Description

Technical Field

[0001] This utility model relates to a slide rail with a support structure, specifically referring to a pre-set cabinet and pre-set chassis adapted to an industrial server. During the movement or reconnection of the slide rail relative to another slide rail, two working features provide a pre-set space between the slide rail and the other slide rail, allowing the components mounted on the slide rails to move smoothly. Background Technology

[0002] Industrial server chassis are frequently pulled out or reconnected to pre-installed cabinets via multiple slide rails. However, well-known pre-installed cabinets are mainly designed in two sizes. The multiple slide rails are composed of components such as an inner frame, middle frame, outer frame, multiple ball bearings, and ball bearing seats. The fixed distance between the chassis and the cabinet has a design tolerance. When the tolerances of the chassis and cabinet accumulate, they exert excessive pressure on the multiple slide rails. This pressure causes the slide rails to deform, which in turn leads to the obstruction and jamming of the components installed on each slide rail. Therefore, how to avoid obstruction and jamming of the multiple slide rails and the components installed on them is a direction that relevant industry professionals urgently want to research and improve.

[0003] In the existing technology, a plurality of balls are movably connected to a ball seat between the inner frame and the middle frame, and a plurality of balls are movably connected to a ball seat between the middle frame and the outer frame. The ball seat houses a plurality of balls, allowing a plurality of slide rails to move smoothly relative to it. In the conventional installation method, each slide rail has a groove to support part of the ball seat structure, and each slide rail also has a ball groove to accommodate a plurality of balls. The plurality of balls are movably mounted on the ball seat, and they are aligned with the groove and ball groove respectively. Because there is no design to limit the plurality of balls from falling off, the plurality of balls often fall off, and the assembly process is time-consuming. Therefore, how to avoid the accidental fall off of the plurality of balls and the time-consuming assembly process is the direction that relevant operators in this industry urgently want to research and improve.

[0004] However, during the disassembly and reconnection of the inner frame to the middle frame, the conventional installation method involves installing a stop on the inner or middle frame to release the ball bearing from its confinement at the front end of the middle frame, allowing the ball bearing to be pulled into the middle frame by the inner frame. Because there is no double ball bearing release design, when the stop fails to release the ball bearing, unexpected frictional resistance is generated, leading to damage to the ball bearing and wear on the frame. Therefore, how to avoid abnormal ball bearing release is a direction that relevant industry players urgently want to study and improve. Summary of the Invention

[0005] The main purpose of this utility model is to provide a slide rail with a support structure, wherein the first rail is slidably connected to the second rail and can drive the limiting component, and the second rail is provided with two working features for the first rail to resist, thereby improving the stability of the limiting component's movement within the preset space.

[0006] Another objective of this utility model is a slide rail with a support structure, wherein the first rail is slidably connected to the second rail, and the second rail is provided with two working features. When the sliding member is installed on the second rail, the two working features are used to limit the sliding member from sliding outside the second rail, thereby simplifying the assembly process and improving efficiency.

[0007] To achieve the above objectives, the present invention employs a technical means comprising: a first rail and a second rail, wherein a limiting component is provided on one side of the first rail, and the second rail is slidably connected to the first rail, and the second rail is provided with two working features for the first rail to abut against, the two working features and the first rail forming a preset space, the preset space being used for the movement of the limiting component.

[0008] To achieve the above objectives, another technical means adopted by this utility model includes: a first rail, a second rail, and a slider. A limiting component is provided on one side of the first rail, and the second rail is provided with two working features for the first rail to abut against. The slider is disposed between the first rail and the second rail so that the first rail can move relative to the second rail, and the two working features are used to limit the movement of the slider in a first direction.

The anti-drop device 4 includes: a limiting space 40, an operating member 41, a left stop member 42, an elastic member 43, a right stop member 44 and a second working feature 45. The left stop member 42, the right stop member 44 and the elastic member 43 form a limiting component A, and the limiting space 40 is formed between the left stop member 42 and the right stop member 44.

[0076] Please refer to Figures 2, 10, and 11. Each partition 34 has at least one sliding hole 340 extending from the bend towards the end. The sliding member 3 has at least one rolling element 31 inserted into the at least one sliding hole 340. Each sliding hole 340 has a recess 341 at both ends extending from each partition 34, which cooperates with the at least one rolling element 31. There is a gap between each of the two recesses 341 and the at least one rolling element 31. Each sliding hole 340 has a protrusion 342 at the other two ends extending from each partition 34. The two protrusions 342 are used to position the at least one rolling element 31 in the at least one sliding hole 340 of each partition 34. In addition, the end faces of the two protrusions 342 each have a guide slope (not shown in the figure). The at least one rolling element 31 is movably connected to the two first transverse walls 12 and the two second transverse walls 23.

[0077] This utility model is described in the example of at least one concave portion 341 being arc-shaped and at least another concave portion 341 being rectangular, and each convex portion 342 having a vertically flat end face. Each concave portion 341 may also be rhomboid, trapezoidal or other geometric shape, and each convex portion 342 end face may be inclined, arc-shaped or other shape from top to bottom toward the rolling body 31. Each concave portion 341 and each convex portion 342 is sufficient to accommodate the rolling body 31 and allow it to rotate smoothly. The embodiments are not intended to limit the patent scope of this utility model.

[0078] Please refer to Figure 3 again, wherein the first positioning part 51 has an inclined wall 511 and a straight wall 512, the straight wall 512 being opposite to the inclined wall 511, the inclined wall 511 being corresponding to one side of the body 32 opposite to the second longitudinal wall 21. Furthermore, the first working feature 13 and the second working feature 45 are respectively corresponding to the inclined wall 511, and the end of the second positioning part 52 has a guide angle 521 corresponding to the first working feature 13 and the second working feature 45 respectively.

[0079] This utility model is illustrated by illustrating an embodiment in which the first working feature 13 is a single piece manufactured first and then assembled to the first longitudinal wall 11, and the second working feature 45 is a separate piece manufactured first and then assembled to the operating member 41. The single piece can be integrally formed on the first longitudinal wall 11, and the other single piece can be integrally formed on the operating member 41, without limitation. Similarly, the working feature 221 is integrally formed on the slide groove 22, which is also illustrated by illustrating an embodiment. The working feature 221 can be initially manufactured from a composite material of metal and non-metal materials and then assembled onto the slide groove 22, without limitation. The stop portion 24 is integrally formed on the rear end of the second longitudinal wall 21, which is also illustrated by illustrating an embodiment. The stop part 24 can be made of a composite material of metal and non-metal and then assembled to the rear end of the second longitudinal wall 21, but is not limited thereto; the rolling element 31 is a ball bearing for illustrative purposes only, but the rolling element 31 can be a roller or other rolling element, but is not limited thereto; the stop 6 is a sheet metal part for illustrative purposes only, and the stop 6 can be made of a non-metallic composite material, but is not limited thereto; the auxiliary part 5 is a fastener made of stainless steel in the form of a thin sheet, the thickness of which is sufficient to be flexible, the above is only for illustrative purposes only, and does not limit its manufacturing and assembly methods, and the auxiliary part 5 can be made of medium carbon steel, other metal materials and non-metallic composite materials, but is not limited thereto.

[0080] Please refer to Figures 2, 5, 10, and 11. When the first rail 1 is moved in a first direction D1 by a force applied, the first rail 1 drives the sliding member 3 to move in the same direction. Each first transverse wall 12 of the first rail 1 pushes the sliding member 3 to the at least one rolling element 31 located on each partition 34. The at least one rolling element 31 rolls in the at least one sliding hole 340 of each partition 34, the bead groove of each first transverse wall 12, and the bead groove of each second transverse wall 23. The two... The protrusion 342 is used to limit the rolling of at least one rolling element 31, and the guide slope of the two protrusions 342 is used to limit the movement of at least one rolling element 31 toward the body 32. The body 32 of the slider 3 moves relative to the second longitudinal wall 21 of the second rail 2. Each bearing part 33 of the slider 3 moves relative to each groove 22. Then, the end of each first transverse wall 12 of the first rail 1 slides on each working feature 221, and at the same time, the notch 35 of the slider 3 disengages from the stop part 24 of the second rail 2.

[0081] Continuing from the above, by means of the spaced arrangement of each partition 34, the two bearing portions 33 of the sliding member 3 can smoothly slide on the two grooves 22 of the second rail 2, and each partition 34 can smoothly slide between the two first transverse walls 12 and the two second transverse walls 23 of the first rail 1, which has the effect of adapting to the deformation of the first rail 1 or the second rail 2 and improving the overall stable sliding of the sliding member 3.

[0082] Please refer to Figures 5 through 7. When the sliding member 3 is driven by the first rail 1 to slide in the same direction, the sliding member 3 will contact the auxiliary member 5, causing the auxiliary member 5 to elastically deform. The body 32 of the sliding member 3 pushes the first positioning part 51 of the auxiliary member 5. The body 32, relative to the second longitudinal wall 21, presses against the inclined wall 511 of the first positioning part 51, causing the first positioning part 51 to partially disengage from the first opening 211. Furthermore, as the sliding member 3 continues to move, its body 32... The other notch 36 disengages from the first positioning part 51, the opening 37 of the body 32 is positioned opposite the first opening 211, causing the auxiliary member 5 to elastically reset, the first positioning part 51 enters the opening 37 through the first opening 211, the straight wall 512 of the first positioning part 51 engages in the opening 37 and the first opening 211, the other notch 36 of the body 32 abuts against the second positioning part 52 of the auxiliary member 5, thereby locking the sliding member 3 to the end of the second rail 2 to form a locked state.

[0083] Please refer to Figures 4, 8 to 10. When the first rail 1 continues to move in the same direction relative to the second rail 2, the limiting component A of the anti-detachment device 4, without any external force, is driven by the first rail 1. The lower part of the left stop 42 of the limiting component A abuts against one end of the stop 6, causing the left stop 42 to pivot upwards. The left stop 42 moves away from the stop portion 411 of the operating member 41. The left stop 42, in conjunction with the elastic member 43, elastically deforms. Furthermore, when the first rail 1 continues to move in the same direction, its… The left stop 42 passes over the stop 6, and the elastic member 43 elastically resets. The elastic member 43 drives the left stop 42 to pivot and reset, and abuts against one end of the stop portion 411. The right stop 44 of the limiting component A abuts against the other end of the stop portion 411. The stop 6 enters the limiting space 40 of the anti-drop device 4. The left stop 42 abuts against one end of the stop 6, and the right stop 44 abuts against the other end of the stop 6, thereby forming an anti-drop state, so that the first rail 1 is locked in an extended position relative to the second rail 2.

[0084] Please refer to Figures 10 to 12, where when the first rail 1 is locked in the extended position relative to the second rail 2, and when it applies force to the operating member 41 from an initial position P toward the first direction D1, one side of the stop portion 411 of the operating member 41 abuts against and pushes the left stop member 42 of the limiting component A. The left stop member 42, in conjunction with the elastic member 43, undergoes another elastic deformation, causing the left stop member 42 to pivot upwards. The left stop member 42 disengages from one end of the stop member 6. At this time, the first rail 1... When the second rail 2 is released from the extended position, the anti-detachment state is switched to a released anti-detachment state. The first rail 1 can then retract relative to the second rail 2 in the second direction D2, and the force applied to the operating member 41 stops. The elastic member 43 of the limiting component A elastically resets, and the elastic member 43 drives the left stop 42 to pivot downwards and reset. The stop portion 411 of the operating member 41 is pushed and pushed by the left stop 42 to reset in the second direction D2, which is opposite to the first direction D1.

[0085] Please refer to Figures 12 to 14. When the first rail 1 continues to move in the second direction D2 under force, its second working feature 45 pushes the auxiliary member 5 to elastically deform. The second working feature 45 presses against the guide angle 521 of the second positioning part 52 on one side relative to the second longitudinal wall 21. Simultaneously, the second positioning part 52, in conjunction with the first positioning part 51, causes the straight wall 512 to disengage from the opening 37, thus partially disengaging the straight wall 512 from the first opening 211 and the other notch of the body 32. 36. When the slider 3 and the auxiliary member 5 leave the second positioning part 52, the slider 3 and the auxiliary member 5 switch from the locked state to the released state. When the second working feature 45 passes the auxiliary member 5, the slider 3 disengages from the auxiliary member 5, and the auxiliary member 5 elastically resets. The second positioning part 52 engages with the second opening 212, and the straight wall 512 of the first positioning part 51 engages with the first opening 211, so that the slider 3 can be driven by the first rail 1 to slide in the second direction D2, and the first rail 1 can be retracted into the second rail 2.

[0086] Please refer to Figures 3, 10, 15 to 17. When the first rail 1 is locked in the extended position relative to the second rail 2, and it applies force to the operating member 41 from an initial position P toward the second direction D2, the other side of the stop portion 411 of the operating member 41 abuts against and pushes the right stop member 44 of the limiting component A. The right stop member 44, in conjunction with the elastic member 43, elastically deforms, causing the right stop member 44 to pivot upwards, disengaging from the other side of the stop member 6. At this point, the first rail 1 is released from the extended position relative to the second rail 2, thereby switching the anti-detachment state to a released anti-detachment state. The first rail 1 can then be disassembled relative to the second rail 2 in the first direction D1, and the force applied to the operating member 41 stops. The elastic element 43 of the limiting component A elastically resets, and the elastic element 43 drives the right stop 44 to pivot and reset. The other side of the stop portion 411 of the operating member 41 is pushed and pushed by the right stop 44 to reset in the second direction D2.

[0087] Please refer to Figures 8 through 17 through 19. When the first rail 1 reconnects to the second rail 2, it moves in the second direction D2. At this time, the sliding member 3 and the auxiliary member 5 are in the locked state. The first working feature 13 pushes the auxiliary member 5 to elastically deform. The first working feature 13 presses against the guide angle 521 of the second positioning part 52 on the side opposite to the second longitudinal wall 21. The second positioning part 52 is linked to the first positioning part 51, causing the straight wall 512 of the first positioning part 51 to disengage from the opening 3. 7. The straight wall 512 is partially disengaged from the first opening 211, and the other notch 36 of the body 32 is disengaged from the second positioning part 52. At this time, the sliding member 3 and the auxiliary member 5 are switched from the locked state to an unlocked state. The first working feature 13 passes over the auxiliary member 5, the sliding member 3 is disengaged from the auxiliary member 5, and the auxiliary member 5 is elastically reset. The second positioning part 52 is engaged with the second opening 212, and the straight wall 512 is engaged with the first opening 211. At this time, the sliding member 3 can be driven by the first rail 1 to slide in the second direction D2.

[0088] Continuing from the above, the inclined wall 511 and the straight wall 512 of the first positioning part 51, the guide angle 521 of the second positioning part 52, and the switching process between the locked state and the unlocked state of the sliding member 3 and the auxiliary member 5 do not require additional tools or cumbersome operations. The other notch 36 of the body 32 pushes the inclined wall 511 in a smooth manner, which has the effect of smooth guidance and noise reduction. The straight wall 512 can be engaged with the first opening 211 and the opening 37 respectively. The second positioning part 52 can also be engaged with the second opening 212, which improves the stability of the switching state of the sliding member 3 and the auxiliary member 5. The first working feature 13 and the second working feature 45 correspond to and push the guide angle 521, which also has the effect of smooth guidance and noise reduction.

[0089] Please refer to Figures 10 and 18. When the first rail 1 continues to move in the second direction D2, the limiting component A of the anti-detachment device 4 is not subject to any external force. The operating member 41 and the limiting component A are respectively driven by the first rail 1. The right stop 44 abuts against the other end of the stop 6, causing the right stop 44 to pivot upwards again. The right stop 44 moves away from the stop portion 411 of the operating member 41. The right stop 44, in conjunction with the elastic member 43, elastically deforms again. When the first rail 1 continues to move in the same direction, its right stop 44 passes the stop 6, and the elastic member 43 elastically resets again. The elastic member 43, in conjunction with the right stop 44, pivots and resets again. The stop 44 abuts against the other end of the stop portion 411 again, the left stop 42 of the limiting component A abuts against one end of the stop portion 411 again, the stop 6 enters the limiting space 40 again, the left stop 42 abuts against one end of the stop 6 again, and the right stop 44 abuts against the other end of the stop 6 again. At this time, the anti-detachment state is switched back to the anti-detachment state, so that the first rail 1 is locked in an extended position relative to the second rail 2 again, and the operating member 41 is forced again from the initial position P toward the first direction D1. The anti-detachment device 4, the stop 6 and the first rail 1 are in the anti-detachment state relative to the second rail 2. Their cooperating components and structures are as described in the previous paragraph

[0023] , and will not be repeated here.

[0090] Please refer to Figures 12 to 14, 17 and 19 for further explanation. The second working feature 45 located on the operating member 41 corresponds to the auxiliary member 5 to provide an additional release mechanism. After the first rail 1 is reconnected to the second rail 2, under normal operation, the sliding member 3 and the auxiliary member 5 are first pushed by the first working feature 13 to put them in the released state. When the first rail 1 is released relative to the second rail 2 in the extended position and is in the released anti-drop state, when the first rail 1 is subjected to force to continue moving in the second direction D2, the second working feature 45 pushes the auxiliary member 5 to elastically deform. Its cooperating components and structure are as described in the previous paragraph

[0024] , and will not be repeated here.

[0091] Finally, referring to Figures 10, 15, 16, and 19, in actual operation, the first longitudinal wall 11 of the first rail 1, on the side away from the limiting component A, is installed in a preset server chassis (not shown in the figure), while the second rail 2 and the third rail 7 are installed in a preset cabinet. When the technician connects the preset server chassis installed on the other side of the first rail 1 to the second rail 2 for the first time and reconnects it, the two working features 221 of the two slides 22 are configured to increase the space H formed by the first longitudinal wall 11 relative to the second longitudinal wall 21. The preset space H provides the anti-drop device 4 with a space for movement, so that the operating member 41 can smoothly move the left stop 42, the elastic member 43, and the right stop 44 of the limiting component A during the linkage process, thereby improving the stability of the anti-drop device 4 and its service life.

[0092] In this invention, the sliding member 3 and the auxiliary member 5 enter the locked state to ensure that before the first rail 1 retracts into the second rail 2, the front end of the sliding member 3 is located at the front end of the second rail 2, and the anti-detachment device 4 is located on the second working feature 45 of the operating member 41 corresponding to the auxiliary member 5. This constructs a dual release mechanism during the reconnection of the first rail 1 to the second rail 2. The first working feature 13 first pushes and passes over the auxiliary member 5, causing the auxiliary member 5 to elastically deform and reset. If the sliding member 3 fails to detach from the auxiliary member 5, the sliding member 3 and the auxiliary member 5 remain in the locked state and fail to switch to the released state. At this time, the sliding member 3 and the auxiliary member 5 are in an abnormal locked state. The second working feature 45 then pushes the auxiliary member 5, causing the sliding member 3 and the auxiliary member 5 to switch from the abnormal locked state to the released state. This allows the user to complete the dual release mechanism in a single action, improving efficiency and effectively preventing component detachment, thereby enhancing safety and durability.
