背景技术
在管道连接过程中，相互连接的两个水管一般通过相应的水管接头来实现相互连接，且现有技术中存在形式各样的水管接头结构。
需进一步解释，在通过水管接头实现两个水管相互连接的过程中，水管接头必须保证连接处的密封性稳定以及锁紧可靠性。其中，对于硬质水管而言，水管接头只需正常扣压即可锁紧并保证密封性；而对于软质弹性水管而言，由于软质弹性水管的管壁具备一定的弹性，在水管接头连接时，必须通过强力扣压才能锁紧，但锁紧部位在长期强压的作用下会导致管壁破裂，特别是高温环境致使管壁变软会大量破裂漏水；故而，传统应用于硬质水管的水管接头不能适用于软质弹性水管。
针对上述情况，提供一种适合于软质弹性水管连接的水管接头就显得尤为重要。

水管卡持头的小直径段的外圆周壁设置有径向朝外凸出且呈圆环状的卡持凸起，卡持凸起的顶端的外径值较接头主体的小直径孔的直径值大。
其中，所述进水管头的外圆周壁与所述接头主体的大直径孔的内壁之间分别卡装有密封胶圈。
其中，所述接头主体的护套套装部外围螺装有外层管套，外层管套的中心孔的内壁设置有第一锥形面，接头主体的护套套装部前端部对应第一锥形面设置有第二锥形面。

具体实施方式
下面结合具体的实施方式来对本实用新型进行说明。
实施例一，如图1所示，一种结构改良的软质弹性水管接头，包括有接头主体1，接头主体1的后端部开设有朝后开口的大直径孔11，接头主体1的前端部开设有朝前开口且与大直径孔11同轴布置的小直径孔12，小直径孔12的后端部与大直径孔11连通，大直径孔11 的直径值较小直径孔12的直径值大，接头主体1的后端部设置有护套套装部14。
进一步的，接头主体1配装有水管卡持头2、位于水管卡持头2后端侧的进水管头3，水管卡持头2包括有一体成型的大直径段21以及位于大直径段21前端部且朝前凸出延伸的小直径段22，水管卡持头2的大直径段21的外径值分别较小直径段22的外径值、接头主体1的小直径孔12的直径值大，水管卡持头2的小直径段22前端部嵌插于接头主体1的小直径孔12内，水管卡持头2的芯部开设有前后完全贯穿的卡持头通孔23，进水管头3的芯部开设有前后完全贯穿的管头通孔31，进水管头3嵌插于接头主体1的大直径孔11内且进水管头3的外圆周壁与大直径孔11的内圆周壁螺接，进水管头3的前端面与水管卡持头2的大直径段21的后端面抵接。
更进一步的，水管卡持头2的小直径段22的外圆周壁设置有径向朝外凸出且呈圆环状的卡持凸起24，卡持凸起24的顶端的外径值较接头主体1的小直径孔12的直径值大。
在本实施例一的结构改良的软质弹性水管接头连接软质弹性水管的过程中，软质弹性水管的一端部依次穿过接头主体1的小直径孔12、大直径孔11并套入至水管卡持头2的小直径段22，而后将水管卡持头2、进水管头3依次插入至接头主体1的大直径孔11内，在此过程中，旋紧进水管头3，在进水管头3的推压作用下，水管卡持头2的大直径段21卡装于接头主体1的大直径孔11内，且水管卡持头2的小直径段22伸入至接头主体1的小直径孔12内。
其中，为保证进水管头3与接头主体1之间的防水密封效果，本实施例一的进水管头3的外圆周壁与接头主体1的大直径孔11的内壁之间分别卡装有密封胶圈4。
需进一步解释，如图1所示，大直径孔11的内壁设置有用于定位卡持凸起24前后位置且与水管卡持头2抵接的定位挡肩15，具体的：定位挡肩15与水管卡持头2的大直径段21抵接；在本实施例一装配过程中，通过定位挡肩15与水管卡持头2的定位抵接关系，本实施例一可以有效地保证水管卡持头2的卡持凸起24稳定可靠地卡持抵紧软质弹性水管。当然，本实施例一的并为对定位挡肩15的位置进行限制，即本实施例一的定位挡肩15还可以设置于小直径孔12的内壁，此时，定位挡肩15与水管卡持头2的小直径段22抵接。
需进一步指出，由于小直径段22的卡持凸起24的顶端的外径值较接头主体1的小直径孔12的直径值大，当进水管头3旋紧到位时，软质弹性水管的管壁卡紧于小直径段22的卡持凸起24与小直径孔12的后端开口的边缘部之间，进而实现密封以及锁紧。
另外，如图1所示，本实施例一的接头主体1的护套套装部14外围螺装有外层管套5，外层管套5的中心孔的内壁设置有第一锥形面51，接头主体1的护套套装部14前端部对应第一锥形面51设置有第二锥形面13。需进一步解释，软质弹性水管的外围套装一水管保护套；在水管保护套安装过程中，水管保护套的一端部套入至接头主体1的护套套装部14外围；待水管保护套套入护套套装部14到位后，旋紧外层管套5；当外层管套5旋紧到位后，水管保护套卡紧于 第一锥形面51与第二锥形面13之间。
综合上述情况可知，通过上述结构设计，本实施例一的结构改良的软质弹性水管接头通过两步法来实现软质弹性水管、水管保护套装配连接，即本实用新型具有设计新颖、结构简单、装配方便、稳定可靠性好的优点，即能够有效地适用于软质弹性水管连接。
实施例二，如图2所示，本实施例二与实施例一的区别在于：接头主体1的护套套装部14外围套装有铝压扣环6；在本实施例二工作过程中，水管保护套通过铝压扣环6卡装于接头主体1的护套套装部14外围。
实施例三，如图3所示，本实施例三与实施例一的区别在于：接头主体1的护套套装部14配装有保护套压环7，保护套压环7包括有分别呈半圆环形状的第一压环体71、第二压环体72，第一压环体71与第二压环体72螺接，保护套压环7的芯部开设有由第一压环体71、第二压环体72围装而成的套装孔，接头主体1的护套套装部14嵌插于保护套压环7的套装孔内。在本实施例三工作过程中，水管保护套通过保护套压环7卡装于接头主体1的后端部外围。
以上内容仅为本实用新型的较佳实施例，对于本领域的普通技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本实用新型的限制。
