The fixed structure of the hard disk module

technical field

The present invention relates to a fixing structure, and in particular to a fixing structure of a hard disk module.

Background technique

With the advancement of technology, computers have become an indispensable tool in our daily life. Generally speaking, there are many main components in a computer, such as optical drive, magnetic disk drive, hard disk drive, etc. Among them, the hard disk provides low-cost, high-speed and large-capacity storage space, which can be used as storage for operating systems, applications, and User data, etc., so most of the software and data required for computer use are stored in the hard disk, which can be said to be the most important data storage component of the computer.

Generally, hard disks are mostly installed inside the computer. In order to firmly install the hard disk in the computer, first the hard disk needs to be fixed in the frame of a host computer, and the side of the frame has multiple screw holes. Correspondingly, so that the frame and the hard disk can be locked and combined by screws. At present, hard disks need to rely on a large number of screws for locking assembly and disassembly. Not only is the assembly labor-intensive, but the production speed is also slow, which virtually increases the production cost of hard disks.

In addition, if too much force is applied when the screws lock the hard disk and the mainframe frame, it is easy to cause the screw teeth to disintegrate, causing the screws to spin idly and the screws cannot be locked. In addition, a screwdriver must be used when repairing, replacing or expanding the hard disk. The tool turns loose a large number of screws to get the job done. Therefore, the method of locking the hard disk with screws will not only cause inconvenience in assembly and operation, but also cause a lot of time and manpower to be spent on disassembly and installation. In other words, this method of screw-locking the hard disk is not suitable for the current trend of tool-less disassembly of the whole machine.
