Description

一种活接连接管总成 技术领域
本实用新型属于管件技术领域，涉及一种活接连接管总成。
背景技术
在给排水工程中，需要通过管路对水进行输送，管路由各种管子连接而成。管子根据材料质地的不同可分为硬管和软管。管子与管子之间往往设置有接头，为了便于安装，在管子上固定活接接头被广泛使用。在连接管上设置活接接头就形成了活接连接管总成。
中国专利文献资料公开提出了一种活接弯头[申请号：CN 201520793998.5；公告号：CN 205065153 U]，包括螺帽，螺帽套接在弯头本体的一端上。螺帽上设有环状的内凹槽，弯头本体上设有与内凹槽适配的环状凸起，弯头本体套设有密封垫圈。螺帽、弯头本体和密封垫圈组成活接接头。
弯头本体的另一端上固定连接管，通过螺帽连接对接管时，将对接管插入到螺帽中，转动螺帽使螺帽与对接管形成螺纹连接，拧紧螺帽使对接管抵靠在密封垫圈上形成密封。拧紧螺帽后，对接管、螺帽和弯头本体固定成一整体，对接管与弯头本体不能再相对转动。当需要调整弯头本体另一端的朝向时，即需要转动弯头本体时，只能通过扭曲对接管来进行。当对接管为硬管时，对接管不能扭曲从而导致弯头本体的朝向不能调整；当对接管为软管时，虽然可以进行扭曲，但是会导致对接管管体结构发生改变，使得流通量改变，扭曲过大时还会使管壁贴靠形成断流点，导致管体不能通水。
发明内容
本实用新型的目的是针对现有技术存在的上述问题，提出了一种活接连接管总成，解决了现有的活接连接管总成中螺帽拧紧后螺帽与接头本体之间不能相对转动的技术问题。
本实用新型的目的可通过下列技术方案来实现：
一种活接连接管总成，包括接头本体，所述接头本体的一端固定连接有连接管，所述接头本体的另一端设置有连接部，所述连接部上套设有螺帽，所述连接部的外侧面上具有凸出的挡环，所述螺帽的内侧面上具有凸出的挡肩，所述螺帽内安装有密封垫圈，其特征在于，所述连接部与螺帽之间设置有套圈，所述连接部的外侧面上位于挡环的外侧卡接有挡圈，所述套圈可转动的套装在连接部上并限位于挡环与挡圈之间，所述套圈的内侧面与连接部的外侧面之间设置有密封圈，所述套圈的外侧面上具有呈环形的限位凸起，所述限位凸起位于挡肩与密封垫圈之间且挡肩能够抵靠在限位凸起的内端面上，所述密封垫圈贴靠在限位凸起的外端 面上。
连接时，将对接管插入到螺帽内，转动螺帽使螺帽与对接管形成螺纹连接，拧紧螺帽使螺帽的挡肩抵靠在限位凸起的内端面上，使对接管将密封垫圈压紧在限位凸起的外端面上，从而使螺帽、套圈、密封垫圈和对接管固定成一整体。由于套圈套装在连接部上并限位于挡环与挡圈之间，套圈不会从连接部上脱出，这样对接管通过套圈固定在连接部上，而套圈的内侧面与连接部的外侧面之间设置有密封圈，密封圈具有密封作用，保证了连接部与套圈之间的密封性。同时套圈能够在连接部上转动，当螺帽锁紧后需要螺帽与接头本体相对转动进行周向角度的调整时，握住接头本体与和螺帽，使套圈与连接部相对转动即可，转动过程中和转动后密封圈始终能够起密封作用，且套圈始终被挡环和挡圈限位于连接部上，使连接管与对接管连接稳定。因此本活接连接管总成中螺帽拧紧后在保证连接管与对接管实现密封稳定连接的同时，螺帽与接头本体之间还能够相对转动，并能够进行360°转动。
在上述的活接连接管总成中，所述连接部的外侧面与套圈的内侧面之间具有环隙，当套圈抵靠在挡环上时所述挡圈与套圈之间具有间隙。这样设置保证了套圈能够在连接部上转动，保证螺帽拧紧后螺帽能够在接头本体上转动。
在上述的活接连接管总成中，所述密封垫圈外端的内侧面上具有凸出的挡凸部，所述挡圈位于挡凸部的内侧。挡凸部将挡圈遮挡住，具有防拆作用。
在上述的活接连接管总成中，所述密封垫圈内端的内侧面上具有凸出的凸起部，所述套圈的外侧面上位于限位凸起的外侧设置有呈锥形的密封面，所述凸起部贴靠在密封面上并形成密封。这样设置可以提高套圈与密封垫圈之间的密封性能，保证连接管与对接管之间连接处的密封性。
在上述的活接连接管总成中，所述限位凸起的内端面上具有凸出的环形凸起，所述环形凸起套设在挡环上。环形凸起能够加强套圈的结构强度，保证套圈在转动过程中的稳定性。
在上述的活接连接管总成中，所述连接部的外侧面上位于挡环的外侧设置有定位槽，所述挡圈固定在定位槽内。定位槽对挡圈具有定位作用，避免挡圈从连接部上脱出，保证套圈在连接部上的连接稳定。
在上述的活接连接管总成中，所述连接部的外侧面上位于挡环与挡圈之间设置有固定槽，所述密封圈固定在固定槽内。固定槽对密封圈具有固定作用，防止密封圈在套圈套入连接部的过程中产生移位，保证密封圈的密封效果。
在上述的活接连接管总成中，所述固定槽有两个并在连接部上沿轴向依次排列。这 样设置保证了在套圈与连接部相对转动时套圈与连接部之间的密封性，保证了连接管与对接管之间连接处的稳定密封。
与现有技术相比，本实用新型具有以下优点：
套圈设置在螺帽与连接部之间，套圈上设置的限位凸起与螺帽的挡肩形成卡扣结构，套圈通过挡环和挡圈轴向限位于连接部上，且套圈能够在连接部上转动，使得螺帽被拧紧后还能够在连接部上转动。套圈上密封面和密封垫圈上凸起部的设置提高了密封性。两个密封圈的设置提高了密封性。

具体实施方式
以下是本实用新型的具体实施例并结合附图，对本实用新型的技术方案作进一步的描述，但本实用新型并不限于这些实施例。
实施例一
如图1-图3所示，一种活接连接管总成，包括接头本体1，接头本体1为弯头，其两端垂直设置。接头本体1的一端固定连接有连接管2，连接管2为双层PVC管，为软管。接头本体1的另一端设置有连接部1a，连接部1a上套设有螺帽3，连接部1a与螺帽3之间设置有套圈5，套圈5轴向限位于连接部1a上并能够在连接部1a上转动，套圈5的内侧面为圆柱面，连接部1a的外侧面为圆柱面。
连接部1a的外侧面上具有凸出的挡环1a1，连接部1a的外侧面上位于挡环1a1的外侧卡接有挡圈6，套圈5可转动的套装在连接部1a上并限位于挡环1a1与挡圈6之间。连接部1a的外侧面上位于挡环1a1的外侧设置有定位槽1a2，定位槽1a2内固定有挡圈6；或者连接部1a的外侧面上过盈固定有挡圈6，挡圈6位于挡环1a1的外侧。连接部1a的外侧面与套圈5的内侧面之间具有环隙8，套圈5的内侧面与连接部1a的外侧面之间设置有密封圈7。连接部1a的外侧面上位于挡环1a1与挡圈6之间设置有固定槽1a3，密封圈7固定在固定槽1a3内，密封圈7的外侧面贴靠在套圈5的内侧面上并形成密封。密封圈7有两个并 在连接部1a上沿轴向依次排列。
螺帽3的内侧面上具有凸出的挡肩3a，螺帽3内安装有密封垫圈4。套圈5的外侧面上具有呈环形的限位凸起5a，限位凸起5a位于挡肩3a与密封垫圈4之间，挡肩3a能够抵靠在限位凸起5a的内端面上，密封垫圈4贴靠在限位凸起5a的外端面上。限位凸起5a的内端面上具有凸出的环形凸起5b，环形凸起5b套设在挡环1a1上。当挡肩3a抵靠在限位凸起5a的内端面上时，环形凸起5b位于挡环1a1与挡肩3a之间。密封垫圈4内端的内侧面上具有凸出的凸起部4a，套圈5的外侧面上位于限位凸起5a的外侧设置有呈锥形的密封面5c，凸起部4a贴靠在密封面5c上并形成密封。密封垫圈4外端的内侧面上具有凸出的挡凸部4b，挡圈6位于挡凸部4b的内侧。
组装时，将螺帽3套装在套圈5上，使螺帽3的挡肩3a位于限位凸起5a的内侧，将密封圈7安装到固定槽1a3内，密封圈7的外侧部凸出于连接部1a的外侧面；然后将套圈5套装在连接部1a上，使套圈5的内端面抵靠在连接部1a的挡环1a1上，密封圈7受到套圈5挤压且密封圈7的外侧部贴靠在套圈5的内侧面上并形成密封，由于受到密封圈7的支撑，套圈5的内侧面与连接部1a的外侧面之间具有呈环形的环隙8；接着将挡圈6卡入到定位槽1a2内，此时套圈5被挡圈6和挡环1a1轴向限位于连接部1a上，且套圈5能够在连接部1a上转动；然后将密封垫圈4安装到螺帽3内，密封垫圈4的内端面贴靠在限位凸起5a的外端面上，密封垫圈4的凸起部4a抵靠在套圈5的密封面5c上并形成密封，密封垫圈4的挡凸部4b位于挡圈6的外侧。
连接对接管时，将对接管插入到螺帽3内，转动螺帽3使螺帽3与对接管形成螺纹连接，拧紧螺帽3使螺帽3的挡肩3a抵靠在限位凸起5a的内端面上，使对接管将密封垫圈4压紧在限位凸起5a的外端面上，从而使螺帽3、套圈5、密封垫圈4和对接管固定成一整体。由于套圈5套装在连接部1a上并限位于挡环1a1与挡圈6之间，套圈5不会从连接部1a上脱出，这样对接管通过套圈5固定在连接部1a上，而套圈5的内侧面与连接部1a的外侧面之间设置有密封圈7，密封圈7具有密封作用，液体也不会从套圈5与连接部1a之间的环隙8处漏出。同时套圈5能够在连接部1a上转动，当螺帽3锁紧后需要螺帽3与接头本体1相对转动来调节接头本体1上固定有连接管2一端的朝向时，握住接头本体1与和螺帽3，使套圈5与连接部1a相对转动即可，转动过程中和转动后密封圈7始终能够起密封作用，且套圈5始终被挡环1a1和挡圈6限位于连接部1a上，使连接管2与对接管连接稳定。因此本活接连接管总成中不仅具有螺帽3的活接功能，使连接管2与对接管安装方便，而且螺帽3拧紧后在保证连接管2与对接管实现密封稳定连接的同时，螺帽3与接头本体1 之间还能够相对转动，并能够进行360°转动，从而避免连接管2或者对接管发生扭曲，避免连接管2或者对接管扭曲损坏管体结构并影响液体的正常输送，提高了活接连接管总成使用的稳定性和可靠性。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
