When in use, vertically put the slide rail guide column of the hard disk fixing bracket into the slide rail guide groove of the base, then push the fixing bracket forward horizontally, and the hard disk is connected with the hard disk connector.

In order to facilitate disassembly, the hard disk fixing frame is provided with a stainless steel handle, the two ends of the handle are fixed on the side positions of the fixing frame, and a bayonet is provided at the front end of the handle; a spring buckle is provided at a corresponding position of the base 12 .

When the fixing frame with the hard disk is installed on the base, the handle is pressed to a horizontal position, at this time, the spring buckle is fastened to the bayonet of the handle to prevent the handle from rebounding, and at the same time, the hard disk is completely connected to the connector on the base.

Two hard disk screw fixing holes are respectively arranged at the relative positions on the left and right sides of the hard disk fixing frame. The positions of the screw fixing holes are equivalent to the screw fixing positions of a 3.5-inch hard disk. It is equivalent to the position of the fixing screw of the 2.5-inch hard disk.

The hard drive bracket is compatible with 3.5-inch and 2.5-inch hard drives. When in use, the hard drive can be locked on the hard drive bracket with 4 screws. The side of the 3.5-inch hard drive has 4 screws, and the bottom of the 2.5-inch hard drive has 4 screws.

The beneficial effects of the utility model are as follows: the application is applied to the hard disk hot swapping of Smart rack custom nodes, and the hard disk bracket structure of the utility model can realize fast replacement of the hard disk without plugging and unplugging cables, save maintenance time, and improve the overall performance. Cabinet O&M efficiency.

Detailed ways

Below with reference to shown in accompanying drawing, the utility model is further described by specific embodiment:

As shown in the figure, a node tray for hot-swappable hard disks, the node includes two trays, one is the inner tray 1, the other is the outer tray 2, the inner tray 1 is fixed on the outer tray 2 through slide rails, One end of the power cord 3 is connected to the wiring board of the inner tray 1 through the Z-shaped retractable cable rack 4 arranged on the outer tray 2, and the other end is connected to the terminal of the outer tray 2, and the hard disk 5 is fixed to the inner tray through the bracket 1 on.

When it is necessary to unplug the hard disk, pull out the inner tray, and at this time the cable is stretched with the retractable Z-shaped bracket, so as to ensure that the system is not powered on when the hard disk is removed, and the hard disk hot-swappable function is realized.

The hard disk 5 is fixed on the inner tray 1 through a bracket, and the bracket includes a base 12 and a hard disk fixing frame 13 , wherein the base is fixed on the inner tray 1 , and the hard disk 5 is installed on the base 12 through the fixing bracket 13 .

The base 12 is a box-shaped structure with an open rear end, wherein a hard disk connector 9 is arranged at the front end, an L-shaped slide rail guide groove 10 is arranged on the side, and a slide rail guide post 8 is arranged at a corresponding position on the side of the hard disk fixing frame 13 .
