[0002] When applying paints such as stone paint in decoration and renovation projects, it is common to encounter the edges and corners of the sprayed surface. It is easy to go over the boundary and cause the color to overflow the sprayed area. Usually, the construction workers need to cover up the overflow beforehand or deal with it afterward, which is a relatively cumbersome process and requires extra care during the spraying process. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary tool for spraying paint on the inner corner of a boundary, comprising two sets of vertically fixed adjustment plates, with one side of the two sets of adjustment plates perpendicularly connected to each other. At least one set of adjusters is spaced apart on the upper surface of each adjustment plate. A support is rotatably connected to each adjustment plate via a rotating connecting seat. A nozzle retainer is provided at the end of the support facing away from the rotating connecting seat. A fan is mounted on each adjustment plate. An air groove and an equalization groove are formed inside each adjustment plate. An equalization plate is fixedly connected to the bottom of the equalization groove.

[0005] As a further preferred embodiment, the rotating connecting seat has three sets, two sets of rotating connecting seats are fixedly connected to the adjacent sides of the two sets of adjusting plates, and the other set of rotating connecting seats is set on the included angle line of the two sets of adjusting plates. The two sets of adjusting plates are provided with nozzle retainers through the rotating connecting seats and the support. The nozzle retainers limit the position of the support, so that the positions of the support and the nozzle retainers are fixed at the same time.

[0006] As a further preferred embodiment, the air trough is connected to the equalization trough, the output end of the fan is located on the inner wall of the equalization trough, the gas blown out by the fan will enter the interior of at least one set of air troughs through the equalization trough, and the equalization trough ensures that each airflow entering the air trough has the same size through the equalization plate.

[0007] As a further preferred embodiment, the regulator includes at least one set of air output balls, and the at least one set of air output balls are sequentially fixedly connected by connecting rods. Each air output ball is fixedly connected to an adjusting rod by the connecting rods, and the adjusting rod is disposed on the side end face of the adjusting plate. By rotating the adjusting rod, the air output ball rotates on the upper end face of the adjusting plate. The side end face of the air output ball is provided with a spray groove and a spray support groove, and the spray groove and the spray support groove are connected inside the air output ball.

[0008] As a further preferred embodiment, there is at least one set of injection support slots, and the openings of the injection slots and injection support slots on the surface of the air output ball are opposite to each other, so that the injection slots or injection support slots on the air output ball are exposed outside the adjustment plate when the adjustment rod is rotated.

[0009] As a further preferred embodiment, the air output ball portion of the at least one set of regulators is located inside the air slot, and the airflow entering the air slot will be ejected from the outside of the regulating plate through the injection slot and the injection support slot.

[0010] As a further preferred embodiment, the support includes a telescopic rod, one end of which is fixedly connected to a fixing ring, and the nozzle retainer is sleeved inside the fixing ring. The fixing rings on the three sets of supports will completely cover the nozzle retainer.

[0011] As a further preferred embodiment, the telescopic rod has three sets of mutually sliding connections, and the three sets of telescopic rods are fixed by fixing bolts and fixing nuts. The cross-sectional size of the three sets of telescopic rods decreases sequentially. The three sets of telescopic rods are mutually sliding connections and can be stored inside the set of telescopic rods with the largest cross-section. Fixing grooves are opened on the front end faces of the two sets of stored telescopic rods, and the fixing bolts pass through the fixing grooves.

[0012] As a further preferred embodiment, the fixing bolt and the fixing nut are fixedly connected by threads, and when the fixing bolt fixes the telescopic rod, a washer is provided on the side of the fixing nut adjacent to the telescopic rod.

[0013] As a further preferred embodiment, the nozzle holder includes a nozzle fixing tube, the nozzle fixing tube having an installation groove inside, an airbag fixedly connected to the middle of the inner wall of the installation groove, and a set of limiting rings on each side of the airbag. By placing the nozzle of the spray gun into the installation groove, the nozzle squeezes the airbag to deform it, and the limiting rings on both sides of the airbag move towards both ends of the installation groove.

[0014] As a further preferred embodiment, the inner cavity of the mounting groove is spindle-shaped. When the limiting rings on both sides of the airbag move to both sides of the mounting groove through the spindle-shaped mounting groove, they will contract, thereby limiting the spray gun inside the mounting groove. The limiting rings are fixedly connected to the side end face of the airbag, and the limiting rings are not fixed to the inner wall of the mounting groove.

[0030] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0031] This invention provides a spray gun auxiliary tool for spraying paint on the inner corner of the boundary, including two sets of vertically fixed adjustment plates 1, one side of the two sets of adjustment plates 1 is perpendicularly connected to each other, at least one set of adjusters 2 are arranged at intervals on the upper surface of the adjustment plate 1, the adjustment plate 1 is rotatably connected to the support 4 through the rotating connecting seat 3, the support 4 is provided with a nozzle retainer 5 at the end opposite to the rotating connecting seat 3, a fan 6 is installed on the adjustment plate 1, and an air groove 7 and an equalization groove 9 are opened inside the adjustment plate 1, and an equalization plate 8 is fixedly connected to the bottom of the equalization groove 9.

[0032] In this embodiment, there are three sets of rotating connecting seats 3. Two sets of rotating connecting seats 3 are fixedly connected to the adjacent side of the two sets of adjusting plates 1, and the other set of rotating connecting seats 3 is set on the included angle line of the two sets of adjusting plates 1. The two sets of adjusting plates 1 are provided with nozzle retainers 5 through rotating connecting seats 3 and support 4. The nozzle retainer 5 limits the support 4, so that the positions of the support 4 and the nozzle retainer 5 are fixed at the same time.

[0033] Specifically, the air trough 7 is connected to the equalization trough 9, and the output end of the fan 6 is set on the inner wall of the equalization trough 9. The gas blown out by the fan 6 will enter the interior of at least one set of air troughs 7 through the equalization trough 9, and the equalization trough 9 makes each airflow entering the air trough 7 the same size through the equalization plate 8.

[0034] Furthermore, such as Figure 3 As shown, the regulator 2 includes at least one set of air output balls 10, and the at least one set of air output balls 10 are sequentially fixedly connected by connecting rods 11. An adjusting rod 12 is fixedly connected to the air output balls 10 by the connecting rods 11. Specifically, the air output balls 10 connected to the adjusting rod 12 by the connecting rods 11 are any one of the outermost sets of the at least one set of air output balls 10 connected in sequence. The adjusting rod 12 is located on the side end face of the adjusting plate 1. By rotating the adjusting rod 12, the air output balls 10 rotate on the upper end face of the adjusting plate 1. The side end face of the air output balls 10 is provided with a spray groove 13 and a spray support groove 14, which are connected inside the air output balls 10.

[0035] Furthermore, there is at least one set of jet support grooves 14, and the openings of jet grooves 13 and jet support grooves 14 on the surface of air output ball 10 are opposite to each other. When the adjusting rod 12 is rotated, the jet grooves 13 or jet support grooves 14 on air output ball 10 are exposed outside the adjusting plate 1. The airflow ejected through the jet grooves 13 will concentrate the airflow bundle, while the airflow ejected by at least one set of jet support grooves 14 is more dispersed.

[0036] In this embodiment, at least one set of air output balls 10 on the same straight line are partially disposed inside the air groove 7. The airflow entering the air groove 7 will be ejected from the outside of the regulating plate 1 through the injection groove 13 and the injection support groove 14.

[0037] Among them, such as Figures 1-5 As shown, by rotating the adjusting rod 12, the spray groove 13 or spray support groove 14 can be adjusted to be exposed on the upper surface of the adjusting plate 1, and the jet direction of the spray groove 13 or spray support groove 14 on the upper surface of the adjusting plate 1 can be adjusted, so that the airflow ejected through the spray groove 13 or spray support groove 14 changes the direction of the paint sprayed by the spray gun, and the dispersion surface of the paint liquid sprayed by the spray gun will form two straight lines on the side adjacent to the two sets of adjusting plates 1, thereby achieving the purpose of controlling the paint spray boundary.

[0038] In this embodiment, as Figure 1 , Figure 6 and Figure 7 As shown, the support 4 includes a telescopic rod 16, one end of which is fixedly connected to a fixing ring 15. The nozzle retainer 5 is sleeved inside the fixing ring 15. The fixing rings 15 on the three sets of support 4 will completely cover the nozzle retainer 5. The fixing rings 15 are made of elastic material, and the inner diameter of the fixing rings 15 is slightly smaller than the outer diameter of the nozzle retainer 5, so that when the nozzle retainer 5 is covered by the three sets of fixing rings 15, it is in a fixed state.

[0039] When the three sets of supports 4 move to the same horizontal line, they are in a spaced-out state.

[0040] Specifically, the telescopic rod 16 has three sets of sliding connections, and the three sets of telescopic rods 16 are fixed by fixing bolts 17 and fixing nuts 18. The cross-sectional size of the three sets of telescopic rods 16 decreases sequentially. The three sets of telescopic rods 16 are slidingly connected to each other and can be stored inside the set of telescopic rods 16 with the largest cross-section. Fixing grooves are opened on the front end faces of the two sets of stored telescopic rods 16, and fixing bolts 17 pass through the fixing grooves.

[0041] Before attaching the nozzle holder 5, the length and rotation angle of the telescopic rod 16 can be adjusted to adjust the position of the three sets of fixing rings 15 between the two sets of adjusting plates 1, so that the spray gun can be adjusted between the two sets of adjusting plates 1. In turn, by adjusting the position of the spray gun, the position of the high concentration point of the paint sprayed from the spray gun can be adjusted.

[0042] In this embodiment, as Figure 6 As shown, the fixing bolt 17 and the fixing nut 18 are fixedly connected by threads. When the fixing bolt 17 fixes the telescopic rod 16, a washer is provided on the side of the fixing nut 18 adjacent to the telescopic rod 16, so that after the fixing bolt 17 passes through the telescopic rod 16 and the fixing groove, the telescopic rod 16 after telescopic adjustment can be fixed through the fixing nut 18 and the washer.

[0043] In this embodiment, the nozzle holder 5 includes a nozzle fixing tube 19, and an installation groove 21 is provided inside the nozzle fixing tube 19. An airbag 20 is fixedly connected to the middle of the inner wall of the installation groove 21. A set of limiting rings 22 is provided on each side of the airbag 20. When the nozzle of the spray gun is placed into the installation groove 21, the nozzle squeezes the airbag 20 to deform it, and the limiting rings 22 on both sides of the airbag 20 will move to both ends of the installation groove 21.

[0044] Specifically, the inner cavity of the mounting groove 21 is spindle-shaped. When the limiting rings 22 on both sides of the airbag 20 move to both sides of the mounting groove 21 through the spindle-shaped mounting groove 21, they will contract, thereby limiting the spray gun inside the mounting groove 21. The limiting rings 22 are fixedly connected to the side end face of the airbag 20, and the limiting rings 22 are not fixed to the inner wall of the mounting groove 21.

[0045] When the nozzle of the spray gun is placed inside the mounting groove 21, the nozzle will squeeze the airbag 20 to make one end of the limiting ring 22 on both sides. For nozzles with different outer diameters, the movement distance of the limiting ring 22 will be different. In addition, the spindle-shaped structure inside the mounting groove 21 makes the final position of the limiting ring 22 move so that it just limits the nozzle through the inner wall of the mounting groove 21.

[0046] Furthermore, the limiting ring 22 fixes the nozzle so that it is not easy to shake, but the nozzle can rotate inside the mounting groove 21. By rotating the adjusting plate 1, the paint at the four corners of the nozzle's air-permeable and diffused surface can be limited, thus making the device more versatile.

[0047] In other embodiments, a handle is provided on the side of each of the two sets of adjustment plates 1 away from the adjuster 2. The handle can be made of scrap steel bars or wooden boards.

[0048] Working principle: When performing paint spraying, first adjust the extension length of the three sets of telescopic rods 16 so that the three sets of fixing rings 15 are on the same horizontal line. Then, put the nozzle holder 5 into the three sets of fixing rings 15, and then put the nozzle into the nozzle holder 5. Start the spray gun, and then blow air into the equalization tank 9 through the fan 6. The equalization tank 9 sprays air out from the air output ball 10 through the air groove 7. By rotating the adjusting rod 12, the spray groove 13 or spray support groove 14 on the air output ball 10 is exposed from the surface of the adjusting plate 1. The airflow sprayed by at least one set of air output balls 10 on the adjusting plate 1 adjusts the dispersion surface of the paint sprayed by the nozzle. The two sides of the dispersion surface sprayed by the nozzle are bound, completing the spraying operation of the corners where the wall and column are connected, the inside corners of the wall, the eaves and other corners that need to be sprayed.

[0049] In summary, the present invention provides a spray gun auxiliary tool for spraying paint on the inside corner of the boundary. It consists of two sets of adjusting plates 1 connected perpendicularly to each other, and at least one set of adjusters 2 is provided on the adjacent side of the two sets. The air output ball 10 protrudes from the adjacent side of the two sets of adjusting plates 1. The air output ball 10 is sprayed by the fan 6, so that the air output ball 10 sprays air to adjust the paint dispersion surface sprayed by the nozzle, control the shape of the paint dispersion surface, and facilitate its application to the inside corner of the wall and column connection, the inside corner of the wall, the eaves and other corners that need to be sprayed in a partial area. It effectively reduces the situation that the paint often goes beyond the boundary and the paint overflows the sprayed area during spraying. It effectively saves manpower and material resources for pre-masking or post-treatment. Moreover, the airflow control ensures that the device will not be contaminated with paint during use and does not require cleaning.
