Background

Hard disk drives are the primary data storage devices for computers. The hard drive is used to store data, and most of the data required to operate the hardware and software of the computer is stored on the hard drive. The larger the capacity of the hard drive, the more data a computer can store. Thus, hard disk drives are the most important data storage devices for computers. If the hard disk drive is damaged, the computer will not function properly. The hard disk drive mainly includes a magnetic disk, a magnetic head, a motor, and a connection circuit, which are disposed in a housing. When a hard disk drive accesses data, the location of the data is first read and then the head is moved to a specified location on the disk to access the data. When data is stored on a hard disk drive, the available storage locations are first found and then the head is moved to the specified location of the disk to store the data. Hard disk drives are typically mounted in a hard disk drive tray. The hard disk drive tray includes a tray body and a handle mounted to the tray body and facilitating removal of the hard disk drive tray from the chassis by a user. Since the hard disk drive tray is subjected to large accelerations during operation of the hard disk drive, it is necessary to lock the hard disk drive tray to the chassis to prevent the hard disk drive tray from unintentionally slipping off the chassis.

Chinese patent with publication No. CN108710419A now discloses a pull-out hard disk tray mechanism, which includes: the hard disk box comprises a hard disk box guide rail, a hard disk box assembly and an elastic buckle assembly, wherein a limiting hole is formed in one side above the hard disk box guide rail, and the elastic buckle assembly is arranged on a hard disk box of the hard disk box assembly in a position corresponding to the limiting hole; the elastic buckle assembly comprises: handle, handle shell fragment, hard disk box apron, reset spring, pin, the handle is located on the hard disk box, the handle middle part is equipped with first through-hole, the handle shell fragment runs through first through-hole setting, handle shell fragment and reset spring pass through the pin is fixed in on the hard disk box apron, hard disk box apron is fixed in on the hard disk box, the handle shell fragment is including pressing splenium and buckling parts, the splenium of pressing of handle shell fragment one end with the portion of gripping of handle corresponds the setting, the buckling parts of the handle shell fragment other end with spacing hole looks lock.

By adopting the scheme, when workers install the hard disk box, the workers push the handle, the handle drives the hard disk box to advance to the case, and the hard disk box slides into the case through the hard disk box guide rail. However, after the hard disk cartridge is inserted into the chassis, the hard disk cartridge may be pulled out due to the accidental touch of the handle, and there is a need for improvement.
