[0002] Screws are widely used as connecting components in the assembly of many types of products due to their low cost, ease of use, and high reliability. To improve the stability of the connection, components are usually assembled and secured with multiple screws. For example, a CPU cooler is typically secured to the CPU with a screw at each of its four corners.

[0003] When there are many screws, both installation and disassembly currently require screwing each screw individually with a screwdriver, which undoubtedly leads to low assembly and disassembly efficiency. Utility Model Content

Each driven wheel is connected to the drive wheel via a transmission, and each driven wheel is connected to a screwdriver, so that the drive wheel can drive multiple screwdrivers to rotate synchronously through the multiple driven wheels, thereby simultaneously disassembling and assembling multiple screws.

[0006] In one alternative embodiment, the mounting base includes a base and a top cover, the base and the top cover being fastened together and enclosing a transmission cavity, in which a driving wheel and multiple driven wheels are rotatably disposed.

[0007] In one alternative embodiment, a drive shaft and multiple driven shafts are rotatably disposed in the transmission cavity. The drive wheel is sleeved and fixed on the drive shaft, and the multiple driven wheels are sleeved and fixed on the driven shafts one by one. The top end of the drive shaft protrudes from the top cover and is connected to the drive component, while the bottom end of the driven shaft passes through the base and is used to connect to a screwdriver.

[0008] In one alternative embodiment, the drive shaft includes a first sleeve, the bottom end of which is rotatably engaged with the base, and the first sleeve passes through the drive wheel and the top cover sequentially from bottom to top, with the top end of the first sleeve being inserted and fixed to the drive component.

[0010] In one alternative embodiment, a first protruding ring is provided on the first sleeve, and the first protruding ring is placed between the drive wheel and the base.

[0011] In one alternative embodiment, the driven shaft includes a second sleeve, the top end of which is rotatably engaged with the top cover, the second sleeve passing through the driven wheel from top to bottom and into the base, and the bottom end of the second sleeve being detachably inserted and fixed to a second connecting post on a screwdriver.

[0012] In one alternative embodiment, the inner wall of the top cover is provided with a limiting protrusion, and the top end of the second sleeve is rotatably fitted onto the limiting protrusion.

[0040] In order to improve the disassembly and assembly efficiency when there are a large number of screws, this application considers setting a corresponding transmission mechanism between the drive component and multiple screwdrivers to obtain a disassembly and assembly tool that can simultaneously tighten multiple screws.

[0041] It should be noted that the specific embodiments provided below and in the accompanying drawings are mainly for the disassembly and assembly of CPU heatsinks, and do not constitute a limitation on the application scenarios of the disassembly and assembly tools.

[0042] Please see Figure 1 and Figure 2 The figures show the three-dimensional structure and exploded structure of the disassembly and assembly tool provided in the embodiments of this application. As shown in the figures, the disassembly and assembly tool 100 includes: a mounting base 110, a driving component 120, a driving wheel 130, and a plurality of driven wheels 140. The driving wheel 130 and the plurality of driven wheels 140 are rotatably mounted on the mounting base 110, and the plurality of driven wheels 140 are distributed circumferentially along the driving wheel 130. Each driven wheel 140 is drive-connected to the driving wheel 130. Specifically, the driving wheel 130 and the driven wheels 140 can be... Figure 2 The gears shown are driven by meshing teeth. Of course, the driving gear 130 and the driven gear 140 can also be pulleys, and each driven gear 140 is connected to the driving gear 130 by a synchronous belt.

[0043] The drive component 120 is connected to the drive wheel 130 and is used to drive the drive wheel 130 to rotate. Specifically, the drive component 120 can be a manually operated rotary handle as shown in the figure, or an automatically driven motor, etc.

[0044] Each driven wheel 140 is connected to a screwdriver 200, so that the driving wheel 130 can drive multiple screwdrivers 200 to rotate synchronously through multiple driven wheels 140, thereby simultaneously removing and installing multiple screws. It should be noted that the driven wheels 140 and screwdrivers 200 can be detachable, meaning that the driven wheels 140 can have a pre-installed standard connector, and the screwdrivers 200 can be commercially available quick-change screwdrivers, thus allowing for switching between different sizes of screwdrivers 200 on the disassembly and assembly tool 100. Of course, in some other embodiments, the screwdrivers 200 and driven wheels 140 can also be an integral or non-detachable structure.

[0045] Furthermore, the specific number and distribution of the driven wheels 140 can be designed according to the distribution of screws on the parts to be disassembled and assembled. Figure 1 and Figure 2In the specific embodiment shown, in order to be able to assemble and disassemble the screws at the four corners of the CPU heatsink, the number of driven wheels 140 is set to four, and the distribution of the screwdrivers 200 connected to the driven wheels 140 is consistent with the distribution of the screws at the four corners of the CPU heatsink.

[0046] Please see Figure 3 The figure shows the state of disassembling and assembling the CPU heatsink 300 using the disassembly and assembly tool 100, taking the CPU heatsink 300 as an example. As shown in the figure, first, align each screwdriver 200 with each screw 310 on the CPU heatsink 300. Then, from a top-down perspective, the drive wheel 130 is driven to rotate clockwise by the drive component 120. The drive wheel 130 drives each driven wheel 140 that meshes with it to rotate counterclockwise. Correspondingly, each screwdriver 200 will rotate counterclockwise with the driven wheel 140 connected to it, thereby disassembling multiple screws 310 simultaneously. The screws 310 used in the CPU heatsink 300 are generally anti-loosening screws. Therefore, when there is no resistance or little resistance during disassembly, it indicates that the screw 310 has been unscrewed from the screw hole. It should be noted that if the driving pulley 130 and the driven pulley 140 are pulleys and driven by a synchronous belt, then during disassembly, the driving pulley 130 will be rotated counterclockwise by the driving component 120, so that the driving pulley 130 drives each driven pulley 140 to rotate counterclockwise. During installation, simply reverse the above steps. When you feel a lot of resistance when turning, it indicates that each screw 310 has been tightened.

[0047] During installation, as the screws 310 are screwed in deeper, the disassembly tool 100 and screwdriver 200 will move downwards. Therefore, in order to ensure that each screw 310 can be effectively tightened and to prevent over-tightening and stripping, the distance between the bottom of the mounting base 110 and the bottom of the screwdriver 200 can be set to be equal to the distance between the top of the CPU heatsink 300 and the top of the screw 310 after it is fully screwed in. Thus, during installation, when the screw 310 is fully screwed in, the bottom of the mounting base 110 will contact the top of the CPU heatsink 300, thereby acting as a limit and preventing damage from further tightening.

[0048] Furthermore, such as Figure 2 As shown, when using a conventional screwdriver 200 for disassembly and assembly, in order to meet the aforementioned distance setting requirements, a groove 111 can be provided at the bottom of the mounting base 110. After the screw 310 is fully screwed in, the bottom of the groove 111 contacts and limits the contact with the top surface of the CPU heatsink 300.

[0049] To ensure consistent adjustment distances for each screw during assembly and disassembly, and thus to guarantee even force distribution on the CPU heatsink 300 at each screw 310, the transmission ratio between each driven wheel 140 and the driving wheel 130 is preferably set to be equal. This means the driving wheel 130 will drive each driven wheel 140 to rotate at the same speed. In actual production, due to machining errors, the screw depths of each screw 310 on the CPU heatsink 300 may be inconsistent. By setting the rotation speed of each driven wheel 140 to the same value, it is possible to detect which screws 310 are screwed in too deeply or too shallowly, and then make targeted adjustments to ensure even force distribution on the CPU heatsink 300 at the CPU, thus guaranteeing its heat dissipation capabilities.

[0050] Specifically, the screws 310 on the CPU heatsink 300 typically have a pitch of about 1mm and are tightened approximately 4 turns. However, due to errors in actual manufacturing, the actual pitch and tightening number cannot be accurately guaranteed. Therefore, when using the disassembly tool 100 provided in this embodiment to simultaneously tighten multiple screws 310 on the CPU heatsink 300, after the screwdriver 200 rotates the corresponding number of turns, it ensures that all screws 310 have rotated the same number of turns. Then, remove the disassembly tool 100 and check if any screws 310 are too tight or too loose. If two diagonally opposite screws 310 are too tight or too loose, only the two diagonally opposite screwdrivers 200 on the disassembly tool 100 can be retained, and the two diagonally opposite screws 310 can be adjusted. If a single screw 310 is too tight or too loose, it can be considered whether it needs to be replaced based on the actual situation.

[0051] In addition, the speed ratio between each driven wheel 140 and the driving wheel 130 can be set to less than 1 to ensure that when the driving member 120 drives the driving wheel 130 to rotate, the driven wheel 140 can drive the screwdriver 200 to rotate at a lower speed and a higher torque, thereby ensuring that the screwdriver 200 can reliably tighten the screw 310 and preventing the screwdriver 200 from slipping.

[0052] exist Figure 2 In the specific embodiment shown, the driving wheel 130 and each driven wheel 140 have the same module, wherein the driving wheel 130 has 39 teeth and the driven wheel 140 has 20 teeth. The transmission ratio between the driven wheel 140 and the driving wheel 130 is about 0.5, ensuring that when the driving wheel 130 rotates two revolutions, the driven wheel 140 rotates about one revolution.

[0053] In summary, the disassembly and assembly tool 100 provided in this application embodiment, in order to enable the simultaneous tightening and adjustment of multiple screws, adopts a method of arranging multiple driven wheels 140 on the outer periphery of the driving wheel 130, and individually connecting each driven wheel 140 to the driving wheel 130 for transmission, so that when the driving member 120 drives the driving wheel 130 to rotate, all driven wheels 140 will rotate in the same direction. On this basis, by connecting a screwdriver 200 to each driven wheel 140, multiple screwdrivers 200 can rotate synchronously and in the same direction, thereby realizing the disassembly and assembly operation of multiple screws synchronously, which is beneficial to improving the disassembly and assembly efficiency of parts.

[0054] To protect the working environment of the driving wheel 130 and the driven wheel 140, and to prevent dust and other impurities from adhering to their surfaces and affecting the transmission effect between them, such as... Figure 2 As shown, the mounting base 110 may include a base 112 and a top cover 113. The base 112 and the top cover 113 are fastened together and enclosed to form a transmission cavity 114. The driving wheel 130 and a plurality of driven wheels 140 are rotatably disposed in the transmission cavity 114. The base 112 and the top cover 113 may be fixed to each other by means of snap-fit, threaded fasteners, etc.

[0055] The base 112 and the top cover 113 are interlocked, and the driving wheel 130 and the driven wheel 140 are placed in the transmission cavity 114 formed by the interlocking of the base 112 and the top cover 113, so that the base 112 and the top cover 113 can provide a cover protection for the driving wheel 130 and the driven wheel 140, thereby ensuring the reliability of the transmission of the driving wheel 130 and the driven wheel 140.

[0056] Regarding the connection between the driving wheel 130 and the driving member 120, and between the driven wheel 140 and the screwdriver 200, this application proposes an implementation method, which can be found in the following description. Figure 2 and further combine Figure 4 and Figure 5 ,in Figure 4 The side structure of the disassembly / assembly tool 100 is shown. Figure 5 It shows Figure 4 The cross-sectional structure along AA is shown in the figure. A drive shaft 131 and multiple driven shafts 141 are rotatably disposed in the transmission cavity 114. A drive wheel 130 is sleeved and fixed to the drive shaft 131, and multiple driven wheels 140 are correspondingly sleeved and fixed to the driven shafts 141. The top end of the drive shaft 131 protrudes from the top cover 113 and is connected to the drive component 120. The bottom end of the driven shaft 141 passes through the base 112 and is used to connect to the screwdriver 200.

[0057] Specifically, the active shaft 131 and the driven shaft 141 can be rotatably connected to the mounting base 110 through shaft hole fitting, bearings, etc. The active shaft 131 and the driving component 120 can be fixed to each other by welding, snap-fit, threaded connection or key connection, and the driven shaft 141 and the screwdriver 200 can also be fixed to each other by welding, snap-fit, threaded connection or key connection.

[0058] Please combine Figure 5 and Figure 6 Furthermore, the drive shaft 131 may include a first sleeve 1311, the bottom end of which is rotatably engaged with the base 112. Specifically, a convex shaft 1312 may be provided at the bottom end of the first sleeve 1311, and a corresponding first connecting hole 1121 may be provided on the base 112. The convex shaft 1312 is rotatably inserted into the first connecting hole 1121, so that a rotatable engagement is formed between the first sleeve 1311 and the base 112. The first sleeve 1311 passes through the drive wheel 130 and the top cover 113 sequentially from bottom to top, and the top end of the first sleeve 1311 is inserted and fixedly connected to the drive member 120.

[0059] When the drive unit 120 uses a manually operated handle, such as Figure 6 As shown, the drive component 120 may include a screwing part 121 and a first connecting post 122 disposed at the bottom end of the screwing part 121. The first connecting post 122 is inserted and fixed in the first sleeve 1311.

[0060] When operating the drive component 120 to drive the drive wheel 130 to rotate, in order to reduce the driving resistance, such as Figure 5 and Figure 6 As shown, a first protruding ring 1313 can be provided on the first sleeve 1311. The first protruding ring 1313 can be an integral structure with the first sleeve 1311, or it can be fixed to the first sleeve 1311 by a sleeve connection. After assembly, the first protruding ring 1313 is placed between the drive wheel 130 and the base 112, so that a certain gap is formed between the drive wheel 130 and the base 112. Based on this, the drive wheel 130 no longer contacts the base 112, so when the drive wheel 130 rotates, the drive wheel 130 does not rub against the base 112, but the friction is caused by the first protruding ring 1313 and the base 112. Since the contact area between the first protruding ring 1313 and the base 112 is small, it can be ensured that the frictional resistance experienced by the drive wheel 130 and the drive shaft 131 when rotating is small, ensuring that the operation of the drive component 120 is easy and effortless. In addition, the first protruding ring 1313 can also limit the first sleeve 1311. Since the upper and lower parts of the first protruding ring 1313 abut against the drive wheel 130 and the base 112 respectively, the first sleeve 1311, which is fixed relative to the first protruding ring 1313, cannot move freely up and down, thereby ensuring that the first sleeve 1311 will not move axially during operation and ensuring its stability during rotation.

[0061] Please combine Figure 2 and Figure 5 The driven shaft 141 may include a second sleeve 1411. The top end of the second sleeve 1411 is rotatably engaged with the top cover 113. Specifically, the inner wall of the top cover 113 may be provided with a limiting protrusion 1131, and the top end of the second sleeve 1411 is rotatably sleeved on the limiting protrusion 1131. The second sleeve 1411 passes through the driven wheel 140 from top to bottom and enters the base 112. The bottom end of the second sleeve 1411 is used for detachable insertion and fixation with the second connecting post 210 on the screwdriver 200.

[0062] Similarly, in order to reduce the resistance when the driven wheel 140 rotates, such as Figure 2 and Figure 5 As shown, a second protruding ring 1412 is provided on the second sleeve 1411. The second protruding ring 1412 overlaps the top of the driven wheel 140. The second protruding ring 1412 has a basically the same function as the first protruding ring 1313, mainly to separate the top of the driven wheel 140 from the inner wall of the top cover 113, so as to prevent them from directly contacting each other and generating large frictional force, which would affect the flexibility of the driven wheel 140's rotation. In addition, since the upward movement of the second protruding ring 1412 is restricted by the top cover 113, and the downward movement is restricted by the driven wheel 140, the vertical movement of the second sleeve 1411, which is fixed relative to the second protruding ring 1412, is restricted, thereby ensuring that the second sleeve 1411 will not undergo large axial movement and ensuring the smoothness of rotation.

[0063] Furthermore, in order to reduce the frictional resistance between the second sleeve 1411 and the base 112 when the second sleeve 1411 rotates, such as Figure 5 and Figure 6 As shown, the base 112 has a through hole 1122 for the second sleeve 1411 to pass through. The inner wall of the base 112 located at the edge of the through hole 1122 is provided with a support protrusion ring 1123. The support protrusion ring 1123 supports the bottom of the driven wheel 140 to lift the driven wheel 140, so that the driven wheel 140 and the inner wall of the base 112 are spaced apart. When the driven wheel 140 rotates, its bottom is in frictional contact with the support protrusion ring 1123. Since the contact area between the two is small, the frictional resistance generated is also small, thereby ensuring the flexibility of the driven wheel 140 rotation.

[0064] For ease of assembly, in the specific embodiment shown in the attached drawings, both the first sleeve 1311 and the second sleeve 1411 are square-section sleeves. Square through holes are correspondingly formed on the driving wheel 130 and the driven wheel 140. After the first sleeve 1311 and the second sleeve 1411 pass through the driving wheel 130 and the driven wheel 140 respectively, they can be relatively fixed to each other. Furthermore, the dimensions of the second sleeve 1411 are designed to allow it to be inserted and fixed with conventional quick-release screwdrivers on the market, thereby saving the cost of custom-made screwdrivers 200 and allowing for easy replacement of screwdrivers 200 of different specifications.

[0065] For the first sleeve 1311 and the second sleeve 1411 with square cross-section, the diameter of the hole on the top cover 113 through which the first sleeve 1311 passes should be set to be slightly larger than the diameter of the circumference formed after the first sleeve 1311 rotates, so as to ensure the flexibility of the first sleeve 1311 rotation. The same applies to the through hole 1122 on the base 112 through which the second sleeve 1411 passes.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
