[0023] See also Figure 1-5 The utility model provides a technical solution: a non-stop liquid insulated armor spray gun, comprising a spray gun body 1, a handle 2, a lithium battery pack 3, a connecting pipe 4, a spray pot 21, a nozzle 5 and a nozzle 6. The end faces of the nozzle 5 are located on both sides of the nozzle 6 and are connected with slide grooves 7. The slide grooves 7 are symmetrically provided with sealing plates 8 for adjusting the opening and closing size of the nozzle 6. A protruding rod 9 is fixed on the sealing plate 8. The end of the nozzle 5 is rotatably connected to a swivel 10. The swivel 10 is provided with a control groove 11 for the protruding rod 9 to pass through for controlling the movement of the sealing plate 8. The swivel 10 is provided with a discharge port 12 concentrically arranged with the nozzle 6.

[0024] Specifically, the width of the sealing plate 8 is greater than the diameter of the nozzle 6, ensuring that the two sealing plates 8 can completely cover the nozzle 6, thereby avoiding the sealing plate 8 failing to completely seal the nozzle 6 and causing multiple leakages. The sealing plate 8 is slidingly connected to the inner wall of the slide groove 7 to ensure the stability of the movement of the sealing plate 8, thereby ensuring the stability of the flow regulation of the nozzle 6.

[0025] Specifically, the two control grooves 11 are arc-shaped grooves and are symmetrically arranged along the center of the discharge port 12. The control grooves 11 are tilted toward the center of the discharge port 12. The rotating ring 10 is rotated so that the control grooves 11 apply force to the protruding rod 9, and the protruding rod 9 applies force to the sealing plate 8, so that the two sealing plates 8 move toward or away from each other in the slide groove 7 at the same time, thereby controlling the opening of the nozzle 6. The inner wall of the control groove 11 fits with the outer wall of the protruding rod 9, and the protruding rod 9 is a cylindrical rod, which improves the stability of the action between the control groove 11 and the protruding rod 9.

[0026] Specifically, an annular groove 13 is provided on the end face of the nozzle 5 outside the nozzle 6, and a convex ring 14 rotatably connected to the annular groove 13 is fixedly provided on the end face of the swivel 10. A limiting annular groove 15 is provided on the inner wall of the annular groove 13, and a limiting ring 16 is rotatably provided in the limiting annular groove 15. The limiting ring 16 is fixedly sleeved on the outer wall of the convex ring 14. The stability of the rotation of the swivel 10 is ensured by the limiting of the limiting ring 16 and the limiting annular groove 15.

[0027] Specifically, a card block groove 19 is provided on the end face of the convex ring 14, a card block spring 20 is fixedly provided in the card block groove 19, and the card block spring 20 is fixedly connected to the card block 18. A card groove 17 is provided on the inner wall of the bottom of the annular groove 13 for the card block 18 to be inserted into. There are multiple card grooves 17 evenly arranged along the bottom of the annular groove 13. The end of the card block 18 located outside the card block groove 19 is an arc surface and fits with the card groove 17. The limit of the card block 18 and the card groove 17 keeps the swivel 10 stable, thereby ensuring the stability of the sealing plate 8. To ensure the stability of the opening of the nozzle 6, when adjusting the opening of the nozzle 6, rotate the swivel 10, and the arc surface of the block 18 is compressed by the force of the slot 17 to slide the block spring 20 out of the slot 17. After the swivel 10 rotates a certain angle, the block 18 is opposite to the next slot 17. Under the elastic force of the block spring 20, the block 18 is clamped into the slot 17 to limit the swivel 10 again, so that the swivel 10 can be fixed after rotation, thereby improving the stability of the nozzle 6 opening adjustment.

[0028] Specifically, convex strips are provided on the outer wall of the swivel 10 and are evenly arranged along the outer wall of the swivel 10 , so as to increase the friction of the swivel 10 and facilitate the rotation of the swivel 10 .

[0029] Specifically, the spray gun body 1 is provided with a blocking and cleaning assembly 22 at the discharge port 12, and the blocking and cleaning assembly 22 includes a blocking disk 221 and a blocking rod 222, wherein the outer wall of the blocking rod 222 is fitted to the inner wall of the discharge port 12, and after the blocking rod 222 is fully inserted into the discharge port 12, the blocking disk 221 is fitted to the spray gun body 1, and an annular groove 223 is provided on the blocking rod 222, and a scraper rod 225 is axially provided on the inner wall of the annular groove 223, and the inside of the blocking rod 222 is hollow to form a collecting chamber, and a glue inlet 224 connected to the collecting chamber is provided at the connection between the annular groove 223 and the scraper rod 225 By setting up a blocking and cleaning component 22, after the spray gun main body 1 has finished spraying the insulating liquid, the blocking rod 222 of the blocking and cleaning component 22 is inserted into the discharge port 12. The marking groove 226 can be stopped at the top by rotating the blocking disk 221. During the rotation of the blocking rod 222, the insulator will enter the collecting chamber along the glue inlet 224, and then the blocking and cleaning component 22 is taken out for cleaning, which is convenient for cleaning the insulator in the discharge port 12. When the spray gun main body 1 is not in use, the blocking rod 222 can also be inserted into the discharge port 12 to effectively prevent pollutants from contaminating the spray gun main body 1.

[0030] A specific application example of this embodiment is:

[0031] When the device is in use, insulating liquid is put into the spray pot 21 and sprayed on the required armored area. When the flow rate needs to be adjusted, the rotating ring 10 is rotated so that the control groove 11 applies force to the protruding rod 9, and the protruding rod 9 applies force to the sealing plate 8, so that the two sealing plates 8 move toward or away from each other in the slide groove 7 at the same time, thereby controlling the opening of the nozzle 6. When the opening of the nozzle is small, the spray range is small but the spray distance is long. When the opening of the nozzle is large, the spray range is large but the spray distance is short. It can be adjusted according to needs, is easy to operate, and there is no need to replace the nozzle.

[0032] After the spray gun body 1 has finished spraying the insulating liquid, the sealing rod 222 of the sealing cleaning assembly 22 is inserted into the discharge port 12. The marking groove 226 can be stopped at the top by rotating the sealing disk 221, and then the sealing cleaning assembly 22 is taken out to facilitate the cleaning of the insulator in the discharge port 12. When the spray gun body 1 is not in use, the sealing rod 222 can also be inserted into the discharge port 12 to effectively prevent pollutants from contaminating the spray gun body 1.
