[0061] The above-mentioned structure adopts a door connector 300 that is detachably arranged with the rotating arm 200 to adapt to different door types. Different door types can be adapted by producing door connectors 300 with different structures, thereby avoiding the replacement of the entire hinge. The adaptation cost is low, and the hinge part except the door connector 300 can adopt a universal structure, thereby facilitating production and manufacturing; the door connector 300 adopts the structure of a base plate 310 and an adapter plate 320. Through the production adjustment of the position of the adapter plate 320 relative to the base plate 310, and the use of different base plate 310 structures, the adaptation to different door types can be achieved with a simple structure. The adaptation structure is simple and easy to implement in production.

[0062] In the embodiment, the adapter plate 320 is provided with a left-right adjustment strip hole 510, and the other end of the rotating arm 200 is provided with a first fixing screw hole 520, the left-right adjustment strip hole 510 is extended in a direction perpendicular to the plate surface of the base plate 310, the first fixing screw hole 520 is opposite to the left-right adjustment strip hole 510, and the left-right adjustment strip hole 510 is penetrated by a first screw 530, the first screw 530 is threadedly connected with the first fixing screw hole 520 and is used to lock the adapter plate 320 and the other end of the rotating arm 200 together. With the above structure, on the one hand, the adapter plate 320 and the other end of the rotating arm 200 can be disassembled by removing the first screw 530, and on the other hand, by setting the left-right adjustment strip hole 510, the relative position of the rotating arm 200 and the adapter plate 320 can be adjusted when the first screw 530 is loosened, so as to achieve the left-right position adjustment of the door 900 relative to the door frame 800. In some embodiments, the left and right adjustment bar holes 510 may also be disposed at the other end of the rotating arm 200 , and the first fixing screw hole 520 may be correspondingly disposed on the adapter plate 320 .

[0063] In the embodiment, there are multiple groups of left and right adjustment holes 510, first fixing screw holes 520 and first screws 530 and they are arranged in a row along a straight line. With multiple groups of left and right adjustment holes 510, first fixing screw holes 520 and first screws 530, the fixing between the rotating arm 200 and the adapter plate 320 is more stable.

When the push screw is rotated, the push block can be driven to move along the axis direction of the vertical hollow hole. The push block pushes the bayonet pin through the push inclined surface, so that the bayonet pin extends out and plugs into the corresponding bayonet pin hole, thereby realizing the connection between the adapter plate 320 and the other end of the rotating arm 200; when the push screw is reset, the push block is reset, and the two bayonet pins can be reset by the spring, and the bayonet pin withdraws from the bayonet pin hole, so that the adapter plate 320 and the other end of the rotating arm 200 can be disassembled. With the above structure, when connecting the adapter plate 320 and the other end of the rotating arm 200, the connection can be formed first by the cooperation of the card block and the card slot, and then the two bayonet pins are driven to extend and insert into the bayonet pin hole by rotating the push screw, thereby realizing the connection. The card connection is formed by two bayonet pins, and the connection is relatively stable. In addition, the above structure can complete the connection by operating a single screw, and the assembly is also relatively convenient.
