Description

销轴防转挡板
技术领域
本实用新型涉及一种随车起重机用配件,特别是涉及一种销轴防转挡板。 
背景技术
随车起重机等机械产品中,销轴连接应用较多,除了两端带挡圈的外,其它一般皆为固定销轴,工作中要求固定不转,这就需要对销轴作防旋转设计,现有技术中的防止销轴转动结构较为复杂,安装起来较繁琐,劳动强度较大。 
实用新型内容
本实用新型克服现有技术中的不足,提供一种结构简单、安装方便的销轴防转挡板。 
本实用新型的销轴防转挡板,包括轴端挡板和防转挡板,所述轴端挡板的中部设有用于与销轴配合的安装孔,所述轴端挡板的底边设V形凸起部,所述防转挡板的顶边开有V形槽且与所述轴端挡板的V形凸起部相匹配,所述轴端挡板的V形凸起部卡接在所述防转挡板的V形槽内限定所述销轴转动,这样通过端部V形凸起部与防转挡板的V形槽配合来限定销轴转动,结构简单,安装方便,可以有效降低劳动强度,提高效率。 
所述防转挡板为六边形结构,所述V形槽开在所述六边形的两条顶边上且以中心线对称设置,所述六边形的两条底边夹角为90度—150度,两条侧边夹角为0度—30度,两条顶边相对与V形槽槽边的夹角为60度—90度,这样防转挡板结构简单,可以由板材直接切割而成,加工简单快速。 
与现有技术相比本实用新型的有益效果为:由于在轴端挡板的底边设V形凸起部,防转挡板的顶边开有V形槽且与端部挡板的V形凸起部相匹配,轴端挡板的V形凸起部卡接在防转挡板的V形槽内限定销轴转动,这样通过端部V形凸起部与防转挡板的V形槽配合来限定销轴转动,结构简单,安装方便,可以有效降低劳动强度,提高效率。 
附图说明
图1是本实用新型中销轴防转挡板的结构示意图。 
图2是本实用新型中防转挡板的结构示意图。 
具体实施方式
下面结合附图和实施例,对本实用新型的具体实施方式作进一步详细描述。以下实施例用于说明本实用新型,但不用来限制本实用新型的范围。 
如图1和图2所示,一种销轴防转挡板,包括轴端挡板2和防转挡板3,轴端挡板2的中部设有用于与销轴1配合的安装孔,销轴1与轴端挡板2焊接,轴端挡板2的底边设V形凸起部,防转挡板3的顶边33开有V形槽且与轴端挡板2的V形凸起部相匹配,轴端挡板2的V形凸起部卡接在防转挡板3的V形槽内限定销轴1转动,防转挡板3为六边形结构,V形槽开在六边形的两条顶边33上且以中心线对称设置,六边形的两条底边31夹角b 范围为90≤b≤150,两条侧边32夹角a范围为0≤a≤30,两条顶边33相对与V形槽槽边的夹角c范围为60≤c≤90,防转挡板3结构简单,可以由板材直接切割而成,加工简单快速。 
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明技术原理的前提下,还可以做出若干改进和变型,这些改进和变型也应视为本发明的保护范围。
