Description

Technical Field

[0001] This utility model relates to the field of decoration tools, specifically a tool for sanding corners of walls. Background Technology

[0002] During the renovation process, corner sanding is a very important step in wall decoration. After the putty is applied, there may be minor imperfections in the corners, such as joints and pinholes. Sanding can solve these problems, making the corners more uniform, smooth and flat. This helps to ensure even application of latex paint and avoids problems caused by differences in surface structure, such as local color differences in paint.

[0003] Currently, sandpaper is commonly used to sand corners. The operator presses the sandpaper and moves it along the wall on both sides of the corner to sand it. This method of sanding corners is obviously inconvenient. In addition, because the area that fingers or palms can press is limited, the actual effective sanding area of ​​a sandpaper is limited, resulting in low work efficiency.

[0004] Chinese utility model patent with publication number CN210997865U discloses a corner sanding device for interior decoration. According to its disclosure, the corner sanding auxiliary device mainly includes a fixed plate and a movable plate rotatably connected to the upper part of the fixed plate. After the movable plate is flipped down 90°, the corner of the wall at 90° can be sanded, thereby replacing the above-mentioned method of sanding by manually pressing sandpaper, thus improving work efficiency.

[0005] However, in actual use, after the movable plate is flipped down 90°, it is only supported and limited by the fixing block at the rear end of the fixed plate and the first fixed plate. There is a lack of effective fixing means for the movable plate. In addition, the support rod is connected to the rear end of the fixed plate, which causes the sandpaper (the sanding part) to be far away from the end of the support rod (the part where force is applied). As a result, it is difficult to effectively apply pressure to the sandpaper, and the sandpaper at the front end of the fixed plate and the movable plate will be unstable in terms of force, resulting in shaking or wobbling, which will affect the sanding effect and sanding quality of the corner. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects and deficiencies of the existing technology and provide a tool for sanding corners. When held, it can apply stable, even and continuous pressure to the sandpaper on both sides to ensure the sanding effect and quality of the corners.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A tool for sanding corners of walls includes a handle and two side panels. The handle includes a grip and a horizontal plate integrally connected to the front end of the grip. The two side panels are integrally connected to the front side of the horizontal plate, and the two side panels form an angle with each other. Sandpaper connecting pieces are fixedly connected to the surface of the two side panels for detachably connecting sandpaper.

[0009] Furthermore, one side of the sandpaper connecting piece is an adhesive surface and is adhered to the surface of the panel, while the other side of the sandpaper connecting piece is a roughened surface.

[0010] Furthermore, one side of the sandpaper is a napped side and is adhered to the bristle side.

[0011] Furthermore, the gripping part is a profile with an Ω-shaped cross-section and a hollow interior.

[0012] Furthermore, the surfaces of the protruding parts on both sides of the grip are provided with anti-slip textures.

[0013] Furthermore, one end of each of the two side panels is integrally connected to the two ends of the front side of the horizontal plate, and the other ends of the two side panels are integrally connected to each other.

[0014] Furthermore, the included angle between the two side panels is 90°.

[0015] Furthermore, a first reinforcing rib is integrally connected between the two side panels, and a second reinforcing rib is integrally connected between the cross plate and the first reinforcing rib.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a panel at an angle to each other on the front side of the horizontal handle, with a sandpaper connecting piece fixedly connected to the surface of the panel. The sandpaper is detachably attached to the surface of the sandpaper connecting piece, i.e., adhered to the surface of the sandpaper connecting piece, so that the entire sandpaper is securely fixed to the panel. This ensures that the sandpaper will not misalign or loosen when rubbing against the wall surface on both sides of the corner. The worn sandpaper can be removed (torn off) and replaced. When the operator holds the horizontal handle, a stable, even, and continuous pressing pressure can be applied to the sandpaper, thereby ensuring the sanding effect and quality of the corner, and it is convenient and easy to use.

[0018] Figure 1 This is a schematic diagram of the structure of this utility model.

[0019] Figure 2 This is a schematic diagram of the structure of the horizontal handle and the panel in this utility model. Detailed Implementation

[0020] 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.

[0021] See Figure 1 , 2 A tool for sanding corners of walls includes a handle 1 and two side panels 3. The handle 1 includes a grip 11 and a horizontal plate 12 integrally connected to the front end of the grip 11. The two side panels 3 are integrally connected to the front side of the horizontal plate 12, and the two side panels 3 form an angle with each other. Sandpaper connecting pieces 4 are fixedly connected to the surface of the two side panels 3 for detachably connecting sandpaper 2.

[0022] In this invention, one side of the sandpaper connecting piece 4 is the adhesive side and is adhered to the surface of the panel 3, while the other side of the sandpaper connecting piece 4 is the bristle side.

[0023] In this invention, one side of the sandpaper 2 is a napped side and is adhered to the bristle side.

[0024] Thus, the sandpaper 2 is glued to the sandpaper connecting piece 4, thereby securing the entire sandpaper 2 firmly to the two side panels 3, and making it detachable.

[0025] Correspondingly, the other side of sandpaper 2 is a sanding surface covered with abrasive grains, which is used to sand the wall surface on both sides of the corner.

[0026] In this utility model, the gripping part 11 is a profile with an Ω-shaped cross section and a hollow interior.

[0027] Therefore, after the operator holds the handle 1, the pad of the thumb and the pads of the other four fingers respectively contact the surfaces of the recessed parts on both sides of the grip part 11 to grip the grip part 11 tightly, so as to apply pressure to the sandpaper 2 stably and continuously.

[0028] In this utility model, the surfaces of the protruding parts on both sides of the grip 11 are provided with anti-slip textures 5 to increase friction between the fingertips and the palm, thereby preventing slippage.

[0029] In this utility model, one end of each side panel 3 is integrally connected to the two ends of the front side of the horizontal plate 12, and the other ends of the side panels 12 are integrally connected to each other, with the included angle between the side panels being 90°.

[0030] This allows the two side panels 3 and the horizontal plate 12 to form a stable right-angled triangle structure, which is beneficial for sanding the wall surface on both sides of the corner (right angle) and for the operator to apply stable, even and continuous pressure to the sandpaper 2.

[0031] In this utility model, a first reinforcing rib 6 is integrally connected between the two side panels 3, and a second reinforcing rib 7 is integrally connected between the horizontal plate 12 and the first reinforcing rib 6, thereby supporting and reinforcing the horizontal handle 1 between the two side panels 3 and the horizontal plate 12.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] When using, first attach the napped side of the two sandpapers 2 to the corresponding burr side of the sandpaper connecting piece 4 on both sides to securely fix the entire sandpaper 2 to the two side panels 3, ensuring that the sandpaper 2 will not misalign or loosen when rubbing against the wall surface on both sides of the corner.

[0034] Then, the operator holds the handle 1, at which point the pad of the thumb and the pads of the other four fingers respectively contact the surfaces of the recessed parts on both sides of the grip 11, thereby gripping the grip 11 tightly so as to apply pressure to the sandpaper 2 on both sides stably, evenly and continuously.

[0035] The operator holds the horizontal handle 1 and applies stable, even and continuous pressure to the sandpaper 2. By moving the horizontal handle 1, the sandpaper 2 can be moved along the wall surface on both sides of the corner to sand the corner, ensuring the sanding effect and quality of the corner.

[0036] When sandpaper 2 becomes worn, it can be replaced by removing (tearing off) the worn sandpaper.
