Description

Technical Field

[0001] This utility model relates to a slide rail for preventing deformation under stress, particularly a slide rail for a cabinet adapted to an industrial server, which is provided on one side of the slide rail by a support member or support accessory to enhance the structural strength of the slide rail. Background Technology

[0002] In existing industrial servo slide rails, the slide rail typically has a first rail (e.g., outer frame), a second rail (e.g., middle frame), a third rail (e.g., inner frame), a support member, and another support member. Conventional installation methods often involve the second rail slidably connected to the first rail, and the third rail slidably connected to the second rail. The second rail extends the sliding travel of the third rail relative to the first rail. The side of the first rail furthest from the second rail is mounted on the servo rack, and the side of the third rail furthest from the second rail is mounted on the servo chassis. The first rail extends and bends outward to form a first sidewall. The first rail has a second sidewall that extends and bends outwards, while the second rail has a third sidewall that extends and bends outwards. A support member is installed at the rear end of the first rail, abutting against both the first and second sidewalls. Another support member is installed at the front end of the second rail, positioned in a first mounting groove penetrating the second sidewall. This support member abuts against the other side of the second sidewall and the third sidewall, allowing the third rail to be guided for installation and removal when it is positioned relative to the second rail or vice versa. However, the server chassis supported by industrial servo rails are becoming increasingly heavy. The aforementioned installation method requires openings in both the first and second sidewalls, causing the first rail to be pulled by the second rail, and the second rail by the third rail, leading to bending and deformation of both rails. Therefore, addressing the issue of deformation of the first and second rails under stress is a key area of ​​research and improvement for companies in this industry.

[0003] Continuing from the above, for example, patent number CN111918515B discloses a connecting piece for a middle frame. The middle frame has symmetrical grooves on its inner side, and the middle rail has an opening at the groove on its front inner side. A connecting piece is inserted into this opening and riveted to the middle rail. A guide post is mounted on the head of the connecting piece. However, the aforementioned connecting piece installation method discloses that the opening is located at the groove, i.e., the side wall of the middle frame or the patent diagram discloses that the middle frame bends and extends at the bend of the groove. When the frame is subjected to tension, the bend is prone to twisting. Furthermore, the opening of the frame reduces the moment of inertia, thus reducing the frame's torsional strength. Additionally, the connecting piece is engaged with the guide post, making it easy for the connecting piece and guide post to detach when the frame twists. Moreover, the riveting method of the connecting piece to the middle frame further reduces the production efficiency of the slide rail and increases material costs. Summary of the Invention

[0076] The structure, displacement, unfolding and folding of the first rail 1, the second rail 2 and the third rail 5 of this utility model are well known technologies and will not be described in detail here for the sake of brevity.

[0077] Please refer to Figures 1 to 3 and Figure 6. The first support member 3 has a first support body 31, which is disposed within the first mounting groove 111. The first support body 31 has two sides that bend and extend towards the first channel 10, each with a first extension portion 32.

[0078] Please refer to Figures 2 and 4 to 5. The second track 2 has a support block 23 for mounting a support fitting 4 (e.g., rivet engagement, screw locking). The support fitting 4 has a support body 41 extending vertically toward the second wall 21. Two opposite sides of the support body 41 each extend a support block 42 vertically in the same direction. Each of the two support blocks 42 has a first block portion 421 aligned with the two first support portions 33. Each of the two support blocks 42 has a second block portion 422 aligned with the two support end faces 232. Furthermore, each of the two support blocks 42 has a third support portion 43 extending horizontally along the two second sidewalls 22. The two third support portions 43 abut against... The two second sidewalls 22 are located away from the first support member 3 on the other side. The two second sidewalls 22 have a third groove 222 on their inner sides for the two third support parts 43 to abut against. The two third support parts 43 each have a bearing part 431 at their ends. The two bearing parts 431 each have a first guide feature 432 that gradually extends from the two first guide features 432. The two third support parts 43 each have a second guide feature 433 at their ends away from the two first guide features 432. The support block 23 has a support wall surface 231 that extends from the second wall 21. The end of the support wall surface 231 has a support end face 232. The ends of the two second sidewalls 22 each have the two support wall surfaces 233.

[0079] As described above, the first support member 3 is preferably made of a non-metallic material, such as plastic, and the support accessory 4 is preferably made of a non-plastic material, such as a metal material (zinc alloy). The first rail 1, the second rail 2, and the third rail 5 are made of metal, such as galvanized steel. The first support member 3 of this utility model is made of plastic and the support accessory 4 is made of zinc alloy as an example for illustration. The example is not intended to limit the patent scope of this utility model.

[0080] Please refer to Figures 7 through 11. When the first rail 1 is pulled by the second rail 2, its first support member 3 abuts against the two second sidewalls 22, the second support member 6 abuts against the two extended sidewalls 14, the two first support parts 33 abut against the first groove 121 and the two second grooves 221 respectively, and the two second support parts 63 abut against the two extended sidewalls 14 respectively. When the second rail 2 and the first rail 1 are in a retracted state, and the second rail 2 is pulled, its support accessory 4 abuts against the first support member 3. The support body 41 is attached to the support wall surface 231 of the support block 23. The support body 41 has a hollowed-out boss 411 that is attached to the support end face 232. The two first block portions 421 of the two support blocks 42 are attached to the two first support portions 33. The two second block portions 422 of the two support blocks 42 are attached to the two support walls 233 of the support block 23. The two third support portions 43 are respectively abutted against the two third sliding grooves 222 of the two second side walls 22 and the two fourth sliding grooves 521 of the two third side walls 52.

[0081] Continuing from the above, when the second rail 2 is in an unfolded state with the first rail 1, the two second support parts 63 are housed between the two extended slide grooves 141 and the two second slide grooves 221. When the second rail 2 is disassembled from the first rail 1, the two second guide parts 631 and the two first guide parts 331 are used to smoothly connect the second slide grooves 221 of the two second sidewalls 22, so that the second rail 2 can be movably disposed within the first rail 1.

[0082] Please refer to Figures 9 and 11. One end of the bead seat 24 extends gradually towards the two second sidewalls 22, with a working feature 241. Each of the two working features 241 is integrally formed into a part of the bead seat 24. When the third rail 5 is disassembled from the second rail 2 and then installed in the second channel 20, the two second guide features 433 on the support accessory 4 smoothly connect to the fourth grooves 521 of the two third sidewalls 52, allowing the third rail 5 to be movably positioned within the second rail 2. The two supporting portions 431 block the two working features 241, and the two second sidewalls 22 and the two first guide features 432 respectively cover at least one working feature 241, preventing the two third sidewalls 52 from impacting the at least one working feature 241, thus ensuring smooth connection between the fourth groove 521 and the bead seat 24.

[0083] This utility model integrates the first support member 3 and the second support member 6 into a single unit (e.g., through plastic injection molding), thereby enhancing the structural strength at the connection between the two first extensions 32 and the two first support members 33, and also enhancing the structural strength at the connection between the second extension 62 and the second support member 63. Furthermore, the first support member 3 is positioned in the first mounting groove 111, and the second support member 6 is positioned in the second mounting groove 131, using a non-locking method to simplify the product manufacturing process and improve production efficiency. Additionally, the first mounting groove 111 is located on the first wall 11, and the second... The mounting groove 131 is located on the extension wall 13. Since the first mounting groove 111 and the second mounting groove 131 do not extend to the two first side walls 12 and the two extension side walls 14, the two first side walls 12 and the two extension side walls 14 are complete structures. The two first side walls 12 and the two extension side walls 14 can have better structural strength. In this way, the cross-sectional area of ​​the two first support parts 33 and the two second support parts 63 is used to increase the overall cross-sectional area, thereby increasing the moment of inertia and achieving the effect of increasing the torsional strength of the first rail 1 to avoid deformation.

[0084] This invention uses a metal material (e.g., zinc alloy) for the support accessory 4, and the strength of the support accessory 4 is greater than that of the first rail 1, the second rail 2, the first support member 3, and the third rail 5. The support accessory 4 is installed (e.g., with rivets or screws) on the support block 23 of the second rail 2 to increase the support strength of the second wall 21, the two second side walls 22, and the two third side walls 52. This increases the cross-sectional area of ​​the support body 41, the support block 42, and the two third support parts 43, thereby increasing the cross-sectional area of ​​the two second side walls 22 and the two third side walls 52, and thus increasing the overall cross-sectional area, thereby increasing the moment of inertia and achieving the effect of increasing the torsional strength of the first rail 1 to prevent deformation.
