  • Device for fixing hard disk
    Patent number: 11347281
    Abstract: A device for fixing a hard disk is provided, which is arranged in a case and can install multiple hard disks at one time. The device for fixing a hard disk includes fixing brackets and an elastic support member. The elastic support member is arranged between two adjacent fixing brackets. The number of the fixing bracket is even, and the fixing brackets are arranged in symmetry. The hard disk is placed between the elastic support member and one single fixing bracket, which can quickly and conveniently realize the fixing and installation of the hard disk, save a lot of space, and can be arranged in array in the case. The device has high reliability and good shock absorption effects. When the space of the case is limited, the demand of high-density storage configuration can also be achieved.
