[0023] 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.

[0024] This utility model provides, for example Figure 1-5A spraying device for decoration and fitment as shown, comprising a spray gun body 1. One end of the spray gun body 1 is fixedly provided with a nozzle 2. An annular mounting seat 3 is sleeved outside the nozzle 2. A spray head 4 is provided outside the mounting seat 3. A connecting seat 5 is fixedly provided on the side of the spray head 4 close to the mounting seat 3, and the connecting seat 5 is arranged outside the nozzle 2 by means of threads. Baffles 6 are provided on both sides of the spray head 4. The baffles 6 are of a fan-shaped structure. The fan-shaped baffles 6 are similar to the spraying trajectory of the paint, which can achieve the shielding of the paint. Moreover, the end size of the fan-shaped structure is small, which is convenient for the user to observe the painting situation;

[0025] One end of each of the two baffles 6 is fixedly provided with a fixing block 7. Slots 8 are opened at both ends of the fixing block 7. Connecting rods 9 are fixedly provided on both sides of the mounting seat 3. The two ends of the two connecting rods 9 are respectively clamped in the slots 8 at both ends of the two fixing blocks 7. The fixing block 7 can deform when pressed and be clamped outside the connecting rod 9 to achieve the disassembly of the baffle 6;

[0026] Two fixing frames 10 are fixedly provided in the middle of the outer side of each baffle 6. A support rod 11 is provided outside the baffle 6. One end of the support rod 11 is fixedly provided with a sliding rod 12, and the two ends of the sliding rod 12 are respectively slidably arranged inside the two fixing frames 10. A fixing seat 13 is jointly arranged at one end of the two fixing frames 10. A positioning rod 14 is arranged in the middle of the fixing seat 13 by means of threads. Connecting blocks 15 are fixedly provided on both sides of the mounting seat 3. One end of the support rod 11 is movably connected to the outside of the connecting block 15 by means of a pin shaft;

[0027] A top spring 16 is fixedly provided at one end of the inner side wall of the fixing frame 10 close to the fixing seat 13. One end of the top spring 16 is fixedly provided with a slider 17, and the slider 17 is slidably arranged inside the fixing frame 10. It should be noted that considering that the slider 17 may break away from the inside of the fixing frame 10, the slider 17 can be set as a "C"-shaped structure. The slider 17 and the top spring 16 are used to exert a thrust on the sliding rod 12 so that the two baffles 6 maintain an inwardly contracted state, thereby ensuring that the baffles 6 are in contact with the building surface;

[0028] Grooves 18 are opened at both ends of the side of the baffle 6 away from the fixing block 7. A support 19 is fixedly provided at the notch of the groove 18 close to the outer side of the baffle 6. A guide wheel 20 is rotatably arranged inside the support 19. The guide wheel 20 is perpendicular to the baffle 6, and a fillet is provided at one end of the guide wheel 20. The setting of the fillet ensures that the guide wheel 20 can still be in contact with the building surface in an inclined state;

[0029] A positioning block 21 is fixedly provided on one side of the connecting seat 5. A plurality of positioning grooves 22 are annularly opened outside the mounting seat 3, and the plurality of positioning grooves 22 are all adapted to the positioning block 21. The positioning block 21 and the positioning groove 22 are used to lock the position between the mounting seat 3 and the spray head 4 to achieve the effect of locking the angle of the baffle 6;

[0030] Two inclined guide blocks 23 are fixedly provided on the outer side of the nozzle 4. Symmetrically distributed secondary discharge ports 24 are provided through the middle of the two guide blocks 23. A main discharge port 25 is provided through the middle of the nozzle 4. A guide cover 26 is fixedly provided on the outer side of the nozzle 4. The guide cover 26 is designed as a fan-shaped structure. The secondary discharge ports 24 and the main discharge ports 25 are both located inside the guide cover 26. The secondary discharge ports 24 and the main discharge ports 25 are used to spray out the paint.

[0031] Working principle of this utility model:

[0032] In use, first, the mounting base 3 is fitted onto the outside of the nozzle 2. Then, the nozzle 4 is installed on the outside of the nozzle 2 via the connecting base 5 and threads, ensuring that the positioning block 21 on the inside of the connecting base 5 is inserted into the positioning groove 22 on the outside of the mounting base 3. This completes the assembly of the device. After assembly, the spray gun body 1 is connected to the paint spraying machine. The paint spraying machine pressurizes the paint and delivers it into the spray gun body 1. The paint enters the nozzle 4 through the nozzle 2 and is then sprayed out through the main outlet 25 and the secondary outlet 24. Because the secondary outlet 24 is designed with an inclined structure, the paint is inclined after passing through the secondary outlet 24. The paint is sprayed at an angle, and after being sprayed, it is guided by the guide cover 26. The guide cover 26 is designed with a fan-shaped structure, so the paint is sprayed out in a fan-shaped structure. During the spraying process, the two baffles 6 are respectively attached to the two sides of the spraying area. After the paint is sprayed, the paint at the edge position is blocked by the baffles 6, which can limit the paint to be sprayed only in the designated area. During the spraying process, the user can hold the spray gun body 1 and move it to achieve spraying of multiple areas. During this process, the spray gun body 1 drives the baffles 6 to move, and the baffles 6 always maintain the shielding and protection of the two sides of the spray gun body 1.

[0033] During use, when the user places the spray gun body 1 outside the building painting area, the baffle 6 rotates around the connecting rod 9 due to the reaction force from the building surface. During this process, the baffle 6 presses the sliding rod 12 through the fixed frame 10, causing the sliding rod 12 to drive the support rod 11 to rotate. After sliding a certain distance, the sliding rod 12 is in contact with one end of the positioning rod 14. At this time, the sliding rod 12 can no longer slide, and the support rod 11 can no longer rotate, thus pressing the baffle 6 to limit the maximum opening and closing degree of the baffle 6. This allows control over the spray range of the spray gun body 1. By rotating the positioning rod 14 to make it slide horizontally, the maximum movement position of the sliding rod 12 can be adjusted, thereby adjusting the maximum opening and closing degree of the baffle 6 to change the maximum spray range of the spray gun body 1.

[0034] It should be noted that the spray gun body 1 in this embodiment adopts the corresponding structure in the prior art. It needs to be used with a paint spraying machine during application. This embodiment only provides the relevant technical solutions and structures after the paint is sprayed out, and does not limit the structure of the spray gun body 1 and the paint spraying machine.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
