Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please see attached Figure 1-5 , this application provides the following three preferred embodiments.

[0027] Embodiment 1

[0028] A simple manual air pressure paint spraying device comprises:

[0029] A plug-in connection groove 2 is provided on the spray paint bucket 1, a reset unlocking groove 3 is provided on the inner side of the spray paint bucket 1, the plug-in connection groove 2 is communicated with the reset unlocking groove 3, the plug-in assembly is arranged on the inner side of the reset unlocking groove 3, the plug-in assembly includes a spray connector 4, a limit connecting plate 5, a plug-in fixing block 6, and a paint nozzle 13. A limit connecting plate 5 is provided on the inner side of the reset unlocking groove 3, and a plug-in fixing block 6 is provided on one side of the limit connecting plate 5. A spray connector 4 is provided on the inner side of the plug-in connection groove 2, and a paint nozzle 13 is provided on the inner side of the plug-in connection groove 2. The inner side of the paint nozzle 13 is engaged with the outer side of the spray connector 4. A connection fixing groove 14 is provided on the paint nozzle 13, and the plug-in fixing block 6 is provided on the inner side of the reset unlocking groove 3. One end of the fixed block 6 is inserted into the inner side of the connecting and fixing groove 14. When in use, select a suitable paint nozzle 13 according to the type of paint inside the spray paint bucket 1 and the required spraying method, align the paint nozzle 13 and the spray connection piece 4, rotate the paint nozzle 13 so that it is sleeved on the spray connection piece 4, and fix it by threaded connection. When the plug-in fixing block 6 is inserted into the inner side of the connecting and fixing groove 14 during rotation, continue to rotate to squeeze and shrink the plug-in fixing block 6 into the inner side of the reset unlocking groove 3 until the paint nozzle 13 is completely connected to the spray connection piece 4. At the same time, the plug-in fixing block 6 is inserted into the inner side of the connecting and fixing groove 14, so that the paint nozzle 13 cannot rotate in the opposite direction and fall off.

[0030] A simple manual pneumatic paint spraying device disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that a reset component is arranged on one side of the limiting connecting plate 5, and the reset component includes a guide sleeve 7, a guide constraint rod 8, and a reset spring 9. Two guide sleeves 7 are arranged on one side of the limiting connecting plate 5, and two guide constraint rods 8 are arranged on one side of the reset unlocking groove 3. Each guide sleeve 7 is sleeved on the corresponding guide constraint rod 8. Two reset springs 9 are arranged between the reset unlocking groove 3 and the limiting connecting plate 5. Each reset spring 9 is sleeved on the corresponding guide sleeve 7. When the plug-in fixing block 6 is retracted to the inner side of the reset unlocking groove 3, the limiting connecting plate 5 drives the plug-in fixing block 6 to reset through the reset spring 9.

[0031] A simple manual pneumatic paint spraying device disclosed in the third embodiment of the utility model has a structure that is basically the same as that in the second embodiment, and the difference lies in that: the unlocking component is connected to the limiting connecting plate 5, and the unlocking component includes a movable connecting block 10, an unlocking constraint block 11, and a sealing connecting block 12. A movable connecting block 10 is provided on one side of the limiting connecting plate 5, and an unlocking constraint block 11 is provided on one side of the movable connecting block 10. The unlocking constraint block 11 penetrates the spray paint bucket 1 and is suspended in the air. An unlocking sealing groove is provided on the inner side of the spray paint bucket 1, and a sealing connecting block 12 is provided on one side of the unlocking constraint block 11. The sealing connecting block 12 is arranged on the inner side of the unlocking sealing groove. When in use, the device is fixed by the plug-in component and the reset component. When the paint nozzle 13 needs to be replaced, the unlocking constraint block 11 is pulled upward, so that the movable connecting block 10 drives the limiting connecting plate 5 to move upward, thereby disengaging the plug-in fixing block 6 from the connecting fixing groove 14, and then the paint nozzle 13 is rotated outward until it is completely disengaged, wherein the sealing connecting block 12 isolates air from entering the inner side of the reset unlocking groove 3, thereby improving the service life of the device.
