Pressure cooker upper hand shank

Abstract

A pressure cooker upper hand shank comprises a hand shank body (A), a button (3), a guard plate (5), a rotatable clamping angle (8) and an opening prevention valve (E), wherein the button (3) is positioned in a button hole (2) in the side end of the hand shank body (A). A clamping groove (4) is formed in the button (3), a clamping angle (6) is arranged on one side of the guard plate (5) and positioned in the clamping groove (4), the opening prevention valve (E) is positioned at the front end of the guard plate (5), the button (3) is fixed on the hand shank body (A) through a positioning shaft (7), the rotatable clamping angle (8) is arranged on the other side of the guard plate (5), and the guard plate (5) and the rotatable clamping angle (8) are positioned in a sliding groove (9) in the hand shank body (A). The pressure cooker upper hand shank overcomes the defects that an existing mechanism is prone to misoperation and has potential safety hazards. The pressure cooker upper hand shank is simple in structure, convenient to operate and high in safety performance and meanwhile reduces machining precision and facilitates production.

Description

technical field [0001] The invention relates to an upper handle of a pressure cooker. Background technique [0002] According to the needs of the actual use of the pressure cooker, the pressure cooker is usually provided with an opening and closing cover mechanism including an upper handle, a lower handle and parts thereof, to control the opening and closing of the pressure cooker. And the opening and closing mechanism usually includes a safety device. The function of the safety device is: when the fastening between the lid and the body of the pressure cooker does not meet the requirements, the pressure in the pot cannot rise; when there is pressure in the pot, the lid cannot be opened. [0003] Existing pressure cooker opening and closing mechanism has many kinds, and concrete operation is also different to some extent during use. Many structures have also been patented. Such as the Chinese patent document discloses a patent called a pressure cooker opening and closing l...

AI Technical Summary

Problems solved by technology

[0004] However, in this solution, when the lid and the body of the pot are not properly fastened, that is, when misoperation occurs, the pressure cooker will be boosted during heating, so there are potential safety hazards

In addition, the above scheme still has the problem that the structure is relatively complicated and it is not particularly convenient to use

In addition, the existing rotatable clip angle is assembled under the safety plate. This installation method makes it easy to generate cumulative errors between the rotatable clip angle and the sliding feet, and it is easy to cause the problem of early return of the safety plate, which is inconvenient to use and easy to damage.
