Description

Technical Field

[0001] This utility model relates to the field of slide rail installation technology, and in particular to a tool-free mounting bracket for server slide rails and a slide rail assembly. Background Technology

[0002] In today's era of rapid information technology development, servers, as the core equipment of data centers, play a crucial role in the efficient operation of these centers through efficient installation and maintenance. However, traditional server rail installation methods mostly rely on bolt fixing. This method is not only inefficient, requiring professionals to spend a lot of time tightening each bolt individually, but also significantly increases operational complexity and makes maintenance extremely inconvenient when servers need to be frequently installed and disassembled. Furthermore, bolts may loosen over long-term use, affecting the stability of the server rails and posing potential risks to the normal operation of the server.

[0003] To address these pain points, tool-free server rail brackets have gradually emerged in the market. Through innovative locking mechanisms, they allow for quick installation and disassembly without tools, significantly improving installation efficiency. However, existing tool-free mounting brackets still have several limitations in practical applications. Firstly, some brackets have complex structural designs, increasing manufacturing costs and reducing product reliability and stability. Secondly, some brackets lack intuitive operation methods, potentially causing user difficulties and impacting the user experience. Furthermore, existing brackets have limited adaptability to different server column structures and diverse installation environments, failing to meet the growing demand for personalized installations.

[0004] Against this backdrop, prior art document (CN106535552B) discloses a tool-free mounting bracket for the rear of a server rack slide rail. This bracket uses hooks to fix the rear bracket to the server column. While this improves installation efficiency to some extent, the design still has significant drawbacks. Specifically, the rear bracket in this prior art document requires a clear distinction between left and right; the left rear bracket can only be installed on the left server column, and the right rear bracket can only be installed on the right server column. This design not only increases the difficulty of identification during installation but also increases the complexity of operation, making it easy for installers to become confused in actual operation, thereby reducing installation efficiency and increasing the probability of errors. Utility Model Content

[0005] The purpose of this utility model is to provide a tool-free mounting bracket and rail assembly for server slide rails. The symmetrical structural design allows the rear bracket to be used on both left and right server columns without the need for left-right distinction, simplifying the installation process and improving the convenience and versatility of installation.

[0006] In a first aspect, this utility model provides a tool-free mounting bracket for server slide rails, comprising:

[0007] The rear support includes an integrally formed bottom wall and a side wall. The side wall is located at the end of the bottom wall that is fixed to the server column. The bottom wall is provided with a rotating bracket, and the side wall is provided with mounting holes that pass through opposite ends.

[0008] An elastic locking assembly includes a locking member and a torsion spring. The locking member is rotatably mounted on the rotating bracket. The torsion spring provides a reset torque to the locking member. One end of the locking member passes through the mounting hole, and the end of the locking member passing through the mounting hole has a hook portion facing or away from the bottom wall. The hook portion can rotate around the rotating bracket to move away from or towards the bottom wall, so that the hook portion can pass through the fixing hole of the server column and allow the torsion spring to accumulate elastic force. The torsion spring can also release the elastic force, so that the hook portion rotates around the rotating bracket to its reset position and fixes the locking member in the fixing hole of the server column.

[0009] This utility model provides a tool-free mounting bracket for server slide rails. By rotating the bracket around a hook portion to face or move away from the bottom wall, the hook portion can be inserted into a mounting hole on the server column. When the hook portion enters the mounting hole, a torsion spring releases its elastic force, driving the hook portion to reset and lock onto the server column, thus fixing the locking element in the mounting hole. This enables quick installation and disassembly without tools, significantly reducing installation and maintenance time. Furthermore, by positioning the hook portion on the side of the locking element facing or away from the bottom wall, the overall structure is symmetrical, accommodating server columns in both left and right orientations. This eliminates the need to distinguish between left and right brackets for installation, simplifying the installation process and improving ease of installation and versatility.

[0010] Furthermore, the rotating bracket extends to provide a blocking portion, the locking member extends to provide a limiting portion, and the torsion spring includes a torsion spring body, a blocking rod, and a limiting rod. The blocking rod and the limiting rod are respectively located on opposite sides of the torsion spring body. The blocking rod abuts against the blocking portion, and the limiting rod abuts against the limiting portion.

[0011] Using the above technical solution, the two ends of the torsion spring abut against the rotating bracket and the locking component, respectively. When the locking component rotates, the torsion spring, supported by the blocking rod and the limiting rod on the blocking and limiting parts, can effectively accumulate and release elastic force. This design ensures that the hook part can accurately and stably lock onto the server column or release from the server column during locking and unlocking.

[0012] Furthermore, the locking component includes a first locking part, a second locking part, a connecting plate, and a rotating shaft. The first locking part and the second locking part are located on opposite sides of the connecting plate. The rotating shaft passes through the first locking part, the rotating bracket, and the second locking part in sequence. The first locking part is provided with a first hook part, and the second locking part is provided with a second hook part.

[0013] The above technical solution includes a first hook portion on the first locking part and a second hook portion on the second locking part. This double-hook design provides a dual locking mechanism, significantly improving the locking reliability between the locking component and the server column. Even if one hook portion fails, the other hook portion remains locked, ensuring stable installation of the server slide rail. Furthermore, the first and second locking parts are located on opposite sides of the connecting plate, forming a symmetrical structure. This symmetrical design not only enhances structural stability but also allows the locking component to better adapt to forces in different directions, further improving locking reliability.

[0014] Furthermore, the rotating bracket extends to provide a blocking portion, the first locking portion extends to provide a first limiting portion, the second locking portion extends to provide a second limiting portion, and the torsion spring includes a first torsion spring body, a second torsion spring body, a first limiting rod, a second limiting rod, and a blocking rod. The first torsion spring body and the second torsion spring body are respectively disposed at opposite ends of the blocking rod, and the first limiting rod and the second limiting rod are respectively disposed at the ends of the first torsion spring body and the second torsion spring body away from the blocking rod. The blocking rod abuts against the blocking portion, and the first limiting rod and the second limiting rod abut against the first limiting portion and the second limiting portion, respectively.

[0015] By employing the above technical solution, a first torsion spring body and a second torsion spring body are respectively configured to cooperate with the first locking part and the second locking part, providing dual elastic force support. This double torsion spring design not only enhances the locking force of the locking component but also improves its stability and reliability during long-term use. The interaction between the blocking rod and the blocking part, as well as the interaction between the first and second limiting rods and their corresponding limiting parts, ensures that the locking component can accurately reach the locking or unlocking position during rotation, reducing the risk of locking failure due to structural loosening or jamming.

[0016] Furthermore, the connecting plate is provided with a wrench at one end through the mounting hole, the wrench being used to drive the first locking part and the second locking part to rotate around the rotating axis away from the bottom wall.

[0017] With the above technical solution, the wrench is located at one end of the connecting plate through the mounting hole, providing the operator with an intuitive and easy-to-operate handle. Using the wrench, the operator can easily drive the first and second locking parts to rotate around the rotating shaft, thus unlocking the hook part without the need for additional tools, significantly improving the convenience and efficiency of operation.

[0018] Furthermore, the wrench portion extends away from the hook portion.

[0019] By adopting the above technical solution, the wrench extends away from the hook portion, so that the wrench will not interfere with the hook portion or other components during operation, reducing the operational difficulties caused by mutual interference between components and further improving the smoothness of operation.

[0020] Furthermore, the extension length of the hook portion toward the bottom wall is set to decrease from near the torsion spring to far away from the torsion spring.

[0021] Using the above technical solution, the extension length of the hook portion decreases progressively from near torsion spring to far away from it. This design provides automatic guidance as the hook portion approaches the mounting hole of the server column. As the hook portion penetrates deeper into the mounting hole, it rotates relative to the bottom wall of the rotating bracket. When the hook portion completely passes through the mounting hole, the torsion spring releases its elastic force, locking the hook portion firmly onto the column surface. This design reduces installation difficulties caused by inaccurate alignment, improving installation convenience and efficiency.

[0022] Furthermore, it also includes a positioning stud and a fixing nut. The positioning stud has a threaded section, and the side wall also has a positioning hole. The threaded section can pass through the positioning hole. The fixing nut is threadedly connected to the threaded section. The end of the positioning stud away from the threaded section can be inserted into the fixing hole of the server column for positioning.

[0023] The above technical solution provides additional fixing points for the positioning studs and fixing nuts, ensuring that the rear bracket can be accurately positioned on the server column. The threaded section on the positioning stud connects with the threaded section of the fixing nut, allowing the rear bracket to be more stably fixed to the server column during installation, reducing the risk of slide rail loosening or displacement due to insecure installation.

[0024] Furthermore, there are two positioning studs and two fixing nuts, and two positioning holes are provided on opposite sides of the mounting hole.

[0025] By employing the above technical solution and incorporating two positioning studs and two fixing nuts, more fixing points are provided, significantly enhancing the connection strength between the rear bracket and the server column. This dual-fixation design ensures that the rear bracket is more stably secured to the server column during installation, reducing the risk of slide rail loosening or displacement due to insecure installation.

[0026] Secondly, the present invention provides a slide rail assembly comprising:

[0027] Tool-free mounting brackets for any of the above server rails;

[0028] The server column is provided with multiple fixing holes, which are spaced apart along the height direction of the server column. The hook part can pass through one of the fixing holes and allow the torsion spring to accumulate elastic force. The torsion spring can release the elastic force after the hook part has completely passed through the fixing hole, so that the hook part is fixed in the fixing hole.

[0029] The telescopic frame is located at the end of the bottom wall away from the side wall.

[0030] As can be seen from the above, the tool-free mounting bracket for server slide rails provided by this utility model allows the hook portion to rotate around the bracket to face or move away from the bottom wall, enabling it to be inserted into the fixing hole on the server column. When the hook portion enters the fixing hole of the server column, the torsion spring releases its elastic force to drive the hook portion to reset and lock the server column, thereby fixing the locking component in the fixing hole of the server column, achieving quick installation and disassembly without the need for tools, significantly reducing installation and maintenance time. Furthermore, by placing the hook portion on the side of the locking component facing or away from the bottom wall, the overall structure is symmetrical, thus adapting to server columns in both left and right orientations, eliminating the need to distinguish between left and right brackets for installation, simplifying the installation process, and contributing to improved installation convenience and versatility.

Detailed Implementation

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] This utility model discloses a tool-free mounting bracket for server slide rails, primarily used in server slide rail installation. The tool-free mounting bracket employs a symmetrical structural design, allowing the rear bracket to be used on both left and right server columns without requiring differentiation between left and right sides. This simplifies the installation process and improves ease of installation and versatility.

[0041] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 In one embodiment, the tool-free mounting bracket for the server slide rail includes a rear bracket 100 and an elastic locking assembly 200. The rear bracket 100 includes an integrally formed bottom wall 110 and a side wall 120. The side wall 120 is located at the end of the bottom wall 110 that is fixed to the server column 500. A rotating bracket 130 is provided on the bottom wall 110, and mounting holes 121 extending through opposite ends are provided on the side wall 121. The elastic locking assembly 200 includes a locking member 210 and a torsion spring 220. The locking member 210 is rotatably mounted on the rotating bracket 130, and the torsion spring 220 provides a reset torque to the locking member 210. One end of the locking member 210 passes through the mounting hole 121. The locking member 210 has a hook portion 211 at one end passing through the mounting hole 121, facing or away from the bottom wall 110. The hook portion 211 can rotate around the rotating bracket 130 to move away from or towards the bottom wall 110, so that the hook portion 211 can pass through the fixing hole 510 of the server column 500 and allow the torsion spring 220 to accumulate elastic force. The torsion spring 220 can also release the elastic force, so that the hook portion 211 rotates around the rotating bracket 130 to return to its original position and fixes the locking member 210 in the fixing hole 510 of the server column 500.

[0042] It is worth noting that when the locking member 210 has a hook portion 211 at one end passing through the mounting hole 121 and facing the bottom wall 110 (as shown in the attached diagram) Figure 3 As shown), the hook portion 211 can rotate around the rotating bracket 130 to move away from the bottom wall 110, so that the hook portion 211 can pass through the fixing hole 510 of the server column 500 and allow the torsion spring 220 to accumulate elastic force; conversely, when the locking member 210 has a hook portion 211 facing away from the bottom wall 110 at one end passing through the mounting hole 121 (not shown), the hook portion 211 can rotate around the rotating bracket 130 to move towards the bottom wall 110, so that the hook portion 211 can pass through the fixing hole 510 of the server column 500 and allow the torsion spring 220 to accumulate elastic force.

[0043] As can be seen from the above, the tool-free mounting bracket for server slide rails provided by this utility model allows the hook portion 211 to rotate around the rotating bracket 130 to move towards or away from the bottom wall 110, enabling the hook portion 211 to be inserted into the fixing hole 510 on the server column 500. When the hook portion 211 enters the fixing hole 510 of the server column 500, the torsion spring 220 releases its elastic force to drive the hook portion 211 to reset and lock the server column 500, thereby fixing the locking member 210 in the fixing hole 510 of the server column 500, achieving quick installation and disassembly without the need for tools, significantly reducing installation and maintenance time. In addition, by setting the hook portion 211 on the side of the locking member 210 facing or away from the bottom wall 110, the whole structure forms a symmetrical structure, thus adapting to server columns 500 in both left and right positions, eliminating the need to distinguish between left and right brackets for installation, simplifying the installation process, and helping to improve the convenience and versatility of installation.

[0044] Reference Appendix Figure 2 Appendix Figure 4 In one embodiment, the rotating bracket 130 extends to provide a blocking part 131, the locking member 210 extends to provide a limiting part 212, and the torsion spring 220 includes a torsion spring body 221, a blocking rod 222 and a limiting rod 223. The blocking rod 222 and the limiting rod 223 are respectively provided on opposite sides of the torsion spring body 221. The blocking rod 222 abuts against the blocking part 131, and the limiting rod 223 abuts against the limiting part 212.

[0045] Using the above technical solution, the two ends of the torsion spring 220 abut against the rotating bracket 130 and the locking member 210, respectively. When the locking member 210 rotates, the torsion spring 220, supported by the blocking rod 222 and the limiting rod 223 on the blocking part 131 and the limiting part 212, can effectively accumulate and release elastic force. This design ensures that the hook part 211 can accurately and stably lock onto the server column 500 or release from the server column 500 during locking and unlocking.

[0046] Reference Appendix Figure 4 In one embodiment, the locking member 210 includes a first locking part 213, a second locking part 214, a connecting plate 215, and a rotating shaft 216. The first locking part 213 and the second locking part 214 are located on opposite sides of the connecting plate 215. The rotating shaft 216 passes through the first locking part 213, the rotating bracket 130, and the second locking part 214 in sequence. The first locking part 213 is provided with a first hook part 2131, and the second locking part 214 is provided with a second hook part (not shown in the figure).

[0047] Using the above technical solution, the first locking part 213 is provided with a first hook part 2131, and the second locking part 214 is provided with a second hook part. This double hook design provides a dual locking mechanism, significantly improving the locking reliability between the locking member 210 and the server column 500. Even if one hook part fails, the other hook part can still remain locked, ensuring the stable installation of the server slide rail. In addition, the first locking part 213 and the second locking part 214 are located on opposite sides of the connecting plate 215, forming a symmetrical structure. This symmetrical design not only enhances the stability of the structure but also allows the locking member 210 to better adapt to forces in different directions, further improving the locking reliability.

[0048] In one embodiment, the rotating bracket 130 extends to provide a blocking portion 131, the first locking portion 213 extends to provide a first limiting portion 2132, the second locking portion 214 extends to provide a second limiting portion 2141, and the torsion spring 220 includes a first torsion spring body 224, a second torsion spring body 225, a first limiting rod 226, a second limiting rod 227, and a blocking rod 222. The first torsion spring body 224 and the second torsion spring body 225 are respectively located at opposite ends of the blocking rod 222, and the first limiting rod 226 and the second limiting rod 227 are respectively located at the ends of the first torsion spring body 224 and the second torsion spring body 225 away from the blocking rod 222. The blocking rod 222 abuts against the blocking portion 131, and the first limiting rod 226 and the second limiting rod 227 abut against the first limiting portion 2132 and the second limiting portion 2141, respectively.

[0049] By adopting the above technical solution, a first torsion spring body 224 and a second torsion spring body 225 are provided, which cooperate with the first locking part 213 and the second locking part 214 respectively, providing dual elastic force support. This double torsion spring design not only enhances the locking force of the locking member 210, but also improves the stability and reliability of the locking member 210 during long-term use. The interaction between the blocking rod 222 and the blocking part 131, as well as the interaction between the first limiting rod 226 and the second limiting rod 227 and their respective limiting parts, ensure that the locking member 210 can accurately reach the locking or unlocking position during rotation, reducing the risk of locking failure due to structural loosening or jamming.

[0050] In one embodiment, the connecting plate 215 is provided with a wrench part 230 at one end through the mounting hole 121. The wrench part 230 is used to drive the first locking part 213 and the second locking part 214 to rotate around the rotating shaft 216 away from the bottom wall 110.

[0051] With the above technical solution, the wrench part 230 is located at one end of the connecting plate 215 through the mounting hole 121, providing the operator with an intuitive and easy-to-operate handle. Through the wrench part 230, the operator can easily drive the first locking part 213 and the second locking part 214 to rotate around the rotating shaft 216, thereby unlocking the hook part 211 without the need for additional tools, significantly improving the convenience and efficiency of operation.

[0052] In one embodiment, the wrench portion 230 extends away from the hook portion 211.

[0053] By adopting the above technical solution, the wrench part 230 extends away from the hook part 211, so that the wrench part 230 will not interfere with the hook part 211 or other components during operation, reducing the operational difficulties caused by mutual interference between components and further improving the smoothness of operation.

[0054] In one embodiment, the extension length of the hook portion 211 toward the bottom wall 110 decreases from near the torsion spring 220 to far away from the torsion spring 220.

[0055] Using the above technical solution, the extension length of the hook portion 211 decreases gradually from near torsion spring 220 to far away from torsion spring 220. This design provides automatic guidance when the hook portion 211 is about to enter the mounting hole 510 of the server column 500. As the hook portion 211 continues to penetrate deeper into the mounting hole 510 of the server column 500, it rotates relative to the bottom wall 110 around the rotating bracket 130. When the hook portion 211 has completely passed through the mounting hole 510 of the server column 500, the torsion spring 220 releases its elastic force, causing the hook portion 211 to lock onto the column surface of the server column 500. This design reduces installation difficulties caused by inaccurate alignment and improves the convenience and efficiency of installation.

[0056] In one embodiment, it also includes a positioning stud 300 and a fixing nut 400. The positioning stud 300 is provided with a threaded section 310 and a positioning hole 122 is provided on the side wall 120. The threaded section 310 can pass through the positioning hole 122. The fixing nut 400 is threadedly connected to the threaded section 310. The end of the positioning stud 300 away from the threaded section 310 can be inserted into the fixing hole 510 of the server column 500 for positioning.

[0057] By adopting the above technical solution, the design of the positioning stud 300 and the fixing nut 400 provides additional fixing points, ensuring that the rear bracket 100 can be accurately positioned on the server column 500. The threaded section 310 on the positioning stud 300 is threadedly connected to the fixing nut 400, which allows the rear bracket 100 to be more stably fixed on the server column 500 during installation, reducing the risk of the slide rail loosening or shifting due to insecure installation.

[0058] In one embodiment, there are two positioning studs 300 and two fixing nuts 400, and two positioning holes 122 are provided on opposite sides of the mounting hole 121.

[0059] By adopting the above technical solution, and by setting two positioning studs 300 and two fixing nuts 400, more fixing points are provided, significantly enhancing the connection strength between the rear bracket 100 and the server column 500. This dual fixing design ensures that the rear bracket 100 can be more stably fixed to the server column 500 during installation, reducing the risk of slide rail loosening or displacement due to insecure installation.

[0062] The server column 500 is provided with multiple fixing holes 510. The multiple fixing holes 510 are spaced apart along the height direction of the server column 500. The hook part 211 can pass through one of the fixing holes 510 and allow the torsion spring 220 to accumulate elastic force. The torsion spring 220 can release the elastic force after the hook part 211 has completely passed through the fixing hole 510, so that the hook part 211 is fixed in the fixing hole 510.
