[0001] This application relates to the field of radiator screw fastening technology, and more specifically, to a fastening tool. Background Technology

[0002] In the server manufacturing industry, CPU (Central Processing Unit) heat dissipation is of paramount importance.

[0003] In existing technologies, the heat sink fastening method involves tightening the screws located at the four corners of the heat sink one by one. This process is not only time-consuming, but also prone to uneven force during fastening, which can affect the contact between the heat sink and the CPU, thereby affecting the heat dissipation efficiency and the stability of the server.

[0010] Furthermore, the ratio of the number of teeth Z3 of the third gear to the number of teeth Z4 of the fourth gear satisfies: 1.5≤Z3 / Z4≤2; and / or, the ratio of the number of teeth Z2 of the second gear to the number of teeth Z3 of the third gear satisfies: 0.5≤Z2 / Z3≤1.5; and / or, the ratio of the number of teeth Z2 of the second gear to the number of teeth Z4 of the fourth gear satisfies: 1.5≤Z2 / Z4≤2.

[0011] Furthermore, the locking tool also includes: a first mating part disposed on the first end of the drive shaft; an operating structure having a gripping part and a second mating part connected to each other, one of the first mating part and the second mating part being a protrusion, and the other of the first mating part and the second mating part being a recess, the protrusion extending into the recess and engaging with the recess in a limiting fit, so as to drive the drive shaft to rotate through the operating structure.

[0012] Furthermore, the locking tool also includes: a base plate having a first through hole, through which the end of the driven shaft passes and connects to the locking part; or, at least a portion of the locking part passes through the first through hole and connects to the end of the driven shaft; a top plate being disposed opposite to the base plate and connected to the base plate, the top plate having a second through hole being disposed opposite to the drive shaft, at least a portion of the second mating part extending into the second through hole and engaging with the first mating part in a limiting fit; wherein the base plate and / or the top plate are made of a transparent material.

[0013] Furthermore, the locking tool also includes: a surrounding plate, which is connected to both the bottom plate and the top plate to form a receiving cavity, the surrounding plate being made of a transparent material; and / or, a sealing structure, detachably disposed at the second through hole to seal or avoid the second through hole.

[0015] The present invention provides a locking tool for securing a heatsink to a motherboard. The tool includes an operating component, multiple locking components, and a transmission component. The operating component includes a drive shaft and a first rotating part sleeved on the drive shaft. Multiple locking components are circumferentially spaced around the drive shaft. Each locking component includes a driven shaft, a second rotating part, and a locking part.

The first rotating part is connected to multiple second rotating parts via the transmission component, driving the multiple second rotating parts and the locking part to rotate synchronously. Thus, the operator only needs to operate the drive shaft to rotate, transmitting power from the drive shaft to the multiple locking components via the transmission component, achieving synchronous locking of the multiple locking components. This ensures uniform force distribution at multiple locking points during heatsink installation and removal, avoiding motherboard damage caused by uneven force distribution due to single-point locking.

Meanwhile, the locking tool adopts a multi-point locking position linkage design, eliminating the tedious steps of traditional individual locking. Workers only need to operate once to complete the locking of the entire radiator, which greatly shortens the assembly time, improves the work efficiency of the production line, and reduces labor costs.

[0031] 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.

[0032] To address the problem of uneven force affecting heat dissipation performance when fastening heat sinks in existing technologies, this application provides a fastening tool.

[0033] like Figures 1 to 3As shown, the fastening tool is used to fasten the heatsink to the motherboard. The fastening tool includes an operating component 10, multiple fastening components 20, and a transmission component 30. The operating component 10 includes a drive shaft 11 and a first rotating part 12 sleeved on the drive shaft 11. The multiple fastening components 20 are circumferentially spaced around the drive shaft 11. Each fastening component 20 includes a driven shaft 21, a second rotating part 22, and a locking part 23. The second rotating part 22 is sleeved on the driven shaft 21, and the locking part 23 is disposed on the first end of the driven shaft 21 to rotate synchronously with the driven shaft 21. The first rotating part 12 is connected to the multiple second rotating parts 22 via the transmission component 30 to drive the multiple second rotating parts 22 and the locking part 23 to rotate synchronously.

[0034] By applying the technical solution of this embodiment, the operator only needs to rotate the drive shaft 11, and the power of the drive shaft 11 is transmitted to multiple locking components 20 through the transmission component 30 to achieve synchronous locking of multiple locking components 20. This ensures that the multiple locking positions of the heat sink are evenly stressed during installation and disassembly, avoiding damage to the motherboard caused by uneven stress due to single-point locking. This solves the problem of uneven stress affecting heat dissipation performance in the prior art for heat sink locking, ensuring the heat dissipation performance of the heat sink. At the same time, the locking tool adopts a multi-point linkage design, eliminating the cumbersome steps of traditional one-by-one locking. The operator only needs to complete the locking of the entire heat sink in one operation, which greatly shortens the assembly time, improves the work efficiency of the production line, and reduces labor costs.

[0035] In this embodiment, the locking part 23 is a screwdriver.

[0036] In this embodiment, there are four locking components 20, which are arranged circumferentially around the drive shaft 11 to achieve four-end linkage locking of the heat sink, thereby meeting the assembly requirements of the heat sink and the motherboard and improving the connection stability between the two.

[0037] It should be noted that the number of locking components 20 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be two, three, five, six, or more locking components 20.

[0038] Optionally, there are multiple transmission components 30, which are circumferentially spaced around the drive shaft 11. Each transmission component 30 corresponds one-to-one with a locking component 20. The first rotating part 12 drives the second rotating part 22 of the corresponding locking component 20 to rotate through each transmission component 30. In this way, the second rotating part 22 of each locking component 20 is connected to the first rotating part 12 of the drive shaft 11 through its corresponding transmission component 30, ensuring that when the first rotating part 12 rotates, the second rotating parts 22 of all locking components 20 rotate simultaneously and precisely. This synchronization avoids uneven force during radiator locking, improving the stability and safety of the locking process. Furthermore, the one-to-one correspondence between the transmission components 30 and the locking components 20 means that when maintaining or replacing a part, the problem can be precisely located, facilitating targeted adjustments or replacements, reducing maintenance time, and improving equipment maintenance efficiency.

[0039] In this embodiment, there are four transmission components 30, each corresponding to one of the four locking components 20. Through precise matching and linkage between the four transmission components 30 and the four locking components 20, synchronous, precise, efficient, and simplified operation of the heat sink locking is achieved, which helps improve the production efficiency and quality of server assembly, while also reducing production costs and equipment maintenance complexity. Furthermore, the design of four transmission components 30 allows employees to operate the drive shaft 11 only once to simultaneously drive all locking components 20, significantly shortening the locking time.

[0040] It should be noted that the number of transmission components 30 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the transmission components 30 may be two, three, five, six, or more.

[0041] In this embodiment, the first rotating part 12 is a first gear, and the second rotating part 22 is a second gear. This meshing between the gears ensures precise force transmission. The rotation of the first gear accurately drives the second gear through the transmission assembly 30, achieving synchronous rotation between the drive shaft 11 and the driven shaft 21 in the locking tool. This prevents damage to the mainboard due to uneven force during the locking process. Furthermore, this design simplifies the structure of the first rotating part 12 and the second rotating part 22, making them easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the locking tool.

[0042] In other embodiments not shown in the accompanying drawings, the first rotating part is a first sprocket, and the second rotating part is a second sprocket. In this way, the sprocket drive system can withstand a larger load and has better stability at high speeds compared to gear drives. The contact between the sprocket teeth and the chain pins ensures more stable force transmission during locking, reducing uneven locking caused by wear or slippage of parts.

[0043] like Figure 2 and Figure 3 As shown, each transmission component 30 includes a transmission shaft 31, a third gear 32, and a fourth gear 33. The third gear 32 is mounted on the transmission shaft 31 and meshes with the first gear, while the fourth gear 33 is mounted on the transmission shaft 31 and meshes with the second gear. The third gear 32 and the fourth gear 33 are spaced apart along the central axis of the transmission shaft 31, and their central axes are coaxial. This ensures that the rotational force of the drive shaft 11 is accurately transmitted to the transmission component 30 through the meshing of the third gear 32 with the first gear, and that the meshing of the fourth gear 33 with the second gear accurately transmits this rotational force to the driven shaft 21 of the locking component 20. Because the third gear 32 and the fourth gear 33 are coaxial, their rotation occurs on the same central line, ensuring the synchronicity of all locking components 20 during heat sink locking, thus preventing motherboard damage due to uneven force distribution.

[0044] In this embodiment, the force is evenly distributed during the locking process through the precise meshing between the gears, improving the stability of the locking tool when locking the radiator. Simultaneously, the mechanical properties of the gears ensure smooth and precise rotation, reducing vibration and displacement during the locking process, which helps improve locking quality and efficiency.

[0045] Optionally, the number of teeth on the third gear 32 is greater than the number of teeth on the fourth gear 33; and / or, the third gear 32 and the fourth gear 33 are integrally formed. In this way, the aforementioned relationship between the number of teeth on the third gear 32 and the fourth gear 33 constitutes a reduction ratio, meaning that the force transmitted from the first gear to the third gear 32 is amplified when transmitted to the fourth gear 33, while the rotational speed is correspondingly reduced. This design achieves amplification of the locking force and conversion of speed, ensuring that the locking process is both powerful and smooth, improving locking efficiency and safety. Simultaneously, the integrally formed gear structure has higher structural strength and precision, avoiding a decrease in precision due to wear after prolonged use, thereby improving the durability of the locking tool and reducing maintenance and replacement costs.

[0046] In this embodiment, the third gear 32 has a greater number of teeth than the fourth gear 33, and the third gear 32 and the fourth gear 33 are integrally formed. This combination of gears with different numbers of teeth optimizes torque distribution, ensuring that each screw receives sufficient force evenly when securing the four corners of the radiator, thereby improving the stability and consistency of the securing process.

[0047] Optionally, the ratio of the number of teeth Z3 of the third gear 32 to the number of teeth Z4 of the fourth gear 33 satisfies: 1.5 ≤ Z3 / Z4 ≤ 2; and / or, the ratio of the number of teeth Z2 of the second gear to the number of teeth Z3 of the third gear 32 satisfies: 0.5 ≤ Z2 / Z3 ≤ 1.5; and / or, the ratio of the number of teeth Z2 of the second gear to the number of teeth Z4 of the fourth gear 33 satisfies: 1.5 ≤ Z2 / Z4 ≤ 2. Thus, during the fastening process of the fastening tool, the above-mentioned setting of the ratio of the number of teeth Z3 of the third gear 32 to the number of teeth Z4 of the fourth gear 33 ensures that the force on the drive shaft 11 is amplified and transmitted to the driven shaft 21 of the fastening assembly 20, ensuring sufficient torque when fastening the screw, while reducing the physical exertion of the operator during the fastening process. The aforementioned settings of the ratio of the number of teeth Z2 of the second gear to the number of teeth Z3 of the third gear 32, and the ratio of the number of teeth Z2 of the second gear to the number of teeth Z4 of the fourth gear 33, enable the locking tool to ensure both force and speed, thereby improving production efficiency.

[0048] In this embodiment, the number of teeth Z2 of the second gear is the same as the number of teeth Z3 of the third gear 32. By carefully designing the gear tooth ratio, not only can the torque distribution and speed control of the fastening tool during the fastening process be optimized, but the fastening accuracy can also be improved, energy consumption reduced, and wear reduced. At the same time, the adaptability of the fastening tool is enhanced, and the operation process is simplified. This has an important impact on improving the overall production quality and efficiency, and helps to improve the practicality and durability of the fastening tool on the server assembly line.

[0049] like Figure 2 and Figure 3 As shown, the locking tool also includes a first mating part 40 and an operating structure. The first mating part 40 is disposed on the first end of the drive shaft 11. The operating structure has a gripping part and a second mating part connected to each other. One of the first mating part 40 and the second mating part is a protrusion, and the other is a recess. The protrusion extends into the recess and engages with it, thereby driving the drive shaft 11 to rotate via the operating structure. This design of the gripping part and the mating part allows the operator to control the rotation of the locking tool more stably and accurately, ensuring a uniform force distribution during the four-point locking process of the radiator. Simultaneously, the limiting engagement design of the protrusion and the recess provides the operator with intuitive feedback during rotation, enhancing controllability and preventing operational errors.

[0050] Specifically, the operating structure drives the drive shaft 11 to rotate, simplifying the operation steps during the locking process. This eliminates the need for the operator to operate each of the four locking points separately; a simple rotation of the operating structure simultaneously locks or disengages all four points, significantly improving locking efficiency and reducing working hours.

[0051] In this embodiment, the operating mechanism is a screwdriver.

[0052] like Figures 1 to 3 As shown, the locking tool also includes a base plate 50 and a top plate 60. The base plate 50 has a first through hole through which the end of the driven shaft 21 passes and connects to the locking part 23; alternatively, at least a portion of the locking part 23 passes through the first through hole and connects to the end of the driven shaft 21. The top plate 60 is positioned opposite to the base plate 50 and connected to it. The top plate 60 has a second through hole 61 opposite to the drive shaft 11. At least a portion of the second mating part extends into the second through hole 61 and engages with the first mating part 40 for limiting engagement. Thus, the base plate 50 and the top plate 60 provide the basic framework of the locking tool. The relative fixation between them and the positioning of the drive shaft 11 and the driven shaft 21 through the through hole ensure structural stability and precise alignment of the locking part 23 during the locking process, thereby ensuring the durability and locking accuracy of the locking tool under high-intensity use.

[0053] Specifically, the connection between the first through hole on the base plate 50 and the driven shaft 21, or the connection between the locking part 23 and the driven shaft 21 through the first through hole, not only enhances the integration between the locking part 23 and the transmission assembly, but also improves the flexibility of the locking part 23, making it easier to adapt to screws and radiators of different sizes, thus enhancing the versatility and applicability of the fastening tool. The second through hole 61 on the top plate 60 is positioned opposite to the drive shaft 11, allowing the second mating part of the operating structure to easily extend into the second through hole 61 and engage with the first mating part 40 for limiting engagement. This simplifies the operator's operation process when using the fastening tool, allowing the fastening or disassembly process to be completed without additional tools, improving operational efficiency and reducing production downtime. Simultaneously, the positioning of the drive shaft 11 and the driven shaft 21 by the top plate 60 and the base plate 50 optimizes the force transmission path, ensuring that the force applied by the operator can be directly and effectively transmitted to the locking part 23, reducing force loss and unnecessary friction, and improving the torque transmission efficiency of the fastening process.

[0054] Optionally, the base plate 50 and / or top plate 60 are made of a transparent material. In this way, the transparent base plate 50 and / or top plate 60 allow the operator to directly observe the connection between the driven shaft 21 and the locking part 23, as well as the movement state of the drive shaft 11, during the locking process. This improves the operator's control over the locking process, helps to promptly detect and resolve misalignment issues during the locking process, and improves the accuracy and efficiency of the locking.

[0055] In this embodiment, both the bottom plate 50 and the top plate 60 are made of transparent material.

[0056] Optionally, the locking tool also includes a surrounding plate 70, which is connected to both the bottom plate 50 and the top plate 60 to form a receiving cavity. The surrounding plate 70 is made of a transparent material. And / or, the locking tool also includes a sealing structure, which is detachably disposed at the second through hole 61 to block or avoid the second through hole 61. In this way, the surrounding plate 70, the bottom plate 50, and the top plate 60 form a closed receiving cavity, effectively protecting the internal components from external factors such as dust and moisture, extending the service life of the locking tool, and isolating the operator from the internal moving parts, thus improving operational safety. Simultaneously, the detachable sealing structure at the second through hole 61 allows for sealing of the second through hole 61 when the locking tool is not in use, preventing dust and other impurities from entering the locking tool through the second through hole 61 and contaminating the gears.

[0057] In this embodiment, the enclosure 70 is made of transparent material, which allows the operator to clearly observe the operating status of the internal components, helping to identify and solve problems in a timely manner, and improve production efficiency and product quality.

[0058] like Figure 3 As shown, the base plate 50 has a first mounting portion and a second mounting portion, and the locking tool also includes a first bearing structure 80 and a second bearing structure 90. The first bearing structure 80 is disposed within the first mounting portion, and the second end of the drive shaft 11 extends into and connects to the first bearing structure 80. The second bearing structure 90 is disposed within the second mounting portion, and the first end of the transmission shaft 31 extends into and connects to the second bearing structure 90. This arrangement of the bearing structures (first bearing structure 80 and second bearing structure 90) significantly reduces the friction and wear of the drive shaft 11 and transmission shaft 31 during rotation, greatly reduces the direct contact between the shafts and the base plate, and improves the durability and service life of the locking tool.

[0059] In this embodiment, the arrangement of the first and second mounting parts, along with the matching installation of the first bearing structure 80 and the second bearing structure 90, simplifies the assembly process of the fastening tool, making maintenance and bearing replacement easier, reducing maintenance costs and downtime, and improving the continuity and reliability of the production line. Thus, by setting the first bearing structure 80 and the second bearing structure 90 on the base plate 50, and precisely connecting the drive shaft 11 and the transmission shaft 31 to the bearing structures, not only is the rotational accuracy and stability of the fastening tool significantly improved, but friction and wear are also reduced, spatial layout is optimized, operational comfort is enhanced, efficient torque transmission is achieved, and the reliability and stability of fastening are improved.

[0060] like Figure 3 As shown, the top plate 60 has a third mounting portion and a fourth mounting portion, and the fastening tool also includes a third bearing structure 100 and a fourth bearing structure 110. The third bearing structure 100 is disposed within the third mounting portion, and the second end of the driven shaft 21 extends into and connects to the third bearing structure 100. The fourth bearing structure 110 is disposed within the fourth mounting portion, and the second end of the drive shaft 31 extends into and connects to the fourth bearing structure 110. This arrangement of the third bearing structure 100 and the fourth bearing structure 110 ensures smooth rotation and precise positioning of the driven shaft 21 and the drive shaft 31. The bearing structures increase rotational stability by reducing friction between the shaft and the support, contributing to the uniform distribution of force during the four-point fastening process of the radiator, and improving fastening accuracy and quality. Simultaneously, the design of the third and fourth mounting portions, and the matching installation of the third bearing structure 100 and the fourth bearing structure 110, makes bearing maintenance and replacement more convenient, reducing maintenance costs and downtime, and improving production continuity.

[0061] In this embodiment, the third bearing structure 100 and the fourth bearing structure 110 can effectively reduce the wear of the driven shaft 21 and the transmission shaft 31 during operation, extending the overall service life of the locking tool. By reducing the direct contact between the shaft and the top plate 60, damage to the shaft and the top plate caused by friction and vibration is avoided.

[0062] Optionally, the locking tool also includes a protective sleeve covering at least a portion of the locking part 23 to protect it; and / or, the locking tool also includes a handle 120 disposed on the top plate 60. In this way, the protective sleeve effectively isolates the locking part 23 from direct contact with the external environment, preventing external factors such as dust, impurities, and moisture from damaging or affecting its performance. This extends the service life of the locking part 23 and reduces maintenance costs and the failure rate of the locking tool, especially in complex production environments. The handle 120, disposed on the top plate 60, is often ergonomically designed in its position and shape to ensure that the operator can naturally grip the handle for operation, reducing pressure on the hand and wrist and improving operating efficiency and comfort.

[0063] In this embodiment, the locking tool further includes a protective sleeve and a handle. The protective sleeve covers at least a portion of the locking portion 23 to protect it. The handle 120 is provided on the top plate 60.

[0064] Optionally, there are two handles 120, which are spaced apart along the length of the top plate 60.

[0065] like Figure 3As shown, the top plate 60 has a fifth mounting portion, and the locking tool also includes a fifth bearing structure 130. The fifth bearing structure 130 is disposed in the fifth mounting portion, and the first end of the drive shaft 11 extends into the fifth bearing structure 130 and is connected to the fifth bearing structure 130.

[0066] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0067] A locking tool is used to lock a heatsink onto a motherboard. The tool includes an operating component, multiple locking components, and a transmission component. The operating component includes a drive shaft and a first rotating part sleeved on the drive shaft. Multiple locking components are circumferentially spaced around the drive shaft. Each locking component includes a driven shaft, a second rotating part, and a locking part. The second rotating part is sleeved on the driven shaft, and the locking part is located at the first end of the driven shaft to rotate synchronously with it. The first rotating part is connected to the multiple second rotating parts via the transmission component, driving the multiple second rotating parts and the locking part to rotate synchronously. In this way, the operator only needs to operate the drive shaft to rotate, and the transmission component transmits the power of the drive shaft to the multiple locking components, achieving synchronous locking of the multiple locking components. This ensures that the multiple locking points of the heatsink are evenly stressed during installation and removal, avoiding motherboard damage caused by uneven stress due to single-point locking. This solves the problem of uneven stress affecting heat dissipation performance in existing heatsink locking technologies, ensuring the heatsink's heat dissipation performance. Meanwhile, the locking tool adopts a multi-point locking position linkage design, eliminating the tedious steps of traditional individual locking. Workers only need to operate once to complete the locking of the entire radiator, which greatly shortens the assembly time, improves the work efficiency of the production line, and reduces labor costs.

[0068] The foregoing has provided a detailed description of a chassis panel and server provided in this application.
