Technical solution of the present invention: the head end base of Children’s bed and bed end base are respectively for can implement the horizontal sissy bar that Children’s bed rocks, a rocking horse transformed structure is installed in junction at each Children’s bed footpost and sissy bar end, every rocking horse transformed structure contains a universal wheel, it is characterized in that: it also comprises pedestal, cavity spare, compressing spring, pin, and with the integrated footstalk of pin axle of universal wheel, wherein:

1) pedestal is fixed in the junction of footpost and sissy bar end, there is pulling-on piece cavity spare lower end, footstalk inserts in the cavity spare, compressing spring in cavity spare, push up and footstalk upper end between, pin crosses pedestal side circular hole, the vertical slotted hole in cavity spare side, footstalk top circular hole, and universal wheel and pedestal are riveted indirectly;

2) the pulling-on piece upper bottom surface has rib, and the pedestal side of pin below has the ∩ shape groove that is matched with rib, and the outer end of pedestal side is arc-shaped side, and the upper end of arc is re-entrant angle.

All there is rib both sides before and after the pulling-on piece, and all there is arc-shaped side the outer end of pedestal front and back sides, and the pedestal front and back sides all has ∩ shape groove and the re-entrant angle that matches.

The occupation mode of the present invention's structure: the rib on pulling-on piece is positioned at ∩ shape groove, compressing spring in the cavity spare between on top and the footstalk is not compressed or only contracted by minute-pressure, the tension force of compressing spring is naturally offed normal the top, upper end of cavity spare and is put fixing horizontal pin at this moment, be that rib is positioned at the in stable condition of ∩ shape groove, be suitable for the Children’s bed walking this moment, and universal wheel makes Children’s bed mobile arbitrarily with user's wish, but the spanner of universal wheel can lock Children’s bed is not moved; As pressing down manually pulling-on piece (with spring-compressed), make rib deviate from ∩ shape groove, and the association of rotating cavity spare, footstalk and universal wheel along the arc-shaped side of outer end, pedestal side, until rib removes manual external force when being positioned at the re-entrant angle of arc upper end, then the outer bullet tension force of compressing spring is again offed normal the upper top of cavity spare and is put fixing horizontal pin, namely this moment, universal wheel was positioned at the in stable condition and self-sustaining of being lifted to sissy bar top, do not affect rocking of Children’s bed, but like this then finished Children’s bed from walking states to the conversion that can rock state.Press the contrary of said process, but Children’s bed will be finished from rocking state to the conversion of walking states.

In this rocking horse transformed structure, because pin makes cavity spare, footstalk be connected to pedestal, and the cooperating successively of the existence of compressing spring and rib and ∩ shape groove, re-entrant angle, Children’s bed removable and can to rock two kinds of running statuses all fully reliable and stable, eliminated Children’s bed before this can rock and removable between misroute and change; Universal caster axle and the integrated of footstalk and simply compact, easy to use with cooperating of cavity spare, compressing spring.
