Description

Technical Field

[0001] This application relates to the field of cooking utensil accessories technology, specifically to a stand-up pot lid assembly. Background Technology

[0002] During cooking, it's necessary to remove and place the lid to observe the food's condition or add seasonings. Most mainstream cooking appliances on the market use a stand-up lid design, which, by incorporating a handle on the lid body, allows the lid to be placed at an angle or upright, improving ease of use. However, the connection structure between the handle and the lid body in existing stand-up lids still has significant flaws.

[0003] There are two main types of installation methods for stand-up handle components and covers: one is to install the stand-up handle component in the center of the cover, and the other is to install it on the side of the cover. The center installation typically uses a single screw for fixation. While the assembly process is simple, the single-screw connection lacks an anti-rotation limiting structure, causing the stand-up handle component to easily rotate around the screw's axis during use. Prolonged rotation can loosen the connection between the screw and the cover, and in severe cases, the stand-up handle component may detach from the cover, posing a significant safety hazard. To address the rotation issue, side-mounted designs typically employ two or more screws for fixation. The multiple screws act as a limiting force, preventing the upright handle assembly from rotating. However, this installation method significantly increases assembly difficulty: firstly, the screws must be precisely aligned with the various mounting holes on the cover and handle, requiring repeated adjustments during assembly, reducing production efficiency; secondly, if the handle is made of wood, internal and external threaded nuts must be pre-installed inside to engage with the screws for tightening. However, wood has relatively low structural strength, and when tightening the screws, the axial tension on the nut can easily pull the nut off the wooden handle, causing permanent damage to the handle assembly, making reassembly impossible, and increasing after-sales costs and user wear and tear.

[0004] Furthermore, existing stand-up handle assemblies often include a rigid washer between the handle and the upper surface of the lid. The washer contacts the lid in either a full fit or a partial hard contact. Because different models and specifications of pot lids have varying curvatures, the washer can only fit lids with specific curvatures and is not universally compatible. If forcibly installed on a lid with a mismatched curvature, the washer and lid will form localized point or line contact, leading to concentrated stress. When tightening the screws, the tightening force is directly transmitted to the nut inside the handle and the lid. For the lid, rigid stress can easily cause cracks around the mounting holes. For the nut inside the handle, continuous rigid tension will accelerate the detachment of the nut from the wooden handle, further shortening the lifespan of the handle assembly. Utility Model Content

[0005] The purpose of this application is to provide a pot lid assembly that overcomes the shortcomings of existing pot lid assemblies, such as inconvenient installation, easy loosening and falling off, poor lid compatibility, and high safety risks.

[0006] The technical solution adopted in this application is as follows:

[0007] A stand-up pot lid assembly includes a lid body, fasteners, and a handle assembly. The handle assembly is disposed on the outer surface of the lid body and includes a handle and a connecting seat. The handle has a threaded connection portion, and the connecting seat has a support portion. The support portion contacts the outer surface of the lid body and together with the lid body, forms a buffer space. The connecting seat has a connecting channel for the fastener to pass through, and the lid body has a mounting hole corresponding to the connecting channel. The fastener is configured to pass through the mounting hole and the connecting channel from the inside of the lid body and engage with the threaded connection portion for locking. The buffer space is constructed to allow the connecting seat to undergo elastic deformation toward the lid body under the locking action of the fastener.

[0008] In this technical solution, a connecting seat is added between the cover and the handle, and a support is provided on the connecting seat. A buffer space is formed between the support and the outer surface of the cover. The elastic deformation capability provided by the buffer space offsets part of the tension on the threaded connection when the fastener is tightened, reducing the risk of damage to the threaded connection, especially reducing the risk of the threaded connection formed by the embedded nut being pulled off the wooden handle. The buffer space formed by the support and the cover means that the connecting seat does not need to be completely fitted to the cover. With its elastic deformation, it can adapt to the surface of the cover with different curvatures, breaking the strict limitation of the traditional connecting seat on the curvature of the cover and expanding the applicability of the handle assembly. At the same time, the elastic deformation can disperse the pressure on the cover when the fastener is tightened, reduce local stress concentration, reduce cracks around the mounting holes caused by uneven stress on the cover, and especially reduce the risk of the glass cover breaking, thus improving the safety of use.

[0009] The support portion is configured as a ring structure surrounding the connecting channel.

[0010] In this technical solution, the support is constructed as a ring structure surrounding the connecting channel. This design allows the force generated when the fastener is tightened to be evenly transmitted to the cover through the ring structure, avoiding excessive local stress and further reducing the risk of cover breakage and uneven deformation of the connecting seat. At the same time, the ring structure can ensure that the buffer space is evenly distributed along the circumference of the connecting channel, ensuring the consistency of elastic deformation of the connecting seat in all directions, avoiding assembly offset caused by uneven buffer space, and improving the stability of component installation.

[0011] The support portion is integrally formed with the body of the connecting seat, and the support portion is a folded edge structure that folds from the edge of the connecting seat toward the cover.

[0012] In this technical solution, the one-piece molding design eliminates the assembly process of the support and the connecting seat, reducing production complexity. Compared with the splicing structure, the folded edge structure can improve the connection strength between the support and the connecting seat, prevent the support from falling off, extend the service life of the component, and the structural characteristics of the folded edge make it have a more stable elastic deformation capability. Compared with the ordinary flat support, the folded edge can deform more smoothly when under force, further enhancing the tensile force offsetting effect on the threaded connection and strengthening the anti-nut falling off function.

[0013] The connector is provided with a reinforcing protrusion that rises toward the handle.

[0014] In this technical solution, the reinforced protrusion can improve the structural strength of the connector body, prevent the connector from undergoing permanent deformation during long-term use or elastic deformation, and ensure the long-term stability of the component. At the same time, the raised structure can disperse the force transmitted by the fastener to the raised area, reduce the stress on other weak parts of the connector, reduce the risk of connector breakage, and also provide a structural basis for subsequent sleeve assembly.

[0015] The cross-sectional dimension of the central region of the reinforcing protrusion is smaller than the cross-sectional dimension of its two end regions.

[0016] In this technical solution, the cross-sectional dimension of the central region of the protrusion is smaller than that of the two end regions, forming a waist-shaped or hourglass shape. This design further enhances the strength of the connector. At the same time, the structure of the protrusion being narrow in the middle and wide at both ends facilitates the placement of the connection channel, improves the structural compactness, and also facilitates adaptation to the inner walls of other structures, making positioning and installation easier.

[0017] The handle assembly also includes a sleeve disposed between the connecting seat and the handle. The sleeve is fitted over the reinforcing protrusion, and the inner wall shape of the sleeve is adapted to the outer shape of the reinforcing protrusion to restrict relative rotation and radial movement between the sleeve and the connecting seat.

[0018] In this technical solution, a sleeve is added between the handle and the connecting seat. The sleeve's lifting effect increases the distance between the handle and the cover, creating a larger gripping space and improving ease of use. Furthermore, it ensures sufficient distance between the fingers and the cover when the hand is gripping, reducing the risk of fingers coming into contact with the hot cover. The reinforced protrusion's limiting effect prevents the sleeve from shifting during installation or use, ensuring the sleeve's installation position accuracy. Simultaneously, the tight fit between the sleeve and the reinforcing protrusion further enhances the overall structural stability of the connecting seat, preventing localized shaking due to stress and providing more stable support for the handle, thus improving its stability during use.

[0019] The connecting channel is located within the space enclosed by the central region and the two end regions. The inner side of the sleeve is provided with a guide post. The guide post extends into the space enclosed by the central region and the two end regions and corresponds to the position of the connecting channel. The central through hole of the guide post is used to guide the fastener through.

[0020] In this technical solution, the fastener can be aligned with the central through hole of the guide post through the connecting channel, and directly aligned with the threaded connection part under the guidance of the central through hole of the guide post. This solves the problems of difficult screw alignment and easy damage to the screw threads in the prior art, greatly improves assembly efficiency, reduces assembly error rate, and at the same time, the guide post can prevent the fastener from tilting during the insertion process, reduce the friction between the fastener and the connecting channel and the threaded connection part, protect the integrity of the screw threads, and extend the service life of the fastener and the threaded connection part.

[0021] The sleeve abuts against the threaded connection so that when the fastener is locked, the sleeve provides a reverse support force to the threaded connection.

[0022] In this technical solution, the reverse support force of the sleeve further balances the tension of the fastener on the threaded connection, forming a dual protection of elastic buffer and reverse support, reducing the risk of the threaded connection being pulled off the handle, which is especially suitable for wooden handles. At the same time, the reverse support force can ensure that the fastener remains stable after being locked, avoiding the fastener from loosening due to vibration and other factors, improving the overall connection reliability of the component, and reducing the need for later maintenance.

[0023] The threaded connection portion consists of at least two nuts embedded in the handle, and the number of the connecting channel, the mounting hole and the number of nuts are correspondingly provided. The fastener is a screw adapted to the nuts.

[0024] In this technical solution, the combination of multiple nuts and screws, compared with the existing single-screw structure of center mounting, can restrict the handle from rotating around a single axis, solving the defects of easy rotation of the handle and easy loosening of screws in the existing center mounting. At the same time, multiple screws share the locking force, and the tensile force on each nut is greatly reduced, further reducing the risk of nut pull-out. The multi-point connection can also improve the connection stability between the handle and the cover, and prevent the handle from tilting.

[0025] The handle has a connecting end that connects to the cover and a supporting end for standing upright in conjunction with the cover. The two nuts are close to the connecting end and are spaced apart along the direction from the supporting end to the connecting end.

[0026] In this technical solution, the nuts are placed close to the connecting end, making the center of gravity of the handle closer to the lid. When the lid is placed upright through the supporting end, the center of gravity is more stable, preventing the lid from tipping over and solving the problem of instability of existing upright lids. At the same time, the nuts are arranged at intervals along the direction from the supporting end to the connecting end, so that when the handle is subjected to pressure when standing or pulling force when picking it up, the force can be evenly transmitted to the lid through the two nuts, avoiding excessive local force on the handle, which may lead to breakage or deformation.

[0047] In the embodiments of this application, reference is made to Figures 1 to 6 This application provides a stand-up pot lid assembly. For ease of explanation and understanding, the following descriptions are based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is merely a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the stand-up pot lid assembly includes a lid body 1, a fastener 2, and a handle assembly. The handle assembly is disposed on the outer surface of the lid body 1 and includes a handle 3 and a connecting seat 4. The handle 3 has a threaded connection portion, and the connecting seat 4 has a support portion 41. The support portion 41 contacts the outer surface of the lid body 1 and together with the lid body 1, forms a buffer space 5. The connecting seat 4 has a connecting channel 42 through which the fastener 2 passes, and the lid body 1 has a mounting hole 11 corresponding to the connecting channel 42. The fastener 2 is configured to pass through the mounting hole 11 and the connecting channel 42 from the inside of the lid body 1 and is locked in place with the threaded connection portion. The buffer space 5 is constructed to allow the connecting seat 4 to undergo elastic deformation toward the lid body 1 under the locking action of the fastener 2.

[0049] In this application, a connecting seat 4 is added between the cover 1 and the handle 3, and a support part 41 is provided on the connecting seat 4. A buffer space 5 is formed between the support part 41 and the outer surface of the cover 1. During the assembly process, the fastener 2 passes through the inside of the cover 1, which avoids the need to frequently adjust the position of the handle assembly on the outside of the cover 1 to align the screws. During assembly, it is only necessary to first fit the support part 41 of the connecting seat 4 against the outside of the cover 1, ensure that the connecting channel 42 is aligned with the mounting hole 11, and then insert the fastener 2 from the inside, which simplifies the assembly steps.

[0050] In actual use, the elastic deformation capability provided by the buffer space 5 plays a key role: when the fastener 2 is tightened, the connecting seat 4 will produce a slight elastic deformation towards the cover 1. This deformation can offset part of the axial tension of the fastener 2 on the threaded connection. Especially for scenarios where the handle 3 is made of wood, it can effectively alleviate the effect of the screw tension on the nut embedded in the handle 3, and prevent the nut from being pulled off the wooden handle due to excessive tension, thus solving the problem that the nuts of existing wooden handles are easy to fall off and cause permanent damage to the components.

[0051] Meanwhile, the contact between the support part 41 and the cover 1 is not a complete fit, but rather adapts to the surface curvature of the cover 1 through elastic deformation. Even when faced with different models of cover 1 with different curvatures, such as wok lids and soup pot lids, the support part 41 can adjust the contact state through deformation, breaking the limitation of existing rigid gaskets that can only adapt to cover 1s with specific curvatures, thus improving the versatility of the component. In addition, elastic deformation can also disperse the pressure on the cover 1 when the fastener 2 is tightened, avoiding the tightening force from being directly concentrated around the mounting hole 11 of the cover 1, reducing the risk of cracks in the cover 1 due to stress concentration, and especially reducing the risk of the glass cover 1 shattering, thus improving safety in use.

[0052] As a preferred embodiment of this application, such as Figure 4As shown, the support 41 is constructed as an annular structure surrounding the connecting channel 42. During assembly, the annular structure serves as a visual positioning reference, helping operators quickly align the connecting channel 42 with the mounting hole 11 of the cover 1 without repeated position checks, further improving assembly efficiency. From a stress perspective, the annular support 41 is distributed around the connecting channel 42. When the fastener 2 is tightened, the locking force is evenly transmitted to the surface of the cover 1 through the annular structure, avoiding excessive local stress. Compared to existing pads with localized hard contact, the annular contact expands the stress range to the annular area, significantly reducing local stress around the mounting hole 11 of the cover 1, further reducing the risk of cracking of the cover 1. At the same time, the annular structure ensures that the buffer space 5 is evenly distributed circumferentially along the connecting channel 42, ensuring that the elastic deformation of the connecting seat 4 is consistent in all directions when the fastener 2 is tightened. This prevents the connecting seat 4 from tilting due to uneven buffer space 5, ensuring the stability of the connection between the handle assembly and the cover 1, and preventing the handle 3 from shaking during use.

[0053] In a preferred embodiment, the support portion 41 and the connecting seat 4 are integrally formed, and are configured as a folded edge structure that folds from the edge of the connecting seat 4 toward the cover 1. Due to the requirements of creating a buffer space 5, supporting the weight of the handle 3 and the cover 1, and addressing the high-temperature area in contact with the cover 1 during cooking, the connecting seat 4 must simultaneously meet the requirements of elastic deformation capacity, structural strength, and high-temperature resistance. Therefore, stainless steel is the preferred material for the connecting seat 4. From a manufacturing perspective, the integral forming design allows for the one-time processing of the connecting seat 4 and the support portion 41 through a stamping process, eliminating the need for subsequent assembly steps, reducing the number of parts and assembly steps, lowering production complexity and manufacturing costs, and avoiding the potential problem of the support portion 41 detaching from the spliced ​​structure, thus improving the overall structural strength of the connecting seat 4. The folded edge structure gives it superior elastic deformation capability. Compared to ordinary flat support parts, the folded edge can deform smoothly along the folding direction when subjected to the tension of fastener 2, and its deformation recovery is better. It can maintain the elastic buffering effect for a long time, continuously offsetting the tension on the threaded connection and strengthening the anti-nut loosening effect. In addition, the folded edge structure can further reduce the contact area between the support part 41 and the cover 1. When adapting to cover 1 with different curvatures, the edge of the folded edge can more flexibly fit the surface of the cover 1, improving the fitting accuracy and reducing contact wear on the surface of the cover 1.

[0054] As a preferred embodiment of this application, such as Figure 3 and Figure 4As shown, the connecting seat 4 is provided with a reinforcing protrusion 43 that rises towards the handle 3. The reinforcing protrusion 43 serves both structural strength and assembly compatibility. From a structural strength perspective, the reinforcing protrusion 43 increases the local thickness and structural complexity of the connecting seat 4, thereby improving the rigidity and deformation resistance of the connecting seat 4 body. During long-term use, the connecting seat 4 needs to frequently bear the weight of the handle 3 and the pulling force of the user lifting the pot lid. The reinforcing protrusion 43 can reduce the risk of permanent deformation or breakage of the connecting seat 4, extending the service life of the component. From an assembly compatibility perspective, the reinforcing protrusion 43, rising towards the handle 3, can form a transition support structure between the connecting seat 4 and the handle 3, providing a positioning base for the subsequent installation of the sleeve 6. At the same time, the protrusion structure can disperse the pressure transmitted from the handle 3 to the connecting seat 4, preventing damage to the contact area between the connecting seat 4 and the handle 3 due to excessive local stress, and ensuring a stable connection between the two.

[0055] In a preferred embodiment, such as Figure 4 As shown, the cross-sectional dimension of the middle region of the reinforcing protrusion 43 is smaller than that of the two end regions, making the reinforcing protrusion 43 as a waist or hourglass shape. This design further enhances the strength of the connecting seat 4. At the same time, the structure of being narrow in the middle and wide at both ends makes it easier to avoid setting the position of the connecting channel 42, improving the structural compactness. It also makes it easier to adapt to the inner walls of other structures, facilitating positioning and installation.

[0056] Furthermore, such as Figures 1 to 3 as well as Figure 5 and Figure 6As shown, the handle assembly also includes a sleeve 6 disposed between the connecting seat 4 and the handle 3. The sleeve 6 is fitted over the reinforcing protrusion 43, and the inner wall shape of the sleeve 6 is adapted to the outer shape of the reinforcing protrusion 43 to limit relative rotation and radial movement between the sleeve 6 and the connecting seat 4. Adding the sleeve 6 between the handle 3 and the connecting seat 4 increases the distance between the handle 3 and the cover 1 by utilizing the lifting effect of the sleeve 6, facilitating a larger gripping space and improving ease of use. Furthermore, it ensures sufficient distance between the fingers and the cover 1 when the hand is gripping, reducing the risk of fingers contacting the hot cover 1. During assembly, due to the shape-fitting design of the sleeve 6 and the reinforcing protrusion 43, precise positioning of the sleeve 6 can be achieved without additional angle adjustments, preventing sleeve 6 from shifting and ensuring quick and accurate alignment, thus improving assembly efficiency. If the sleeve 6 is misaligned, it will cause the guide post 61 to be misaligned with the connecting channel 42, making it impossible for the screw to align with the threaded connection. The reinforcing protrusion 43 helps prevent the sleeve 6 from shifting during installation or use, ensuring the accuracy of the sleeve 6's installation position. Simultaneously, the tight fit between the sleeve 6 and the reinforcing protrusion 43 further enhances the overall structural stability of the connecting seat 4, preventing localized shaking due to stress and providing more stable support for the handle 3, thus improving the handle 3's stability during use. The sleeve 6 must meet the requirements of structural rigidity, dimensional stability, and lightweight; aluminum alloy is the preferred material.

[0057] Furthermore, such as Figure 4 and Figure 5 As shown, the connecting channel 42 is located within the space enclosed by the central region and the two end regions. A guide post 61 is provided on the inner side of the sleeve 6, extending into the space enclosed by the central region and the two end regions and corresponding to the position of the connecting channel 42. The central through hole of the guide post 61 guides the fastener 2 through. With this design, after the sleeve 6 is fitted onto the reinforcing protrusion 43, the guide post 61 is precisely inserted into the recessed space between the central region and the two end regions and aligned with the connecting channel 42. The reinforcing protrusion 43 abuts against the guide post 61, restricting the radial displacement and rotation of the sleeve 6. The central through hole of the guide post 61 of the reinforcing protrusion 43 provides a precise insertion path for the fastener 2: during assembly, after the screw passes through the mounting hole 11 and the connecting channel 42 from the inside of the cover 1, it can directly enter the threaded connection part along the central through hole of the guide post 61, solving the problems of difficult screw alignment and easy damage to the screw threads in the prior art; at the same time, it avoids screw thread damage caused by screw tilting, reducing the scrap rate of parts. The guide post 61 can limit the insertion direction of the screw, prevent the screw from tilting during the tightening process, ensure the fitting accuracy between the screw and the threaded connection, prevent the connection from loosening due to screw tilting, further improve the connection stability between the handle assembly and the cover 1, and avoid safety hazards caused by screw loosening after long-term use.

[0058] Furthermore, the sleeve 6 abuts against the threaded connection so that when the fastener 2 is tightened, the sleeve 6 provides a reverse support force to the threaded connection. From the perspective of force balance, this design can form "double protection" with the elastic deformation of the connecting seat 4: when the fastener 2 is tightened, the fastener 2 generates a pulling force towards the cover 1 on the threaded connection, while the sleeve 6, through its tight fit with the reinforcing protrusion 43, generates a reverse support force away from the cover 1 on the threaded connection. The two cancel each other out, significantly reducing the net pulling force on the threaded connection. Especially for wooden handles, this effectively prevents the threaded connection formed by the nut from being pulled off the wooden handle due to excessive pulling force. From the perspective of usage stability, the reverse support force can also ensure that the fastener 2 remains stable after being tightened: even if the lid expands and contracts due to temperature changes during cooking, or if the user shakes when handling the lid, the reverse support force can prevent the fastener 2 from loosening, avoid a decrease in the connection strength between the handle assembly and the cover 1, extend the service life of the assembly, and reduce after-sales maintenance needs.

[0059] As a preferred embodiment of this application, such as Figure 1 As shown, the threaded connection consists of at least two nuts 7 embedded within the handle 3. The connecting channel 42 and mounting holes 11 are correspondingly set to the number of nuts 7, and the fastener 2 is a screw adapted to the nuts 7. For wooden handles, it is impossible to directly form a structurally stable thread inside them, so nuts 7 can be embedded inside. After assembly, the end face of the sleeve 6 abuts against the end face of the nut 7 to provide reverse support force for the nut 7. Compared with the existing single-screw structure with center mounting, the design of multiple nuts 7 and screws can limit the rotation of the handle 3 around the screw axis through multiple point limiting. The existing center-mounted handle 3 lacks an anti-rotation structure due to the lack of a single screw, which easily rotates during use, causing the screw to loosen. However, the combination of two or more screws in this design can prevent the handle 3 from rotating, ensuring that the handle 3 always remains stable. Multiple screws share the locking force, and the tension on each nut 7 is only half or less of that in a single screw design, further reducing the risk of the nut 7 being pulled off the handle 3. At the same time, the multi-point connection can distribute the weight of the handle 3 and the pulling force of the user to multiple screws and nuts 7, avoiding the breakage of a single screw due to excessive force, and improving the reliability of the connection.

[0060] Furthermore, such as Figure 1 and Figure 2As shown, the handle 3 has a connecting end 31 that connects to the lid 1 and a supporting end 32 for standing upright with the lid 1. Two nuts 7 are close to the connecting end 31 and are spaced apart along the direction from the supporting end 32 to the connecting end 31. The design of the nuts 7 close to the connecting end 31 allows the center of gravity of the handle 3 to be closer to the lid 1. When the lid is placed upright via the supporting end 32, the center of gravity being closer to the lid 1 prevents the lid from tipping over due to a shift in the center of gravity, solving the problem of existing upright lids easily tipping over. The spaced arrangement of the two nuts 7 along the direction from the supporting end 32 to the connecting end 31 ensures that the supporting force when the lid assembly is upright and the pulling force when lifted are evenly transmitted to the two nuts 7, and then transmitted to the screw and the lid 1 through the nuts 7, preventing the handle 3 from breaking due to excessive local stress. Furthermore, this design forms a configuration where the two nuts 7 are arranged along the length of the handle 3. Compared to the narrow space in the width direction of the handle 3, the arrangement space in the length direction is more ample, facilitating the insertion of the nuts 7 and having less impact on the structural strength of the handle 3.
