需要说明的是，当元件被称为“设于”另一个元件，它可以直接设在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“设于”另一个元件，它可以是直接设置在另一个元件上或者可能同时存在居中元件。当一个元件被认为是“固定于”另一个元件，它可以是直接固定在另一个元件上或者可能同时存在居中元件。
除非另有定义，本申请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。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。本申请所使用的术语“和/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。
如图1所示，本申请请求保护的连接接头100，用以连接配合接头200和连接管300，需要说明的是，本申请的配合接头200与连接接头100具体可根据使用的需求设置为配套的公、母接头，其中，配合接头200具体安装于盛装有液体的箱体(图未示)上，连接管300具体可设置为软管。
如图3、图4所示，本申请一实施例所提供的连接接头100，包括接头主体10、锁簧 20、固定圈30、第一密封圈40、间隔环50及第二密封圈60。
如图5至图9所示，接头主体10上开设有插槽11，锁簧20能够通过插槽11插入至接头主体10，以将配合接头200锁定至接头主体10。也就是说，本申请的连接接头100具体是用锁簧20将插入至接头主体10内的配合接头200进行锁定。需要说明的是，本申请的锁簧20插入至接头主体10上插槽11的方向，与配合接头200与连接接头100装配时插入至连接接头100的方向垂直。
在本申请中，接头主体10在插槽11的槽壁111上设有挡台12，挡台12具有第一端面121和第二端面122，第一端面121与第二端面122分居于挡台12的两侧，其中，第一端面121与接头主体10的内周壁101设于同一面上；锁簧20包括弹性条板21，并在弹性条板21上设有锁块22和抵推块23，锁簧20能够带动锁块22贴合于内周壁101并插入至插槽11，直至锁块22抵靠于挡台12的第一端面121；抵推块23上设有抵推斜面231，配合接头200能够通过抵推斜面231推顶抵推块23，且抵推块23能够利用弹性条板21的弹性形变驱使锁块22运动至挡台12上第二端面122所在的位置，以将锁簧20锁定至接头主体10上。可以理解的是，通过抵推块23上抵推斜面231的结构设置，利用配合接头200在插入接头主体的过程中实现对抵推斜面231的推挤，来实现对弹性条板21弹性形变的驱动，使得该弹性条板21在弹性形变的同时能够带动锁块22由挡台12的第一端面121运动至第二端面122。也就是说，本申请的连接接头100与配合接头200插接配合时，插入的配合接头200能够作用于锁簧20的抵推块23的抵推斜面231上，并利用弹性条板21弹性形变的结构特性，驱使锁块22由抵靠在挡台12的第一端面121运动至与挡台12的第二端面122进行抵接配合，以此实现将锁簧20在接头主体10上的锁定，进而实现对插入至该连接接头100上的配合接头200进行锁定。
在本申请中，通过上述合理的结构设置，使得该连接接头100与配合接头200插接配合时，配合接头200能够作用于弹性条板21上抵推块23，利用弹性条板21弹性形变的结构特性，驱使弹性条板21沿配合接头200的轴向插入方向进行弹性形变，使得锁块22在弹性条板21的带动下能够绕过挡台12的第一端面121并运动至第二端面122上，这样能够实现锁簧20在接头主体10上的锁定，并固定配合接头200，使得该配合接头200能够在连接接头100上一次装配到位，且在此过程中，无需借助外部工具或者再次手动装配，使得该连接接头100便于与配合接头200装配，并提高了该连接接头100与配合接头200两者装配后整体结构的稳定性；同时，锁簧20在配合接头200的带动能够继续插入至接头主体100，这样实现了锁簧20在接头主体10上安装位置的锁定，避免后续再次按压锁簧20进行锁定，这样能够提高该连接接头100与配合接头200进行装配时的装配效率。
可以理解，本申请的锁簧20上弹性条板21的数量为两个，且每个弹性条板21上分别设有锁块22及抵推块23；而，该接头主体10上挡台12与锁块22一一对应设置，以满足该锁簧20在接头主体10上装配的使用需求。
需要说明的是，配合接头200的外壁上设有凸圈210，且该配合接头200能够用凸圈210推顶抵推块23上的抵推斜面231，利用抵推斜面231的斜面结构特性，该配合接头200上凸圈210开始推顶抵推块23上抵推斜面231时，由于该弹性条板21上锁块22贴合于接头主体10的内周壁101，使得抵推块23只能驱使弹性条板21朝配合接头200的轴向插入方向进行变形，亦即带动锁块22贴合于挡台12的第一端面121进行运动；而当锁块22脱离第一端面121后，受到弹性条板21弹性形变后所产生的弹性复位力，以限制弹性条板21继续朝配合接头200的轴向插入方向进行变形，这样配合接头200上凸圈210继续推顶抵推块23上抵推斜面231时，该弹性条板21自接头主体10的内周壁101向外扩张，亦即带动锁块22运动至挡台12的第二端面122所在的位置，并使抵推块23上抵推斜面231脱离配合接头200上凸圈210的抵压；最后，因弹性条板21的弹性复位，可带动锁块沿着挡台12上第二端面122朝配合接头200轴向插入方向的相反方向运动，并实现该锁块22与挡台12之间抵接配合，亦即实现该接头主体10通过挡台12与锁块22之间的抵接配合对锁簧20的锁定。当然了，锁簧20在插入接头主体10上插槽11的过程中，锁簧20上两个弹性条板21受压合拢，以使该锁簧20在插入接头主体10的过程中，该锁簧20上锁块22始终贴合在接头主体10的内周壁101上。
本申请的挡台12上开设有导向斜面123，锁块22上开设有用以匹配导向斜面123的导向配合面221，以导向斜面123与导向配合面221之间的配合为导向，引导锁块22运动至第二端面122。这样可使弹性条板21在弹性形变复位的过程中，导向斜面123能够对锁块22的运动方向起到导向的作用，以此确保锁块22能够在弹性条板21的带动下运动至挡台12的第二端面122所在的位置，并实现该锁块22与挡台12之间的锁定。
本申请的弹性条板21上设有凸块24，凸块24具有抵接面241，抵接面241贴合于内周壁101设置，以对抵推块23驱使弹性条板21沿着配合接头200轴向插入方向的弹性形变进行导向。也就是说，本申请的锁簧20在插入接头主体10的过程中，该弹性条板21上锁块22及凸块24同时贴合于内周壁101，且当弹性条板21一开始受到抵推块23的驱动而弹性形变时，该凸块24上抵接面241还是贴合于内周壁101设置，这样可实现导向的作用，以此确保弹性条板21能够带动锁块22脱离挡台12上第一端面121并运动至挡台12的第二端面122所在的位置。
可以理解，所述弹性条板21上朝向所述配合接头200的轴向插入方向的一侧面上设 有凸块24，使得所述弹性条板21只能沿着所述配合接头200的轴向插入方向进行弹性形变。
需要说明的是，配合接头200轴向插入至接头主体10内并用锁簧20进行锁定的过程中，该凸块24上抵接面241始终贴合于接头主体10的内周壁101设置，这样以凸块24上抵接面241与接头主体10上内周壁101之间的贴合为导向，不仅能够引导弹性条板21沿着配合接头200轴向插入方向进行弹性形变，以使锁块22脱离挡台12的第一端面121，而且还能够引导弹性条板21沿着配合接头200轴向插入方向的相反方向进行弹性形变，以使锁块22运动至挡台12的第二端面122。
本申请的锁簧20还包括导向挡板25，且锁簧20能够通过导向挡板25作用于配合接头200，以将配合接头200锁定至接头主体10上，以此具体实现该锁簧20对插入至接头主体10内的配合接头200的锁定。
其中，接头主体10上开设有用以匹配导向挡板25的滑槽13，以导向挡板25与滑槽13之间的配合为导向，引导锁簧20插入至接头主体10的插槽11，这样可便于将该锁簧20预装至接头主体10上，并满足将锁簧20插装至接头主体10上的使用需求。
可以理解的是，通过上述导向挡板25的结构设置，以此具体实现该锁簧20对插入至接头主体10内的配合接头200进行锁定，且可通过导向挡板25与滑槽13之间的配合，对锁簧20插入至接头主体10的过程中起到导向的作用，以满足将锁簧20插装至接头主体10上的使用需求。
本申请的弹性条板21上还设有凸台26，且锁块22抵靠至第一端面121时，凸台26能够卡接于接头主体10，以限制锁簧20脱离接头主体10，使得该锁簧20预装至接头主体10上时，利用凸台26与接头主体10之间的卡接，能够对预装至接头主体10上的锁簧20起到防脱开的限位作用，能够防止锁簧20从接头主体10上脱开，使得该连接接头100能够整体向外供货，以便于后续的包装及运输，具有降低成本的作用。
具体地，接头主体10上设有凸台抵接面102，凸台抵接面102设置于接头主体10上内周壁101的外侧，用以匹配凸台26，这样当该锁簧20插入至接头主体10的插槽11时，该锁簧20上凸台26受到内周壁101的挤压能够带动对应的弹性条板21收缩，而当凸台26脱离内周壁101并运动至凸台抵接面102所在的位置时，弹性条板21能够弹性复位并带动凸台26向外运动，并实现凸台26与凸台抵接面102之间的卡接，这样实现了限制锁簧20防止脱离接头主体10的作用。
本申请的弹性条板21上设有多个凸刺211，多个凸刺211依次间隔地设置于弹性条板21上沿着锁簧20插入接头主体10内方向的一侧端面上，这样能够利用凸刺211与手指接 触时对手指产生的刺痛效果，能够起到约束工人的作用，以此确保该连接接头100与配合接头200两者装配后的结构稳定性。
另外，本申请的锁簧20上还设有限位挡板27，且当锁块22抵靠至第二端面122时，限位挡板27能够抵接接头主体10，以限制锁簧20继续插入至接头主体10内，这样在满足该锁簧20在接头主体10上装配的基础上，使得后续人们在解锁连接接头100与配合接头200时，可用解锁工具起翘限位挡板27的方式，来实现对锁簧20在接头主体10上的解锁。
其中，本申请的限位挡板27上朝远离接头主体10的方向部分凸起并形成有起翘部271，以供解锁工具插入至该起翘部271所在的位置，并实现对限位挡板27的起翘，这样便于对该连接接头100与配合接头200在完全装配到位后的解锁。需要说明的是，上述解锁工具可设置为具有扁平头的结构，且该扁平头能够插入至该起翘部271内。
可以理解的是，通过上述限位挡板27的结构设置，以此具体实现该配合接头200在接头主体10内装配到位后，该锁簧20整体能够在接头主体10上的锁定。
请一并参见图12-图17，配合接头200轴向插入至接头主体10内的过程可以详述为第一阶段至第四阶段如下：
请参阅图12A-图12D，在第一阶段，锁簧20能够带动锁块22贴合于内周壁101并插入至插槽11，直至锁块22抵靠于挡台12的第一端面121。配合接头200插入至连接接头100的接头主体10，并抵接于锁簧20的弹性条板21上的抵推块23。
请参阅图13A-图13D，在第二阶段，配合接头200通过凸圈210推顶锁簧20的弹性条板21上的抵推块23，驱使弹性条板21沿配合接头200的轴向插入方向进行弹性形变。由于弹性条板21上锁块22贴合于接头主体10的内周壁101，使得抵推块23只能驱使弹性条板21朝配合接头200的轴向插入方向进行变形，而第一端面121与接头主体10的内周壁101设于同一面上，亦即驱使锁块22贴合于挡台12的第一端面121进行运动。弹性条板21只能沿着配合接头200轴向发生弹性形变，并且限制弹性条板21往配合接头200径向发生变形。
请参阅图14A-图14D以及图15A-图15D，在第三阶段，当锁块22贴合于挡台12的第一端面121进行运动至脱离第一端面121后，受到弹性条板21弹性形变后所产生的弹性复位力，以限制弹性条板21继续朝配合接头200的轴向插入方向进行变形。此外，由于配合接头对抵推块上抵推斜面的作用力可根据力的分解为对弹性条板21两个分力，其中一个分力为沿着配合接头200插入方向，另一个分力为沿着锁簧20插入接头主体10方向。随着配合接头200上凸圈210继续推顶抵推块23，抵推块23通过抵推斜面231受到 径向的扩张作用力，该弹性条板21自接头主体10的内周壁101向外扩张，此时抵推斜面231脱离配合接头200上凸圈210的抵压，弹性条板21带动锁块22运动至挡台12的第二端面122所在的位置。
请参阅图16A-图16D，在第四阶段，因弹性条板21的弹性复位，可带动锁块沿着挡台12上第二端面122朝配合接头200轴向插入方向的相反方向运动至挡台12的第二端面122，实现该锁块22与挡台12之间抵接配合，如此实现锁簧20的自锁。
如图10、图11所示，本申请的固定圈30上设有连接筋条31，锁簧20能够通过弹性条板21带动锁块22抵靠于连接筋条31，以限制锁簧20继续插入接头主体10，这样能够对预装至接头主体10上的锁簧20起到防止过度插入的限位作用，亦即实现对锁簧20与接头主体10之间装配位置的确定，以满足后续对该连接接头100整体包装及运输的使用需求。需要说明的是，本申请的固定圈30上设有避空结构(图未示)，用以对锁簧20插入至接头主体10起到避让的作用，以满足锁簧20能够插入至接头主体10内的使用需求。
其中，本申请的固定圈30上设有防呆件32，接头主体10上设有用以匹配防呆件32的防呆配合件14，以防呆件32与防呆配合件14之间的配合为导向，引导固定圈30安装至接头主体10内，这样可对固定圈30在接头主体10上的装配起到防呆的作用，以便于将该固定圈30安装至接头主体10内。需要说明的是，上述固定圈30在接头主体10上的装配起到防呆的作用，具体指固定圈30在接头主体10上的装配位置进行精确定位。
具体地，本申请的防呆件32具体设置为固定圈30外周壁301上开设有的条槽321，防呆配合件14设置为接头主体10上内周壁101上设有的凸筋141，且条槽321与凸筋141之间凹凸配合，能够对固定圈30在接头主体10上的装配起到导向的作用。当然了，防呆件32及防呆配合件14不局限为图示所示的条槽321和凸筋141，对本领域技术人员来说，可将防呆件32及防呆配合件14均设置为一一对应的画线结构，在此就不展开阐述。
本申请的固定圈30的外周壁301上设有凸扣33，接头主体10上开设有用以匹配凸扣33的扣槽15，固定圈30能够通过凸扣33与扣槽15之间的配合卡接于接头主体10，以此具体实现该固定圈30与接头主体10之间的装配连接，以便于将固定圈30安装至接头主体10上。
本申请的第一密封圈40、间隔环50及第二密封圈60依次嵌装于接头主体10内，且配合接头200能够与接头主体10配合，并同时挤压第一密封圈40及第二密封圈60发生形变，使得该连接接头100与配合接头200插接配合时，能够起到双重密封的作用，以满足连接接头100与配合接头200之间装配密封的使用需求。
如图2所示，间隔环50上设置有限位台阶51，接头主体10上设有用以匹配限位台阶 51的台阶面16，间隔环50能够安装至接头主体10内，直至该间隔环50上限位台阶51抵靠在台阶面16上，亦即实现对间隔环50在接头主体10上装配位置的确定，这样可使该接头主体10上用以装配第一密封圈40及第二密封圈60的区域尺寸大于对应的第一密封圈40及第二密封圈60，以为对应的第一密封圈40及对应的第二密封圈60提供相应的形变空间。需要说明的是，本申请的接头主体10的内周壁101上还形成有第一限位凸台17及第二限位凸台18，第一限位凸台17能够抵接第一密封圈40，以将第一密封圈40限位至第一限位凸台17与间隔环50之间的位置，第二限位凸台18能够抵接固定圈30，以将第二密封圈60限位至间隔环50与固定圈30之间的位置，这样能够满足第一密封圈40及第二密封圈60受压形变的使用需求。
另外，需要说明的是，本申请的接头主体10上远离固定圈30的一端套接有第三密封圈70，且该连接接头100能够通过所述第三密封圈70与连接管300进行装配密封。当然了，第三密封圈70的数量也可根据使用的需求设置为多个，在此就不展开阐述。
综上，本申请的连接接头连接接头100通过上述合理的结构设置，使得该连接接头100能够与配合接头200之间一次装配到位，在此过程中，无需借助外部工具或者再次手动装配，使得该连接接头100便于与配合接头200装配，并提高了该连接接头100与配合接头200两者装配后整体结构的稳定性。
以上实施方式的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式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。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本申请，而并非用作为对本申请的限定，只要在本申请的实质精神范围内，对以上实施方式所作的适当改变和变化都落在本申请要求保护的范围内。
