Description

一种管道用快速接头 技术领域
本实用新型属于管道连接件技术领域，特别涉及一种管道用快速接头。
 背景技术
在日常生产、生活中，许多流体都需要通过管道进行传输，但管道的长度有限，需要通过管接头将两段或多段管道连接，以增加管道的整体长度；管道与用水设备之间同样需要管接头连接。
公布号为CN201836571U的中国专利公开了一种管道快速接头，包括接头本体，接头本体内部沿管道插入方向依次设有：锁止帽，用于防止内部部件退出；锁止帽止挡部件，设于接头本体的管道插入端上，用于防止锁止帽退出；拆卸环，用于解除管道的卡止；卡环，具有环形弹性凸缘和若干个用于卡紧管道外壁的卡齿；锥座，与接头本体的内壁滑动连接，用于阻止卡环向管道插入方向运动；锥座凸肩，设于接头本体的内壁上，用于阻止锥座向管道插入方向运动；O型密封圈，用于在管道插入接头后与管道外壁形成密封连接；O型密封圈凸肩，设于接头本体内壁上，用于阻止O型密封圈向管道插入方向运动；止挡部件，设于接头本体内壁上，用于阻止管道沿插入方向运动。
上述技术方案存在以下缺陷：上述快速接头作为软管的连接件使用时，软管端部插入接头本体内，卡环上的卡齿抵紧于软管外壁，当软管内通入液体并膨胀时，卡齿会进一步抵紧软管外壁并将软管卡止，防止软管从接头内脱落。在低纬度的夏季高温时，软管会受热软化，如果此时软管内的压力降低，或者没有通水时，卡齿依然会挤压软管，使得软管向内形变，导致软管在卡齿处的内径缩小，最终会降低软管内介质的流通量；而且，软管在接头内受热软化后，卡齿对软管的限位效果降低，软管不仅容易松动，甚至能直接将软管从接头内拽出，连接效果较差；此外，为保证接头本体的使用寿命，接头本体整体采用铜类金属制造，不仅将材料本身更贵，而且还需要经过多次加工在与其他部件组装，导致上述接头的生产成本较高，收益有限，不利于市场竞争。
 实用新型内容
本实用新型的目的是针对现有技术存在的上述问题，提出了一种管道用快速接头，本实用新型所要解决的技术问题是：如何提升接头与管道的连接效果。

综上所述，本实用新型对比于现有技术的有益效果为：
待连接管道直接从限位组件插入插接槽内，使得待连接管道的内壁与衬管的外壁贴靠，由衬管撑住待连接管道的内壁，即使被限位组件挤压，待连接管道内径也不会在衬管处缩小，管道在高温或低温环境下，限位组件都能够保证对管道的限位质量，可有效提升本快速接头与管道的连接效果。而且，接口整体采用塑料，再通过卡箍将限位组件与接口连接为一个整体，能够降低本快速接头的生产成本；连接端外的护套则能够提升连接端的结构强度及耐磨性，保证本快速接头的使用寿命。

 具体实施方式
以下结合附图对本实用新型作进一步详细说明，但本实用新型并不限于这些实施例。
一种管道用快速接头，如图1-图9所示，包括接口100、卡箍200、限位组件300，接口100内设置有供管道1插接的衬管110，衬管110内具有连通管道1的流道111，衬管110的外端位于限位组件300内，衬管110与接口100之间具有供管道1端部插入的插接槽120，卡箍200将限位组件300连接于接口100端部，管道1穿过限位组件300并插接于衬管110外壁后，限位组件300与衬管110配合对管道1限位。
接口100的材质包括PPSU塑料或低价金属；在一些实施方式中，衬管110与接口100之间采用卡接、螺纹连接或一体成型的方式连接，衬管110与接口100的材质相同。
衬管110外端具有便于待连接管道1端部插接的导向面112，流道111外端具有与待连接管道1连通的导流面113。
如图1、图3所示，接口100远离衬管110的端部具有连接端130，连接端130内部与流道111连通，连接端130用于连接适配的接头或者用水器。连接端130外包覆有护套131，且连接端130的外壁形状与护套131的外壁形状相同；例如，连接端130外壁为六角状，则护套131的外部形状也为六角状。如图8、图9所示，在一些实施方式中，护套131仅覆盖连接端130的端部，不需要将连接端130的外壁完全包裹。
进一步地，护套131的材质为硬质金属，硬质金属优选为不锈钢、高强度铝合金或其他合金材料，护套131用于加强连接端130的结构强度及耐磨性，从而增加其使用寿命。
卡箍200套设于接口100的端部，卡箍200的两端分别具有卷边一210、卷边二220，卷边一210与接口100外的凸起140贴合，卷边二220与限位组件300的外壁贴合。
如图3-图6所示，限位组件300包括基座310、压帽320、卡环330以及解锁管340，卡箍200包裹在基座310外并与接口100连接，且卷边二220与基座310的端部贴合，基座310内具有相连通的限位槽311、装配孔312，卡环330设置于限位槽311的槽底，压帽320设置于限位槽311的开口处并靠近接口100，且压帽320与限位槽311配合对卡环330限位，卡环330内周向间隔设置有若干卡齿331，各卡齿331均具有弹性形变性能，各卡齿331均向接口100方向弯折并靠近衬管110的外壁，为保证卡齿331能够顺利嵌入管道1外壁，各卡齿331的端部均开设有尖刃332，且尖刃332能够为插入卡环330内的管道1导向，压帽320靠近卡齿331的一端开设有供各卡齿331形变的让位面321；解锁管340滑移设置于装配孔312内，解锁管340内具有供管道1插入的中心孔341，装配孔312内具有台阶面3121，台阶面3121对解锁管340内端的插头342限位，使得插头342能够在台阶面3121与卡齿331之间滑移，插头342外壁具有能够挤压卡齿331向让位面321形变的斜面3421。
如图4所示，优选地，压帽320的外壁设置有凸缘322，限位槽311内设置有供凸缘322安装的定位槽3111，定位槽3111对凸缘322限位，从而保证卡环330在限位槽311内的位置，同时，也能够让限位组件300形成一个整体的部件，以便组装。
接口100靠近基座310的端部开设有安装槽150，安装槽150内设置有密封圈151，压帽320与安装槽150配合对密封圈151限位，密封圈151的内圈能够抵紧于管道1外壁，从而提升管道1与插接槽120之间的气密性。
本实用新型的工作原理如下：
待连接的管道1为软管，管道1端部插入中心孔341，再经过导向面112、尖刃332的导向，使得管道1端部更容易的插接于衬管110外，在管道1端部进入插接槽120后，管道1与流道111连通，且卡齿331将管道1压紧在衬管110外，密封圈151内壁与管道1外壁抵紧，本快速接头与待连接管道1的连接完成。如果管道1因受力而脱离插接槽120时，卡齿331会被管道1带动而向插头342方向形变，使得卡齿331进一步卡入管道1外壁并将管道1更进一步的压在衬管110外壁，避免管道1与接口100分离。
管道1与本快速接头拆分时，只需要按压解锁管340，使得插头342将各卡齿331向让位面321方向挤压，管道1失去卡齿331的限位便可从插接槽120内抽离。
连接端130与用水器连接后，管道1便可为用水器输送介质；连接端130与其他接头连接后，管道1便可为该接头输送介质。管道1输送介质的过程中，导流面113可以引导介质进入流道111内，从而避免介质在衬管110处受阻。
以上所述仅是本实用新型的示范性实施方式，而非用于限制本实用新型的保护范围，本实用新型的保护范围由所附的权利要求确定。
