Description

Technical Field

[0001] This utility model relates to the field of wall decoration technology, and in particular to a spraying device for interior wall decoration. Background Technology

[0002] As people's living standards gradually improve, their requirements for indoor living environments are also increasing. In the process of interior decoration, wall painting is a crucial step. In modern decoration, wall painting is no longer limited to using a single color and material; instead, it emphasizes artistry and human experience. Therefore, different walls are often painted with different materials and colors, or different areas of the same wall are painted with different materials and colors.

[0003] In existing technology, paintbrushes are a commonly used tool for painting walls. A typical paintbrush consists of a brush head and a brush handle. When using a paintbrush to paint a wall, the brush head is dipped in paint, and the brush handle is held to paint the wall.

[0004] However, when using traditional paint brushes for painting, the walls usually require a lot of paint. Therefore, the brush roller needs to pick up a large amount of paint during the painting process, and the paint will flow down the wall, forming paint drips. As a result, the wall needs to be painted repeatedly, resulting in low painting efficiency. To address these issues, a spraying device for interior wall decoration is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a spraying device for interior wall decoration, which aims to improve the problem in the prior art that the brush roller needs to pick up a large amount of paint during the wall painting process, and the paint will flow down the wall, requiring repeated painting of the wall surface, resulting in low painting efficiency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a spraying device for interior wall decoration, comprising a support rod, a connecting rod fixedly connected inside the support rod, a sealing plug rotatably connected to the outer wall of one end of the connecting rod, a spraying pipe fixedly connected to the outer wall of the sealing plug, a first painting roller fixedly connected to the outer wall of the spraying pipe, a second painting roller slidably connected to the outer wall of the spraying pipe, a nozzle disposed inside the spraying pipe, a regulating valve fixedly connected to one end of the spraying pipe, a material extraction pipe fixedly connected to the input end of the regulating valve, a connecting assembly disposed inside the first painting roller for connecting the first painting roller and the second painting roller, and a telescopic assembly disposed on the outer wall of the support rod for adjusting the painting height of the second painting roller;

[0007] The connecting assembly includes a support column and a retaining bead. The support column is slidably connected inside the first painting roller, and the retaining bead is fixedly connected to one end of the support column. A spring is sleeved on the outer wall of the support column. One end of the spring is fixedly connected to the outer wall of the retaining bead, and the other end of the spring is fixedly connected to the inside of the first painting roller. A retaining block is fixedly connected to one side of the second painting roller, and the retaining block engages with the retaining bead. A handle is fixedly connected to one end of the second painting roller.

[0008] As a further description of the above technical solution: the telescopic assembly includes a connecting column and a handle, the connecting column being slidably connected to the outer wall of the support rod, and the handle being slidably connected to the outer wall of the connecting column.

[0009] As a further description of the above technical solution: an internal rack is fixedly connected inside the handle, and a support frame is fixedly connected to the outer wall of the connecting column.

[0010] As a further description of the above technical solution: a gear is rotatably connected inside the support frame, and the gear meshes with the internal rack.

[0011] As a further description of the above technical solution: a double-row rack is fixedly connected inside the support rod, and the double-row rack meshes with the gear.

[0012] As a further description of the above technical solution: a sleeve is fixedly connected to the outer wall of the connecting column, and a fixing block is fixedly connected to the outer wall of the sleeve.

[0013] As a further description of the above technical solution: a support shaft is fixedly connected inside the fixed block, and a rotating rod is rotatably connected to the outer wall of the support shaft, with one bottom end of the rotating rod slidably connected inside the support rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by pulling open the second brush roller to expose the nozzle for spraying, and then closing and locking the second brush roller for painting, the effect of effectively spraying and painting the wall is achieved. This solves the problem that the brush roller needs to pick up a large amount of paint during the painting process, and the paint will flow down the wall, requiring repeated painting of the wall surface, resulting in low painting efficiency, thereby improving the painting efficiency.

[0016] 2. In this utility model, the support rod works in cooperation with the internal rack and gear, connecting column, double rack and rotating rod structure, achieving the effect that the length of the support rod can be adjusted according to the needs. This solves the problem that the length of the support rod is too fixed and cannot be adjusted as needed. When painting walls of different heights, it is necessary to use other tools to climb to higher places, which is a cumbersome process. This improves the applicability of the spraying device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 2-5This utility model provides an embodiment of a spraying device for interior wall decoration, including a support rod 1, which is the basic support structure of the entire device. A connecting rod 2 is fixedly connected inside the support rod 1. A sealing plug 3 is rotatably connected to the outer wall of one end of the connecting rod 2. A spraying pipe 4 is fixedly connected to the outer wall of the sealing plug 3, designed as a sealing structure to prevent leakage of spraying material. A first brush 5 is fixedly connected to the outer wall of the spraying pipe 4, and a second brush 6 is slidably connected to the outer wall of the spraying pipe 4 to achieve flexible adjustment during operation. A nozzle 10 is provided inside the spraying pipe 4. A regulating valve 8 is fixedly connected to one end of the spraying pipe 4 to control the flow rate and pressure of the spraying material. A material extraction pipe 9 is fixedly connected to the input end of the regulating valve 8, which introduces the spraying material from the material tank. A connecting component is provided inside the first brush 5 to connect the first brush 5 and the second brush 6, making it convenient for the operator to paint on the wall. A telescopic component is provided on the outer wall of the support rod 1 to adjust the painting height of the second brush 6.

[0027] The connecting assembly includes a support column 12 and a retaining bead 14. The support column 12 is slidably connected inside the first painting roller 5, and the retaining bead 14 is fixedly connected to one end of the support column 12. A spring 13 is sleeved on the outer wall of the support column 12. One end of the spring 13 is fixedly connected to the outer wall of the retaining bead 14, and the other end of the spring 13 is fixedly connected to the inside of the first painting roller 5. The function of the spring 13 is to provide the necessary elasticity to make the connection between the first painting roller 5 and the second painting roller 6 more stable. A retaining block 11 is fixedly connected to one side of the second painting roller 6. The retaining block 11 engages with the retaining bead 14 to ensure that the two are firmly connected in the working state. A handle 7 is fixedly connected to one end of the second painting roller 6.

[0028] Specifically, when using this spraying device, the operator first needs to pull the handle 7 so that the force can effectively drive the brush roller 2 6 to slide on the outer wall of the spray tube 4. As the brush roller 2 6 slides outward, the nozzle 10 inside the spray tube 4 is gradually exposed to the external environment. At this time, the operator connects to the external feeding device through the extraction pipe 9 and starts the feeding device so that the paint enters the spray tube 4 through the extraction pipe 9 under the action of air pressure, and then sprays the paint evenly on the wall surface through the nozzle 10. After the spraying is completed, the operator needs to slide the brush roller 2 6 back to its original position. At this time, the locking block 11 at one end of the brush roller 2 6 will contact the locking bead 14 inside the brush roller 1 5 to ensure that the contact with the locking bead 14 can effectively transmit force and push the locking bead 14 to move inward. When the first and second painting rollers 5 and 6 are fully connected, the retaining bead 14 is pressed by the retaining block 11, causing the spring 13 connected behind it to contract. This not only increases the firmness of the connection but also reduces the risk of accidental loosening during operation. After the connection is completed, the spring 13 will quickly release the force and rebound, pushing the retaining bead 14 back to its original position, locking it outside the retaining block 11, thus achieving a stable connection. This ensures that the fit between the first and second painting rollers 5 and 6 is tight throughout the spraying process, avoiding uneven or missed spraying of paint. Subsequently, the operator pushes the support rod 1, causing the first and second painting rollers 5 and 6 to rotate and paint on the wall together. The rotation of the first and second painting rollers 5 and 6 can efficiently and evenly cover the wall with paint, significantly improving construction efficiency and painting quality.

[0029] Reference Figure 1 and Figure 6 The telescopic assembly includes a connecting post 16 and a handle 15. The connecting post 16 is slidably connected to the outer wall of the support rod 1 and nested within the outer wall of the support rod 1, allowing it to move axially along the support rod 1 within a certain range. The handle 15 is slidably connected to the outer wall of the connecting post 16, so that the operator can easily adjust the length and height of the telescopic assembly. An internal rack 19 is fixedly connected inside the handle 15, thereby realizing the transmission of force and precise control of position. A support frame 20 is fixedly connected to the outer wall of the connecting post 16, providing additional stability to the assembly. A gear 21 is rotatably connected inside the support frame 20, and the gear 21 meshes with the internal rack 19. A double-row rack 22 is fixedly connected inside the support rod 1, which can improve the overall load-bearing capacity and stability. The double-row rack 22 meshes with the gear 21, thereby achieving the telescopic effect.

[0030] Specifically, when adjusting the length of the support rod 1, the rotating rod 24 needs to be operated first. By rotating the rotating rod 24 clockwise or counterclockwise, the positioning pin at its bottom can be effectively slid out of the support rod 1, thus releasing the fixation of the support rod 1. Next, the support rod 1 can be pulled to adjust its length. During this process, the support rod 1 will not only move linearly, but will also drive the internally connected double-row rack 22 to move synchronously. The structure of the double-row rack 22 is usually composed of a series of parallel teeth, which mesh with the gear 21. When the double-row rack 22 is subjected to external force, its movement will directly affect the meshing gear 21, thereby achieving efficient power transmission. Under the action of force, the gear 21 will rotate inside the support frame 20 and move along the outer wall of the inner rack 19 at the same time. The structural design of the inner rack 19 can stably guide the movement of the gear 21 and prevent it from deviating.

[0031] Reference Figure 1 and Figure 6 A sleeve 18 is fixedly connected to the outer wall of the connecting column 16. A fixing block 23 is fixedly connected to the outer wall of the sleeve 18. A support shaft 17 is fixedly connected inside the fixing block 23. The design of the support shaft 17 ensures the overall stability of the component. A rotating rod 24 is rotatably connected to the outer wall of the support shaft 17, so that the rotating rod 24 can rotate freely inside the support rod 1. One end of the rotating rod 24 is slidably connected inside the support rod 1.

[0032] Specifically, as gear 21 rotates, it pushes support frame 20 to move in the desired direction. Support shaft 17 is connected to the outer wall of support frame 20, and support rod 1 slides inside handle 15. The design of support shaft 17 allows rotating rod 24 to rotate smoothly within fixed block 23, thus ensuring smoother extension of support rod 1. Once support rod 1 is adjusted to the predetermined length, the user only needs to rotate rotating rod 24 back to its original position, so that positioning pin slides back into the corresponding positioning hole inside support rod 1 for fixing, ensuring that support rod 1 will not accidentally loosen or slide during use, thereby achieving the effect of precise adjustment of painting height according to needs.

[0033] Working principle: When using this spraying device, first pull handle 7, causing the brush roller 2 6 to slide against the outer wall of the spray tube 4. This sliding of brush roller 2 6 exposes the nozzle 10 inside the spray tube 4. At this time, the feeding device connected to the extraction pipe 9 delivers paint into the spray tube 4, which is then sprayed onto the wall surface through the nozzle 10. After spraying is complete, slide brush roller 2 6 back to its original position, allowing brush roller 2 6 to retract into the spray tube. When the first and second 6 paint rollers are fully connected, the locking block 11 at one end of the first 5 paint roller will contact the locking bead 14 inside the first 5 paint roller. This causes the locking bead 14 to be stressed, which in turn causes the spring 13 connected to the outer wall to contract. When the first 5 and the second 6 paint rollers are fully connected, the spring 13 is relieved and rebounds, which in turn causes the locking bead 14 to return to its original position and lock itself in place outside the locking block 11. Then, the support rod 1 is pushed, causing the first 5 and the second 6 paint rollers to rotate on the wall. The painting process effectively achieves the effect of spraying and painting on the wall. When the length of the support rod 1 needs to be adjusted, first rotate the rotating rod 24 so that the positioning pin on one side of the bottom slides out from the inside of the support rod 1. Then pull the support rod 1 to move it. At the same time, the support rod 1 will also drive the double-row rack 22 connected inside to move. The double-row rack 22 is forced to drive the gear 21 meshing with it to rotate inside the support frame 20. During the rotation, the gear 21 will also move along the outer wall of the inner rack 19 it meshes with, thereby causing the gear 21 to drive the support frame 20 to move. The support frame 20 is forced to drive the support rod 1 connected to the outer wall to slide inside the handle 15, so that the support rod 1 extends. When the support rod 1 is adjusted to the required length, the rotating rod 24 is turned back so that the positioning pin slides into the corresponding positioning hole inside the support rod 1 for fixing, thereby achieving the effect of adjusting the painting height according to the needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
