[0002] With the continuous improvement of the requirements for surveying and mapping data processing and the continuous increase in computer functions, the collected basic construction data of surveying and mapping projects are of various specifications. It is necessary to integrate the collected data, import it into ArcGIS, and then use the computer to operate it, and finally display the results of the data organization by using a display device.

[0003] Most of the existing statistical data display devices display the statistical data by controlling the device to transmit it to the display screen. However, the existing display devices have a relatively simple structure. During use, they are exposed to the outside for a long time. During the non-display period, they are still affected by external human factors or impurities and dust in the air. They lack self-protection functions, thus affecting the service life of the display screen.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a retractable display device. Utility Model Content

[0020] In the embodiment of the utility model, a maintenance opening 14 is provided on the side wall of the display box 10 opposite to the display opening 13, and a baffle is hinged at the maintenance opening 14, so that the display screen 11, the control host, the storage mechanism 12 and other structural components inside the display box 10 can be easily repaired and replaced through the maintenance opening 14, that is, the convenience of operation of the device is improved;

[0021] The foldable baffle plate 31 may also be replaced by a baffle cloth, a baffle cover or the like, and in combination with the positioning structure, the display opening 13 can be freely blocked, sealed or rolled up.

[0022] In one embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6The storage mechanism 12 includes two extension rods 22 fixedly installed on both sides of the back of the display screen 11. The bottom end of the extension rod 22 away from the display port 13 is rotatably connected to a pulley 23. The bottom of the pulley 23 corresponds to the display screen box 10. An inclined storage slide 21 with an L-shaped structure is installed inside. The pulley 23 rolls along the inclined straight section of the storage slide 21. The end of the extension rod 22 close to the display port 13 is rotatably connected to a swing rod I 24. The end of the swing rod I 24 is rotatably connected to an output shaft 28. One side of the output shaft 28 is connected to a servo motor II 20 fixed on the inner wall of the display screen box 10. A swing rod II 25 is connected to one side of the swing rod I 24. The end of the swing rod II 25 is rotatably connected to a swing spring connecting rod 26. The swing spring connecting rod 26 is connected to a spring 27 on the side facing the bottom of the display screen box 10. The bottom end of the spring 27 is connected to a fixed spring connecting rod 30 whose end is fixed on the inner wall of the display screen box 10. The servo motor II 20 is provided The servo motor 20 is started to drive the output shaft 28 to rotate, and then the sway bar Ⅰ 24 is connected with the sway bar Ⅱ 25, and the sway bar Ⅰ 24 drives the extension rod 22 at its top to swing toward the display opening 13, and the sway bar Ⅱ 25 swings upward to control the spring 27 to stretch. When the left extension rod 22 swings outward, the pulley 23 at the bottom of the right extension rod 22 is driven to roll along the inclined straight section of the storage slide 21, thereby transferring the display screen 11 toward the display opening 13, until the display screen 11 is vertically transferred to the display opening 13 for outward display use, and then when the display screen 11 is stored, the servo motor 20 is controlled to rotate in the opposite direction, and the above process is controlled to run in the opposite direction until the display screen 11 is swung to the top of the display screen box 10 and is at a horizontal angle, thereby realizing the automatic storage and display use of the display screen 11, that is, increasing the protection of the display screen 11 and improving the service life of the display screen 11.

[0023] As a preferred embodiment of the present utility model, refer to 5, Figure 7The cleaning assembly includes a cleaning shaft 18 that moves horizontally and cyclically along the top of the display screen box 10. One end of the cleaning shaft 18 is connected to a rotating rod. The end of the rotating rod is rotatably connected to a nut 17. The nut 17 has a rotating hole 29 on the side facing the rotating rod. The rotating rod is rotatably connected in the rotating hole 29. The middle part of the nut 17 is threadedly connected to a lead screw 16 that rotates inside the display screen box 10. One end of the lead screw 16 is rotatably set in the inner wall of the display screen box 10, and the other end is connected to a servo motor 15 fixed on the inner wall of the display screen box 10. The nut 17 is provided with a screw 16 that rotates inside the display screen box 10. There is a guide device for limiting its self-rotation, and the servo motor 15 is started to drive the lead screw 16 to rotate, thereby driving the nut 17 to move back and forth along the lead screw 16, and then the rotating rod is connected with the rotating hole 29 by rotation, thereby driving the cleaning shaft 18 to move back and forth along the upper side of the display screen 11. A brush 19 is arranged on the outer side of the cleaning shaft 18, and the end of the brush 19 on the lower side contacts the top of the display screen 11 that is swung to a horizontal angle, that is, during the movement of the cleaning shaft 18, the brush 19 is controlled to rotate to roll and clean the front of the display screen 11 for dust removal;

[0024] Specifically, the length of the cleaning shaft 18 is greater than the width of the display screen 11 , ensuring that the front of the display screen 11 is fully cleaned and dusted.

[0025] The utility model provides a retractable display device in the above embodiment. Before use, the ArcGIS data to be displayed is counted and transmitted to the display screen 11 through the control host. Then, according to the display needs, the servo motor 20 is started to rotate to drive the output shaft 28 to rotate. Then, under the connection between the swing rod Ⅰ 24 and the swing rod Ⅱ 25, the swing rod Ⅰ 24 drives the extension rod 22 at its top to swing toward the display port 13. The swing rod Ⅱ 25 swings upward to control the spring 27 to stretch. When the left extension rod 22 swings outward, it drives the pulley 23 at the bottom of the right extension rod 22 to move along the storage slideway. The inclined straight line segment 21 rolls, thereby transferring the display screen 11 toward the display opening 13, until the display screen 11 is vertically transferred to the display opening 13, and ArcGIS data is displayed outwardly. Then, when the display screen 11 is stored, the servo motor 20 is controlled to rotate in the reverse direction, and the above process is controlled to run in the reverse direction, until the display screen 11 is swung to the top of the display screen box 10 and is at a horizontal angle, and then the servo motor 15 is started to drive the lead screw 16 to rotate, and then the nut 17 is controlled to drive the brush 19 on the cleaning shaft 18 to rotate and clean the front of the display screen 11 to remove dust.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
