Description

Technical Field

[0001] This utility model relates to a slide rail device, and more particularly to a slide rail device with a support member. Background Technology

[0002] Existing slide rail devices, installed in a server rack and designed to accommodate a server chassis, include an outer rail, a middle rail movably mounted on the outer rail, and an inner rail movably mounted on the middle rail, with the inner rail housing the server chassis. When the server chassis requires maintenance, it needs to be pulled out, placing the slide rail device in an extended position, with the inner rail extending relative to the middle rail, and the middle rail extending relative to the outer rail. In this extended position, the server chassis exerts torque on the middle and inner rails, which may lead to deformation, bending, or even damage over time. Current solutions use plate-like reinforcing members to strengthen the slide rail structure. While these can increase the load-bearing capacity of the middle or inner rail when the slide rail device is extended, the plate-like reinforcing members do not abut against the sidewalls of the middle or inner rails, limiting their load-distribution effectiveness and leaving room for improvement. Utility Model Content

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

[0004] The slide rail device of this utility model includes a first slide rail having a first base plate and two first side walls extending laterally from the upper and lower sides of the first base plate; a second slide rail being movably disposed on the first slide rail and having a second base plate and second side walls extending laterally from the upper and lower sides of the second base plate; and a support member being disposed on the second slide rail and abutting against the second side walls.

[0005] In some embodiments, the support includes a base plate fixedly disposed on the second base plate and two side plates extending laterally from the upper and lower sides of the base plate and respectively abutting against the second side wall.

[0006] In some embodiments, the support member also includes a plurality of reinforcing ribs disposed between the base plate and the side plate.

[0007] In some embodiments, the second slide rail includes a first portion movably disposed on the first slide rail and a second portion fixedly connected to the first portion. The first portion has a second base plate and a second side wall. The second portion has a second base plate and a second side wall. The support member is fixedly disposed on the second base plate of the first portion. The second base plate of the first portion is fixedly connected to the second base plate of the second portion. The extension direction of the second side wall of the first portion is opposite to the extension direction of the second side wall of the second portion.

[0008] This utility model has at least the following effects: by setting the support member on the second slide rail and abutting against the second side wall, the overall structural strength of the second slide rail can be improved, the resistance to deformation can be increased, the load-bearing capacity can be enhanced, and the effect of distributing load can be improved.

[0025] See Figure 1 and Figure 2 The first embodiment of the slide rail device 10 of this utility model is suitable for installation in a server rack (not shown) and can be installed in a server chassis (not shown). The slide rail device 10 includes an outer rail 1, a middle rail 2, an inner rail 3 and a support member 4.

[0026] See Figures 3 to 5 The outer rail 1 has an outer base plate 11 and two outer side walls 12 extending laterally from the upper and lower sides of the outer base plate 11. The middle rail 2 is movably disposed on the outer rail 1 and has a middle base plate 21 and two middle side walls 22 extending laterally from the upper and lower sides of the middle base plate 21. The inner rail 3 is movably disposed on the middle rail 2 and can be used for the server chassis (not shown), and has an inner base plate 31 and two inner side walls 32 extending laterally from the upper and lower sides of the inner base plate 31. The support member 4 can be fixedly disposed on the inner rail 3 by means of screws or rivets and abuts against the inner side walls 32, and includes a base plate 41 fixedly disposed on the inner base plate 31 and two side plates 42 extending laterally from the upper and lower sides of the base plate 41 and respectively abutting against the inner side walls 32. It should be noted that, in this embodiment, the substrate 41 is attached to the inner bottom plate 31, but this is not a limitation. In other embodiments, the substrate 41 may be spaced apart from the inner bottom plate 31, as long as the side plates 42 respectively abut against the inner sidewalls 32. The support member 4 is not limited to the U-shaped form in this embodiment; in other embodiments, it may also be I-shaped, meaning that the side plates 42 protrude from the substrate 41 on both sides.

[0027] The slide rail device 10 can switch between an initial state and an extended state. In the initial state, the outer rail 1, the middle rail 2, and the inner rail 3 overlap each other. In the extended state, the middle rail 2 extends relative to the outer rail 1, and the inner rail 3 extends relative to the middle rail 2. At this time, the support member 4 is located at the intersection of the middle rail 2 and the inner rail 3. By setting the support member 4 on the inner bottom plate 31 of the inner rail 3 and abutting against the inner side wall 32, the support member 4 can share the torque generated by the server chassis (not shown) on the middle rail 2 and the inner rail 3, and can improve the overall structural strength of the inner rail 3, increase its resistance to deformation, enhance its load-bearing capacity, and improve the effect of load distribution.

[0028] It should be noted that in this embodiment, the middle rail 2 is the first slide rail, the inner rail 3 is the second slide rail, and the inner side wall 32 is the second side wall; however, this is not a limitation. In other embodiments, the first slide rail can be the outer rail 1, and the second slide rail can be the middle rail 2.

[0029] See Figure 6 and Figure 7 The second embodiment of the slide rail device 10' of this utility model is suitable for installation in a server rack (not shown) and can be installed in a server chassis (not shown). The slide rail device 10' includes an outer rail 1, a middle rail 2', an inner rail 3 and a support member 4.

[0030] See Figure 8 and Figure 9The outer rail 1 has an outer base plate 11 and two outer side walls 12 extending laterally from the upper and lower sides of the outer base plate 11. The middle rail 2' is movably disposed on the outer rail 1 and includes a middle outer portion 2a movably disposed on the outer rail 1 and a middle inner portion 2b fixedly connected to the middle outer portion 2a. The middle outer portion 2a has a middle outer base plate 2a1 and two middle outer side walls 2a2 extending laterally from the upper and lower sides of the middle outer base plate 2a1. The middle inner portion 2b has a middle inner base plate 2b1 and two middle inner side walls 2b2 extending laterally from the upper and lower sides of the middle inner base plate 2b1. The middle outer base plate 2a1 of the middle outer portion 2a is fixedly connected to the middle inner base plate 2b1 of the middle inner portion 2b. The extending direction of the middle outer side walls 2a2 of the middle outer portion 2a is opposite to the extending direction of the middle inner side walls 2b2 of the middle inner portion 2b. The width of the inner bottom plate 2b1 is greater than the width of the outer bottom plate 2a1. The design of the middle rail 2' in this embodiment is equivalent to combining two slide rails together, resulting in high structural strength. The inner rail 3 is movably disposed on the middle rail 2', allowing the server chassis (not shown) to be installed, and has an inner bottom plate 31 and two inner sidewalls 32 extending laterally from the upper and lower sides of the inner bottom plate 31. The support member 4 is the same as in the first embodiment, and can be fixedly disposed on the outer middle portion 2a of the middle rail 2' by means of screws or rivets and abuts against the outer middle wall 2a2. Similarly, in this embodiment, the base plate 41 is attached to the outer middle bottom plate 2a1, but this is not a limitation. In other embodiments, the base plate 41 can also be spaced apart from the outer middle bottom plate 2a1, as long as the side plates 42 abut against the outer middle wall 2a2 respectively. It should be noted that in this embodiment, the outer rail 1 is the first slide rail, the middle rail 2' is the second slide rail, the outer middle part 2a is the first part, the inner middle part 2b is the second part, the outer middle bottom plate 2a1 and the inner middle bottom plate 2b1 are the second bottom plate, and the outer middle side wall 2a2 and the inner middle side wall 2b2 are the second side wall.

[0031] The slide rail device 10' can switch between an initial state and an extended state. In the initial state, the outer rail 1, the middle rail 2', and the inner rail 3 overlap each other. In the extended state, the middle rail 2' extends relative to the outer rail 1, and the inner rail 3 extends relative to the middle rail 2'. At this time, the support member 4 is located at the intersection of the outer rail 1 and the middle rail 2'. By setting the support member 4 on the middle outer base plate 2a1 of the middle rail 2' and abutting against the middle outer outer wall 2a2, the support member 4 can share the torque generated by the server chassis (not shown) on the middle rail 2' and the inner rail 3, and can improve the overall structural strength of the middle rail 2', increase its resistance to deformation, enhance its load-bearing capacity, and improve the effect of load distribution.

[0032] See Figure 10 and Figure 11In other embodiments, the support member 4' also has a variation. The support member 4' can be fixedly disposed on the middle rail 2' and abut against the middle outer wall 2a2 by means of screws or rivets, and includes a base plate 41 fixedly disposed on the middle outer bottom plate 2a1, two side plates 42 extending laterally from the upper and lower sides of the base plate 41 and respectively abutting against the middle outer wall 2a2, and a plurality of generally block-shaped reinforcing ribs 43 disposed between the base plate 41 and the side plates 42. The reinforcing ribs 43 are not limited to the form of this embodiment. In other embodiments, the reinforcing ribs 43 can also be strip-shaped and disposed between the base plate 41 and the side plates 42, with both ends respectively connected to the side plates 42.

[0033] In summary, the slide rail devices 10 and 10' of this utility model, by means of the support members 4 and 4', are set on the second slide rail and abut against the second side wall, which can improve the overall structural strength of the second slide rail, increase its resistance to deformation and its load-bearing capacity, and improve the effect of distributing load. Therefore, it can indeed achieve the purpose of this utility model.

Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
