具体实施方式
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
实施例1
如图1-9所示，一种防拆卸连接头，包括连接头本体4和辅助工装2。
如图4所示，连接头本体4设有螺纹孔41和开槽42；具体的，连接头本体4呈圆柱形，连接头本体4的一端设有逐渐变窄的喇叭口，由此通过喇叭口与连接管5相通；其中，螺纹孔41沿着连接头的轴线贯穿设置，由此，螺纹孔41能够与管接头3螺纹配合实现组装；开槽42沿着连接头本体4的轴线方向设置，由此，开槽42便于与辅助工装2进行配合实现组装。
本实施例中，连接头本体4的外缘与扳手等拧动工具不匹配，因此，无法使用扳手等拧动工具实现连接头本体4的转动，需要配合辅助工装2进行使用。
如图7、8所示，辅助工装2设有卡合腔21，卡合腔21设有缺口212和卡块211；具体的，缺口212的设置促使卡合腔21与外界相通，构成一个半包围的构造，此时，卡合腔21内壁的横截面呈C字型；卡块211设置在卡合腔21的内壁，其与开槽42相互配合，实现连接头本体4和辅助工装2的组装。
本实施例中，在辅助工装2的卡合腔21通过缺口212拆卸式套合在连接头本体4上时，辅助工装2的卡块211位于连接头本体4的开槽42中，由此，实现辅助工装2和连接头本体4的组装，同时，辅助工装2的外缘能够与扳手等拧紧工具配合，由此，通过扳手等拧紧工具能够带动辅助工装2旋转。
本实施例中，如图6所示，开槽42包括拧紧面和拆卸面，具体的，拧紧面为半圆等稳定形状，拧紧时能够有效传递力矩；拆卸面为带弧度的坡面形状，拧松时力矩传递效率受坡面影响大大降低；向辅助工装2上施加拧紧力矩时，辅助工装2通过拧紧面向连接头本体4施加力矩，辅助工装2带动连接头本体4旋转；向辅助工装2上施加拧松力矩时，辅助工装2通过拆卸面降低力矩传递效率，同时，辅助工装2变形失效或者促使作用在辅助工装2上的拧紧工具打滑。
本实施例使用时，如图9箭头所示方式，逆时针旋扭辅助工装2为连接头本体4的拧紧方向；顺时针旋扭辅助工装2为连接头本体4的拧松方向，具体过程如下：
首先将辅助工装2套合在连接头本体4上，此时，辅助工装2的卡块211位于连接头本体4的开槽42中；随后用扳手等拧紧工具卡合辅助工装2的外缘，逆时针进行旋转时，辅助工装2带动连接头本体4一起运动，实现连接 头本体4的拧紧；顺时针进行旋转时，辅助工装2变形失效或者促使扳手等拧紧工具打滑，辅助工装2不能带动连接头本体4一起运动，实现连接头本体4的防拆卸功能。
实施例2
本实施例与上述实施例相比，其不同之处在于，本实施例中辅助工装2包括第一端面22、第二端面23、第三端面24、第四端面25和第五端面26；其中，第一端面22、第二端面23、第三端面24、第四端面25和第五端面26依次连接构成卡合腔21，具体的，五者之间的角度为120度，由此，便于与扳手等拧紧工具进行配合；第一端面22和第五端面26之间断开构成缺口212，由此，在缺口212的作用下，实现辅助工装2和连接头本体4的组装和拆卸。
本实施例中，第一端面22和所述第四端面25构成第一防拆结构；在辅助工装2通过拆卸面降低力矩传递效率时，第一防拆结构促使辅助工装2变形，具体的，扳手等拧紧工具卡入第一拆卸结构的第一端面22和第四端面25时，在顺时针拧动时，辅助工装2的受力点在第一卡边27和第三卡边29，此时由于力臂较长，在将连接头拧松前，辅助工装2就已经变形失效了，实现连接头本体4的防拆卸。
本实施例中，第二端面23和第五端面26构成第二防拆结构，其中，第五端面26设有斜坡；在辅助工装2通过拆卸面降低力矩传递效率时，第二防拆结构促使扳手等拧紧工具打滑，具体的，扳手等拧紧工具卡入第二拆卸结构的第二端面23和第五端面26时，在顺时针拧动时，辅助工装2的受力点在第二卡边28和第四卡边262，此时由于第五端面26斜坡的设计，扳手等拧紧工具无法在第四卡边262用力，会导致扳手等拧紧工具在第四卡边262打滑，实现连接头本体4的防拆卸。
实施例3
本实施例与上述实施例相比，其不同之处在于，本实施例中卡合腔21设有围边213；在卡合腔21套合连接头本体4时，围边213抵接连接头本体4；具体的，卡合腔21的一端设有围边213，围边213与卡块211相互垂直，由此，在围边213的作用下，能够定位辅助工装2在连接头本体4上的位置，防止辅助工装2沿着连接头本体4的外缘下滑。
实施例4
本实施例与上述实施例相比，其不同之处在于，本实施例中连接头本体4设有环形槽43，环形槽43与开槽42相交，具体的，环形槽43位于连接头本体4的喇叭口上方，环形槽43到卡合腔21围边213的长度等于卡块211的长度，由此，实现辅助工装2的稳定安装；环形槽43中设有卡簧431，由此，在卡簧431位于环形槽43时，能够防止辅助工装2从喇叭口处进入连接头本体4，导致上述防拆卸功能被反置。
实施例5
本实施例与上述实施例相比，其不同之处在于，如图5所示，开槽42的一端与连接头本体4形成限位台阶421，具体的，开槽42靠近连接头本体4的喇叭口一端形成限位台阶421，由此，在限位台阶421的作用下，能够防止辅助工装2从喇叭口处进入连接头本体4，导致上述防拆卸功能被反置。
实施例6
一种连接头组件，包括管接头3和上述防拆卸连接头的构造。
本实施例中，管接头3设有贯穿的通孔，管接头3上设有外螺纹，其中，管接头3的外螺纹与连接头本体4的螺纹槽配合；管接头3与连接头本体4装配时，连接头本体4不能直接通过扳手等拧紧工具进行旋拧，其需要配合辅助工装2进行使用，在管接头3与连接头本体4接触时，将辅助工装2的卡合腔21通过缺口212套合在连接头本体4上；向辅助工装2上施加拧紧力矩时，辅助工装2通过拧紧面向连接头本体4施加力矩，辅助工装2带动连接头本体4旋转，从而实现管接头3和连接头本体4的连接；向辅助工装2上施加拧松力矩时，辅助工装2通过拆卸面降低力矩传递效率，同时，辅助工装2变形失效或者促使作用在辅助工装2上的拧紧工具打滑，从而实现管接头3和连接头本体4的防拆卸。
实施例7
如图1、2、3所示，一种空调器，空调器的蒸发器管1和连接管5采用上述连接头组件进行连接。
本实施例中，蒸发器管1连通管接头3；连接管5连通连接头本体4；将蒸发器管1和连接管5连通时，首先将管接头3与连接头本体4的螺纹孔41抵接，将辅助工装2的卡合腔21通过缺口212套合在连接头本体4上；向辅 助工装2上施加拧紧力矩时，辅助工装2通过拧紧面向连接头本体4施加力矩，辅助工装2带动连接头本体4旋转，从而实现管接头3和连接头本体4的连接；向辅助工装2上施加拧松力矩时，辅助工装2通过拆卸面降低力矩传递效率，同时，辅助工装2变形失效或者促使作用在辅助工装2上的拧紧工具打滑，从而实现管接头3和连接头本体4的防拆卸。
以上所述仅为本公开的一些实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
