本实用新型所要解决的技术问题是提供一种结构合理、方便调节的儿童安全座椅支撑腿档位调节机构。
本实用新型解决上述技术问题所采用的技术方案为：
一种儿童安全座椅支撑腿档位调节机构，包括外管和内管，所述内管可滑动设置在所述外管内，所述外管的一侧固定安装有第一盖体，所述第一盖体与所述外管之间具有容纳腔，所述外管上设有定位孔，所述内管沿其长度方向排列有多个档位孔，所述容纳腔内设有档位调节销，所述第一盖体上设有按动开关，所述按动开关通过滑移安装于所述容纳腔内的联动件使所述档位调节销穿过定位孔和档位孔，进而锁定所述外管和内管的位置，或者使所述档位调节销脱离所述档位孔解除所述外管和所述内管的锁定。
作为优选，所述联动件的侧面包括第一斜面和第二斜面，所述第一斜面与所述第二斜面的倾斜方向相同，所述联动件于所述第二斜面上设有贯穿所述联动件的第一滑槽，所述档位调节销部分插装在所述第一滑槽内，并能够沿所述第二斜面移动，所述按动开关的底部抵于所述第一斜面，当挤压所述按动开关时，所述联动件在第一斜面的作用下沿所述外管的长度方向移动，所述档位调节销在所述第二斜面的驱动下脱离所述档位孔。
作为优选，所述容纳腔内设有驱使所述联动件及所述按动开关复位的第一弹性件。
作为优选，所述第一弹性件为压缩弹簧或者拉簧。
作为优选，所述容纳腔内还设有驱使所述档位调节销向着所述档位孔运动的第二弹性件。
作为优选，所述联动件朝向所述第一盖体的侧面还包括第一平面，所述第一平面的两端分别对应连接所述第一斜面较低的一端和所述第二斜面较低的一端，并且所述第一滑槽延伸至所述第一平面内，当所述档位调节销插装在所述档位孔内时，所述档位调节销滑动至第一滑槽位于所述第一平面内的一端。
作为优选，所述档位调节销包括限位销轴和位于限位销轴外侧沿径向延伸的限位块，所述限位销轴插装在所述第一滑槽内，并使所述 限位块卡于联动件上第一滑槽的两侧边沿。

具体实施方式
以下结合附图实施例对本实用新型作进一步详细描述。
一种儿童安全座椅支撑腿档位调节机构，结合图1-9所示，包括外管1和内管2，内管2可滑动设置在外管1内，外管1的一侧固定安装有第一盖体3，第一盖体3与外管1之间具有容纳腔31，外管1上设有与容纳腔31连通的定位孔11，内管2沿其长度方向排列有多个档位孔21，容纳腔31内设有档位调节销4，第一盖体3上设有按动开关5，按动开关5通过滑移安装于容纳腔31内的联动件6使档位调节销4穿过定位孔11和档位孔21，进而锁定外管1和内管2的位置，或者使档位调节销4脱离档位孔21解除外管1和内管2的锁定。其中,外管1的外侧还设有第二盖体9，第一盖体3和第二盖体9扣合，将外管1包裹在内,而扣合的第一盖体3和第二盖体9作为一个整体与儿童安全座椅连接。
具体地，第一盖体3上开设有与容纳腔31连通的安装孔35，按动开关5设于安装孔35内，按动开关5的侧面设有卡于安装孔35背侧边沿的限位凸起51，用于防止按动开关5脱离安装孔35。
外管1朝向第一盖体3的侧面凹陷形成沿外管1的长度方向延伸的第一导向槽12，相应的内管2朝向第一盖体3的侧面也凹陷形成有与第一导向槽12对应叠合的第二导向槽22，可以确保内管2只沿外管1长度方向移动,从而保证定位孔11能够和档位孔21对位供档位调节销4插入锁定。第一盖体3设有插装至第一导向槽12内的第一限位板33和第二限位板34，从而在第一导向槽12内形成用于供上述联动件6安装的容纳腔31，其中联动件6及定位孔11均位于第一限位板33和第二限位板34之间，而多个档位孔21间隔排布于第二导向槽22内。
联动件6朝向第一盖体3的侧面包括第一斜面61和第二斜面62，第一斜面61与第二斜面62的倾斜方向相反，即第一斜面61较低的一端与第二斜面62较低的一端相向设置或者背向设置，联动件6于第二斜面62上设有贯穿联动件6的第一滑槽66，档位调节销4部分插装在第一滑槽66内，并能够沿第二斜面62移动，按动开关5的底部抵于第一斜面61，当挤压按动开关5时，联动件6在第一斜面61的作用下沿第一滑槽66移动，档位调节销4在第二斜面62的驱动下脱离档位孔21。
本具体实施例中，联动件6朝向第一盖体3的侧面还包括第一平面63、第二平面64和第三平面65，第一平面63的两端分别对应连接第一斜面61较低的一端和第二斜面62较低的一端，并且第一滑槽66延伸至第一平面63内，当档位调节销4插装在档位孔21内时，档位调节销4滑动至第一滑槽66位于第一平面63内的一端。而第二平面64与第一斜面61较高的一端连接，使运动开关的限位凸起51位于第一盖体3和第二平面64之间，第二平面64上还设有容纳槽641，按动开关5向下运动时，限位凸起51能够容置于容纳槽641内。而第三平面65与第二斜面62较高的一端连接，并且第三平面65始终抵于第一盖体3，从而使联动件6只能沿第一导向槽12移动。为了使按动开关5可以正常工作，锁定状态时，按动开关5与第一平面63之间留有空隙，并且按动开关5上还设有与第一斜面61相对应的第四斜面52。
容纳腔31内设有驱使联动件6及所述按动开关5复位的第一弹性件7，第一复位件可以是压缩弹簧，压缩弹簧的一端抵于第一限位板33，另一端抵于联动件6。第一弹性件7也可以是拉簧，拉簧的一端与第二限位板34连接，拉簧的另一端与联动件6连接。
档位调节销4包括限位销轴41和位于限位销轴41外侧沿径向延伸的限位块42，限位销轴41插装在第一滑槽66内，并使限位块42卡于联动件6上第一滑槽66的两侧边沿。其中，容纳腔31内还设有驱使档位调节销4向着档位孔21运动的第二弹性件8。
具体地，第一盖体3于容纳腔31内设有与档位调节销4同向延伸，用于限制档位调节销4位置的限位件32，本具体实施例中，档位销轴41的截面为矩形，档位销轴41的宽度两侧设有限位件32，第二弹性件8为压缩弹簧，压缩弹簧套设在两个限位件32外侧，压缩弹簧远离第一盖体3的一端抵于限位块42，进而驱使档位调节销4向档位孔21运动，并且限位块42于压缩弹簧的外侧延伸有限位凸块421，限制压缩弹簧始终保持抵于限位块42。
与现有技术相比，本实用新型的儿童安全座椅支撑腿档位调节机构的优点在于，使用时通过按压按动开关5，按动开关5会推动联动件6的第一斜面61，使联动件6沿外管1的第一滑槽66移动，并使作为第一弹性件7的压缩弹簧受力压缩，而档位调节销4由于插装在定位孔11和档位孔21内，其相对于外管1和内管2的位置不动，第二斜面62作用在档位调节销4的限位块42上，档位调节销4只能沿第二斜面62向上运动直至脱离内管2，从而解除外管1和内管2之间的锁定，此时拉动或者推动内管2来调节支撑腿的长度，操作简单、方便。而当支撑腿的长度调节完成后，松开按动开关5，联动件6会在压缩弹簧的推动下回到初始状态，此时档位调节销4也在第二复位件的作用下向内管2运动，并插装在档位孔21内，从而再次实现内管2和外管1的锁定，完成支撑腿长度的调节并锁住。在操作时，可以实现单手释锁，支撑腿一键落地的效果，操作更为方便快捷，双斜面结构更加稳 定。
尽管以上详细地描述了本实用新型的优选实施例，但是应该清楚地理解，对于本领域的技术人员来说，本实用新型可以有各种更改和变化。凡在本实用新型的精神和原则之内所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
