Description

Technical Field

[0001] This invention relates to the field of data transmission technology, specifically to a data transmission device for system data backup and recovery and its usage method. Background Technology

[0002] In system data backup and recovery, commonly used data transmission devices mainly include the following types: providing centralized storage space through a network and supporting access from multiple devices, or connecting storage devices to servers through a high-performance dedicated network. During transmission, the devices need to be connected to routers via fiber optic cables.

[0003] For example, the patent publication number CN223899223U published on the China Patent Network is titled: "A Network Security Data Transmission Device Includes a User Terminal, a Controller, and a Cable." The user terminal has a controller internally, and a cable is mounted on the top of the controller. The device further includes a movable component slidably disposed on the inner wall of the user terminal and a clamping component slidably disposed on the front surface of the movable component. Through the coordinated operation of the slider, insert rod, and pull ring, the support block is moved left and right. Through the coordinated operation of the limiting rod and push rod, the support block is limited. Through the coordinated operation of the pressure plate, pressure rod, and pressure block, the push block is moved left and right, thereby clamping the cable. The coordinated operation of these components allows for convenient and quick cable routing, enhancing the aesthetics of the user terminal and facilitating future maintenance.

[0004] However, existing transmission equipment mainly consists of a large number of hard drives used for storage. Each hard drive needs to be connected to an external switch via fiber optic cable. When maintaining a single hard drive or replacing a faulty hard drive, the corresponding fiber optic cable must be manually plugged and unplugged one by one. In systems with hundreds or thousands of hard drives, this process is extremely tedious and slow, significantly extending the maintenance window. At the same time, a large number of fibers converge at the back of the cabinet, forming a dense cable bundle, which not only affects heat dissipation but also makes it difficult for technicians to access and operate the target cables, further reducing efficiency. Finally, during reinstallation, technicians must rely on potentially incomplete or outdated paper labels, forms, or memory to determine which precise port each fiber optic cable should be plugged back into on the switch, a process highly prone to errors.

[0005] Therefore, it is necessary to redesign and modify the data transmission equipment and its usage methods for system data backup and recovery. Summary of the Invention

[0006] To address the problems mentioned in the background section, the present invention aims to provide a data transmission device and its usage method for system data backup and recovery. This device offers the advantage of facilitating the simultaneous and accurate connection of numerous optical fibers, solving the problem that existing transmission equipment primarily consists of numerous hard drives used for storage. Each hard drive requires connection to an external switch via optical fiber, necessitating manual unplugging and plugging of the corresponding optical fiber cables when maintaining a single hard drive or replacing a faulty one. In systems with hundreds or thousands of hard drives, this process is extremely tedious and slow, significantly extending maintenance windows. Furthermore, the large number of optical fibers converging at the rear of the cabinet forms dense cable bundles, affecting heat dissipation and making it difficult for technicians to access and operate the target cables, further reducing efficiency. Finally, during reinstallation, technicians must rely on potentially incomplete or outdated paper labels, forms, or memory to determine the precise port on the switch where each optical fiber should be plugged back, a process highly prone to errors.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a data transmission device for system data backup and recovery and a method for using the same, comprising a body; Several hard disk assemblies are inserted into the front of the machine body. The front of each hard disk assembly is electrically connected to a data interface. Fiber optic connectors are inserted into the inside of the data interface. A connection frame is provided on the front of the machine body. The fiber optic connectors are inserted into the connection frame. A positioning structure is provided at the bottom of the connection frame. The positioning structure can synchronously position and connect multiple fiber optic connectors to the connection frame. A release structure is provided at the top of the connection frame. The release structure can synchronously release the latches on the surfaces of multiple fiber optic connectors.

[0008] As a preferred embodiment of the present invention, a crossbeam is fixedly connected to the bottom of the connecting frame, and the two ends of the crossbeam extend to the two sides of the front of the machine body respectively. Movable blocks are fixedly connected to the left and right sides of the machine body, and sliding rods are fixedly connected to both ends of the crossbeam. The end of the sliding rod away from the crossbeam passes through the movable block and is slidably connected to the movable block.

[0009] As a preferred embodiment of the present invention, the positioning structure includes connecting blocks fixedly connected to both sides of the bottom of the crossbeam. The inner side of the connecting blocks is movably connected to a shaft via a bearing. The shaft is located at the bottom of the crossbeam. Several pressure plates are fixedly connected to the surface of the shaft. The pressure plates are located on both sides of the fiber optic connector. The side of the pressure plate away from the shaft swings to the front of the fiber optic connector and presses and fixes the fiber optic connector inside the connecting frame.

[0010] As a preferred embodiment of the present invention, both sides of the front of the machine body are fixedly connected to the extrusion rods, the front end of the extrusion rods extends to the bottom of the shaft, and both ends of the shaft are fixedly connected to the force plates located outside the connecting block. The force plates are located at the top of the extrusion rods and slide in contact with the extrusion rods. When the connecting frame moves to the rear, it can carry the force plates to contact the extrusion rods and push the force plates to flip.

[0011] As a preferred embodiment of the present invention, the release structure includes brackets fixedly connected to both sides of the connecting frame, and a push plate is movably connected to the inner side of the brackets via a pin. The end of the push plate away from the brackets extends to the top of the fiber optic connector and can contact the latch on the top of the fiber optic connector when swinging.

[0012] As a preferred embodiment of the present invention, a handle is fixedly connected to the front of the connecting frame, a gripping frame is slidably connected inside the handle, a protrusion is fixedly connected to the back of the gripping frame, a linkage plate is fixedly connected to the bottom of the push plate, and the side of the linkage plate away from the push plate extends to the front side of the protrusion. When the gripping frame moves forward carrying the protrusion, it can squeeze the linkage plate to cause the linkage plate to flip and swing with the push plate.

[0013] As a preferred embodiment of the present invention, sliders are fixedly connected to both sides of the grip frame, and grooves are provided on both sides of the inner wall of the handle, with the grooves and sliders being slidably connected.

[0014] As a preferred embodiment of the present invention, a data transmission device for system data backup and recovery and its method of use include the following steps: Preparation and loading: The operator inserts all the fiber optic connectors that need to be connected into the corresponding slots of the movable connection frame; Connection and Locking: The operator holds the handle on the front of the connection frame and pushes the entire connection frame smoothly toward the machine body. During this process, the force plates at both ends of the shaft fixed on the crossbeam contact the pressing rod on the machine body. Under the guidance of the pressing rod, the force plates drive the shaft to rotate. The multiple pressure plates installed on the shaft swing upward synchronously, pressing and fixing all fiber optic connectors into the connection frame from the front, completing the mechanical locking of all connectors. At the same time, the connection frame moves synchronously with all fiber optic connectors, so that they are accurately inserted into their respective hard disk data interfaces. Unlocking and Separating: When disconnection is required, the operator pulls the gripping frame in the handle forward. The movement of the gripping frame pushes the linkage plate through the protrusion on its back. The linkage plate then drives the push plate at the top of the connection frame to flip downward in sync. At the same time, the end of the push plate presses the latch at the top of each fiber optic connector, realizing the synchronous release of the locking mechanism of all connectors. After unlocking, continue to pull the connection frame backward to pull all fiber optic connectors out of the hard drive interface at once.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention integrates the insertion and removal operations of multiple fiber optic connectors into two actions: pushing and pulling a single handle, through a combination of a connecting frame, a positioning structure, and a release structure. Operators no longer need to handle each connector individually, thus avoiding the need for identification and manual operation among multiple adjacent and visually similar fiber optic connectors. This eliminates the problems of misinsertion, missed insertion, or incomplete connection caused by difficulties in visual identification and limited operating space, improving operational accuracy and reducing the risk of communication failures due to connection errors.

[0016] 2. This invention forces the shaft to rotate through the contact between the pressing rod and the force plate, causing all pressure plates to swing synchronously, thus pressing the fiber optic connector firmly into the connection frame from the front. This process ensures that all connectors remain aligned and reach the same insertion depth when inserted into the hard drive data interface. It avoids situations where individual connectors are tilted, not fully inserted, or the locking mechanism is not engaged, which may occur during manual installation. This achieves consistency and stability in all physical connection states, providing a reliable electrical connection foundation for data transmission.

[0017] 3. This invention shortens the maintenance process, which previously required individually plugging and unplugging numerous fiber optic connectors, to the time required to plug and unplug a single connection unit. This significantly reduces the system's offline time window due to maintenance, improving the availability of storage devices. Simultaneously, this standardized operating procedure lowers the skill requirements for maintenance personnel, eliminating the need for memorizing or complexly recording individual port identifiers, enabling maintenance tasks to be performed quickly and systematically.

[0018] 4. This invention utilizes a forward-pulling gripping frame to drive the protrusion and linkage plate during the pull-out operation, causing all push plates to swing downwards synchronously and simultaneously press the latches of each fiber optic connector. This avoids the need to press each latch individually, preventing mechanical damage to the latches due to improper operation or tool use. Furthermore, all connectors remain fixed within the connection frame throughout the pull-out process, maintaining their original correspondence with the switch ports. This eliminates the need to re-verify port mappings during reconnection, simplifying the system recovery process. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 6 As shown, this invention provides a data transmission device and its usage method for system data backup and recovery. This device enables rapid, synchronous, and batch plugging and unplugging of fiber optic interfaces for multiple hard disk arrays in data center or server cluster environments. This avoids the tediousness and errors of operating one by one in densely cabled environments, ensuring the efficiency and reliability of physical connections in data backup and recovery tasks. The device as a whole consists of four parts working together: a main body 1, a movable connection frame 5, an integrated positioning and locking mechanism, and a synchronous release mechanism.

[0023] The main body of the unit 1 adopts a standard rack-mount structure, formed by bending and welding sheet metal. The front panel is stamped to form several regular rectangular mounting positions. The hard disk assembly 2 is inserted into the corresponding mounting positions on the front of the unit 1 via guide rails on both sides, and is initially fixed by elastic clips at the rear. The front panel of the hard disk assembly 2 integrates a high-speed fiber optic data interface 3, which is a standardized LC or SC type fiber optic socket with gold-plated internal spring contacts to ensure the stability and low loss of high-frequency signal transmission.

[0024] The movable connection frame 5 is the core operating unit of the device, used for the clustered management of multiple fiber optic connectors 4. The connection frame 5 is a rectangular frame injection molded from high-strength engineering plastic, with guide ribs on its inner upper and lower edges for alignment with the body 1 during pushing. Inside the frame are a series of slots precisely corresponding to the positions of the hard disk data interfaces 3, each slot containing a guide sleeve to accommodate and initially secure the fiber optic connectors 4. A handle 16 is fixedly installed at the center of the front of the connection frame 5; the handle 16 has a hollow cavity structure for easy gripping and force application. A crossbeam 6 is fixedly connected to the bottom of the connection frame 5 by screws. The crossbeam 6 is a long strip of metal plate, extending towards both sides of the body 1. On the left and right sides of the front panel of the body 1, a movable block 7 is fixed, with smooth through holes machined inside. A cylindrical sliding rod 8 is fixed to each end of the crossbeam 6; the end of the sliding rod 8 away from the crossbeam 6 passes through the through hole of the corresponding movable block 7 and slides with the through hole, allowing the entire connection frame 5 assembly to move smoothly back and forth horizontally relative to the body 1.

[0025] An integrated positioning and locking mechanism is installed at the bottom of the connecting frame 5 assembly to automatically lock all fiber optic connectors 4 during the advancement of the connecting frame 5. This mechanism mainly includes a shaft 10, a set of pressure plates 11, and a triggering assembly. The shaft 10 is a round steel shaft extending through the bottom width of the connecting frame 5, with its two ends movably connected to two connecting blocks 9 fixed to the bottom of the crossbeam 6 via bearings, allowing the shaft 10 to rotate freely. Multiple pressure plates 11 are fixed at equal intervals on the surface of the shaft 10, the number of pressure plates 11 matching the number of slots in the connecting frame 5. Each pressure plate 11 is approximately L-shaped, with its short side fixed to the shaft 10 and its long side swinging as the shaft 10 rotates. When the shaft 10 is in its initial position, the long side of the pressure plate 11 hangs perpendicular to the side of the fiber optic connector 4; after the shaft 10 rotates a certain angle, the long side of the pressure plate 11 swings upward to the front of the fiber optic connector 4, creating downward pressure. The triggering assembly consists of a pressing rod 12 and a force-bearing plate 13. On the front of the body 1, on both sides behind the shaft 10, there is an upwardly inclined pressing rod 12, the front end of which has a smooth arc guide surface. At both ends of the shaft 10, on the outside of the connecting block 9, there is a force plate 13, which is fan-shaped and whose lower edge slides in contact with the arc guide surface of the pressing rod 12. When the connecting frame 5 is pushed toward the body 1, the crossbeam 6 drives the shaft 10 and the force plate 13 to move synchronously. The lower edge of the force plate 13 slides along the inclined surface of the pressing rod 12. The force generated by this sliding contact forces the two force plates 13 and the shaft 10 to rotate, thereby driving all the pressure plates 11 to swing upward synchronously, firmly pressing a row of fiber optic connectors 4 into the slots of the connecting frame 5, thus completing the mechanical locking.

[0026] A synchronous release mechanism is installed on the top of the connecting frame 5 assembly to synchronously release the locking latches of all fiber optic connectors 4 when the connection needs to be disconnected. This mechanism mainly includes a push plate 15, a linkage component, and an operating component. On the left and right sides of the top of the connecting frame 5, a bracket 14 is fixedly attached. The push plate 15 is movably connected to the bracket 14 via a pin, and the front end of the push plate 15 can swing downwards. Multiple push plates 15 achieve synchronous action through a connecting rod, which passes through and is fixed to the holes in the middle of all push plates 15. The operating component is integrated into the handle 16. A gripping frame 17 is slidably installed in the inner cavity of the handle 16, and a protrusion 18 is fixed to the back of the gripping frame 17. Slider blocks 20 are provided on both sides of the gripping frame 17, forming a sliding guide with the sliding groove 21 on the inner wall of the handle 16. At the bottom of the push plate 15, a linkage plate 19 is fixedly connected, extending horizontally backwards, with its end positioned just in front of the protrusion 18 on the back of the gripping frame 17. When unlocking is required, the operator pulls the gripping frame 17 forward. The gripping frame 17 moves the protrusion 18 on its back forward, and the protrusion 18 pushes the linkage plate 19. The linkage plate 19 then drives the push plate 15 to flip downward around its pivot pin. The downward pressing surface at the front end of the push plate 15 simultaneously presses down on the elastic latches at the top of each fiber optic connector 4, causing all latches to unlock synchronously. The handle 16 has a return spring inside, which automatically resets the gripping frame 17 after it is released.

[0027] The initial deployment and connection process for the equipment is as follows: The operator inserts all fiber optic connectors 4 that need to be connected to the equipment into the corresponding slots of the movable connection frame 5 one by one in sequence, ensuring that the connectors are in contact with the bottom of the slots. Then, the operator holds the handle 16 on the front of the connection frame 5 and pushes the entire connection frame 5 assembly smoothly towards the body 1. During this process, the connection frame 5 is smoothly guided by the sliding rod 8 within the movable block 7, ensuring that all fiber optic connectors 4 are precisely aligned with the hard disk data interface 3. As the connection frame 5 is pushed forward, the force plates 13 fixed at both ends of the shaft 10 contact the pressing rod 12 on the body 1. Under the guidance of the inclined surface of the pressing rod 12, the force plates 13 drive the shaft 10 to rotate. The rotation of the shaft 10 drives all the L-shaped pressure plates 11 on it to swing upward synchronously, pressing and fixing the entire row of fiber optic connectors 4 into the connection frame 5 from the front, completing the mechanical locking of all connectors in one go. At the same time, the connection frame 5 moves as a whole with the locked fiber optic connectors 4, so that they are smoothly and synchronously fully inserted into their respective corresponding hard disk data interfaces 3, completing the electrical connection.

[0028] The equipment disconnection and maintenance procedure is as follows: When disconnection is required for hard drive replacement or system maintenance, the technician first pulls forward the gripping frame 17 inside the handle 16. The movement of the gripping frame 17 pushes the linkage plate 19 through the protrusion 18 on its back, and the linkage plate 19 then drives all the push plates 15 at the top of the connection frame 5 to flip downwards simultaneously. The downward pressing surface at the end of the push plate 15 simultaneously presses the latch on the top of each fiber optic connector 4, realizing the instantaneous synchronous release of all connector locking mechanisms. After the unlocking action is completed, continue to pull the connection frame 5 smoothly backward, and all fiber optic connectors 4 can be pulled out from the hard drive data interface 3 as a whole at once. During the pulling process, since the pressure plate 11 has not yet been reset, the fiber optic connectors 4 are still constrained within the connection frame 5, maintaining the original correspondence with the port, which is convenient for reconnection.

[0029] This device integrates the insertion and removal operations of multiple independent interfaces into two linear actions—pushing and pulling—of a single handle 16 through a mechanical linkage design, greatly simplifying maintenance operations in high-density fiber optic cabling environments. Its positioning and locking mechanism ensures consistency in insertion depth and contact pressure for all connectors, eliminating loose connections or poor contact caused by variations in manual operation. The synchronous release mechanism avoids repeated operation on individual fragile latches, reducing the risk of component damage. The entire device is robust and reliable, requiring no external power supply or precision tools, significantly shortening the system maintenance window and reducing reliance on operator technical skills. It is suitable for enterprise-level storage environments requiring frequent data migrations or disaster recovery drills.

[0030] During equipment maintenance, after removing the connecting frame 5, check whether the moving parts of the pressure plate 11 and push plate 15 are moving smoothly, and clean the dust from the slide rod 8 and slide groove 21. If any individual fiber optic connector 4 is damaged, it can be removed and replaced individually from the slot of the connecting frame 5 without disassembling the entire mechanism. All metal moving parts are protected with grease, and the engineering plastic parts have flame-retardant properties, meeting data center safety specifications.
