A computer network security intelligent control device

Abstract

The invention discloses a computer network security intelligent control device, which structure includes a display screen, an intelligent control cabinet, a cabinet door, a fingerprint lock, and a moving wheel. The display screen is fixedly installed on the upper end of the intelligent control cabinet, and the cabinet door is arranged at the front end of the intelligent control cabinet. The transmission end of the storage disk extends into the inside of the engaging slot frame, and the elastic force is applied by a compression spring to ensure that the engaging conductive sheets at the upper and lower ends are in tight elastic resistance to the upper and lower sides of the transmission end of the storage disk, thereby improving the firmness of the storage disk during data transmission and preventing data loss caused by the middle end during data transmission. Heat is dissipated to both sides through the outer shell and enters the inside of the heat collecting tank to be absorbed by the heat absorbing block and the heat dissipation plate at the same time. After the heat absorbing block absorbs the heat, its volume expands, so that the heat absorbed by the heat dissipation plate is away from the surrounding of the storage disk. After the heat is dissipated, the torsion shaft applies a reset torque to the opening and closing sheet, so that the opening and closing sheet is reset and rotated to close the heat dissipation hole, thereby preventing external dust from entering the heat dissipation hole.

Description

Technical Field

[0001] The present invention relates to the field of computer networks, and more specifically, to a computer network security intelligent control device. Background Art

[0002] A computer network refers to a plurality of computers and their external devices with independent functions in different geographical locations, connected through communication lines. A computer network security intelligent control device can transmit and store the computer's network security data and protect the network security data. However, since the computer network security intelligent control device needs to transmit and store the network security data through an internal storage disk, and the storage disk is installed inside the computer network security intelligent control device by snap-fitting, it is easy to disassemble and assemble the storage disk. However, the storage disk is prone to loosening when installed inside the intelligent control device for a long time, causing interruption in data transmission and loss of network security data. At the same time, multiple storage disks independently archive the data of multiple computers. Multiple storage disks work at the same time and generate more heat. The heat is discharged through the heat dissipation holes, and the heat dissipation holes are easily blocked due to dust accumulation, resulting in heat being difficult to discharge in time and accumulating around the storage disk, which easily leads to unstable storage disk data reading.

The transmission mechanism is arranged at the front end of the conduction port plate, and two of the fixed rod, magnetic sheet, limit block, spring and rebound plate are each provided, and are symmetrically installed at the front end of the transmission mechanism.

[0006] As a further improvement of the present invention, the transmission mechanism includes a locking slot frame, a fixing plate, a compression spring, and a locking conductive plate. The locking slot frame is arranged at the front end of the conduction port plate, and the front end of the locking slot frame is fixed to the rear end of the fixing rod. A fixing plate is provided on the inner side of the locking slot frame. The compression spring is installed between the fixing plate and the locking conductive plate, and the locking conductive plate is located on the inner side of the locking slot frame. The locking conductive plate is in conflict with the rear end of the storage disk. Two of the fixing plate, compression spring and locking conductive plate are each provided, and are symmetrically installed inside the locking slot frame in an upper and lower manner.

[0007] As a further improvement of the present invention, the heat dissipation mechanism includes a heat collecting tank, a heat absorbing block, a heat dissipation plate, a telescopic hose, and an anti-blocking mechanism. The heat collecting tank is embedded in the inner and outer sides of the cabinet, and the heat collecting tank is arranged on the outer side of the shell. A heat absorbing block is arranged inside the left side of the heat collecting tank, and the heat absorbing block is installed on the left end of the heat dissipation plate.

[0009] The beneficial effects of the present invention are:

[0010] 1. Ten storage disks can independently archive the data of ten computers at the same time. The transmission end of the storage disk extends into the inside of the card slot frame, and the elastic force is applied by the compression spring to ensure that the card conduction sheets at the upper and lower ends are in tight elastic resistance to the upper and lower sides of the transmission end of the storage disk, thereby improving the firmness of the storage disk during data transmission, avoiding the loosening of the storage disk, and preventing data loss caused by the middle of the data transmission.

[0011] 2. Heat is dissipated to both sides through the outer shell and enters the heat collecting tank to be absorbed by the heat absorbing block and the heat sink at the same time. After the heat absorbing block absorbs the heat, its volume expands. The expanded heat absorbing block applies an outward thrust to the heat sink, so that the heat absorbed by the heat sink is away from the surrounding of the storage disk, accelerating the dissipation of heat. After the heat is dissipated, the torsion shaft applies a reset torque to the opening and closing piece, so that the opening and closing piece is reset and rotated to close the heat dissipation hole, preventing external dust from entering the heat dissipation hole and ensuring that the heat dissipation hole performs normal heat dissipation work.

[0024] Among them, the storage mechanism g2 includes a shell g23, a conduction port plate g28, a storage disk g25, and a clamping mechanism g21. The shell g23 is fixedly installed in the middle end of the cabinet g3, and the conduction port plate g28 is embedded in the rear end of the inner side of the shell g23. The front end of the conduction port plate g28 is connected with the clamping mechanism g21, and the rear end of the storage disk g25 is clamped and installed in the clamping mechanism g21. The storage disk g25 is installed in the front end of the shell g23 with a clearance fit. A heat dissipation mechanism g5 is provided on the outside of the shell g23. There are ten storage disks g25 in total, and five of them are installed in the left and right inner sides of the shell g23 in a group, and the ten storage disks g25 are clamped and connected with ten clamping mechanisms g21 respectively, and the rear ends of the ten clamping mechanisms g21 are conductively connected with the conduction port plate g28, so that the ten storage disks g25 can independently archive the data of ten computers.

[0025] Among them, the locking mechanism g21 includes a transmission mechanism 1z, a fixed rod 1b, a magnetic sheet 1c, a limit block 1h, a spring 1t, and a rebound plate 1x. The front end of the transmission mechanism 1z is fixed to the rear end of the fixed rod 1b, and the front end of the fixed rod 1b is clearance-fitted and penetrates the interior of the magnetic sheet 1c. The front end of the fixed rod 1b is provided with a limit block 1h, and the limit block 1h is slidably installed in the interior of the magnetic sheet 1c. The spring 1t is installed between the magnetic sheet 1c and the rebound plate 1x. The rebound plate 1x is arranged on the outside of the front end of the fixed rod 1b.

The compression springs z2 at the upper and lower ends apply elastic force to the upper and lower locking conductive plates z4, so that the locking conductive plate z4 is tightly in contact with the upper and lower sides of the transmission end of the storage disk g25, thereby improving the firmness of the storage disk g25 during data transmission and preventing data loss caused by mid-end during data transmission.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, in the process of transmitting and storing the network security data of the computer, by snapping the storage disk g25 into the shell g23, ten storage disks g25 can independently archive the data of ten computers at the same time. In the process of snapping the storage disk g25 into the shell g23, the storage disk g25 and the magnetic sheet 1c are magnetically adsorbed, and at the same time, the transmission end of the storage disk g25 extends into the inside of the snap-fit ​​groove frame z6, and the snap-fit ​​conductive sheets z4 at the upper and lower ends are in contact with the upper and lower sides of the transmission end of the storage disk g25, and the elastic force is applied by the compression spring z2 to ensure that the snap-fit ​​conductive sheets z4 at the upper and lower ends are in tight elastic contact with the upper and lower sides of the transmission end of the storage disk g25, so that the snap-fit ​​conductive sheets z4 at the upper and lower ends are in tight elastic contact with the upper and lower sides of the transmission end of the storage disk g25, so that the snap-fit ​​conductive sheets The transmission ends of z4 and the storage disk g25 are able to conduct electricity and are connected to the conduction port plate g28 through the compression spring z2 and the fixing plate z8 to perform network secure data transmission, thereby improving the firmness of the storage disk g25 during data transmission, avoiding loosening of the storage disk g25, and preventing data loss caused by the middle of the data transmission. When the internal network security data of the storage disk g25 is fully stored, the storage disk g25 is replaced. During replacement, the storage disk g25 is pressed.

[0029] Embodiment 2:

[0030] As attached Figure 6 To Attachment Figure 7 As shown:

[0031] The heat dissipation mechanism g5 includes a heat collecting tank g53, a heat absorbing block g59, a heat dissipation plate g51, a telescopic hose g56, and an anti-blocking mechanism g57. The heat collecting tank g53 is embedded in the inner and outer sides of the cabinet g3, and the heat collecting tank g53 is arranged on the outer side of the shell g23. A heat absorbing block g59 is arranged inside the left side of the heat collecting tank g53, and the heat absorbing block g59 is installed on the left end of the heat dissipation plate g51. The heat dissipation plate g51 is installed inside the heat collecting tank g53. The right side of the heat dissipation plate g51 is fixed to the left end of the telescopic hose g56, and the right side of the telescopic hose g56 is arranged on the cabinet. g3 inner wall, the anti-blocking mechanism g57 is embedded in the cabinet g3, and the right end of the heat sink g51 is located inside the anti-blocking mechanism g57, and there are seven heat-absorbing blocks g59, which are vertically equidistantly distributed on the left side of the heat sink g51, and the heat-absorbing blocks g59 are made of metal zinc and have a high thermal expansion coefficient. They can absorb the heat generated by the storage disk g25 and expand in volume, thereby pushing the heat sink g51 to move, speeding up the discharge of heat absorbed by the heat sink g51, and preventing heat from accumulating around the storage disk g25.

[0032] Among them, the anti-blocking mechanism g57 includes a heat dissipation hole 73, a torsion shaft 7n, and an opening and closing piece 7b. The heat dissipation hole 73 is embedded in the cabinet g3, and the opening and closing piece 7b is located on the right side of the heat dissipation hole 73. The upper end of the opening and closing piece 7b is hinged to the inside of the cabinet g3 through the torsion shaft 7n. The right end of the heat dissipation plate g51 is located in the anti-blocking mechanism g57, and the left side of the opening and closing piece 7b is in conflict with the right end of the heat dissipation plate g51. The lower end of the heat dissipation hole 73 is in conflict with the left side of the lower end of the opening and closing piece 7b. The rotation angle of the opening and closing piece 7b is limited to prevent the opening and closing piece 7b from rotating to the left to cause external dust to enter the heat dissipation hole 73, thereby ensuring that the heat dissipation hole 73 performs normal heat dissipation work.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the present invention, when ten storage disks g25 are simultaneously performing network data transmission and storage, a large amount of heat is generated. The heat is dissipated to both sides through the outer shell g23 and enters the heat collecting tank g53 to be absorbed by the heat absorbing block g59 and the heat sink g51 at the same time. After the heat absorbing block g59 absorbs the heat, its volume expands. The expanded heat absorbing block g59 applies an outward thrust to the heat sink g51, so that the heat absorbed by the heat sink g51 is away from the surrounding of the storage disk g25, accelerating the dissipation of heat, and avoiding the accumulation of heat around the storage disk g25, causing the temperature to be too high, resulting in unstable data reading of the storage disk g25, and at the same time, the heat sink g51 pushes outward. During the movement of the side, an outward thrust is applied to the opening and closing piece 7b. At this time, the opening and closing piece 7b rotates outward around the torsion axis 7n. At this time, the heat dissipation hole 73 is in a conductive state to discharge the heat. After the heat is discharged, the cooling volume of the heat absorption block g59 shrinks and returns to its original state. At this time, the telescopic hose g56 pushes the heat sink g51 to reset. The thrust applied by the heat sink g51 to the opening and closing piece 7b disappears, and a reset torque is applied to the opening and closing piece 7b through the torsion axis 7n, so that the opening and closing piece 7b is reset and rotated to close the heat dissipation hole 73, preventing external dust from entering the heat dissipation hole 73, and ensuring that the heat dissipation hole 73 performs normal heat dissipation work.
