## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a positioning structure of an electrical peripheral device and, in particular, to a positioning structure of an electrical peripheral device for securing an electrical peripheral device such as a power supply and a hard disk drive.
Description of Related Art
With substantial development of the computer technology, the design, manufacturing, and assembly of computer equipment advance accordingly. To allow the vendor or user to change, repair, or upgrade the electrical peripheral device such as the power supply and hard disk drive by themselves, the electrical peripheral device is usually fixed to the supporting frame of the computer equipment using screws. Thus, the vendor or user can quickly install/uninstall the electrical peripheral device in/from the supporting frame.
A traditional method of positioning the electrical peripheral device to the supporting frame by screws is as follows. Firstly, the vendor or user prepares some screws and appropriate hand tools; the screws are then placed, one by one, through the respective holes formed on the electrical peripheral device and the supporting frame, and then the hand tools are used to drive the screws. Thus, the screws and the holes are combined firmly and the electrical peripheral device is positioned to the supporting frame well.
However, the above method has the following disadvantages. First, the hand tools are required for the installation/uninstallation of the electrical peripheral device to attach/detach the screws one by one. Therefore, the additional requirement of appropriate tools and the tedious process are inconvenient for the vendor or user and retard the processes of installation and uninstallation. Second, after the screws are detached, a single screw is not easy to keep and easy to miss due to its small volume, failing to continue the following installation process.
In view of foregoing, the inventor pays special attention to research with the application of related theory and tries to overcome the above disadvantages regarding the above related art, which becomes the goal of the inventor's improvement.
SUMMARY OF THE INVENTION
The present invention is to provide a positioning structure of an electrical peripheral device, which rotates a rotating piece to control a detent part to lock or be detached from a positioning plate correspondingly. Thus, the installation and uninstallation of the electrical peripheral device are made efficient and the convenience of using the positioning structure is improved.
The present invention provides a positioning structure of an electrical peripheral device having a positioning plate. The positioning structure comprises:
a fastening seat having an engaging portion; and
a rotating piece pivoted around and rotating with respect to the fastening seat. The rotating piece has a latching portion and a detent part at one end thereof. When the latching portion is latched to the engaging portion, the detent part presses and locks the top of the position plate correspondingly.
The present invention has the following effects.
First, the detent part can press and lock the top of the positioning plate, preventing the electrical peripheral device from swaying up and down. Thus, the electrical peripheral device can be fixed more firmly to the positioning structure.
Second, when the rotating piece is rotated, it can bring the detent part to press and lock or be detached from the positioning plate correspondingly. The quick installation/uninstallation of the electrical peripheral device in/from the positioning structure is thus achieved. The assembly and disassembly of the vendor or user are made more efficient.
Third, during the processes of installing/uninstalling the electrical peripheral device in/from the positioning structure, no auxiliary tools and disassembly devices are required. Thus, there are no issues of tedious installation/uninstallation processes and screws lost easily, providing improved convenience of using the positioning structure for the vendor or user.
Fourth, when the latching portion is latched to the engaging portion, the rotating piece and the fastening seat can be positioned to each other such that the rotating piece is locked by the latching portion and the engaging portion and thus cannot move, which forces the detent part to keep pressing and locking the positioning plate and prevents the positioning plate from being detached from the detent part when swayed or impacted, such that the electrical peripheral device is fixed firmly to the positioning structure.
