Description
本发明涉及一种发泡枪，特别是涉及发泡枪上用于实现发泡罐安装的适配器。
在建筑装璜上经常需要使用到发泡剂，发泡剂主要是用于对板材或其它结构之间的缝隙进行涂敷，聚积在缝隙内的发泡剂膨化并固化后会封堵在缝隙处，而实现缝隙的密封。发泡剂在进行涂敷时，一般是借助于发泡枪来实现的。发泡枪的结构主要包括枪体和枪管，枪管内设有针杆，枪体内具有通液腔，适配器用于和发泡罐相连接，适配器内具有通向通液腔内的通道；枪体上设有扳机，扳机与针杆相联接，扳动扳机时，针杆会跟随扳机一起动作，针杆在扳机的带动下向着枪体的后侧方向运动后，针杆的前端与枪管前端部所设枪嘴之间会形成间隙，发泡剂会从此间隙处流出到枪管的外侧，该间隙的大小与发泡剂的流量有关。
中国专利文献(公开号CN201711246U)公开了一种发泡枪适配器,包括适配器本体、密封球及锥形弹簧,适配器本体具有内腔,内腔内旋入铜嵌件,铜嵌件内设有衬套,铜嵌件上部端面与内腔顶部端面相抵靠,铜嵌件具有进液孔和流道,密封球置于铜嵌件内,密封球与铜嵌件的内端面之间设有密封垫圈,锥形弹簧的一端顶压密封球下端,另一端顶压在固定于铜嵌件的压套上,压套内中空形成流道,上端具有跨设其上的突起锥面筋,锥面筋之间为扇形开口,压套流道通过扇形开口与铜嵌件的流道相通,锥面筋的锥度与预紧弹簧的锥顶位于同一直线。本实用新型限制了锥形弹簧的最大压缩量,避免锥形弹簧并紧堵塞,且以注塑件组合结构代替金属件,减少加工工序和零部件报废率,缩短了产品生产周期。
这种适配器内设置有单向式的密封球，为了保证密封球的单向密封效果，需要在密封球的内侧设置有锥形弹簧，通过锥形弹簧对密封球的推压，而使得密封球抵靠在所述的密封垫圈上，而实现单向密封。经常使用的发泡枪通常不会存在固化堵塞的问题，但在实际的应用过程中，由于种种原因，发泡枪停用的时间会较长，浸渍在发泡剂中的锥形弹簧处会产生固体 结晶，固体结晶较多后，则会使锥形弹簧失去活性，从而会影响到对密封球与密封垫圈之间的密封。在卸去发泡罐时，由于密封球不能及时抵触到密封垫圈上，而使得枪管内的发泡剂会自密封球与密封垫圈之间的间隙处返流到适配器的外侧，需要及时对这些反流液进行清洗，从而在使用上会带来麻烦。

进一步地，安装架上，所述的联接结构设置在安装架的上部位置处，在安装架的下部位置处具有圆筒形的套接部，所述的致动结构设置在套接部内。通过设置有套接部，而方便通过安装架来实现阀嘴的轴向运动，结构紧凑性好，便于安装。
进一步地，所述的联接结构为正向设置的正向内螺纹。所谓的正向设置，是指该螺纹的螺旋方向为通常最为常见的设置方向，反向设置的螺纹与正向设置的螺纹两者的螺旋方向相反。
进一步地，所述的致动结构包括在阀嘴和套接部之间反向设置的螺纹结构。反向设置的螺纹与正向设置的螺纹之间的螺旋方向相反，在转动安装架时，会使阀嘴在需要的轴向方向上运动。特别是在卸下发泡罐时，由于发泡罐会作适应于螺纹正向设置的方向转动，在实现发泡罐相对于安装架周向转动前，封堵结构已关闭，即使发泡罐上的喷嘴与承接孔相脱开，枪管内的发泡剂也不会返流。在装配发泡罐时，可以使安装架处于固定位置处，使封堵结构处于关闭状态，装配到位后，通过发泡罐带动安装架继续沿装配方向转动，在封堵结构打开后也使阀嘴顶开发泡罐上的喷嘴，从而能够实现发泡罐内的发泡剂顺利进入到液流通道内。
进一步地，所述的致动结构包括在阀嘴和阀芯之间反向设置的螺纹结构，所述套接部与阀嘴之间周向固定套接。通过在阀嘴和阀芯之间反向设置相联接的螺纹结构，结构简单，便于实现阀嘴相对于阀芯的轴向运动。套接部与阀嘴之间采用非圆配合，即棱柱体和棱柱孔之间的配合，或其它的异形结构的配合，而实现安装架与阀嘴之间的周向传动。
进一步地，所述安装架为回转体结构，还包括中间部和安装部，中间部的外径大于套接部的外径，安装部的外径大于中间部的外径，在轴向上，中间部位于安装部和套接部之间，所述的正向内螺纹设置在安装部的内周面上。这使得安装架整体的外周面为阶梯形结构，从而便于手的握持，在把发泡罐安装到安装架上时，安装方便快捷。
进一步地，在封堵结构处于封堵液流通道的状态下装配发泡罐，发泡罐安装到位后，转动安装架，使阀嘴顶开发泡罐上的喷嘴与封堵结构打开同步进行；在拆下发泡罐时，所述的封堵结构处于封堵液流通道的状态下。在进行发泡罐的装配时，安装架可以通过活动式的限位结构的设置，或者 是手的扶持，而使得安装架保持周向固定。使封堵结构打开与发泡罐上喷嘴的顶开同步进行，从而很好地保证发泡剂能够及时顺畅地进入到枪体内的通液腔中。但在拆下发泡罐时，所述的封堵结构处于关闭的状态上，枪管内的发泡剂不会返流到安装架位置处。
进一步地，阀芯内沿其轴向设有贯透的透孔，透孔构成了所述液流通道的一部分，在阀芯插接在阀嘴内部的一端部上一体成型有堵塞块，在阀芯内于液流通道的位置处设置有止口，堵塞块和止口构成了所述的封堵结构。这种封堵结构简单，便于设置，能够很好地适应于阀嘴的轴向运动。
进一步地，所述的透孔位于阀芯的轴线位置处，堵塞块位于透孔位置处，在堵塞块根部的两侧分别设有与透孔相通的透口。这使得便于实现堵塞块与止口之间的稳定配合，结构简单。
进一步地，在套接部外端的内周面上一体成型有内向凸环，在阀芯中部位置的外周面上一体型有外向压环，外向压环压接在内向凸环的外侧。通过所述的外向压环和内向凸环之间的压接配合，从而能够很好地实现对安装架的轴向限位，安装架在枪体上的稳定性好。
本发明具有如下有益效果：
1、通过在液流通道内设置有封堵结构，并且封堵结构的打开与关闭是由阀嘴的轴向运动所导致的，而阀嘴的轴向运动是由安装架所启动，这使得对封堵结构的操作显得方便快捷，能够很好地利用发泡枪上的现有结构，使得本安装适配器的结构简单，便于设置，且能够实现轻便省力地操作。
2、封堵结构的关闭与打开是由阀嘴的轴向运动所引起的，而阀嘴的轴向运动是由人为通过安装架进行控制的，封堵结构不会因为长时间不使用而出现失效现象，使得在更换发泡罐或卸下发泡罐时，枪管内的发泡剂不易返流到适配器的外侧，能够很好地满足发泡枪的实际使用需求。
3、所述封堵结构的设置与启动机理，从而能够实现发泡罐上喷嘴被顶开与封堵结构打开能够保持同步，在装配发泡罐时，也不易出现发泡剂的泄漏，使得发泡枪在使用过程能够保持清洁。

结合说明书附图，本安装适配器应用在发泡枪上，用于实现存储有发泡剂的发泡罐的安装。见图1，所述发泡枪的结构包括枪体2，在枪体2内设有通液腔，在枪体2的前侧联接有枪管1，枪管1与通液腔内部相通，枪体2的后侧设置有握把6，针杆4的内端伸入到枪管1内，针杆4的外端与枪体2上的流量调节机构5相联接。
本安装适配器的结构包括安装架3，安装架3周向转动、轴向限位地联接在枪体2上。在安装架3的上端侧正向设置有正向内螺纹，而在发泡罐的外端部上设有联接头，联接头上正向设置有正向外螺纹，该正向内、外螺纹联接在一起，而实现把发泡罐联接固定到安装架3上。在枪体2上螺纹联接有阀芯8，枪体2上与阀芯8螺纹联接的螺纹孔与枪体2内的通液腔相通，阀芯8本身为中空结构。在阀芯8上套接有中空的阀嘴7，阀嘴7与阀芯8之间通过至少两道密封圈9而实现液密封。阀嘴7的上端部内设置有承接口71，承接口71内形成有底环。发泡罐螺纹联接到安装架3上后，发泡罐上的喷嘴插接在承接口71内，所述的底环供喷嘴的外端部支撑，在底环顶压喷嘴后，会使喷嘴打开，发泡剂会自喷嘴内以液态形式而流出。
所述的阀嘴7在安装架3内活动设置，也即是阀嘴7在安装架3内可进行轴向运动，安装架3与阀芯8之间设置有致动结构，阀嘴7的轴向运动是由安装架3通过致动结构的传动而导致。通常情况下，该致动结构的 主体为反向设置的相互联接配合的螺纹结构，通过安装架3的转动，而实现该螺纹结构的相对周向转动，从而实现阀嘴7的轴向运动。
阀芯8、阀嘴7和安装架3三者同轴设置，在中空的阀芯8和阀嘴7内部形成有液流通道，液流通道沟通承接口71和通液腔，液流通道供发泡剂自承接口71处进入到枪体2中的通液腔内。在液流通道内设置有封堵结构，封堵结构设置在阀嘴7与阀芯8之间。阀嘴7轴向运动的结果，会导致封堵结构关闭而对液流通道实现封堵，或者使封堵结构打开而实现液流通道的导通。
安装架3为回转体结构，包括连为一体的套接部33、中间部32和安装部31，它们三者均为中空的圆筒形，从而使得在安装架3内形成有安装腔，以便于把阀芯8和阀嘴7装配在该安装腔内。图中显示，中间部32的外径大于套接部33的外径，安装部31的外径大于中间部32的外径；在轴向上，中间部32位于安装部31和套接部33之间，所述的正向内螺纹设置在安装部31的内周面上，所述的致动结构设置在套接部33内。
作为一种实施方式，所述的致动结构包括在阀嘴7和安装架3的套接部33之间反向设置的螺纹结构，其中，在套接部33的内周面上反向设置有反向内螺纹，在阀嘴7的外周面上设有与该反向内螺纹相适配联接的外螺纹。通过转动安装架3，而实现阀嘴7在阀芯8上转动，进而使得阀嘴7在阀芯8上轴向运动。
作为另一种实施方式，所述的致动结构包括在阀嘴7和阀芯8之间反向设置的螺纹结构，在阀嘴7的内周面上反向设置有反向内螺纹，在阀芯8的外周面上设有与该反向内螺纹相适配联接的外螺纹。所述套接部33与阀嘴7之间通常为棱柱体和棱柱孔之间的间隙套接配合，从而可实现套接部33带动阀嘴7在阀芯8上的相对周向转动，进而实现阀嘴7在阀芯8上的轴向运动。
前述的反向设置和正向设置是相对而言的，是以安装架3上安装部31上所设置的内螺纹的螺旋方向为基准而言的，正向设置和反向设置的螺纹螺旋方向相反。所述的正向设置，是指通常普通的内螺纹设置方向，在顺时针方向旋转发泡罐时，发泡罐上的联接头会与安装部31相联接固定；逆时针方向旋转发泡罐时，会把发泡罐自发泡枪上卸下。
阀芯8内沿其轴向设有透孔84，透孔84在阀芯8的轴向上贯透阀芯8，透孔84构成了所述液流通道的一部分。在阀芯8插接在阀嘴7内部的一端部上，也即是阀芯8的上端部上一体成型有堵塞块83，堵塞块83突出到阀芯8的上端的外侧。而在阀芯8内通过内向的突出结构而形成有止口72，所述的液流通道穿过止口72的内部，堵塞块83与止口72相适配，堵塞块83和止口72构成了所述的封堵结构，通过堵塞块83与止口72之间相抵触，即可实现液流通道的切断；堵塞块83与止口72相脱开，即可实现液流通道的导通。
所述的透孔84位于阀芯8的轴线位置处，堵塞块83位于透孔84的外侧且正对着透孔84。在堵塞块83根部的两侧分别设有与透孔84相通的透口82，阀芯8为铸造件，阀芯8的毛坯为一端封闭另一端开口，该封闭端一般为球冠形，在封闭端的相对两侧分别切口，从而会在堵塞块83的根部形成与透孔84内部相通的透口82，实现透孔84贯透阀芯8。所述的止口72可以为凹球面结构，止口72可以与球冠形的堵塞块83贴合而实现液密封。
在套接部33外端的内周面上一体成型有内向凸环34，在阀芯8中部位置的外周面上一体型有外向压环81。先把阀芯8插接到安装架3内，阀芯8在枪体2上联接到位后，外向压环81处于枪体2的外侧并与枪体2之间具有一定的间隔，而所述的内向凸环34处于该间隔内，外向压环81压接在内向凸环34的外侧，从而实现对安装架3的轴向限位，且安装架3可在阀芯8上周向转动。为了对阀嘴7向上的运动进行限位，在安装架3的中间部32的内周面上设有卡簧10，卡簧10靠近安装部31设置，在阀嘴7的外周面上一体成型有突出的突环，通过卡簧10对突环的阻挡，而限定阀嘴7向上运动的幅度，以免阀嘴7顶坏发泡罐上的喷嘴。
基于本安装适配器前述的结构，在进行发泡罐的安装时，通常使安装架3保持稳定，以免在安装架3的带动下，封闭结构处于打开状态。要实现安装架3在枪体2上的位置稳定，可以用手握持住阶梯状的安装架3，然后把发泡罐螺纹联接到安装架3的安装部31上。也可以是在枪体2上设置有偏心结构，在安装架3的相应位置处设置有缺口，通过扳动操作而使偏心结构卡接到缺口内，在发泡罐安装完毕后，再解除偏心结构的卡滞。在 进行发泡罐的安装时，封堵结构处于封闭状态。发泡罐安装到位后，继续沿装配方向转动发泡罐，安装架3会在阀芯8上转动，而使得阀嘴7顶开发泡罐上的喷嘴与封堵结构打开同步进行。在需要卸下发泡罐时，沿拆开方向转动发泡罐，发泡罐带动安装架3反向转动，反向转动的安装架3使得前述的堵塞块83与止口72抵触在一起，而实现了封堵结构的关闭。也正是由于封堵结构处于关闭状态，安装架3不能继续反向转动，从而使得发泡罐与安装架3之间实现相对反向转动，完成发泡罐的拆卸。因此，在进行发泡罐的拆卸，发泡罐被拆下前，所述的封堵结构处于关闭状态上，从而在发泡罐上的喷嘴与所述的底环相脱开前，封堵结构处于关闭的状态上，以免拆下发泡罐后，枪管1内的发泡剂会返流。
