Description

Technical Field

[0001] This utility model relates to the technical field of computer anti-spying, specifically a computer network security anti-spying screen mechanism. Background Technology

[0002] Computers, also known as PCs, are protected by network security privacy screens designed to prevent others from peeping at the computer screens being used, thus protecting user privacy.

[0003] A search revealed Chinese patent publication number CN222774786U, which discloses a computer network security anti-spyscreen mechanism, belonging to the field of computer anti-spyscreen technology. This mechanism includes a computer body and an anti-spyscreen component. The anti-spyscreen component includes a transmission component and a double-ended screw. One end of the transmission component is connected to the double-ended screw. Connecting blocks are threaded onto the surfaces of both threaded sections of the double-ended screw. These connecting blocks are slidably connected to the back of the computer body, and two fixing blocks are rotatably connected within each connecting block. An anti-spyscreen cloth is connected between the two fixing blocks. This invention, through the cooperation of the transmission component and the double-ended screw, causes the two connecting blocks to move in opposite directions. When the connecting blocks move a certain distance, the fixing blocks pop out, and the anti-spyscreen cloth opens, effectively blocking the display screen and reducing the likelihood of reduced screen brightness and reduced viewing brightness in bright light conditions.

[0004] However, when using this computer, it can only block the two ends of the computer, and the length of the privacy screen cannot be adjusted. This means that the privacy screen area cannot be adjusted according to the position of adjacent computers. In addition, the top of the computer is open, so when people stand up on both sides, they can still see the computer screen, which reduces the efficiency of the privacy screen device.

A connecting block is fixedly installed at the output end of each telescopic rod, and the distance between the two telescopic rods is greater than the height of the computer. The two ends of the first privacy cloth are fixedly connected to the sidewalls of the connecting blocks, and the rotating rods are positioned between the second privacy cloths to facilitate adjustment of the length of the first privacy cloth.

[0008] Preferably, the diameter of the limiting hole is smaller than the diameter of the sliding hole, the inner sidewall of the limiting hole is provided with a limiting groove, and multiple limiting blocks are fixedly installed at equal intervals on the sidewall of the lifting column. The sidewall of the limiting block is in contact with the inner sidewall of the limiting groove, and the distance between adjacent limiting blocks matches the thickness of the sidewall between the sliding hole and the limiting hole, thereby facilitating the limiting of the position of the lifting column.

[0009] Preferably, the upper end of each rotating rod passes through the upper side wall of the groove and extends to the top of the support column, and is fixedly connected to a handwheel. Each handwheel has a lever fixedly installed on its top surface, which facilitates the rotation of the rotating rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4This utility model provides a computer network security privacy screen mechanism, including a computer 1 and a second privacy screen 12. Support columns 2 are fixedly installed on both sides of the front end of the computer 1. Each support column 2 has a sliding hole 15 inside and a limiting hole 18 inside its top surface. The limiting hole 18 communicates with the sliding hole 15. A lifting column 9 is slidably connected inside the limiting hole 18. The upper end of each lifting column 9 extends through the limiting hole 18 to the upper end of the support column 2. Support rings 10 are sleeved on the outside of each of the two lifting columns 9, and are slidably connected to the lifting columns 9 in the lateral direction. The support rings 10 are located at the upper end of each support column 2. A frame 11 is fixedly installed between the two support rings 10. The second privacy screen 12 is fixedly installed inside the frame 11. The diameter of the limiting hole 18 is smaller than the diameter of the sliding hole 15. Limit grooves 17 are provided inside the side walls of the limiting hole 18. Multiple limiting blocks 16 are fixedly installed at equal intervals on the side walls of the lifting columns 9. The sidewalls of the limiting blocks 16 are all in contact with the inner sidewalls of the limiting grooves 17, and the distance between adjacent limiting blocks 16 matches the thickness of the sidewalls between the sliding holes 15 and the limiting holes 18. The upper ends of the lifting columns 9 are all fixedly installed with T-shaped rods 19. The upper end of the T-shaped rods 19 is parallel to the limiting blocks 16. When covering the top of the computer 1, the second privacy cloth 12 can be used to cover the top of the computer 1. At the same time, the height of the second privacy cloth 12 can be adjusted according to the user's height and comfort. The user holds the T-shaped rods 19 with both hands, and then rotates the lifting column 9 to move the position of the limiting blocks 16 to the position of the limiting grooves 17. Then, the lifting column 9 is lifted upwards until the height of the second privacy cloth 12 is adjusted to the required position. Then, the position of the lifting column 9 is rotated until the adjacent limiting blocks 16 are stuck on the sidewalls between the sliding holes 15 and the limiting holes 18, which can limit the position of the lifting column 9.

[0023] Example 2

[0024] To facilitate adjustment of the length of the first privacy screen 4, in this embodiment, as follows: Figure 1-4As shown, each of the front sidewalls of the support column 2 has a groove 3 inside, and a rotating rod 8 is rotatably connected inside each groove 3. A first privacy cloth 4 is wrapped around the outside of each rotating rod 8. Telescopic rods 5 are symmetrically fixedly installed on the front sidewalls of the support column 2. A connecting block 6 is fixedly installed at the output end of each telescopic rod 5, and the distance between the two telescopic rods 5 is greater than the height of the computer 1. Both ends of the first privacy cloth 4 are fixedly connected to the sidewalls of the connecting blocks 6. The rotating rod 8 is positioned between the second privacy cloths 12. The upper end of each rotating rod 8 penetrates the upper sidewall of the groove 3 and extends to the top of the support column 2, and is fixedly connected to a handwheel 14. A lever is fixedly installed on the top surface of each handwheel 14. A connecting rod 7 is fixedly installed between the side walls of the rod 13 and the two connecting blocks 6. The height of the first privacy cloth 4 is greater than the height of the computer 1. When adjusting the position of the computer 1, the connecting rod 7 is pulled forward to adjust the length of the telescopic rod 5. At the same time, the length of the first privacy cloth 4 can be extended. When shortening the length of the telescopic rod 5, it is necessary to first move it upward to the position of the second privacy cloth 12 so that the space between the second privacy cloth 12 and the computer 1 is sufficient for the user's hand to enter. Then, the handwheel 14 is rotated by the lever 13 to rotate the rotating rod 8, which can conveniently shorten the length of the first privacy cloth 4.

[0025] It should be noted that, in this embodiment, as Figure 1-4 As shown, when covering the top of computer 1, the second privacy screen 12 can cover the upper part of computer 1. The height of the second privacy screen 12 can be adjusted according to the user's height and comfort. The user holds the T-shaped rod 19 with both hands, then rotates the lifting column 9 to move the position of the limiting block 16 to the position of the limiting groove 17. Simultaneously, the lifting column 9 is pulled upwards until the height of the second privacy screen 12 is adjusted to the desired position. The lifting column 9 is then rotated until the adjacent limiting block 16 is engaged with the side wall between the sliding hole 15 and the limiting hole 18, thus limiting the position of the lifting column 9 and covering the computer 1. When adjusting the length, pull the connecting rod 7 towards the front end to adjust the length of the telescopic rod 5. This will lengthen the first privacy screen 4. To shorten the length of the telescopic rod 5, first move the second privacy screen 12 upwards to ensure sufficient space between the second privacy screen 12 and the computer 1 for the user's hand to enter. Then, rotate the handwheel 14 using the lever 13 to rotate the rotating rod 8, which will conveniently shorten the length of the first privacy screen 4. (Since the first privacy screen 4 generally does not need frequent length adjustment after use, the second privacy screen 12 is positioned above the handwheel 14 and will not affect its use.)
