[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] See Figures 1 to 3 One embodiment of the sliding rail device 10 with locking function of this utility model is installed in a server rack (not shown) and includes an outer rail unit 1 and an inner rail unit 2. The outer rail unit 1 is fixed to the server rack, and the inner rail unit 2 is fixed to a server chassis (not shown).

[0025] The outer rail unit 1 includes an outer rail 11 and a stop member 12 disposed on the outer rail 11. The outer rail 11 has an outer first end 111 and an outer second end 112 opposite to the outer first end 111. The stop member 12 is disposed on the outer second end 112 and has a flat plate portion 121 disposed on the outer rail 11 and a stop portion 122 formed on the flat plate portion 121, the stop portion 122 being adjacent to the outer second end 112. The material or structural design of the stop member 12 is different from that of the outer rail 11, so that the strength of the stop member 12 is greater than that of the outer rail 11.

[0026] See Figures 2 to 4The inner rail unit 2 includes an inner rail 21 movably disposed on the outer rail 11, a mounting member 22 disposed on the inner rail 21, an operating member 23 movably disposed on the inner rail 21, and a locking member 24 movably disposed on the operating member 23. The inner rail 21 has an inner first end 211 and an inner second end 212 opposite to the inner first end 211 and adjacent to the outer second end 112. The mounting member 22 is disposed on the inner second end 212 and has a mounting portion 221 connecting to the inner rail 21, a protrusion 222 protruding from the mounting portion 221 and away from the inner rail 21, and a movable groove 223 formed in the protrusion 222 for the locking member 24 to movably pass through. The material or structural design of the mounting member 22 differs from that of the inner rail 21, making the strength of the mounting member 22 greater than that of the inner rail 21. The operating member 23 has a body portion 231 movably disposed between the inner rail 21 and the protrusion 222, an operating portion 232 connected to the body portion 231 and protruding from the inner second end 212, and a drive groove 233 formed in the body portion 231 and extending obliquely. The operating portion 232 is generally annular, facilitating operation by the user's fingers. The upper end of the drive groove 233 is closer to the inner second end 212 than its lower end. The locking member 24 has a head 241 and a through portion 242 connected to the head 241 and passing through the drive groove 233 and the movable groove 223. The diameter of the head 241 is larger than the diameter of the through part 242, and the head 241 is located between the inner rail 21 and the protrusion 222 of the mounting member 22, so that the locking member 24 can only move up and down in the movable groove 223 and will not move in the length direction of the through part 242, because the head 241 is engaged with the protrusion 222.

[0027] See Figure 5 and Figure 6 The operating member 23 can be operated to move the locking member 24 between a locked position and an unlocked position. In the locked position, the locking member 24 is located at the upper end of the driving groove 233. The stop portion 122 can stop the locking member 24 to prevent the inner rail 21 from moving relative to the outer rail 11 toward the outer second end 112. Figure 5 As shown, this will enable it to lock the inner rail 21. Figure 6 As shown, when the operating member 23 is operated to move away from the inner rail 21, it can drive the locking member 24 to move downward to the unlock position. In the unlock position, the locking member 24 is located at the lower end of the driving groove 233, and the inner rail 21 can move relative to the outer rail 11 towards the outer second end 112 to achieve the unlocking function.

[0028] It should be noted that in other embodiments, the stop 12 can be omitted, meaning the stop 122 is directly formed on the outer rail 11, and still serves the same stopping function. However, in this embodiment, because the strength of the stop 12 is greater than that of the outer rail 11, the stop 122 is better able to withstand the locking force of the locking member 24. Compared to embodiments where the stop 122 is directly formed on the outer rail 11, the outer rail 11 directly bears the locking force of the locking member 24. If the outer rail 11 is weaker than the stop 12, its lifespan will be shorter than in this embodiment, because the strength of the stop 122 in this embodiment is greater than that of the outer rail 11. Similarly, in other embodiments, the mounting member 22 can also be omitted, meaning the movable groove 223 is directly formed on the inner rail 21, and the structure of the inner rail 21 is adjusted to prevent the locking member 24 from moving in its length direction, allowing it to move up and down only within the movable groove 223. The mounting component 22 functions similarly to the stop component 12 described above; it is used to increase the overall structural strength of the inner rail unit 2 to improve its service life, but it is not an essential component.

[0029] In summary, the sliding rail device 10 with locking function of this utility model achieves the function of locking the inner rail 21 by having the locking member 24 located at the upper end of the driving groove 233 when in the locked position, and the stop part 122 blocking the locking member 24 to prevent the inner rail 21 from moving relative to the outer rail 11 toward the outer second end 112. Therefore, it can indeed achieve the purpose of this utility model.

[0030] 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.
