DETAILED DESCRIPTION

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0027] See also Figure 1-8 The utility model provides a technical solution: a retractable billboard rain shield device, comprising a frame 10, an electronic billboard 11 is installed with internal bolts of the frame 10, a rain shield 14 is fixed with bolts on the upper end of the frame 10, two rotating shafts 15 are respectively rotatably provided on both sides of the interior of the rain shield 14, and two bundles of waterproof cloth 16 are respectively wound around the outer sides of the two rotating shafts 15, two fixed plates 13 are respectively welded and fixed on both sides of the frame 10, four slide grooves 22 are respectively provided on the two fixed plates 13, a moving block 17 is vertically slidably provided between every two slide grooves 22, each moving block 17 is fixedly connected to the lower end of the waterproof cloth 16, four frame bodies 18 are respectively bolted to the outer sides of the two fixed plates 13, two moving plates 19 are respectively vertically slidably provided inside every two frame bodies 18, and every two moving plates 19 are respectively fixedly connected to the two ends of the moving block 17, a motor 20 is bolted to the lower side of the interior of each frame body 18, a screw rod 21 is provided at the output end of each motor 20, and the outer side of each screw rod 21 is in threaded contact with the moving plate 19.
[0028] Further, such as Figure 6 As shown, two first folded cloths 23 are connected between the lower sides of the two ends of each moving block 17 and the lower sides of the two slide grooves 22, and two second folded cloths 31 are connected between the upper sides of the two ends of each moving block 17 and the upper sides of the two slide grooves 22.
[0029] Further, such as Figure 7-8 As shown, four discs 25 are welded and fixed on both sides of the interior of the rain shield 14. Every two discs 25 are respectively located on the outer sides of the two ends of the rotating shaft 15. Each disc 25 is in sliding contact with the outer side of the rotating shaft 15. Two annular parts 26 are welded and fixed on the outer sides of the two ends of the rotating shaft 15. The two annular parts 26 are respectively in annular sliding contact with the insides of the two discs 25. Two torsion springs 27 are connected between the outer sides of the two annular parts 26 and the inner sides of the two discs 25.
[0030] Further, such as Figure 1-3 As shown, the vertical cross-section of the rain shield 14 is a triangular structure, the width of the lower horizontal cross-section of the rain shield 14 is greater than the width of the frame 10 , and the width of each fixing plate 13 is greater than the width of the frame 10 .
[0031] Further, such as Figure 1-4 As shown, two rain shields 29 are respectively provided on both sides of the interior of the rain shield 14 for inclined sliding, and two turntables 28 are respectively sleeved on the outer sides of both ends of each rotating shaft 15. The outer sides of each two turntables 28 are in friction contact with the lower side of the same rain shield 29, and the inclined lower end of each rain shield 29 extends to the bottom of the rain shield 14.
[0032] Further, such as Figure 1-4 As shown, a fixing block 24 is fixedly disposed on the inner upper side of the rain shield 14 , and two springs 30 are connected between the inclined upper ends of the two rain shield plates 29 and the two sides of the fixing block 24 .
[0033] Further, such as Figure 1 As shown, two support blocks 12 are fixedly provided at intervals at the lower end of the frame 10 .
[0034] During use, when encountering heavy rain and strong wind, most of the rainwater moves directly downward, and a small part of the rainwater moves obliquely downward due to the strong wind; at this time, the four motors 20 are started to drive the four screw rods 21 to rotate respectively, and the four screw rods 21 rotate clockwise to drive the four moving plates 19 to move respectively, and the four moving plates 19 slide vertically downward in the four frames 18 respectively, thereby driving the two moving blocks 17 to move downward; the moving blocks 17 move downward to drive the waterproof cloth 16 wrapped around the outer side of the rotating shaft 15 to move downward continuously, and the movement of the waterproof cloth 16 drives the rotating The shaft 15 rotates, and the rotation of the rotating shaft 15 drives the two annular members 26 to rotate in the two discs 25 respectively. The rotation of the annular member 26 causes the torsion spring 27 to deform and generate elastic force; at the same time, the rotation of the rotating shaft 15 drives the two rotating disks 28 to rotate, and the two rotating disks 28 rotate and contact with the same rain shield 29 through the two rotating disks 28, so that the rain shield 29 tilts and moves downward; the rain shield 29 tilts and moves downward to stretch and deform the spring 30, so that the rain shield cover 14 cooperates with the two rain shields 29 to move downward to block and guide most of the rainwater. Among them, when the rain shield 29 slides downward at an angle so that the spring 30 is stretched to the maximum extent, the turntable 28 rotates and frictionally contacts the rain shield 29, but the rain shield 29 is stretched by the spring 30, so that the rain shield 29 stops moving. At this time, the friction force between the turntable 28 and the rain shield 29 is less than the elastic force of the spring 30 on the rain shield 29, and the stopping of the movement of the rain shield 29 does not affect the rotation of the turntable 28; when the rain shield 29 slides downward at an angle so that the spring 30 is stretched to the maximum extent and the turntable 28 stops rotating, the two turntables 28 are in frictional contact with the lower side of the rain shield 29. At this time, the friction force between the turntable 28 and the rain shield 29 is equal to the elastic force of the spring 30 on the rain shield 29, so that the rain shield 29 is in a state of stopping moving.
[0035] When the weather clears up, the four motors 20 start and respectively drive the four screw rods 21 to rotate. The four screw rods 21 rotate counterclockwise and respectively drive the four movable plates 19 to move. The four movable plates 19 slide vertically upward in the four frames 18 respectively, thereby driving the two movable blocks 17 to move upward; the movable blocks 17 move upward and cooperate with the torsional elastic force of the two torsion springs 27 on both ends of the rotating shaft 15, so that the rotating shaft 15 rotates and resets, so that the waterproof cloth 16 can be rewound around the outside of the rotating shaft 15, which is conducive to quickly displaying the electronic billboard 11. At the same time, the rotation and reset of the rotating shaft 15 drives the two rotating disks 28 to rotate. The rotation of the two rotating disks 28 acts on the rain shield 29 through the friction between the rotating disk 28 and the rain shield 29 and the elastic force of the spring 30, so that the rain shield 29 is tilted and moved upward to reset, thereby squeezing and deforming the spring 30 through the rain shield 29 to generate an elastic force; when the rain shield 29 moves to the reset position, the rain shield 29 is subjected to the elastic force of the spring 30, so that the rain shield 29 is in a state of stopping moving. At this time, the friction force between the rotating disk 28 and the rain shield 29 is less than the elastic force of the spring 30 on the rain shield 29, and the stopped state of the rain shield 29 does not affect the rotation of the rotating disk 28.
[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the appended claims and their equivalents.
