Abstract: A drawing case for an electronic information storage medium comprises a case body; a panel including a holder, a locking tool slot, a first through hole and a plurality of heat dissipation holes; a locking tool mounted in the locking tool slot and connected to an engaging piece that is provided with a first resilient element; a handle including a hook, one end of the handle being pivotally disposed on the holder, wherein the hook passes through the first through hole and engages with the engaging piece and is propped against the first resilient element. In this manner, the purpose of ease of drawing can be achieved by pressing the locking tool to open the handle, thereby not only significantly reducing manufacturing costs and assembly/disassembly complexity, such as eliminating the use of screws, but also enhancing the heat dissipation efficiency.

Abstract: An external hard disk drive case comprises a first housing, a trim ring, a second housing and a circuit board. The trim ring is made of a light-transmitting material and sandwiched between the first housing and the second housing. The circuit board is disposed within the first housing. The circuit board is provided thereon with a light-emitting component in the socket of which is disposed a light guiding strip that is peripherally disposed within the trim ring. When used, the light emitted by a luminous source of the light-emitting component disposed in the socket can lighten the light guiding strip peripherally disposed within the trim ring so as to produce a peripheral luminous effect which considerably improves the identifiable and aesthetic properties in use.

Abstract: A screw-tight plug for a sink has a plug body having a tube body with a drain hole and one end edge extending outwards to form an inclined flange. The drain hole of the plug body has an internal connector, and the connector has a threaded hole at a center portion and a plurality of drain gullies disposed around the opening of the threaded hole. A stop cock has a rounded disk-shaped cock head and a screw having a threaded portion, and the screw couples with the threaded hole of the connector. Based upon an engagement depth between the screw and the threaded hole, the cock head of the stop cock pushes against the flange to form a containment space, or the cock head separates from the flange to drain water.

Abstract: A light emitting module of a power supply includes a light guide plate disposed on a surface of a casing. A light emitting source such as a light emitting diode or a cathode fluorescent lamp is disposed surrounding the light guide plate. The light emitting source is electrically connected to a power supply module of the power supply. In addition, a decorating sheet is disposed at front of the light guide plate, and is provided with a light transmissive part in form of text or pattern. After being powered on, the power supply drives the light emitting source to emit light, and the light brightens the light guide plate via reflection, and emits from light transmissive part in form of text or pattern, so as to improve the decorative effect of the power supply.
