Description

Technical Field

[0001] The utility model relates to the technical field of door handles, in particular to a handle structure suitable for large doors. Background Art

[0002] Most existing large door handles (generally referring to bi-directional doors) use copper rings. While convenient for opening and closing the door, the rings tend to shake and make noise. Later, large doors adopted semi-circular handles, which leave a gap between the handle and the door for a finger to insert. While this gap is not visible from the front, it is noticeable from the side, necessitating further improvement. Utility Model Content

[0003] The purpose of the utility model is to provide a handle structure in which gaps are less visible compared with the prior art.
