The working principle of the above-mentioned bed frame structure 100 will be described in detail below in conjunction with FIGS. Use as a crib.

When the bed frame structure 100 needs to be used as a bedside bed, the bed frame structure 100 is brought closer to the adult bed, and the telescopic part 52 is in contact with the adult bed, and the telescopic part 52 will overcome the elastic force of the reset part 59 to the main body part 351 under external force. The retraction drives the locking part 355 to slide towards the fixing part 57 . Under the guidance of the sliding member 571 and the sliding part 551 , the telescopic part 52 shrinks inside the main body part 351 and is in a contracted state, so that the distance between the bed frame structure 100 and the adult bed is closer.

When the bed frame structure 100 is not needed, the bed frame structure 100 can be folded. Operate the supporting leg 5 to fold toward the bed body 10 to be in the folded state, the first part 315 presses the driving pin 73, and the driving pin 73 drives the driving part body 71 to overcome the elastic force of the restoring part 90 to move toward the fixed part 57, and then operate the telescopic The telescoping part 52 shrinks, and drives the positioning part 553 on the locking part 355 to approach the fixing part 57 until the engaging part 3711 engages with the positioning part 553, and the telescopic part 52 is locked in a contracted state.

When the bed frame structure 100 needs to be unfolded, the operating support legs 5 are in the unfolded state, and the first portion 315 will not exert pressure on the driving portion 70 . Under the action of the restoring member 90 , the driving part 70 is extended, and drives the engaging member 3711 and the positioning member 553 to be unlocked. At the same time, under the action of the reset portion 59 , the telescoping portion 52 is in an extended state away from the fixing portion 57 . Assemble the connecting piece 313 and the supporting foot 5, so that the bed frame structure 100 can be used normally.

Compared with the prior art, when the above-mentioned bed frame structure 100 is not in use, the telescopic part 52 is contracted relative to the main body part 351 to be in a contracted state, and at the same time, the supporting legs 5 are folded relative to the bed body 10 , so that the supporting legs 5 are in the folded state, thereby restricting the transition of the telescopic part 52 from the contracted state to the extended state, effectively reducing its occupied space, and facilitating storage and transportation. And when the support leg 5 is in the extended state, the telescopic part 52 is converted from the contracted state to the extended state, which is convenient to use.
