Abstract

本发明涉及压力锅锅盖结构及锅牙截面结构形状，通过材料成形得到截面形状是″匚″形的锅牙结构，″匚″形截面双层材料结构的锅牙三个方向双层材料加强强度，对与其装配的外锅扣边实现″匚″形三面加强紧扣，且与锅牙连接周边加强结构为″「″形，也就是未弯牙时周边为环″「″形，此形状能保证在锅牙成形时″「″形上端双层材料与单层材料过渡处形状不发生位移。″匚″形能防止锅牙失效，所以″匚″形加强锅牙结构的锅盖能防止发生因锅牙失效而致的压力锅安全事故。

Description

一种“匚”形锅牙加强结构的压力锅锅盖
技术领域
本发明涉及一种压力锅锅盖，具体涉及锅牙双层材料加强的截面形状
背景技术
全国的压力锅普及率很高，因锅盖锅牙失效而致的压力安全事故常见报道。本发明是对锅盖与其装配连接配件的关键位锅牙进行双层材料“匚”形加强强度。防止锅牙失效。
发明内容
本发明的目的在于加强压力锅锅盖的锅牙强度。“匚”形加强锅牙三个方向双层材料对与其连接的外锅紧扣，比单层材料锅盖锅牙强度成倍增加。市面普及的压力锅锅盖锅牙为单层材料结构，锅牙在弯曲成形过程中可能存在裂纹、暗伤、暗裂，锅牙强度不足是安全事故重要原因之一。双层材料对锅牙“匚”形加强使之获得双重保险。

图4是与锅牙连接边的剖面放大图。

Claims (3)
