(a) Field of the Invention
The present invention relates to a bi-directional side emplacing computer casing, and more particularly to a computer casing wherein its two sides can be both used for emplacing expansion equipment such as a floppy disk drive, a CD-ROM disk drive, or a burner, so as to be in compliance with a requirement of an operator.
(b) Description of the Prior Art
As a popularity of computer technology, almost every house is provided now with a personal computer for use, and the ordinary personal computer is composed of a computer host and a monitor, wherein the computer host is provided with all kinds of electronic parts which are installed in a computer casing. The most primary object of computer casing is to protect the interior electronic parts from being interfered by ambient conditions, and is also to protect ambient objects from being damaged by a radiation or an electromagnetic wave of the electronic parts. Referring to
Accordingly, in lieu of the shortcomings in using the ordinary computer casing, a brand new bi-directional side emplacing computer casing is invented, wherein openings at two faces of an expansion rack are exposed at two sides of a cage respectively, plural sets of symmetric sliding grooves are installed between side walls along the openings at two sides of the expansion rack respectively, and roller screws which are corresponding to the aforementioned sliding slots are installed on expansion equipment such as a floppy disk drive, a CD-ROM disk drive, or a burner, such that the aforementioned expansion equipment can be emplaced at the other side of present invention according to a requirement of an user. On the other hand, side boards which are provided with openings corresponding to the expansion equipment can be used both with their two sides and therefore can be used to quickly change directions and positions for emplacing the expansion equipment into the computer casing.
The primary object of present invention is to provide a computer casing, two sides of which can be both used for emplacing expansion equipment, thereby quickly changing directions and positions for emplacing the expansion equipment into the computer casing, to be in compliance with a requirement of an operator.
Another object of the present invention is to provide a computer casing which is convenient to be disassembled and can facilitate an expansion of all kinds of equipment, thereby reducing a possibility of collision between interior electronic parts.
Accordingly, the bi-directional side emplacing computer casing of present invention comprises primarily a cage, two side boards, as well as an expansion rack, a motherboard rack, and a hard disk rack inside the cage, wherein the expansion rack is installed at a position close to a front face of the cage with its openings facing toward a left side and a right side to the cage respectively, and its two side walls are provided with plural sets of symmetric sliding grooves extended inward from the openings at two sides. The symmetric sliding grooves are not interconnected, so as to provide for a sliding and an insertion of expansion equipment which is installed with roller screws. In addition, the two side boards are provided with an expansion hole corresponding to the expansion rack respectively, and fixing holes at peripheries of the side boards can be used both with two sides. Furthermore, the motherboard rack is sliding and inserted into the sliding slot at a bottom face of the cage from a lower part of rear face of the cage, the hard disk rack is emplaced from an opening at a top part of rear face of the cage, and back panels of the aforementioned motherboard rack and the hard disk rack are all directly screwed at the rear face of the cage.
Accordingly, when using the aforementioned structures, the expansion equipment such as the floppy disk drive, the CD-ROM disk drive, or the burner is selectively installed at one side of the computer casing according to the requirement of operator, and the roller screws of aforementioned expansion equipment are sliding and inserted into the sliding slot at a proper side of the expansion rack, next a signal line of expansion equipment is connected with the motherboard, so as to be connected with a power cord extended from a power supply, finally the two side boards are sealed at the left and right sides of the cage, respectively, and the corresponding expansion hole on the side board is opened to expose a front panel of the disk drive. Moreover, the motherboard rack and the hard disk drive are installed respectively at proper positions at an upper and a lower parts of the rear face of the cage, without being interfered with each other upon disassembling. Therefore, the computer casing of present invention is convenient to be disassembled, and can facilitate an expansion of all kinds of equipment, thereby reducing a possibility of collision between the interior electronic parts.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
Referring to
The cage 10 is a rectangular body constituted by a plurality of frameworks 11, a front position of which is provided with a front panel 12, a rear position of which is provided with a back panel 13, and an upper and a lower parts of which are provided with a top board 14 and a bottom board 15 respectively, thereby forming a body with two hollow sides. In addition, peripheries at two sides of the cage 10 are provided with a plurality of positioning holes 16 and screw holes 17 for positioning the side boards 20, an upper part of the back panel 13 is provided with an opening 13a for emplacing the hard disk rack 50, a lower part of the back panel 13 is provided with an opening 13b for emplacing the motherboard rack 40, and proper positions at two sides of the bottom board 15 are installed with sliding slots 15a.
The two side boards 20 are made into a size and a shape corresponding to the hollow faces at two sides of the cage 10, and the side boards 20 are all provided with expansion holes 21 corresponding to the expansion rack 30. Peripheries of the side boards 20 are all installed with fixing holes 22 corresponding to the screw holes 17 on the cage 10. Furthermore, one of the side boards 20 is provided with an emplacement hole 23 for installing a fan for dissipating heat.
The expansion rack 30 is installed at a position close to a front face of the cage 10, and its openings are facing toward a left side and a right side to the cage 10, respectively. In addition, its two side walls are provided with plural sets of symmetric sliding grooves 31 extended inward from the openings at two sides, and the symmetric sliding grooves 31 are not interconnected, so as to provide for a sliding and an insertion of expansion equipment 2 which is provided with roller screws 2a.
The motherboard rack 40 is composed of a back panel 41 and a lower sliding board 42, which is roughly in an L-shape upon being viewed from a side. Peripheries of the back panel 41 are provided with a plurality of fixing holes 41a, a proper position at a center of the back panel 41 is provided with an opening 41a for transfixing a motherboard and connection ports of interface cards, and two sides of the lower sliding board 42 are provided with proper sliding pieces 42a which can be sliding and inserted into the sliding slots 15a at the bottom face of cage 10.
