Dustproof cover structure inside the hole

Abstract

This invention discloses a dustproof cover structure for ceiling lights, comprising a cover, an adhesive layer, a release liner, and a 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 disposed on the adhesive layer and provides protection for it. One end of the handle can movably extend through the cover, adhesive layer, and release liner. With these components, the cover, in conjunction with the adhesive layer, extends through a ceiling light hole and adheres to the inner side of the ceiling, sealing the cross-section of the light hole and achieving a dustproof effect.

Claims

1. A dust cover structure for an internal hole, comprising: A cap, selected from a geometrical outline and having a predetermined deformable elasticity, further includes a shaft hole formed through the cap; an adhesive layer, assembled on a predetermined end face of the cap; a release paper, disposed on the adhesive layer and forming a protective layer for the adhesive layer; and a pull handle, which can movably extend through the cap, the adhesive layer, and the release paper corresponding to the shaft hole, selectively applying pressure to the cap, having: a buckle portion abutting against the end face of the cap away from the adhesive layer; and a handle portion, one end connected to the buckle portion and the other end extending through the shaft hole, and having deformable flexibility.

2. A dust cover structure for an internal hole, comprising: A cap, selected from a geometric outer contour and having a predetermined deformation elasticity, further includes a shaft hole that penetrates the cap; It also includes a handle that extends through the shaft hole and is pivotally connected to the cover, selectively applying pressure to the cover, and has: a buckle that abuts against a preset end face of the cover; and a handle that is connected at one end to the buckle and extends through the shaft hole at the other end, and has deformability and flexibility.

3. The dust cover structure inside the hole as described in claim 1, wherein the release paper has at least one tear-off loop and is concentrically configured with the shaft hole.

4. The dust cover structure inside the hole as described in claim 1 or 2, wherein the cover material is selected from ethylene-vinyl acetate copolymer of a predetermined thickness.

5. The dust cover structure inside the hole as described in claim 1 or 2, wherein the buckle portion is located away from the end face of the cover, and a reinforcing rib is provided along the outer periphery of the buckle portion.

6. The dust cover structure for the hole as described in claim 1 or 2, wherein the pull handle has a cylindrical section and a plate section at both ends along the extension direction.

7. The dust cover structure inside the hole as described in claim 1 or 2, wherein the pull handle is selected from a strap.

8. The dust cover structure inside the hole as described in claim 1 or 2, wherein the pull handle is selected from the strap profile, and: the buckle has a through hole formed through the buckle and a locking tooth protruding from the wall of the through hole; and the handle is connected at one end to the buckle and extends through the shaft hole, and has a tooth row on a preset end face.
