技术领域
本公开涉及空调器技术领域，特别是涉及一种接头组件以及空调器。
背景技术
相关技术中，空调器通过公接头和母接头的对接连通实现室外机、室内机之间的高压冷媒管和低压冷媒管的连通。一般而言，公接头和母接头采用直插球套式的连接方式，公接头的外侧壁设置有一个环形凹槽，母接头在其连接腔中设置有与环形凹槽配合的锁紧件。在将公接头和母接头锁紧连接过程中，可将公接头插入至母接头的连接腔中，公接头在母接头的连接腔中轴向移动，直至环形凹槽移动到锁紧件的位置，以使锁紧件限位于锁定凹槽，从而将公接头和母接头锁紧连接。但是，在这种连接结构下，公接头和母接头锁紧连接后，二者仍能够发生相对转动，如此增加了泄露的风险。
发明内容
本公开旨在至少在一定程度上解决现有技术中的上述技术问题之一。为此，本公开的一个目的在于提供一种接头组件以及空调器，以使接头组件锁紧连接后不能相对转动，减小泄露的风险。
第一方面，本公开实施例提供了一种接头组件，包括：
第一接头，所述第一接头设置有第一端部，所述第一端部的外侧壁设置有多个沿周向间隔布置的锁定凹腔；
第二接头，所述第二接头设置有与所述第一端部相对接的第二端部，所述第二端部设置有外套件和内套件，所述内套件具有与所述第一端部配合的内侧壁，所述内套件设置有与所述锁定凹腔对应的至少一个容置孔，所述容置孔中设置有锁紧件；所述外套件套设于所述内套件的外侧，所述外套件能够相对所述内套件轴向移动且具有锁定位置和解锁位置；
当所述外套件处于锁定位置且所述锁定凹腔与所述容置孔相对应时，所述外套件将所述锁紧件限位于所述锁定凹腔中；
当所述外套件处于解锁位置时，所述外套件给所述锁紧件让位以供所述锁紧件从所述 锁定凹腔中脱出。
本公开实施例提供的接头组件至少具有如下有益技术效果：
本公开实施例，空调器的接头组件包括第一接头和第二接头，其中，第一接头在其第一端部的外侧壁设置多个沿周向间隔布置的锁定凹腔，第二接头在其第二端部的内套件设置有与所述锁定凹腔对应的容置孔，容置孔中设置有锁紧件。在第一接头的第一端部与第二接头的第二端部对接的过程中，第一端部的外侧壁和第二端部的内套件的内侧壁相互配合，当所述锁定凹腔与所述容置孔相对应时，容置孔中的锁紧件落入锁定凹腔中，并通过处于锁定位置的外套件将所述锁紧件限位于所述锁定凹腔中。如此，第一接头和第二接头处于锁定状态，锁紧件无法从锁定凹腔中脱出。本公开这种通过锁紧件与锁定凹腔配合将第一接头和第二接头位置锁定的方式，可以使第一接头和第二接头在处于锁定状态时无法发生相对转动，进而减小接头组件泄露的风险。
根据本公开一些实施例的接头组件，所述第一接头的外侧壁设置有至少一个凸台，所述凸台环绕所述第一接头的外周设置，所述凸台为外多边形结构，在将第一接头安装至空调器的室外机或者室内机时，可将与凸台形状适配的套筒套装于第一接头外，然后将套筒与电动安装设备连接，进而实现电动化安装。
根据本公开一些实施例的接头组件，所述内套件的内侧设置有阀套，所述阀套能够在所述第一接头的驱动下相对所述内套件轴向移动；所述阀套处于未被所述第一接头驱动的初始位置时，所述阀套的外端面相对所述内套件的外端面向内凹陷，凹陷的位置能够限定出第一接头在第二接头上的对接位置，从而使安装人员可方便地将第一接头与第二接头对接安装。
根据本公开一些实施例的接头组件，所述内套件的外端面设置有内倒角，通过内倒角可方便安装人员快速找准第一接头和第二接头的对接位置，进而将第一接头安装至第二接头。
根据本公开一些实施例的接头组件，所述外套件在远离所述第一接头的一端连接有第一弹簧件，所述外套件能够在所述第一弹簧件的驱动下从所述解锁位置复位至所述锁定位置。

第三方面，本公开实施例还提供了一种空调器，所述空调器包括空调室外机和空调室内机，所述空调室外机和空调室内机之间设置有如上第二方面所述的空调用连接管。
本公开实施例的空调器至少具有如下有益技术效果：
空调器使用的空调用连接管包括接头组件，接头组件包括第一接头和第二接头，其中，第一接头在其第一端部的外侧壁设置多个沿周向间隔布置的锁定凹腔，第二接头在其第二端部的内套件设置有与所述锁定凹腔对应的容置孔，容置孔中设置有锁紧件。在第一接头的第一端部与第二接头的第二端部对接的过程中，第一端部的外侧壁和第二端部的内套件的内侧壁相互配合，当所述锁定凹腔与所述容置孔相对应时，容置孔中的锁紧件落入锁定凹腔中，并通过处于锁定位置的外套件将所述锁紧件限位于所述锁定凹腔中。如此，第一接头和第二接头处于锁定状态，锁紧件无法从锁定凹腔中脱出。本公开这种通过锁紧件与锁定凹腔配合将第一接头和第二接头位置锁定的方式，可以使第一接头和第二接头在处于锁定状态时无法发生相对转动，进而减小接头组件泄露的风险。

还需说明的是，下面所描述的本公开各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
下面结合附图，对本公开实施例提供的接头组件以及空调器进行详细描述。
为便于更好理解本公开实施例提供的接头组件，下面首先对本公开提供的接头组件的应用场景进行说明。
对于分体式的空调器而言，通常包括安装于室内的室内机和安装于室外的室外机。室内机与室外机通过冷媒(也可称为制冷剂、换热媒)进行热交换。为了使冷媒在室内机与室外机之间循环流动，需要在室内机和室外机之间设置冷媒连接管。一般来说，室内机和室外机之间的冷媒连接管设置为两根，分别为高压冷媒连接管和低压冷媒连接管，其中，高压冷媒连接管用于传送高压的气态冷媒，低压冷媒连接管用于传送低压的液态冷媒。无论对于高压冷媒连接管还是低压冷媒连接管，在实现与室外机进行连接时，均是通过接头组件连接至室外机的截止阀。本公开实施例提供的接头组件，即是应用于空调器中，用于实现室内机和室外机之间的冷媒连接管的连通。
相关技术中，接头组件通常包括公接头和母接头，且公接头和母接头通常采用直插球套式的连接方式。一般而言，公接头的外侧壁设置有一个环形凹槽，母接头在其连接腔中设置有与环形凹槽配合的锁紧件。在将公接头和母接头锁紧连接过程中，可将公接头插入至母接头的连接腔中，公接头在母接头的连接腔中轴向移动，直至环形凹槽移动到锁紧件的位置，以使锁紧件限位于锁定凹槽，从而将公接头和母接头锁紧连接。但是，在这种连接结构下，公接头和母接头锁紧连接后，二者只是在轴向上位置固定，仍能够发生相对转动，如此会增加泄露的风险。
基于此，本公开实施例目的在于提供一种接头组件以及空调器，以使接头组件锁紧连接后不能相对转动，减小泄露的风险。
请参见图1，图1示出了本公开实施例提供的一种接头组件的结构示意图。如图1所示，本公开实施例的接头组件包括第一接头10和与第一接头10对接的第二接头20。这里，第一接头10也可称作公接头，第二接头20也可称作母接头。应了解的是，本公开实施例描述的接头组件还可以称为快速接头。
可以理解的是，本公开实施例提供的接头组件可应用于空调用连接管中，该空调用连接管用于连接空调室外机和空调室内机。具体地，空调用连接管包括冷媒管(通常为柔性管体)和接头组件，其中，接头组件的数量为两个，分别设置在冷媒管的两端。接头组件的第二接头20与冷媒管连接，一个接头组件的第一接头10连接于空调室外机，另一个接头组件的第一接头10连接于空调室内机。也就是说，空调室外机和空调室内机的连接关系为：空调室外机-第一接头10-第二接头20-冷媒管-第二接头20-第一接头10-空调室内机。
请参见图2，图2示出了本公开实施例提供的第一接头10的结构示意图。如图2所示，本公开实施例的第一接头10具有第一端部，这里，第一端部可理解为第一接头10用于与第二接头20连接的端部。本公开实施例在第一端部的外侧壁设置有锁定凹腔11。这里，锁定凹腔11的数量为多个，多个锁定凹腔11沿第一端部的周向间隔分布。
在一个具体的示例中，锁定凹腔11的数量为4个，4个锁定凹腔11以90度间隔、周向均匀地分布在第一端部的外侧壁。在另一个具体的示例中，锁定凹腔11的数量为6个，6个锁定凹腔11以60度间隔、周向均匀地分布在第一端部的外侧壁。在又一个具体的示例中，锁定凹腔11的数量为8个，8个锁定凹腔11以45度间隔、周向均匀地分布在第一端部的外侧壁。可以理解的是，本领域技术人员可根据实际需要适应性地调整锁定凹腔11的数量和分布间隔，本公开实施例对此不作过多限制。
示例性的，锁定凹腔11的具体可以为锥形腔体或者半球形腔体，本公开实施例对锁定凹腔11的具体形状不作过多限制。
请参见图3，图3示出了本公开实施例的接头组件的剖面结构示意图。如图3所示，本公开实施例的第二接头20具有第二端部，这里，第二端部可理解为用于与第一接头10(第一端部)连接的端部，即第二端部与所述第一端部相对接。
具体地，所述第二端部设置有外套件22和内套件23。其中，所述外套件22套设于所述内套件23的外侧。所述内套件23设置有与所述锁定凹腔11对应的容置孔，所述容置孔中设置有锁紧件21。
可以理解的是，容置孔的数量可以是一个或者多个。具体实现时，容置孔的数量可以与锁定凹腔11的数量相等或者不相等。
在一个具体的示例中，内套件23上设置有多个沿内套件23的周向间隔分布的容置孔，而且容置孔的数量与第一接头10上的锁定凹腔11的数量相等，多个锁定凹腔11与多个容置孔一一对应。示例性的，第一接头10设置有8个锁定凹腔11，8个锁定凹腔11以45度间隔、周向均匀地分布在第一端部的外侧壁，对应地，内套件23上设置有8个容置孔， 8个容置孔以45度间隔、周向均匀地分布在内套件23上。
在另一个具体的示例中，内套件23上设置有多个沿内套件23的周向间隔分布的容置孔，容置孔的数量与第一接头10上的锁定凹腔11的数量不相等。示例性的，第一接头10设置有8个锁定凹腔11，8个锁定凹腔11以45度间隔、周向均匀地分布在第一端部的外侧壁，第二接头20的内套件23上设置有2个容置孔，2个容置孔以90度间隔、周向均匀地分布在内套件23上。
示例性的，本公开实施例描述的锁紧件21可以是钢球，当然，锁紧件21还可以是其他形式的部件，本公开实施例对锁紧件21的具体形式不作过多限制。
可以理解的是，内套件23具有与所述第一端部配合的内侧壁，即：当第一接头10的第一端部插入至第二接头20的第二端部时，第一端部的外侧壁与内套件23的内侧壁相对，当第一端部的锁定凹腔11运动至与第二端部的容置孔相对应时，锁紧件21落入锁定凹腔11之中。
可以理解的是，容置孔为通孔，即容置孔连通内套件23的内侧和外侧，这里，内套件23的内侧指内套件23与第一端部配合的一侧，内套件23的外侧指内套件23与外套件22配合的一侧。
可以理解的是，外套件22能够相对所述内套件23轴向移动，且具有锁定位置和解锁位置。当所述外套件22处于锁定位置且所述锁定凹腔11与所述容置孔相对应时，所述外套件22将所述锁紧件21限位于所述锁定凹腔11中。当所述外套件22处于解锁位置时，所述外套件22给所述锁紧件21让位以供所述锁紧件21从所述锁定凹腔11中脱出。
可以理解的是，在图3中，外套件22处于锁定位置，外套件22的侧壁将锁紧件21(钢球)限位在锁定凹腔11之中。作为示例，外套件22在其靠近第一接头10的端口处设置有避让位，在需要将第一接头10和第二接头20分离时，可以推动外套件22以使外套件22沿内套件23外侧壁朝远离第一接头10的方向轴向移动，使得外套件22处于解锁位置，此时外套件22的避让位与容置孔相对应，该避让位可以给所述锁紧件21让位，以供所述锁紧件21从所述锁定凹腔11中脱出，如此，即可顺利将第一接头10从第二接头20中取出。本领域技术人员应能理解，外套件22的避让位还可以设置成其它形式，以使外套件22以周向运动的方式从锁定位置切换至解锁位置，本公开实施例对外套件22的具体结构不作过多限制。
如图3所示，外套件22在远离所述第一接头10的一端连接有第一弹簧件26，所述外套件22能够在所述第一弹簧件26的驱动下从所述解锁位置复位至所述锁定位置。当施加至外套件22以使外套件22从锁定位置切换至解锁位置的推力消失后，外套件22能够在 所述第一弹簧件26的驱动下从所述解锁位置复位至所述锁定位置。
可以理解的是，在本公开实施例的方案中，第一接头10在其第一端部的外侧壁设置多个沿周向间隔布置的锁定凹腔11，第二接头20在其第二端部的内套件23设置有与所述锁定凹腔11对应的容置孔，容置孔中设置有锁紧件21。在第一接头10的第一端部与第二接头20的第二端部对接的过程中，第一端部的外侧壁和第二端部的内套件23的内侧壁相互配合，当所述锁定凹腔11与所述容置孔相对应时，容置孔中的锁紧件21落入锁定凹腔11中，并通过处于锁定位置的外套件22将所述锁紧件21限位于所述锁定凹腔11中。如此，第一接头10和第二接头20处于锁定状态，锁紧件21无法从锁定凹腔11中脱出。本公开这种通过锁紧件21与锁定凹腔11配合将第一接头10和第二接头20位置锁定的方式，可以使第一接头10和第二接头20在处于锁定状态时无法发生相对转动，进而减小接头组件泄露的风险。
请参见图4a和图4b，图4a和图4b示出了本公开实施例提供的另一种第一接头10。相比图3所示实施例中的第一接头10，图4a和图4b所示实施例中的第一接头10的外侧壁上还设置有至少一个凸台12，所述凸台12环绕所述第一接头10的外周设置。具体地，所述凸台12为外多边形结构。在将第一接头10安装至空调室外机或者空调室内机时，可使用与凸台12形状适配的套筒进行安装，具体地，将套筒套装于第一接头10外以卡住第一接头10，然后将套筒连接于电动安装设备，进而利用电动安装设备实现电动化安装，提高了安装效率。
示例性的，凸台12的外边沿形状可以是六边形结构、八边形结构或者其它的多边形结构。对应的，安装所采用的套筒应具有内六角形状、内八角形状或者其它内多角形状的结构。
如图3所示，本公开实施例的第二接头20中还可以包括阀套24，具体地，阀套24设置在内套件23的内侧，当第一接头10插入至第二接头20时，所述阀套24能够在所述第一接头10的驱动下相对所述内套件23轴向移动。可以理解，阀套24在第一接头10的顶压下，可将第二接头20的内腔打开，使得第一接头10的内腔和第二接头20的内腔相连通。
所述阀套24在远离所述第一接头10的一端连接有第二弹簧件27，当第一接头10从第二接头20中分离时，所述阀套24能够在所述第二弹簧件27的驱动下复位至初始位置。
请参见图5a-图5f，图5a-图5f示出了本公开实施例的第二接头20的部分结构(主要示出了外套件22、内套件23和阀套24)示意图。其中，图5a为立体结构示意图，图5b为主视图，图5c为侧视图，图5d为图5b中A-A向的截面示意图，图5e为图5c中B-B 向的截面示意图，图5f为图5d中D处的放大结构示意图。
如图5a-图5f所示，当阀套24处于初始位置(即图5a-图5f所示的未被所述第一接头10驱动下的状态)时，阀套24的外端面相对内套件23的外端面向内凹陷，从而在第二接头20的端面处形成一凹陷结构，而该凹陷结构能够限定出第一接头10在第二接头20上的对接位置，从而使安装人员可基于该凹陷结构、快速方便地将第一接头10插入至第二接头20中，实现第一接头10和第二接头20的快速对接。
请参见图5f，内套件23的外端面还设置有内倒角25，通过内倒角25的导向，可进一步方便安装人员将第一接头10与第二接头20进行对接。如果没有内倒角25，安装人员往往需要通过视线观察第一接头的端面和第二接头对应的端面，视线观察到两个端面的位置对准后才能实现对接，而采用带内倒角的设计后，只需大致对准就能确定好第一接头10和第二接头20的对接位置，更快捷高效。
本公开实施例还提供了一种空调用连接管，所述空调用连接管包括冷媒管和如上任意实施例所述的接头组件；所述接头组件设置有两个，分别连接于所述冷媒管的两侧。
本公开实施例的空调用连接管的接头组件包括第一接头10和第二接头20，其中，第一接头10在其第一端部的外侧壁设置多个沿周向间隔布置的锁定凹腔11，第二接头20在其第二端部的内套件23设置有与所述锁定凹腔11对应的容置孔，容置孔中设置有锁紧件21。在第一接头10的第一端部与第二接头20的第二端部对接的过程中，第一端部的外侧壁和第二端部的内套件23的内侧壁相互配合，当所述锁定凹腔11与所述容置孔相对应时，容置孔中的锁紧件21落入锁定凹腔11中，并通过处于锁定位置的外套件22将所述锁紧件21限位于所述锁定凹腔11中。如此，第一接头10和第二接头20处于锁定状态，锁紧件21无法从锁定凹腔11中脱出。本公开这种通过锁紧件21与锁定凹腔11配合将第一接头10和第二接头20位置锁定的方式，可以使第一接头10和第二接头20在处于锁定状态时无法发生相对转动，进而减小接头组件泄露的风险。
本公开实施例还提供了一种空调器，所述空调器包括空调室外机和空调室内机，所述空调室外机和空调室内机之间设置有如上任意实施例所述的空调用连接管。
本公开实施例的空调器所使用的空调用连接管包括接头组件，接头组件包括第一接头10和第二接头20，其中，第一接头10在其第一端部的外侧壁设置多个沿周向间隔布置的锁定凹腔11，第二接头20在其第二端部的内套件23设置有与所述锁定凹腔11对应的容置孔，容置孔中设置有锁紧件21。在第一接头10的第一端部与第二接头20的第二端部对接的过程中，第一端部的外侧壁和第二端部的内套件23的内侧壁相互配合，当所述锁定凹腔11与所述容置孔相对应时，容置孔中的锁紧件21落入锁定凹腔11中，并通过处于 锁定位置的外套件22将所述锁紧件21限位于所述锁定凹腔11中。如此，第一接头10和第二接头20处于锁定状态，锁紧件21无法从锁定凹腔11中脱出。本公开这种通过锁紧件21与锁定凹腔11配合将第一接头10和第二接头20位置锁定的方式，可以使第一接头10和第二接头20在处于锁定状态时无法发生相对转动，进而减小接头组件泄露的风险。
以上是对本公开的较佳实施进行了具体说明，但本公开并不局限于上述实施方式，熟悉本领域的技术人员在不违背本公开精神的前提下还可作出种种的等同变形或替换，这些等同的变形或替换均包含在本公开权利要求所限定的范围内。
