Abstract

本发明涉及快速附接的流体喷头。一种用于多组分喷涂器的流体部分或喷头(10)，其能够通过旋转流体喷头1/8圈而容易地与空气部分(12)组装或从空气部分(12)拆除。所述流体喷头(10)具有四个突片(14)，该四个突片(4)凸出并与手柄(12)内的四个底切特征部(16)接合。突片(14)被插入到空气部分(12)的前部(12a)的对应开口(16)并旋转，使得突片(14)保持在唇部(18)后方。软管歧管(24)中的锁定突片部分(20)与手柄(12)中的凹陷特征部(22)配合以防止所述流体部分(10)旋转。

Description

快速附接的流体喷头
本申请是申请号为200980117633.8、申请日为2009年5月14日的名称为“快速附接的流体喷头”的中国专利申请的分案申请。
技术领域
本申请要求2008年5月15日提交的美国专利申请No.61/053430的权益，该申请的内容通过引用合并在此。
背景技术
用于喷涂快速凝固材料如聚氨酯和聚脲的喷枪是众所周知的。因为这些材料凝固得非常快，所以易于采用最少的工具拆卸喷枪或喷涂器以清洗变得得非常重要。
发明内容
本发明的目的是为了开发一种将高压流体部分附接至低压空气部分(手柄)的简单方法。通过旋转流体喷头1/8圈，能容易地将流体部分与空气部分组装或从该空气部分拆除。该流体喷头具有四个突片，该四个突片凸出并与手柄内的四个底切特征部接合。在空气部分(手柄)中的加工出来的特征部通过把旋转限制在1/8圈以防止该流体喷头在组装/拆除过程中的过度旋转。当完全组装好时，在软管歧管中的锁定突片特征部与在手柄中的凹陷特征部配合以防止该流体部分旋转。这种结构使用较少的部件并且容易组装和拆除。
本发明的这些和其它目的和优点将结合附图更加完整的在接下来的描述中呈现，其中在几幅图中相同的附图标记指示相同或相似部件。
附图说明
图1是流体喷头相对空气部分的分解图。
图2示出了在被组装到空气部分的一部分的第一阶段期间的流体喷头。
图3示出了在被组装到空气部分的一部分的下一阶段期间的流体喷头。
图4示出了在有软管歧管的情况下组装到空气部分的流体喷头。
具体实施方式
本发明的流体部分或喷头10通过转动流体喷头1/8圈能够容易地与空气部分12组装或从空气部分12拆除。该流体喷头10具有四个突片14，该突片14凸出并且与手柄12内的四个底切特征部16接合(见图1)。图2示出了突片14被插入到空气部分12的前部12a中的对应开口16，而图3示出了已经旋转空气部分10使得突片14保持在唇部18后方。在空气部分(手柄)12中的加工出来的特征部通过把旋转限制在1/8圈以防止该流体喷头10在组装/拆除过程中的过度旋转。
为了完成组装，在软管歧管24中的锁定突片特征部20与手柄12中的凹入特征部22配合以防止该流体部分10旋转(见图4)。该软管歧管24通过螺栓或其他已知的紧固件26而固定到流体部分12。一旦拧紧后，该歧管24、流体部分10和手柄12便全部被相互固定在一起。当然，拆除与组装相反。螺栓26被移除，这允许软管歧管从流体部分10被拆除。随即，允许流体部分10旋转1/8圈并且与手柄分离。
可以想到的是，在不背离所附权利要求书所限定的本发明的精神和范围的情况下，能够对快速附接的流体喷头做出各种改变和修改。
