When the pot cover 2 rotates to the locking state, the positioning protrusion 35 corresponds to the unlocking section 223 of the positioning groove 22, the clamping seat 24 can extend into the positioning groove 22, and the positioning protrusion 35 is not locked with the locking section 224, so that the pot cover 2 and the supporting cantilever 3 are not fixed. When the lid 2 is rotated to the unlocked state, the positioning protrusion 35 is rotated with respect to the positioning groove 22 to correspond to the locking section 224, and the two are stopped to be engaged, so that the lid 2 and the support cantilever 3 are fixed.

Wherein, as shown in fig. 14, L1 is a gap between the positioning protrusion 35 and the side wall of the locking section 224.

Example 2: in this embodiment, as shown in fig. 1, 2, 7 and 8, the clamping portion is disposed on one side of the pot cover 2 to form the side positioning portion, and the clamping portion and the mating portion cooperate to circumferentially position the pot cover 2.

Specifically, as shown in fig. 1 and 2, the clamping portion is a fixing groove 34, an opening is formed in one lateral side of the fixing groove 34, the matching portion is a fixing protrusion 21 and can rotate with the pot cover 2, when the pot cover 2 rotates from the locking position to the unlocking position, the fixing protrusion 21 gradually approaches the fixing groove 34 and finally slides into the fixing groove 34 from the opening, and is matched with the fixing groove 34 in a clamping manner to achieve fixation.

The fixing between the two is simpler through the clamping fit of the protrusions and the grooves, the operation is simpler, the pot cover 2 is convenient to detach, the pot cover 2 and the supporting cantilever 3 are simply fixed, higher fixing strength and stability are not needed, and the fixing requirement can be completely met by the fit of the fixing protrusions 21 and the fixing grooves 34. Meanwhile, the clamping structure forms the side positioning part, so that the side part of the pot cover 2 can be circumferentially positioned while fixing is realized, the structure is simplified, and the cost is saved.

Of course, the fastening portion may be a fixing protrusion 21, and the corresponding mating portion is a fixing groove 34, which is not limited herein.

As a preferred embodiment of the present utility model, as shown in fig. 1 and 2, the support cantilever 3 extends at least to the central region of the pot cover 2, and the pot cover 2 is further provided with an operation handle 25, and the operation handle 25 is located at the edge region of the pot cover 2.

The supporting cantilever 3 extends to the central area of the pot cover 2, the operating handle 25 deviates from the center of the pot cover 2 and is positioned at the edge of the pot cover 2, so that the operating handle 25 is far away from the rotation center of the pot cover 2, the rotation moment arm is increased, and the user rotates the pot cover 2 more labor-saving. And when the pot cover 2 is lifted through the operation handle 25, the arm of force of the operation handle 25 away from the rotating shaft is also increased, so that a user can rotate the pot cover 2 in the horizontal plane through the operation handle 25 or turn over and lift the pot cover 2, the pot cover is more labor-saving, and the use experience is improved.

Specifically, as shown in fig. 6, the locking teeth 23 have an extension 231 extending along the axial direction of the lid 2, and a stop 232 extending inward in the radial direction of the lid 2, the extension 231 is located outside the teeth 11, the stop 232 is located below the teeth 11, and the stop 232 extends obliquely downward. The pan teeth 11 are in a space surrounded by the extension section 231 and the stop section 232, and the stop section 232 and the pan teeth 11 form a limit in the up-down direction so as to limit the pan cover 2 to be lifted. As shown in fig. 6, the gap between the outer sidewall of the pan tooth 11 and the inner sidewall of the extension 231 forms the second lateral gap L2.

The oblique extension of the stop segment 232 can increase the space for accommodating the pan teeth 11, and reduce the risk of interference between the pan teeth 11 and the locking teeth 23. Preferably, as shown in fig. 6, the locking teeth 23 further have an outward expansion section 233 extending radially outward along the pot cover 2, the outward expansion section 233 is located above the expansion section 231, and arc transition is adopted among the outward expansion section 233, the expansion section 231 and the stop section 232, so that one side of the locking teeth 23, which is matched with the pot teeth 11, is more round and smooth, friction force when the locking teeth are contacted with the pot teeth 11 is reduced, and risk of scratch is reduced.

In a preferred embodiment, as shown in fig. 5, a vertical floating gap 222 is provided between the top wall of the positioning protrusion 35 and the bottom of the positioning groove 22.

In the pressure cooking process, due to the fact that the pressure in the pot is high, the pot cover 2 is in direct contact with the pressure environment in the pot, the pot cover 2 can float upwards under the action of air pressure, a space is reserved for the upward floating of the pot cover 2 due to the existence of the vertical floating gap 222, the pot cover 2 is prevented from pushing upwards to push the supporting cantilever 3, the situation that the supporting cantilever 3 is tilted is avoided, and the position stability of the supporting cantilever 3 is improved.
