Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of length adjusting devices, in particular to a length adjusting device for an iron bed. Background Art
[0002] Steel beds often require some degree of length adjustment to accommodate varying user needs or space constraints. This can be achieved through the use of retractable support structures, slide rail systems, or adjustable connectors. These devices can be manually operated or designed for automatic motorized or mechanical adjustment, providing a more convenient user experience.
[0003] Common iron bed bodies are generally supported by a fixed frame, and the bed plate can slide back and forth along fixed tracks or slide rails through a sliding frame, and the sliding frame is pushed by a driving machine to move along the fixed frame.
[0004] In order to facilitate the adjustment of the length of the bed, generally only the crossbeams of the bed are connected, and the two crossbeams are plugged into each other. The length of the bed can be adjusted by moving the crossbeams. However, since the crossbeams will also drive the support plates to move after moving, and the support plates of the crossbeams are of the same height, the support plates are used to support the upper surface of the bed and bear the weight of the human body. They will be evenly distributed between the crossbeams, resulting in the support plates squeezing each other when adjusting the length of the bed, and the movement of the crossbeams is hindered.
