A VOLUME KNOB COMBINATION STRUCTURE OF CAR AUDIO

摘要

The present invention is to easily assemble the volume knob 110 on the rotary shaft 122 to the volume switch 120 of the car audio, while preventing the coupling force is weakened.;The present invention is formed on the back of the volume knob 110, the press groove 114 having a predetermined length is formed and the boss 112 formed a plurality of engaging holes 116 outward from the press groove (114), Semi-circular shaft hole 132 having a locking jaw 134 is formed on the outer circumferential surface and a plurality of locking projections 136 inserted into the pressing groove 114 of the boss 112 and inserted into the locking holes 116 are formed on the outer circumferential surface. The shaft holder 130 and the protrusion 126 fitted to the shaft hole 132 of the shaft holder 130 and caught by the locking jaw 134 are formed at the front end thereof to the rotary shaft 122 of the volume switch 120. It is composed of a press-fit portion 124 formed.;The present invention facilitates the coupling work of the volume knob 110 and when the volume knob 110 is damaged or the press-fit groove 114 of the boss 112 is loosened, the volume knob 110 can be easily used by replacing the volume knob 110. The assembly workability of the car audio and the replacement workability of the parts is improved.
