[0020] In order to further understand the inventive content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0021] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 4As shown in the figure, an advertisement signboard convenient for assembly provided by an embodiment of the present utility model includes a fixed seat 1, an advertisement board 2, a positioning structure 3, a connection block 4 and a fixing component 5. Two support arms 101 are fixedly connected to the top of the fixed seat 1. Support blocks 102 are fixedly connected to the front surfaces of the two support arms 101. A rotating arm 103 is fixedly connected to the side of the two support blocks 102 close to each other by bolts. The left and right sides of the inner wall of the rotating arm 103 are rotatably connected to a main screw rod 6. A handle 601 is fixedly connected to the middle of the main screw rod 6. Threads with opposite directions are respectively provided on the surfaces of both ends of the main screw rod 6. Moving arms 602 are respectively threadedly connected to the surfaces of both ends of the main screw rod 6. The front surfaces of the two moving arms 602 respectively extend out of the front surface of the rotating arm 103. An advertisement board 2 is arranged on the side of the two moving arms 602 close to each other. A positioning plate 104 is fixedly connected to the top of the rotating arm 103. A connecting arm 7 is fixedly connected to the bottom of the rotating arm 103. A connecting groove 701 is provided on the back surface of the connecting arm 7. A plurality of positioning grooves 702 are respectively equidistantly provided on the left and right sides of the inner wall of the connecting groove 701. A movable arm 8 is slidably connected to the inner wall of the connecting groove 701. A positioning plate 104 is fixedly connected to the bottom of the movable arm 8. A positioning structure 3 is fixedly connected to the top of the movable arm 8. The positioning structure 3 includes a connection block 4 and a fixing component 5. The fixing component 5 is arranged inside the connection block 4.

[0023] Reference Figure 3 and Figure 4 , the outer surface of the connection block 4 is slidably connected to the inner wall of the connection groove 701. The bottom of the connection block 4 is fixedly connected to the top of the movable arm 8. Connecting rods 9 are fixedly connected to the left and right sides of the inner wall of the connection block 4.

[0024] Adopting the above scheme: By setting the connection block 4, the connection block 4 can slide in the connection groove 701 and synchronously drive the movable arm 8 to move up and down, so as to drive the positioning plate 104 at the bottom to approach and tightly adhere to the advertisement board 2, thereby cooperating with the positioning plate 104 at the top to assemble and fix it.

[0025] Reference Figure 3 and Figure 4 , the fixing component 5 includes two moving blocks 10. Both of the two moving blocks 10 are arranged on the top of the connection block 4. The bottoms of the two moving blocks 10 both extend and penetrate into the inner wall of the connection block 4. Pressing blocks 11 are fixedly connected to the tops of the two moving blocks 10. A moving rod 12 is arranged at the bottom of the two moving blocks 10.

[0026] Adopting the above scheme: By setting the moving blocks 10, when the pressing block 11 is pressed, the pressing block 11 can drive the two moving blocks 10 to move forward simultaneously, so that the two moving blocks 10 move forward, thereby driving the movement of the moving rod 12.

[0027] Reference Figure 4, the moving rod 12 is arranged inside the connecting block 4. Both ends of the moving rod 12 are fixedly connected to the sides of the two moving blocks 10 close to each other at the ends extending into the connecting block 4. Two linkage arms 13 are sleeved on the outer surface of the moving rod 12.

[0028] With the above solution: By arranging the moving rod 12, the two moving blocks 10 can drive the movement of the moving rod 12 simultaneously during the movement, so that the moving rod 12 can drive the two linkage arms 13 to move simultaneously.

[0029] Reference Figure 4 , linkage grooves 14 are respectively formed on the surfaces of the two linkage arms 13. The inner walls of the two linkage grooves 14 are respectively in contact with the outer surface of the moving rod 12. The two linkage arms 13 are arranged in a staggered manner. Limiting arms 15 are respectively fixedly connected to the bottoms of the two linkage arms 13.

[0030] With the above solution: By arranging the linkage arms 13, the moving rod 12 can simultaneously squeeze the two linkage grooves 14 during the movement to drive the two linkage arms 13 to move closer in a staggered manner, so as to drive the two limiting arms 15 to move closer respectively.

[0031] Reference Figure 4 , the tops of the two limiting arms 15 are respectively fixedly connected to the ends of the bottoms of the two linkage arms 13 away from each other. The middles of the two limiting arms 15 are respectively slidably connected to the outer surface of the connecting rod 9. A limiting spring 16 is fixedly connected to the side of the two limiting arms 15 close to each other. The limiting spring 16 is sleeved on the outer surface of the connecting rod 9. Limiting blocks 17 are respectively arranged at the bottoms of the two limiting arms 15.

[0032] With the above solution: By arranging the limiting arms 15, the two linkage arms 13 can drive the two linkage arms 13 to slide closer on the surface of the connecting rod 9 respectively, and compress the limiting spring 16. When the two limiting arms 15 slide, they drive the two limiting blocks 17 to move closer respectively.

[0033] Reference Figure 3 and Figure 4 , the two limiting blocks 17 are respectively fixedly connected to the sides of the bottoms of the two limiting arms 15 away from each other. The ends of the two limiting blocks 17 away from each other respectively extend through and out of the inner wall of the connecting block 4. The ends of the two limiting blocks 17 away from each other are respectively inserted into the inner wall of the positioning groove 702.

[0034] With the above solution: By arranging the limiting blocks 17, the two limiting blocks 17 can respectively disengage from the two positioning grooves 702 and retract into the inner wall of the connecting block 4 when moving closer, so as to release the fixed limit on the connecting block 4, so that the movable arm 8 and the connecting block 4 can slide up and down in the connecting groove 701.

[0035] Working principle of the utility model:

[0036] During use, place the bottom of the billboard 2 on the bottom positioning plate 104. Then press the pressing block 11, which drives the two moving blocks 10 to move forward, and simultaneously drives the moving rod 12 to move. During the movement of the moving rod 12, it can simultaneously squeeze the inner walls of the two linkage grooves 14, thereby driving the two linkage arms 13 to move closer in a staggered manner. When the two linkage arms 13 move, they respectively drive the two limiting arms 15 to slide closer on the surface of the connecting rod 9, and compress the limiting spring 16. When the two limiting arms 15 slide closer, they respectively drive the two limiting blocks 17 to move closer, so that the two limiting blocks 17 are respectively disengaged from the positioning grooves 702 and retracted into the inner wall of the connecting block 4, thereby releasing the fixed limit on the connecting block 4. Then, the movable arm 8 together with the connecting block 4 can be slid upward in the connecting groove 701, and the billboard 2 is driven by the bottom positioning plate 104 to move upward so that its top is in close contact with the top positioning plate 104. Then release the pressing block 11, and the limiting spring 16 pushes the two limiting arms 15 to slide away, driving the two limiting blocks 17 to be inserted into the positioning grooves 702 to fix and limit the connecting block 4 and the movable arm 8. At this time, rotate the handle 601 to drive the main screw 6 to rotate and thereby drive the two moving arms 602 to move closer to tightly press the left and right sides of the billboard 2, thereby assembling and fixing the billboard 2. The rotation angle of the rotating arm 103 can also be adjusted by bolts to adjust the angle of the billboard 2.

[0037] In summary, for the advertising signboard that is easy to assemble, through the cooperative work of the fixed seat 1, the billboard 2, the positioning structure 3, the connecting block 4, and the fixing component 5, it solves the problem that during the assembly of the advertising signboard with the support frame, the support frame usually uses a large number of screws to fixedly assemble the billboard. If the content of the billboard needs to be replaced according to the activity, the cumbersome assembly steps will reduce the flexibility of replacement.
