Description

Technical Field

[0001] The utility model relates to the technical field of door and window hinges, in particular to a hidden hinge structure. Background Art

[0002] Traditional hinged casement doors often leave the hinges exposed, leading to several issues. First, the exposed hinges are aesthetically pleasing, affecting the door's harmony with its surroundings and failing to meet the increasingly sophisticated aesthetic demands of modern consumers for interior design. Second, the exposed hinges not only make the door appear bulky but also increase the space occupied by the hinges, limiting the door's opening and closing freedom and hindering efficient space utilization.

[0003] Furthermore, the waterproof sealing strips of traditional swing doors are often exposed, a design flaw that compromises waterproofing. Exposed sealing strips easily accumulate dust and become damaged, compromising their waterproofing effectiveness. This allows rainwater and other liquids to seep between the door frame and the wall, potentially causing dampness and mold, impacting the comfort and safety of the living environment. This inadequate waterproofing not only increases maintenance costs but also potentially results in financial losses for users.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figures 1 to 7 As shown, the utility model relates to a hidden hinge structure, whose main components include a door frame 1, a door leaf frame 2 and a hinge assembly 3. The design of this structure aims to provide better hinge concealment and aesthetics, while improving the functionality and space utilization of the door body.

[0026] The door frame 1 has a first insertion slot 11 on its side, while the door leaf frame 2 has a second insertion slot 21 on its side. The hinge assembly 3 consists of a first base 31 and a second base 32. The first base 31 is concealed within the first insertion slot 11, while the second base 32 is concealed within the second insertion slot 21. These two bases are connected by a hinge structure, forming the hinge's pivot point. This optimizes the hinge's footprint and increases the door's freedom of opening and closing. This design allows the hinge assembly 3 to be concealed, making it less noticeable when the door is closed and enhancing the overall aesthetics.

[0027] The opposing end faces of the door frame 1 and the door leaf frame 2 are defined as a first end face 12 and a second end face 22, respectively. To enhance the door's sealing performance, a third recess 221 is provided on the second end face 22, into which a sealing strip 4 is embedded. Part of the sealing strip 4 protrudes from the third recess 221. When the door is closed, the first end face 12 and the second end face 22 abut and fit together, with the sealing strip 4 sandwiched between them, forming an effective seal. This design not only improves waterproofing but also simplifies the structure, further enhancing the overall aesthetics.

[0028] It is worth noting that, precisely because the hinge assembly 3 is hidden and installed in the first embedding groove 11 and the second embedding groove 21, the hinge assembly 3 does not occupy the space between the first end face 12 and the second end face 22, so that the first end face 12 and the second end face 22 can be smoothly fitted to form a waterproof sealing structure.

[0029] Preferably, the first end face 12 and the second end face 22 are designed to be compatible with each other. This design not only enhances the tightness of the door body when closed, but also helps to improve the overall visual smoothness, further enhancing the consumer's experience.

[0030] More specifically, the hinge assembly 3 is fixed by fasteners (such as screws), the first base 31 is fixed in the first embedding groove 11, and the second base 32 is also fixed in the second embedding groove 21 by fasteners.

[0031] More specifically, the hinged connection between the first base 31 and the second base 32 is as follows: A first axial hole 311 is provided on the first base 31, while an L-shaped arm 321 is provided on the second base 32, the free end of which is provided with a second axial hole 322. The first axial hole 311 and the second axial hole 322 are hingedly connected by a rotating shaft 33. This hinged design provides flexible opening and closing motion for the hinge, further enhancing the door's ease of use.

[0032] In order to further enhance the concealment of the hinge, a cover 34 is detachably connected to the outer end of the first base 31, and the outer side of the cover 34 is flush with the first end surface 12. This design not only effectively hides the existence of the hinge, but also makes the overall appearance more concise and beautiful.

[0033] In addition, the inner side surface of the first base 31 is provided with anti-slip grooves 312. The design of the anti-slip grooves increases the connection stability between the first base 31 and the first embedding groove 11, avoiding the hinge from loosening during use, thereby improving the safety and reliability of the door body.
