For example, the first engaging feature 84 is a protrusion, and the second engaging feature 86 and the third engaging feature 88 are positioning holes, but the present invention is not limited thereto.

As shown in FIG. 6, the second supporting frame 34 can be operated to locate at a first position P1 relative to the first bracket 22. Wherein, the at least one driving part 67 of the driving structure 63 is located at a position corresponding to the contact part 75 of the at least one mounting member 71, and the mounting part 73 of the at least one mounting member 71 can be entirely or partially retracted into the through hole H of the end wall 72.

As shown in FIG. 7, the second supporting frame 34 can be operated to move relative to the first bracket 22 along a first direction D1 from the first position P1 to a second position P2. Wherein, during a process of the second supporting frame 34 being moved from the first position P1 to the second position P2, the at least one driving part 67 of the driving structure 63 is configured to drive the at least one mounting member 71 to move relative to the side wall 68 of the first bracket 22 through the contact part 75, such that the mounting part 73 of the at least one mounting member 71 can be entirely or partially extended out of the through hole H of the end wall 72. Wherein, through arrangement of the elongated hole 80 and the connecting member 81 of the limiting structure 78, the second supporting frame 34 can be moved relative to the first bracket 22 within a limited range between the first position P1 and the second position P2.

As shown in FIG. 8, the arm part 79b of the fastening member 79 extends beyond the end wall 72 from the side wall 68 of the first bracket 22, such that the fastening part 79a is in front of the at least one mounting member 71 and/or the end wall 72. Furthermore, when the second supporting frame 34 is located at the first position P1 relative to the first bracket 22, the first engaging feature 84 of the elastic member 82 is engaged with the second engaging feature 86 of the first bracket 22, such that the second supporting frame 34 can be temporarily held at the first position P1.

Preferably, as shown in FIG. 9, when the second supporting frame 34 is operated to move relative to the first bracket 22 along the first direction D1 from the first position P1 to the second position P2, the first engaging feature 84 of the elastic member 82 is engaged with the third engaging feature 88 of the first bracket 22, such that the second supporting frame 34 can be temporarily held at the second position P2.

As shown in FIG. 10, the auxiliary elastic member 77 is preferably mounted in an accommodating room R of the base 70. The auxiliary elastic member 77 is configured to abut against an inner wall 89 of the accommodating room R and the mounting part 73 of the at least one mounting member 71.

Wherein, the at least one driving part 67 of the driving structure 63 is located at the position corresponding to the contact part 75 of the at least one mounting member 71, and the mounting part 73 of the at least one mounting member 71 can be entirely or partially retracted into the through hole H of the end wall 72. Preferably, when the second supporting frame 34 is located at the first position P1, the auxiliary elastic member 77 is in a first state (such as in a state of accumulating an elastic force), and the first engaging feature 84 of the elastic member 82 is engaged with the second engaging feature 86 of the first bracket 22, such that the second supporting frame 34 is held at the first position P1 and the auxiliary elastic member 77 is held in the first state.

As shown in FIG. 11, during the process of the second supporting frame 34 being moved from the first position P1 to the second position P2, the at least one driving part 67 of the driving structure 63 is configured to drive the at least one mounting member 71 to move relative to the side wall 68 of the first bracket 22, such that the mounting part 73 of the at least one mounting member 71 can be entirely or partially extended out of the through hole H of the end wall 72. Preferably, when the second supporting frame 34 is located at the second position P2, the auxiliary elastic member 77 is in a second state (such as in a state of not accumulating the elastic force), and the first engaging feature 84 of the elastic member 82 is engaged with the third engaging feature 88 of the first bracket 22, such that the second supporting frame 34 is held at the second position P2 and the auxiliary elastic member 77 is held in the second state. Preferably, when the mounting pat 73 of the at least one mounting member 71 is extended out of the through hole H, the at least one mounting member 71 is configured to abut against the base 70 or the end wall 72 through an extension leg 91.

Specifically, when the first engaging feature 84 of the elastic member 82 is operatively disengaged from the third engaging feature 88 of the first bracket 22, the second supporting frame 34 can return to the first position P1 from the second position P2 relative to the first bracket 22 along a second direction D2 (a direction opposite to the first direction D1).

As shown in FIG. 12, when a user is going to mount the slide rail mechanism 20 to the rack, the second supporting frame 34 is configured to be located at the first position P1 relative to the first bracket 22 in advance. Thereafter, the user can move the slide rail mechanism 20 toward the first post 26 laterally, so as to allow the fastening part 79a of the fastening member 79 to be located in front of the first post 76 for locking the first post 26 (or a target object). Moreover, the user can further move the slide rail mechanism 20 along the first direction D1, so as to allow a portion of the first bracket 22 (such as the end wall 72) to abut against the first post 26.

As shown in FIG. 13, the second supporting frame 34 can be operated to move relative to the first bracket 22 along the first direction D1 from the first position P1 to the second position P2. Wherein, during the processing of the second supporting frame 34 being moved from the first position P1 to the second position P2, the at least one driving part 67 of the driving structure 63 is configured to drive the at least one mounting member 71 to move along the first direction D1 relative to the side wall 68 of the first bracket 22 through the contact part 75, such that the mounting part 73 of the at least one mounting member 71 can be entirely or partially extended out of the through hole H of the end wall 72 to enter and pass through a corresponding mounting hole 90 of the first post 26, so as to mount the first bracket 22 of the slide rail mechanism 20 to the first post 26.

As shown in FIG. 14, after the first bracket 22 of the slide rail mechanism 20 is mounted to the first post 26, the first supporting frame 32 can be adjusted to move relative to the second supporting frame 34, so as to mount the second bracket 24 of the slide rail mechanism 20 to the second post 28. Therefore, the operation of mounting the slide rail mechanism 20 to the rack is completed. Wherein, since a process of mounting the second bracket 24 to the second post 28 is well known to those skilled in the art, no further illustration is provided for simplification.

As shown in FIG. 15, when the user is going to detach the first bracket 22 from the first post 26, the user can operate the second supporting frame 34 to move relative to the first bracket 22 along the second direction D2 from the second position P2 to the first position P1 (please also refer to FIG. 13 and FIG. 12), such that the mounting part 73 of the at least one mounting member 71 is detached from the corresponding mounting hole 90 of the first post 26 and retracted into the through hole H of the end wall 72 to enter the base 70. Accordingly, the fastening part 79a of the fastening member 79 can be moved away from the first post 26, so as to detach the first bracket 22 from the first post 26.

Therefore, the slide rail mechanism of the present invention is characterized in that:

1. The second supporting frame 34 is configured to drive the at least one mounting member 71 to move relative to the side wall 68 of the first bracket, wherein the at least one mounting member 71 is configured to be mounted to a corresponding mounting hole of a post (such as the first post 26).2.
