Description

Technical Field

[0001] The utility model relates to a slide rail system, in particular to a slide rail system with a relative movement function. Background Art

[0002] An existing slide rail system is applicable to a server cabinet and can be used for installing a server chassis. When a user wants to replace or maintain the server chassis, the server chassis can be easily pulled out through the slide rail system. However, when the lengths of the server cabinet and the slide rail system are much longer than the length of the server chassis, spatial waste will inevitably occur. An existing improvement method is to add another slide rail device in the slide rail system, the length of which is slightly less than the length difference between the server cabinet and the server chassis, and enable one of the slide rail devices to move relative to the other slide rail device, so that additional mechanisms can be carried on the added slide rail device. However, if the added slide rail device is directly arranged on the original slide rail device, it may press the original slide rail device and cause it to deform during movement, thereby resulting in a situation of unsmooth movement. Therefore, there is still room for improvement. Summary of the Utility Model

[0003] One object of the utility model is to provide a slide rail system that can solve at least one of the above problems.

[0004] The slide rail system of the utility model includes a first slide rail module, which includes a first support plate and a first slide rail device arranged on the first support plate; and a second slide rail module, which includes a second support plate movably arranged on the first support plate and a second slide rail device arranged on the second support plate.

[0005] In some embodiments, the first support plate 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, and the second support plate can move along the upper extension wall.

[0006] In some embodiments, the second support plate has a first surface for arranging the second slide rail device and a second surface opposite to the first surface, and the second slide rail module further includes a plurality of sliding assistance members arranged on the second surface and abutting against the upper side wall.

[0007] In some embodiments, the second slide rail module further includes a plurality of upper limit members arranged on the second support plate and located on both side surfaces of the upper extension wall.

[0008] In some embodiments, the second support plate has a plurality of L-shaped limiting pieces formed on the second surface, each of the upper limit members has a mounting portion arranged on the first surface and a limiting portion connecting the mounting portion and passing through the second support plate and abutting against the corresponding limiting piece, and the limiting portion is in an inverted U shape and is located on both side surfaces of the upper extension wall.

[0009] In some embodiments, the first support plate further has a lower extension wall formed on the lower side wall below, and the second slide rail module further includes a plurality of lower limit members disposed on the second support plate and located on both side surfaces of the lower extension wall.

[0010] In some embodiments, the bottom wall has a first end and a second end opposite to the first end, and the first slide rail module further includes a stopper disposed at the first end.

[0011] In some embodiments, the lower extension wall has a stopper portion protruding downward at the second end.

[0012] The utility model at least has the following effects: Since the second support plate of the second slide rail module is movably disposed on the first support plate, the weight of the second slide rail module will be applied to the first support plate rather than the first slide rail device, which can reduce the risk of deformation and damage of the first slide rail device.

The second support plate 21 has a first surface 211 for the second slide rail device 22 to be disposed on, a second surface 212 opposite to the first surface 211, a moving slot 213 extending along the up and down direction D2, two mounting slots 214 extending along the up and down direction D2 and located on both sides of the moving slot 213, two sleeve locking blocks 215 formed on the second surface 212, an unlocking hook 216 formed on the first surface 211, a locking hook 217 formed on the first surface 211, and two L-shaped limiting pieces 218 formed on the second surface 212. The aforementioned stopping portion 114a can be used to stop the second support plate 21 to prevent the second support plate 21 from detaching from the first support plate 11 at the second end 111b.

[0040] 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 in the second outer rail 221, and a second inner rail 223 movably disposed in the second middle rail 222. The second middle rail 222 has a middle locking hook 222a.

[0041] Refer to Figure 6 , Figures 8 to 10, the locking member 23 is disposed on the second support plate 21 by a positioning member 236, and includes a flat plate portion 231 movably disposed on the second surface 212, a surrounding wall portion 232 formed on the flat plate portion 231 and extending away from the second surface 212 in a substantially U shape, a clamping block portion 233 formed on the surrounding wall portion 232 and capable of extending into the first locking hole 112a, and two sleeve portions 234 formed on both sides of the surrounding wall portion 232. The flat plate portion 231 has a convex column 231a passing through the moving slot 213 and abutting against the unlocking member 24, and two convex points 231b capable of correspondingly accommodating in the mounting slots 214. The clamping block portion 233 has an abutting section 233a capable of abutting against the side wall 112 and a clamping section 233b extending downward from the abutting section 233a and capable of extending into the first locking hole 112a. Each of the sleeve portions 234 has a receiving slot 234a, and the receiving slots 234a can respectively allow the sleeve clamping blocks 215 to extend into the upper ends and can accommodate two locking elastic members 235. One end of each locking elastic member 235 abuts against the corresponding sleeve clamping block 215, and the other end abuts against the bottom of the sleeve portion 234.

[0042] Refer to Figures 5 to 7 and Figure 11 , the unlocking member 24 has an annular operation portion 241, a moving portion 242 connected to the operation portion 241 and movably disposed on the first surface 211 along the horizontal direction D1, an unlocking slot 243 formed through the moving portion 242, and a hook portion 244 connected to the moving portion 242. The convex column 231a passes through the unlocking slot 243 and abuts against the moving portion 242. The unlocking slot 243 has an inclined section 243a and an unlocking section 243b connected to the inclined section 243a. The width of the inclined section 243a in the up and down direction D2 perpendicular to the horizontal direction D1 gradually decreases toward the direction approaching the unlocking section 243b, and the width of the unlocking section 243b in the up and down direction D2 is greater than the width of one end of the inclined section 243a adjacent to the unlocking section 243b. The moving portion 242 has an inclined surface 242a located below the inclined section 243a and a clamping point 242b located between the inclined section 243a and the unlocking section 243b. The unlocking elastic member 29 connects the hook portion 244 and the unlocking catch 216.

[0043] Refer to Figures 5 to 7 , the locking member 25 has a substantially L-shaped body portion 251 pivotally disposed on the first surface 211, a locking portion 252 extending from one end of the body portion 251 away from the second support plate 21, an abutting portion 253 extending and bending from the other end of the body portion 251 and passing through the second support plate 21, and a catch portion 254 connected to the body portion 251 and adjacent to the abutting portion 253. The locking portion 252 can be locked to the middle catch 222a. The locking elastic member 20 connects the catch portion 254 and the locking catch 217.

[0044] Refer to Figures 6 to 8 , the sliding assist member 26 is disposed on the second surface 212 and abuts against the upper side wall 112, which can enable the second slide rail module 2 to slide relative to the first support plate 11 more smoothly. Specifically, the sliding assist member 26 is a roller, but is not limited thereto, and its quantity is not limited to three, as long as there are multiple ones. The upper limit member 27 is disposed on the second support plate 21 and on both side surfaces of the upper extension wall 113. Each upper limit member 27 has a mounting portion 271 disposed on the first surface 211 and a limiting portion 272 connecting the mounting portion 271 and passing through the second support plate 21 and abutting against the corresponding limiting piece 218. The limiting portion 272 is in an inverted U shape and is located on both side surfaces of the upper extension wall 113, and can allow the upper extension wall 113 to extend therein and be limited. The lower limit member 28 is disposed on the second support plate 21 and on both side surfaces of the lower extension wall 114, and can allow the lower extension wall 114 to extend therein and be limited. By the arrangement of the upper limit member 27 and the lower limit member 28, the frictional force of the second slide rail module 2 sliding relative to the first support plate 11 can be reduced, and the second slide rail module 2 can also slide relative to the first support plate 11 more smoothly. It should be noted that the quantities of the sliding assist member 26, the upper limit member 27, and the lower limit member 28 are not limited to this embodiment, and may be other quantities in other embodiments, as long as there are multiple ones.

[0045] Refer to Figures 11 to 14 , the unlocking member 24 can be operated to move between a locked position and an unlocked position. When in the locked position, the convex column 231a of the locking member 23 abuts against the movable portion 242 and is located at one end of the inclined section 243a away from the unlocking section 243b and the lower end of the movable groove 213, and the engaging section 233b extends into the first locking hole 112a. At this time, the second support plate 21 cannot move relative to the first support plate 11. The operating portion 241 can be operated to move away from the second support plate 21 in the horizontal direction D1, so as to drive the convex column 231a to move upward along the inclined surface 242a and the movable groove 213, and finally enter the unlocking section 243b and be blocked by the locking point 242b to reach the unlocked position. When in the unlocked position, the engaging section 233b disengages from the first locking hole 112a, so that the second support plate 21 can move relative to the first support plate 11. At this time, the unlocking elastic member 29 is in a stretched state, and the locking elastic member 235 (see Figure 6 ) is in a compressed state to accumulate elastic restoring force.

[0046] Refer to Figure 15 and Figure 16, when the second support plate 21 continuously moves towards the second end 111b, the surrounding wall portion 232 of the locking member 23 will abut against the protruding portion 113c and be pushed upward by the protruding portion 113c, causing the convex post 231a to move upward and separate from the locking point 242b. At this time, the operating portion 241 of the unlocking member 24 is pulled by the elastic restoring force of the unlocking elastic member 29 and moves towards the second support plate 21 in the horizontal direction D1 to return to the locking position. At this time, the convex post 231a of the locking member 23 is still located at the upper end of the inclined section 243a of the unlocking groove 243, as Figure 16 shown. Then refer to Figure 5 and Figure 17 . After the surrounding wall portion 232 passes over the protruding portion 113c, the elastic restoring force of the locking elastic member 235 pushes the locking member 23 downward, causing the engaging section 233b of the engaging block portion 233 to extend into the second locking hole 112b, positioning the second support plate 21 relative to the first support plate 11, as Figure 17 shown.

[0047] Refer to Figure 5 , Figure 18 and Figure 19 . During the process of the second support plate 21 moving relative to the first support plate 11, specifically, before the second support plate 21 moves to the second end 111b, the abutting portion 253 will abut against the stopping point 113b1 and drive the locking portion 252 to pivot upward to release the locking relationship between the locking portion 252 and the middle locking hook 222a, and the second middle rail 222 can extend relative to the second outer rail 221.

[0048] In summary, in the sliding rail system 10 of the present invention, the second support plate 21 of the second sliding rail module 2 is movably disposed on the first support plate 11, and the weight of the second sliding rail module 2 will be applied to the first support plate 11 instead of the first sliding rail device 12, which can reduce the risk of deformation and damage of the first sliding rail device 12. Therefore, the object of the present invention can be truly achieved.

[0049] The above is only an embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still belong to the scope of the present invention.
