Technical Field

[0001] The utility model relates to the field of waterproof display screens, in particular to a double-sided waterproof outdoor display screen. Background Art

[0002] Existing outdoor display screens are inevitably frequently exposed to rain due to long-term exposure to the natural environment. However, the waterproof design of most display screens is currently mainly concentrated on the front, and a sealed door is usually installed on the back for easy maintenance. This sealed door is generally installed on the display screen cabinet through a hinge. Although such a design is easy to open and close, its sealing effect is not satisfactory. Especially in heavy rainfall, rainwater is likely to penetrate into the cabinet through the tiny gap between the sealed door and the cabinet, causing potential damage to the circuits and components of the display screen.

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figures 1 to 3A double-sided waterproof outdoor display screen is mainly composed of a box body 1. A grid frame 2 is installed on the front of the box body 1. A plurality of mounting grooves 4 are carefully arranged on the grid frame 2. These mounting grooves 4 are specially designed for mounting display modules 3. In order to ensure the waterproof performance of the display screen, a first waterproof pad 5 is cleverly placed in the mounting groove 4, especially at the connection between the grid frame 2 and the display module 3.

[0023] A U-shaped frame 6 is provided at the back edge of the steering box 1, and a slide groove 7 is specially provided on the inner side of the frame 6. A slidable sealing door 8 is designed in the slide groove 7. In order to further enhance the waterproof effect, a second waterproof pad 9 is also provided in the slide groove 7. It is worth mentioning that a special extrusion component 10 is installed inside the sealing door 8, which can effectively squeeze the second waterproof pad 9 to ensure that it fits tightly, thereby achieving a waterproof effect.

[0024] Please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, a receiving groove 11 is provided on one side of the sealing door 8, and the extrusion assembly 10 includes a pressing plate 12 that can slide freely in the receiving groove 11. When the pressing plate 12 slides, it will fit tightly with the second waterproof pad 9. One side of the pressing plate 12 is connected to the threaded rod 13, and the side of the pressing plate 12 away from the box body 1 is a structure with a central convexity, and a connecting hole for rotatably connecting the threaded rod 1 is provided in the middle, so that the strength of the pressing plate 12 is good, and the extrusion force of the threaded rod 13 on the pressing plate 12 can be better transmitted to the four sides of the pressing plate 12 so as to form a stable sealing fit with the second waterproof pad 9.

[0025] The threaded rod 13 is tightly connected to the sealing door 8 through threads. For easy operation, a hexagon socket screw head 14 is fixed to one end of the threaded rod 13 located outside the sealing door 8. When the hexagon socket screw head 14 is turned with a wrench, the threaded rod 13 will turn accordingly, thereby driving the pressing plate 12 to slide along the receiving groove 11, effectively squeezing the second waterproof pad 9 to ensure the sealing of the back of the box body 1.

[0026] In addition, our mounting groove 4 is designed to be stepped, and to match it, a special matching portion 15 is also provided on the display module 3. This design not only has a good matching effect, but also greatly facilitates installation and positioning. The edge of each display module 3 is in close contact with the adjacent module, ensuring that there is no gap in the display screen, bringing users a more coherent and smooth viewing experience.

[0027] In order to ensure the stability of the waterproof pad, we use glue to firmly bond the second waterproof pad 9 to the slide groove 7, and the first waterproof pad 5 to the mounting groove 4. This fixing method works very well and can effectively prevent moisture from penetrating.

[0028] In order to facilitate user operation, a handle 16 is specially installed on the sealed door 8, so that you can easily drive the sealed door 8 to slide along the slide 7. It is worth mentioning that at least three of these handles 16 are set, and they are evenly distributed, which means that no matter where you stand, you can easily operate the sealed door 8.

[0029] Overall, the design of the box body 1 is square, which is not only beautiful, but also perfectly matches the shape of the display module 3. The mounting slots 4 are distributed in an array, and the number of mounting slots 4 in each row and column is greater than or equal to 2. This design enables the display screen to adapt to a larger display range and meet the needs of various occasions.

[0030] It is particularly worth mentioning that when the length of the slide groove 7 is completely equal to the length of the pressing plate 12, the pressing plate 12 will not protrude from the U-shaped frame 6. Such a design is both beautiful and practical, ensuring the compactness and stability of the overall structure.

[0031] Working principle:

[0032] Display screen structure: The display screen is composed of a box 1, a grid frame 2, a display module 3 and other components. The mounting slot 4 on the grid frame 2 is used to install the display module 3. Each module matches the matching portion 15 of the mounting slot 4 during installation to ensure a stable installation.

[0033] Waterproof design: In order to improve the waterproof performance of the display screen, a first waterproof pad 5 is installed at the connection between the grid frame 2 and the display module 3 in the installation groove 4. This can effectively prevent moisture from penetrating into the interior of the display screen through these connections.

[0034] Sealed door mechanism: The back of the box 1 is provided with a U-shaped frame 6, with a slide groove 7 inside, and a sealed door 8 is slidably connected in the slide groove 7. This design allows easy access to the inside of the display for maintenance or adjustment. In order to further enhance the waterproof effect, a second waterproof pad 9 is installed in the slide groove 7.

[0035] Extrusion assembly: An extrusion assembly 10 is provided inside the sealing door 8, including a pressing plate 12 and a threaded rod 13. When the sealing door 8 is closed, the pressing plate 12 can be moved by rotating the threaded rod 13, thereby squeezing the second waterproof pad 9 to ensure a close fit between the sealing door 8 and the box body 1 to prevent moisture penetration.

[0036] Convenient operation: The handle 16 installed on the sealing door 8 is convenient for the staff to open and close the sealing door. At the same time, the hexagonal screw head 14 at the end of the threaded rod 13 is convenient for adjustment using tools.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
