Description

Technical Field

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

[0002] Liquid crystal display is a flat-panel display technology that uses the characteristics of electric fields and liquid crystal molecules to control light and display various images. It consumes relatively little electricity during operation and can present relatively clear and detailed images, such as televisions, computer monitors, mobile phones, and the display screens of some medical instruments. However, LCD screens also have some limitations, and color and brightness may change when viewed from certain angles.

[0003] The existing patent (publication number: CN219243089U) discloses an outdoor waterproof display screen, which relates to the field of display screen technology, including a display screen body and a bracket, wherein the display screen body includes a liquid crystal screen and a socket, a mounting plate is installed on the bracket, and the bracket is used to support the display screen body, and a mounting block is installed on the mounting plate, wherein the mounting block is perpendicular to the mounting plate. During installation, the mounting block is inserted into the slot. Since the mounting block is parallel to the mounting plate, the mounting block is supported by the slot, thereby connecting the connecting plate to the mounting plate, supporting the connecting plate through the mounting plate, and then elastically deforming the fixings on the connecting plate to fix the connecting plate to the mounting plate. When connecting the display screen body and the bracket, the connection is made by the elastic deformation of the fixings, without the aid of additional tools, simplifying the installation steps and making it easier for users to install the display screen body. In the process of realizing the present utility model, the inventor found that the prior art has the following problems:

[0004] 1. When the outdoor display screen encounters rainy weather during use, rain will fall directly on the display screen, which may easily cause water to enter the display screen and cause problems with the display screen;

[0005] 2. The display screen height cannot be adjusted. When viewing the display screen outdoors, if the display screen height is not adjusted according to the viewing angle, changes in color and brightness may occur, affecting the viewing experience.

[0006] Therefore, the present invention provides a waterproof liquid crystal display screen to solve the problems raised in the above background technology. Utility Model Content

[0010] Furthermore, the upper surface of the second support plate is fixedly connected to the first chute, and the first chute and the second chute are both electrically connected to an external power supply;

[0011] Furthermore, the third rain shield is provided with limiting holes inside, and the limiting holes are multiple and linearly distributed;

[0012] Through the above technical solution, by inserting the limiting blocks into different limiting holes, the pulling-out length of the third rain shield can be adjusted and the third rain shield can be limited.

[0013] Furthermore, the inner surface of the second chute is slidably connected to the second rain shield, and the lower surface of the third rain shield is fixedly connected to a pull plate;

[0014] Through the above technical solution, the third rain shield can be easily pulled out.

[0015] Furthermore, the left end of the spring is fixedly connected to the locking switch, and the right end of the spring is fixedly connected to the first rain shield;

[0016] Through the above technical solution, the compression and rebound of the spring drive the limit block to move.

[0017] Furthermore, a second slider is slidably connected to the side surface of the second groove, and a guide rod is slidably connected to the interior of the second slider;

[0018] Furthermore, a nut is threadedly connected to the side surface of the threaded rod, and a handle is fixedly connected to the upper end of the threaded rod;

[0019] With the above technical solution, the handle can rotate the threaded rod more easily, and the lower surface of the nut contacts the upper surface of the second fixing rod, making the device more stable.

[0020] Furthermore, universal wheels are fixedly connected to the lower surface of the first support plate, and the number of the universal wheels is four and they are distributed in a rectangular shape;

[0021] Through the above technical solution, the universal wheels can drive the device to move more easily, making it convenient to move during outdoor use.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a waterproof LCD screen, which can adjust the height of the display screen and rain shield by rotating the threaded rod to drive the slider and the display screen. When viewing the display screen outdoors, the height of the display screen can be adjusted according to whether the viewer is standing or sitting, and there will be no changes in color and brightness due to inappropriate viewing angles, thereby improving the viewing effect.

[0024] 2. The utility model proposes a waterproof LCD screen, in which the rain shield device and the height of the screen can be adjusted simultaneously. When it rains, the rain shield can be unfolded by sliding a groove and pressing a locking switch. The rain shield can be unfolded twice to better shield the screen from rain.
