Description

Technical Field

[0001] This utility model relates to the field of media display technology, specifically to a media display device. Background Technology

[0002] Media is the medium for disseminating information. Media display installations refer to dynamic exhibits created using multimedia technology and interactive design, through various media such as sound, light, and electricity, to provide visitors with a novel audiovisual experience. Media display installations are widely used in exhibitions, retail stores, public service institutions, and other scenarios. They not only enrich the form of exhibitions but also attract the audience's attention through high-tech display techniques, enhancing the interactivity and interest of exhibitions.

[0003] Existing patent publication number CN219910194U discloses a digital media display device, relating to the field of display equipment technology. It includes a connecting frame with a rotating groove on its top surface. A display screen is rotatably connected to the inner wall of the rotating groove. Limiting grooves are formed on both outer walls of the connecting frame. A connecting rod is provided on one side of the display screen. A folding tarpaulin is fixedly connected to the outer wall of the connecting rod. Limiting pulleys are fixedly connected to both ends of the connecting rod, and the limiting pulleys are movably connected to the inner wall of the limiting groove. This invention, by pulling the connecting rod, causes the limiting pulleys to move within the limiting groove, pulling the folding tarpaulin above the display screen to block sunlight from directly hitting the screen surface and causing refracted light. This allows the display screen to display content more clearly, making it easier for exhibitors to view the content.

[0004] The above-mentioned solution has the following problems during implementation. While the device uses a sliding connecting rod to unfold the folding tarpaulin to shield the display screen from sunlight during outdoor use, after the folding tarpaulin is pulled above the display screen using the connecting rod, a bolt needs to be manually and slowly turned until it presses down on the limiting pulley. This allows the limiting pulley to be fixed by friction, thus limiting and fixing the connecting rod and the folding tarpaulin. This operation is cumbersome and laborious. Furthermore, relying solely on friction for fixing means that if a worker with less strength doesn't press the bolt down on the limiting pulley tightly enough, the friction may be insufficient, causing the connecting rod to slip and the folding tarpaulin to move, affecting the sunshade effect on the display screen and significantly reducing the device's practicality. Therefore, we provide a media display device to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a media display device that solves the problem in the prior art where, after the connecting rod pulls the folding tarpaulin above the display screen, it is necessary to manually and slowly turn the bolt until it is turned down to press down the limiting pulley, which can then be fixed by friction. This operation is cumbersome and laborious. Moreover, since the fixing is only based on friction, if the operator is not strong enough, the bolt may not press down on the limiting pulley tightly enough, resulting in insufficient friction. This can easily cause the connecting rod to slip, causing the folding tarpaulin to move, thus affecting the sunshade effect on the display screen and greatly reducing the practicality of the device.

[0006] This utility model provides the following technical solution: a media display device, including a base, a support rod installed at the top of the base, a U-shaped frame installed at the top of the support rod, a display screen installed inside the U-shaped frame, fixed seats fixedly connected to both ends of the outer wall of the U-shaped frame, a sliding groove opened on the surface of each set of fixed seats, a sunshade mechanism for blocking sunlight provided on the outer side of the U-shaped frame, and a limiting component for limiting and fixing the sunshade mechanism provided on one side of the U-shaped frame.

[0007] As a preferred embodiment of the above technical solution, the side end of the U-shaped frame is connected to a limiting baffle. The limiting component includes a second movable groove, which is opened on the side end of the U-shaped frame near the limiting baffle. A second spring is installed on the inner side of the second movable groove. A limiting block is slidably installed at the opening of the second movable groove, and the inner end of the limiting block is connected to the second spring.

[0008] The above technical solution allows for the limiting and fixing of the movable rod and support frame, thereby securing the folding tarpaulin. This enables the folding tarpaulin to be more securely mounted on the upper side of the display screen, providing better sun protection. Moreover, the operation is simple and labor-saving, greatly increasing the practicality of the device.

[0009] As a preferred embodiment of the above technical solution, the sunshade mechanism includes several sets of sliders and several sets of locking components. The sliders are slidably installed in the slide grooves. Each set of sliders has a sleeve rod installed at its outer end. Each set of sleeve rods has a movable rod slidably installed inside. Each set of movable rods is limited and fixed inside the sleeve rod by the locking components. A support frame is installed at the end of each pair of corresponding movable rods away from the slider. The surface of the support frames is covered with a folding tarpaulin.

[0010] The above technical solution enables the display screen to be shaded, better preventing sunlight from directly hitting the surface of the display screen and causing refracted light that affects viewing, thus allowing exhibitors to better view the displayed content.

[0011] As a preferred embodiment of the above technical solution, each set of locking components includes a movable groove and two sets of limiting holes. Each set of movable grooves is opened on the side of the movable rod surface near the slider. A spring is installed on the inner side of each set of movable grooves. A limiting rod is slidably installed at the opening of each set of movable grooves, and the inner end of the limiting rod is connected to the spring. Each pair of springs is opened on the side of the sleeve rod surface near the slider and the side of the sleeve rod surface away from the slider, respectively.

[0012] The above technical solution can shorten the distance between the folding tarpaulin and the U-shaped frame, thereby reducing the space occupied by the device and making it easier to store.

[0013] As a preferred embodiment of the above technical solution, the inner end of the limiting block is connected to a pull rod, the end of the pull rod away from the limiting block passes through the U-shaped frame and extends to the inner side of the U-shaped frame, and the end of the pull rod away from the limiting block is connected to a connecting plate.

[0014] The above technical solution allows the limitation on the movable lever to be released, making operation more convenient.

[0015] As a preferred embodiment of the above technical solution, a pull ring is hinged to the end of the connecting plate away from the pull rod.

[0016] The above technical solution makes it more convenient to pull the ring to drive the connecting plate. Moreover, the hinge design allows the ring to be folded up, making it even more convenient.

[0017] As a preferred embodiment of the above technical solution, the bottom of the base is equipped with several sets of omnidirectional wheels.

[0018] The above technical solution enables the display screen to be moved by using omnidirectional wheels, making it easier to transport the display screen.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention, by incorporating a sunshade mechanism and a limiting component, allows the folding tarpaulin to be unfolded above the display screen. This provides sunshade, effectively preventing direct sunlight from reflecting off the screen and affecting viewing, thus allowing exhibitors to better view the content. The limiting component and limiting baffle then secure the folding tarpaulin, ensuring it is firmly positioned above the display screen for even better sun protection. Furthermore, the device is simple and labor-saving to operate, greatly increasing its practicality. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, this utility model provides a technical solution: a media display device, including a base 1, a support rod 12 installed at the top of the base 1, a U-shaped frame 13 installed at the top of the support rod 12, a display screen 2 installed inside the U-shaped frame 13, and several sets of universal wheels 11 installed at the bottom of the base 1, so that the display screen 2 can be moved by pushing it through the universal wheels 11, thereby making it easier to move the display screen 2. Fixed seats 14 are fixedly connected to both ends of the outer wall of the U-shaped frame 13, and each set of fixed seats 14 has a sliding groove 15 on its surface. A sunshade mechanism 3 for blocking sunlight is provided on the outer side of the U-shaped frame 13. The sunshade mechanism 3 includes several sets of sliders 31 and several sets of locking components 4. The sliders 31 are slidably installed in the sliding grooves 15, and a sleeve rod 32 is installed at the outer end of each set of sliders 31. A movable rod 33 is slidably installed inside each set of sleeve rods 32. All movable rods 33 are fixed within the sleeve rod 32 by locking components 4. Each pair of movable rods 33 has a support frame 34 installed at the end away from the slider 31. Several sets of support frames 34 are covered with folding tarpaulins 35. This structure allows the support frame 34 closest to the display screen 2 to rotate, which in turn drives the movable rod 33, which in turn drives the sleeve rod 32. The sleeve rod 32 then drives the slider 31 to slide within the slide groove 15 until the support frame 34 closest to the display screen 2 unfolds the folding tarpaulin 35 and places it above the display screen 2. At the same time, the folding tarpaulin 35 also causes the other sets of support frames 34 to rotate at different angles. This provides shade for the display screen 2, better preventing direct sunlight from reflecting off the surface of the display screen 2 and affecting viewing, allowing exhibitors to better view the exhibited content.

[0030] It should be noted that support plates are provided at both ends of the outer wall of the U-shaped frame 13. In this way, the set of sleeves 32 farthest from the display screen 2 can naturally rest on the support plate by gravity, thus providing support and making the sunshade mechanism 3 more stable.

[0031] As one implementation method in this embodiment, such as Figure 4As shown, a limiting component 5 for limiting and fixing the sunshade mechanism 3 is provided on one side of the U-shaped frame 13. A limiting baffle 16 is connected to the side end of the U-shaped frame 13, which can limit the movable rod 33. The limiting component 5 includes a second movable groove 51, which is opened on the side end of the U-shaped frame 13 near the limiting baffle 16. A second spring 52 is installed inside the second movable groove 51. A limiting block 53 is slidably installed at the opening of the second movable groove 51, and the inner end of the limiting block 53 is connected to the second spring 52. This structure allows the movable rod 33 to be pushed by the support frame 34 closest to the display screen 2 when the folded tarpaulin 35 is unfolded above the display screen 2. The support frame 34 will push the movable rod 33 to compress the limiting block 53 until the limiting block 53 is pushed into the second movable groove 51 to compress the second spring 52. This allows the movable rod 33 to rotate between the limiting baffle 16 and the limiting block 53, thus limiting the movement of the movable rod 33 and the support frame 3. 4. Limiting and fixing the folding tarpaulin 35, so that the folding tarpaulin 35 can be more securely set on the upper side of the display screen 2, better shading the display screen 2, and the operation is simple and labor-saving, greatly increasing the practicality of the device. The inner end of the limiting block 53 is connected to the pull rod 54. The end of the pull rod 54 away from the limiting block 53 passes through the U-shaped frame 13 and extends to the inner side of the U-shaped frame 13. The end of the pull rod 54 away from the limiting block 53 is connected to the connecting plate 55, so that pulling the connecting plate 55 drives the pull rod 54, and the pull rod 54 drives the limiting block 53 until the limiting block 53 is pulled into the movable groove 2 51, so that the limitation on the movable rod 33 can be released. The end of the connecting plate 55 away from the pull rod 54 is hinged to the pull ring 56, making it more convenient to drive the connecting plate 55 by pulling the pull ring 56. Moreover, the hinge setting allows the pull ring 56 to be folded up, making it more convenient.

[0032] As one implementation method in this embodiment, such as Figure 6As shown, each locking assembly 4 includes a movable groove 41 and two sets of limiting holes 44. Each movable groove 41 is located on the surface of the movable rod 33 near the slider 31. A spring 42 is installed inside each movable groove 41. A limiting rod 43 is slidably installed at the opening of each movable groove 41, and the inner end of the limiting rod 43 is connected to the spring 42. Each pair of springs 42 is located on the surface of the sleeve rod 32 near the slider 31 and on the surface of the sleeve rod 32 away from the slider 31, respectively. This structure allows the limiting rod 44 to be locked by pressing the limiting rods 43 in sequence. 3. Move out of the limiting hole 44 on the side away from the slider 31 and press it into the movable groove 41 to compress the spring 42. This will push the support frame 34. The support frame 34 will drive the movable rod 33 to slide in the sleeve rod 32 until the movable rod 33 is retracted into the sleeve rod 32. The movable rod 33 will also drive the support frame 34 to move closer to the U-shaped frame 13. When several sets of support frames 34 are close to the U-shaped frame 13, the distance between the folding tarpaulin 35 and the U-shaped frame 13 can be shortened, thereby reducing the space occupied by the device and making it easier to store the device.

[0033] Working principle: To provide shade for the display screen 2, simply pull the set of support frames 34 closest to the display screen 2. The support frame 34 drives the movable rod 33, which in turn drives the sleeve rod 32. The sleeve rod 32 then drives the slider 31 to slide within the slide groove 15 until the set of support frames 34 closest to the display screen 2 unfolds the folding tarpaulin 35 and places it above the display screen 2. Simultaneously, the folding tarpaulin 35 also causes the other sets of support frames 34 to rotate at different angles. This effectively shades the display screen 2, preventing direct sunlight from reflecting off its surface and affecting viewing. This allows exhibitors to better view the displayed content. Furthermore, when the set of support frames 34 closest to the display screen 2 unfolds the folding tarpaulin 35... When the support frame 34 reaches above the display screen 2, the movable rod 33 will press and push the limiting block 53 until the limiting block 53 is pushed into the movable groove 2 51 to compress the spring 2 52. This allows the movable rod 33 to rotate between the limiting baffle 16 and the limiting block 53. At this time, the limiting block 53 loses its compression and will be pushed out into the movable groove 2 51 by the spring force of the spring 2 52. This allows the movable rod 33 to be locked between the limiting baffle 16 and the limiting block 53, thus limiting and fixing the movable rod 33 and the support frame 34, thereby fixing the folding tarpaulin 35. This allows the folding tarpaulin 35 to be more securely set on the upper side of the display screen 2, providing better sun protection for the display screen 2. Moreover, the operation is simple and labor-saving, greatly increasing the practicality of the device.

[0034] Additionally, to fold up the tarpaulin 35, simply pull the pull ring 56. The pull ring 56 drives the connecting plate 55, which in turn drives the pull rod 54. The pull rod 54 then drives the limiting block 53 until it is pulled into the movable groove 2 51. This releases the limiting on the movable rod 33, allowing the support frames 34 to be rotated to one side and stacked. Simultaneously, the support frames 34 can also fold up the tarpaulin 35, greatly increasing the device's convenience. Finally, when folding up the tarpaulin 35, the limiting rod 43 can be pressed sequentially to move it out of the limiting hole 44 on the side away from the slider 31 and press it into the movable groove 1 41 to compress the spring 1 42. This pushes the support frame 34, causing it to move... The movable rod 33 slides within the sleeve rod 32 until it is retracted into the sleeve rod 32. At this point, the limiting rod 43 corresponds to the limiting hole 44 on the side near the slider 31. The limiting rod 43 can then be pushed into the limiting hole 44 on the side near the slider 31 by the spring force of the spring 42, thereby limiting the movable rod 33 within the sleeve rod 32 and making it more stable. After the movable rod 33 is retracted into the sleeve rod 32, it will also drive the support frame 34 to move closer to the U-shaped frame 13 until several sets of support frames 34 are close to the U-shaped frame 13. This shortens the distance between the folding tarpaulin 35 and the U-shaped frame 13, thereby reducing the space occupied by the device and making it easier to store.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
