Description

Technical Field

[0001] This utility model relates to a gasket for fixing a mechanical hard drive to a hard drive cage, specifically an alloy gasket for mechanical hard drives. Background Technology

[0002] Alloy washers for hard drives are primarily used to isolate the hard drive from its cage (or other hard drive mounting structures), ensuring a certain distance between them and preventing contact that could damage the hard drive. These alloy washers are typically made of alloy materials with high strength and corrosion resistance, capable of withstanding the high temperatures and pressures inside the hard drive.

[0003] Existing hard drive washers are usually just a ring-shaped piece of rubber (or silicone). The washer contacts the hard drive cage, and screws are driven through the cage and washer into the screw holes on the hard drive to secure it. However, because the washer is not specially designed or treated, it has poor cushioning effect when the hard drive vibrates. Furthermore, due to improper screw installation, it is easy for the washer to become misaligned, causing the hard drive to come into direct contact with the cage during vibration, which can lead to damage due to resonance. Utility Model Content

[0004] The purpose of this utility model is to provide an alloy gasket for mechanical hard drives. By setting an inner buffer structure and an outer buffer structure at both ends of the alloy part, the resonance generated between the mechanical hard drive and the hard drive cage during operation is greatly reduced, and the noise can also be reduced. This is beneficial to protecting the mechanical hard drive and reducing the probability of the mechanical hard drive being damaged by vibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an alloy gasket for a mechanical hard drive, comprising an alloy component, with an inner buffer structure and an outer buffer structure respectively provided at both ends of the alloy component, and a positioning nut provided on the outer buffer structure. The alloy component includes a retaining ring, and an installation groove is provided at the end of the retaining ring where the inner buffer structure is located. The inner buffer structure includes an air bladder, which includes an inner bladder body and an outer protruding bladder body fixed to the inner bladder body, and an air chamber is provided inside the air bladder. The outer buffer structure includes a positioning post, with an external thread provided on the outer circle of the positioning post. The positioning nut includes a cap body, which is a cavity structure with openings at both ends and a hollow interior, and an internal thread is tapped inside the cavity of the cap body. The internal thread and the external thread cooperate to allow the outer buffer structure and the positioning nut to be installed together. Through the cooperation of the outer buffer structure and the positioning nut, the outer buffer structure and the alloy component can be completely fixed to the hard drive cage.

[0006] Preferably, the fixing ring is provided with screw holes that extend through both sides, and the positioning post is provided with mounting holes that extend through both sides, with the screw holes communicating with the mounting holes.

[0007] Preferably, the inner bladder is located within the mounting groove, and the outer bulge protrudes from the surface of the fixing ring.

[0008] Preferably, the interior of the air chamber is hollow, and the air pressure inside the air chamber is greater than one standard atmosphere.

[0009] Preferably, the inner buffer structure further includes two sets of fixing blocks, both sets of fixing blocks are fixedly connected to the inner bladder body, and both sets of fixing blocks are fixed to the fixing ring. The two sets of fixing blocks are respectively set on the inner and outer sides of the airbag, each set of fixing blocks has multiple blocks, and the multiple fixing blocks are distributed in the circumferential direction of the inner bladder body.

[0010] Preferably, the positioning post is fixed to one end of the fixing ring near the cap body, and the positioning post and the fixing ring are designed to be coaxial.

[0011] Preferably, the outer cushioning structure also includes a rubber ring, which is fixed to one end of the fixing ring near the cap body.

[0012] Preferably, a hard disk cage fixing groove is provided between the fixing ring and the cap body, and the hard disk cage fixing groove is designed in a ring shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention incorporates an inner buffer structure and an outer buffer structure at both ends of the alloy component. The inner buffer structure directly contacts the hard drive to cushion it, reducing the impact of hard drive vibration on the alloy component. The outer buffer structure contacts the hard drive cage (or hard drive bracket), firmly securing the alloy component and the inner buffer structure. This further reduces the impact of vibration on the hard drive cage, significantly reducing the resonance between the hard drive and the cage during operation, thus lowering noise levels. This design helps protect the hard drive and reduces the probability of damage caused by vibration. Attached Figure Description

[0024] Please see Figure 1One embodiment of this utility model is an alloy gasket for a mechanical hard disk, comprising an alloy part 1, with an inner buffer structure 2 provided at one end of the alloy part 1.

[0025] Please see Figure 2 An outer buffer structure 3 is provided at the other end of the alloy part 1, and a positioning nut 4 is provided on the outer buffer structure 3.

[0026] Please see Figure 3 Alloy component 1 includes a retaining ring 11. A mounting groove 12 is provided at the end of the retaining ring 11 where the inner buffer structure 2 is located. The retaining ring 11 has screw holes 13 penetrating both sides. The inner buffer structure 2 includes an airbag 21, which includes an inner bladder 211 and an outer protruding bladder 212 fixed to the inner bladder 211. The inner bladder 211 is located within the mounting groove 12, and the outer protruding bladder 212 protrudes from the surface of the retaining ring 11. During the installation of the hard drive, the outer protruding bladder 212 can easily contact and buffer the hard drive. When the outer protruding bladder 212 contacts the hard drive... After the mechanical hard drive comes into contact with and is subjected to pressure, both the outer bulge 212 and the inner bulge 211 contract towards the mounting groove 12. At this time, the space within the mounting groove 12 can accommodate the compressed air bladder 21. Simultaneously, the air bladder 21 is gradually compressed during the compression process, thus utilizing its own structural characteristics to provide good cushioning for the mechanical hard drive. In the default state, the outer bulge 212 protrudes from the surface of the fixing ring 11. Furthermore, the air bladder 21 contains an air chamber 213, which is hollow inside, and the air pressure within the air chamber 213 is greater than one standard atmosphere. The pressure is 1.02 to 1.05 times that of a standard atmosphere. Furthermore, the inner buffer structure 2 includes two sets of fixing blocks 22, both of which are fixedly connected to the inner bladder 211 and fixed to the fixing ring 11. The two sets of fixing blocks 22 are respectively located on the inner and outer sides of the airbag 21. Each set of fixing blocks 22 has multiple blocks, distributed circumferentially around the inner bladder 211. The outer buffer structure 3 includes a positioning post 31, which is fixed to the end of the fixing ring 11 near the positioning nut 4. The positioning post 31 is connected to the fixing ring 11... The coaxial design includes mounting holes 32 on both sides of the positioning post 31. Screw holes 13 communicate with the mounting holes 32, allowing screws for fixing the hard drive to pass through the mounting holes 32, the hard drive cage, and the screw holes 13 in sequence, ultimately driving into the hard drive and fixing it to the hard drive cage. The outer buffer structure 3 also includes a rubber ring 34, which is fixed to the end of the fixing ring 11 near the positioning nut 4. In this embodiment, both the airbag 21 and the rubber ring 34 are made of rubber or silicone. The rubber ring 34 is used to contact the hard drive cage and provide buffering between the fixing ring 11 and the hard drive cage.

[0027] Please see Figure 4The outer circle of the positioning post 31 is provided with an external thread 33. The positioning nut 4 includes a nut body 41, which is a cavity structure with openings at both ends and a hollow interior. The cavity of the nut body 41 is tapped with an internal thread 42. The internal thread 42 and the external thread 33 cooperate to allow the external buffer structure 3 and the positioning nut 4 to be installed together. Through the cooperation of the external buffer structure 3 and the positioning nut 4, the external buffer structure 3 and the alloy part 1 can be completely fixed on the hard disk cage.

[0028] Please see Figure 5 A hard disk cage fixing groove 5 is provided between the fixing ring 11 and the cap body 41. The hard disk cage fixing groove 5 is annular in design. The space inside the hard disk cage fixing groove 5 is used for the hard disk cage of the mechanical hard disk to pass through, so that the fixing ring 11 and the cap body 41 cooperate. The fixing ring 11 and the cap body 41 are respectively tightly fitted to the inner and outer sides of the hard disk cage, and the positioning post 31 is completely fixed on the hard disk cage, thereby keeping the alloy part 1 and the inner buffer structure 2 structurally stable.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
