[ detailed description ] embodiments

The following further describes embodiments of the present invention with reference to the drawings. As shown in fig. 1-9, the present invention is an antistatic structure for a liquid crystal display, comprising an LCD 5, a second metal frame 7, and a display shell 10, wherein the display shell 10 is made of a fiber-reinforced composite material. Copper nut 8 inlays inside display screen shell 10, and electrically conductive bubble 6 pastes to be fixed on second metal support 7, and metal screw 9 passes second metal support 7, is connected with copper nut 8 and fixes on display screen shell 10, and LCD display screen 5 pastes and fixes the opposite side at electrically conductive bubble 6, and display screen 1 passes through hexagon screw 4 to be fixed on first metal support 3. The conductive foam has a conductive function, and is easy to compress and deform under the action of external force, and the fixed LCD display screen 5 extrudes the conductive foam 6, so that the conductive foam 6 is always in a compressed state between the second metal bracket 7 and the LCD display screen 5 and is always in a contact state. The copper shrapnel 11 with the thickness of 0.05mm and the length slightly longer than the inner side face width of the two arms of the first metal support is used, the copper shrapnel 11 is fixed on an aluminum alloy pressing block 12, a plastic damping sheet 14 is embedded and installed inside the aluminum alloy pressing block 12, the two aluminum alloy pressing blocks 12 are installed inside the aluminum alloy pressing block 12 through a countersunk screw 13, four plastic damping sheets 14, the copper shrapnel 11 and the first metal support 3 are installed and fixed on a vertical rod 2, the aluminum alloy pressing block 12 is fixed on the vertical rod 2, the whole face of the inner side aluminum alloy pressing block 12 is in contact with the inner side face of the vertical rod 2, the lower end of the vertical rod 2 is fixedly connected with a product body, and the product body is connected with the ground.

The working principle of electrostatic conduction of the utility model is as follows: since the conductive foam 6 is always in a compressed state, the LCD display 5 and the second metal bracket 7 are always in a contact state, and static electricity of the LCD display 5 is conducted to the second metal bracket 7 through the conductive foam 6. Since the second metal bracket 7 is fixed to the copper nut 8 by the metal screw 9, static electricity is conducted from the second metal bracket 7 to the copper nut 8; the other end of the copper nut 8 is fixedly connected with the first metal bracket 3 through a hexagonal screw 4, so that static electricity is conducted to the first metal bracket 3. As the inner sides of the two arms of the first metal bracket 3 compress the copper shrapnel 11, the static electricity on the first metal bracket 3 is conducted to the copper shrapnel 11 and then is transmitted to the aluminum alloy pressing block 12. Since the aluminum alloy pressing block 12 is in contact with the vertical rod 2, static electricity is conducted to the vertical rod 2 through the aluminum alloy pressing block 12. The vertical rod 2 is connected with the product main body and the ground, and finally static electricity is released.
