Technical Field

[0001] The utility model belongs to the technical field of screens, and specifically relates to a rapid screen unfolding structure. Background Art

[0002] The special coating of the screen can enhance the contrast of the picture, improve the color saturation, and make the picture more vivid and lifelike; a high-quality screen can effectively manage the ambient light, reduce interference, and ensure that the picture is still clearly visible in a relatively bright environment.

[0003] When it is necessary to play a video or a movie, the screen usually needs to be unfolded to facilitate the projector to project the picture onto the surface of the screen for the user to watch. The existing screens are usually manually unfolded by the user and then fixed on the bed.

[0004] In the current prior art, since the existing screens usually require manual operation during the unfolding process, the unfolding accuracy and flatness of the corners and the surface are relatively low during the unfolding process of the screen, thereby reducing the projection image quality of the projector; therefore, a rapid screen unfolding structure is proposed for the above problems.

[0005] Therefore, the utility model provides a rapid screen unfolding structure. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A rapid screen unfolding structure of the utility model includes a support table, and a support plate is fixedly connected to the top of the support table; a fixing plate is fixedly connected to the top of the support plate; a motor is fixedly connected to the end of the fixing plate; an output end of the motor is fixedly connected to a winding roller, and the other end of the winding roller is rotatably connected to the inner side wall of the fixing plate; a screen body is installed at the end of the winding roller; a guiding plate is fixedly connected to the end of the screen body; a guiding groove is formed inside the support plate, and the guiding plate is slidably connected to the inner side wall of the guiding groove.

[0008] Preferably, a clamping block is fixedly connected to the bottom of the guiding plate; a locking groove is formed inside the clamping block; a clamping groove is formed inside the support table; a cavity is formed inside the support table and is located at the end of the clamping groove; a locking block is slidably connected to the inside of the cavity; a spring is fixedly connected to the end of the locking block, and the other end is fixedly connected to the inner side wall of the cavity.

[0009] Preferably, a pull rod is fixedly connected to the end of the locking block, and the pull rod is slidably connected to the inside of the support table; a pull handle is fixedly connected to the end of the pull rod.

[0010] Preferably, a cleaning plate is fixedly connected to the end of the fixed plate and is located at the end of the curtain body.

[0011] Preferably, support legs are fixedly connected to the bottom of the support platform and are symmetrically arranged; positioning plates are fixedly connected to the bottoms of the support legs; the bottom of the clamping block is semi-circular; the end of the locking block is semi-circular and matches the clamping block.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. For a curtain rapid deployment structure of the present utility model, by turning on the motor to drive the winding roller to rotate, when the winding roller rotates, the curtain body and the guide plate are deployed. Since the guide plate is slidably connected inside the guide groove, the guide plate drives the curtain body to quickly deploy and move downward along the guide groove. Then, through the guidance of the guide groove, the curtain body is quickly deployed flatly, and through the guidance of the guide groove, the curtain body can be deployed flatly, improving the projection image quality of the projector.

[0014] 2. For a curtain rapid deployment structure of the present utility model, when the guide plate slides downward, it drives the clamping block to insert into the card slot. As it inserts, the locking block is squeezed, causing the locking block to be squeezed and retracted into the cavity, squeezing the spring to generate elastic force. When the locking groove and the cavity are aligned with each other, the elastic force generated by the spring pushes the locking block to insert into the locking groove for clamping and fixing, to fix and limit the curtain body, reducing problems such as shaking of the curtain body, and thus effectively improving the projection image quality of the curtain body.

[0022] The following gives specific embodiments.

[0023] As Figures 1 to 4 shown, the present utility model provides a rapid unfolding structure for a curtain, including a support platform 1, and a support plate 21 is fixedly connected to the top of the support platform 1; a fixing plate 22 is fixedly connected to the top of the support plate 21; a motor 23 is fixedly connected to the end of the fixing plate 22; an output end of the motor 23 is fixedly connected to a winding roller 24, and the other end of the winding roller 24 is rotatably connected to the inner side wall of the fixing plate 22; a curtain body 25 is installed at the end of the winding roller 24; a guiding plate 26 is fixedly connected to the end of the curtain body 25; a guiding groove 27 is formed inside the support plate 21, and the guiding plate 26 is slidably connected to the inner side wall of the guiding groove 27; during operation, when the curtain is needed, the motor 23 is turned on to drive the winding roller 24 to rotate, so that when the winding roller 24 rotates, the curtain body 25 and the guiding plate 26 are unfolded. Since the guiding plate 26 is slidably connected to the inside of the guiding groove 27, the guiding plate 26 drives the curtain body 25 to quickly unfold and move downward along the guiding groove 27, and then through the guiding of the guiding groove 27, the curtain body 25 is quickly unfolded and flattened, and through the guiding of the guiding groove 27, the curtain body 25 can be unfolded flatly, improving the projection image quality of the projector.

[0024] As Figures 3 to 4 shown, a clamping block 31 is fixedly connected to the bottom of the guiding plate 26; a locking groove 32 is formed inside the clamping block 31; a clamping groove 33 is formed inside the support platform 1; a cavity 34 is formed inside the support platform 1 and is located at the end of the clamping groove 33; a locking block 35 is slidably connected to the inside of the cavity 34; a spring 36 is fixedly connected to the end of the locking block 35, and the other end is fixedly connected to the inner side wall of the cavity 34; during operation, when the guiding plate 26 slides downward, the clamping block 31 is driven to insert into the clamping groove 33. As it is inserted, the locking block 35 is squeezed, so that the locking block 35 is squeezed and contracted into the cavity 34 to squeeze the spring 36 to generate elastic force. When the locking groove 32 and the cavity 34 are aligned with each other, the elastic force generated by the spring 36 pushes the locking block 35 to insert into the locking groove 32 for clamping and fixing, so as to fix and limit the curtain body 25, reduce problems such as shaking of the curtain body 25, and thus effectively improve the projection image quality of the curtain body 25.

[0025] As shown Figures 3 to 4 in the figure, a pull rod 41 is fixedly connected to the end of the lock block 35, and the pull rod 41 is slidably connected inside the support table 1; a pull handle 42 is fixedly connected to the end of the pull rod 41; during work, when it is necessary to recycle the curtain body 25, the pull handle 42 is pulled to drive the pull rod 41 to slide laterally, so that the pull rod 41 pulls the lock block 35 to contract into the cavity 34, and then the fixed plate 22 is opened to drive the winding roller 24 to rotate, so as to wind the curtain body 25 and the guide plate 26. During the winding process, the clamping block 31 slides out of the clamping groove 33, which is convenient for subsequent recycling of the curtain body 25.

[0026] As shown Figures 1 to 2 in the figure, a cleaning plate 5 is fixedly connected to the end of the fixed plate 22 and is located at the end of the curtain body 25; during work, by installing the cleaning plate 5 at the bottom of the fixed plate 22, the curtain body 25 can be quickly cleaned when winding and opening, improving the picture quality clarity of the curtain body 25.

[0027] As shown Figures 1 to 2 in the figure, support legs 61 are fixedly connected to the bottom of the support table 1 and are symmetrically arranged; positioning plates 62 are fixedly connected to the bottoms of the support legs 61; the bottom of the clamping block 31 is semi-circular; the end of the lock block 35 is semi-circular and matches the clamping block 31; during work, by installing the support legs 61 and the positioning plates 62 at the bottom of the support table 1, the effects of support and fixation are achieved, effectively improving the overall stability of the support table 1

[0028] Working principle: When the curtain is needed, the motor 23 is turned on to drive the winding roller 24 to rotate. When the winding roller 24 rotates, the curtain body 25 and the guide plate 26 are unfolded. Since the guide plate 26 is slidably connected inside the guide groove 27, the guide plate 26 drives the curtain body 25 to quickly unfold and move along the guide groove 27 towards the bottom. Then, through the guidance of the guide groove 27, the curtain body 25 is quickly unfolded and flattened. And through the guidance of the guide groove 27, the curtain body 25 can be unfolded smoothly, improving the projection image quality of the projector. When the guide plate 26 slides towards the bottom, it drives the clamping block 31 to insert into the clamping groove 33. As it inserts, the locking block 35 is squeezed, causing the locking block 35 to be squeezed and contracted into the cavity 34, squeezing the spring 36 to generate elastic force. When the locking groove 32 and the cavity 34 are aligned with each other, the elastic force generated by the spring 36 pushes the locking block 35 to insert into the locking groove 32 for clamping and fixing, to fix and limit the curtain body 25, reducing problems such as shaking of the curtain body 25, and thus effectively improving the projection image quality of the curtain body 25. When the curtain body 25 needs to be recycled, the pull handle 42 is pulled to drive the pull rod 41 to slide towards the side end, causing the pull rod 41 to pull the locking block 35 to contract into the cavity 34. Then, the fixed plate 22 is opened to drive the winding roller 24 to rotate, to wind up the curtain body 25 and the guide plate 26. During the winding process, the clamping block 31 slides out of the clamping groove 33, facilitating the subsequent recycling process of the curtain body 25. By installing a cleaning plate 5 at the bottom of the fixed plate 22, when the curtain body 25 is wound up and unfolded, it is quickly cleaned by the cleaning plate 5, improving the image clarity of the curtain body 25. By installing support legs 61 and a positioning plate 62 at the bottom of the support platform 1, it plays a role in support and fixation, effectively improving the overall stability of the support platform 1.

[0029] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
