Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See Figures 1-5 As shown, this utility model provides a child-friendly stepladder to prevent finger pinching, comprising:

[0033] The first crossbeam 1 has first columns 4 connected to the bottom surfaces of both ends of the first crossbeam 1, and several first pedals 5 are connected between the two first columns 4.

[0034] The second crossbeam 2 has second columns 7 connected to the bottom surfaces of both ends of the second crossbeam 2, and several second pedals 8 are connected between the two second columns 7.

[0035] A limiting rope 6 is connected between the first pedal 5 and the second pedal 8, which are at the same height.

[0036] A rotating connector 3 is connected between the first crossbeam 1 and the second crossbeam 2. The rotating connector 3 is embedded in the surface of the first crossbeam 1 and the second crossbeam 2 so that the first crossbeam 1 abuts against the second crossbeam 2 when the first crossbeam 1 and the second crossbeam 2 are rotated and unfolded.

[0037] In this embodiment, during use, the first crossbeam 1 and the second crossbeam 2 can be rotated by rotating the connecting member 3. The first crossbeam 1 and the second crossbeam 2 are rotated and unfolded. The unfolding limit of the first crossbeam 1 and the second crossbeam 2 is achieved by the limiting rope 6. The first crossbeam 1 and the second crossbeam 2 abut against each other. Children can climb up by using the first step 5 and the second step 8. Since the first crossbeam 1 and the second crossbeam 2 abut against each other, children's fingers will not be inserted between the first crossbeam 1 and the second crossbeam 2. At this time, when the first crossbeam 1 and the second crossbeam 2 are closed by external force, it will not cause pinching injury to children's fingers.

[0038] By embedding a rotating connector 3 on the surface of the first crossbeam 1 and the second crossbeam 2, the first crossbeam 1 and the second crossbeam 2 can be made to abut against each other when the first crossbeam 1 and the second crossbeam 2 are rotated and unfolded. Since the first crossbeam 1 and the second crossbeam 2 abut against each other, it can effectively prevent children's fingers from being pinched, and the safety is high.

[0039] In an optional embodiment of this utility model, the width of the first column 4 is equal to the width of the first crossbeam 1, and the width of the second column 7 is equal to the width of the second crossbeam 2.

[0040] In this embodiment, the above structure can reduce the gap between the first column 4 and the second column 7 after the first crossbeam 1 and the second crossbeam 2 are closed, thereby preventing children's fingers from being pinched by inserting them into the gap between the first column 4 and the second column 7.

[0041] In an optional embodiment of this utility model, multiple rotating connectors 3 are provided and are evenly distributed along the length direction of the first crossbeam 1.

[0042] In this embodiment, the connection stability of the first crossbeam 1 and the second crossbeam 2 can be improved by setting multiple rotating connectors 3.

[0043] In an optional embodiment of this utility model, the rotating connector 3 includes:

[0044] The first connecting plate 31 is mounted on the first mounting groove 11 on the surface of the first crossbeam 1 by screws. The first connecting plate 31 has a plurality of first connecting sleeves 34 formed on the edge near the second crossbeam 2.

The second connecting plate 36 has a plurality of second connecting sleeves 37 formed on the edge near the first crossbeam 1. The second connecting sleeves 37 are staggered with the first connecting sleeves 34 and are coaxial with the first connecting sleeves 34.

[0046] The connecting shaft 33 passes through the first connecting sleeve 34 and the second connecting sleeve 37 in one pass.

[0047] In this embodiment, the rotational engagement between the first connecting shaft 33, the first connecting sleeve 34, and the second connecting sleeve 37 enables the rotation of the first connecting plate 31 and the second connecting plate 36, thereby enabling the rotation of the first crossbeam 1 and the second crossbeam 2. Since the first connecting plate 31 and the second connecting plate 36 are located inside the first mounting groove 11 and the second mounting groove 21 respectively, the gap between the first crossbeam 1 and the second crossbeam 2 can be reduced, allowing the first crossbeam 1 and the second crossbeam 2 to abut when rotated and unfolded. At the same time, the gap between the first crossbeam 1 and the second crossbeam 2 when closed can be reduced, preventing children's fingers from being pinched when inserted into the gap.

[0055] In an optional embodiment of the present invention, a first limiting plate 38 is formed on the edge of the first connecting plate 31 away from the second connecting plate 36. The first limiting plate 38 is located inside the first limiting groove 13, which is connected to the first mounting groove 11. A second limiting plate 39 is formed on the edge of the second connecting plate 36 away from the first connecting plate 31. The second limiting plate 39 is located inside the second limiting groove 23, which is connected to the second mounting groove 21.

[0056] In this embodiment, the stability of the first connecting plate 31 inside the first mounting groove 11 can be improved by the cooperation of the first limiting plate 38 and the first limiting groove 13; the stability of the second connecting plate 36 inside the second mounting groove 21 can be improved by the cooperation of the second limiting plate 39 and the second limiting groove 23.

[0057] In an optional embodiment of the present invention, the thickness of the first connecting plate 31 is equal to the depth of the first mounting groove 11; the thickness of the second connecting plate 36 is equal to the depth of the second mounting groove 21.
