[0002] An adjustable inductor is an electronic component whose inductance can be manually adjusted. It is widely used in circuits for tuning, filtering, and impedance matching. However, existing adjustable inductors often adjust their inductance by changing the number of turns connected, which only allows for relatively coarse adjustments and affects the overall performance. Utility Model Content

[0003] This utility model addresses the problems of limited adjustment methods and difficulty in accurately adjusting inductance in existing technologies by proposing the following technical solution: An adjustable inductor includes a protective housing, wherein an inner frame assembly is rotatably connected to the inner surface of the protective housing. The inner frame assembly includes a side rotating cylinder rotatably connected to the inner surface of the protective shell. A winding frame is fixedly connected to the left end of the side rotating cylinder. A coil is fixedly connected to the outer surface of the winding frame. A contact end abuts against the front outer surface of the coil. A power-connecting pin is fixedly connected to the front end of the contact end. A sliding block is fixedly connected to the outer surface of the left power-connecting pin. A locking block is fixedly connected to the outer surface of the right power-connecting pin. The outer surface of the sliding block is slidably connected to the inner surface of the protective shell. The outer surface of the locking block is fixedly connected to the inner surface of the protective shell.

[0004] As a preferred embodiment of the above technical solution, an adjusting threaded rod is rotatably connected to the inner surface of the protective shell, the outer surface of the adjusting threaded rod is threadedly connected to the inner surface of the sliding block, the outer surface of the adjusting threaded rod is rotatably connected to the inner surface of the locking block, and a first knob is fixedly connected to the right end of the adjusting threaded rod.

[0005] As a preferred embodiment of the above technical solution, a side cover is fixedly connected to the left end of the protective shell, the right end of the side cover is rotatably connected to the left end of the winding skeleton, a bevel gear is fixedly connected to the right end of the winding skeleton, a bevel gear is meshed with the outer surface of the bevel gear, the right end of the bevel gear is rotatably connected to the inner surface of the protective shell, and a second knob is fixedly connected to the right end of the bevel gear.

[0006] As a preferred embodiment of the above technical solution, an arc-shaped guide plate is fixedly connected to the inner surface of the winding skeleton, a guide strip is slidably connected to the outer surface of the arc-shaped guide plate, the inner end of the guide strip is fixedly connected to the same inner cylinder frame, a magnetic core is fixedly connected to the inner surface of the inner cylinder frame, and a plurality of guide rollers are fixedly connected to the outer surface of the inner cylinder frame, with the outer surface of the guide rollers abutting against the inner surface of the arc-shaped guide plate.

[0007] As a preferred embodiment of the above technical solution, a guide frame is fixedly connected to the inner surface of the winding skeleton, the right end of the guide frame is engaged with the inner surface of the side rotating cylinder, an auxiliary threaded rod is rotatably connected to the inner surface of the guide frame, and a third knob is fixedly connected to the right end of the auxiliary threaded rod.

[0008] As a preferred embodiment of the above technical solution, the outer surface of the auxiliary threaded rod is threadedly connected to an annular frame, the inner surface of the annular frame is rotatably connected to the outer surface of the inner cylinder frame, and the bottom end of the protective shell is fixedly connected to a support frame.

[0009] The beneficial effects of this utility model are as follows: By adjusting the threaded transmission between the threaded rod and the sliding block, turning the first knob can change the position of the sliding block, adjust the number of turns of the coil between the connected power pins, and thus adjust the inductance. Through the meshing transmission of the bevel gear and the bevel gear ring, turning the second knob can drive the winding frame and the coil to rotate. Since the coil is spirally wound, when the winding frame and the coil rotate, the contact surface between the power pin on the right end and the coil will change slightly, which can fine-tune the inductance and improve the overall stability and practicality. Through the threaded transmission of the auxiliary threaded rod and the ring frame, and the rotational connection between the ring frame and the inner cylinder frame, turning the third knob can drive the ring frame to slide left and right under the limit of the auxiliary threaded rod, thereby driving the magnetic core in the inner cylinder frame to slide, thus changing the overall inductance, increasing the adjustable range of the inductance, and improving the overall practicality and functionality. At the same time, through the sliding connection between the guide slide and the arc-shaped guide plate, and the abutment between the guide roller and the arc-shaped guide plate, the sliding wear between the inner cylinder frame and the winding skeleton can be reduced, thereby improving the overall practicality and service life.

A magnetic core is fixedly connected to the inner surface of the inner cylinder frame 16, and several guide rollers 17 are fixedly connected to the outer surface of the inner cylinder frame 16. The rolling action of the guide rollers 17 reduces wear caused by sliding. The outer surface of the guide rollers 17 abuts against the inner surface of the arc-shaped guide plate 14. A guide frame 18 is fixedly connected to the inner surface of the winding frame 202. The right end of the guide frame 18 is engaged with the inner surface of the side rotating cylinder 201. An auxiliary threaded rod 19 is rotatably connected to the surface of the inner cylinder frame 16. A third knob 20 is fixedly connected to the right end of the auxiliary threaded rod 19.

The inner surface of the annular frame 21 is rotatably connected to the outer surface of the inner cylinder frame 16. A support frame 22 is fixedly connected to the bottom end of the protective shell 1 for easy installation and fixation. Through the threaded transmission of the auxiliary threaded rod 19 and the annular frame 21 and the rotatable connection between the annular frame 21 and the inner cylinder frame 16, turning the third knob 20 can drive the annular frame 21 to slide left and right under the limit of the auxiliary threaded rod 19, thereby driving the magnetic core in the inner cylinder frame 16 to slide, thereby changing the overall inductance, increasing the adjustable range of the inductance, and improving the overall practicality and functionality. At the same time, through the sliding connection between the guide slide 15 and the arc-shaped guide plate 14 and the abutment between the guide roller 17 and the arc-shaped guide plate 14, the sliding wear between the inner cylinder frame 16 and the winding skeleton 202 can be reduced, thereby improving the overall practicality and service life.

[0014] like Figures 1 to 8As shown, a coil 3 is fixedly connected to the outer surface of the winding frame 202. A contact end 4 abuts against the front outer surface of the coil 3.

The outer surface of the sliding block 6 is slidably connected to the inner surface of the protective shell 1. The outer surface of the locking block 7 is fixedly connected to the inner surface of the protective shell 1. An adjusting threaded rod 8 is rotatably connected to the inner surface of the protective shell 1. The outer surface of the adjusting threaded rod 8 is threadedly connected to the inner surface of the sliding block 6.

A bevel gear 12 is meshed with the outer surface of the bevel ring 11. The right end of the bevel gear 12 is rotatably connected to the inner surface of the protective shell 1. A second knob 13 is fixedly connected to the right end of the bevel gear 12. By adjusting the threaded transmission between the threaded rod 8 and the sliding block 6, turning the first knob 9 can change the position of the sliding block 6 and adjust the number of turns of the coil 3 connected to the power connection pin 5, thereby adjusting the inductance. Through the meshing transmission between the bevel gear 12 and the bevel ring 11, turning the second knob 13 can drive the winding frame 202 and the coil 3 to rotate. Since the coil 3 is spirally wound, when the winding frame 202 and the coil 3 rotate, the contact surface between the power connection pin 5 at the right end and the coil 3 will change slightly, which can finely adjust the inductance and improve the overall stability and practicality. That is, in use, by turning the first knob 9, the second knob 13 and the third knob 20 respectively, the overall inductance can be finely adjusted within a large range, improving the overall reliability and practicality.
