Description

Technical Field

[0001] This utility model relates to the field of waterproof mechanisms, and in particular to a waterproof mechanism for an outdoor LED screen. Background Technology

[0002] Outdoor LED displays are increasingly used in advertising, information display, stage backdrops, and other fields. However, the outdoor environment is complex and changeable, requiring LED displays to have good waterproof and moisture-proof performance to ensure stable operation and lifespan under harsh weather conditions.

[0003] In practical use, outdoor LED screens generate heat during operation. The accumulation of heat can cause the internal temperature of the screen to rise, thus affecting the performance of the sealing materials. At the same time, moisture can easily accumulate in the gaps between the screen frame and the LED screen. The long-term presence of moisture not only reduces the sealing effect but may also corrode the electronic components of the LED screen, affecting its lifespan.

[0004] Traditional LED screen installation structures typically require complex fixing devices, making installation and disassembly cumbersome and increasing maintenance costs and time. In some applications, the need for rapid disassembly and replacement of LED screens is also difficult to meet.

[0005] Therefore, it is necessary to propose a waterproof mechanism for outdoor LED screens to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a waterproof mechanism for outdoor LED screens, so as to solve the problems of unstable sealing effect, complex installation, high maintenance cost and inability to effectively deal with moisture accumulation in existing outdoor LED screen waterproof structures and installation methods.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof mechanism for an outdoor LED screen, comprising:

[0008] The rubber airbag sealing strip is installed in the gap between the screen frame and the LED screen. The inner bottom surface of the screen frame is provided with a rubber airbag bag. The rubber airbag sealing strip is fixedly installed on the inner wall of the screen frame and distributed around the inner wall of the screen frame. The rubber airbag sealing strip and the rubber airbag bag are connected by an air tube.

[0009] When the LED screen is installed and snapped into the screen frame, the LED screen compresses the rubber airbag. The gas in the rubber airbag enters the rubber airbag sealing strip through the air tube. The rubber airbag sealing strip expands and seals between the screen frame and the LED screen.

[0010] Preferably, the inner bottom surface of the screen frame is provided with a slot, and a card plate is fixedly installed on the back of the LED screen. When the LED screen is snapped into the screen frame, the slot and the card plate engage with each other.

[0011] Preferably, the card plate is provided with positioning holes, one side of the card slot is provided with a telescopic groove, and the other side is provided with a control groove. A pin is slidably arranged in the telescopic groove. One end of the pin has an arc surface, and the other end of the pin is fixedly provided with a spring. The end of the spring away from the pin is fixedly connected to the bottom surface of the telescopic groove.

[0012] Preferably, a control rod is movably disposed in the control slot, extending through the outside of the screen frame. A second magnet is fixedly disposed at one end of the control rod near the pin, and a first magnet is fixedly disposed at the inside of the pin away from the spring. The first magnet and the second magnet repel each other and move away from each other.

[0013] Preferably, an elastic sleeve is fixedly provided at one end of the control lever that extends through the outside of the screen frame.

[0014] Preferably, a humidity sensor is provided between the screen frame and the LED screen.

[0015] Preferably, a suction pump is fixedly installed on the back of the screen frame. The suction pump is provided with an air outlet channel and an air outlet main pipe. The air outlet channel is connected to the gap between the screen frame and the LED screen. The end of the air outlet main pipe is provided with a first auxiliary pipe and a second auxiliary pipe. The second auxiliary pipe is connected to the outside of the screen frame, and the first auxiliary pipe is connected to the corresponding rubber airbag. Solenoid valves are provided on both the first auxiliary pipe and the second auxiliary pipe.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] Because the rubber airbag sealing strip gradually expands and enlarges during the process of the LED screen being snapped into the screen frame to achieve a seal, it not only facilitates the smooth installation of the LED screen, but also ensures that the rubber airbag sealing strip can better seal the gap between the LED screen and the screen frame without the need for subsequent glue injection. The sealing structure is simple, but it takes into account both the ease of installation of the LED screen and the waterproof effect.

[0018] During operation, the higher the heat, the greater the gas pressure inside the rubber airbag sealing strip, resulting in a better sealing effect.

[0019] When the suction pump is turned on, the moisture in the gap between the screen frame and the LED screen can be extracted to avoid excessive humidity affecting the use. At the same time, if the solenoid valve on the first auxiliary pipe is turned on, this part of the air can be pumped into the rubber airbag and the rubber airbag sealing strip, thereby increasing the sealing effect of the gap between the screen frame and the LED screen.

[0031] This utility model provides, for example Figures 1-8 The diagram shows a waterproof mechanism for an outdoor LED screen. This waterproof mechanism has a simple structure and can be used with the LED screen 2 to effectively seal the gap between the screen frame 1 and the LED screen 2.

[0032] refer to Figure 1 and Figure 2 As shown, the screen frame 1 is a rectangular box structure. A rubber airbag 4 is installed on the bottom inner surface of the screen frame 1. A rubber airbag sealing strip 3 is fixedly installed on the inner wall of the screen frame 1 and distributed around its circumference. The rubber airbag sealing strip 3 and the rubber airbag 4 are connected by an air pipe 5. When the LED screen 2 is installed and snapped into the screen frame 1, the LED screen 2 can compress the rubber airbag 4, allowing the gas in the rubber airbag 4 to enter the rubber airbag sealing strip 3 through the air pipe 5. The rubber airbag sealing strip 3 expands, effectively sealing the area between the screen frame 1 and the LED screen 2, achieving a waterproof effect. Simultaneously, during operation, the higher the heat, the greater the gas pressure inside the rubber airbag sealing strip 3, resulting in a better sealing effect.

[0033] As the rubber airbag sealing strip 3 gradually expands and enlarges during the process of the LED screen 2 being snapped into the screen frame 1 to achieve a seal, it not only facilitates the smooth installation of the LED screen 2, but also ensures that the rubber airbag sealing strip 3 can better seal the gap between the LED screen 2 and the screen frame 1 without the need for subsequent glue injection. The sealing structure is simple, but it takes into account both the ease of installation of the LED screen 2 and the waterproof effect.

[0034] refer to Figure 2 and Figure 3 As shown, a slot 6 is provided on the bottom inner surface of the screen frame 1, and a card plate 7 is fixedly installed on the back of the LED screen 2. When the LED screen 2 is snapped into the screen frame 1, the slot 6 and the card plate 7 engage with each other, which can realize the quick fixation between the screen frame 1 and the LED screen 2.

[0035] Specifically: See reference Figures 4 to 8 As shown, a positioning hole 8 is provided on the card plate 7, a telescopic groove 12 is provided on one side of the card slot 6, and a control groove 10 is provided on the other side. A pin 9 is slidably arranged in the telescopic groove 12. One end of the pin 9 has an arc surface 14, and the other end of the pin 9 is fixedly provided with a spring 13. The end of the spring 13 away from the pin 9 is fixedly connected to the bottom surface of the telescopic groove 12. When the LED screen 2 is engaged into the screen frame 1, the card plate 7 abuts against the arc surface 14, causing the pin 9 to retract into the telescopic groove 12. When the card plate 7 extends into the designated position inside the card slot 6, the end of the pin 9 loses the abutment of the card plate 7 and extends into the positioning hole 8, thereby engaging and fixing the card plate 7, completing the relative fixation of the screen frame 1 and the LED screen 2.

[0036] Furthermore, a control lever 11 is movably disposed in the control groove 10, extending through the outside of the screen frame 1. A second magnet 16 is fixedly disposed at one end of the control lever 11 near the pin 9, and a first magnet 15 is fixedly disposed at the end of the pin 9 away from the spring 13. The first magnet 15 and the second magnet 16 repel each other and move away from each other. When it is necessary to disassemble the LED screen 2, the control lever 11 can be pushed to bring the first magnet 15 and the second magnet 16 closer together. The pin 9 can retract into the telescopic groove 12 by utilizing the repulsive effect between the first magnet 15 and the second magnet 16. At this time, the LED screen 2 can be smoothly removed from the screen frame 1.

[0037] It should be noted that an elastic sleeve 17 is fixedly installed at one end of the control lever 11 that extends through the outside of the screen frame 1. The elastic sleeve 17 serves both aesthetic purposes and allows the elastic force of the sleeve 17 itself to drive the control lever 11 to reset, thereby enabling the second magnet 16 to reset. Example 2

[0038] This utility model provides, for example Figures 9 to 10 The waterproof mechanism of an outdoor LED screen shown includes a humidity sensor 18 installed between the screen frame 1 and the LED screen 2. The humidity sensor 18 can monitor the humidity in the gap between the screen frame 1 and the LED screen 2. When the humidity is high, it will not only affect the service life of the components on the back of the LED screen 2, but may also be due to water leakage in the gap between the screen frame 1 and the LED screen 2.

[0039] A suction pump 19 is fixedly installed on the back of the screen frame 1. The suction pump 19 is provided with an air outlet channel 20 and an air outlet main pipe 21. The air outlet channel 20 is connected to the gap between the screen frame 1 and the LED screen 2. The end of the air outlet main pipe 21 is provided with a first auxiliary pipe 22 and a second auxiliary pipe 23. The second auxiliary pipe 23 is connected to the outside of the screen frame 1. The first auxiliary pipe 22 is connected to the corresponding rubber airbag 4. Solenoid valves 24 are provided on both the first auxiliary pipe 22 and the second auxiliary pipe 23. When the suction pump 19 is turned on, the moisture in the gap between the screen frame 1 and the LED screen 2 can be extracted to avoid excessive humidity affecting the use. At the same time, if the solenoid valve 24 on the first auxiliary pipe 22 is turned on, this part of the air can be pumped into the rubber airbag 4 and the rubber airbag sealing strip 3, thereby increasing the sealing effect of the gap between the screen frame 1 and the LED screen 2.
