Embodiment 1
[0027] Such as Figure 1-7 The fastening structure of a pressure cooking appliance shown includes a pot cover 1, a sealing ring 2, a middle seat 3, a clamp 4 and an inner pot 5, the clamp 4 is connected to the middle seat 3 through a fixed connection, and the inner pot 5 Put it in the middle seat 3.
[0028] The pot cover 1 is circular, and an outward pot cover buckle 1-1 is provided on the outer peripheral surface of the circle. The pot cover buckle 1-1 matches the clamp 4. When the pot cover 1 and the clamp 4 are screwed together To achieve buckling, the lid buckle 1-1 of the pot lid 1 is buckled and connected with the clamp 4, and the pot lid 1 and the inner pot 5 are sealed through the sealing ring 2.
[0029] The lid buckle can be formed by punching the lid itself, or it can be composed of other parts and the lid through welding, riveting, or threaded connection. Similarly, when the lid is oval, it can also use the characteristics of the oval to form a buckle surface , ...

The invention discloses a structure for fastening a pressure cooking utensil, which consists of a pot cover (1) and a pot body. The pot body comprises a middle base or a shell and an inner pot (5) which is arranged in the pot; a sealing ring (2) is arranged between the inner pot and the pot cover; and the pot cover and the pot body are fastened or separated through screwing. The structure is characterized in that: more than two clamps (4) are fixed on the middle base or the edge of the shell along the circumference; the clamps are provided with more than one fastening part; the pot cover (1) is provided with a pot cover buckle (1-1) which is matched with the fastening parts; and when the pot cover (1) and the clamps (4) are fastened in the screwing mode, the pot cover buckle slides into the fastening parts. The pot cover and the clamps have the advantages of simple manufacturing technology, low requirement on the dimensional precision, and low cost. Obvious gaps are not formed on the pot cover, so the user is prevented from being hurt during cleaning. The assembly and use are simple; the inner part of the pot cover and the clamps are convenient to clean; and because the opening ofthe inner pot is not provided with a fastening face, the cover is easy to open or close.
Description
technical field [0001] The invention belongs to the technical field of pressure cooking appliances, and in particular relates to a fastening structure of a cover and an inner pot. Background technique [0002] The pressure cooking utensils currently on the market include a pot lid assembly and a pot body. The pot body includes a middle seat, a base, and an inner pot. The fastening structure of the pot lid and the inner pot is basically as follows: [0003] 1. The mouth of the inner pot is provided with an outward buckle surface, and the mouth of the pot lid is provided with an inward buckle surface. The two are fastened by screwing. The common open flame pressure cooker on the market basically adopts this structure. The disadvantage of this structure is: because the pot cover is provided with an inward buckle surface, it is difficult to clean the inside and the cleaned inward buckle surface is likely to cause injury to the user, and the inner pot mouth is a buckle surface, s...
