下面阐述本发明实施例提供的一种空调内机及空调的优选技术方案。
实施例一
图1是本发明一实施例提供的防拆卸管接头的示意图；图2是图1的A-A向剖视图；请参照图1-图2。
本实施例提供一种防拆卸管接头，包括接管螺母100和接管螺栓200，接管螺栓200包括连接部210和装卸部220，接管螺母100套设在连接部210的外表面且与连接部210固定连接，接管螺母100和装卸部220的外表面均为光滑曲面，接管螺母100和装卸部220中至少一个的外表面上设有装卸件300，装卸件300可与配套的拆装工具连接以实现管接头的安装和拆卸。
具体的，本实施例的防拆卸管接头可用于空调中冷媒管路之间的连接，本领域技术人员清楚的是，本实施例的防拆卸管接头还可以用于其他需要设置防拆卸功能的管路之间的连接。
防拆卸管接头包括接管螺母100和接管螺栓200，接管螺母100的一端和接管螺栓200的一端均连接一条冷媒连接管，接管螺母100的另一端与接 管螺栓200的另一端固定连接，从而实现两条冷媒连接管之间的连通，以使冷媒能够在两个不同的部件中实现交替循环。
接管螺栓200包括连接部210和装卸部220，其中，连接部210位于接管螺栓200靠近接管螺母100的一侧。接管螺母100套设在连接部210的外表面且与连接部210固定连接，具体的固定连接方式可以采用螺纹连接，例如，可以在接管螺母100的内表面设有内螺纹，可以在装卸部220的外表面设有外螺纹，接管螺母100和接管螺栓200通过内螺纹和外螺纹的配合连接固定。内螺纹具体可以设置在接管螺母100内表面的螺纹段110上，螺纹段110设置在接管螺母100靠近接管螺栓200的一侧。
接管螺母200与接管螺栓200连接固定后，装卸部220位于接管螺纹200的外侧，接管螺母200的外表面和装卸部220的外表面均暴露在外界环境中。本实施例中，接管螺母100和装卸部220的外表面均为光滑曲面，从而使得已有技术中的扳手等工具无法在接管螺母100和装卸部220的外表面上找到受力面，进而无法对管接头进行安装和拆卸，从而使本实施例的管接头不易拆卸，以达到防拆卸的目的。
进一步地，为了保证管接头的正常安装和日常维护的拆卸需求，可以在接管螺母100和装卸部220中至少一个的外表面上设有装卸件300，装卸件300可与配套的拆装工具连接以实现管接头的安装和拆卸。装卸件300具体可以是设置在光滑曲面上的凹槽或凸起等结构。
本实施例的管接头在使用时，可以先将接管螺母100和接管螺栓200与对应的冷媒连接管连接固定，然后将接管螺栓200上的连接部210插入接管螺母100的内部，利用专用的安装拆卸工具对准接管螺母100和/或装卸部220外表面的装卸件300，以使安装拆卸工具能够将力传递至接管螺母100和/或装卸部220上，转动安装拆卸工具使得接管螺母100与接管螺栓200螺纹连接固定。当需要拆卸时，可以让专业的维修人员利用特定的安装拆卸工具对管接头进行拆卸。
通过上述描述可知，本实施例管接头由于需要使用专用的配套安装工具进行安装和拆卸，因此在专业人员安装固定后能够起到防止意外拆卸或恶意紧固的效果，从而降低了冷媒泄漏的风险。此外，本实施例的管接头无需设置外部防护罩等零件即可实现防拆卸，结构简单，成本低。
本实施例提供一种防拆卸管接头，包括接管螺母100和接管螺栓200，接管螺栓200包括连接部210和装卸部220，接管螺母100套设在连接部210的外表面且与连接部210固定连接，接管螺母100和装卸部220的外表面均为光滑曲面，接管螺母100和装卸部220中至少一个的外表面上设有装卸件300，装卸件300可与配套的拆装工具连接以实现管接头的安装和拆卸。通过上述设置，由于接管螺母100和装卸部220的外表面均为光滑曲面，因此采用已有技术中的扳手将无法受力，从而达到防拆卸的目的，避免误拆卸造成冷媒泄漏而带来的危害；接管螺母100和装卸部220中至少一个的外表面上设有装卸件300，装卸件300可与配套的拆装工具连接以实现管接头的安装和拆卸，由此可以保证管接头的正常安装以及日常检修维护的需求。
在一个可选地实施方式中，本实施例的装卸件300可以为设置在接管螺母100的外表面的凸起或凹槽。
在本实施方式中接管螺母100的外表面设有凸起或凹槽，装卸部220的外表面仍为光滑曲面。当需要将接管螺母100与接管螺栓200连接固定或拆卸时，可以利用专用的安装拆卸工具与接管螺母100上的凹槽或凸起相配合，以使安装拆卸工具施加的力能够传递至接管螺母100上，可以用手或其他工具将接管螺栓200夹持固定，以防止其转动，向安装拆卸工具施加作用力直至接管螺母100与接管螺栓200连接到位或完全分离。
在另一个可选地实施方式中，装卸件300为设置在装卸部220的外表面的凸起或凹槽。
在本实施方式中装卸部220的外表面设有凸起或凹槽，接管螺母100的外表面仍为光滑曲面。当需要将接管螺母100与接管螺栓200连接固定或拆 卸时，可以利用专用的安装拆卸工具与装卸部220上的凹槽或凸起相配合，以使安装拆卸工具施加的力能够传递至接管螺栓200上，可以用手或其他工具将接管螺母100夹持固定，以防止其转动，向安装拆卸工具施加作用力直至接管螺母100与接管螺栓200连接到位或完全分离。
在再一个可选地实施方式中，装卸件300包括设置在接管螺母100的外表面的凸起或凹槽以及设置在装卸部220的外表面的凸起或凹槽。
在本实施方式中接管螺母100与装卸部220的外表面均设有凸起或凹槽。当需要将接管螺母100与接管螺栓200连接固定或拆卸时，可以利用专用的安装拆卸工具分别与接管螺母100和装卸部220上的凹槽或凸起相配合，以使安装拆卸工具施加的力能够传递至接管螺栓200和装卸部220上，向接管螺母100和装卸部220上的安装拆卸工具分别施加相反的作用力直至接管螺母100与接管螺栓200连接到位或完全分离。与上述两种实施方式相比，本实施方式能够更加快速的完成接管螺母100和接管螺栓200的安装或拆卸。
进一步可选的，本实施例中的装卸件220的数量可以为多个，多个装卸件沿管接头的周向均匀分布，这样可以提高安装拆卸工具与接管螺母100或接管螺栓200的接触面积，从而更加利于安装和拆卸。
在本实施例中，上述光滑曲面可以为圆柱面、圆锥面或椭圆柱面等结构，优选地，光滑曲面可以为圆柱面，圆柱面可以保证表面与安装拆卸工具接触时，在各处的受力情况相等。
进一步地，为便于实现两条冷媒连接管的对接，提高连接后的密封性，本实施例的接管螺栓200上还设有管道连接部230，管道连接部230位于装卸部220朝向接管螺母100的一侧，管道连接部230的外表面呈锥面，且锥面的小直径端背离装卸部220；接管螺母100的内表面设有与管道连接部230相适配的锥面段120。当连接冷媒管道时，管道连接部230的小直径端可插入冷媒管道的开口端，并伸入仅冷媒管道一定的距离，从而保证了连接的密封性。

本实施例提供一种防拆卸管接头组件，包括第一冷媒连接管400、第二冷媒连接管500以及如上实施例一所述的防拆卸管接头，第一冷媒连接管400和第二冷媒连接管500通过防拆卸管接头固定连接。
具体的，第一冷媒连接管400与接管螺母100固定连接，二者的固定连接方式可以采用螺纹连接、焊接等；第二冷媒连接管500与接管螺栓200固定连接，二者的固定连接方式可以采用螺纹连接、焊接等；防拆卸管接头的具体结构以及连接方式已在上述实施例一中做出了详细描述，此处不再赘述。
通过上述设置，本实施例的防拆卸管接头组件能够起到防止意外拆卸或恶意紧固的效果，从而降低了冷媒泄漏的风险。此外，本实施例的防拆卸管接头组件无需设置外部防护罩等零件即可实现防拆卸，结构简单，成本低。
