Description

Technical Field

[0001] This utility model relates to the field of radar multifunction display technology, specifically a radar multifunction display that is easy to adjust the viewing angle. Background Technology

[0002] A radar display is a terminal device that displays radar information in real time. As a key interface for human-computer interaction, it first appeared during World War I. The main types include Type A, Type J, and Type P planar position displays, and Type B rectangular coordinate displays. This device uses cathode ray tubes to achieve spot deflection modulation or brightness modulation. The afterglow time of the fluorescent material ranges from less than 1 microsecond to more than 1 minute. Shipboard displays must meet the effective diameter standard corresponding to tonnage (e.g., ≥250mm for ships of 1600 gross tons and above). Traditional radar image display is divided into primary display (raw video or signal-processed video) and secondary display (computer-processed data or integrated video). The P-type display uses radial circular scanning display, achieved through electromagnetic deflection or electrostatic deflection oscilloscope tubes, and can overlay map backgrounds, distance / angle markers, and other auxiliary observation methods.

[0003] Currently, some existing radar multifunction displays are installed on the top of the ship or the inner wall of the cabin using brackets or booms. After installation, the angle is relatively fixed, and the viewing angle of the display cannot be adjusted in real time according to actual use needs, which is relatively inconvenient. To address this issue, we propose a radar multifunction display with an adjustable viewing angle to solve or improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a radar multi-function display that facilitates viewing angle adjustment, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A radar multifunction display with adjustable viewing angle includes a fixed base plate, a support rod fixed to the top of the fixed base plate, a first rotating shaft fixed to the top of the support rod, a second rotating ring rotatably mounted inside the first rotating shaft via a bearing, a second rotating plate fixed to the surface of the second rotating ring, the first rotating ring rotatably mounted inside the first rotating shaft via a bearing, and the first rotating plate fixed to the surface of the first rotating ring.

[0007] A support plate is fixed to the surface of the first rotating shaft plate, and the support plate is also fixed to the surface of the second rotating shaft plate. The positions of the support plate fixed to the surface of the second rotating shaft plate and the first rotating shaft plate are symmetrical. A limit toothed ring is fixed to the surface of the first rotating ring. A central connecting post is inserted inside the first rotating shaft component. The central connecting post is located inside the first rotating shaft component and is slidably connected to the first rotating shaft component.

[0008] As a preferred embodiment of this utility model, a second limiting plate is fixed at the bottom of the central connecting column, the second limiting plate is located inside the first rotating shaft and is slidably connected to the first rotating shaft, and a second connecting crossbar is fixed on the surface of the central connecting column.

[0009] As a preferred embodiment of this utility model, a connecting block is fixed to the surface of the second connecting crossbar, and two sets of the connecting blocks are symmetrically fixed to the surface of the second connecting crossbar. Limiting teeth are fixed to the surface of the connecting blocks, and several sets of limiting teeth are equidistantly arranged on the surface of one set of connecting blocks.

[0010] As a preferred embodiment of this utility model, the limiting fixing tooth is located on one side of the limiting tooth ring and meshes with the limiting tooth ring, a first connecting rod is inserted inside the central connecting column, the first connecting rod is rotatably connected to the central connecting column through a bearing, and a first limiting plate is fixed at the bottom of the first connecting rod.

[0012] As a preferred embodiment of this utility model, a spring is sleeved on the surface of the central connecting column, one end of the spring is fixed to the inner surface of the first rotating shaft, and the other end of the spring is fixed to the surface of the second limiting plate.

[0013] As a preferred embodiment of this utility model, a second rotating shaft is fixed between the two sets of symmetrical support plates, and a radar multi-function display is fixed to one side of the second rotating shaft via a support member.

[0014] As a preferred embodiment of this utility model, the surface of the inner tooth block of the limiting tooth ring is provided with an inclined surface at a certain angle, and the surface of the limiting fixing tooth is also provided with an inclined surface at a certain angle corresponding to the inner tooth block of the limiting tooth ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by setting a limiting tooth ring and a limiting fixing tooth, when it is necessary to adjust the viewing angle of the radar multi-function display upward, the radar multi-function display can be directly pushed, causing the radar multi-function display to drive the first rotating shaft plate and the second rotating shaft plate to rotate through the second rotating shaft and the support plate. After adjustment, the position of the first rotating ring and the first rotating shaft plate can be restricted by the limiting tooth ring and the limiting fixing tooth.

[0017] 2. In this utility model, by setting a first connecting crossbar, when a person pulls the first connecting crossbar with the handle, the bottom of the first connecting crossbar can be disengaged from the inside of the second rotating shaft plate. At this time, the handle and the first connecting crossbar can be rotated so that the first connecting crossbar is no longer aligned with the groove on the surface of the second rotating shaft plate. At this time, the person does not need to continuously pull the handle to keep the limiting fixing teeth and the limiting tooth ring in a disengaged state, which makes it convenient for the person to adjust the viewing angle of the radar multi-function display and improves the convenience of adjustment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-5 This utility model provides a technical solution:

[0026] A radar multi-function display with adjustable viewing angle includes a fixed base plate 1, a support rod 2 fixed to the top of the fixed base plate 1, a first rotating shaft 3 fixed to the top of the support rod 2, a second rotating ring 17 rotatably mounted inside the first rotating shaft 3 via bearings, a second rotating plate 5 fixed to the surface of the second rotating ring 17, the rotation of the second rotating plate 5 causing the fixed second rotating ring 17 to rotate, a first rotating ring 12 rotatably mounted inside the first rotating shaft 3 via bearings, a first rotating plate 4 fixed to the surface of the first rotating ring 12, the rotation of the first rotating plate 4 causing the fixed first rotating ring 12 to rotate, a support plate 7 fixed to the surface of the first rotating plate 4, and the support plate 7 also fixed to the surface of the second rotating plate 5. When the support plate 7 rotates... This will cause the fixed support plate 7 or the second rotating shaft plate 5 to rotate. The second rotating shaft plate 5 and the support plate 7 fixed on the surface of the first rotating shaft plate 4 are symmetrical to each other. The surface of the first rotating ring 12 is fixed with a limiting toothed ring 15. When the first rotating ring 12 rotates, it will cause the fixed limiting toothed ring 15 to rotate. A central connecting post 19 is inserted inside the first rotating shaft 3. The central connecting post 19 is located inside the first rotating shaft 3 and is slidably connected to the first rotating shaft 3. A second limiting plate 20 is fixed at the bottom of the central connecting post 19. The second limiting plate 20 is located inside the first rotating shaft 3 and is slidably connected to the first rotating shaft 3. When the central connecting post 19 moves, it will cause the fixed second limiting plate 20 to move. The second limiting plate 20 can adjust the position of the central connecting post 19. To prevent the central connecting column 19 from detaching from the interior of the first rotating shaft 3, a second connecting crossbar 14 is fixed to the surface of the central connecting column 19. When the central connecting column 19 moves, it will drive the fixed second connecting crossbar 14 to move. A connecting block 13 is fixed to the surface of the second connecting crossbar 14. When the second connecting crossbar 14 moves, it will drive the fixed connecting block 13 to move. Two sets of connecting blocks 13 are symmetrically fixed to the surface of the second connecting crossbar 14. Limiting teeth 16 are fixed to the surface of the connecting blocks 13. Several sets of limiting teeth 16 are equidistantly arranged on the surface of one set of connecting blocks 13. When the connecting blocks 13 move, they will drive the fixed limiting teeth 16 to move. The limiting teeth 16 are located on one side of the limiting tooth ring 15 and mesh with the limiting tooth ring 15. When the connecting block 13 moves, it drives the limiting fixing tooth 16 to move, causing the limiting fixing tooth 16 to disengage from the limiting tooth ring 15. When the limiting fixing tooth 16 is engaged with the limiting tooth ring 15, the limiting fixing tooth 16 can restrict the position of the first rotating ring 12 through the connecting block 13 and the limiting tooth ring 15, thereby restricting the position of the first rotating ring 12 on the first rotating shaft plate 4. A first connecting rod 10 is inserted inside the central connecting column 19. The first connecting rod 10 is rotatably connected to the central connecting column 19 through a bearing. A first limiting plate 18 is fixed to the bottom of the first connecting rod 10. The first limiting plate 18 can restrict the position of the first connecting rod 10 and prevent the first connecting rod 10 from disengaging from the interior of the central connecting column 19.When the first connecting rod 10 moves, it drives the central connecting column 19, which is rotatably connected, to move. A first connecting crossbar 6 is fixed to the surface of the first connecting rod 10. One bottom side of the first connecting crossbar 6 is fitted into the interior of the second rotating shaft plate 5. When the first connecting crossbar 6 moves, it drives the fixed first connecting rod 10 to move. A handle 11 is rotatably mounted on the surface of the first connecting crossbar 6 via a rotating shaft. When the handle 11 moves or rotates, it drives the first connecting crossbar 6, which is rotatably connected, to move or rotate. A spring 21 is sleeved on the surface of the central connecting column 19. One end of the spring 21 is fixed to the inner surface of the first rotating shaft 3, and the other end of the spring 21 is fixed to the surface of the second limiting plate 20. When the central connecting column 19 moves, causing the second limiting plate 20 to move, the second limiting plate 20 will compress the spring 21, causing the spring 21 to deform. When there is no external interference, the spring 21 will push the second limiting plate 20 to move, causing the second limiting plate 20 to drive the central connecting column 19 to move. At the same time, the spring 21 can continuously push the second limiting plate 20, causing the second limiting plate 20 to pass through the central connecting column 19 and the second connecting crossbar. 14 and connecting block 13 push the limiting fixing tooth 16, so that the limiting fixing tooth 16 is always engaged with the limiting tooth ring 15. A second rotating shaft 8 is fixed between the two sets of symmetrical support plates 7. The internal and external structure, usage and working principle of the second rotating shaft 8 are the same as those of the first rotating shaft 3, only the installation direction is different, and it will not be described again here. A radar multi-function display 9 is fixed to one side of the second rotating shaft 8 through a support. When the radar multi-function display 9 moves, it will drive the second rotating shaft 8 to move, thereby making the second rotating shaft 8 move. The second rotating shaft 8 drives the support plate 7 to move. The surface of the internal tooth block of the limiting gear ring 15 is provided with an inclined surface at a certain angle. The surface of the limiting fixing tooth 16 is also provided with an inclined surface at a certain angle corresponding to the internal tooth block of the limiting gear ring 15. When the support plate 7 rotates to one side and drives the first rotating shaft plate 4 and the first rotating ring 12 to rotate to one side, the inclined surface of the limiting gear ring 15 will press against the inclined surface of the limiting fixing tooth 16, thereby pushing the limiting fixing tooth 16 to move and causing the limiting fixing tooth 16 to disengage from the meshing connection with the limiting gear ring 15.

[0027] The working process of this utility model is as follows: When it is necessary to adjust the viewing angle of the radar multifunction display 9 upward, the radar multifunction display 9 is directly pushed, causing it to rotate through the second rotating shaft 8 and the support plate 7, thereby driving the first rotating shaft plate 4 and the second rotating shaft plate 5 to rotate. After the adjustment is completed, the spring 21 will push the second limiting plate 20, causing the second limiting plate 20 to push the limiting fixing tooth 16 to move through the central connecting column 19, the second connecting crossbar 14 and the connecting block 13, so that the limiting fixing tooth 16 re-engages with the limiting tooth ring 15, thereby enabling the first rotating ring to rotate through the limiting tooth ring 15 and the limiting fixing tooth 16. The position of the first rotating shaft plate 4 is restricted by the handle 12, which allows for upward adjustment of the viewing angle of the radar multifunction display 9. When it is necessary to adjust the viewing angle of the radar multifunction display 9 downward, pulling the handle 11 will cause the handle 11 to move the limiting fixing tooth 16 through the first connecting crossbar 6, the first connecting rod 10, the central connecting column 19, the second connecting crossbar 14, and the connecting block 13. This will disengage the limiting fixing tooth 16 from the limiting tooth ring 15, allowing the radar multifunction display 9 to be pushed to adjust its viewing angle downward. After adjustment, the handle 11 can be released. 1. Spring 21 pushes the second limiting plate 20, causing the second limiting plate 20 to move the limiting fixing tooth 16 through the central connecting column 19, the second connecting crossbar 14, and the connecting block 13. This allows the limiting fixing tooth 16 to re-engage with the limiting tooth ring 15, thereby restricting the position of the first rotating ring 12 and the first rotating shaft plate 4 through the limiting tooth ring 15 and the limiting fixing tooth 16. This completes the downward adjustment of the viewing angle of the radar multi-function display 9. Similarly, the viewing angle of the radar multi-function display 9 can be adjusted left and right through the second rotating shaft 8, allowing the viewing angle of the display to be adjusted in real time according to actual usage needs. The angle can be adjusted, making it relatively convenient to use. When adjusting the angle of the radar multifunction display 9, the bottom of the first connecting crossbar 6 can be disengaged from the inside of the second rotating shaft plate 5 by pulling the first connecting crossbar 6 through the handle 11. At this time, the handle 11 and the first connecting crossbar 6 can be rotated so that the first connecting crossbar 6 is no longer aligned with the groove on the surface of the second rotating shaft plate 5. At this time, the personnel do not need to continuously pull the handle 11 to keep the limiting fixing tooth 16 and the limiting tooth ring 15 in a disengaged state, which makes it convenient for personnel to adjust the viewing angle of the radar multifunction display 9 and improves the convenience of adjustment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
