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] A general server cabinet can accommodate a plurality of 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 an outer frame, which is suitable for being fixedly arranged on the server cabinet, and includes an active surface, an installation surface opposite to the active surface and facing the server cabinet, an outer through groove communicating the active surface and the installation surface, a first end, and a second end opposite to the first end; an outer rail, arranged on the active surface, and includes a first outer surface, a second outer surface opposite to the first outer surface and facing the active surface, and an active groove corresponding to the position of the outer through groove; a middle rail, movably arranged on the outer rail, and includes a middle outer surface facing the outer rail; and a synchronous blocking mechanism, including a blocking member movably passing through the outer through groove and the active groove and suitable for fixedly connecting the linkage, arranged on page 2 / 6 of BCPI-240286

[0005] The outer stopper of the middle part, the stopper strip that is arranged on the outer side of the middle part and abuts against the stopper and extends along the length direction of the middle rail towards the second end, the linkage piece partially sleeved on the stopper, and the elastic piece arranged on the mounting surface and connecting the linkage piece. The stopper forms a stopper groove and a stopper protrusion for the stopper to movably extend into. The stopper groove has a vertically extending stopper portion and an inclined portion that communicates with the upper end of the stopper portion and extends downwardly and obliquely towards the stopper strip. The stopper protrusion is located between the stopper portion and the inclined portion. When the middle rail moves towards the first end relative to the outer rail, the stopper is pushed by the stopper and moves downward along the inclined portion, thereby driving the linkage piece to move downward, and at the same time driving the stoppers of other said slide rail devices to move downward along the stopper portion to beside the stopper protrusion to stop the middle rail of other said slide rail devices from moving relative to the outer rail. When the middle rail is reset relative to the outer rail, the elastic restoring force of the elastic piece can drive the linkage piece and the stopper to reset.

[0006] In some embodiments, the stopper includes a movable portion that movably passes through the outer through groove and the movable groove, an abutting portion that connects the movable portion and abuts against the second outer surface, and a joint portion that connects the abutting portion and is adapted to fixedly connect the linkage piece.

[0007] In some embodiments, the movable portion and the joint portion are cylindrical, and the abutting portion is disc-shaped.

[0008] In some embodiments, the stopper further includes a groove formed in the joint portion, and the linkage piece is engaged with the groove and is located on the mounting surface.

[0009] In some embodiments, the synchronous stopper mechanism further includes a fixing member arranged on the mounting surface, and the fixing member has an upper hook for connecting the upper end of the elastic piece.

[0010] In some embodiments, the linkage piece has a through groove for the stopper to pass through and a lower hook for connecting the lower end of the elastic piece.

[0011] 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 stopper and moves downward along the inclined portion, thereby driving the linkage piece to move downward, and at the same time driving the stoppers of other said slide rail devices to move downward along the stopper portion to beside the stopper protrusion to stop the middle rail of other said slide rail devices from moving relative to the outer rail, achieving the effect of preventing other said slide rail devices from being pulled out.

[0030] Referring to Figures 1 to 3 , an embodiment of the slide rail device 10 with a synchronous blocking mechanism of the present utility model is applicable to be set 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 6. The linkage 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 piece 62 is 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.

[0031] 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. The outer rail 2 is arranged 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, and a movable slot 23 corresponding to the position of the outer through - slot 13. The middle rail 3 is movably arranged in the outer rail 2 and includes a middle outer surface 31 facing the outer rail 2. The inner rail 4 is movably arranged in the middle rail 3 and is applicable to connect a server chassis (not shown in the figure).

[0032] Refer to Figures 4 to 7 , the synchronization blocking mechanism 5 includes a blocking member 51 that can movably pass through the outer through groove 13 and the movable groove 23 and is adapted to be fixed to the linkage member 6, a stopper 52 disposed on the middle outer surface 31, a stop bar 53 disposed on the middle outer surface 31 against the stopper 52 and extending along the length direction of the middle rail 3 toward the second end 15, a linkage piece 55 partially sleeved on the blocking member 51, an elastic member 54 disposed on the mounting surface 12 and connecting the linkage piece 55, and a fixing member 56 disposed on the mounting surface 12. The blocking member 51 includes a movable portion 511 that can movably pass through the outer through groove 13 and the movable groove 23 of BCPI-240286 Page 5 / 6

[0033] the movable portion 511 of the outer through groove 13 and the movable groove 23 and an abutting portion 512 connecting the movable portion 511 and abutting against the second outer surface 22, a joint portion 513 connecting the abutting portion 512 and adapted to extend into the linkage hole 611 to fix the linkage member 6, and a groove 514 formed in the joint portion 513. Among them, 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 abutting portion 512. The movable portion 511 and the joint portion 513 are cylindrical, and the abutting portion 512 is disc-shaped. The stopper 52 forms a blocking groove 521 for the blocking member 51 to movably extend into and a blocking convex portion 522. The blocking groove 521 has a blocking portion 521a extending vertically and an inclined portion 521b communicating with the upper end of the blocking portion 521a and extending downwardly and obliquely toward the stop bar 53. The blocking convex portion 522 is located between the blocking portion 521a and the inclined portion 521b.

[0034] The elastic member 54 is a tension spring. The linkage piece 55 is partially sleeved on the blocking member 51 and located on the mounting surface 12 by being engaged with the groove 514. The linkage piece 55 has a through groove 551 for the blocking member 51 to pass through and a lower hook 552( Figure 8 ) connecting the lower end of the elastic member 54. The fixing member 56 has an upper hook 561 connecting the upper end of the elastic member 54.

[0035] Refer to Figures 7 to 10 , in an initial position, the movable portion 511 of the blocking member 51 is located at the intersection of the blocking portion 521a and the upper end of the inclined portion 521b of the blocking groove 521, as shown in Figure 7 and Figure 8 . When a user wants to take out a server chassis (not shown) from the server cabinet (not shown), the inner rail 4 will be pulled to drive the middle rail 3 to move relative to the outer rail 2 toward the first end 14. At this time, the movable portion 511 of the blocking member 51 is pushed by the stopper 52 and relatively displaced downward along the inclined portion 521b, and the elastic member 54 is also stretched to accumulate an elastic restoring force, as shown in Figure 9 andFigure 10 As shown, by fixedly connecting the linkage member 6 through the engaging portion 513 of the stopper 51, the linkage member 6 can be further driven to move downward, so as to simultaneously drive the stoppers 51 of other said slide rail devices 10 to move downward along the stopper portion 521a to beside the stopper protrusion 522, as Figure 11 shown. The middle rail 3 of other said slide rail devices 10 cannot move relative to the outer rail 2 because the stopper protrusion 522 is blocked by the movable portion 511, achieving the effect of preventing other said slide rail devices 10 from being pulled out. 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 outer rail 2, due to the arrangement of the stop bar 53, the movable portion 511 can be continuously blocked to be located below, ensuring that the linkage member 6 is in a continuously downward moving state, and further ensuring that the middle rail 3 of other said slide rail devices 10 cannot move relative to the outer rail 2 because the stopper protrusion 522 is blocked by the movable portion 511. BCPI-240286 Page 6 / 6

[0036] Until the pulled-out server chassis returns to the server cabinet, the elastic restoring force of the elastic member 54 can drive the linkage piece 55 and the stopper 51 to reset and move upward. When the movable portion 511 of the stopper 51 returns to the initial position, the linkage member 6 will be driven to move upward, so that the movable portions 511 of other said slide rail devices 10 also return to the initial position, and the blocking relationship with the stopper protrusion 522 can be released, ensuring that only one server chassis can be pulled out.

[0037] In summary, the slide rail device 10 of the present utility model having the synchronous blocking mechanism 5, when the middle rail 3 moves towards the first end 14 relative to the outer rail 2, the stopper 51 is pushed by the stopper 52 and moves downward along the inclined portion 521b, thereby driving the linkage member 6 to move downward, and simultaneously driving the stoppers 51 of other said slide rail devices 10 to move downward along the stopper portion 521a to beside the stopper protrusion 522, so as to block the middle rail 3 of other said slide rail devices 10 from moving relative to the outer rail 2, achieving the effect of preventing other said slide rail devices 10 from being pulled out. Therefore, the purpose of the present utility model can be truly achieved.

[0038] The above is only an embodiment of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. 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.
