Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, a wear-resistant liquid crystal display screen comprises a body 3 and a protective shell, wherein the protective shell is made of PPS plastic, and the PPS plastic has the advantages of hardness, brittleness, high crystallinity, flame retardancy, good thermal stability, high mechanical strength, excellent electrical property and the like, and has the characteristics of strong chemical corrosion resistance and the like. The protective housing comprises a base 2 and a housing cover 1, a body 3 is fixedly arranged on the base 2 through screws, a viewing window 11 is arranged on the top end of the housing cover 1, the viewing window 11 faces the screen of the body 3, and a user can see the content on the screen through the viewing window 11. The casing cover 1 is internally detachably connected with a glass plate 10, and the glass plate 10 is abutted against the top end inside the casing cover 1 and covers the whole viewing window 11. The left side of the shell cover 1 is provided with a mounting groove, and a user can slide and insert the glass plate 10 into the shell cover 1 through the mounting groove. The articulated closing plate 5 that is provided with on the mounting groove, closing plate 5 be elastic material make and with mounting groove interference fit, when the user need dismouting glass board 10 because glass board 10 is scraped the flower, need open closing plate 5 downwards earlier to accomplish the dismouting back and upwards close closing plate 5.

Keep away from both sides in cap 1 and all be provided with the dead slot, and the dead slot is located the one end of keeping away from the mounting groove in cap 1. Clamping pieces 8 are rotatably arranged in the empty grooves, and the clamping pieces 8 in the empty grooves at two ends are symmetrically arranged. The clamping piece 8 is provided with a clamping block, the glass plate 10 is provided with a clamping groove matched with the clamping block, the clamping piece 8 is provided with a top block, and the top block and the clamping block form a U shape with different lengths at two ends. When a user inserts the glass plate 10 into the housing cover 1, the user will push the top block forward. The movement of the top piece causes the clamping member 8 to rotate, thereby causing the clamping piece to move and extend out of the empty slot and eventually engage the clamping slot, clamping the glass sheet 10 and securing it. The shell cover 1 is internally provided with a V-shaped elastic piece 9, one end of the elastic piece 9 is fixedly connected with the shell cover 1, and the other end of the elastic piece is abutted against the ejector block. The resilient member 9 exerts an inward force on the top block, and when the user removes the glass sheet 10, the resilient member 9 pushes the top block inward, causing the clamping member 8 to rotate and the clamping block to retract into the recess. So that the next glass plate 10 is not blocked by the clamping block when being installed, and can be pressed against the top block again to enable the clamping block to be embedded into the clamping groove.

A pushing group is arranged in the shell cover 1, and the pushing assembly comprises a first pushing block 4 and a second pushing block 6. The first push block 4 is hinged with the second push block 6, the second push block 6 is located inside the shell cover 1, and the first push block 4 is located outside the shell cover 1. The first push block 4 and the second push block 6 are horizontally arranged on the shell cover 1 in a sliding mode, and the second push block 6 is abutted to the glass plate 10. When a user needs to take out the glass plate 10, the closing plate 5 is opened, the first pushing block 4 is rotated to be horizontal to the second pushing block 6, and then the pushing block is pushed inwards, so that the glass plate 10 is pushed outwards out of the shell cover 1 by the second pushing block 6. Finally, the glass plate 10 is taken down, a new glass plate 10 is directly embedded, and the closing plate 5 is covered, so that the replacement operation can be completed, and the glass plate replacement device is simple and convenient. The housing cover 1 is provided with a receiving groove 7 at the outer side, and when the first pushing block 4 is not needed, the first pushing block can be turned downwards to be embedded into the receiving groove 7 so as to prevent collision or mistaken touch.
