Description

Technical Field

[0001] This utility model belongs to the field of mechanical fixing technology of data storage devices, and in particular relates to a self-locking structure of a hard disk quick-release device. Background Technology

[0002] In recent years, with the rapid popularization of data centers, edge computing and smart terminals, replaceable hard drive modules have become the standard configuration of commercial all-in-one machines and industrial control chassis due to their advantages such as "tool-free on-site expansion, rapid maintenance and data security isolation". The concept of "quick hard drive removal" has emerged as a result.

[0003] Existing quick-release hard drive structures mainly fall into two categories: one type still uses traditional screw locking—the hard drive tray has pre-drilled screw holes at the tail or side wall, and after insertion into the guide rail, it is tightened with one or two screws. When disassembling, a screwdriver must be used to loosen the screws before pulling out the hard drive; the other type attempts to eliminate tools by adding a flip-up or sliding cover at the door, with push rods and connecting rods arranged inside the compartment. When the hard drive is inserted, the tail of the hard drive pushes the push rod, which drives the cover to close simultaneously. The edge of the cover engages with the door frame to lock it in place. When disassembling, the cover is manually pulled open, and the connecting rod moves in the opposite direction to push the hard drive out.

[0004] However, all of the above solutions have obvious shortcomings: although screw fixing provides stable locking force, it still requires special tools for disassembly and assembly, and the loss of screws or stripping of threads are frequent on site, resulting in low maintenance efficiency; although the cover-push rod linkage structure can be operated by hand, it requires additional connecting rods, torsion springs, shafts and buckles, resulting in a large number of parts, complex molds, and high costs. In addition, the linkage mechanism occupies the internal height of the compartment, which increases the thickness of the equipment. At the same time, the locking force relies only on the thin-walled engagement between the plastic cover and the door frame. Long-term vibration or drops can easily cause the buckles to wear and break, and the hard drive may still come loose, resulting in insufficient reliability. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, one aspect of this application proposes a self-locking structure for a hard drive quick-release device, comprising: Hard drive bay, the hard drive bay being mounted on the chassis; A hard drive tray, which is slidably disposed in the hard drive compartment; A locking component, disposed on the housing, for preventing the hard drive tray from dislodging from the hard drive bay; the locking component includes: A sliding trigger is slidably disposed on the body; a trigger limiter is provided on the sliding trigger. A rotating component is rotatably mounted on the machine body; one end of the rotating component extends out of the machine body and is provided with a limit knob; the other end of the rotating component away from the limit knob is located inside the machine body and is provided with a rotation trigger. A torsion spring, which is disposed on the rotating member, is used to drive the rotating member to rotate; The locking component has a first state and a second state: In the first state, the trigger limiter interferes with the rotation triggerer to overcome the torque of the torsion spring and keep the rotating member stationary, so that the limit knob is in the open position, allowing the hard disk tray to freely enter and exit the hard disk compartment; In the second state, the hard drive tray is inserted into the hard drive bay and pushes the sliding trigger. The sliding trigger causes the trigger limiter to move away from the rotating trigger to release the interference, and the torsion spring drives the rotating member to rotate, turning the limit knob from the open position to the locked position and pressing it against the hard drive tray, thereby preventing the hard drive tray from moving in the pull-out direction.

[0007] In this technical solution, the structural design utilizes a closed-loop linkage between a sliding trigger, a rotating component, and a torsion spring. The hard drive automatically locks itself the moment it is pushed into place. Reversing the lock can be achieved simply by manually rotating the limit knob, without the need for screws or auxiliary tools. The locking force is continuously provided by the metal torsion spring, unaffected by vibration, temperature changes, or plastic creep. The limit knob continuously blocks the hard drive tray, thus maintaining its fixed position over a long period. This fundamentally solves the problems of loose screws and worn clips, significantly reducing maintenance time for on-site hard drive replacement and significantly improving structural reliability.

[0008] In some embodiments, the rotating trigger is provided with a limiting groove; in the first state, the trigger limiting member is disposed in the limiting groove.

[0009] In the technical solution, the structure design adds a limiting groove to the rotating trigger, and the trigger limiting component is clamped by both sides of the groove wall, forming a more tight fit. No matter which direction the impact or vibration is from, the trigger limiting component is blocked by the groove wall and cannot slide, thus maintaining accurate interference with the rotating trigger, significantly improving the overall limiting effect and preventing false locking due to limiting failure.

[0010] In some embodiments, the sliding trigger is provided with a reset spring; in the second state, the trigger limiter pushes the reset spring so that the reset spring generates a spring force that pushes the sliding trigger in a direction outside the body.

[0011] In the technical solution, the structural design allows the reset spring to immediately push the sliding trigger back to its original position after the hard drive is removed, and the trigger limiter can then re-enter the interference position, and the entire locking assembly automatically returns to the insertion state; maintenance personnel do not need to manually turn the lever or confirm the position, and can continuously hot-swap multiple hard drives, making the operation process more seamless and smooth.

[0012] In some embodiments, the reset spring is a compression spring and is sleeved on the sliding trigger; the sliding trigger passes through the sliding seat provided on the body, one end of the compression spring presses against the sliding seat, and the other end presses against the trigger limiting member.

[0013] In this technical solution, the structural design places a compression spring on the sliding trigger and between the sliding seat and the trigger limiting member, forming a built-in elastic reset structure. The sliding seat provides a directional slide for the sliding trigger, and the axis of the compression spring always coincides with the sliding direction, avoiding jamming or uneven wear caused by lateral forces. The compression spring can stably push the sliding trigger back to the initial position, ensuring that the trigger limiting member and the rotating trigger re-establish reliable interference, thereby continuously maintaining accurate limiting function and significantly improving reset consistency and long-term limiting effect.

[0014] In some embodiments, the sliding trigger has a cut surface that adheres to the surface of the body to prevent the sliding trigger from rotating.

[0015] In the technical solution, the structural design uses the anti-rotation pair formed by the fit of the cross-section with the plane of the machine body to ensure that the sliding trigger can only slide along the axis and cannot rotate around the axis, thus ensuring that the trigger limiter and the rotating trigger always remain in the same phase, and the locking-unlocking correspondence between the two remains accurate, and the mechanical cycle stability is guaranteed.

[0016] In some embodiments, the outer end of the hard drive tray is provided with an end plate; in the second state, the end plate presses against the sliding trigger and closes the port of the hard drive compartment, and the limiting knob presses against the end plate.

[0017] In this technical solution, the structural design uses the hard drive tray end plate as a door cover, which completely covers the hard drive bay port after insertion, eliminating the need for separate doors, hinges, and connecting rods. This reduces the number of components and also eliminates the thickness space occupied by the door. The appearance is neat and without openings, which helps to improve the overall sealing and aesthetics of the machine.

[0018] In some embodiments, in the second state, the limiting knob and the body clamp and fix the end plate.

[0019] In the technical solution, the structure is designed so that after the limit knob is rotated to the locked position, it clamps the end plates with the front and rear of the machine body to form a closed structure similar to a latch. No matter how the equipment is moved or vibrated, the end plates are continuously clamped, the hard disk tray cannot be moved back, the locking effect is more secure, and the anti-loosening ability is significantly enhanced.

[0020] In some embodiments, the end face of the limiting knob near the rotating trigger is provided with an inclined surface, which, under the sliding engagement of the inclined surface with the hard disk tray, causes the limiting knob to push the hard disk tray to move into the hard disk compartment.

[0021] In the technical solution, this structural design can increase the width of the opening between the limit knob and the machine body, ensuring that the limit knob can be smoothly rotated to the limit fixing position aligned with the hard drive tray. Furthermore, the inclined surface of the end face of the limit knob applies a continuing inward pushing force to the hard drive tray while rotating, making the connection between the hard drive connector and the adapter more compact, stabilizing the contact resistance, and thus improving the reliability of signal transmission.

[0022] In some embodiments, the rotating component is disposed on a rotating seat disposed on the machine body; the torsion spring is sleeved on the rotating component and is respectively connected to the rotating seat and the rotation trigger.

[0023] In the technical solution, the structural design places the torsion spring on the rotating part and hides it inside the rotating seat. The radial dimensions are compact and the layout space is small. The two ends of the torsion spring are fixed on the stationary seat and the moving part respectively. The output torque is stable and the direction is unique, ensuring that the locking angle is the same every time, avoiding the phenomenon of incomplete rotation, and improving mechanical consistency.

[0024] In some embodiments, in the first state, the sliding trigger is located inside the housing; in the second state, the trigger portion provided on the hard disk tray extends into the housing so that the trigger portion pushes the sliding trigger.

[0025] In the technical solution, the structural design hides the sliding trigger inside the machine body. The sliding trigger is only contacted and pushed when the insertion depth is sufficient. There are no protruding buttons on the outside of the sliding trigger, which reduces the risk of accidentally triggering the locking component to lock due to accidental contact.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figures 1 to 8 As shown in the schematic embodiment of the self-locking structure of the hard disk quick-release device of this utility model, the self-locking structure of the hard disk quick-release device includes a hard disk compartment 1, a hard disk bracket 2, and a locking component 3.

[0034] The hard drive bay 1 is typically a hollow shell, usually fixedly installed inside the device body 4, or integrated into the body 4. The hard drive bay 1 typically has a port 101 at one end, which usually extends out of the body 4 or is flush with the outer surface of the body 4, allowing the hard drive to be inserted into the hard drive bay 1 through the port 101. This connects the connector on the hard drive to the adapter inside the hard drive bay 1, enabling communication between the hard drive and the device.

[0035] The hard drive tray 2 is typically a flat plate structure, with the hard drive fixed to it by screws. The hard drive tray 2 is usually made of thermally conductive material, and its surface is typically coated with thermally conductive silicone. This silicone is attached to the lower surface of the hard drive, efficiently transferring the heat generated during hard drive operation to the hard drive tray 2, and then dissipating it through the tray 2, achieving efficient heat dissipation. The inner surface of the hard drive bay 1 is usually equipped with a guide rail structure. When the hard drive tray 2 is inserted into the hard drive bay 1, it slides gradually along the guide rail structure into the bay 1, smoothly inserting the hard drive into the bay 1.

[0036] The locking component 3 is mounted on the housing 4 to prevent the hard disk tray 2 from detaching from the hard disk compartment 1, thereby limiting and fixing the hard disk tray 2. The locking component 3 includes a sliding trigger 31, a rotating component 32, and a torsion spring 33.

[0037] The sliding trigger 31 is slidably mounted on the body 4, allowing it to move along the body 4. The hard disk drive 1 is typically positioned along a first direction, with one end having a port 101 and the other end closed. The sliding trigger 31 is typically a rod and is positioned along the first direction. The body 4 has a sliding seat 401 with a sliding hole. The sliding trigger 31 is positioned in the sliding hole and typically passes through the sliding seat 401, thus moving along the first direction under the guidance of the sliding hole.

[0038] Furthermore, a trigger limiter 311 is provided on the sliding trigger 31. The trigger limiter 311 is typically connected to the sliding trigger 31 at one end, and extends radially away from the sliding trigger 31 at the other end, so that the trigger limiter 311 protrudes from the side surface of the sliding trigger 31.

[0039] The rotating component 32 is rotatably mounted on the body 4, allowing it to rotate within the body 4. The rotating component 32 typically has a shaft portion, with a shaft hole on the body 4 into which the shaft portion is positioned, enabling the rotating component 32 to rotate within the constraint of the shaft hole. The rotating component 32 is typically positioned along a first direction, with its inner end located inside the body 4 and its outer end extending outside the body 4. A limit knob 321 is located at the outer end of the rotating component 32, and a rotation trigger 322 is located at its inner end. The outer diameters of both the limit knob 321 and the rotation trigger 322 are typically larger than the shaft portion, causing both to protrude radially on the side surface of the rotating component 32.

[0040] The torsion spring 33 is disposed on the rotating member 32 and is usually connected to the body 4 and the rotating member 32. When the rotating member 32 rotates, the torsion spring 33 undergoes elastic deformation, accumulates elastic force to provide torque for the rotating member 32, and realizes the drive for the rotation of the rotating member 32.

[0041] The locking component 3 has a first state and a second state. The first state is the unlocked state, and the second state is the locked state.

[0042] See Figures 2 to 4 In the first state, the hard drive tray 2 is either outside the hard drive bay 1 or partially inside the hard drive bay 1 and not fully installed. The torsion spring 33 is in an elastic deformation state. The trigger limit member 311 contacts the rotation trigger member 322, causing the trigger limit member 311 to interfere with the rotation trigger member 322. The trigger limit member 311 overcomes the torque of the torsion spring 33 to prevent the rotation trigger member 322 from rotating, keeping the rotating member 32 stationary. At the same time, the limit knob 321 is in the open position, so that the limit knob 321 is completely on one side of the hard drive tray 2 and is not partially opposite to the hard drive tray 2 in the first direction. It will not obstruct the hard drive tray 2 from entering or leaving the hard drive bay 1. At this time, the hard drive tray 2 can freely enter and leave the hard drive bay 1.

[0043] See Figures 5 to 8 In the second state, the hard drive tray 2 is inserted into the hard drive compartment 1 and pushes the sliding trigger 31. The sliding trigger 31 causes the trigger limiter 311 to move away from the contact with the rotating trigger 322, thereby eliminating the obstruction of the trigger limiter 311 to the rotation of the rotating trigger 322. The torsion spring 33 drives the rotating member 32 to rotate, so that the limit knob 321 rotates from the open position to the locked position. In the locked position, the limit knob 321 is partially opposite to the hard drive tray 2 in the first direction, preventing the hard drive tray 2 from moving in the pull-out direction. This prevents the limit knob 321 from moving the hard drive tray 2 out of the body 4 and keeps it stably in the hard drive compartment 1, realizing the self-locking of the hard drive quick installation.

[0044] When it is necessary to remove the hard drive from the housing 4, manually turn the limit knob 321 to move the portion of the limit knob 321 away from the part of the hard drive tray 2 that is opposite to it in the first direction. This removes the obstruction of the limit knob 321 from the outward movement of the hard drive tray 2 in the first direction, allowing the hard drive tray 2 to be pulled outward along with the hard drive from the hard drive bay 1. At the same time, move the sliding trigger 31 outward to the position in the first state, so that the trigger limit 311 resumes contact and interference with the rotation trigger 322, resetting the locking component 3 to the unlocked state so that it can self-lock when the hard drive is reinstalled.

[0045] This structural design allows the hard drive tray 2 to contact and push the sliding trigger 31 when it is inserted into the hard drive bay 1 along with the hard drive tray 2 and installed in place. This enables the sliding trigger 31, the rotating part 32, and the torsion spring 33 to trigger in a coordinated manner, instantly and automatically locking the limit knob 321 on the hard drive tray 2, thus automatically locking the hard drive itself. When removing the hard drive in reverse, simply rotate the limit knob 321 by hand to release the lock on the hard drive tray 2, allowing the hard drive to be pulled out. No knob screws or auxiliary tools are needed during the self-locking and disassembly process, making the hard drive removal and replacement operation highly efficient. In addition, when the hard drive is locked, the limit knob 321 is difficult to rotate without external force due to the elastic force of the torsion spring 33. This allows the torsion spring 33 to continuously provide support for the limit knob 321, keeping the limit knob 321 in the locked state. The limit knob 321 continuously blocks the hard drive tray, thus maintaining the limit and fixation of the hard drive tray for a long time. The structural reliability is significantly improved, fundamentally solving the problems of easy loosening of screws and easy wear of clips in the locking structure of the prior art.

[0046] Furthermore, in order to limit the limit knob 321 to the locked position during hard drive self-locking and to prevent the limit knob 321 from losing its positional and movement restriction over the hard drive tray 2 in the first direction due to excessive rotation driven by the torsion spring 33, the body 4 is provided with a rotation limit member in the rotation direction of the rotating member 32. When the limit knob 321 is in the locked position, the rotation limit member contacts the rotating member 32 to prevent it from rotating further.

[0047] In some embodiments, a limiting groove 323 is provided on the rotary trigger 322. In the first state, the trigger limiting member 311 is located in the limiting groove 323. More specifically, the limiting groove 323 is usually located at an edge position away from the rotation center of the rotary trigger 322, so that the trigger limiting member 311 can extend into the limiting groove 323 in a direction perpendicular to the first direction. This allows the rotary trigger 322 and the trigger limiting member 311 to overlap in a direction perpendicular to the first direction in the first state, making the locking assembly 3 more compact and occupying less space. In order to allow the sliding trigger 31 to move along the first direction so that the trigger limiting member 311 can disengage from the limiting groove 323 and eliminate its interference with the rotary trigger 322, the limiting groove 323 usually penetrates the rotary trigger 322 along the first direction. The limiting groove 323 may also be provided on the inner surface of the rotary trigger 322 in the first direction, with the trigger limiting member 311 inserted into the limiting groove 323 from the inside to the outside along the first direction.

[0048] This structural design allows the trigger limiter 311 to be clamped on both sides of the trigger limiter 311 in the rotation direction of the rotating triggerer 322 when the trigger limiter 311 is in the limiter groove 323, forming a more stable interference connection. Under impact or vibration, the trigger limiter 311 is blocked by the groove wall of the limiter groove 323, thereby maintaining accurate interference with the rotating triggerer 322, significantly improving the overall limiting effect, preventing false locking due to limiter failure, and ensuring smooth hard drive installation and self-locking.

[0049] In some embodiments, a return spring 34 is provided on the sliding trigger 31. In the second state, the trigger limiter 311 pushes the return spring 34, so that the return spring 34 generates a spring force that pushes the sliding trigger 31 outward from the body 4. When unlocking and removing the hard drive, the limit knob 321 is rotated to the open position, the hard drive tray 2 is pulled out of the hard drive bay 1, the inward support of the hard drive tray 2 on the sliding trigger 31 in the first direction is eliminated, and the sliding trigger 31 is pushed outward in the first direction, so that the trigger limiter 311 resumes contact and interference with the rotation trigger 322, and the locking assembly 3 is restored to the first state. Furthermore, in the second state, the trigger limiter 311 is normally pressed against the surface of the rotary trigger 322 by the push of the return spring 34. When the rotary trigger 322 is rotated to the open state by the limit knob 321, a portion of the rotary trigger 322 moves away from the position opposite to the trigger limiter 311 in the first direction, eliminating the restriction on the movement of the sliding trigger 31 in the first direction and restoring the locking assembly 3 to the first state. When the rotary trigger 322 is provided with a limit groove 323, when the rotary trigger 322 is rotated to the open position, the limit groove 323 aligns with the trigger limiter 311 in the first direction, so that the trigger limiter 311 enters the limit groove 323 under the push of the return spring 34, restoring its interference with the rotary trigger 322.

[0050] This structural design allows the reset spring 34 to immediately push the sliding trigger 31 back to its original position after the hard drive is removed, and the trigger limit member 311 can then re-enter the interference position. The entire locking assembly 3 automatically returns to the insertion state so that the hard drive can be installed again. Maintenance personnel do not need to manually turn the lever or confirm the position, and multiple hard drives can be hot-swapped continuously, making the operation process more seamless and smooth.

[0051] In some embodiments, the return spring 34 is a compression spring and is sleeved on the sliding trigger 31. The sliding trigger 31 passes through the sliding seat 401 provided on the body 4, and one end of the compression spring presses against the sliding seat 401, while the other end presses against the trigger limiting member 311. The sliding seat 401 is typically located inside the trigger limiting member 311 in the first direction. In the second state, the locking assembly 3 is in the second state, with the sliding trigger 31 pushed inward by the hard disk tray 2, the distance between the sliding seat 401 and the trigger limiting member 311 decreases, and the return spring 34 is compressed. This structural design places a compression spring on the sliding trigger 31 and between the sliding seat 401 and the trigger limiter 311, forming a built-in elastic reset structure. The sliding seat 401 provides a directional slide for the sliding trigger 31, and the sliding trigger 31 provides radial support for the compression spring, so that the axis of the compression spring always coincides with the sliding direction, avoiding jamming or uneven wear caused by lateral force. The compression spring can stably push the sliding trigger 31 back to the initial position, ensuring that the trigger limiter 311 and the rotary trigger 322 re-establish reliable interference, thereby continuously maintaining accurate limit function and significantly improving reset consistency and long-term limit effect.

[0052] In some embodiments, the sliding trigger 31 is provided with a cross-section, which is typically located on the side surface of the sliding trigger 31. The cross-section is attached to the surface of the body 4, so that one side of the sliding trigger 31 makes surface contact with the body 4, and the cross-section slides on the surface of the body 4 when the sliding trigger 31 moves along the first direction. This structural design, through the anti-rotation pair formed by the cross-section fitting with the plane of the body 4, ensures that the sliding trigger 31 can only slide along the axial direction and cannot rotate around the axis, avoiding phase shift between the trigger limit member 311 and the rotating trigger 322, ensuring that the trigger limit member 311 and the rotating trigger 322 always remain in the same phase, the sliding trigger 31 can return to the position of the first state, and the trigger limit member 311 can be reset to the position that would interfere with the rotating trigger 322. The locking-unlocking correspondence between the trigger limit member 311 and the rotating trigger 322 remains accurate, and the mechanical cycle stability is guaranteed.

[0053] In some embodiments, an end plate 201 is provided at the outer end of the hard drive tray 2. In the second state, the end plate 201 presses against the sliding trigger 31 and closes the port 101 of the hard drive compartment 1, and the limiting knob 321 presses against the end plate 201. This structural design uses the end plate 201 of the hard drive tray 2 as a door cover, completely covering the port 101 of the hard drive compartment 1 after insertion, eliminating the need for separate doors, hinges, and connecting rods, reducing the number of components and eliminating the need for a separate door to occupy the thickness space of the body 4, making the appearance of the body 4 neater. In addition, the surface area of ​​the end plate 201 is usually larger than the port 101 of the hard drive compartment 1, thus providing more effective coverage, which helps to improve the overall sealing and aesthetics of the machine. Furthermore, the end plate 201 can easily extend to one side of the hard drive compartment 1, thereby triggering the sliding trigger 31 and cooperating with the limiting knob 321 to lock, ensuring that the locking component 3 is entirely located on one side of the hard drive compartment 1, avoiding the locking component 3 occupying the space inside the hard drive compartment 1 for storing the hard drive.

[0054] In some embodiments, in the second state, the limiting knob 321 and the body 4 clamp and fix the end plate 201. This structural design, after the limiting knob 321 is rotated to the locked position, clamps the end plate 201 with the body 4, forming a latch-like closed structure. This more firmly limits the hard drive tray in both inward and outward directions. Regardless of how the device is moved or vibrated, the end plate 201 is continuously clamped, and the hard drive tray 2 cannot move. The locking effect is more secure, and the resistance to loosening is significantly enhanced. Furthermore, the tight contact between the limiting knob 321 and the end plate 201 allows the friction between them to keep the limiting knob 321 stably in the locked state.

[0055] In some embodiments, the end face of the limiting knob 321 near the rotation trigger 322 is provided with a slope 324, so that when the locking assembly 3 is in the first state, the distance between the portion of the limiting knob 321 near the hard drive tray 2 and the body 4 is larger. Furthermore, when the locking assembly 3 triggers the self-locking mechanism, the larger distance ensures that the limiting knob 321 can rotate smoothly towards the hard drive tray 2 without being blocked by the hard drive tray 2 and unable to rotate to the locked state. During the process of the limiting knob 321 rotating to the locked state, the slope 324 slides in contact with the surface of the hard drive tray, and through the cooperation of both, the limiting knob 321 pushes the hard drive tray 2 towards the hard drive bay 1, ultimately firmly pressing the outer end of the hard drive tray 2 inward in the locked state.

[0056] This structural design increases the width of the opening between the limit knob 321 and the housing 4, ensuring that the limit knob 321 can rotate smoothly to the limit fixing position aligned with the hard disk tray 2. Furthermore, the inclined surface 324 on the end face of the limit knob 321 applies a continuing inward pushing force to the hard disk tray 2 while rotating, making the connection between the hard disk connector and the adapter more compact, stabilizing the contact resistance, and thus improving the reliability of signal transmission.

[0057] In some embodiments, the rotating member 32 is disposed on a rotating seat 402 provided on the body 4. The rotating seat 402 is typically provided with a shaft hole, through which the rotating member 32 passes to achieve its rotation. The torsion spring 33 is sleeved on the rotating member 32 and is connected to the rotating seat 402 and the rotation trigger member 322 respectively. This structural design, by sleeved on the rotating member 32 and concealed inside the rotating seat 402, results in a compact radial dimension and small layout space for the locking assembly 3. In addition, with both ends of the torsion spring 33 fixed to the stationary seat and the moving member respectively, the output torque is stable and directional, ensuring that the locking angle is the same each time, avoiding incomplete rotation, and improving mechanical consistency.

[0058] In some embodiments, in the first state, the sliding trigger 31 is located inside the housing 4; in the second state, the trigger part 202 provided on the hard disk tray 2 extends into the housing 4, so that the trigger part pushes the sliding trigger 31. This structural design hides the sliding trigger 31 inside the housing 4. Only when the hard disk is inserted into the hard disk bay 1 to a sufficient depth can the trigger part on the hard disk tray 2 extend into the housing 4, contact and push the sliding trigger 31, trigger the locking component 3, and realize the self-locking of the hard disk. The sliding trigger 31 has no protruding button on the outside, reducing the risk of accidentally triggering the locking component 3 to lock due to accidental contact, and avoiding the hard disk tray 2 being blocked by the limit knob 321 and unable to be inserted into place, thus ensuring smooth installation of the hard disk.

[0059] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
