The second support bracket 34 is displaceable relative to the first support bracket 32. For example, but not limited to, a portion of the second support bracket 34 is movably mounted to the channel 58 of the first support bracket 32, and the second support bracket 34 is displaceable relative to the first support bracket 32 through the channel 58 of the first support bracket 32. The second support bracket 34 includes a resilient arm 67 and an abutting portion 68 disposed on the resilient arm 67, wherein the resilient arm 67 extends from the second support bracket 34.

Preferably, the second support bracket 34 includes a support structure 70, an extension 72 and a guide structure 74. The extension 72 is located between the support structure 70 and the guide structure 74.
The first bracket 22 and the second bracket 34 are movable relative to each other. Preferably, the first bracket 22 is movably mounted to the second support bracket 34 and is adjustable to be positioned adjacent the first end 40a of the rail member 30. The first bracket 22 includes a side wall 76, an end wall 77 and at least one mounting member 78. The end wall 77 is substantially vertically connected to the side wall 76; the at least one mounting member 78 is disposed on the end wall 77, and two mounting members 78 are illustrated. The slide mechanism 20 further includes a fastener 80 movably mounted to the first bracket 22. The first bracket 22 and the second bracket 34 (and the first bracket 32) can be regarded as a bracket device.
Further, one of the first bracket 22 and the second bracket 34 has a first wall and a second wall defining a space therebetween. Herein, taking the example that the upper portion and the lower portion of the side wall 76 of the first bracket 22 respectively have a first wall 82a and a second wall 82b, a space 84 is defined between the first wall 82a and the second wall 82 b. The first bracket 22 and the second bracket 34 are movable relative to each other through the space 84. Preferably, the fastener 80 is pivotally connected to the first bracket 22 through a shaft 85, for example, the fastener 80 is pivotally connected to the first wall 82 a; the fastener 80 includes a supporting leg 86 and a guiding leg 88. Preferably, the fastener 80 further comprises a mounting portion 90, a fastening portion 92 and an arm portion 94 located between the mounting portion 90 and the fastening portion 92. Here, the supporting leg 86 and the guiding leg 88 are spaced apart from each other. The supporting legs 86 and the guiding legs 88 are bent relative to the mounting portion 90, and the supporting legs 86 and the guiding legs 88 are located in the space 84 adjacent to the first bracket 22.
Preferably, one of the first bracket 22 and the second bracket 34 includes a limiting structure 96, 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 96. Here, the limiting structure 96 can be a long hole with a boundary, and the slide rail mechanism 20 further includes a connecting member 98 passing through a portion of the limiting structure 96 for connecting the second supporting frame 34 to the first bracket 22.
Preferably, the first bracket 22 includes a first supporting protrusion 23 located on one of the upper and lower sides (e.g., upper side) of the space 84 for supporting the second supporting frame 34, and the second supporting frame 34 includes a front supporting protrusion 35a located on the other of the upper and lower sides (e.g., lower side) of the space 84 for supporting a second wall 82b of the first bracket 22 (see fig. 24). Preferably, the first support frame 32 includes a second support protrusion 33 located on one of the upper and lower sides (e.g., upper side) of the channel 58 for supporting the second support frame 34, and the second support frame 34 includes a rear support protrusion 35b located on the other of the upper and lower sides (e.g., lower side) of the channel 58 for supporting the lower support wall 54b of the first support frame 32.
Preferably, the slide mechanism 20 further includes an elastic member 100 attached to the second support frame 34. For example, the elastic member 100 can be connected to the second supporting frame 34 by riveting or screwing. The resilient member 100 has a first detent feature 102; on the other hand, the first bracket 22 includes a second latching feature 104, and the first latching feature 102 can latch in the second latching feature 104. The first latching feature 102 and the second latching feature 104 may be concave (or hole) or convex, or may be a matching structure of convex or concave (or hole), for example, the first latching feature 102 is a convex portion, and the second latching feature 104 is a positioning hole, but the implementation is not limited.
The reinforcing member 36 is mounted on the rail 30 and the first support frame 32 for reinforcing the supporting ability between the rail 30 and the first support frame 32. Specifically, the reinforcing member 36 includes a second engaging structure 106, and the reinforcing member 36 can be used to engage the first engaging structure 42 of the rail member 30 through an engaging portion 108 of the second engaging structure 106. Herein, the second latching structure 106 is exemplified by an elastic fitting, which can be connected to the reinforcing member 36 by riveting or screwing, and thus can be regarded as a part of the reinforcing member 36. The first latching structure 42 and the latching portion 108 of the second latching structure 106 may be concave (or hole) or convex, or may be a structure matching convex or concave (or hole), but the implementation is not limited thereto. On the other hand, the first bracket 22 includes a releasing structure 109 for releasing the latching portion 108 of the second latching structure 106 of the reinforcing member 36 from the first latching structure 42 of the rail member 30.
Preferably, the reinforcing member 36 further includes a body portion 110 and at least one clasping portion 112 located on one side of the body portion 110. Here, two clasping portions 112 are taken as an example. The two clasping portions 112 can be used to support the upper portion and the lower portion of the rail 30, respectively. The other side of the main body 110 of the reinforcing member 36 is connected to the first supporting frame 32. For example, the reinforcing member 36 can be fixedly connected to the first supporting frame 32 by riveting, screwing, welding or clipping, so that the first supporting frame 32 and the reinforcing member 36 can be regarded as a whole.
As shown in fig. 5, one of the support leg 86 of the fastener 80 and the support structure 70 of the second support frame 34 includes at least one guide section. The at least one guiding section may be an inclined surface or an arc surface. Here, for example, the supporting structure 70 includes a first guiding section 120, and the supporting structure 70 further includes a supporting section 122 adjacent to the first guiding section 120. When the second supporting frame 34 is located at a first position P1 (also referred to as a position) relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 and the supporting leg 86 of the fastening member 80 define a predetermined distance therebetween, so that the supporting structure 70 of the second supporting frame 34 cannot provide the supporting leg 86 of the fastening member 80 to abut against, and the fastening member 80 can be located at a first state S1 (e.g., a locked state) relative to the at least one mounting member 78. It should be noted that in the first state S1, the fastening portion 92 of the fastening member 80 is close to the at least one mounting member 78.
As shown in fig. 6, when the second supporting frame 34 moves away from the first position P1 relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 can provide the supporting foot 86 of the fastening member 80 to abut or support, so that the fastening member 80 is no longer in the first state S1 relative to the at least one mounting member 78. The limiting structure 96 and the connecting member 98 are used to limit the displacement of the second supporting frame 34 and the first bracket 22 relative to each other.
Specifically, when the second supporting frame 34 is shifted from the first position P1 to a second position P2 in a first direction D1 relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 contacts the supporting leg 86 through the first guiding section 120 to drive the fastening device 80 to deflect an angle until the second supporting frame 34 is at the second position P2, the supporting section 122 of the supporting structure 70 of the second supporting frame 34 can provide the supporting leg 86 of the fastening device 80 to abut against, so that the fastening device 80 is switched from the first state S1 to a second state S2 (e.g., an unlocked state) relative to the at least one mounting device 78, and the supporting leg 86 abuts against through the supporting structure 70 of the second supporting frame 34, so that the fastening device 80 can be maintained in the second state S2; on the other hand, when the second supporting frame 34 is at the second position P2 relative to the first bracket 22, the guiding structure 74 of the second supporting frame 34 is located corresponding to the guiding foot 88 of the fastener 80. It should be noted that one of the guiding structure 74 of the second supporting frame 34 and the guiding leg 88 of the fastener 80 can be an inclined surface or an arc surface. In addition, when the second supporting frame 34 moves away from the first position P1 to the second position P2 relative to the first bracket 22, the fastener 80 can be in the second state S2. In the second state S2, the fastening portion 92 of the fastening member 80 is away from the at least one mounting member 78.
As shown in fig. 7, when the second supporting frame 34 is located at the first position P1 relative to the first bracket 22, the second supporting frame 34 is clamped to the second clamping feature 104 of the first bracket 22 through the first clamping feature 102 of the elastic member 100, and the first clamping feature 102 corresponds to a blocking wall 124 of the second clamping feature 104. Accordingly, the second supporting frame 34 can be maintained at the first position P1 relative to the first bracket 22.
As shown in fig. 8, the operation mode can be selected to directly operate the first latching feature 102 of the resilient member 100 to release the second latching feature 104 of the first bracket 22, and then displace the second supporting frame 34 relative to the first bracket 22 from the first position P1 to the first position D1 to the second position P2. Alternatively, the first latching feature 102 is designed to have a guiding mechanism, such as a slope or a cambered surface, relative to the second latching feature 104, so that the first latching feature 102 can be disengaged from the second latching feature 104 by the displacement of the second supporting frame 34 relative to the first bracket 22.
As shown in fig. 9, when the second supporting frame 34 is located at the second position P2 relative to the first bracket 22, the supporting structure 70 of the second supporting frame 34 can provide the supporting foot 86 of the fastening member 80 to abut against, so that the fastening member 80 is located at the second state S2 relative to the first column 26 (also referred to as "column"). Wherein the buckle portion 92 of the buckle 80 is away from the at least one mounting member 78, and the buckle portion 92 fails to lock the first mast 26. Further, when the first bracket 22 is to be installed on the first mast 26, the user can advance the first bracket 22 in a second direction D2 (e.g., a direction opposite to the first direction D1) such that the at least one mounting member 78 of the first bracket 22 enters the at least one hole 126 of the first mast 26 and the first bracket 22 abuts against the first mast 26.
As shown in fig. 10, when the first bracket 22 abuts against the first mast 26, the user can apply a force in the second direction D2 to move the second supporting frame 34 relative to the first bracket 22 from the second position P2 to the first position P1 in the second direction D2, so that the supporting structure 70 of the second supporting frame 34 cannot provide the supporting foot 86 of the fastener 80 to abut against, and the fastener 80 can be operated to recover the first state S1. Preferably, in response to the second supporting frame 34 being displaced from the second position P2 to the second direction D2 relative to the first bracket 22, the guiding structure 74 can drive the guiding leg 88 of the fastening member 80, so that the fastening member 80 is restored from the second state S2 to the first state S1. Wherein the fastening portion 92 of the fastener 80 is adjacent to the at least one mounting member 78, and the fastening portion 92 is capable of locking the first mast 26. Thus, the process of mounting the first bracket 22 to the first mast 26 is completed.
As shown in fig. 11, the operator may pre-stretch the slide mechanism 20 to make the slide mechanism 20 in an extended state having a first length L1. Specifically, the first supporting frame 32 can be displaced relative to the rail member 30 in the second direction D2 to be in an extended state relative to the supporting rail 38, and the second supporting frame 34 can be displaced relative to the first supporting frame 32 in the second direction D2 to be in an extended state.
The second limit feature 60 of the first support frame 32 can abut against the first limit feature 50 of the support rail 38 (see fig. 12).
Since the reinforcing member 36 is connected to the first supporting frame 32, in response to the displacement of the first supporting frame 32 relative to the rail member 30 and/or the supporting rail 38 in the second direction D2, the reinforcing member 36 can move to a predetermined position relative to the rail member 30, so that the reinforcing member 36 is clamped to the first clamping structure 42 of the rail member 30 by the clamping portion 108 of the second clamping structure 106 (see fig. 13). Accordingly, the first support frame 32 can be temporarily fixed relative to the rail 30 by the reinforcement member 36 being engaged with the rail 30. The second supporting frame 34 can be displaced in the second direction D2 relative to the first supporting frame 32 until the abutting portion 68 of the second supporting frame 34 enters the opening 62 of the first supporting frame 32, and the abutting portion 68 can abut against the contact wall 64 of the first supporting frame 32 (see fig. 13).
The support section 122 of the support structure 70 of the second support frame 34 can provide support or abutment for the support leg 86 of the fastener 80 (see fig. 14), so that the fastener 80 is in the second state S2 relative to the at least one mounting member 78. Wherein the fastening portion 92 of the fastening member 80 is away from the at least one mounting member 78; on the other hand, when the second supporting frame 34 is located at the second position P2 relative to the first bracket 22, the guiding structure 74 of the second supporting frame 34 is located corresponding to or adjacent to the guiding leg 88 of the fastener 80; on the other hand, the first latching feature 102 of the elastic member 100 of the second support bracket 34 is not latched to the second latching feature 104 of the first bracket 22.
When mounting the slide mechanism 20 to the first mast 26 and the second mast 28, a user can first advance the slide mechanism 20 in the second direction D2 such that the at least one mounting member 78 of the first bracket 22 faces the at least one hole 126 of the first mast 26.
As shown in fig. 15, after the at least one mounting member 78 of the first bracket 22 of the sliding track mechanism 20 enters the at least one hole 126 of the first column 26, the first bracket 22 (e.g., the end wall 77) can abut against the first column 26. Further, an operator may apply a force in the second direction D2, for example, apply a force to the slide rail mechanism 20 in the second direction D2, so that the second supporting frame 34 is displaced from the second position P2 to the second direction D2 relative to the first bracket 22 to the first position P1, in other words, the supporting section 122 of the supporting structure 70 of the second supporting frame 34 fails to provide the supporting foot 86 of the fastening 80 to abut against (this portion may refer to fig. 16), so that the fastening 80 is operable to return to the first state S1. Wherein, the first latching feature 102 of the elastic member 100 of the second supporting frame 34 can be latched to the second latching feature 104 of the first bracket 22. Further, in response to the displacement of the second supporting frame 34 relative to the first bracket 22, the guiding structure 74 can drive the guiding leg 88 of the fastening member 80, so that the fastening member 80 swings at an angle from the second state S2 to return to the first state S1. The fastening portion 92 of the fastening member 80 is adjacent to the at least one mounting member 78, and the fastening portion 92 is used for locking the first column 26. Preferably, when the fastener 80 is in the first state S1, the extending portion 72 of the second supporting frame 34 can provide the guiding foot 88 to abut against, so that the fastener 80 is kept in the first state S1. It should be noted that, as shown in fig. 14 and 16, the supporting foot 86 of the fastening member 80 has a second guiding section 128. In a process of moving the second supporting frame 34 relative to the first bracket 22 from the first position P1 to the first direction D1 (e.g., a direction opposite to the second direction D2) to the second position P2 through the first guiding section 120 or the second guiding section 128 (see fig. 16 and 14), the second supporting frame 34 can easily drive the fastener 80 to be switched from the first state S1 to the second state S2.
As shown in fig. 17, after completing the operation of mounting the first bracket 22 to the first mast 26, the operator can operate the rail 30 to displace in the first direction D1 relative to the second support bracket 34, so that the at least one mounting member 53 of the second bracket 24 enters the at least one hole 130 of the second mast 28. Since this part is within the technical scope that can be understood by a person skilled in the art, it is not described herein for the sake of brevity. It can be seen that the track mechanism 20 can be mounted to the first mast 26 and the second mast 28. It should be noted that the first bracket 22 and the second bracket 24 can be detached from the first mast 26 and the second mast 28, respectively (see fig. 17, 15 and 11 for brevity, which is not described herein again).
As shown in fig. 18 and 19, the slide rail mechanism 20 can be operated from the extended state to a retracted state. Specifically, an operator can displace the second supporting frame 34 in the first direction D1, wherein the releasing structure 109 of the first bracket 22 can contact the latching portion 108 of the second latching structure 106 of the reinforcing member 36 (see fig. 20).
As shown in fig. 21 and 22, when the second supporting frame 34 continues to be displaced in the first direction D1, the releasing structure 109 of the first bracket 22 can release the engaging portion 108 of the second engaging structure 106 of the reinforcing member 36 from the first engaging structure 42 of the rail member 30, so that the first supporting frame 32 can be displaced relative to the rail member 30. Preferably, one of the releasing structure 109 of the first bracket 22 and the latching portion 108 of the second latching structure 106 has an inclined surface or an arc surface, which helps the releasing structure 109 release the latching portion 108 of the second latching structure 106 of the reinforcing member 36 from the first latching structure 42 of the rail member 30.
As shown in fig. 23, after the first supporting frame 32 is relatively movable with respect to the rail 30, the first bracket 22, the second supporting frame 34, and the first supporting frame 32 can be folded with respect to the rail 30 and/or the supporting rail 38, so that the slide rail mechanism 20 is in the folded state and has a second length L2.
Fig. 24 is a schematic view illustrating the mounting of the slide rail mechanism 20 to the first column 26 and the second column 28. Specifically, when the rail 30 (only the supporting rail 38 is shown as the rail 30) carries an object 132 (e.g. an electronic device or a chassis), if the weight W1 of the object 132 is too heavy, the first supporting protrusion 23 and the front supporting protrusion 35a can support the space between the first bracket 22 and the second supporting frame 34. In addition, the first support frame 32 and the second support frame 34 can be supported by the second support protrusions 33 and the rear support protrusions 35 b. By this arrangement, the problem of possible sinking and falling of the slide rail and/or the bracket device relative to each other can be prevented. In short, unlike the load problem related to the slide rail and/or the bracket device shown in fig. 1, in the case of bearing a weight W1 or an external force, the present embodiment provides the first bracket 22, the second bracket 34 and the first bracket 32 to be maintained in a horizontal state as much as possible by the arrangement of the first supporting protrusions 23, the second supporting protrusions 33, the front supporting protrusions 35a and the rear supporting protrusions 35b, so as to prevent the problem of tilting or tilting of the first bracket 22, the second bracket 34 and the first bracket 32.
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:
1. with the help of the arrangement, an operator can finish the assembly and disassembly of the sliding rail mechanism to two machine columns of the rack by one person in front of the rack, and the operation is very convenient and fast.
2. The first support frame can be temporarily clamped on the rail piece through the reinforcing piece, so that when the first bracket is abutted to the first machine column and the sliding rail mechanism is operated to move forward in the direction of the first machine column, the second support frame is favorable for driving the fastener, the fastener is enabled to be converted into the first state from the second state, for example, the fastener can be enabled to be converted into the locking state from the unlocking state, and the fastener can be used for locking the machine column of the machine frame.
3. The reinforcement can be the activity of rail spare relatively, and the reinforcement contains the portion of clasping and can provide rail spare supporting role, so helps promoting the structural strength of rail spare.
4. Under the condition of bearing a weight or an external force, the first bracket, the second support frame and the first support frame can be kept in a horizontal state as much as possible through the arrangement of the first support convex body, the second support convex body, the front support convex body and the rear support convex body.
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.
