Description

一种婴儿车防夹手关节结构
技术领域
本实用新型涉及一种婴儿车防夹手关节结构,具体地说是一种可以使婴儿车在展开和收合时没有夹手间隙的关节结构。
背景技术
婴儿车习惯于携带和收藏的对体积小的需求,基本上设计有收合折叠功能,并逐步强化起收折方便和安全性功能。习用之婴儿车关节,虽然可达到收合和展开的功能,但在收合和展开的过程中,有裸露或存在剪切及夹手空间,若操作者和小孩不小心,有可能会把手指伸入关节中,而造成夹伤手指的危险性。
发明内容
本实用新型的目的是提供一种收折方便、使用安全的婴儿车防夹手关节结构。
本实用新型的目的通过以下技术方案来实现。
一种婴儿车防夹手关节结构,其特征在于:所述婴儿车防夹手关节结构包括上关节、下关节、关节调节装置、收车手拉钩与收车钢绳,关节调节装置连接上关节与下关节,上关节与下关节可相对旋转地安装在一转轴上,收车钢绳的一端与收车手拉钩连接,另一端与关节调节装置连接。
所述关节调节装置包括关节转轮、关节传动轮、关节弹簧与关节齿轮,关节传动轮可移动地安装在关节齿轮与上关节之间的转轴上并与关节齿轮贴合在一起,关节转轮可转动地安装在关节传动轮和上关节之间的转轴上并与上关节内部贴合在一起,关节弹簧的两端分别顶压在下关节与关节齿轮上,关节转轮与收车钢绳连接,关节转轮与关节传动轮之间设有推顶斜面,关节齿轮的周缘轮廓设有齿,上关节和下关节内部具有与齿配合的齿形槽。
所述上关节内设有两导柱,关节传动轮设有两导槽,两导柱与两导槽配合。
本实用新型与现有技术相比具有以下优点。
本实用新型婴儿车防夹手关节结构具有收折方便、使用安全的优点。

具体实施方式
下面结合附图对本实用新型婴儿车防夹手关节结构作进一步详细描述。
如图1、图2、图3与图4所示,本实用新型婴儿车防夹手关节结构包括上关节1、下关节2、关节调节装置、收车手拉钩3与收车钢绳4,关节调节装置连接上关节与下关节,上关节与下关节可相对旋转地安装在一转轴上,收车钢绳的一端与收车手拉钩连接,另一端与关节调节装置连接。关节调节装置包括关节转轮5、关节传动轮6、关节弹簧7与关节齿轮8,关节传动轮可移动地安装在关节齿轮与上关节之间的转轴上并与关节齿轮贴合在一起,关节转轮可转动地安装在关节传动轮和上关节之间的转轴上并与上关节内部贴合在一起,关节弹簧的两端分别顶压在下关节与关节齿轮上,关节转轮与收车钢绳连接,关节转轮与关节传动轮之间设有推顶斜面,关节齿轮的周缘轮廓设有齿,上关节和下关节内部具有与齿配合的齿形槽。上关节内设有两导柱,关节传动轮设有两导槽,两导柱与两导槽配合。
本实用新型婴儿车防夹手关节结构在操作时,收车手拉钩往上拉,通过收车钢绳带动关节转轮动,关节转轮的推顶斜面推顶关节传动轮的推顶斜面,转化为轴向运动,把关节齿轮分离上关节,此时关节组处于解锁状态,婴儿车可折叠。本实用新型婴儿车防夹手关节结构在操作时,直接相对展开手把管和前脚管,关节齿轮在关节弹簧的作用下回位,锁定关节,婴儿车处于展开状态。本实用新型婴儿车防夹手关节结构在操作时,上下关节为同心圆相对转动,不产生任何间隙或剪切,从而不会造成夹操作者或小孩手的危险。此防夹手关节结构操作方便,且使用安全。
