and the size of the insertion rod is adapted to the size of the insertion hole of the connecting plate.

[0010] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls the operating plate.

[0011] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the operating plate and the L-shaped frame, respectively.

[0012] The effect achieved by the above components is as follows: the first spring improves the stability of the insertion rod when it is positioned on the L-shaped frame, so that when the operator is transporting the magnet body, he / she can ignore the shaking of the magnet body and improve the operator's efficiency in transporting the magnet body.

[0013] Preferably, the inner surface of the magnet body is provided with a weight-reducing groove, and the arc surface of the magnet body is provided with a positioning groove.

[0014] The aforementioned components achieve the following effects: reducing the weight of the magnet body itself, thereby improving its applicability; and the positioning slots facilitate quick installation of the magnet body onto the motor, thus improving the worker's work efficiency.

[0015] Preferably, a soft pad ring is fixedly connected to the arc surface of the connecting column, and the arc surface of the soft pad ring is slidably connected to the magnet body. Four semi-circular pads are fixedly connected to the surface of the placement plate, and the arc surface of the semi-circular pads is slidably connected to the magnet body.

[0016] The effect achieved by the above components is to prevent the magnet body from colliding with the connecting column due to large shaking during transportation, which could cause damage to the magnet body or the connecting column.

[0017] Preferably, the surface of the magnet body is covered with a protective layer, and the protective layer of the magnet body is made of nickel-plated material.

[0018] The effect achieved by the above components is that the nickel-plated material can form a continuous and dense protective film on the surface of the magnet body, preventing corrosive media such as oxygen and moisture from contacting the magnet body.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] This invention achieves the effect of protecting the magnet body, preventing dust from falling on the surface of the magnet body when it is idle, or the magnet body from being bumped by external objects, which would cause the magnet body to be covered by dust or damaged, thus affecting the normal use of the magnet body and improving the protective performance of the device.

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a multi-stage special ring magnet for motors, including a magnet body 1, a placement plate 2 slidably connected to the lower surface of the magnet body 1, a protective shell 3 slidably connected to the surface of the placement plate 2, a connecting post 4 fixedly connected to the surface of the placement plate 2, the arc surface of the connecting post 4 slidably connected to the protective shell 3, two sliding grooves being formed on the surface of the protective shell 3, an L-shaped frame 7 slidably connected to the inner surface of the sliding grooves of the protective shell 3, a connecting rod 5 fixedly connected to the surface of the connecting post 4, a connecting plate 6 fixedly connected to the end of the connecting rod 5 away from the connecting post 4, and the surface of the connecting plate 6 slidably connected to the L-shaped frame 7. When the operator needs to protect the idle magnet body 1, the magnet body 1 is placed on the arc surface of the connecting post 4, and then pressed downwards. Move the magnet body 1 until it adheres to the upper surface of the placement plate 2. Then, place the protective shell 3 onto the arc surface of the connecting post 4 and press it down, causing it to slide downwards along the arc surface of the connecting post 4 until it completely covers the magnet body 1 and adheres to the upper surface of the placement plate 2. Next, push the two L-shaped brackets 7 towards each other, allowing them to slide within the sliding grooves of the protective shell 3 until they completely enclose the connecting plate 6. This achieves the protective effect on the magnet body 1, preventing dust from settling on its surface when idle, or preventing damage from impacts to the magnet body 1, thus ensuring its normal operation. The use of this device improves its protective properties. A fixing rod 8 is fixedly connected to the upper surface of the L-shaped frame 7. An operating plate 9 is slidably connected to the arc surface of the fixing rod 8. An insertion rod 10 is fixedly connected to the side of the operating plate 9 closest to the L-shaped frame 7. Two insertion holes are formed on the surface of the connecting plate 6. When the operator wraps the two L-shaped frames 7 around the connecting plate 6, pressing the operating plate 9 causes it to slide on the arc surface of the fixing rod 8. Simultaneously, the operating plate 9 drives the insertion rod 10 to move until it inserts into the insertion hole of the connecting plate 6. This achieves the effect of limiting the L-shaped frame 7, preventing the magnet body 1 from unintentionally sliding within the sliding groove of the protective shell 3 due to shaking during transport while in a protected state, thus protecting the magnet body 1. When forced release occurs, a limiting plate 11 is fixedly connected to the end of the fixed rod 8 away from the L-shaped frame 7. The size of the insertion rod 10 matches the size of the insertion hole in the connecting plate 6. When the operator pulls the operating plate 9, the operating plate 9 slides on the arc surface of the fixed rod 8. At this time, the limiting plate 11 achieves the effect of limiting the maximum sliding distance of the operating plate 9 on the arc surface of the fixed rod 8, preventing the operating plate 9 from detaching from the arc surface of the fixed rod 8 due to excessive pulling force. A first spring 12 is sleeved on the arc surface of the fixed rod 8. The two ends of the first spring 12 are fixedly connected to the operating plate 9 and the L-shaped frame 7, respectively. When the operator releases the operating plate 9, the rebound force of the first spring 12 causes the operating plate 9 to slide on the arc surface of the fixed rod 8.Simultaneously, the operating plate 9 drives the insertion rod 10 to move until the insertion rod 10 is inserted into the insertion hole of the connecting plate 6. At this time, the first spring 12 improves the stability of the insertion rod 10 when it is limited by the L-shaped frame 7, so that the workers can ignore the shaking of the magnet body 1 when transporting it, thus improving the efficiency of transporting the magnet body 1. The inner surface of the magnet body 1 is provided with a weight-reducing groove 13, and the arc surface of the magnet body 1 is provided with a positioning groove 14, which reduces the weight of the magnet body 1 itself, thereby improving the applicability of the magnet body 1. At the same time, the positioning groove 14 facilitates the workers to quickly install the magnet body 1 on the motor, improving the workers' work efficiency. The circular connecting column 4 A soft pad ring 15 is fixedly connected to the curved surface of the magnet body 1. The curved surface of the soft pad ring 15 is slidably connected to the magnet body 1. Four semi-circular pads 16 are fixedly connected to the surface of the placement plate 2. The curved surfaces of the semi-circular pads 16 are slidably connected to the magnet body 1. This prevents the magnet body 1 from shaking excessively during transportation, which could cause collisions between the magnet body 1 and the connecting post 4, thus avoiding damage to the magnet body 1 or the connecting post 4. The surface of the magnet body 1 is covered with a protective layer made of nickel-plated material. The nickel plating material forms a continuous and dense protective film on the surface of the magnet body 1, preventing contact between the magnet body 1 and corrosive media such as oxygen and moisture.

[0028] Working principle: When the operator needs to protect the idle magnet body 1, the magnet body 1 is placed on the arc surface of the connecting post 4, and the magnet body 1 is pressed down. The positioning groove 14 and the semi-circular pad 16 slide together, and the magnet body 1 slides on the arc surface of the soft pad ring 15 until the magnet body 1 is in contact with the upper surface of the placement plate 2. At this time, the protective shell 3 is placed on the arc surface of the connecting post 4, and the protective shell 3 is pressed down, causing the protective shell 3 to slide downward on the arc surface of the connecting post 4 until the protective shell 3 completely covers the magnet body 1 and is in contact with the upper surface of the placement plate 2. At this time, the operating plate 9 is pulled, causing the operating plate 9 to slide on the arc surface of the fixing rod 8. The first spring 12 is stretched, and at the same time, the operating plate 9 drives the insertion rod 10 to move until the insertion rod 1... The movement of the L-shaped frame 7 is no longer affected. At this time, the two L-shaped frames 7 are pushed to the side closer to each other. The L-shaped frames 7 slide in the sliding groove of the protective shell 3 until the two L-shaped frames 7 wrap around the connecting plate 6. At this time, the operating plate 9 is released. The rebound force of the first spring 12 drives the operating plate 9 to slide on the arc surface of the fixed rod 8. At the same time, the operating plate 9 drives the insertion rod 10 to move until the insertion rod 10 is inserted into the insertion hole of the connecting plate 6. At this time, the magnet body 1 is protected. This prevents dust from falling on the surface of the magnet body 1 when it is idle, or the magnet body 1 from being hit by foreign objects, which would cause the magnet body 1 to be covered by dust or damaged, thus affecting the normal use of the magnet body 1. This improves the protection of the device.
