具体实施方式
下面参照附图详细地说明本发明的具体实施方式。在各附图中，相同的附图标记表示相同或相应的技术特征。
图1是根据本发明的一个实施方式的连接件的示意性立体图。图2和图3分别是图1中的连接件两端的示意性端视图。图4为图1中的连接件的示意性侧视图。
从图中可以看出，该连接件10可以具有周向侧壁11、第一端壁12和第二端壁13。如图中所示的实施方式中，第一端壁12和第二端壁13可以分别设置在周向侧壁11的两个末端位置处。第一端壁12和第二端壁13分别连接或固定至所述周向侧壁11，例如与其组装在一起，或者一体地形成。可以了解，该连接件10可以由适当的材料例如塑料或金属制成，根据具体的情况具有适当的厚度、刚 度，以满足连接力的要求。
图中周向侧壁11上的周向孔(或镂空部)11a是为开模需求或便于加工而增加的工艺孔，还可用于将刀具伸进内部空腔进行切削等，简化了加工步骤，能够有利地降低加工成本。根据具体的加工需要可以采用适当的工艺孔形状，该工艺孔本身并不影响连接件10的使用。可以了解，在工艺水平允许的情况下，也可以省去该工艺孔。
从图中可以看出，周向侧壁11限定了连接件10的内部空腔14。可以理解，在可选的实施方式中，为了便于加工、便于操作等，周向侧壁11的内、外周面可以限定为圆形柱面。在其它可选实施方式中，根据例如空间等具体需要，也可以将周向侧壁11的内、外周面设计成其它形状的柱面；或者并不局限于柱面设计，也可以设计成锥面、或者不规则形面等。
在图示实施方式中，在连接件的外周面上分布有沿连接件10的轴向延伸、沿周向分布的凸条15，适于为手动操作或工具操作旋拧连接件10时提供一定的阻尼，增加阻力、避免操作时打滑，使得操作更加可靠、增强用户体验。关于连接件10的具体连接方式、操作方式，会在下文中结合图8-10进行详细描述。
在可选的实施方式中，替代地，也可以在连接件的外周面上形成有其它类型的阻尼部，用这些其它类型的阻尼部来替代凸条15。例如，可以将这些凸条设计成曲线状的，甚至改成刻痕、凹槽、凹或凸的图案等。再例如，这些其它类型的阻尼部可以是分布在连接件的外周面上的分散的点状的凸部或凹部。在另外的实施方式中，也可以通过增加连接件的外周面的表面粗糙度来实现。
如图中所示，该连接件10可以具有第一端壁12。第一端壁12中可以提供有第一通孔16，第一通孔16将内部空腔14与连接件10的外部连通。根据图示的实施方式，该第一通孔16可以包括第一圆孔16a以及在第一圆孔16a的周边上的第一引导槽16b。
在可选的实施方式中，第一引导槽16b的数量可以设置成多于一个并且沿第一圆孔16a的周向均布。在图示示例中示出了两个第一引导槽16b，并且两个第一引导槽16b沿第一圆孔16a的直径对置地分布。可以理解，在其它实施方式中，如果有三个、四个等第一引导槽16a，则可以沿圆周每隔120度、90度等均匀分布。非均匀的分布也是允许的。
在图示实施方式中，第一端壁12还可以具有形成在第一圆孔16a的圆周处的第一周向限位缺口19a。可以了解，根据具体实施方式，也可以不设置该第一周向限位缺口19a，或者也可以设置更多数量的该第一周向限位缺口19a。下文中会结合图8-10对其作用进行阐述。
如图2中所示，该连接件10还可以具有第二端壁13。第二端壁13中可以提供有第二通孔17，第二通孔17将内部空腔14与连接件10的外部连通。根据图示的实施方式，第二通孔17包括第二圆孔17a以及在第一圆孔17a的周边上的第二引导槽17b。
在可选的实施方式中，第二引导槽17b的数量可以设置成多于一个并且沿第二圆孔17a的周向均布。在图示示例中示出了两个第二引导槽17b，并且两个第二引导槽17b沿第二圆孔17b的直径对置地分布。可以下理解，在其它实施方式中，如果有三个、四个等第二引导槽17b，则可以沿圆周每隔120度、90度等分布。非均匀的分布也是允许的。
可以了解，第二端壁13上的第二通孔17的形状、尺寸、分布的角度位置等并不必与第一端壁12上的第一通孔16的形状、尺寸、分布的角度位置等相同。
在图示实施方式中，第二端壁13还可以具有形成在第二圆孔17a的圆周处的第二周向限位缺口19b。可以了解，根据具体实施方式，也可以不设置该第二周向限位缺口19b，或者也可以设置更多数量的该第二周向限位缺口19b。第二周向限位缺口19b的结合和工作原理类似于第一周向限位缺口19a。
可以了解，在可选的实施方式中，第一通孔16及第二通孔17并不局限于如图中所示的具体形状。例如，只要第一通孔16及第二通孔17为非圆形形状，即能够实现轴向连接功能。
图5是沿图2中A-A剖取的剖视图。图6是沿图3中B-B剖取的剖视图。图7是沿图4中C-C剖取的剖视图。
结合这些剖视图可以看出，在该实施方式中，第一端壁12的在内部空腔14内的一侧上沿周向距第一引导槽16b一定距离处可以设置有第一凸部18。
类似地，可以理解，在可选的实施方式中，第二端壁13的在内部空腔14内的一侧上沿周向距第二引导槽17b一定距离处也可以设置有第二凸部(未图示)。
从图5和图6中还可以看出，在该实施方式中，第一端壁12和第二端壁13的厚度并不相同。可以理解，在可选的实施方式中，可以根据具体的需要，考虑例如但不限于连接力度、制造材料、安装空间等各种情况来设计第一端壁12、第二端壁13及周向侧壁11各自的厚度。
本发明的一个方面还提供了包括前述任一实施方式中的连接件的连接组件。这种连接组件还可以包括第一待连接部件(未图示)上与第一通孔形状一致的第一连接头以及第二待连接部件(未图示)上与第二通孔形状一致的第二连接头。第一通孔和第二通孔的形状适于为非圆形形状，因而第一连接头可以适于穿过第一通孔进入内部空腔、第二连接头可以适于穿过第二通孔进入内部空腔，并在连接件旋转一定角度后在内部空腔内分别接合至第一端壁、第二端壁，从而实现第一待连接部件与第二待连接部件之间的可靠的轴向连接。
结合图8至图10中的连接组件的示例将更易于理解该方面的连接组件的结构、原理及优点。
图8是根据本发明的一个实施方式的连接组件的示意图，其中连接组件处于拆解状态。图9是图8中的连接组件的示意图，其中连接组件处于连接状态。图10是处于连接状态的图9中的连接组件的剖视图。
如图中所例示的，连接组件100可以包括如前述任一实施方式的连接件10。另外，连接组件100还包括第一待连接部件(未完整示出)上与连接件10的第一通孔16形状一致的第一连接头20以及第二待连接部件(未完整示出)上与第二通孔17形状一致的第二连接头30。
更具体而言，在图8至图10中例示的是一种补胎机中的连接组件，其中第一待连接部件为补胎机中的补胎液连接管210(见图12)，而第二待连接部件为补胎机中的阀体220(见图12)。
从图中可以看出，该实施方式中，第一连接头20可以包括具有第一开口端的第一圆柱部21及设置在第一圆柱部上的第一挂耳22；第二连接头30可以具有包括第二开口端的第二圆柱部31及设置在第二圆柱部上的第二挂耳32；第一圆柱部21的外周上可以形成有第一周向限位凸起23；在第二圆柱部31的外周上可以形成有第二周向限位凸起33。
结合图8至图10可以理解，第一连接头20的第一圆柱部21及第一挂耳 22的形状分别与连接件10的第一圆孔16a及第一引导槽16b形状一致。在需要连接时，可以使第一圆柱部21及第一挂耳22穿过第一圆孔16a和第一引导槽16b，之后将连接件10旋转一定角度后第一挂耳22即可以在内部空腔内接合在第一端壁12的内侧表面上，实现第一连接头20与连接件10之间的轴向连接。在图示示例中，连接件10旋转90度即可实现可靠连接。
类似地，第二连接头30的第二圆柱部31及第二挂耳32的形状分别与连接件10的第二圆孔17a及第二引导槽17b形状一致。在需要连接时，可以使第二圆柱部31及第二挂耳32穿过第二圆孔17a和第二引导槽17b，之后连接件10旋转一定角度后第二挂耳32即可以在内部空腔内接合在第二端壁13的内侧表面上，实现第二连接头30与连接件10之间的连接。
可以了解，在实际操作中，可以是先将第一连接头20和第二连接头30伸入连接件10内，然后再将连接件10旋转一定角度来实现连接。
前面结合图5和图7描述了第一端壁12内侧的第一凸部18，并提及了第二端壁13内侧的第二凸部。在第一挂耳22及第二挂耳32接合在连接件10中时，该第一凸部和第二凸部可以通过分别与第一挂耳和第二挂耳接合而限定连接件相对于第一连接头和第二连接头的周向接合位置，使它们能够有效地与连接件10的第一端壁和第二端壁接合。具体地，第一挂耳和第二挂耳会在连接件转到适当的周向位置处时阻挡住该第一凸部和第二凸部，从而限制连接件相对于第一连接头和/或第二连接头的进一步相对转动，将其保持在最佳的连接位置。可以理解，不论第一挂耳及第二挂耳的数量如何，均可以仅设置一个第一凸部和/或仅一个第二凸部，同样能够实现良好的定位效果。
如图10中所示，由于该实施方式中第一待连接部件为补胎机中的补胎液连接管，而第二待连接部件为补胎机中的阀体，所以，第一连接头20可以具有第一开口端，并且第二连接头30可以具有第二开口端。具体地，在该实施方式中，第一开口端位于第一圆柱部21的端部，第二开口端位于第二圆柱部31的端部。如此，在第一连接头20、第二连接头30与连接件10接合的状态下，第一连接头的第一开口端可以密封地伸进所述第二连接头的第二开口端内，从而，第一开口端和第二开口端可以连接形成流体通路。
图11是图8中的连接组件中的一个连接头的示意图。从图11可以看出， 在第一连接头20的第一圆柱部的靠近末端的外圆周上可以设置有一圈凹槽24，可用于在其中嵌入密封圈40(见图10)，实现其与第二连接头30的内圆周的流体密封，防止介质泄漏、保证连接部分工作可靠。
图8和图11中在第一连接头20和第二连接头30的外周侧上分别提供有第一周向限位凸起23和第二周向限位凸起33。在将第一连接头20连接到连接件10时，先把第一连接头20伸进连接件10的第一通孔16，然后沿着设定的方向旋转连接件10，当接合到位时，第一周向限位凸起23可以稍微地卡接在第一端壁12的第一圆孔16a内的第一周向限位缺口19a中，产生到位的手感作为位置对齐的指示。可以理解，类似的设计同样适用于第二连接头33的第二周向限位凸起及第二端壁12的第一圆孔17a内的第二周向限位缺口19b。第一周向限位凸起、第二周向限位凸起的数量适于分别具第一周向限位缺口、第二周向限位缺口的数量、周向分布位置对应。
在此需要指出的是，当第一端壁的第一通孔和/或第二端壁的第二通孔分别为其它非圆形状时，例如椭圆形、多边形、不规则形状等，第一连接头和第二连接头也可以采用相应的形状，以允许第一连接头和第二连接头穿过第一通孔和第二通孔，并且在连接件旋转一定角度后通过其与第一端壁和第二端壁的内侧相接合而形成可靠的轴向连接。
可以理解，在可选的实施方式中，当连接组件不是用于补胎机中时，其同样可以设置有相应的第一开口端、第二开口端等相应特征，以适于可靠地输送流体。
本发明的另一方面提供了一种补胎机。该补胎机中可以设置有如前述任一项实施方式的所述的连接组件。
例如，在一个可选的实施方式中，补胎机可以具有阀体、补胎液连接管及空气压缩机连接管，补胎液连接管及空气压缩机连接管分别通过阀体可以连通至补胎机的排出嘴，并且补胎液连接管与阀体之间可以通过连接组件连接。此时，补胎液连接管与阀体可以分别作为第一待连接部件和第二待连接部件。可以看出，这样设置的是一种两用补胎器，通过排出嘴，其既能够排出补胎液进行补胎，又能排出空气给轮胎进行充气。
图12示出了该实施方式的补胎机的排出机构的示意图。
根据图中的例示，在该排出机构200中，补胎液连接管210的一端和空气压缩机连接管230的一端分别连接至阀体220。补胎液连接管210的另一端可以连接至补胎液容器(未图示)，空气压缩机连接管230的另一端可以连接至空气压缩机(未图示)。阀体220内可以设置有堵头260，堵头260能够在阀体220内来回滑移，从而实现阀体连通在补胎液容器与空气压缩机之间的切换。当空气压缩机连接管230处的压力大于补胎液连接管210处的压力时，堵头260移到补胎液连接管210处，排出嘴250适于为轮胎充气；当空气压缩机连接管230处的压力小于补胎液连接管210处的压力时，堵头260移到空气压缩机连接管230处，排出嘴250适于排出补胎液，进行补胎操作。
在图12中，补胎液连接管210与阀体220之间的连接有利地采用了本发明的前述实施方式中的连接组件，连接件240连接在补胎液连接管210与阀体220之间。对于补胎液连接管和阀体的密封装拆的这种简易结构设计，用于在补胎机这类产品较小空间内进行装拆了提供方便。
可以理解，虽然本说明书中结合补胎机的示例描述了连接件及连接组件的应用，但是，关于本申请所要求的连接件及连接组件并不局限用于补胎机中，而是适用于任何需要轴向连接的设备中。
本发明的技术范围不仅仅局限于上述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对上述实施方式进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
