Abstract
Description
Technical Field
[0001] This utility model relates to the field of children's products, specifically to a diaper changing table that has a smaller storage space when folded. Background Technology
[0002] A changing table is a piece of furniture specifically designed for changing diapers. Its main features include a height suitable for adults to stand while using it, and a height that also prevents the baby from rolling off, ensuring the baby's safety. Changing tables are usually equipped with a railing and safety harness. The railing prevents the baby from accidentally rolling off, while the safety harness secures the baby to the table, increasing safety during diaper changes. In addition, changing tables often have storage space, such as cabinets, drawers, or shelves, making it convenient for parents to store diapers, wipes, changes of clothes, and other baby supplies, improving the efficiency and convenience of diaper changing.
[0003] Existing changing tables consist of two U-shaped rods hinged together in an "X" shape, with a foldable support frame hinged between the upper parts of the two rods. When the 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 changing table. However, the height of the changing table after folding is still greater than its height when in use, which makes the changing table still relatively bulky when packaged and stored. Utility Model Content
[0004] This utility model provides a diaper changing table with a smaller storage space after folding, and its main purpose is to overcome the problem that the existing diaper changing table is still large in size after folding.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A diaper changing table with a smaller storage space after folding includes a front support assembly, a rear support assembly, a left side rail, a right side rail, and a centrally foldable support frame. Both the front and rear support assemblies can be automatically folded along with the support frame. The left side rail is located between the top left end of the front support assembly and the top left end of the rear support assembly, and the left ends of both the front and rear support assemblies are foldably connected to the left side rail. The right side rail is located between the top right end of the front and rear support assemblies, and the right ends of both the front and rear support assemblies are foldably connected to the right side rail. The left and right ends of the support frame are hinged to the bottom of the left and right side rails, respectively. A detachable left connecting rod is provided between the left ends of the front and rear support assemblies, and a detachable right connecting rod is provided between the right ends of the front and rear support assemblies.
[0007] Furthermore, both the front support assembly and the rear support assembly include a left support rod, a right support rod, and two hinged connecting rods. The left support rod and the right support rod are each provided with an upper sliding sleeve and a lower rod sleeve. The two hinged connecting rods are in an "X" shape and are hinged together at the middle. Each end of the hinged connecting rod corresponds to an upper sliding sleeve and a lower rod sleeve. The two ends of the two hinged connecting rods are respectively hinged to the corresponding upper sliding sleeve and lower rod sleeve. The upper sliding sleeve can slide along the corresponding left support rod and right support rod.

[0035] Reference Figure 1 The bottom of both the left support rod 6 and the right support rod 7 is provided with rollers 23, which facilitate the movement of the diaper changing table.
[0036] Reference Figures 1 to 10 The design principle of this utility model is as follows: When the diaper changing table is not in use and needs to be folded, press the buttons 18 on the two left rotating parts 15. The pressing part 181 on the button 18 pushes the biting part 17 to move inward, so that the multiple biting grooves 171 of the biting part 17 disengage from the multiple first biting parts 151 of the left rotating part 15 and only engage with the multiple second biting parts 161 of the right rotating part 16. At this time, lifting the left I-beam 51 and the right I-beam 52 upwards can realize the folding of the left I-beam 51 and the right I-beam 52. When the left I-beam 51 and the right I-beam 52 are folded, the left support rod 6 and the right support rod 7 of the front support assembly 1 and the rear support assembly 2 and the two hinged connecting rods 8 are folded, thereby realizing the folding of the diaper changing table. After the left I-beam 51 and the right I-beam 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 parts 151 of the left rotating member 15 and the multiple second engagement parts 161 of the right rotating member 16.
[0037] When the changing table needs to be stored or packaged, first remove the lower connecting rod 22 before folding it up, then remove all the upper connecting rods 21. Then, fold the changing table up according to the steps above. After the changing table is folded up, fold the folded front support assembly 1 and rear support assembly 2 further relative to the left and right side rods 3 and 4. This achieves double folding of the changing table in both the width and height directions, greatly reducing the volume of the changing table after folding.
[0038] When the changing table needs to be reused, the front support assembly 1 and the rear support assembly 2 are unfolded relative to the left and right side rails 3 and 4. Then, the buttons 18 on the two left rotating parts 15 are pressed down to unfold the left I-beam 51 and the right I-beam 52. When the left and right I-beam 51 and the right I-beam 52 unfold, they 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 unfold. After the changing table is unfolded, all the upper connecting rods 21 are installed, and then all the lower connecting rods 22 are installed to complete the unfolding of the changing table.
[0039] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
