Description
本发明涉及消防带接头，尤其是一种多元同传防脱拽消防管接头。
当前，随着高层建筑、大面积场(厂)、库、房广泛使用，灭火抢险救援和社会救助日益复杂，消防工作面临着诸多严峻的考验。如：消防员自身背负的压缩空气瓶体积大、重量大，且压缩空气瓶储存的压缩空气量有限，严重限制了消防员的救援活动能力，造成了许多不必要的生命危险和财产损失；而且，电、音频和视频无法传送，指挥中心不能及时了解消防员和火灾现场的实际情况，无法对现场进行有效的管控和对现有资源的合理调度，及卡式消防接口在火灾现场水带在拖拽过程中因推环接触地面，由于摩擦或在上楼梯碰到台阶等障碍物时位于公接头上的推环被非人为意愿推动后导致的公母接头自动打开情况，致使灭火介质在此处打开无法流至消防员的情况。
多元同传消防接头应用的一般为内置式和外置式，内置式消防接头，气管位于水带内部，由于水压常规在0.7-2MPa左右气压一般为0.7MPa致使内部气管在高压时易被水压扁致使空气传输受阻无法正常传输；另一种方式为外置式，空气接头在外侧水管外侧对接，因密封等因素造成拔插对接困难，令多元同传技术在消防现场应用上存在局限性。常规卡式接头因其推环没有自锁结构易在现场发生推环因外界因素发生滑动，至使公母接头分开的现象发生，在火灾现场处理此类问题增加很多宝贵时间。

所述水带母接头端部外侧通过螺纹与接合环连接，接合环外部套有防护圈；所述水带母接头内壁开设用来安装密封圈的密封槽，该密封圈密封在水带母接头和水带公接头之间。
所述接合环内侧设置有止退锁，所述水带公接头上端部设置外凸台，外凸台插入接合环后，卡在止退锁内；所述止退锁包括径向弹卡锁块、弹簧片、锁块导座，接合环内侧开设安放锁块导座和径向弹卡锁块的内槽，径向弹卡锁块内侧通过螺钉连接弹簧片， 弹簧片带动径向弹卡锁块在锁块导座内径向移动，所述水带公接头外部空套有推环，推环前端能顶压在径向弹卡锁块的斜面上，迫使径向弹卡锁块缩回。

相较于现有技术，本发明具有以下有益效果：
本发明避免内置式消防接头，气管位于水带内部，由于水压常规在0.7-2MPa左右气压一般为0.7MPa致使内部气管在高压时易被水压扁致使空气传输受阻无法正常传输；另一种方式为外置式，空气接头在外侧水管外侧对接，因密封等因素造成拔插对接困难。将压缩空气、电路和光纤用一根并联水带传输，空气管路不占用水带内部空间，也避免因空气管路因水压大于空气管路压力时空气管路被水压扁情况，并且接头另一端穿过接头内为同轴设计，可以快速插接多根消防带，在一个对接动作下，同时完成多对公母接头的相应精准对接。在火灾发生时，可以同时将水、气、电、音视频一并接通，且在公接头上有防脱拽装置避免外界因素打开，安装位置方便单手操作。
通过并联在水管外侧的气管将压缩空气由火灾现场外面输送到里面每个消防员，减轻了消防员自身携带救援设备的体积和重量，使压缩空气源源不断地输送给消防员，从而克服了消防员自身携带的气量不足这种情况，极大地增强了消防员的活动能力。
光纤接头包含电和光纤，也将通过接头内部由火灾现场外面连通到里面每个消防员，进行电源、音频和视频传输，既可满足消防现场照明设备的用电需求，也可实现对火灾 现场和消防员情况全面监控，使指挥中心能第一时间里了解火灾现场和消防员的情况，以实现指挥中心对现场进行有效的管控和对现有资源的合理调度。
由于水带接头内部同轴式设计，使得插接变得极为快捷，仅需一步插接，可以同时完成所有媒介的连接，而且同轴式设计不会产生误插，对准精度高，在火灾现场能够争取到更多的时间。
在水带公接头外部，防脱拽结构也就是推环锁止机构简单易操作，提高水带接头的安全性。按钮与推块一同在锁紧块内沿轴向直线运动进而推动推环轴向移动，推环推开径向弹卡锁块，然后使水带公接头脱离水带母接头，当水带公接头连接好水带母接头后，当推环下推至最下端时，松开按钮，顶块被弹簧顶出，这时推块内侧的底卡台就会卡住顶块的下边缘，从而锁止推块，由于推块和推环用螺钉连接固定，也就是锁止了推环的轴向移动，推块和推环处于自锁状态，防止因拖动原因推环轴向移动从而打开径向弹卡锁块造成公母接头打开的危险。
为了防止水冲破气带接头处的两道密封圈，而造成气带中进水的可能性，我们在两道密封圈之间开设能引流至水带接头外部的排水孔，由于水流朝一个方向走，所以第二道密封圈仍有密封压力，在第二道密封圈之前开设排水孔，而排水孔对外没有压力，所以水只能排出外部，不会再冲破第二道密封圈，就算两道密封圈全部冲破，由于气带接头内的气压要高，水只会通过排水孔排出接头外部，保证不会进入压力大的气带中，所以如果外侧密封损坏，外侧管道中介质可通过此孔与外界相通，防止水管内部介质流入气管内部。
由于推块上下轴向要稳定带动推环轴向移动，特别是顶块是连接弹簧的，摇摆幅度大，所以在推块左右两端滑动槽内壁形成导轨导槽式的导向结构，顶块外侧与推块的内侧同样形成导轨导槽式的导向结构，所以设计这种推块与自己相邻的两个件之间均设置这种导向结构是有必要的，按钮按下后，能保证推块相对于顶块能导向稳定移动，还能保证按钮内侧面相对于顶面的外侧面的一个相对不动的平面滑动，所以从而保证了推块以及推环在轴向移动上的稳定性。

所述光电母接头通过三辐式母固定套架10固定在气带母接头内端接口的内壁，所述光电公接头通过三辐式公固定套架18固定在气带公接头内端接口的内壁；所述三辐式母固定套架、三辐式公固定套架均设计有轴向贯通通道，保证气体通过。光电母接头外部还套设有挡圈6，挡圈6的外边缘卡入气带母接头内壁的环槽内，光电公接头外部还套 设有挡圈17，挡圈17的外边缘卡入气带公接头内壁的环槽内。在图7图8中能显示，三辐式母固定套架、三辐式公固定套架均具有内套、外套以及内外套之间连接的三辐支架。内套固定光电公、母接头，外套固定在气带公、母接头内端接口的内壁。
所述光电母接头由外侧至内侧依次分布有负极线缆11、绝缘体12、正极线缆13、绝缘体14、光纤37；所述光电公接头由外侧至内侧依次分布有负极线缆19、绝缘体20、正极线缆21、绝缘体36、光纤38。
所述气带母接头内端接口内壁与气带公接头内端接口外壁设置有两道密封圈7，即气带母接头内端接口内壁开设有两处用来放置密封圈的密封槽，该密封圈密封在气带公接头内端接口外壁。
本发明避免内置式消防接头，气管位于水带内部，由于水压常规在0.7-2MPa左右气压一般为0.7MPa致使内部气管在高压时易被水压扁致使空气传输受阻无法正常传输；另一种方式为外置式，空气接头在外侧水管外侧对接，因密封等因素造成拔插对接困难。将压缩空气、电路和光纤用一根并联水带传输，空气管路不占用水带内部空间，也避免因空气管路因水压大于空气管路压力时空气管路被水压扁情况，并且接头另一端穿过接头内为同轴设计，可以快速插接多根消防带，在一个对接动作下，同时完成多对公母接头的相应精准对接。在火灾发生时，可以同时将水、气、电、音视频一并接通，且在公接头上有防脱拽装置即推环锁止机构避免外界因素打开，安装位置方便单手操作。

由于水带接头内部同轴式设计，使得插接变得极为快捷，仅需一步插接，可以同时完成所有媒介的连接，而且同轴式设计不会产生误插，对准精度高，在火灾现场能够争取到更多的时间。
所述气带母接头还开设排水孔，所述排水孔一端连通气带母接头内腔，另一端连通至水带母接头外部，所述排水孔要经过两道密封圈之间的位置再连通至气带母接头内腔。在排水孔处开设孔时需要开设工艺制造孔，后期再在工艺制造孔中封堵钢球8。
为了防止水冲破气带接头处的两道密封圈，而造成气带中进水的可能性，我们在两道密封圈之间开设能引流至水带接头外部的排水孔，由于水流朝一个方向走，所以第二道密封圈仍有密封压力，在第二道密封圈之前开设排水孔，而排水孔对外没有压力，所以水只能排出外部，不会再冲破第二道密封圈，就算两道密封圈全部冲破，由于气带接头内的气压要高，水只会通过排水孔排出接头外部，保证不会进入压力大的气带中，所以如果外侧密封损坏，外侧管道中介质可通过此孔与外界相通，防止水管内部介质流入气管内部。

在水带公接头外部，防脱拽结构也就是推环锁止机构简单易操作，提高水带接头的安全性。按钮与推块一同在锁紧块内沿轴向直线运动进而推动推环轴向移动，推环推开径向弹卡锁块，然后使水带公接头脱离水带母接头，当水带公接头连接好水带母接头后，当推环下推至最下端时，松开按钮，顶块被弹簧顶出，这时推块内侧的底卡台就会卡住顶块的下边缘，从而锁止推块，由于推块和推环用连接螺钉连接固定，也就是锁止了推环的轴向移动，推块和推环处于自锁状态，防止因拖动原因推环轴向移动从而打开径向弹卡锁块造成公母接头打开的危险。
