[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 This utility model provides a technical solution for a movable advertising curtain:

[0026] A movable advertising curtain includes a roller 1, a roller blind 2 fixedly connected to the surface of the roller 1, and an advertising curtain 3 detachably connected to the bottom of the roller blind 2. The advertising curtain 3 and the roller blind 2 are connected by adhesive 15. The curtain also includes a housing 4, with an end cap 16 fixedly connected to the inner wall of the housing 4. Both ends of the roller 1 are rotatably connected to the inner wall of the housing 4. The bottom of the roller blind 2 extends downward to the outside of the housing 4. A clamping member 5 is disposed inside the housing 4 and closely attached to the roller 1. An elastic member 6 is fixedly connected to the top of the housing 4, and the bottom of the elastic member 6 extends into the inside of the housing 4 and is connected to the clamping member 5.

[0027] Specifically, by setting up the elastic component 6 and the pressing component 5, when the roller 1 rolls up the roller blind 2, the pressing component 5 continuously presses against the surface of the roller blind 2 under the action of the elastic component 6, forming radial pressure. When the roller blind 2 becomes momentarily loose, the elastic component 6 can push the pressing component 5 to fill the loose gap, forcing the roller blind 2 to fit tightly against the roller 1, preventing loose winding, so that the movable advertising curtain has the effect of preventing the roller blind from loosening.

[0028] The elastic component 6 includes a housing 601 fixedly connected to the top of the housing 4. A top plate 602 is connected to the inner wall of the housing 601. A spring 603 is fixedly connected to the bottom of the top plate 602. A sliding plate 604 is fixedly connected to the bottom end of the spring 603. The sliding plate 604 is slidably connected to the inner wall of the housing 601. A connecting post 605 is fixedly connected to the bottom of the sliding plate 604. The bottom end of the connecting post 605 extends into the interior of the housing 4 and is connected to the clamping member 5. Dynamic pressure is applied to the sliding plate 604 by the spring 603, thereby generating dynamic pressure on the connecting post 605, and in turn, dynamic pressure on the clamping member 5.

[0029] The top of the top plate 602 has a sliding hole, and a sliding rod 606 is slidably connected to the inner wall of the sliding hole. The sliding rod 606 passes through the spring 603, and the bottom end of the sliding rod 606 is fixedly connected to the sliding plate 604. By setting the sliding rod 606, the stability of the spring 603 when compressed is improved.

[0030] The top of the outer casing 601 has a threaded hole, and the inner wall of the threaded hole is threaded with a screw 8 with a knob 7. The bottom end of the screw 8 is fixedly connected to a connecting block 9. The bottom of the connecting block 9 is rotatably connected to the top of the top plate 602. The top plate 602 is slidably connected to the inner wall of the outer casing 601. By rotating the knob 7, the screw 8 is driven to rotate, and then the screw 8 moves axially with the cooperation of the threaded hole. This causes the top plate 602 to move along the inner wall of the outer casing 601, thereby adjusting the preset length of the spring 603 and the preload of the spring 603, so as to adjust the pressure when the pressure of the spring 603 decays.

[0031] The clamping component 5 includes two cylindrical clamping rods 501. The two clamping rods 501 are fixedly connected to the same connecting rod 502 at their close ends. The bottom end of the connecting post 605 is rotatably connected to the surface of the connecting rod 502. By setting the clamping rods 501 that are rotatably connected to the connecting post 605 and are cylindrical, the friction between the roller blind 2 and the clamping rods 501 when the roller 1 is wound up is reduced, thus reducing the load.

[0032] A motor 10 is fixedly connected to one side of the receiving box 4. The output end of the motor 10 passes through the inner wall of the receiving box 4 and is fixedly connected to the roller 1. Two baffles 11 are fixedly connected to the surface of the roller 1. The output end of the motor 10 drives the roller 1 to rotate, thereby rolling up the roller curtain 2. The display height of the advertising curtain 3 can be adjusted as needed.

[0033] The bottom of the container box 4 is fixedly connected to a U-shaped frame 12. Limiting grooves 13 are opened on both sides of the inner wall of the frame 12. A movable rod 14 is provided in the limiting groove 13. The movable rod 14 is detachably connected to the bottom of the advertising curtain 3. By setting the frame 12 and the movable rod 14, the stability of the advertising curtain 3 is improved. At the same time, the movable rod 14 is counterweighted to facilitate the opening and closing of the roller blind 2. The bottom end of the advertising curtain 3 is connected to the movable rod 14 by a pressure strip and bolts (not shown in the figure) to facilitate the replacement of the advertising curtain 3.

[0034] Working principle: When using this movable advertising curtain, the user first connects the top of the advertising curtain 3 to the roller blind 2, then connects the bottom of the advertising curtain 3 to the movable rod 14, and then starts the motor 10. The output end of the motor 10 drives the roller shaft 1 to rotate. The rotation of the roller shaft 1 rolls up the material, and the roller blind 2 drives the advertising curtain 3 to flatten in the vertical direction and reach a suitable height for display. During this process, the spring 603 applies dynamic pressure to the sliding plate 604, which in turn generates dynamic pressure on the connecting column 605, and then generates dynamic pressure on the clamping member 5. Under the action of the spring 603, the clamping rod 501 continues to press tightly against the surface of the roller blind 2 during the rolling process, forming radial pressure. When the roller blind 2 momentarily loosens, the spring 603 pushes the clamping rod 501 to fill the loose gap, forcing the roller blind 2 to fit tightly against the roller shaft 1, preventing loosening and winding, thus enabling the movable advertising curtain to have the effect of preventing the roller blind from loosening.
