具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例一
如图1-3所示，本发明优选实施例的一种快速接驳装置，包括装置本体1和管材2，装置本体1套设于管材2的外部，装置本体1的内部设有锁紧模块3。针对市面上存在的管材2与装置本体1容易脱离的现象，在装置本体1的内部设置锁紧模块3，利用自锁原理，大幅度提升装置的锁紧效果。
自锁原理的实现主要依赖锁紧模块3，具体的，锁紧模块3包括脱套31、垫片32、弹簧33和固定件34，脱套31套设于管材2的外部，垫片32位于脱套31的外侧前部，弹簧33位于脱套31的外侧中部，固定件34位于脱套31的末端。在管道连接方式中，为了保证装置本体1和管材2之间的连接强度，本发明所述的快速接驳装置采用自锁原理，使得在水压的外力作用下，管材2会紧紧锁紧在装置本体1中，当压力越大的时候，锁紧力就越大。脱套31的末端设有卡扣4，装置本体1的内部设有与卡扣4相配合的容纳槽5，固定件34位于卡扣4和管材2的接触面用以固定管材2，通过固定件34将管材2与装置本体1相固定，实现快速接驳装置的锁紧功能。
在本实施例中，弹簧33优选为压缩弹簧，是承受纵向压力的螺旋弹簧，利用多个开放线圈对外载压力供给抵抗力量。压缩弹簧的圈与圈之间有一定的间隙，当受到外载荷时弹簧33收缩变形，储存形变能。压缩弹簧对外载压力提供反抗力量，为装置本体1和管材2之间的连接强度提供辅助作用。
另外，为了更好的提升本装置的自锁效果，垫片32位于脱套31的外侧前部，给管材2和装置本体1的接驳提供保障。在本实施例中， 垫片32优选为U型，且垫片32的一侧设有拨块6，方便作业人员取放。
本发明所述的快速接驳装置中，固定件34由不锈钢材料制成。不锈钢具有焊接性、耐腐蚀性、抛光性、耐热性、耐腐蚀性好等优点。在本实施例中，脱套31的末端设有六个卡扣4，与之相配合的是固定件34数量也是六个。根据实际需要，卡扣和固定件34也可以设计成其它形状和数量。一般情况下，固定件34在G点卡紧管材2，而同一时间脱套31也和装置本体1在H点顶固。
本发明所述的快速接驳装置的具体应用如下：
(1)当需要安装管材时：首先，将垫片32拔出，放好备用；然后，将管材2和装置本体1水平对齐，再将管材2插入；接着，将管材2与脱套31向外拉出一点；最后，将垫片32放回原位，安装完成。
(2)当需要拆开管材时：首先，将垫片32拔出；然后，按下脱套31使H点不再顶固；接着，转动管材2，使G点不再卡紧；最后，把管材2拔出，将垫片32放回原位，拆开完成。
实施例二
如图4-6所示，本发明优选实施例的一种快速接驳装置，包括装置本体1和管材2，装置本体1套设于管材2的外部，装置本体1设有若干接驳模块10。具体的，各接驳模块10均包括脱套31、垫片32、弹簧33、固定件34和密封件9，脱套31套设于管材2的外部，垫片32位于脱套31的外侧前部，弹簧33套设于脱套31的外侧中部，固定件34位于脱套31的末端，密封件9位于装置本体1和管材2之间。采用该种设计，使得在各种情况下，作业人员都能轻松完成各种材质管材的接驳，适用范围广、操作简便。
如图5所示，密封件9包括第一密封圈91和第二密封圈92，第一密封圈91位于第二密封圈92和脱套31的中间。第一密封圈91为 O型圈，第二密封圈92为异形密封圈，呈A字形，且所述第二密封圈92的中间设有空圆环921。密封圈具有以下优点：(1)密封圈在工作压力和一定的温度范围内，具有良好的密封性能，并随着压力的增加能自动提高密封性能；(2)密封圈装置和运动件之间的摩擦力要小，摩擦系数要稳定；(3)密封圈抗腐蚀能力强，不易老化，工作寿命长，耐磨性好，磨损后在一定程度上能自动补偿；(4)结构简单，使用、维护方便，使密封圈有更长的寿命。如图5所示，本发明所述的快速接驳装置的密封方式采用的是双密封圈的结构，第一密封圈91位于装置本体1和管材2之间，当第一密封圈91受压变形时就会产生密封效果。因为每根管材之间都会存在尺寸上的差异，而这种差异可能会导致密封圈的压缩强度不够，从而形成渗漏。在本实施例中，第二密封圈92的独特设计正好可以解决这个问题。因为第二密封圈92的中间有一个小的空圆环921，当管材2尺寸偏大的时候相当于卸载空间，使空的圆环体积变小了，并使第二密封圈92本身产生扭矩，而且第二密封圈92的密封面积比传统的O型密封圈要大。当压缩强度改变的情况下，针对不同尺寸的管材，第二密封圈产生的变化，可以有效防止接驳装置渗漏现象的发生，从而更好的防漏；采用双密封圈的形式，提升接驳装置在使用过程中的密封效果，对于提升配合非国标管材时的密封效果尤为显著。
本实施例中，第一密封圈91和第二密封圈92由三元乙丙橡胶材料制成。三元乙丙橡胶是乙烯、丙烯和少量的非共轭二烯烃的共聚物，是乙丙橡胶的一种，因其主链是由化学稳定的饱和烃组成，只在侧链中含有不饱和双键，故其耐臭氧、耐热、耐候等耐老化性能优异，可广泛用于汽车部件、建筑用防水材料、电线电缆护套、耐热胶管、胶带、汽车密封件等领域。与其他常用的通用橡胶或特种橡胶相比，三元乙丙橡胶的主要性能优势在于以下几方面：(1)性价比高，是生胶密度最轻的常用橡胶；(2)优异的耐老化特性，耐天候、耐臭氧、耐日光、 耐热、耐水、耐水蒸气、耐紫外线、耐辐射等老化性能；(3)优异的耐化学药品特性，耐酸、碱、洗涤剂、动植物油、醇、酮等；杰出的耐水、耐热水、耐水蒸气性能，耐极性油性能；(4)优良的绝缘性能；(5)适用温度范围广。
在管道连接方式中，为了保证装置本体1和管材2之间的连接强度，本发明所述的快速接驳装置采用自锁原理，使得在水压的外力作用下，管材2会紧紧锁紧在装置本体1中，当压力越大的时候，锁紧力就越大。如图4所示，脱套31的末端设有卡扣4，装置本体1的内部设有与卡扣4相配合的容纳槽5，固定件34位于卡扣4和管材2的接触面用以固定管材2。在本实施例中，固定件34由不锈钢材料制成。不锈钢具有焊接性、耐腐蚀性、抛光性、耐热性、耐腐蚀性好等优点。在本实施例中，脱套31的末端设有六个卡扣4，与之相配合的是固定件34数量也是六个。根据实际需要，卡扣4和固定件34也可以设计成其它形状和数量。一般情况下，固定件34在G点卡住管材2，而同一时间脱套31也和装置本体1在H点卡住。在本实施例中，弹簧33优选为压缩弹簧，对外载压力提供反抗力量，为装置本体1和管材2之间的连接强度提供辅助作用。垫片32为U型，并且，垫片32的一侧设有拨块6，方便作业人员拿取垫片32。
此外，装置本体1由氯化聚氯乙烯材料制成。氯化聚氯乙烯是聚氯乙烯进一步氯化改性的产品，除了兼有聚氯乙烯的很多优良性能外，其所具有的耐腐蚀性、耐热性、阻燃性、机械强度等均比聚氯乙烯有较大的提高，其具有卓越的耐高温、抗腐蚀和阻燃性，而且与其他热塑性工程塑料比较，价格相对较低。因而，氯化聚氯乙烯是性能优良的新型材料，被广泛用于建筑、化工、冶金、造船、电器、纺织等领域，应用前景十分广阔。
本发明所述的快速接驳装置的使用方法如下：
(1)当需要安装管材时：首先，将垫片32拔出，放好备用；然 后，将管材2和装置本体1水平对齐，再将管材2插入；接着，将管材2与脱套31向外拉出一点；最后，将垫片32放回原位，安装完成。
(2)当需要拆开管材时：首先，将垫片32拔出；然后，按下脱套31使H点不再顶固；接着，转动管材2，使G点不再卡紧；最后，把管材2拔出，将垫片32放回原位，拆开完成。
综上所述，本发明所述的快速接驳装置操作简便，只需要几个步骤，且无需专业人员操作，无需热熔机或是粘结剂来辅助完成；省时省力，比传统的连接方式节省安装时间高达80％以上；可以在某些特殊场合使用，即使在没有电力、没有粘结剂或是在水里面都可以操作；可接驳符合国标公称直径的不同材质的管材；耐高温，在85℃水温条件下依旧能长期正常使用。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
