Embodiment

[0034] The embodiment is described in conjunction with the implementation of the application and the accompanying drawings.

[0035] See figure 1 , a chassis folding device for a foldable crib, comprising a center seat composed of an upper joint 1 and a lower joint 2, one end of which is movably connected with the center seat in an X cross shape, and the other end is respectively movable with the four-corner vertical columns 91 of the crib The four connected chassis tubes 3. figure 2 for figure 1 local enlargement of image 3 yes figure 2 streamlining.

[0036] Figure 6 The push plate 4 shown has 2 narrow holes 41, and the soft ribbon 5 passing through the 2 narrow holes 41 (bypassing the beam between the 2 narrow holes) passes through the narrow hole in the middle of the top surface of the upper joint 1 in turn. After the hole 11, sew the soft ribbon 5 together, see image 3 shown.

[0037] Compared Figure 4 and figure 2 The upper joint 1 in the middle is visib...

Abstract

The invention provides a folding device for an underframe of a foldable children's bed. The folding device comprises a central base and two pairs of underframe pipes, wherein the central base comprises an upper joint, a lower joint, a push board, an interposer, a soft braid and other components, the two pairs of underframe pipes intersect in an X shape and are respectively connected with the upper joint and the lower joint in a movable manner, the interposer forms an adjusting structure for adjusting an angle between the two pairs of underframe pipes in conduction with the upper joint and the lower joint, the soft braid, the push board, a tenon, a spring and other components work together with the upper joint and the underframe pipe connected with the upper joint to form a control structure for unfolding locking and unlocking folding. The folding device has concise locking and unfolding modes, and when the underframe is locked, the angle between the two pairs of underframe pipes can be adjusted directly and no excess operation and misoperation space exists in the whole process.

Description

technical field [0001] The invention relates to the modification of a crib for infants and young children, that is, a bottom frame folding device for a foldable crib. Background technique [0002] Crib is an important baby product. There is sufficient space for babies to play or play games in the crib, or to sleep and rest, and the safety of babies can be fully guaranteed. Cribs reduce the burden and bring convenience to parents in raising children. [0003] In order to reduce space occupation and facilitate transportation and movement, folding when not in use is an essential function of general cribs at present. In the foldable crib, the basic mode of the base frame is that one end of the four base frame tubes is respectively connected to the vertical tubes at the four corners of the crib, and the other ends are movably connected to the center seat respectively. When the crib is in use, the four underframe tubes intersect horizontally in an X shape, and the four underfra...
