Abstract: A computer casing structure is composed of a chassis, which is provided with a front panel on which is mounted with a lower long through-hole and an upper long through-hole; a metallic shield, which is punched with a plurality of through-holes and is locked and positioned into the lower long through-hole; a CD-ROM module, which is positioned at a rear side of the upper long through-hole; and a main board, a front edge of which is provided with a plurality of I/O connection ports, and which is fixed in the chassis, with the I/O connection ports being corresponding to the through-holes of the metallic shield. By mounting the CD-ROM module, a hard disk drive module, and I/O connectors on the same front panel and installing a data transmission port on a rear panel, convenience in operation is developed, and an effect of ventilation and heat dissipation is improved.

Abstract: A control apparatus for carrying a heavy object is composed of a base which is connected with an elastic assembly that can move upward and downward, and the elastic assembly which is provided with an upper plate for loading the heavy object. By an upward displacement of the elastic assembly, the upper plate can push up the heavy object, and by a downward displacement of the elastic assembly, the upper plate of the elastic assembly can be escaped from the heavy object, and the heavy object can be escaped from the elastic assembly and the base, such that during a process of moving or transporting the heavy object, the heavy object can be quickly, conveniently, and safely escaped from or slid into the base, and in the mean time, a displacement of a weight-lifting vehicle or a crane can be eliminated upon being loaded with the heavy object.

Abstract: A screwing control device of a computer chassis is composed of a computer chassis, a panel of which is pre-built with a plurality of positioning holes; a screw element, a center of which is provided with a screw hole and which is able to be locked and fixed into one of the positioning holes; and a bolt, which is transfixed into a through-hole of a board element, and is then screwed into the screw hole of the screw element. Therefore, a quantity of the screw elements which are actually used for screwing can be effectively controlled, and pre-built projected bolts which are not necessarily used for screwing can be eliminated.
