[0002] During the decoration process, some personalized wall designs, such as some panel paintings and special decorative panels pasted on the wall, will be sprayed with protective paint to prevent them from fading due to direct exposure to the air after completion. The most common spraying method is with a spray pen.
[0003] In the current spraying process, most of the workers directly hold the spray gun to spray the protective paint on the board. This method has certain disadvantages. For example, the stability of the spray gun cannot be maintained for a long time by holding it, which leads to uneven spraying, resulting in paint stuck on the surface of the board, affecting the appearance. At the same time, the board needs to be cleaned before spraying before the protective paint can be sprayed. However, in the decoration site, a certain amount of dust will be generated. Once the dust adheres to the board, it will cause the dust to be wrapped by the protective paint, affecting the quality of the wall design.
[0004] Therefore, it is necessary to provide a new special spraying equipment for decoration to solve the above-mentioned technical problems. Utility Model Content

The four limiting rods respectively penetrate through the two sliding plates 10 and are slidably connected therewith.
[0026] The working principle of the special spraying device for decoration provided by the present utility model is as follows:
[0027] When it is necessary to spray protective paint on the surface of the decorative board, the staff can first hold the spray pen 1 and inject paint into the spray pen 1, and then aim the spray pen 1 at the spraying area. At this time, the cleaning roller 5 will first contact the surface of the board, and then after continuously pressing the spray pen 1, the paint outlet of the spray pen 1 will be close to the board. At the same time, due to the pressure, the rotating plate 4 will rotate along the curved rod 15, thereby gradually compressing the curved spring 17, so that the curved spring 17 is in a compressed energy storage state. Under the reaction effect of the curved spring 17, the cleaning roller 5 will always maintain a state of close fit with the surface of the board.
[0028] After determining the distance between the paint outlet of the spray pen 1 and the plate, the staff can insert the pin rod 22 on the support plate 23 so that the bottom end of the pin rod 22 is inserted into the corresponding embedding hole 21, thereby realizing the positioning of the rotating plate 4. At this time, the staff can start the spray pen 1 to spray the protective paint. Through the above operation, when the staff is spraying, the cleaning roller 5 will clean the plate in front, thereby preventing the appearance of debris on the plate.
[0029] When the work is completed and it is time to store, the staff can press the two hand buttons 14 to make the two hand buttons 14 approach each other, thereby driving the two sliding plates 10 to approach each other, and then the two positioning columns 11 move toward the chamber 9, and finally move out of the two positioning holes 7 respectively. At this time, the external frame 3 can be removed from the fixing ring 2, and when storing, it can be separated into two parts, the airbrush 1 and the external frame 3, so that no space is taken up.
[0030] Compared with the related art, the decoration-specific spraying equipment provided by the utility model has the following beneficial effects:
[0031] The utility model provides a special spraying device for decoration. The cleaning roller 5 can always keep in contact with the surface of the plate through the cooperation of the rotating plate 4 and the curved spring 17, so as to clean the front of the spraying path and prevent foreign matter from being wrapped in the protective paint. At the same time, after the rotating plate 4 is limited, when the staff keeps the spray pen 1 vertical to the plate, the support of the cleaning roller 5 and the rotating plate 4 can keep the staff's wrist in a stable state, so that the spraying of the protective paint is more uniform, which improves the quality of the protective paint spraying to a certain extent.
