This cover plate is processed through multiple processes and has functions such as shock resistance, scratch resistance, oil resistance, fingerprint prevention, and enhanced light transmittance.

[0003] Currently, in actual applications of the protective cover plates on the market, it is found that the gap at the docking position between the inner side of the cover plate and the screen is most likely to accumulate impurities such as dust, and it is not easy to clean the inside of the gap, which extremely affects the subsequent use effect of the display module.

[0004] To solve the above problems, a protective cover plate for a liquid crystal display module is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a protective cover plate for a liquid crystal display module, which solves the problems raised in the above background art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a protective cover plate for a liquid crystal display module, including: a cover plate and a protective film inside it; a limiting frame is arranged on the inner side of the cover plate and is installed inside a bracket on the inner side of the cover plate. A sealing strip is arranged inside the limiting frame, which can be disassembled at any time to form a cavity for convenient cleaning operations; a sealing pad and a positioning pad are arranged inside the sealing strip, which are divided into upper and lower layers. The upper positioning pad applies a pressing force to the lower sealing pad to make it closely fit the bracket to fill the gap and prevent impurities from entering.

[0008] Further, a limiting groove for installing the sealing strip is opened on the inner side of the limiting frame, and an extended inner groove is opened on the outer side of the upper end of the limiting groove.

[0009] Further, a dial block is arranged inside the inner groove, and the limiting state of the sealing strip is controlled by a convex block at its end.

[0010] Further, an extension block is also arranged inside the inner groove, which is located below the dial block, and the outer edge position is adjacent to the inclined surface of the convex block.

[0011] Further, an elastic protrusion is arranged above the sealing strip, which is clamped inside a positioning card slot on the inner side of the extension block.

[0012] Further, the upper part of the shifting block is aligned with the positioning part above the limiting frame. When the positioning part is pressed, the convex block is driven to bend inwards, flattening the positioning card slot and the elastic protrusion, and pushing the sealing strip towards the inner side.

[0013] Further, the limiting frame, the sealing strip and the components inside them are all made of silica gel structure, which is convenient for the use of assembly and disassembly operations.

[0014] The utility model has the following beneficial effects:

[0015] After the utility model is used for a certain period of time through the combined structure of the sealing strip and the limiting frame, the limit of the sealing strip can be directly released by pressing the positioning part. At this time, the sealing strip can be taken out to easily clean the inside of the gap, preventing the influence of long-term accumulation of impurities on the use effect, reducing the cleaning difficulty and ensuring the service life;

[0016] Through the double-layer structure of the sealing gasket and the positioning gasket, while ensuring the beautiful appearance, the inner side can tightly press against the bracket by the pressure applied by the positioning gasket and the sealing gasket to fill the gap, preventing impurities from entering the inside, which is convenient for the daily maintenance of the actual module.
