[0030] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position. Example 1

[0031] An outdoor advertising display device includes a light box 1, a movable plate 3, an advertising paper 4, a positioning roller 41, an electric push rod 5, a positioning frame 6, a universal wheel 7, a servo motor 8, a driving shaft 81, a worm 82, a worm gear 83, a fan 84, an air guide cover 85, a toothed belt assembly 9, a driven gear 91, a synchronous belt assembly 92 and a rotating shaft 93, see Figure 1-Figure 5 As shown, the middle part of the movable plate 3 is rotatably connected with a light box 1, the front and rear sides of the light box 1 are transparent plates, and the left and right sides of the light box 1 are symmetrically rotatably connected with positioning rollers 41, and advertising paper 4 is wound between the upper and lower positioning rollers 41. The movable plate 3 is symmetrically fixed with electric push rods 5, and the ends of the telescopic rods of the electric push rods 5 on the left and right sides are fixedly connected with positioning frames 6, and universal wheels 7 are arranged on the positioning frames 6. The lower rear part of the light box 1 is fixedly connected with an air guide cover 85, and the front side of the air guide cover 85 is evenly spaced and rotatably connected with four There are fans 84. When the fans 84 rotate, the fans 84 can draw the air in the light box 1 into the air guide cover 85 and discharge it to form a ventilation duct. A worm gear 83 is fixedly sleeved on the front side of the concentric axis of each fan 84. A driving shaft 81 is rotatably connected between the lower parts of the left and right sides of the light box 1. Worms 82 are fixedly sleeved on the driving shaft 81 at even intervals. The worms 82 are meshed with the corresponding worm gears 83. A servo motor 88 corresponding to the driving shaft 81 is installed on the lower part of the outer right side of the light box 1 by bolt connection. The output shaft of the servo motor 8 is connected to the driving shaft 81, and a driven gear 91 is rotatably connected to the middle part of the left side of the light box 1. A synchronous belt assembly 92 is connected between the shaft of the driven gear 91 and the left sides of the upper and lower positioning rollers 41. The synchronous belt assembly 92 consists of three pulleys and a flat belt, two of which are fixedly mounted on the left sides of the upper and lower positioning rollers 41 respectively, and the other pulley is fixedly mounted on the left side of the shaft of the driven gear 91. The flat belt is wound between the three pulleys. A rotating shaft 93 is rotatably connected to the upper and lower rear sides of the left side of the light box 1, and a toothed belt assembly 9 is connected between the rotating shaft 93 and the left side of the worm 82. The toothed belt assembly 9 consists of two pulleys and a toothed belt, one of which is fixedly mounted on the rotating shaft 93, and the other is fixedly mounted on the left side of the worm 82. The toothed belt is wound between the two pulleys, and the number of teeth of the toothed belt is sixteen. When the toothed belt assembly 9 rotates and meshes with the driven gear 91, the toothed belt assembly 9 can drive the driven gear 91 to rotate one circle.

[0032] First, the light box 1 is pushed to the display position by the universal wheel 7, and then the telescopic rod of the electric push rod 5 is shortened to drive the positioning frame 6 to move upward. The positioning frame 6 moves upward to drive the universal wheel 7 to move upward. When the universal wheel 7 moves upward to the movable plate 3, the movable plate 3 moves downward to contact the ground. Then the servo motor 8 is started to drive the driving shaft 81 to rotate. The driving shaft 81 rotates to drive the toothed belt assembly 9 to rotate. When the toothed belt assembly 9 rotates and engages with the driven gear 91, the toothed belt assembly 9 rotates to drive the driven gear 91 to rotate one circle. The driven gear 91 rotates one circle to drive the synchronous belt assembly 92 to rotate. The synchronous belt assembly 92 rotates to drive the positioning roller 41 to rotate. The positioning roller 41 rotates to drive the advertising paper 4 to rotate. The advertising paper 4 rotates to display the product information in a scrolling manner. People can view the product information on the advertising paper 4 through the transparent plate of the light box 1. The function of the plate is to see the product information more clearly. When the toothed belt assembly 9 continues to rotate and disengages from the driven gear 91, the driven gear 91 stops rotating, and the positioning roller 41 stops driving the advertising paper 4 to rotate, so that people can view the product information on the advertising paper 4, and so on and so forth. The advertising paper 4 rotates intermittently continuously, and people can view the product better. At the same time, the rotation of the drive shaft 81 also drives the worm 82 to rotate, and the rotation of the worm 82 drives the worm gear 83 to rotate, and the rotation of the worm gear 83 drives the fan 84 to rotate. The rotation of the fan 84 draws the air in the light box 1 into the air guide cover 85, and the air guide cover 85 discharges the air. At the same time, the rotation of the fan 84 also draws the outside air into the light box 1, and so on and so forth, so that the light box 1 is ventilated, and the humidity in the light box 1 is prevented from causing blurring and affecting the display of the product information on the advertising paper 4, thereby improving the display effect. When there is no need to display advertisements, the servo motor 8 is turned off, the drive shaft 81 stops driving the toothed belt assembly 9 to rotate, the advertisement paper 4 completely stops rotating, and the drive shaft 81 stops driving the worm 82 to rotate, and the fan 84 also stops rotating. The telescopic rod of the electric push rod 5 is then started to drive the positioning frame 6 to drive the universal wheel 7 to move downward and contact the ground, and the universal wheel 7 stops moving downward. As the telescopic rod of the electric push rod 5 is extended, the movable plate 3 moves upward and loses contact with the ground. The electric push rod 5 is turned off, and the light box 1 can be moved to the next position through the universal wheel 7. Example 2

[0033] On the basis of embodiment 1, it also includes a bevel gear assembly 10, a transmission rod 101, a cylindrical disc 102, a guide rod 103, a spring A 104 and a limit rod 105, see Figure 6-Figure 8As shown, a circular guide rod 103 is fixedly connected to the middle of the top of the movable plate 3, and the guide rod 103 is slidably connected to the outer bottom of the lamp box 1. A spring A104 is connected between the front and rear sides of the guide rod 103 and the outer side of the lamp box 1. A transmission rod 101 is rotatably connected to the left side of the bottom of the lamp box 1, and the upper part of the transmission rod 101 and the left side of the worm 82 are transmitted through a bevel gear assembly 10. A columnar disc 102 is fixedly connected to the bottom end of the transmission rod 101, and a column is fixedly connected to the eccentric position of the bottom of the columnar disc 102. A limit rod 105 in a circular shape is installed on the left side of the top of the movable plate 3 by bolt connection, and the inner side of the limit rod 105 contacts the column of the columnar disc 102. When the columnar disc 102 rotates, the limit rod 105 can drive the columnar disc 102 to swing along the axial position of the light box 1.

[0034] It also includes a support rod 11, a hinge rod 111, a spring B112, a positioning short column 113, a pull wire 114 and a guide tube 115, see Figure 6 and Fig. 9 As shown, the front and rear sides of the movable plate 3 are both symmetrically connected to the support rods 11 for rotation. When the support rods 11 are swung outward and unfolded, the support rods 11 can support and limit the light box 1. The inside of the movable plate 3 is symmetrically and slidingly connected with the positioning short columns 113. The positioning short columns 113 are rotatably mounted with two hinged rods 111. The outer ends of the four hinged rods 111 are respectively rotatably connected to the inner sides of the four support rods 11. Springs B112 are symmetrically connected between the outer sides of the positioning short columns 113 and the inner sides of the movable plate 3. A conduit 115 is fixedly and symmetrically penetrated inside the movable plate 3. A pull wire 114 is connected to the middle part of the inner side of the positioning frame 6. The tail end of the pull wire 114 passes through the conduit 115 and is fixedly connected to the positioning short column 113.

[0035] When the servo motor 8 is started, the driving shaft 81 rotates and drives the transmission rod 101 to rotate through the bevel gear assembly 10. The transmission rod 101 rotates and drives the column disc 102 to rotate. The column disc 102 rotates and continuously swings back and forth along the axis of the light box 1 through the limit rod 105. The back and forth swing of the column disc 102 drives the light box 1 to swing back and forth. The back and forth swing of the light box 1 causes the spring A104 to continuously expand and contract. Due to the action of the spring A104, the light box 1 can swing back and forth better. The back and forth swing of the light box 1 passes through the positioning roller 41. The intermittently rotating advertisement paper 4 is driven to swing back and forth, and the swinging of the advertisement paper 4 corresponds to the people on the left and right sides of the device, respectively, so that the people on both sides of the device can also see the product information on the advertisement paper 4 more clearly. When the servo motor 8 is turned off, the driving shaft 81 stops driving the transmission rod 101 to rotate through the bevel gear assembly 10, the transmission rod 101 stops driving the column disc 102 to rotate, the column disc 102 stops swinging back and forth through the limit rod 105, and the light box 1 also stops driving the advertisement paper 4 to swing back and forth through the positioning roller 41. In this way, it can prevent the advertisement paper 4 from being tilted relative to the people on both sides and inconvenient to view, thereby facilitating the people on both sides to view the advertisement paper 4.

[0036] When the device moves to the display position, the telescopic rod of the electric push rod 5 is shortened to drive the positioning frame 6 to move upward and reset. The positioning frame 6 moves upward to drive the universal wheel 7 to move upward and lose contact with the ground. The positioning frame 6 moves upward and also drives the pull wire 114 to move upward. The pull wire 114 moves upward and drives the positioning short column 113 to move outward through the guide tube 115. The spring B112 is compressed, and the positioning short column 113 moves outward to drive the support rod 11 to swing outward through the hinge rod 111. When the universal wheel 7 loses contact with the ground, the moving plate 3 contacts the ground, and the moving plate 3 drives the support rod 11 to contact the ground, the electric push rod 5 is closed, and the support rod 11 stops swinging outward. When the device is moved, the support rod 11 cooperates with the ground to support and limit the movable plate 3, and also supports and limits the light box 1. When the device needs to move, the telescopic rod of the electric push rod 5 is extended to drive the positioning frame 6 to move downward and reset. The positioning frame 6 resets and drives the universal wheel 7 to move downward and reset to contact the ground, and the positioning frame 6 also drives the support rod 11 to move upward and break away from the ground. At the same time, the positioning frame 6 moves upward and resets, so that the pull wire 114 moves upward and is relaxed. Due to the action of the spring B112, the positioning short column 113 moves inward and drives the pull wire 114 to move inward and reset. The positioning short column 113 resets and drives the support rod 11 to swing inward and reset through the hinge rod 111. In this way, the light box 1 can be prevented from tipping over and breaking, thereby improving the safety of the light box 1. Example 3

[0037] Based on the embodiment 1 and the embodiment 2, a mounting frame 12 and an LED lamp 13 are also included. Fig.10As shown, a mounting frame 12 is installed in the middle of the left side of the light box 1 by bolt connection, and three LED lamps 13 are fixed to the mounting frame 12. The LED lamps 13 are located on the inner side of the advertising paper 4. When the LED lamps 13 are started, the LED lamps 13 can illuminate the advertising paper 4.

[0038] Also includes a rubber pad 14, see Fig.10 As shown, a rubber pad 14 is fixedly connected to the bottom of the movable plate 3 symmetrically.

[0039] Also includes a shielding cover 15, see Fig.10 As shown, a shielding cover 15 is fixedly connected to the top of the light box 1, and when it rains, the shielding cover 15 can block the rain.

[0040] When the advertisement paper 4 is rotating for display, the LED light 13 is turned on, and the LED light 13 further illuminates the advertisement paper 4, so that people can more clearly see the product information on the advertisement paper 4. When the advertisement paper 4 completely stops rotating, the LED light 13 is turned off. In this way, people can more clearly see the product information on the advertisement paper 4, thereby further improving the display effect.

[0041] When the moving plate 3 moves downward and contacts the ground, the moving plate 3 also drives the rubber pad 14 to contact the ground, and the rubber pad 14 increases the friction with the ground, so that the moving plate 3 is placed on the ground more firmly. When the moving plate 3 moves upward to reset, the moving plate 3 drives the rubber pad 14 to move upward to reset.

[0042] When it rains, the shielding cover 15 can block the rain, thus preventing the rain from continuously dripping on the light box 1 and causing corrosion to the light box 1, thereby ensuring the integrity of the light box 1.

[0043] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
