The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] Reference Figure 1 、 Figure 2 and Figure 5 According to the hinge of the embodiment of the first aspect of the present invention, it includes a first page body component 100, a connecting member 200, a second page body component 300, a first interlocking structure, a second interlocking structure, a first linkage structure and a second linkage structure. One end of the connecting member 200 is hinged to the first page body component 100, and the other end of the connecting member 200 is hinged to the second page body component 300. The first interlocking structure is arranged between the first page body component 100 and the connecting member 200. The first interlocking structure is used to limit the rotation of the connecting member 200 relative to the first page body component 100. The second interlocking structure is arranged between the second page body component 300 and the connecting member 200. The second interlocking structure is used to limit the rotation of the second page body component 300 relative to the connecting member 200. The first linkage structure includes a first linkage member 600. , the first linkage member 600 is provided on the connecting member 200, and can be moved axially along the hinge axis of the connecting member 200 and the first page body component 100 to connect or disconnect the second interlocking structure, and the second linkage structure includes a second linkage member 700, and the second linkage member 700 is provided on the connecting member 200, and can be moved axially along the hinge axis of the connecting member 200 and the second page body component 300 to connect or disconnect the first interlocking structure. In this way, when opening the T-type door, the second page body component 300 is rotated, and it can first rotate around the hinge between the first page body component 100 and the connecting member 200 to avoid the step of the door frame, and then rotate around the hinge between the connecting member 200 and the second page body component 300, thereby smoothly opening the T-type door and reducing the gap between the T-type door and the door frame.

[0049] Specifically, the first body assembly 100 is connected to the door frame, and the second body assembly 300 is connected to the T-type door. When the T-type door is closed, the first interlocking structure is disconnected and the second interlocking structure is connected, so that the second body assembly 300 cannot rotate relative to the connecting member 200, and the connecting member 200 can rotate around the hinge between the connecting member 200 and the first body assembly 100. When the T-type door is opened, the connecting member 200 and the second body assembly 300 rotate as a whole relative to the first body assembly 100 to avoid the step of the door frame. When the connecting member 200 continues to rotate, the first linkage member 600 drives the second interlocking structure to disconnect through the first linkage structure. At this time, the second page body component 300 can rotate around the hinge between the connecting member 200 and the second page body component 300, and the second linkage member 700 drives the first interlocking structure to connect through the second linkage structure to limit the rotation of the connecting member 200 relative to the first page body component 100. Then, the T-type door can be smoothly opened by rotating the T-type door. The T-type door does not interfere with the door frame, and the gap between the T-type door and the door frame can be reduced.

[0050] Reference Figure 1 、 Figure 6 and Figure 10 In some embodiments of the present invention, the first linkage structure also includes a first linkage groove 110 provided on the first page body component 100 and a first linkage part 610 provided on the first linkage member 600. The first linkage groove 110 includes a first groove section 111 and a second groove section 112 connected to the first groove section 111. The first groove section 111 and the second groove section 112 are arranged at an angle. The first linkage part 610 is movably accommodated in the first linkage groove 110. When the first linkage part 610 is located in the second groove section 112, the first linkage part 610 abuts against the side wall of the second groove section 112, which can facilitate driving the second interlocking structure to connect or disconnect.

[0051] Specifically, the first slot section 111 is arranged in the horizontal direction, and the second slot section 112 is arranged obliquely in the up-down direction. The angle between the first slot section 111 and the second slot section 112 is an obtuse angle. When the T-shaped door is opened, the first linkage part 610 first slides in the first slot section 111. When the first linkage part 610 slides to the connection between the first slot section 111 and the second slot section 112, the first linkage part 610 abuts against the side wall of the second slot section 112. The side wall of the second slot section 112 pushes the first linkage part 610 to move downward, thereby driving the second interlocking member 500 to move downward. The second interlocking member 500 moves away from the second page assembly 300, so that the second interlocking structure is disconnected.

[0052] When the T-shaped door is closed, the corresponding side wall of the second slot section 112 pushes the first linkage part 610 to move upward, thereby driving the second interlocking member 500 to move upward, and the second interlocking member 500 approaches the second page body assembly 300. The first linkage part 610 re-enters the first slot section 111, so that the second interlocking structure is connected, which can facilitate driving the second interlocking structure to connect or disconnect.

[0053] It should be noted that the positions of the first linkage groove 110 and the first linkage portion 610 can also be interchanged, that is, the first linkage groove 110 is provided in the first linkage member 600, and the first linkage portion 610 is provided in the first page body assembly 100, which is not limited here.

The second linkage groove 310 includes a third groove section 311 and a fourth groove section 312 connected to the third groove section 311. The third groove section 311 and the fourth groove section 312 are arranged at an angle. The second linkage part 710 is movably accommodated in the second linkage groove 310. When the second linkage part 710 is located in the fourth groove section 312, the second linkage part 710 abuts against the side wall of the fourth groove section 312, which can facilitate driving the first interlocking structure to connect or disconnect, and can facilitate driving the first interlocking structure to disconnect or connect.

[0055] When the second locking cam 710 is in the closed position, the locking cam 710 is in the closed position, and the locking cam 710 is in the closed position, so that the locking cam 710 is in the closed position.

[0056] When the T-shaped door is closed, the corresponding side wall of the fourth slot section 312 pushes the second linkage part 710 to move upward, thereby driving the first interlocking member 400 to move upward, the first interlocking member 400 approaches the first page body assembly 100, and the second linkage part 710 re-enters the third slot section 311, so that the first interlocking structure is connected.

[0057] It should be noted that the positions of the second linkage groove 310 and the second linkage portion 710 can also be interchanged, that is, the second linkage groove 310 is provided in the second linkage member 700, and the second linkage portion 710 is provided in the second page body assembly 300, which is not limited here.

[0058] Reference Figure 6 In some embodiments of the present invention, the first page body assembly 100 includes a first page body main body 101 and a first wear-resistant part 102. The first page body main body 101 and the first wear-resistant part 102 are detachably connected, and the first linkage groove 110 is provided on the first wear-resistant part 102. When the first wear-resistant part 102 is severely worn, the first wear-resistant part 102 can be replaced alone without replacing the first page body assembly 100 as a whole, which can reduce the maintenance cost of the hinge.

[0059] Specifically, the first wear-resistant part 102 is fixed to the first leaf body 101 by bolting, which makes it easy to replace the first wear-resistant part 102 without replacing the entire first leaf body assembly 100, thereby reducing the maintenance cost of the hinge.

[0060] In addition, by dividing the first body assembly 100 into the first body main body 101 and the first wear-resistant part 102, the structure of the first body assembly 100 can be simplified, and production can be facilitated.

[0061] It should be noted that the first wear-resistant part 102 can be made of wear-resistant material or chrome-plated steel, as long as it can improve the service life of the first page assembly 100, and there is no limitation here.
