Abstract

本实用新型涉及一种喷雾器用防水塞杆,由螺母、密封圈、介指、唧同螺母、推杆及活塞所组成,其特征在于介指与唧同螺母之间设置了一个内环设置有若干条环形凸起的防水胶圈,并紧贴在推杆表面上,其密封性能及防水性能十分优越。

Description

一种喷雾器用防水塞杆
本实用新型涉及一种防水塞杆,尤其是一种喷雾器用防水塞杆。
现有的喷雾器用防水塞杆都是由螺母、密封圈、唧同螺母、推杆和活塞所组成,螺母和唧同螺母之间设置有一个塑料介指,密封圈设置在螺母与推杆之间。这种结构的塞杆主要靠介指及密封圈防水,使用时间长时,介指容易磨损,抽动推杆时,水会从螺母与推杆之间的缝隙里流出,因而其防水性能差。
本实用新型的目的在于针对上述存在的问题提供一种喷雾器用防水塞杆。
本实用新型是这样实现的:防水塞杆由螺母、密封圈、介指、唧同螺母、推杆和活塞所组成,其特征在于介指与唧同螺母之间增加一个防水胶圈,防水胶圈是环状的,其内环表面,即与推杆接触处表面设置有若干个环形凸起,并与推杆紧贴,因而其密封性能十分良好。
下面结合附图对本实用新型作进一步的描述。
图1是本实用新型的结构示意图。
图中,1是螺母,2是密封圈,3是介指,4是防水胶圈,5是唧同螺母,6是推杆,7是活塞。
本实用新型是喷雾器用的防水塞杆,由螺母1、密封圈2、介指3、唧同螺母5、推杆6和活塞7所组成,是喷雾器常用的组件,其特征在于介指3与唧同螺母5之间一个防水胶圈4,防水胶圈4是环形的,其内环表面设置有若干个环形凸起并紧贴住推杆7,因而其密封性能十分优越,防水性能好。

Claims (2)

1、一种喷雾器用防水塞杆,由螺母、密封圈、介指、唧同螺母、推杆及活塞所组成,其特征在于螺母与唧同螺母之间还设置有一个环状防水胶圈。
2、根据权利要求1所述的喷雾器用防水塞杆,其特征在于所述的防水胶圈其内环表面设置有若干个环形凸起,并与推杆紧密接触。
