Description

一种带垫圈的六角螺帽结构
技术领域
本发明涉及螺帽技术领域，具体为一种带垫圈的六角螺帽结构。
背景技术
螺帽是与螺丝、螺栓，螺钉相到配合的使用，起连接紧固机件作用的零部件，六角螺帽是常见的，如图1所示，其通过手拧或者扳手来实现拧紧或者旋松，由于螺帽可能要频繁拆卸，与螺丝螺栓等接触面容易出现磨损，减少使用寿命。
发明内容
为了解决上述问题，本发明提供了一种带垫圈的六角螺帽结构，其能够有效减少磨损，延长使用寿命。
其技术方案是这样的：一种带垫圈的六角螺帽结构，其包括本体，其特征在于，所述本体上开有台阶孔，所述台阶孔的小径部分内壁设置内螺纹，所述台阶孔的大径部分内壁为光滑面，所述台阶孔开口处设置有防磨垫圈，所述防磨垫圈为弹性部件，所述台阶孔大径部分内壁下端开有环形卡槽，所述防磨垫圈下端外周面设置有与所述环形卡槽配合的卡块，所述防磨垫圈上端外周面为环形卡圈结构，所述本体外周面上开有与所述环形卡圈结构配合的环形凹槽，所述防磨垫圈上开有尺寸大于所述台阶孔小径部分的通孔。
其进一步特征在于，所述台阶孔开口处上表面环形台阶为粗糙面。
采用本发明的结构后，由于在本体上安装了防磨垫圈，在使用过程中只磨损防磨垫圈，本体基本不受影响，防磨垫圈损坏后只需要更换一个新的即可，不用更换六角螺帽本体，环形卡槽与卡块的配合、环形凹槽与环形卡圈结构的配合保证了防磨垫圈不会自动脱落，由于是弹性部件，拆卸起来也比较方便，延长了六角螺帽本体的使用寿命。
附图说明
图1为现有的螺帽结构俯视图；
图2为本发明螺帽剖面示意图。
具体实施方式
见图2所示，一种带垫圈的六角螺帽结构，其包括本体1，本体1上开有台阶孔2，台阶孔2的小径部分内壁设置内螺纹3，台阶孔2的大径部分内壁为光滑面，台阶孔2开口处设置有防磨垫圈4，防磨垫圈4为弹性部件，台阶孔2大径部分内壁下端开有环形卡槽5，防磨垫圈4下端外周面设置有与环形卡槽5配合的卡块6，防磨垫圈4上端外周面为环形卡圈结构7，本体1外周面上开有与环形卡圈结构7配合的环形凹槽8，防磨垫圈4上开有尺寸大于台阶孔2小径部分的通孔10。台阶孔2开口处上表面环形台阶为粗糙面9，保证了防磨垫圈4与本体1之间的接触，进一步确保不容易脱落。
