Description

Technical Field

[0001] This utility model relates to a slide rail system, and more particularly to a slide rail system with synchronous movement function. Background Technology

[0002] An existing slide rail system includes a first slide rail module and a second slide rail module movably disposed on the first slide rail module. The second slide rail module has a second outer rail, a second middle rail, and a second inner rail. The second slide rail module slides on the first slide rail module. Some users require the second slide rail module to slide to the front of the first slide rail module before separating the second outer rail and the second middle rail. This is because the second outer rail, second middle rail, and second inner rail can support the server chassis together, maximizing the supporting force and improving stability. However, since the existing slide rail system is designed so that the second middle rail slides relative to the second outer rail from the beginning, it cannot meet the above requirements. Therefore, there is still room for improvement. Utility Model Content

[0003] The purpose of this invention is to provide a slide rail system that can solve at least one of the above-mentioned problems.

[0004] This utility model slide rail system includes a first slide rail module, comprising a first support plate and a first slide rail device disposed on the first support plate; and a second slide rail module, comprising a second support plate movably disposed on the first support plate, a second slide rail device disposed on the second support plate, a linkage movably disposed on the second support plate, and a locking member pivotally disposed on the second slide rail device and connected to the linkage member. The second slide rail device has a second outer rail disposed on the second support plate for pivotal mounting by the locking member and a second middle rail movably disposed on the second outer rail. The second middle rail has a central hook capable of locking onto the locking member. When the second middle rail moves relative to the second outer rail, it can drive the second outer rail and the second support plate to move synchronously.

[0005] In some embodiments, the locking member has a body portion pivotally mounted on the second outer rail, a locking portion protruding from the body portion in a direction away from the second outer rail, and a connecting portion connecting the body portion and the linkage member.

[0006] In some embodiments, the linkage has a rod portion that is movably disposed on the second support plate and a linkage tenon that connects the rod portion and passes through the linkage portion.

[0007] In some embodiments, the first support plate has a slot, and the linkage also has a connecting part that connects to the rod and a positioning tenon that passes through the connecting part. The slot allows the positioning tenon to fall into it, so that the second slide rail module is positioned relative to the first support plate and drives the locking member to pivot, thereby releasing the locking relationship between the locking part and the middle hook.

[0008] In some embodiments, the first support plate further has a bottom wall, two side walls formed on the upper and lower sides of the bottom wall, and an upper extension wall formed on the upper side wall, the upper extension wall forming the slot.

[0009] In some embodiments, the second slide rail device further has a second inner rail movably disposed on the second middle rail, and the linkage member further has an abutting protrusion protruding from the rod portion in a direction away from the second outer rail, the second inner rail being able to push against the abutting protrusion to move the linkage member upward, thereby disengaging the positioning latch from the slot.

[0010] In some embodiments, the second inner rail has a pushing ramp, and the abutting protrusion forms a ramp corresponding to the pushing ramp, the pushing ramp abutting the ramp to move the linkage upward.

[0011] This utility model has at least the following effects: the middle hook can be engaged with the locking member, and when the second middle rail moves relative to the second outer rail, it can drive the second outer rail and the second support plate to move synchronously, so that the synchronous movement effect can be achieved without any further operation.

[0029] See Figure 1 and Figure 2 One embodiment of the slide rail system 10 of this utility model includes a first slide rail module 1 and a second slide rail module 2 movably disposed on the first slide rail module 1.

[0030] See Figures 3 to 5 The first slide rail module 1 includes a first support plate 11 extending along a horizontal direction D1 and a first slide rail device 12 disposed on the first support plate 11. The first support plate 11 has a bottom wall 111, two side walls 112 formed on the upper and lower sides of the bottom wall 111, and an upper extension wall 113 formed on the upper side wall 112. The bottom wall 111 has a first end 111a and a second end 111b opposite to the first end 111a. The upper extension wall 113 has a slot 113a ( Figure 8 ).

[0031] See Figures 4 to 6 The second slide rail module 2 includes a second support plate 21 movably disposed on the first support plate 11, a second slide rail device 22 disposed on the second support plate 21, a linkage 23 movably disposed on the second support plate 21 along a vertical direction D2, a locking member 24 pivotally disposed on the second slide rail device 22 and connected to the linkage 23, and an elastic member 25 disposed between the second slide rail device 22 and the linkage 23. The second support plate 21 has a first surface 211 for the second slide rail device 22 to be disposed on, and a second surface 212 opposite to the first surface 211. The second slide rail device 22 has a second outer rail 221 disposed on the first surface 211, a second middle rail 222 movably disposed on the second outer rail 221, and a second inner rail 223 movably disposed on the second middle rail 222. The second middle rail 222 has a central hook 222a. The second inner rail 223 has a pushing inclined surface 223a.

[0032] The locking member 24 has a body portion 241 pivotally mounted on the second outer rail 221, a locking portion 242 protruding from the body portion 241 in a direction away from the second outer rail 221, and a connecting portion 243 connecting the body portion 241 and the connecting member 23. The locking portion 242 can lock onto the central hook 222a. The connecting member 23 has a rod portion 231 movably disposed on the second support plate 21 along the vertical direction D2, a connecting portion 232 connecting the rod portion 231, a positioning tenon 233 passing through the connecting portion 232, an abutting protrusion 234 protruding from the rod portion 231 in a direction away from the second outer rail 221, and a connecting tenon 235 connecting the rod portion 231 and passing through the connecting portion 243. An elastic member 25 is disposed between the abutting protrusion 234 and the second outer rail 221.

[0033] See Figure 1 , Figures 7 to 9 The second inner rail 223 can accommodate a server chassis (not shown). When a user wants to pull out the server chassis, they will first pull the second inner rail 223 and the second middle rail 222 toward the second end 111b (see figure). Figure 2 The second slide rail module 2 moves in the direction of the first support plate 11, and is engaged with the middle hook 222a by the locking part 242. When the second middle rail 222 and the second inner rail 223 move relative to the second outer rail 221, the second outer rail 221 and the second support plate 21 can move synchronously. When the second support plate 21 moves relative to the first support plate 11 until the positioning tenon 233 is above the slot 113a, the elastic restoring force generated by the elastic member 25 in the stretched state will drive the linkage member 23 to move downward, and the positioning tenon 233 will fall into the slot 113a, so that the second slide rail module 2 is positioned relative to the first support plate 11. And because the positioning tenon 233 falls into the slot 113a, the linkage member 23 moves downward and drives the locking member 24 to pivot, releasing the locking relationship between the locking part 242 and the middle hook 222a. Figure 9 As shown. When the locking relationship is released, the second middle rail 222 and the second inner rail 223 can extend relative to the second outer rail 221, as... Figure 10 As shown.

[0034] See Figure 11 and Figure 12 When the user attempts to push the server chassis (not shown) back, it will cause the second inner rail 223 to move towards the first end 111a (see figure). Figure 2The second inner rail 223 moves in the direction of the first end 111a. The pushing slope 223a of the second inner rail 223 abuts against the slope 234a of the abutting protrusion 234 of the linkage 23. The linkage 23 then moves upward, causing the positioning tenon 233 to disengage from the slot 113a and the locking member 24 to pivot upward, allowing the locking part 242 to re-lock onto the middle hook 222a. The second support plate 21 moves towards the first end 111a (see...). Figure 2 When it moves in the direction of ), it will simultaneously drive the second middle rail 222 and the second inner rail 223 to move and reset.

[0035] In summary, the slide rail system 10 of this utility model can be engaged with the locking member 24 by means of the middle hook 222a. When the second middle rail 222 moves relative to the second outer rail 221, it can drive the second outer rail 221 and the second support plate 21 to move synchronously. The synchronous movement effect can be achieved without any further operation, so it can indeed achieve the purpose of this utility model.

[0036] The above description is merely an embodiment of this utility model and should not be construed as limiting the scope of this utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of this utility model shall still fall within the scope of this utility model.
