[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 Figure 1 - Figure 3 An embodiment of this utility model provides a magnetic field coil frame with integrated heat dissipation channels, including a frame 1. Multiple sets of air ducts 2 are opened on the surface of the frame 1. The air ducts 2 opened on the inner arc surface and the outer arc surface of the frame 1 are corresponding, so that air can enter the interior of the frame 1 from the air duct 2 on the outer arc surface, thereby dissipating heat from the electromagnetic coil wound on the surface of the winding seat 4. A cavity is opened on the inner side of the air duct 2, so that air will circulate when it enters the interior of the frame 1 from the outer arc surface. The inner wall of the frame 1 is detachably installed with the winding seat 4 through the limiting component 3. An adjustment component 5 is provided at the top of the winding seat 4.

[0033] Reference Figure 2 and Figure 3The adjusting component 5 includes a concave block 51. A groove is provided at the top of the frame 1. The inner wall of the groove of the frame 1 contacts the concave block 51. The groove at the top of the frame 1 allows the concave block 51 to be inserted into the groove at the top of the frame 1 during installation of the winding seat 4. This allows the winding seat 4 to be disassembled and replaced when it is damaged. A screw 52 is rotatably connected to the surface of the concave block 51. A slider 53 is threadedly connected to the surface of the screw 52. An internal thread groove is provided on the inner side wall of the slider 53. When the screw 52 rotates, the slider 53 will move threadedly on its surface. A connecting rod 54 is fixedly connected to the bottom of the slider 53. When the slider 53 moves threadedly, it will drive the connecting rod 54 to move synchronously with it. A guide groove is provided on the surface of the winding seat 4. The connecting rod 54 passes through and is slidably connected to the inner wall of the guide groove of the winding seat 4.

[0034] Reference Figure 2 and Figure 3 A trapezoidal block 55 is fixedly connected to the end of the connecting rod 54 away from the slider 53. The trapezoidal block 55 is trapezoidal in shape, and the inclined surfaces on both sides match the inclined surfaces on the inner side of the winding block 57. When the connecting rod 54 moves, it will drive the trapezoidal block 55 to move synchronously with it. Guide blocks 56 are fixedly connected to the side walls on both sides of the connecting rod 54. The winding block 57 is slidably connected to the surface of the guide block 56. The inclined surface of the winding block 57 has a guide groove that matches the guide block 56. The guide block 56 can only move on the inner wall of the guide groove of the winding block 57. When the trapezoidal block 55 moves back and forth, it will push the two sets of guide blocks 56 to move in the guide groove of the winding block 57, so that the position of the two sets of winding blocks 57 can be adjusted according to the winding width of the electromagnetic coil. The trapezoidal block 55 is slidably connected to the center of the inner wall of the winding seat 4, and the winding block 57 passes through and is slidably connected to the inner walls on both sides of the winding seat 4.

[0035] Reference Figure 3 and Figure 4 The limiting component 3 includes a rod 33, which is elastically connected to the inner wall of the top of the frame 1 via a return spring 32. One end of the return spring 32 is fixedly connected to the outer wall of the rod 33, and the other end is fixedly connected to the inner wall of the top of the frame 1. The function of the return spring 32 is to automatically reset the position after the lever 31 is moved and the rod 33 is moved. The outer side wall of the concave block 51 is provided with a slot. The outer wall of the rod 33 is inserted into the inner wall of the slot. The insertion between the two can fix the concave block 51 in the position of the inner wall of the groove of the frame 1, thereby fixing the position of the winding seat 4. The top of the outer wall of the rod 33 is fixedly connected to the lever 31. The rod 33 is slidably connected to the inner wall of the top of the frame 1, and the lever 31 is slidably connected to the surface of the top of the frame 1.

[0036] Working principle: When installing the winding seat 4, align the concave block 51 at the top of the winding seat 4 with the groove at the top of the frame 1 and insert it. At the same time, move the lever 31 to drive the insertion rod 33 to move outward on the inner wall of the frame 1 until one end of the concave block 51 is inserted into the groove of the frame 1. Release the insertion rod 33, and it will be inserted into the slot on the outer side wall of the concave block 51 under the action of the return spring 32, fixing the position of the concave block 51 on the inner wall of the groove of the frame 1, thereby fixing the position of the winding seat 4. When a set of winding seats 4 is damaged and needs to be disassembled and replaced, move the lever 31. The lever 31 will drive the insertion rod 33 to move outward against the elastic force of the return spring 32 and disengage from the slot of the concave block 51, so that the winding seat 4 can be removed from the frame 1.

[0037] When the position of the winding block 57 needs to be adjusted according to the winding width of the electromagnetic coil, the screw 52 is rotated. Since the inner sidewall of the slider 53 has an internal thread groove that engages with the screw 52, ​​when the screw 52 rotates, the slider 53 moves threadedly on its surface. The movement of the slider 53 drives the connecting rod 54 to move synchronously. The connecting rod 54 drives the trapezoidal block 55 to move. The trapezoidal block 55 is trapezoidal in shape, and its two inclined surfaces fit with the inner inclined surfaces of the winding block 57. The guide blocks 56 on both sides of the connecting rod 54 slide in the guide groove of the winding block 57. When the trapezoidal block 55 moves, it pushes the two sets of guide blocks 56 to move in the guide groove of the winding block 57, thereby making the two sets of winding blocks 57 move closer or further apart, so as to adjust the position of the winding block 57 according to the winding width of the electromagnetic coil.

[0038] Air enters through the air duct 2 on the outer arc surface of the frame 1. Due to the cavity structure inside the air duct 2, the air can circulate after entering the frame 1. The circulating air can dissipate heat from the electromagnetic coil wound on the surface of the winding base 4, carrying away the heat generated by the electromagnetic coil during operation, ensuring that the electromagnetic coil works in a suitable temperature environment, and improving its performance and service life.

[0039] 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.
