Abstract
Description
Technical Field
[0001] This utility model relates to the field of server hard drive rack installation technology, and more specifically, to a server hard drive rack anti-vibration locking device. Background Technology
[0002] Server hard drive enclosures are specialized devices used to secure, protect, and connect server hard drives, primarily installed inside the server chassis. Their core functions include housing the hard drives, providing thermal protection, supporting hot-swappable maintenance, and ensuring stable data transmission.
[0003] Existing server hard drive racks are installed by aligning the rack (if it is a separate component) with the bay slot, gently pushing it in until it is fully engaged, and then securing it with screws (if there are screw holes on both sides of the bay) to ensure the rack is stable and does not wobble. However, the disadvantage of using screws for securing the rack is that when the chassis vibrates, the screws can easily loosen, causing the rack to become unstable and potentially damaging the hard drives installed on it, thus affecting their lifespan. Therefore, we propose a server hard drive rack anti-vibration locking device to solve the above-mentioned problems. Utility Model Content
[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a server hard drive rack anti-vibration locking device. It uses a concentric locking structure design between the concave nut and the convex nut, and the wedge-shaped surface is deformed by the slotting action. During the tightening process of the convex nut, a larger normal force is generated, thereby improving the relaxation performance of the hard drive rack body in a vibration environment, thus preventing the hard drives installed on the hard drive rack body from being damaged by vibration.
[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.
[0006] A server hard drive rack anti-vibration locking device includes a hard drive rack body and mounting holes symmetrically opened at the bottom of the hard drive rack body, and screws are installed on the inner side of the mounting holes. A washer is mounted on the screw; A concave nut is provided above the washer to be screwed into the screw, and a wedge-shaped groove is provided at the top of the concave nut; A convex nut is provided above the concave nut and is screwed to the screw. The root of the convex nut is provided with a wedge-shaped surface that abuts against the wedge-shaped groove. The side of the convex nut is provided with a slot. Specifically, there are three slots, one of which passes through the convex nut, and the other two slots extend to the root of the wedge-shaped surface.
[0007] Furthermore, the lower surface of the pad is integrally formed with anti-slip teeth that fit tightly against the hard disk frame body, and multiple anti-slip teeth are provided in the radial position of the pad; The anti-slip teeth are provided with an inclined surface, and the orientation of the inclined surface is opposite to the orientation of the thread on the screw.
[0008] Furthermore, the top edge of the concave nut is integrally formed with a first protruding tooth, and multiple first protruding teeth are provided in the radial position of the concave nut.
[0009] Furthermore, the root of the wedge-shaped surface is provided with a flange integrally formed with the convex nut; The lower surface of the flange is fixedly connected to a second protruding tooth, and the second protruding tooth and the inclined surface on the first protruding tooth are arranged in opposite directions.
[0010] Furthermore, a rubber washer is installed between the concave nut and the convex nut.
[0011] Furthermore, the included angle between two adjacent slots corresponding to the central axis of the convex nut is 120°.
[0012] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) In this solution, after the mounting holes at the bottom of the hard drive rack body correspond to the mounting holes in the compartment, the screws pass through the mounting holes and the mounting holes in sequence. A washer is placed on the screw to increase the friction between it and the concave nut. Then, a convex nut is installed on the screw so that the wedge-shaped surface is embedded into the inside of the wedge groove. Through the concentric locking structure design between the concave nut and the convex nut, and the deformation of the wedge-shaped surface under the action of the slot, a greater normal force is generated during the tightening of the convex nut, thereby improving the relaxation performance of the hard drive rack body under vibration environment, thereby preventing the hard drive installed on the hard drive rack body from being damaged by vibration.
[0013] (2) In this solution, the first convex tooth and the second convex tooth engage with the rubber washer, and the inclined surfaces on the second convex tooth and the first convex tooth are set in opposite directions, which can effectively increase the friction between them and the rubber washer, thereby further preventing the loosening between the concave nut and the convex nut.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.
[0017] Example: Please see Figure 1-6 A server hard drive rack anti-vibration locking device includes a hard drive rack body 1 and mounting holes 2 symmetrically opened at the bottom of the hard drive rack body 1, with screws 3 installed on the inner side of the mounting holes 2. Screw 3 is fitted with washer 4; A concave nut 6 is provided above the washer 4 and is screwed to the screw 3. A wedge-shaped groove 7 is provided at the top of the concave nut 6. A convex nut 9 is provided above the concave nut 6 and is screwed to the screw 3. A wedge-shaped surface 10 is provided at the root of the convex nut 9 and abuts against the wedge-shaped groove 7. A slot 14 is provided on the side of the convex nut 9. Specifically, there are three slots 14, one of which passes through the convex nut 9, and the other two slots 14 extend to the root of the wedge-shaped surface 10. It should be noted that when using this server hard drive rack anti-vibration locking device, after the mounting hole 2 at the bottom of the hard drive rack body 1 corresponds to the mounting hole in the bay, the screw 3 passes through the mounting hole and the mounting hole 2 in sequence. A washer 4 is placed on the screw 3 to increase the friction between it and the concave nut 6. Then, the convex nut 9 is installed on the screw 3 so that the wedge-shaped surface 10 is embedded into the inside of the wedge-shaped groove 7. Through the concentric locking structure design between the concave nut 6 and the convex nut 9, and under the action of the slot 14, the wedge-shaped surface 10 is deformed. During the tightening process of the convex nut 9, a larger normal force is generated, thereby improving the relaxation performance of the hard drive rack body 1 in a vibration environment, thus preventing the hard drive installed on the hard drive rack body 1 from being damaged by vibration.
[0018] like Figure 5 As shown, the lower surface of the pad 4 is integrally formed with anti-slip teeth 5 that fit tightly against the hard disk frame body 1, and multiple anti-slip teeth 5 are provided in the radial position of the pad 4. The anti-slip teeth 5 are provided with an inclined surface, and the orientation of the inclined surface is opposite to the orientation of the thread on the screw 3. It should be noted that by utilizing the anti-slip teeth 5 at the bottom of the pad 4, the friction between it and the hard drive frame body 1 can be effectively increased. Furthermore, the orientation of the inclined surface on the anti-slip teeth 5 is opposite to the orientation of the thread on the screw 3, which can further improve the relaxation effect of the pad 4.
[0019] like Figure 4 As shown, the top edge of the concave nut 6 is integrally formed with a first protruding tooth 8, and multiple first protruding teeth 8 are provided in the radial position of the concave nut 6. The root of the wedge-shaped surface 10 is provided with a flange 11 integrally formed with the convex nut 9. The lower surface of the flange 11 is fixedly connected with a second protruding tooth 12, and the second protruding tooth 12 is arranged in opposite directions to the inclined surface on the first protruding tooth 8. A rubber washer 13 is installed between the concave nut 6 and the convex nut 9. It should be noted that by engaging the first protruding tooth 8 and the second protruding tooth 12 with the rubber washer 13, and by setting the inclined surfaces of the second protruding tooth 12 and the first protruding tooth 8 in opposite directions, the friction between them and the rubber washer 13 can be effectively increased, thereby further preventing the loosening between the concave nut 6 and the convex nut 9.
[0020] like Figure 6 As shown, the included angle between the two adjacent slots 14 and the corresponding central axis of the convex nut 9 is 120°; It should be noted that, through the concentric locking structure design between the concave nut 6 and the convex nut 9, and the deformation of the wedge surface 10 under the action of the slot 14, a greater normal force is generated during the tightening process of the convex nut 9, thereby improving the relaxation performance of the hard disk rack body 1 under vibration environment.
[0021] In use: After the mounting hole 2 at the bottom of the hard drive rack body 1 corresponds to the mounting hole in the compartment, the screw 3 passes through the mounting hole and the mounting hole 2 in sequence. A washer 4 is placed on the screw 3 to increase the friction between it and the concave nut 6. Then, the convex nut 9 is installed on the screw 3 so that the wedge surface 10 is embedded into the inside of the wedge groove 7. Through the concentric locking structure design between the concave nut 6 and the convex nut 9, and under the action of the slot 14, the wedge surface 10 is deformed. During the tightening process of the convex nut 9, a larger normal force is generated, thereby improving the relaxation performance of the hard drive rack body 1 in a vibration environment, thus preventing the hard drive installed on the hard drive rack body 1 from being damaged by vibration.
[0022] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
