Abstract
The present invention discloses a foldable strong magnetic force plate turning bed hinge which comprises a casing, a folding mechanism and a strong magnetic force mechanism, wherein the strong magnetic force mechanism comprises a sleeve, at least two strong magnets and a gear shifting device which is a turn buckle. A pressure mechanism of the present invention is a strong magnetic force mechanism matched with the turn buckle. When shifting, only by rotating and regulating a nut, can the distance between the strong magnets be regulated to obtain different strong magnetic repulsion forces. Because the turn buckle has no gear shifting with fixed quantity, the turn buckle can do clockwise or counterclockwise rotation to realize stepless regulation. The present invention is provided with a magnetic insulation cover (sleeve) to ensure that no magnetic force is discharged. The strong magnetic force mechanism basically has no mechanism loss and is not easy to be damaged, so that the service life of the foldable strong magnetic force plate turning bed hinge is largely extended.
