The working principle of the embodiment is as follows:

folding the surrounding bed framework: as shown in fig. 9 and 10, after the locking mechanism of the chassis is unlocked, the upper base of the chassis is separated from the lower base by moving the upper base of the chassis upwards to drive the first bottom bar and the second bottom bar to rotate and fold, so that the upper ends of the first bottom bar and the second bottom bar move upwards, thereby linking the sliding member to move upwards along the upright posts and the plurality of upright posts move towards each other and towards the center of the chassis group, meanwhile, the driving section of the first bottom bar is driven by the upward movement of the upper base to pull the linkage group downwards, so that the linkage group loosens the support of the diagonal brace and the diagonal brace connecting seat, at the same time, the unlocking spring pulls the diagonal brace connecting seat or the unlocking member to move towards the direction far away from the upper enclosure connecting seat to separate the locking bolt, thereby automatically unlocking the upper enclosure locking mechanism, and enabling the two upper enclosures of each upper enclosure group to rotate downwards under the action of the plurality of upright posts moving towards each other and the diagonal brace, so that the upper enclosure frame is integrally folded to realize the integral folding of the enclosure bed framework.

Unfolding the surrounding bed framework: the upper base is pushed down to enable the upper base to be close to the lower base so as to drive the first bottom rod and the second bottom rod to rotate and expand to enable the upper ends of the first bottom rod and the second bottom rod to move downwards, so that the linkage sliding piece moves downwards along the stand columns and the plurality of stand columns move outwards in a radial mode relatively far away from each other, the drive section of the first bottom rod is driven by the downward movement of the upper base to push the linkage group downwards, the linkage group lifts the upper surrounding pipes upwards through the inclined supporting rods and the inclined supporting rod connecting seats, the two upper surrounding pipes of each upper surrounding pipe group are enabled to rotate and expand upwards under the action of the radial outwards movement of the plurality of stand columns relatively far away from each other so as to enable the upper surrounding frames to expand integrally, meanwhile, the linkage group applies acting force to the inclined supporting rod connecting seats through the inclined supporting rods so that the inclined supporting rod connecting seats drive the locking pieces and the locking bolts to move towards the direction close to the upper surrounding pipe connecting seats so as to enable the locking bolts to, therefore, the upper enclosure locking mechanism is automatically locked to enable the upper enclosure pipe group and the upper enclosure frame to be stably kept in the unfolding state, the integral unfolding of the enclosure bed framework is achieved, and finally the underframe locking mechanism is locked to ensure that the enclosure bed framework is in the stable unfolding state.

Example three: as shown in fig. 14, the difference between the present embodiment and the second embodiment is that the first bottom bar 321 includes two bottom frame links 3212 pivotally connected to each other, one bottom frame link 3212 is pivotally connected to the bottom base 311, and the other bottom frame link 3212 is connected to the lower end or lower corner base 22 of the corresponding upright 2.

The foregoing is illustrative of the various embodiments provided in connection with the detailed description and the specific implementations of the application are not intended to be limited to the illustrations. Similar or identical methods, structures, etc. as used herein, or several technical deductions or substitutions made on the premise of the idea of the present application, should be considered as the protection scope of the present application.
