Description

Technical Field

[0001] This invention relates to the field of slide rail technology, and more specifically to a vertical slide rail structure. Background Technology

[0002] Data center servers are typically deployed in racks, and they are connected to the racks and pulled out via sliding rail components.

[0003] Currently, existing technologies, such as the server rack disclosed in CN108323088A and the server slide rail with cable management rack disclosed in CN116963443A, show that the standard installation position of the slide rail assembly is usually on the left and right sides of the server chassis. The chassis is fixed in the rack by the double-sided slide rails and can be pulled out for easy hardware maintenance. However, this left and right side installation method has a limited maximum load capacity, with a rated load of about 45KG or less for conventional specifications. When the total weight of the chassis exceeds its rated load threshold, it is easy to cause problems such as slide rail deformation, chassis side panel tearing, or even equipment falling and damage, posing obvious safety hazards. Therefore, the left and right side installation method is difficult to adapt to the needs of servers with higher loads (such as 50KG or more). Meanwhile, since both the left and right slide rails need to be equipped with independent limit locking structures, when the staff disassembles the entire chassis for maintenance, they need to unlock the limit locking structures of both slide rails one by one. However, the limit locking structures of the existing technology are complex, which can easily lead to cumbersome, time-consuming and labor-intensive operations. Furthermore, since both the left and right slide rails are equipped with locking structures, the overall assembly cost of a single chassis is also relatively high. Summary of the Invention

[0004] The present invention provides a vertical slide rail structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A vertical slide rail structure includes an upper slide rail body and a lower slide rail body. The upper outer rail of the upper slide rail body and the lower outer rail of the lower slide rail body are respectively mounted on the frame. The upper inner rail, which slides inside the upper outer rail, is fixedly mounted on the top of the chassis. The lower inner rail, which slides inside the lower outer rail, is fixedly mounted on the bottom of the chassis. A locking block is fixedly mounted on one end of the inner side of the lower outer rail. The surface of the locking block is provided with a protruding bracket. A locking mechanism located inside the lower inner rail is provided between the lower inner rail and the lower outer rail. The locking mechanism includes a first positioning pin and an elastic element, wherein the elastic element is a torsion spring. The first positioning pin has a first working position and a second working position. When the first positioning pin is in the first working position, during the sliding process of the lower inner rail relative to the lower outer rail, the first positioning pin abuts against the convex bracket. When the first positioning pin is in the second working position, during the sliding process of the lower inner rail relative to the lower outer rail, the lower inner rail separates from the lower outer rail.

[0006] Preferably, the locking mechanism further includes a sliding plate and a rotating plate. The mounting end of the first positioning pin is fixedly connected to the rotating plate, and the free end of the first positioning pin is used to abut against the convex bracket. One end of the elastic element is hooked onto the lower inner rail, and the other end of the elastic element is hooked onto the outside of the first positioning pin. A fourth positioning pin is fixedly installed on the surface of the lower inner rail, and the middle spring ring of the elastic element abuts against the outer peripheral surface of the fourth positioning pin. The first positioning pin is held in the first working position by the torsional force generated by the elastic element with the fourth positioning pin as the rotation center. The first positioning pin is switched to the second working position by the force transmitted by the sliding plate and the rotating plate.

[0007] Preferably, the surface of the lower inner rail is provided with an arc-shaped groove, and a second positioning pin and a third positioning pin are fixedly installed on the surface of the lower inner rail. The sliding plate is movably connected to the lower inner rail through the second positioning pin and the third positioning pin. The rotating plate is movably connected to the lower inner rail through a fourth positioning pin, and a fifth positioning pin is fixedly installed on the surface of the rotating plate. One end of the fifth positioning pin passes through the sliding plate and extends into the arc-shaped groove.

[0008] Preferably, the surface of the lower inner rail is provided with an unlocking port, and a pull button is installed at the end of the sliding plate away from the elastic element, the pull button corresponding to the unlocking port.

[0009] Preferably, the surface of the sliding plate is provided with a first stepped through hole, a second stepped through hole and an anti-pinch hole. The first stepped through hole, the second stepped through hole and the anti-pinch hole are all strip-shaped holes. The second positioning pin passes through the first stepped through hole and is connected to the lower inner rail. The third positioning pin passes through the second stepped through hole and is connected to the lower inner rail. The fifth positioning pin passes through the anti-pinch hole and extends into the arc-shaped groove.

[0010] Preferably, the sliding plate includes a wide section and a narrow section, the sliding plate is integrally formed from the wide section and the narrow section, and the pull button and the first stepped through hole are both located on the wide section, the second stepped through hole and the anti-pinch hole are both located on the narrow section, and the fourth positioning pin is located on one side of the narrow section.

[0011] Preferably, the center of the arc of the arc-shaped groove coincides with the center of the fourth positioning pin.

[0012] Preferably, the end face of the convex bracket facing the inner side of the lower outer rail is a plane, and the end face of the convex bracket facing the outer side of the lower outer rail is an inclined surface.

[0013] Preferably, one end of the inner side of the lower outer rail is provided with a bending limiting part, and the other end of the inner side of the lower outer rail is inserted with a lower guide member. The surface of the lower guide member is provided with a through mounting hole, the locking block is provided inside the mounting hole, and the surface of the lower guide member is provided with two protruding ribs. The two protruding ribs are symmetrically arranged with the mounting hole as the axis of symmetry. The bottom of the lower inner rail is provided with two arc-shaped grooves, and the lower inner rail forms a close fit with the protruding ribs through the arc-shaped grooves.

[0014] Preferably, a first guide, a ball seat, and a second guide are sequentially arranged between the lower guide and the bending limiting part. The first guide is engaged with one end of the ball seat, and the second guide is located between the ball seat and the bending limiting part. The ball seat is provided with a plurality of balls. The lower inner rail forms a close fit with the balls through an arc groove and slides on the inner side of the lower outer rail. Both sides of the ball seat are provided with limiting blocks that fit against the inner wall of the lower outer rail.

[0015] Preferably, an upper guide member is fixedly installed at one end of the upper outer rail.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: In this invention, the upper and lower sliding rails form an opposing support relationship on the upper and lower sides of the server chassis, so that the main load force of the chassis can be concentrated on the lower sliding rail at the bottom. This allows the invention to adapt to the needs of high-load servers of 50KG and above, and significantly improves the overall load-bearing capacity.

[0017] In this invention, by setting a torsion spring locking and reset structure inside the lower slide rail body, the cost and assembly complexity of the matching slide rail parts can be effectively reduced when the lower slide rail body is paired with the upper slide rail body without complex structure. This solves the problems of complex assembly, cumbersome unlocking operation and high assembly cost caused by the double-sided slide rail installation method in the prior art.

[0018] In this invention, by setting an arc-shaped groove on the lower inner rail and a raised rib on the lower guide, the lower inner rail can significantly enhance the load-bearing stability of the lower slide rail when carrying the server, relying on the mutual cooperation of the arc-shaped groove, the raised rib on the lower guide, and a number of balls on the ball seat. This ensures that the lower slide rail can be adapted to high-load usage scenarios with 50KG-70KG vertical chassis installation.

[0019] In this invention, by setting a plane and an inclined surface on the convex bracket, the assembly of the lower inner rail and the lower outer rail is simple and quick, without too many complicated steps; similarly, when the lower inner rail and the lower outer rail are separated, the unlocking movement distance is short, saving time and effort.

[0020] In this invention, the torsional force generated by the torsion spring pushes the first positioning pin, so that after the lower inner rail slides under force, the first positioning pin can abut against the convex bracket, ensuring that the chassis can be kept in a semi-pull-out state after the two abut against each other, which is conducive to manual inspection, debugging and replacement of external and local components.

[0021] In this invention, by pulling the button, the sliding plate is driven to slide, which in turn drives the rotating plate to rotate the first positioning pin, thereby ensuring that the chassis can be completely pulled out from the slide rail, so that the whole machine can be removed from the cabinet, which facilitates comprehensive maintenance, hardware replacement and circuit tidying.

[0022] In summary, this invention optimizes the overall structure and stress distribution of the slide rail, placing the upper and lower slide rails on the upper and lower sides of the chassis respectively. This ensures that the overall load is primarily borne by the lower slide rail, meeting the needs of high-load equipment. Simultaneously, the locking mechanism design allows for partial or full-range component inspection and replacement within the chassis, adapting to various maintenance scenarios. Furthermore, the design of the convex bracket, with one side being flat and the other inclined, simplifies the disassembly and assembly process of the lower slide rail, saving time and effort. Moreover, the simple locking mechanism built into the lower slide rail, combined with the streamlined upper slide rail, significantly reduces the number of parts, lowers assembly difficulty and production costs, effectively solving the problems of complex structures, cumbersome unlocking, and high operating costs associated with traditional double-sided slide rails.

[0045] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0047] like Figures 1-21 As shown, the present invention provides a vertical slide rail structure, including an upper slide rail body 1 and a lower slide rail body 2. The upper outer rail 11 of the upper slide rail body 1 and the lower outer rail 21 of the lower slide rail body 2 are respectively installed on the frame. The upper inner rail 12, which slides inside the upper outer rail 11, is fixedly installed on the top of the chassis. The lower inner rail 22, which slides inside the lower outer rail 21, is fixedly installed on the bottom of the chassis. A locking block 3 is fixedly installed on one end of the inner side of the lower outer rail 21. A protruding bracket 31 is provided on the surface of the locking block 3. A locking mechanism 4, namely a torsion spring locking and reset structure, is provided between the lower inner rail 22 and the lower outer rail 21.

[0048] By forming an opposing support relationship between the upper slide rail 1 and the lower slide rail 2 on the upper and lower sides of the server chassis 100, the main load force of the chassis can be concentrated on the lower slide rail 2 at the bottom, thereby enabling the present invention to adapt to the needs of high-load servers of 50KG and above.

[0049] Combination Figure 8 , Figure 14 , Figure 15 and Figure 16 As shown, the locking mechanism 4 includes a first positioning pin 41 and an elastic element 42. The elastic element 42 is a torsion spring. The first positioning pin 41 has a first working position and a second working position. When the first positioning pin 41 is in the first working position, during the sliding process of the lower inner rail 22 relative to the lower outer rail 21, the first positioning pin 41 abuts against the convex bracket 31. When the first positioning pin 41 is in the second working position, during the sliding process of the lower inner rail 22 relative to the lower outer rail 21, the lower inner rail 22 separates from the lower outer rail 21. That is, when the first positioning pin 41 is in the second working position, the first positioning pin 41 and the convex bracket 31 can be misaligned.

[0050] When only partial maintenance of the server chassis 100 is required, the server chassis 100 can be slightly pulled out along the slide rail. Specifically, when the first positioning pin 41 in the locking mechanism 4 is in the first working position, the operator can directly pull the server chassis 100 outward to make the first positioning pin 41 abut against the convex bracket 31. After the two abut against each other, the chassis can be kept in a semi-pull-out position, ensuring that manual inspection, debugging and replacement of external and partial components are possible.

[0051] When it is necessary to fully disassemble and perform in-depth maintenance on the internal components and back wiring of the server chassis 100, the pull button 45 can be operated to unlock the locking mechanism 4, so that the first positioning pin 41 is in the second working position, ensuring that the server chassis 100 can be completely pulled out when it is pulled out from the slide rail, so that the whole machine can be removed from the rack, making it convenient to carry out comprehensive maintenance, hardware replacement and wiring tidying.

[0052] Combination Figure 9 , Figure 15 and Figure 16 As shown, the end face of the convex bracket 31 facing the inner side of the lower outer rail 21 is a flat surface, and the end face of the convex bracket 31 facing the outer side of the lower outer rail 21 is an inclined surface. When the first positioning pin 41 is in the first working position, the first positioning pin 41 abuts against the flat surface of the convex bracket 31. The inclined surface can serve as an automatic unlocking surface when the lower inner rail 22 is inserted into the lower outer rail 21. That is, when the lower inner rail 22 drives the locking mechanism 4 to be inserted from one end of the lower outer rail 21, the first positioning pin 41 will first touch the inclined surface of the convex bracket 31. Then, as the pushing force continues to act inward, the first positioning pin 41 is forced to rotate the rotating plate 44, ensuring that the first positioning pin 41, after passing through the inclined surface and with the help of the torsion spring, can be located on one side of the flat surface of the convex bracket 31. This structural design ensures that the installation of the sliding rail 2 is simple and quick, without too many complicated steps, saving time and effort. At the same time, the design of the inclined surface on the convex bracket 31 also ensures that when the first positioning pin 41 changes its circumferential position, it can be quickly unlocked from the plane of the convex bracket 31, ensuring a short unlocking distance, thus achieving the same effect of saving time and effort.

[0053] Combination Figure 7 , Figure 8 , Figure 12 and Figure 15As shown, as a further step, the locking mechanism 4 also includes a sliding plate 43 and a rotating plate 44. The mounting end of the first positioning pin 41 is fixedly connected to the rotating plate 44, and the free end of the first positioning pin 41 is used to abut against the convex bracket 31. The surface of the lower inner rail 22 is provided with a protruding hook portion 223, and one end of the elastic member 42 is hooked on the protruding hook portion 223 of the lower inner rail 22, and the other end of the elastic member 42 is hooked on the outside of the first positioning pin 41. The surface of the lower inner rail 22 is fixedly installed with a fourth positioning pin 7, and the middle spring ring of the elastic member 42 abuts against the outer peripheral surface of the fourth positioning pin 7. The first positioning pin 41 is held in the first working position by the torsional force generated by the elastic member 42 with the fourth positioning pin 7 as the rotation center. The first positioning pin 41 is switched to the second working position by the force transmitted by the sliding plate 43 sliding and driving the rotating plate 44.

[0054] As a further reference Figures 6-8 As shown, the surface of the lower inner rail 22 is provided with an arc-shaped groove 221. The surface of the lower inner rail 22 is fixedly installed with a second positioning pin 5 and a third positioning pin 6. The sliding plate 43 is movably connected to the lower inner rail 22 through the second positioning pin 5 and the third positioning pin 6. The rotating plate 44 is movably connected to the lower inner rail 22 through a fourth positioning pin 7. The surface of the rotating plate 44 is fixedly installed with a fifth positioning pin 8. One end of the fifth positioning pin 8 passes through the sliding plate 43 and extends into the arc-shaped groove 221.

[0055] It should be noted that, as one embodiment, such as Figure 7 , Figure 8 and Figure 19 As shown, the rotating plate 44 is used in assembly, that is, the rotating plate 44 has a first pin hole, a second pin hole and a third pin hole; the first positioning pin 41 is used to be assembled in the first pin hole, the fourth positioning pin 7 is used to be assembled in the second pin hole and the fifth positioning pin 8 is used to be assembled in the third pin hole.

[0056] As another embodiment, such as Figure 20 As shown, the rotating plate 44 proposed in this solution is integrally formed. When integrally formed, the upper end face of the rotating plate 44 has a first protruding post, a second protruding post, and a circular protrusion, and the lower end face has a third protruding post. A second pin hole is formed through the surface. The first protruding post replaces the fifth positioning pin 8 and is located in the arc-shaped groove 221. The second protruding post replaces the end of the first positioning pin 41 to facilitate the hooking of the other end of the elastic element 42. The circular protrusion facilitates the abutment of the middle spring ring of the elastic element 42 to ensure stability during use. The third protruding post replaces the free end of the first positioning pin 41 and abuts against the protruding bracket 31. The second pin hole is used to assemble the fourth positioning pin 7, so that the rotating plate 44 is movably connected to the lower inner rail 22. Furthermore, when the rotating plate 44 is integrally formed, it is made of ZAMAK5 material.

[0057] Combination Figure 7 and Figure 8 As shown, specifically, the surface of the sliding plate 43 is provided with a first stepped through hole 431, a second stepped through hole 432, and an anti-pinch hole 433, all of which are strip-shaped holes; the second positioning pin 5 passes through the first stepped through hole 431 and is connected to the lower inner rail 22, wherein the free end face of the second positioning pin 5 contacts the stepped section surface of the first stepped through hole 431; the third positioning pin 6 passes through the second stepped through hole 432 and is connected to the lower inner rail 22, wherein the free end face of the third positioning pin 6 contacts the stepped section surface of the second stepped through hole 432; the fifth positioning pin 8 passes through the anti-pinch hole 433 and extends into the arc-shaped groove 221.

[0058] As a further step, the surface of the lower inner rail 22 is provided with an unlocking port 222, and a pull button 45 is installed at the end of the sliding plate 43 away from the elastic element 42, corresponding to the unlocking port 222. This structural design allows the operator to easily separate the lower inner rail 22 from the lower outer rail 21 by pulling the pull button 45 to slide the sliding plate 43. This sliding motion causes the rotating plate 44 to rotate, which in turn causes the first positioning pin 41 to rotate and misalign with the convex bracket 31, facilitating the separation of the lower inner rail 22 from the lower outer rail 21. This allows the server chassis 100 to be completely removed for comprehensive maintenance.

[0059] like Figure 7 and Figure 8 As shown, the sliding plate 43 further comprises a wide section and a narrow section, which are integrally formed. The pull button 45 and the first stepped through hole 431 are both located on the wide section, while the second stepped through hole 432 and the anti-pinch hole 433 are both located on the narrow section. The fourth positioning pin 7 is located on one side of the narrow section. This structural design ensures that after the rotating plate 44 is movably connected to the lower inner rail 22 via the fourth positioning pin 7, it does not cause structural interference between the rotating plate 44 and the sliding plate 43. The structure is simple and reasonably distributed, facilitating the process of the sliding plate 43 driving the rotating plate 44 to rotate when it slides.

[0060] Furthermore, the center of the arc of the arc-shaped slot 221 coincides with the center of the fourth positioning pin 7. Specifically, when the rotating plate 44 rotates around the fourth positioning pin 7, the fifth positioning pin 8 connected to its surface can move smoothly along the inner side of the arc-shaped slot 221, achieving precise rotation limit and guidance; and, since the anti-squeezing hole 433 is a strip hole, the fifth positioning pin 8 will not get stuck with the anti-squeezing hole 433 when it makes circular motion.

[0061] Combination Figure 9 and Figure 21As shown, as a further step, a bending limiting part 24 is provided at one end of the inner side of the lower outer rail 21, and a lower guide member 23 is inserted into the other end of the inner side of the lower outer rail 21. A mounting hole 231 is provided through the surface of the lower guide member 23, and the locking block 3 is provided inside the mounting hole 231. The surface of the lower guide member 23 is provided with two protruding ribs, which are symmetrically arranged with the mounting hole 231 as the axis of symmetry. The bottom of the lower inner rail 22 is provided with two arc-shaped grooves, and the lower inner rail 22 forms a close fit with the protruding ribs through the arc-shaped grooves.

[0062] Furthermore, a first guide 25, a ball seat 9, and a second guide 26 are sequentially arranged between the lower guide 23 and the bending limiting part 24. The first guide 25 is engaged with one end of the ball seat 9, and the second guide 26 is located between the ball seat 9 and the bending limiting part 24. The ball seat 9 is provided with a number of balls, and the lower inner rail 22 forms a close fit with the balls through an arc groove. Both sides of the ball seat 9 are provided with limiting blocks 27 that fit against the inner wall of the lower outer rail 21.

[0063] The first guide 25, the second guide 26 and the limiting block 27 can effectively limit and fix the ball seat 9, ensure the stable operation of the ball seat 9 and prevent the balls from slipping and falling off.

[0064] As a further step, the surfaces of the lower guide member 23, the first guide member 25 and the second guide member 26 are all provided with guide tilting openings, which facilitate the easy assembly of the lower inner rail 22 onto the inner side of the lower outer rail 21.

[0065] This solution uses a lower outer rail 21, a lower inner rail 22, a lower guide 23, a first guide 25, a second guide 26, a limiting block 27, a locking block 3, and a locking mechanism 4 to form the lower slide rail body 2, enabling the lower slide rail body 2 structure to effectively support high-load servers. Specifically, this solution relies on molding the lower inner rail 22 into a single piece of sheet metal with two arc-shaped grooves, which effectively improves its overall structural strength. Thus, when the lower inner rail 22 supports the server, the arc-shaped grooves, in conjunction with the ribs on the lower guide 23 and several balls on the ball seat 9, ensure that the lower slide rail body 2 has strong load-bearing stability, making it suitable for high-load usage scenarios with 50KG-70KG vertical chassis installation.

[0066] Furthermore, the material of the sliding track 2 can be made of HC420LA to ensure that the sliding track 2 can adapt to the high load requirements of servers with a load of 50KG and above, greatly improving the overall load-bearing capacity.

[0067] As a further step, one end of the lower outer rail 21 is connected to a lower guide member 23, and a mounting hole 231 is formed through the surface of the lower guide member 23. The locking block 3 is located inside the mounting hole 231. The lower guide member 23 is inserted into one end of the lower outer rail 21. When the locking block 3 is fixedly connected to the lower outer rail 21 by the positioning member, the lower guide member 23 can achieve the anti-loosening effect. Furthermore, after the lower guide member 23 is stabilized, it can also limit the limiting block on one side of the ball seat 9, ensuring the stability of the ball seat 9.

[0068] Combination Figures 2-4 As shown, as a further step, an upper guide member 13 is fixedly installed at one end of the upper outer rail 11. In this invention, the upper slide rail body 1 is installed on the top of the server chassis 100, and it is composed of an upper outer rail 11, an upper inner rail 12 and an upper guide member 13. It eliminates the need for complex structures such as locking blocks 3, locking mechanisms 4 and ball seats 9, which can effectively reduce the cost of parts and the complexity of assembly.

[0069] Specifically, the present invention adopts a vertical upper and lower sliding rail design with server chassis 100, so that the main load of server chassis 100 is concentrated on the lower sliding rail 2 at the bottom, while the upper sliding rail 1 at the top only needs to perform the guiding function, without the need for additional load-bearing structure and double-sided locking mechanism 4. This ensures that the present invention not only improves the overall load-bearing capacity, but also avoids the problems of cumbersome unlocking operation and high assembly cost caused by the double-sided sliding rail installation method in the prior art.

[0070] This invention employs an upper and lower sliding rail support structure, concentrating the load primarily on the lower sliding rail body 2, significantly enhancing its load-bearing capacity and adapting to the needs of high-load servers. Furthermore, the design of the torsion spring locking structure and the irregularly shaped convex bracket 31 simplifies the disassembly and unlocking steps of the sliding rail, reducing operational difficulty and minimizing the number of parts used, thus lowering production costs. Simultaneously, the vertical sliding rail structure proposed in this invention supports both partial pull-out maintenance and full pull-out maintenance of the server equipment, offering flexibility and convenience, effectively overcoming the problems of weak load-bearing capacity, complex structure, and cumbersome operation of existing sliding rails.

[0071] Working principle and usage of this invention: The upper inner rail 12 and the lower inner rail 22 are respectively installed on the upper and lower surfaces of the server chassis 100 using matching screws; Install the upper outer rail 11 and the lower outer rail 21 onto the inner top wall and inner bottom wall of the cabinet respectively using matching screws to ensure that the upper outer rail 11 and the lower outer rail 21 are vertically aligned. The server chassis 100 and inner rail are installed onto the outer rail located on the rack, and the chassis is pushed into place to complete the installation of the server chassis 100. Among them, the upper inner rail 12 can be directly installed into the upper outer rail 11, and when the lower inner rail 22 is installed into the lower outer rail 21, the first positioning pin 41 will first touch the inclined surface of the convex bracket 31. As the force is continuously applied, the first positioning pin 41 can drive the rotating plate 44 to rotate after being stressed. This ensures that the first positioning pin 41 can be located on one side of the plane of the convex bracket 31 after passing through the inclined surface and with the help of the torsion spring, so as to complete the assembly of the inner rail and the outer rail. When only partial maintenance of the server chassis 100 is required, the staff can directly pull the server chassis 100 outward. At this time, the first positioning pin 41 is held in the first working position by the force of the torsion spring. When the inner rail 22 slides under force, the first positioning pin 41 can abut against the convex bracket 31. After the two abut against each other, the chassis can be held in a half-pull-out position, ensuring that the staff can perform manual maintenance, debugging and replacement of external and local components.

[0072] When a comprehensive disassembly and in-depth maintenance of the internal components and back wiring of the server chassis 100 is required, the operator can slide out one end of the lower inner rail 22 and manually pull the pull button 45 from the bottom of the lower inner rail 22. After the pull button 45 is pulled, the sliding plate 43 can slide. When the sliding plate 43 slides, it can drive the fifth positioning pin 8 to move along the inside of the arc-shaped groove 221 with the help of the anti-pinch hole 433. This allows the rotating plate 44 to rotate around the fourth positioning pin 7 as the center, ensuring that the first positioning pin 41 can be in the second working position after the rotating plate 44 rotates. Thus, when the first positioning pin 41 and the convex bracket 31 are misaligned and their directions of movement do not collide, the server chassis 100 can be completely pulled out from the slide rail, allowing the entire machine to be removed from the rack, which facilitates comprehensive maintenance, hardware replacement and wiring repair. When the pulling force of the pull button 45 is manually released, the elastic element 42 (torsion spring) can rotate around the fourth positioning pin 7 to generate a torsional force, thereby enabling the first positioning pin 41 to be reset from the second working position to the first working position.

[0073] In summary, the present invention has the following advantages over the prior art: I. The present invention forms an opposing support relationship between the upper slide rail 1 and the lower slide rail 2 on the upper and lower sides of the server chassis 100, so that the main load force of the chassis can be concentrated on the lower slide rail 2 at the bottom. This allows the present invention to adapt to the needs of high load servers of 50KG and above, and greatly improve the overall load-bearing capacity.

[0074] Second, in this invention, by setting a torsion spring locking and reset structure on the inner side of the lower slide rail 2, the lower slide rail 2 can effectively reduce the cost and assembly complexity of the matching slide rail parts when paired with the upper slide rail 1 which has no complex structure, thus solving the problems of complex assembly, cumbersome unlocking operation and high assembly cost caused by the double-sided slide rail installation method in the prior art.

[0075] Third, in this invention, by setting a plane and an inclined surface on the convex bracket 31, the assembly of the lower inner rail 22 and the lower outer rail 21 is simple and quick, without too many complicated steps; similarly, when the lower inner rail 22 and the lower outer rail 21 are separated, the unlocking movement distance can be ensured to be short, saving time and effort.

[0076] Fourth, in this invention, the torsional force generated by the torsion spring pushes the first positioning pin 41, so that after the lower inner rail 22 is slid under force, the first positioning pin 41 can abut against the convex bracket 31, ensuring that the chassis can be kept in a semi-pull-out state after the two abut against each other, which is conducive to manual inspection, debugging and replacement of external and local components.

[0077] V. In this invention, by pulling the button 45, the sliding plate 43 is driven to slide, so that when the sliding plate 43 slides, it can drive the rotating plate 44 to rotate the first positioning pin 41, thereby ensuring that the chassis can be completely pulled out from the slide rail, realizing the removal of the whole machine from the cabinet, which facilitates comprehensive maintenance, hardware replacement and circuit tidying.

[0078] It is worth noting that the present invention Figures 1 to 16 This mainly showcases the specific structure of the slide rail body and the locking mechanism 4; when applied to Figure 17 Under the operating conditions shown, each component can be adapted to be lengthened according to actual needs, while the overall structure and working principle remain unchanged.
