Clamp type opening, closing and locking structure of cover of pressure cooker

Abstract

The invention discloses a clamp type opening, closing and locking structure of a cover of a pressure cooker. According to the technical scheme, to overcome the defects that as for an existing clamp type opening and closing structure, the structure is complex, the number of parts and components is large and clamps are abnormally opened frequently, the clamp type opening, closing and locking structure comprises two linkage rods, two clamps and an S-shaped rotating wheel, wherein the rotating wheel comprises an abutting block and two arc baffles, the abutting block comprises two symmetrical locking positions and two symmetrical opening positions, and a guide groove is formed between each locking position and the corresponding arc baffle; the inner end of each linkage rod is provided with a roller matched with the corresponding guide groove for use; the rotating wheel is rotated, so that when the opening positions of the rotating wheel abut against the rollers, the clamps are respectively in an opened state, and when the locking positions of the rotating wheel abut against the rollers, the clamps are respectively in a locking state, and the rollers are located in the guide grooves and limited by the arc baffles. The clamp type opening, closing and locking structure has the advantages that the structure is simple, the number of parts and components is small, and assembly is convenient and rapid; the problem that the clamps break away from working positions because the rollers move outwards due to external force is solved.

Description

technical field [0001] The invention relates to the field of pressure cookers, in particular to a clamp-type opening and closing and locking structure of a pressure cooker lid. Background technique [0002] At present, there are two kinds of opening and closing lid structures of pressure cookers on the market: screw-on type and clamp type. The pressure cooker with the screw-on lid needs to be aligned when the lid is closed, but the position when the lid is closed is difficult to grasp, the operation is difficult, and the safety is relatively poor. Pressure cookers with clamp-type opening and closing lids generally have the problems of complex clamp opening and closing structure, many parts, and cumbersome assembly; when the two clamps are locked, if there is an external force to pull the clamps outward, the clamps will be broken. Abnormal opening also has potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invent...
