[0043] Referring to Figures 5 to 7 and Figure 11 The unlocking member 24 has a ring-shaped operation portion 241, a movable portion 242 connected to the operation portion 241 and movably arranged on the first surface 211 along the horizontal direction D1, an unlocking slot 243 formed through the movable portion 242, and a hook portion 244 connected to the movable portion 242. The protruding column 231a penetrates the unlocking slot 243 and abuts against the movable portion 242. The unlocking slot 243 has an inclined segment 243a and an unlocking segment 243b connected to the inclined segment 243a, the width of the inclined segment 243a in an up-down direction D2 perpendicular to the horizontal direction D1 gradually decreases in a direction approaching the unlocking segment 243b, and the width of the unlocking segment 243b in the up-down direction D2 is greater than the width of one end of the inclined segment 243a adjacent to the unlocking segment 243b. The movable portion 242 has an inclined surface 242a located below the inclined segment 243a, and a clamping point 242b located between the inclined segment 243a and the unlocking segment 243b. The unlocking elastic member 29 connects the hook portion 244 and the unlocking clamping hook 216.

[0044] Referring to Figures 5 to 7 The clamping member 25 has a substantially L-shaped body portion 251 pivotally arranged on the first surface 211, a clamping portion 252 extending away from the second support plate 21 from one end of the body portion 251, an abutting portion 253 bent and extending from the other end of the body portion 251 and penetrating the second support plate 21, and a clamping hook portion 254 connected to the body portion 251 and adjacent to the abutting portion 253. The clamping portion 252 can be clamped on the middle clamping hook 222a. The clamping elastic member 20 connects the clamping hook portion 254 and the clamping clamping hook 217.

[0045] Referring to Figures 6 to 8 , the glide aid 26 is arranged on the second surface 212 and abuts against the side wall 112 above, so that the second sliding rail module 2 can slide more smoothly relative to the first support plate 11. Specifically, the glide aid 26 is a roller, but is not limited thereto, and the number thereof is also not limited to three, but can be multiple.

[0046] Referring to Figures 11 to 14 , the unlocking member 24 can be operated to move between a locked position and an unlocked position. In the locked position, the protruding column 231a of the locking member 23 abuts against the movable portion 242 and is located at an end of the inclined section 243a away from the unlocking section 243b and a lower end of the movable groove 213, and the engagement section 233b extends into the first locking hole 112a, so that the second support plate 21 cannot move relative to the first support plate 11. The operation portion 241 can be operated to move away from the second support plate 21 in the horizontal direction D1, so as to drive the protruding column 231a to move upward along the inclined surface 242a and the movable groove 213, and finally enter the unlocking section 243b and be stopped by the catch point 242b to reach the unlocked position. In the unlocked position, the engagement section 233b is disengaged 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.

[0047] Referring to Figure 15 and Figure 16When the second support plate 21 continuously moves towards the second end 111b, the surrounding wall part 232 of the locking member 23 will abut against the protruding part 113c and be pushed upward by the protruding part 113c to make the protruding column 231a move upward and separate from the clamping point 242b, at this time the operation part 241 of the unlocking member 24 is pulled in the horizontal direction D1 towards the second support plate 21 by the elastic restoring force of the unlocking elastic member 29 to return to the locking position, at this time the protruding column 231a of the locking member 23 is located on the upper end of the inclined section 243a of the unlocking slot 243, as shown in Figure 16 Fig. 6. Figure 5 Figure 17 After the surrounding wall part 232 passes the protruding part 113c, the elastic restoring force of the locking elastic member 235 pushes the locking member 23 to move downward, so that the clamping section 233b of the clamping block part 233 extends into the second locking hole 112b, and the second support plate 21 is positioned relative to the first support plate 11, as shown in Figure 17 Fig. 7.

[0048] Referring to Figure 5 , Figure 18 Figure 19 , during the movement of the second support plate 21 relative to the first support plate 11, specifically before the second support plate 21 moves to the second end 111b, the abutting part 253 will abut against the blocking point 113b1 to drive the clamping part 252 to pivot upward to release the clamping relationship between the clamping part 252 and the middle clamping hook 222a, and the second middle rail 222 can extend relative to the second outer rail 221.

[0049] In summary, the slide rail system 10 of the present application can make the locking member 23 extend into the first locking hole 112a, when the user wants to install a case to the first slide rail device 12, the second slide rail module 2 cannot move relative to the first support plate 11, which can increase the safety during installation, and after the installation is completed, the unlocking member 24 drives the locking member 23 to disengage from the first locking hole 112a, so that the second support plate 21 can move relative to the first support plate 11, which can increase the safety while retaining the activity convenience between the first slide rail module 1 and the second slide rail module 2, so the purpose of the present application can be achieved.

[0050] The above is only an embodiment of the present application, which cannot limit the scope of the present application, any simple equivalent changes and modifications made according to the claims and the content of the specification of the present application are still within the scope of the present application.​​
