Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract

Disclosed is a rotary knob structure (10). The rotary knob structure (10) comprises a rotary knob cap (11), a hoop (12) and a spindle (13). The rotary knob cap (11) is provided with a containing groove (111). A limiting groove (112) is provided at the bottom of the containing groove (111). A side wall of the limiting groove (112) is provided with a notch (113). The hoop (12) is sheathed on an outer side of the limiting groove (112). The hoop (12) comprises an annular body (121) and an elastic arm (122). The elastic arm (122) is provided facing the interior of the body (121). The elastic arm (122) is housed in the notch (113). The elastic arm (122) is a magnetically conductive body. An end of the spindle (13) is housed in the limiting groove (112). A side wall of the spindle (13) is provided with a clamping groove (132). At least one free end of the elastic arm (122) passes through the notch (113) and enters the clamping groove (132). The elastic arm (122) undergoes elastic deformation under the action of a magnetic field, so that the elastic arm (122) passes in and out of the clamping groove (132), thereby enabling the hoop (12) to be connected to the spindle (13) in a detachable manner.The spindle (13) is connected to the rotary knob cap (11) via the elastic arm (122), so that the elastic arm (122) clamps the spindle (13) tightly and the spindle (13) cannot move outwards, whereby the rotary knob cap (11) and the spindle (13) are connected stably. The rotary knob structure (10) effectively improves the insertion and extraction effects of the spindle (13), prolonging the service life of the rotary knob structure (10).

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...
