Description

卡口式隐形法兰
(一)技术领域：本实用新型涉及一种连接法兰。具体涉及一种卡口式隐形法兰。主要用于风道的连接。
(二)背景技术：现有的隐形法兰，主要有内部插条式和外部插口式二种结构形式。内部插条式，其H形插条插入左、右法兰中间形成的H形插孔内。这种结构的法兰连接强度好，对连接接口尺寸较小的复合板比较容易，但复合板接口尺寸大时插接比较困难；外部插口式法兰，其插条插置在法兰一侧，大、小尺寸复合板的接口连接均比较容易，但连接强度差。
(三)发明内容：本发明的目的在于提供一种连接强度好，连接又方便的隐形法兰。本发明的技术内容是：一种卡口式隐形法兰，是在左、右法兰的连接侧设置有相应的卡口，卡口内侧顶部设置有卡孔，外侧底部设置有与卡孔相应的卡头，外侧中部设置有卡块，一卡口底部的卡头卡入另一卡口顶部的卡孔中左右定位，二卡口中部的卡块底部接合上下定位。本实用新型连接强度高，插接又方便。
(四)附图说明：
图1为本实用新型的总体结构示意图。
(五)具体实施方式：如图1，一种卡口式隐形法兰，它是在左、右法兰1、4的连接侧设置有相应的卡口2、3，卡口2、3内侧顶部设置有卡孔2-1、3-1，外侧底部设置有与卡孔相应的卡头2-3、3-3，外侧中部设置有卡块2-2、3-2，一卡口2底部的卡头2-3卡入另一卡口3顶部的卡孔3-1中左右定位，二卡口2、3中部的卡块2-2、3-2底部接合上下定位。
