Description

Technical Field

[0001] This utility model relates to the field of inductors, specifically a multi-layer nested spiral inductor. Background Technology

[0002] A coil is made by winding a wire one turn after another around an insulating tube, with the wires insulated from each other. The insulating tube can be hollow or contain an iron core or a magnetic powder core. An inductor is a device that works by utilizing the principle of electromagnetic induction. A spiral inductor is an inductor element made by winding wires into a spiral shape. It is widely used in electronic circuits for storing magnetic field energy, filtering, tuning, or achieving impedance matching.

[0003] However, current spiral inductors still have some shortcomings. The installation structure of existing spiral inductors is not fully considered. If the installation structure of the spiral inductor is not fully considered during use, it may affect the installation work, making it time-consuming for the staff to install the spiral inductor, or even causing the installation structure to be loose, resulting in the structure becoming loose during subsequent operation, which is inconvenient for the staff to use the spiral inductor.

[0004] The purpose of this invention is to provide a multi-layer nested spiral inductor coil to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer nested spiral inductor coil, comprising a coil body, a connecting assembly, and a fixing base. A fixing rod is provided at the center of the coil body, and blocking rings are provided on the outer sides of both ends of the fixing rod. A locking rod is provided at the end of the fixing rod, and limit rings are fixedly connected to the outer walls of both ends of the locking rod. The connecting assembly is disposed between the fixing rod and the locking rod, and the connecting assembly includes a connecting block, a locking component, a return spring, and a rotating ring. The fixing base is disposed below the coil body, and a fixing plate is provided on one side above the fixing base, and a movable plate is provided on the other side above the fixing base. A moving assembly is disposed below the movable plate, and the moving assembly includes a connecting rod, a square block, a limit screw, a connecting component, a drive motor, a rotating rod, and a locking block.

[0006] Furthermore, the blocking rings are disposed on both sides of the coil body, and an insulating pad is provided at the connection between the blocking rings and the coil body, and the side of the blocking rings is fixedly bonded to the insulating pad.

[0007] Furthermore, the connecting block is welded to the center of one side of the engaging rod, and engaging components are engaged on all four sides of the connecting block. A return spring is provided on the outer side of the bottom end of the engaging component, and the return spring is located inside the fixing rod.

[0008] Furthermore, the outer wall of the end of the fixing rod is provided with an external thread, and the fixing rod is rotatably connected to a rotating ring through the external thread, and the inner wall of the rotating ring is in contact with the top surface of the engaging component.

[0009] Furthermore, both the fixed upright plate and the movable upright plate are rotatably connected to rotating components via damping shafts. The outer walls of the fixed upright plate, the movable upright plate, and the rotating components are all welded with arc-shaped blocks, and the arc-shaped blocks are connected by bolts. Moreover, the locking rod is locked and limited between the fixed upright plate and the rotating component, and between the movable upright plate and the rotating component.

[0010] Furthermore, the connecting rod is disposed on one side of the fixed base, and square blocks are fixedly connected to both ends of the connecting rod.

[0013] This invention provides a multi-layer nested spiral inductor coil, which has the following advantages:

[0014] 1. This utility model is equipped with a connecting component. During the use of the spiral inductor, the rotating ring is rotated, causing the rotating ring to gradually move to the outer side of the end of the engaging component. This makes the engaging component more securely engaged with the connecting block, facilitating the installation of the spiral inductor by the operator. The connection structure is also tight, preventing the structure from loosening during subsequent use and ensuring the smooth operation of the spiral inductor.

[0015] 2. This utility model is equipped with a movable component. During the use of the spiral inductor coil, the rotation of the limiting screw causes the connecting piece connected to the outside of the limiting screw via a threaded rotation to engage and slide on the side of the fixed base. This allows the movable upright plate welded to the side of the connecting piece to move above the fixed base, facilitating the adjustment of the support structure by the operator according to the actual situation of the spiral inductor coil. This makes the installation of the spiral inductor coil more convenient. Furthermore, the motor structure is detachable, preventing the presence of the motor structure from affecting the operation of the spiral inductor coil and facilitating subsequent maintenance and use by the operator.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-3As shown, a multi-layer nested spiral inductor coil includes a coil body 1, a connecting assembly 6, and a fixing base 7. A fixing rod 2 is located at the center of the coil body 1, and blocking rings 3 are located on the outer sides of both ends of the fixing rod 2. The blocking rings 3 are located on both sides of the coil body 1, and an insulating pad is provided at the connection between the blocking rings 3 and the coil body 1. The sides of the blocking rings 3 are fixedly adhered to the insulating pads. A locking rod 4 is located at the end of the fixing rod 2, and limit rings 5 ​​are fixedly connected to the outer walls of both ends of the locking rod 4. The connecting assembly 6 is located between the fixing rod 2 and the locking rod 4. The connecting assembly 6 includes a connecting block 601, a locking member 602, a return spring 603, and a rotating ring 604. The connecting block 601 is welded to the center of one side of the locking rod 4, and the locking member 602 is engaged on all four sides of the connecting block 601. The return spring 603 is provided on the outer side of the bottom end of the locking member 602, and the return spring 603 is located inside the fixing rod 2. The outer wall of the end of the fixing rod 2 is provided with an external thread, and the fixing rod 2 is rotatably connected to the rotating ring 604 through the external thread. The inner wall of the rotating ring 604 is in contact with the top surface of the locking member 602.

[0023] The specific operation is as follows: the coil body 1 adopts a multi-layer nested spiral structure, which can increase the number of coil turns in a limited space, thereby increasing the inductance. When using the multi-layer nested spiral inductor coil, the operator uses the connecting component 6 to install the locking rod 4 at the end of the fixing rod 2, and inserts the connecting block 601 fixed at the center of one end of the locking rod 4 into the end of the fixing rod 2. Then, the operator presses the locking part 602, so that the lower end of the locking part 602 engages with the connecting block 601, and the return spring 603 set on the outside of the locking part 602 is compressed. At the same time, the operator uses the external thread on the outer wall of the end of the fixing rod 2 to rotate the rotating ring 604, so that the rotating ring 604 gradually moves to the outside of the end of the locking part 602, thereby stabilizing and limiting the locking part 602. Subsequently, the elastic force of the return spring 603 can be used to separate the locking part 602 from the connecting block 601, thereby facilitating the separation of the locking rod 4 from the fixing rod 2, making it convenient for the operator to use the spiral inductor coil.

[0024] like Figure 1 and Figure 4As shown, the fixed base 7 is located below the coil body 1, and a fixed upright plate 8 is provided on one side of the upper part of the fixed base 7, while a movable upright plate 9 is provided on the other side of the upper part of the fixed base 7. A rotating component 10 is rotatably connected to the upper part of both the fixed upright plate 8 and the movable upright plate 9 via a damping shaft. Arc-shaped blocks 11 are welded to the outer walls of the fixed upright plate 8, the movable upright plate 9, and the rotating component 10, and are connected by bolts. A locking rod 4 engages and limits the connection between the fixed upright plate 8 and the rotating component 10, and between the movable upright plate 9 and the rotating component 10. A moving assembly 12 is located below the movable upright plate 9. The moving assembly 12 includes a connecting rod 1201, a square block 1202, a limiting screw 1203, a connecting component 1204, a drive motor 1205, a rotating rod 1206, and a locking block 1207. The connecting rod 1201 is located on one side of the fixed base 7, and the connecting rod 1201... A square block 1202 is fixedly connected to both ends of the fixed base 7, and a limiting screw 1203 is provided on the other side of the fixed base 7. The end of the limiting screw 1203 is rotatably connected to the square block 1202. The side of the square block 1202 is welded to the side of the fixed base 7. A connecting piece 1204 is connected through the outer side of the connecting rod 1201. The outer side of the limiting screw 1203 is rotatably connected to the connecting piece 1204 by a thread. The connecting piece 1204 is engaged and slidably connected to the side of the fixed base 7. The connecting piece 1204 is welded to the side of the movable upright plate 9. A drive motor 1205 is provided on one side of the square block 1202. The output shaft of the drive motor 1205 is fixedly connected to a rotating rod 1206 through a coupling. A locking block 1207 is welded to the end of the rotating rod 1206. The rotating rod 1206 is engaged and connected to the end of the limiting screw 1203 through the locking block 1207.

[0025] The specific operation is as follows: The operator engages the locking rod 4 above the fixed plate 8 and the movable plate 9, and rotates the rotating part 10 that is rotatably connected above the fixed plate 8 and the movable plate 9, so that the locking rod 4 is firmly limited. Then, the arc-shaped blocks 11 are fixed together with bolts. During this process, the operator can adjust the position of the movable plate 9 using the moving component 12. The locking block 1207 engages the rotating rod 1206 with the limiting screw 1203. Then, the drive motor 1205 drives the rotating rod 1206 to rotate, so that the limiting screw 1203 rotates accordingly. This causes the connecting part 1204, which is connected to the outside of the limiting screw 1203 by a thread, to engage and slide on the side of the fixed seat 7, thereby allowing the movable plate 9, which is welded to the side of the connecting part 1204, to move above the fixed seat 7. In addition, the connecting part 1204 on the other side moves through the outside of the connecting rod 1201 to ensure the stability of the movement of the movable plate 9 and facilitate the operator's use of the spiral inductor coil.

[0026] In summary, this multi-layer nested spiral inductor coil, according to Figures 1-4 The structure shown illustrates that, during the use of the spiral inductor, the coil body 1 employs a multi-layered nested spiral structure, which increases the number of coil turns within a limited space, thereby enhancing the inductance. When using the multi-layered nested spiral inductor, the operator uses the connecting component 6 to install the engaging rod 4 at the end of the fixing rod 2. The connecting block 601, fixed at the center of one end of the engaging rod 4, is then inserted into the end of the fixing rod 2. The operator then presses the engaging piece 602, causing its lower end to engage with the connecting block 601, and compressing the return spring 603 located on the outer side of the engaging piece 602. Simultaneously, the operator uses the external thread on the outer wall of the fixing rod 2 to rotate the rotating ring 604, causing it to gradually move to the outer side of the engaging piece 602, thus securing and limiting the engaging piece 602. Subsequently, the elastic force of the return spring 603 can be used to separate the engaging piece 602 from the connecting block 601, facilitating the connection between the engaging rod 4 and the fixing rod 2. After separation, the operator engages the locking rod 4 above the fixed plate 8 and the movable plate 9, and rotates the rotating component 10 connected to the fixed plate 8 and the movable plate 9 to securely limit the locking rod 4. Then, bolts are used to fix the arc-shaped blocks 11 together. During this process, the operator can use the moving component 12 to adjust the position of the movable plate 9. The locking block 1207 engages the rotating rod 1206 with the limiting screw 1203. Then, the drive motor 1205 drives the rotating rod 1206 to rotate, causing the limiting screw 1203 to rotate accordingly. This causes the connecting component 1204, which is connected to the limiting screw 1203 by a thread, to engage and slide on the side of the fixed seat 7. This allows the movable plate 9, which is welded to the side of the connecting component 1204, to move above the fixed seat 7. In addition, the connecting component 1204 on the other side moves through the connecting rod 1201 to ensure the stability of the movable plate 9's movement, facilitating the operator's use of the spiral inductor coil.
