TECHNICAL FIELD
[0001] The present scheme relates to the technical field of protective paint spraying structure, and particularly relates to a protective paint spraying structure. BACKGROUND
[0002] After the automobile lampshade is manufactured, a process step of laser etching and paint spraying is needed. Before paint spraying, the area (lampshade inner cavity) of the automobile lampshade that does not need to be sprayed is covered to prevent paint from being sprayed to the area that does not need to be sprayed. Generally, film cloth or a cover plate is used for covering. Since the product that needs to be sprayed is an irregular curved surface, the opening is arranged up and down. The existing technology cannot be completely attached and is prone to the phenomenon of paint flying.
[0003] Therefore, a tool structure is needed to prevent the phenomenon of paint flying and avoid the non-paint spraying area from being contaminated by paint. SUMMARY

[0006] Further, the base is attached to the bottom of the lampshade, and the first concave part and the first convex part of the base are used for fixing the lampshade.
[0007] Further, the first concave part is provided with four parts corresponding to the convex part of the lampshade.
[0008] Further, the first convex part is provided with two parts aligned with the opening of the lampshade.
[0009] Further, the base is symmetrically provided with two inclined butt joints in the middle, the inclination angle is consistent with the lampshade, and the butt joint includes a second concave part and a second convex part limiting the top cover.
[0010] Further, the second concave part is arranged at the top center of the butt joint, and two frame bodies are arranged beside the second concave part, and the second convex part is included in the middle of the frame body.
[0011] Further, the second convex part is a wedge-shaped structure.
[0012] Further, the top cover is recessed at the bottom edge for fixing the gasket, and the third convex part corresponding to the second concave part is included on the protruding table in the middle of the bottom surface, and the third concave part corresponds to the second convex part.
[0013] Further, the inside of the third concave part is a wedge-shaped structure corresponding to the second convex part, and the outside of the third concave part includes a groove corresponding to the frame body.
[0014] Further, the gasket is a foam.
[0015] In summary, the present application has the following advantages:
[0016] The base provided by the present application fixes the top cover and the lampshade through the limiting structure, and shields the bottom of the lampshade to avoid paint entering the lampshade from the bottom.
[0017] The combination of the top cover and the gasket provided by the present application uses the compressible property of the foam to fill the gap between the top cover and the paint spraying part to increase the sealing property and avoid the paint flying phenomenon caused by incomplete fitting.

[0035] Two pairs of docking stations 13 are symmetrically arranged in the middle of the base 1, and the second recess 131 and the second protrusion 132 on the docking station 13 are used to limit the top cover 2. The docking station 13 is inclined to one side, and the inclination angle is consistent with the inclination angle of the lampshade. The second recess 131 is arranged at the top of the docking station 13, two frame bodies 133 are distributed beside the second recess 131, the second protrusion 132 is arranged in the middle of the frame body 133, and the second protrusion 132 is a wedge-shaped structure.
