[0002] With the development of urban subways and intercity railways, the passenger flow in stations is increasing day by day, and there are higher demands for the utilization rate of limited station space, equipment safety, and overall aesthetics. This places higher requirements on the LED displays of subways and intercity railways.
[0003] Traditional LED displays are fixed with thick metal frames around their perimeter, resulting in visual seams that are neither aesthetically pleasing nor stylish. This also increases the weight of the LED display equipment, as the hanging mounting components have a heavy load-bearing capacity, leading to frequent maintenance and repairs during later use, and low space utilization. Utility Model Content
[0004] This utility model provides a hanging frameless LED display fixing device for a railway passenger service system. The fixing frame of the display screen is hidden behind the display screen module. Compared with traditional display screens, this utility model has a frameless structure on all four sides, which is stylish and beautiful, seamlessly spliced, efficient in installation, space-saving, highly versatile, and convenient in operation and maintenance, thus achieving good economic and social benefits.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A hanging frameless LED display fixing device for a railway passenger service system includes a rectangular frame for fixing several LED displays and two hanging rods. Several support rods are set inside the rectangular frame, and the two ends of the support rods are respectively fixed to a set of long sides of the rectangular frame. Four triangular fixing plates are fixedly connected to the four corners of the inner side of the rectangular frame. Two hanging rods are fixedly connected to the outer side of one long side of the rectangular frame, and the other ends of the two hanging rods are installed on the wall.
[0007] Furthermore, there are no fewer than two support rods, and all support rods are distributed parallel to the short side of the rectangular frame.
[0008] Furthermore, both the long and short sides of the rectangular frame are integer multiples of the side length of the LED display screen.
[0009] Furthermore, two symmetrically distributed fall arrest rope fasteners are provided on the inner side of the rectangular frame, and the fall arrest rope fasteners and the hanging rod are coaxial in the vertical direction.
[0010] Furthermore, the rectangular frame, hanging rods, support rods, fall arrest rope fasteners, and triangular fixing plates are all coated with anti-rust coatings.
[0011] Furthermore, the length of the right-angled side of the triangular fixing plate is less than the distance between the short side of the rectangular frame and the adjacent support rod.
[0012] Furthermore, a protective layer is installed on the outside of the rectangular frame.
[0013] In summary, the beneficial effects of this utility model are:
[0014] This invention improves the mounting frame structure of LED displays by hiding the fixing device behind the display, thus reducing the size of the display and creating a frameless LED display. This increases the space available for installing other equipment. The size of the rectangular frame can be adjusted according to the size and number of different displays, reducing construction difficulty and making the installation of the display simpler, faster, and with a high success rate. This saves labor and time costs, improves construction efficiency, and reduces construction costs. At the same time, it facilitates later operation, maintenance, and repair, greatly reducing operating and maintenance costs. The perfect integration of the display module and the rectangular frame improves space utilization, enhances the overall visual aesthetics, and ensures that the display module fits snugly against the rectangular frame, also solving the problem of uneven screen surfaces.

[0020] like Figures 1-2 As shown, this utility model discloses a hanging frameless LED display fixing device for a railway passenger service system, including a rectangular frame 2 for fixing several LED displays and two hanging rods. Several support rods 3 are arranged inside the rectangular frame 2, with both ends of each support rod 3 fixed to a set of long sides of the rectangular frame 2. The number of support rods 3 is not less than two, and all support rods 3 are distributed parallel to the short sides of the rectangular frame 2. When multiple LED display modules are used, the LED display modules inside the rectangular frame 2 can be fixed using the support rods 3. Figure 1In the illustrated embodiment, there are five support rods 3, which are distributed parallel and equidistantly between a set of short sides of the rectangular frame 2. Four triangular fixing plates 1 are fixedly connected at the four corners of the inner side of the rectangular frame 2 to ensure the stability of the rectangular frame 2. The right-angled side length of the triangular fixing plate 1 is less than the distance between the short side of the rectangular frame 2 and the adjacent support rod 3. The long side and short side of the rectangular frame 2 are both integer multiples of the side length of the LED display screen. In actual use, the size of the rectangular frame 2 can be adjusted according to specific needs, i.e., the number of display screens. Two hanging rods are fixedly connected to the outer side of one long side of the rectangular frame 2, and the other ends of the two hanging rods are installed on the wall. Two symmetrically distributed anti-fall rope fixing parts 4 are provided on the inner side of the rectangular frame 2. The anti-fall rope fixing parts 4 and the hanging rods are coaxial in the vertical direction. A protective layer is provided on the outer side of the rectangular frame 2.
[0021] The rectangular frame 2, the hanging rod, the support rod 3, the fall arrest rope fixing part 4, and the triangular fixing plate 1 are all equipped with anti-rust coating.

[0023] In this embodiment, the LED display module is 320mm long, 160mm wide, and 25mm thick. A rectangular frame can be made according to the specific site conditions, and the flatness can be adjusted by using magnetic bolts to enter the bolt holes and adjust the number of threads.
[0024] Taking 30 LED display modules as an example, with a display screen length of 1920mm and a width of 800mm, the manufacturing steps of this utility model are as follows:
[0025] Two 1920×100×40mm square steel bars and two 792×100×40mm square steel bars are selected and welded into a rectangular frame. The outside is then wrapped with a 160mm wide sheet metal as a protective layer. Ten 792×40×40mm square steel bars are evenly welded to both sides of the rectangular frame and parallel to the short side of the rectangular frame. Four isosceles triangular iron plates with a side length of 80×80mm are welded to the four right angles on the inside of the rectangular frame. The LED display module is fixed inside the rectangular frame 2 of this utility model. The frameless LED display is then hoisted onto the roof using a hanger.
