Description

Technical Field

[0001] This utility model relates to the field of card slot dust prevention technology, specifically to a cloud storage card slot dust prevention device. Background Technology

[0002] Cloud storage is a type of storage where data is stored on a remote server cluster and accessed online. Existing cloud storage servers can store large amounts of data for extended periods using solid-state drives (SSDs) under high load, improving data security and reliability.

[0003] Existing hard drive cages use an array of multiple hard drive bays and have internal cooling fans to accelerate air circulation within the cages, thereby cooling the working hard drives. However, most existing hard drive bays only have dust filters directly fixed to the bay doors for dust prevention. Although this can remove some dust, some mobile dust can still be directly introduced into the hard drive bays through the dust filters. Furthermore, the dust filters are fixed and inconvenient to remove. During the process of cleaning the dust on the surface of the dust filters, the dust can be vibrated and re-entrained, increasing the probability of dust being introduced into the hard drive bays. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that relying solely on a dust filter results in poor dust removal efficiency, and the fixed connection of the dust filter makes it inconvenient to disassemble and maintain.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a cloud storage card slot dustproof device, including a hard drive cage, a card slot that can cooperate with the hard drive is connected to the hard drive cage, a grid is connected to the front side of the hard drive cage near the card slot, a door is hinged to the front opening of the hard drive cage by a torsion spring, a dust filter screen is detachably connected to the door, an opening and closing component that can open and close the door is connected to one side of the hard drive cage, the grid, the door and the hard drive cage enclose a dustproof cavity, and a plurality of dust blocking components that can block dust are connected inside the dustproof cavity.

[0008] Furthermore, the dust filter is circumferentially connected to a support frame, and the door is provided with a through hole. The through hole mates with the support frame. The support frame is circumferentially connected with a limiting groove. The through hole is circumferentially connected with several grooves. A limiting block is connected to the groove by a first spring. The free end of the limiting block mates with the limiting groove for limiting. A limiting ring plate is connected to the side of the door near the dust-proof chamber at the through hole. By mates the support frame with the dust filter with the through hole until the support frame abuts against the limiting ring plate, the limiting block slides out of the groove under the elastic force of the first spring and engages with the limiting groove at its end for limiting.

[0009] Furthermore, the limiting block is a spherical or triangular structure, which allows the limiting block to be driven by the support frame under external force, causing the limiting block to slide into the groove. When the support frame abuts against the limiting ring plate, the support frame can no longer move. At this time, the limiting block slides out of the groove under the elastic force of the first spring and is limited and matched with the limiting groove at its end.

[0010] Furthermore, the opening and closing assembly includes a locking block connected to the door away from the hinge. The locking block has a right-angled triangular structure. The hard disk cage is connected to a locking assembly that can be positioned in the locked state of the door and an unlocking assembly that can unlock the locking assembly. The locking assembly includes a drive cavity connected to the hard disk cage. A locking tongue is slidably connected in the drive cavity. One end of the locking tongue cooperates with the locking block for limiting the position. A second spring is connected between the other end of the locking tongue and the drive cavity. When the door rotates to close around the hinge, the locking block drives the locking tongue to slide into the drive cavity until the locking block and the locking tongue are no longer in contact. At this time, the locking block and the locking tongue cooperate to limit the position, thereby closing the door.

[0011] Furthermore, the unlocking component includes a pressure groove connected to the front side of the hard drive cage. A pressure plate is slidably connected within the pressure groove. Several third springs are connected between the pressure plate and the pressure groove. A driving block is connected to the pressure plate. The driving block is a right-angled triangle or a right-angled trapezoid. A U-shaped plate is connected to the latch. The other end of the driving block extends into the driving cavity and abuts against one end of the U-shaped plate on its inclined surface. By pressing the pressure plate, the third spring is compressed and stores force. The pressure plate drives the driving block to extend into the driving cavity. The inclined surface on the driving block drives the U-shaped plate to slide the latch into the driving cavity. At this time, the second spring is compressed and stores force until the latch no longer limits the locking block. At this time, the door opens.

[0012] Furthermore, a groove is provided at one end of the U-shaped plate that abuts against the inclined surface of the driving block, and a roller is rotatably connected in the groove. The roller abuts against the inclined surface of the driving block circumferentially, which helps to reduce friction and facilitates the driving block to drive the U-shaped plate.

[0013] Furthermore, the dust-blocking assembly includes an array of several dust-blocking units connected within the dust-blocking chamber. Each dust-blocking unit is a figure-eight dust-blocking plate that runs horizontally through the dust-blocking chamber. The bottom of the figure-eight dust-blocking plate is connected to the dust-blocking chamber, and the top of the figure-eight dust-blocking plate is connected to the dust-blocking chamber. Some dust is introduced into the dust-blocking chamber through the dust-blocking mesh. Due to the arrangement of the figure-eight dust-blocking plates, the dust needs to consume power to climb upwards to pass through the gaps between the figure-eight dust-blocking plates, thereby further removing dust.

[0014] III. Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] The dust filter effectively filters the cool air entering the hard drive cage, preventing dust from entering the drive bay and accumulating on the working components, hindering heat dissipation and potentially causing overheating that could compromise data security. The removable dust filter allows for easy cleaning and maintenance, preventing dust buildup after prolonged heat exchange and ensuring efficient heat dissipation. The opening and closing mechanism allows the door to close after installation, facilitating hard drive operation. When the hard drive cage needs to be removed, the mechanism opens the door, allowing the cage to be pulled out and facilitating filter removal. The dust baffle further assists in dust removal.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combined with appendix Figure 1 and Figure 2A cloud storage card slot dustproof device includes a hard drive cage 1, a card slot that can cooperate with a hard drive is connected to the hard drive cage 1, a grid 2 is connected to the front side of the hard drive cage 1 near the card slot, and a door 3 is hinged to the front opening of the hard drive cage 1 by a torsion spring, and a dust filter screen 4 is provided on the door 3.

[0026] The hard drive rack is equipped with an exhaust fan and several arrays of hard drive cages 1. The arrangement of the grid 2, the door 3, and the dust filter 4 in the above structure facilitates the exhaust fan to filter the external cold air through the dust filter 4 on the door 3, and then introduce it into the hard drive rack through the grid 2 for heat dissipation when the hard drive is working.

[0027] Combined with appendix Figure 4 and Figure 5 The hard disk cage 1 is connected to an opening and closing assembly on one side of the door 3, which can open and close the door 3. The opening and closing assembly includes a locking block 10 connected to the door 3 away from the hinge. The locking block 10 has a right-angled triangular structure. The hard disk cage 1 is connected to a locking assembly that can be positioned with the door 3 in a locked state and an unlocking assembly that can unlock the locking assembly. The locking assembly includes a drive cavity 11 connected to the hard disk cage 1. A locking tongue 12 is slidably connected in the drive cavity 11. One end of the locking tongue 12 cooperates with the locking block 10 for limitation. A second spring 13 is connected between the other end of the locking tongue 12 and the drive cavity 11.

[0028] The locking block 10 and locking components in the above structure facilitate the closing of the compartment door 3, allowing cold air to pass through the dust filter 4 on the compartment door 3 before being introduced, preventing dust from entering and causing poor heat dissipation of various components, which could affect data security.

[0029] Combined with appendix Figure 4 and Figure 5 The unlocking component includes a pressure groove 14 connected to the front side of the hard disk cage 1. A pressure plate 15 is slidably connected in the pressure groove 14. A plurality of third springs 17 are connected between the pressure plate 15 and the pressure groove 14. A driving block 16 is connected to the pressure plate 15. The driving block 16 is a right-angled triangle structure or a right-angled trapezoidal structure. A U-shaped plate 18 is connected to the locking tongue 12. The other end of the driving block 16 extends into the driving cavity 11 and abuts against one end of the U-shaped plate 18 on the inclined surface. A roller groove is connected to one end of the U-shaped plate 18 that abuts against the inclined surface of the driving block 16. A roller 19 is rotatably connected in the roller groove. The roller 19 abuts against the inclined surface of the driving block 16 circumferentially.

[0030] The unlocking component in the above structure facilitates the opening of the compartment door. After the compartment door 3 is opened, the hard drive cage 1 can be pulled out of the hard drive rack through the compartment door 3. It also makes it easy to remove the dust filter 4 for cleaning.

[0031] Combined with appendix Figure 2The grid 2, the door 3, and the hard disk cage 1 enclose a dustproof chamber. Several dust-blocking components that can block dust are connected inside the dustproof chamber. The dust-blocking components include several dust-blocking units arrayed and connected inside the dustproof chamber. The dust-blocking unit is a figure-eight dust-blocking plate 20 that runs through the dustproof chamber. The bottom of the figure-eight dust-blocking plate 20 is connected to the dustproof chamber, and the top of the figure-eight dust-blocking plate 20 is connected to the dustproof chamber.

[0032] The dust-blocking components in the above structure help reduce the force of dust, thereby further assisting in dust removal.

[0033] Example 2

[0034] Based on Example 1, combined with Appendix Figure 2 and Figure 3 The door 3 is detachably connected to a dust filter 4, and the dust filter 4 is circumferentially connected to a support frame 5. The door 3 is connected to a through hole 6, and a limiting ring plate is connected to the side of the door 3 near the dust isolation chamber via the through hole 6. The through hole 6 cooperates with the support frame 5, and the support frame 5 is circumferentially connected to a limiting groove 7. Several grooves 9 are circumferentially connected to the through hole 6. A limiting block 8 is connected to the groove 9 by a first spring. The limiting block 8 is a spherical structure or a triangular structure, and the free end of the limiting block 8 cooperates with the limiting groove 7 for limiting.

[0035] The detachable and detachable design of the dust filter 4 in the above structure facilitates the disassembly and installation of the dust filter 4, thereby facilitating its maintenance and improving heat dissipation efficiency.

[0036] The specific usage method is as follows:

[0037] The opening and closing mechanism ensures that after the hard drive cage 1 is installed, the door 3 closes. When the door 3 rotates to close around the hinge, the locking block 10 drives the locking tongue 12 to slide into the driving cavity 11 until the locking block 10 and the locking tongue 12 are no longer in contact. At this point, the locking block 10 and the locking tongue 12 cooperate to limit the closing of the door 3, facilitating the operation of the hard drive. When it is necessary to remove the hard drive cage 1, the opening and closing mechanism drives the door 3 to open. By pressing the pressure plate 15, the third spring 17 is compressed and stored, pressing... Plate 15 drives drive block 16 to extend into drive cavity 11. The inclined surface on drive block 16 drives U-shaped plate 18 to drive lock tongue 12 to slide into drive cavity 11. Roller 19 circumferentially abuts against the inclined surface of drive block 16 to reduce friction and facilitate drive block 16 to drive U-shaped plate 18. At this time, second spring 13 is compressed and stored until lock tongue 12 no longer limits lock block 10. At this time, compartment door 3 is opened, and hard disk cage 1 is pulled out through compartment door 3. It also facilitates the disassembly of filter screen.

[0038] The dust filter 4 facilitates the filtration of cold air entering the hard drive cage 1, preventing dust from entering the hard drive rack and accumulating on the working parts, which would hinder heat dissipation and potentially affect data security due to overheating. The detachable design of the dust filter 4 allows for easy disassembly, cleaning, and maintenance, preventing dust accumulation on the surface of the dust filter 4 after prolonged heat exchange, which would affect heat dissipation efficiency. By engaging the support frame 5 with the dust filter 4 and the through hole 6 until the support frame 5 abuts against the limiting ring plate, the limiting block 8 slides out of the groove 9 under the elastic force of the first spring and engages with the limiting groove 7 at its end to install the dust filter 4. If the dust filter 4 needs to be removed, the door 3 needs to be opened first, and then the dust filter 4 is pushed open from the inside of the door 3 outwards, so that the support frame 5 drives the limiting block 8 to slide into the groove 9 under force. At this time, the first spring is compressed and stored, and the dust filter 4 can be removed.

[0039] The dust-blocking components facilitate further dust removal. The bottom of the bottom figure-eight dust-blocking plate 20 is connected to the dust-isolation chamber, and the top of the top figure-eight dust-blocking plate 20 is connected to the dust-isolation chamber. Some dust is introduced into the dust-isolation chamber through the dust-isolation net. Due to the setting of the figure-eight dust-blocking plates 20, the dust needs to consume power to climb upwards to pass through the gaps between the figure-eight dust-blocking plates 20, thereby further removing dust.
