A securing mechanism includes a rail unit and a locking unit. The rail unit has a first rail structure, a guiding surface that is formed with a pin extension slot, and a first engaging structure. The locking unit has a fixing pin protruding into the pin extension slot, a second rail structure cooperating with the first rail structure to move the locking unit between an unlocked position, where the fixing pin is away from a fixing hole of the electronic device and where the first engaging structure is separated from the second engaging structure, and a locked position, where the fixing pin engages the fixing hole of the electronic device and where the second engaging structure engages the first engaging structure for fixing the electronic device to a mounting frame. |

1. A securing mechanism adapted for fixing at least one electronic device to amounting frame, the mounting frame defining an accommodating space, and having a lateral plate and an opening that communicates the accommodating space, the electronic device being able to be inserted into or pulled out from the accommodating space through the opening in an insertion direction that is parallel to the lateral plate, and being formed with at least one fixing hole that faces the lateral plate, said securing mechanism comprising:
at least one rail unit having
a first rail structure that is adapted to be fixed on the lateral plate,a guiding surface that is adapted to be formed at an outer end of the lateral plate, that has a flat surface portion and an inclined surface portion arranged in the insertion direction, and that is formed with at least one pin extension slot extending substantially in the insertion direction, said flat surface portion being parallel to the lateral plate, said inclined surface portion extending from said flat surface portion toward the opening and being inclined outwardly from the lateral plate,a through hole that extends through the lateral plate to communicate the accommodating space, and that is farther from the opening than said guiding surface, anda first engaging structure that is adapted to be fixed on the lateral plate; and at least one locking unit mounted to said rail unit, and having
a main body that has a main portion and a deformable portion arranged in the insertion direction, and at least one fixing pin protruding from said deformable portion into said pin extension slot, said deformable portion extending from said main portion toward the opening and abutting against said guiding surface,a second rail structure that is fixed on said main body and that cooperates with said first rail structure such that said locking unit is slidable in the insertion direction between an unlocked position which is proximate to the opening, and a locked position which is distal from the opening,a first flexible portion that extends from said main body toward the opening, that is bent into the accommodating space, that is elastically deformable relative to said main body, and that has a first slope facing away from the opening, anda second flexible portion that extends from said main body, that is elastically deformable relative to said main body, and that has a second engaging structure being engageable removably said first engaging structure; wherein, when said locking unit is at the unlocked position, said first flexible portion extends into the accommodating space through said through hole, said deformable portion deforms to move said fixing pin away from the accommodating space, and said first engaging structure and said second engaging structure are separated from each other; and wherein, when the electronic device is inserted into the accommodating space, said first flexible portion is pushed by the electronic device to result in movement of said locking unit to the locked position, where said first slope is pushed by the lateral plate such that said first flexible portion deforms and leaves the accommodating space, where said deformable portion of said main body is separated from said inclined surface portion and restores to drive said fixing pin to engage the fixing hole of the electronic device, and where said second engaging structure engages said first engaging structure. |
