Abstract

本实用新型涉及一种操作阀门的手轮,包括轮圈及置于其中向心均匀分布的若干条辐条,轮圈和辐条为一体式钢板冲制薄壁结构,轮圈的最外圈边缘设有向内延伸的翻边。在轮圈外边缘的翻边不影响整体结构重量,可以大大提高整个轮圈的强度,碰撞也不容易变形,而且操作手感强,用力快速操作方便,不会割手,提高使用安全性。

Description

阀门手轮
技术领域:本实用新型涉及一种操纵阀门用的手轮。
背景技术:一般的阀门手轮较多为铸造式,强度不高,表面不够光滑。现在有了钢板冲制的一体式手轮,重量轻,表面光滑,结构强度也较高,但钢板冲制的手轮都是薄壁结构,轮圈的边缘在碰撞时很容易凹陷而变形,而且直切边的外边缘手握操作性较差,可能会割破手,用力快速操作时不方便。
发明内容:针对现有技术的不足,本实用新型提供一种轮圈边缘强度高,操作性好的阀门手轮。
本实用新型包括轮圈及置于其中向心均匀分布的若干条辐条,轮圈和辐条为一体式钢板冲制薄壁结构,轮圈的最外圈边缘设有向内延伸的翻边。
在轮圈外边缘的翻边不影响整体结构重量,可以大大提高整个轮圈的强度,碰撞也不容易变形,而且操作手感强,用力快速操作方便,不会割手,提高使用安全性。
下面结合附图和实施例进一步说明本实用新型。
附图说明:图1是实施例的主视图;
          图2是图1的A-A剖面放大图;
          图3是图1的B-B剖面放大图。
实施例:如图所示,轮圈1中向心均匀分布有若干条辐条2,轮圈1和辐条2为一体式钢板冲制薄壁结构,轮圈1的最外圈边缘设有向内延伸的翻边3。在实际使用时,轮圈1的结构强度很高,在每一辐条2的上面设有沿辐条方向的凹槽4构成加强筋结构,这样辐条2的结构强度也提高,并且可以装饰。

Claims (2)
