Referring to fig. 6 in combination with fig. 4 and fig. 5, the upper hinge 13 and the lower hinge 14 are provided with fixing holes 15, and the upper hinge 13 and the lower hinge 14 are connected with one end of the door frame 11 opposite to the door leaf 12 by means of screws 16 through the fixing holes 15, so that the screws 16 are not exposed after the invisible door 1 is completely installed, and the hinges are further hidden. Specifically, the fixing holes 15 are formed at the upper connecting surface 131 and the upper mounting surface 132 of the upper hinge 13, so as to connect and fix two ends of the corner of the door frame 11, and the strength of the door frame is enhanced while the upper hinge 13 is fixed. The lower hinge 14 has only a lower connecting surface 141 provided with a fixing hole 15, and since the lower hinge 14 needs to support most of the weight of the door leaf 12, the lower connecting surface 141 can be properly extended, and three or more fixing holes 15 are provided to ensure strength.

Preferably, as shown in fig. 5, the lower mounting surface 142 is provided with a cambered surface structure 1421 so that the second connecting shaft 143 and the first connecting shaft 134 are coaxially arranged, the lower connecting surface 141 does not need to be arranged in an offset center for correspondingly arranging the second connecting shaft 143, the connection strength of the lower hinge 14 is further improved, and the area of the lower mounting surface 142 can be reduced by arranging the cambered surface structure 1421, so that the lower hinge 14 can be hidden maximally.

As shown in fig. 6, the screw 16 may directly penetrate into and fix the end of the door frame 11 opposite to the door leaf 12, or may penetrate into and fix the end opposite to the door leaf 12 and then shield by the baffle 113, and in any fixing mode, the screw 16 is connected with the end of the door frame 11 opposite to the door leaf 12, so as to ensure that the exposed end surface of the door frame 11 is neat and beautiful.

In addition, as shown in fig. 7 and 8, the door leaf 12 provided by the embodiment of the invention includes a keel 121 and panels separately arranged at two sides of the keel 121, and the keel 121 is formed by splicing profiles through corner joints. In particular, the profile comprises two vertical profiles 1211 and a transverse profile 1212 for connecting the vertical profiles 1211.

Further, as shown in fig. 8, the corner brace is a U-shaped corner brace 122, each connection port of the transverse profile 1212 and the vertical profile 1211 is provided with the U-shaped corner brace 122, and the U-shaped corner brace 122 is fixedly arranged in the transverse profile 1212 and connected with the vertical profile 1211.

In other manners, the splicing manner of the keel 121 is not specifically limited, for example, more than three vertical profiles 1211 may be provided, only two upper and lower transverse profiles 1212 may be provided, even the profiles may be obliquely arranged to form a stable triangular structure, and the specific splicing structure of the keel 121 may be set according to the type, size, use, etc. of the door leaf.

In this embodiment, the specific assembling method of the keel 121 includes fixing the U-shaped corner connector 122 on the vertical section 1211 by using a screw 16, sleeving the end opening of the transverse section 1212 on the U-shaped corner connector 122, and fixing the U-shaped corner connector 122 in the transverse section 1212 by using the screw 16. It should be understood that, before installation, through holes or threaded holes for adapting the screws 16 are correspondingly provided in the vertical profile 1211, the transverse profile 1212 and the U-shaped corner bracket 122.

Preferably, the profile is made of an aluminum alloy material, and the joist 121 formed by splicing the profile reduces the weight of the door leaf 12 under the condition of ensuring that the door leaf 12 has enough strength, is less susceptible to environmental factors than a wood joist structure of a conventional door leaf, such as deformation, warping and the like of the door leaf caused by room temperature change, and can reduce the use of wood, thereby being more environment-friendly and energy-saving. In addition, the processing procedure of the keel 121 can be reduced through the splicing of the sectional materials, for example, the shaft holes for sleeving the first connecting shaft 134 and the second connecting shaft 143 can be directly formed integrally during the processing of the sectional materials, and the installation and the adjustment are simpler and more convenient.
