Description

Technical Field

[0001] This utility model relates to the field of bedside handrail technology, and in particular to a liftable bedside handrail. Background Technology

[0002] Bedside handrails are assistive devices that are usually installed beside the bed to help users get up, lie down, or turn over more easily. They are especially suitable for the elderly, the frail, or people with limited mobility.

[0003] Existing bedside armrests have fixed structures, which means users need to remove them when getting out of bed or create space when installing them, causing inconvenience. To eliminate the obstruction caused by the armrests, existing bedside armrests generally use folding or flip-up designs. However, in practice, folding designs are prone to causing the armrests to collide with the armrest supports or the bed frame, resulting in damage to both and reducing the lifespan of the armrests. Folding designs, even when folded, still result in a height higher than most mattresses, making it inconvenient for users to get out of bed. Utility Model Content

The locking assembly 6 is provided with a sleeve 61, and a slider 62 is slidably disposed inside the sleeve 61. A groove 621 is formed on the slider 62, and a slot 622 is provided on the side wall of the slider 62. The slot 622 is used to fix the end of the connector 54. The connector 54 drives the slider 62 to move. A locking block 63 is fitted on the slider 62 at the position of the groove 621. A second spring 64 is connected to the side of the locking block 63 near the groove 621. When the connector drives the slider 62 to move upward, the slider 62 moves backward and squeezes the second spring 64. A lock head is connected to the side of the locking block 63 away from the groove 621, so that the lock head disengages from the docking hole 121, so that the handrail 2 is in the unlocked state. The lock head is adapted to the docking hole 121. When the handrail is fixed, the lock head is engaged in the docking hole 121.
