 本发明的实施方式
以下实施例会结合附图对本发明进行详述，在附图或说明中，相似或相同的部分使用相同的标号，并且在实际应用中，各部件的形状、厚度或高度可扩大或缩小。本发明所列举的各实施例仅用以说明本发明，并非用以限制本发明的范围。对本发明所作的任何显而易知的修饰或变更都不脱离本发明的精神与范围。
实施例1
请参阅图1～2，本发明实施例中，一种能够自调节的安全型儿童早教用助行器，包括支撑体以及安装于支撑体底部的行走机构；所述支撑体包括上环体1和下环体2，上环体1和下环体2之间通过多个连接杆3连接；所述上环体1的内圈中设置有支撑环4，支撑环4通过连接架42与上环体1连接；所述支撑环4的内圈中设置有至少三个沿周向等距布设的活动柱5，支撑环4上开设有与活动柱5相适配的通孔41，活动柱5滑动穿设在通孔41中且通过移动组件驱动，活动柱5位于支撑环4内圈的一端固定有限位板51，使用时，将幼儿置于支撑环4的包设范围内，然后由移动组件通过活动柱5带动限位板51移动，从而对多个限位板51所构成的限位空间的大小进行调整，保证对于儿童的防护效果。
进一步的，所述限位板51呈弧形且其内弧面上设置有软垫511，提高使用的舒适度。
请参阅图1和图3，本实施例中，所述移动组件包括腿部套环6以及与活动柱5一一对应设置的多个驱动齿轮8；所述腿部套环6设置在上环体1和下环体2之间，腿部套环6通过弹性件61与连接杆3连接；所述驱动齿轮8设置在开设于上环体1的空腔11中，活动柱5远离限位板51的一端伸入到空腔11中且通过直齿段512与驱动齿轮8啮合，驱动齿轮8的两端通过转轴81转动连接空腔11的壳壁；一侧所述转轴81的轴体外围套设有复位发条811，复位发条811的一端固定在转轴81上，复位发条811的另一端固定在空腔11的壳壁上，从而当转轴81转动时，复位发条811会收紧，另一侧所述转轴81的轴体外围缠绕有牵引绳7，牵引绳7的另一端固定在腿部套环6上，使用时，将儿童的腿部穿过腿部套环6，从而带动腿部套环6向下移动，腿部套环6拽拉牵引绳7从而带动转轴81顺时针转动（以图示左侧的驱动齿轮8为例），进而驱动限位板51移动，完成了自调节的过程中。
进一步的，所述连接杆3上开设有与空腔11相连通的穿孔41，牵引绳7的部分绳体位于穿孔41中，从而可以对牵引绳进行有效保护，延长其使用寿命。
总结来说，本实施例中，通过在支撑环4的内圈中设置沿周向等距布设的多个限位板51，由多个限位板51构成了用于防止儿童跌倒的限位空间，提高了使用的安全性，且利用移动组件进行限位板51的驱动，使得限位空间的大小能够进行调整，保证对于儿童的限位效果；通过设置由腿部套环6和驱动齿轮8构成的移动组件，在使用时，能够利用儿童对于腿部套环6的拽拉来带动限位板51移动，从而实现了自调节，使用起来更为方便灵活。
实施例2
请参阅图1和图4，本发明实施例在实施例1的基础上对行走机构进行了改进，具体来说：
传统的儿童助行器的行走机构均为滚轮，这样在需要儿童保持静止或者设备闲置时，整体易在外力作用下产生移动，为解决这一问题，本实施例中，所述行走机构包括安装架91；所述安装架91由中心体911和呈三角布设的分支体912构成，中心体911通过安装轴92与支撑体转动连接，其中一个所述分支体912上固定有支撑座94，另外两个所述分支体912上安装有滚轮93，在整体需要移动时，让两个滚轮93与地面接触，从而实现移动，而需要整体保持静止时，则可以转动支撑架91使得支撑座94与地面接触，避免整体在外力作用下移动。
进一步的，所述安装轴92的末端还固定有操作柄921，方便进行翻转操作。
进一步的，所述支撑座94上设置有防滑垫941，增强整体的防滑性能。
总结来说，本实施例中，通过设置由中心体911以及三个分支体912构成的安装架91，并将滚轮93和支撑座94分别安装在三个分支体912上，使得整体可以在移动模式和静止模式中进行切换，满足不同的使用需求，且操作起来简单快捷。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
