For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] like Figure 1-Figure 5 As shown, a foldable children's climbing ladder has an unfolded state (such as Figure 1 and Figure 2 as shown) and folded state (as shown Figure 5 The child climbing ladder of this embodiment mainly includes: a front support leg 1, a rear support leg 2, a first pedal 3, an upper support rod 4, an upper frame 5 and a second pedal 6.

[0052] One end of the front support leg 1 and the rear support leg 2 are rotatably connected, and the other ends of both are configured as support ends, and the support ends of the front support leg 1 and the rear support leg 2 are used to support the ground. The first pedal 3 is rotatably connected to the front support leg 1 and is movably connected to the rear support leg 2. It should be explained that a sliding member 30 is configured on the first pedal 3, and the sliding member 30 is preferably a sliding sleeve. The sliding member 30 is rotatably connected to the first pedal 3, and during the folding and unfolding process of the children's climbing ladder, the sliding member 30 can slide up and down relative to the rear support leg 2. In actual use, when the children's climbing ladder is folded, the sliding member 30 slides downward relative to the rear support leg 2, and the first pedal 3 moves from a horizontal state to a substantially vertical state, ensuring that the first pedal 3 does not occupy other space; when the children's climbing ladder is unfolded, the sliding member 30 slides upward relative to the rear support leg 2, and the first pedal 3 moves to a horizontal state.

[0053] One end of the upper support rod 4 is rotatably connected to the front support leg 1. Specifically, one end of the upper support rod 4, the rear support leg 2 and the front support leg 1 each has a joint, and the joints of the three are rotatably connected to each other. The upper frame 5 is arranged at the top of the upper support rod 4. When a child stands on the first pedal 3, the upper frame 5 can prevent the child from falling from the first pedal 3, thereby protecting the child's safety. The upper frame 5 is rotatably connected to the upper support rod 4.

[0054] In actual use, when the children's climbing ladder switches from the unfolded state to the folded state: the upper frame 5 rotates and folds onto the upper support rod 4; the upper support rod 4 and the rear support leg 2 rotate and fold relative to the front support leg 1, and move closer to the front support leg 1; the first pedal 3 rotates and folds relative to the front support leg 1. That is, the upper support rod 4, the rear support leg 2 and the first pedal 3 can all move closer to the front support leg 1, ensuring that the size of the children's climbing ladder after folding is small, the space occupied is small, and it is convenient to transport and store.

[0055] like Figure 6 , Figure 8 Combined with Figure 5 As shown, the rear support leg 2 is provided with a first locking member 21 and a push member 22, wherein the first locking member 21 is a locking block, and the first locking member 21 is movably arranged between the sliding member 30 and the rear support leg 2. The sliding member 30 is provided with a corresponding locking groove, and the locking block can be locked into the locking groove to lock the sliding member 30 on the rear support leg 2. The push member 22 is movably arranged on the rear support leg 2, and is used to push the first locking member 21 to unlock the first locking member 21. During use, when the children's climbing ladder is in the unfolded state, the first locking member 21 locks the sliding member 30 on the rear support leg 2 to ensure the structural stability of the first pedal 3 at this time. When the upper support rod 4 rotates and folds, the upper support rod 4 drives the push member 22 to push the first locking member 21, so that the first locking member 21 releases the lock on the sliding member 30, so as to facilitate the folding of the first pedal 3.

[0056] Specifically, the first locking member 21 has a first inclined wall 211, and the push member 22 has a second inclined wall 221, and the second inclined wall 221 has the same inclined direction as the first inclined wall 211. When the upper support rod 4 drives the push member 22 to push the first locking member 21, the second inclined wall 221 pushes the first inclined wall 211, so that the first locking member 21 retracts into the rear support leg 2, and the first locking member 21 is disengaged from the locking groove on the sliding member 30, and the first locking member 21 releases the locking of the sliding member 30. Among them, a second spring 23 is provided between the sliding member 30 and the first locking member 21, and the two ends of the second spring 23 are respectively against the first locking member 21 and the sliding member 30. When the pushing member 22 pushes the first locking member 21 to unlock the first locking member 21, the first locking member 21 compresses the second spring 23. The elastic force of the second spring 23 makes the first locking member 21 tend to move toward the locking groove side on the sliding sleeve, thereby ensuring the structural stability of the first locking member 21 when it is locked in the locking groove, and ensuring that the first locking member 21 can be reset and locked into the locking groove on the sliding sleeve after the children's climbing ladder is unfolded.

[0057] More specifically, if Figure 6 As shown, a slot 40 is provided on the upper support rod 4. When the children's climbing ladder is in the unfolded state, one end of the push member 22 is engaged in the slot 40. When the children's climbing ladder is folded, the upper support rod 4 is rotated and folded, and the slot 40 rotates relative to the push member 22, so that the push member 22 is separated from the slot 40. The joint at the end of the upper support rod 4 presses the push member 22, so that the push member 22 pushes the first locking member 21, and the first locking member 21 is separated from the locking slot provided on the sliding member 30. The two sides of the slot 40 have a first inclined surface 401 and a second inclined surface 402 arranged opposite to each other. The slot 40 is roughly V-shaped, and the push member 22 has a third inclined surface 222 and a fourth inclined surface 223. The first inclined surface 401 and the third inclined surface 222 are movably opposed to each other, and the second inclined surface 402 and the fourth inclined surface 223 are movably opposed to each other, so that during use, the end of the push member 22 and the slot 40 can be smoothly squeezed and separated, or smoothly engaged.

[0058] like Figure 7 Combined with Figure 1-Figure 5As shown, a second locking member 11 is movably provided between the upper support rod 4 and the front support leg 1, and the second locking member 11 is a locking gear. When the children's climbing ladder is in the unfolded state, the second locking member 11 locks the upper support rod 4 on the front support leg 1, and the upper support rod 4 cannot be folded at this time. When the second locking member 11 is driven to release the lock on the upper support rod 4, the upper support rod 4 can be rotated and folded relative to the front support leg 1. Among them, an unlocking button 12 is provided on the front support leg 1, and the unlocking button 12 and the second locking member 11 are movably abutted. A first spring 13 is provided between the second locking member 11 and the upper support rod 4, and the two ends of the first spring 13 are respectively abutted against the upper support rod 4 and the second locking member 11. During use, the unlocking button 12 is pressed, and the unlocking button 12 pushes the second locking member 11, causing the second locking member 11 to move away from the front supporting leg 1, and the second locking member 11 releases the lock on the upper supporting rod 4, and the second locking member 11 will compress the first spring 13. The elastic force of the first spring 13 can ensure that the second locking member 11 has a tendency to move to the locked state. The first spring 13 can also quickly reset the second locking member 11 and the unlocking button 12 after the unlocking button 12 unlocks the second locking member 11.

[0059] Optionally, in the children's ladder of this embodiment, a second pedal 6 is provided on the front supporting leg 1, and the second pedal 6 is below the first pedal 3. Children can climb onto the first pedal 3 from the second pedal 6, which is convenient for children to climb up step by step and avoids the second pedal 6 being too high and the children being unable to climb up directly.

[0060] During use, when the children's ladder needs to be switched from the unfolded state to the folded state: first, the upper frame 5 is rotated and folded onto the upper support rod 4. Then, the unlocking button 12 is pressed, and the unlocking button 12 pushes the second locking member 11, so that the second locking member 11 releases the lock on the upper support rod 4, and the upper support rod 4 can fall back and rotate relative to the front support leg 1. In the process of falling back (i.e., rotating and folding) the upper support rod 4, the pushing member 22 is squeezed, so that the pushing member 22 pushes the first locking member 21, and the first locking member 21 is disengaged from the locking groove on the sliding member 30, i.e., the first locking member 21 releases the lock on the sliding member 30. When the upper support rod 4 falls back (i.e., rotates and folds) and hits the first pedal 3, the sliding member 30 on the first pedal 3 slides downward, and the first pedal 3 rotates relative to the front support leg 1, until the first pedal 3, the upper support rod 4 and the rear support leg 2 are all close to the front support leg 1, rotated and folded to the front support leg 1, and the children's ladder is folded. The children's climbing ladder is convenient to fold and fold. Conversely, the unfolding action of the children's climbing ladder is opposite to the folding action.
