[0012] The utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, the sealed waterproof mobile phone LCD display screen puts the screen into the shell and then presses the display screen, so that the display screen squeezes the airbag, and at the same time drives the gas into the trachea and then into the air pressure cabin, thereby driving the air pressure rod to move, and at the same time the two clamps move with it, so as to fix the display screen. When the display screen needs to be replaced, it is only necessary to pull the air release valve arranged on the side of the air pressure cabin to restore the clamp, and then the air bag is restored through the air inlet valve arranged at the lower end of the air bag, so that the display screen can be quickly replaced.

[0014] 2. Compared with the prior art, the sealed waterproof mobile phone LCD display screen restores the splint by toggling the cover plate fixedly connected to the side of the fixed block and then pulling the air release valve, and then restores the cover plate through the torsion spring rod arranged inside the protective shell, thereby preventing people from accidentally touching it, and further enhancing the practicality of the device.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-4 The utility model embodiment is a sealed waterproof mobile phone liquid crystal display screen, which includes a shell 1, a sealing ring 2 is arranged inside the shell 1, a fixing mechanism 3 is arranged inside the shell 1, and a protection mechanism 4 is arranged on the side of the fixing mechanism 3.

[0025] The fixing mechanism 3 includes an airbag 31, and an air inlet valve 32 is provided at the lower end of the airbag 31. An air pipe 33 is fixedly connected to the side of the airbag 31, and an air pressure chamber 34 is fixedly connected to the side of the air pipe 33. The air pressure chamber 34 is arranged on the side of the shell 1, and the air pressure chamber 34 is fixedly connected to the side of the shell 1, so that the air pressure chamber 34 is better fixed. A gas pressure rod 35 is arranged on the side of the air pressure chamber 34, and a splint 36 is fixedly connected to the side of the gas pressure rod 35. There are two splints 36, and the two splints 36 are set in a symmetrical state. The splint 36 is arranged inside the shell 1, and the splint 36 is slidably connected to the inside of the shell 1, so that when the splint 36 moves, it is limited by the shell 1, so that the splint 36 can move left and right more stably, and an air release valve 37 is arranged on the side of the air pressure chamber 34.

[0026] The protection mechanism 4 includes a protection shell 41, a torsion spring rod 42 is arranged inside the protection shell 41, a fixed block 43 is fixedly connected to the surface of the torsion spring rod 42, the fixed block 43 is arranged inside the protection shell 41, and the fixed block 43 is rotatably connected to the inside of the protection shell 41, so that when the fixed block 43 rotates, the protective shell 41 is limited, so that the fixed block 43 can rotate more stably, and the side of the fixed block 43 is fixedly connected to the cover plate 44.

[0027] Working principle: When in use, first put the screen into the housing 1, and then press the display screen, so that the display screen squeezes the airbag 31, and at the same time drives the gas in the airbag 31 into the air pipe 33 fixedly connected to the side of the airbag 31, and then enters the air pressure cabin 34 fixedly connected to the side of the air pipe 33, thereby driving the air pressure rod 35 set on the side of the air pressure cabin 34 to move, and at the same time drives the two clamps 36 fixedly connected to the side of the air pressure rod 35 to move, thereby fixing the display screen. When the display screen needs to be replaced, just pull the air pressure cabin 34 side.
