Background

In order to fully utilize the space below the bed body to store articles and expand the use function of the bed, the bed frame or the bed board is required to realize the functions of lifting and falling. The lifting bed frames produced in the current market are mainly divided into two types, namely electric lifting bed frames and bed frames lifted by elastic lifters. The electric lifting bedstead mainly lifts up the bedstead or the bed board of the bed by opening the electric lifter, and has the disadvantages that the electric lifter needs a power supply to support, and in the lifting process, if the condition of power failure occurs, the bedstead or the bed board can stay at a certain position in the space and cannot be restored, and in addition, the manufacturing cost of the electric lifting bedstead is higher. Therefore, more and more manufacturers adopt the elastic lifter as a power source for lifting the bed frame, but the following disadvantages still exist:
