[0025] 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. Example

[0026] Please see Figure 1-6 The present invention provides the following technical solution: a surface spraying device for metal workpieces, including a spray box 1, connecting blocks 2 are fixedly connected to the bottom of the spray box 1, support legs 3 are fixedly connected to the bottom of the connecting blocks 2, support feet 4 are fixedly connected to the bottom of the spray box 1, and support pads 5 are glued to the bottom of the support feet 4. The support pads 5 are rubber components, and a cross brace 6 is fixedly connected between the bottom ends of the front and rear support legs 3. The support legs 3 are used for raising and supporting the device. The support feet 4 can further increase the contact area between the bottom of the support legs 3 and the ground, making the support more stable. The support pads 5 can further improve the anti-slip effect between the support feet 4 and the ground, so as to ensure the stable support and use of the device.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, further, a screw hole 7 is provided at the middle of the bottom of the spray box 1. A screw rod 8 is screwed into the screw hole 7. A support plate 9 is fixedly connected to the upper end of the screw rod 8. A turntable 10 is fixedly connected to the bottom of the support plate 9. A handle 11 is fixedly connected to the bottom right side of the turntable 10. A handle sleeve 12 is fitted around the outside of the handle 11. The handle sleeve 12 is a rubber component. A support sleeve 13 is fixedly connected at the middle of the bottom of the spray box 1. A screw hole 14 is provided at the middle of the left side of the support sleeve 13. A locking bolt 15 is screwed into the screw hole 14. The support plate 9 is used to place metal workpieces in the spray box 1. The handle sleeve 12 is used to provide a non-slip grip for the handle 11. The height of the support plate 9 can be flexibly adjusted by rotating the handle 11, the turntable 10 and the support plate 9. It is simple and convenient.

[0028] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a feed pipe 17 is fixedly connected to the middle of the upper end of the spray box 1, and a nozzle 18 is screwed to the bottom end of the feed pipe 17. Transparent windows 16 are fixedly connected to both the front and rear sides of the upper interior of the spray box 1. The feed pipe 17 and the nozzle 18 are used to facilitate the spraying of metal workpieces inside the spray box 1. The paint is pumped in by an external liquid storage pump and sprayed out through the feed pipe 17 and the nozzle 18. The transparent window 16 allows for a direct and convenient view of the spraying of metal workpieces inside the spray box 1 from the outside.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the spray box 1 is further provided with a door 20 at the front end. The left side of the door 20 is rotatably connected to the spray box 1 through two pivots 19. A handle 21 is fixedly connected to the middle position of the front right side of the door 20. A slot 22 is opened at the front right side of the spray box 1. A magnetic strip 23 is fitted inside the slot 22, and the right side of the door 20 is magnetically connected to the magnetic strip 23. The handle 21 and the pivots 19 are used to push, pull, flip and open the door 20. The magnetic strip 23 is used to fix the closed door 20 to itself to prevent the closed door 20 from opening on its own. It is simple and convenient.

[0030] In this implementation scheme: The front magnetic door 20 of this utility model allows for convenient opening and closing of the spray box 1. By placing the metal workpiece on the support plate 9 inside the spray box 1, the surface coating is sprayed by the nozzle 18 on the spray box 1. This not only saves effort and is convenient, but also improves the coating efficiency. Furthermore, since the spraying is carried out inside the closed spray box 1, the coating is less likely to splash during the spraying process, which can greatly reduce the harm to the health of the workers. It is of superior quality. In addition, through the combination of screw hole 7, screw 8, support plate 9, turntable 10, and handle 11, the height of the support plate 9 can be further flexibly adjusted to accommodate metal workpieces of different heights for placement and spraying. The operation is simple and convenient, and the overall use is of superior quality.

[0031] The usage process and working principle of this utility model are as follows: Place the device in the designated location and connect the output hose of the external paint storage pump to the upper end of the feed pipe 17, and fix the connection. In use, pull the handle 21 outward to open the box door 20. The box door 20 can be rotated outward via the pivot 19. Then, place the metal workpiece to be sprayed in the center on the support plate 9, and then flip and close the box door 20. The box door 20 is magnetically connected to the magnetic strip 23, which can magnetically fix the closed box door 20. The handle 11 can drive the turntable 10 and the screw 8 to rotate, thereby driving the support plate 9 to rise and fall, thus adjusting the working height of the support plate 9. Then, tighten the locking bolt 15 on the support sleeve 13 to lock and fix the screw 8 after rotation and adjustment, so as to prevent the adjusted support plate from being locked. The support plate 9 can be rotated freely, and when placing metal workpieces of the same specifications in the subsequent workpieces, there is no need to repeatedly adjust the height of the support plate 9. Then, the external liquid pump is started, and the paint is input through the feed pipe 17 and sprayed out through the nozzle 18 to spray the surface of the metal workpieces on the support plate 9. After the spraying of this side is completed, the box door 20 can be opened to flip the metal workpieces over, and then the other side is sprayed in the same way. After the spraying is completed, the box door 20 can be opened to remove the metal workpieces. By placing the metal workpieces on the support plate 9 in the spray box 1 and spraying the surface paint through the nozzle 18 on the spray box 1, it is not only labor-saving and convenient, but also improves the paint spraying efficiency. Moreover, the spraying is carried out in the closed spray box 1, and the paint is not easy to splash during the spraying process, which can greatly reduce the harm to the health of the workers. It is better to use.
