Description

The self-locking pressure cooker

The utility model relates to a kind of civilian self-locking pressure cooker.

Shortcomings such as pressure cooker is easy to use, saves the energy, welcome by consumers in general, but also exists complex structure, and worker's clamp mould is many especially should be noted that its poor stability, blast sometimes, and article fly out and cause casualty accident in pot cover and the pot.

The purpose of this utility model is to provide a kind of pot cover is contained in pot body, the self-locking pressure cooker that pot cover is compressed by pot inner pressure.

Self-locking pressure cooker of the present utility model comprises a pot body, pot cover, handle and safety valve, it is characterized in that turning in its pot edge of described pot body, the pot mouth is Long Circle, described pot cover is the Long Circle similar to the pot mouth, its size is slightly larger than the pot mouth, the minor axis of pot cover (width between Long Circle two straightways) is less than the major diameter (length between Long Circle two circular arcs) of pot mouth, so that pot cover is packed in pot body by the pot mouth, be fixed with the cylinder handle on the pot cover, after pot cover is packed pot body into, rotate pot cover, its handle two ends promptly are stuck in carving on the face of two locking beds being fixed on pot body, pot cover and pot body are fixed, and pot cover is equipped with sealing ring with the periphery that the pot body contacts.

The utility model has the advantages that and utilize pot inner pressure pot cover to be pressed on the pot edge of turning in pot body, pot inner pressure is big more, and pot cover is pressed tightly more, thus safe and reliable, and simple in structure, easy to process, low cost of manufacture.
