Description

Technical Field

[0001] This application relates to the field of GPU server technology, specifically to a quick assembly / disassembly fixture for GPU servers and a GPU server. Background Technology

[0002] In recent years, with the rapid development of fields such as artificial intelligence, high-performance computing, and graphics rendering, the performance and integration density of graphics processing units (GPUs), as core computing units, have continued to improve, and the power consumption of GPU servers has also been increasing. To address the problem of rapid temperature rise caused by the high power consumption of GPU servers, the cooling solution used in GPU servers has shifted from air cooling to liquid cooling. To better adapt to liquid cooling structures, most GPU server manufacturers currently use a blind-plug connection scheme when installing GPUs. This involves connecting the GPU to key components of the liquid cooling system (such as liquid cooling manifolds, cold plates, and liquid cooling headers) via blind-plug quick-connect connectors, and then securing the GPU to the GPU server chassis with screws.

[0003] However, the limited space within a GPU server chassis, coupled with the side-by-side arrangement of multiple graphics processors, makes disassembly and assembly difficult due to the limited operating space in all directions. Furthermore, the use of quick-connect fittings requires sustained pressure on the graphics processor during screw tightening to overcome the spring-loaded force of the fittings and maintain its stability relative to the chassis, further complicating the disassembly and assembly process. Summary of the Invention

[0004] This application aims to address one of the technical problems in related technologies to a certain extent. To this end, this application provides a quick assembly / disassembly fixture for GPU servers and a GPU server itself.

[0005] To achieve the above objectives, this application adopts the following technical solution: a quick-release fixture for GPU servers, used to disassemble and install a graphics processor relative to the chassis in a GPU server. The quick-release fixture includes a mounting bracket and a docking bracket. The mounting bracket includes a first frame and a first snap-fit ​​structure disposed on the first frame. The docking bracket includes a second frame and a second snap-fit ​​structure disposed on the second frame. The first frame is provided with a first mounting part and a second mounting part for detachable connection with the graphics processor and the chassis, respectively. The first frame is configured to be positioned to the chassis via the first snap-fit ​​structure. The second frame includes a base plate, a gripping part disposed on the base plate, and a locking part disposed on the base plate. The second frame is configured to be positioned to the graphics processor and the mounting bracket by cooperating with the second snap-fit ​​structure and the locking part. The gripping part is higher than the graphics processor and the mounting bracket when the second frame is positioned to the graphics processor and the mounting bracket.

[0006] The application of this application has the following beneficial effects: By setting a mounting bracket and a second mounting part on the first frame, the graphics processor can be installed into the chassis via the mounting bracket. Simultaneously, by setting a first snap-fit ​​structure, the graphics processor and mounting bracket can be pre-positioned into the chassis during the installation process, eliminating the need for continuous pressing of the graphics processor by the operator, thus facilitating installation with both hands. Furthermore, by setting a docking bracket, the second snap-fit ​​structure and engaging part in the docking bracket can be used to pre-position the docking bracket on the graphics processor and mounting bracket. Then, the gripping part on the docking bracket can be used to move the graphics processor and mounting bracket for disassembly and assembly operations. Since the gripping part is higher than the graphics processor and mounting bracket, it does not occupy space in the front-back, left-right, and right directions of the graphics processor during disassembly and assembly operations, reducing the difficulty for the operator in grasping, placing, and pressing the graphics processor, and improving the convenience of disassembly and assembly operations.

[0007] Optionally, the first snap-fit ​​structure includes a first slider slidably disposed on the first frame and a first elastic member disposed between the first slider and the first frame. The first slider is formed with a slot for adapting to a snap-fit ​​block disposed on the chassis. The first elastic member applies pressure to the first slider such that the slot tends to move away from the docking bracket.

[0008] Optionally, the first slider is provided with an upper plate, a lower plate, and a connecting plate disposed between the upper plate and the lower plate. The upper plate and the lower plate are spaced apart and form the bayonet between them. The lower plate is provided with a guide slope for cooperating with the card block of the chassis.

[0009] Optionally, the mounting bracket further includes:

[0010] A connecting block, which is fixedly installed on the first frame and is provided with a sliding groove;

[0011] A limiting cover plate, which is fixedly installed on the connecting block, covers the top of the sliding groove and has a sliding hole corresponding to the sliding groove; and,

[0013] The first slider is slidably disposed in the slide groove, the first elastic element is disposed between the first slider and the inner wall of the slide groove, the lower clamping plate extends out of the slide groove, the connecting plate extends out of the slide groove through the sliding hole, and the upper clamping plate passes through the through hole.

[0014] Optionally, the end of the limiting cover away from the limiting baffle is formed with a limiting portion that extends out of the edge of the connecting block, and the limiting portion is used to cooperate with the engaging portion.

[0015] Optionally, both the first mounting part and the second mounting part are connecting holes for screws to pass through, and the opening direction of the first mounting part is the front-to-back direction, while the opening direction of the second mounting part is the up-and-down direction.

[0016] Optionally, the second snap-fit ​​structure includes a second slider slidably disposed on the substrate and a second elastic member disposed between the second slider and the substrate. The second slider is formed with a snap-fit ​​portion adapted to a slot structure in a graphics processor. The second elastic member applies pressure to the second slider such that the snap-fit ​​portion tends to move away from the mounting bracket.

[0017] Optionally, the mounting bracket further includes a limiting structure mounted on the substrate. The second slider is provided with an elongated hole. The limiting structure includes a limiting cover plate located on the other side of the second slider relative to the substrate and a limiting block passing through the elongated hole. The limiting structure is detachably connected to the substrate through the limiting block, and the dimension of the limiting block along the length direction of the elongated hole is smaller than that of the elongated hole.

[0018] Optionally, the second frame also includes a left side plate and a right side plate. The left side plate, the right side plate, and the gripping part are all integrally formed with the base plate. The gripping part is located above the base plate. The left side plate and the right side plate are arranged at intervals with the second buckle structure along the front-back direction and are located on the left and right sides of the base plate, respectively. The locking part is formed at the end of the left side plate and the right side plate away from the second buckle structure.

[0019] Furthermore, this application also provides a GPU server, including a chassis and multiple graphics processors. The chassis has an opening and a mounting plate. The graphics processors are mounted to the mounting plate through the opening. The GPU server also includes a quick-release fixture as described in any of the above technical solutions. The mounting bracket is detachably connected to the graphics processors via a first mounting part, and the mounting bracket is detachably connected to the mounting plate via a second mounting part. A locking block is provided on the upper surface of the mounting plate, and the mounting bracket is also positioned by engaging with the locking block via a first snap-fit ​​structure. The beneficial effects of the GPU server provided in this application are similar to those of the aforementioned quick-release fixture, and will not be repeated here.

[0020] Optionally, the upper surface of the mounting plate is further provided with a slot extending downward from the upper surface. The first frame includes a first vertical plate, a second vertical plate, a first horizontal plate disposed on the first vertical plate, and a second horizontal plate disposed on the second vertical plate. The first vertical plate and the second vertical plate are perpendicular to each other. The first buckle structure is disposed on the first horizontal plate, the first mounting part is disposed on the first vertical plate, and the second mounting part is disposed on the second horizontal plate. The second vertical plate is inserted into the slot when the first buckle structure engages with the buckle block.

Detailed Implementation

[0036] The embodiments of this application 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 are intended to explain this application and should not be construed as limiting it.

[0037] The terms "an embodiment," "example," or "example" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this application. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0038] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] As a first aspect of this application, this embodiment provides a quick-release fixture for a GPU server, which is used to install and remove a graphics processor 3 relative to a chassis 4 within the GPU server. Figures 1 to 9 As shown, the quick assembly / disassembly fixture includes an installation bracket 1 and a docking bracket 2. The installation bracket 1 includes a first frame 10 and a first snap-fit ​​structure 11 disposed on the first frame 10. The docking bracket 2 includes a second frame 20 and a second snap-fit ​​structure 21 disposed on the second frame 20.

[0041] The first frame 10 is provided with a first mounting part 1000 and a second mounting part 1030 for detachable connection with the graphics processor 3 and the chassis 4, respectively. The first frame 10 is configured to be positioned onto the chassis 4 via a first snap-fit ​​structure 11. By providing the mounting bracket 1 and the second mounting part 1030 on the first frame 10, the graphics processor 3 can be installed into the chassis 4 via the mounting bracket 1. Simultaneously, by providing the first snap-fit ​​structure 11, the graphics processor 3 and the mounting bracket 1 can be pre-positioned into the chassis 4 during installation, eliminating the need for continuous pressing of the graphics processor 3 by the operator, thus facilitating two-handed installation of the graphics processor 3.

[0042] Meanwhile, the second frame 20 includes a base plate 200, a gripping part 201 disposed on the base plate 200, and a locking part 204 disposed on the base plate 200. The second frame 20 is configured to be positioned on the graphics processor 3 and the mounting bracket 1 by engaging with the second snap-fit ​​structure 21 and the locking part 204. When the second frame 20 is positioned on the graphics processor 3 and the mounting bracket 1, the gripping part 201 is higher than the graphics processor 3 and the mounting bracket 1. By providing the docking bracket 2, the docking bracket 2 can be pre-positioned on the graphics processor 3 and the mounting bracket 1 using the second snap-fit ​​structure 21 and the locking part 204. Then, by holding the gripping part 201 on the docking bracket 2, the graphics processor 3 and the mounting bracket 1 can be moved to perform disassembly and assembly operations. Since the gripping part 201 is higher than the graphics processor 3 and the mounting bracket 1, it does not need to occupy the space of the graphics processor 3 in the front-back and left-right directions during disassembly and assembly operations, reducing the difficulty for operators to grasp, place, and press the graphics processor 3, and improving the convenience of disassembly and assembly operations.

[0043] In this embodiment, the grip portion 201 is generally rectangular in shape, and an opening is provided on the grip portion 201 for the palm to pass through so that the operator can grip and operate it. It is easy to understand that in other alternative embodiments, the grip portion 201 may also be configured with other shapes that are easy to grasp.

[0044] like Figure 1 and Figure 2 As shown, the first snap-fit ​​structure 11 in this embodiment includes a first slider 110 slidably disposed on the first frame 10 and a first elastic member 111 disposed between the first slider 110 and the first frame 10. The first slider 110 has a latch for fitting with the latching block 50 disposed on the chassis 4, and the first elastic member 111 applies pressure to the first slider 110 such that the latch tends to move away from the docking bracket 2. That is, during assembly, without any other external force, the first slider 110 will slide towards the side of the chassis 4 where the latching block 50 is located under the elastic force of the first elastic member 111.

[0045] Furthermore, in combination Figure 2 , Figure 9 , Figure 10 and Figure 11As shown, in this embodiment, the first slider 110 is provided with an upper locking plate 1100, a lower locking plate 1101, and a connecting plate 1102 disposed between the upper locking plate 1100 and the lower locking plate 1101. The upper locking plate 1100 and the lower locking plate 1101 are spaced apart and form the aforementioned locking slot between them, and the lower locking plate 1101 is provided with a guide slope for cooperating with the locking block 50 of the chassis 4. With the above structural design, when the graphics processor 3 is assembled, the graphics processor 3 and the mounting bracket 1 can be pressed down from top to bottom. The guide slope on the lower locking plate 1101 cooperates with the locking block 50 in the chassis 4 to press against it, which will cause the first slider 110 to be compressed and the first elastic element 111 to slide towards the docking bracket 2. Until the first slider 110 slides to the lower locking plate 1101 to avoid it, the mounting bracket 1 can continue to move down. As the mounting bracket 1 continues to move downwards until the lower locking plate 1101 is below the locking block 50, the first slider 110, driven by the first elastic element 111, slides further away from the docking bracket 2. This moves the lower locking plate 1101 below the locking block 50, while simultaneously moving the upper locking plate 1100 above the locking block 50, thus allowing the locking block 50 to engage with the slot formed between the upper locking plate 1100 and the lower locking plate 1101. When it is necessary to remove the graphics processor 3, the slot can be separated from the locking block 50 by pushing the first slider 110, thereby releasing the engagement and positioning of the first latching structure 11 and the locking block 50. Therefore, the above structural design simplifies the disassembly and assembly of the graphics processor 3 relative to the chassis 4.

[0046] The mounting bracket 1 in this embodiment further includes a connecting block 12, a limiting cover plate 13, and a limiting baffle 14. The connecting block 12 is fixedly installed on the first frame 10 and has a sliding groove 120. The limiting cover plate 13 is fixedly installed on the connecting block 12, and the limiting baffle 14 is perpendicular to the limiting cover plate 13. Specifically, in this embodiment, the limiting cover plate 13 and the limiting baffle 14 are integrally formed. In this embodiment, the limiting cover plate 13 covers the sliding groove 120 and has a sliding hole 130 corresponding to the sliding groove 120. The limiting baffle 14 has a through hole 140. The limiting cover plate 13 and the limiting baffle 14 are designed to cooperate with the first slider 110 in this embodiment to prevent the first slider 110 from disengaging from the sliding groove 120. Specifically, in this embodiment, the first slider 110 is slidably disposed in the slide groove 120, the first elastic element 111 is disposed between the first slider 110 and the inner wall of the slide groove 120, the lower retaining plate 1101 extends out of the slide groove 120, the connecting plate 1102 extends out of the slide groove 120 through the sliding hole 130, and the upper retaining plate 1100 passes through the through hole 140. In this way, the connection between the limiting cover plate 13 and the limiting baffle 14 can limit the connecting plate 1102 in the front-back direction, and the limiting cover plate 13 can also limit the first slider 110 in the up-down direction.

[0047] In addition, in this embodiment, a generally cylindrical support portion 141 is provided at the upper end of the limiting baffle 14, and the support portion 141 extends in the left-right direction. The support portion 141 is provided so that the operator can place his / her fingers when pushing the first slider 110, which facilitates the application of force to the first slider 110.

[0048] It should be noted that the directions such as "front", "rear", "left", "right", "up", and "down" in this embodiment are as follows: Figure 8 and Figure 9 As shown, the chassis 4 is placed normally and the graphics processor 3 is being assembled. The top and bottom of the chassis 4 along the height direction are defined as "up" and "down" respectively. The two ends of the mounting plate 5 inside the chassis 4 for mounting the graphics processor 3 along the length direction are defined as "left" and "right" respectively. The end of the graphics processor 3 closest to the mounting plate 5 is defined as "front" and the end of the graphics processor 3 closest to the mounting plate 5 is defined as "rear".

[0049] In addition, such as Figure 2 As shown, a limiting portion 131 extending beyond the edge of the connecting block 12 is formed at the end of the limiting cover plate 13 away from the limiting baffle 14. The limiting portion 131 is used to cooperate with the engaging portion 204. Figure 1 As shown, in this embodiment, a wire clamp 6 is also connected to the limiting part 131 by screws, and the wire clamp 6 is provided to facilitate wiring.

[0050] like Figure 5 As shown, in this embodiment, the first mounting portion 1000 is a connecting hole through which a screw passes, and the opening direction of the first mounting portion 1000 is the front-to-back direction. This allows a screw to be passed through the first mounting portion 1000 to lock and fix the mounting bracket 1 onto the graphics processor 3.

[0051] like Figure 3 and Figure 4 As shown, the second snap-fit ​​structure 21 in this embodiment includes a second slider 210 slidably disposed on the substrate 200 and a second elastic member 211 disposed between the second slider 210 and the substrate 200. The second slider 210 has a snap-fit ​​portion 2100 adapted to the slot 300 structure in the graphics processor 3. The second elastic member 211 applies pressure to the second slider 210 such that the snap-fit ​​portion 2100 tends to move away from the mounting bracket 1. Through the above structural design, the positioning of the docking bracket 2 with the graphics processor 3 and the mounting bracket 1 can be achieved using the snap-fit ​​portion 2100 and the engaging portion 204. At the same time, due to the design of the second slider 210 and the second elastic member 211, the ease of assembling and disassembling the docking bracket 2 with the graphics processor 3 and the mounting bracket 1 can be improved. Specifically, in combination with Figure 6 and Figure 7As shown, when assembling the docking bracket 2 with the mounting bracket 1 and the graphics processor 3, the engaging part 204 on the docking bracket 2 can be inserted below the limiting part 131 on the mounting bracket 1 to achieve engagement and positioning with the mounting bracket 1. Then, by pushing the second slider 210, the second slider 210 slides towards the side where the mounting bracket 1 is located to avoid it. After that, the end of the docking bracket 2 away from the mounting bracket 1 is pressed down so that the docking bracket 2 is completely attached to the upper surface of the graphics processor 3. The pushing operation on the second slider 210 is released, and the second slider 210 slides away from the mounting bracket 1 under the action of the second elastic member 211, so that the engaging part 2100 is engaged into the slot 300 on the graphics processor 3.

[0052] It should be noted that, as Figure 6 As shown, the card slot 300 described in this embodiment is formed by a control board 30 in the graphics processor 3 cooperating with the upper surface of the graphics processor 3. The control board 30 is an existing structure of the graphics processor 3, and only a protrusion needs to be formed at the end of the control board 30.

[0053] like Figure 3 and Figure 4 As shown, the mounting bracket 1 in this embodiment also includes a limiting structure mounted on the substrate 200. The limiting structure includes a limiting cover plate 22 and a limiting block 23. The limiting cover plate 22 is located on the other side of the second slider 210 relative to the substrate 200. The second slider 210 has an elongated hole 2101, and the limiting block 23 passes through the elongated hole 2101. The dimension of the limiting block 23 along the length of the elongated hole 2101 is smaller than that of the elongated hole 2101. That is, the limiting cover plate 22 is used to limit the second slider 210 in the left-right direction, and the limiting block 23 is used to limit the second slider 210 in the up-down and front-back directions. This prevents the second slider 210 from detaching from the substrate 200 and improves the sliding stability of the second slider 210. Furthermore, the limiting structure in this embodiment is detachably connected to the substrate 200 via the limiting block 23. Specifically, screws are used to pass through the substrate 200 and lock the substrate 200 and the limiting block 23 together.

[0054] In this embodiment, both the first elastic element 111 and the second elastic element 211 are compression springs. It is easy to understand that in other optional embodiments, the first elastic element 111 and the second elastic element 211 may also be made of elastic bodies such as metal elastics.

[0055] With the engagement portion 204 and the latching portion 2100 provided, the docking bracket 2 can maintain high stability with the mounting bracket 1 and the graphics processor 3 in the vertical and horizontal directions and the front-back direction. To further improve the connection stability between the docking bracket 2 and the graphics processor 3 and the mounting bracket 1, this embodiment further designs the second frame 20. Specifically, the second frame 20 in this embodiment also includes a left side plate 202 and a right side plate 203. The left side plate 202, the right side plate 203 and the grip portion 201 are all integrally formed with the substrate 200. Among them, the grip portion 201 is located above the substrate 200. The left side plate 202 and the right side plate 203 are arranged at intervals with the second latching structure 21 in the front-back direction and are located on the left and right sides of the substrate 200, respectively. The engagement portion 204 is formed on the left side plate 202 and the right side plate 203 at the end away from the second latching structure 21. With the above structural design, when the docking bracket 2, the graphics processor 3, and the mounting bracket 1 are assembled, the left side plate 202 and the right side plate 203 can be located on the left and right sides of the graphics processor 3, respectively, thereby limiting the connection from the left and right directions of the graphics processor 3 and improving the connection stability between the docking bracket 2, the graphics processor 3, and the mounting bracket 1.

[0056] As a second aspect of this application, this embodiment also provides a GPU server. For example... Figure 8 , Figure 9 and Figure 10 As shown, the GPU server includes a chassis 4, multiple graphics processors 3, and the aforementioned quick-release fixture. The chassis 4 houses a mounting plate 5 and has an opening through which the graphics processors 3 are mounted. The mounting bracket 1 in the quick-release fixture is detachably connected to the graphics processors 3 via a first mounting part 1000, and detachably connected to the mounting plate 5 via a second mounting part 1030. Specifically, in this embodiment, the second mounting part 1030 also has a connecting hole for screws to pass through, and the opening direction of the second mounting part 1030 is vertical. This allows screws to be passed through the second mounting part 1030 to lock and fix the mounting bracket 1 onto the mounting plate 5.

[0057] Furthermore, the aforementioned locking block 50 is disposed on the upper end surface of the mounting plate 5, and the mounting bracket 1 is engaged and positioned with the locking block 50 through the first snap-fit ​​structure 11. The specific operation process is as described above and will not be repeated here.

[0058] like Figure 2 and Figure 9As shown, in this embodiment, the upper surface of the mounting plate 5 is also provided with a slot 51 extending downward from the upper surface. The first frame 10 includes a first vertical plate 100, a second vertical plate 101, a first horizontal plate 102 disposed on the first vertical plate 100, and a second horizontal plate 103 disposed on the second vertical plate 101. The first vertical plate 100 and the second vertical plate 101 are perpendicular to each other. In this embodiment, the first snap-fit ​​structure 11 is disposed on the first horizontal plate 102. Specifically, the connecting block 12 in the first snap-fit ​​structure 11 is locked and fixed to the first horizontal plate 102 by screws. To improve the connection tightness between the two, in this embodiment, a gasket 15 is also provided on the side of the first horizontal plate 102 away from the connecting block 12.

[0059] In this embodiment, the first mounting part 1000 is disposed on the first vertical plate 100, and the second mounting part 1030 is disposed on the second horizontal plate 103. The second vertical plate 101 is inserted into the slot 51 when the first snap-fit ​​structure 11 engages with the snap-fit ​​block 50. This structural design not only further enhances the connection stability between the mounting bracket 1 and the mounting plate 5 through the insertion and engagement of the second vertical plate 101 and the slot 51, but also guides the downward pressing action of the mounting bracket 1 during assembly by inserting the second vertical plate 101 into the slot 51, preventing lateral deviation of the overall structure consisting of the docking bracket 2, the mounting bracket 1, and the graphics processor 3 during assembly.

[0060] Combination Figures 5 to 10 As shown, when it is necessary to install the graphics processor 3 onto the mounting plate 5 inside the chassis 4, the quick-release tooling is first assembled with the graphics processor 3. Specifically, the mounting bracket 1 is first fixed to the front end of the graphics processor 3 with screws. Then, the mounting bracket 2 is installed with the mounting bracket 1 and the graphics processor 3 through the snap-fit ​​part 2100, the engaging part 204, the left side plate 202, and the right side plate 203 on the docking bracket 2. Afterward, the operator operates the overall structure formed by the quick-release tooling and the graphics processor 3 by gripping the holding part 201. Specifically, the second vertical plate 101 on the mounting bracket 1 is aligned with the slot 51 on the mounting plate 5 and inserted. Then, the operator applies a downward pressing force to the docking bracket 2, which causes the locking block 50 on the mounting plate 5 to automatically engage with the slot on the mounting bracket 1. The force provided by the engagement between the mounting bracket 1 and the locking block 50 overcomes the elasticity of the blind-fit quick connector and keeps the graphics processor 3 stable relative to the chassis 4. Finally, screws are used to pass through the second horizontal plate 103 and lock it onto the mounting plate 5, thus completing the assembly of the graphics processor 3 and the chassis 4. Afterwards, the docking bracket 2 can be removed.

[0061] It should be noted that when the operator pushes the first slider 110, the operation can also be achieved by pulling back the part where the upper plate 1100 and the connecting plate 1102 are connected by the finger.

[0062] Combination Figure 2 , Figure 8 and Figure 11 As shown, when it is necessary to remove the graphics processor 3 from the chassis 4, the operator first installs the docking bracket 2 onto the graphics processor 3 and the mounting bracket 1, and then unscrews and removes the screws passing through the second mounting part 1030. Then, the operator grasps the holding part 201 with one hand, and with the other hand, the fingers rest on the support part 141 of the mounting bracket 1 and pushes the upper locking plate 1100, causing the first slider 110 to slide towards the docking bracket 2 until the locking tab on the first slider 110 separates from the locking block 50. Then, the operator can lift the graphics processor 3 and the mounting bracket 1 relative to the chassis 4 by grasping the holding part 201, thus completing the disassembly operation of the graphics processor 3.

[0063] like Figure 8 As shown, the spacing between adjacent graphics processors 3 is very small, and the spacing between the front and rear ends of graphics processors 3 and the inner wall of chassis 4 is also very small. The quick-assembly / disassembly fixture provided in this embodiment can utilize the space above the open end of chassis 4 for assembly operations. The operator can perform assembly / disassembly operations between the docking bracket 2 and mounting bracket 1 and graphics processor 3, as well as between the mounting bracket 1 and mounting plate 5, from above the graphics processor 3, mounting bracket 1, and mounting plate 5. The operator's hands do not need to occupy the space of the graphics processor 3 in the front-back, left-right, and right-side directions.

[0064] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art should understand that this application includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this application will be included within the scope of the claims.
