[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a marking spraying device for rail transit vehicles, including a spray gun 1, an upper arc-shaped seat 8, and a hexagonal assembly plate 7. A mounting cover 2 is fixedly installed at the bottom of the spray gun 1, and a paint tank 3 is fitted inside the mounting cover 2. A bent connecting rod 13 is fixedly installed on one side of the spray gun 1. A pressing handle 14 is fixedly installed at the end of the bent connecting rod 13 away from the spray gun 1. A connecting block 4 is fixedly installed at the end of the pressing handle 14 away from the bent connecting rod 13. A lower arc-shaped seat 6 is fixedly installed on the top of the connecting block 4. An arc-shaped assembly groove 16 is formed on the top of the lower arc-shaped seat 6. An assembly circular plate 15 is fixedly installed at the bottom of the upper arc-shaped seat 8. The round plate 15 has a hexagonal through groove 10 inside, and a hexagonal assembly groove 9 is provided on one side of the round plate 15. The hexagonal assembly plate 7 has a marking groove 5 inside. The outer contour of the round plate 15 is matched with the inner contour of the arc-shaped assembly groove 16. The round plate 15 is snapped into the arc-shaped assembly groove 16. The inner contour of the hexagonal assembly groove 9 is matched with the outer contour of the hexagonal assembly plate 7. The hexagonal assembly plate 7 is snapped into the hexagonal assembly groove 9. The position of the marking groove 5 corresponds to the position of the hexagonal through groove 10. There are multiple hexagonal assembly plates 7, and the shape of the marking groove 5 inside the multiple hexagonal assembly plates 7 is different.

[0020] The working principle of the above technical solution is as follows: A suitable hexagonal assembly plate 7 for the marking groove 5 can be selected according to requirements. Simply pull the upper arc-shaped seat 8 upwards to detach the assembly round plate 15 from the inside of the arc-shaped assembly groove 16 at the top of the lower arc-shaped seat 6. Then, the hexagonal assembly plate 7 can be snapped into the inside of the hexagonal assembly groove 9. Finally, the assembly round plate 15 is snapped back into the arc-shaped assembly groove 16 at the top of the lower arc-shaped seat 6, thus aligning the marking groove 5 with the spraying end of the spray gun 1. A suitable marking groove 5 can be flexibly selected according to different specific needs to perform precise and efficient spraying operations. The configuration and parameters of the marking slot 5 are adjusted to meet various complex and fine spraying requirements, making it widely applicable. It not only improves work efficiency but also ensures spraying quality and aesthetics. Then, one side of the lower arc-shaped seat 6 and the upper arc-shaped seat 8 are aligned with the outer side of the area to be sprayed on the vehicle, and the marking slot 5 is aligned with the area to be sprayed. Then, the paint inside the paint tank 3 installed inside the mounting cover 2 is pumped out by the spray gun 1, so that the marking on the outside of the vehicle is the same as the marking slot 5. Spraying is convenient and simple, and it is easy to carry. A single person can complete the spraying task, improving the effectiveness of the device.

[0021] In another implementation scheme, such as Figures 1-4 As shown, a splash guard 11 is installed on the spraying end of the spray gun 1. The end of the splash guard 11 away from the spray gun 1 is in contact with one side of the hexagonal assembly plate 7. The splash guard 11 covers the outside of the marking groove 5. A snap-fit ​​sleeve 12 is fixedly installed on one end of the splash guard 11. The spraying end of the spray gun 1 is snap-fitted and installed on the inside of the snap-fit ​​sleeve 12.

[0022] The splash guard 11 can be installed on the outside of the spraying end of the spray gun 1 by means of the snap-fit ​​sleeve 12, thereby preventing paint from splashing during spraying.

[0023] Working principle: The appropriate hexagonal assembly plate 7 for the marking slot 5 can be selected according to requirements. Simply pull the upper arc-shaped seat 8 upwards to detach the assembly round plate 15 from the inside of the arc-shaped assembly slot 16 at the top of the lower arc-shaped seat 6. Then, the hexagonal assembly plate 7 can be snapped into the inside of the hexagonal assembly slot 9. Finally, the assembly round plate 15 is snapped back into the arc-shaped assembly slot 16 at the top of the lower arc-shaped seat 6, thus aligning the marking slot 5 with the spraying end of the spray gun 1. The appropriate marking slot 5 can be flexibly selected according to different specific needs for precise and efficient spraying operations. By precisely adjusting the configuration and parameters of the marking slot 5, various complex and fine spraying requirements can be met. The coating requirements are met, and the application range is wide. It not only improves work efficiency but also ensures the quality and aesthetics of the coating. Then, one side of the lower arc-shaped seat 6 and the upper arc-shaped seat 8 are attached to the outside of the area to be coated on the vehicle, and the marking groove 5 is aligned with the area to be coated. Then, the paint inside the paint tank 3 installed inside the mounting cover 2 is pumped out by the spray gun 1, so that the marking on the outside of the vehicle is the same as the marking groove 5. The coating is convenient and simple, easy to carry, and a single person can complete the coating task, improving the use effect of the device. The splash guard 11 can be installed on the outside of the spraying end of the spray gun 1 through the snap-fit ​​sleeve 12 to prevent paint from splashing during spraying.
