Description

Technical Field

[0001] This application relates to the field of radiator installation technology, and more particularly to a radiator screw parallel locking device. Background Technology

[0002] Heat sinks are essential components of servers, and their stability directly affects the server's stability, energy consumption, and lifespan. Heat sinks are typically installed using screws. During installation, an electric screwdriver is needed to sequentially tighten several screws around the heat sink using a cyclical tightening method. However, this method is relatively cumbersome and can lead to the heat sink tilting, affecting heat dissipation.

[0003] To address the aforementioned issues, related technologies employ an electric screwdriver to drive a drive rod, and a gear set to simultaneously rotate several screwdriver bits, enabling the simultaneous tightening of multiple screws and improving installation efficiency to some extent.

[0004] However, due to the different design dimensions of radiators applied in different scenarios, the number and position of screws for each model of radiator are different, making it difficult to adapt to radiators with different screw spacing using existing fastening devices. Utility Model Content

[0005] This application provides a parallel locking device for radiator screws. Through the coordinated action of the adjustment mechanism and the transmission mechanism, the locking mechanism can be adjusted according to the screw position of different radiators, thus solving the problem of limited applicability of traditional locking devices.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] This application provides a parallel locking device for radiator screws, the device comprising:

[0008] Drive shaft;

[0009] At least two locking mechanisms are provided, each locking mechanism being connected to the drive shaft based on a transmission mechanism, and having a bit at one end that engages with a radiator screw; the locking mechanism is configured such that it is driven by the transmission mechanism when the drive shaft rotates, so that the bit rotates synchronously with the drive shaft.

[0010] An adjustment mechanism, connected to a locking mechanism, is configured to adjust the relative distance between the locking mechanisms so that the position of the bit corresponds to that of the radiator screw.

[0011] Based on this solution, multiple locking mechanisms are rotated synchronously via a drive shaft, and the spacing between each locking mechanism is adjusted using an adjustment mechanism. This solves the problem of cumbersome operation caused by tightening screws one by one in related technologies, and also overcomes the defect of radiator tilting caused by uneven screw tightening. The synchronous rotation of multiple screwdriver heads ensures uniform distribution of locking force, preventing radiator deformation due to uneven force. In addition, the adjustment mechanism allows the device to adapt to designs with different screw spacings, improving the device's versatility.

[0012] In one possible implementation, a support mechanism is also included; the support mechanism includes a bottom plate and a top plate arranged opposite each other; the bottom plate is connected to the top plate by at least one telescopic rod to change the distance between the bottom plate and the top plate by means of the telescopic rod;

[0013] The drive shaft is rotatably connected to the top plate; the top plate is provided with a first through hole, which is used to allow the locking mechanism to pass through the top plate;

[0014] The base plate has a second through hole, which is used to allow the bit to pass through the base plate.

[0015] Based on this solution, the support mechanism consisting of a top plate, a bottom plate, and telescopic rods provides dynamic support for other mechanisms, improving the overall structural strength. At the same time, the top plate can move close to the bottom plate along the telescopic rods, and the telescopic rods provide stable guidance for the movement of the device, ensuring the stability and reliability of the locking process.

[0016] In one possible implementation, the regulating mechanism includes:

[0017] A first adjusting component is used to adjust the relative distance between locking mechanisms arranged along a first direction;

[0018] The second adjustment component is used to adjust the relative distance between the locking mechanisms arranged along a second direction; the second direction is perpendicular to the first direction.

[0019] Based on this solution, the first adjusting component adjusts the spacing of the locking mechanism along a first direction, and the second adjusting component adjusts the spacing along a perpendicular second direction, thus solving the technical problem of adaptive screw position in a two-dimensional plane. The bidirectional orthogonal adjustment allows the screwdriver bit to cover any arranged screw holes, avoiding the shortcomings of traditional single-direction adjustment which cannot cover oblique or asymmetrical layouts, and ensuring the positioning accuracy of simultaneous locking of multiple screws.

[0020] In one possible implementation, the first regulating component includes:

[0021] A movable plate is provided on one side of the top plate; the movable plate is provided with a third through hole, which is used to allow the locking mechanism to pass through the movable plate;

[0022] First operating unit; the first operating unit is connected to the movable plate and is used to adjust the position of the movable plate relative to the top plate along the first direction;

[0023] The second adjustment component includes:

[0024] A bearing connector is provided in the third through hole, and the bearing connector is rotatably connected to the locking mechanism through a bearing;

[0025] Second operating part; the second operating part is connected to the bearing connector and is used to adjust the position of the bearing connector in the third through hole along the second direction.

[0026] Based on this solution, the movement of the movable plate is controlled by the first operating unit to achieve overall adjustment of several locking mechanisms along the first direction, and the movement of the bearing connector is controlled by the second operating unit to achieve adjustment of a single locking mechanism along the second direction, ensuring that each locking mechanism is quickly adjusted to the target position.

[0027] In one possible implementation, the first operation unit includes:

[0028] Fixed block; the fixed block is connected to the top plate;

[0029] A first threaded rod extending in a first direction; a first operating element is provided at one end of the first threaded rod; the other end of the first threaded rod passes through the fixed block and is rotatably connected to the moving plate; the first threaded rod is threadedly connected to the fixed block.

[0030] Based on this solution, the threaded transmission between the first threaded rod and the fixed block enables precise displacement control of the moving plate. The thread pitch design of the threaded rod converts rotational motion into linear motion. Combined with the knob operation of the first operating component, this allows the operator to intuitively adjust the position of the moving plate, avoiding the coarseness and cumulative errors of manual sliding adjustment.

[0031] In one possible implementation, the second operation unit includes:

[0032] A second threaded rod extending in a second direction; a second operating element is provided at one end of the second threaded rod; the other end of the second threaded rod passes through the movable plate and is rotatably connected to the bearing connector; the second threaded rod is threadedly connected to the movable plate.

[0033] Based on this scheme, the threaded drive bearing connecting the second threaded rod and the moving plate moves precisely in the second direction. The axial force transmission characteristics of the threaded rod ensure a stable and wobbly adjustment process. At the same time, the operation of the second operating component is relatively independent from that of the first operating component, so that the lateral and longitudinal adjustments of the locking mechanism do not interfere with each other, thus improving the coordination efficiency of multi-directional adjustments.

[0034] In one possible implementation, an auxiliary plate is provided on one side of the base plate; the base plate is provided with at least one first connecting hole for detachable connection between the base plate and the auxiliary plate; the auxiliary plate is provided with a fourth through hole for passing the bit through the auxiliary plate.

[0035] Based on this solution, the auxiliary plate of the base plate works in conjunction with the adjustment mechanism to avoid the problem of a single axial positioning reference for the bit, providing a limit for the bit and ensuring the positional accuracy of the bit.

[0036] In one possible implementation, the supporting mechanisms also include:

[0037] Guide tube; one end of the guide tube is detachably connected to the auxiliary plate; the other end of the guide tube passes through the fourth through hole and extends in a direction away from the auxiliary plate; the guide tube is formed with a guide hole for the bit to pass through.

[0038] Based on this solution, the guide cylinder constrains the radial displacement of the bit, ensuring that it feeds only along the axial direction. Combined with the limiting structure of the fourth through hole, it can prevent the screw from stripping due to bit swing during the fastening process, significantly reducing lateral force interference during screw fastening and improving the thread engagement quality.

[0039] In one possible implementation, a cover plate is provided above the top plate, and a first side plate, a second side plate, a third side plate, and a fourth side plate are located between the cover plate and the top plate; the top plate, the first side plate, the second side plate, the third side plate, the fourth side plate, and the cover plate together form a closed space for accommodating the transmission mechanism.

[0040] Based on this solution, the enclosed space formed by the top plate, side plates, and cover plate solves the problems of easy contamination and noise leakage in the transmission mechanism. The enclosed structure prevents external dust from entering the transmission system, prevents the transmission belt from slipping or the pulley from wearing, and at the same time reduces the noise radiation of high-speed rotating parts, thus improving the operating environment of the equipment.

[0041] In one possible implementation, the locking mechanism includes a first pulley; a second pulley is provided on the drive shaft; and the transmission mechanism includes a transmission belt connecting the first pulley and the second pulley.

[0042] Based on this solution, stepless torque distribution is achieved by using belt drive, ensuring that the rotation speed of all bits is strictly synchronized, avoiding the speed difference problem caused by manufacturing errors in traditional gear drive, and ensuring the consistency of multi-screw fastening.

[0043] In one possible implementation, a third pulley is provided on the top plate, and a drive belt connects the first pulley, the second pulley, and the third pulley so that when the second pulley rotates, the first pulley and the third pulley rotate synchronously.

[0044] Based on this solution, a third pulley is added that works in conjunction with the first and second pulleys, resolving the issue of uneven torque distribution on one side of the transmission. The third pulley can dynamically compensate for changes in transmission belt tension, preventing slippage and extending the lifespan of the transmission system.

[0045] In one possible implementation, the top plate has a first groove; a first slider is provided in the first groove and is slidably connected to the first groove; a third pulley is rotatably connected to the first slider.

[0046] Based on this scheme, the first slider slides in the first groove of the top plate. The tension of the transmission belt can be controlled by adjusting the position of the first slider, so as to ensure stable power transmission efficiency.

[0047] In one possible implementation, a stepped portion is provided in the first groove; a sliding portion is provided in the first slider; the sliding portion cooperates with the stepped portion to adjust the position of the first slider in the first groove.

[0048] Based on this solution, the first slider slides within the first groove, which is easier to process and implement compared to other sliding structures.

[0049] In one possible implementation, the locking mechanism further includes an overload protection device disposed between the first pulley and the bit.

[0050] Based on this solution, an overload protection device is installed between the first pulley and the bit to prevent damage to the radiator screws or bit due to overload torque, thereby improving the safety and reliability of the device.

[0051] In one possible implementation, the locking mechanism further includes a floating shaft located on the outer periphery of the bit near the first pulley.

[0052] Based on this solution, the floating shaft allows the bit to adaptively adjust the axis direction within a certain angle, compensating for the manufacturing tolerances and installation errors of the heat sink, reducing the alignment requirements between the bit and the screw hole, and improving the device's compatibility with irregularly shaped heat sinks.

[0053] In one possible implementation, the top surface of the cover plate is provided with a handle assembly.

[0054] Based on this solution, the handle assembly is located on the top surface of the cover plate, solving the problem of inconvenient device movement and positioning. The ergonomic handle conforms to the mechanical design of grip, allowing operators to operate the handle with one hand to complete device positioning, while using the other hand for auxiliary adjustments, significantly improving work efficiency and reducing fatigue during long-term operation.

[0055] In one possible implementation, the transmission belt is a double-sided toothed transmission belt; the first pulley, the second pulley, and the third pulley are each provided with a toothed structure that mates with the transmission belt.

[0056] Based on this solution, a double-sided toothed drive belt and pulley tooth profile meshing is adopted to prevent drive belt slippage and power loss. The double-sided tooth structure improves transmission efficiency by increasing the number of meshing points. The tooth profile matching design ensures continuous and stable power transmission, especially during high-speed locking, it can still maintain low vibration and low noise, and shorten the average locking time of a single screw.

Detailed Implementation

[0079] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. To facilitate a clear description of the technical solutions of the embodiments of this application, the use of terms such as "first," "second," etc., in the embodiments of this application is for illustrative purposes and to distinguish the objects being described. There is no particular order between them, nor does it indicate a specific limitation on the number of devices in the embodiments of this application, and they do not constitute any limitation on the embodiments of this application.

[0080] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0081] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0082] In the description of this application, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer" (if any) indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In this application, unless otherwise expressly specified and limited, "upper" or "lower" of the first feature and the second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0083] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities connected are not linked by an intermediate structure, but are simply connected to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0084] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0085] Radiators typically use screws as the primary means of fixing them. The number and location of screws vary depending on the size, model, and type of the radiator. For example, a radiator may have four, six, or other screws. The screws are usually located around the perimeter of the radiator, such as having a screw hole and screw at each of the four corners. When the side length of the radiator is long, one or more screw holes and screws can be added at the evenly divided points of the side length to increase the stability of the screw fixing.

[0086] In order to enable the locking device to be applicable to the installation of radiators with various screw positions, this application provides a radiator screw parallel locking device with adjustable locking mechanism position.

[0087] See Figure 1 This is a top view of the top plate in a parallel screw fastening device for radiators provided in some embodiments of this application; see also Figure 2 This is a bottom view of the top plate in a parallel screw fastening device for radiators provided in some embodiments of this application.

[0088] See some examples. Figure 1 The parallel locking device for radiator screws provided in this application includes:

[0089] Drive shaft 100; Drive shaft 100 is the active shaft that drives the parallel locking device to perform the locking action. Drive shaft 100 is used to connect to the output end of the electric screwdriver so that the electric screwdriver outputs power to the parallel locking device, causing drive shaft 100 to rotate.

[0090] In some examples, the drive shaft 100 can be driven by an electric screwdriver to rotate clockwise or counterclockwise to achieve locking or unlocking functions.

[0091] See Figure 1The parallel locking device for radiator screws provided in this application also includes at least two locking mechanisms 200. The number of locking mechanisms 200 is equal to the number of screws installed on the radiator, for example, it can be two, four, six or other numbers. When there are two screws, they can be located on both sides of the radiator; when there are four screws, they can be located at the four corners of the radiator; when there are more than four screws, they can be arranged in a matrix according to rows and columns. The locking mechanism 200 is connected to the drive shaft 100 based on the transmission mechanism 300, and one end is provided with a screwdriver bit 210 that cooperates with the radiator screw. In the embodiment of this application, the locking mechanism 200 is configured to be driven by the transmission mechanism 300 when the drive shaft 100 rotates, so that the screwdriver bit 210 rotates synchronously with the drive shaft 100. In this way, when each screwdriver bit 210 corresponds to one screw of the radiator, the synchronous rotation of the screwdriver bit 210 makes all screws tighten synchronously, which increases the installation efficiency while ensuring the installation effect of the radiator.

[0092] It should be noted that, in this embodiment, the synchronous rotation of the bit 210 with the drive shaft 100 refers to the synchronization of the bit 210 and the drive shaft 100 in time; that is, when the drive shaft 100 starts rotating, the bit 210 also starts rotating; when the drive shaft 100 stops rotating, the bit 210 also stops rotating. Synchronous rotation of the bit 210 with the drive shaft 100 can also mean that the rotation direction is the same; that is, when the drive shaft 100 rotates clockwise, the bit 210 also rotates clockwise, and vice versa. However, synchronous rotation of the bit 210 with the drive shaft 100 should not be understood merely as the bit 210 and the drive shaft 100 rotating at the same angle. For example, when the drive shaft 100 rotates one revolution, the bit 210 may rotate one revolution, or it may rotate half a revolution or more revolutions due to different transmission ratios. In this case, it is only necessary to ensure that the rotation angles of each bit 210 are consistent, thereby ensuring consistent tightening effect on each screw.

[0093] See Figure 2 The parallel locking device for radiator screws provided in this application also includes an adjustment mechanism 400, which is connected to the locking mechanism 200. The adjustment mechanism 400 is configured to adjust the relative distance between the locking mechanisms 200 so that the position of the screwdriver bit 210 corresponds to the radiator screw.

[0094] In some examples, an independent adjustment mechanism 400 can be set for each locking mechanism 200 to ensure that the position of each bit 210 can be adjusted individually.

[0095] In some examples, multiple adjustment mechanisms 400 used to adjust different locking mechanisms 200 can be integrated along a certain direction, which can improve adjustment efficiency and ensure that the adjusted locking mechanism 200 can maintain alignment accuracy in that direction.

[0096] In this embodiment, the adjustment mechanism 400 allows for adjustment of the relative distance between the locking mechanisms 200, based on the different screw positions designed for the radiator, while maintaining a fixed number of locking mechanisms 200. This ensures that the screwdriver bit 210 is precisely aligned with each screw. Furthermore, the electric screwdriver drives the drive shaft 100 to rotate, causing all the screwdriver bits 210 to rotate synchronously and precisely tighten each screw.

[0097] In some examples, when it is necessary to disassemble the heat sink, the relative distance between the locking mechanisms 200 can be adjusted according to the adjustment mechanism 400 so that the screwdriver bit 210 is aligned with the screw. Then, the drive shaft 100 is rotated in the opposite direction by the electric screwdriver to loosen all the screws at the same time, thereby improving the disassembly efficiency.

[0098] Based on this solution, multiple locking mechanisms 200 are synchronously rotated via the drive shaft 100, and the spacing between each locking mechanism 200 is adjusted by the adjustment mechanism 400. This solves the problem of cumbersome operation caused by tightening screws one by one in related technologies, and also overcomes the defect of radiator tilting caused by uneven screw tightening. The synchronous rotation of multiple screwdriver bits 210 ensures uniform distribution of locking force, preventing deformation of the radiator due to uneven force. In addition, the adjustment mechanism 400 allows the device to adapt to designs with different screw spacings, improving the device's versatility.

[0099] See Figure 3 This is a schematic diagram of the support mechanism in the parallel locking device for radiator screws provided in some embodiments of this application;

[0100] During the tightening operation of the radiator screws by the screwdriver bit 210, the locking mechanism 200, the transmission mechanism 300, and the drive shaft 100 as a whole need to move downwards in the tightening direction. To ensure the overall stability of the device during this downward movement, see [reference needed]. Figure 3 In some examples, the parallel locking device for radiator screws provided in this application also includes a support mechanism 500. The support mechanism 500 provides support for other components and provides stable guidance for the downward movement of the locking mechanism 200, the transmission mechanism 300, and the drive shaft 100. Specifically, the support mechanism 500 includes a base plate 510 and a top plate 520 disposed opposite to each other. The base plate 510 is located directly below the top plate 520, and the two are arranged parallel to each other. The base plate 510 is connected to the top plate 520 by at least one telescopic rod 530, so as to change the distance between the base plate 510 and the top plate 520 by means of the telescopic rod 530.

[0101] The drive shaft 100 is rotatably connected to the top plate 520; the top plate 520 is provided with a first through hole 521 for the locking mechanism 200 to pass through the top plate 520; the bottom plate 510 is provided with a second through hole 511 for the bit 210 to pass through the bottom plate 510. In this embodiment, the top plate 520 provides stable support for the adjustment mechanism 400, the locking mechanism 200 connected to the adjustment mechanism 400, and the transmission mechanism 300 connected between the drive shaft 100 and the locking mechanism 200, while the bottom plate 510 provides overall dynamic support for the top plate 520 and the components it supports through the telescopic rod 530.

[0102] In some examples, the number of first through holes 521 can be multiple;

[0103] In some examples, the number of locking mechanisms 200 that can pass through the first through hole 521 can be one or more. For example, locking mechanisms 200 arranged in the same row or column can be inserted into the same first through hole 521 to achieve centralized control of multiple locking mechanisms 200.

[0104] In some examples, the number of second through holes 511 can also be set according to the number of bits 210, that is, each second through hole 511 is used to pass through one bit 210.

[0105] In this embodiment, the support mechanism 500, consisting of a top plate 520, a bottom plate 510, and a telescopic rod 530, provides dynamic support for other mechanisms and improves the overall structural strength. Meanwhile, the top plate 520 can move closer to the bottom plate 510 along the telescopic rod 530, and the telescopic rod 530 provides stable guidance for the movement of the device, ensuring the stability and reliability of the locking process.

[0106] In some examples, considering that some radiators have a relatively high local height, when the locking device of this application is used to install the radiator, the base plate 510 may easily interfere with the radiator. In order to avoid interference, the second through hole 511 can be set as one, so that the high part of the radiator can pass through the base plate 510 without affecting the passage of all the bit 210, thereby increasing the applicability of the device of this application.

[0107] In some examples, when the adjusting mechanism 400 adjusts the position of the locking mechanism 200, the adjustment process can typically be divided into lateral adjustment and longitudinal adjustment based on the array arrangement of the locking mechanisms 200. Therefore, see [link to relevant documentation]. Figure 2 The regulating mechanism 400 may further include:

[0108] The first adjustment component 410 is used to adjust the relative distance between the locking mechanisms 200 arranged along the first direction;

[0109] The second adjustment component 420 is used to adjust the relative distance between the locking mechanisms 200 arranged along a second direction; the second direction is perpendicular to the first direction.

[0110] See Figure 4 This is a schematic diagram illustrating the process of adjusting the locking device by the adjusting mechanism provided in some embodiments of this application;

[0111] See some examples. Figure 4 When the adjustment mechanism 400 is divided into two directions of adjustment, different adjustment methods can be used for the matrix-arranged locking mechanism 200. Taking a locking mechanism 200 with four locking mechanisms as an example... Figure 4 In the diagram, ① represents the position of the locking mechanism 200 before adjustment, and ② represents the target adjustment position of the locking mechanism 200. When there is a misalignment between the target adjustment position and the position before adjustment of the locking mechanism 200 in both the horizontal and vertical directions, the locking mechanism 200 can be adjusted as a whole in the horizontal direction first to align it with the target adjustment position in the vertical direction. Figure 4 Middle (a) to Figure 4 Next, adjust the locking components 200 along the longitudinal direction to align the locking mechanism 200 with the target adjustment position in the lateral direction, such as... Figure 4 (b) to Figure 4 In the middle (d), all locking mechanisms 200 are precisely adjusted from their initial positions to the target adjustment positions. Similarly, the locking mechanisms 200 can be adjusted as a whole along the longitudinal direction to align with the target adjustment position in the lateral direction, such as... Figure 4 Middle (a) to Figure 4 In the middle (c), adjust the locking mechanism 200 in the lateral direction to align it with the target adjustment position in the longitudinal direction, such as... Figure 4 (c) to Figure 4 In the middle (d), it is also possible to precisely adjust all locking mechanisms 200 from the initial position to the target adjustment position.

[0112] In this embodiment, the first adjusting component 410 adjusts the spacing of the locking mechanism 200 along a first direction, and the second adjusting component 420 adjusts the spacing of the locking mechanism 200 along a perpendicular second direction, thus solving the technical problem of adaptive screw position in a two-dimensional plane. The bidirectional orthogonal adjustment allows the screwdriver bit 210 to cover any arranged screw holes, making it particularly suitable for scenarios where radiator screws are irregularly arranged, ensuring the positioning accuracy of simultaneous locking of multiple screws.

[0113] It should be noted that, in the embodiments of this application, the first adjustment component 410 and the second adjustment component 420 are not limited to being used for adjustment in a specific direction. Instead, depending on whether the adjustment object is the whole or a single locking mechanism 200, the adjustment component that realizes the overall adjustment of the locking mechanism 200 can be defined as the first adjustment component 410, and the adjustment component that realizes the adjustment of a single locking mechanism 200 can be defined as the second adjustment component 420.

[0114] See Figure 5 This is a schematic diagram of the adjusting mechanism in a parallel locking device for radiator screws provided in some embodiments of this application; see also Figure 6 This is a schematic diagram showing the relationship between the first adjustment component and the second adjustment component provided in some embodiments of this application;

[0115] In some examples, to achieve overall position adjustment of multiple locking mechanisms 200, see [reference needed]. Figure 5 The first adjustment component 410 may include:

[0116] A movable plate 411 is disposed on one side of the top plate 520. The movable plate 411 has a third through hole 4111, which is used to allow the locking mechanism 200 to pass through the movable plate 411. Since the movable plate 411 also serves to support the locking mechanism 200, in some examples, the movable plate 411 can be slidably connected to the top plate 520, or it can be connected to some support members that are slidably connected to the top plate 520, so as to achieve a more stable support effect for the locking mechanism 200.

[0117] In some examples, the number of third through holes 4111 can be set according to the number of locking mechanisms 200 that need to be adjusted as a whole. At the same time, the third through holes 4111 provide adjustment space for subsequent adjustment of individual locking mechanisms 200. Therefore, when designing the third through holes 4111, it is necessary to ensure that they have a certain length along the second direction (the direction in which the second adjustment component 420 performs the adjustment).

[0118] The first adjustment assembly 410 also includes a first operation part 412; the first operation part 412 is connected to the movable plate 411 and is used to adjust the position of the movable plate 411 relative to the top plate 520 along the first direction; through the adjustment of the first operation part 412, the movable plate 411 can slide along the first direction, thereby driving the several locking mechanisms 200 to move as a whole, ensuring that they are adjusted to the target adjustment position in the horizontal or vertical direction.

[0119] See some examples. Figure 5 The first operating unit 412 may further include:

[0120] Fixing block 4121; fixing block 4121 is connected to top plate 520; to facilitate adjustment by multiple adjustment mechanisms 400, fixing block 4121 can be set on the bottom or side of top plate 520.

[0121] The first operating part 412 also includes a first threaded rod 4122 extending along a first direction; one end of the first threaded rod 4122 is provided with a first operating element 4123; the other end of the first threaded rod 4122 passes through the fixing block 4121 and is rotatably connected to the moving plate 411; the first threaded rod 4122 is threadedly connected to the fixing block 4121.

[0122] In this embodiment of the application, when it is necessary to adjust the overall position of the locking mechanism 200, the first operating member 4123 can be rotated to drive the first threaded rod 4122 to rotate. Due to the thread limit of the first threaded rod 4122 and the moving plate 411, the moving plate 411 moves along the first direction under the action of the first threaded rod 4122. At this time, the first direction can be the direction close to the fixed block 4121 or the direction away from the fixed block 4121.

[0123] In this embodiment, the threaded transmission between the first threaded rod 4122 and the fixed block 4121 enables precise displacement control of the moving plate 411. The pitch design of the first threaded rod 4122 converts rotational motion into linear motion. Combined with the knob operation of the first operating component 4123, this allows the operator to intuitively adjust the position of the moving plate 411, avoiding the coarseness and cumulative errors of manual sliding adjustment.

[0124] See some examples. Figure 6 To achieve position adjustment of a single locking mechanism 200, a set of second adjustment components 420 can be provided based on each third through hole 4111. The second adjustment component 420 may specifically include:

[0125] A bearing connector 421 is provided in the third through hole 4111. The bearing connector 421 is rotatably connected to the locking mechanism 200 through the bearing 220. The bearing connector 421 is connected to the outer ring of the bearing 220, and the inner ring of the bearing 220 rotates synchronously with the locking mechanism 200.

[0126] The second adjustment assembly 420 also includes a second operation part 422; the second operation part 422 is connected to the bearing connector 421 and is used to adjust the position of the bearing connector 421 in the third through hole 4111 along the second direction; through the adjustment of the second operation part 422, the bearing connector 421 can move within the third through hole 4111, thereby achieving precise positioning of the locking mechanism 200 in the second direction.

[0127] In some examples, the outer diameter of the bearing 220 can be larger than the inner diameter of the third through hole 4111, so that the moving plate 411 slides in contact with the bearing 220 while providing a certain support and limiting effect on the bearing 220 (locking mechanism 200), ensuring its stability and reliability during movement.

[0128] See some examples. Figure 6 The second operation unit 422 may further include:

[0129] A second threaded rod 4221 extends along a second direction; one end of the second threaded rod 4221 is provided with a second operating member 4222; the other end of the second threaded rod 4221 passes through the moving plate 411 and is rotatably connected to the bearing connector 421; the second threaded rod 4221 is threadedly connected to the moving plate 411.

[0130] In this embodiment of the application, when it is necessary to adjust the position of the locking mechanism 200, the second operating member 4222 can be rotated to drive the second threaded rod 4221 to rotate. Due to the thread limit of the second threaded rod 4221 and the bearing connector 421, the bearing connector 421 moves along the second direction under the action of the second threaded rod 4221. At this time, the second direction can be the direction closer to the second operating member 4222 or the direction farther away from the second operating member 4222.

[0131] In this embodiment, the threaded rod 4221 and the threaded drive bearing connector 421 of the moving plate 411 move precisely in the second direction. The axial force transmission characteristics of the second threaded rod 4221 ensure stable and wobbly adjustment. Simultaneously, the operation of the second operating member 4222 is relatively independent of the first operating member 4123, ensuring that the lateral and longitudinal adjustments of the locking mechanism 200 do not interfere with each other, thus improving the collaborative efficiency of multi-directional adjustments.

[0132] See Figure 7 This is a diagram showing the connection relationship between the base plate and the auxiliary plate in the parallel locking device for radiator screws provided in some embodiments of this application.

[0133] See some examples. Figure 7 An auxiliary plate 540 is provided on one side of the base plate 510. The auxiliary plate 540 can be located on the side of the base plate 510 closer to the top plate 520 or on the side of the base plate 510 farther from the top plate 520. The auxiliary plate 540 is used to cooperate with the adjustment mechanism 400 to adjust the position of the locking mechanism 200 and to provide support and limit for the locking mechanism 200. It should be noted that although the position adjustment of the locking mechanism 200 mainly depends on the operator's operation of the adjustment mechanism 400, and the auxiliary plate 540 does not directly participate in the position adjustment of the locking mechanism 200, the auxiliary plate 540 should provide sufficient space and stability for the locking mechanism 200 when the position is adjusted, so as to avoid interfering with the adjustment of the locking mechanism 200.

[0134] To achieve this effect, see some examples. Figure 7The base plate 510 may be provided with at least one first connecting hole 512, which is used for detachable connection between the base plate 510 and the auxiliary plate 540. When the locking mechanism 200 is adjusted along the first direction, the auxiliary plate 540 can adjust its position accordingly as the locking mechanism 200 moves, and be aligned and connected with a corresponding first connecting hole 512.

[0135] Based on this solution, the auxiliary plate 540 of the base plate 510 cooperates with the adjustment mechanism 400 to avoid the problem of a single axial positioning reference for the bit 210, and provides a limit for the bit 210 to ensure the positional accuracy of the bit 210.

[0136] In some examples, the auxiliary plate 540 and the first connecting hole 512 can be connected by bolts, pins or other fasteners, which is not limited in the embodiments of this application.

[0137] In some examples, the auxiliary plate 540 has a fourth through hole 541, which allows the bit 210 to pass through the auxiliary plate 540. It should be noted that the length of the fourth through hole 541 along the second direction should meet the movement requirements of the bit 210 during the adjustment process, ensuring that the movement of the bit 210 in the second direction is not interfered with by the auxiliary plate 540.

[0138] See Figure 8 This is a schematic diagram of the assembly of the base plate in the parallel screw fastening device for radiators provided in some embodiments of this application; see also Figure 9 The diagram below shows the structure of the guide tube provided in some embodiments of this application.

[0139] See some examples. Figure 8 and Figure 9 The supporting organization 500 also includes:

[0140] Guide cylinder 550; one end of guide cylinder 550 is detachably connected to auxiliary plate 540; the other end of guide cylinder 550 passes through fourth through hole 541 and extends in a direction away from auxiliary plate 540; guide cylinder 550 is formed with guide hole 551 for the bit 210 to pass through.

[0141] In this embodiment, the guide cylinder 550 guides the movement of the bit 210, and the guide hole 551 forms the operating space for the bit 210 to tighten the radiator screw. Therefore, the position of the guide cylinder 550 needs to correspond to the position of the radiator screw. The guide cylinder 550 and the auxiliary plate 540 are detachable, and the position of the guide cylinder 550 along the second direction can be flexibly adjusted. When the guide cylinder 550 and the auxiliary plate 540 are fixed, its position can be adjusted along the first direction with the auxiliary plate 540, thereby realizing the position adjustment of the guide cylinder 550.

[0142] Based on this solution, the guide cylinder 550 constrains the radial displacement of the bit 210, ensuring that it feeds only along the axial direction. Combined with the limiting structure of the fourth through hole 541, it can prevent the screw stripping defect caused by the swing of the bit 210 during the fastening process, significantly reduce the lateral force interference during screw fastening, and improve the thread engagement quality.

[0143] In some examples, when the position of the locking mechanism 200 needs to be adjusted, the guide cylinder 550 can be removed from the auxiliary plate 540 and the auxiliary plate 540 can be removed from the base plate 510. Then, the adjustment mechanism 400 is operated according to the target position of the locking mechanism 200. After the locking mechanism 200 reaches the target position, the auxiliary plate 540 is reconnected to the base plate 510, and then the guide cylinder 550 is connected to the auxiliary plate 540 to ensure that the guide hole 551 of the guide cylinder 550 is aligned with the position of the radiator screw, thereby ensuring the precise alignment of the bit 210 and the radiator screw.

[0144] See Figure 10 This is a schematic diagram of the installation of the parallel locking device for radiator screws and the radiator provided in some embodiments of this application;

[0145] In some examples, the extension length of the guide cylinder 550 may be greater than or equal to the height of the radiator, so that the locking device of this application, when performing a locking operation on the radiator, can refer to... Figure 10 The bottom end of the guide cylinder 550 can reach the bottom of the radiator. At this time, the guide cylinder 550 not only provides guidance and limiting function for the bit 210, but also supports the locking device.

[0146] See Figure 11 This is a schematic diagram of the top structure of the support mechanism provided in some embodiments of this application; see also Figure 12 ,for Figure 11 Another perspective structural diagram of the support mechanism provided in the diagram.

[0147] See some examples. Figure 11 and Figure 12 A cover plate 560 is provided above the top plate 520, and a first side plate 5201, a second side plate 5202, a third side plate 5203 and a fourth side plate 5204 are located between the cover plate 560 and the top plate 520; the top plate 520, the first side plate 5201, the second side plate 5202, the third side plate 5203, the fourth side plate 5204 and the cover plate 560 form a closed space, which is used to accommodate the transmission mechanism 300.

[0148] In this embodiment, the enclosed space formed above the top plate 520 protects the transmission mechanism 300 from external interference, preventing transmission failure due to slippage of the transmission belt 310 or wear of the pulley. The box structure composed of the top plate 520, cover plate 560, and side plates increases the structural strength of the top plate 520 and improves its support for other mechanisms. Simultaneously, the enclosed space formed by the top plate 520, side plates, and cover plate 560 solves the problems of easy contamination and noise leakage of the transmission mechanism 300, reduces noise radiation from high-speed rotating components, and improves the equipment's operating environment.

[0149] See some examples. Figure 11 The top surface of the cover plate 560 is provided with a handle assembly 561. The handle assembly 561 can be used by the operator to move the radiator screw parallel locking device to a position aligned with the radiator, facilitating subsequent locking operations. The handle assembly 561 can also be connected to a robotic arm to achieve automated handling.

[0150] See Figure 13 ,for Figure 10 The assembly shown is a cross-sectional view at the bit position;

[0151] In some examples, when the bottom end of the guide tube 550 abuts against the bottom of the radiator 600, see [reference needed]. Figure 13 The bottom end of the bit 210 can be a certain distance from the top of the screw on the radiator 600. At this time, the handle assembly 561 is also used for hand-held operation or robotic gripping. The drive shaft 100, adjustment mechanism 400, and locking mechanism 200 are moved downwards as a whole until the bit 210 contacts the screw on the radiator 600. As the bit 210 gradually tightens the radiator screw, the drive shaft 100, adjustment mechanism 400, and locking mechanism 200 continue to move downwards until the radiator screw is fully tightened. At this time, guided by the telescopic rod 530 of the support mechanism 500, it is ensured that the bit 210 tightens the screw in a vertical direction, preventing screw misalignment, stripping, or other issues.

[0152] See Figure 14 This is a schematic diagram of the connection relationship of the transmission mechanism provided in some embodiments of this application;

[0153] In some examples, the locking mechanism 200 may include a first pulley 230, which may be located at the top of the locking mechanism 200 or on the side near the top; a second pulley 110 is provided on the drive shaft 100; and the transmission mechanism 300 includes a transmission belt 310 connecting the first pulley 230 and the second pulley 110.

[0154] In some examples, the transmission belt 310 can be a double-sided toothed transmission belt; both sides of the transmission belt 310 are provided with tooth grooves, which can cooperate with the toothed structure of the first pulley 230 and the second pulley 110 to achieve the transmission effect.

[0155] Based on this solution, a double-sided toothed drive belt and pulley tooth meshing is adopted to prevent slippage and power loss of the drive belt 310. The double-sided toothed structure improves the transmission efficiency by increasing the number of meshing points. The tooth profile matching design ensures continuous and stable power transmission, especially during high-speed locking, it can still maintain low vibration and low noise, and shorten the average locking time of a single screw.

[0156] In this embodiment, when the drive shaft 100 is driven to rotate by the electric screwdriver, the second pulley 110 rotates and drives the transmission belt 310 to move along the laying direction. The transmission belt 310 then drives the first pulley 230 to rotate, thereby driving the screwdriver bit 210 of the locking mechanism 200 to rotate synchronously, so as to realize the locking or unlocking operation of the radiator screw.

[0157] Based on this solution, stepless torque distribution is achieved by using belt drive, ensuring that the rotation speed of all 210 bits is strictly synchronized, avoiding the speed difference problem caused by manufacturing errors in traditional gear drive, and ensuring the consistency of multi-screw fastening.

[0158] In this embodiment, the position of each locking mechanism 200 can be adjusted by the adjusting mechanism 400, allowing the shape of the transmission belt 310 connecting the first pulley 230 and the second pulley 110 of the locking mechanism 200 to change. To avoid insufficient tension or loosening of the transmission belt 310 due to changes in its shape, in some examples, see... Figure 14 A third pulley 522 can be installed on the top plate 520. The transmission belt 310 connects the first pulley 230, the second pulley 110 and the third pulley 522. The third pulley 522 is used to provide tension to the transmission belt 310. The third pulley 522 and the first pulley 230 are both driven pulleys of the second pulley 110. When the second pulley 110 rotates, the first pulley 230 and the third pulley 522 rotate synchronously.

[0159] In some examples, the third pulley 522 is also provided with a toothed structure that mates with the drive belt 310 to achieve the transmission effect.

[0160] In some examples, when the adjustable range of the locking mechanism 200 is small and the position adjustment of the locking mechanism 200 is insufficient to loosen or disable the transmission belt 310, the embodiments of this application can be implemented without setting the third pulley 522, or other methods can be used to ensure the tension stability of the transmission belt 310.

[0161] See Figure 15This is a schematic diagram of the structure of the top plate provided in some embodiments of this application;

[0162] In some examples, to improve the flexibility of the third pulley 522 in providing tension, the third pulley 522 can be movably mounted on the top plate 520. Specifically, the top plate 520 may have a first groove 523; a first slider 524 is provided in the first groove 523 and is slidably connected to the first groove 523; the third pulley 522 is rotatably connected to the first slider 524.

[0163] Based on this scheme, the first slider 524 slides within the first groove 523 of the top plate. The tension of the transmission belt 310 can be controlled by adjusting the position of the first slider 524, ensuring stable power transmission efficiency.

[0164] In some examples, the first slider 524 may be fixed with a bearing, the inner ring of which is connected to a rotating shaft, and the third pulley 522 is connected to the rotating shaft to achieve the rotation of the third pulley 522.

[0165] In some examples, combined Figure 14 and Figure 15 When the distance between the first pulleys 230 on the four locking mechanisms 200 decreases, the transmission belt 310 tends to loosen. At this time, the third pulley 522 can be moved upward along the first groove 523. Figure 14 The belt 310 can be moved upwards to ensure that it maintains proper tension. Conversely, when the distance between the first pulleys 230 on the four locking mechanisms 200 increases, the belt 310 may become overly taut. In this case, the tension of the belt 310 can be reduced by moving the third pulley 522 downwards.

[0166] Based on this solution, a third pulley 522 is added to work in conjunction with the first pulley 230 and the second pulley 110, thus solving the problem of uneven torque transmission on one side. The third pulley 522 can dynamically compensate for changes in the tension of the transmission belt 310, preventing slippage and extending the life of the transmission mechanism 300.

[0167] In some examples, the number of third pulleys 522 can be one or more, depending on actual needs and the length of the drive belt 310. In this embodiment, two third pulleys 522 are used as an example and should not be construed as a limitation on the number.

[0168] In some examples, the first groove 523 may be a semi-slot formed on the top plate 520 or a through hole extending through the top plate 520.

[0169] See Figure 16 This is a schematic diagram of the structure of the first slider provided in some embodiments of this application;

[0170] In some examples, the first groove 523 is provided with a stepped portion 5231; the first slider 524 is provided with a sliding portion 5241; the sliding portion 5241 cooperates with the stepped portion 5231 to adjust the position of the first slider 524 in the first groove 523.

[0171] See Figure 17 This is a schematic diagram of the locking mechanism in the parallel locking device for radiator screws provided in some embodiments of this application;

[0172] See some examples. Figure 17 In addition to the first pulley 230, the bit 210 and the bearing 220, the locking mechanism 200 also includes an overload protection device 240, which is disposed between the first pulley 230 and the bit 210.

[0173] In this embodiment, the overload protection device 240 may include two toothed sleeves and a spring connecting the two sleeves. The upper sleeve is connected to the first pulley 230, and the lower sleeve is connected to the bit 210. When the torque applied to the locking mechanism 200 is lower than a predetermined value, the sleeves rotate synchronously. When the torque exceeds the predetermined value, the spring is stretched, causing the two sleeves to move relative to each other. The upper sleeve continues to rotate synchronously with the first pulley 230, while the lower sleeve no longer drives the bit 230 to rotate. This design prevents torque overload from damaging the bit 210 or the screws on the radiator.

[0174] In some examples, the locking mechanism 200 also includes a floating shaft 250 located on the outer periphery of the bit 210 near the first pulley 230. The floating shaft 250 allows the bit 210 to automatically adjust its position for better engagement with the screw slot.

[0175] In this embodiment, the floating shaft 250 allows the bit 210 to adaptively adjust its axial direction within a certain angle, compensating for manufacturing tolerances and installation errors of the heat sink, reducing the alignment requirements between the bit 210 and the screw hole, and improving the device's compatibility with irregularly shaped heat sinks.

[0176] The embodiments described above are merely specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made based on the technical solution of this application should be included within the scope of protection of this application.
