Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In one embodiment, please refer to fig. 1 and 2, a suspended type screen pasting knob, including base 10, fixedly connected with PCBA9 on the base 10 is equipped with conductive rubber 8 on the PCBA9, and conductive rubber 8 installs and plays waterproof dirt-proof effect on PCBA9, and conductive rubber 8 cooperates with the golden finger on the PCBA9 simultaneously, produces the effect that the button pressed, the shell 7 is dismantled to the top of base 10, base 10 installs with shell 7, realizes the closure and the protection of switch, and PCBA9 installs on base 10, and other parts are assembled from the bottom upwards in proper order and are fixed, and base 10 plays overall supporting role, and shell 7 is the overall skeleton of switch, and the top rotation of shell 7 is connected with inner shell 3, and the top of inner shell 3 is equipped with knob 2, in inner shell 3 connection knob 2 inside groove, be equipped with button 1 on the knob 2, button 1 installs on knob 2, presses the function such as confirm.

In one case of the present embodiment, a bearing 4, a spring piece 5 and a rail body 6 are provided between the inner housing 3 and the outer housing 7. The knob 2 is sleeved outside the inner shell 3 of the knob 2, forms 360-degree stepless rotation together with the bearing 4 and the spring piece 5, and generates obvious gear feeling of the knob 2, clear and not harsh hearing feeling, and the track body 6 is assembled in the bearing 4 to realize up-and-down pressing movement of the button 1.

In one case of this embodiment, the track body 6 is fixed in the housing 7, and the track body 6 is provided with continuous and uniform blocking pieces, and the combination of the track body 6 and the photoelectric sensor on the PCBA9 can detect the rotation angle and the rotation pulse number of the knob 2, and can adjust the volume and the wind speed or select the multimedia audio source and the video source.
