Description

Technical Field

[0001] This utility model relates to the technical field of construction machinery, specifically a coating device for interior decoration. Background Technology

[0002] Paint is an essential material in interior decoration. For large walls, paint rollers are usually used to paint, which greatly improves work efficiency. Roller painting can quickly cover large areas of walls or ceilings. Especially after connecting an extension rod, it can easily paint high places, reducing the time spent on scaffolding or ladders, making it suitable for large-area construction.

[0003] However, existing paint rollers have a fixed length. For large walls, multiple coats are needed to complete a certain area. If a longer roller is used to improve painting efficiency, the increased length will make it difficult to handle details later on, thus hindering the use of the paint roller. Therefore, we offer a paint application device for interior decoration to solve these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a coating device for interior decoration. Through the cooperation of a central rod, a second central rod, a fixed rod, and a rubber ring, the two rollers can be fixed together by inserting the fixed rod into the fixed cylinder and securing the rubber ring inside the rubber groove. This improves the efficiency of the roller brush. When dealing with details, only the remaining rollers need to be disassembled. This solves the problem that existing paint rollers have a fixed length, and for some large walls, multiple coats are required to complete a certain area. If a longer roller is used to improve painting efficiency, the longer roller will be inconvenient for handling details, making it difficult to use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a coating device for interior decoration, comprising a central rod 1, a rotating cylinder 1 slidably connected to the outer surface of the central rod 1, a central rod 2 clamped to one end of the central rod 1, a rotating cylinder 2 slidably connected to the outer surface of the central rod 2, a through hole at one end of the rotating cylinder 1, and a through rod fixedly connected to one end of the rotating cylinder 2, the outer surface of the through rod being slidably connected to the inner wall of the through hole;

[0008] One end of the first central rod is fixedly connected to a fixed cylinder, and one end of the second central rod is fixedly connected to a fixed rod. A rubber ring is fixedly connected to the outer surface of the fixed rod. A rubber groove is opened inside the fixed cylinder, and the rubber ring is stuck inside the rubber groove. One end of the fixed rod is fixedly connected to a limiting plate. A limiting groove is opened on the outer surface of the fixed cylinder, and the outer surface of the limiting plate is slidably connected to the inner wall of the limiting groove.

[0009] Furthermore, a retaining ring is fixedly connected to the outer surface of the central rod, and a retaining groove is provided on the inner wall of the rotating cylinder. The outer surface of the retaining ring is slidably connected to the inner wall of the retaining groove.

[0010] Furthermore, a roller surface is slidably connected to the outer surface of the rotating drum, and the roller surface is a detachable roller surface.

[0011] Furthermore, a protrusion is fixedly connected to the outer surface of the rotating drum, and a groove is formed on the inner wall of the drum surface. The outer surface of the protrusion is slidably connected to the inner wall of the groove.

[0012] Furthermore, a screw is threadedly connected to the outer surface of the roller surface, the outer surface of the screw is threadedly connected to the outer surface of the rotating drum, and nuts are threadedly connected to both ends of the screw.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this paint device for interior decoration has the following advantages:

[0017] I. This paint device for interior decoration, through the cooperation of center rod one, center rod two, fixing rod and rubber ring, allows for the fixing of two rollers together by inserting the fixing rod into the fixing cylinder and locking the rubber ring into the rubber groove. This process, repeated, increases the lateral length of the rollers and improves the efficiency of the paint roller. When dealing with details, only the remaining rollers need to be disassembled, leaving only one. This solves the problem that existing paint rollers have a fixed length, and for large walls requiring multiple coats to complete a certain area, using longer rollers to improve painting efficiency can be inconvenient for subsequent details, making it difficult to handle.

[0018] II. This paint device for interior decoration, through the cooperation between the rotating drum, the protrusion, the roller surface and the screw, when using the device, when it is necessary to replace the roller surface, the screw is removed and the roller surface is slid out from the outer surface of the rotating drum. At this time, the protrusion will slide from the inner wall of the groove, and the roller surface can be removed and replaced separately. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figure 1-7 As shown, this utility model provides a technical solution: a coating device for interior decoration, including a central rod 1, a rotating cylinder 2 slidably connected to the outer surface of the central rod 1, a handle 20 fixedly connected to one end of the rotating cylinder 2, an anti-slip strip 21 fixedly connected to the outer surface of the handle 20, the anti-slip strip 21 can increase the friction with the hand, making it easier for workers to use, and a roller surface 15 slidably connected to the outer surface of the rotating cylinder 2, the roller surface 15 being a detachable roller surface 15, the roller surface 15 being made of high-elasticity polyurethane sponge to ensure uniform coating adsorption.

[0030] A retaining ring 13 is fixedly connected to the outer surface of the center rod 1. A retaining groove 14 is provided on the inner wall of the rotating drum 2. The outer surface of the retaining ring 13 is slidably connected to the inner wall of the retaining groove 14. When the roller brush is in operation, the rotating drum 2 will slide on the outer surface of the center rod 1, and the retaining ring 13 will slide on the inner wall of the retaining groove 14. The retaining ring 13 is provided to prevent the rotating drum 2 from moving left and right when rotating. A protrusion 16 is fixedly connected to the outer surface of the rotating drum 2. A groove 17 is provided on the inner wall of the roller surface 15. The outer surface of the protrusion 16 is slidably connected to the inner wall of the groove 17. The roller surface 15 can be quickly replaced to adapt to different paint viscosities, such as latex paint and waterproof paint, thereby reducing maintenance costs.

[0031] One end of the center rod 1 is snapped with a center rod 2 3. Both the center rod 1 and the center rod 2 3 are made of 304 stainless steel and the surface is sandblasted to enhance wear resistance and rust prevention. The outer surface of the center rod 2 3 is slidably connected to a rotating cylinder 2 4. One end of the rotating cylinder 2 4 is provided with an installation groove 22. A rubber cover plate 23 is snapped into the inside of the installation groove 22. The rubber cover plate 23 is divided into two parts: one part is a deformable rubber ring with an annular concave-convex shape, and the other part is a circular plate. The shape of the installation groove 22 matches the shape of the rubber ring, and it can be embedded in the inside of the installation groove 22.

[0032] One end of the rotating cylinder 2 has a through hole 5, and one end of the rotating cylinder 4 is fixedly connected to a through rod 6. The rotating cylinders 2 and 4 are lined with polytetrafluoroethylene coating, which allows for smooth sliding and corrosion resistance. The outer surface of the through rod 6 is slidably connected to the inner wall of the through hole 5.

[0033] One end of the central rod 1 is fixedly connected to a fixed cylinder 7, and one end of the central rod 3 is fixedly connected to a fixed rod 8. A rubber ring 9 is fixedly connected to the outer surface of the fixed rod 8. A rubber groove 10 is opened inside the fixed cylinder 7. The rubber ring 9 can deform to a certain extent, so that it can be inserted into the interior of the rubber groove 10. The rubber ring 9 fills the interior of the rubber groove 10. Without pulling force, the rubber ring 9 will not come out of the rubber groove 10. The rubber ring 9 is stuck inside the rubber groove 10. One end of the fixed rod 8 is fixedly connected to a limiting plate 11. A limiting groove 12 is opened on the outer surface of the fixed cylinder 7. The outer surface of the limiting plate 11 is slidably connected to the inner wall of the limiting groove 12.

[0034] The outer surface of the roller surface 15 is threaded with a screw 18, and the outer surface of the screw 18 is threaded with the outer surface of the rotating drum 2. Nuts 19 are threaded at both ends of the screw 18. When the roller surface 15 needs to be replaced, the screw 18 is removed and the roller surface 15 is slid out from the outer surface of the rotating drum 2. At this time, the protrusion 16 will slide out from the inner wall of the groove 17, and the roller surface 15 can be disassembled and replaced separately.

[0035] Working principle: When using the rollers, first align the limiting plate 11 with the limiting groove 12, then insert the fixing rod 8 into the fixed cylinder 7. The rubber ring 9 will deform and be locked inside the rubber groove 10, and the limiting plate 11 will also be located inside the limiting groove 12. The center rod 1 and center rod 3 can be connected together. When aligning the limiting plate 11 with the limiting groove 12, the through rod 6 will also be inserted into the through hole 5, connecting the rotating cylinder 2 and rotating cylinder 4. When rotating cylinder 2 rotates, rotating cylinder 4 will be driven to rotate through the through rod 6. During painting, rotating cylinder 2 and rotating cylinder 4 should be kept in sync. Finally, the rubber cover plate 23 is locked inside the mounting groove 22. To prevent paint from entering the interior of the second rotating drum 4, when a third roller needs to be installed, install them sequentially in this manner. When the roller surface 15 needs to be replaced, remove the screw 18 and slide the roller surface 15 out from the outer surface of the first rotating drum 2. At this time, the protrusion 16 will slide out from the inner wall of the groove 17. The roller surface 15 can be disassembled separately for cleaning. When using this device, dip the outer surface of the roller surface 15 in paint and roll it up and down on the wall. The roller surface 15 drives the first rotating drum 2 to rotate on the outer surface of the central rod 1. The central rod 1 is aligned with the central rod 2 3. The first rotating drum 2 is aligned with the second rotating drum 4 through the through rod 6, and the roller is rolled on the wall to improve the rolling efficiency.
