Technical Field

[0001] This utility model relates to the field of household goods technology, and in particular to a rotating and folding dish rack. Background Technology

[0002] Dish racks are typically placed directly next to the sink for draining and storage. They mainly consist of plates and a mesh frame. The mesh design effectively drains water from dishes, preventing water stains and ensuring they stay dry and hygienic. They are convenient to use, saving time and effort compared to manually wiping dishes. Furthermore, dish racks allow for easy categorization and storage of tableware, saving countertop space and creating a neater, more organized kitchen, thus improving space utilization.

[0003] In existing dish racks with two or more plates, the plates are typically folded and stored by stretching them horizontally, vertically, or by flipping them over. However, these folding and storage designs of existing dish racks are not innovative enough, lack product distinctiveness, are inconvenient for folding, storage, packaging, and transportation, have unclear functional zoning, and remain relatively large even after folding, resulting in high transportation costs.

[0005] The purpose of this utility model is achieved by the following technical solution: a rotating and folding dish rack, comprising a first plate and a second plate, wherein one end of the first plate and the second plate are hinged together; the rotating and folding surfaces of the first plate and the second plate are respectively provided with a first guide slide post and a first arc-shaped slide groove, and the first guide slide post and the first arc-shaped slide groove are slidably engaged so that the second plate rotates relative to the first plate about the hinge point; when folded, the second plate rotates to overlap with the first plate; when unfolded, the second plate rotates to be horizontal with the first plate, forming a double-layer storage space.

[0006] Furthermore, the outer wall of the first guide slide has an anti-detachment protrusion in the circumferential direction, and the groove wall of the first arc-shaped slide has an anti-detachment groove extending along the sliding fit direction, and the anti-detachment protrusion can be slidably embedded in the anti-detachment groove.

[0007] Furthermore, the two ends of the first arc-shaped slide groove are respectively set as folding position and unfolding position, and the groove walls of the folding position and unfolding position are respectively provided with positioning protrusions for positioning the first guide slide column.

[0008] Furthermore, the hinged portions of the first disc and the second disc are respectively provided with a second arc-shaped sliding groove and a second guide sliding post, and the second guide sliding post slides in cooperation with the second arc-shaped sliding groove when the first disc rotates.

[0009] Furthermore, the hinged portions of the first disc and the second disc are respectively provided with a coaxially arranged pin hole one and a pin hole two. The pin hole one and the pin hole two are connected by a rotating pin. The rotating pin has a pin expansion end and a pin limiting end. The pin expansion end passes through the pin hole two and the pin hole one in sequence, and the pin expansion end expands and engages with the outer end face of the pin hole one, while the pin limiting end limits the pin hole two to its outer end face.

[0010] Furthermore, the rotating folding dish rack also includes a wire mesh frame assembly for placing tableware on the plate. The wire mesh frame assembly has a drain wire mesh and wire mesh support legs. The lower end of the drain wire mesh can be flipped and connected to the holder on the first plate. The upper end of the drain wire mesh is movably connected to the wire mesh support legs. When the wire mesh support legs and the drain wire mesh are folded, they can be stored together on the surface of the first plate. When the wire mesh support legs and the drain wire mesh are unfolded, they can be supported on the surface of the first plate.

[0011] Furthermore, at least two of the draining mesh frames are provided and symmetrically arranged on the card holder of the first plate body, and the side rods of the two draining mesh frames are fitted with cutlery tubes.

[0012] Furthermore, the surface of the first disc is provided with several drain strips, and a water guide groove is formed between two adjacent drain strips.

[0014] Furthermore, the bottom of both the first and second discs is provided with flip-foldable disc feet, and the bottom of the second disc is also provided with a balance support that can be supported on the surface of the first disc.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The first plate and the second plate are rotated and folded together by rotating and sliding. This innovative folding method makes it more convenient to unfold and use the dish rack and to fold and pack it. It is different from the traditional left and right / up and down stretching or flipping method, which improves the product recognition. After folding, the two plates are completely overlapped, reducing the transportation volume by more than 50% and reducing transportation costs. When unfolded, the two plates are placed in layers to separate the tableware, realize the separation of dry and wet or the classification of tableware, and make the functional areas clearer.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] like Figure 1-10As shown, a rotating and folding dish rack can be placed directly next to the sink for draining and storage. It can effectively drain water from dishes, prevent water stains from accumulating, and ensure that dishes are dry and hygienic. It is convenient to use, saving time and effort of manually wiping dishes. It can also conveniently classify and store tableware, save kitchen counter space, make the kitchen more tidy and orderly, and improve space utilization efficiency.

[0041] The rotating folding dish rack includes a first plate body 10 and a second plate body 20. The two are hinged to each other by means of a movable pivot. In this embodiment, one corner of one end of the first plate body 10 and the second plate body 20 is hinged together. Alternatively, the middle part of one end of the first plate body 10 and the second plate body 20 can be hinged together.

[0042] The first disc 10 has a first guide slide post 101 on its rotating folding surface (surface), and the second disc 20 has a first arc-shaped groove 201 on its rotating folding surface (bottom surface). During installation, after the first disc 10 and the second disc 20 are hinged together, their rotating folding surfaces slide relative to each other, allowing the first guide slide post 101 to embed into the first arc-shaped groove 201. The second disc 20 can rotate around the hinge point, and when the second disc 20 rotates horizontally relative to the first disc 10, its first arc-shaped groove 201 can slide on the first guide slide post 101, enabling the second disc 20 to fold or unfold on the first disc 10. When folded, the second disc 20 rotates to overlap with the first disc 10, significantly reducing its volume; when unfolded, the second disc 20 rotates to be horizontal with the first disc 10, forming a double-layered storage space.

[0043] Therefore, the rotation and sliding mechanism enables the first plate 10 and the second plate 20 to be rotated and folded for storage. This innovative folding method makes it more convenient to unfold and use the dish rack and to fold and package it. It is different from the traditional left and right / up and down stretching or flipping method, which improves product recognition. After folding, the two plates completely overlap, reducing the transportation volume by more than 50% and reducing transportation costs. When unfolded, the two plates are used to place tableware in layers, realizing the separation of dry and wet utensils or the classification of tableware, and making the functional areas clearer.

[0044] The first guide slide post 101 is disposed on the surface of the first disc body 10 and located at the other corner of the end where the hinge portion is located. An annular anti-detachment protrusion 1011 is provided on the outer periphery of the first guide slide post 101, and an anti-detachment groove 2011 extending along the sliding direction is formed in the groove wall of the first arc-shaped slide groove 201. During assembly, the anti-detachment protrusion 1011 is embedded in the anti-detachment groove 2011, forming a sliding limit. This prevents the slide post from detaching from the slide groove, ensuring structural stability during the rotation and folding of the first disc body 10 and the second disc body 20; the protrusion and groove cooperate to guide the sliding path, avoiding misalignment and jamming, resulting in smoother rotation and sliding.

[0045] The first arc-shaped slide groove 201 can be formed by an annular rib with one concave side and one convex side at the bottom of the second disc body 20, resulting in a high-strength, one-piece structure. Folding positions 2012 and unfolding positions 2013 are respectively provided at both ends of the first arc-shaped slide groove 2011. Positioning protrusions 2014 are integrally formed on the groove walls of the folding positions 2012 and unfolding positions 2013. When the second disc body 20 rotates, its first arc-shaped slide groove 201 slides on the first guide slide post 101. When the first guide slide post 101 slides into the folding position 2012 or unfolding position 2013, its positioning protrusions 2014 abut against the side wall of the first guide slide post 101, producing a damping positioning effect. This ensures stable and accurate positioning in both folded and unfolded states, preventing accidental sliding. The positioning protrusions 2014 provide tactile feedback when the second disc body 20 slides into position, enhancing the user experience.

[0046] A second arc-shaped groove 102 is provided on the hinge portion of the first disc 10. The second arc-shaped groove 102 is recessed in one part of the first disc 10. A second guide slide post 202 is provided on the hinge portion of the second disc 20. The second guide slide post 202 is protruded in one part of the bottom of the second disc 20. During assembly, the second guide slide post 202 is embedded in the second arc-shaped groove 102. When the second disc 20 rotates, the second guide slide post 202 slides along the second arc-shaped groove 102, further constructing a sliding fit between the second disc 20 and the first disc 10. In this way, by providing the second guide slide post 202 and the second arc-shaped groove 102 on the hinge portions of the first disc 10 and the second disc 20 respectively, a sliding fit structure is further constructed, limiting disc offset, preventing single-point deformation of the hinge portion, enhancing structural stability, dispersing stress at the hinge point, reducing wear risk, and extending service life.

[0047] The hinged connection structure between the first disc 10 and the second disc 20 is further described. The hinged portions of the first disc 10 and the second disc 20 have coaxial pin holes 103 and 203 respectively, and are connected by a rotating pin 40. Specifically, the expansion end 401 of the rotating pin 40 has an elastic function. After the expansion end 401 passes through the pin hole 203 and the pin hole 103 in sequence, the expansion end 401 expands and engages with the outer end face of the pin hole 103. The diameter of the pin limiting end 402 of the rotating pin 40 is larger than that of the pin hole 203, causing the pin limiting end 402 to abut against the outer end face of the pin hole 203. Thus, the first disc 10 and the second disc 20 are rotatably hinged together by the rotating pin 40.

[0048] Therefore, by using a rotating pin 40 to rotate and hinge the first disc 10 and the second disc 20, the expansion and insertion design simplifies the installation steps, eliminates the need for additional fasteners, and achieves the purpose of quick assembly and disassembly; the double fixation of the pin expansion end 401 and the pin limit end 402 ensures the long-term reliability of the hinge part of the first disc 10 and the second disc 20.

[0049] Further description of the mesh frame assembly 30: The mesh frame assembly 30 used in this embodiment includes a drain mesh frame 301 and mesh frame legs 302. Two drain mesh frames 301 are provided, arranged symmetrically like wings when unfolded on the holder 104 of the first plate body 10. The lower end of each drain mesh frame 301 is directly engaged with the holder 104 of the first plate body 10 and can be flipped on the holder 104. The upper end of each drain mesh frame 301 is provided with perforated ear plates for the U-shaped mesh frame legs 302 to pass through. When folded, the mesh frame legs 302 flip inward to the bottom of the drain mesh frame 301, overlapping with the drain mesh frame 301 and stored on the surface of the plate body. When unfolded, the mesh frame legs 302 flip outward and support the surface of the first plate body 10, used to shape the drain mesh frame 301 onto the first plate body 10 for placing tableware.

[0050] Furthermore, cutlery containers 50 can be inserted into the side bars of the two drain racks 301 for storing chopsticks, spoons, and other cutlery. The cutlery containers 50 are easy to assemble with the racks and feature a partitioned design, which facilitates assembly and use while preventing cutlery from getting mixed up. The cutlery containers 50 are also detachable for cleaning, adapting to different usage scenarios and enhancing their versatility.

[0051] Therefore, the space frame assembly 30 can be completely folded to avoid taking up extra space, and the easy assembly between the draining space frame 301 and the space frame support 302 achieves flexible storage; after storage, the space frame assembly 30 is not exposed, reducing the risk of dust accumulation and improving hygiene.

[0052] Both the first tray 10 and the second tray 20 have parallelly arranged drain strips 105 on their surfaces, forming a water guide channel 106 between adjacent drain strips 105. The end of the water guide channel 106 of the first tray 10 has a drain outlet 107, and a drain trough 70 is connected to the bottom of the first tray 10 below the drain outlet 107 to discharge the water collected in the tray. The end of the water guide channel 106 of the second tray 20 has several water outlets 204. Water flows through the water outlets 204 into the first tray 10 first, and then through the first tray 10 to the drain outlets 107 for discharge. Therefore, by rationally arranging the drain strips 105 and the water guide channel 106, the first tray 10 and the second tray 20 achieve efficient drainage and prevent water accumulation and bacterial growth.

[0053] The bottom of both the first disc body 10 and the second disc body 20 is provided with flip-up and foldable disc feet 60, which facilitates balanced support of the two disc bodies and ensures overall stability when unfolded. The disc feet 60 reduce the overall height when folded, adapting to different storage spaces and providing high height adaptability. In addition, a balance support 205 is added to the bottom of the second disc body 20, which supports the surface of the first disc body 10 when unfolded, further improving the assembly stability of the first disc body 10 on the second disc body 20 and making the structure more stable.

[0054] Overall, this solution comprehensively solves the problems of existing dish racks, such as limited folding methods, large size, and chaotic functional zoning, through the design of rotating sliding folding, bidirectional limiting structure, modular mesh frame components 30, and drainage system. It significantly improves the product's practicality, transportation economy, and user experience.

[0055] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
