[0026] As shown, the hinge 3 is located on the side of the first connection frame body 1, and the second connection frame body 2 is connected to the other side of the hinge 3, the hinge 3 is connected by a first leaf plate 31 and the first connection frame body 1, and a second leaf plate 32 and the second connection frame body 2, in the structure, the hinge 3 is the simplest bolt fixed connection;

[0027] As shown, the extension 4 extends to the side of the first connection frame body 1 on the inner side of the second connection frame body 2, the extension 4 is opposite to the end face of the first connection frame body 1, the extension 4 includes a first extension 41 and a second extension 42, the extension 4 on the back is the second extension 42, and the first extension 41 and the second extension 42 in the figure are mirror image design, so that the inner side of the second connection frame body 2 forms a wrapping cavity 100 wrapping the first connection frame body 1, in the embodiment, the extension 4 is parallel to the front end of the first connection frame body 1, and because the connecting surface of the first connection frame body 1 is rectangular, the side wall surface of the first connection frame body 1 is perpendicular to the axis of the extension 4, when the door leaf is in the closed state, the extension 4 covers the end face of the first connection frame body 1, and the extension 4 covers the end face of the column as the pivot point of the door leaf, so that the whole door body is more beautiful in appearance;

[0028] As shown, the second connection frame body 2 is an integral molding profile, and is rectangular, the extension 4 is extended from the frame cutting surface of the second connection frame body 2, and the structure has a mounting groove 200, the mounting groove 200 is located on the back side away from the extension 4, and can be understood as mounting glass and other media, specifically glass door body structure, so that the mounting groove 200 has a partial structure matched with the glass installation, which will not be described here, the foregoing can be applied to the single door side, and simply understood as follows, when the first connection frame body 1 is located in the door pocket structure formed by a plurality of door holes, or applied to a plurality of double doors, the two sides of the first connection frame body 1 are connected to the second connection frame body 2 through the hinge 3;

[0029] When two sets of opposite second connecting frame 2 are spliced together, the covering of the first connecting frame 1 or the integrity of the door pocket is ensured, and there is no gap or gap between the door and the door, and the effective resistance between the second connecting frame 2 is ensured, and the buffer 5 is provided on the extension 4, which is hollow and bullet-shaped. When the two doors are closed, the two opposite buffers 5 are pressed against each other, forming a seal. The buffer 5 is connected with the groove of the first extension 41, and the buffer 5 has an end that fits the groove;

[0030] It should be noted that, as shown in the figure, the buffer 5 of the first extension 41 and the second extension 42 are similar in structure, even the limiting sealing member 300 is the same, and their main functions are sealing, buffering and limiting. Therefore, it will not be described here;

[0031] In the improvement of the above structure, when the second connecting frame 2 is in an open state, specifically by rotating the second connecting frame 2 by the hinge 3, the hinge 3 is slowly opened, the second connecting frame 2 penetrates the gap between the two hinges, and finally the axis is perpendicular to the second connecting frame 2. The limiting portion 6 of the limiting portion 6 in the first connecting frame 1, the limiting portion 6 is a convex arc surface, one side of the arc surface is a flat surface connected perpendicularly to the arc surface, and the flat surface and the arc surface form an angle 400. The hollow buffer 5 is in contact with the top end of the arc surface and is pushed by an external force, so that the buffer 5 is pressed to the angle 400 along the slope, and the limiting portion 6 has a resistance effect on the second connecting frame 2 through the buffer 5;

[0032] It should be noted that the foregoing only proposes a design of a set of extensions 4 covering the front and rear end faces of the first connecting frame 1, and the extension 4 is only a symmetrical structure. It can be simply understood that the extension 4 can also be designed as a single set of design covering only the front end of the first connecting frame 1;

[0033] The hinge 3 is a hidden hinge 3, and the first page plate 31 has a hollow groove. The second page plate 32 is located in the hollow groove and is connected with the first page plate 31 by the connecting shaft portion on the first page plate 31. The two page plates are in the same direction, and the hinge 3 is located between the first connecting frame 1 and the second connecting frame 2, and the first connecting frame 1 and the second connecting frame 2 have a hollow layer 500. Therefore, the limiting sealing member 300 is located on one side of the hinge 3, and the shaft core of the hinge 3 is located at the transition of the second extension 42 and the second connecting frame 2. Therefore, the opening state of the second connecting frame 2 is matched with the above;

[0034] It should be noted that the first connecting frame 1 and the second connecting frame 2 have a convex edge for limiting the installation of the hinge 3;

[0035] It should be noted that the first extension 41 and the first connecting frame 1 have an extension hollow layer 600, and the first page plate 31 and the second page plate 32 can move reversely, that is, the extension hollow layer 600 can provide a reserved space when the door leaf is reversely opened, and is pressed by the buffer 5, and the hollow layer 600 and the hollow layer 500 are the moving space of the first connecting frame and the second connecting frame.

[0036] It should be noted that the back of the first connecting frame extends an extension, which gives the hinge more moving space.

[0037] As shown in Figures 4-5 The second application of the second connecting frame 2 is a split type second connecting frame 2, which includes two mirror-symmetrical L-shaped main profiles 201 matched together, and also forms a second connecting frame 2 with a mounting groove 200 by splicing assembly 202, and the extension 4 is also integrally formed with the second connecting frame 2, so that the extension 4 is also integrally combined with the main profile 201 to form the same application as in case one.

[0038] In case two, the first connecting frame 1 is also provided with an auxiliary groove 101, which is located on the side wall of the first connecting frame 1 and can also install a buffer.

[0039] When the second connecting frame wraps the first connecting frame through the extension, it is in the closed state of the door leaf, and the hinge is located on the side of the first connecting frame, and the shaft core of the hinge is clamped at the transition between the side and the back of the first connecting frame, so that the second connecting frame rotates inward from the rear end of the first connecting frame as a fixed shaft, and the first extension slowly rotates to expose the front of the first connecting frame, and the second extension slowly travels to the gap between the two hinges, and then travels from the angle direction after pressing the top end of the limiting part, and completes the opening of the door leaf, and the limiting part limits the second extension.
