Description

Technical Field

[0001] This utility model relates to the field of decoration tools technology, specifically to a dustproof device for decoration holes. Background Technology

[0002] During building decoration construction, after the plasterboard on walls and ceilings is installed, various decorative openings such as light fixture mounting holes and ventilation holes are often needed for subsequent equipment installation or pipeline laying. During the interval between leaving these decorative openings and actual use, especially when subsequent finishing processes such as painting or spraying the ceiling plasterboard are carried out, dust, paint particles, and plaster debris in the air can easily enter the openings and the internal cavities of the wall through the unsealed openings. These impurities not only contaminate the internal space of the plasterboard but may also fall off due to vibrations during subsequent use, affecting the cleanliness of the indoor environment.

[0003] Currently, to address the dust prevention needs of such decorative openings during the construction phase, existing technologies often use plastic baffles as temporary shielding tools, securing them by pressing the edges of the plastic baffles into the decorative openings. However, this method has significant technical drawbacks: the plastic baffles are fixed solely by the frictional force between their edges and the opening wall, making them highly susceptible to loosening or even detachment under the vibrations of painting operations, personnel contact, or airflow disturbances, resulting in shielding failure and ineffective prevention of dust entry.

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] Example 1

[0046] This utility model provides a dustproof device for decorative openings, such as... Figures 1 to 9 As shown, the dustproof device for the decoration hole includes a support 1 and a shield 2.

[0047] The support member 1 has a limiting part 11, and the shielding member 2 is connected to the support member 1. The shielding member 2 is adapted to the decoration hole 31 on the decoration panel 3.

[0048] During installation, the support member 1 is connected to the blocking member 2, and then the support member 1 is passed through the decoration hole 31, and the bottom surface of the limiting part 11 is made to abut against the top surface of the decoration panel 3. At this time, the blocking member 2 blocks the decoration hole 31.

[0049] The installation process is extremely convenient, requiring only simple positioning and pressing.

[0050] During the dustproof process, the limiting part 11 plays a limiting role, which can effectively limit the axial installation position of the dustproof device, making it stable and not easy to loosen or fall off. Together with the shielding part 2, it can effectively shield the decoration hole 31, and block dust, paint particles and other impurities from entering the decoration hole 31 and the internal cavity to the greatest extent, resulting in a significant dustproof effect.

[0051] Meanwhile, in practical applications, a dustproof device of the corresponding specification of the decoration hole 31 can be selected and installed according to the actual specifications of the decoration hole 31, which is flexible and versatile.

[0052] As an optional implementation, the limiting part 11 is configured as a limiting block, which is integrally configured with the support member 1; the bottom surface of the limiting block abuts against the top surface of the decorative panel 3.

[0053] Support component 1 adopts an integrated structure, which simplifies the production process and saves production costs.

[0054] As an optional implementation, the support member 1 is configured as a support bar, which includes a first strip-shaped body 13, a second strip-shaped body 14, and a third strip-shaped body 15 integrally formed along a top-to-bottom direction.

[0055] The lengths of the first strip body 13 along the horizontal plane, the third strip body 15 along the horizontal plane, and the second strip body 14 along the horizontal plane decrease sequentially.

[0056] During use, the bottom surfaces of the two end sections of the first strip body 13 abut against the top surface of the decorative panel 3, thus forming a limiting part 11 in the end sections of the first strip body 13.

[0057] The second strip body 14, which connects the first strip body 13 and the third strip body 15, has the shortest length, so that a gap can be formed between the first strip body 13 and the third strip body 15. During the installation process, it is easy to squeeze the first strip body 13 to make it undergo adaptive bending deformation, so that it can easily abut against the top side of the decorative panel 3, making the installation operation more labor-saving and convenient.

[0058] As an optional implementation, the length of the second strip body 14 along the horizontal plane matches the inner diameter of the decoration hole 31; thus, the outer peripheral wall of the second strip body 14 can abut against the inner wall of the decoration hole 31, thereby limiting its radial installation position. The support member 1 combines axial and radial limiting to make the installation more stable.

[0059] As an optional implementation, the end face of the second strip body 14 is set as an arc surface, and the curvature of the arc surface is adapted to the inner wall of the decoration hole 31. In this way, during installation, the arc surface fits into the inner wall of the decoration hole 31, making the radial limiting force more balanced.

[0060] As an optional implementation, the shielding member 2 is configured as a shielding plate, and a first connecting post 12 is provided on the side of the support bar facing the shielding plate, and a second connecting post 22 is provided on the side of the shielding plate facing the support bar, with the first connecting post 12 and the second connecting post 22 connected together.

[0061] Furthermore, the first connecting post 12 is inserted into the second connecting post 22; the diameter of the shielding plate is adapted to the inner diameter of the decoration hole 31. In use, the shielding plate is inserted into the decoration hole 31, and its outer peripheral wall can press against the inner wall of the decoration hole 31, further improving the installation stability and dustproof effect.

[0062] Specifically, the second connecting post 22 has an axial groove that matches the first connecting post 12, and the first connecting post 12 is inserted into the groove, with the two being an interference fit.

[0063] As an optional implementation, both the support member 1 and the shielding member 2 are made of elastic material.

[0064] During installation, an external force is applied to the support 1 and the shield 2, which causes them to deform adaptively, thus facilitating their installation. After installation, the external force is removed, and the support 1 and the shield 2 return to their initial state, thereby ensuring the shielding effect on the decoration hole 31.

[0065] Specifically, both the support component 1 and the shielding component 2 are made of plastic.

[0066] As an optional implementation method, such as Figure 15 As shown, the bottom of the shield 2 is provided with a gripping part 21 for human hand gripping.

[0067] In practical applications, users can directly pinch the dustproof device for decorative holes, which facilitates disassembly and assembly. The dustproof device for decorative holes with pinching part 21 is suitable for thicker decorative boards 3.

[0068] Optionally, the pinching part 21 is configured as a pinching protrusion, and the opposite side walls of the pinching protrusion are provided with grooves to further facilitate pinching. In actual application, the bottom surface of the pinching protrusion is not lower than the bottom surface of the decorative board 3, so as not to affect the subsequent decoration process such as painting of the decorative board.

[0069] Example 1 is mainly applicable to lamp holes, such as Figure 16 As shown, Figure 16 A schematic diagram showing the dimensions of the dustproof device for the decorative hole, which is adapted to a lamp tube with a diameter of 75mm.

[0070] Example 2

[0071] The difference between Example 2 and Example 1 is that:

[0072] like Figures 10 to 14 As shown, the first connecting post 12 and the second connecting post 22 are threaded together; the diameter of the shielding plate is larger than the inner diameter of the decoration hole 31, and the top surface of the shielding plate abuts against the bottom surface of the decoration panel 3.

[0073] In actual use, by rotating the shield 2, not only can its axial relative position be adjusted, but it can also ensure that it is tightly pressed against the bottom surface of the decorative panel 3, thus ensuring the dustproof effect.

[0074] Specifically, the first connecting post 12 is provided with external threads, and the second connecting post 22 is provided with a threaded hole along the axial direction that is adapted to the external threads. The first connecting post 12 is threadedly connected to the second connecting post 22.

[0075] Example 2 is mainly applicable to ceiling decoration openings. After the decoration is completed, the shielding part 2 seals the ceiling decoration opening. For aesthetic reasons, Example 2 may not have a pinching part 21.
