Description

Technical Field

[0001] The utility model relates to a slide rail device, in particular to a slide rail device with a stopping function. Background Art

[0002] An existing slide rail device is arranged in a server cabinet and can be used for arranging a server chassis. The slide rail device includes an outer rail, a middle rail movably arranged on the outer rail, an inner rail movably arranged on the middle rail, a pair of stoppers arranged between the outer rail and the middle rail and located at one end of the outer rail, and a pair of sliding assist members arranged between the outer rail and the middle rail. The inner rail is used for arranging the server chassis. When the server chassis needs to be maintained, the server chassis needs to be pulled out so that the slide rail device is in an extended state, that is, the inner rail extends relative to the middle rail, and the middle rail extends relative to the outer rail. In the extended state, the sliding assist members will finally abut against the stoppers as the middle rail moves, preventing the middle rail from disengaging from the outer rail during the extension process. After long-term use, the sliding assist members may be deformed, bent or even damaged due to repeated impacts against the stoppers. Therefore, there is still room for improvement.

[0031] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0032] Refer to Figures 1 to 3 , the first embodiment of the slide rail device 10 of the present utility model is applicable to be installed in a server cabinet (not shown in the figure) and can be used for setting a server chassis (not shown in the figure). The slide rail device 10 includes a first slide rail unit 1, a second slide rail unit 2, and a third slide rail 3.

[0033] Refer to Figures 2 to 4 , the first slide rail unit 1 includes a first slide rail 11. The first slide rail 11 includes a first bottom plate 111 and two first side walls 112 formed on the upper and lower sides of the first bottom plate 111. The first bottom plate 111 has a first end 111a, a second end 111b opposite to the first end 111a, and a sliding surface 111c facing the second slide rail unit 2. The sliding surface 111c forms a stop block 12. The first slide rail unit 1 further includes two ball bars 13 that can be movably arranged on the first side walls 112 respectively and two stop support members 14 that are fixedly arranged on the first side walls 112 respectively and are adjacent to the first end 111a.

[0034] Refer to Figure 3 ,Figures 5 to 7 The second slide rail unit 2 includes a second slide rail 21 movably disposed on the first slide rail 11, a reinforcing member 22 disposed on the second slide rail 21, and two pushing and supporting members 23 respectively disposed on the upper and lower sides of the second slide rail 21. The second slide rail 21 has a first surface 211 facing the sliding surface 111c and a second surface 212 opposite to the first surface 211 and facing the third slide rail 3. The reinforcing member 22 is made of a metal material with a relatively high hardness and is generally in the shape of a rectangular plate (strip). It is disposed on the first surface 211 and has a main body portion 221 extending along the second slide rail 21 and a stop portion 222 protruding from the main body portion 221. The stop portion 222 can be abutted against the stop block 12. The third slide rail 3 is movably disposed on the second slide rail 21 and can be used for setting a server chassis (not shown).

[0035] Refer to Figure 3 、 Figures 6 to 8 The second slide rail 21 can move relative to the first slide rail 11 between an initial position and an extended position. In the initial position, the main body portion 221 of the reinforcing member 22 does not protrude from the first slide rail 11 and the stop portion 222 is spaced from the stop block 12, and the pushing and supporting members 23 are adjacent to the second end 111b and are spaced from the ball strip 13. When the second slide rail 21 moves relative to the first slide rail 11 toward the first end 111a, the pushing and supporting members 23 can drive the ball strip 13 to move until reaching the extended position. In the extended position, a part of the main body portion 221 protrudes from the first slide rail 11 and the stop portion 222 is abutted against the stop block 12, and the ball strip 13 abuts against the stop and supporting member 14 to prevent the second slide rail 21 from moving out of the first slide rail 11 and separating from the first slide rail 11. By disposing the reinforcing member 22 on the second slide rail 21, the overall structural strength of the second slide rail unit 2 can be increased, and the risk of deformation, bending or even damage of the second slide rail 21 can be reduced. Further, by abutting the stop portion 222 against the stop block 12, when the second slide rail 21 is pulled out relative to the first slide rail 11 by an external force in the extended state, the stop portion 222 can share the abutting reaction force between the ball strip 13 and the stop and supporting member 14, and the risk of deformation or damage of the ball strip 13 can be reduced.

[0036] Refer to Figures 9 to 12, the second embodiment of the sliding rail device 10 of the present utility model is similar to the first embodiment, except that the reinforcing member 22' is different. The reinforcing member 22' has three body portions 221' arranged at intervals, and a stopping portion 222' is formed on one of the body portions 221'. The gaps between the body portions 221' are inclined straight lines, so that the middle body portion 221' is generally trapezoidal in shape, and the body portions 221' can be generally spliced into a rectangular plate shape, but this is not limiting. Similarly, in this unfolded position, a part of the middle body portion 221' protrudes from the first sliding rail 11 and the stopping portion 222 abuts against the stopping block 12, and the ball strip 13 (see Figure 8 ) abuts against the stopping support member 14 to prevent the second sliding rail 21 from moving out of the first sliding rail 11 and separating from the first sliding rail 11. By providing the reinforcing member 22' on the second sliding rail 21, the overall structural strength of the second sliding rail unit 2 can be increased, and the risk of deformation, bending or even damage of the second sliding rail 21 can be reduced. Furthermore, by the stopping portion 222' abutting against the stopping block 12, when the second sliding rail 21 is pulled out relative to the first sliding rail 11 by an external force in the unfolded state, the stopping portion 222' can share the abutting reaction force between the ball strip 13 and the stopping support member 14, reducing the risk of deformation or damage of the ball strip 13.

[0037] It should be noted that the present utility model is not limited to the foregoing embodiments and does not necessarily include the first sliding rail unit 1, the second sliding rail unit 2 and the third sliding rail 3. In other embodiments, it may only include the first sliding rail unit 1 and the second sliding rail unit 2 and does not include the third sliding rail 3, and a server chassis (not shown in the figure) is provided on the second sliding rail 21. In other embodiments, the reinforcing member may have a plurality of body portions arranged at intervals along the second sliding rail, and is not limited to the implementation manner of the three body portions described above.

[0038] In summary, the sliding rail device 10 of the present utility model can limit the length of the second sliding rail 21 extending relative to the first sliding rail 11 by the stopping portions 222, 222' of the reinforcing members 22, 22' abutting against the stopping block 12. At the same time, the body portions 221, 221' of the reinforcing members 22, 22' can increase the overall structural strength of the second sliding rail unit 2 and reduce the risk of deformation, bending or even damage of the second sliding rail 21. Therefore, the object of the present utility model can be truly achieved.

[0039] 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 fall within the scope of the present utility model.
