Description

Technical Field

[0001] This utility model relates to a big data storage node, specifically a hard disk fast-swap big data storage node, belonging to the field of big data storage technology. Background Technology

[0002] In the field of big data storage, storage node cabinets typically integrate multiple hard drives to meet the demands of massive data storage. Regular maintenance and replacement of these hard drives are crucial for ensuring stable system operation. However, existing storage node hard drive installation structures have significant flaws, causing numerous inconveniences in practical operation.

[0003] Currently, most hard drives are directly fixed inside the cabinet, requiring disassembly to be performed within the cabinet. Because the cabinet must accommodate multiple hard drives and their associated wiring, space is extremely limited, making it difficult for operators to maneuver their hands and tools flexibly. This is especially true when replacing hard drives located deep within or at the edge of the cabinet, where the cramped space often hinders movement, increasing the difficulty of the operation and increasing the risk of secondary malfunctions due to accidental contact with surrounding components. Furthermore, the hard drive disassembly process is cumbersome and time-consuming, requiring multiple steps such as power off, removing the protective cover, loosening the fixing screws (or releasing multiple sets of clips one by one), and unplugging and plugging in data and power cables. Disassembling a single hard drive often takes several minutes. Performing these steps within the limited space of the cabinet further reduces operational efficiency, especially in large-scale data centers where multiple hard drives need to be replaced, resulting in excessively long cumulative time and severely impacting system maintenance efficiency. Summary of the Invention

[0004] This invention provides a hard drive quick-swap big data storage node to solve the problems of limited operating space and inconvenient hard drive removal in existing storage nodes.

[0005] This utility model achieves the above objectives through the following technical solution: a hard disk quick-swap big data storage node, including a storage cabinet, with a cabinet door rotatably connected to the surface of the storage cabinet;

[0006] The storage cabinet has an L-shaped mounting plate that slides inside. Multiple fixed posts are fixedly connected to the surface of the L-shaped mounting plate in a rectangular array. A sliding rod is fixedly connected to one end of each fixed post. A first umbrella-shaped block is fixedly connected to the end of each sliding rod away from the fixed post, and a second umbrella-shaped block is slidably connected to the surface of each sliding rod. A second spring is fixedly connected between the second umbrella-shaped block and the fixed post. A hollow convex frustum is fitted onto the outer side of the first umbrella-shaped block. Symmetrical stepped grooves are formed inside the hollow convex frustum. A T-shaped rod is slidably inserted into the stepped groove and is slidably connected to the hollow convex frustum. A wedge-shaped block is fixedly connected to one end of the T-shaped rod and is slidably connected to the hollow convex frustum, extending into the hollow hole inside the hollow convex frustum. A first spring is fixedly connected between the wedge-shaped block and the stepped groove. A hard drive mounting bracket is fixedly connected to one side surface of the hollow convex frustum, and a hard drive body is housed inside the hard drive mounting bracket.

[0007] As a further improvement of this utility model, strip-shaped heat dissipation grooves are provided on both sides of the storage cabinet.

[0008] As a further embodiment of this utility model: a positioning protrusion is fixedly connected to the side of the second umbrella block near the first umbrella block, and a receiving groove adapted to the positioning protrusion is provided on the side of the first umbrella block near the second umbrella block.

[0009] As a further improvement of this utility model: both sides of the hard drive mounting base are threaded with hand-tightening bolts, and both sides of the hard drive body are provided with screw holes that are compatible with the hand-tightening bolts. The hard drive body is detachably connected to the hard drive mounting base through the hand-tightening bolts.

[0010] As a further embodiment of this utility model: a positioning plate is symmetrically fixedly connected to the surface of the hollow convex frustum, and a positioning rod adapted to the positioning plate is fixedly connected to the corresponding position on the surface of the L-shaped mounting plate, and the positioning plate is slidably sleeved on the surface of the positioning rod.

[0011] As a further embodiment of this utility model: a gap is provided between the initial positions of the first umbrella-shaped block and the second umbrella-shaped block, and a wedge-shaped block is inserted within the gap, and the wedge-shaped block is slidably connected to the first umbrella-shaped block and the second umbrella-shaped block respectively.

[0012] As a further embodiment of this utility model: a fixed seat is fixedly connected to the middle position of the inner bottom surface of the storage cabinet, a screw is rotatably connected between the fixed seat and the inner side wall of the storage cabinet, a sliding seat is threaded onto the surface of the screw, the sliding seat is fixedly connected to the bottom surface of the L-shaped mounting plate, and strip grooves are opened on both sides of the storage cabinet. Sliders are fixedly connected to both sides of the L-shaped mounting plate, and the sliders are slidably set in the strip grooves, and the sliders are slidably connected to the storage cabinet.

[0013] As a further embodiment of this utility model: one end of the screw penetrates the surface of the fixed base and extends to the outside of the fixed base. A handwheel is provided on the outside of the fixed base, and the end of the screw penetrating the surface of the fixed base is fixedly connected to the handwheel.

[0014] As a further improvement of this utility model: the bottom surface of the L-shaped mounting plate is symmetrically and fixedly connected with rollers, and the inner bottom surface of the storage cabinet is symmetrically provided with guide grooves, with the rollers and guide grooves rolling in cooperation.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model utilizes the combination of an L-shaped mounting plate and a sliding structure. The L-shaped mounting plate inside the storage cabinet can slide out of the cabinet as a whole through the guidance of a screw, a sliding seat, a strip groove, and a slider (the screw is driven by a handwheel, which saves even more effort). At the same time, the rollers at the bottom of the L-shaped mounting plate roll in cooperation with the guide groove on the bottom surface of the cabinet, further reducing the resistance to pulling out. This design allows hard drive removal operations that originally had to be completed inside the cabinet to be performed in the open space outside the cabinet, eliminating the limitations of the narrow space inside the cabinet. Operators do not need to reach into the cabinet, avoiding the risks of hand bumps, difficulty in using tools, and accidental contact with surrounding parts.

[0017] 2. During installation, the hard drive mounting bracket with a pre-installed hard drive is inserted into the surface of the first umbrella-shaped block. As the hollow convex frustum moves into the cabinet, the two wedge-shaped blocks, under the pressure of the outer surface of the first umbrella-shaped block, compress the first spring and gradually close. When the distance between the first and second umbrella-shaped blocks is reached, the first spring releases its force, pushing the wedge-shaped blocks into the gap, thus quickly locking the hard drive mounting bracket. The entire process requires no screws or tools; fixation is achieved through a continuous "insertion → compression → locking" action, replacing the cumbersome multi-step installation process of traditional methods and significantly improving installation efficiency in large-scale deployment scenarios.

[0018] The outer surface of the first umbrella-shaped block and the inclined surface of the wedge-shaped block have a self-guiding function. Even when the visibility inside the cabinet is poor, the wedge-shaped block can be guided to slide accurately into the locking position, avoiding fixing failure due to installation deviation and reducing the time cost of repeated operations.

[0019] 3. This invention requires no tools or additional force points for unlocking. Simply pressing the hard drive drives the hollow convex frustum to move backward. The wedge block slides down the inclined surface of the second umbrella-shaped block towards its outer surface, while simultaneously being held in place by the elastic force of the first spring above the wedge block. Then, pulling the hard drive mounting base outward causes the wedge block to move the second umbrella block outward against the tension of the second spring until the second umbrella block is in contact with the first umbrella block. At this point, the wedge block slides out and falls onto the outside of the first umbrella block, completing the unlocking process. The entire process can be completed in the open space outside the cabinet (due to the pull-out design of the mounting base), completely eliminating the limitations of the confined space inside the cabinet and avoiding the problems of hand bumps or tool limitations caused by limited space in traditional disassembly.

[0020] Meanwhile, after the hard drive mounting bracket and the hard drive are removed from the cabinet, all subsequent operations (such as unplugging cables and disassembling hard drives) can be completed in the open space outside the cabinet. Operators do not need to bend over or reach into the cabinet, avoiding problems such as hand bumps and difficulty in using tools due to the small space inside the cabinet. It also reduces the risk of secondary failures caused by accidentally touching other circuits or components inside the cabinet, making the operation more relaxed and safer.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] like Figures 1 to 10 As shown, a hard disk quick-swap big data storage node includes a storage cabinet 1, and a cabinet door 2 is rotatably connected to the surface of the storage cabinet 1.

[0035] An L-shaped mounting plate 4 is slidably installed inside the storage cabinet 1. Multiple fixed posts 5 are fixedly connected to the surface of the L-shaped mounting plate 4 in a rectangular array. A sliding rod 51 is fixedly connected to one end of each fixed post 5. A first umbrella-shaped block 53 is fixedly connected to the end of each sliding rod 51 away from the fixed post 5. A second umbrella-shaped block 54 is slidably connected to the surface of each sliding rod 51. A second spring 52 is fixedly connected between the second umbrella-shaped block 54 and the fixed post 5. A hollow convex frustum 56 is fitted around the outer side of the first umbrella-shaped block 53. Steps are symmetrically formed inside the hollow convex frustum 56. A T-shaped rod 512 is slidably inserted inside the groove 511 and the T-shaped rod 512 is slidably connected to the hollow convex frustum 56. A wedge block 514 is fixedly connected to one end of the T-shaped rod 512. The wedge block 514 is slidably connected to the hollow convex frustum 56 and extends into the hollow hole inside the hollow convex frustum 56. A first spring 513 is fixedly connected between the wedge block 514 and the groove 511. A hard disk mounting base 58 is fixedly connected to one side surface of the hollow convex frustum 56. A hard disk body 59 is disposed inside the hard disk mounting base 58.

[0036] Furthermore, a gap is provided between the initial positions of the first umbrella-shaped block 53 and the second umbrella-shaped block 54, and the wedge-shaped block 514 is inserted within the gap, and the wedge-shaped block 514 is slidably connected to the first umbrella-shaped block 53 and the second umbrella-shaped block 54 respectively.

[0037] When using this utility model, first open the cabinet door 2 on the surface of the storage cabinet 1 to expose the L-shaped mounting plate 4 inside, put the hard disk body 59 into the hard disk mounting base 58 to complete the initial fixation of the hard disk and the mounting base, then hold the hard disk mounting base 58 and align the hollow convex frustum 56 on one side with the first umbrella-shaped block 53 on the L-shaped mounting plate 4 so that the outer surface of the first umbrella-shaped block 53 contacts the wedge-shaped block 514 on the inner side of the hollow convex frustum 56, then push the hard disk mounting base 58 towards the L-shaped mounting plate 4 to drive the hollow convex frustum 56 to slide along the surface of the first umbrella-shaped block 53;

[0038] At this point, the inclined surface of the first umbrella-shaped block 53 presses against the wedge-shaped block 514, forcing the wedge-shaped block 514 to retract into the stepped groove 511, while simultaneously compressing the first spring 513; when the hollow convex frustum 56 completely covers the first umbrella-shaped block 53 and the wedge-shaped block 514 aligns with the gap between the first umbrella-shaped block 53 and the second umbrella-shaped block 54, the first spring 513 resets, pushing the wedge-shaped block 514 into the gap, thus achieving a quick lock between the hard disk mounting base 58 and the L-shaped mounting plate 4; finally, the L-shaped mounting plate 4 is pushed, causing all the installed hard disks to slide into the storage cabinet 1, the cabinet door 2 is closed, and the installation is completed.

[0039] When it is necessary to remove the hard drive, open the cabinet door 2 and pull the L-shaped mounting plate 4 out of the storage cabinet 1 as a whole, so that all the hard drive mounting brackets 58 are exposed to the open space outside the cabinet.

[0040] Next, press the hard drive body 59 (or hard drive mounting base 58) to move the hollow convex frustum 56 toward the L-shaped mounting plate 4. At this time, the wedge block 514 slides outward under the action of the inclined surface of the second umbrella block 54, while compressing the first spring 513 and adhering to the outer surface of the second umbrella block 54. Then, pull the hard drive mounting base 58 in the opposite direction. Under the elastic force of the first spring 513, the wedge block 514 clamps the second umbrella block 54 and moves it away from the fixed post 5, overcoming the tension of the second spring 52, until the second umbrella block 54 coincides with the first umbrella block 53.

[0041] When the second umbrella-shaped block 54 coincides with the first umbrella-shaped block 53, the wedge-shaped block 514 loses its limit and slides out of the outer side of the second umbrella-shaped block 54 under the action of the first spring 513, and falls into the outer surface of the first umbrella-shaped block 53. At this time, the locking between the hollow convex frustum 56 and the L-shaped mounting plate 4 is released, and the hard disk mounting base 58 and the hard disk body 59 can be removed directly.

[0042] Place the removed hard drive mounting bracket 58 outside the cabinet and perform subsequent operations such as unplugging cables and replacing hard drives in the open space to avoid operating inside the cabinet.

[0043] The hard drive can be unlocked and removed from the outside of the cabinet, completely eliminating the constraints of the small space inside the cabinet. This avoids the risk of bumps and knocks when operators reach into the cabinet, and also reduces the probability of accidentally touching internal circuits or components. During installation, the "wedge block 514, first spring 513, and first umbrella block 53" work together to achieve "pushing and locking", eliminating the need for screws and greatly shortening the installation time of a single hard drive. During removal, the lock can be released by "pressing and pulling", saving the tedious steps of unscrewing screws and removing clips.

[0044] It should be noted that: the elastic force of the first spring 513 can ensure that the wedge block 514 is tightly locked between the first umbrella block 53 and the second umbrella block 54, preventing the hard drive from loosening due to vibration during operation; the second spring 52 provides a restoring force for the second umbrella block 54, ensuring the stability of the structure after unlocking.

[0045] The wedge block 514 and the umbrella block have a self-guiding function when their inclined surfaces meet, so that precise alignment is not required during installation and disassembly, reducing wear on components caused by forced operation.

[0046] Furthermore, strip-shaped heat dissipation grooves 3 are provided on both sides of the storage cabinet 1.

[0047] The strip-shaped heat dissipation slots 3 on both sides of the storage cabinet 1 can enhance the air convection inside and outside the cabinet, continuously dissipating the heat generated by the hard drive during installation, operation and removal, avoiding performance degradation or failure of the hard drive due to high temperature, reducing maintenance needs caused by overheating. Especially after the L-shaped mounting plate 4 is pushed into the cabinet, the heat dissipation efficiency in the enclosed space is significantly improved, extending the service life of the hard drive.

[0048] Furthermore, a positioning protrusion 57 is fixedly connected to the side of the second umbrella block 54 near the first umbrella block 53, and a receiving groove 55 adapted to the positioning protrusion 57 is provided on the side of the first umbrella block 53 near the second umbrella block 54.

[0049] Furthermore, both sides of the hard drive mounting base 58 are threaded with hand-tightening bolts 510, and both sides of the hard drive body 59 are provided with screw holes that are compatible with the hand-tightening bolts 510. The hard drive body 59 is detachably connected to the hard drive mounting base 58 through the hand-tightening bolts 510.

[0050] When in use, place the hard drive body 59 into the hard drive mounting bracket 58, align the screw holes on both sides of the hard drive with the hand-tightening bolts 510 on both sides of the mounting bracket, and manually tighten the hand-tightening bolts 510 to firmly fix the hard drive body 59 to the hard drive mounting bracket 58. No tools are required, and the operation is convenient.

[0051] Furthermore, a positioning plate 516 is symmetrically fixedly connected to the surface of the hollow convex frustum 56, and a positioning rod 515 adapted to the positioning plate 516 is fixedly connected to the corresponding position on the surface of the L-shaped mounting plate 4. The positioning plate 516 is slidably sleeved on the surface of the positioning rod 515.

[0052] The positioning plate 516 is slidably sleeved on the surface of the positioning rod 515, providing axial guidance for the push-in / pull-out of the hard drive mounting base 58. The symmetrically distributed positioning plates 516 and positioning rod 515 form lateral support, which can limit the left and right swaying of the hard drive mounting base 58 inside the cabinet or during the pull-out process. Especially when the equipment vibrates during operation, it can reduce the collision between the hard drive body 59 and the mounting base, and between the mounting base and the L-shaped mounting plate 4. At the same time, it eliminates the need to repeatedly adjust the position of the mounting base during installation and disassembly. Simply push and pull smoothly along the direction of the positioning rod 515 to complete the docking or separation, reducing the requirements for operator proficiency and further shortening the disassembly and assembly time of a single hard drive.

[0053] Example 2

[0054] Improvements based on Example 1:

[0055] Furthermore, a fixed base 46 is fixedly connected to the middle position of the inner bottom surface of the storage cabinet 1. A screw 45 is rotatably connected between the fixed base 46 and the inner side wall of the storage cabinet 1. A sliding seat 44 is threaded onto the surface of the screw 45. The sliding seat 44 is fixedly connected to the bottom surface of the L-shaped mounting plate 4. A strip groove 41 is opened on both sides of the storage cabinet 1. A slider 42 is fixedly connected to both sides of the L-shaped mounting plate 4. The slider 42 is slidably disposed in the strip groove 41 and is slidably connected to the storage cabinet 1.

[0056] Furthermore, one end of the screw 45 penetrates the surface of the fixed base 46 and extends to the outside of the fixed base 46. A handwheel 47 is provided on the outside of the fixed base 46, and the end of the screw 45 that penetrates the surface of the fixed base 46 is fixedly connected to the handwheel 47.

[0057] Furthermore, the bottom surface of the L-shaped mounting plate 4 is symmetrically and fixedly connected with rollers 43, and the inner bottom surface of the storage cabinet 1 is symmetrically provided with guide grooves 48, with rollers 43 and guide grooves 48 rolling in cooperation.

[0058] During use, the operator rotates the handwheel 47 on the outside of the storage cabinet 1, which drives the screw 45 between the fixed seat 46 and the inner side wall to rotate; the sliding seat 44 on the surface of the screw 45 moves along the axial direction of the screw 45 due to the threaded engagement, thereby driving the L-shaped mounting plate 4 to move synchronously. At this time, the sliders 42 on both sides of the L-shaped mounting plate 4 slide along the strip groove 41 of the storage cabinet 1, and the rollers 43 at the bottom roll along the guide groove 48 on the inner bottom surface. The three work together to ensure that the L-shaped mounting plate 4 is pulled out smoothly from inside the cabinet until the hard drive mounting base 58 is completely exposed outside the cabinet. After the hard drive is installed or removed, the handwheel 47 is turned in the opposite direction, and the screw 45 drives the sliding seat 44 to move in the opposite direction. Under the guidance of the sliders 42 and the strip groove 41, and the rolling cooperation of the rollers 43 and the guide groove 48, the L-shaped mounting plate 4 is smoothly retracted into the storage cabinet 1 until it is completely retracted. This allows the hard drive removal operation, which originally had to be completed inside the cabinet, to be carried out in the open space outside the cabinet. This eliminates the limitation of operation caused by the narrow space inside the cabinet. Operators do not need to reach into the cabinet, avoiding the risk of hand bumps, difficulty in using tools, and accidental contact with surrounding parts.

[0059] Working principle: In use, open cabinet door 2, turn handwheel 47 to drive screw 45 to rotate, causing sliding seat 44 to move axially along screw 45, driving L-shaped mounting plate 4 to be smoothly pulled out from storage cabinet 1 through slider 42 (along strip groove 41) and roller 43 (along guide groove 48) until the hard drive installation area is fully exposed. At this time, the strip heat dissipation grooves 3 on both sides of storage cabinet 1 begin to enhance air convection, providing a heat dissipation basis for subsequent operations;

[0060] Next, place the hard drive body 59 into the hard drive mounting bracket 58, and tighten the hand-tightening bolts 510 on both sides of the hard drive mounting bracket 58 so that they engage with the threaded holes of the hard drive body 59. The mechanical locking achieves a detachable fixation of the two, ensuring that the hard drive does not wobble during movement. No tools are required, and the operation is simple.

[0061] Then, holding the hard drive mounting base 58, align the hollow convex frustum 56 with the first umbrella-shaped block 53 on the L-shaped mounting plate 4. The positioning plate 516 slides along the positioning rod 515, providing axial guidance for the overall docking and ensuring that the positioning protrusion 57 of the second umbrella-shaped block 54 is precisely aligned with the receiving groove 55 of the first umbrella-shaped block 53. Push the hard drive mounting base 58 towards the first umbrella-shaped block 53. The inclined surface of the first umbrella-shaped block 53 presses against the wedge block 514, forcing the wedge block 514 to compress the first spring 513 and retract into the stepped groove 511. When the wedge block 514 is aligned with the initial gap between the first umbrella-shaped block 53 and the second umbrella-shaped block 54, the first spring 513 resets, pushing the wedge block 514 into the gap. The limiting effect of the wedge block 514 and the first umbrella-shaped block 53 is used to quickly lock the hard drive mounting base 58 with the L-shaped mounting plate 4.

[0062] Next, turn the handwheel 47 in the opposite direction, and push the L-shaped mounting plate 4 back into the storage cabinet 1 along the guide structure, close the cabinet door 2, and the strip heat dissipation slot 3 continues to dissipate heat for the running hard drive;

[0063] When it is necessary to remove and replace the hard drive, open the cabinet door 2, turn the handwheel 47 to pull out the L-shaped mounting plate 4, so that all hard drive mounting brackets 58 are exposed to the open space outside the storage cabinet 1, avoiding the limitation of space inside the cabinet;

[0064] Next, press the hard drive body 59 (or hard drive mounting base 58), which will cause the hollow convex frustum 56 to move towards the L-shaped mounting plate 4. The wedge block 514 will slide outward under the action of the inclined surface of the second umbrella block 54, compress the first spring 513 and fit against the outer surface of the second umbrella block 54, and pull the hard drive mounting base 58 in the opposite direction. The wedge block 514 will clamp the second umbrella block 54 under the elastic force of the first spring 513, and drive it to move away from the fixed post 5 against the tension of the second spring 52 until the second umbrella block 54 coincides with the first umbrella block 53.

[0065] When the second umbrella-shaped block 54 coincides with the first umbrella-shaped block 53, the wedge-shaped block 514 loses its limit and slides out of the outside of the second umbrella-shaped block 54 under the action of the first spring 513, falling into the outer surface of the first umbrella-shaped block 53. The lock is released, and the hard disk mounting bracket 58 and the hard disk body 59 can be removed as a whole.

[0066] Through the coordinated operation of screw 45, handwheel 47, slider 42 (in conjunction with strip groove 41), and roller 43 (in conjunction with guide groove 48), the L-shaped mounting plate 4 can be pulled out as a whole, allowing the hard drive installation and removal to be completed entirely outside the storage cabinet 1, completely eliminating space limitations. Furthermore, the quick-release structure achieves "pushing in to lock, pressing and pulling to unlock." All locking and unlocking steps are completed by "pushing, pressing, pulling, and tightening the bolts," requiring no professional tools and lowering the operational threshold. All subsequent operations (such as disconnecting cables and disassembling hard drives) can be completed in the open space outside the cabinet. Operators do not need to bend over or reach into the cabinet, avoiding problems such as hand bumps and difficulty in using tools due to the limited space inside the cabinet. It also reduces the risk of secondary malfunctions caused by accidentally touching other circuits or components inside the cabinet, making the operation more relaxed and safer.
