Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a modular combined server. Background Technology

[0002] In modular equipment or server assembly structures, multi-point positioning and mechanical locking are usually used to improve structural stability and installation accuracy in order to achieve precise docking and secure locking between components.

[0003] Currently, most existing upper and lower locating pins are machined from a single piece of metal, with a simple internal structure that relies solely on the insertion of a guide pin head into the locating hole to achieve mechanical engagement. While this structure provides basic positioning functionality, it has significant limitations when dealing with complex stress environments. Because the metal guide pin head and the mounting hole have rigid contact, they cannot absorb deformation caused by minor mechanical impacts or temperature changes, leading to wear and increased clearances after prolonged use, thus reducing the assembly accuracy of the structure.

[0004] In summary, the existing technology has a technical problem: due to the simple structure of the upper and lower positioning pins, it is difficult to maintain the positioning accuracy during equipment assembly, resulting in the inability to self-lock to resist vibration, which further affects the load-bearing stability of the modular system. Summary of the Invention

The lock seat is fixedly installed in the second front and rear locking mounting steps of the rear module of the chassis; and a first locking handle, which is a T-shaped rotary structure with a first threaded hole in the middle and a fan-shaped cam surface at the bottom. After the first locking handle is installed on the first stud of the fixed base through the first threaded hole, rotating the first locking handle causes the cam surface to move downward and press the lock seat, so that the second limiting slope and the first limiting slope are pressed together, thereby locking the front module and the rear module of the chassis.

Detailed Implementation

[0021] This application provides a modular combined server that solves the technical problem in the prior art where the simple structure of the upper and lower positioning pins makes it difficult to maintain positioning accuracy during equipment assembly, resulting in the inability to self-lock to resist vibration and further affecting the load-bearing stability of the modular system. By setting upper and lower positioning pins with rotating structures and flexible buffer components, the technical goal of high-precision adaptive positioning of multi-module chassis in the longitudinal and lateral directions is achieved. This effectively reduces assembly errors in complex operating environments and improves structural locking strength and overall shock and vibration resistance.

[0022] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. It should be understood that this application is not limited to the exemplary embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. It should also be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all of them.

[0023] Example 1, please refer to Figure 1 This application provides a modular combined server, specifically including: The front module 1 of the chassis has a first upper and lower positioning pin hole 101 at the front, upper and lower locking mounting steps 102 and a first front and rear locking mounting steps 103 at the middle of both sides, and a front and rear positioning pin hole 104 arranged non-collinearly at the rear end.

[0024] Specifically, such as Figure 19 As shown, the front module 1 of the chassis is the front structural unit of the modular combined server shell, used to carry the electronic components, interfaces and heat dissipation devices inside the server, and together with the rear module of the chassis, it forms a complete chassis frame. The front of the front module 1 is provided with first upper and lower positioning pin holes 101 for inserting front and rear positioning pins 203 to ensure the assembly accuracy in the vertical direction and the stability when the modules are stacked.

[0025] On both sides of the center of the front module 1 of the chassis, there are vertical locking mounting steps 102 and first front-rear locking mounting steps 103. The vertical locking mounting steps 102 are step structures for installing vertical locking devices, providing a mounting reference for the locking components when the server modules are stacked vertically. The first front-rear locking mounting steps 103 are used for installing front-rear locking components, allowing the front module 1 of the chassis to be tightly connected to the rear module 2 of the chassis. The step structure is used to form a flat and precise mounting surface, so that the locking components are evenly stressed and stress concentration is prevented at the connection.

[0026] On the rear end face of the front module 1 of the chassis, there are also front and rear positioning pin holes 104 arranged non-collinearly. The non-collinear arrangement means that the front and rear positioning pin holes 104 are not located on the same straight line in space, but are staggered at a certain angle or interval to achieve higher positioning accuracy and structural stability, prevent the two modules from rotating and shifting during assembly, and ensure the parallelism and overall rigidity of the front and rear modules after connection.

[0027] The rear module 2 of the chassis has front and rear positioning pins 203 arranged non-collinearly on its front end face, second front and rear locking mounting steps 202 on both sides of the front, and second upper and lower positioning pin holes 201 at the rear.

[0028] Specifically, such as Figure 19 and Figure 20 As shown, the rear module 2 of the chassis is the rear unit of the server chassis structure, used to install the motherboard interface, power supply, fan and various external connection ports, and together with the front module 1 of the chassis, it forms a complete modular shell structure.

[0029] The front face of the rear module 2 of the chassis is provided with non-collinearly arranged front and rear locating pins 203, which are metal guides used to achieve precise docking between the front and rear modules of the chassis. The non-collinear arrangement means that the front and rear locating pins 203 are staggered in space, rather than arranged in a straight line, to prevent the modules from rotating during assembly, thereby improving assembly accuracy and overall stability.

[0030] Second front and rear locking mounting steps 202 are provided on both sides of the front of the rear module 2 of the chassis. These steps are used for mounting locking components in the front and rear directions, allowing the front module 1 and the rear module 2 of the chassis to be mechanically fixed together. The step structure provides a precise mounting plane, ensuring that the locking components are evenly stressed when tightened or pressed, preventing local deformation or loosening, and improving the shock resistance and durability of the connection.

[0031] A second upper and lower positioning pin hole 201 is provided at the rear of the rear module 2 of the chassis. When multiple server modules are stacked, it is used to insert a positioning structure to achieve vertical positioning and fixation. Through the second upper and lower positioning pin hole 201, modules at different levels can maintain vertical alignment and prevent displacement and loosening caused by weight or vibration.

[0032] The front and rear locking components 4 are located at the first front and rear locking mounting steps 103 and the second front and rear locking mounting steps 202. After the front module 1 and the rear module 2 of the chassis are positioned and engaged by the front and rear positioning pins 203 and the front and rear positioning pin holes 104, the front and rear locking components 4 lock the front module 1 and the rear module 2 of the chassis.

[0033] Specifically, such as Figure 2 , Figure 19 and Figure 20 As shown, the front and rear locking components 4 are mechanical locking devices used to securely connect the front module 1 and the rear module 2 of the chassis together. They provide stable structural fixation after the modules are positioned, preventing loosening or displacement due to vibration during transportation or operation. The front and rear locking components 4 are located at the first front and rear locking mounting steps 103 and the second front and rear locking mounting steps 202, which are the mounting step areas reserved at the corresponding positions of the front and rear modules.

[0034] After the front module 1 and rear module 2 of the chassis are aligned using the front and rear locating pins 203 and the front and rear locating pin holes 104, the front and rear locking components 4 begin to function. The front and rear locating pins 203 are metal guide posts installed on the rear module 2, while the front and rear locating pin holes 104 are corresponding slots on the front module 1. When the two are inserted, they ensure accurate positioning of the two modules in three dimensions. After positioning, the front and rear locking components 4 perform a locking operation by tightening, pressing, or snapping, forming a mechanical connection between the two modules in the front-rear direction, thereby achieving structural fixation and load transfer of the overall chassis.

[0035] The upper and lower locking components 3 are installed inside the upper and lower locking mounting steps 102. After multiple front and rear assembled chassis modules are positioned and engaged by the upper and lower positioning pins 5 through the first upper and lower positioning pin holes 101 and the second upper and lower positioning pin holes 201 respectively, the upper and lower locking components 3 perform longitudinal stacking locking.

[0036] Specifically, such as Figure 2 and Figure 19 As shown, the upper and lower locking components 3 are mechanical structural parts used to achieve vertical stacking and fixation of the chassis modules. They provide a stable longitudinal connection between multiple chassis modules assembled front and back, allowing the overall server system to be stacked in multiple layers in space while maintaining structural stability. The upper and lower locking components 3 are set within the upper and lower locking mounting steps 102, thereby installing and supporting the locking components. This ensures that the upper and lower locking components 3 are subjected to uniform force and remain flat during operation, thus preventing displacement or tilting of the chassis during stacking.

[0037] During stacking, multiple chassis modules that have completed front-to-back assembly need to be aligned using upper and lower locating pins 5. The upper and lower locating pins 5 are guide elements for precise vertical positioning. Made of metal, each pin's end can be inserted into the first upper and lower locating pin hole 101 of the upper module and the second upper and lower locating pin hole 201 of the lower module, respectively, thus achieving precise docking between modules. The first upper and lower locating pin hole 101 is located at the bottom of the upper module, while the second upper and lower locating pin hole 201 is located at the top of the lower module. Their cooperation ensures a unique assembly direction and accurate positioning.

[0038] Once vertical alignment is complete, the upper and lower locking components 3 begin to lock, that is, by rotating, pressing or snapping, the upper and lower modules are fixed together to form a longitudinal stacked locking structure. This not only prevents the modules from loosening due to vibration or airflow during operation, but also improves the overall frame's compressive strength and load-bearing capacity.

[0039] Furthermore, this application also includes: a fixed base 401, which is a square frame structure, with a first stud 405 in the middle of the fixed base 401 and a first limiting inclined surface 4014 on one side of the fixed base 401. After being positioned by a positioning pin 4015, the fixed base 401 is fixedly installed in the first front and rear locking mounting steps 103 of the front module 1 of the chassis; and a lock seat 404, which is provided with a second limiting inclined surface 4041 with an outwardly extending inclined surface structure and a flat base 4042. The lock seat 404 is fixedly installed in the second front and rear locking mounting steps 103 of the rear module 2 of the chassis. The first locking handle 402 is installed inside the rear locking step 202. The first locking handle 402 is a T-shaped rotary structure with a first threaded hole 4021 in the middle and a fan-shaped cam surface 4024 at the bottom. After the first locking handle 402 is installed on the first stud 405 of the fixed base 401 through the first threaded hole 4021, the cam surface 4024 moves downward to press the locking seat 404 by rotating the first locking handle 402, so that the second limiting inclined surface 4041 and the first limiting inclined surface 4014 are pressed together, thereby locking the front module 1 and the rear module 2 of the chassis.

[0040] Specifically, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the fixed base 401 is the basic load-bearing component in the front and rear locking mechanism, providing installation support and rotation reference for the entire locking system. Because the square frame structure has good stress uniformity and installation stability, ensuring that the locking components do not deform under high-frequency operation or pressure, the fixed base 401 adopts a square frame structure. A first stud 405 is provided in the middle of the fixed base 401, which is a metal shaft for mounting the rotating components, serving to support and transmit rotational torque. A first limiting inclined surface 4014 is provided on one side of the fixed base 401, used to cooperate with another limiting surface in the locking mechanism to ensure positioning accuracy and clamping effect during rotational locking. After being calibrated by the positioning pin 4015, the fixed base 401 is fixedly installed within the first front and rear locking mounting steps 103 of the front module 1 of the chassis, thereby ensuring accurate installation position and a flat force-bearing surface, thus achieving a stable foundation for the front and rear locking structure.

[0041] The lock seat 404 is a component that works with the fixed base 401 to achieve the locking function. Structurally, it includes a second limiting inclined surface 4041 with an outwardly extending inclined structure and a flat base 4042. The second limiting inclined surface 4041 corresponds to the first limiting inclined surface 4014 on the fixed base 401 and is used to form mutually pressing contact surfaces during the locking process. The axial locking force is generated by the inclined surface pressing, ensuring a seamless fit between the front and rear modules. The flat base 4042 provides mounting support, allowing the lock seat 404 to be securely fixed within the second front and rear locking mounting steps 202 of the rear module 2 of the chassis.

[0042] The first locking handle 402 adopts a T-shaped rotary structure, which has a horizontal gripping rod and a vertical rotating shaft in its shape, allowing the operator to easily lock the device by rotating it. A first threaded hole 4021 is provided in the middle of the first locking handle 402 for threaded connection with the first stud 405 on the fixed base 401, thus forming a rotatable connection. A fan-shaped cam surface 4024 is provided at the bottom of the first locking handle 402 for performing the locking action. By rotating the first locking handle 402, the cam surface 4024 will displace downwards in the direction of rotation, thereby applying a compressive force to the lock seat 404 below. At this time, the second limiting inclined surface 4041 and the first limiting inclined surface 4014 abut against each other, generating a strong clamping force, thereby achieving a tight lock between the front module 1 and the rear module 2 of the chassis.

[0043] Furthermore, this application also includes: an annular structure is provided on the other side of the fixed base 401. The two ends of the annular structure are straight sliding inclined surfaces 4011, the middle is a circular sliding inclined surface 4012, and a limiting notch 4013 is provided in the center. Multiple operating concave surfaces 4022 are provided at the circular position of the head of the first locking handle 402. A plunger pin hole 4023 is provided on one side of the first locking handle 402 to accommodate the second plunger pin 403. When the locking operation needs to be performed, the first locking handle 402 is rotated by pinching the operating concave surface 4022, which drives the head of the second plunger pin 403 to enter from the sliding inclined surface 4011 and slide on the sliding inclined surface 4012. After the second plunger pin 403 enters the limiting notch 4013, it completes the anti-rotation of the first locking handle 402. At this time, the cam surface 4024 presses the lock seat 404, so that the second limiting inclined surface 4041 and the first limiting inclined surface 4014 are pressed together to complete the locking.

[0044] Specifically, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, the fixed base 401 is the basic support component of the locking structure, providing a stable installation platform for the subsequent locking mechanism. A ring-shaped structure, made of metal, is provided on one side of the fixed base 401. The ring layout ensures uniform force distribution and rotational balance. The two ends of the ring structure are designed as straight-curved sliding ramps 4011, facilitating the smooth entry of the second plunger pin 403, reducing screwing resistance, and ensuring the guiding accuracy of the structure during the initial locking phase. The middle part of the ring structure is a circular sliding ramp 4012, which guides the second plunger pin 403 during rotation, ensuring smooth force transmission and reducing jamming during the rotation of the first locking handle 402. The central limiting notch 4013 is used to position and prevent the second plunger pin 403 from rotating to a specific angle, thereby achieving mechanical fixation of the first locking handle 402 in the locked position.

[0045] The head of the first locking handle 402 has multiple operating concave surfaces 4022, which facilitate manual pinching by the operator during locking or unlocking, increasing the force-bearing area and improving operational comfort and friction. A plunger pin hole 4023 is provided on one side of the first locking handle 402 to accommodate the second plunger pin 403, ensuring it moves along a predetermined trajectory during rotation. The second plunger pin 403 is a key transmission element for achieving mechanical locking. During operation, it slides along the inclined plane 4011 into the annular structure and moves along the sliding inclined plane 4012 until it enters the limiting notch 4013. At this point, the rotation of the first locking handle 402 is stopped, completing the locking action. A cam surface 4024 is located at the other end of the locking first locking handle 402. When the first locking handle 402 rotates, it generates a compressive force, pushing the lock seat 404 to displace.

[0046] The locking seat 404 is a component used to achieve mechanical clamping. It has a second limiting inclined surface 4041, which is opposite to the first limiting inclined surface 4014 on the fixed base 401. When the cam surface 4024 presses against the locking seat 404, the second limiting inclined surface 4041 and the first limiting inclined surface 4014 are forced to press together, thereby putting the entire mechanism in a fully locked state and preventing the chassis module from loosening under vibration or external force.

[0047] Furthermore, this application also includes: after the fixed base 401, lock seat 404, and first locking handle 402 are locked, they form a flat plate structure without protrusions.

[0048] Specifically, such as Figure 17 and Figure 18As shown, the fixed base 401 is the supporting foundation of the entire locking device, fixed to the main structure of the equipment or chassis, providing stable support and installation position for the locking mechanism. The fixed base 401 adopts a planar structure to ensure a continuous appearance interface with other components after locking, thereby improving the flatness and sealing of the overall structure. The lock seat 404 is a clamping component that cooperates with the fixed base 401. During the locking process, it achieves a clamping effect through mechanical transmission with the first locking handle 402. Its position, when in contact with the base, effectively avoids local protrusion and ensures the consistency of the structural appearance. The first locking handle 402 is the main operating component for performing the locking action. After rotation locking is completed, its surface forms a plane with the base and lock seat at the same height, with no obvious protrusions or depressions visible from the outside.

[0049] Furthermore, this application also includes: a mounting frame 301, which is a square frame structure, a second stud 3011 is provided on the central crossbeam of the mounting frame 301, and multiple through-hole locking pin holes 3012 are provided on the left and right sides of the mounting frame 301; a locking pin seat 302, which is a long strip structure, a third limiting inclined surface 3021 is provided at the center of the locking pin seat 302, and multiple locking pin holes 3023 are arranged in the length direction of the locking pin seat 302, with locking pins 304 provided in the locking pin holes 3023; and a second locking handle 303, which is a T-shaped rotating structure, and a second... The top of the locking handle 303 is provided with an annular inclined surface 3031 that mates with the third limiting inclined surface 3021, and the center of the second locking handle 303 is provided with a second threaded hole 3032. When performing longitudinal stacking locking, the mounting frame 301 is placed inside the upper and lower locking mounting steps 102, and after the two locking pin seats 302 are installed on the mounting frame 301, the second locking handle 303 is screwed in. During the screwing process, the annular inclined surface 3031 presses the third limiting inclined surface 3021 to limit and lock, so that the locking pin seat 302 is in the first position. At this time, the locking pin 304 passes through the locking pin hole 3023 and the through hole locking pin hole 3012 and mates with the front module 1 of the chassis to complete the locking.

[0050] Specifically, such as Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the mounting frame 301 is a structural component that serves as a load-bearing and connecting element. Its square frame design provides a stable mounting reference for the upper and lower modules. The square frame shape ensures a more uniform stress distribution, thereby improving the overall structural rigidity and resistance to deformation. A second stud 3011 on the central crossbeam of the mounting frame 301 is used to install or fix other locking elements, such as locking handles or threaded connections. Its central position facilitates the application of symmetrical locking forces. Multiple through-hole locking pin holes 3012 on the left and right sides of the mounting frame 301 accommodate locking pins 304, enabling reliable mechanical connection and positioning between modules.

[0051] The locking pin seat 302 is a structural component used to cooperate with the mounting frame 301 and realize the movement and limitation of the locking pin 304. The locking pin seat 302 has an elongated structure, which facilitates the arrangement of multiple locking pin holes 3023 along its length to meet different installation requirements. The third limiting inclined surface 3021 at the center of the locking pin seat 302 is used to cooperate with the annular inclined surface 3031 of the second locking handle 303, thereby realizing force transmission and limit control. The locking pin 304 is provided in the locking pin hole 3023 inside the locking pin seat 302. The locking pin 304 is a flexible positioning element that can switch between locked and released states when rotated or pushed, so that the structure has a repeatable locking function.

[0052] The second locking handle 303 is the actuating component, featuring a T-shaped rotating structure for easy manual rotation and force application. The annular inclined surface 3031 at the top engages with the third limiting inclined surface 3021 of the locking pin seat 302, achieving longitudinal compression and locking through rotational motion. The second threaded hole 3032 at the center of the second locking handle 303 engages with the central stud 3011 of the mounting frame 301, forming a screw-in connection, thus converting the rotational motion into axial pressure. During longitudinal stacking locking, the mounting frame 301 is placed within the upper and lower locking mounting steps 102, positioning it with the chassis module. Two locking pin seats 302 are installed, and the second locking handle 303 is screwed in. During rotation, the annular inclined surface 3031 gradually compresses the third limiting inclined surface 3021, forcing the locking pin seat 302 to the first position. In this state, the locking pin 304 penetrates the locking pin hole 3023 and the through-hole locking pin hole 3012, ultimately engaging tightly with the front module 1 of the chassis to complete the locking action.

[0053] Furthermore, this application also includes: an operating ring 3022 is provided on the locking pin seat 302. When it is necessary to perform vertical stacking unlocking, the second locking handle 303 is rotated out and the operating ring 3022 is pulled so that the locking pin seat 302 is in the second position. At this time, the locking pin 304 exits from the through hole locking pin hole 3012 and is released from locking with the front module 1 of the chassis.

[0054] Specifically, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the operating ring 3022 on the locking pin seat 302 is a structural component for manual force application. It has a ring or semi-ring shape, facilitating hooking operation with fingers or tools. It assists in moving the locking pin seat 302, allowing it to switch positions in the longitudinal direction, thereby achieving the transition between locked and unlocked states. Since the locking pin seat 302 contains a first plunger pin 305, the operating ring 3022 can overcome elasticity or friction, precisely controlling its sliding.

[0055] When longitudinal stacking unlocking is required, the second locking handle 303 is unscrewed, that is, by rotating in the opposite direction, the originally pressed annular inclined surface 3031 is disengaged from the third limiting inclined surface 3021, thereby releasing the axial pressure. This releases the locking state and prevents structural obstruction or damage when the locking pin seat 302 is pulled subsequently.

[0056] Next, by pulling the operating ring 3022, the locking pin seat 302 can be moved along the preset guide rail direction, switching the locking pin seat 302 from the original first position to the second position. The first position corresponds to the locked state, that is, the locking pin 304 passes through the through-hole locking pin hole 3012 and connects to the front module 1 of the chassis; the second position corresponds to the unlocked state, that is, the locking pin 304 exits the through-hole locking pin hole 3012, thereby achieving separation. This process requires controlling the pulling distance and direction to ensure that the locking pin 304 is completely exited without damaging the hole wall. The locking pin 304 is a cylindrical metal component made of high-strength steel, responsible for bearing the shear force and axial load between the modules in the locked state. After it exits the through-hole, there is no longer a mechanical constraint between the two modules, and they can be freely separated or reinstalled.

[0057] Furthermore, this application also includes: four S-shaped sliding grooves 3013 are provided on one side of the upper and lower ends of the mounting frame 301, and two first plunger pins 305 are provided on the locking pin seat 302. When the locking pin seat 302 is in the first position or the second position, the first plunger pins 305 cooperate with the S-shaped sliding grooves 3013 to perform positioning.

[0058] Specifically, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, four S-shaped grooves 3013 are provided on one side of each of the upper and lower ends of the mounting frame 301, indicating that a total of four S-shaped groove structures are arranged on the upper and lower edges of the mounting frame. The S-shaped groove 3013 is a guide groove with an arc transition and multiple curvature changes, used to achieve smooth guidance and precise limit control through a curved trajectory. Compared with straight grooves, the S-shaped groove 3013 can provide a longer motion path and a smoother displacement transition within a limited space, thereby reducing mechanical impact and improving structural stability.

[0059] The locking pin seat 302 is equipped with two first plunger pins 305, indicating that two plunger structures with elastic positioning functions are arranged on the side of the elongated locking pin seat 302. The first plunger pin 305 is a small cylindrical pin with a spring loading mechanism; one end is a retractable head, and the other end generates continuous thrust through a spring, used for automatic positioning and stopping in mechanical engagement. The arrangement of the two first plunger pins 305 allows the locking pin seat 302 to simultaneously form a double-point limit with the upper and lower sliding grooves during longitudinal sliding, thereby improving structural stability and vibration resistance.

[0060] When the locking pin seat 302 is in the first or second position, the first plunger pin 305 cooperates with the S-shaped slide groove 3013 to perform positioning, meaning that the entire positioning process relies on the interlocking between the head of the first plunger pin 305 and the curved structure inside the S-shaped slide groove 3013. In the first position, i.e., the locked state, the first plunger pin 305 will engage with the front arc-shaped recess of the S-shaped slide groove 3013, playing a locking and limiting role; while in the second position, i.e., the unlocked state, the first plunger pin 305 will slide into the rear recess of the S-shaped slide groove 3013, forming a new stable support point.

[0061] Furthermore, this application also includes: a plurality of tool holes 3033 for inserting auxiliary tools are provided on the circular surface of the second locking handle 303.

[0062] Specifically, such as Figure 8 As shown, the circular surface of the second locking handle 303 is provided with multiple tool holes 3033 for inserting auxiliary tools. This allows the operator to perform rotation or disassembly operations using external auxiliary tools when space is limited or manual operation is difficult. The second locking handle 303 is a T-shaped rotating component used to control the opening and closing of the locking mechanism through rotation. Its circular surface corresponds to the outer edge of the handle and is the key contact surface for transmitting torque. The tool holes 3033 are equivalent to the points of external force application, distributed in a circular or elliptical shape. The hole diameter is determined according to the handle size, generally between 3 mm and 5 mm, allowing the insertion of standard L-shaped wrenches, locating pins, or operating levers, thereby achieving the effect of mechanically amplifying torque.

[0063] Auxiliary tools are external tools that help operators apply greater rotational force, such as Allen wrenches, small lever handles, or specially designed locking levers. When the handle is installed deep inside a module or obstructed by adjacent structures, it is difficult to rotate directly with fingers. In this case, an auxiliary tool can be inserted into the tool hole to increase torque through leverage, making rotation easier and more precise.

[0064] Furthermore, this application also includes: after the second locking handle 303 is locked and engaged with the mounting frame 301, it forms a flat plate structure without protrusions.

[0065] Specifically, such as Figure 3 and Figure 9 As shown, after the second locking handle 303 locks into the mounting frame 301, a flat, non-protruding structure is formed. This means that after the locking operation is completed, the surface of the second locking handle 303 and the outer surface of the mounting frame 301 are on the same plane, resulting in a smooth, flat, plate-like structure without any protrusions. This non-protruding flat structure optimizes the stacking and space utilization efficiency of server modules. Since modular servers use a multi-layer stacking method with small spacing between layers, if the locking handle protrudes above the surface, it may cause interference between adjacent modules, increasing assembly difficulty and affecting heat dissipation performance. By designing the second locking handle 303 flush with the mounting frame 301, mechanical interference is avoided, and the modules fit more tightly, improving space utilization. Furthermore, the flat structure effectively reduces dust accumulation and the risk of external collisions. Protruding structures easily become accumulation points for dust and impurities and may deform due to collisions during maintenance or handling; while a flat surface makes wiping and maintenance more convenient, while maintaining the integrity and damage resistance of the shape during transportation.

[0066] Furthermore, this application also includes: the upper and lower positioning pins 5 are rotary structures, including two guide pin heads 501, soft pads 502 and a dividing step 503, which is composed of two annular soft pads 502 attached to the upper and lower parts of the dividing step 503.

[0067] Specifically, such as Figure 21As shown, the upper and lower positioning pins 5 are structural components used for installing and fixing parts. They feature a rotary structure, meaning they can rotate around a certain axis, thus providing flexible positioning during installation or adjustment. The upper and lower positioning pins 5 consist of two guide pin heads 501, a soft pad 502, and a separating step 503. The guide pin heads 501 are cylindrical parts for insertion, serving to accurately align and prevent misalignment; the two guide pin heads 501 are located at the upper and lower ends, allowing the upper and lower positioning pins 5 to provide support and positioning functions simultaneously in the vertical direction. The soft pad 502 is an elastic material layer made of rubber, silicone, or polyurethane, used to absorb minor deformations between contact surfaces, mitigate impacts, or prevent direct friction between metal parts, thereby improving stability and extending service life. The separating step 503 is a protruding structure in the middle of the upper and lower positioning pins 5, used to separate the structural space between the two guide pin heads 501, while also providing a support surface for the soft pad 502. This allows the two annular soft pads 502 to be evenly distributed on the upper and lower sides of the separating step, ensuring the symmetry and balance of the upper and lower positioning pins 5 under force.

[0068] In summary, the modular combined server provided in this application has the following technical effects: by setting up upper and lower positioning pins with rotating structures and flexible buffer components, the technical goal of high-precision adaptive positioning of multi-module chassis in the longitudinal and lateral directions is achieved, thereby effectively reducing assembly errors in complex operating environments and improving structural locking strength and overall shock and vibration resistance.
