[0018] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0019] This application discloses an advertising frame that facilitates content replacement, including a box body 1. A transparent cover is rotatably connected to one side of the opening of the box body 1 via a hinge. A rotating mechanism is provided at the top of the box body 1. A roller 4 is detachably connected to the rotating end of the rotating mechanism. A canvas 5 is fixedly connected to the surface of the roller 4. A connecting roller 13 is fixedly connected to the bottom of the canvas 5. An insert 12 is fixedly connected to the middle of the connecting roller 13. A limiting groove 14 is formed on the surface of the insert 12. A groove 6 is formed in the middle of the bottom surface of the box body 1. The front side of the groove 6 is set to be open. A limiting block 3 that matches the limiting groove 14 is fixedly connected to the bottom of the cover. When the cover is closed on the opening of the box body 1, the limiting block 3 is inserted into the limiting groove 14.

[0020] In this embodiment, the rotating mechanism is detachably connected to the roller 4 to facilitate the assembly and disassembly of the canvas 5. When the roller 4 is connected to the rotating end of the rotating mechanism, the rotating mechanism can drive the roller 4 to rotate forward or backward, thereby unwinding or rewinding the canvas 5 for easy use. In addition, by setting a limiting block 3 to cooperate with the limiting groove 14, when installing the canvas 5, the insert block 12 can be inserted into the groove 6. When the cover is closed, the limiting block 3 can be inserted into the limiting groove 14, which can position the insert block 12 and the connecting roller 13, thus stabilizing the canvas 5.

[0021] Furthermore, the rotating mechanism includes a groove 9 opened on one side of the housing 1, a motor 7 is fixedly installed at the top of the groove 9, and connecting seats 10 are rotatably connected to both sides of the top of the housing 1. The output shaft of the motor 7 passes through the inner wall of the housing 1 and is fixedly connected to the connecting seat 10 on the same side.

[0022] Furthermore, both sides of the roller 4 are provided with sliding grooves 16, and connecting blocks 17 are slidably connected inside the sliding grooves 16. Connecting slots 11 adapted to the connecting blocks 17 are provided on the surface of the connecting seat 10. Both the connecting blocks 17 and the connecting slots 11 are rectangular. A spring 15 is fixedly connected between the inner surface of the sliding groove 16 and the connecting block 17.

[0023] Furthermore, when the spring 15 is not subjected to external force, the distance between the far ends of the two sets of connecting blocks 17 is greater than the distance between the two sets of connecting seats 10. When the two sets of connecting blocks 17 are located inside the slide groove 16, the distance between the far ends of the two sets of connecting blocks 17 is less than the distance between the two sets of connecting seats 10.

[0024] In this embodiment, when installing the roller 4, the two sets of connecting blocks 17 are moved into the groove 16, at which time the spring 15 is compressed. Then the roller 4 is placed between the two sets of connecting seats 10, and the connecting blocks 17 are aligned with the connecting groove 11. Then the connecting blocks 17 are released, the compressed spring 15 extends, and the connecting blocks 17 are moved into the connecting groove 11, thus completing the installation of the roller 4. Then the rotating mechanism is used to drive the roller 4 to rotate, unwind the canvas 5, and insert the insert block 12 into the groove 6. The cover is closed, and the limiting block 3 is inserted into the limiting groove 14, thus completing the installation of the canvas 5. When disassembling, the cover is opened, the limiting block 3 is moved out of the limiting groove 14, the rotating mechanism is used to drive the roller 4 to rotate, and the canvas 5 is wound up. Then the two sets of connecting blocks 17 are pressed to move the connecting blocks 17 out of the connecting groove 11, thus inserting the canvas 5.

[0025] Furthermore, the cover includes a frame plate 2 and a glass plate 8. The frame plate 2 is rotatably connected to the box body 1 by a hinge. The glass plate 8 is fixedly installed inside the frame plate 2, and the limiting block 3 is fixedly installed at the bottom of the frame plate 2.

[0026] In this embodiment, when the cover is closed on the opening of the box 1, the frame plate 2 can block the rotating mechanism, the roller 4 and the connecting roller 13, etc., and the unfolded part of the canvas 5 can be viewed through the glass plate 8.
