SUMMERY OF THE UTILITY MODEL

In order to solve the problems that gaps reserved between a panel and a touch screen are difficult to prevent dust and water, the touch screen is inconvenient to operate by function keys or icons close to four sides, and the like in the conventional touch screen structure, the utility model adopts the following scheme:

the utility model provides a touch-sensitive screen fixed knot constructs, includes touch pad, LCD screen and panel, its characterized in that still includes the silica gel frame, and this silica gel frame inboard is equipped with first recess, and the outside has the second recess, the groove top of first recess is located same horizontal plane with the groove top of second recess, during the installation, the touch pad is fixed the LCD screen top surface, touch pad and LCD screen whole assembly are in first recess, the panel assemble in the second recess, after the assembly is accomplished, the touch pad is located same horizontal plane with the top surface of panel.

Furthermore, the top surface of the silica gel frame is of an arc-shaped structure, the inner side of the silica gel frame is smoothly transited to the touch pad, and the outer side of the silica gel frame is smoothly transited to the panel.

Further, the liquid crystal display panel further comprises a circuit board, the silica gel frame is arranged on the circuit board, the liquid crystal display screen is fixed on the circuit board, screw holes are formed in the circuit board, and the panel is fixed on the circuit board through screws.

Furthermore, the material of panel is panel beating or plastics.

Furthermore, the touch pad is adhered to the top surface of the liquid crystal screen through a double-sided adhesive tape.

Further, the liquid crystal screen is bonded to the circuit board through a double-sided adhesive tape.

The utility model achieves the following beneficial effects:

the touch screen fixing structure ensures that the upper surface of the touch screen and the upper surface of the panel are assembled on the same plane, is attractive and is beneficial to the touch of icons and function keys at the boundary of the touch screen. The silica gel frame not only plays the effect of fixed touch pad, LCD screen and panel, but also plays dustproof and waterproof's effect, can effectively prevent to produce the water smoke between touch-sensitive screen and the LCD screen simultaneously.
