[0020] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the drawings to facilitate understanding by those skilled in the art.
[0021] The utility model discloses a strong mechanical feeling sound box table lamp adjusting knob. The strong mechanical feeling sound box table lamp adjusting knob mainly comprises a support base 1, an adjusting wheel 2, a spring 3, a limiting bead 4, and a circuit board 5. The support base 1 is installed in a sound box housing 11. The adjusting wheel 2 is rotatably installed on the support base 1 and the circuit board 5 through a short shaft 8. Installation holes 22 are uniformly arranged along the circumference on the end face of the adjusting wheel 2. The limiting bead 4 is installed in the installation hole 22 by compressing the spring 3. Spherical grooves 12 matching the limiting beads 4 are uniformly arranged on the support base 1. The adjusting wheel 2 is limited by the engagement of the limiting beads 4 and the spherical grooves 12. The adjusting wheel 2 is electrically connected to the circuit board 5. During the adjustment process, the retractable limiting beads 4 in the adjusting wheel 2 are engaged with the spherical grooves 12 on the support base 1, so that the adjustment process has a sense of pause and a clicking mechanical feeling, enhancing the sensory experience of the operator. When the rotation stops, the spherical head structure at the top of the limiting bead 4 stays in the corresponding spherical groove 12, immediately stopping the rotation of the adjusting wheel 2 and ensuring the accuracy of volume adjustment.
[0022] A momentary switch 6 is installed on the circuit board 5, and the momentary switch 6 is located inside the adjusting wheel 2. The top end of the short shaft 8 of the adjusting wheel 2 is connected to the circuit board 5 through an end cap 7. The short shaft 8 has a clearance fit with both the end cap 7 and the support base 1. A compression spring 81 is arranged inside the short shaft 8, and ball bearings 82 with the compression spring 81 are installed at both ends of the short shaft 8. Spherical grooves 9 matching the ball bearings 82 are arranged on the inner end face of the end cap 7 and in the installation holes of the support base 1. The short shaft 8 has a clearance fit with both the end cap 7 and the support base 1, enabling the adjusting wheel 2 to have a radial displacement. The ball bearings 82 supported by the compression spring 81 are positioned coaxially with the spherical grooves 9, applying a radial force to the adjusting wheel 2. Overcoming the elastic force of the compression spring 81, the ball bearings 82 disengage from the spherical grooves 9, forming a radial movement, thereby triggering the momentary switch 6 and entering the adjustment mode. Then, the adjusting function is realized by rotating the adjusting wheel 2 left and right.
[0023] The top of the adjusting wheel 2 is rotatably connected to the circuit board 5 through a short shaft, supporting and installing both sides of the adjusting wheel 2, avoiding the adjusting wheel 2 being subjected to a deflection force during rotation, ensuring the smooth rotation of the adjusting wheel 2, guaranteeing the connection accuracy, and being beneficial to extending the service life of the adjusting wheel 2.
[0024] Both ends of the support base 1 are connected to the circuit board 5 through support columns 13 and screws, ensuring the relative fixation of the support base 1 and the circuit board 5 and improving the stability of the circuit board 5.
[0025] The adjusting wheel 2 is provided with anti-slip knurling for convenient adjustment.
[0026] The sound box housing 11 is provided with a through hole, and one side of the adjusting wheel 2 extends out through the through hole for easy adjustment.
[0027] Working process:
[0028] The short axis 8 has a clearance fit with both the end cover 7 and the support base 1, enabling the adjusting knob 2 to have radial displacement. The ball 82 supported by the compression spring 81 is positioned coaxially with the spherical groove 9, applying a radial force to the adjusting knob 2. Overcoming the elastic force of the compression spring 81, the ball 82 disengages from the spherical groove 9, forming a radial movement, thereby triggering the momentary switch 6 and entering the adjustment mode. Then, rotating the adjusting knob 2 left and right realizes the adjustment function. The adjustment is carried out by directly turning the adjusting knob 2 by hand. The retractable limit bead 4 inside the adjusting knob 2 is engaged with the spherical groove 12 on the support base 1, making the adjustment process have a sense of pause and a mechanical feeling of clicking, enhancing the operator's sensory experience. When the rotation stops, the ball head structure at the top of the limit bead 4 stays in the corresponding spherical groove 12, immediately stopping the rotation of the adjusting knob and ensuring the accuracy of the volume adjustment, thereby realizing the precise adjustment of the volume.
[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
