Description

Technical Field

[0001] The present invention relates to the technical field of data storage devices, and particularly to a big data storage device with a protection mechanism. Background Art

[0002] Big data, a term in the IT industry, refers to a data set that cannot be captured, managed, and processed by conventional software tools within a certain time range. It is a massive, high-growth-rate, and diverse information asset that requires new processing models to have stronger decision-making power, insight discovery ability, and process optimization ability; a storage device is a general term for electronic, magnetic, laser, chemical, etc. products used for temporarily storing or long-term storing data. Generally, a computer contains ROM, RAM, hard disks, optical discs, and attached drives, etc. General storage devices are divided into internal storage and external storage;

A heat dissipation frame is fixedly connected to the interior of the protective shell. Protective covers are symmetrically and fixedly connected to both sides of the heat dissipation frame. A drive shaft is inserted into the interior of each of the two protective covers, and the other end of the drive shaft is rotatably connected to the inner wall of the protective shell.

[0010] A driven toothed plate is sleeved on the outer portion of the drive shaft away from the heat dissipation fan. A reinforcement mechanism is meshed with the outer surface of the driven toothed plate. An anti - detachment mechanism is sleeved on the side of the driven toothed plate away from the protective shell.

A limiting plate is fixedly connected to the end of the hollow spring away from the moving plate. A guiding plate is sleeved on the outer portion of the moving plate, and one side of the guiding plate is fixedly connected to the inner wall of the protective shell. Positioning pull rods are movably connected to both ends of the side of the moving plate near the hollow spring. The other ends of the two positioning pull rods are movably connected to fixing plates.

[0012] Preferably, the anti - detachment mechanism further includes a moving slider. A clamping plate is fixedly connected to the side of the moving slider away from the fixing plate. A limiting spring is fixedly connected to the interior of the clamping plate. A pressing plate is fixedly connected to the end of the limiting spring away from the clamping plate, and the pressing plate cooperates with the plug socket.

[0013] Preferably, the reinforcement mechanism includes a gear plate. A transmission screw rod is inserted into the interior of the gear plate. A shaft sleeve is sleeved on the end of the transmission screw rod located outside the protective shell. Guide rods are symmetrically inserted into the interior of the shaft sleeve. A linkage rod is fixedly connected to the outer surface of the shaft sleeve. A fixed block is fixedly connected to the end of the linkage rod away from the shaft sleeve. A telescopic rod is fixedly connected to the side of the fixed block close to the protective shell. A positioning suction cup is fixedly connected to the side of the fixed block away from the telescopic rod. A hollow rod is sleeved on the outer portion of the end of the telescopic rod away from the fixed block.

[0014] Preferably, one side of the limiting plate is fixedly connected to the interior of the protective shell. A moving slider is fixedly connected to the side of the fixing plate close to the inner wall of the protective shell. The guiding plate is slidably connected to the moving plate. A through - hole matching the drive shaft is opened in the interior of the coaxial plate.

[0015] Preferably, one end of the driving screw penetrates through the inside of the protective shell and is fixedly connected to the bushing.

When the pressing plate contacts the data head, the data head presses the pressing plate, causing the limiting spring on the pressing plate to undergo elastic deformation. Due to the mutual action of forces, the pressing plate pushes the data head with a reaction force, making the data head tightly connected to the plug head, thus achieving the effect of automatic anti-detachment and reinforcement, avoiding the detachment of the data head during the operation of the device, ensuring stable data transmission, and helping to improve the working efficiency of the device;

[0019] (2) Through the mutual cooperation and linkage among the driving shaft, the driven toothed plate and the reinforcement mechanism, the problem of poor stability of the device is solved. Through the transmission between gears, the linkage rod drives the fixed block to move accordingly, and at the same time, the positioning suction cup moves synchronously with the fixed block, so that the positioning suction cup adsorbs on the wall surface. The adsorption of the positioning suction cup on the wall surface increases the firmness between the device and the wall surface and improves the stability of the device, thus achieving the effect of automatically reinforcing the device.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to Figures 1-8As shown in the figure, the present invention is a big data storage device with a protection mechanism, including a protection shell 1. A heat dissipation mesh plate 2 is fixedly connected to the front surface of the protection shell 1. Protection frames 3 are fixedly connected to both sides of the protection shell 1. A positioning rod 4 is inserted into the interior of the protection frame 3. The protection frame 3 is installed inside the protection shell 1 manually. At the same time, the positioning rod 4 is locked by rotating the protection frame 3, so that the positioning rod 4 tightly wraps around the outside of the protection shell 1, thereby protecting the protection shell 1 with the positioning rod 4, strengthening the firmness of the protection shell 1, avoiding damage to the protection shell 1 caused by external impact, and thus achieving the effect of increasing the service life of the device. Plug sockets 5 are provided on both sides of the protection shell 1. A positioning frame 6 is fixedly connected to one side of the protection shell 1. A heat dissipation frame 7 is fixedly connected to the interior of the protection shell 1. Protective covers 8 are symmetrically and fixedly connected to both sides of the heat dissipation frame 7. A drive shaft 9 is inserted into the interior of each of the two protective covers 8, and the other end of the drive shaft 9 is rotatably connected to the inner wall of the protection shell 1. A heat dissipation fan 10 is sleeved on the outside of the drive shaft 9 near the protective cover 8. After the device is installed, by turning on the external power supply, the device starts to work. As the device works, the motor drives the drive shaft 9 on the heat dissipation frame 7 to rotate, and then the external heat dissipation fan 10 dissipates heat from the device;

[0033] One end of the drive shaft 9 away from the radiator fan 10 is externally sleeved with a driven toothed plate 11, and the outer surface of the driven toothed plate 11 is meshed and connected with a reinforcement mechanism 13. As the drive shaft 9 rotates, the drive shaft 9 drives the driven toothed plate 11 to rotate accordingly. During the rotation of the driven toothed plate 11, through the transmission between gears, the driven toothed plate 11 drives the reinforcement mechanism 13 to rotate. The reinforcement mechanism 13 includes a gear plate 131, a transmission screw 132 is inserted inside the gear plate 131, a sleeve 133 is sleeved on one end of the transmission screw 132 located outside the protective shell 1, guide rods 134 are symmetrically inserted inside the sleeve 133, a linkage rod 135 is fixedly connected to the outer surface of the sleeve 133, a fixed block 136 is fixedly connected to one end of the linkage rod 135 away from the sleeve 133, a telescopic rod 138 is fixedly connected to one side of the fixed block 136 close to the protective shell 1, a positioning suction cup 137 is fixedly connected to one side of the fixed block 136 away from the telescopic rod 138, and a hollow rod 139 is sleeved on the outside of one end of the telescopic rod 138 away from the fixed block 136. That is, the driven toothed plate 11 drives the gear plate 131 to rotate, and during the rotation of the gear plate 131, the internal transmission screw 132 is driven to rotate synchronously, and the transmission screw 132 drives the sleeve 133 at the other end outside to move accordingly. Due to the restriction of the guide rod 134, the sleeve 133 moves horizontally on the outside of the guide rod 134. During the movement of the sleeve 133, the sleeve 133 drives the linkage rod 135 to move accordingly, the linkage rod 135 drives the fixed block 136 to move accordingly, the fixed block 136 drives the telescopic rod 138 to move outward inside the hollow rod 139, and at the same time, the positioning suction cup 137 moves synchronously with the fixed block 136, so that the positioning suction cup 137 contacts the wall surface after moving. As the positioning suction cup 137 contacts the wall surface, the acting force between the positioning suction cup 137 and the wall surface becomes larger, so that the gear plate 131 idles on the outside of the transmission screw 132. In addition, the positioning suction cup 137 adsorbs on the wall surface, and the positioning suction cup 137 adsorbing on the wall surface increases the firmness between the device and the wall surface and improves the stability of the device, thus achieving the effect of automatically reinforcing the device.

[0034] Embodiment 2:

[0035] When the existing device is in use, the data cable is inserted into the device. After the data cable is directly inserted into the device, the device vibrates continuously during operation, which causes the data head to become loose, resulting in the device being unable to work properly. At the same time, the loose data head needs to be re-reinforced, wasting time. Moreover, the loosening of the data head is likely to cause data loss and data transmission interruption. Therefore, the existing problems need to be solved urgently.

[0036] When the device is working, by turning on the external power supply, the device starts to work, the motor drives the drive shaft 9 on the heat dissipation rack 7 to rotate, and then the external radiator fan 10 dissipates heat from the device. The drive shaft 9 drives the driven tooth plate 11 to rotate accordingly. During the rotation of the driven tooth plate 11, a anti-disengagement mechanism 12 is sleeved on the side of the driven tooth plate 11 away from the protective shell 1. The anti-disengagement mechanism 12 includes a coaxial plate 121. One end of the coaxial plate 121 away from the drive shaft 9 is movably connected to a crank connecting rod 122. One end of the crank connecting rod 122 away from the coaxial plate 121 is movably connected to a moving plate 123. A hollow spring 124 is fixedly connected to the upper surface of the moving plate 123. One end of the hollow spring 124 away from the moving plate 123 is fixedly connected to a limiting plate 125. One side of the limiting plate 125 is fixedly connected to the inside of the protective shell 1. A guiding plate 127 is sleeved outside the moving plate 123, and one side of the guiding plate 127 is fixedly connected to the inner wall of the protective shell 1. Both ends of the side of the moving plate 123 close to the hollow spring 124 are movably connected to positioning pull rods 126. One end of each of the two positioning pull rods 126 away from the moving plate 123 is movably connected to a fixing plate 128. A moving slider 129 is fixedly connected to the side of the fixing plate 128 close to the inner wall of the protective shell 1. A clamping plate 120 is fixedly connected to the side of the moving slider 129 away from the fixing plate 128. A limiting spring 01 is fixedly connected to the inside of the clamping plate 120. One end of the limiting spring 01 away from the clamping plate 120 is fixedly connected to a pressing plate 02, and the pressing plate 02 cooperates with the plug head 5. Thus, during the rotation of the driven tooth plate 11, the coaxial plate 121 is driven to rotate by the static friction force between it and the driven tooth plate 11. When the coaxial plate 121 rotates, the crank connecting rod 122 is driven to move accordingly. When the crank connecting rod 122 moves, it pulls the moving plate 123 at the other end, and the moving plate 123 slides vertically downward inside the guiding plate 127;

[0037] As the moving plate 123 moves, the positioning pull rods 126 on both sides are driven to move along with the moving plate 123 during the movement. At the same time, the hollow spring 124 undergoes elastic deformation. With the movement of the positioning pull rods 126, the two positioning pull rods 126 respectively pull the fixed plates 128 on both sides, causing the fixed plates 128 to drive the moving sliders 129 to slide inside the protective shell 1, making the moving sliders 129 on both sides of the plug head 5 move closer to the middle. As the moving sliders 129 move, the moving sliders 129 drive the clamping plates 120 to move synchronously, and the moving sliders 129 drive the pressing plate 02 to move. During the movement of the pressing plate 02, the pressing plate 02 contacts the data head, causing the data head to press the pressing plate 02, and the limiting spring 01 on the pressing plate 02 undergoes elastic deformation. Due to the interaction of forces, the pressing plate 02 pushes the data head with a reaction force, making the data head tightly connected to the plug head 5. When the external force increases, the driven gear plate 11 cannot drive the coaxial plate 121 to rotate through static friction, and the coaxial plate 121 idles outside the driven gear plate 11, thus achieving the effect of automatic anti - detachment and reinforcement, avoiding the detachment of the data head during the operation of the device, ensuring stable data transmission, helping to improve the working efficiency of the device, and solving the problem of easy detachment of the data head;

[0038] A big - data storage device with a protection mechanism. The usage method of the big - data storage device with a protection mechanism includes the following steps:

[0039] Step 1: By turning on the external power supply, the device starts to work. As the device operates, the motor drives the drive shaft 9 to rotate, and then the radiator fan 10 outside the drive shaft 9 dissipates heat from the device;

[0040] Step 2: As the drive shaft 9 rotates, the drive shaft 9 drives the external driven gear plate 11 to rotate synchronously. Through the transmission between gears, the driven gear plate 11 drives the gear plate 131 to work, causing the bushing 133 outside the gear plate 131 to move horizontally. Through the transmission between mechanisms, the positioning suction cup 137 adsorbs on the wall surface, thereby strengthening the device;

[0041] Step 3: When the protective cover 8 is working, the drive shaft 9 drives the coaxial plate 121 to move along with it. The coaxial plate 121 pulls the moving plate 123 to slide inside the guide plate 127 through the crank - connecting rod 122. Through the linkage between mechanisms, the moving sliders 129 on both sides of the plug head 5 move closer to the middle;

[0042] Step 4: As the moving sliders 129 on both sides of the plug head 5 move, the moving sliders 129 drive the clamping plates 120 to move accordingly, so that the clamping plates 120 limit and clamp the data cable. At the same time, during the movement of the clamping plates 120, the pressing plate 02 presses the data head. Due to the mutual action of forces, the acting force of the pressing plate 02 pushes back on the data head, making the connection of the data head more secure.

[0043] The working process and principle of the present invention are as follows:

[0044] By turning on the external power supply, the device starts to work, and the motor drives the drive shaft 9 on the heat dissipation frame 7 to rotate. Then, the external heat dissipation fan 10 dissipates heat from the device. The drive shaft 9 drives the driven toothed plate 11 to rotate accordingly. Through the transmission between gears, the driven toothed plate 11 drives the gear plate 131 to rotate, and the transmission screw 132 drives the sleeve 133 at the other end outside to move accordingly. Due to the limitation of the guide rod 134, the sleeve 133 moves horizontally outside the guide rod 134. The sleeve 133 drives the linkage rod 135 to move accordingly, the linkage rod 135 drives the fixed block 136 to move accordingly, the fixed block 136 drives the telescopic rod 138 to move outward inside the hollow rod 139. At the same time, the positioning suction cup 137 moves synchronously with the fixed block 136, and the positioning suction cup 137 adsorbs on the wall surface. The adsorption of the positioning suction cup 137 on the wall surface increases the firmness between the device and the wall surface and improves the stability of the device, thus achieving the effect of automatically strengthening the device.

[0045] As the drive shaft 9 drives the driven toothed plate 11 to rotate, the driven toothed plate 11 drives the coaxial plate 121 to rotate accordingly. During the movement of the crank connecting rod 122, it pulls the moving plate 123 at the other end, so that the moving plate 123 slides vertically downward inside the guide plate 127. During the movement of the moving plate 123, it drives the positioning pull rods 126 on both sides to move accordingly. At the same time, the hollow spring 124 undergoes elastic deformation. The two positioning pull rods 126 respectively pull the fixed plates 128 on both sides, and the fixed plates 128 drive the moving sliders 129 to slide inside the protective shell 1, so that the moving sliders 129 on both sides of the plug head 5 move closer to the middle. The moving sliders 129 drive the pressing plate 02 on the clamping plate 120 to move accordingly. When the pressing plate 02 contacts the data head, the data head presses the pressing plate 02, causing the limiting spring 01 on the pressing plate 02 to undergo elastic deformation. Due to the mutual action of forces, the reaction force of the pressing plate 02 pushes the data head, making the data head tightly connected to the plug head 5, thus achieving the effect of automatic anti - detachment and reinforcement, avoiding the detachment of the data head during the operation of the device, ensuring the stable transmission of data, helping to improve the working efficiency of the device, and solving the problem of easy detachment of the data head.

[0046] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
