[0022] Embodiment:

[0023] As shown in Figures 1 to 6 The present utility model provides a building device for a modular billboard, including a billboard 1 and a connecting plate 11 fixed to the back of the billboard 1. The connecting plate 11 is usually fixedly connected to the billboard 1 and is used to connect to other supporting brackets. The connecting plate 11 is movably connected with a cross fixing plate 2. The cross fixing plate 2 is movably connected at the common intersection of four billboards 1. The four billboards 1 are arranged in a "field" shape, and the cross fixing plate 2 is located at the center of the arrangement. The cross fixing plate 2 is movably connected with a connecting mechanism 3 for fixing and disassembling a single billboard 1, that is, the cross fixing plate 2 is not directly connected to the billboard 1, but the connecting mechanism 3 is connected to the billboard 1, and then the cross fixing plate 2 connects the connecting mechanism 3. A fixing handle 4 is fixedly connected to the side of the cross fixing plate 2 away from the billboard 1. The fixing handle 4 is movably connected with a locking mechanism 5 for locking and fixing the billboard 1 on a fixing bracket. The fixing bracket refers to a steel pipe bracket formed by welding on a wall or a large bracket when installing the billboard. The steel pipe is usually a square cross-section steel pipe. The locking mechanism 5 is in movable abutment with the cross fixing plate 2. The cross fixing plate 2 is arranged at the central intersection of the four billboards 1 arranged in a "field" shape, and the extension part of the cross fixing plate 2 is located at the joint of adjacent billboards 1. In use, the billboard 1 is usually placed in a supporting frame in advance, and then the billboards 1 are connected by bolts 514 and bolted to the fixing bracket.

[0024] Therefore, when using this solution, the connecting mechanism 3 is fixed on the billboard 1, and the four connecting mechanisms 3 are fixed on the cross fixing plate 2. The fixing handle 4 is fixedly connected to the cross fixing plate 2. The fixing handle 4 is placed on the fixing bracket, and one of the steel pipes on the fixing bracket is located between the fixing handle 4 and the cross fixing plate 2, so as to fix the billboard 1 on the fixing bracket.

[0025] As another embodiment, as shown in Figures 1 to 3As shown in the figure, the connection mechanism 3 of the present application includes a threaded hole 31, a folding plate 32, a fixing pin 33, a movable pin 34, a pin hole 35, a first chute 36, a telescopic rod 37 and a spring 38. The threaded hole 31 is opened at the end and the corner of the folding plate 32. The fixing pin 33 is fixedly connected to the end of the cross fixing plate 2. The cross fixing plate 2 is provided with a first chute 36 at the end far from the fixing pin 33. The movable pin 34 slides in the first chute 36. The two ends of the telescopic rod 37 are respectively fixedly connected to the movable pin 34 and the inner wall of the first chute 36. A spring 38 is sleeved outside the telescopic rod 37. The pin hole 35 is opened on the folding plate 32 and corresponds to the positions of the fixing pin 33 and the movable pin 34. For stable fixation, at least two movable pins 34 and fixing pins 33 are provided. During use, the movable pin 34 is pulled, the pin hole 35 on the folding plate 32 is inserted onto the movable pin 34, the telescopic rod 37 and the spring 38 reset the movable pin 34, and the other pin hole 35 is inserted onto the fixing pin 33. Then, the folding plate 32 and the connecting plate 11 on the advertising board 1 are fixed by a bolt 514 through the threaded hole 31. During maintenance or replacement, only the folding plate 32 connected to one of the advertising boards 1 needs to be disassembled, and it does not affect the fixation of other advertising boards 1.

[0026] The folding plate 32 is detachably connected to the connecting plate 11 through the threaded hole 31. The folding plate 32 and the cross fixing plate 2 are detachably connected through the fixing pin 33 and the movable pin 34. The arrangement of the four folding plates 32 with a common intersection forms a cross.

[0027] As another embodiment, as Figures 4 to 6As shown in the figure, several first one-way teeth 41 arranged at equal intervals are fixedly connected to one side of the fixed handle 4 of the present application close to the cross-shaped fixing plate 2. The fixed handle 4 and the cross-shaped fixing plate 2 are integrally formed or welded. The locking mechanism 5 includes a main locking block 511, a secondary locking block 512, a second one-way tooth 513, a bolt 514, a second sliding groove 515 and a slider 516. The second one-way tooth 513 is fixedly connected to one side of the main locking block 511 close to the first one-way tooth 41. The second one-way tooth 513 meshes with the first one-way tooth 41. The second sliding groove 515 is opened on one side of the main locking block 511 close to the first one-way tooth 41. There are two secondary locking blocks 512. Each secondary locking block 512 is fixedly connected with a slider 516, and the slider 516 slides in the second sliding groove 515. The secondary locking block 512 and the main locking block 511 are detachably connected by a bolt 514. In order to mesh more firmly with the first one-way tooth 41, at least two second one-way teeth 513 are provided on the main locking block 511. The bolt 514 on the secondary locking block 512 is detachable. After inserting the slider 516 into the second sliding groove 515, the secondary locking block 512 and the main locking block 511 are fixed with the bolt 514. Threaded holes 31 for inserting the bolt 514 are correspondingly opened on both the secondary locking block 512 and the main locking block 511. The depth of the second sliding groove 515 is greater than the height of the slider 516.

[0028] The locking mechanism 5 further includes a telescopic sleeve 521, a telescopic spring 522, a convex block 523 and a groove 524. One end of the telescopic sleeve 521 is fixedly connected to the side of the main locking block 511 away from the second one-way tooth 513. The other end of the telescopic sleeve 521 is fixedly connected to the convex block 523. The telescopic spring 522 is sleeved in the telescopic sleeve 521. The grooves 524 are opened on the cross-shaped fixing plate 2 at equal intervals. The convex block 523 is movably meshed with one of the grooves 524. The convex block 523 is a spherical convex block 523, and the groove 524 is a spherical groove 524. During the upward movement of the main locking block 511, the convex block 523 on the telescopic sleeve 521 is in movable contact with the groove 524. Finally, the position where the convex block 523 abuts against the groove 524 is determined by the height of the steel pipe on the fixed bracket.

[0029] During use, after hanging the fixed handle 4 on the steel pipe of the fixed bracket, insert the slider 516 on the secondary locking block 512 into the second sliding groove 515 of the main locking block 511. Since the depth of the sliding groove is greater than the height of the slider 516, there is a certain gap between the slider 516 and the second sliding groove 515, and there is a certain sliding space between the second one-way tooth 513 and the first one-way tooth 41. The main locking block 511 can slide upward on the fixed handle 4. When the main locking block 511 is in close contact with the steel pipe on the fixed bracket, the convex block 523 abuts in the corresponding groove 524. Insert the bolt 514 into the corresponding holes of the secondary locking block 512 and the main locking block 511 and tighten it.

[0030] Working principle of an erection device for a modular billboard in this application: During use, the connecting mechanism 3 is fixed to the billboard 1, and four connecting mechanisms 3 are fixed to the cross fixing plate 2. The fixing handle 4 is fixedly connected to the cross fixing plate 2. Place the fixing handle 4 on the fixing bracket, such that one of the steel pipes on the fixing bracket is located between the fixing handle 4 and the cross fixing plate 2, thereby fixing the billboard 1 to the fixing bracket. Specifically, pull the movable pin 34, insert the pin hole 35 on the folding plate 32 onto the movable pin 34. The telescopic rod 37 and the spring 38 reset the movable pin 34, and insert the other pin holes 35 onto the fixed pin 33. Then, use the bolt 514 to fix the folding plate 32 and the connecting plate 11 on the billboard 1 through the threaded hole 31. After hanging the fixing handle 4 on the steel pipe of the fixing bracket, insert the slider 516 on the secondary locking block 512 into the second chute 515 of the primary locking block 511. Since the depth of the second chute 515 is greater than the height of the slider 516, there is a certain gap between the slider 516 and the second chute 515, and there is a certain sliding space between the second one-way tooth 513 and the first one-way tooth 41. The primary locking block 511 can slide upward on the fixing handle 4. When the primary locking block 511 is in contact with the steel pipe on the fixing bracket, the convex block 523 abuts against the corresponding groove 524. Insert the bolt 514 into the corresponding holes of the secondary locking block 512 and the primary locking block 511, and tighten it. That is, the fixation of one set of modules is completed. After successively fixing them in the same manner on the fixing bracket to form the desired shape, then socket the frame. When repairing a certain billboard 1, it is only necessary to disassemble the folding plate 32 connected to one of the billboards 1, and it does not affect the fixation of other billboards 1.
