Its composition not only includes the light source but also all the components required for fixing and protecting the light source and the line accessories connected to the power supply. As an important part of the lighting fixture, the treatment method and material selection of the outer wall of the fixture have a crucial impact on the overall performance and appearance of the lighting fixture. In order to beautify the appearance of the lighting fixture, improve the anti-corrosion and anti-oxidation capabilities, and enhance the light reflection effect, spraying the outer wall of the lighting fixture has become a common processing method.
[0003] Spraying technology can effectively resist the damage caused by these harsh environments to the lighting fixture by forming a protective coating on the surface of the fixture. However, in the actual spraying process, since the outer wall of the lighting fixture is provided with a fixed-structure positioning base, when the paint is atomized into tiny particles by a spray gun and sprayed onto the surface of the object to be coated, if the distance between the spray gun and the object is too close, it may cause the paint to accumulate, forming a coating with uneven thickness and even causing sagging; if the distance between the spray gun and the object is too far, it may cause excessive atomization of the paint, resulting in a thin coating and affecting the protection effect. Therefore, a spraying device for the outer wall of a lighting fixture can be designed. Summary of the Invention
[0004] In order to overcome the problem that when the paint is atomized into tiny particles by a spray gun and sprayed onto the surface of the object to be coated, if the distance between the spray gun and the object is too close, it may cause the paint to accumulate, forming a coating with uneven thickness and even causing sagging; if the distance between the spray gun and the object is too far, it may cause excessive atomization of the paint, resulting in a thin coating.

[0014] Advantages of the present invention: 1. By setting the lifting rod to drive the curved backboard to rise and fall, the nozzle can spray the outer wall of the lamp. With the occurrence of the spraying air flow, since the curved backboard is arranged in a streamline shape, the linear concentration of the nozzle is effectively avoided. The first angle pipe, the second angle pipe and the third angle pipe are used for steering angles, increasing the steering flexibility. For large-area flat surfaces or details such as corners and grooves on the outer wall of the lamp, it is ensured that the paint evenly covers the outer wall of the lamp. With each up and down movement of the lifting rod, the piston rod inside the air flow guiding tank is driven to be squeezed up and down. The air bag is filled and ejected through the air holes on the connecting plate, dispersing the atomization degree of the concentrated paint. The design of the air flow guiding tank and the diversion arc plate effectively guides the influence of the sprayed paint atomized liquid on the outer wall of the lamp and reduces the interference of the external air flow on the spraying process. The air holes and the filtering cavity opened on the inner side of the diversion arc plate further purify the spraying environment and ensure the purity and adhesion of the coating. In addition, the use of the filtering column and the one-way filtering membrane effectively avoids the influence of dust and impurities on the coating, improving the overall quality and aesthetics of the coating.
[0015] 2. With each rotation of the rotating disk, the second connecting gear meshes with the connecting tooth blocks, causing the hanging column to turn, avoiding a single side corresponding to the nozzle. And with multiple groups of hanging hooks, the lamp can be installed in an inclined or straight insertion manner, increasing the diversification effect of placement.
[0016] 3. Through the diversion arc plate, a single-layer spraying treatment of the outer wall of the lamp is formed to avoid the influence of the interactive flow of external gases and carry out barrier protection. According to the size of the outer wall of the lamp, it can be adjusted sequentially along the cross groove to increase the spraying air flow space, avoid concentration, and enhance the use protection effect.

The second driving motor 418 drives the rotating rod 417 to drive the first connecting gear 419 in turn, so that the first connecting gear 419 and the rotating gear ring 413 are meshed, thereby turning the first angle tube 409, the second angle tube 410 and the third angle tube 411 in turn, so as to achieve multi-angle injection. The hydraulic cylinder 422 drives the push rod 423 to drive the lifting rod 401 to rise and fall, and drives the nozzle 408 to correspond to the lighting fixture, covering the upper and lower parts with spraying. With each up and down movement of the lifting rod 401, the piston rod inside the air flow guide tank 3 is driven to squeeze up and down, and the gas enters the air bag 301 through the air inlet hole 305 and the one-way air inlet valve, thereby filling the air bag 301. The piston rod moves upward, squeezing the internal gas, and the gas passes through the air pipe 309 and the air hole 305 on the connecting plate 304 to be sprayed out by the one-way exhaust valve, dispersing the atomization degree of the concentrated paint, and the gas entrains the atomized paint liquid along the first air flow hole 207 and the second air flow hole 208. It is purified by the filter cavity and the filter column 210, and is filtered and discharged from the other side outlet hole 209, which quickly disperses and purifies the internal impurity gas, avoids the blockage of the air inlet hole 305, and accelerates the internal flow rate.
[0029] Through the above steps, as the spraying airflow occurs, the curved support plate 406 is streamlined, which effectively avoids the linear concentration of the nozzle 408. The first angle tube 409, the second angle tube 410 and the third angle tube 411 are used to make the steering angle, thereby increasing the steering flexibility. For large-area flat surfaces of the outer wall of the lamp or details such as corners and grooves, the paint is ensured to be evenly covered on the outer wall of the lamp. With each up and down movement of the lifting rod 401, the piston rod inside the air flow guide tank 3 is driven to be squeezed up and down, and the filled airbag 301 is sprayed out through the air hole 305 on the connecting plate 304, thereby dispersing the atomization degree of the concentrated paint and increasing the overall processing effect.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
