Description

Technical Field

[0001] This utility model relates to the field of magnetic material application technology, and in particular to a multi-angle adjustable connection structure device for neodymium iron boron permanent magnets. Background Technology

[0002] Neodymium iron boron permanent magnets are widely used in many fields such as electronics, aerospace, and home appliance manufacturing due to their high magnetic properties and cost advantages. They are core components of permanent magnet motors, magnetic separation equipment, loudspeakers, and other products. Currently, the industry mainly uses two methods to connect and assemble neodymium iron boron permanent magnets: epoxy resin bonding and mechanical connection.

[0003] The neodymium iron boron permanent magnet connection structure consists of a positioning groove, a protrusion, and a guide post sleeve forming a positioning structure, an auxiliary permanent magnet forming a magnetic auxiliary structure, and bolts and nuts forming a fixing structure. During connection, the auxiliary permanent magnet attracts the permanent magnet to move closer, the guide post sleeve and the positioning groove protrusion cooperate to position it, and then the bolts are tightened to achieve a tight connection, ensuring the stability of use.

[0004] Current neodymium iron boron permanent magnet connection structures suffer from fixed and cumbersome connection angles, resulting in inefficient and time-consuming operations. Traditional devices typically only achieve connections at specific angles, failing to meet diverse assembly requirements. Changing the connection angle necessitates disassembly and reassembly using additional tools, consuming significant time and manpower. To address these issues, a multi-angle adjustable neodymium iron boron permanent magnet connection structure is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-angle adjustable connection structure device for neodymium iron boron permanent magnets, aiming to improve the problems of fixed and single connection angle, cumbersome operation and inefficiency in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-angle adjustable connection structure device for neodymium iron boron permanent magnets includes a first docking block, a second docking block that is slidably connected inside the first docking block, a fixed box that is fixedly connected to the top of the first docking block, a sliding plate that is slidably connected inside the fixed box, a connecting column that is fixedly connected to the top of the sliding plate, a spring that is sleeved on the outside of the connecting column, a control rod that is fixedly connected to the top of the connecting column, a limiting block that is fixedly connected to the bottom of the sliding plate, and an installation block that is fixedly connected to the front end of the second docking block. An adjustment component is provided inside the installation block.

[0008] As a further description of the above technical solution:

[0009] One end of the spring is fixedly connected to the inside of the fixed box, and the other end of the spring is fixedly connected to the top of the sliding plate;

[0010] As a further description of the above technical solution:

[0011] The mounting block has multiple holes on its exterior, and the limiting block is slidably connected to the interior of the holes on its exterior.

[0012] As a further description of the above technical solution:

[0013] The external of the connecting column is slidably connected to the inside of the fixed box, and the internal of the first docking block is fixedly connected to the second magnet;

[0014] As a further description of the above technical solution:

[0015] The adjustment assembly includes a rotating column, which is rotatably connected to the outside of the mounting block. A shielding plate is fixedly connected to the outside of the rotating column, and a fixed plate is rotatably connected to the outside of the rotating column. A transmission rod is slidably connected to the inside of the rotating column, and a rotating ring is fixedly connected to the outside of the transmission rod.

[0016] As a further description of the above technical solution:

[0017] The rotating ring is externally threaded to the outside of the second docking block, and the transmission rod is externally slidably connected to the inside of the second docking block;

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The shielding plate is externally slidably connected to the inside of the fixed plate, and the inside of the second docking block is provided with a sliding groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, regarding multi-angle rapid docking, when docking is required, pulling the control lever moves the sliding plate and the limiting block. At this time, the magnets attract each other, guiding the second docking block to slide smoothly into the first docking block. After the mounting block is fully slid in, the control lever is released, the spring pushes the sliding plate to reset, and the limiting block accurately engages with the hole of the mounting block, completing a firm docking. At the same time, the angle of the mounting block can be adjusted by rotating the first docking block in advance, so that the limiting block can adapt to different holes and achieve rapid connection at multiple angles. This design does not require complex tools and operations, and can quickly adjust the connection angle according to different usage scenarios, greatly improving connection efficiency and flexibility, and meeting diverse assembly needs.

[0024] 2. In this utility model, regarding magnetic force adjustment, the rotating ring is rotated, and the transmission rod is slidable by the threaded transmission, thereby driving the rotating column and the shielding plate to rotate. The shielding plate is made of a high magnetic permeability material, and its rotation process can change the degree of shielding of the magnetic field of the magnet, thereby adjusting the magnitude of the attraction between magnet one and magnet two. Whether a weak attraction is needed for easy disassembly or a strong attraction is needed to ensure a stable connection, it can be achieved through a simple rotation operation. This adjustment method is convenient to operate and responds quickly. The magnetic force can be flexibly adjusted according to the actual use scenario, enhancing the applicability and reliability of the connection structure under different working conditions.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a multi-angle adjustable connection structure device for neodymium iron boron permanent magnets, including a docking block 1, a docking block 2 slidably connected inside the docking block 1, which can smoothly slide within the docking block 1 to achieve rapid docking and separation, a fixing box 3 fixedly connected to the top of the docking block 1, the internal structure of the fixing box 3 being precision machined to ensure smooth operation of all internal components, a sliding plate 4 slidably connected inside the fixing box 3, the sliding plate 4 having high sliding fit precision within the fixing box 3, and being able to accurately transmit tension and pressure, the top of the sliding plate 4 being fixed. The connecting column 6 is fitted with a spring 7 on its outside. The spring 7 is made of a high-elasticity alloy material and has good resilience. It can quickly return to its original position after being subjected to force. The top of the connecting column 6 is fixedly connected to a control rod 8. The surface of the control rod 8 is provided with anti-slip texture, which makes it easy for the operator to grip and apply force. The bottom of the sliding plate 4 is fixedly connected to a limiting block 5. The limiting block 5 is used to lock the relative position of docking block 1 and docking block 2 to ensure the stability of the connection. The front end of docking block 2 is fixedly connected to a mounting block 9. The mounting block 9 is used to install the adjustment component and provide fixed support for magnet 10.

[0033] The mounting block 9 has an internal adjustment component that can adjust the attraction between magnets and the connection angle. One end of the spring 7 is fixedly connected to the inside of the fixing box 3, and the other end is fixedly connected to the top of the sliding plate 4, so that the spring 7 can provide a restoring force after the sliding plate 4 is moved under force. The mounting block 9 has multiple holes on its outside, which are distributed at a specific angle to provide different locking positions for the limiting block 5. The limiting block 5 is externally slidably connected to the inside of the holes. By cooperating with different holes, multi-angle connection between docking block 1 and docking block 2 can be achieved. The externally slidably connected to the inside of the fixing box 3 ensures that the connecting post 6 can slide stably within the fixing box 3. The docking block 1 has a magnet 2 16 fixedly connected inside. The magnet 2 16 is made of high-performance neodymium iron boron permanent magnet material, which can generate a strong attraction with magnet 1 10 to help achieve a stable connection.

[0034] Reference Figure 1 and Figure 4The adjustment assembly includes a rotating column 11, which is externally rotatably connected to the interior of the mounting block 9 to ensure smooth and wobbly rotation. A shielding plate 13, made of a high-permeability material, is fixedly connected to the outside of the rotating column 11 to effectively shield or weaken the magnetic field between magnets. A fixing plate 12 provides stable rotational support for the rotating column 11, ensuring its stability during rotation. A transmission rod 15 is slidably connected inside the rotating column 11, and a rotating ring 14 is fixedly connected to the outside of the transmission rod 15. The transmission rod 15 transmits the rotational motion of the rotating ring 14 to the rotating column 11. The outer surface of the rotating ring 14 is provided with anti-slip threads. The rotating ring 14 is manually rotated by the operator. Its external thread is connected to the outside of the docking block 2. The external sliding connection of the transmission rod 15 is connected to the inside of the docking block 2, ensuring that the transmission rod 15 can slide smoothly within the docking block 2. The external fixed connection of the fixing plate 12 is connected to the inside of the mounting block 9, providing a stable mounting base for the adjustment assembly. Multiple magnets 10 are fixedly connected inside the mounting block 9. The magnets 10 and magnets 16 cooperate with each other to generate the magnetic force required for connection. The external sliding connection of the shielding plate 13 is connected to the inside of the fixing plate 12, allowing the shielding plate 13 to rotate flexibly within the fixing plate 12. The docking block 2 has a groove inside, providing a guide path for the sliding of the transmission rod 15.

[0035] Working principle: When the operator uses docking block 2 to dock with docking block 1, first pull the control lever 8. The control lever 8 will pull the sliding plate 4 to slide inside the fixed box 3 through the connecting column 6, so that the limiting block 5 slides inside the fixed box 3. At this time, magnet 10 and magnet 2 16 will attract each other. When the outside of the mounting block 9 is completely slid into the inside of docking block 1, release the control lever 8. The spring 7 will automatically push the sliding plate 4 to slide in the opposite direction inside the fixed box 3, so that the outside of the limiting block 5 can slide into the temporal part of the mounting block 9, thus docking docking block 2 with docking block 1. The operator can also first rotate docking block 1 until the mounting block 9 is rotated to a suitable angle, and then release the control lever 8. The limiting block 5 will slide to different holes on the outside of the mounting block 9, so that docking block 1 and docking block 2 can be quickly docked at different angles to meet different usage scenarios.

[0036] The operator can rotate the rotating ring 14 to make the transmission rod 15 slide inside the docking block 2, so that the rotating column 11 rotates inside the docking block 2, thereby making the shielding plate 13 rotate inside the fixed plate 12. The rotation of the shielding plate 13 will adjust the attraction between magnet 10 and magnet 2 16 to adapt to different usage scenarios.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
