[0002] A swing door is a unique door structure that can swing around a fixed point and can usually be opened in both directions, inward and outward. This two-way opening feature makes the swing door more flexible than traditional doors that can only be opened in one direction. Due to its convenient use, swing doors have been widely used in many specific occasions. For example, in public places, commercial buildings, hospitals, factories and other places with large traffic, swing doors can effectively avoid crowd congestion and improve traffic efficiency.

[0003] Some swing doors in the prior art lack an anti-pinch structure, which increases the risk of pinching accidents, especially for children and the elderly. Secondly, the lack of an anti-pinch structure may make the door unsafe to use, and users need to be particularly careful when closing the door to avoid pinching. Finally, pinching accidents may cause personal injury, trigger legal liability and compensation issues, and bring unnecessary legal risks and economic burdens to building managers and owners. Summary of the invention

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A new swing door structure includes an installation door frame 1, a swing door 2, and a secondary door 3. The installation door frame 1 is rotatably connected to the swing door 2 on one side, and the installation door frame 1 is rotatably connected to the secondary door 3 on the side away from the swing door 2. Both side surfaces of the secondary door 3 are arranged to be arc-shaped surfaces to prevent the rotation of the secondary door 3 from being limited.

[0021] An installation box 7 is fixedly provided on one side of the installation door frame 1 near the secondary door 3, an edge block 4 is fixedly provided on the front side of the installation box 7 by bolts, a front guard door 5 is fixedly provided on the other end of the edge block 4, an anti-pinch assembly is provided in the inner cavity of the installation box 7 to prevent the swing door 2 from pinching the hand, the anti-pinch assembly includes a common plate 11, a brittle plastic column 8, a fixed copper ring 9 and a reset adjustment assembly for resetting the secondary door 3, fixed copper rings 9 are fixedly provided on the common plate 11 at equal intervals along the vertical direction, the fixed copper ring 9 has a brittle plastic column 8 movably inserted therein, and installation bolts 10 are screwed into the side threads of the fixed copper ring 9.

[0022] The tail end of the mounting bolt 10 contacts the outer wall of the brittle plastic column 8, and a limiting hole 31 is provided on the side of the secondary door 3 in the vertical direction. The other end of the brittle plastic column 8 is movably inserted into the limiting hole 31. The reset adjustment assembly includes an intermediate screw 12 and a fixing nut 13. Both ends of the intermediate screw 12 are rotatably connected to the side of the mounting box 7. The intermediate screw 12 is threaded into the common plate 11. A fixing nut 13 is fixedly provided at one end of the intermediate screw 12. A circular array of rotating holes 14 is provided on the outer side of the fixing nut 13. An operating port 6 is provided in the middle position of the front guard door 5. The operating port 6 is located on the front side of the fixing nut 13, thereby allowing the user to use a wrench or an iron rod to rotate the fixing nut 13 to drive the intermediate screw 12 to rotate.

[0023] The specific implementation steps and principles of the utility model are as follows:

[0024] When the entire swing door structure is working normally, the two groups of brittle plastic columns 8 are inserted into the limiting holes 31, and the secondary door 3 cannot swing at this time. When the user accidentally extends his hand between the secondary door 3 and the swing door 2 when opening the swing door 2, the user's hand is forced to apply pressure to the secondary door 3, and the brittle plastic column 8 in the anti-pinch hand assembly will automatically break, and the secondary door 3 can rotate freely again.

[0025] When the secondary door 3 needs to be reset, the fixing nut 13 is rotated by a wrench through the operating port 6 , and the fixing nut 13 drives the two groups of brittle plastic columns 8 to be inserted into the limiting hole 31 again through the intermediate screw 12 .

[0026] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
