Abstract
Description
Technical Field
[0001] This application relates to the field of server technology, and in particular to locking structures and servers having the same. Background Technology
[0002] Currently, in the heat dissipation solutions of high-density electronic devices, such as data center servers, a common design is to use a locking structure with elastic elements to connect the heat sink and the heat source. This design allows the heat sink to maintain good contact with the heat source during thermal expansion and contraction, thereby effectively improving heat dissipation efficiency. In specific implementations, the locking structure typically includes a screw, a spring, and a stud or sleeve. The screw passes through through holes in both the heat sink and the heat source, the spring is positioned between them to provide the necessary elastic pressure, and the stud or sleeve is responsible for fixing the position of the spring and the screw. This design, to some extent, solves the problem of mechanical stress caused by temperature changes, enabling the heat sink to maintain its function under various operating conditions.
[0003] However, despite its functional performance, this design reveals a critical weakness during actual manufacturing and transportation: when the locking structure is not fully locked, the elastic element may partially or completely protrude from the locking hole, posing a serious hazard during the transportation and installation of electronic equipment. Since servers and other high-precision electronic devices may experience severe vibrations or collisions during logistics, the spring protruding from the locking hole is highly susceptible to deformation, twisting, or even breakage due to external forces. This can lead to the failure of the heat sink's locking function, severely impacting the device's heat dissipation performance and stability. Furthermore, the external nature of the spring necessitates careful handling during each assembly to prevent it from getting stuck or damaged during insertion, increasing assembly difficulty and time costs.

[0005] This application provides a locking structure for connecting a component to be installed and a foundation to be fixed.

[0006] Furthermore, the locking pin also includes a first positioning step to divide the locking hole into a first hole section near the opening of the locking hole and a second hole section away from the opening. An external thread section is disposed in the second hole section, and an elastic element is disposed in the first hole section. One end of the elastic element abuts against the first positioning step, and the other end of the elastic element abuts against the locking element.
[0007] Furthermore, the locking member includes a main body and a second positioning step that are connected to each other. The second positioning step protrudes from the outer periphery of the main body and is disposed opposite to the first positioning step. The second positioning step is used to be inserted into at least a portion of the locking hole, and the other end of the elastic member abuts against the second positioning step.
[0008] Furthermore, the sidewall of the first positioning step and the sidewall of the first hole section are arranged at radial intervals along the locking hole; Wherein, the elastic element is a spring, and the gap between the sidewall of the first positioning step and the sidewall of the first hole section is smaller than the wire diameter of the spring; and / or, The radial gap between the sidewall of the first positioning step and the sidewall of the first hole section along the locking hole is L, where 0 < L < 0.3 mm.

[0021] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] The embodiments of this application provide a locking structure, and the device is described in detail in conjunction with the structure and working principle of the locking structure.
[0023] like Figures 1 to 6 As shown, one aspect of this application provides a locking structure for connecting a component to be installed and a foundation to be fixed, including a locking post 200, a locking member 100, and an elastic member 300. The locking post 200 is installed on the component to be installed and has a locking hole 201. At least a portion of the locking member 100 is movably disposed within the locking hole 201 and has an external thread section 101. The foundation to be fixed has a first internal thread section adapted to the external thread section 101, so as to connect with the external thread section through the first internal thread section. The engagement of the threaded section 101 allows the locking member 100 to pass through the locking hole 201 and be locked to the foundation to be fixed; the elastic member 300 is telescopically disposed within the locking hole 201, with one end of the elastic member 300 abutting against the locking post 200 and the other end of the elastic member 300 abutting against the locking member 100; wherein, the elastic member 300 has a deformed state and an initial state; when the elastic member 300 is in the initial state, at least a portion of the locking member 100 is disposed within the locking hole 201, so that the elastic member 300 is entirely located within the locking hole 201.
[0024] The locking structure provided in this application embodiment, by setting elastic members 300 with both ends abutting against the locking hole 201 and the locking post 200 respectively, and by setting at least a portion of the locking member 100 in the locking hole 201 when the elastic member 300 is in the initial state, solves the technical problem that the elastic member protrudes from the locking hole when the locking structure is not locked, which makes it easy to be damaged during transportation, and achieves the technical effect of improving transportation safety.
[0025] In the above embodiments, the locking pin 200 is installed on the part to be installed, and the locking hole 201 not only provides a place for the locking member 100 and the elastic member 300, but its structural design is also the key to realizing the function of the elastic member 300 being concealed and the locking structure. Figure 2As shown, the locking element 100 is partially movably disposed within the locking hole 201. The presence of the external thread section 101, in conjunction with the first internal thread section on the foundation to be fixed, forms the basis of the mechanical connection, allowing the locking element 100 to pass through the locking hole 201 and form a firm connection with the foundation to be fixed. Simultaneously, the locking element 100 abuts against one end of the elastic element 300, utilizing the elastic force of the elastic element 300 to assist the locking process, ensuring the reliability and stability of the connection. The elastic element 300 is retractably disposed within the locking hole 201, with one end abutting against the locking pin 200 and the other end abutting against the locking element 100. It transitions between a deformed state and an initial state. In the initial state, it ensures that a portion of the locking element 100 is always placed within the locking hole 201, thus completely concealing the elastic element 300 within the locking hole 201, avoiding the risk of exposure during transportation and pre-assembly.
[0026] Specifically, the locking post 200 also includes a first positioning step 210 to divide the locking hole 201 into a first hole segment 201a near the opening of the locking hole 201 and a second hole segment 201b away from the opening. An external thread segment 101 is disposed within the second hole segment 201b, and an elastic element 300 is disposed within the first hole segment 201a. One end of the elastic element 300 abuts against the first positioning step 210, and the other end of the elastic element 300 abuts against the locking element 100. The first positioning step 210 on the locking post 200 divides the locking hole 201 into the first hole segment 201a and the second hole segment 201b. On the one hand, this provides physical support for one end of the elastic element 300, ensuring its positional stability; on the other hand, through its distance relationship with the second hole segment 201b, it implicitly defines the range of motion of the locking element 100, thereby indirectly controlling the working range of the elastic element 300.
[0027] The external thread section 101 is located within the second hole section 201b, maintaining an appropriate distance from the locking hole 201 in the depth direction. This avoids unnecessary resistance caused by direct contact and also provides necessary deformation space for the elastic element 300. When the locking element 100 rotates in conjunction with the first internal thread section on the foundation to be fixed, the external thread section 101 moves along the path of the locking hole 201 until it fully engages with the first internal thread section, completing the locking process.
[0028] The elastic element 300 is precisely placed within the first hole section 201a, with one end abutting the first positioning step 210 and the other end contacting the locking element 100. This arrangement ensures the stability of the elastic element 300 within the locking structure. Simultaneously, its complete concealment within the locking hole 201 prevents exposure during incomplete locking, effectively protecting the elastic element 300 from external environmental damage. During the rotation of the locking element 100 to the locked state, the elastic element 300 provides necessary elastic support through its contact with both ends against the first positioning step 210 and the locking element 100, helping to tightly engage the locking element 100 with the first internal thread section, enhancing the stability and reliability of the connection. In summary, the introduction of the first positioning step 210 optimizes the positioning of the locking element 100 and the elastic element 300 within the locking hole 201, effectively preventing the elastic element 300 from being exposed, while ensuring a precise and reliable connection between the locking element 100 and the foundation to be fixed.
[0029] Specifically, the locking member 100 includes a main body 110 and a second positioning step 120 connected to each other. The second positioning step 120 protrudes from the outer periphery of the main body 110 and is disposed opposite to the first positioning step 210. The second positioning step 120 is used for insertion into at least a portion of the locking hole 201, and the other end of the elastic member 300 abuts against the second positioning step 120. The design shape and size of the main body ensure smooth and unobstructed passage through the locking hole 201 and the second positioning step 120. The second positioning step 120 protrudes from the outer periphery of the main body 110 and is used for positioning the elastic member 300 within the locking hole 201, preventing the elastic member 300 from protruding from the locking hole 201. The second positioning step 120 and the first positioning step 210 form a stable limiting structure, ensuring that the elastic member 300 will not be misaligned or shifted during the locking process. One end of the elastic element 300 abuts against the first positioning step 210, and the other end abuts against the second positioning step 120. This arrangement ensures the positioning accuracy and stability of the elastic element 300 during elastic loading and release. The contact between the elastic element 300 and the second positioning step 120 not only provides physical support for it but also provides necessary elastic feedback for the locking element 100, promoting effective engagement between the locking element 100 and the first internal thread section, thereby strengthening the connection between the part to be installed and the foundation to be fixed.
[0030] Specifically, the sidewall of the first positioning step 210 and the sidewall of the first hole segment 201a are radially spaced apart along the locking hole 201. The elastic element 300 is a spring, and the gap between the sidewall of the first positioning step 210 and the sidewall of the first hole segment 201a is smaller than the wire diameter of the spring. The first positioning step 210 not only serves as a boundary within the locking hole 201, but the radial distance between its sidewall and the sidewall of the first hole segment 201a in the locking hole 201 is designed to be smaller than the wire diameter of the spring, effectively preventing the spring from shifting laterally and sliding into the gap in the unlocked state or during the locking process, thereby reducing the risk of spring jamming. Simultaneously, the first hole segment 201a, as the dedicated placement area for the spring, with its cylindrical boundary and the sidewall of the first positioning step 210 together forming a closed and precise space, ensures that the spring can remain stably centered in any state, unaffected by external factors.
[0031] Specifically, the sidewall of the first positioning step 210 and the sidewall of the first hole segment 201a are radially spaced apart along the locking hole 201; the radial gap between the sidewall of the first positioning step 210 and the sidewall of the first hole segment 201a along the locking hole 201 is L, where 0 < L < 0.3 mm. The first positioning step 210 not only separates the locking hole 201, but also forms a radial limit on the elastic element 300 through the small but crucial gap L between its sidewall and the sidewall of the first hole segment 201a. The gap L is set between 0 and 0.3 mm, ensuring the degree of freedom of the spring in the deformed state, while limiting its excessive expansion, avoiding spring jamming or damage due to friction with the wall surface of the locking hole 201.
[0032] Specifically, the elastic element 300 is a spring; the side wall of the first positioning step 210 is a cylindrical surface, and the outer diameter of the spring is smaller than the diameter corresponding to the cylindrical surface of the first positioning step 210; the outer diameter of the elastic element 300 is smaller than the diameter corresponding to the cylindrical surface of the first positioning step 210. This design ensures that the spring can fit tightly at the first positioning step 210, avoiding excessive radial wobbling of the spring, thereby improving the stability and reliability of the locking structure.
[0033] Specifically, the sidewall of the first hole segment 201a is a cylindrical surface, and the outer diameter of the spring is smaller than the diameter corresponding to the cylindrical surface of the first hole segment 201a. The outer diameter of the spring is also smaller than the diameter corresponding to the cylindrical surface of the first hole segment 201a. This means that the spring can also maintain a good fit within the first hole segment 201a. This not only helps with the positioning of the spring, but also ensures that the spring can freely expand and contract within a limited space when it undergoes elastic deformation, without interfering with or rubbing against the hole wall. This reduces energy loss and improves the durability and consistency of the spring's performance.
[0034] Specifically, the outer diameter of the spring is greater than or equal to the outer diameter of the external thread section 101, and the difference between the outer diameter of the spring and the outer diameter of the external thread section 101 is less than or equal to 0.2 mm. This design provides sufficient contact area between the spring and the locking member 100, ensuring that during locking, the spring can evenly push the locking member 100, allowing it to smoothly engage with the first internal thread section on the foundation to be fixed. Simultaneously, the slight difference between the outer diameter of the spring and the outer diameter of the external thread section 101 avoids direct contact between them within the locking hole 201, preventing wear on the spring during rotation and extending the service life of the spring and the entire locking structure.
[0035] Specifically, the first positioning step 210 has an anti-slip texture structure on the side wall near the second positioning step 120. The anti-slip texture structure consists of multiple annular grooves, which are arranged radially at intervals along the locking hole 201. As a key component inside the locking hole 201, the first positioning step 210 is not limited to simple planar division. By setting annular grooves on its side wall, it provides more precise positioning for the elastic element 300, ensuring that the spring can always be in close contact with the first positioning step 210 when compressed or released, thus avoiding lateral sliding or positional deviation that may occur due to direct contact with the side wall.
[0036] Specifically, such as Figure 2 , Figure 3 As shown, an annular groove 121 is provided on the side wall of the first positioning step 210 near the second positioning step 120. At least a portion of the elastic element 300 is disposed within the annular groove 121 to abut against the first positioning step 210. As a key component inside the locking hole 201, the first positioning step 210's structural design goes beyond simple planar separation. By providing the annular groove 121 on its side wall, at least a portion of the elastic element 300 is placed within the annular groove 121, forming a tight contact with the first positioning step 210. This design not only enhances the radial stability of the spring within the locking hole 201 but also ensures that the spring can quickly and accurately return to its original position when pressure is applied or removed, thus providing continuous and stable elastic support to the locking element 100, ensuring the long-term reliability and smooth operation of the locking structure. The introduction of the annular groove 121 optimizes the contact method between the first positioning step 210 and the elastic element 300, reduces the opportunity for direct contact between the spring and the wall of the locking hole 201, reduces wear caused by friction, and extends the overall service life of the locking structure. At the same time, this design simplifies the installation and positioning process of the elastic element 300, and improves the assembly efficiency and ease of operation of the locking structure.
[0037] Specifically, the elastic element 300 is a spring, which includes a first connecting segment, a second connecting segment, and a third connecting segment connected in sequence. The distance between two adjacent annular rings in the first connecting segment is L1, the distance between two adjacent annular rings in the second connecting segment is L2, and the distance between two adjacent annular rings in the third connecting segment is L3; wherein L1 < L2; L3 < L2. By reducing the distances L1 and L3 between two adjacent annular rings, the first and third connecting segments of the spring achieve a more compact and dense structure compared to L2 in the second connecting segment. This design creates stronger rigid sections at both ends, which can effectively prevent improper radial deformation of the spring and reduce the possibility of jamming in the unlocked state or during the locking process. At the same time, the small distance between L1 and L3 ensures that the end of the spring that abuts against the first positioning step 210 and the locking element 100 can fit tightly, providing stable and continuous elastic force and promoting precise engagement between the locking element 100 and the threaded structure. The second connecting section in the middle maintains the overall elastic characteristics of the spring through a large gap L2, ensuring that the spring can extend and retract freely and smoothly during the rotation of the locking component 100, and will not cause uneven distribution of internal stress due to excessive sealing, thereby affecting the stability of the locking structure and the smoothness of the rotation of the locking component 100.
[0038] This spring structure, composed of the varying spacing between L1, L2, and L3, not only fulfills the basic requirement of a spring as an elastic medium in a locking structure but also significantly enhances its reliability and durability in actual operation through the dense design at both ends. This demonstrates the designer's profound understanding and skillful control over the synergistic effect between the internal structure of the elastic element and the external environment. This spring structure is not only suitable for the screw and stud system of the 400 Remote end (extended end) of server heatsinks but can also be applied to other precision equipment requiring spring-limited positioning. By adjusting the specific values of L1, L2, and L3, it can be adapted to different scenario requirements.
[0039] Specifically, such as Figure 2 As shown, the first positioning step 210 has a second internal thread section 211 on its side wall near the locking member 100, which is adapted to the external thread section 101. The first positioning step 210 not only serves as a support surface for the spring, but the second internal thread section 211 integrated on its side wall also forms a precise threaded engagement with the external thread section 101 of the locking member 100. The presence of the second internal thread section 211 allows the locking member 100 to move accurately along a preset threaded path during its rotation into the locking hole 201 until it is fully engaged with the first internal thread section. During this process, the threaded engagement between the external thread section 101 and the second internal thread section 211 not only guides the precise positioning of the locking member 100, but also increases the fastening force of the locking structure and improves the reliability of the connection through the self-locking effect of the threads.
[0040] Specifically, such as Figures 4 to 6As shown, the locking pin 200 includes a detachable first housing portion 220 and a second housing portion 230. The first housing portion 220 and the second housing portion 230 are symmetrically arranged along a vertical plane to form a locking hole 201. The outer diameter of the externally threaded section is larger than the diameter of the opening at the end of the second hole section 201b near the first hole section 201a. The symmetrical arrangement of the first housing portion 220 and the second housing portion 230 along the vertical plane not only facilitates the manufacturing and disassembly of the locking pin 200, but also ensures the uniformity and symmetry of the two side walls of the locking hole 201, providing a smooth path for the rotation of the locking member 100, and providing a symmetrical constraint environment for the free expansion and contraction of the elastic member 300 within the locking hole 201. This design also facilitates the cleaning and maintenance of the internal space of the locking pin 200, improving the maintainability and service life of the entire locking structure. The outer diameter of the external thread section 101 is designed to be larger than the diameter of the opening of the second hole section 201b at the end furthest from the first hole section 201a. This design allows the housing at the opening end of the second hole section 201b to stop the external thread section 101 after the locking member 100 is installed in the locking hole 201, preventing the external thread section 101 from sliding out of the opening of the second hole section 201b.
[0041] In the above embodiment, a first positioning part 221 is provided on the first housing part 220, and a second positioning part 231 is provided on the second housing part 230 corresponding to the first positioning part 221. In this application, the first positioning part 221 is a protrusion with a bevel and a snap-fit surface, and the second positioning part 231 is a snap-fit groove. When the first housing part 220 and the second housing part 230 are fastened together, the protrusion extends into the snap-fit groove and at least partially extends out of the snap-fit groove. The bevel of the protrusion helps the protrusion slide into the snap-fit groove, and the snap-fit surface of the protrusion snaps with the edge of the snap-fit groove to position the first housing part 220 and the second housing part 230.
[0042] Specifically, the locking pin 200 is detachably mounted on the component to be installed. This detachable mounting feature of the locking pin 200 greatly enhances the adaptability and ease of maintenance of the overall structure. This design allows the locking pin 200 to be easily disassembled and reassembled without damaging the component to be installed, making it possible to replace locking components 100 of different specifications or perform routine maintenance checks. The detachable connection between the component to be installed and the locking pin 200 is achieved through pre-drilled mounting holes or interfaces.
[0043] The detachable connection between the two can be achieved through methods such as threaded connection, snap-fit connection, or other mechanical locking methods. This connection method not only ensures the stability of the locking pin 200 during use, but also allows users to adjust or replace the position of the locking pin 200 according to actual needs, thereby addressing the load-bearing requirements or space limitations in different application scenarios, improving the versatility of the equipment and the user's operating experience.
[0044] Specifically, the wall thickness of the locking pin 200 is greater than or equal to 1 mm. The wall thickness of the locking pin 200 is designed to be greater than or equal to 1 mm; this specification aims to enhance the structural strength and durability of the locking pin 200. The thicker wall ensures that the locking pin 200 maintains its shape and dimensional stability when subjected to external pressure or torque during assembly, effectively preventing deformation or damage caused by excessively thin walls, thereby improving the overall reliability and service life of the locking structure.
[0045] Specifically, the outer diameter of the second positioning step 120 is 4.8-5.0 mm. This size range precisely matches the diameter of the external thread section 101 of the locking member 100 and the inner diameter of the locking hole 201, thus guiding and positioning the locking member 100 as it enters or exits the locking hole 201. This adaptability not only simplifies the assembly process of the locking member 100 but also ensures a tight fit between the locking member 100 and the locking pin 200, reducing locking failures or offset of the locking member 100 due to size mismatch, and improving the stability and tightness of the locking structure.
[0046] Specifically, the outer diameter of the locking post 200 is 7-9 mm. This 7-9 mm outer diameter design not only provides sufficient support to secure the server heatsink 400, but also ensures compatibility between the locking post 200 and other structural components, such as the heatsink 400 body and the base to be fixed. The larger outer diameter provides the locking post 200 with additional strength and rigidity, enabling it to maintain its structural integrity when subjected to pressure applied by the locking member 100 or mechanical impacts encountered during assembly, reducing the risk of bending or breakage of the locking post 200 due to an excessively small outer diameter.
[0047] like Figure 7 As shown, a server includes the aforementioned locking structure. The server also includes a heat sink 400 and a server body. A locking pin 200 of the locking structure is mounted on a mounting plate 410 of the heat sink 400. A stud is mounted on the server body, and the stud has a second internal thread. A locking member 100 of the locking structure passes through a locking hole 201 and is locked to the stud to mount the heat sink 400 onto the server body. The locking pin 200, as part of the locking structure, is mounted on the mounting plate 410 of the heat sink 400, and its built-in locking hole 201 is designed to receive the locking member 100. The locking pin 200 not only bears the weight of the locking member 100 and the elastic member 300, but also, through its specific structural design, such as the step diameter and hole size, ensures the correct guidance and support of the locking member 100 and the elastic member 300 during the locking process, providing a stable operating platform for the entire locking process.
[0048] In this application, the mounting plate 410 is the base for the locking structure to be installed. The mounting plate 410 is fitted to the heat dissipation structure of the server, and the heat of the heat dissipation structure of the server is conducted.
[0049] The studs installed on the server body have a second internal thread segment that forms a complementary threaded connection with the external thread segment 101 of the locking member 100. When the locking member 100 passes through the locking hole 201, and its external thread segment 101 engages with the second internal thread segment on the stud, the locking member 100 can smoothly screw into the stud until the preset locking depth is reached. This process ensures a robust connection between the heat sink 400 and the server body, providing sufficient clamping force to cope with the thermal stress and external vibration generated during server operation, thus guaranteeing the installation stability and heat dissipation efficiency of the heat sink 400.
[0050] Stable and reliable locking effect: Through the synergistic effect of the locking element 100 and the elastic element 300 provided in the locking pin 200, the locking structure can smoothly transition between the deformed state and the initial state, thus providing a stable and reliable connection method for the component to be installed and the foundation to be fixed.
[0051] Precise dimensional control: The wall thickness of the locking pin 200, the outer diameter of the second positioning step 120, and the outer diameter of the locking pin 200 are all carefully designed to optimize structural strength and dimensional matching, ensure the precise guidance and positioning of the locking element 100, and the effective limiting of the elastic element 300, thereby improving the accuracy of the locking operation and the durability of the locking structure.
[0052] Enhanced elastic element limiting capability: The design of the first positioning step 210 directly abutting against the elastic element 300 restricts the radial movement of the elastic element 300, ensuring its stability within the locking hole 201. At the same time, by controlling the gap between the side wall of the first positioning step 210 and the side wall of the first hole segment 201a, the jamming phenomenon of the elastic element 300 during the locking process is effectively avoided, improving the smoothness of the locking operation.
[0053] Improved friction and positioning: The anti-slip textured structure or annular groove 121 on the side wall of the first positioning step 210 enhances the frictional contact with the elastic element 300, such as a spring, preventing the elastic element from slipping under stress. At the same time, it optimizes the positioning of the elastic element, ensuring its correct placement in the locking hole 201, further improving the stability of the locking structure and the rotation efficiency of the locking element 100.
[0054] Optimized design of the locking component: The locking component 100 includes an external thread section 101 and a second positioning step 120. This design allows the locking component 100 to engage with the first internal thread section of the foundation to be fixed, and to achieve precise positioning within the locking hole 201. This ensures the guidance and stability of the locking component 100 during the tightening process. At the same time, it abuts against the other end of the elastic component 300, forming a closed loop for the transmission of locking force.
[0055] Ease of disassembly of locking pin 200: The detachable design of locking pin 200, including the combination of first housing part 220 and second housing part 230, and the detachable connection with the part to be installed, makes maintenance and upgrades simple and quick. Locking pins can be easily replaced or adjusted without major changes to the overall structure, improving the maintainability and adaptability of the equipment.
[0056] The locking structure of this application is not only suitable for the installation of server heat sink 400, but can also be widely used in various applications that require screw or bolt locking, such as the assembly of heat dissipation modules for communication base stations. By adjusting the size of the components, it can meet the locking requirements of different scenarios, demonstrating the flexibility and practicality of its design.
[0057] In summary, the technical solution of this application effectively improves the accuracy, stability, and ease of maintenance of the locking operation by optimizing the size and shape of multiple components of the locking structure, providing an efficient and reliable locking solution for various devices requiring threaded connections.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
