Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The following description, with reference to the accompanying drawings, describes a hole cover 100 according to an embodiment of the present invention, wherein the hole cover 100 can be used to cover a hole structure in a wall hole or other location to cover the hole structure.

[0037] like Figure 1-Figure 3 As shown, the hole cover 100 according to an embodiment of the present utility model includes: a cover plate 1 and a collar 2.

[0038] Specifically, the cover plate 1 can be a plate-like structure, and the cover plate 1 can be round, square or other shapes. Since hole structures such as wall holes are generally round holes, the cover plate 1 can be a round plate structure.

[0039] The collar 2 is located on one side of the cover plate 1 along its thickness direction. The collar 2 is annular, and can be circular or square, etc. The hole cover 100 with different shaped collars 2 is adapted to the shape of the hole. Generally, the hole structure is circular, and the collar 2 can be circular. One axial end of the collar 2 is connected to the cover plate 1. The collar 2 can be integrally connected to the cover plate 1, for example, as a single piece, or through snap-fit ​​connection or fastener connection, etc., without limitation. Multiple collars 2 are spaced apart along the radial direction of the collar 2.

[0040] In related technologies, the hole cover includes a cover plate and a collar. During installation and use, the collar is inserted into the hole structure such as the wall hole, and the cover plate fits against the wall surface to achieve the purpose of sealing the wall hole. In addition, when a pipe is installed in the wall hole, the pipe is installed on the cover plate and located radially inside the collar.

[0041] In this application, by setting multiple radially spaced collars 2 on one side of the cover plate 1 in the thickness direction, collars 2 of appropriate size can be selected according to the size of the hole structure such as the wall hole. The hole cover 100 is then cut to remove excess collars 2, retaining collars 2 of appropriate size and at least part of the cover plate 1 structure. This better seals the hole structure such as the wall hole and avoids situations where the diameter of the collar 2 does not match the diameter of the wall hole, or problems with the hole cover 100 structure being misplaced during production. In addition, in this application, an opening structure for pipelines to pass through can be provided on the radially inner side of the innermost collar 2. This opening structure can be produced directly at the factory or cut out later.

[0042] Optionally, the hole cover 100 of this application can be a plastic part, which is easy to cut, low in cost, and easy to process.

[0043] According to the embodiment of the present utility model, the hole cover 100 is provided with a plurality of radially spaced collars 2 on one side of the cover plate 1 in the thickness direction. During installation, a collar of appropriate size can be selected for installation and adaptation according to the size of the hole structure such as the wall hole. This achieves installation adaptation for different wall hole sizes, improves the versatility of the hole cover 100, and reduces the problem of misuse or mixing of hole covers 100 of different sizes, which can lead to failure to install properly.

[0044] In some embodiments of this utility model, such as Figure 2 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the cover plate 1 has a through hole 13, which includes multiple sub-holes 131 spaced apart along the circumferential direction of the collar 2. The sub-holes 131 extend along the circumferential direction of the collar 2, and a connecting rib 132 is formed between two adjacent sub-holes 131. A through hole 13 is provided between any two adjacent collars 2. In the radial direction of the collar 2, the portions located on both sides of the through hole 13 are connected by the connecting ribs 132. When cutting, cutting the connecting ribs 132 can separate two adjacent collars 2, which is convenient for cutting. Specifically, by cutting different connecting ribs 132, a collar 2 of a suitable size can be selected to adapt to the installation requirements under different wall hole diameters.

[0045] For example, the size of the hole structure such as the wall hole is adapted to the size of the innermost ring 2 in the radial direction. The outer side of the innermost ring 2 in the radial direction can be cut off to remove the rest of the ring 2 structure, leaving only the innermost ring 2 structure. At the same time, the part of the cover plate 1 structure on the outer side of the innermost ring 2 in the radial direction is retained to prevent the rest of the ring 2 from abutting against the wall and affecting the insertion of the ring 2 into the wall hole, thus affecting the assembly of the hole cover 100.

[0046] For example, the size of the hole structure, such as the wall hole, is adapted to the size of the outermost radial collar 2. When there is no pipe passing through the wall hole, the hole cover 100 structure can be used directly. When there is a pipe passing through the wall hole, at least a portion of the radially inner collar 2 structure can be cut off according to the pipe size to facilitate the passage of the pipe.

[0047] For example, if the dimensions of a wall hole or other hole structure are compatible with the dimensions of a central collar 2, it can be cut radially outward from the collar 2 to prevent it from abutting against the wall and affecting the assembly of the hole cover 100. Additionally, when a pipe passes through the wall hole, at least a portion of the collar 2 radially inward can be cut away according to the pipe dimensions to facilitate pipe passage.

[0048] In some embodiments of this utility model, such as Figure 3 As shown, the cover plate 1 has a through hole 14, which is located radially inside all the sleeves 2. This facilitates the passage of pipelines and avoids cutting the through hole 14 during later installation and use, saving installation time. When using the innermost radial sleeve 2 to fit the wall hole, there is no need to cut the through hole 14 structure. When the other sleeves 2 fit the wall hole but the size of the through hole 14 cannot fit the pipeline, the radially inner sleeve 2 of the fitted sleeve 2 can be cut to obtain a larger opening for the pipeline to pass through.

[0049] In some other embodiments of this utility model, the center of the cover plate 1 is a solid structure, and the radial inner side of the collar 2 located on the radial inner side is also provided with a through hole 13. When using the hole cover 100 structure and needing to open a hole on the radial inner side of the collar 2 located on the radial innermost side, the through hole 13 part can be directly cut, which is convenient for cutting.

[0050] In a specific example of this utility model, such as Figure 2 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, a through hole 13 is provided between any two adjacent collars 2. The radially outer sidewall of the through hole 13 is flush with the inner peripheral wall of the collar 2 located on the radially outer side of the two adjacent collars 2. A through hole 14 is provided on the cover plate 1. The inner peripheral wall of the through hole 14 is flush with the inner peripheral wall of the collar 2 located on the radially innermost side.

[0051] Therefore, when the outer ring 2 of the adapter ring 2 is cut off, a sufficiently large cover plate 1 structure can be retained to seal the wall hole and other structures, preventing the wall hole from being exposed. When the inner ring 2 of the adapter ring 2 is cut off, the adapter ring 2 can better cooperate with the pipeline and other structures, ensuring the reliability of the hole cover 100 in the wall hole.

[0052] In some embodiments of this utility model, such as Figure 2 , Figure 7 and Figure 9 As shown, at least one surface of the connecting rib 132 along the thickness direction of the cover plate 1 is recessed within the cover plate 1. It can be understood that the surface of the connecting rib 132 facing away from the collar 2 along the thickness direction of the cover plate 1 is recessed within the surface of the cover plate 1 facing away from the collar 2, or the surface of the connecting rib 132 facing the collar 2 is recessed within the surface of the cover plate 1 facing the collar 2, or both surfaces of the connecting rib 132 along the thickness direction of the cover plate 1 are recessed within the two surfaces of the cover plate 1 respectively. This allows the thickness of the connecting rib 132 to be less than the thickness of the rest of the cover plate 1, facilitating the cutting of the connecting rib 132.

[0053] exist Figure 6 , Figure 7 , Figure 9 and Figure 10 In the example shown, the side surface of the connecting rib 132 facing away from the collar 2 is recessed into the side surface of the cover plate 1 facing away from the collar 2, and the side surface of the connecting rib 132 facing the collar 2 is flush with the side surface of the cover plate 1 facing the collar 2.

[0054] In some embodiments of this utility model, the outer diameter of the collar 2 is 50mm-120mm. The outer diameters of the multiple collars 2 are different. Along the radial outward direction of the cover plate 1, the outer diameters of the multiple collars 2 gradually increase, so that the outer diameters of the multiple collars 2 meet the requirements of 50mm-120mm, which can meet the needs of most wall hole sizes and improve the application range of the hole cover 100.

[0055] In some embodiments of this utility model, the number of collars 2 is 3-6. This allows for the provision of 3-6 different sizes of collars 2, enabling the hole cover 100 structure to adapt to 3-6 different wall hole sizes, increasing the application range of the hole cover 100, and avoiding increased costs due to a larger number of collars 2.

[0056] For example, in Figure 1In the example shown, ring 2 consists of three rings spaced at intervals.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the end of the collar 2 facing away from the cover plate 1 has multiple notches 23, which are spaced apart in the circumferential direction of the collar 2. This allows the collar 2 structure to undergo small deformations. When the size of the collar 2 is slightly larger than the size of the wall hole, it can be fitted into the wall hole by deforming the collar 2 radially inward, which facilitates the assembly of the hole cover 100 and improves the reliability of the assembly between the hole cover 100 and the wall hole.

[0058] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the cover plate 1 includes a first cover plate 11 and a second cover plate 12, which are snap-fitted together. Each collar 2 includes a first collar 21 on the first cover plate 11 and a second collar 22 on the second cover plate 12, which are joined together to form a ring. It can be understood that the hole cover 100 is a split two-part structure. During installation, the two halves of the split structure are snapped together with the pipes outside the wall hole, and then the hole cover 100 is pressed onto the wall hole, facilitating assembly between the hole cover 100 and the pipes. Figure 5 , Figure 6 and Figure 7 Only the structure of the first cover plate 11 and the first collar 21 is shown.

[0059] Furthermore, the first cover plate 11 and the second cover plate 12 are connected by a snap-fit ​​structure 3. Snap-fit ​​structures 3 are provided between adjacent collars 2 and on the radially outermost collar 2. This ensures that the first cover plate 11 and the second cover plate 12 can still be reliably connected after some collars 2 are cut, guaranteeing the reliability of the hole cover 100 structure.

[0060] Optionally, the snap-fit ​​structure 3 includes a first snap-fit ​​portion 31 and a second snap-fit ​​portion 32, such as... Figures 6-11 As shown, the first snap-fit ​​portion 31 has a snap-fit ​​opening 311 with an opening 312. The two side walls opposite to the snap-fit ​​opening 311 have limiting protrusions 313. The second snap-fit ​​portion 32 includes a snap-fit ​​portion 321 and a limiting portion 322. One end of the snap-fit ​​portion 321 is connected to the cover plate 1, and the other end is connected to the limiting portion 322. The snap-fit ​​portion 321 is adapted to be snapped into the snap-fit ​​opening 311. The limiting protrusions 313 are used to limit the snap-fit ​​portion 321 to prevent it from coming out of the opening 312. The first snap-fit ​​portion 31 is located between the limiting portion 322 and the cover plate 1. The limiting portion 322 is used to limit the first snap-fit ​​portion 31 to prevent the first snap-fit ​​portion 31 and the second snap-fit ​​portion 32 from disengaging in the thickness direction of the cover plate 1.

[0061] In addition, the first cover plate 11 has a first snap-fit ​​part 31 at one end of the splicing line between the first cover plate 11 and the second cover plate 12, and a second snap-fit ​​part 32 at the other end. The second cover plate 12 has a first snap-fit ​​part 31 at one end of the splicing line between the first cover plate 11 and the second cover plate 12, and a second snap-fit ​​part 32 at the other end. The structure of the second cover plate 12 and the first cover plate 11 can be exactly the same, thereby saving mold costs.

[0062] Of course, this utility model is not limited to this. The hole cover 100 can also be an integral part, which can simplify the assembly process of the hole cover 100. When the hole cover 100 is installed and used, the pipeline can be inserted into the opening in the middle of the hole cover 100 and connected to other components.

[0063] In some embodiments of this utility model, the outer periphery of the cover plate 1 has a flange 15 bent toward the collar 2, which can increase the structural strength of the cover plate 1.
