Abstract

本实用新型涉及一种动、静限位可调式关节。用于上肢肘关节和下肢膝关节的矫形器体积大,质量重,转动角度不可控,患者在康复期间无法控制矫形器的转动范围,影响康复效果。本实用新型在可调式关节的上关节盘和下关节盘之间设置上齿状角度盘和下齿状角度盘,四者通过连接轴销连接;上齿状角度盘和下齿状角度盘的侧边设置有齿条限位滑块机构;上齿状角度盘和下齿状角度盘上均设置有弧形调节槽;上关节盘上设置有限位销,位置与上齿状角度盘和下齿状角度盘上的弧形调节槽相对应。本实用新型体积小,重最轻,结构紧凑,使用方便,调整快捷,可在正负0~120度范围内,任意选择所需要设定的角度锁死,也可在正负0~120度范围内,任意选择所设定的自由转变角度。

Description

一种动、静限位可调式关节
技术领域
    本实用新型属于康复医学工程技术领域,具体涉及一种动、静限位可调式关节。
背景技术
目前,在假肢矫形器行业中,用于各种上肢肘关节和下肢膝关节的矫形器大多都体积大,质量重,所涉及的关节其角度均不可调控、固定的与自由转动的不能互换又不能限位。患者在康复期间无法自己控制矫形器角度的适用范围,影响患者的康复训练效果。
实用新型内容
本实用新型的目的是提供一种既能实现关节角度固定、又能实现规定范围内自由转动的动、静限位可调式关节。
本实用新型所采用的技术方案是:
一种动、静限位可调式关节,包含有上关节盘和下关节盘,其特征在于:
所述的上关节盘和下关节盘之间设置有上齿状角度盘和下齿状角度盘,四者通过连接轴销连接;
所述的上齿状角度盘和下齿状角度盘的侧边设置有齿条限位滑块机构。
所述的上齿状角度盘和下齿状角度盘上均设置有弧形调节槽。
所述的上关节盘上设置有限位销,位置与上齿状角度盘和下齿状角度盘上的弧形调节槽相对应。
所述的上关节盘或下关节盘表面设置有关节刻度面板。
    本实用新型具有以下优点:
本实用新型体积小,重最轻,结构紧凑,使用方便,调整快捷,可在正负0~120度范围内,任意选择所需要设定的角度锁死,也可在正负0~120度范围内,任意选择所设定的自由转变角度。
附图说明
图1为本实用新型结构图。
图2为A-A剖视图。
图中, 1-上关节盘,2-下关节盘,3-连接轴销, 4-上齿状角度盘, 5-下齿状角度盘,6-齿条限位滑块机构,7-关节刻度面板,8-限位销,9-角度盘拨动件,10-弧形调节槽。
具体实施方式
下面结合具体实施方式对本实用新型进行详细的说明。
本实用新型所述的一种动、静限位可调式关节,在上关节盘1和下关节盘2之间设置上齿状角度盘4和下齿状角度盘5,上关节盘1和下关节盘2为圆形,都设置有延伸件,用于与肘关节等的两节相连接;上齿状角度盘4和下齿状角度盘5也均为圆形,环周设置齿槽,;四者通过连接轴销3连接,均可以连接轴销3转动。上齿状角度盘4和下齿状角度盘5的侧边设置有齿条限位滑块机构6。上齿状角度盘4和下齿状角度盘5上均设置有弧形调节槽10,弧长与上关节盘1和之间的相对活动范围一致,如0-120度。下关节盘2上关节盘1上设置的限位销8,位置与上齿状角度盘4和下齿状角度盘5上的弧形调节槽10相对应,可对上齿状角度盘4和下齿状角度盘5起固定和限位作用。上关节盘1或下关节盘2表面设置有关节刻度面板7。上角度盘4和下角度盘5上都设置有角度盘拨动件9,用来转动上角度盘4和下角度盘5至适宜位置。
该关节可在正负0-120度范围内,任意选择所需要设定的角度锁死,也可在正负0-120度范围内,任意选择所设定的自由转变角度。既能实现关节角度的固定,也能实现规定范围内的自由转动。
该关节也可在0-120度范围内,任意选择所要设定的角度范围固定,也可在0-120度范围内,任意选择所设定的自由转动角度。
当开始设定某种角度时,首先需拨开限位滑块机构6,然后再分别将上角度盘4和下角度盘5上的指针对准关节刻度面板7上所需要的刻线角度值,最后再把限位滑块退回,卡住上角度盘4和下角度盘5即可。
