Description

Technical Field

[0001] The present invention relates to the technical field of hard disk brackets, and in particular to an expandable hard disk bracket with a vibration reduction function and a method thereof. Background Art

[0002] An industrial computer is a computer device specially used in industrial automation control systems. It plays an important role in the industrial production process. It usually needs to run for a long time and have the ability to resist interference and vibration. The storage hard disk is one of the important components of an industrial computer.

[0003] The mainstream hard drives on the market are roughly divided into 3.5-inch and 2.5-inch drives. The length and width of 3.5-inch drives are 174 mm and 101 mm respectively, and the thickness is about 18 mm. The length and width of 2.5-inch drives are 101.85 mm and 69.85 mm respectively, and the thickness is about 15 mm. The interfaces of 3.5-inch and 2.5-inch drives are roughly the same distance from the single corner of their hard drive housings.

[0004] Chinese patent CN116483177B discloses a combined hard disk bracket, which realizes the increase of the number of brackets in the chassis by stacking or reducing a plurality of accommodating parts, so as to accommodate more hard disks and avoid occupying the chassis space. However, the hard disk bracket still has the following problems:

[0005] 1. The hard disk bracket can only accommodate hard disks of a specific size. If the user has two types of hard disks at the same time, an additional expansion bracket needs to be installed to achieve mixed use of 3.5-inch and 2.5-inch disks. Not only does it require more operations, but when the bracket is loaded with a 3.5-inch disk, the user needs to remove the expansion bracket and store it separately, which is inconvenient to use.

[0006] 2. The user needs to remove the screws of the first extension part to realize the operation of taking and placing the hard disk. Large industrial computers are often equipped with many hard disks to meet storage needs. If the hard disk bracket is used to take and place multiple hard disks, the user's operation is cumbersome and inconvenient.

[0007] Based on this, the present invention designs an expandable hard disk bracket with vibration reduction function and a method thereof to solve the above-mentioned problem. Summary of the invention

[0008] In view of the above-mentioned shortcomings of the prior art, the present invention provides an expandable hard disk bracket with a vibration reduction function and a method thereof.

[0018] Furthermore, the inner bracket is provided with an upper screw hole A and an upper screw hole B, and the movable plate is provided with a lower screw hole connected with the upper screw hole A and the upper screw hole B. When the upper screw hole A and the lower screw hole are aligned, the single angle positioning A and the single angle positioning B are used to clamp a large-size hard disk, and when the upper screw hole B and the lower screw hole are aligned, the single angle positioning A and the single angle positioning B are used to clamp a small-size hard disk.

[0019] Furthermore, the synchronous locking mechanism includes a sliding sleeve, a sliding rod, a through groove and a movable pin. The sliding sleeve is fixedly connected to the side plate, and the side wall of the sliding rod is slidingly connected to the inner wall of the sliding sleeve; the sliding sleeve is provided with a through groove, and the locking block is provided with a movable groove.

[0062] In the present invention, the locking block 400 is moved to rotate until the locking block 400 no longer blocks the movement of the inner bracket 200. During the rotation of the locking block 400, the movable pin 504 slides in the movable groove 401 and the through groove 503, and the movable pin 504 drives the slide bar 502 to move vertically, and finally the movable pin 504 moves from one end of the through groove 503 and the movable groove 401 to the other end thereof; the user can pull the inner bracket 200 out of the storage compartment 100, place a hard disk on the inner bracket 200 and then insert the inner bracket 200 back into the storage compartment 100, and the user releases the locking block 400, and the locking spring 50 5 and the fixing ring 506 drive the slide bar 502 to reset, and the slide bar 502 drives the locking block 400 to reset through the movable pin 504, thereby achieving the fixing effect of the inner bracket 200; at the same time, if multiple storage bins 100 are combined into a whole, it is only necessary to move the locking block 400 of the top storage bin 100 to drive its slide bar 502 to move, and the slide bar 502 will be inserted into the lower sliding sleeve 501 to drive the adjacent slide bar 502 to move, so that the locking blocks 400 of all the storage bins 100 as a whole rotate synchronously, realizing the one-time unlocking and fixing operation of all the inner brackets 200, which is convenient for users to take and put hard disks.

The clamping wheel A203 drives the movable plate 304 to move under the limiting action of the dovetail block 305 and the dovetail groove 306. At the same time, under the action of the movable block 302 and the inclined groove 303, the clamping wheel B204 moves in the slide groove 301 toward the direction of the positioning block B202 until the upper screw hole B308 and the lower screw hole 309 are aligned and then fixed by screws. At this time, the clamping wheel A203 and the clamping wheel B204 both slide from one end of the slide groove 301 to the other end of the slide groove 301. The positioning block A201, the positioning block B202, the clamping wheel A203 and the clamping wheel B204 can fix the 2.5-inch hard disk;

The expandable hard disk bracket with vibration reduction function according to claim 4, characterized in that: The inner bracket (200) is provided with an upper screw hole A (307) and an upper screw hole B (308); the movable plate (304) is provided with a lower screw hole (309) connected to the upper screw hole A (307) and the upper screw hole B (308); when the upper screw hole A (307) and the lower screw hole (309) are aligned, the single angle positioning A and the single angle positioning B are used to clamp a large-sized hard disk; when the upper screw hole B (308) and the lower screw hole (309) are aligned, the single angle positioning A and the single angle positioning B are used to clamp a small-sized hard disk.

6. A method for an expandable hard disk support with vibration reduction function as claimed in claim 5, characterized in that: The following steps are involved: Step 1: The user fixes the uppermost storage compartment (100) to the chassis, and combines a plurality of storage compartments (100) into a whole through the plug-in slots (111) and the plug-in blocks (112), and the grooves (114) and the protrusions (113) are engaged to tightly combine adjacent storage compartments (100); Step 2: The user turns the locking block (400) to rotate it, and the locking block (400) drives the locking blocks (400) of all the receiving compartments (100) to rotate synchronously through the sliding rod (502), so that all the locking blocks (400) no longer block the movement of the inner bracket (200); after the inner bracket (200) is pulled out of the receiving compartment (100), a large-size hard disk is inserted into the inner bracket (200), and the hard disk is quickly clamped and fixed by the single-angle positioning A and the single-angle positioning B; Step 3: When mixing small-sized hard disks, remove the screws from the upper screw holes A (307), push the clamping wheel A (203) in the direction of the positioning block A (201), and the clamping wheel A (203) drives the movable plate (304) to move under the limiting action of the dovetail block (305) and the dovetail groove (306). At the same time, under the action of the movable block (302) and the inclined groove (303), the clamping wheel B (204) is moved in the slide groove (301). Move in the direction of the positioning block B (202) until the upper screw hole B (308) is aligned with the lower screw hole (309) and then fix it with screws. At this time, the clamping wheel A (203) and the clamping wheel B (204) slide from one end of the slide groove (301) to the other end of the slide groove (301). The positioning block A (201), the positioning block B (202), the clamping wheel A (203) and the clamping wheel B (204) can fix the small-sized hard disk; Step 4: The user releases the locking block (400), the locking spring (505) and the fixing ring (506) drive the slide bar (502) to reset, and the slide bar (502) drives the locking block (400) to reset through the movable pin (504), thereby achieving a fixing effect on the inner bracket (200), and the locking blocks (400) of all the receiving bins (100) rotate synchronously, fixing all the inner brackets (200).
