[0002] A touch screen, also known as a touch screen or touch panel, is an advanced interactive input device that uses inductive liquid crystal display technology to receive input signals from users through contacts such as fingers or light pens. When a user touches a graphic button on the screen, the tactile feedback system drives various connection devices according to a pre-programmed program to achieve interactive operations with the computer. Touch screen technology is simple to operate and flexible to use, which greatly facilitates users. It has become the most acceptable computer input method for ordinary people after keyboards, mice, handwriting tablets, and voice input. Touch screens have been widely used in many fields such as mobile phones, tablets, retail, public information inquiries, multimedia information systems, etc., and have become an indispensable human-computer interaction device in modern society.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model aligns the periphery of the mounting back plate with the placement opening, and then presses the protective shell downward to connect the first waterproof groove with the first waterproof ring, and connects the second waterproof groove with the second waterproof ring. At this time, a display screen is provided on the back of the observation window, which is convenient for users to watch and adjust with their fingers. As the protective shell is installed, the mounting back plate continues to move into the placement opening. At this time, when the ball moves to the edge of the mounting back plate, the movable block shrinks into the circular hole. When the belt moves to the circular hole, the spring expands outward and pushes the movable block to move toward the circular hole. The position of the movable block will not shift when it moves through the setting of the limit block and the limit groove, and the ball can be stably placed in the circular hole. At this time, the protective shell and the mounting back plate are installed, which is conducive to the normal operation of the touch screen underwater without damage caused by water intrusion, which greatly increases the reliability and durability of the device and extends the service life of the device.

[0017] 2. When the display screen needs to be moved underwater, the utility model starts the motor to rotate the threaded rod, and the moving block is moved left and right on the threaded rod by setting the threaded holes on the moving block. When the position of the display screen needs to be adjusted downward or upward, the telescopic rod is moved up and down by controlling the pneumatic cylinder, which is beneficial for users to more flexibly adjust the angle and position of the display screen to better view the content. This flexibility and convenience greatly enhances the user experience when operating underwater. BRIEF DESCRIPTION OF THE DRAWINGS
