Abstract

The invention provides a knob structure. The knob structure comprises a knob cap, a hoop and a rotating shaft, wherein an accommodating slot is formed in the knob cap; a limiting slot is formed in the bottom of the accommodating slot; a notch is formed in the side wall of the limiting slot; the outer side of the limiting slot is sleeved with the hoop; the hoop comprises an annular body and an elastic arm; the elastic arm is arranged towards the interior of the body; the elastic arm is accommodated in the notch, and is arranged as a magnetizer; one end of the rotating shaft is accommodated in the limiting slot; a clamping slot is formed in the side wall of the rotating shaft; a free end of at least one elastic arm penetrates through the notch and enters the clamping slot; the elastic arm elastically deforms under the effect of a magnetic field so as to enter and exit from the clamping slot, so that the hoop and the rotating shaft can be detachably connected with each other; the rotating shaft is connected with the knob cap through the elastic arm; the rotating shaft is tightly clamped by the elastic arm and cannot move outwards, so that the knob cap is stably connected with the rotating shaft. The knob structure can effectively promote the plugging and inserting effect of the rotating shaft. The service life of the knob structure is prolonged.

Description

technical field [0001] The invention relates to accessories of electronic equipment, in particular to a knob structure. Background technique [0002] The knob is a manual control element connected with the switch to control the opening or opening degree of the switch. Its edge is generally engraved with one or a series of labels, most of which are circular convex structures, discs, etc., so that it can realize Rotary control of the knob. At present, most traditional knobs include a knob base, a knob cap, and a connecting shaft, and the knob cover is connected to the knob base through the connecting shaft. Usually, the connecting shaft is provided with an external thread, and the knob cap and the connecting shaft are threaded. After being used for a period of time, slipping is likely to occur between the knob cap and the connecting shaft, so that the knob cap is separated from the connecting shaft, which affects the use of the knob. Contents of the invention [0003] The...
