Description

一种轮椅折背机构
技术领域
本发明涉及轮椅部件领域，尤其是一种轮椅折背机构。
背景技术
目前，轮椅生产制造好之后，在装箱时由于尺寸过大占据空间较大，给轮椅装箱带来诸多不便，增加了生产成本。
发明内容
为了克服现有轮椅装箱尺寸问题，降低生产成本，本发明提供了一种轮椅折背机构，能够减小轮椅装箱尺寸，降低生产成本。
为实现上述发明目的，本发明提出这样一种技术方案：一种轮椅折背机构，包括折背扳手1、上折背4和下折背7，所述的折背机构内部装有折背弹簧2和折背弹销10，折背弹簧2和折背弹销10中间配有垫圈3，上折背4和下折背7通过防松螺母6和十字头螺栓9与上背靠管5和下背靠管8紧固连接在一起。
本发明的有益效果是：使用本轮椅折背机构，能有效减小装箱尺寸，降低生产成本。本发明结构简单，易于制造。
附图说明
图1是轮椅折背机构的爆炸图。
图中，1，折背扳手；2，折背弹簧；3，垫圈；4，上折背；5，上背靠管；6，防松螺母；7，下折背；8，下背靠管；9，十字头螺栓；10，折背弹销。
具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细说明。
结合图1，以一种轮椅折背机构为例，轮椅用折背机构包括折背扳手1、上折背4和下折背7，所述的折背机构内部装有折背弹簧2和折背弹销10，折背弹簧2和折背弹销10中间配有垫圈3，上折背4和下折背7通过防松螺母6和十字头螺栓9与上背靠管5和下背靠管8紧固连接在一起。
按压折背扳手1时，在折背弹簧2弹力的作用下，折背弹销10能够前后缩进，此时上背靠管5就能够被折叠，这样便减少了轮椅的装箱尺寸，同样在拆箱时，挤压折背扳手1，上背靠管5能够被还原到原来的位置，操作简单。
