Description
Technical field[0001]The invention relates to the field of casters, in particular to a resilient caster device, which is installed on a crib and can be quickly stowed or popped out, which overcomes the problem that the crib cannot be shaken in a fixed position in the prior art.Background technique[0002]Cribs refer to beds for infants and young children. The existing cribs are of various styles. Baby care beds are mainly temporary beds made of welded pipe materials and are used to temporarily place babies. Baby cribs often need to be moved, so casters are installed at the feet of the bed to facilitate the movement of the crib. When the baby is placed in the crib, it is often necessary to shake the crib to coax the baby to sleep.[0003]In the prior art crib, the crib frame is generally pivotally connected to the bed frame, and the crib frame is reciprocally oscillated by applying a shaking force to the crib frame to achieve a shaking effect. However, due to the presence of casters at t...
