[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the utility model provides a foldable advertising screen structure for a bus, comprising: a fixed bracket 10, a mounting bracket 20, a buckle 30, a spring 40 and a supporting bracket 50; the fixed bracket 10 is placed horizontally, and a placement station is formed on the upper part; the mounting bracket 20 can be rotated in the placement station of the fixed bracket 10 along the vertical direction, and a vertical slide groove is provided on the mounting bracket 20, and a mounting surface for connecting the advertising screen is formed on one side of the mounting bracket 20; the buckle 30 can be rotated on the mounting bracket 20 and is located in the slide groove; the spring 40 is installed on the buckle 30, one end of the spring 40 contacts the buckle 30, and the other end contacts the mounting bracket 20; one end of the supporting bracket 50 is rotatably connected to the fixed bracket 10, and the other end can slide in the slide groove, and one end of the supporting bracket 50 located in the slide groove is locked in the slide groove through the buckle 30 to compress the spring 40. The fixed bracket 10 is connected to the bus. The mounting bracket 20 plays a role in bearing and supporting the advertising screen, which facilitates the placement and installation of the advertising screen. When the supporting bracket 50 is tilted, the fixing bracket 10, the mounting bracket 20 and the supporting bracket 50 form a triangular structure, and the triangle has stability.

[0024] By setting the fixing bracket 10, the mounting bracket 20, the buckle 30, the spring 40 and the supporting bracket 50, the advertising screen is installed on one side of the mounting bracket 20. When the mounting bracket 20 needs to be in a vertical state, by pressing the buckle 30, the supporting bracket 50 slides upward to rotate the mounting bracket 20. When the top end of the supporting bracket 50 slides to the bottom of the slide groove on the mounting bracket 20, the supporting bracket 50 is located below the buckle 30, and the bottom end of the buckle 30 will resist the supporting bracket 50, ensuring that the mounting bracket 20 is stable in the vertical state. By pressing the buckle 30, the spring 40 is compressed, and the top end of the supporting bracket 50 slides above the buckle 30, and the mounting bracket 20 and the supporting bracket 50 are placed on 10, so that the advertising screen on one side of the mounting bracket 20 can be switched between a stable vertical state and a laid down state. The foldable advertising screen structure for the bus can be folded and laid down in an emergency, so that people can escape from the rear window, and the advertising screen is easy to fold.

[0025] The fixing bracket 10 , the mounting bracket 20 and the supporting bracket 50 are made of stainless steel.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the foldable advertising screen structure for buses also includes a first pin shaft 60, a second pin shaft 70, a third pin shaft 80 and a fourth pin shaft 90. The mounting bracket 20 is rotatably connected to the fixed bracket 10 via the first pin shaft 60; the buckle 30 and the spring 40 are rotatably connected to the mounting bracket 20 via the second pin shaft 70; the third pin shaft 80 is movable in the slide groove of the mounting bracket 20, and the supporting bracket 50 is connected to the third pin shaft 80; the end of the supporting bracket 50 away from the third pin shaft 80 is rotatably connected to the fixed bracket 10 via the fourth pin shaft 90.

[0027] The setting of the first pin shaft 60 facilitates the rotation of the mounting bracket 20 on the fixed bracket 10, the setting of the second pin shaft 70 facilitates the rotation of the buckle 30 and the spring 40 on the mounting bracket 20, the setting of the third pin shaft 80 facilitates the movement of the supporting bracket 50 on the slide groove, and the slide groove serves to limit the end of the supporting bracket 50, and the setting of the fourth pin shaft 90 facilitates the rotation of the bottom end of the supporting bracket 50 on the fixed bracket 10.

[0028] like Figure 4 , Figure 6 As shown, in this embodiment, the spring 40 is a torsion spring, and the second pin 70 passes through the torsion spring.
