Description

设有透明压紧盖板的警示功能扭矩扳手
技术领域
本发明涉及一种扳手,具体地说是一种设有透明压紧盖板的警示功能扭矩扳手。
背景技术
目前,扳手在使用过程中往往会因为用力过猛导致螺栓头拧断的情况发生,现有带警示功能的扳手多为电子警示装置,这种扳手价格相对昂贵。
本发明的目的是提供一种设有透明压紧盖板的警示功能扭矩扳手。
本发明要解决现有技术存在的扳手在使用过程中往往会因为用力过猛导致螺栓头拧断的情况发生,现有带警示功能的扳手价格相对昂贵问题。
发明内容
本发明的技术方案是: 一种设有透明压紧盖板的警示功能扭矩扳手,包括扳手本体,所述的扳手一端为梅花扳手头,所述的梅花扳手头包括一安装孔和容置腔,所述的安装孔内设有扭力圈,所述的扭力圈下部设有顶块,所述的顶块置于容置腔一侧,所述的容置腔另一侧设有弹簧,所述的弹簧一端顶于顶块上,另一端顶于容置腔的内壁面上;所述的顶块后端部与扭力圈相交的位置的扭力圈上设有指示箭头;所述的梅花扳手头外部设有压紧盖板;所述的压紧盖板与梅花扳手头采用螺丝连接,所述的压紧盖板为透明材料制成。
所述的扭力圈在安装孔内可相对转动,所述的扭力圈与顶块为一体成型结构。
所述的安装孔和容置腔连通,所述的连通的位置右侧为档点,所述的容置腔为“﹄”结构,所述的“﹄”结构上部具有一定长度。
所述的档点到容置腔右侧的内壁面的距离大于或等于弹簧最大压缩的距离,从而防止弹簧被过度压缩而失效。
所述的扭力圈内壁为配合螺栓头的多边形啮合口。
本发明的有益效果为:本发明结构简单,能起到警示功能,使用方便,且成本低;内部设有档点,有效防止零件过载,同时避免本发明的弹簧压缩过度,导致弹簧失效。
附图说明
图1是本发明的结构示意图。
图2是本发明梅花扳手头的结构示意图。
图3是图2拿掉扭力圈的结构示意图。
图4是本发明容置腔的距离结构示意图。
图5是本发明施力后弹簧的压缩结构示意图1。
图6是本发明施力后弹簧的压缩结构示意图2。
具体实施方式
下面结合附图及实施例对本发明作进一步说明。
如图所示,本发明包括扳手本体1,所述的扳手1一端为梅花扳手头8,所述的梅花扳手头8包括一安装孔6和容置腔12,所述的安装孔6内设有扭力圈7,所述的扭力圈7下部设有顶块10,所述的顶块10置于容置腔12一侧,所述的容置腔12另一侧设有弹簧9,所述的弹簧9一端顶于顶块10上,另一端顶于容置腔12的内壁面上,所述的压紧盖板为透明材料制成。
所述的扭力圈7在安装孔6内可相对转动,所述的扭力圈7与顶块10为一体成型结构。
所述的安装孔6和容置腔12连通,所述的连通的位置右侧为档点11,所述的容置腔12为“﹄”结构,所述的“﹄”结构上部具有一定长度S1。
所述的档点11到容置腔12右侧的内壁面的距离S大于或等于弹簧12最大压缩的距离,从而防止弹簧12被过度压缩而失效。弹簧到达最大压缩后,由于档点11的作用,顶块10不再位移,从而防止弹簧12被过度压缩而失效。
所述的梅花扳手头外部设有压紧盖板2。
所述的压紧盖板2与梅花扳手头采用螺丝4连接。
所述的扭力圈7内壁为配合螺栓头的多边形啮合口。该扭力圈7内壁的多边形结构与普通的扳手内壁结构一样。
本发明专利根据螺栓的规格,专门螺栓佩专门的等级、扭矩的扳手,例如为螺栓规格为M10*1.5P,螺栓等级为8.8级的,最小破坏扭矩设为66N.m,当该梅花扳手头套于螺栓上进行施力的时候,由于力的作用是相互,当对扳手从右往左施力时候,螺栓会给扭力圈从左往右的力,从而带动扭力圈从左往右旋转,扭力圈的旋转带动顶块旋转,从而顶块将弹簧压缩,当对扳手的力逐渐增大时,顶块对将弹簧压缩越大,其扭力圈的旋转位移越大,指示箭头将不断从左往右移动,由于压紧盖板为透明材料制成,可以时时看到弹簧压缩的状态,箭头位置移动从可施力范围指示区域移动到不可施力范围指示区域时候,就要停止用力,如果继续用力,箭头位置将移动到极限范围指示区域,此时,可能会破坏螺栓扭矩,由于本发明设置了档点,所以本发明尽管不管施加外力,当顶块顶于档点后,其顶块就不会发生位移,由于设有档点,所以本发明防止了弹簧被过度压缩而失效。
由于压紧盖板为透明材料制成,可以时时看到弹簧压缩的状态,从而防止破坏螺栓扭矩。
