Description

Technical Field

[0001] The present invention relates to the technical field of digital city information display, in particular to information display equipment for digital city operation information management. Background Art

[0002] As we all know, digital city operation information display can display the real-time traffic flow information of the main roads in the city, and intuitively present the traffic conditions of each road section on a display or projection device through different identification methods. For example, a city traffic map can be displayed on an LCD screen, using dynamic lines and color changes to indicate the flow speed of vehicles, so that people can quickly understand the current traffic situation while observing.

[0003] When displaying digital city information, especially traffic information, the existing technology has the following problems: such information is usually observed by pedestrians or drivers, so it is mostly set in outdoor environments. It is difficult to change the display content in time through traditional publicity frames, and projection or LED screen equipment is easy to affect people's observation in strong light environments, and the clarity is difficult to ensure. When displaying through LCD screens, it is necessary to pay attention to the possible moisture effect of rain and snow on the equipment, so it is inconvenient to use, and most of these devices can only be used for display, and their functionality needs to be improved;

[0004] Based on the above-mentioned problems, we found that it is difficult for the information display equipment of the existing technology to avoid the above problems at the same time. Therefore, we propose an information display device that can display information in multiple ways and improve the clarity of observation, which is aimed at digital city operation information management with stronger outdoor functionality. Summary of the invention

[0005] 1. Technical issues to be resolved

[0007] (II) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: information display equipment for digital city operation information management, including a column, a force-bearing frame is fixedly connected to the outer side of the column, six guide rails are fixedly connected to the outer side of the force-bearing frame, a display screen is movably connected to the outer side of the guide rail, a top eaves is fixedly connected to the outer side of the column, the top eaves is arranged on the top of the guide rail, a connecting tube is installed on the outer side of the column, a transparent plate is arranged on the top of the connecting tube, a laying roll is arranged on the rear side of the connecting tube, two main frames are fixedly connected to the rear side of the connecting tube, a concave display board is fixedly connected to the outer side of the main frame, a projection screen is arranged on the inner side of the concave display board, a rain eaves is fixedly connected to the top of the main frame, and a projector is installed at the bottom of the rain eaves;

[0009] The column comprises an outer column, the inner side of the outer column is movably connected with a sealing sheet, the outer side of the sealing sheet is fixedly connected with a sliding sleeve, the inner side of the sliding sleeve is slidably connected with the outer side of the outer column, the outer side of the sliding sleeve is fixedly connected with a telescopic rod, and the telescopic rod is rotatably connected with the display screen at a side close to the display screen;

[0010] A slide groove is provided on the inner side of the guide rail, and two slides are slidably connected to the inner side of the slide groove. The side of the bottom slide away from the outer column is rotatably connected to the display screen, and the inner side of the top slide is fixedly connected to the telescopic end of the telescopic rod.

[0011] A groove is provided on the inner side of the outer cylinder, a control motor is fixedly connected to the bottom of the inner side of the groove, a screw rod is fixedly connected to the output end of the control motor, the top of the screw rod is rotatably connected to the top of the inner side of the groove, a slider is threadedly connected to the outer side of the screw rod, and the outer side of the slider is fixedly connected to a sealing sheet.

[0012] By adopting the above technical scheme, by setting columns as structural supports, the eaves arranged on the top of the display screen are used to block the strong light in the top environment to avoid poor observation effect caused by too strong ambient light, and the display screen can be selected as an LED screen or a high-definition LCD screen according to cost and clarity requirements. The eaves not only block the top light, but also have the effect of blocking rain and snow. When rain and snow may contact the display screen in windy weather, the control motor on the inside of the groove drives the lead screw to rotate, and the slider threadedly connected to it will rise vertically along the inside of the groove. At this time, the telescopic rod connected to it through the sealing sheet will drag the installation position of the display screen and move upward. The top slide connected to the telescopic end of the telescopic rod will slide along the slide groove through the inner pulley, and the bottom slide will also be pulled up due to the upward movement of the display screen. Since the top of the guide rail is set to an outward-expanding arc, When the display screen moves up and approaches the roof eaves, the angle will shift, reducing the area not protected by the roof eaves. The display screen can be more effectively protected in rainy and snowy weather. When the display height and angle of the display screen need to be adjusted, it can also be achieved by controlling the forward and reverse rotation of the control motor. The connecting tube is equipped with the main frame, which can facilitate the connection and fixation of the concave display board. When the device is set up on the side of the traffic road, people can also sit and rest on the transparent board on the top of the connecting tube. The laying roll on the rear side of the connecting tube can assist in warning when it is necessary to warn vehicles and pedestrians on the road. The projector can conveniently project the projection content to be displayed or the road warning content onto the projection screen inside the concave display board for easy observation by people. The concave design of the concave display board can effectively extend the distance between the projection screen and the projector, so that the imaging can be easily adjusted.

When recycling, the inner roller can be driven to rotate by the reduction motor. Since the outer roller needs to rotate in the opposite direction during recycling, the claw surfaces of the first rubber claw ring and the second rubber claw ring contact each other. At this time, the resistance is large, so it can be subjected to force and the laying belt can be recycled.

[0033] The information display device for digital city operation information management displays data on traffic conditions, routes, weather, public transportation, etc. on a display screen. The eaves on the top of the display screen are used to block strong light in the top environment to avoid poor observation effects caused by too strong ambient light. While the eaves block the top light, they also block rain and snow. When rain and snow may contact the display screen in strong winds and other weather, the control motor on the inside of the groove drives the lead screw to rotate, and the slider threadedly connected to it will rise vertically along the inside of the groove. At this time, the telescopic rod connected to it through the sealing sheet will drag the installation position of the display screen and move upward. The top slide connected to the telescopic end of the telescopic rod will slide along the slide groove through the inner pulley, and the bottom slide The frame will also be pulled up due to the upward movement of the display screen. Since the top of the guide rail is set to be an outward-expanding arc, the display screen will be offset at an angle when it moves up and approaches the roof eaves, reducing the area not protected by the roof eaves.

By setting the press frame 26 to cooperate with the protrusion, the press frame 26 is always pulled down by the tension spring 27, and contacts the surface of the laying belt 805 through the scraping frame 28. When the laying belt 805 is recovered, impurities on its surface can be scraped off to prevent external impurities from being brought into the structure.

[0056] Working principle of this embodiment: when in use, by setting the laying roll 8, when the device needs to be used as a warning to warn people or vehicles, the laying belt 805 can be pulled forward along the recovery cap 21 on the front side of the roll shell 801, and the outer roller 803 connected thereto will rotate along the inner roller 804 while pulling forward, and the arc surfaces of the first rubber claw ring 24 and the second rubber claw ring 25 will contact each other and deform, with less resistance, so it can be pulled out smoothly, and the laying belt 805 wrapped on its surface is gradually stretched, and at this time, the pulled-out part can be laid on the road The projector 19 projects the projection content or road warning content to be displayed onto the projection screen 11 inside the concave display panel 10, and the warning content can be changed as needed. During recycling, the inner roller 804 can be driven to rotate by the reduction motor 29. Since the outer roller 803 needs to rotate in the opposite direction during recycling, the claw surfaces of the first rubber claw ring 24 and the second rubber claw ring 25 contact each other. At this time, the resistance is relatively large, and the inner roller 804 will drive the outer roller 803 to rotate and recycle the laying belt 805.
