Description

Dust cover structure inside the hole Technical Field

[0001] This work relates to the technical field of building materials, and in particular to a dustproof cover structure inside a hole. Prior Technology

[0002] For interior decoration projects, taking the ceiling as an example, several light holes will be opened on the ceiling partition, and the ceiling partition will be ground, repaired and painted.

[0003] When interior decoration or renovation work is underway, especially during ceiling installation and light fixture installation, dust and fine particulate matter generated at the construction site often seep into the internal structure of the ceiling through the light fixture holes. This not only affects the quality of the building but also poses a potential threat to the indoor air quality and the health of the residents. Dust infiltration is a phenomenon that is often overlooked but should not be underestimated.

[0004] First, this dust enters the ceiling cavity with the airflow and remains inside the ceiling for a long time, forming a dust accumulation area. After construction is completed, this dust cannot be naturally discharged, becoming a hidden source of uncleanliness inside the ceiling.

[0005] Gaps often exist between light fixtures and the ceiling. If these gaps are not properly sealed or filled, airflow within the ceiling can carry dust through them into the indoor air, creating a continuous dust diffusion. Furthermore, the complex structure of the ceiling cavity itself easily creates dust traps, which are easily stirred up by wind and movement, increasing the concentration of suspended particles (such as PM2.5 and the finer PM1.0) and further polluting the indoor air.

[0006] The presence of this type of dust not only causes ceilings and light fixtures to be covered in a layer of dust, affecting aesthetics and lighting effects, but also has long-term health consequences for residents. Inhaling these particulate matter can trigger allergic reactions, respiratory diseases, and even exacerbate chronic conditions such as asthma. The impact of this dust is particularly pronounced for individuals with weakened immune systems. Especially in modern, enclosed, and poorly ventilated indoor spaces, dust concentrations can easily accumulate, leading to a decline in indoor air quality.

[0007] In addition, during ceiling construction, light holes are often cut in the wrong place. In this case, it is necessary to cut an extra bracket across the light hole as a support to lock the ceiling panels in place and to seal the light hole. Summary of the Invention

[0008] In view of the problems and shortcomings of the prior art, the main purpose of this invention is to provide a dust cover structure inside the hole, which overcomes the above-mentioned shortcomings through structural design.

[0009] In accordance with the aforementioned objectives, this invention discloses a dustproof cover structure for ceiling light holes, comprising a cover, an adhesive layer, a release liner, and a pull handle. The cover has a pre-set deformable elasticity and a axial hole. The adhesive layer is assembled onto a pre-set end face of the cover. The release liner is placed on the adhesive layer and provides protection for it. One end of the pull handle can movably extend through the cover, adhesive layer, and release liner. Composed of the above components, the cover, in conjunction with the adhesive layer, extends through the ceiling light hole and adheres to the inner side of the ceiling, sealing the cross-section of the light hole and achieving the intended dustproof effect.

[0021] The following description, with reference to the relevant drawings, further illustrates the embodiment of the dust cover structure within the hole of this invention. Various objects in the embodiments are depicted according to the scale, dimensions, deformation, or displacement suitable for illustration, rather than being drawn to the scale of actual components; this is stated above. Furthermore, components with identical or symmetrical arrangements in the remaining embodiments are represented by the same numbers. Additionally, directional terms such as "front," "back," "left," "right," "up," "down," "inner," and "outer" in the descriptions of the embodiments listed below are used according to the specified view direction and should not be construed as limiting the scope of this invention.

[0022] Please refer to Figures 1 to 6 for the implementation of the dust cover inside the hole in this invention, which includes a cover 10, an adhesive layer 20, a release paper 30, and a pull handle 40.

[0023] The aforementioned cover 10 is made of a geometrically shaped outer contour material with a preset deformation (bending) elasticity, and has a central axial hole 11 that penetrates the cover 10. In practice, the material of the cover 10 is selected from ethylene-vinyl acetate copolymer (EVA) of a preset thickness.

[0024] The aforementioned adhesive layer 20 is provided on the preset end face of the cover 10 to provide an adhesive function. In practice, the adhesive layer 20 can be selectively omitted and applied by the user to the cover 10 or the ceiling 50 during construction.

[0025] The release paper 30, applied over the adhesive layer 20, provides anti-stick protection and has a through-hole 31 formed by the concentric shaft hole 11 penetrating through the release paper 30. The release paper 30 further includes at least one easy-tear loop 32, concentrically arranged with the shaft hole 11, facilitating selective removal of part or all of the release paper 30 by the user, exposing part or all of the adhesive layer 20. In practice, the release paper 30 can be omitted to match the adhesive layer 20.

[0026] The aforementioned handle 40 has one end that can movably extend through the cover 10, the adhesive layer 20, and the release paper 30, and has a buckle portion 41 and a handle portion 42 connected in series.

[0027] The buckle 41 has a preset profile at one end that abuts against the preset end face of the cover 10, is positioned away from the adhesive layer 20, and exerts a drag force on the cover 10. The other end of the buckle 41 is provided with a reinforcing rib 411, which is erected along the outer periphery of the buckle 41 on the preset end face to improve the structural rigidity of the buckle 41 and prevent deformation under stress.

[0028] The handle 42 is connected to the buckle 41 at one end and is configured to pass through the shaft hole 11 at the other end, providing a pull for the user. In practice, the handle 42 has a preset deformation and flexibility capability to avoid interfering with the user's construction operation.

[0029] The aforementioned handle 42 further comprises a cylindrical segment 421 and a plate-shaped segment 422 at both ends along its extension direction. The cylindrical segment 421 provides structural strength for connection with the buckle 41, while the plate-shaped segment 422 provides enhanced deformation and bending characteristics. In practice, the free end of the plate-shaped segment 422 further has a pointed profile to facilitate passing through the shaft hole 11.

[0030] Therefore, the above is an introduction to the components and assembly method of the dust cover inside the hole in a preferred embodiment of the present invention. The operating characteristics of the embodiment of the present invention will be introduced below.

[0031] During construction, if you want to prevent dust from entering the light hole 51 of the ceiling 50, first select a cover 10 with a cross-sectional area larger than the light hole 51, deform the cover 10 by squeezing it, and then insert it through the light hole 51 and place it on the inner side of the ceiling 50.

[0032] After removing the release paper 30, use the pull handle 40 to stick and fix the cover 10 to the inside of the ceiling 50. Pull the handle 42 to make the buckle 41 apply force to the cover 10, ensuring that the adhesive layer 20 is tightly attached to the ceiling 50, so as to completely seal the cross section of the light hole 51.

[0033] This effectively prevents dust generated during indoor construction from entering the interior of the ceiling 50, keeping the inside of the ceiling 50 clean.

[0034] In addition, when working on the ceiling 50 (e.g., sanding and painting), the handle 42 is flexible and can be deformed to prevent the cover 10 from shifting due to collisions by the user or tools. The handle 42 can also be pushed back along the shaft hole 11 to reduce its exposed length.

[0035] After construction is completed, push the top cover 10 to separate from the ceiling 50, then squeeze the cover 10 to deform it and remove it from the light hole 51, making room for the light fixture assembly.

[0036] Alternatively, the cover 10 in the preset position can be removed to serve as the air inlet and outlet of the ceiling 50. High-pressure air (or dust-generating air) can be introduced through the air inlet, and a vacuuming device can be set up with the air outlet to further clean the inside of the ceiling 50 and remove residual dust from the inside of the ceiling 50.

[0037] Please refer to Figure 7. If the position of the light hole 51 is incorrect during the construction of the ceiling 50, the cover 10 can be glued to the inside of the corresponding light hole 51 as a cross-sectional support. The ceiling scrap 53 cut off when the light hole 51 is misaligned can be glued to the cover 10. With the filler A set along the outline of the ceiling scrap 53, the incorrect light hole 51 can be quickly filled. This increases the convenience of construction, and by using the cover 10 as a support, its material, ethylene-vinyl acetate copolymer (EVA), effectively blocks the transmission of noise.

[0038] Please refer to Figures 8 to 10. The pull handle 40' can be selected from straps or similar structural specifications during implementation, reducing the construction cost of the pull handle 40' and achieving the expected purpose of applying force to the cap 10. The buckle portion 41' of the pull handle 40' further includes a through hole 412 formed through the buckle portion 41' and a locking tooth 413 protruding from the wall of the through hole 412.

[0039] The handle 42' has a pre-set end face that further includes a tooth row 423. After the free end of the handle 42' is inserted through the through hole 412, the tooth row 423 and the locking tooth 413 form a locking. Then, the free end of the handle 42' is inserted through the shaft hole 11 to increase the contact area when the pull handle 40' applies force to the cover 10.

It is not intended to limit the scope of the embodiments of this invention. Equivalent changes made by those skilled in the art based on this invention, as well as changes well known to those skilled in the art, should still fall within the scope of this invention.
