Abstract

本实用新型涉及一种改进型塑胶单轮脚轮架，包括安装于手推货车底部的轴承座板，所述轴承座板下有一可绕其纵向轴心线旋转360度的脚轮支架及脚轮，所述脚轮支架两侧设有一对用以支撑脚轮的拐臂，其特征在于：所述拐臂上方设有一对延伸臂，所述延伸臂内铰接有一翘板，所述翘板内侧端设有向上穿过轴承座板中心通孔的中控线和用于卡住轴承座板底侧环形齿盘的凸齿，脚轮支架与翘板之间设有以使翘板复位的复位弹簧组件。本实用新型使用方便，结构简单，整体采用塑胶构件，注塑成型简单，可大规模生产，故成本低廉，有效克服了传统脚轮制动的缺陷，更有利于用户接受。

Description

改进型塑胶单轮脚轮架
技术领域
本实用新型涉及一种改进型塑胶单轮脚轮架。
背景技术
现有的手推货车脚轮只能以脚踩刹制动，这样显然不利于推车用户的使用。
发明内容
本实用新型的目的是要提供一种改进型塑胶单轮脚轮架，采用该脚轮架制造的手推货车，有利于用户在推动手推货车时的制动控制。
本实用新型是这样构成的：包括安装于手推货车底部的轴承座板，所述轴承座板下有一可绕其纵向轴心线旋转360度的脚轮支架及脚轮，所述脚轮支架两侧设有一对用以支撑脚轮的拐臂，其特征在于：所述拐臂上方设有一对延伸臂，所述延伸臂内铰接有一翘板，所述翘板内侧端设有向上穿过轴承座板中心通孔的中控线和用于卡住轴承座板底侧环形齿盘的凸齿，脚轮支架与翘板之间设有以使翘板复位的复位弹簧组件。
本实用新型由于一方面可通过向上提升中控线使翘板外侧部的制动块卡住脚轮防止其滚动；另一方面，翘板内侧上端的凸齿向上顶住轴承座板底侧的环形齿，使脚轮及其支架无法相对轴承座板转动。因此，该装置安装在手推货车后，可实现手推货车的有效控制定位。
附图说明
图1是本实用新型脚轮架的主视图。
图2是本实用新型脚轮架的左视图。
图3是本实用新型脚轮架的局部剖视图。
具体实施方式
本实用新型是这样构成的：包括安装于手推货车底部的轴承座板1，所述轴承座板下有一可绕其纵向轴心线旋转360度的脚轮支架2及脚轮3，所述脚轮支架两侧设有一对用以支撑脚轮的拐臂4，其特征在于：所述拐臂上方设有一对延伸臂5，所述延伸臂内铰接有一翘板6，所述翘板内侧端设有向上穿过轴承座板中心通孔的中控线7和用于卡住环形齿盘8的凸齿9，脚轮支架与翘板之间设有复位弹簧组件，所述复位弹簧组件为联接于翘板内侧上部与脚轮支架顶部之间的复位簧片10，所述翘板外侧部下方设有以利卡住脚轮上侧部的制动块11，所述部件由塑胶制成。
本实用新型的工作过程是：手刹制动时，向上提升中控线7，中控线使翘板6外侧部的制动块11卡住脚轮3防止其滚动，翘板内侧上端的凸齿9向上顶住轴承座板1底侧的环形齿8，使脚轮及其支架2无法相对轴承座板转动。
本实用新型使用方便，结构简单，整体采用塑胶构件，注塑成型简单，可大规模生产，故成本低廉，有效克服了传统脚轮制动的缺陷，更有利于用户接受。
