Abstract

A removable-type hard disk drive bi-directional ingress and egress structure consisting of a connecting rod conjoined to the lower extent of a rotating shaft, with the other end conjoined to upper extent of another rotating shaft and thereby enabling opposite angles between the two upper and lower rotating shafts. When any single rotating shaft of the two upper and lower rotating shafts is selectively positioned by an extended handle, a tabular projection and two protruding catch hooks of a rotating shaft are utilized to coordinate the revolving of the rotating shafts by the handle such that the opposing action generated by the two upper and lower rotating shafts achieve a balanced ingress and egress effect at both the left and right sides. When the handle is pressed into closure, the catch hooks protrude due to the revolving of the rotating shafts and enables the drive housing to engage a replacement frame. When the handle is pulled open, since the rotating shafts and the connecting rod operate synchronously, the catch hooks are released from the check holes of the replacement frame, allowing flexible and efficient hard disk drive removal and installation under conditions of equalized force.

Claims

1. A removable-type hard disk drive bi-directional ingress and egress structure consisting of a handle situated at a front end of a hard disk drive, a rotating shaft disposed at one end of said handle, a tabular projection extending from periphery of said rotating shaft, a catch hook and a through-hole formed in said tabular projection, a connecting rod fastened via said through-hole to another rotating shaft at an opposite side of a drive housing, and said rotating shaft has disposed a catch hook;

when said handle is pressed into closure or pulled opened, said connecting rod revolves said rotating shafts which cause said catch hooks of said rotating shafts to protrude from or recede into said drive housing, thereby triggering engagement to or release from replacement frame check holes and enabling efficient and flexible hard disk drive ingress and egress into or from said replacement
