Description

管接头的改进
本发明涉及管接头。
我的“快装”管接头(英国专利NO.1520742和其它)具有接头体，接头体带有开在一端的通孔和在开口端的锥形凸轮表面，来接收一用于在接头中锁定管的夹套。通过接头件中管和夹套的轻微拉动，夹套压向管并在接头体中锁定管。夹套可以受压进入主体来释放管。
我的“超密封”设计(英国专利NO.2167147)具有旋入接头体开口端的分离的套筒，锥形凸轮在其中形成。通过旋转套筒到接头体内增加了夹套在管上的夹紧力。夹套也锁住在接头体内且不能受压来释放管。
本发明的一个目的在于提供一种管接头，它能方便地人工地在第一状态到第二状态之间调整，第一状态中，管能在接头体中锁定和从接头体中释放，第二状态中，锁定的管不能松开。
本发明提供了一种管接头，包括具有开在一端用于接收管的一端部的通孔的接头体和具有一内凸轮表面，向开口端锥形倾斜，一夹套位于其中通过与锥形凸轮表面接合用于把管锁定在接头体中，并具有止挡装置来限制夹套进入通孔，接头体具有主体，它的通孔接收管的端部并包括该用于限制夹套***的止挡装置和与包含通到该通孔的开口端和锥形凸轮表面的主体螺纹接合的端帽，及分别在端帽和主体上的分度装置，该端帽和该主体在旋转调整的不同位置相互接合，以便通过该不同位置对旋转提供阻力，在第一位置，可***管到接头体中和通过压入夹套到接头体中而从接头体中释放管，而在第二位置夹套与止挡装置接合来防止把夹套压入接头体中从而释放管。
较好的，端帽具有环绕的内螺纹套筒部分并与主体上的外螺纹螺旋接合。
在后一种情况下，所述分度装置位于套筒口和主体的远离螺纹部的一部分之间。
更特别的，分度装置包括一在套筒口上的径向向内的凸起和设置在主体上远离螺纹的许多凸轮装置，以便相对于套筒限定帽的旋转调整的第一和第二位置。
在本发明的一个特定实施例中，主体上的第一凸轮装置具有倾斜的凸轮面，通过与套筒上的凸起结合，以便当凸起作用于凸轮把主体件旋在一起时，提供抵抗相对旋转的阻力，并在远离倾斜面处有一径向面，凸起与之接合来阻止帽从主体上松开。
而且第二凸轮装置位于主体上与第一凸轮装置相邻，以便提供接收套筒上凸起的槽来限定主体件调整旋转的一个位置。
较佳地，第二凸轮装置具有与第一凸轮装置相对的一倾斜面，当向着帽或主体的第二位置进一步把帽旋转到主体上时，用于提升套筒上的凸起越过第二凸轮装置。
此外，第三凸轮装置位于主体上，在与第一装置相邻的一边具有一倾斜面，以便为凸起提供一个阻力来限定主体件的相对旋转的第二位置。
下面是参照附图本发明一些具体实施例的描述，其中：
图1是本发明的包括***接头中的管的管接头的横截面图；
图2是沿II-II线的图1接头的截面图；
图3是图1接头的接头体的两个零件的透视图；且
图4和5是与图3和1相同的视图，表示在第二锁定状态的接头；
图6到10是与图1类似的视图来表示第一变化的实施例装置；
图11表示第二变化的实施例装置；
图12和13，14和15表示另外的变化的实施例。
首先参见附图1，表示了一个通常由序号10代表的一个管接头体，其在一端部12处具有一通孔11来接收管13的端孔部分。接头体包括主体10a和如下所述旋到主体上的帽10b。
在一离开开口端的位置，主体的通孔在台阶14处直径上有一个增加来提供第一个扩大的孔15，以便管13的一端与管接合台阶14的一端密封滑配。在台阶16处的通孔直径上有另外一个增加来形成一个扩大的孔17，靠着台阶在其中设置一“O”型密封环18，并由一间隔垫圈或压缩环19紧跟。
接头的主体10a有一从主体部的一端延伸的外螺纹部20，跟着是由21表示的凸轮部，再下来是环形径向凸缘22。接头体的帽10b环绕着主体并有一与主体的螺纹20啮合的内螺纹部23。帽的开口端有一如下所述与主体上的凸轮部21相配合的凸轮部24。
一由25表示的夹套安装在接头体的开口端，包括一环形件26和从环形件延伸出来到接头体通孔内并终止于头部28的弹性臂27。夹套的头部接合在向着接头体的端部收敛的锥形凸轮表面29内，通过头部与凸轮表面的接合抵靠着管13被施压从而在接头体中锁定管。
在图1所示的位置，帽10a部分旋在主体10b上并且在接头主体中的夹套的头部28和间隔垫圈19之间有间隙，允许夹套压入接头体以便释放管。
现在参见附图2，在螺纹20和凸缘22之间的主体的凸轮部21由位置紧挨在一起，中间有一缝隙32的第一和第二凸轮30和31形成。而且，第三凸轮33位于围绕主体与第一和第二凸轮成90度处。两凸轮与帽的扩大端内侧上的凸起24接合，相对于主体形成了帽的两个不同的旋转位置。
凸轮30具有一小的倾斜40，因此，当帽拧到主体上时，凸起34可通过它接合。在凸轮的另一边有一径向面41形成了一个与凸起34接合的止挡来阻止帽的反向运动。如果用力拧帽并损坏了凸起34，安装无法使用是明显的。
凸轮30的表面41间隔相对的是具有与表面41相邻的倾斜表面42的第二凸轮31，当从所说的第一位置再旋转帽时，凸起34能够越过它。
凸轮33在它的每一边上具有成角度的斜面43和44。当帽从第一位置旋转1/4圈时，凸起34与第一斜面43接合，该斜面提供凸起越过凸轮进一步运动的阻力。当凸起正好骑在凸轮的最高点上时，帽的一端如图4所示与凸缘接合。在这一位置上把夹套拉入了接头主体的口中来除掉夹套臂和间隔垫圈之间的间隙并抵靠着管13紧紧地夹紧夹套的臂。在这个位置从图4中清晰可见夹套不能压入接头体来释放管。
当要求从接头体中释放管时，帽反转1/4圈直到帽上的凸起接合在主体的第一和第二凸轮之间，然后把夹套压入接头体来释放管。
从下面的说明和从“超密封”位置装配帽到主体上来释放帽的过程，能更好的理解凸轮的功能。
装配操作者装配帽到主体上。凸轮31的顺时针面提供小的阻力并且一旦凸轮32的顺时针面提供了阻力，操作者应停止旋转帽。
帽现在处于“快装”状态并且一直保持它直到主顾/最终使用者想改变它。
凸轮30的逆时针面防止帽从主体上轻易地移开。实际上如果移动帽将破坏这个面，提供了破坏的痕迹。
如果使用者决定调整装配，他/她旋转帽通过凸轮31的顺时针面的极小的阻力且继续旋转1/4圈通过凸轮33的顺时针面的小的阻力。
现在帽把夹套、间隔垫圈和“O”型环压迫在一起以便形成大的夹紧和“超密封”状态的密封连接。此外，去除了管接头中的任何随意操作并且不可能意外地释放夹套。
为了释放安装，使用者必须首先逆时针旋转帽通过凸轮33和由凸轮31的逆时针面提供的小的阻力，从而回到“快装”位置。用“快装”接头提供的常规方法通过释放夹套可以移开管。
现在参见如图6到11所示的第一变化的实施例，主体上的第一凸轮30由一倾斜的有角度的弹性腿50代替，它与实体凸轮30执行同样的功能。实体凸轮31和33也可由倾斜的有角度的弹性腿代替。此装置在其它方面与图1到5的装置相同并且操作也相同。
图12所示的装置是另一实施例，其中颠倒了主体和帽上凸轮的位置。在管接头体中，形成了一单个倾斜的成角度腿51，它与位于图1到5装置的帽上的形成24的凸轮等同。一对间隔紧挨的凸轮52和53制于帽上其与图1到5装置的凸轮30和31等同，且另一个周向间隔的凸轮54等同于图1到5装置的主体上的凸轮33。帽上的凸轮和接头体上的弹性腿形成了相对于上述的接头体的帽的第一和第二旋转位置。
图12和13表示另一个装置，其中主体上的凸轮30，31和33(未表示)通过与帽上轴向延伸的弹性腿55接合来在接头体上形成上述的帽的第一和第二旋转位置。
图14表示另一个变化，其中接头体形成具有升起凸轮61(只有一个可见)的凸缘60，凸轮61在一端具有小角度斜面62，在另一端具有垂直面63。帽上的弹性腿64能与凸轮接合，通过顺时针旋转帽越过斜面和凸轮并落入远离面63的凸缘60来阻止返回运动。凸缘周向间隔位置有一类似的凸轮来提供帽相对于接头体的第二位置。
图15表示另一个装置，其中在帽的周向间隔处具有窗口70(只有一个可见)且可与接头体上的向外的成角度弹性腿71接合，相对于主体形成帽的两个间隔旋转位置。
