Description

Technical Field

[0001] This invention relates to the field of computer chassis technology, specifically to a computer chassis for hard disk servers. Background Technology

[0002] Server hard drives, as the name suggests, are hard drives used on servers. If the server is the core of network data, then the server hard drive is the data warehouse of this core, where all software and user data are stored. Since the data stored on the server's hard drive is the user's most valuable information, the reliability of the hard drive is extremely important.

[0003] To facilitate server management, computer cases are typically provided to protect the servers. However, existing computer cases are usually installed using a large number of screws. Since the screws are small, they are easily lost after disassembly and need to be replaced, resulting in a lot of time wasted on disassembly and installation. Therefore, further improvements can be made. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a computer chassis for hard disk servers, which has the advantages of convenient and quick disassembly and installation, saving time and effort, and solving the problems mentioned above.

[0006] (II) Technical Solution

[0007] To address the aforementioned problems, the present invention provides the following technical solution: a computer chassis for a hard disk server, comprising a base, a front frame, and a rear frame. The bottom end of the front frame is inserted into the top of the front side of the base, and the rear frame is disposed on the top of the back side of the base. A top cover is detachably installed on the top of the rear frame, and a retractable and expandable limiting component is provided on the top of the rear frame. A filter screen is provided on the front side of the front frame, and a side plate is provided between the front frame and the rear frame.

[0008] A fixing plate is fixedly installed on the top side of the base. The fixing plate has a slot inside, a snap-fit ​​groove inside the front end, and a threaded hole at the rear end.

[0009] Furthermore, a card plate is fixedly installed at the bottom of the front frame, and first sliding grooves are opened inside the left and right sides of the front frame. The card plate is inserted into the inside of the card slot. By inserting the card plate into the card slot, the front frame is installed. The installation method is convenient and quick.

[0010] Furthermore, a second sliding groove is provided on one side of the back frame relative to the front frame, and a back plate is provided between the two sets of second sliding grooves. A third sliding groove is provided on the opposite side of each set of back frames. The back plate is slidably connected inside the third sliding groove. A threaded rod is fixedly installed at the bottom end of the back frame, and the threaded rod is threadedly connected inside the threaded hole. The threaded rod is threadedly connected inside the threaded hole, which serves to install the two sets of back frames. Because it is a threaded connection, disassembly and installation are very convenient.

[0011] Furthermore, the two sides of the side plate are slidably connected to the inside of the first slide groove and the second slide groove, respectively, and the bottom end of the side plate is inserted into the inside of the slot. The first slide groove, the second slide groove and the slot serve to install the side plate.

[0012] Furthermore, each of the four corners of the top cover has a locking hole, and the diameter of the locking hole is larger than the diameter of the limiting component after it is contracted, while the diameter of the locking hole is smaller than the diameter of the limiting component in its initial state. The limiting component passes through the top cover to play a positioning and limiting role for the top cover.

[0013] Furthermore, the limiting component includes a vertical pole, which is fixedly installed at the top of the front frame. A rotating plate is rotatably connected to the top outer side of the vertical pole. A return spring is sleeved on the bottom outer side of the rotating plate. A ring is fixedly installed at the top of the return spring. Connecting rods are rotatably connected to the outer sides of the ring. Support plates are fixedly installed on the inner sidewalls of the rotating plate corresponding to the ring.

[0014] Furthermore, four sets of rotating plates are arranged in an array around the outer side of the upright. In the initial state, the four sets of rotating plates pass through the locking holes and are locked on the top side of the top cover. After the rotating plates shrink and deform, they will lock the top cover after passing through the locking holes, thus playing a role in limiting the installation of the top cover.

[0015] Furthermore, the bottom end of the reset spring is fixedly installed at the top of the front frame, and the ring is slidably connected to the outside of the upright. As the ring slides down along the upright, it will compress the reset spring, thereby enabling the reset spring to return the ring to its original position.

[0016] Furthermore, the connecting rods are arranged in four sets around the ring, and the top of each set of the rings is rotatably connected to the support plate. When the rotating plate is pressed, the bottom end retracts inward, which will drive the connecting rods to shift downward through the support plate, thereby causing the ring to press down on the return spring.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a computer chassis for a hard disk server, which has the following advantages:

[0019] This computer chassis for hard drive servers uses a latch plate that inserts into a latching slot to mount the front frame. A threaded rod connects to a threaded hole to mount the rear frame. First and second sliding grooves allow the side panels to slide downwards and snap into the latching slots. The second sliding groove allows the side panels to slide between the two rear frames. Finally, a rotating plate retracts through a latching hole, and a return spring drives a ring upwards to reset the chassis. This, in turn, causes the support plate to return to its initial state via a connecting rod, resulting in the rotating plate locking onto the outside of the latching hole. This completes the chassis assembly quickly and easily. Disassembly is simple: press the rotating plate to retract its outer diameter, remove the top cover, and then pull out the side and rear panels. Since no screws are used, disassembly and assembly are very convenient, saving time and effort. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 A computer chassis for a hard disk server includes a base 1, a front frame 2, and a rear frame 3. The bottom end of the front frame 2 is inserted into the top of the front side of the base 1. The rear frame 3 is disposed on the top of the back side of the base 1. A top cover 4 is detachably installed on the top of the rear frame 3. A retractable and expandable limiting component 5 is provided on the top of the rear frame 3. A filter 6 is provided on the front side of the front frame 2. A side plate 7 is provided between the front frame 2 and the rear frame 3.

[0032] Please see Figure 2-3 and Figure 7 A fixing plate 11 is fixedly installed on the top side of the base 1. The fixing plate 11 has a slot 12 inside, a snap-fit ​​groove 13 inside the front end of the fixing plate 11, and a threaded hole 14 inside the rear end of the fixing plate 11.

[0033] Please see Figure 3-4 A card plate 21 is fixedly installed at the bottom of the front frame 2. First sliding grooves 22 are opened inside the left and right sides of the front frame 2, and the card plate 21 is inserted into the inside of the card slot 13. The card plate 21 is inserted into the inside of the card slot 13 to install the front frame 2. The installation method is convenient and quick.

[0034] Please see Figure 2-3 and Figure 5-7 The back frame 3 has a second sliding groove 31 on the side opposite to the front frame 2. A back plate 32 is provided between the two sets of second sliding grooves 31. A third sliding groove 33 is provided on the opposite side of each set of back frames 3. The back plate 32 is slidably connected inside the third sliding groove 33. A threaded rod 34 is fixedly installed at the bottom of the back frame 3, and the threaded rod 34 is threadedly connected inside the threaded hole 14. The threaded rod 34 is threadedly connected inside the threaded hole 14, which serves to install the two sets of back frames 3. Because it is a threaded connection, disassembly and installation are very convenient.

[0035] Please see Figure 1-2 The two sides of the side plate 7 are slidably connected to the inside of the first slide groove 22 and the second slide groove 31 respectively. The bottom end of the side plate 7 is inserted into the inside of the slot 12. The first slide groove 22, the second slide groove 31 and the slot 12 serve to install the side plate 7.

[0036] Please see Figure 8 Each of the four corners of the top cover 4 has a locking hole 41, and the diameter of the locking hole 41 is larger than the diameter of the limiting component 5 after it is contracted, while the diameter of the locking hole 41 is smaller than the diameter of the limiting component 5 in its initial state. The limiting component 5 passes through the top cover 4 to play a positioning and limiting role for the top cover 4.

[0037] Please see Figure 9 The limiting component 5 includes a pole 51, which is fixedly installed on the top of the front frame 2. A rotating plate 52 is rotatably connected to the top outer side of the pole 51. Four sets of rotating plates 52 are arranged around the outer side of the pole 51. In the initial state, the four sets of rotating plates 52 pass through the locking hole 41 and are locked on the top side of the top cover 4. After the rotating plates 52 are deformed by shrinking, they will lock the top cover 4 after passing through the locking hole 41, thus playing a role in limiting the installation of the top cover 4.

[0038] Please see Figure 9 A return spring 53 is sleeved on the bottom outer side of the rotating plate 52. The bottom end of the return spring 53 is fixedly installed on the top end of the front frame 2. A ring 54 is fixedly installed on the top end of the return spring 53. The ring 54 is slidably connected to the outside of the upright 51. The ring 54 will squeeze and compress the return spring 53 by sliding down along the upright 51, so that the return spring 53 can play the role of resetting the ring 54 upward.

[0039] Please see Figure 9 Connecting rods 55 are rotatably connected to the outer sides of the ring 54. Four sets of connecting rods 55 are arranged in an array around the ring 54. Support plates 56 are fixedly installed on the inner sidewalls of the rotating plate 52 corresponding to the ring 54. The top of each ring 54 is rotatably connected to the support plate 56. When the rotating plate 52 is pressed, the bottom end retracts inward, which will drive the connecting rods 55 to shift downward through the support plate 56, thereby causing the ring 54 to press down and squeeze the return spring 53.

[0040] Working principle: Please refer to Figure 1-9 When assembling the computer case, first insert the clip plate 21 into the slot 13 to install the front frame 2 on the top front end of the base 1. Then, align the threaded rod 34 with the threaded hole 14 and rotate it clockwise to install the back frame 3 on the top rear end of the base 1. Then, slide the side plate 7 down along the first slide groove 22 and the second slide groove 31 until it is inserted into the slot 12. Then slide the back plate 32 down along the second slide groove 31. At this point, the installation of the four side walls of the case is completed.

[0041] Finally, align the four corner holes 41 of the top cover 4 with the limiting component 5 and press down. This will compress the four sets of rotating plates 52, causing the bottom of the rotating plates 52 to retract inward. This will cause the connecting rod 55 to shift downward through the support plate 56, which in turn will cause the ring 54 to press down along the upright 51 to squeeze the return spring 53. At this time, the outer diameter of the rotating plate 52 shrinks to be smaller than the inner diameter of the hole 41, so it can pass through the hole 41. After the rotating plate 52 passes through the hole 41, the return spring 53 will cause the ring 54 to return upward. Therefore, the connecting rod 55 will cause the support plate 56 to return to its initial state. At this time, the outer diameter of the rotating plate 52 is larger than the inner diameter of the hole 41, so it will be locked on the outside of the hole 41, thus completing the installation of the top cover 4 and completing the assembly of the chassis. This is very convenient and quick.

[0042] When disassembling the chassis, simply press the rotating plate 52 to shrink its outer diameter, then the top cover 4 can be removed. After that, the side panel 7 and back panel 32 can be pulled out upwards, fully exposing the internal hard drive server. This makes it convenient for maintenance personnel to repair the server without complicated steps, saving time and effort.

[0043] In summary, this computer chassis for a hard disk server uses a card plate 21 inserted into the slot 13 to mount the front frame 2, and a threaded rod 34 threaded into the threaded hole 14 to mount the rear frame 3. The first and second sliding grooves 22 and 31 facilitate the downward sliding of the side panel 7 into the slot 12. The second sliding groove 31 allows the side panel 7 to slide along the back panel 32 between the two rear frames 3. Finally, the rotating plate 52 retracts through the slot 41, and the chassis is then secured by a return spring 5. 3 drives the ring 54 to reset upwards, which in turn drives the support plate 56 to return to its initial state through the connecting rod 55. Therefore, the rotating plate 52 will be stuck on the outside of the locking hole 41. At this time, the assembly of the chassis is completed, which is very convenient and quick. When the chassis needs to be disassembled, simply press the rotating plate 52 to shrink its outer diameter, and then the top cover 4 can be taken out. After that, the side plate 7 and the back plate 32 can be pulled out upwards. Since it is not installed with screws, disassembly and installation are very convenient, thus achieving convenient, quick and easy disassembly and installation, saving time and effort.
