Description

Technical Field

[0001] The utility model relates to the field of hard disk rack technology, in particular to a hard disk rack and a chassis. Background Art

[0002] A hard disk rack is usually used in a computer case for installing a hard disk. Technical personnel in the industry have been studying how to make the hard disk rack more convenient to install.

[0003] For example, CN 210377330 discloses a computer hard disk rack for convenient installation of hard disks, including two mounting plates, the mounting plates are slidably connected to a placement plate via a slide rail fixed thereon, the placement plate is provided with a placement groove, a pressure plate is rotatably connected to the groove wall of the placement groove via a rotating shaft, a hook is fixedly connected to the pressure plate, a corresponding card column is fixedly connected to the placement plate, a plurality of "L"-shaped card rods are provided on one side of the lower side of the placement plate, and a plurality of corresponding through grooves are provided on the slide rail.

[0004] When in use, first install the two mounting plates inside the chassis respectively by bolts, then put the hard disk into the placement slot, then rotate the pressure plate to make its hook and the column engage with each other, then press the connecting rod, and then align the slide slot and the slide rail with each other, and then push the placement plate. When the inner end of the placement plate is aligned with the inner end of the slide rail (the end of the placement plate and the slide rail with a shorter length close to the mounting plate is the inner end), the connecting rod can be released. At this time, the card rod is pushed toward the outside of the inner cavity under the action of the elastic member, and then the placement plate is continued to be pushed until the placement plate cannot be pushed anymore (when the card rod moves to the top of the through-slot, it will bounce to the bottom of the through-slot under the action of the elastic member. At this time, the card rod continues to move until the card rod contacts the inner end slot wall of the through-slot, and the card block is engaged with the bayonet), and the installation of the placement plate is completed.

[0005] The mounting plate and placement plate need to be molded by injection molding. In order to ensure the structural strength, they must be designed to be of sufficient thickness. The heat dissipation is not ideal, and the connection between the card block and the card port is formed by the setting of the connecting rod, so the structure is relatively complicated.
