[0031] With the widespread development of meteorological services, many meteorological service display screens have been built outdoors; in order to facilitate more pedestrians to understand weather information, some rotatable meteorological service display screens have appeared.

[0032] The existing rotatable display screen for meteorological services comprises a screen, a rotating column and a power box. The power box is buried underground, and the power box drives the rotating column to rotate, thereby rotating the display screen arranged on the top of the rotating column.

[0033] However, damp soil can cause water to seep into the power box, thus affecting the safety of the power box.

[0034] To do this, please refer to Figure 1 The present application provides a new display device for meteorological services, including a support column 1, a connecting plate 2, a display screen 3 and a rotating mechanism 4.

[0035] Please refer to Figure 1 The bottom of the support column 1 is fixedly arranged in a preset area. The support column 1 can be a cylinder or a prism. The preset area can be a place where meteorological publicity is required, which can be referred to as the ground or foundation platform 6. The fixed arrangement can be buried or welded.

[0036] In some other examples, the preset area may also include a high-rise building, a preset frame, such as a traffic light bracket set on a road, and these brackets may also be the above-mentioned preset area. At this time, the display screen 3 may be hung on the above-mentioned traffic light bracket.

[0037] Please refer to Figure 1 The connecting plate 2 is rotatably arranged on the top of the supporting column 1. The top of the supporting column 1 can pass through the connecting plate 2.

[0038] Please refer to Figure 1, the display screen 3 is arranged on the connecting plate 2; the rotating mechanism 4 includes a first gear 41, a second gear 42, and a driving member 43, and the first gear 41 is rotatably arranged on the top of the supporting column 1.

[0039] Please refer to Figure 1 In some examples, the first gear 41 can be arranged on the end surface of the top of the support column 1, or can be arranged on the annular surface of the top of the support column 1. When the first gear 41 is arranged on the annular surface of the support column 1, the connection plate 2 and the support column 1 can be connected with a gap, thereby reducing the difficulty of installation.

[0040] Please refer to Figure 1 The second gear 42 is fixedly disposed on the connecting plate 2 , and the second gear 42 is meshed with the first gear 41 .

[0041] In some examples, the second gear 42 can be fixedly mounted on the upper wall of the connecting plate 2. In this case, a groove can be provided on the upper wall of the connecting plate 2, and the second gear 42 can be welded or bonded in the groove. In this case, the second gear 42 and the connecting plate 2 can be understood as an integral structure, so that when the second gear 42 rotates around the first gear 41, the connecting plate 2 is driven to rotate together.

[0042] In some examples, the second gear 42 may be an internal gear, and in this case, the first gear 41 may be disposed inside the second gear 42 , so that the connecting plate 2 is driven to rotate when the second gear 42 rotates.

[0043] Please refer to Figure 1 The driving member 43 is arranged on the connecting plate 2 , and the driving member 43 is transmission-connected with the second gear 42 .

[0044] In some examples, the driving member 43 is used to provide power for the rotation of the rotating frame, so the driving member 43 can be a rotating motor, or a linear motor with a connecting rod drive structure to achieve the rotation function.

[0045] In the present application, the rotating mechanism 4 is installed between the supporting column 1 and the connecting plate 2. The driving member 43 in the rotating mechanism 4 can drive the first gear 41 and the second gear 42 to rotate, drive the connecting plate 2 to rotate, and thus rotate the display screen 3. The rotating mechanism 4 is arranged between the connecting plate 2 and the supporting column 1, far from the ground, to prevent underground water and insects from entering the rotating mechanism 4 and causing damage, thereby solving the safety problem caused by being arranged underground.

[0046] Exemplarily, the connecting rod type driving structure can be rotatably connected with multiple rods. In this case, the linear motor can drive the connecting rod type driving structure within the stroke to drive the second gear 42 to rotate a certain angle, thereby achieving the effect of the second gear 42 rotating around the first gear 41.

[0047] In some examples, the driving member 43 drives the second gear 42 to rotate, and in this case, the driving member 43 and the second gear 42 may be indirectly connected.

[0048] Please refer to Figure 2 For example, a gear shaft 46 can be provided on the connecting plate 2, and the second gear 42 can be connected to the gear shaft 46 by a key. At this time, the driving shaft of the driving member 43 can be directly connected to the gear shaft 46 by a coupling, so as to achieve the effect of driving the gear shaft 46 and the second gear 42 to rotate.

[0049] Alternatively, a reducer may be provided between the driving member 43 and the second gear 42 , and the reducer may be a gear reducer or other reducers, both of which may achieve the purpose of the above-mentioned transmission connection.

[0050] Please refer to Figure 2 In some examples, in order to make the transmission between the second gear 42 and the first gear 41 accurate and stable, the transmission ratio between the second gear 42 and the first gear 41 can be a reduction ratio, that is, the diameter of the second gear 42 is greater than the diameter of the first gear 41.

[0051] In some other examples, the diameter of the second gear 42 may also be smaller than the diameter of the first gear 41, or the second gear 42 may be the same as the first gear 41, both of which can achieve the above-mentioned meshing relationship between the first gear 41 and the second gear 42, and realize the rotation of the connecting plate 2 and the display screen 3.

[0052] Please refer to Figure 2 In some examples, the rotating mechanism 4 further includes a sleeve 45 and a connecting key 44, the sleeve 45 is disposed in the first gear 41, the sleeve 45 is sleeved on the support column 1, and the connecting key 44 connects the sleeve 45 and the first gear 41. The connecting key 44 and the sleeve 45 connect the first gear 41 and the support column 1, which can make the connection between the first gear 41 and the support column 1 more stable; at the same time, this structure can also protect the first gear 41.

[0053] Please refer to Figure 2 In some examples, since keys or welding are required when installing the gears to the internal structure, directly connecting the first gear 41 and the support column 1 will cause damage to the support column 1 and reduce its service life. Therefore, a shaft sleeve 45 can be set between the first gear 41 and the support column 1 to protect the support column 1.

[0054] Please refer to Figure 2 For example, the sleeve 45 may be cylindrical or in other shapes.

[0055] Please refer to Figure 2At this time, from the inside to the outside, this part includes the support column 1, the sleeve 45, the connecting key 44 and the first gear 41. When the second gear 42 rotates, the first gear 41 is fixedly connected to the support column 1, which will cause the second gear 42 to rotate relative to the support column 1, thereby causing the connecting plate 2 to rotate around the axis of the support column 1.

[0056] Please refer to Figure 3 In some examples, the top end of the support column 1 passes through the connecting plate 2, and the first gear 41 is arranged above the connecting plate 2; the second gear 42 is arranged on the upper wall of the connecting plate 2, and the first gear 41 and the second gear 42 are meshed. Transmission is achieved by meshing the first gear 41 and the second gear 42, thereby driving the connecting plate 2 to rotate.

[0057] Please refer to Figure 2 In some examples, the rotating mechanism 4 further includes a gear shaft 46, which is disposed on the upper wall of the connecting plate 2, and the second gear 42 is mounted on the gear shaft 46. This can make the installation of the second gear 42 more convenient and the operation more stable.

[0058] In some examples, the gear shaft 46 extends in a direction perpendicular to the upper wall of the connecting plate 2 , and the axis of the gear shaft 46 may be perpendicular to the upper wall of the connecting plate 2 , so that the bottom surface of the second gear 42 is parallel to the upper wall of the connecting plate 2 .

[0059] Please refer to Figure 2 For example, a certain gap may be provided between the second gear 42 and the connecting plate 2 , so that when the second gear 42 or the gear shaft 46 is damaged, it is easy to replace it, thereby providing a certain protection effect on the connecting plate 2 .

[0060] In some other examples, the gear shaft 46 may not be provided on the connecting plate 2, and gear teeth may be integrally formed on the upper wall surface of the connecting plate 2 and meshed with the first gear 41, thereby achieving the above-mentioned meshing transmission effect of the second gear 42 and the first gear 41.

[0061] Please refer to Figure 2 In some examples, the connecting plate 2 further includes a protective cover 5, which is disposed on the connecting plate 2. The protective cover 5 has a receiving cavity, which can protect the rotating mechanism 4 from rainwater entering.

[0062] In some examples, the protective cover 5 may be integrally formed, and a gap may be provided between the protective cover 5 and the support column 1 to ensure that the protective cover 5 body is not impacted when the connecting plate 2 and the support column 1 rotate relative to each other. The size of the gap may be determined by the rotation angle of the connecting plate 2.

[0063] Exemplarily, when the rotation angle of the connecting plate 2 is 90°, that is, when the rotation angle of the screen is 90°, the area where the projection of the protective cover 5 falls on the annular surface of the support column 1 in a direction perpendicular to the axis of the support column 1 can be equal to or less than half of the area where the support column 1 is located on the annular surface.

[0064] Alternatively, when the rotation angle of the connecting plate 2 is 360°, the protective cover 5 may not be directly connected to the support column 1. In this case, the protective cover 5 may be connected to the support column 1 via a slewing bearing, or an environmental gap may be set between the protective cover 5 and the support column 1.

[0065] In some examples, the driving member 43 includes a driving member 43 body, a driving shaft and a controller. The driving member 43 body is disposed on the connecting plate 2 and disposed in the accommodating cavity of the protective cover 5. The driving shaft is connected to the driving member 43 body, and the driving shaft is connected to the gear shaft 46. The controller is disposed in the driving member 43 body. The angle of the display screen 3 can be adjusted by controlling the controller, which increases convenience.

[0066] The controller works through its internal IC control chip, and the controller is installed in the body of the driver 43 to control the driver.

[0067] In some examples, when the driving member 43 is a driving motor, the driving motor may have a built-in control chip to achieve the above-mentioned effect.

[0068] Alternatively, the controller may also be disposed outside the driving member 43 to achieve the above-mentioned control effect through electrical connection.

[0069] Please refer to Figure 1 In some examples, the weather service display device further includes a foundation platform 6, and the support column 1 is disposed on the foundation platform 6. The support column 1 is installed on the foundation, which can make the support column 1 more stable, thereby making the device more stable when working.

[0070] Please refer to Figure 1 In some examples, the connecting plate 2 also includes a bearing 21, a first plate body 22 and a second plate body 23. The first plate body 22 is rotatably disposed on the support column 1, the bearing 21 is disposed between the first plate body 22 and the support column 1, and the first plate body 22 extends in an axial direction away from the support column 1; the second plate body 23 is connected to one end of the first plate body 22 away from the support column 1, and extends along the axial direction of the column; the display screen 3 is connected to the second plate body 23.

[0071] The first plate 22 is used to connect the rotating mechanism 4 and the supporting column 1, and the second plate 23 is used to set the display screen 3. On the one hand, the position of the display screen 3 can be adjusted by adjusting the length of the first plate 22. On the other hand, the display screen 3 is installed on the surface of the second plate 23. Compared with being directly installed on the first plate 22, the installation contact surface of the display screen 3 can be increased, thereby improving the stability of the display screen 3.

[0072] Please refer to Figure 2 In some examples, the bearing 21 may be the same type of bearing 21 as the first bearing 21 , such as a deep groove ball bearing 21 .

[0073] The size of the bearing 21 may be the same as that of the first bearing 21. The bearing 21 may be located above the first bearing 21 or below the first bearing 21.

[0074] In some examples, the first plate 22 is used to install the rotating mechanism 4 and connect the supporting column 1 , and the second plate 23 is only used to fix the display screen 3 .

[0075] In some examples, the angle between the plate surface of the first plate body 22 and the plate surface of the second plate body 23 may be between 30° and 150°, such as 30°, 90°, 150°, and preferably 90°.

[0076] In some examples, the first plate body 22 and the second plate body 23 can be integrally formed or bent, and both can achieve the above-mentioned connection effect.

[0077] Alternatively, the first plate body 22 and the second plate body 23 may be connected by welding, clamping or bolting, so that when the display screen 3 rotates, pedestrians can normally view the weather service information.

[0078] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0079] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto.
