[0019] 1. The utility model discloses a fixing seat is provided with the top surface of the cover, and the fixing seat is provided with a limiting channel for the leg of torsional spring to pass through and form the limiting to the leg. The limiting channel has first limiting section and second limiting section arranged upwards and downwards, and the second limiting section is located above the first limiting section and has a width smaller than the first limiting section. The first limiting section and the second limiting section have different functions respectively. The first limiting section has a larger width, thereby facilitating the leg to pass through, reducing the risk that the leg cannot pass through due to interference with the fixing seat, ensuring reliable assembly of the leg, reducing assembly difficulty, improving production efficiency and product yield. The second limiting section has a smaller width and is located above. When the torsional spring is stressed, the leg will be raised upwards, thereby naturally entering the second limiting section and being limited by the second limiting section. Due to the limiting by the two side walls of the second limiting section, the leg cannot shake laterally in a large range, thereby enabling the leg to stably abut against the second limiting section, and the application of force is also more stable and reliable, thereby ensuring the stability of the movement of the pot cover during the opening and closing of the cover and reducing the shaking of the pot cover. Meanwhile, the limiting channel is provided as two sections with different sizes, and the overall limiting channel does not need to be accurately sized and processed, thereby greatly reducing the design cost and processing cost.

When the torsional spring is stressed, the supporting leg swings upward, and the amount of upward swing increases as the position approaches the end of the supporting leg. The cross-sectional area of the limiting channel is also designed to increase as the position approaches the end of the supporting leg, so that the contact area between the supporting leg and the limiting channel is larger and the abutment is more stable, and at the same time, the force position of the top wall of the limiting channel is relatively dispersed, the service life is improved, and damage due to stress concentration is avoided.

[0042] like Figure 2 , Figure 3 As shown, a pot lid assembly includes a lid body 1 and a rotating shaft 13 disposed at one end of the lid body 1. A torsion spring 2 is disposed at the rotating shaft 13. The torsion spring 2 has a mounting portion 21 sleeved on the outside of the rotating shaft 13 and a support leg 22 extending to the top of the lid body 1. A fixing seat 5 is disposed on the top surface of the lid body 1. The fixing seat 5 has a limiting channel 51. The support leg 22 passes through the limiting channel 51. The limiting channel 51 has a first limiting segment 511 and a second limiting segment 512 located above the first limiting segment 511. The width of the second limiting segment 512 is smaller than the width of the first limiting segment 511.
[0043] Specifically, such as Figure 1 As shown, the pot lid assembly also includes a top cover 3 located above the lid body 1 and an inner cover 4 located below the lid body 1. The inner cover 4 cooperates with the pot body to form a cooking cavity. The top cover 3 forms the outer surface of the pot lid assembly above the lid body 1 and covers the support legs 22, fixing base 5 and other structures on the top surface of the lid body 1 so that they are not exposed, thus improving the aesthetics of the pot lid assembly.
[0044] In this invention, a fixing seat 5 is provided on the top surface of the cover 1. The fixing seat 5 has a limiting channel 51 for the support leg 22 of the torsion spring 2 to pass through, thereby limiting the support leg 22. The limiting channel 51 has a first limiting section 511 and a second limiting section 512 arranged vertically. The second limiting section 512 is located above the first limiting section 511 and its width is smaller than that of the first limiting section 511. The first limiting section 511 and the second limiting section 512 have different functions. The first limiting section 511 has a larger width, which facilitates the passage of the support leg 22, reduces the risk of interference between the support leg 22 and the fixing seat 5, and ensures reliable assembly of the support leg 22, reduces assembly difficulty, and improves production efficiency and product yield. The second limiting segment 512 is narrower and located at the top. When the torsion spring 2 is under force, the support leg 22 will tilt upwards and naturally enter the second limiting segment 512. Limited by the second limiting segment 512 and its side walls, the support leg 22 cannot sway laterally, allowing it to stably contact the second limiting segment 512. This makes the application of force more stable and reliable, ensuring the stability of the lid's movement during opening and closing and reducing lid shaking. Furthermore, by setting the limiting channel 51 into two segments of different sizes, precise dimensional design and processing of the entire limiting channel 51 are eliminated, significantly reducing design and processing costs.
[0045] Understandably, the torsion spring 2 provides the power for the lid assembly to flip upwards and open. When the lid assembly flips downwards to close, the torsion spring 2 is gradually compressed, and the support leg 22 tilts upwards under the elastic force of the mounting part 21, entering the second limiting section 512. During the process of the lid assembly flipping upwards to open, the support leg 22 is also located within the second limiting section 512, abutting against the top wall of the second limiting section 512 to drive the lid assembly to flip upwards.
[0046] Preferably, the limiting channel 51 extends along the extension direction of the leg 22 to increase the length of the leg 22 extending into the limiting channel 51, thereby improving the limiting effect on the leg 22.
[0047] As a preferred embodiment of this utility model, such as Figure 3 As shown, the outer side of the fixing seat 5 is provided with reinforcing ribs 14, which are connected to the top surface of the cover 1. There are multiple reinforcing ribs 14, which are spaced apart along the extension direction of the limiting channel 51.
[0048] The reinforcing rib 14 is located on the outside of the fixing seat 5, connecting the fixing seat 5 to the top surface of the cover 1, thereby improving the structural strength of the fixing seat 5. Preferably, when the support leg 22 is tilted upward, it abuts against the top wall of the limiting channel 51, thus concentrating the force on the top of the fixing seat 5. Figure 3As shown, the reinforcing ribs 14 extend downward from the top of the fixing seat 5 and are connected to the top surface of the cover 1 to improve the structural strength of the top of the fixing seat 5.
[0049] Meanwhile, the reinforcing ribs 14 are arranged in multiple along the length direction of the limiting channel 51, so that each area of the fixing seat 5 in the length direction has high structural strength.
[0050] In a preferred embodiment, as shown in Figure 2 , Figure 3 , the top surface of the cover 1 is provided with a surrounding rib 15 protruding upward, the surrounding rib 15 surrounds the exhaust channel, and at least part of the reinforcing ribs 14 extend toward the surrounding rib 15 to be connected to the surrounding rib 15.
[0051] The reinforcing ribs 14 are connected to the cover 1, which can improve the strength of the fixing seat 5 to make the fixing seat 5 stably abut against the leg 22. Meanwhile, the reinforcing ribs 14 are connected to the surrounding rib 15 surrounding the exhaust channel, so that the fixing seat 5 and the surrounding rib 15 form an integrated structure, thereby further improving the structural strength of the fixing seat 5 and reducing the risk of deformation or damage of the fixing seat 5.
[0052] Specifically, as shown in Figure 2 , the torsional spring 2 is two, the mounting portions 21 of the two torsional springs 2 are sleeved on both ends of the rotating shaft 13, the legs 22 of the two torsional springs 2 are respectively located on the left and right sides of the surrounding rib 15, the fixing seat 5 is also two and is located on both sides of the surrounding rib 15, the outer sides of the two fixing seats 5 are provided with reinforcing ribs 14, and at least part of the reinforcing ribs 14 extend from both sides to the surrounding rib 15 to be connected to the surrounding rib 15.
[0053] Specifically, as shown in Figure 3 , the reinforcing ribs 14 are provided with three in the extension direction of the fixing seat 5, and the outer two reinforcing ribs 14 extend toward the surrounding rib 15 to be connected to the surrounding rib 15. Of course, the reinforcing ribs 14 can also be other quantities, and any number and position of the reinforcing ribs 14 can be connected to the surrounding rib 15, which is not limited herein.
[0054] Preferably, as shown in Figure 2 , Figure 3 , Figure 4 , the top surface of the cover 1 is provided with a first reinforcing rib 11 and a second reinforcing rib 12, the first reinforcing rib 11 is parallel to the extension direction of the leg 22, the second reinforcing rib 12 is perpendicular to the first reinforcing rib 11, the first reinforcing rib 11 is multiple, and the reinforcing ribs 14 are connected to at least one first reinforcing rib 11.
[0055] As shown in Figure 2As shown, the first reinforcing ribs 11 and the second reinforcing ribs 12 are both multiple and are staggered arranged on the top surface of the cover body 1, so as to improve the structural strength of the top surface of the cover body 1, meanwhile, at least one first reinforcing rib 11 is connected with the reinforcing convex rib 14, so that the reinforcing convex rib 14 and the first reinforcing rib 11 form an integral whole, thereby being able to resist deformation together and further improving the structural strength of the fixing seat 5.
[0056] As a preferred embodiment of the utility model, as shown in Figure 5 、 Figure 6 As shown, the first limiting section 511 and the second limiting section 512 are provided with a guide transition surface 515 therebetween.
[0057] When the torsional spring 2 is installed, the supporting leg 22 is located in the first limiting section 511, and when the torsional spring 2 is stressed, the end of the supporting leg 22 is upturned under the action of the elastic force, so that the supporting leg 22 moves upward as a whole and enters the second limiting section 512, and the width of the first limiting section 511 is relatively large, so that the supporting leg 22 can be transversely displaced in the first limiting section 511, thereby not being aligned with the second limiting section 512 above, so that the upward movement of the supporting leg 22 is stopped by the top wall of the first limiting section 511 and the supporting leg 22 cannot enter the second limiting section 512. By providing the guide transition surface 515, when the supporting leg 22 is vertically misaligned with the second limiting section 512, the supporting leg 22 will contact the guide transition surface 515 when moving upward, and can slide into the second limiting section 512 under the guidance of the guide transition surface 515, thereby ensuring that the supporting leg 22 can smoothly enter the second extending section and form stable limiting, and improving the reliability of the structural cooperation.
[0058] Specifically, as shown in Figure 6 The side wall of the second limiting section 512 on one side is flush with the side wall of the first extending section on the same side, so that the center of the second limiting section 512 is misaligned with the center of the first limiting section 511, that is, the second limiting section 512 is offset above the first limiting section 511, and the guide transition surface 515 is arranged between the first limiting section 511 and the second limiting section 512 on the other side. Of course, the second limiting section 512 can also be located directly above the first limiting section 511, and the guide transition surface 515 is arranged between the first limiting section 511 and the second limiting section 512 on both sides.
[0059] Preferably, the guide transition surface 515 is an arc surface, and of course can also be an inclined surface or an irregular curved surface, etc., which is not limited here.
[0060] Further, as shown in Figure 6As shown, the second limiting section 512 extends in the height direction, so that the inner walls on both sides of the second limiting section 512 have vertical sections 514. The vertical sections 514 can form stable stop limiting for the supporting leg 22, and limit the supporting leg 22 in the second limiting section 512, so as to avoid the supporting leg 22 sliding into the first limiting section 511 when the torsion spring 2 is stressed.
[0061] In another embodiment, the lower end of the side wall of at least one side of the second limiting section 512 has a limiting protrusion protruding towards the inside of the second limiting section 512, so as to further limit the supporting leg 22 from sliding out of the second limiting section 512.
[0062] Preferably, as shown in the drawings, Figure 6 The top wall of the second limiting section 512 is provided with contact curved surfaces 513 on both sides in the width direction of the limiting channel 51.
[0063] After the supporting leg 22 enters the second limiting section 512, even if the supporting leg 22 is laterally displaced, under the upward force of the supporting leg 22, the contact curved surfaces 513 can guide the supporting leg 22 to slide towards the center of the second limiting section 512, and then keep the supporting leg 22 near the central region of the second limiting section 512, further improve the position stability of the supporting leg 22, so that the position of the force applied to the top wall of the second extending section is more stable, and the stress during the opening and closing of the pot cover is stable.
[0064] As a preferred embodiment, as shown in the drawings, Figure 4 The cross-sectional area of the limiting channel 51 gradually increases towards the end of the supporting leg 22 in the extending direction of the supporting leg 22.
[0065] The limiting channel 51 is provided in the ejection direction in the form of a trumpet mouth, which facilitates the ejection of the mold and prevents the production of defective accessories. At the same time, the cross-sectional area of the limiting channel 51 is larger on the side away from the mounting portion 21 than on the side close to the mounting portion 21, because when the torsion spring 2 is stressed, the supporting leg 22 swings upward, and the amount of upward swing is larger at the position closer to the end of the supporting leg 22. The cross-sectional area of the limiting channel 51 is also designed to be larger closer to the end of the supporting leg 22, so that the contact area of the supporting leg 22 with the limiting channel 51 is larger and the abutment is more stable, and at the same time, the force position of the top wall of the limiting channel 51 is relatively dispersed, the service life is improved, and damage due to stress concentration is avoided.
[0066] It should be noted that the way of increasing the cross-sectional area of the limiting channel 51 can be increasing the height and / or increasing the width, which is not limited here.
[0067] Preferably, as shown in the drawings, Figure 2As shown, the top surface of the cover body 1 is further provided with a limiting rib 16 located between the rotating shaft 13 and the fixed seat 5, and the limiting rib 16 is provided with a limiting groove 161 in which the supporting leg 22 is located, and the width of the limiting groove 161 is smaller than the width of the first limiting section 511.
[0068] The supporting leg 22 is located in the limiting groove 161, and the bottom wall of the limiting groove 161 forms an upward support to the supporting leg 22, so as to increase the stress point of the supporting leg 22 and reduce the risk of bending deformation or fracture of the supporting leg 22 under stress.
[0069] Specifically, as shown in the drawings, Figure 2 The top of the limiting groove 161 has an opening, so that the supporting leg 22 can be directly placed in the limiting groove 161.
[0070] The utility model discloses still a kind of cooking utensils, including pot body, still including above-mentioned pot cover subassembly, cover body 1 is rotatably connected with pot body by rotating shaft 13, torsion spring 2 still has the fixed supporting leg 22 extending downward, and the fixed supporting leg 22 is limitedly matched with pot body.
[0071] The supporting leg 22 of the torsion spring 2 is limitedly matched with the fixed seat 5 on the pot cover, and the fixed supporting leg 22 is limitedly matched with the pot body, so that the torsion spring 2 can apply elastic force to the pot cover assembly when stressed, to drive the pot cover assembly to turn up or turn down.
[0072] Specifically, when the pot cover assembly turns down and closes, the torsion spring 2 is gradually compressed to accumulate elastic force, and the elastic force acts on the pot cover, and after closing, the end of the pot cover assembly away from the rotating shaft 13 is locked with the pot body, so that the pot cover assembly cannot move upward. When the user unlocks the pot cover and the pot body, the elastic force of the torsion spring 2 is released, so that the supporting leg 22 drives the pot cover assembly to turn up and open.
[0073] The utility model does not describe the places that can be realized by using or referring to existing technology.
[0074] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.
[0075] The above merely describes the embodiments of the present application and is not intended to limit the present application.
