摘要：【中文】本发明涉及照明领域，具体涉及一种快捷转换式灯头及其安装方法。一种快捷转换式灯头，包括绝缘体和金属壳体，所述绝缘体的一端伸入金属壳体的内部并与金属壳体连接，所述绝缘体与所述金属外壳连接的一端外表面设置有卡块，所述金属外壳的中部设有螺纹，所述绝缘体通过所述卡块卡入所述螺纹中实现与所述金属外壳的连接，所述绝缘体的另一端设置有灯脚。通过设置绝缘体和金属壳体之间卡接，方便绝缘体和金属壳体之间安装形成一个整体，且通过将该灯头安装在灯体上，提高灯头和灯座的匹配性。解决了现有技术中存在的安装不便、灯头与灯座不匹配的问题。 【EN】The invention relates to the field of illumination, in particular to a quick conversion type lamp cap and an installation method thereof. The utility model provides a swift conversion formula lamp holder, includes insulator and metal casing, the one end of insulator stretches into metal casing's inside and is connected with metal casing, the insulator with the one end surface that metal casing is connected is provided with the fixture block, metal casing's middle part is equipped with the screw thread, the insulator passes through the fixture block card is gone into realize in the screw thread with metal casing's connection, the other end of insulator is provided with the lamp base. Through setting up the joint between insulator and the metal casing, make things convenient for the installation to form a whole between insulator and the metal casing, and through installing this lamp holder on the lamp body, improve the matching nature of lamp holder and lamp stand. The problem of the installation that exists among the prior art inconvenient, lamp holder and lamp stand unmatched is solved.
