AI Technical Summary
Existing potentiometers are difficult to use in walkie-talkies to simultaneously achieve volume adjustment and on/off control functions, which cannot meet the requirements of miniaturization design.
A novel potentiometer combining a switch assembly and a rotary adjustment assembly was designed. The control lever drives the shaft cylinder to toggle the switch assembly, and the rotary assembly drives the brush assembly to rotate and adjust the potential. The frictional contact between the spring and the flat washer generates the tactile feedback of the gear position, realizing the turning on and off of the walkie-talkie and the volume adjustment.
It enables the walkie-talkie to be turned on and off, and the volume can be adjusted. It also provides a rotary dial feel, meeting the needs of miniaturized design.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of potentiometer technology, and in particular to a novel potentiometer. Background Technology
[0002] A potentiometer, as an adjustable resistor, adjusts its resistance by changing the position between the moving and fixed contacts on a resistive element. Potentiometers are commonly used in walkie-talkies to adjust the volume. With the increasing miniaturization of electronic products such as walkie-talkies, further requirements are being placed on the potentiometers inside them. These potentiometers are now required to not only adjust the volume but also function as a power switch to turn the walkie-talkie on and off. To address this, we propose a novel potentiometer. Utility Model Content

[0005] The switching assembly includes a shaft cylinder and a switching element that cooperates with the shaft cylinder. The rotation adjustment assembly is provided with a rotating element, and a brush element is installed at the rotating element. The control lever is inserted into the rotating element and the shaft cylinder. When the control lever is rotated, the control lever drives the shaft cylinder to move the switching element, and the rotating element drives the brush element to rotate and adjust the potential at the terminal block.
[0006] To further elaborate, a flat washer is provided between the shaft assembly and the terminal block, the rotating component is located below the flat washer, a stop seat is provided above the flat washer, and the control rod is inserted into the stop seat.
[0007] To further elaborate, a spring is installed at the stop seat, and the flat washer is provided with grooves distributed at equal intervals around the circumference. When the control rod drives the stop seat to rotate, the spring contacts the grooves on the flat washer.
[0008] To further elaborate, the shaft cylinder is provided with a finger portion, and the switch component is provided with a groove that mates with the finger portion of the shaft cylinder.
[0009] To further elaborate, the switch component has a shaft hole, and the shaft hole has a rotating shaft. The upper and lower ends of the rotating shaft are respectively connected to the intermediate connecting seat and the base.
[0010] To elaborate further, rivets are inserted between the base and the shaft assembly.
[0011] The beneficial effects of this utility model are as follows: This utility model adopts a structural design that combines a switch assembly and a rotary adjustment assembly, which can not only control the opening and closing of the walkie-talkie, but also adjust the volume of the walkie-talkie, and can also produce a rotary gear feel when rotating the control lever.

Detailed Implementation
[0018] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0019] Combined with appendix Figure 1 To be continued Figure 5As shown, a novel potentiometer includes a base 10, an intermediate connecting seat 20, and a shaft assembly 30. A rivet 11 passes through the base 10 and the shaft assembly 30. The intermediate connecting seat 20 is located between the base 10 and the shaft assembly 30. A switch assembly is provided between the base 10 and the intermediate connecting seat 20. The switch assembly can control the walkie-talkie to turn on or off. A terminal block 40 is provided between the intermediate connecting seat 20 and the shaft assembly 30. A rotary adjustment assembly is provided between the terminal block 40 and the shaft assembly 30. The rotary adjustment assembly can adjust the volume of the walkie-talkie. A control lever 50 is inserted into the shaft assembly 30.
[0020] Combined with appendix Figure 2 To be continued Figure 5 As shown, the switch assembly includes a shaft cylinder 61 and a switch 62 that cooperates with the shaft cylinder 61. The rotation adjustment assembly includes a rotating component 71, which is specifically located above the shaft cylinder 61. A brush 72 is installed on the rotating component 71, and the brush 72 has brush claws that contact the arc-shaped contact piece in the terminal block 40. The control lever 50 is inserted into both the rotating component 71 and the shaft cylinder 61. When the control lever 50 is rotated, it drives the shaft cylinder 61 to actuate the switch 62, and through the rotating component 71, it drives the brush 72 to rotate and adjust the potential in the terminal block 40. When the control lever 50 is rotated, the rotating component 71 can drive the brush 72, thereby adjusting the potential and thus the volume of the walkie-talkie.
[0021] Combined with appendix Figure 2 To be continued Figure 4 As shown, a flat washer 80 is provided between the shaft assembly 30 and the terminal block 40. The rotating component 71 is located below the flat washer 80, and a stop seat 91 is provided above the flat washer 80. The control lever 50 is inserted into the stop seat 91. A spring 92 is installed at the stop seat 91, and the flat washer 80 has slots 81 distributed at equal intervals around its circumference. When the control lever 50 drives the stop seat 91 to rotate, the spring 92 rubs against the slots 81 at the flat washer 80, thus providing the effect of rotating the gear. When the control lever 50 is rotated, the control lever 50 drives the rotating component 71 and the stop seat 91 to rotate synchronously. When adjusting the walkie-talkie volume, the spring 92 simultaneously rubs against the slots 81 at the flat washer 80, thus producing the effect of adjusting the walkie-talkie volume.
[0022] The shaft sleeve 61 of the switch assembly mates with the switch component 62. The shaft sleeve 61 has a toggle finger 611, and the switch component 62 has a toggle groove 621 that mates with the toggle finger 611 of the shaft sleeve 61. The switch component 62 has a shaft hole 622, and a rotating shaft 63 is located in the shaft hole 622. The upper and lower ends of the rotating shaft 63 are respectively rotatably connected to the intermediate connecting seat 20 and the base 10. (See attached diagram) Figure 5As shown, the switch 62 is specifically fan-shaped. When the control lever 50 is rotated, the control lever 50 drives the shaft cylinder 61 to rotate. The finger part 611 of the shaft cylinder 61 inserts into and moves the slot 621 of the switch 62, thereby causing the switch 62 to deflect. When the switch 62 deflects, it can drive the contact piece in the base 10 to contact, thereby playing the role of controlling the walkie-talkie switch.
