Abstract: The present invention discloses a basin faucet quick-mounting base device, including a base body, an adapting connector, a connecting screw, a sealing gasket, and a locking member, where the base body is provided with a central through hole and a screw mounting hole, the sealing gasket is disposed on a bottom surface of the base body to be in sealing contact with a top surface of a mounting table, and the connecting screw is disposed in the screw mounting hole and then tensions the locking member to fix the base body to the mounting table; an inner side wall of the central through hole is provided with a spline groove, a column surface of the base body is provided with a set threaded hole.

Abstract: The present utility model belongs to the technical field of charging cases, and discloses a light guide structure of an earphone charging case, including a charging case and earphones. A shell of the charging case is provided with a shell light guide element, and the element penetrates the shell. The earphone is provided with a light source. When the earphone is placed in the charging case, light generated by the earphone light source can be transmitted to the shell light guide element, making the guide element emits light. The light guide structure of the earphone charging case use the light source of the earphone directly through optical simulation so as to realize secondary light guide, so that the shell of the charging case emits light, no additional light source is required, costs are reduced, the size of charging case can be effectively reduced, and miniaturization and lightweight can be realized.
