Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a cookware. Background Technology

[0002] To facilitate moving cookware, cookware is typically equipped with a handle, which users can grip to move the cookware. For easy storage, the handle is usually foldable, allowing it to move relative to the cookware to both a folded and a gripping position. When folded, the handle facilitates storage; when gripped, it facilitates movement. However, current technology often employs complex structures to achieve foldable handles, resulting in higher manufacturing costs. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cookware that simplifies the structure while achieving a foldable handle.

[0004] This utility model provides a cookware, which includes a pot body, a base, and a handle. The base includes a mounting plate, a connecting plate, and a limiting plate. The mounting plate is connected to the pot body. Two connecting plates are spaced apart along a first direction. The connecting plates are formed by bending a portion of the mounting plate along a second direction intersecting the first direction. Connecting holes with axes parallel to the first direction are formed on the surface of the connecting plates. The limiting plate is formed by bending a portion of the connecting plates along a direction intersecting the first direction and has a surface parallel to the first direction. The handle includes a grip portion and two connecting portions spaced apart along the first direction. The grip portion is for the user to hold. The connecting portions have protrusions, and the two protrusions extend into the two connecting holes one-to-one and rotatably engage with the connecting holes. The connecting portions can rotate around an axis parallel to the first direction to a folded position and an unfolded position. When the connecting portion is in the unfolded position, the limiting plate abuts against the connecting portion and restricts the rotation of the connecting portion.

[0005] The cookware provided by this embodiment of the invention has at least the following beneficial effects: The limiting plate is formed by bending the connecting plate, which in turn is formed by bending the mounting plate. The connecting plate is used to rotatably connect with the handle, allowing the handle to rotate to both folded and unfolded positions. This simplifies the structure while enabling the handle to be foldable. When the handle is rotated to the gripping position, the limiting plate restricts the rotation angle. Two spaced protrusions correspond one-to-one with two connecting holes, enhancing the handle's stability and improving the user's grip experience while simplifying the structure.

[0006] In one embodiment of this implementation, a portion of the connecting plate is bent to form a curved plate, and a portion of the curved plate extends to one side of the connecting portion in a direction perpendicular to the first direction. When the connecting portion rotates, it can push the curved plate so that the curved plate undergoes elastic deformation in the first direction and abuts against the curved plate in the first direction.

[0007] In one embodiment of this implementation, the bending plate is formed with a friction surface. The distance between each point on the friction surface and the connecting plate in the first direction increases circumferentially along the axis of rotation. When the connecting part rotates, the connecting part abuts against the friction surface and moves relative to the bending plate along the friction surface.

[0008] In one embodiment of this implementation, a through groove is provided on the bending plate, which divides the bending plate and forms a friction plate and a stop plate on opposite sides of the through groove. When the connecting part rotates, it pushes the friction plate and the stop plate to elastically deform the friction plate and the stop plate. When the connecting part rotates to the unfolded position, the connecting part separates from the stop plate and the stop plate elastically returns to the side of the connecting part perpendicular to the first direction to restrict the connecting part from rotating to the folded position.

[0009] In one embodiment of this implementation, the through slot connects to the connecting hole.

[0010] In one embodiment of this implementation, the thickness of the connecting plate is 1.44mm-2.16mm.

[0011] In one embodiment of this method, the cookware includes a positioning pin, and a mounting hole is provided on the connecting part. The positioning pin passes through the mounting hole, and a portion of the positioning pin protrudes from the mounting hole to form a protrusion.

[0012] In one embodiment of this implementation, the first direction is perpendicular to the second direction.

[0013] In one embodiment of this implementation, the limiting plate is formed with a plate surface perpendicular to the second direction, and the connecting hole is located on one side of the limiting plate along the second direction.

[0014] In one embodiment of this implementation, the pot body has an outer peripheral surface, and the mounting plate has an arc surface that abuts against the outer peripheral surface.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0024] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of a cookware 100 according to one embodiment of the present invention. The present invention provides a cookware 100, which includes a pot body 10, a base 20, and a handle 30. The base 20 includes a mounting plate 21, a connecting plate 22, and a limiting plate 23. The mounting plate 21 is connected to the pot body 10. Two connecting plates 22 are spaced apart along a first direction. The connecting plates 22 are formed by bending a portion of the mounting plate 21 along a second direction intersecting the first direction. Connecting holes 222 with axes parallel to the first direction are formed on the surface of the connecting plates 22. The limiting plate 23 is formed by bending a portion of the connecting plate 22 along a direction intersecting the first direction and has a surface parallel to the first direction. The handle... 30 includes a gripping part 31 and two connecting parts 32 spaced apart along a first direction. The gripping part 31 is for the user to hold. The connecting parts 32 have protrusions 322 formed on them. The two protrusions 322 extend into the two connecting holes 222 in a one-to-one correspondence and are rotatably engaged with the connecting holes 222. The connecting parts 32 can rotate about a pivot parallel to the first direction to a folded position and an unfolded position. When the connecting parts 32 are in the unfolded position, the limiting plate 23 abuts against the connecting parts 32 and can restrict the rotation of the connecting parts 32.

[0025] Specifically, the first direction is parallel to the X direction, and a first bending line and a second bending line are defined. Both the first bending line and the second bending line intersect the X direction, and the first bending line intersects the second bending line. A portion of the mounting plate 21 is bent along the first bending line to form a connecting plate 22. The connecting plate 22 has a plate surface that intersects the X direction, and a connecting hole 222 is formed on the plate surface of the connecting plate 22 that intersects the X direction. A portion of the connecting plate 22 is bent along the second bending line to form a limiting plate 23. The gripping part 31 extends along the X direction, and two connecting parts 32 are respectively provided at both ends of the gripping part 31. One end of the connecting part 32 is connected to the gripping part 31, and the other end is rotatably engaged with the connecting hole 222 through a protrusion 322 about an axis parallel to the X direction.

[0026] Understandably, when the connecting part 32 is in the folded position, it extends along the Z direction. The user can rotate the connecting part 32 around an axis parallel to the X direction by pulling the grip 31 until it abuts against the limiting plate 23, thus transferring the connecting part 32 to the unfolded position. During the rotation of the connecting part 32 away from the folded position towards the unfolded position, the distance between the grip 31 and the pot body 10 increases in the Y direction. When the connecting part 32 is in the unfolded position, its extension direction intersects with the Z direction, and the distance between the connecting part 32 and the pot body 10 allows the user's hand to pass through, facilitating the user's movement of the cookware 100. When the connecting part 32 is in the unfolded position, it abuts against the surface of the limiting plate 23 parallel to the X direction, allowing the limiting plate 23 to provide a circumferential force tangential to the connecting part 32 along the axis of rotation. This restricts the rotation of the connecting part 32 away from the folded position, helping to keep the handle 30 stable when the user pulls the cookware 100 with the handle 30.

[0027] The cookware 100 of this utility model has a limiting plate 23 formed by bending a connecting plate 22, which in turn is formed by bending a mounting plate 21. The connecting plate 22 is used to rotatably connect with the handle 30, allowing the handle 30 to rotate to both a folded and unfolded position. This simplifies the structure while enabling the handle 30 to be folded. When the handle 30 is rotated to the gripping position, the limiting plate 23 restricts the rotation of the handle 30, limiting its rotation angle. Two spaced protrusions 322 correspond one-to-one with two connecting holes 222, enhancing the stability of the handle 30 and improving the user's grip experience while simplifying the structure.

[0028] Please see Figures 2 to 5 , Figure 2 This is a three-dimensional structural schematic diagram of the cookware 100 according to one embodiment of the present utility model; Figure 3 yes Figure 2 An enlarged schematic diagram of part of the structure of the cookware 100; Figure 4 yes Figure 2Side view of the base 20 and handle 30 and other structures; Figure 5 yes Figure 4 A top view of the base 20 and handle 30, etc. In one embodiment of this implementation, a portion of the connecting plate 22 is bent to form a curved plate 221. A portion of the curved plate 221 extends to one side of the connecting portion 32 in a direction perpendicular to the first direction. When the connecting portion 32 rotates, it can push the curved plate 221 so that the curved plate 221 undergoes elastic deformation in the first direction and abuts against the curved plate 221 in the first direction.

[0029] Specifically, the connecting portion 32 is located on one side of the connecting plate 22 along the X direction. The connecting portion 32 has a mating surface 323 opposite to the connecting plate 22. A portion of the connecting plate 22 is bent toward the side of the connecting plate 22 opposite to the connecting portion 32 to form a bent plate 221. When the connecting portion 32 is in the folded position, a portion of the bent plate 221 is located on one side of the connecting portion 32 along the Y direction.

[0030] It is understandable that when the connecting part 32 is in the folded position, part of the bending plate 221 is located on one side of the connecting part 32 along the Y direction. The bending plate 221 will block the rotation of the connecting part 32. During the process of the connecting part 32 rotating from the folded position to the unfolded position, it will abut against the bending plate 221 and push the bending plate 221 to undergo elastic deformation, so that the bending plate 221 will exit from the side of the connecting part 32 along the Y direction, thereby releasing the obstruction of the connecting part 32 to the rotation of the connecting part 32 by the bending plate 221. The elastic force generated by the elastic deformation of the bending plate 221 will make the bending plate 221 abut against the pressing surface 323, so that the connecting part 32 needs to overcome a large friction force when rotating, thereby restricting the rotation of the connecting part 32 from the unfolded position to the folded position. This is beneficial to keep the handle 30 stable in the unfolded position and also helps to improve the user's feel when rotating the handle 30.

[0031] Please see Figures 2 to 5 In one embodiment of this implementation, the bending plate 221 is formed with a friction surface 2211. The distance between each point on the friction surface 2211 and the connecting plate 22 in the first direction increases circumferentially along the axis of rotation. When the connecting part 32 rotates, the connecting part 32 abuts against the friction surface 2211 and moves relative to the bending plate 221 along the friction surface 2211.

[0032] Specifically, the connecting plate 22 has a connecting surface 223 perpendicular to the X direction, a connecting hole 222 is formed on the connecting surface 223, the connecting surface 223 is opposite to the mating surface 323, the friction surface 2211 is connected to the connecting surface 223, the XZ plane is defined as a plane perpendicular to the Y direction, the bending plate 221 is inclined in the X direction so that the intersection of the friction surface 2211 and the XZ plane is inclined in the Z direction and also inclined in the X direction, so that the distance of each point on the friction surface 2211 relative to the connecting surface 223 in the X direction increases circumferentially along the axis of rotation.

[0033] It is understandable that the distance between each point on the friction surface 2211 and the connecting plate 22 in the X direction increases circumferentially along the axis of rotation. When the connecting part 32 rotates, it can gradually push the bending plate 221 to the side of the connecting part 32 along the Y direction. This is beneficial to make the elastic deformation of the bending plate 221 linearly related to the rotation angle of the connecting part 32, so that the friction force of the connecting part 32 on the bending plate 221 is linearly related to the rotation angle of the connecting part 32, thereby improving the feel of the user when turning the handle 30.

[0034] Please see Figures 2 to 5 In one embodiment of this implementation, a through groove 2212 is provided on the bending plate 221. The through groove 2212 divides the bending plate 221, and friction plates 2213 and stop plates 2214 are formed on opposite sides of the through groove 2212, respectively. When the connecting part 32 rotates, it pushes the friction plates 2213 and stop plates 2214 to elastically deform the friction plates 2213 and stop plates 2214. When the connecting part 32 rotates to the unfolded position, the connecting part 32 separates from the stop plates 2214, and the stop plates 2214 elastically return to the side of the connecting part 32 perpendicular to the first direction, so as to restrict the connecting part 32 from rotating to the folded position.

[0035] Specifically, the through groove 2212 penetrates the curved plate 221 along the X direction, so that the curved plate 221 forms a friction plate 2213 and a stop plate 2214 on opposite sides of the through groove 2212, respectively. The friction plate 2213 and the stop plate 2214 are respectively connected to the connecting plate 22, and the friction plate 2213 and the stop plate 2214 can undergo independent elastic deformation. When the connecting part 32 is in the folded position, in the plane perpendicular to the Y direction, the projection of the stop plate 2214 overlaps with the projection of the connecting part 32. During the process of the connecting part 32 rotating from the folded position to the unfolded position, the connecting part 32 abuts against the stop plate 2214 and the friction plate 2213 in turn.

[0036] It is understood that the sidewall of the through groove 2212 forms a stop surface 2215 on the stop plate 2214, and an anti-rotation surface 324 is formed on the connecting part 32. When the connecting part 32 is in the folded position, the anti-rotation surface 324 is parallel to the Z direction, so that when the connecting part 32 moves to the unfolded position, the anti-rotation surface 324 is perpendicular to the Z direction. The stop plate 2214 can elastically return to the side of the connecting part 32 along the Z direction, so that the stop surface 2215 and the anti-rotation surface 324 are opposite to each other and can abut against each other, so as to restrict the handle 30 from rotating from the unfolded position to the folded position.

[0037] Please see Figures 2 to 5 In one embodiment of this implementation, the through groove 2212 is connected to the connecting hole 222.

[0038] Specifically, the through groove 2212 extends from the curved plate 221 to the connecting plate 22 and connects to the connecting hole 222.

[0039] Understandably, this arrangement allows the through groove 2212 and the connecting hole 222 to work together to partially divide the connecting plate 22, enabling the portion of the connecting plate 22 connected to the friction plate 2213 to undergo elastic deformation in conjunction with the friction plate 2213. This reduces the elastic force that the connecting part 32 needs to overcome when pushing the friction plate 2213, thereby mitigating the risk that the handle 30 may be difficult to rotate to the unfolded position due to excessive plate thickness. It should be understood that in some embodiments, when assembling the connecting part 32 and the connecting plate 22, the protrusion 322 can extend from one end of the through groove 2212 and slide along the through groove 2212 to the connecting hole 222, so that the protrusion 322 engages with the connecting hole 222, thus completing the assembly of the connecting part 32 and the connecting plate 22. This arrangement eliminates the need to connect the connecting part 32 and the connecting plate 22 with screws, further simplifying the structure and facilitating the assembly process of the handle 30 and the base 20.

[0040] Please see Figure 4 In one embodiment of this implementation, the thickness of the connecting plate 22 is 1.44mm-2.16mm.

[0041] Specifically, the thickness 'a' of the connecting plate 22 can be 1.44mm, 1.60mm, 1.80mm, 2.00mm, and 2.16mm.

[0042] It is understood that in some embodiments, the mounting plate 21, connecting plate 22, limiting plate 23, and bending plate 221 are obtained from the same sheet material through bending. The mounting plate 21, connecting plate 22, limiting plate 23, and bending plate 221 have the same thickness. When the thickness a of the connecting plate 22 is less than 1.44 mm, the handle 30 cannot be stably connected to the pot body 10, and the elastic force generated when the bending plate 221 undergoes elastic deformation is small, resulting in a poor restriction effect of the bending plate 221 on the rotation of the handle 30. When the thickness a of the connecting plate 22 is greater than 2.16 mm, the manufacturing cost of the base 20 is high, and the bending plate 221 is difficult to bend, making it difficult for the handle 30 to rotate to the unfolded position. The thickness 'a' of the connecting plate 22 is 1.44mm, 1.60mm, 1.80mm, 2.00mm, and 2.16mm. On the one hand, this helps to ensure that the handle 30 is securely connected to the pot body 10 while improving the restriction effect of the bending plate 221 on the rotation of the handle 30. On the other hand, it helps to reduce the manufacturing cost of the base 20 while reducing the risk that the handle 30 is difficult to rotate to the unfolded position.

[0043] Please see Figures 1 to 5In one embodiment of this implementation, the cookware 100 includes a positioning pin, and the connecting part 32 has a mounting hole 321. The positioning pin passes through the mounting hole 321, and a portion of the positioning pin extends out of the mounting hole 321 to form a protrusion 322.

[0044] Specifically, the locating pin extends along the X direction. It is understandable that the protrusion 322 formed by the locating pin allows the locating pin and handle 30 to be manufactured separately, which helps reduce manufacturing costs.

[0045] Please see Figures 1 to 5 In one embodiment of this implementation, the first direction is perpendicular to the second direction.

[0046] Specifically, the first direction is parallel to the X direction, and the second direction is parallel to the Z direction. It can be understood that the first direction and the second direction are perpendicular to each other, which enables the connecting plate 22 to have a plate surface perpendicular to the first direction, and facilitates the opening of connecting holes 222 with axes parallel to the first direction on the plate surface of the connecting plate 22.

[0047] Please see Figures 1 to 5 In one embodiment of this implementation, the limiting plate 23 is formed with a plate surface perpendicular to the second direction, and the connecting hole 222 is located on one side of the limiting plate 23 along the second direction.

[0048] Specifically, the limiting plate 23 forms a shielding surface 231 perpendicular to the vertical direction on the top side of the connecting hole 222.

[0049] Understandably, the pot body 10 can be used to store various seasoning sauces. During the use of the pot 100, the seasoning sauce may splash out. The limiting plate 23 can block the seasoning sauce from entering the connection hole 222 from the top side of the connection hole 222, thereby reducing the risk that the handle 30 will not rotate smoothly due to the seasoning sauce entering the connection hole 222.

[0050] Please see Figure 1 and Figure 5 In one embodiment of this implementation, the pot body 10 has an outer peripheral surface 11, and the mounting plate 21 has an arc surface 211, which abuts against the outer peripheral surface 11.

[0051] Specifically, the axis of the outer peripheral surface 11 coincides with the axis of the arc-shaped surface. Understandably, this arrangement allows the mounting plate 21 to fit more tightly with the pot body 10, which helps to improve the stability of the connection between the mounting plate 21 and the pot body 10, and also helps to improve the aesthetics of the cookware 100.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
