Description

A limit opening and closing mechanism for furniture rotary sliding doors

technical field

The invention relates to a limit opening and closing mechanism for a furniture rotary sliding door.

Background technique

Chinese Patent Document No. CN2327260 on July 7, 1999 discloses a full-length mirror with a hidden storage cabinet, which has a cabinet room, the rear wall and the side walls of the cabinet room form a space and a front opening, and an inlaid The mirror cabinet door is fixed on the cabinet room with hidden hinges, and can cover the front opening of the cabinet room, thus forming a mirror-inlaid storage cabinet. The mirror storage cabinet is installed between two pillars on a support, and is rotatably fixed on the pillars so that the storage cabinet can be tilted. There is a tilt adjustment mechanism at the distance from the rotation point, which can adjust the relative position of the mirror storage cabinet. It depends on the tilt angle of the support column and keeps it in different angular positions. However, the storage space in the cabinet of this structure is limited and cannot be widely used in large furniture cabinets. If the full-length mirror is designed to be larger, it will take up space, and the full-length mirror cannot be pushed into storage or pulled out to achieve the positioning effect. , The full-length mirror is prone to the problem of swinging left and right due to hinge rebound or the original car itself, which can easily cause safety hazards such as damage to the full-length mirror or injury to the user during use, which cannot meet the needs of the user. Therefore, further improvement is necessary.
