DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 - Figure 4 As shown, a spray gun for painting is mainly composed of the following parts: the gun body 1 is the main part of the spray gun, responsible for supporting and fixing other components; the nozzle 2 is located at the front end of the gun body 1, used to spray paint; the first interface 3 and the second interface 4 are respectively installed on the side walls of the gun body 1, used to connect paint and compressed air, etc.; the mounting block 5 is arranged on the side wall of the gun body 1, used to install the connecting block 6; the connecting block 6 is connected to the mounting block 5, and a connecting sleeve 8 is provided at the outer end; the connecting sleeve 8 and the hand-held sleeve 9 are integrally formed for convenient hand-held operation. The outer wall corners of the hand-held sleeve 9 are arc-shaped for easy holding; the flip bar 10 is arranged in the upper end groove 14 of the hand-held sleeve 9, which can be rotated and connected to the automatic painting mobile equipment through the first screw hole 13 and the second screw hole 15 with the groove 14. The inner wall of the flip bar 10 is attached with a rubber pad to increase friction;

[0028] Installation and fixation: Both the mounting block 5 and the connecting block 6 are provided with mounting holes 7, which are fixed by inserting bolts; Perforation and connection: The first perforation 11 and the second perforation 12 are located on the connecting block 6, and are used to allow the pipes of the first interface 3 and the second interface 4 to pass through and extend to the automatic painting mobile device for connection. Both perforations are waist holes, with rubber sleeves glued inside to ensure that the pipe connection is stable and sealed; the maximum flip angle of the flip bar 10 with flip function is ninety degrees, which is convenient for adjusting the angle of the spray gun. The flip bar 10 is connected to the handheld sleeve 9 through a rotating shaft and fixed by a buckle to ensure stability during use; screw hole design: The first screw hole 13 and the second screw hole 15 are blind holes with the same diameter, which is convenient for connection with the automatic painting mobile device;

[0029] This spray gun is specially designed for railway coach casings. It has a reasonable structure and is easy to operate. It can be used with automated painting mobile equipment to greatly improve painting efficiency and quality. The stability and durability of the spray gun are ensured through clever design and high-quality material selection.

[0030] The conversion process is as follows: when manual painting is required, the user can hold the hand-held sleeve 9, and the arc design at the corner of the outer wall of the sleeve makes it more comfortable to hold. The user can adjust the angle of the spray gun through the flip bar 10 to adapt to different painting needs. The rubber pad on the inner wall of the flip bar 10 increases the friction, making the adjustment more convenient and stable.

[0031] When it is necessary to use with the automatic painting mobile device, the user first rotates the flip bar 10 to a position perpendicular to the sink 14. Then, the automatic painting mobile device is connected through the first screw hole 13 and the second screw hole 15. The two screw holes are blind holes with the same diameter, ensuring a stable connection with the device; the mounting hole 7 on the mounting block 5 and the connecting block 6 is fixed by inserting bolts to ensure the stability of the spray gun on the mobile device. The first perforation 11 and the second perforation 12 on the connecting block 6 allow the pipes of the first interface 3 and the second interface 4 to pass through and extend to the automatic painting mobile device for connection. Both perforations are waist holes with rubber sleeves bonded inside, which ensures the stability of the pipe connection and the sealing; when the spray gun is firmly connected to the automatic painting mobile device, the user can start the device and start the automatic painting operation. This spray gun has a reasonable structure and simple operation, which can greatly improve the efficiency and quality of painting; the conversion process between handheld use and the mobile painting device is simple and efficient, meeting the needs of different painting scenes.
