在一个实施例中，所述受力棱边平行于所述防拆连接件的中心轴线。
如此设置，普通扳手卡在受力棱边上，从受力面朝向防拆凸块的外周面拧紧防拆连接件时，普通扳手的施力方向与防拆连接件的中心轴线垂直，此时，普通扳手对受力棱边提供的力与防拆连接件的中心轴线的距离最大。由物理学常识可知，此时，普通扳手对受力棱边提供的力与防拆连接件的中心轴线形成的力矩最大，拧紧效果最好。
在一个实施例中，所述受力面为平面，且所述受力面平行于所述防拆连接件的轴向平面。
如此设置，受力面能够与接头扳手对应的配合面紧密接触，而且接头扳手作用于受力面的力垂直于通孔的轴向。在使用螺母扳手与接头扳手连接防拆连接件与固定件时，接头 扳手对防拆连接件提供沿周向的抵持力矩，而不会产生沿防拆连接件轴向的分力，从而快速、省力地将防拆连接件与固定件旋紧。
在一个实施例中，所述受力面与所述防拆连接件的外周面相交处形成交线，且所述受力面垂直于所述防拆连接件外周面位于所述交线处的切平面。
如此设置，受力面垂直于柱体位于交线处的切平面，有利于防拆连接件的拧紧操作。
在一个实施例中，所述泄力面为斜面或弧形面或内凹曲面。
如此设置，泄力面设置为斜面或弧形面或内凹曲面，泄力面的形状更加平滑，能够更进一步减小泄力面与接头扳手间的摩擦系数，从而避免接头扳手与泄力面间的相对移动卡涩或卡滞，并且便于外部工具上升，使外部工具无法受力，无法反向松动防拆连接件，以实现防拆连接件的防拆卸功能。
在一个实施例中，所述泄力面与所述防拆连接件的外周面平滑衔接。
如此设置，外部工具无法通过卡在泄力面与防拆连接件的外周面之间而拧松防拆连接件。进一步提高了防拆连接件泄力面的泄力的效率，使得防拆连接件更加难以被拆卸。
在一个实施例中，所述防拆连接件还包括底座，所述底座位于所述防拆连接件的一端或外周壁；所述底座包括相对靠近所述防拆凸块的第一端面，所述第一端面与所述泄力面间平滑过渡。
如此设置，底座的设置提高了防拆凸块与防拆连接件的连接牢固程度。第一端面与泄力面形成的光滑表面可以显著降低与接头扳手间的摩擦系数，防止泄力面出现明显转折或凸起，能够避免防拆连接件与泄力面间产生抵持力或静摩擦力，从而影响防拆连接件的防拆卸效果。
在一个实施例中，防拆连接件一端设有外螺纹并形成第一螺纹部，所述防拆连接件包括柱体，所述第一螺纹部设于所述柱体的一端，所述防拆凸块设于所述柱体远离所述第一螺纹部的另一端，所述底座连接于所述防拆凸块背离所述第一螺纹部的一侧；或者，所述防拆连接件内设置有通孔，所述通孔内具有内螺纹并形成第一螺纹部。
如此设置，能够实现防拆连接件与固定件之间的螺纹连接。
在一个实施例中，所述防拆凸块的数量为多个，多个所述防拆凸块沿所述防拆连接件的周向分布，所述受力面和所述泄力面沿着所述防拆连接件的周向交替分布。
如此设置，提高了外部工具作用于防拆连接件的受力面的数量，使得外部工具拧紧防拆连接件时，有更多的着力点，提高了外部工具的使用稳定性。并且，泄力面的数量也相应的增加，提高了防拆连接件对于外部工具的泄力效率。
在一个实施例中，所述防拆凸块包括以防拆连接件的轴线为中心旋转对称的第一凸起和第二凸起。
如此设置，第一凸起的受力面和第二凸起的受力面位于同一平面上，有利于外部工具同时作用于第一凸起和第二凸起，对防拆连接件进行拧紧操作。
在一个实施例中，所述防拆凸块的最大外径为所述防拆连接件的直径的最大值。
如此设置，技术人员可以使用外部工具夹持防拆凸块的外周面，从而强制拆卸防拆连接件与固定件，而不会损坏防拆凸块的泄力面或受力面，因而不会影响防拆连接件的多次使用。
在一个实施例中，所述第一凸起的所述受力棱边与所述第二凸起的所述受力棱边共同形成所述防拆连接件外径的最大值。
如此设置，便于普通扳手与受力棱边接触并卡位，操作人员能够便捷地使用普通扳手安装防拆连接件。
本申请还提供一种防拆连接组件，包括固定件和上述防拆连接件，所述防拆连接件和所述固定件两者中的一者包括具有内螺纹孔的第一螺纹部，另一者包括设有外螺纹的第二螺纹部，所述第一螺纹部与所述第二螺纹部螺纹配合连接。
本申请提供的防拆连接件组件，具有防止拆卸的功能。作业人员只能通过与固定件配 合的螺母扳手以及与防拆连接件配合的接头扳手将二者旋紧，而无法旋松。
在一个实施例中，所述防拆凸块位于所述防拆连接件的一端，所述防拆连接件的另一端设有外螺纹并形成所述第一螺纹部，所述泄力面朝向所述第一螺纹部；所述固定件设有装配孔，所述装配孔内设有内螺纹，所述内螺纹与所述防拆连接件的所述第一螺纹部相配合。
在一个实施例中，所述防拆连接件内开设有通孔，所述通孔具有内螺纹并形成所述第一螺纹部；所述固定件的端部沿轴向向外突出形成具有外螺纹的所述第二螺纹部，所述固定件通过所述第二螺纹部伸入通孔并螺纹连接于所述防拆连接件。
如此设置，防拆连接件和固定件之间形成了更加稳固可靠的螺纹连接。
本申请还提供一种空调设备，包括第一管体、第二管体以及上述的防拆连接组件，所述第一管体及所述第二管体分别与所述防拆连接件及所述固定件连接。
如此设置，大大降低了空调设备的装配复杂程度，提高了空调设备的装配效率。
在一个实施例中，所述第一管体固设于所述防拆连接件，所述第二管体的一端被夹紧固定于所述防拆连接件和所述固定件之间。
如此设置，大大降低了空调设备的装配复杂程度，提高了空调设备的装配效率。
在一个实施例中，所述防拆连接件端部外壁设有第一锥形面，所述固定件装配孔内对应设有第二锥形面；所述第二管体一端设有锥形夹持部，所述锥形夹持部被夹紧固定于所述第一锥形面和所述第二锥形面之间。
如此设置，增大了锥形夹持部和防拆连接件以及锥形夹持部和固定件的接触面积，有利于提高空调设备的装配稳定性。
在一个实施例中，所述防拆连接件或所述固定件上设置有定位段，所述定位段与所述第一管体或所述第二管体其中之一抵接并定位所述第一管体或所述第二管体。
如此设置，定位段的内壁面可以与第一管体或第二管体其中之一的外壁面抵接，从而限制第一管体或第二管体在通孔内移动，防止其从通孔中滑出。
在一个实施例中，所述定位段设有锥形定位面，所述第一管体或所述第二管体的端部设有扩口部，所述锥形定位面与所述扩口部的外壁抵接。
如此设置，能够进一步保证第一管体或第二管体相对于防拆连接件或固定件之间的同轴度，第一管体或第二管体的定位效果更加可靠，不易发生晃动；此外，定位段能够贴合于扩口部的外壁，使得防拆连接件组件具有更好的密封效果，防止冷媒从通孔内渗出泄露。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
本申请提供一种防拆连接件100，设置于分体式空调设备的室内机，用于连接蒸发器与连接管。可以理解的是，在其他实施方式中，防拆连接件100也可以用于其他类型的防拆管体的连接场合。
现有的分体式空调设备室内机要求使用不可拆卸的接头，以保证室内机内部的密封性，防止误拆导致的冷媒泄露。通常采用单接头与六角螺母配合的方式连接蒸发器与连接管，或者采用焊接管路与单接头的方式，实现防拆功能。然而单接头与六角螺母间容易松脱，二者连接不具有防拆卸功能；而通过焊接单接头与管路实现防拆卸，成本较高，操作过程复杂。
请参阅图1至图3，鉴于此，本申请提供的防拆连接件100的外周壁设有防拆凸块20，防拆凸块20具有受力面21以及泄力面22，受力面21和泄力面22防拆凸块20沿着防拆连接件100的周向设置于防拆凸块20的两侧；受力面21用于供外部工具安装防拆连接件100，泄力面22使得外部工具拆卸防拆连接件100时，防拆连接件100沿防拆连接件100的轴向推离外部工具。
请一并参阅图4至图7，在其中一个实施例中，防拆连接件100为防拆接头，防拆连接件100接头大致呈管状，内部开设有通孔11，以供第一管体310伸入。防拆接头配合固定件使用，固定件内也开设有通孔11，以供第二管体320伸入。防拆接头与固定件之间螺纹连接。可以理解，在其他实施例中，防拆连接件100也可以是防拆螺母，甚至固定件及管接头均设置有防拆结构。
具体地，防拆连接件100包括柱体10，防拆凸块20由防拆连接件100柱体10的外周壁沿远离轴线的方向延伸、突出形成。如此设置，防拆凸块20在防拆连接件100上的设置更加牢固。
在一个实施例中，防拆凸块20的外周面与受力面21相交形成一受力棱边211，受力棱边211用于供外部工具卡位并施加扭力。
在实际应用中，防拆连接件100与固定件210螺纹连接固定件；外部工具可以是接头扳手或螺母扳手，还可以是普通扳手，例如活络扳手、呆扳手。
例如，外部工具包括与防拆凸块20以及防拆连接件100的外周壁配合的接头扳手，还包括用于夹紧并固定固定件210的螺母扳手；伸入接头扳手内的防拆连接件100的外周壁为回转面，便于作业人员转动接头扳手从而对防拆连接件100施加旋紧力矩；当接头扳手套设防拆连接件100时，可转动接头扳手使其接触受力面21或者泄力面22。接头扳手能够对防拆连接件100产生垂直于其径向的力或分力，即作用于受力面21的抵持力，因而二者间相互抵持；泄力面22能够对接头扳手产生沿防拆连接件100轴向的分力，进一 步转动接头扳手，由于接头扳手与泄力面22间不足以产生较大的抵持力或静摩擦力，接头扳手将相对于泄力面22移动，防拆凸块20通过泄力面22，将接头扳手沿防拆连接件100的轴向推离防拆连接件100。
当然，对防拆连接件100施加外力的外部工具也可以是普通扳手或螺母扳手。当普通扳手或螺母扳手从受力面21朝向防拆凸块20的外周面拧防拆连接件100时，普通扳手或螺母扳手能够卡在受力棱边211靠近受力面21的一侧，此时，普通扳手或螺母扳手能够拧动防拆连接件100，从而将防拆连接件100拧紧；当普通扳手或螺母扳手从防拆凸块20的外周面朝向受力面21拧防拆连接件100时，普通扳手或螺母扳手的施力方向与防拆凸块20的外周面在受力棱边211处的切平面平行，因此，普通扳手或螺母扳手无法对防拆凸块20进行施力，也即，普通扳手或螺母扳手将防拆连接件100拧松，从而达到了防拆效果。
当选用接头扳手安装防拆连接件100时，防拆连接件100与固定件210的安装过程为：作业人员首先将固定件210与防拆连接件100螺纹连接，并使用螺母扳手夹紧固定件210，然后将防拆连接件100与接头扳手配合，沿紧固方向，即接头扳手与受力面21贴合且抵持的方向，转动接头扳手与螺母扳手中的一者，此时螺母扳手对固定件210施加紧固力矩，接头扳手对受力面21产生了抵持力，进而接头扳手对防拆连接件100施加了与上述紧固力矩方向相反的旋紧力矩。在紧固力矩与旋紧力矩的共同作用下，固定件210与防拆连接件100通过螺纹配合旋紧；保持螺母扳手与固定件210间夹紧状态不变，沿相反方向转动接头扳手，使其与泄力面22接触，此时接头扳手无法抵持在泄力面22上，将会沿着泄力面22滑移，导致接头扳手无法对防拆连接件100产生与旋紧力矩相反的旋松力矩。最终接头扳手被防拆凸块20泄力，即接头扳手只能沿紧固方向转动，通过抵持于受力面21对防拆连接件100产生旋紧力矩，从而使防拆连接件100与固定件210通过螺纹紧固连接，而无法沿相反的方向对防拆连接件100施加旋松力矩，以使防拆连接件100与固定件210旋松并分离，因而无法拆卸防拆连接件100与固定件210。
当选用普通扳手或螺母扳手安装防拆连接件100时，防拆连接件100与固定件210的安装过程与上述过程大致相同，其区别仅在于：普通扳手或螺母扳手能够卡在受力棱边211上施加旋紧力矩，而无法通过受力棱边211施加旋松力矩。
本申请提供的防拆连接件100具有防拆卸功能，可以与固定件210固定连接并配套使用。在使用接头扳手、螺母扳手或普通扳手安装防拆连接件100与固定件210的过程中，扳手只能沿紧固方向通过受力面21对防拆连接件100产生旋紧力矩，从而旋紧固定件210与防拆连接件100；而无法沿相反方向对防拆连接件100产生旋松力矩从而拆卸固定件210与防拆连接件100；此外，防拆凸块20设置在防拆连接件100的外周壁，更方便作业人员将接头扳手快速套设在防拆连接件100的外周壁，特别是便于套设尺寸较小的防拆连接件100；以及便于作业人员将普通扳手或螺母扳手快速卡接于受力棱边211，提高了作业便利性。另外，防拆凸块20设置在防拆连接件100的外周壁上，增大了扳手对防拆连接件100的旋紧力矩的力臂或力偶臂长度，如此作业人员可以更加省力地完成固定件210与防拆连接件100的旋紧。
可选的，在其中一个实施方式中，防拆连接件100的外周壁呈圆锥台面状，沿接头扳手靠近并套设防拆连接件100的方向，防拆连接件100的外径增大；可以理解，在其他实施方式中，防拆连接件100的外周壁形状也可以是其他类型的回转面，例如圆柱面或者圆柱面与圆锥台面的结合。
在本实施例中，紧固方向为顺时针方向，泄力面22的旋向为逆时针方向。在其他实施例中，紧固方向也可以是逆时针方向，泄力面22的旋向为顺时针方向。
在一个实施例中，受力棱边211平行于防拆连接件100的中心轴线。
如此设置，普通扳手卡在受力棱边211上，从受力面21朝向防拆凸块20的外周面拧紧防拆连接件100时，普通扳手的施力方向与防拆连接件100的中心轴线垂直，此时，普通扳手对受力棱边211提供的力与防拆连接件100的中心轴线的距离最大。由物理学常识 可知，此时，普通扳手对受力棱边211提供的力与防拆连接件100的中心轴线形成的力矩最大，拧紧效果最好。
在其中一个实施方式中，受力面21为平面，且受力面21平行于防拆连接件100的轴向平面。
如此设置，受力面21能够与接头扳手对应的配合面紧密接触，而且接头扳手作用于受力面21的力垂直于通孔11的轴向。在使用螺母扳手与接头扳手连接防拆连接件100与固定件210时，接头扳手对防拆连接件100提供沿周向的抵持力矩，而不会产生沿防拆连接件100轴向的分力，从而快速、省力地将防拆连接件100与固定件210旋紧。
可以理解的是，受力面21也可以是曲面，受力面21垂直于通孔11的径向方向，只要接头扳手能够与防拆连接件100配合，并且接头扳手能够对受力面21产生垂直于防拆连接件100径向的抵持力或抵持分力，从而产生对防拆连接件100的旋紧力矩即可。
在一个实施例中，受力面21与柱体10的外周面相交处形成交线212，且受力面21垂直于柱体10位于交线212处的切平面，泄力面22为斜面或弧形面或内凹曲面。外部工具的施力方向垂直于受力面21，而受力面21垂直于柱体10位于交线212处的切平面，则外部工具的施力方向平行于上述切平面。由常识可知，交线212处的切平面垂直于柱体10在交线212处的曲率半径，因而外部工具的施力方向垂直于柱体10在交线212处的曲率半径。而由物理学公式可知，力矩M、力臂的长度L、力的大小F以及力与力臂之间的夹角A的关系为：M＝L*F*sinA。当力垂直于力臂时，力矩最大，也即，外部工具的施力方向垂直于柱体10在交线212处的曲率半径时，外部工具对防拆连接件100施加的力矩最大，有利于防拆连接件100的拧紧操作。泄力面22设置为斜面或弧形面，泄力面22的形状更加平滑，能够更进一步减小泄力面22与接头扳手间的摩擦系数，从而避免接头扳手与泄力面22间的相对移动卡涩或卡滞，并且便于外部工具上升，使外部工具无法受力，无法反向松动防拆连接件100，以实现防拆连接件100的防拆卸功能。
可选的，在其中一个实施方式中，泄力面22为以防拆连接件100轴线为中心线的螺旋面。从防拆连接件100的侧部方向观察，泄力面22沿接头扳手套设防拆连接件100的方向内凹。
如此设置，泄力面22的形状更加平滑，能够更进一步减小泄力面22与接头扳手间的摩擦系数，从而避免接头扳手与泄力面22间的相对移动卡涩或卡滞，更好地实现防拆连接件100的防拆卸功能。
可以理解的是，泄力面22也可以沿防拆连接件100的轴线方向外凸设置，对于沿防拆连接件100轴线方向外凸设置的泄力面22，本说明书不再赘述。
在一个实施例中，泄力面22与防拆连接件100的外周面平滑衔接。如此设置，外部工具无法通过卡在泄力面22与防拆连接件100的外周面之间而拧松防拆连接件100。进一步提高了防拆连接件100泄力面22的泄力的效率，使得防拆连接件100更加难以被拆卸。
在一个实施例中，防拆连接件100还包括底座40，底座40位于防拆连接件100的一端或外周壁；底座40包括相对靠近防拆凸块20的第一端面，第一端面与泄力面22间平滑过渡。
如此设置，底座40的设置提高了防拆凸块20与防拆连接件100的连接牢固程度。第一端面与泄力面22形成的光滑表面可以显著降低与接头扳手间的摩擦系数，防止泄力面22出现明显转折或凸起，能够避免防拆连接件100与泄力面22间产生抵持力或静摩擦力，从而影响防拆连接件100的防拆卸效果。
在其中一个实施方式中，底座40位于防拆连接件100的一端或外周壁，底座40能够止挡外部工具，用于限制外部工具套设防拆连接件100的深度。
具体地，在本实施方式中，底座40能够止挡接头扳手套设防拆连接件100的深度。
如此设置，底座40能够限制接头扳手进一步套设防拆连接件100，防止接头扳手与固定件210或者其他重要的外部元件碰撞干涉，造成不必要的损坏；此外，底座40可以使 接头扳手与防拆凸块20配合的部位保持与防拆连接件100具有最大的配合面积，因而在旋紧防拆连接件100与固定件210的过程中更加可靠，防止二者滑脱。
在另一个实施例中，底座40为设置在防拆连接件100端部的圆台结构，底座40的外径大于防拆连接件100的外周壁的外径。外部工具从防拆连接件100相对远离底座40的一端套设于防拆连接件100的外周壁，第一端面止挡于外部工具的端部；泄力面22沿防拆连接件100的轴线方向内凹，因而泄力面22与第一端面共同形成了没有转折或凸起的光滑表面。
如此设置，防拆连接件100的防拆卸效果更加突出，第一端面与泄力面22形成的光滑表面可以显著降低与接头扳手间的摩擦系数，防止泄力面22出现明显转折或凸起，能够避免防拆连接件100与泄力面22间产生抵持力或静摩擦力，从而影响防拆连接件100的防拆卸效果。
在另一个实施方式中，防拆凸块20的最大外径为防拆连接件100的直径的最大值。
如此设置，技术人员可以使用外部工具夹持防拆凸块20的外周面，从而强制拆卸防拆连接件100与固定件210，而不会损坏防拆凸块20的泄力面22或受力面21，因而不会影响防拆连接件100的多次使用。
进一步的，第一凸起23的受力棱边211与第二凸起24的受力棱边211共同形成防拆连接件100外径的最大值。
如此设置，便于普通扳手与受力棱边211接触并卡位，操作人员能够便捷地使用普通扳手安装防拆连接件100。
在一个实施例中，防拆凸块20的数量为多个，多个防拆凸块20沿防拆连接件100的周向分布，受力面21和泄力面22沿着防拆连接件100的周向交替分布。
如此设置，提高了外部工具作用于防拆连接件100的受力面21的数量，使得外部工具拧紧防拆连接件100时，有更多的着力点，提高了外部工具的使用稳定性。并且，泄力面22的数量也相应的增加，提高了防拆连接件100对于外部工具的泄力效率。
在一个实施例中，防拆凸块20包括以防拆连接件100的轴线为中心旋转对称的第一凸起23和第二凸起24。
如此设置，第一凸起23的受力面21和第二凸起24的受力面21位于同一平面上，有利于外部工具同时作用于第一凸起23和第二凸起24，对防拆连接件100进行拧紧操作。
在本申请的一个实施方式中，防拆凸块20的数量至少为两个，至少两个防拆凸块20沿防拆连接件100的周向均匀分布于防拆连接件100的外周壁。
如此设置，单个防拆凸块20因接头扳手打滑等原因损坏时，接头扳手可以与另一个防拆凸块20配合，不影响固定件210与防拆连接件100的紧固安装。
另一方面，多个防拆凸块20具有多个受力面21，这增加了接头扳手与受力面21的接触面积。接头扳手能够更稳固地抵持在受力面21上，降低接头扳手与防拆连接件100滑脱的风险；也进而减小了每个防拆凸块20所受到的抵持力，从而减小每个防拆凸块20靠近防拆连接件100外周壁的根部位置的应力，最终降低了在对防拆连接件100与固定件210分别施加较大的旋紧力矩与紧固力矩时，防拆凸块20断裂或被压溃的风险。
在其中一个实施例中，如图1-7所示，防拆连接件100内设置有通孔11，通孔11内具有内螺纹并形成第一螺纹部30。
在另一个实施例中，如图8-10所示，防拆连接件100一端设有外螺纹并形成第一螺纹部30，第一螺纹部30设于柱体10的一端，防拆凸块20设于柱体10远离第一螺纹部30的另一端，底座40连接于防拆凸块20背离第一螺纹部30的一侧。如此设置，防拆凸块20在防拆连接件100上的设置更加牢固。
本申请还提供一种防拆连接组件200，包括固定件210和上述防拆连接件100，防拆连接件100和固定件210两者中的一者包括具有通孔11内螺纹孔的第一螺纹部30，另一者包括设有外螺纹的第二螺纹部2102，第一螺纹部30与第二螺纹部2102螺纹配合连接。
本申请提供的防拆连接件100组件，具有防止拆卸的功能。作业人员只能通过与固定件210配合的螺母扳手以及与防拆连接件100配合的接头扳手将二者旋紧，而无法旋松。
在如图1-7所示的实施例中，防拆连接件100内开设有通孔11，通孔11具有内螺纹并形成第一螺纹部30；固定件210的端部沿轴向向外突出形成具有外螺纹的第二螺纹部2102，固定件210通过第二螺纹部2102伸入通孔11并螺纹连接于防拆连接件100。
如此设置，防拆连接件100和固定件210之间形成了更加稳固可靠的螺纹连接。
具体地，在本实施例中，防拆连接件100为防拆接头，固定件210为固定件，二者之间通过螺纹连接。在其他实施例中，防拆连接件100也可以是防拆螺母，固定件210为管接头，甚至固定件210及管接头均设置有防拆结构，即防拆连接件100及固定件210的外周壁均设有防拆凸块20。
进一步地，固定件210与防拆连接件100安装固定后，防拆连接件100的直径为防拆连接件100组件的直径的最大值。
需要说明的是，本实施方式中，防拆连接件100的直径指的是防拆连接件100各个部位直径中的最大值，例如防拆凸块20的最大外径，而不是防拆连接件100外周壁的直径；当防拆连接件100还包括底座40时，防拆连接件100的直径是指底座40的外径。
如此设置，技术人员可以使用外部工具夹持防拆连接件100的外部，实现对防拆连接件100与固定件210的强制拆卸。技术人员使用外部工具夹持防拆连接件100中直径最大的位置，可避免外部工具挤压防拆连接件100组件中的其他元件。
在如图8-10所示的实施例中，防拆凸块20位于防拆连接件100的一端，防拆连接件100的另一端设有外螺纹并形成第一螺纹部30，泄力面22朝向第一螺纹部30；固定件210设有装配孔2101，装配孔2101内设有内螺纹并形成第二螺纹部2102，第二螺纹部2102与防拆连接件100的第一螺纹部30相配合。
防拆连接组件200在装配时，防拆连接件100设有第一螺纹部30的一端伸入固定件210的装配孔2101内，并且，通过第二螺纹部2102与第一螺纹部30相配合以使固定件210与防拆连接件100螺纹连接。第二螺纹部2102和第一螺纹部30的加工工艺成熟且加工方式简单，如此，降低了防拆连接组件200的加工难度，提高了防拆连接组件200的生产效率。
在本实施例中，泄力面22朝向第一螺纹部30，且受力面21和泄力面22沿着防拆连接件100的周向设置于防拆凸块20的两侧。防拆连接件100在装配过程中，外部工具作用于防拆凸块20的受力面21上，使防拆连接件100配合外部工具沿着一个方向(该方向可以是逆时针也可以是顺时针)发生旋转，最终使防拆连接件100装配于固定件210上。当需要将防拆连接件100拆卸时，需要将防拆连接件100沿着与装配时相反的方向进行旋转。而此时，由于泄力面22的作用，使得通过外部工具对防拆连接件100进行反向松动时，泄力面22将外部工具抬升，使得外部工具无法受力，无法反向打开，由此实现了仅通过设置防拆凸块20，且在防拆凸块20设置受力面21和泄力面22即可实现防拆连接件100的防拆卸的功能。以上防拆连接件100的设计简单且易于装配，大大降低了空调设备300的使用成本。又因为泄力面22朝向第一螺纹部30，因此，进一步增大了防拆连接件100拆卸的难度。
本申请提供的防拆连接件100组件，具有防止拆卸的功能，其中防拆连接件100与固定件210间实现了不可拆卸的固定连接。作业人员只能通过螺母扳手以及接头扳手将固定件210与防拆连接件100旋紧，而无法将二者旋松；此外，防拆凸块20设置在防拆连接件100的外周壁，更方便作业人员将接头扳手快速套设在防拆连接件100的外周壁，提高了作业便利性，特别是便于套设尺寸较小的防拆连接件100；另外，防拆凸块20设置在防拆连接件100的外周壁上，增大了接头扳手对防拆连接件100的旋紧力矩的力臂或力偶臂长度，如此作业人员可以更加省力地完成固定件210与防拆连接件100的连接。
本申请还提供一种空调设备300，包括第一管体310、第二管体320以及上述的防拆 连接组件200，第一管体310及第二管体320分别与防拆连接件100及固定件210连接。如此设置，大大降低了空调设备300的装配复杂程度，提高了空调设备300的装配效率。
空调设备300在装配时，第一管体310固设于防拆连接件100，第二管体320的一端被夹紧固定于防拆连接件100和固定件210之间。因此，将第二管体320的一端装设于固定件210的装配腔内，再将防拆连接件100与固定件210装配到一起，便可实现第一管体310与第二管体320的连接。如此，大大降低了空调设备300的装配复杂程度，提高了空调设备300的装配效率。
在一实施例中，如图10所示，防拆连接件100和固定件210之间设有密封圈330，密封圈330套设于防拆连接件100靠近第二管体320的一端。如此，密封圈330能够防止第二管体320内的流体介质发生泄漏。
进一步地，空调设备300还包括空调室内机和空调室外机，第一管体310连接空调室内机，第二管体320连接空调室外机。
在其中一个实施方式中，防拆连接件100或固定件210上设置有定位段111，定位段111与第一管体310或第二管体320其中之一抵接并定位第一管体310或第二管体320。
具体地，在如图1-7所示的实施例中，防拆连接件100内部开设有通孔11，通孔11具有相互连通的第一螺纹部30与定位段111，固定件210的端部沿轴向向外突出形成具有外螺纹的第二螺纹部2102，固定件210通过第二螺纹部2102伸入通孔11并螺纹连接于防拆连接件100；第一管体310或第二管体320伸入通孔11内的最大外径大于定位段111的最小内径，第一管体310或第二管体320能够在通孔11内运动直至定位段111抵接于二者之一的外壁，因而定位段111可以限制第一管体310或第二管体320沿伸入通孔11的方向运动并离开通孔11。在如图8-10所示的实施例中，定位段111设置于固定件210上，其定位原理与上述定位原理大致相同，在此不做赘述。
如此设置，防拆连接件100和固定件210之间形成了更加稳固可靠的螺纹连接；定位段111的内壁面可以与第一管体310或第二管体320其中之一的外壁面抵接，从而限制第一管体310或第二管体320在通孔11内移动，防止其从通孔11中滑出。
进一步地，如图10所示，定位段111设有锥形定位面，第一管体310或第二管体320的端部设有扩口部，且第一管体310或第二管体320伸入通孔11内，锥形定位面与扩口部的外壁抵接。
具体地，在本实施例中，定位段111内径较小的一侧靠近防拆连接件100的端部；与之相适应地，第一管体310或第二管体320伸入通孔11内的端部设有扩口部，扩口部的外壁呈圆锥面且抵接于定位段111的内壁。当固定件210与防拆连接件100安装后，固定件210的第二螺纹部2102伸入通孔11内并压紧扩口部，因而扩口部被限制在第二螺纹部2102与定位段111的内壁面之间，进而实现了定位段111对第一管体310或第二管体320的定位。
如此设置，能够进一步保证第一管体310或第二管体320相对于防拆连接件100或固定件210之间的同轴度，第一管体310或第二管体320的定位效果更加可靠，不易发生晃动；此外，定位段111能够贴合于扩口部的外壁，使得防拆连接件100组件具有更好的密封效果，防止冷媒从通孔11内渗出泄露。
可以理解，在其他实施方式中，定位段111也可以是阶梯孔或者其他形状的孔，与之相适应地，扩口部也可以是其他形状的回转面结构，例如扩口部也可以是第一管体310或第二管体320末端沿径向突出形成的变径段，当固定件210与防拆连接件100安装后，扩口部仍可以被限制在第二螺纹部2102与定位段111的内壁面之间，从而对第一管体310或第二管体320定位。
进一步的，如图10所示，防拆连接件100端部外壁设有第一锥形面50，固定件210装配孔2101内对应设有第二锥形面2103。第二管体320一端设有锥形夹持部3201，锥形夹持部3201被夹紧固定于第一锥形面50和第二锥形面2103之间。在装配时，第二管体 320的锥形夹持部3201卡在第二锥形面2103处，再将防拆连接件100与固定件210装配到一起，便可将锥形夹持部3201夹紧固定于第一锥形面50和第二锥形面2103之间。第一锥形面50和第二锥形面2103易于加工，并且，如此设置，增大了锥形夹持部3201和防拆连接件100以及锥形夹持部3201和固定件210的接触面积，有利于提高空调设备300的装配稳定性。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
