Combined turn knob

Abstract

A combined knob comprises a knob base, an annular groove is formed on the upper surface of the knob base, a transparent cover body is arranged on the knob base which is surrounded by the annular groove, the upper surface of the transparent cover body is an outer convex arc surface, the side surface of the transparent cover is extended to the outside to form a flange, thereby forming an outer step, a connecting ring is simultaneously arranged in the annular groove, an inner step which is buckled with the outer step is arranged on the connecting ring, and the connecting ring is connected with the knob base, thereby positioning the transparent cover body on the knob base. By adopting the above-mentioned structure, the combined knob can not only have beautiful visual style, but also be applicable to different devices by setting different patterns and textures; furthermore, as the transparent cover body is positioned in the middle part of the knob base, the patterns or the textures can occupy a larger proportion and be more complete, the combined knob simultaneously utilizes the role as a convex lens of the outer convex arc surface of the transparent cover body to lead the patterns or the textures to take on an amplification effect visually, and create an image of a crystal magic cube, thereby providing people with combined knobs with a greater variety.
