Abstract

本实用新型公开了一种密封型圆头螺栓,包括有上端面呈球面的螺栓头和螺杆,螺栓头上端面设有内六角凹槽,螺栓头下端面设有围绕螺杆的环槽,环槽内嵌装有密封橡胶圈。本实用新型结构简单,设计合理,采用在螺栓头下端面设置密封橡胶圈的设计,使得圆头螺栓安装后具有密封功能,可以使圆头螺栓运用到对于密封性要求较高的机器中,扩大了其使用范围。

Description

一种密封型圆头螺栓
技术领域
本实用新型涉及螺栓领域,具体为一种密封型圆头螺栓。 
背景技术
螺栓是最常见的紧固件之一,它由头部和螺杆组成。螺杆呈圆柱状,上带有外螺纹可与螺母搭配使用。螺栓和螺母共同使用,可连接和固定两个带有通孔的部件。螺栓按头部形状可分为六角头螺栓、圆头螺栓、方形头螺栓、沉头螺栓等等。而现有技术中的圆头螺栓功能比较单一,不具备密封的性能,因此不适用于对密封性要求较高的机器中。 
实用新型内容
本实用新型的目的是提供一种密封型圆头螺栓,以解决现有技术中传统的圆头螺栓功能比较单一,不具备密封的性能,因此不适用于对密封性要求较高的机器中的问题。 
为达到上述目的,本实用新型采用的技术方案为: 
一种密封型圆头螺栓,其特征在于:包括有上端面呈球面的螺栓头和螺杆,所述螺栓头上端面设有内六角凹槽,所述螺栓头下端面设有围绕螺杆的环槽,所述环槽内嵌装有密封橡胶圈。
所述的一种密封型圆头螺栓,其特征在于:所述密封橡胶圈略凸出于螺栓头的下端面。 
本实用新型的有益效果为: 
本实用新型结构简单,设计合理,采用在螺栓头下端面设置密封橡胶圈的设计,使得圆头螺栓安装后具有密封功能,可以使圆头螺栓运用到对于密封性要求较高的机器中,扩大了其使用范围。
附图说明
图1为本实用新型的剖视图。 
具体实施方式
如图1所示,一种密封型圆头螺栓,包括有上端面呈球面的螺栓头1和螺杆2,螺栓头1上端面设有内六角凹槽3,螺栓头1下端面设有围绕螺杆2的环槽4,环槽4内嵌装有密封橡胶圈5。密封橡胶圈5略凸出于螺栓头1的下端面。
