Description

Technical Field

[0001] The utility model belongs to the technical field of digital media display equipment, and in particular relates to a digital media display device. Background Art

[0002] Digital media belongs to the category of engineering disciplines and refers to information carriers that record, process, disseminate, and acquire information in the form of binary numbers. These carriers include sensory media such as digitized text, graphics, images, sounds, video images, and animations, and representation media (coding) that represent these sensory media, commonly known as logical media, as well as physical media that store, transmit, and display logical media, which are usually projected on a screen with the help of a projector.

[0003] Digital media carries most of the information dissemination and display functions in today's society. Now in public activity places, information display screens have almost become standard, and people have become accustomed to obtaining information on such devices. However, in outdoor environments, dust often adheres to the display screen during use. The dust cannot be cleaned in time after being put away. After a long time, the display screen will have low clarity, affecting people's viewing. For example, announcement No. CN214475789U discloses a digital multimedia media teaching display device, which can place some physical objects on the main body of the teaching display device for display by setting an object display component, wherein the object display component includes a slot, a hinge, a support plate, a support slot, a support rod, a placement slot and a protruding block. By adjusting the height of the lifting base, students in the back row can clearly watch the teaching, thereby improving the teaching quality. However, it can be clearly seen that the device still has the following defects when in use:

[0004] 1. The device is a fixed display mechanism, which cannot effectively recycle the projection screen during use, resulting in the inability to effectively protect the projection screen during use, which easily causes dust to accumulate on the screen surface, affecting the display effect;

[0065] As a preferred solution, the adjustment assembly includes a third bevel gear 62, a fourth bevel gear 63, a crawler belt 64 and a belt reel 66; wherein

[0066] The third bevel gear 62 is disposed at the end of the third rotating disk 61, and the third bevel gear 62 is driven to rotate by rotating the third rotating disk 61;

[0067] The four-helical gear 63 and the belt reel 66 are both arranged on the positioning sleeve 65, and the four-helical gear 63 and the third helical gear 62 are meshed with each other;

[0068] The crawler belt 64 is arranged on two adjacent belt reels 66 and meshes with the belt reels 66. When in use, the transmission effect of the crawler belt 64 drives other positioning members 67 to move upward or downward, act on the ground, and position the device.

[0069] The use process and principle of the digital media display device described in Examples 1 to 4 include:

[0070] 1. When in use, the position of the device is moved by rotating the roller 8 as needed, and after moving to the set position, the third rotating disk 61 is rotated, and the positioning member 67 is driven by the third rotating disk 61 and the crawler 64 to move upward or downward, and acts on the ground to position the device;

[0071] 2. After the device is positioned, when it is necessary to change the angle of projection and display, the second turntable 41 is rotated, and the display box 1 is driven to rotate through the meshing force between the first bevel gear 42 and the second bevel gear 43 to achieve the change of angle of projection and display, thereby meeting the use requirements;

[0072] 3. During projection and display, the first turntable 32 is rotated so that the two screen positioning members 35 move toward or away from each other, thereby realizing the unfolding and winding of the screen 36 to meet the projection and display requirements of different sizes.

[0073] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
