Description

Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to a sealing component for an outdoor LCD screen with dustproof and waterproof functions. Background Technology

[0002] Outdoor LCD displays are high-brightness, high-definition display devices specifically designed for outdoor environments. Ordinary LCD screens have a brightness range of 100 to 500 nits, which cannot be clearly displayed outdoors. However, outdoor high-brightness LCD screens, by increasing the LED backlight, can typically reach a brightness of 800 to 1000 nits or even higher, enabling clear display of images in sunlight without color distortion.

[0003] By enhancing the LED backlight of the LCD screen module, the brightness of the backlight source is increased to be comparable to or even higher than that of natural outdoor light, thereby achieving high-definition outdoor displays. These displays are widely used in outdoor advertising, traffic signs, stadiums, stations, shopping malls, and other places, such as electronic bus stop signs, advertising screens on the exterior walls of shopping malls, and guide screens in scenic spots, providing people with a high-quality visual experience and information dissemination services.

[0004] The above-mentioned device has the following defects: the display screen will generate heat during long-term operation, which will seriously reduce its service life. Therefore, it is necessary to open through holes in the sealing component to allow air circulation and heat dissipation. However, the exposed holes will allow rainwater and dust to enter, making the inside of the display screen susceptible to moisture or corrosion from dust and impurities. To solve the above problems, an outdoor LCD liquid crystal display sealing component with dustproof and waterproof functions is proposed. Utility Model Content

It aims to improve the problem in the prior art that the sealing component needs to have through holes to allow air circulation and heat dissipation, but the exposed holes allow rainwater and dust to enter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor LCD screen sealing assembly with dustproof and waterproof functions, comprising a screen body, a sealing housing, and a fan body. The sealing housing is fixedly connected to the rear outer wall of the screen body, and the fan body is fixedly connected to the rear inner wall of the sealing housing. Side plates are fixedly installed on the left and right outer walls of the sealing housing, and through holes are opened on the left and right outer walls of the sealing housing. An auxiliary mechanism is provided on the side plate, and an adjustment mechanism is provided on the sealing housing. The auxiliary mechanism includes an inlet and outlet, which are opened on the bottom inner wall of the side plate. Air bends are opened on the left and right inner walls of the side plate. An installation groove is opened on the bottom inner wall of the side plate, and a filter screen is slidably connected to the bottom inner wall of the installation groove. A first lever is slidably connected to the front inner wall of the side plate, and an insert plate is fixedly connected to the bottom outer wall of the first lever. A compression spring is fixedly connected to the top outer wall of the first lever. A second lever is slidably connected to the front inner wall of the side plate, and a locking plate is fixedly connected to the top outer wall of the second lever.

[0007] As a further description of the above technical solution: the adjustment mechanism includes a base frame, which is fixedly connected to the bottom outer wall of the sealing component housing. A universal pulley is fixedly connected to the bottom outer wall of the base frame. A hand support is slidably connected to the rear inner wall of the sealing component housing. A sliding plate is slidably connected to the top inner wall of the hand support. A limit plate is fixedly connected to the left outer wall of the sliding plate. A telescopic spring is fixedly connected to the right outer wall of the sliding plate. A frosted plate is fixedly connected to the bottom outer wall of the hand support.

[0008] As a further description of the above technical solution: the air bend is connected to the inlet and outlet, and the air bend is connected to the through hole.

[0009] As a further description of the above technical solution: the insert plate is snapped onto the top inner wall of the filter screen plate, and the end of the compression spring away from the first deflector is fixedly connected to the bottom outer wall of the second deflector.

[0010] As a further description of the above technical solution: wear-resistant sleeves are fixedly connected to the outer side walls of both the card plate and the insert plate, and the card plate is snapped into the inner walls of the left and right sides of the sealing housing.

[0011] As a further description of the above technical solution: the hand support extends through the bottom inner wall of the base frame, and silicone pads are fixedly connected to the left and right outer walls of the sliding plate.

[0012] As a further description of the above technical solution: the limiting plate is snapped onto the left inner wall of the sealing housing, and the end of the telescopic spring away from the sliding plate is fixedly connected to the right inner wall of the hand support.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the air bend design of the auxiliary mechanism allows outside air to enter and bend, diluting moisture. Combined with the silicone layer, this further ensures the air entering the sealed housing remains dry, effectively preventing moisture intrusion and damage to the display screen body. Simultaneously, the filter screen intercepts impurities and insects, preventing them from entering the interior through the through-holes and causing contamination. After long-term use, the filter screen can be easily removed for replacement and maintenance, ensuring continuous and stable dustproof performance. Furthermore, the through-holes, in conjunction with the fan body, achieve air circulation, providing a dry environment for the display screen body and promptly expelling hot air from the interior, thus achieving heat dissipation and further ensuring stable operation of the display screen body in outdoor environments.

[0015] 2. In this utility model, the main body of the display screen can be easily moved to meet the adjustment needs of different outdoor usage positions. When fixing is required, the upper handle bracket moves the frosted plate upward, and then the sliding plate adjusts the engagement state between the limiting plate and the sealing housing, so that the frosted plate contacts the ground to limit the universal pulley, achieving stable fixing. The operation is simple and efficient. This convenient adjustment method of movement and fixing greatly improves the flexibility of the display screen when used outdoors, and the position adjustment and fixing can be completed without the need for additional tools, reducing the difficulty of operation when used outdoors.

The side plates 5 are provided with auxiliary... The auxiliary mechanism 6 has an adjustment mechanism 7 on the sealing housing 2. The auxiliary mechanism 6 includes an inlet / outlet 61, which is located on the bottom inner wall of the side plate 5. Air bends 62 are provided on the left and right inner walls of the side plate 5. An installation groove 63 is provided on the bottom inner wall of the side plate 5. The installation groove 63 provides installation space for the filter screen plate 64, facilitating the placement and removal of the filter screen plate 64. The filter screen plate 64 is slidably connected to the bottom inner wall of the installation groove 63. A first lever 65 is slidably connected to the front inner wall of the side plate 5. An insert plate 66 is fixedly connected to the bottom outer wall of the first lever 65. A compression spring 67 is fixedly connected to the top outer wall of the first lever 65. A second lever 68 is slidably connected to the front inner wall of the side plate 5. A locking plate 69 is fixedly connected to the top outer wall of the second lever 68.

[0024] Reference Figures 2-4The air bend 62 is connected to the inlet / outlet 61 and the through hole 4. A silicone layer is fixedly connected to the inner wall of the air bend 62. The silicone layer allows the dry air after dehumidification through the air bend 62 to enter the interior of the sealing housing 2 through the through hole 4, providing a dry air environment for the display screen body 1 and realizing air circulation and heat dissipation. The insert plate 66 is snapped onto the top inner wall of the filter plate 64.

Wear-resistant sleeves are fixedly connected to the side outer walls of the clamping plate 69 and the insert plate 66. The wear-resistant sleeves can reduce the frictional wear between the clamping plate 69 and the inner wall of the sealing housing 2, and between the insert plate 66 and the inner wall of the filter plate 64, extend the service life of the components, and enhance the tightness of the snapping and improve the fixing effect. The clamping plate 69 is snapped onto the inner walls of the left and right sides of the sealing housing 2.

[0025] Reference Figures 3-4 The adjustment mechanism 7 includes a base frame 71, which is fixedly connected to the bottom outer wall of the sealing housing 2.

The end of the telescopic spring 76 away from the sliding plate 74 is fixedly connected to the right inner wall of the hand support 73.

[0026] Working principle: Outside air is drawn into the inlet / outlet 61 by the fan body 3. The air then passes through the air bend 62, where air collision occurs, diluting the moisture in the air and allowing dry air to enter the through hole 4. This facilitates air circulation between the display body 1 and the sealing housing 2. Hot air is discharged through another through hole 4. Simultaneously, the air is filtered by the filter plate 64 as it is drawn into the inlet / outlet 61, preventing impurities and insects from entering. For long-term use, pulling the first lever 65 moves the insert plate 66 upward, separating it from the filter plate 64. The filter plate 64 can then be easily removed from the mounting slot 63 for replacement and maintenance. When the display body 1 needs to be moved outdoors for adjustment, the upper handle bracket 73 moves the frosted plate 77 upward, allowing the universal pulley 72 to move the display body 1 easily. Then, pulling the sliding plate 74 moves the limiting plate 75, separating it from the inner wall of the sealing housing 2. The frosted plate 77 then contacts the ground and limits the universal pulley 72.
