用於兒童載具之支撐架的管件、支撐架及兒童載具Pipe fitting for supporting frame of child carrier, supporting frame and child carrier

本發明關於一種兒童用品領域，尤指一種用於兒童載具之支撐架的管件。The invention relates to the field of children's products, in particular to a tube used for a support frame of a child carrier.

如今，兒童載具多種多樣，且得到廣泛地使用，兒童載具上的支撐架的穩固性直接關係到兒童載具的安全。兒童經常會在兒童載具中跳躍，因此，兒童會對兒童載具在上下方向產生較大的衝擊力，現有技術中的兒童載具的支撐架的管件因不能承受較大的衝擊力，會導致其彎曲變形或斷裂，從而使得兒童載具會失去穩固的支撐，進而使得乘坐兒童摔跤或者不受控制地摔撞於兒童載具之堅硬的結構件上，從而受到傷害。現有技術中，管件通過整體性地增大管徑，或整體性地增加管件壁厚，來增強管件的剛度和慣性矩，從而提高管件的抗彎曲和抗衝擊能力，但是這種做法必然會使得管件製作成本增加，且由於管件尺寸的變化將使得其無法與標準的關節進行匹配連接，從而導致無法正常的更換和使用。Nowadays, there are many kinds of children's vehicles and they are widely used. The stability of the support frame on the children's vehicles is directly related to the safety of the children's vehicles. Children often jump in the child carrier. Therefore, the child will have a greater impact on the child carrier in the up and down direction. The pipes of the support frame of the child carrier in the prior art cannot withstand the greater impact force. As a result, the child carrier will be bent, deformed or broken, so that the child carrier will lose its firm support, and the child may fall or fall uncontrollably on the rigid structure of the child carrier, thereby being injured. In the prior art, pipes increase the pipe diameter or the wall thickness of the pipes as a whole to enhance the rigidity and moment of inertia of the pipes, thereby improving the bending resistance and impact resistance of the pipes. However, this approach will inevitably lead to The manufacturing cost of the pipe fitting increases, and the change in the size of the pipe fitting will make it unable to be matched and connected with the standard joint, resulting in the failure of normal replacement and use.

因此，極需一種能與標準的關節進行匹配連接，並且還能有效提高抗彎曲和抗衝擊能力的用於兒童載具之支撐架的管件。Therefore, there is a great need for a tube for the support frame of a child carrier that can be matched and connected with a standard joint and can effectively improve the resistance to bending and impact.
