Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building decorative doors, in particular to a heavy-duty floor spring door. Background Art
[0002] Architectural decorative doors play an important role in architectural design and decoration. Architectural decorative doors include heavy-duty floor spring doors. Heavy-duty floor spring doors are hydraulic door closers suitable for various public places with large traffic, such as shopping malls, hotels, hospitals, airports, railway stations, etc. It can close automatically, reducing energy waste and facilitating people's passage. Heavy-duty floor spring doors belong to the field of architecture and decoration, especially in the architectural design of commercial and public facilities. It is not only a part of the building, but also a key element to achieve space separation, enhance the beauty of the building and achieve convenient access.
[0003] Common heavy-duty floor spring doors are usually composed of door leaves, floor springs, rotating shafts and bases, control systems, decorative panels and cover plates. When opening, the door leaf can be pushed open by the floor springs, rotating shafts and bases, and the floor springs will automatically buffer the opening speed and force of the door leaf. When closing, the door leaf will automatically return to its original position under the action of the floor springs and other structures. This is a common heavy-duty floor spring door structure and usage. Traditional heavy-duty floor spring doors cannot achieve uniform movement of the door leaf and cannot achieve the best door opening and closing effect. Some heavy-duty floor spring doors achieve uniform movement of the door leaf and achieve the best door opening and closing effect by adding encoders inside and connecting the corresponding structures. However, in this way, the encoder will increase the cost. At the same time, as a precision electronic device, it has high requirements for installation and maintenance, which increases the difficulty and cost of maintenance. In addition, the encoder is sensitive to environmental conditions, such as temperature, humidity and dust, which reduces the waterproof effect of the heavy-duty floor spring door. For this reason, a heavy-duty floor spring door is proposed. Utility Model Content
