[0035] Further, as a preferred embodiment of the present scheme but not limited, the door body hinge assembly 4 comprises a door body front connecting member 41 arranged on the front side of the door body 3, a door body back connecting member 42 arranged on the back side of the door body 3, the door body front connecting member 41 is provided with a second hole column 411 for penetrating the door body 3, the door body back connecting member 42 is provided with a second through hole 421 corresponding to the second hole column 411, and a fastener penetrates the second through hole 421, the door body 3 and the second hole column 411 to install the door body hinge assembly 4 on the door frame 1.
[0036] In the embodiment, the second hole column 411 on the door body front connecting member 41 corresponds to the second through hole 421 on the door body back connecting member 42, which allows the fastener to directly penetrate the door body 3, and the door body hinge assembly 4 is firmly installed on the door frame 1, and the structure not only simplifies the installation process, reduces the time and tools required for installation, but also effectively prevents the door body hinge assembly 4 from loosening and shifting during use through the pre-tightening force of the fastener, ensuring the smoothness and stability of the door body opening and closing.
[0037] Further, as a preferred embodiment of the present scheme but not limited, the door frame front connecting member 21 is provided with a first connecting hole 212, the extension piece 52 is provided with a second connecting hole 5211 corresponding to the first connecting hole 212, and a fastener penetrates the first connecting hole 212 and the second connecting hole 5211 to connect the extension piece 52 with the door frame front connecting member 21.
[0038] In this embodiment, the secure assembly between the extension piece 52 and the door frame front connecting member 21 is achieved through the connection of the fastener. This design not only improves the overall structural strength and durability of the hinge, but also provides great convenience for installation and maintenance. The fastener passes through the first connecting hole 212 and the second connecting hole 5211, which not only provides sufficient pre-tightening force to prevent the extension piece 52 from loosening or shifting during use, but also simplifies the installation steps, reduces the installation time and tool requirements.

[0040] In this embodiment, the offset or jamming of the shaft 51 during use is avoided. At the same time, the installation site 224 formed between the first positioning hole 222 and the second positioning hole 223 provides an accurate installation space for the bearing part 522 of the extension piece 52.
[0041] Further, as a preferred embodiment of the present scheme but not limited, it further includes a door frame protection cover 8 sleeved outside the door frame hinge assembly 2, a door body protection cover 9 sleeved outside the door body hinge assembly 4, and a clamping mechanism 10 for positioning the door frame hinge assembly 2 and the door body hinge assembly 4 with the door frame protection cover 8 and the door body protection cover 9 respectively.
[0042] Further, as a preferred embodiment of the present scheme but not limited, the clamping mechanism 10 includes a recess hole 101 arranged on the door frame hinge assembly 2 and the door body hinge assembly 4, an elastic member 102 and a clamping member 103 arranged in the recess hole 101, and a clamping groove 104 arranged on the inner wall of the door frame protection cover 8 and the door body protection cover 9 and for the clamping member 103 to be clamped into.
[0043] In this embodiment, the clamping mechanism 10 is used to realize the positioning of both, which not only provides comprehensive protection for the hinge structure, but also improves the simplicity and aesthetics of the overall appearance. The door frame protection cover 8 and the door body protection cover 9 can effectively prevent dust, water stains and other external factors from eroding the hinge assembly, prolong the service life of the hinge, and ensure the smoothness of the door opening and closing. The design of the clamping mechanism 10 simplifies the installation and removal process of the protection cover, allowing it to be quickly and securely fixed on the hinge assembly, while avoiding the use of additional fasteners, making the appearance more neat.
[0044] Further, as a preferred embodiment of the present application but not limited, the inner wall edge of the door frame protection cover 8 and the door body protection cover 9 is provided with a bevel chamfer 81.
[0045] In this embodiment, not only the convenience of assembly between the protection cover and the hinge assembly is improved, but also the wear and tear that may occur during assembly is significantly reduced. The bevel chamfer 81 provides a smooth transition area by eliminating the sharp part of the edge of the protection cover, so that the protection cover can be more easily slid into and fixed on the hinge assembly, thereby simplifying the installation steps and speeding up the assembly. The bevel chamfer 81 also helps to disperse the stress during assembly, avoiding damage to the protection cover or the hinge assembly due to stress concentration on the edge, and prolonging the service life of the entire hinge structure.

[0047] In this embodiment, not only the connection tightness between the protection covers is optimized, but also the overall appearance of the hinge is improved in smoothness and aesthetics. This structure forms a smooth and continuous transition area through the mutual fitting of the arc surface 82 and the curved surface 92, eliminating the visual abruptness at the connection of the protection covers, so that the hinge presents a more harmonious and unified appearance in the closed state.
[0048] The working principle of this embodiment is as follows:
[0049] The hinge structure of the present application effectively avoids the exposure of the rotating shaft by setting the rotating shaft in the door body hinge assembly or the door frame hinge assembly and connecting it with the other assembly by the extension piece. This design not only prevents water splashes from splashing on the rotating shaft, avoids the accumulation of water stains and dirt, thereby improving the smoothness and durability of the hinge, but also makes the overall appearance more simple and beautiful, improves the aesthetics and integrity of modern home design, and is particularly suitable for use in humid environments such as bathrooms, thereby prolonging the service life of the door.
