Description

防拆卸接管装置及具有该防拆卸接管装置的空调器
技术领域
本发明属于空调管路连接技术领域，尤其涉及一种防拆卸接管装置及具有该防拆卸接管装置的空调器。　
背景技术
目前，空调器室内侧的蒸发器和室外机的管路是使用以可拆卸方式连接的管接头和接管螺母连接的。接管螺母的外表面为棱柱面，具有施力切面；管接头一般是一体式管接头，主要由螺纹段和棱柱段两部分组成。在连接接管螺母和管接头时，通过对管接头的棱柱段施加顺时针力矩，以使螺纹段与棱柱段一起旋转，从而管接头可与接管螺母紧密配合而形成密封面。在拆卸接管螺母和管接头时，通过对管接头的棱柱段施加逆时针力矩，以使螺纹段与棱柱段一起旋转而使管接头与接管螺母的配合松开。
然而由于管接头和接管螺母以可拆卸的方式连接，这会因误拆卸而导致冷媒泄漏，特别是对于使用可燃性制冷剂的空调器，冷媒的泄漏还可能会引发安全事故，因此在EN60335-2-40以及GB4706.32-2012标准中要求使用可燃性制冷剂的空调器的室内侧不允许重复使用可拆卸接头。
为了解决可拆卸管接头不符合标准的问题，现有技术中采用了蒸发器接管和室外机接管之间采用焊接的方式连接。焊接虽符合标准，但是焊接使得蒸发器和接管的连接操作复杂，同时在客户室内进行焊接作业也存在一定的风险和麻烦。　　　
发明内容
本发明的主要目的在于提供一种防拆卸接管装置及具有该防拆卸接管装置的空调器，旨在解决现有技术空调器所用的管接头与接管螺母之间存在误拆卸而造成的冷媒泄露。
为了实现发明目的，本发明提供一种防拆卸接管装置，包括第一连接管、第二连接管、与第一连接管的一端连接的第一接头以及与第二连接管的一端连接的用于与第一接头连接的第二接头。所述防拆卸接管装置还包括防拆帽，所述防拆帽具有用于容纳第一接头和第二接头的保护筒、从保护筒的一端延伸出来的滑筒、以及弹性伸入保护筒内的卡钩。所述滑筒可沿第二连接管移动的套设在第二连接管上，所述滑筒朝向第二接头的移动带动保护筒套设在第二接头和第一接头上以及使卡钩阻挡在第二接头或第一接头上来阻挡保护筒反向移动而露出第一接头。
优选地，所述保护筒上沿远离滑筒方向延伸出弹性臂，所述弹性臂末端向保护筒内弯折延伸出所述卡勾。
优选地，所述卡勾之远离滑筒的一侧形成有斜角。
优选地，所述滑筒呈锥管状，且所述滑筒之远离保护筒的一端可沿第二连接管移动的套设在第二连接管上，所述第二接头具有可套接在滑筒内的锥管段。
优选地，所述滑筒形成有可弹性收拢的若干倒扣卡爪，每一倒扣卡爪具有可抵接锥管段之远离保护筒一端的抵顶壁。
优选地，所述第一接头包括用以供旋拧工具操作的外六角段及外螺纹段，所述第二接头包括用以供旋拧工具操作的棱柱面段，所述滑筒在移向第二接头时使卡钩阻挡在第二接头的棱柱面段或第一接头的外六角段上。
优选地，所述保护筒延伸至套设在第一接头的外六角段。
优选地，所述第二接头还包括设置于所述棱柱面段内的内螺纹段，所述内螺纹段的内螺纹与所述第一接头的外螺纹段的外螺纹相锁合，所述第二接头的锥管段的内部与所述内螺纹段之间的连接处形成一第一锥面，所述第一接头的所述外螺纹段的伸入所述第二接头内的端部形成有用以与所述第一锥面配合的第二锥面。所述滑筒呈锥管状，且所述滑筒之远离保护筒的一端可沿第二连接管移动的套设在第二连接管上，所述第二接头具有可套接在滑筒内的锥管段。
为了实现发明目的，本发明还提供一种防拆卸接管装置，包括第一连接管以及与第一连接管的一端连接的第一接头，该第一接头用于与第二连接管连接的第二接头连接。所述防拆卸接管装置还包括防拆帽，所述防拆帽具有用于容纳第一接头和第二接头的保护筒、从保护筒的一端延伸出来的滑筒、以及弹性伸入保护筒内的卡钩。所述滑筒可沿第一连接管移动的套设在第一连接管上，所述滑筒朝向第二接头的移动带动保护筒套设在第一接头和第二接头上以及使卡钩阻挡在第一接头或第二接头上来阻挡保护筒反向移动而露出第二接头。
优选地，所述保护筒上沿远离滑筒方向延伸出弹性臂，所述弹性臂末端向保护筒内弯折延伸出所述卡勾。

相应地，本发明还提供一种空调器，其包括室内机及室外机。所述空调器还上述的防拆卸接管装置，所述第一连接管与所述第二连接管分别连接于所述室外机和所述室内机上。
由于本发明防拆卸接管装置及具有该防拆卸接管装置的空调器的保护筒可套设在第一接头和第二接头上，这使得旋拧工具无法直接施力于第一接头和第二接头，而且由于卡勾阻挡在第一接头或第二接头上，在旋拧工具施力于防折帽时，卡勾阻挡防折帽移动，因此无法移开防折帽后而通过旋拧工具施力于第一接头和第二接头，从而避免了第一接头和第二接头的误拆卸，进而避免了空调器的冷媒泄漏。

具体实施方式
　　　应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
　　　请参阅图1和图2，本发明一优选实施例提供的防拆卸接管装置10包括第一连接管20、第二连接管30及连接所述第一连接管20与所述第二连接管30的防拆卸管接头组件40。
　　　所述防拆卸管接头组件40包括与所述第一连接管20的一端连接的第一接头及与所述第二连接管30的一端连接的第二接头，在本实施例中，第一接头为管接头50，第二接头为接管螺母60，管接头50与接管螺母60螺纹锁合以连接第一连接管20和第二连接管30。所述管接头50包括用以供旋拧工具操作的外六角段51及外螺纹段52。所述接管螺母60包括用以供旋拧工具操作的棱柱面段61。
　　　所述防拆卸管接头组件40还包括可移动的套设在第二连接管30上的防拆帽70。所述防折帽70包括圆柱面段73、锥面段74以及若干从圆柱面段73延伸出来的在该圆柱面段73圆周方向上排列的弹性臂75。
　　　锥面段74从圆柱面段73一端延伸出来，该锥面段74远离圆柱面段73的一端可沿第二连接管30移动的套设在第二连接管30上，从而该锥面段74形成可移动的套设在第二连接管30上的滑筒，以使防拆帽70可沿第二连接管30移动。
　　　圆柱面段73与第二连接管30同轴设置，其另一端延伸至包围所述管接头50的外六角段51，因而在锥面段74沿第二连接管30移动至接管螺母60时，圆柱面段73可套设在所述接管螺母60的棱柱面段61和所述管接头50的外六角段51上，使得旋拧工具无法施力于接管螺母60和管接头50，从而该圆柱面段73形成可套设在管接头50与接管螺母60上的保护筒。
　　　每一弹性臂75沿圆柱面段73轴心线方向延伸，其末端向弯折延伸出卡勾76，所述若干弹性臂75的卡勾76滑过所述接管螺母60的棱柱面段61后勾于所述棱柱面段61的端面62上，从而卡勾76阻挡在该端面62上。
　　　由于圆柱面段73套设在所述接管螺母60的棱柱面段61和所述管接头50的外六角段51上，这使得旋拧工具无法直接施力于管接头50与接管螺母60；而且由于卡勾76阻挡在该端面62上，在旋拧工具施力于防折帽70时，卡勾76勾挡在该端面62，从而阻挡防折帽70向远离管接头50的方向移动而露出接管螺母60和管接头50，因此无法通过移开防折帽70后而通过旋拧工具施力于管接头50与接管螺母60，从而避免了管接头50与接管螺母60的误拆卸，进而避免了空调器连接管被安装人员或用户误拆卸下来而造成空调器的冷媒泄漏。
　　　进一步的，所述接管螺母60还包括连接于所述棱柱面段61的锥管段65，在卡勾76阻挡在端面62上时，锥管段65置于锥面段74内。在锥管段65为多面锥管状以及锥面段74的内壁也为多面锥管状时，锥管段65可以阻挡防拆帽70相对于接管螺母60转动。在锥管段65为圆锥管状以及锥面段74的内壁也为圆锥管状时，锥面段74可相对锥管段65沿圆周方向滑动，这使得在旋拧工具作用于防拆帽70时，防拆帽70相对于接管螺母60可以360度转动，从而在防拆帽70转动过程中，卡勾76在端面62上滑动而始终阻挡防折帽70向远离管接头50的方向移动而露出接管螺母60和管接头50，因此防拆帽70更进一步地达到防拆的功能，在本实施例中，锥管段65为圆锥管状。
　　　进一步的，所述弹性臂75的卡勾76之远离锥面段74的一侧形成斜角77，该斜角77使卡勾76在斜角77的导引下顺利地滑过棱柱面段61，然后抵于棱柱面段61的端面62上。
　　　进一步的，所述锥面段74形成有可弹性收拢的若干倒扣卡爪78，每一倒扣卡爪78具有抵顶壁79，所述若干倒扣卡爪78的抵顶壁79抵顶于所述接管螺母60的锥管段65之远离圆柱面段73的端面63。
　　　进一步的，所述接管螺母60还包括设置于所述棱柱面段61内的内螺纹段66，所述内螺纹段66的内螺纹与所述管接头50的外螺纹段52的外螺纹相锁合。所述接管螺母60的锥管段65的内部与所述内螺纹段66之间的连接处形成一第一锥面67。
　　　进一步的，所述管接头50的所述外螺纹段52的伸入所述接管螺母60内的端部形成有用以与所述第一锥面67配合的第二锥面53。所述接管螺母60的内部于所述内螺纹段66与所述第一锥面67之间开设有一环形槽68。
　　　进一步的，所述第二连接管30的伸入所述接管螺母60内的端部设置有开口渐宽的连接部31，所述连接部31夹置于所述第一锥面67与所述第二锥面53之间。
　　　在上述防拆卸接管装置10的安装过程中，将管接头50固定在第一连接管20的一端，将防拆帽70的锥面段74滑动的套设在第二连接管30上，将接管螺母60的第一锥面67固定在第二连接管30的连接部31上；接着通过旋拧工具分别旋拧管接头50的外六角段51与接管螺母60的棱柱面段61，使得管接头50的外螺纹段52锁入所述接管螺母60的内螺纹段66，并将第二连接管30的连接部31夹置于第一锥面67与第二锥面53之间；然后将朝向接管螺母60移动防拆帽70，这使锥面段74沿第一连接管20移动以及使圆柱面段73向套设接管螺母60和管接头50的方移动，在圆柱面段73移动的过程中，接管螺母60的棱柱面段61抵接卡勾76的斜角77而使弹性臂75向外弹性形变，在卡勾76滑过所述接管螺母60的棱柱面段61后，弹性臂75弹性复位而使卡勾76阻挡在接管螺母60的端面62上，此时，倒扣卡爪78弹性紧围于所述锥管段65上而完成安装，因此上述防拆卸接管装置10的结构简单、安装简单、且实现了防误拆卸的功能。
　　　上述实施例防拆卸接管装置10的卡勾76阻挡在接管螺母60的端面62上来防止移开防折帽70而通过旋拧工具施力于管接头50与接管螺母60，当然卡勾76还可设计为阻挡在管接头50的外六角段51上来防止移开防折帽70而通过旋拧工具施力于管接头50与接管螺母60。
　　　上述防拆卸接管装置10应用于一空调器（图未示）上，其中，该空调器包括室内机（图未示）、室外机（图未示）及上述防拆卸接管装置10，所述第一连接管20与所述第二连接管30分别连接于所述室外机和所述室内机上。第一连接管20和第二连接管30通过防拆卸接管装置10连接起来，而且第一连接管20与第二连接管30是不可拆卸连接，有效地防止因误拆卸而导到冷媒泄露的现象产生，空调器具有更好的安全性能。
　　　以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
