具体实施方式
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案做详细的说明。
参考图1至图6，本发明的第一种实施例提供一种管卡100，包括第一耦接段11和第二耦接段12，第一耦接段11和第二耦接段12用于将管件端对端地固定在一起；
第一耦接段11的一端和第二耦接段11的一端相互别合，第一耦接段11的另一端和第二耦接段12的另一端螺接。
其中，管件的端部具有圆柱形的外表面。第一耦接段11和第二耦接段12跨接在管件端对端的连接部，第一耦接段11和第二耦接段12内壁与管件贴合，第一耦接段11和第二耦接段12跨接于管件上的两端分别通过别合的方式和螺接的方式进行连接。
具体地，第一耦接段11的一端延伸出别脚连接件101，第二耦接段12的一端延伸出别柱连接件，别脚连接件101和别柱连接件别合。
本实施例中所述的“别合”，为别脚连接件101伸入别柱连接件中并与别柱连接件相抵形成稳固的连接。
更进一步地，别脚连接件101包括从第一耦接段11一端的两侧边缘分别延伸出的第一别脚101a和第二别脚101b；别柱连接件包括从第二耦接段12的一端延伸出的连接体102a，以及与连接体102a连接的别柱102b，其中，连接体102a与别柱102b的圆周面连接且二者为一体成形，连接体102a卡入第一别脚101a和第二别脚101b之间，别柱102b与第一别脚101a和第二别脚101b相抵。
具体地，第一别脚101a和第二别脚101b之间，形成间隙，该间隙大于连接体102a的宽度，连接体102a可通过此间隙，使得别柱102b与第一别脚101a和第二别脚101b的端部相抵，实现第一耦接段11和第二耦接段12一端的相互别合，从而实现两种结构体的纵向和横向的相互别合，但轴向仍可运动，最终实现组装体的两个结构的相互开合。
第一别脚101a和第二别脚101b沿延伸方向逐渐变细，在保证强度的同时，最大限度的节约材料，降低生产成本。
第一别脚101a和第二别脚101b的端部设有与别柱102b相适配的弧形面，别柱102b与弧形面相抵，使得别柱102b与第一别脚101a和第二别脚101b之间的别合更加稳固。
第一耦接段11的外表面一侧设有与第一别脚101a相连接的第一加强筋103；
第一耦接段11的外表面另一侧设有与第二别脚101b相连接的第二加强筋104。
具体地，第一加强筋103分布于第一耦接段11外表面的一侧，从螺接的一端延伸到别合的一端，第二加强筋104分布于第一耦接段的另一侧，从螺接的一端延伸至别合的一端。即第一加强筋103和第二加强筋104的形状为弧形，且与第一耦接段11内表面的弧段同心，第一加强筋103和第二加强筋104的设计，能够有效加强第一别脚101a和第二别脚101b的连接强度。
第一加强筋103和第一别脚101a为一体成形；第二加强筋104与第二别脚为一体成形。一体成形的设计，能够进一步加强第一别脚101a和第二别脚101b的连接强度。
连接体102a沿延伸方向逐渐变细。
具体地，连接体102a设置在第二耦接段102一端的外表面中部，作为一种优选的实施方式，连接体102a与第二耦接段102为一体成形。
为了加强连接体102a的连接强度，连接体102a面向所述第一耦接段的一侧设有过渡结构102c。
进一步地，第二耦接段12的外表面两侧分别设有第三加强筋105和第四加强筋106。
第三加强筋105分布于第二耦接段12外表面的一侧，从螺接的一端延伸到别合的一端，第四加强筋106分布于第二耦接段12的另一侧，从螺接的一端延伸至别合的一端。即第三加强筋105和第四加强筋106的形状为弧形，且与第二耦接段12内表面的弧段同心，第三加强筋105和第四加强筋106的设计，能够有效加强第二耦接段12的强度。
第一耦接段11的内表面两侧设有与管件接触的第一弧段107，第一弧段107为半椭圆形，第一弧段107卡入管件的定位槽中实现定位。更进一步地，第一弧段107的圆心到第一弧段107端部的第一半径a，大于第一弧段107圆心到第一弧段107中端的第二半径b。作为一种优选的实施方式，第一半径a大于第二半径b约1-5毫米。
第二耦接段12的内表面两侧设有与管件接触的第二弧段108，第二弧段108为半椭圆形。更进一步地，第二弧段108的圆心到第二弧段端部的第三半径c，大于第二弧段108圆心到第二弧段108中端的第四半径d。作为一种优选的实施方式，第三半径c大于第四半径d约1-5毫米。
具体地，第一耦接段11和第二耦接段12跨接在端对端的管件上时，其内部形成于管件贴合的接近圆环形的结构，由于第一耦接段11和第二耦接段12与管件接触的部分均为半椭圆形，因此围成的形状为椭圆形，可以使得第一耦接段11和第二耦接段12两端连接时的紧固力通过椭圆形较长半径和较短半径配合产生的杠杆力矩产生出向心的变形力量，抱紧管件，使得第一耦接段11和第二耦接段12的内壁更加贴合管件。
进一步地，第一耦接段11螺接的一端设有第一螺栓孔109，第二耦接段12螺接的一端设有第二螺栓孔110，其中第二螺栓孔110为开口螺栓孔。
管卡还包括螺栓120，螺栓120穿过所述第一螺栓孔109和第二螺栓孔110实现第一耦接段11和第二耦接段12的螺接。
为了保证开口螺栓孔、螺栓的有效固定，第二螺栓孔110上设置有随型凸起111。
为了更好的实现第一耦接段11和第二耦接段12开合时的配合，第一耦接段11螺接的一端设有凸结构112，第二耦接段12螺接的一端设有与凸结构112相适配的凹结构。
此外，也可在第一耦接段设置凹结构，第二耦接段设置凸结构。
现有的双螺栓管卡装配的步骤为：拆卸螺栓-安装密封件-对齐管道-安装管卡-拧紧螺栓两次，共6个动作，约5-7分钟，而本实施例提供的管卡的安装步骤为：拆卸螺栓-安装密封件-对齐管道-拧紧螺栓一次，共四个动作，约3-4分钟，提高了约40-70％的安装效率。
综上，本实施例提供的管卡100，一端采用别合的连接方式，另一端采用螺接的连接方式，能够解决现有技术单螺栓快装管卡的销轴易脱落的问题，且相对于双螺栓的管卡，能有效提高装配效率。此外，第一耦接段和第二耦接段上加强筋的设计，可以将管卡锁紧时的应力传导至别脚连接件和别柱连接件上，降低管卡的应力集中，实现材料的节约，使材料更叫有效的发挥其性能。
参考图7，本发明的第二种实施例还提供一种管卡组件200，包括上述的管卡100，还包括与管卡100配合的密封件21。
参考图8，密封件21主体为圆环形结构，其外径与管卡100的内径相当，密封件21两侧向内延伸出唇边211，此外，密封件21内中部还形成有舌部212，舌部212用于对管件进行定位。作为一种优选的实施方式，舌部212为圆环形结构，即舌部212绕密封件21内壁一周。
可选地，参考图9和图10，舌部212包括多个间隔设置的段212a，即舌部212为分段结构。段212a的数量为4-10个且均匀分布。4-10个段的总弧长为所述密封件内表面圆周的40％-70％。分段结构的舌部，能够节约材料，降低生产成本。
参考图11和图12，舌部212呈齿轮状。齿轮状的舌部，能够保证定位的准确性以及节约材料，降低生产成本。
参考图8，密封件21面向所述第一耦接段和第二耦接段的一面设有凹面213，即外表面形成有凹面213，凹面213与所述第一耦接段和第二耦接段的内表面形成腔体。
参考图13和图14，密封件21的凹面213，在管件内未通入流体时，该凹面213与第一耦接段和第二耦接段的内壁形成的腔体214，当流体通过管道时，参考图15，密封件21内壁在压力的作用下收缩，凹面213与第一耦接段和第二耦接段的内壁接触，舌部212收缩至唇边211的内部，这样的设计可以减少舌部212的尺寸大小，进而减轻整个密封件的重量，降低生产成本。
此外，本实施例还提供另一种结构的密封件22，密封件22面向所述第一耦接段和第二耦接段的一面设有凹面222，参考图16，密封件22的唇边221上间隔设有定位凸起223，定位凸起223的端面形成定位面，在管件安装时定位面对管件进行定位，定位凸起223对管道的中心轴进行定位，作为一种优选的实施方式，每一侧的唇边上的定位凸起223的数量为4-10个且均匀分布。间隔设置的定位凸起223，有利于材料的节约，降低生产成本。

此外，参考图20，本实施例还提供第三种结构的密封件23，密封件23面向所述第一耦接段和第二耦接段的一面设有凹面232，密封件23的唇边231上间隔设有齿轮状定位凸起233，齿轮状定位凸起233的端面形成定位面，在管件安装时定位面对管件进行定位，齿轮状定位凸起233对管道的中心轴进行定位，齿轮状定位凸起233，有利于材料的节约，降低生产成本。
参考图21和图22，密封件23的凹面232，在管件内未通入流体时，该凹面232与第一耦接段和第二耦接段的内壁形成的腔体234，当流体通过管道时，参考图23，密封件23内壁在压力的作用下收缩，凹面232与第一耦接段和第二耦接段的内壁接触，相较于舌部定位，齿轮状定位凸起233可以更进一步节约材料。
本实施例提供的管卡组件200，其密封件外表面形成的凹面、间隔设置的定位凸起以及齿轮状的定位凸起，能够有效节约材料，降低生产成本。
参考图24至图26，本发明的第三种实施例还提供一种管卡300，包括第三耦接段31和第四耦接段32；
第三耦接段31的一端和第四耦接段32的一端通过多个别合机构相互别合，第三耦接段31的另一端和第四耦接段32的另一端通过多个螺接机构螺接。
本实施例提供的管卡300，第三耦接段31和第四耦接段32在轴向上具有较长的长度，因此其一端通过多个别合机构相互别合，另一端采用多个螺接机构进行螺接。
别合机构包括别脚、别柱和连接体，第三耦接段31的一端延伸出多个别脚311，第四耦接段32的一端延伸出多个连接体321，相邻的别脚311之间形成间隙，该间隙大于连接体321的宽度，连接体321可通过此间隙，使得连接体321上的别柱322与别脚311的端部相抵，实现第三耦接段31和第四耦接段32的相互别合，从而实现两种结构体的纵向和横向的相互别合，但轴向仍可运动，最终实现组装体的两个结构的相互开合。
更进一步地，连接体321与别柱的圆周面连接且二者为一体成形。
别脚311沿延伸方向逐渐变细，在保证强度的同时，最大限度的节约材料，降低生产成本。
别脚311端部设有与别柱322相适配的弧形面，别柱322与弧形面相抵。使得别柱322与别脚311之间的别合更加稳固。
第三耦接段31外表面分布有多条第五加强筋312，多条第五加强筋312分别与多个别脚311连接。第四耦接段32的外表面分布有多条第六加强筋323。
具体地，第五加强筋312分布于第三耦接段31外表面的一侧，从螺接的一端延伸到别合的一端，第六加强筋323分布于第四耦接段32的另一侧，从螺接的一端延伸至别合的一端。即第五加强筋312和第六加强筋323的形状为弧形，且第五加强筋312与第三耦接段11内表面的弧段同心，第六加强筋323与第四耦接段32内表面的弧段同心，加强筋的设计，能够有效加强别脚的连接强度。
第五加强筋103和别脚311为一体成形。一体成形的设计，能够进一步加强别脚311的连接强度。
进一步地，连接体321沿延伸方向逐渐变细，在保证强度的同时，最大限度的节约材料，降低生产成本。
为了加强连接体321的连接强度，连接体321面向所述第三耦接段的一侧设有过渡结构324。
多条第六加强筋323与多个连接体321间隔设置。
进一步地，参考图27，第三耦接段31的内表面的纵截面为半椭圆形，第三耦接段31内表面的纵截面的圆心到端部的第五半径e，大于圆心到中端的第六半径f。作为一种优选的实施方式，第五半径e大于第六半径f约1-5毫米。
进一步地，参考图28，第四耦接段32的内表面的纵截面为半椭圆形，第四耦接段32内表面的纵截面的圆心到端部的第七半径g，大于圆心到中端的第八半径h。作为一种优选的实施方式，第七半径大于第八半径约1-5毫米。
具体地，第三耦接段31和第四耦接段32跨接在管件上时，其内部形成于管件贴合的接近圆环形的结构，由于第三耦接段31和第二耦接段32与管件接触的部分均为半椭圆形，因此围成的形状为椭圆形，可以使得第三耦接段31和第四耦接段32两端连接时的紧固力通过椭圆形较长半径和较短半径配合产生的杠杆力矩产生出向心的变形力量，抱紧管件，使得第三耦接段31和第四 耦接段32的内壁更加贴合管件。
进一步地，第三耦接段31螺接的一端设有多个第三螺栓孔313，第四耦接段32螺接的一端设有多个第四螺栓孔324；
管卡300还包括多个螺栓，多个螺栓分别穿过所述多个第三螺栓孔313和第四螺栓孔324实现第三耦接段31和第四耦接段32的螺接。
为了保证开口螺栓孔、螺栓的有效固定，多个第四螺栓孔324上分别设置有随型凸起325。
为了更好的实现第三耦接段31和第四耦接段32开合时的配合，第三耦接段31螺接的一端设有凸结构314，第四耦接段32螺接的一端设有与凸结构314相适配的凹结构326。
此外，也可在第三耦接段设置凹结构，第四耦接段设置凸结构。
本实施例提供的管卡300，可以用于管道连接，管道补漏，管道应急处理等，而且可以根据管道的长度使用不同数量的组合，形成不同长度，应对不同场景。
综上，本实施例提供的管卡300，一端采用多个别合机构别合的连接方式，另一端采用多个螺接机构螺接的连接方式，能够解决现有技术单螺栓快装管不易扩展的问题。此外，第三耦接段和第四耦接段上加强筋的设计，可以将管卡锁紧时的应力传导至别脚和别柱上，降低管卡的应力集中，实现材料的节约，使材料更叫有效的发挥其性能。
参考图29和图30，本发明第四种实施例提供一种管卡组件400，包括上述的管卡300，还包括与管卡300相适配的密封件401。
具体地，密封件401的形状与管卡300的内部形状相适配，密封件401在轴向上有较长的长度，密封件401内设置有密封水线402，密封水线402与管件接触时，管道上的不平整，锈，或其他杂质，可以进入密封水线402的间隔，不影响密封。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
