Description

Technical Field

[0001] This utility model relates to the field of furniture connection structure technology, and in particular to an integrated pre-embedded quick-install hinge moisture-proof cover. Background Technology

[0002] Cabinet door hinges typically consist of a hinge cup, a hinge base, and a connecting assembly between the two. They come in various types depending on the application, such as the high-strength novel hinge disclosed in patent number CN202021441706.9. During installation, the hinge cup and hinge base need to be installed onto the cabinet door panel and cabinet body panel respectively. Therefore, holes need to be drilled in both the cabinet door and cabinet body to install expansion joints, which are then secured with screws. This forces installers to find matching expansion joints, screws, hinge cups, and hinge bases during furniture installation. Furthermore, both the hinge cup and hinge base have at least two positioning holes; the repeated drilling and pre-embedding process is not only tedious, but the two positioning holes in the hinge cup are also prone to localized misalignment, requiring repeated adjustments and significantly impacting the furniture installation process. In addition, over long-term use, the hinge cup embedded in the panel is susceptible to moisture and corrosion. Therefore, further improvements are needed. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an integrated pre-embedded quick-install hinged moisture-proof cover.

[0024] Example

[0025] Reference Figures 1 to 3 This utility model proposes an integrated pre-embedded quick-install hinge moisture-proof cover, characterized in that it includes an integrally injection-molded cover body 20 and pre-embedded posts 30; the cover body 20 has a cap-shaped structure with one side opening, which can be fitted onto the outside of the cup head 10 of the hinge; there are two pre-embedded posts 30, located on opposite sides of the cover body 20, corresponding to the first positioning hole 11 of the cup head 10; the pre-embedded posts 30 are provided with a dividing groove 31 along the axial direction, and the dividing groove 31 divides the pre-embedded posts 30 into multiple annular expansion parts 32 that can expand with each other; the outer surface of the pre-embedded posts 30 is provided with an external tooth structure 33.

[0026] In this invention, a hinged moisture-proof cover comprising a capping body 20 and embedded columns 30 is integrally injection molded. The capping body 20 can wrap around the outside of the cup head 10 to achieve a moisture-proof effect. The two embedded columns can be pre-embedded into the cabinet door panel and are locked and fixed to the cup head 10 by the external chamfered structure 33 of the annular expansion part 32 and screws. In this invention, the capping body 20 and the embedded columns 30 are integrally injection molded, and the positioning dimensions of the two embedded columns 30 are accurate with minimal error displacement. This effectively reduces the time required for installers to find parts and make adjustments, speeding up the renovation process. Furthermore, the capping body 20, fitted onto the outside of the cup head 10, effectively prevents water from entering the cup head 10, achieving a moisture-proof and corrosion-proof effect.

[0027] In this embodiment, the capping body 20 includes a capping back plate 21, a circular outer wall 22, and a contour wall 23. The capping back plate 21 is circular, the circular outer wall 22 is arranged around the outer edge of the capping back plate 21, and the contour wall 23 is disposed on the inner side of the circular outer wall 22. The contour wall 23 and the capping back plate 21 enclose a main cap cavity 24, which can fit against the side wall of the cup head 10. The contour wall 23 and the circular outer wall 22 enclose a water-blocking cavity 25. The water-blocking cavity 25 is located outside the main cap cavity 24. Through the water-blocking cavity 25, a hollow water-blocking layer can be formed, further improving the water-blocking performance of the capping body 20.

[0028] Specifically, there are two main cover cavities 24, located near the two embedded columns 30, between the main cover cavity 24 and the embedded columns 30. Since water mainly seeps into the cabinet door through the screws and embedded columns 30, the space near the embedded columns 30 is prioritized for the arrangement of water-blocking cavities 25, which can be used to specifically treat the seepage points within the limited space.

[0029] In this embodiment, in order to make the expansion portion 32 expand and deform evenly, at least two dividing grooves 31 are evenly provided along the circumference.

[0030] Specifically, the external inverted tooth structure 33 includes multiple annular inverted ribs with inverted triangular cross sections.

[0031] Furthermore, at least six consecutive annular barbs are provided. These multiple inverted triangular annular barbs are compatible with standard sheet materials on the market, including thinner honeycomb aluminum panels, effectively gripping them and preventing loosening and detachment.

[0032] In this embodiment, in order to facilitate the screw alignment and locking of the embedded post 30, the embedded post 30 is provided with an inverted conical guide portion 34 at the end facing the cup head 10.

[0033] Furthermore, in order to improve the overall strength of the embedded column 30, several reinforcing ribs 35 extending axially are provided between the external tooth structure 33 and the guide part 34.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
