Description

Technical Field

[0001] This utility model relates to the field of painting device technology, and in particular to a painting device for building walls. Background Technology

[0002] After a building is completed, paint or other coatings need to be sprayed onto the surface of the building walls to protect the walls and enhance their aesthetics. When it is necessary to spray paint or other coatings onto the wall surface, a spray gun is often used. A spray gun is a spraying tool consisting of a nozzle and a gun body. Its operating principle is to use compressed air as the power source, which is sprayed out from the air cap inside the air spray gun and generates a strong negative pressure at the front of the nozzle, drawing the paint out of the nozzle. Under the action of the high-speed jet force of the compressed air, the paint is atomized into fine droplets and evenly sprayed onto the surface of the workpiece.

[0003] Existing spray guns often suffer from misoperation due to the lack of a trigger-locking mechanism. This can lead to accidental spraying caused by collisions or operator errors. Since paint and other coatings are difficult to clean, accidental spraying can result in paint getting onto other parts of the wall or the operator, disrupting the painting process and hindering subsequent cleaning. Therefore, this application provides a building wall painting device to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a building wall painting device to solve the problem that the existing paint spray gun cannot fix the trigger and often causes accidental spraying.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A building wall painting device includes a main body, a trigger on the outer side of the main body, a first shaft fixedly connected inside the trigger, a first handle rotatably connected to the outer side of the first shaft, a first limiting hook fixedly connected to the outer side of the first handle, and a second limiting hook fixedly connected to the outer side of the first shaft; and a fixing assembly for fixing the trigger in multiple stages, the fixing assembly being connected to the main body.

[0007] Optionally, the fixing component includes a support frame fixedly connected to one side of the body, and a limit baffle is slidably connected to the top of the support frame.

[0008] Optionally, a spring sheet is fixedly connected to one side of the limiting baffle, and the spring sheet is fixedly connected to one side of the body.

[0009] Optionally, the limiting baffle is slidably connected to the outside of the main body, and a second handle is fixedly connected to both ends of the limiting baffle.

[0010] Optionally, the second handle is slidably connected to one side of the body.

[0011] Optionally, the support frame is internally rotatably connected to a second shaft.

[0012] Optionally, a first torsion spring is provided on one side of the support frame, and the first torsion spring is fixedly connected to one end of the second shaft.

[0013] Optionally, a fixing frame is fixedly connected to the outer side of the second shaft, and a transmission frame is fixedly connected to the outer side of the second shaft.

[0014] Optionally, a positioning bracket is fixedly connected to the outer side of the second shaft.

[0015] Optionally, a second torsion spring is provided on the outer side of the first shaft, and the second torsion spring is fixedly connected to one side of the first handle.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, a transmission frame is set up, which contacts the trigger. A limit baffle is set above the positioning frame. The limit baffle limits the positioning frame, so that the second shaft cannot rotate. When the trigger is squeezed, the trigger cannot be flipped inward due to the limit of the transmission frame, thus preventing the paint from being sprayed out. This prevents accidental spraying when the spray gun is not in use, thereby avoiding paint from getting on other parts of the wall and the operator's body due to accidental spraying.

[0018] By setting a first limiting hook and a fixing frame, when the trigger is squeezed to spray paint, the transmission frame will simultaneously flip to one side, causing the fixing frame to rotate in the direction of the trigger. At this time, by simultaneously squeezing the first handle to rotate it, after the trigger flips inward to a certain position, the first or second limiting hook is engaged with one side of the fixing frame, forming a locking engagement, thereby fixing the trigger in the corresponding position. When the first limiting hook is engaged with the fixing frame, the spray gun can spray paint without squeezing the trigger. Therefore, when spraying large areas of walls, it is not necessary to squeeze the trigger for a long time, reducing the labor intensity of the operator. At the same time, when the second limiting hook is engaged with the fixing frame, the spray gun can be in a state of spraying only gas, which is convenient for cleaning dust on the wall surface.

[0032] like Figures 1 to 4As shown, an embodiment of this utility model provides a building wall painting device, including a body 1. A trigger 2 is provided on the outer side of the body 1. A first shaft 3 is fixedly connected inside the trigger 2. A first handle 4 is rotatably connected to the outer side of the first shaft 3. The first handle 4 is positioned at the index finger, so that it can be easily pressed without affecting the operation of the trigger 2. A first limiting hook 5 is fixedly connected to the outer side of the first handle 4. A second limiting hook 6 is fixedly connected to the outer side of the first shaft 3. The length of the second limiting hook 6 is greater than that of the first limiting hook 5, so that when the trigger 2 is fixed, the rotation angle of the trigger 2 is much smaller than that when the trigger 2 is fixed by the first limiting hook 5. A fixing component is used to fix the trigger 2 in multiple stages. The fixing component is connected to the body 1 and includes a support frame 7 fixedly connected to one side of the body 1. A limiting baffle 8 is slidably connected to the top of the support frame 7. A spring piece 9 is fixedly connected to one side of the limiting baffle 8. The spring piece 9 can make The limiting baffle 8 is reset in time. The spring piece 9 is fixedly connected to one side of the main body 1. The limiting baffle 8 is slidably connected to the outside of the main body 1. The two ends of the limiting baffle 8 are fixedly connected to the second handle 10. The position of the second handle 10 is set at the thumb, and the outline of the second handle 10 is adapted to the thumb, thereby improving the convenience of operating the limiting baffle 8. The second handle 10 is slidably connected to one side of the main body 1. The support frame 7 is rotatably connected to the second shaft 11. The support frame 7 is provided with a first torsion spring 12 on one side. The first torsion spring 12 can make the second shaft 11 reset in time. The first torsion spring 12 is fixedly connected to one end of the second shaft 11. The outside of the second shaft 11 is fixedly connected to the fixing frame 13. The outside of the second shaft 11 is fixedly connected to the transmission frame 14. The outside of the second shaft 11 is fixedly connected to the positioning frame 15. The outside of the first shaft 3 is provided with a second torsion spring 16. The second torsion spring 16 can make the first handle 4 reset in time. The second torsion spring 16 is fixedly connected to one side of the first handle 4.

[0033] With the transmission frame 14 in place, when the spray gun is not in use, the trigger 2 is in a loose state. At this time, the second shaft 11 will be reset to its initial state under the action of the first torsion spring 12. The positioning frame 15 is limited by the limit baffle 8, so that the second shaft 11 cannot rotate counterclockwise, and thus the transmission frame 14 cannot be flipped downward. When the trigger 2 is squeezed, the trigger 2 cannot retract inward under the limit of the transmission frame 14, so the paint will not be sprayed out, thus preventing accidental spraying and avoiding paint from getting on other parts of the wall and the operator's body due to accidental spraying.

[0034] With the first limiting hook 5 and the fixing bracket 13 in place, when painting the wall, pulling the second handle 10 with the thumb causes the positioning bracket 15 to lose its limiting position. Squeezing the trigger 2 then sprays paint. Because the trigger 2 limits the transmission bracket 14, causing it to flip downwards, the fixing bracket 13 flips to one side, approaching the trigger 2. At this point, squeezing the first handle 4 with the index finger causes it to flip, resulting in the first limiting hook 5 flipping significantly inwards. Once the first limiting hook 5 has passed the fixing bracket 13, releasing the first handle 4... The first limiting hook 5 rests on the outside of the fixing frame 13, thereby engaging and limiting the trigger 2 in the current state. This eliminates the need to squeeze the trigger 2 for extended periods, reducing the operator's workload. Simultaneously, by squeezing the first handle 4 to slightly rotate it, the second limiting hook 6 engages with the fixing frame 13, fixing the trigger 2 in a position where only gas is ejected. This prevents excessive squeezing of the trigger 2 from causing paint to spray out as well, thus facilitating operator use and reducing operational intensity.

[0035] The working principle of the technical solution provided by this utility model is as follows:

[0036] When painting the wall, pulling the second handle 10 with your thumb disengages the positioning bracket 15 from the limiting baffle 8. Squeezing the trigger 2 then sprays out paint for painting. When painting a large area of ​​the wall requires prolonged squeezing of the trigger 2, the first limiting hook 5 engages with the fixing bracket 13. When the trigger 2 is squeezed inwards, it limits the transmission bracket 14, causing it to flip downwards. Simultaneously, the second shaft 11 rotates, stretching the first torsion spring 12 on one side, causing the fixing bracket 13 to flip to one side. Turn the trigger 2 closer and simultaneously pinch the first handle 4 with your index finger to flip it. The second torsion spring 16 on one side will stretch, causing the first limiting hook 5 to flip significantly inward. After the first limiting hook 5 passes the fixing frame 13, release the first handle 4. Under the contraction of the second torsion spring 16, the first handle 4 will reverse and return to its original position, and the first limiting hook 5 will engage with the outside of the fixing frame 13, thus locking the trigger 2 in its current state. This eliminates the need to pinch the trigger 2 for extended periods, reducing the operator's workload. Simultaneously, by squeezing the first handle 4 to slightly rotate it, the second limiting hook 6 can be engaged with the fixing frame 13, thus fixing the trigger 2 in a slightly inward-rotated state. Since the trigger 2 of the spray gun only sprays gas and not paint when slightly squeezed, it can be used to blow away dust on the wall, allowing the paint to adhere better to the wall surface. By engaging the second limiting hook 6 with the fixing frame 13, the trigger 2 can be fixed in the position where only gas is sprayed, thus avoiding the phenomenon of paint being sprayed out when the trigger 2 is squeezed excessively. When it is necessary to adjust the second shaft... When resetting, by squeezing the first handle 4 to the maximum angle, the first limiting hook 5 or the second limiting hook 6 is separated from the fixing frame 13, and the trigger 2 is released. At this time, the second shaft 11 is reset under the contraction of the first torsion spring 12. By pushing the second handle 10, the positioning frame 15 is released after passing the limiting baffle 8. At this time, the limiting baffle 8 is reset under the action of the spring 9 and slides to the top of the positioning frame 15 to limit the positioning frame 15. At this time, the transmission frame 14 abuts against the inside of the trigger 2, so that the trigger 2 cannot be flipped inward, thereby avoiding the phenomenon of accidental spraying of the spray gun.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.
