Description

Technical Field

[0001] The invention relates to the field of children's products, in particular to a diaper changing table with a smaller storage space after being folded. Background Art

[0002] A diaper changing table is a piece of furniture specially used for changing diapers for babies. Its main feature is that the height is suitable for adults to stand and operate, and the height can also prevent the baby from rolling off the table to ensure the baby's safety. Diaper changing tables are usually equipped with fences and safety belts. The fence can prevent the baby from accidentally rolling off the table, and the safety belt can fix the baby on the table to increase the safety of diaper changing. In addition, diaper changing tables are often designed with storage space, such as lockers, drawers or partitions, etc., which are convenient for parents to store diapers, wet wipes, spare clothes and other baby supplies, improving the efficiency and convenience of diaper changing.

[0003] The existing diaper changing table includes two U-shaped rods hinged to each other in an "X" shape, and a foldable support frame is hinged between the upper parts of the two U-shaped rods. When the diaper changing table is not in use, the two U-shaped rods and the support frame can be folded to reduce the space occupied by the diaper changing table, but the height of the diaper changing table after folding is higher than the height when in use, which makes the diaper changing table still large in size when packed and stored.

[0034] Reference Figure 1 The bottom of the left support rod 6 and the bottom of the right support rod 7 are both provided with rollers 23, and the rollers 23 facilitate the movement of the diaper changing table.

[0035] Reference Figures 1 to 10 The design principle of the present invention is as follows: when the diaper changing table needs to be folded when not in use, the buttons 18 on the two left rotating members 15 are pressed, and the pressing portion 181 on the button 18 pushes the engaging member 17 to move inward, so that the multiple engaging grooves 171 of the engaging member 17 are disengaged from the multiple first engaging portions 151 of the left rotating member 15, and only engage with the multiple second engaging portions 161 of the right rotating member 16. At this time, the left I-shaped frame 51 and the right I-shaped frame 52 can be lifted upward to achieve the folding of the left I-shaped frame 51 and the right I-shaped frame 52. When folding, the left I-shaped frame 51 and the right I-shaped frame 52 drive the left support rod 6, the right support rod 7 and the two hinged connecting rods 8 of the front support assembly 1 and the rear support assembly 2 to fold, thereby realizing the folding of the diaper changing table. After the left I-shaped frame 51 and the right I-shaped frame 52 are folded, under the action of the return spring 20, the multiple engagement grooves 171 of the engagement member 17 re-engage with the multiple first engagement portions 151 of the left rotating member 15 and the multiple second engagement portions 161 of the right rotating member 16.

[0036] When the diaper table needs to be stored or packed, the lower connecting rod 22 is removed before folding, and then all the upper connecting rods 21 are removed. Then, the diaper table is folded according to the above steps. After the diaper table is folded, the folded front support assembly 1 and the rear support assembly 2 are further folded relative to the left surrounding rod 3 and the right surrounding rod 4. In this way, the diaper table is double folded in the width direction and the height direction, which greatly reduces the volume of the diaper table after folding.

[0037] When the diaper changing table needs to be reused, the front supporting assembly 1 and the rear supporting assembly 2 are unfolded relative to the left surrounding rod 3 and the right surrounding rod 4, and then the buttons 18 on the two left rotating members 15 are pressed down to unfold the left I-shaped frame 51 and the right I-shaped frame 52. When unfolding, the left I-shaped frame 51 and the right I-shaped frame 52 drive the left supporting rod 6, the right supporting rod 7 and the two hinged connecting rods 8 of the front supporting assembly 1 and the rear supporting assembly 2 to unfold. After the diaper changing table is unfolded, all the upper connecting rods 21 are installed, and then all the lower connecting rods 22 are installed, thereby completing the unfolding of the diaper changing table.

[0038] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
