Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a display screen with waterproof protection. Background Art

[0002] With the development of electronic information technology, display screens are widely used in a variety of fields, including industrial control, traffic monitoring, advertising, and smart homes. However, due to their lack of effective waterproofing, traditional display screens are susceptible to internal circuit shorts, screen blur, and even damage when exposed to rain, splashing liquids, or moisture in the air, particularly in outdoor or humid environments. This can affect their normal operation and service life.

[0003] Current display screens have poor waterproofing. When water splashes onto the screen, it can easily penetrate the gap between the screen and the housing and enter the interior of the display screen, causing damage to the display screen. Furthermore, the display screens are exposed and easily damaged when impacted. Therefore, we propose a display screen with waterproof protection. Summary of the Invention

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example: Figures 1-6 As shown, the present invention provides a display screen with waterproof protection, including a support frame 1, a shell 2 is slidably connected to the interior of the support frame 1, a waterproof plate 3 is slidably connected to one side of the shell 2, a main airbag 4 is fixedly installed on one side of the interior of the shell 2, a sealing airbag 5 is fixedly installed on the other side of the interior of the shell 2, and one side of the sealing airbag 5 is in contact with the waterproof plate 3, an air pump 6 is fixedly installed inside the shell 2, and the output end of the air pump 6 is fixedly connected to a connecting pipe 7, and the connecting pipe 7 is respectively connected to the main airbag 4 and the sealing airbag 5.

[0028] Among them, a driving motor 8 is fixedly installed at the lower end of the interior of the shell 2, and the output end of the driving motor 8 is connected to a bidirectional screw rod 9 for transmission. The outer periphery of both ends of the bidirectional screw rod 9 is threadedly connected to a limit rod. The limit rod 10 is driven by the rotation of the bidirectional screw rod 9 to move horizontally in the shell 2, which is used to adjust the position of the display screen and realize the clamping positioning function.

[0029] A square groove 11 is provided at the lower end of one side of the inner side of the support frame 1 , a worm 12 is rotatably connected to the inner side of the lower end of the support frame 1 , a worm wheel 13 is rotatably connected to the inner side of the square groove 11 , and the outer periphery of the worm 12 is transmission-connected to the worm wheel 13 .

[0030] Among them, sliding grooves 14 are opened on both sides of the interior of the support frame 1, and threaded rods 15 are rotatably connected to the interior of the two sliding grooves 14, and the bottom of one of the threaded rods 15 is fixedly connected to the upper end of the worm gear 13, and the tops of the two threaded rods 15 are fixedly connected to bevel gears 16, and the outer peripheries of the two bevel gears 16 are transmission-connected to bevel gears 17, and one side of the two bevel gears 17 is fixedly connected by a connecting column 18. Through the cooperation of the bevel gears 16 and the bevel gears 17 at the tops of the two threaded rods 15, the two threaded rods 15 can move synchronously.

[0031] Among them, threaded blocks 19 are fixedly connected to both ends of the outer periphery of the shell 2, and the threaded blocks 19 are threadedly connected to the threaded rod 15. The threaded rod 15 rotates in conjunction with the bevel gear 16 and the bevel gear 17, thereby driving the shell 2 to slide up and down along the slide groove 14 in the support frame 1, thereby realizing flexible adjustment of the height of the display screen.

[0032] A cooling pipe 20 is provided inside the main airbag 4 and is fixedly connected to the inner wall of the shell 2 . One end of the cooling pipe 20 is fixedly connected to a water outlet pipe 21 , and the other end of the cooling pipe 20 is fixedly connected to a return pipe 22 .

[0033] Among them, the support frame 1 is fixedly connected to the base 23, and a cavity 24 is opened inside the base 23. A water pump 25 is fixedly installed inside the cavity 24, and the output end of the water pump 25 is connected to the water outlet pipe 21, and the outside of the base 23 is connected to the return pipe 22. A chiller 26 is fixedly installed inside the cavity 24, which is connected to the water outlet pipe 21 through the output end of the water pump 25, and the return pipe 22 is connected to the outside of the base 23, forming a complete water cooling circulation system, which can effectively reduce the temperature of the display screen inside the shell 2 and ensure the stable operation of the display screen.

[0034] Among them, a transparent observation window 27 is fixedly embedded inside the waterproof board 3, and inclined surfaces are provided on both sides of the top of the support frame 1. The inclined surface design on both sides of the top of the support frame 1 is conducive to the rapid sliding of rainwater, preventing accumulated water from seeping into the interior of the equipment, and enhancing the overall waterproof performance.

[0035] Working principle: When in use, install the display screen inside the shell 2, and slide the waterproof plate 3 to make it fit the front surface of the shell 2, start the drive motor 8, the drive motor 8 drives the bidirectional screw 9 to rotate, thereby controlling the movement of the limit rod 10 to achieve fine-tuning of the display screen positioning, start the air pump 6, and the air pump 6 inflates the main air bag 4 and the sealing air bag 5 through the connecting pipe 7, so that the sealing air bag 5 expands and presses the waterproof plate 3, thereby achieving a high-tightness connection between the shell and the waterproof plate to prevent water vapor or liquid from penetrating through the gap. When it is necessary to adjust the display screen, When the screen height is adjusted, the worm 12 is controlled to rotate by the outside, driving the worm gear 13 to rotate. The worm gear 13 drives the threaded block 19 to move up and down through the transmission system composed of the threaded rod 15, the bevel gear 16, the bevel gear 17 and the connecting column 18, thereby driving the shell 2 to rise and fall along the slide groove 14 in the support frame 1 to achieve the height adjustment function. In order to improve the stability of the equipment in a high temperature environment, a cooling pipe 20 is provided inside the main airbag 4. One end of the cooling pipe 20 is connected to the water pump 25 through the outlet pipe 21, and the other end is connected to the base 23 through the return pipe 22. The chiller 26 is arranged in the cavity 24 of the base 23, and can circulate cooling water to achieve effective control of the internal temperature of the shell 2, preventing the performance of the display screen from being degraded due to high temperature. A transparent observation window 27 is embedded in the waterproof board 3, which is convenient for users to view the screen content; the top of the support frame 1 is provided with an inclined surface design, which is conducive to the sliding of rainwater and further enhances the waterproof effect. In summary, the present invention realizes all-round waterproof protection and environmental adaptability of the display screen, has the advantages of reasonable structure, convenient operation, excellent protection performance, etc., and is suitable for various complex environments such as outdoor and humid environments.
