Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a risk knowledge graph visualization display device. Background Technology

[0002] In today's digital information age, the visualization of risk knowledge graphs plays an important role in many fields such as security and education and training; however, existing risk knowledge graph visualization devices have many shortcomings.

[0003] Traditional display devices are usually fixed in height, which cannot meet the viewing needs of people of different heights, resulting in some viewers not being able to obtain a good viewing angle and reducing the efficiency of information transmission. The angle adjustment of existing display devices is mostly complicated to operate, requiring the use of additional tools or multiple people to complete, which consumes a lot of time and manpower. This makes it inconvenient to adjust the angle of the display screen, which limits the presentation of the displayed content and cannot fully show the whole picture of the risk knowledge graph, affecting the audience's understanding and reception of the knowledge. To solve the above problems, this application proposes a risk knowledge graph visualization display device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a risk knowledge graph visualization display device. The device utilizes a motor and a T-shaped lever to adjust the height and angle of the display screen. By adjusting the height of multiple risk knowledge graph display screens, different display needs can be met. Furthermore, by synchronously adjusting the angles of multiple display screens, the display effect is enhanced.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A risk knowledge graph visualization device includes a base, a hollow column fixedly connected to the top of the base, a lifting column slidably connected to the top of the hollow column, an adjustment mechanism between the hollow column and the lifting column, a top plate fixedly connected to the top of the lifting column, a motor fixedly connected to the top of the top plate, a threaded rod fixedly connected to the output end of the motor, the threaded rod passing through the top plate and rotatably connected to it, a lifting block threadedly connected to the outer wall of the threaded rod, the lifting block passing through the lifting column and slidably connected to it, a fixing ring fixedly connected to the outer wall of the lifting block, multiple pairs of fixing blocks fixedly connected to the top plate, each pair of fixing blocks rotatably connected to a risk knowledge graph display screen, a deflection rod rotatably connected to the back end of each risk knowledge graph display screen, and each deflection rod rotatably connected to the outer wall of the fixing ring.

[0007] Preferably, the adjusting mechanism includes a T-shaped lever that passes through and is rotatably connected to the hollow column. The T-shaped lever is coaxially fixedly connected to a driving bevel gear. A screw is rotatably connected to the inner bottom of the hollow column. A driven bevel gear is fixedly connected to the outer wall of the screw. The driving bevel gear meshes with the driven bevel gear. The screw is threadedly connected to the lifting column.

[0008] Preferably, a limiting block is fixedly connected to the outer wall of the lifting column. The limiting block has a rectangular cross-section and is located inside the hollow column and slidably connected to its inner wall.

[0009] Preferably, the outer wall of the screw is provided with an external thread, the lifting column is provided with a threaded groove, and the inner wall of the threaded groove is provided with an internal thread that mates with the external thread.

[0010] Preferably, the top of the lifting column is provided with a limiting groove, the lifting block passes through the limiting groove and is slidably connected thereto, and the bottom of the threaded rod is rotatably connected to the inner wall of the limiting groove.

[0011] Preferably, both ends of the risk knowledge graph display screen are rotatably connected to a rotating shaft, and the two rotating shafts are respectively fixedly connected to their corresponding fixed blocks.

[0012] Preferably, two solar panels and two batteries are fixedly connected to the top of the top plate.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. The adjustment mechanism drives the screw to rotate by rotating the T-shaped lever, which in turn drives the screw to rotate through the meshing of the active and driven bevel gears. The screw connection enables the lifting column to be raised and lowered, thereby adjusting the height of multiple risk knowledge graph display screens to meet different display needs.

[0015] 2. The screw rod is driven by a motor to rotate, and the lifting block moves up and down along the limit groove through the screw transmission, which in turn moves the fixed ring. The fixed block supports the risk knowledge graph display screen through the rotating shaft, allowing it to rotate around the shaft. When the fixed ring is raised and lowered, the deflection rod pushes the display screen to rotate around the rotating shaft, thereby realizing the synchronous adjustment of the angle of multiple display screens and improving the display effect.

[0016] 3. The solar panel converts solar energy into electrical energy, which is stored in the battery to power electrical components such as motors, achieving energy conservation and utilization, and is especially suitable for outdoor display scenarios; the design of this device in terms of height and angle adjustment and energy utilization effectively enhances the flexibility and convenience of risk knowledge graph display.

[0017] In summary, the height and angle of the display screen can be adjusted by using the motor and T-shaped lever. By adjusting the height of multiple risk knowledge graph display screens, different display needs can be met; and by adjusting the angles of multiple display screens simultaneously, the display effect can be improved.

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-2 A risk knowledge graph visualization display device includes a base 1 with four locking casters installed at the bottom for easy movement. The base 1 supports the entire device and facilitates its movement. A hollow column 2 is fixedly connected to the top of the base 1. A lifting column 3 is slidably connected to the top of the hollow column 2. A limit block is fixedly connected to the outer wall of the lifting column 3. The limit block has a rectangular cross-section and is located inside the hollow column 2 and slidably connected to its inner wall. The hollow column 2 provides guidance for the sliding of the lifting column 3. The limit block cooperates with the inner wall of the hollow column 2 to restrict the rotation of the lifting column 3, allowing it to move only along the axial direction of the hollow column 2.

[0023] An adjustment mechanism is provided between the hollow column 2 and the lifting column 3. The adjustment mechanism includes a T-shaped lever 4 that passes through the hollow column 2 and is rotatably connected to it. A driving bevel gear 5 is coaxially fixedly connected to the T-shaped lever 4. A screw 7 is rotatably connected to the inner bottom of the hollow column 2. A driven bevel gear 6 is fixedly connected to the outer wall of the screw 7. The driving bevel gear 5 and the driven bevel gear 6 mesh with each other. The screw 7 is threadedly connected to the lifting column 3. The outer wall of the screw 7 is provided with an external thread. A threaded groove is opened on the lifting column 3. The inner wall of the threaded groove is provided with an internal thread that matches the external thread. Rotating the T-shaped lever 4 drives the screw 7 to rotate through the meshing transmission of the driving bevel gear 5 and the driven bevel gear 6. The threaded connection between the screw 7 and the lifting column 3 causes the lifting column 3 to rise and fall along the hollow column 2, thereby realizing height adjustment.

[0024] A top plate 8 is fixedly connected to the top of the lifting column 3. The top plate 8 is used to install components such as the motor 9 and support the upper structure. The top of the top plate 8 is fixedly connected to the motor 9. A threaded rod 10 is fixedly connected to the output end of the motor 9. The threaded rod 10 passes through the top plate 8 and is rotatably connected to it. A lifting block 11 is threadedly connected to the outer wall of the threaded rod 10. The lifting block 11 passes through the lifting column 3 and is slidably connected to it. A limit groove 12 is opened at the top of the lifting column 3. The lifting block 11 passes through the limit groove 12 and is slidably connected to it. The limit groove 12 restricts the lifting block 11 to move only along the axial direction of the lifting column 3, ensuring that the lifting block 11 rises and falls smoothly. The bottom of the threaded rod 10 is rotatably connected to the inner wall of the limit groove 12. A fixing ring 13 is fixedly connected to the outer wall of the lifting block 11. The motor 9 drives the threaded rod 10 to rotate, and the lifting block 11 rises and falls along the limit groove 12 through threaded transmission, thereby driving the fixing ring 13 to move.

[0025] Multiple pairs of fixed blocks 14 are fixedly connected to the top plate 8. Each pair of fixed blocks 14 is rotatably connected to a risk knowledge graph display screen 15. Both ends of the risk knowledge graph display screen 15 are rotatably connected to a rotating shaft 16. The two rotating shafts 16 are fixedly connected to their corresponding fixed blocks 14. The fixed blocks 14 support the risk knowledge graph display screen 15 through the rotating shafts 16 and allow it to rotate around the rotating shafts 16. Each risk knowledge graph display screen 15 is rotatably connected to a deflection rod 17 at its back end. Each deflection rod 17 is rotatably connected to the outer wall of the fixed ring 13. When the fixed ring 13 is raised or lowered, the deflection rods 17 push the risk knowledge graph display screen 15 to rotate around the rotating shaft 16, thereby achieving synchronous adjustment of the display screen angle.

[0026] Two solar panels 18 are fixedly connected to the top of the top plate 8, and two batteries 19 are fixedly connected to the top of the top plate 8. The solar panels 18 convert solar energy into electrical energy and store it in the batteries 19 to power electrical components such as the motor 9, thereby achieving energy conservation and utilization.

[0027] In this invention, the staff pushes the device to the destination for display. The staff holds the T-shaped lever 4 and rotates it, causing the driving bevel gear 5, driven bevel gear 6, and screw 7 to rotate. This causes the lifting column 3 to slide on the hollow column 2, thereby raising and lowering the lifting column 3 and multiple risk knowledge graph display screens 15. The height of the multiple risk knowledge graph display screens 15 can be adjusted to meet different display needs. By displaying risk knowledge graph-related information on the multiple risk knowledge graph display screens 15, people can intuitively understand the information. When the display is in progress, the motor 9 is started, and the output end of the motor 9 drives the threaded rod 10 to rotate, so that the lifting block 11 and the fixing ring 13 move up and down under the limit of the limiting groove 12. This drives multiple deflection rods 17 to deflect, so that the risk knowledge graph display screen 15 rotates around the rotation axis 16 as the rotation center, realizing the synchronous adjustment of the angle of multiple risk knowledge graph display screens 15 to improve the display effect. When the display is outdoors, the solar panel 18 can convert solar energy into electrical energy and store it in the solar panel 18. The solar panel 18 then powers various electrical components, saving energy.
