一种高夹紧防松法兰面螺栓
[0001]本技术涉及一种高夹紧防松法兰面螺栓。
技术介绍
[0002]螺栓,机械零件,配用螺母的圆柱形带螺纹的紧固件。由头部和螺杆两部分组成的一类紧固件,需与螺母配合,用于紧固连接两个带有通孔的零件。这种连接形式称螺栓连接。
[0003]目前,市场上的法兰面螺栓,它包括螺栓头部以及与螺栓头部连接的杆体,在对紧固件进行固定后,长时间可能会出现一定程度的松动,对一些稳定性要求较高的紧固件来讲可能会造成一定的影响,并且传统的螺栓的螺栓头和螺栓杆为固定式的连接,不可拆卸,无法更换螺栓头,需要借助不同的特定旋紧工具来对不同形状的螺栓头进行旋紧。由此有必要作出改进。
技术实现思路
[0004]本技术旨在解决现有技术中存在的技术问题之一。
[0005]本申请提供了一种高夹紧防松法兰面螺栓,其特征在于,包括:
[0006]螺柱,其顶部固定安装有横向截面呈多边形的卡接块;
[0007]螺头,其带有用于供卡接块卡接的卡孔;
[0008]固定机构,其用于使卡接块与卡孔固定连接;
[0009]垫片,其带有通孔且套设在所述卡接块外侧;
[0010]其中,所述垫片位于所述螺柱与螺头之间。
[0011]采用上述的一种高夹紧防松法兰面螺栓,将所需形状的螺头通过卡孔与卡接块的配合安装到螺柱一端,通过固定机构对卡孔和卡接块之间进行固定连接,使螺头不会脱落,工人通过与螺头外形相适配的工具扭动螺头,通过呈多边形的卡块和卡孔的配合将扭力传递到螺柱中,使 ...
