Description

Technical Field

[0001] This utility model specifically relates to a tableware rack that can be folded in half for storage on both sides and can be laid flat for placing items. Background Technology

[0002] A multi-layer pot rack is a multi-tiered storage device for kitchen cookware. Its layered design improves space utilization and keeps the kitchen tidy. For example, Chinese utility model patent document CN219353735U discloses a multi-layer pot rack, mainly comprising a base, a vertical frame, and a shelf. The base is connected to the vertical frame via an L-shaped connector. The vertical frame is welded together with vertical plates and connecting rods. The shelf is installed by having its two ends fixed protrusions snap into the fixing grooves of the vertical plate. This prior art design features a detachable structure, allowing assembly through insertion and snap-fit, solving the problem of inconvenient transportation and storage of traditional pot racks.

[0003] However, the prior art still has the following drawbacks: Although the prior art can change the storage capacity by changing the number of mounting shelves, this change is not a change in the working mode of the multi-layer pot rack; the multi-layer pot rack only has one working mode (see the appendix of the disclosed document). Figure 1 This means that the pot rack can only accommodate a limited number of pots when the pot is kept upright. Furthermore, the different shapes of various pots (such as the different diameters and heights of frying pans, woks, and saucepans) make it impossible to place deeper or wider pots stably. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tableware rack that can be folded in half for storage on both sides and can be laid flat to hold items, in order to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tableware rack with foldable double-sided storage and flattened placement functions, characterized in that: it includes a first support frame and a second support frame arranged opposite to each other, and several sets of storage components for placing items are detachably installed on one side of the first support frame and one side of the second support frame, one end of the first support frame and one end of the second support frame are rotatably connected, and the included angle between the other side of the first support frame and the other side of the second support frame can be switched within the range of 0 degrees to 180 degrees.

[0006] By employing the above technical solution, the first and second support frames, which are positioned opposite each other, are rotatably connected at one end, allowing them to rotate relative to each other around the connection point. This enables the cutlery rack to switch between two working modes: "flattened" and "folded." In the flattened state (the angle between the other side of the first support frame (the side without an object) and the other side of the second support frame (the side without an object) is 180 degrees), the left and second support frames provide a larger bottom support area, making it particularly suitable for placing large-diameter flat-bottomed pans or deep soup pots, thus solving the problem of instability of the center of gravity of large pots in the existing vertical structure. In the folded state (the angle between the other side of the first support frame (the side without an object) and the other side of the second support frame (the side without an object) is 0 degrees), not only is the lateral space of the cutlery rack reduced, making it suitable for narrower spaces, but it is also applicable to narrower or lighter soup pots. Furthermore, the detachable connection of the storage units allows for flexible adjustment of the number and location of the units according to actual usage needs, further enhancing flexibility and space utilization.

[0007] The aforementioned foldable, double-sided storage and flattened tableware rack can be further configured such that: a rotating component is provided at the rotatable connection between the first support frame and the second support frame, and the first support frame and / or the second support frame are sleeved on the rotating component by providing a rotatable guide hole structure.

[0008] By adopting the above technical solution, a "rotating component" is set at the rotating connection to provide a supporting axis for the relative rotation of the left and second support frames, making the folding of the two support frames smoother and effectively dispersing the stress during rotation, thus preventing deformation or wear at the support frame connection due to long-term stress. The phrase "the first support frame and / or the second support frame are sleeved on the rotating component by setting a rotating guide hole structure" in this solution specifically includes the following three situations: (i) One end of the first support frame has a first rotating guide hole sleeved on the outer circumference of the rotating component, and one end of the second support frame has a second rotating guide hole sleeved on the outer circumference of the rotating component. (ii) One end of the first support frame has a first rotating guide hole sleeved on the outer circumference of the rotating component, and one end of the rotating component is linked with the second support frame. (iii) One end of the second support frame has a second rotating guide hole sleeved on the outer circumference of the rotating component, and one end of the rotating component is linked with the first support frame. All three situations can achieve a rotatable connection between the first and second support frames; any one of these can be chosen for this technical solution.

[0009] The aforementioned foldable, double-sided storage and flattened tableware rack can be further configured as follows: the rotating component includes a rotating sleeve and a positioning block connected to one end of the rotating sleeve. The other end of the rotating sleeve is provided with several sets of locking blocks protruding outward from the rotating sleeve. The first support frame is fitted onto the outer periphery of the rotating sleeve through a first rotating guide hole, and the second support frame is fitted onto the outer periphery of the rotating sleeve through a second rotating guide hole. The first support frame and the second support frame are distributed between the positioning block and the locking blocks.

[0010] Using the above technical solution, the rotating sleeve serves as the rotation axis, ensuring smooth rotation of the left and second support frames and facilitating operation. The positioning block and the locking block form a bidirectional axial limit, preventing the left and second support frames from slipping during rotation. The independent sleeved design of the first and second rotation guide holes improves coaxiality and flexibility during rotation, adapting to single-sided or double-sided flattening operations.

[0011] The aforementioned foldable, double-sided storage and flattened tableware rack can be further configured as follows: the second support frame is provided with at least one set of rotating connectors at the end facing the first support frame, and the first support frame is provided with a rotating fitting body for each set of rotating connectors. The rotating connector is provided with a positioning groove that penetrates the rotating connector in the middle. The positioning groove divides the rotating connector into a first limiting baffle and a second limiting baffle that are arranged opposite to each other. The rotating fitting body is embedded in the positioning groove and is distributed between the first limiting baffle and the second limiting baffle.

[0012] Using the above technical solution, the positioning groove in the middle of the rotating connector provides an embedded rotation space for the rotating mating body, ensuring a stable and non-offset rotation path. The first and second limiting baffles formed by the positioning groove axially limit the rotating mating body from both sides, effectively preventing it from moving left or right or falling off during rotation. This also avoids relative movement between the first and second support frames during rotation, significantly improving the structural stability and smoothness of the relative rotation of the left and second support frames.

[0013] The aforementioned foldable, double-sided storage and flattened tableware rack can be further configured as follows: the first rotating guide hole extends laterally through the middle of the rotating mating body, the second rotating guide hole extends sequentially through the middle of the first limiting baffle and the middle of the second limiting baffle, the first limiting baffle is provided with an embedded groove that fits the positioning block corresponding to the positioning block, and the second rotating guide hole located in the middle of the second limiting baffle is provided with an annular stepped surface that engages with the locking block.

[0014] By employing the above technical solution, the positioning block is embedded in the inner groove, preventing it from protruding from the surface of the first limiting baffle, thus improving surface smoothness and resulting in a more aesthetically pleasing and neat appearance. Furthermore, the locking structure between the locking block and the annular stepped surface creates an axial limit to the right for the second support frame. Combined with the positioning effect of the inner groove on the left side, this stably limits the left and second support frames to the rotating part, preventing axial slippage.

[0015] The aforementioned foldable double-sided storage and flattening tableware rack can be further configured as follows: the rotating sleeve is hollow inside, and one end of the rotating sleeve is provided with several sets of connecting arms arranged at intervals along the circumference of the rotating sleeve, and the end of each set of connecting arms is integrally formed with a set of locking blocks.

[0016] The above technical solution features a hollow interior for the rotating sleeve, reducing overall weight. Several sets of connecting arms are arranged at intervals; these arms can deform during the installation of the rotating component, facilitating the repositioning and locking of the locking block after passing through the second rotation guide hole during assembly. The connecting arms and locking blocks are integrally molded, enhancing the connection strength and preventing the locking block from falling off. Furthermore, the integral molding process reduces assembly steps and improves production efficiency.

[0017] The aforementioned foldable, double-sided storage and flattened tableware rack can be further configured as follows: the outer periphery of the rotating mating body is provided with at least two sets of spaced rotating limiting blocks, and the inner side of the positioning groove is provided with a groove that can cooperate with a set of rotating limiting blocks.

[0018] Using the above technical solution, in the flattened state, a set of rotating limiting blocks abuts against one end of the positioning groove, limiting the angle of the flattening direction and effectively preventing over-flattening, thus ensuring the support stability when placing items flat. In the folded state, another set of rotating limiting blocks rotates to engage with the groove, locking the folded state through the engagement of the blocks and the groove, preventing the cutlery rack from unfolding on its own due to accidental contact during storage, and improving the support stability in the folded state.

[0019] The aforementioned foldable tableware rack with dual-sided storage and flattening functions can be further configured such that: each side of the first support frame is provided with at least one set of left uprights, and each side of the second support frame is provided with at least one set of right uprights.

[0020] With the above technical solution, when the object is flattened, the left and right uprights form support legs to support the first and second support frames, making the flattened state more stable and preventing it from tipping over when items such as pot lids are placed on it.

[0021] The aforementioned foldable tableware rack with double-sided storage and flattening functions can be further configured as follows: the left upright has a first protruding strip protruding outward on its side, and the right upright has a second protruding strip that is offset from the first protruding strip. When the first support frame or the second support frame is folded around the rotational connection between the two, each set of left uprights is opposite to a set of right uprights, and the second protruding strip is distributed between the first protruding strip and the first support frame.

[0022] Using the above technical solution, when the left and second support frames are folded around the rotating connection, the left and right uprights correspond to each other. The staggered design makes the second protrusion exactly distributed between the first protrusion and the first support frame. Through the engagement of the first protrusion (left upright) and the second protrusion (right upright), a reverse constraint is formed along the folding direction, which effectively prevents the left and second support frames from rotating relative to each other due to external force or their own weight. This keeps the cutlery rack firmly locked in the folded state, avoiding storage failure or increased space occupation caused by accidental flattening.

[0023] The aforementioned foldable, double-sided storage and flattened tableware rack can be further configured as follows: both sides of the first support frame and both sides of the second support frame are respectively provided with mounting structures that can be detachably connected to the items. The mounting structure includes a guide groove, the lower end of the guide groove is provided with a through hole, the end of the item is inserted into the guide groove and extends to the through hole, and the end of the item is provided with a hook that extends out of the through hole and is bent toward the side of the through hole. The guide groove is open toward the center of the first support frame or toward the center of the second support frame; the item is provided with a bent body that protrudes outward.

[0024] By adopting the above technical solution, a guide groove is provided to facilitate quick positioning of the end of the holder. After the holder is installed, it also guides and prevents deflection. After the end of the holder is inserted into the guide groove, the hook extends through the hole and bends to the side, forming a hook-like snap-fit ​​structure. The hook engages with the edge of the through hole to prevent the holder from coming off upwards. The side of the guide groove is open, allowing the holder to be inserted laterally from the inside of the support frame, rather than from the top or bottom, further facilitating the assembly and disassembly of the holder. In the folded state, the bent parts on the two lower holders also form legs, ensuring that the cutlery rack can be stably placed on the table when folded.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 13The foldable cutlery rack shown includes a first support frame 1 and a second support frame 2 arranged opposite each other. Several sets of storage components 3 for placing items are detachably installed on one side of the first support frame 1 and one side of the second support frame 2. One end of the first support frame 1 and one end of the second support frame 2 are rotatably connected. The included angle between the other side of the first support frame 1 and the other side of the second support frame 2 can be switched within a range of 0 degrees to 180 degrees. By rotatably connecting one end of the oppositely arranged first support frame 1 and second support frame 2, they can rotate relative to each other around the connection point, thereby enabling the cutlery rack to switch between two working modes: "flattened storage" and "folded storage". In the flattened state (the angle between the other side of the first support frame 1 (the side without the object 3) and the other side of the second support frame 2 (the side without the object 3) is 180 degrees), the first support frame 1 and the second support frame 2 can provide a larger bottom support area, which is especially suitable for placing large-diameter flat-bottomed pans or deep soup pots, solving the problem of unstable center of gravity of large pots in the existing vertical structure. In the folded state (the angle between the other side of the first support frame 1 (the side without the object 3) and the other side of the second support frame 2 (the side without the object 3) is 0 degrees), not only can the lateral space of the cutlery rack be reduced, making it suitable for narrower spaces, but it can also be used for narrower or lighter soup pots, etc. Furthermore, through the detachable connection of the storage component 3, the number and position of the storage component 3 can be flexibly adjusted according to actual usage needs, further improving the flexibility of use and space utilization.

[0029] A rotating component 4 is provided at the rotatable connection between the first support frame 1 and the second support frame 2. The first support frame 1 and the second support frame 2 are fitted onto the rotating component 4 through a rotation guide hole structure. By providing the rotating component 4 at the rotatable connection, a supporting axis is provided for the relative rotation of the first support frame 1 and the second support frame 2, making the folding of the two support frames smoother, effectively dispersing the stress during the rotation process, and preventing the connection of the support frames from deforming or wearing due to long-term stress.

[0030] The rotating component 4 includes a rotating sleeve 6 and a positioning block 7 connected to one end of the rotating sleeve 6. The other end of the rotating sleeve 6 has several sets of locking blocks 8 protruding outwards. A first support frame 1 is fitted onto the outer circumference of the rotating sleeve 6 through a first rotation guide hole 9, and a second support frame 2 is fitted onto the outer circumference of the rotating sleeve 6 through a second rotation guide hole 10. The first support frame 1 and the second support frame 2 are distributed between the positioning block 7 and the locking blocks 8. The rotating sleeve 6 serves as the rotation axis, ensuring smooth rotation of the first support frame 1 and the second support frame 2, facilitating operation. The positioning block 7 and the locking blocks 8 form a bidirectional axial limit, preventing the first support frame 1 and the second support frame 2 from slipping off during rotation. The independent fitting of the first rotation guide hole 9 and the second rotation guide hole 10 improves coaxiality and flexibility during rotation, adapting to single-sided or double-sided flattening operations.

[0031] The second support frame 2 has a set of rotating connectors 11 at its end facing the first support frame 1. The first support frame 1 has a rotating fitting body 12 corresponding to each set of rotating connectors 11. A positioning groove 13 penetrates the center of each rotating connector 11, dividing it into a first limiting baffle 14 and a second limiting baffle 15 positioned opposite each other. The rotating fitting body 12 is embedded within the positioning groove 13 and is distributed between the first limiting baffle 14 and the second limiting baffle 15. The positioning groove 13 in the center of the rotating connector 11 provides embedded rotation space for the rotating fitting body 12, ensuring a stable rotation path without deviation. The first limiting baffle 14 and the second limiting baffle 15 formed by the positioning groove 13 axially limit the rotating mating body 12 from both sides, effectively preventing it from moving left or right or falling off during rotation. This also avoids relative movement between the first support frame 1 and the second support frame 2 during rotation, significantly improving the structural stability and smoothness of the relative rotation of the first support frame 1 and the second support frame 2.

[0032] The first rotation guide hole 9 extends laterally through the middle of the rotating mating body 12. The second rotation guide hole 10 extends sequentially through the middle of the first limiting baffle 14 and the middle of the second limiting baffle 15. The first limiting baffle 14 has an embedded groove 16 corresponding to the positioning block 7. The second rotation guide hole 10 located in the middle of the second limiting baffle 15 has an annular stepped surface 17 that engages with the locking block 8. By embedding the positioning block 7 into the embedded groove 16, the positioning block 7 is prevented from protruding from the surface of the first limiting baffle 14, improving the surface smoothness and making the appearance more beautiful and neat. Furthermore, through the engaging structure of the locking block 8 and the annular stepped surface 17, the second support frame 2 is axially limited to the right. Combined with the positioning effect of the embedded groove 16 on the left side, the first support frame 1 and the second support frame 2 are stably limited on the rotating part 4, preventing axial slippage.

[0033] The rotating sleeve 6 is hollow inside, and one end of the rotating sleeve 6 is provided with several sets of connecting arms 18 arranged at intervals along the circumference of the rotating sleeve 6. The end of each set of connecting arms 18 is integrally formed with a set of locking blocks 8. The hollow interior of the rotating sleeve 6 reduces the overall weight. The several sets of connecting arms 18 are arranged at intervals. When the rotating component 4 is installed, the connecting arms 18 can deform, which facilitates the locking blocks 8 to reset and lock after passing through the second rotation guide hole 10 during assembly. The integral forming of the connecting arms 18 and the locking blocks 8 enhances the connection strength between the locking blocks 8 and the connecting arms 18, prevents the locking blocks 8 from falling off, and the integral forming process reduces assembly steps and improves production efficiency.

[0034] The outer periphery of the rotating mating body 12 is provided with two sets of spaced-apart rotation limiting blocks 19, and the inner side of the positioning groove 13 is provided with a groove 20 that can cooperate with one set of rotation limiting blocks 19. In the flattened state, one set of rotation limiting blocks 19 abuts against one end of the positioning groove 13, limiting the angle of the flattening direction, effectively preventing excessive flattening and ensuring the support stability when placing items. In the folded state, the other set of rotation limiting blocks 19 rotates to engage with the groove 20, and the engagement between the blocks and the groove 20 locks the folded state, preventing the cutlery rack from unfolding on its own due to accidental contact during storage, and improving the support stability in the folded state.

[0035] The first support frame 1 has two sets of left uprights 21 on each side, and the second support frame 2 has two sets of right uprights 22 on each side. When flattened, the left uprights 21 and right uprights 22 form supports to hold the first support frame 1 and the second support frame 2, making the flattened state more stable and preventing it from tipping over when items such as pot lids are placed on it.

[0036] The left upright 21 has a first protruding strip 23 protruding outward on its side, and the right upright 22 has a second protruding strip 24 that is offset from the first protruding strip 23. When the first support frame 1 or the second support frame 2 is folded around the rotating connection between the two, each set of left uprights 21 is opposite to a set of right uprights 22, and the second protruding strip 24 is distributed between the first protruding strip 23 and the first support frame 1. When the first support frame 1 and the second support frame 2 are folded around the rotating connection, the left uprights 21 and the right uprights 22 correspond to each other. The offset design makes the second protruding strip 24 exactly distributed between the first protruding strip 23 and the first support frame 1. Through the engagement of the first protruding strip 23 (left upright 21) and the second protruding strip 24 (right upright 22), a reverse constraint is formed along the folding direction, which effectively prevents the relative rotation of the first support frame 1 and the second support frame 2 due to external force or their own weight, thereby firmly locking the cutlery rack in the folded state and avoiding storage failure or increased space occupation caused by accidental flattening.

[0037] Both sides of the first support frame 1 and both sides of the second support frame 2 are provided with mounting structures that can be detachably connected to the placement component 3. The mounting structure includes a guide groove 25, with a through hole 26 at the lower end of the guide groove 25. The end of the placement component 3 is inserted into the guide groove 25 and extends to the through hole 26. The end of the placement component 3 is provided with a hook 27 that extends out of the through hole 26 and is bent towards the side of the through hole 26. The guide groove 25 is open towards the center of the first support frame 1 or towards the center of the second support frame 2. The placement component 3 is provided with a bent body 5 that protrudes outward. The guide groove 25 facilitates quick positioning of the end of the placement component 3. After the placement component 3 is installed, it can also guide and prevent deflection. After the end of the placement component 3 is inserted into the guide groove 25, the hook 27 extends out of the through hole 26 and bends to the side to form a buckle structure similar to a "barb". The hook 27 is engaged with the edge of the through hole 26 to prevent the placement component 3 from coming off upward. The guide groove 25 has an open side, allowing the item 3 to be inserted laterally into the guide groove 25 from the inside of the support frame, rather than from the top or bottom, further facilitating the assembly and disassembly of the item 3. In the folded state, the bent bodies 5 on the two lower item 3 can also form legs, ensuring that the cutlery rack can be stably placed on the table in the folded state.

[0038] From the appendix Figure 2 As shown, in the "flattened state," the first support frame 1 and the second support frame 2 rotate relative to each other around their rotational connection point until fully unfolded. The left upright 21 and the right upright 22 form double-sided support legs, providing stable support through the contact plane at the bottom of the uprights to prevent tipping over in the flattened state. A set of rotation limit blocks 19 on the outer periphery of the rotating mating body 12 abut against one end of the positioning groove 13, limiting the angle of the flattening direction and preventing excessive flattening that could lead to structural imbalance.

[0039] From the appendix Figure 1 As shown, in the "folded state," the first support frame 1 and the second support frame 2 are folded together around the rotatable connection. Another set of rotatable limiting blocks 19 on the outer periphery of the rotatable mating body 12 rotates into the groove 20 inside the positioning groove 13, achieving angle locking of the folded state through mechanical engagement to prevent accidental flattening. The first protrusion 23 of the left upright 21 and the second protrusion 24 of the right upright 22 are staggered. After folding, the second protrusion 24 engages between the first protrusion 23 and the first support frame 1, forming a reverse constraint along the folding direction, further locking the first support frame 1 and the second support frame 2. The bent body 5 on the item holder 3 forms a bottom support leg in the folded state, which, together with the left upright 21 and the right upright 22, supports the cutlery rack, ensuring that it is stably placed on the table after folding and preventing it from tipping over.

[0040] This embodiment has the following advantages: The first support frame 1 and the second support frame 2 rotate relative to each other around the rotating connection point, realizing the switching between two working modes: "flattened placement" and "folded placement". In the flattened state, the first support frame 1 and the second support frame 2 are fully extended, and the left upright 21 and the right upright 22 form double-sided support legs. Together with several sets of detachable and installable storage components 3, they provide multi-layer storage space, suitable for large-diameter flat-bottomed pans or deep soup pots, solving the problem of instability of the center of gravity of large pots in traditional vertical structures. In the folded state, the first support frame 1 and the second support frame 2 are folded together, which not only reduces the horizontal space, but also allows for the placement of narrower or lighter items such as soup pots through the storage components 3. At this time, the bent body 5 on the storage component 3 forms the bottom support leg, which, together with the left upright 21 and the right upright 22, provides support, ensuring that the tableware rack can be stably placed on the table in the folded state.
