Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen with a protective structure. Background Art

[0002] Liquid crystal display is a display technology widely used in electronic devices. It uses the properties of liquid crystal materials to adjust light to display images. Liquid crystal itself does not emit light, so LCD screens usually require a backlight to illuminate the liquid crystal layer to display images.

[0003] Due to their precision and fragility, LCD screens require special protection during transportation to avoid damage. Nowadays, shockproof packaging materials designed specifically for electronic devices are needed when transporting LCD screens, such as foam, bubble bags, cartons, etc., to ensure that there is enough cushioning material around the display to prevent the display from being damaged due to vibration and impact during transportation.

[0004] However, there are the following problems in actual application in real life: nowadays, most people will discard the shell and foam and other objects wrapping the LCD screen after receiving the purchased LCD screen. As a result, when the user needs to transport the LCD screen to a distant place, due to the lack of sufficient protective materials on hand, it is impossible to ensure that the screen will not be damaged due to vibration and impact during transportation. In view of this, a LCD screen with a protective structure is provided to overcome the above defects. Utility Model Content

[0012] As a further description of the above technical solution: a second card slot is opened on one side of the second clamping block, and the second card slot is slidably connected to a protective plate, and the protective plate is located directly above the LCD screen body. By setting the protective plate, the LCD screen body is protected during transportation to prevent it from being damaged when being touched by sharp objects.

[0013] The utility model has the following beneficial effects:

[0014] The liquid crystal display screen with a protective structure designed by the utility model is combined with the first clamping block, the second spring, the cylindrical member and other components through design coordination, and the liquid crystal display screen body is fixed by placing the liquid crystal display screen body inside the first card slot opened by the first clamping block, so that the external impact on the liquid crystal display can be buffered by the first rubber pad and the second return spring and other components arranged on the first clamping block, thereby preventing the liquid crystal display screen body from being damaged due to vibration and impact.

[0015] The liquid crystal display screen with a protective structure designed by the utility model combines components such as a protection plate, a second card slot, and a second clamping block through design coordination. The sliding plate is driven to open by pulling the second clamping block, and then the protection plate is slid along the second card slot provided on the second clamping block. After the pulling on the second clamping block is released, the second clamping block is driven to reset by the rebound effect of the first spring. In this way, not only the protection plate can be fixed, but also the protection plate can be used to prevent the liquid crystal display screen body from being damaged when it is hit by a sharp object.
