[0023] The utility model provides a technical solution: Figure 1 - Figure 5As shown, in this embodiment, a paint splash prevention device for spraying automobile parts includes a spray box 1, one side of the inner wall of the spray box 1 is fixedly connected with a feed pipe 4, one end of the feed pipe 4 is fixedly connected with a spray hose 18, one end of the spray hose 18 is fixedly installed with a nozzle 20, and one side of the outer surface of the spray hose 18 is fixedly connected with a mounting cylinder 6, one side of the inner wall of the mounting cylinder 6 is provided with a threaded groove 10, the inner wall of the threaded groove 10 is threadedly connected with a threaded cylinder 7, one side of the inner wall of the threaded cylinder 7 is provided with an oblique groove 21, and the other side of the inner wall of the mounting cylinder 6 is fixedly connected with a mounting ring 8, one side of the mounting ring 8 is fixedly connected with a plurality of metal spring sheets 9, one side of the outer surface of the plurality of metal spring sheets 9 abuts against the inner wall of the oblique groove 21, a connecting pipe 22 is provided inside the mounting cylinder 6, one end of the connecting pipe 22 is fixedly connected with a splash prevention cover 5, and the outer surface of the connecting pipe 22 is connected to the plurality of metal spring sheets 9. One side of the spring piece 9 is engaged, and the threaded barrel 7 is rotated to move the threaded barrel 7 a distance in the mounting barrel 6, and one side of the metal spring piece 9 is moved out of the inclined groove 21. The elastic force of the metal spring pieces 9 themselves separates them from each other, releasing the restriction of the connecting pipe 22, and the connecting pipe 22 is pulled out from the mounting barrel 6, and then one end of the inclined groove 21 on the replacement splash guard 5 is passed through the threaded barrel 7 into the mounting barrel 6, and the threaded barrel 7 is rotated in the opposite direction. When the inner wall of the inclined groove 21 fits with one side of the metal spring piece 9, the threaded barrel 7 is rotated again to move the threaded barrel 7 a distance in the mounting barrel 6, so that the threaded barrel 7 squeezes multiple metal spring pieces 9, and the inner wall of the metal spring piece 9 fixes the connecting pipe 22 in the mounting barrel 6. With this structural design, the splash guard 5 can be quickly replaced by simply rotating the threaded barrel 7, avoiding long-term use of the splash guard 5 and affecting the quality of the spraying of automobile parts.

[0024] like Figure 5 As shown, a plurality of friction grooves 19 are provided on the outer surface of the threaded barrel 7 . The structural design of the friction grooves 19 increases the friction on the surface of the threaded barrel 7 , making it easier for workers to rotate the threaded barrel 7 .

[0025] like Figure 3 and Figure 4 As shown, a reciprocating device 17 is fixedly installed on one side of the inner wall of the spray box 1, and one side of the reciprocating platform of the reciprocating device 17 is fixedly connected to the outer surface of the spray hose 18. Through the structural design of the reciprocating device 17, the splash guard 5 can slide back and forth in the water pump 2 to improve the spraying effect.

[0026] like Figure 1 and Figure 2 As shown, a paint storage tank 3 is fixedly connected to one side of the spray box 1, and a water pump 2 is fixedly installed on the upper end of the paint storage tank 3. The output end of the water pump 2 is fixedly connected to the other end of the feed pipe 4, and the input end of the water pump 2 is located inside the paint storage tank 3.

The output end of the driving device 15 is transmission-connected to a placement rack 16. By turning on the driving device 15, the placement rack 16 is rotated in the spray box 1, and the automobile parts fixed in the placement rack 16 are rotated, so that the automobile parts can be sprayed without dead angles, thereby improving the spraying quality.

[0030] The utility model provides a paint splash prevention device for spraying automobile parts. The specific working principle is as follows:

[0031] When spraying automobile parts, first place the automobile parts on the placement rack 16 for fixing, close the spray box 1, start the water pump 2, and spray the automobile parts with the nozzle 20. At the same time, turn on the driving device 15 to rotate the automobile parts for spraying without dead angles. After spraying is completed, turn on the ultraviolet curing lamp 13 to cure the sprayed paint, thereby completing the spraying. When the anti-splash cover 5 is used for a long time and a lot of paint residue is adhered to the inner wall of the anti-splash cover 5, rotate the threaded barrel 7 and move the threaded barrel 7 a distance in the mounting barrel 6. One side of the metal spring sheet 9 is moved from the inclined groove 21. Remove, the elastic force of the metal spring pieces 9 separates them from each other, releasing the restriction of the connecting tube 22, and pulling the connecting tube 22 out of the mounting tube 6. Then, pass one end of the inclined groove 21 on the replacement splash guard 5 through the threaded tube 7 into the mounting tube 6, and rotate the threaded tube 7 in the opposite direction. When the inner wall of the inclined groove 21 fits with one side of the metal spring piece 9, rotate the threaded tube 7 again to move the threaded tube 7 in the mounting tube 6 for a distance, so that the threaded tube 7 squeezes multiple metal spring pieces 9. The inner wall of the metal spring piece 9 fixes the connecting tube 22 in the mounting tube 6. The replacement is completed, and the above operation is repeated to spray the automotive parts.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
