Embodiment 1

[0044] figure 1 , figure 2 and image 3 The shown opening and closing lid structure of the pressure cooker is arranged on the outer surface of the lid 2 of the pressure cooker relative to the pot body 1, and includes connecting rods 4, clamps 3, turntable 5, chassis 7 and other components.

[0045] Such as figure 2 and image 3 Shown, the pot cover 2 center is fixedly connected with a chassis 7 by pivot pin 6. Turntable 5 and chassis 7 are positioned at the central position of pot cover 2 same side. The center of the turntable 5 is provided with a center hole 5d, and the turntable 5 is sleeved on the above-mentioned shaft pin 6 through the center hole 5d. A center torsion spring 11 is arranged between the turntable 5 and the chassis 7, and the center torsion spring 11 is sleeved on the shaft pin 6, and its two feet act on the turntable 5 and the chassis 7 respectively. Specifically, the two legs of the central torsion spring 11 are respectively blocked by the first bos...

Embodiment 2

[0057] Such as Figure 12 As shown, the clamp 3 is hinged on the front end of the connecting rod 4 through the pivot two 9, and a torsion spring 10 is sleeved on the pivot two 9, and the two ends of the torsion spring 10 act on the clamp 3 and the connecting rod 4 respectively. During the swinging process of the clamp 3, its positional relationship with respect to the edge of the pot cover 2 and the pot body 2 is in a changing state. If the angle is not adjusted, only part of the entire clamp 3 can be buckled between the pot cover 2 and the pot body. 1 edge. In this embodiment, the angle of the clamp 3 can be adjusted in time so that it can be tightly fastened to the edge of the pot cover 2 and the pot body 1 . The torsion spring 10 can ensure that the clamp 3 will not disengage after being buckled. In addition, in order to prevent the torsion spring 10 from falling off, a top cap is provided on the top of the pivot 9 for fixing the torsion spring 10 .

Abstract

The present invention is one novel cover opening and closing mechanism for pressure cooker, and relates to daily use article technology. The cover opening and closing mechanism set between the cover and cooker body of pressure cooker includes at least two clamps to buckle the edge of the cover to the cooker body, link rods in the same number as the clamps and hinged to the cover and the clamps, one turntable in the center of the cover capable of shifting the link rods to swing about the hinging point on the cover. The cover opening and closing mechanism makes the pressure cooker possess high work stability, high safety, high reliability, high use flexibility and long service life.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a pressure cooker opening and closing lid structure used on the pressure cooker. Background technique [0002] In order to realize the tight engagement of the pot body and the pot cover so as to safely increase the pressure in the pot, various types of pressure cookers have been designed. According to different closing forms, it can be divided into screw-on pressure cooker, gland-type pressure cooker, drop-cover pressure cooker, clamp-type pressure cooker and so on. [0003] At present, the application range of the screw-on pressure cooker is the most extensive. By rotating the pot cover, the upper and lower teeth of the pot body and the pot cover are snapped together to achieve the purpose of sealing. But the safety performance of the pressure cooker of this structure is difficult to be guaranteed, there is potential safety hazard easily, improper use is prone to acci...
