The upper part of the pinch plate 2 is provided with a concave push groove 2 b.
The pot cover opening and closing mechanism of the pressure cooker creatively enables the buckling plate to stably and smoothly move linearly along the pot ears through the guide structure.
In the initial state, the buckle plate has the tendency of moving upwards under the action of the elastic jacking component, and the wedge blocks are abutted against the side part of the connecting groove in the initial state. Because the section of the connecting groove is isosceles trapezoid, the locking state is kept between the buckle plate and the pot lug in the state.
The buckle has two positions in the locked state:
when the buckling plate is superposed with the pot ears, the buckling plate is separated from the pot cover at the moment, and the pot cover of the pressure pot is in an unlocking posture;
when the end part of the buckle plate extends out of the end part of the pot lug, the buckle plate is buckled on the pot cover, and the pot cover of the pressure pot is in a locking posture.

Example two
The structure and principle of this embodiment are basically the same as those of the first embodiment, except that:
the concave positioning hole I6 and the concave positioning hole II 7 are formed in the chute 2a of the pinch plate 2, the positioning hole I6 and the positioning hole II 7 are arranged in the front and back direction along the length direction of the chute 2a, and the ball 5 can be embedded in the positioning hole I6 or the positioning hole II 7 after the pinch plate 2 moves, as shown in fig. 6 and 7.
That is to say, after the ball 5 is embedded into the first positioning hole 6 or the second positioning hole 7 under the elastic force of the spring, the moved buckle 2 can be positioned, and the buckle 2 is prevented from continuously sliding.
Meanwhile, when the ball 5 is embedded in the first positioning hole 6 or the second positioning hole 7 under the elastic force of the spring 4, a clicking sound is given, so that an operator can be effectively reminded that the buckle plate 2 is moved in place.
The pinch plate 2 is provided with two sliding grooves 2a, and a first positioning hole 6 and a second positioning hole 7 are formed in the two sliding grooves 2 a. Of course, the two beads 5 can be synchronously embedded in the corresponding first positioning hole 6 or the second positioning hole 7.
Simultaneously, the gib block 1a slope sets up, and buckle 2 can more stable lock on the pot cover after along gib block 1a slope removal. That is, a certain included angle is formed between the moving direction of the buckle 2 and the horizontal direction.
It can be seen that the opening and closing structure mainly depends on the ball embedded in the first or second positioning hole to realize the locking between the buckle plate and the pot ear. The inclined guide strip and the wedge block are matched with the connecting groove to form auxiliary locking.
