Description

Technical Field

[0001] The utility model relates to a slide rail device, in particular to a slide rail device with a synchronous blocking mechanism. Background Art

[0002] Generally, a server cabinet can accommodate multiple server chassis. The server chassis are installed in the server cabinet by means of a plurality of slide rail devices. Each slide rail device has an outer rail fixedly arranged on the server cabinet, a middle rail movably arranged on the outer rail, and an inner rail movably arranged on the middle rail. The server chassis are arranged on the inner rail. When the server chassis need to be repaired or replaced, the server chassis can be pulled out of the server cabinet by means of the telescopic function of the slide rail device. However, the existing slide rail devices do not have a limiting function to prevent the unexpected use of the server chassis on the same server cabinet from being pulled out by itself. Therefore, there is still room for improvement. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a slide rail device with a synchronous blocking mechanism that can solve at least one of the above problems.

[0004] The slide rail device with a synchronous blocking mechanism of the utility model is applicable to be arranged on a server cabinet. The server cabinet is provided with a plurality of such slide rail devices. The slide rail devices are connected to a linkage. Each slide rail device includes

[0005] An outer frame, which is suitable for being fixedly arranged on the server cabinet and includes a movable surface, an installation surface opposite to the movable surface and facing the server cabinet, an outer through groove connecting the movable surface and the installation surface, a first end, and a second end opposite to the first end;

[0006] An outer rail, which is arranged on the movable surface and includes a first outer surface, a second outer surface opposite to the first outer surface and facing the movable surface, and a movable groove corresponding to the position of the outer through groove;

[0007] A middle rail, which is movably arranged on the outer rail and includes a middle outer surface facing the outer rail;

[0008] A synchronous blocking mechanism, which includes a blocking member that can movably pass through the outer through groove and the movable groove and is suitable for fixedly connecting the linkage, and a blocking block arranged on the middle outer surface. The blocking block forms a blocking groove and a blocking convex part for the blocking member to movably extend into. The blocking groove has a blocking part extending vertically and an inclined part connecting the upper end of the blocking part and extending downward obliquely toward the second end. The blocking convex part is located between the blocking part and the inclined part;

[0009] When the middle rail moves towards the first end relative to the outer rail, the stopper is pushed by the stop block and moves downward along the inclined portion, thereby driving the linkage member to move downward. At the same time, the stoppers of other slide rail devices are driven to move downward along the corresponding stop portions to the side of the corresponding stop protrusions, so as to stop the middle rail of the other slide rail devices from moving relative to the corresponding outer rail.

[0010] In some embodiments, the stopper includes a movable portion that can movably pass through the outer through slot and the movable slot, a contact portion that connects the movable portion and abuts against the second outer surface, and a joint portion that connects the contact portion and is adapted to fixedly connect the linkage member.

[0011] In some embodiments, the movable portion and the joint portion are cylindrical, and the contact portion is disc-shaped.

[0012] In some embodiments, the synchronous stopper mechanism further includes two elastic members disposed on the first outer surface. Each elastic member forms a protrusion that protrudes into the movable slot and can abut against the movable portion.

[0013] In some embodiments, each elastic member includes a connecting portion connecting the first outer surface, two bending portions that extend in a wave shape from the upper and lower ends of the connecting portion towards the movable slot, and a pressing portion connecting the bending portions. Each pressing portion forms the protrusion.

[0014] In some embodiments, the outer rail further includes two protrusions formed on the first outer surface on both sides of the movable slot. The pressing portions are in the shape of long strips and can movably sleeved on the protrusions.

[0015] In some embodiments, the synchronous stopper mechanism further includes a pressing cover plate disposed on the first outer surface and partially covering the elastic members. The pressing cover plate has a through slot corresponding to the movable slot for the movable portion to pass through.

[0016] The utility model has at least the following effects: when the middle rail moves towards the first end relative to the outer rail, the stopper is pushed by the stop block and moves downward along the inclined portion, thereby driving the linkage member to move downward. At the same time, the stoppers of other slide rail devices are driven to move downward along the stop portions to the side of the stop protrusions, so as to stop the middle rail of the other slide rail devices from moving relative to the outer rail, achieving the effect of preventing the other slide rail devices from being pulled out.

[0035] Refer to Figures 1 to 3 , one embodiment of the slide rail device 10 with a synchronous blocking mechanism 5 of the present utility model is applicable to be arranged in a server cabinet (not shown in the figure). The server cabinet is provided with a plurality of such slide rail devices 10. The slide rail device 10 is connected to a linkage member 6. The linkage member 6 includes a linkage rod 61 extending vertically and two connecting pieces 62 horizontally extending transversely and connecting the linkage rod 61. The linkage rod 61 has two linkage holes 611. The connecting pieces 62 are applicable to engage with the server cabinet. Each slide rail device 10 includes an outer frame 1, an outer rail 2, a middle rail 3, an inner rail 4 and a synchronous blocking mechanism 5.

[0036] The outer frame 1 is applicable to be fixedly arranged on the server cabinet, and includes a movable surface 11, an installation surface 12 opposite to the movable surface 11 and facing the server cabinet, an outer through - slot 13 communicating the movable surface 11 and the installation surface 12, a first end 14 and a second end 15 opposite to the first end 14.

[0037] Refer to Figure 4The outer rail 2 is disposed on the movable surface 11 and includes a first outer surface 21, a second outer surface 22 opposite to the first outer surface 21 and facing the movable surface 11, an movable groove 23 corresponding to the outer through groove 13, and two protrusions 24 formed on the first outer surface 21 and located on both sides of the movable groove 23. The middle rail 3 can be movably disposed on the outer rail 2 and includes a middle outer surface 31 facing the outer rail 2. The inner rail 4 can be movably disposed on the middle rail 3 and is suitable for connecting to a server chassis (not shown).

[0038] See also Figures 4 to 6 The synchronous stop mechanism 5 includes a stopper 51 that can movably pass through the outer through slot 13 and the movable slot 23 and is suitable for fixing the linkage 6, a stopper 52 arranged on the middle outer side 31, a stopper bar 53 arranged on the middle outer side 31 against the stopper 52 and extending toward the second end 15 along the length direction of the middle rail 3, two stoppers 53 arranged on the first outer side 31, and a stopper 53 arranged on the second outer side 31.

[0039] The first outer surface 21 is provided with an elastic member 54 and a pressure cover sheet 55 which is arranged on the first outer surface 21 and partially covers the elastic member 54. The stopper 51 includes a movable portion 511 which can movably pass through the outer through groove 13 and the movable groove 23, a contact portion 512 which is connected to the movable portion 511 and abuts against the second outer surface 22, and a joint portion 513 which is connected to the contact portion 512 and is suitable for extending into the linkage hole 611 to fix the linkage member 6. The movable portion 511 and the joint portion 513 are cylindrical, and the joint portion 512 is disc-shaped; the radius of the movable portion 511 is smaller than the radius of the joint portion 513, and the radius of the joint portion 513 is smaller than the radius of the contact portion 512. The stopper 52 forms a stopper groove 521 and a stopper protrusion 522 for the stopper 51 to movably extend into.

[0040] See also Figure 7 The stopping groove 521 has a stopping portion 521a extending up and down and an inclined portion 521b connected to the upper end of the stopping portion 521a and extending downwardly toward the blocking bar 53, and the stopping protrusion 522 is located between the stopping portion 521a and the inclined portion 521b.

[0041] Each of the elastic members 54 is a thin sheet body made of an elastic material, and includes a connecting portion 541 connecting to the first outer surface 21, two bending portions 542 extending in a wave-like manner from the upper and lower ends of the connecting portion 541 towards the movable groove 23, and a pressing portion 543 connecting the bending portions 542. The pressing portion 543 is in the shape of a long strip loop and is movably sleeved on the bump 24, and each pressing portion 543 forms a protrusion 543a protruding into the movable groove 23 and capable of abutting against the movable portion 511. The pressing cover plate 55 has a through groove 551 corresponding to the position of the movable groove 23 and through which the movable portion 511 passes. Among them, the elastic member 54 and the pressing cover plate 55 are arranged on the first outer surface 21 by a plurality of positioning members 56, but this is not a limitation.

[0042] In an initial position, the movable portion 511 of the stopper 51 is located at the intersection of the stopper portion 521a and the upper end of the inclined portion 521b of the stopper groove 521, as Figure 7 and Figure 8 shown. When a user wants to take out a server chassis (not shown) from the server cabinet (not shown), the inner rail 4 is pulled to drive the middle rail 3 to move towards the first end 14 relative to the outer rail 2. At this time, the movable portion 511 of the stopper 51 is pushed by the stopper 52 and relatively displaced to move downward along the inclined portion 521b, as Figure 9 and Figure 10 shown. By fixing the linkage member 6 through the engaging portion 513 of the stopper 51, the linkage member 6 can be driven to move downward, so as to drive the stoppers 51 of other slide rail devices 10 to move downward along the corresponding stopper portions 521a to the vicinity of the corresponding stopper protrusions 522 at the same time, as Figure 11 shown. The middle rails 3 of the other slide rail devices 10 cannot move relative to the outer rail 2 because the stopper protrusions 522 are blocked by the movable portions 511, achieving the effect of preventing the other slide rail devices 10 from being pulled out.

[0043] BCPI - 240284 Page 6 / 6

[0044] Among them, by the protrusions 543a of the pressing portions 543 jointly protruding into the corresponding movable grooves 23 and abutting against the corresponding movable portions 511, it can assist in positioning the corresponding movable portions 511 at the position where the lower end of the corresponding stopper portion 521a and the corresponding stopper protrusion 522 are mutually blocked, as Figure 11As shown. During the process that the middle rail 3 of the slide rail device 10 corresponding to the pulled-out server cabinet continuously moves relative to the corresponding outer rail 2, due to the arrangement of the corresponding stop strip 53, it can continuously stop the corresponding movable part 511 to make it located below, ensuring that the linkage 6 is in a continuously downward moving state. Furthermore, it ensures that the middle rail 3 of the other slide rail devices 10 cannot move relative to the corresponding outer rail 2 because the corresponding stop convex part 522 is blocked by the corresponding movable part 511. Until the pulled-out server chassis returns into the server cabinet, when the movable part 511 of the corresponding stop member 51 returns to the initial position, it will drive the linkage 6 to move upward, making the movable parts 511 of the other slide rail devices 10 also return to the initial position, so as to release the blocking relationship with the corresponding stop convex part 522, ensuring that only one server chassis can be pulled out. It should be noted that in other embodiments, the stop strip 53 can be omitted because the design that the protrusions 543a of the pressing part 543 jointly protrude into the movable groove 23 has been able to assist in positioning the movable part 511 at the position where it is blocked by the lower end of the stop part 521a and the stop convex part 522.

[0045] In summary, the slide rail device 10 of the present utility model with the synchronous stop mechanism 5, when the middle rail 3 moves relative to the outer rail 2 towards the first end 14, the stop member 51 is pushed by the stop block 52 and moves downward along the inclined part 521b, thereby driving the linkage 6 to move downward. At the same time, it drives the stop members 51 of the other slide rail devices 10 to move downward along the corresponding stop part 521a to the side of the corresponding stop convex part 522 to stop the middle rail 3 of the other slide rail devices 10 from moving relative to the outer rail 2, achieving the effect of preventing the other slide rail devices 10 from being pulled out. Therefore, it can truly achieve the purpose of the present utility model.

[0046] The above is only the embodiment of the present utility model, and it cannot be used to limit the scope of implementation of the present utility model. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present utility model still belong to the scope of the present utility model.
