Embodiment 1

[0036] like figure 1 , figure 2 , Figure 5 Shown is one of the embodiments of the present invention, in this embodiment, an anti-false trigger adjustment knob mechanism is installed on the housing 9 of the product to be regulated, and the product to be regulated can be a HiFi player, walkie-talkie, miniature radio And other products, other components are installed in the casing 9, for example, the PCB board 2 is arranged in the casing 9, and the screen 1 is covered on the casing 9.

[0037] like figure 2 As shown, the anti-false trigger adjustment knob mechanism includes an adjustment knob 3, the adjustment knob 3 is located outside the housing 9, the driving gear shaft 4 is installed on the adjustment knob 3, and the housing 9 is provided with a through hole 9-1 to form a slideway. The hole 9-1 is an oblate long and narrow hole, and the driving gear shaft 4 extends into the inside of the housing 9 from the through hole 9-1 and can slide in the through hole 9-1; the insi...

Embodiment 2

[0049] In this embodiment, the difference from Embodiment 1 is that the elastic reset mechanism can reset the drive gear shaft 4 by pulling, and in the natural state, the elastic reset mechanism pulls the drive gear shaft 4 to the position of the through hole 9-1. At the far end, a reverse thrust is applied to the adjustment knob 3, and the drive gear shaft 4 is pushed to the proximal end of the through hole 9-1 against the pulling force of the elastic reset mechanism, and the adjustment knob 3 is rotated to adjust the potentiometer 6.

[0050] Correspondingly, the elastic return mechanism includes a tension spring, no slide block is required, and the tension spring is always in a tensioned state. Extension spring one end can be provided with draw ring, wears on the driving gear shaft 4, does not affect the rotation of driving gear shaft 4, and the extension spring other end also arranges draw ring, is connected and fixed on the supporting platform 9-5 and gets final product. ...

Embodiment 3

[0053] In this embodiment, an audio player includes a housing 9 on which the anti-false trigger adjustment knob mechanism described in Embodiment 1 or Embodiment 2 is installed, and the housing 9 is provided with a through hole 9 -1, the adjustment knob 3 is installed at the through hole 9-1, push the adjustment knob 3 to the near end of the through hole 9-1 to adjust the volume, when no pushing force is applied, the adjustment knob 3 moves to the far end of the through hole 9-1 by itself , at this time, the rotary adjustment knob 3 is in an idling state, and the volume cannot be adjusted.

Abstract

The invention discloses an anti-false-triggering adjustment knob mechanism and a sound equipment player, for solving the technical problem of unstable volume caused by proneness to false triggering of an adjustment knob in the application process of a sound equipment player. The mechanism is installed on a housing of an adjusted product and comprises an adjustment knob, the adjustment knob is provided with an driving gear shaft, the housing is provided with a through hole to form a chute, the driving gear shaft extends into the housing from the through hole and can slide in the through hole; and the housing is internally provided with a potentiometer, the potentiometer is provided with a driven gear shaft, and the driving gear shaft is engaged with the driven gear shaft when sliding to a near end in the through hole and is disengaged from the driven gear shaft when sliding to a far end. When the two gear shafts are engaged, size adjustment of parameters to be changed is realized, and the adjustment knob runs idly when the two gear shafts are separated, such that false triggering of the adjustment knob is avoided.

Description

technical field [0001] The invention relates to an adjustment knob mechanism on an electronic product, in particular to an anti-mis-trigger adjustment knob mechanism. The invention also relates to an audio player. Background technique [0002] The volume adjustment knob is widely used in electronic products, such as HiFi players, walkie-talkies, etc. When the user puts the product in his pocket, the existing volume adjustment knob is easily triggered by mistake, causing the volume to suddenly increase or decrease, which affects the consumer's experience with the product. [0003] The prior art also has an anti-mis-touch knob design. For example, a Chinese utility model patent "A Control Knob with Locking Function" (CN203414876U) discloses an anti-mis-touch knob, which is used on the control box of the production line. Specifically, it includes a knob seat 1 fixedly arranged on the control box, a knob 2 is arranged on the knob seat 1 for rotation, a locking mechanism for lo...
