[0003] Existing children's climbing ladders often have poor ground support from their supporting legs, sometimes causing them to tip backward. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a support foot for a children's climbing ladder with good support stability and convenient use, as well as a children's climbing ladder.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a support leg for a children's climbing ladder, comprising:

[0006] The support leg body has a support part disposed on it, and the support leg body can be supported on the ground through the support part;

[0007] An auxiliary support is movably mounted on the main body of the support leg. The auxiliary support can be extended outward from the support portion, and after being extended, the auxiliary support at least partially protrudes from the support portion.

[0008] The support foot can be supported on the ground by the support part and the auxiliary support.

[0009] Furthermore, the auxiliary support is movable at the support portion;

[0010] The two ends of the main body of the support foot are respectively provided with a support part, and the auxiliary support is movably provided at each of the two support parts.

[0011] Furthermore, the auxiliary support is rotatably mounted on the support leg body;

[0012] The auxiliary support can rotate outward relative to the main body of the support leg and unfold, and the auxiliary support can rotate inward relative to the main body of the support leg and fold.

[0013] Furthermore, a first elastic element is provided between the auxiliary support and the main body of the support leg, and the elastic force of the first elastic element causes the auxiliary support to have a tendency to maintain movement in its unfolding direction;

[0014] When the auxiliary support folds towards the side closer to the main body of the support foot, the first elastic element is compressed.

[0015] Furthermore, a protrusion protrudes from the auxiliary support, and a corresponding arc-shaped groove is provided on the main body of the support leg, with the protrusion located in the arc-shaped groove;

[0016] When the auxiliary support rotates relative to the main body of the support foot, the protrusion slides along the arc-shaped groove.

[0017] Furthermore, the first elastic element is configured as a spring, with one end of the spring abutting against the auxiliary support and the other end of the spring abutting against the protrusion.

[0018] Furthermore, the support leg body is provided with a receiving groove, and the receiving groove has a side opening;

[0019] The auxiliary support is rotatably disposed in the receiving groove and can be rotated into or out of the receiving groove from the side opening.

[0020] Furthermore, the auxiliary support has an arc-shaped sidewall and a filled sidewall, the arc-shaped sidewall being adjacent to the filled sidewall;

[0021] The center of the arc-shaped sidewall coincides with the rotation center of the auxiliary support;

[0022] When the auxiliary support rotates inward and folds into the receiving groove, the filling sidewall seals the side opening and is flush with the side of the support leg body.

[0023] Furthermore, the auxiliary support is slidably disposed on the support leg body, and its sliding direction is perpendicular to the support leg body;

[0024] A second elastic element is provided between the auxiliary support and the main body of the support foot. The two ends of the second elastic element abut against the main body of the support foot and the auxiliary support, respectively. The elastic force of the second elastic element causes the auxiliary support to have a tendency to slide outward.

[0025] This utility model also proposes a children's climbing ladder, comprising:

[0026] The system includes a front support, a rear support, a pedal, and an upper frame. The front support and the rear support are connected. The pedal is located between the front support and the rear support. The upper frame is located on the front support and above the pedal.

[0027] At least the bottom of the rear support is provided with the support feet of the aforementioned children's climbing ladder.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0051] Example 1:

[0052] like Figures 2-6 and combined Figure 1 As shown, the support leg of the children's climbing ladder in this embodiment mainly includes: a support leg body 1 and an auxiliary support 2. The support leg body 1 is equipped with a support portion 10, and the support leg body 1 can be supported on the ground by the support portion 10. The auxiliary support 2 is movably mounted on the support leg body 1, and the auxiliary support 2 can extend outward from the support portion 10, with at least a portion of the auxiliary support 2 protruding from the support portion 10 after extension. In actual use, the support leg is supported on the ground by the support portion 10 and the auxiliary support 2 working together.

[0053] Specifically, in this embodiment, the auxiliary support 2 is rotatably disposed at the support part 10. Each end of the support foot body 1 is provided with a support part 10, and each of the two support parts 10 is movably provided with an auxiliary support 2. During use, the two auxiliary supports 2 extend outward from both ends of the support foot body 1 and support the ground to ensure the support effect of the support foot, thereby effectively improving the stability of the children's climbing ladder.

[0054] In this embodiment, an auxiliary support 2 is movably provided on the main body 1 of the support foot, and the auxiliary support 2 can be deployed from the support part 10. By supporting the main body 10 and the auxiliary support 2 together, the support on the ground can be effectively improved, ensuring the stability of the children's climbing ladder and reducing the risk of the children's climbing ladder tipping backward.

[0055] like Figures 3-6 As shown, the auxiliary support 2 is rotatably mounted on the support leg body 1, specifically, the auxiliary support 2 is hinged to the support leg body 1 via a rotating sleeve. The auxiliary support 2 can rotate outward relative to the support leg body 1, thereby improving the support effect of the support leg. Furthermore, the auxiliary support 2 can rotate inward relative to the support leg body 1 and fold back. When the auxiliary support 2 is not needed, it can be folded back into the support leg body 1 without occupying additional space, making it convenient to use.

[0056] The support leg body 1 has a receiving groove with a side opening 120 communicating with it. The auxiliary support 2 is rotatably disposed in the receiving groove and can be rotated in or out of the receiving groove through the side opening 120. When the auxiliary support 2 is needed, it can protrude from the receiving groove through the side opening 120. When the auxiliary support 2 is not needed, it can be pushed inward to completely fold and store it in the receiving groove.

[0057] Furthermore, the auxiliary support 2 in this embodiment has an arc-shaped sidewall 21 and a filling sidewall 22. The arc-shaped sidewall 21 and the filling sidewall 22 are adjacent to each other, and the center of the arc-shaped sidewall 21 coincides with the rotation center of the auxiliary support 2, ensuring that the auxiliary support 2 will not interfere with the movement of the support leg body 1 during the rotation of the auxiliary support 2. When the auxiliary support 2 rotates inward and folds into the receiving groove, the filling sidewall 22 blocks the side opening 120 and is flush with the side of the support leg body 1. After the auxiliary support 2 is completely received into the receiving groove, the side opening 120 is blocked, which can ensure the overall appearance consistency of the support leg body 1.

[0058] A first elastic element 3A is provided between the auxiliary support 2 and the support leg body 1. The elastic force of the first elastic element 3A causes the auxiliary support 2 to tend to move in its unfolding direction. When the auxiliary support 2 is folded towards the support leg body 1, the first elastic element 3A is compressed. The provision of the first elastic element 3A ensures that the auxiliary support 2 remains in a fully unfolded state, thereby ensuring a large contact area with the ground and improving support stability.

[0059] A protrusion 20 protrudes from the auxiliary support 2, and a corresponding arc-shaped groove 11 is provided on the support leg body 1. The center of the arc-shaped groove 11 coincides with the rotation center of the auxiliary support 2, and the protrusion 20 is located in the arc-shaped groove 11. In actual use, when the auxiliary support 2 rotates relative to the support leg body 1, the protrusion 20 slides along the arc-shaped groove 11. When the protrusion 20 reaches the end of the arc-shaped groove 11, it can limit the extreme position of the auxiliary support 2, that is, the arc-shaped groove 11 can determine the size of the rotation stroke of the auxiliary support 2. In this embodiment, the first elastic element 3A is configured as a spring. One end of the spring abuts against the auxiliary support 2, and the other end of the spring abuts against the protrusion 20. The spring is tensioned at one end of the protrusion 20 and the arc-shaped groove 11, and it always pushes the protrusion 20 outward, that is, pushes the auxiliary support 2 outward.

[0060] Of course, in addition to configuring the first elastic element 3A as a spring, the first elastic element 3A can also be configured as a torsion spring, but the purpose of setting them is to make the auxiliary support 2 have a tendency to move in its unfolding direction.

[0061] Example 2:

[0062] The support legs of the children's climbing ladder in this embodiment mainly include: a support leg body 1 and an auxiliary support 2. The support leg body 1 is equipped with a support portion 10, which supports the support leg body 1 on the ground. The auxiliary support 2 is telescopically mounted on the support leg body 1, and can slide outward from the support portion 10, with at least a portion of the auxiliary support 2 protruding from the support portion 10 after deployment. In actual use, the support leg is supported on the ground by the combined action of the support portion 10 and the auxiliary support 2.

[0063] Furthermore, a second elastic element 3B is provided between the auxiliary support 2 and the main body 1 of the support foot. The two ends of the second elastic element 3B abut against the main body 1 of the support foot and the auxiliary support 2, respectively. The elastic force of the second elastic element 3B causes the auxiliary support 2 to tend to slide outwards. In actual use, when the auxiliary support 2 retracts or folds inwards towards the main body 1 of the support foot, the second elastic element 3B is compressed. Similarly, the provision of the second elastic element 3B ensures that the auxiliary support 2 remains in a fully extended state, thereby ensuring a large contact area between the auxiliary support 2 and the ground and improving support stability.

[0064] The difference between the support foot of the children's climbing ladder in this embodiment and that in embodiment one is that the auxiliary support 2 in this embodiment is slidably mounted on the support foot body 1, and its sliding direction is perpendicular to the support foot body 1. In contrast, the auxiliary support 2 in embodiment one is rotatably mounted on the support foot body 1. Compared with the irregular auxiliary support 2 in embodiment one, the auxiliary support 2 in this embodiment has a simpler structure, is easier to manufacture, and the corresponding receiving groove on the support foot body 1 is also easier to process.

[0065] like Figure 1 As shown, when the support legs of Embodiment 1 or Embodiment 2 are applied to a children's climbing ladder, the children's climbing ladder mainly includes:

[0066] The ladder consists of a front support 4, a rear support 5, a step 6, and an upper frame 7. The front support 4 and the rear support 5 are connected, and generally, they are rotatably connected to facilitate folding. The step 6 is located between the front support 4 and the rear support 5, and can be folded along with the ladder. The upper frame 7 is located on the front support 4 and above the step 6. Generally, the upper frame 7 is rotatably located on the front support 4, and can be folded onto the front support 4 when the ladder needs to be folded. At least the bottom of the rear support 5 has a support leg as described in Embodiment 1 or Embodiment 2. Generally, the front support 4 and the rear support 5 are tubular components, and the two ends of the support leg body 1 have cylindrical plugs protruding upwards, which can be directly inserted into the two tubular components of the rear support 5 for a fixed connection.

[0067] In actual use, when a child stands on step 6, the center of gravity of the entire ladder is close to the rear. To prevent the ladder from tipping backward, a support foot, as described in Embodiment 1 or Embodiment 2, is installed at the bottom of the rear support 5. Alternatively, the bottom of the front support 4 can also be configured with the support foot described in Embodiment 1 or Embodiment 2 to improve the front support effect.

[0068] In this design, an auxiliary support 2 is movably provided on the main support leg 1, and the auxiliary support 2 can be deployed from the support part 10. With the support part 10 on the main support body and the auxiliary support 2 working together, the support on the ground can be effectively improved, ensuring the stability of the children's climbing ladder and reducing the risk of the children's climbing ladder tipping backward.
