Description

Technical Field

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

[0002] In the daily organization of the kitchen, the storage of cookware is often a matter of great concern. Nowadays, many cookware products are equipped with rotating handles, which allow users to easily fold up the handles or adjust them to a more compact position when the cookware is not in use and is stored away.

[0003] However, since the handles of the pot can rotate, they will naturally droop and stick to the pot wall under the influence of gravity. During the heating process, the pot wall will absorb and accumulate heat, and the heat will be transferred from the pot wall to the handles along the contact surface. This will cause the handles to get hot, which will make it very inconvenient to take out and put away the pot, and may even pose a risk of burns. Utility Model Content

The bushing assembly has an axial through hole, the pin assembly is inserted into the axial through hole, the snap ring mechanism is sleeved on the pin assembly, and the outer wall of the snap ring mechanism abuts against the inner wall of the axial through hole to fix the pin assembly to the bushing assembly. The outer wall of the snap ring mechanism is provided with circumferentially extending reinforcing ribs, and the pot lug is fixedly connected to the pin assembly.

[0006] The beneficial effects of this utility model are as follows: the bushing assembly has an axial through hole for insertion; the bushing assembly cooperates with the pin assembly to provide support and rotation; the snap ring mechanism is set between the pin assembly and the bushing assembly for fixing and limiting; the circumferential reinforcing ribs on the outer wall of the snap ring mechanism improve the resistance to deformation, ensure the stability of the snap ring's elastic performance under high temperature conditions, avoid loosening or failure of the connection structure due to thermal expansion, and extend the service life; the reinforcing ribs increase the friction between the snap ring and the bushing assembly, allowing the pin assembly to be adjusted to a suitable angle as needed, and ensuring that the pot ear will not easily rotate due to external force during use; by providing a stable connection and allowing the pin assembly to be fixed at a specific angle, heat transfer problems caused by unstable connection or arbitrary rotation are reduced.

[0009] As a further improvement to the above technical solution, the inner wall of the bushing assembly is provided with a groove that cooperates with the reinforcing rib, and the groove is used to limit the position of the reinforcing rib.

[0010] As a further improvement to the above technical solution, the pin assembly includes a first shaft segment, a second shaft segment, and a third shaft segment arranged coaxially. The second shaft segment is disposed between the first shaft segment and the third shaft segment. The first shaft segment mates with the axial through hole. The diameter of the second shaft segment is larger than the diameter of the first shaft segment, and the diameter of the second shaft segment is smaller than the diameter of the third shaft segment.

[0011] As a further improvement to the above technical solution, a transition cone surface is provided at the end of the first shaft segment away from the second shaft segment, and the diameter of the transition cone surface gradually increases from the end away from the second shaft segment toward the second shaft segment.

[0012] As a further improvement to the above technical solution, the snap ring mechanism and the bushing assembly adopt an H8 / f7 clearance fit.

[0013] As a further improvement to the above technical solution, the retaining ring and the pin assembly form an interference fit of 0.3-0.5mm.

[0014] As a further improvement to the above technical solution, the cross-section of the reinforcing rib is trapezoidal, with the width of its top surface being 0.6-0.8 times the width of its bottom surface, and the spacing between adjacent reinforcing ribs being 1.2-1.5 times the width of the bottom surface of the reinforcing rib.

[0015] A cookware includes a pot body and a connecting structure as described in any of the preceding claims, wherein the bushing assembly is fixed to the pot body.

[0016] The beneficial effects of this utility model are as follows: by adopting an optimized connection structure, the pot ears can rotate more smoothly and flexibly, improving the convenience of user operation and making the adjustment and control of mechanical parts easier; the strengthening rib design and reasonable fitting gap in the connection structure and other optimization measures enhance the stability of the connection between the pot ears and the pot body, making the pot ears more stable when subjected to external forces and vibrations, and reducing the risk of failure caused by structural loosening.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of this utility model, not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] When storing cookware, the rotating handles 400 on the cookware can be folded or adjusted to a more compact position, thereby saving kitchen space and making the kitchen more tidy and organized. Users can easily store cookware in cabinets or shelves as needed without worrying about the handles 400 protruding or taking up extra space.

[0025] However, during the heating process, the pot wall absorbs and accumulates heat. The rotating pot handle 400 hangs down naturally under the action of gravity and sticks to the pot wall. Heat will be transferred from the pot wall to the pot handle 400 along the contact surface. This will cause the pot handle 400 to get hot, making it inconvenient for users to take out and put away the pot, and even posing a risk of burns.

[0026] Therefore, this utility model proposes a connection structure, referring to... Figures 1-3It includes a pin assembly 200, a bushing assembly 100, a snap ring mechanism 300, and a pot ear 400. The bushing assembly 100 has an axial through hole. The pin assembly 200 is inserted into the axial through hole. The snap ring mechanism 300 is sleeved on the pin assembly 200. The outer wall of the snap ring mechanism 300 abuts against the inner wall of the axial through hole to fix the pin assembly 200 to the bushing assembly 100. The outer wall of the snap ring mechanism 300 is provided with a circumferentially extending reinforcing rib 310. The pot ear 400 is fixedly connected to the pin assembly 200. The bushing assembly 100 has an axial through hole for insertion; the bushing assembly 100 cooperates with the pin assembly 200 to provide support and rotation; the snap ring mechanism 300 is disposed between the pin assembly 200 and the bushing assembly 100 for fixing and limiting; the circumferential reinforcing rib 310 on the outer wall of the snap ring mechanism 300 improves the resistance to deformation, ensures the stability of the snap ring's elastic performance under high temperature conditions, avoids loosening or failure of the connection structure due to thermal expansion, and extends service life; the reinforcing rib 310 increases the friction between the snap ring and the bushing assembly 100, allowing the pin assembly 200 to be adjusted to a suitable angle as needed, and ensuring that the pot ear 400 will not easily rotate due to external force during use; by providing a stable connection and allowing the pin assembly 200 to be fixed at a specific angle, heat transfer problems caused by unstable connection or arbitrary rotation are reduced.

[0027] During the installation of the connecting structure, firstly, the pot lug 400 is fixedly connected to the pin assembly 200; the snap ring mechanism 300 is correctly fitted onto the pin assembly 200 to ensure that the snap ring mechanism 300 can correctly fix and limit the pin assembly 200; the pot body is fixedly connected to the bushing assembly 100; the pin assembly 200 is aligned with the corresponding position of the axial through hole, and then the pin assembly 200 is inserted to ensure that the fit between the pin assembly 200 and the bushing assembly 100 is tight and smooth; the angle of the rotating handle is changed by adjusting the position of the pin assembly 200 in the bushing assembly 100 as needed; during the adjustment process, the reinforcing rib 310 increases the friction between the snap ring and the bushing assembly 100 to ensure the stability of the pin assembly 200 at a specific angle; after the assembly is completed, check whether the snap ring mechanism 300 firmly fixes the pin assembly 200 and whether it can rotate smoothly within the required range.

[0028] The pin assembly 200 is prone to accidental sliding in the circumferential direction, altering the position of the pot lug 400. Therefore, in one embodiment, the reinforcing rib 310 includes a plurality of ribs 311 arranged in a circumferential array along the outer wall of the snap ring mechanism 300. The circumferential array of ribs 311 increases the circumferential friction between the snap ring and the bushing assembly 100, allowing the pin assembly 200 to be more securely held in position after being adjusted to a suitable angle, making it less prone to rotation due to external forces.

[0029] The pin assembly 200 is prone to accidental sliding or movement in the axial direction, which can affect the stability and reliability of the connection. Especially when subjected to external forces such as vibration or impact, the pin assembly 200 may loosen or fall off, leading to malfunction. Therefore, in one embodiment, a plurality of reinforcing ribs 310 are provided on the outer wall of the snap ring mechanism 300, and the reinforcing ribs 310 are arranged in an array along the axial direction of the snap ring mechanism 300. The arrayed reinforcing ribs 310 increase the axial friction between the snap ring and the bushing assembly 100, preventing accidental sliding or movement of the pin assembly 200 in the axial direction, thereby improving the stability and reliability of the connection.

[0030] When subjected to external forces, the connection is more prone to relative movement or rotation, leading to instability. Therefore, in one embodiment, the inner wall of the bushing assembly 100 is provided with a groove 110 that mates with the reinforcing rib 310, the groove 110 serving to limit the movement of the reinforcing rib 310. The engagement of the groove 110 and the reinforcing rib 310 creates multiple friction pairs between the retaining spring mechanism 300 and the bushing assembly 100, increasing the contact area and improving the uniformity and stability of the frictional force, thereby significantly enhancing the torque-bearing capacity of the connection. In a vibration environment, the design of multiple friction pairs effectively reduces connection loosening caused by vibration, and the tight fit between the reinforcing rib 310 and the groove 110 absorbs and disperses vibration energy, thus reducing the risk of connection failure.

[0031] The heat from the bushing assembly 100 will spread towards the pin assembly 200 via thermal conduction along the contact interface between the two components. Therefore, in one embodiment, the pin assembly 200 includes a first shaft segment 210, a second shaft segment 220, and a third shaft segment 230 coaxially arranged. The second shaft segment 220 is disposed between the first shaft segment 210 and the third shaft segment 230. The first shaft segment 210 mates with the axial through hole. The diameter of the second shaft segment 220 is larger than the diameter of the first shaft segment 210, and the diameter of the second shaft segment 220 is smaller than the diameter of the third shaft segment 230. The stepped shaft design extends the heat conduction path. Due to the diameter difference between the different shaft segments, heat needs to cross different interfaces during transfer, which increases thermal resistance and helps reduce heat conduction efficiency. When subjected to external forces, the diameter difference between the different shaft segments can disperse stress, reduce stress concentration, and help improve the load-bearing capacity and service life of the connection structure.

[0032] During insertion, the material of the bushing assembly 100 or the pin assembly 200 may be damaged, such as scratched, indented, or deformed, which may reduce the strength and durability of the connection structure and increase the risk of failure. Therefore, in one embodiment, the end of the first shaft segment 210 away from the second shaft segment 220 is provided with a transition cone surface, the diameter of which gradually increases from the end away from the second shaft segment 220 toward the second shaft segment 220. This forms a smooth transition area, guiding the pin assembly 200 smoothly into the bushing assembly 100 and reducing connection problems caused by improper installation.

[0033] Improper fit can lead to increased connection problems, such as loosening, jamming, or wear, affecting normal operation and potentially accelerating component damage. Therefore, in one embodiment, the snap ring mechanism 300 and the bushing assembly 100 employ an H8 / f7 clearance fit. The H8 / f7 clearance fit has a smaller gap, resulting in a tighter fit between the snap ring mechanism 300 and the bushing assembly 100, improving assembly accuracy and reducing connection problems caused by improper fit. In harsh environments such as high temperature or high pressure, mechanical components are prone to thermal expansion or deformation; the clearance between the snap ring mechanism 300 and the bushing assembly 100 can accommodate dimensional changes caused by thermal expansion or deformation.

[0034] The connection between the retaining ring and the pin assembly 200 may not be tight enough, potentially leading to loosening or detachment, affecting the stability and reliability of the connection. Therefore, in one embodiment, the retaining ring and the pin assembly 200 form an interference fit of 0.3-0.5 mm. This 0.3-0.5 mm interference fit ensures a tight connection between the retaining ring and the pin assembly 200, while avoiding assembly difficulties and stress concentration problems caused by excessive tightness. The interference fit also generates additional friction between the retaining ring and the pin assembly 200, helping to prevent loosening and detachment, thereby improving connection strength.

[0035] In one embodiment, the reinforcing rib 310 has a trapezoidal cross-section, with its top width being 0.6-0.8 times the bottom width, and the spacing between adjacent reinforcing ribs 310 being 1.2-1.5 times the bottom width of the reinforcing rib 310. The trapezoidal cross-section of the reinforcing rib 310 can more effectively distribute and bear stress; the top width of the trapezoid is set to 0.6-0.8 times the bottom width, optimizing material utilization and reducing weight while ensuring structural strength; the spacing between adjacent reinforcing ribs 310 is set to 1.2-1.5 times the bottom width of the reinforcing rib 310, providing sufficient support while avoiding stress concentration; through reasonable size proportions and spacing design, the reinforcing ribs 310 can better support and reinforce the overall structure.

[0036] A cookware includes a pot body and a bushing assembly 100 fixed to the pot body by the connecting structure as described in any of the preceding claims.

[0037] By adopting an optimized connection structure, the two ends of the pot ear 400 are fixedly connected by two pin assemblies 200, and the two bushing assemblies 100 are fixed to the pot body. The snap ring mechanism 300 fixes and limits the bushing assemblies 100 and the pin assemblies 200. This allows the pot ear 400 to rotate more smoothly and flexibly, improving the convenience of user operation and making the adjustment and control of mechanical parts easier. The design of the reinforcing rib 310 and the reasonable fit clearance in the connection structure enhance the stability of the connection between the pot ear 400 and the pot body. The pot ear 400 is more stable when subjected to external forces and vibrations, reducing the risk of failure due to structural loosening.

[0038] Preferred, refer to Figure 4 Two pin assemblies 200 are fixedly connected to each end of the pot ear 400, and two bushing assemblies 100 are fixed to the pot body. One bushing assembly 100 is fitted into the snap ring mechanism 300 to fix and limit the bushing assembly 100 and the pin assembly 200. The other bushing assembly 100 is inserted into the axial through hole of the pin assembly 200. The hybrid fixing mode of "snap ring fixing + direct insertion" is adopted, which not only ensures the limiting stability of the key node of snap ring side, but also reduces the friction contact surface through the direct insertion design on the other side, so as to reduce the rotation resistance of pot ear 400 and achieve a smoother operation experience. Compared with the double snap ring solution, one snap ring assembly and related installation process are reduced, which can reduce material costs, shorten assembly time, and reduce the number of metal contact parts, which helps to delay the wear cycle.

[0039] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
