[0002] A magnetic field coil is a device that generates a magnetic field. It is usually made of wires made of conductive material. When the current through the coil changes, according to Faraday's law of electromagnetic induction, the coil itself will generate an induced electromotive force to oppose the change in current. This characteristic has important applications in many electromagnetic devices. By using modular magnetic field coils, they can be flexibly assembled according to different magnetic field requirements, which is convenient for installation and maintenance. However, traditional modular magnetic field coils are difficult to control precisely, cannot adapt to diverse needs, have limited heat dissipation methods, and are susceptible to external interference. To meet the requirements of modern magnetic field coils, a new type of modular magnetic field coil is used.

[0026] Reference Figures 1-3 An embodiment of this utility model provides a combined magnetic field coil, including a coil box 1. The inner wall of the coil box 1 has a first ventilation hole 11. A limit block 12 is fixedly connected to the outer wall of the coil box 1. A lead screw 13 is threadedly connected to the inner wall of the limit block 12. A handle 14 is fixedly connected to the outer wall of the lead screw 13. The left outer wall of the handle 14 is rotatably connected to the right outer wall of the limit block 12. A rotating bracket 15 is threadedly connected to the outer wall of the rotating bracket 15. A locking block 16 is fixedly connected to the outer wall of the rotating bracket 15.

A coil body 18 is provided on the inner wall of the coil box 1. A slider 19 is fixedly connected to the outer wall of the coil box 1. A bearing component is provided on the outer wall of the slider 19.
[0027] Specifically, the coil box 1 containing the coil body 18 is placed into the support block 2. By rotating the handle 14, the lead screw 13 is rotated. The lead screw 13 drives the rotating bracket 15 to unfold, pushing the locking block 16 and causing the first spring 17 to undergo elastic deformation. The movement of the locking block 16 can fix the limiting block 12 in a slot opened on the support block 2, thereby achieving the effect of adjusting the coil position. The slider 19 is set on the coil box 1, which can make the coil box 1 more stable when adjusting the position. The first ventilation hole 11 is opened on the inner wall of the coil box 1, which can achieve the effect of ventilation and heat dissipation. This component can not only achieve the effect of quickly installing the magnetic field coil, but also adjust the position of the coil, which is suitable for different situations.
[0028] Reference Figure 1 and Figure 4 The supporting component includes a supporting block 2, the inner wall of the supporting block 2 is slidably connected to the outer wall of the slider 19, the inner wall of the supporting block 2 is provided with a groove 21, and the outer wall of the slider 19 is slidably connected to the inner wall of the groove 21; the upper surface of the supporting block 2 is provided with an upper cover 22, the lower surface of the upper cover 22 is fixedly connected with a protrusion, the shape of the protrusion is the same as that of the groove 21, the protrusion is slidably connected to the inner wall of the groove 21, the lower surface of the supporting block 2 is fixedly connected with a base plate 23, the inner wall of the upper cover 22 is provided with a second ventilation hole 24, the shape of the second ventilation hole 24 is the same as that of the first ventilation hole 11, and the upper surface of the base plate 23 is provided with a locking component;
[0029] Specifically, a protrusion is provided on the lower surface of the upper cover 22, which enables the upper cover 22 to stay stably on the upper surface of the support block 2. The sliding groove 21 allows the coil box 1 to slide more stably on the inner wall of the support block 2, and also achieves a fixing effect. The base plate 23 achieves the effect of supporting the overall structure.
[0030] Reference Figure 1 , Figure 5 and Figure 6 The locking assembly includes a threaded rod 3, the outer wall of which is rotatably connected to the inner wall of the base plate 23. A handle 31 is fixedly connected to the upper end of the threaded rod 3, and a lifting ring 32 is threadedly connected to the outer wall of the threaded rod 3. A drive sleeve 33 is fixedly connected to the inner wall of the lifting ring 32. A second spring 34 is provided on the lower surface of the drive sleeve 33, and the outer wall of the second spring 34 is provided on the upper surface of the base plate 23. A driven rod 35 is slidably connected to the inner wall of the drive sleeve 33, and the lower end of the driven rod 35 is rotatably connected to the inner wall of the base plate 23. A moving block 36 is fixedly connected to the outer wall of the driven rod 35, and the outer wall of the moving block 36 is slidably connected to the inner wall of the drive sleeve 33. A lower pressing block 37 is fixedly connected to the upper surface of the driven rod 35, and the lower surface of the lower pressing block 37 is slidably connected to the upper surface of the upper cover 22.
[0031] Specifically, rotating the handle 31 drives the threaded rod 3 to rotate, causing the lifting ring 32 to move up and down. The lifting ring 32 drives the drive sleeve 33 to move, causing the second spring 34 to undergo elastic deformation. At the same time, it can drive the moving block 36 to slide, thereby enabling the driven rod 35 to rotate. Through the rotation of the driven rod 35, the lower pressure block 37 can rotate, thereby enabling the lower pressure block 37 to lock or release the upper cover 22. This component can quickly open the carrier box and put in or take out a certain number of coils.
[0032] Working principle: When the device is needed, rotating the handle 31 drives the threaded rod 3 to rotate on the inner wall of the base plate 23, causing the lifting ring 32 to move up and down. Simultaneously, the movement of the lifting ring 32 drives the drive sleeve 33 to move. The movement of the drive sleeve 33 drives the moving block 36, causing the driven rod 35 to rotate. This causes the second spring 34 to undergo elastic deformation. The rotation of the driven rod 35 drives the lower pressure block 37 to rotate. The rotation of the lower pressure block 37 locks or unlocks the top cover 22. This assembly allows for quick opening of the carrier box, enabling the insertion or removal of coils as needed. The required number of coil boxes 1 containing coil bodies 18 are placed into the carrier block 2. The top cover 22 is closed. By inserting the protruding part of the top cover 22 into the sliding groove 21, the sliding of the top cover 22 on the inner wall of the carrier block 2 becomes more stable. The slider 19 and the limiting block 12 on the coil box 1 are aligned with the slots on the carrier block 2 and inserted. When the coil is adjusted to the designated position, rotating the handle 14 drives the lead screw 13 to rotate. While the rotating bracket 15 unfolds on the inner wall of the limiting block 12, the first spring 17 undergoes elastic deformation. The rotating bracket 15 extends and pushes the locking block 16 into the sliding groove 21 opened on the bearing block 2, thereby achieving the effect of fixing the coil body 18 in the coil box 1. By opening the first ventilation hole 11 on the coil box 1 and the second ventilation hole 24 on the top cover 22, the coil can be cooled. This component can not only achieve the effect of quickly installing the magnetic field coil, but also adjust the position of the coil, making it suitable for different situations. This coil not only solves the problem that the position of the magnetic field coil is difficult to change under the traditional installation method, and if adjustment is required, it is necessary to disassemble, install, or even redesign the bearing structure, which increases the difficulty of operation, wastes time and resources, and cannot flexibly adapt to different situations, but also requires the use of specific tools to disassemble and install the coil, increasing the workload of workers. It also solves the problem that using bolts to seal the carrier of the bearing coil requires a lot of time and effort from workers.
