Abstract

本实用新型特指一种轮椅背靠的转动调节机构。包括有背靠架、设置在背靠架后方的拉杆和调节卡板，在拉杆上设有限位块，在该限位块的上方设置有安装在背靠架上的限位台，拉杆活动穿过限位台，在拉杆上限位块和限位台之间套装有复位弹簧；调节卡板的上端的左侧与拉杆的下端铰接，而右侧与背靠架成铰接，且其朝背靠架的一侧成型有导向槽孔，该导向槽孔的上侧成型有多个级进齿，且孔内活动设置有与级进齿配合的销钉，该销钉固装在背靠架上。采用上述技术方案后，整个轮椅背靠调节机构的零部件少、结构变得简单，使制造的成本大大降低。

Description

轮椅背靠的转动调节机构
技术领域：
本实用新型涉及轮椅技术领域，特指一种轮椅背靠的转动调节机构。
背景技术：
目前医疗康复用的轮椅的背靠转动调节机构由于其结构复杂，零部件多，导致轮椅的制造成本非常高。
发明内容：
本实用新型的目的是为了解决上述现有技术的缺点，提供一种结构简单、成本低廉的轮椅背靠转动调节机构。
为实现上述目的，本实用新型提供的技术方案为：轮椅背靠的调节机构，包括有背靠架、设置在背靠架后方的拉杆和调节卡板，在拉杆上设有限位块，在该限位块的上方设置有安装在背靠架上的限位台，拉杆活动穿过限位台，在拉杆上限位块和限位台之间套装有复位弹簧；调节卡板的上端的左侧与拉杆的下端铰接，而右侧与背靠架成铰接，且其朝背靠架的一侧成型有导向槽孔，该导向槽孔的上侧成型有多个级进齿，且孔内活动设置有与级进齿配合的销钉，该销钉固装在背靠架上。
采用上述技术方案后，整个轮椅背靠调节机构的零部件少、结构变得简单，使制造的成本大大降低。
附图说明：
图1是本实用新型的轮椅的背靠架没有调节时的结构示意图；
图2是本实用新型的轮椅的背靠架调节到一定角度后的结构示意图。
具体实施方式：
现结合附图详细阐述本实用新型：
如附图1～附图2所示的轮椅背靠的调节机构包括有背靠架1、设置在背靠架1后方的拉杆2和调节卡板3，在拉杆2上一体成型有圆球形限位块4，在该圆球形限位块4的上方设置有安装在背靠架1上的限位台5，拉杆2活动穿过限位台5，在拉杆2上圆球形限位块4和限位台5之间套装有复位弹簧6；调节卡板3的上端的左侧与拉杆2的下端铰接，而右侧与背靠架1成铰接，且其朝背靠架1的一侧成型有导向槽孔7，该导向槽孔7的上侧成型有多个级进齿8，且孔内活动设置有与级进齿8配合的销钉9，该销钉9固装在背靠架1上。
需要调节轮椅的背靠架1时，拉动拉杆2，复位弹簧6受压收缩，调节卡板3被拉起，卡在级进齿8内的销钉9滑进导向槽孔7，这时，操作人员就可以转动背靠架1到适当的角度，松开拉杆2，在复位弹簧6的作用下，销钉9会滑进相应的级进齿8内。
