The driving structure 63 can be a fitting connected (e.g., fixedly connected) to the second supporting frame 34; alternatively, the driving structure 63 is integrally formed on the second supporting frame 34. In short, the driving structure 63 can be regarded as a part of the second supporting frame 34. Specifically, the driving structure 63 includes a connecting portion 65 and at least one driving portion 67. Here, the connecting portion 65 is connected to an end portion of the adjacent second supporting frame 34, and the at least one driving portion 67 is bent at an angle relative to the connecting portion 65, but the implementation is not limited thereto.

Preferably, the second support bracket 34 further comprises a resilient arm 64 and an abutting portion 66 disposed on the resilient arm 64, wherein the resilient arm 64 extends from the second support bracket 34.

Here, the base 70 is attached to the end wall 72 for example; the at least one mounting member 71 is movable relative to the side wall 68, for example, the at least one mounting member 71 is movably mounted on the base 70 and is displaceable relative to the side wall 68. Preferably, the end wall 72 has at least one through hole H, and the at least one mounting member 71 includes a mounting portion 73 and a contact portion 75. The mounting portion 73 is located at a position corresponding to the through hole H of the end wall 72, and the size of the mounting portion 73 is smaller than the size of the through hole H. Preferably, the contact portion 75 is connected to the mounting portion 73 and extends a distance relative to the mounting portion 73. Preferably, the slide rail mechanism 20 further comprises at least one auxiliary elastic member 77 for providing an elastic force to the at least one mounting member 71. Wherein the auxiliary elastic member 77 may be installed at the base 70.

As shown in fig. 2, 3 and 5, the driving structure 63 is configured to drive the at least one mounting member 71 to displace relative to the side wall 68 of the first bracket 22. Here, it is exemplified that the at least one driving portion 67 of the driving structure 63 is connected to the contact portion 75 of the at least one mounting member 71. Preferably, the slide rail mechanism 20 further includes a fastener 79. The fastener 79 may be a fitting connected (e.g., fixedly connected) to the first bracket 22; alternatively, the fastener 79 is integrally formed with the first bracket 22. In short, the fastener 79 can be considered as a part of the first bracket 22. Preferably, the fastener 79 has a buckle portion 79a and an arm portion 79b, and the buckle portion 79a is connected to the arm portion 79 b.

Further, one of the first bracket 22 and the second bracket 34 has a first wall section and a second wall section defining a space therebetween. Herein, taking the case that the upper portion and the lower portion of the side wall 68 of the first bracket 22 are respectively provided with a first wall section 74a and a second wall section 74b, a space 76 is defined between the first wall section 74a and the second wall section 74 b. The first bracket 22 and the second bracket 34 are movable relative to each other through the space 76. The first bracket 22 and the second bracket 34 can be regarded as a bracket device. Preferably, the bracket assembly further comprises the first support bracket 32, making it a bracket assembly having two sections of support brackets.

Preferably, one of the first bracket 22 and the second bracket 34 includes a limiting structure 78, and the second bracket 34 and the first bracket 22 can be displaced relative to each other within a limited range through the limiting structure 78. Preferably, the position-limiting structure 78 includes a slot 80 having a boundary and a connecting member 81 passing through a portion of the slot 80 for connecting the second supporting frame 34 to the first bracket 22. In this embodiment, the second supporting frame 34 has the long hole 80 as an example.

As shown in fig. 2, the slide rail mechanism 20 further includes an elastic member 82 attached to the second support frame 34. For example, the elastic member 82 can be connected to the second supporting frame 34 by riveting or screwing. The resilient member 82 has a first detent feature 84; on the other hand, the first bracket 22 includes a second latching feature 86 and a third latching feature 88, and the first latching feature 84 can be latched in one of the second latching feature 86 and the third latching feature 88. The first latching feature 84, the second latching feature 86, and the third latching feature 88 may be concave (or hole) or convex, or may be matched with a convex or concave (or hole) structure, for example, the first latching feature 84 is a convex portion, and the second latching feature 86 and the third latching feature 88 are positioning holes, but the implementation is not limited.

As shown in fig. 6, the second support bracket 34 is operable to be in a first position P1 relative to the first bracket 22. The driving portion 67 of the driving structure 63 is located corresponding to the contact portion 75 of the at least one mounting member 71, and the mounting portion 73 of the at least one mounting member 71 is located in the through hole H of the end wall 72.

Referring to fig. 7, the second supporting frame 34 is operable to move relative to the first bracket 22 from the first position P1 in a first direction D1 (or direction) to a second position P2. When the second supporting frame 34 is displaced from the first position P1 to the second position P2, the driving structure 63 is capable of responding to the displacement of the second supporting frame 34, so that the at least one driving portion 67 of the driving structure 63 can drive the at least one mounting member 71 to displace relative to the side wall 68 of the first bracket 22 through the contact portion 75 in the first direction D1, and the mounting portion 73 of the at least one mounting member 71 can fully or partially extend out of the through hole H of the end wall 72. Through the matching of the long hole 80 of the position-limiting structure 78 and the connecting member 81, the second supporting frame 34 can move within a limited range between the first position P1 and the second position P2 relative to the first bracket 22.

As shown in fig. 8, the arm 79b of the fastener 79 extends from the side wall 68 of the first bracket 22 beyond the front of the end wall 72 by a distance such that the fastener 79a is adjacent to the front of the at least one mounting member 71 and/or the end wall 72. Further, when the second supporting frame 34 is located at the first position P1 relative to the first bracket 22, it is preferable that the second supporting frame 34 can be temporarily kept at the first position P1 by the first latching feature 84 of the elastic member 82 latching to the second latching feature 86 of the first bracket 22.

As shown in fig. 9, when the second supporting frame 34 is operated to move relative to the first bracket 22 from the first position P1 to the second position P2 in the first direction D1, the second supporting frame 34 can be temporarily kept at the second position P2 by the first latching feature 84 of the elastic member 82 latching with the third latching feature 88 of the first bracket 22.

As shown in fig. 10, the auxiliary resilient member 77 is preferably installed in a chamber R of the base 70, and the auxiliary resilient member 77 abuts between an inner wall 89 of the chamber R and the mounting portion 73 of the at least one mounting member 71. Further, the second supporting frame 34 is located at the first position P1 relative to the first bracket 22. The driving portion 67 of the driving structure 63 is located corresponding to the contact portion 75 of the at least one mounting member 71, and the mounting portion 73 of the at least one mounting member 71 is located in the through hole H of the end wall 72. Preferably, when the second supporting frame 34 is at the first position P1, the auxiliary resilient member 77 is in a first state (e.g., a state of being stored with resilient force), and the second supporting frame 34 is caught by the second catching feature 86 of the first bracket 22 through the first catching feature 84 of the resilient member 82, so as to keep the auxiliary resilient member 77 in the first state as well as keep the second supporting frame 34 in the first position P1.

As shown in fig. 11, when the second supporting frame 34 is operated to be located at the second position P2 relative to the first bracket 22, in response to the second supporting frame 34 moving from the first position P1 to the second position P2, the at least one driving portion 67 of the driving structure 63 can drive the at least one mounting member 71 to move relative to the side wall 68 of the first bracket 22, so that the mounting portion 73 of the at least one mounting member 71 can fully or partially extend from the through hole H of the end wall 72 to the outside of the through hole H. Preferably, when the second supporting frame 34 is at the second position P2, the auxiliary resilient member 77 is in a second state (e.g., a state without elastic force), and the second supporting frame 34 is caught by the third catching feature 88 of the first bracket 22 through the first catching feature 84 of the resilient member 82, so as to maintain the second supporting frame 34 at the second position P2, and also maintain the auxiliary resilient member 77 at the second state. Preferably, when the mounting portion 73 of the at least one mounting member 71 extends out of the through hole H, the at least one mounting member 71 can abut against the base 70 or the end wall 72 through an extending leg 91.

It should be noted that after the first latching feature 84 of the resilient member 82 is operated to disengage from the third latching feature 88 of the first bracket 22, the second supporting frame 34 can be returned to the first position P1 from the second position P2 toward a second direction D2 (i.e., a direction opposite to the first direction D1) relative to the first bracket 22.

As shown in fig. 12, during the racking operation, the second supporting frame 34 is pre-positioned at the first position P1 relative to the first bracket 22, and then the operator can approach the slide rail mechanism 20 from a lateral position toward the first column 26, such that the fastening portion 79a of the fastening member 79 is positioned in front of the first column 26 for locking an object, such as the first column 26. Further, the operator can displace the slide mechanism 20 in the first direction D1 to make a portion (e.g., the end wall 72) of the first bracket 22 abut against the first column 26.

As shown in fig. 13, the second supporting frame 34 can be operated to move from the first position P1 to the first direction D1 to the second position P2 relative to the first bracket 22. When the second supporting frame 34 moves from the first position P1 to the second position P2, the driving structure 63 is capable of responding to the movement of the second supporting frame 34, so that the at least one driving portion 67 of the driving structure 63 can drive the at least one mounting member 71 to move relative to the side wall 68 of the first bracket 22 through the contact portion 75 in the first direction D1, and the mounting portion 73 of the at least one mounting member 71 can fully or partially extend out of the through hole H of the end wall 72 and enter the at least one mounting hole 90 of the first bracket 26, so that the first bracket 22 of the slide rail mechanism 20 is mounted on the first bracket 26.

As shown in fig. 14, after the first bracket 22 of the slide mechanism 20 is mounted on the first column 26, the second bracket 24 of the slide mechanism 20 can be mounted on the second column 28 by adjusting and displacing the first support bracket 32 relative to the second support bracket 34, so as to complete the operation procedure of mounting the slide mechanism 20 on the rack. Since the mounting of the second bracket 24 to the second mast 28 is within the skill of one of ordinary skill in the art, further description is omitted herein for the sake of brevity.

As shown in fig. 15, when the first bracket 22 is to be detached from the first mast 26, the operator can operate the second supporting frame 34 to return to the first position P1 (see fig. 13 and 12 in sequence) from the second position P2 to the second direction D2 relative to the first bracket 22, so that the mounting portion 73 of the at least one mounting member 71 is separated from the at least one mounting hole 90 of the first mast 26, retracted into the through hole H of the end wall 72 and into the base 70, and the fastening portion 79a of the fastening member 79 is separated from the front of the first mast 26, so as to detach the first bracket 22 from the first mast 26.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

1. the second support bracket 34 is operable to move the at least one mounting member 71 relative to the side wall 68 of the first bracket 22, wherein the at least one mounting member 71 is configured to be mounted to at least one mounting hole 90 of a column (e.g., the first column 26).

2. The fastener 79 is fixed relative to the first bracket 22, and the fastening portion 79a of the fastener 79 is adjacent to the front of the at least one mounting member 71 and/or the end wall 72, wherein the fastening portion 79a of the fastener 79 can be used to lock a column (e.g., the first column 26).

3. The elastic member 82 can be engaged with the second engaging feature 86 or the third engaging feature 88 of the first bracket 22, so that the second supporting frame 34 can be temporarily kept at the first position P1 or the second position P2 relative to the first bracket 22.

Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
