具体实施方式
以下结合附图对本发明做进一步的说明。
从图 1所示的可调节婴儿高椅的结构可以看出，高椅主要包括支 脚部分 2和座椅部分 1。 座椅部分 1 .由座位 11、 靠背 12、 餐盘 13、 盘子 14和玩具 15构成， 餐盘 13、 盘子 14和玩具 15安装在座位 11 的前方， 靠背 12下端通过转轴 16与座位 11连接， 与座位 11两側的 扶手 17形成包围式结构， 保证了婴儿坐在其中的安全性。 支脚部分 2包括 U形底座 21，安装在 U形底座 21中部倾斜支撑杆 22和支撑杆 22上端的竖直套管 23构成， 这种结构即节省材料又保证了结构的稳 定性。 且 U形底座 21的两侧末部设有滚轮 24， 中部设有防滑垫 25， 有利于高椅的移动和定位。 ― 上述餐盘 13通过前后调节机构 3安装在座位 11前方，座椅部分 1通过高度调节机构 5和转向调节机构 6与支脚部分 2连接，靠背 12 通过倾斜调节机构 4与座位 11连接。本发明设有多个可调节的机构， 使得高椅的尺寸和规格可以进行人性化的调节，适用不同人群和环境 使用， 具体的调节过程如下述。
餐盘 13的前后调节机构 3的具体结构结合图 1、 图 2所示， 包 括安装在餐盘 13两内侧的调节按钮 31、 调节扣 32和压迫调节扣 2 前端向内转动的扭簧 33。 调节按钮 31的前端与调节扣 32的后端配 合 ,座位 11两侧扶手 17上设有多个与调节扣 32前端配合的卡座 171。 在按下调节按钮 31时能够压迫调节扣 32的后端，使其前端赵起， 与 卡座 171脱离， 如图 2中箭头所示， 便可以前后滑动餐盘 13。 移动 至合适的位置上松开调节按钮 31 , 调节扣 32前端在扭簧 33的作用 下与卡座 171再次配合， 从而实现定位。 餐盘 13的前后调节可以调 节座位 11的空间大小， 以便于适用不同年龄的婴儿。
高椅的高度调节结合图 3和图 4所示，所述高度调节 勾 6包括 分别与座椅部分 1连接的内套管 61和与支脚部分连接外套管 62，内、 外套管 61、 62相对嵌套且可以相对滑动， 定位旋钮 63 穿过外套管 62与内套管 61配合定位。松开定位旋钮 63即可松开内、外套管 61、 62 , 使其可以相对滑动， 如图中箭头所示， 降低后的高度如图 4所。 倾斜调节机构 的具体结构如图 6所示， 包括一门形靠背支撑 42、 复位弹簧 43和按手 41。 靠背支撑 42的部分横梁、 复位弹簧 43 和按手 41安装在靠背 12背面的壳体中，复位弹簧 43和按手 41相对 分别位于横梁上下侧。 靠背支撑 42可相对壳体上下滑动， 靠背 12背 面设有靠背支撑 42两侧调节杆的定向环 121 , 座位 11两侧扶手 17 上设有多个与调节杆配合的定位孔 172。 为了婴儿坐得更舒服可以调 节靠背 . 12的倾斜度， 如图 5所示， 按下按手 41升高靠背支撑 42两 侧调节杆脱离定位孔 172， 即可松开靠背 12与座位 11的锁定。 使得 靠背 12绕转轴 16转动， 如图 7所示， 直至合适的位置。 松开按手 41 , 复位弹簧 43使调节杆再次插入定位孔 172 , 即可实现靠背 12与 座位 11的锁定。
座椅部分 1的转向调节如图 8中箭头所示，座椅 1可以来回转动 以适用不同摆放位置的需要，座椅部分 1在相对支脚部分 2转动过程 可以实现自锁定。转向调节机构 5如图 9所示， 包括固定在座椅部分 1下部的转轴 51 , 依次嵌套在转轴 51上的压缩弹簧 52和上齿轮 53 以及固定在转轴 51下端、 与上齿轮 53配合的下齿轮 54， 上述机构 安装在座椅部分 1下侧的套管中。 在本实施例中， 下齿轮 54通过六 角螺母 55固定在转轴 51的下端，在转轴 51的外侧压缩弹簧 52的上 端套接有胶套 56， 胶套 56与转轴 51之间设有轴承 57。 座椅部分 1 的转动带动转轴 51和其下端的下齿轮 54转动， 下齿轮 54的转动推 动上齿轮 53向上运动和压缩弹簧 52压缩， 每转过一个齿， 上、 下齿 轮 53、 54在压缩弹簧 52的推动下实现定位。这种自锁定机构在转动 的推力不大于压缩弹簧 52的弹力时能够实现锁定, 当大于压缩弹簧 52的弹力时解锁转动。 座椅部分 1相对于支脚部分 2转动后的结构 可以如图 10所示。
综上所述本发明设有多种人性化的调节机构，可以使得婴儿高椅 的具有符合人体工程学的使用结构，本发明的保护结构并不局限于上 述实施例的结构，任何采用与本方案类似的可调节婴儿高椅均为本专 利所要求保护的范围。
