Description

Technical Field

[0001] The utility model relates to a spray gun for coating spraying, belonging to the technical field of spray guns. Background Art

[0002] Paint spray guns are professional tools used for spraying paint, widely used in furniture, automobiles, construction, and other fields. Spray guns can be divided into various types based on their usage and operating principles. Spray guns can evenly and finely atomize paint into tiny particles, improving the uniformity and aesthetics of the coating. Adjustability: Parameters such as the spray volume, spray width, and spray pressure can be adjusted to meet different spraying needs. Durability: Spray guns are generally made of high-quality materials with good wear and corrosion resistance and a long service life. Wear protective equipment such as safety glasses, masks, and gloves during the spraying process to ensure safe operation. Clean and maintain the spray gun regularly to keep it in good working condition and spray results. Pay attention to the viscosity and dilution ratio of the paint to avoid paint clogging the spray gun nozzle. After spraying, clean the spray gun and store it properly to avoid moisture or damage.

[0003] A spray gun is a tool that uses the principle of air pressure difference to atomize paint and then spray it out. Most existing spray guns are handheld, and the nozzle is aimed at the target to release the paint. However, in actual spraying, the target area may not be a flat surface, especially the hidden corners of bent workpieces, such as U-shaped and Z-shaped steel workpieces. When using a spray gun for spraying, it is not easy to effectively deliver the nozzle to the target position. In addition, due to the limitations of the spray gun grip and the spraying site, it is difficult to effectively spray complex corners, which reduces the performance of the spray gun.

[0025] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0026] like Figure 1-3 As shown, the paint spraying spray gun includes:

[0027] The gun body consists of a handle 1 and a rod body 2. The top of the handle 1 is composed of the rod body 2. The ends of the rod body 2 are fixedly connected to the first fixing plate 9 and the second fixing plate 10 respectively by screws. The ends of the first fixing plate 9 and the second fixing plate 10 away from the rod body 2 are rotatably connected to the nozzle 8. The end of the rod body 2 is fixedly connected to the joint 6, and the joint 6 is connected to the nozzle 8 through a hose 7. An adjustment mechanism is provided at the top of the rod body 2, and the adjustment mechanism is transmission-connected to the nozzle 8.

[0028] The top of the rod body 2 is rotatably connected to a U-shaped handle 4, and the handle 4 is correspondingly arranged on one side of the handle 1. A piston rod 3 is sealed and inserted into the bottom end of the rod body 2, and the piston rod 3 is correspondingly arranged on one side of the joint 6. The end of the piston rod 3 located outside the rod body 2 is connected to the handle 4 through a connecting rod 5.

[0029] In this technical solution, when the handle 1 and the handle 4 are gripped, the handle 4 rotates around the top of the rod body 2 and pulls the connecting rod 5 and the piston rod 3 to move. When the piston rod 3 translates stably inside the rod body 2, the distance between the piston rod 3 and the joint 6 can be increased, thereby adjusting the efficiency of the paint delivery from the joint 6, which is used to adjust the paint spraying speed during spraying.

[0030] The cross-section of the nozzle 8 is a U-shaped structure. The nozzle 8 is connected to the inside of the rod body 2 through a hose 7. The hose 7 is located inside the nozzle 8. The top of the nozzle 8 is fixedly connected to a gear 12 located above the second fixed plate 10, and the top of the nozzle 8 is connected to the bottom of the second fixed plate 10 through a torsion spring 11. The first fixed plate 9 and the second fixed plate 10 are respectively located on the upper and lower sides of the nozzle 8.

[0031] In this technical solution, the first fixing plate 9 and the second fixing plate 10 are used to install the nozzle 8, so that the nozzle 8 can rotate between the first fixing plate 9 and the second fixing plate 10 to adjust the angle of the nozzle 8. When the nozzle 8 rotates, the hose 7 can be located inside the nozzle 8 of the U-shaped structure to avoid squeezing the hose 7, and after rotation, it can be reset by the torsion spring 11.

[0032] The adjusting mechanism includes a fixing seat 13, which is fixedly connected to the top of the rod body 2. A gear rod 15 is movably sleeved inside the fixing seat 13, and the gear rod 15 is meshed with the gear 12. A limit block 18 is fixedly connected to the top of the rod body 2, and the limit block 18 is correspondingly arranged on one side of the gear rod 15, and the gear rod 15 is fitly connected to the side wall of the limit block 18. The fixing seat 13 is a square hollow structure, and a long hole 14 is opened on one side of the fixing seat 13. The side wall of the gear rod 15 is fixedly connected to the stud 16, and the stud 16 is slidably connected to the inside of the long hole 14. The end of the stud 16 is threadedly connected to the knob 17, and the knob 17 is fitly connected to the side wall of the fixing seat 13.

[0033] In this technical solution, when adjusting, the gear rod 15 is moved, so that the gear rod 15 drives the gear 12 to rotate when it moves, and the gear 12 drives the nozzle 8 to rotate to adjust the angle. At this time, the torsion spring 11 is in a twisted state. When the gear rod 15 moves, it drives the stud 16 to move inside the long hole 14. When the adjustment is completed, tighten the knob 17 to make it rest against the side wall of the fixing seat 13, and then limit the gear rod 15 to achieve fixation after angle adjustment. The first fixing plate 9 and the second fixing plate 10 are extended into the object to be coated, and the nozzle 8 is rotated to achieve effective spraying of complex positions. When the operation is completed, unscrew the knob 17, use the torsion spring 11 to reset the nozzle 8, and tighten the knob 17 again to make the nozzle 8 face the spray gun directly, which is convenient for use.

[0034] The present invention is not limited to the above-described embodiments. Any changes in shape or structure fall within the scope of protection of the present invention. The scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications shall fall within the scope of protection of the present invention.
