技术领域
本发明涉及一种密封接头,具体讲是一种波纹管简易密封接头。
背景技术
波纹管密封结构其结构一般包括套接波纹管的接头组件,为了提高接头组件连接波纹管后的密封性,需要通过密封结构进行密封处理,而这类密封结构往往结构过于复杂。
发明内容
鉴于上述现有技术的缺陷,本发明的目的在于:提供一种波纹管简易密封接头。
本发明的技术解决方案是:波纹管简易密封接头,包括套接波纹管的接头组件,所述接头组件包括转接头,该转接头的后端具有从后至前依次分布的插管、斜台和螺纹部,斜台外壁上套有一与其形状相配的密封环,插管插入波纹管中,密封环压在波纹管端口内壁上,所述波纹管的端部外壁上套有由两个卡块拼接组成的卡环,转接头后端螺纹部上旋有一紧固套,紧固套压在卡块外壁上。
进一步地,所述密封环的内壁贴合在斜台的外壁上,密封环的外壁压在波纹管端口内壁上。
进一步地,所述卡块的内壁与波纹管外壁贴合。
进一步地,所述卡块的内壁上具有多个凹槽,波纹管端部外壁上具有与凹槽相配的凸圈,凸圈卡入凹槽中。
进一步地,所述卡块的前端具有外凸的弧形凸条,紧固套的后端具有向内延伸的凸环,凸环接触并抵住弧形凸条后端。
应用本发明所提供的波纹管简易密封接头,其有益效果是:通过套在斜台上的密封环与波纹管端口内壁紧密接触后,再通过紧固套压着由两个卡块拼接组成的卡环,使得卡环对波纹管施加压力并能够紧紧地压住波纹管,从而使得波纹管受压后能够更紧密地与密封环接触,密封效果更好。
附图说明
图1为本发明的整体结构示意图;
图2为本发明的分解示意图;
图3为本发明的剖视示意图;
图4为本发明卡块的结构示意图;
图5为本发明紧固套的结构示意图。
图中所述:1—波纹管,11—凸圈,2—转接头,21—插管,22—斜台,23—螺纹部,3—密封环,4—卡环,41—卡块,411—凹槽,412—弧形凸条,5—紧固套,51—凸环。
具体实施方式
为比较直观、完整地理解本发明的技术方案,现就结合本发明附图进行非限制性的特征说明如下:
如图1—图5所示,波纹管简易密封接头,包括套接波纹管1的接头组件,接头组件包括转接头2,该转接头2的后端具有从后至前依次分布的插管21、斜台22和螺纹部23,斜台22外壁上套有一与其形状相配的密封环3,插管21插入波纹管1中,密封环3压在波纹管1端口内壁上,波纹管1的端部外壁上套有由两个卡块41拼接组成的卡环4,转接头2后端螺纹部23上旋有一紧固套5,紧固套5压在卡块41外壁上。
卡环4由两个形状相同的卡块41拼接组成,这样方便将卡环4套在波纹管1外。
密封环3的内壁贴合在斜台22的外壁上,密封环3的外壁压在波纹管1端口内壁上,密封环3优选为金属环。
卡块41的内壁与波纹管1外壁贴合。为了卡块41内壁能紧密地贴合波纹管1外壁,卡块41的内壁上具有多个凹槽411,波纹管1端部外壁上具有与凹槽411相配的凸圈11,凸圈11卡入凹槽411中。
卡块41的前端具有外凸的弧形凸条412,紧固套5的后端具有向内延伸的凸环51,凸环51接触并抵住弧形凸条412后端。当紧固套5在与转接头2旋紧的过程中,紧固套5是向前移动的,所以紧固套5的凸环51能够给卡块41的弧形凸条412施加一个向前的推力,使得波纹管1也受到向前的推力后挤压密封环3,使波纹管1与密封环3接触地更为紧密。
本发明通过套在斜台22上的密封环3与波纹管1端口内壁紧密接触后,再通过紧固套5压着由两个卡块41拼接组成的卡环4,使得卡环4对波纹管1施加压力并能够紧紧地压住波纹管1,从而使得波纹管1受压后能够更紧密地与密封环3接触。
当然,以上仅为本发明的较佳实施例而已,非因此即局限本发明的专利范围,凡运用本发明说明书及图式内容所为之简易修饰及等效结构变化,均应同理包含于本发明的专利保护范围之内。
