[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] This utility model provides a technical solution: a foldable diaper changing table, such as... Figure 1 , Figure 11 As shown, it includes a folding support structure 1, a folding shelf 2 on the folding support structure 1, a pair of folding devices 3 inside the folding shelf 2, a secondary folding shelf 4 on one side of the folding shelf 2, and a moving mechanism 6 below the folding support structure 1.

[0020] like Figures 5-8As shown, the folding device 3 includes a first movable plate 301 and a second movable plate 302. A connecting piece 303 connects the tops of the first movable plate 301 and the second movable plate 302. Both the first movable plate 301 and the second movable plate 302 have square grooves 304 on their upper parts.

The first movable plate 301 has a support hole 306, and the second movable plate 302 has a through hole 307. Mounting plate 308 is provided on the side of component 301 away from movable plate 302. Mounting plate 308 has a mounting groove 309 on its upper part. Mounting plate 302 has mounting plate 310 on the side of movable plate 302 away from movable plate 301. An L-shaped flat strip 311 is connected to the top of mounting plate 310. The other end of the L-shaped flat strip 311 extends into the square groove 304 of movable plate 302 and is connected to a stop plate 312. The other end of the stop plate 312 engages with the mounting groove 309. Mounting plate 308 has a connecting hole 313, and mounting plate 310 has a connecting hole 314. A movable rivet 315 is located in connecting hole 313. The other end of the movable rivet 315 passes through a support hole 306 and a movable through hole 307, and connects to connecting hole 314. Mounting plate 308 has a pair of positioning holes 316, and mounting plate 310 has a pair of positioning holes 317. A guide rivet 318 is located in positioning hole 316. The other end of 18 passes through the guide hole 305 and is connected to the second positioning hole 317. The movable rivet 315 is fitted with a return spring 319. One end of the return spring 319 is connected to the second mounting plate 310, and the other end of the return spring 319 passes through the movable through hole 307 and abuts against the support hole 306. The return spring 319 can return to its original position when unfolded, which helps the diaper changing table to unfold automatically. The bottom sides of the movable plate 1 301 and the movable plate 2 302 are provided with pin holes 320.

[0021] like Figure 2 As shown, the folding support structure 1 includes a U-shaped support frame 101 and a U-shaped support frame 2 102. A pair of rotating connectors 103 are respectively disposed at the intersection of the U-shaped support frame 101 and the U-shaped support frame 2 102. A hinge plate 104 is provided below the rotating connector 103. One end of the hinge plate 104 is hinged to the U-shaped support frame 101, and the other end of the hinge plate 104 is hinged to the U-shaped support frame 2 102.

[0022] like Figure 9As shown, the secondary folding frame 4 includes a U-shaped connecting frame 401. Both ends of the U-shaped connecting frame 401 are hinged to the second U-shaped support frame 102. The second U-shaped support frame 102 has positioning pins 402 on both sides. The U-shaped connecting frame 401 has limiting pins 403 on both sides. A positioning connector 404 is provided between the positioning pins 402 and the limiting pins 403. The positioning connector 404 has a hinge hole 405 and a limiting groove 406. The hinge hole 405 is hinged to the positioning pin 402. The limiting pin 403 is movably disposed in the limiting groove 406.

[0023] like Figure 9 As shown, a special basin 7 can be placed on the U-shaped connecting frame 401. The U-shaped connecting frame 401 and the rim of the special basin 7 are matched so that the special basin 7 is stably placed on the U-shaped connecting frame 401.

[0024] like Figure 3 , Figure 4 As shown, a pin 5 is provided between a pair of pin holes 320 on the movable plate 1 301 and the movable plate 2 302. The folding shelf 2 includes a folding frame 1 201 and a folding frame 2 202. Folding connecting rods 1 207 are provided on both sides of the folding frame 1 201. A pair of movable holes 1 205 are provided at the end of the folding connecting rod 1 207 near the end of the folding frame 2 202. Folding connecting rods 2 208 are provided on both sides of the folding frame 2 202. A pair of movable holes 2 206 are provided at the end of the folding connecting rod 2 208 near the end of the folding frame 1 201. Movable holes 1 205 and 2 206 are respectively sleeved on the pins 5 on both sides of the folding device 3. A pair of rotating rods 1 203 are provided at the other end of the folding frame 1 201. The rotating rods 1 203 are hinged to the U-shaped support frame 1 101. A pair of rotating rods 2 204 are provided at the other end of the folding frame 2 202. The rotating rods 2 204 are hinged to the U-shaped support frame 2 102.

[0025] like Figure 10 As shown, the moving mechanism 6 includes a connecting sleeve 601, which is respectively sleeved on the bottom end of the first U-shaped support frame 101 and the second U-shaped support frame 102. The bottom of the connecting sleeve 601 is movably connected to a movable wheel 602.

[0026] In practice, when unfolding is required: pull outwards the U-shaped support frame 101 and U-shaped support frame 202, and the folding support structure 1 unfolds to form a stable base. Simultaneously pull the folding frame 1 201 and folding frame 202, and they rotate around the pin 5 to unfold, gradually approaching a horizontal state. During this process, the return spring 319 of the folding device 3 is released from the compressed state and quickly returns to its original position due to its own elasticity. The resulting thrust acts directly on the movable plate 1 301 and movable plate 2 302, which not only helps to accelerate the unfolding of the folding frame 1 201 and folding frame 2 202, reducing the force required for manual pulling, but also makes it easier for the diaper changing table to transition to a horizontal unfolding state, achieving a semi-automatic unfolding effect. At the same time, as the spring continues to rebound, it will further push the movable plate 1 301 and movable plate 2 302 to move, ultimately causing the abutment plate 312 to move precisely to the bottom of the folding frame 1 201 and folding frame 202, that is, above the connection position with the pin 5, and firmly abut against the two folding frames.

[0027] Once unfolded, it can be moved via the movable wheel 602 of the bottom moving mechanism 6, and the connecting cylinder 601 drives the movable wheel 602 to complete the turning action.

[0028] The supporting force of the stop plate 312, combined with the elastic force of the return spring 319, locks the first folding frame 201 and the second folding frame 202 in a horizontal state, completing the unfolding of the diaper changing table and enabling diaper changing operations.

[0029] As the U-shaped support frame 101 and the U-shaped support frame 2 102 unfold, the U-shaped connecting frame 401 is driven to unfold around the hinge point with the U-shaped support frame 2 102. During the unfolding process, the limiting pin 403 is movably set in the limiting groove 406 of the positioning connector 404. The limiting groove 406 restricts the movement range of the limiting pin 403, ensuring that the U-shaped connecting frame 401 remains stable after unfolding to a suitable angle, forming a side auxiliary shelf and completing the overall unfolding.

[0030] When folding is required: Pressing the mounting plate 310 causes movable plates 301 and 302 to slide along the guide rivet 318 toward the L-shaped flat bar 311. The return spring 319 is compressed by the movable plate 301, and the abutment 312 disengages from the bottom of the folding connecting rods 207 and 208. Finally, the movable plates 301 and 302 move from the initial position of the abutment 312 to the upper part of the L-shaped flat bar 311. Since the folding connecting rods 207 and 208 lose the bearing support of the abutment 312, a space is created below them, thus releasing the support locking state.

[0031] Folding frame 1 201 and folding frame 202, having lost the support of the abutment plate 312, gain room to move around the hinge point of the pin 5 and can rotate inwards to fold. Simultaneously, U-shaped support frame 1 101 and U-shaped support frame 2 102 retract inwards. At the same time, U-shaped connecting frame 401, driven by U-shaped support frame 2 102, folds around the hinge point, and the limiting pin 403 moves along the limiting groove 406 to its initial position, completing the overall folding and storage, reducing space occupation.
