Description

Technical Field

[0001] This utility model relates to the field of LCD screen dustproof technology, specifically a dustproof protection structure for LCD screens. Background Technology

[0002] An LCD screen is constructed by placing liquid crystals between two parallel glass plates. Numerous fine vertical and horizontal wires connect the two plates, controlling the orientation of rod-shaped crystal molecules by applying electricity, thus refracting light to create an image. The basic principle behind the screen's display is filling the space between the two parallel plates with liquid crystal material. Voltage is used to change the arrangement of molecules within the liquid crystal material, achieving light blocking and transmission to display images of varying depths and textures. Furthermore, by adding a three-color filter layer between the two plates, color images can be displayed.

[0003] In everyday use, dust is ubiquitous and difficult to prevent from penetrating even with ordinary protective measures. In relatively clean office environments, fine dust from printers and copiers, as well as dust stirred up by people walking around, gradually accumulates on the LCD screen surface. The situation is even more severe in dusty environments such as factories. A large amount of dust adhering to the screen surface not only affects display clarity but also makes the screen more prone to stains due to electrostatic attraction, significantly impacting the visual experience. Dust that enters the screen can interfere with the normal operation of electronic components, causing display malfunctions such as bright spots, dark spots, and color blocks, thus shortening the LCD screen's lifespan.

[0004] The difficulty in maintaining and replacing dustproof components is also a major problem. Currently, most dustproof components in LCD screens are poorly designed, making cleaning or replacement extremely complicated. Some dustproof meshes are fixed in hard-to-reach locations, requiring specialized tools and even partial disassembly of the screen structure for removal. This not only increases maintenance costs but also increases the risk of secondary damage to the screen due to improper handling. Furthermore, because of the cumbersome replacement process, many users often neglect regular maintenance of dustproof components, causing the dustproof effect to gradually weaken over time, failing to provide sustained effective protection for the LCD screen. Utility Model Content

[0005] The purpose of this invention is to provide a dustproof protection structure for LCD screens to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof protection structure for an LCD screen, comprising an LCD display screen, a dustproof mechanism being provided above the LCD display screen, and mounting mechanisms being provided on the left and right sides of the LCD display screen.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This utility model provides a technical solution:

[0029] Example 1

[0030] Combination Figures 1 to 5 A dustproof protection structure for an LCD screen includes an LCD display screen 3, a dustproof mechanism 1 disposed on the top of the LCD display screen 3, and mounting mechanisms 2 disposed on the left and right sides of the LCD display screen 3.

[0031] The dustproof mechanism 1 includes a dustproof component 11, a reset component 12, a disassembly component 13, and a positioning component 14. The dustproof component 11 is located above the LCD display screen 3, the reset component 12 is located above the dustproof component 11, the disassembly component 13 is located inside the top of the reset component 12, and the positioning component 14 is located at the bottom of the reset component 12.

[0032] Dustproof component 11 includes a frame 1101, which is positioned above the LCD display screen 3. A dustproof cover 1102 is installed inside the frame 1101 and is located on the front side of the LCD display screen 3. Reset component 12 includes a fixing box 1201, which is fixedly connected to the top of the frame 1101. A sliding plate 1202 is slidably connected inside the fixing box 1201. A compression spring 1203 is fixedly connected to the top of the sliding plate 1202 and is fixedly connected to the top of the fixing box 1201. Disassembly component 13 includes a telescopic slide rod 1301. The telescopic slide rod 1301 is fixedly connected to the top of the slide plate 1202 and slidably connected to the top of the fixed box 1201. A pull rod 1302 is fixedly connected to the top of the telescopic slide rod 1301. The positioning component 14 includes a movable slide rod 1401, which is fixedly connected to the bottom of the slide plate 1202 and slidably connected to the top of the frame 1101. A pressure plate 1402 is fixedly connected to the bottom of the movable slide rod 1401 and slidably connected to the frame 1101. A locking block 1403 is fixedly connected to the bottom of the pressure plate 1402 and engages with the top of the dust cover 1102.

[0033] Furthermore: Under the action of the compression spring 1203, the sliding plate 1202 moves the pressure plate 1402 and the locking block 1403 downwards via the sliding rod 1401 to lock and fix the dust cover 1102. No external force is required. The dust cover 1102 is fixed inside the frame 1101 to block the front of the LCD display screen 3, preventing dust in the outside air from directly contacting the front of the LCD display screen 3, thus achieving the effect of dust protection for the LCD display screen 3. The dust cover 1102 has no obvious requirements. It only needs to match the size of the inner side of the frame 1101 and the length can completely cover the front of the LCD display screen 3. The dust cover 1102 of different materials and patterns can be replaced according to the needs of use and the user's own preferences, which is convenient for use. At the same time, the staff only needs to pull the lever 1302 upwards to drive the locking block 1403 upwards to release the positioning of the dust cover 1102, which makes it easier for the staff to disassemble the dust cover 1102 and make it easier to use.

[0034] Example 2

[0035] See Figure 1 , Figure 2 , Figure 4 and Figure 5 Furthermore, based on Embodiment 1, the installation mechanism 2 includes a support component 21, a snap-fit ​​component 22, and a fixing component 23. The support component 21 is disposed at the bottom of the dustproof component 11, the snap-fit ​​component 22 is disposed at the front side of the support component 21, and the fixing component 23 is disposed inside the snap-fit ​​component 22.

[0036] Support component 21 includes a fixing plate 2101, which is fixedly connected to the bottom of frame 1101. The fixing plate 2101 is disposed on the left and right sides of LCD display screen 3. A reinforcing fin 2102 is fixedly connected to the top front side of the fixing plate 2101 and is fixedly connected to the bottom of frame 1101. The snap-fit ​​component 22 includes a snap-fit ​​strip 2201, which is fixedly connected to the front side of the fixing plate 2101. A sleeve block 2202 is snapped onto the outer side of the snap-fit ​​strip 2201. A connecting block 2203 is fixedly connected to the inner side of the sleeve block 2202. The connecting block 2203 is fixedly connected to the left and right sides of the LCD display screen 3. The fixing component 23 includes a bolt 2301. The bolt 2301 is set between the upper and lower side retaining strips 2201. The bolt 2301 is snapped into the sleeve block 2202. The bolt 2301 is fixedly connected to the front side of the fixing plate 2101. A nut 2302 is threadedly connected to the outer ring of the bolt 2301. The nut 2302 is snapped into the front side of the sleeve block 2202.

[0037] Furthermore, workers only need to rotate the nut 2302 to disengage it from the bolt 2301, and then move the frame 1101 backward to complete the overall disassembly of the frame 1101. The installation is the same, which makes it easy for workers to disassemble and assemble the frame 1101 as a whole. Workers can install or disassemble the frame 1101 according to their specific needs. The operation is simple and convenient for workers to use.

[0038] In actual operation, when this device is used and the frame 1101 needs to be installed, the operator first places the frame 1101 behind the sleeve block 2202, so that the retaining strip 2201 and bolt 2301 are aligned with the sleeve block 2202. Then, the frame 1101 is moved forward. The forward movement of the frame 1101 drives the retaining strip 2201 and bolt 2301 to move forward through the fixing plate 2101. The retaining strip 2201 and bolt 2301 move forward and engage inside the sleeve block 2202. Then, the operator rotates the nut 2302 to install it on the outer ring of the bolt 2301. The nut 2302 rotates on the outer ring of the bolt 2301 and moves backward until the nut 2302 is engaged inside the front side of the sleeve block 2202 and can no longer be rotated. At this point, the installation of the frame 1101 is completed.

[0039] When installing the dust cover 1102, the worker first pulls the lever 1302 upwards. The upward movement of the lever 1302 moves the slide plate 1202 upwards via the telescopic slide rod 1301. The upward movement of the slide plate 1202 moves the pressure plate 1402 upwards via the moving slide rod 1401. Then, the worker places the top part of the dust cover 1102 at the bottom of the frame 1101 and releases the pull of the lever 1302. At this time, the slide plate 1202, under the action of the compression spring 1203, moves the pressure plate 1402 and the locking block 1403 downwards via the moving slide rod 1401. The pressure plate 1402 moves downwards to the top of the dust cover 1102 and is locked in place by the locking block 1403, thus completing the installation of the dust cover 1102.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
