Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a novel elevator swing door. Background Art

[0002] At present, the application of elevator swing doors is gradually becoming popular, and the structures of swing doors are also different. Due to the diversity of installation environments, swing doors need to be as convenient as possible to adjust on site. However, the existing elevator swing doors on the market generally have the problem that the door height cannot be adjusted on site.

[0003] There are two types of elevator swing doors on the market:

[0004] The first type: the elevator door frame and door leaf are directly assembled and adjusted in the factory. The door leaf cannot be removed during on-site installation, and the entire door system needs to be installed together. The disadvantage of this type of elevator swing door is that the door frame and door leaf are assembled together, which is heavy, inconvenient to carry and difficult to install. Secondly, since the door leaf cannot be removed for fine-tuning on-site, the installation accuracy is limited, affecting the normal operation of the elevator door.

[0005] The second type: the elevator door frame and door leaf can be installed separately, but the door leaf foot is directly placed on the sill, and the sill supports the weight of the entire door leaf. The disadvantage of this type of elevator swing door is that due to the on-site installation conditions, the door leaf height cannot be adjusted. A slight deviation in the door frame installation may cause the swing door leaf to scrape against the sill during operation, increasing the safety hazard of elevator operation; since the door leaf height cannot be adjusted on-site, once a problem occurs, the entire door system needs to be disassembled for adjustment, which increases the difficulty and cost of maintenance.

[0006] In summary, the elevator swing doors currently on the market have certain defects in design and installation, which not only increase the difficulty of installation and maintenance, but also may affect the safe operation of the elevator. Therefore, it is necessary to improve and optimize these problems to improve the applicability and reliability of elevator swing doors. Summary of the invention
