Description

Technical Field

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

[0002] Currently, storage racks are becoming increasingly important in people's lives as a convenient storage product that can organize and classify items. In order to further improve the ease of use of storage racks, storage racks that can switch between placing and storing items have also emerged.

[0003] However, in existing technologies, the switching between the storage and folding positions of a shelf is achieved by setting a pivot on the shelf. The pivot moves within a guide groove to switch the shelf between the two positions. This switching method has some problems: when the shelf is in the storage position, the pivot rotates within the guide groove, causing the shelf to sway to a certain extent. This results in instability during use, and the swaying generates noise and vibration, affecting the user experience.

[0004] Therefore, how to provide a storage rack that can prevent the shelf from swinging in the storage position has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this utility model is to provide a storage rack, comprising:

[0006] The base body is equipped with guide grooves and limiting structures.

[0008] Beneficial effects: This application uses a limiting structure to directly limit the rotation of the guide structure, solving the problem of shelf swaying at its source. It can effectively prevent or minimize shelf swaying; further reducing instability, noise and vibration caused by swaying, and improving the stability of the product in the storage state and the user experience; compared with the existing technology of directly limiting the shelf, this product has a better limiting effect, thus making the shelf more stable in the storage state.

[0009] Furthermore, the limiting structure includes a limiting groove; when the shelf is in the storage position, the limiting groove is used to limit the rotation of the guide structure, thereby limiting the movement of the shelf.

[0011] Furthermore, the shelf is also equipped with a movable component, which is movably disposed in a limiting groove. When the shelf moves from the placement position to the storage position, the guide structure moves in the guide groove, and the movable component moves in the limiting groove. When the shelf is in the storage position, the limiting groove can limit the movement of the movable component, thereby limiting the rotation of the guide structure.

[0012] Beneficial effects: By using movable parts that move within the limiting groove, the limiting groove restricts the movement of the movable parts. This allows for smoother switching between the shelf and the limiting position without affecting the movement of the guide structure within the guide groove.

[0013] Furthermore, the guide groove is connected to the limiting groove; during the process of the shelf moving from the placement position to the storage position, the guide structure moves from the guide groove to the limiting groove so that the limiting groove can limit the rotation of the guide structure.

[0018] Beneficial effects: When the guide structure moves within the V-shaped groove, it drives the shelf to switch between the placement position and the storage position. When it moves into the limiting groove, the limiting groove directly limits the guide structure. The limiting method is simple and the limiting effect is good. Furthermore, since the end wall of the limiting groove is a plane, the limiting plane formed is in contact with the matching plane on the guide structure to achieve mutual limiting. The structure is simple and the limiting effect is good.

[0019] Furthermore, the limiting groove is located on the inner circumference of the V-shaped groove; when the shelf is also equipped with a movable part, the movable part is movably disposed in the limiting groove; when the shelf moves from the placement position to the storage position, the guide structure moves in the guide groove, and the movable part moves in the limiting groove; when the shelf is in the storage position, the limiting groove can limit the movement of the movable part, so as to limit the rotation of the guide structure.

[0020] Beneficial effects: When the guide structure is at the second end of the V-groove, the limiting groove restricts the movement of the moving parts, preventing the guide structure from rotating, thereby preventing or greatly reducing the shaking of the shelf and improving product stability.

[0022] Beneficial effect: It can effectively switch between the storage rack and the organization rack.

[0023] Furthermore, the second groove is a straight groove or an arc groove; the first groove is a straight groove or an arc groove.

[0024] Furthermore, when the shelf is also equipped with a movable component, and the second groove is a straight groove, the limiting groove includes a strip groove; the limiting groove includes a strip groove, and the strip groove is parallel to the second groove; when the shelf moves from the placement position to the storage position, the guide structure moves in the guide groove, and at the same time the movable component moves in the limiting groove; when the shelf is in the storage position, the limiting groove can limit the movement of the movable component, so as to limit the rotation of the guide structure.

[0025] Beneficial effects: It ensures smoother movement of the guide structure within the V-groove, allowing the shelf to easily switch between the placement and storage positions.

[0026] Furthermore, when the first groove is an arc-shaped groove, the first end of the limiting groove corresponds to the V-top position, and the second end corresponds to the second end position of the V-shaped groove; the movable part rotates at the first end of the limiting groove, enabling the guide structure to move within the first groove; when the guide structure moves to the V-top position, the movable part can move from the first end of the limiting groove to the second end, and at the same time, the guide structure moves from the V-top position to the second end of the V-shaped groove, so that the shelf moves to the storage position.

[0030] Furthermore, the opening of the V-shaped groove faces downward or diagonally downward; when the shelf is also equipped with a movable part, when the guide structure is at the first end of the V-shaped groove and the movable part is at the first end of the limiting groove, the center of gravity of the movable part is lower than the center of gravity of the guide structure.

[0031] And / or, in the horizontal direction, relative to the first end of the limiting groove, the V-top of the V-groove is close to the second end of the V-groove.

[0032] Beneficial effects: The switching process is smoother and more effortless, improving ease of use.

[0033] Furthermore, the guide groove includes a rotating groove, and the guide structure is rotatably disposed within the rotating groove; and the rotation of the guide structure within the rotating groove enables the shelf to switch between the placement position and the storage position.

[0034] Beneficial effects: The guide structure rotates within the rotating slot, allowing the shelf to switch between the placement and storage positions, resulting in a simpler product structure.

[0038] Beneficial effect: It can prevent the guide structure from disengaging from the guide groove when the item is in the placement position, which would cause the shelf to detach from the base and drop the items on the shelf.

[0039] Furthermore, the limiting groove is connected to the rotating groove; the guide structure has a first position and a second position in the rotating groove, and the guide structure can enter the limiting groove when it is in the second position; during the process of the shelf moving from the placement position to the storage position, the guide structure rotates from the first position to the second position and then enters the limiting groove, so that the limiting groove can limit the rotation of the guide structure.

[0040] Beneficial effects: It can ensure that the shelf can be smoothly switched between the storage position and the folding position, and effectively limit the shelf when it is in the folding position.

[0041] Furthermore, the rotating groove has a circular cross-sectional shape, and a connecting port is provided on the side wall of the rotating groove. The limiting groove is connected to the rotating groove through the connecting port. The chord length of the connecting port is less than the diameter of the rotating groove. The dimensions of the guide structure in the first direction correspond to the dimensions of the connecting port, and the dimensions of the guide structure in the second direction correspond to the inner diameter of the rotating groove. When the guide structure is in the first position, the second direction of the guide structure is opposite to the connecting port, so that the guide structure is confined within the rotating groove. When the guide structure rotates to the second position, the first direction of the guide structure is opposite to the connecting port, so that the guide structure can enter the limiting groove.

[0042] Beneficial effect: It ensures that during the process of the shelf moving from the placement position to the storage position, the guide structure rotates from the first position to the second position and then enters the limiting groove, so that the limiting groove can limit the rotation of the guide structure.

[0045] Furthermore, the base is provided with a hollow cavity with a top connecting opening; the hollow cavity has a first inner wall and a second inner wall arranged opposite to each other, and the number of guide grooves is set to two, with the two guide grooves respectively set on the first inner wall and the second inner wall, and the shelf is set in the hollow cavity; the two ends of the shelf are respectively provided with guide structures, and the guide structures are set one-to-one with the guide grooves.

[0046] Beneficial effects: During the switching between the storage and retrieval positions, the guide structures at both ends of the shelf move within the corresponding guide grooves, ensuring the smoothness of the switching process.

[0048] Beneficial effect: By limiting the position of the shelf by the flange, the guide structure is prevented from disengaging from the guide groove, thus ensuring the reliability of the shelf when it is in the placement position.

[0049] Furthermore, a placement platform is provided on the side wall of the hollow cavity, and when the shelf is in the placement position, the shelf is placed on the placement platform; in the direction close to the U-shaped opening of the U-shaped structure, the guide groove and the placement platform are respectively provided at both ends of the hollow cavity.

[0076] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0077] The following is for reference. Figures 1-12 This invention describes a storage rack according to an embodiment of the present invention.

[0078] like Figures 1-12As shown, this application discloses a storage rack, including a base 1 and a shelf 2; the base 1 is provided with a guide groove 11 and a limiting structure; the shelf 2 is provided with a guide structure 21, which is movably disposed within the guide groove 11; the shelf 2 has a placement position and a storage position; when the guide structure 21 moves within the guide groove 11, it can drive the shelf 2 to switch between the placement position and the storage position; when the shelf 2 is in the storage position, the limiting structure can limit the rotation of the guide structure 21, thereby limiting the movement of the shelf 2. By employing a limiting structure to directly limit the rotation of the guide structure 21, the problem of the shelf 2 swaying is solved at its source. This effectively prevents or minimizes the swaying of the shelf 2, further reducing instability, noise, and vibration caused by swaying, and improving the stability of the product and the user experience when stored. Compared to existing technologies that directly limit the shelf 2, this product has a better limiting effect, resulting in better stability of the shelf 2 when stored. Here, the rotation of the guide structure 21 refers to the rotation of the guide structure 21 around its own center of rotation. For example, if the guide structure 21 is a cylindrical structure, its rotation around its own central axis constitutes rotation. Figure 2 The middle section is the storage area. Figure 3 The center is the storage area. This application's shelf can hold daily necessities, fruits, vegetables, eggs, water cups, or jewelry, etc. When placing easily rolling items such as eggs or fruits on the shelf 2, grooves, holes, or retaining rings can be provided on the shelf 2 to place these items within the grooves, holes, or retaining rings to prevent them from rolling.

[0079] In the prior art, the shelf 2 is equipped with a guide structure 21, and the shelf 2 can swing around the guide structure 21 as the rotation center, similar to a seesaw structure. The usual way to prevent the shelf 2 from swinging is to directly limit the shelf 2 on one or both sides of the pivot. This can prevent the shelf 2 from rotating to a certain extent, but this limiting method is not very effective in limiting the shelf 2. It cannot solve the problem of the shelf 2 swinging. It can only prevent the shelf 2 from flipping over. Moreover, when the shelf 2 swings, it will hit the base 1, causing the whole product to vibrate and affecting its use. For example, when liquids such as water cups or oil cups are placed on the shelf 2, the swinging of one shelf 2 will hit the other shelves 2 or the base 1 and cause the liquid to fluctuate or even spill.

[0080] Compared to the existing technology where the limiting structure directly limits the shelf 2, this application limits the rotation of the guide structure 21 through the limiting structure, which fundamentally solves the swaying problem of the shelf 2, has a good limiting effect, and greatly improves the stability of the shelf 2.

[0081] When the shelf 2 is in the storage position, the limiting structure can limit the rotation of the guide structure 21, thereby limiting the movement of the shelf 2; in fact, the limiting structure restricts the rotation of the guide structure 21, thereby limiting the swing of the shelf 2 with the guide structure 21 as the base point.

[0082] In some embodiments, the limiting structure includes a limiting buckle, such as an elastic buckle. When the shelf 2 is in the storage position, the guide structure 21 moves to the corresponding position of the limiting structure and is limited by the limiting buckle, which can prevent the guide structure 21 from rotating in the guide groove 11 and effectively prevent the shelf 2 from swinging in the storage state. When it is necessary to switch the shelf 2 from the storage position to the storage position, the user holds and pushes the shelf 2 to overcome the limiting effect of the elastic buckle, causing the elastic buckle to deform. At this time, the guide structure 21 is released from the limiting effect of the limiting buckle and moves in the guide groove 11.

[0083] In some embodiments, the limiting structure includes a first concave-convex structure, and the guide structure 21 is provided with a second concave-convex structure. At least one of the first and second concave-convex structures is elastic or retractable. When the guide structure 21 moves to the limiting structure position, the first and second concave-convex structures engage in a concave-convex fit, thereby preventing the guide structure 21 from rotating within the guide groove 11. When it is necessary to switch the shelf 2 from the storage position to the placement position, the user pushes the shelf 2, and at least one of the first and second concave-convex structures undergoes elastic deformation, causing the guide structure 21 to disengage from the limiting effect and move within the guide groove 11. One of the first and second concave-convex structures is a groove, and the other is a protrusion; the inner wall of the groove can undergo elastic deformation, or the protrusion can undergo elastic deformation; or the protrusion is retractably provided on the inner wall of the guide groove 11 on the guide structure 21.

[0084] In some embodiments, the shelf 2 is parallel to or inclined to the horizontal plane when in the placement position; when in the storage position, the shelf 2 is parallel to the vertical direction or at a slight angle, such as 30 degrees to the vertical direction. In use, the shelf 2 is parallel to or inclined to the horizontal plane, allowing items to be placed. When not in use, the shelf 2 can be flipped to the vertical position to save space. In this embodiment, the shelf 2 can be used to place fruits, vegetables, eggs, etc.

[0085] In some embodiments, the shelf 2 is parallel to or inclined to the vertical direction when in the storage position; the shelf 2 is horizontal when in the storage position; that is, the shelf 2 is used for storing items when in the vertical direction, such as multiple hooks on the shelf for hanging spoons, peelers, pot brushes, etc.; or jewelry such as necklaces, bracelets, etc. can be hung on the hooks.

[0086] This application also discloses some embodiments, in which the limiting structure includes a limiting groove 12; when the shelf 2 is in the storage position, the limiting groove 12 is used to limit the rotation of the guide structure 21, thereby limiting the movement of the shelf 2. Using the limiting groove 12 for limiting is simple to set, has low production and manufacturing costs, and the limiting effect of the limiting groove 12 is good.

[0087] This application also discloses some embodiments in which a movable member 22 is provided on the shelf 2, and the movable member 22 is movably disposed in the limiting groove 12. When the shelf 2 moves from the placement position to the storage position, the guide structure 21 moves in the guide groove 11, and the movable member 22 moves in the limiting groove 12. When the shelf 2 is in the storage position, the limiting groove 12 can limit the movement of the movable member 22, thereby limiting the rotation of the guide structure 21. By using the movable member 22 to move in the limiting groove 12, when the shelf 2 is in the storage position, the limiting groove 12 can limit the movement of the movable member 22. At this time, by limiting the movement of the movable member 22, the rotation of the guide structure 21 in the guide groove 11 is limited. That is, the limiting groove 12 can prevent the movable member 22 from moving in a certain direction. At this time, the guide structure 21 cannot rotate in the guide groove 11, thereby preventing the shelf 2 from swinging.

[0088] This application also discloses some embodiments in which the guide groove 11 is connected to the limiting groove 12. During the movement of the shelf 2 from the placement position to the storage position, the guide structure 21 moves from the guide groove 11 into the limiting groove 12, so that the limiting groove 12 can limit the rotation of the guide structure 21. The connection between the guide groove 11 and the limiting groove 12 allows the guide structure 21 to be limited when it moves into the limiting groove 12. This is convenient to use, requiring no additional operation to limit the rotation of the guide structure 21, resulting in simple operation and good limiting effect.

[0089] This application also discloses some embodiments, in which the guide groove 11 includes a V-shaped groove 111, and the guide structure 21 moves within the V-shaped groove 111 to allow the shelf 2 to switch between a placement position and a storage position; when the guide structure 21 moves to the first end of the V-shaped groove 111, the shelf 2 is in the placement position; when the guide structure 21 moves to the second end of the V-shaped groove 111, the shelf 2 is in the storage position, and the limiting structure can limit the rotation of the guide structure 21. This application uses a V-shaped groove 111 because its shape allows the shelf 2 to switch directly between the placement and storage positions, resulting in a simple structure, convenient switching, and ease of production and manufacturing. In this application, the two sides of the V-shape of the V-groove 111 can be any shape, such as straight, curved, or wavy, and the overall guide of the guide groove 11 can be V-shaped; the two sides can be of the same length or different lengths. The V-groove 111 has two side walls and two end walls that are arranged opposite to each other. The two side walls extend in the extending direction of the V-groove 111, and the two end walls are located at the two ends of the V-groove 111 respectively and connect the two side walls of the V-groove 111.

[0090] In some embodiments, the guide structure 21 is a slider that slides within the V-groove 111, moving from one end of the V-groove 111 to the other, allowing the shelf 2 to switch between a placement position and a storage position. This sliding motion is more stable and smoother, making the switching of the shelf 2 more seamless; furthermore, the slider is easy to produce and manufacture, and is inexpensive.

[0091] In some embodiments, the guide structure 21 is a slider, the outer peripheral wall of which is formed by a first contact plane, a first surface, a second contact plane, and a second surface joined end to end to enclose it; the first contact surface and the second contact surface are arranged opposite to each other; throughout the entire movement of the slider within the V-groove 111, the two opposite contact planes on the slider are always in contact with the two opposite sidewalls of the V-groove 111 and slide in contact; the second surface and the third surface are arranged opposite to each other, and throughout the entire movement of the slider, the second surface always faces the first end of the V-groove, and the third surface always faces the second end of the V-groove; when the guide structure 21 moves to the second end of the V-groove 111, the third surface is in contact with the end wall of the second end of the V-groove 111. The third surface can be a plane, in which case the end wall of the second end of the V-groove 111 is a plane; the third surface can be a protruding arc-shaped surface, in which case the V-groove 111 is an arc-shaped surface adapted to the third surface. In this embodiment, since the first and second planes are always in contact with the two sidewalls of the V-groove 111, the two sidewalls form circumferential limits on the first and second planes, preventing the slider from rotating. This restricts the swing of the shelf 2 with the slider as the base point, ensuring the stability of the product and the user experience. When both the second and third surfaces are planes, the slider is a cuboid or cube; production and manufacturing are more convenient.

[0092] Furthermore, the second surface is an arc-shaped surface, and the first end wall of the V-groove 111 is an arc-shaped surface adapted to the second surface. Alternatively, the guide structure 21 is a cylindrical structure, and both the first and second end walls of the V-groove 111 are arc-shaped surfaces adapted to the arc surface of the cylindrical structure; the first end wall of the guide groove 11 is also an arc-shaped surface. The center of the arc surface of the first end wall of the guide groove 11 is lower than the center of the first end wall of the V-groove 111; this facilitates the upward sliding of the guide structure 21 and makes upward flipping easier, preventing problems such as inability to flip or uneven reversal during use.

[0093] This application also discloses some embodiments in which a limiting groove 12 is disposed at the second end of a V-shaped groove 111 and communicates with the V-shaped groove 111; the end of the limiting groove 12 has a limiting plane, and the guide structure 21 is provided with an adapter plane corresponding to the limiting plane; when the shelf 2 moves from the placement position to the storage position, the guide structure 21 moves from the guide groove 11 into the limiting groove 12, and the adapter plane fits with the limiting plane, so that the limiting groove 12 can limit the rotation of the guide structure 21. When the guide structure 21 moves in the V-shaped groove 111, it drives the shelf 2 to switch between the placement position and the storage position. When it moves into the limiting groove 12, the limiting groove 12 directly limits the guide structure 21. The limiting method is simple and the limiting effect is good; and because the end wall of the limiting groove 12 is a plane, the limiting plane formed and the adapter plane on the guide structure 21 fit together to achieve mutual limiting. The structure is simple and the limiting effect is good. In this embodiment, the end wall of the limiting groove 12 is a limiting plane; when the shelf 2 is in the storage position, the fitting plane is in contact with the limiting plane, and there is an angle between the limiting plane and the side wall of the V-shaped groove 111. At this time, there is also an angle between the fitting plane and the side wall of the V-shaped groove 111. At this time, the side wall of the V-shaped groove 111 limits the rotation of the guide structure 21, and the limiting effect is good.

[0094] In some embodiments, the slider has a D-shaped cross-section, with the flat portion of the D-shape facing the second end of the V-groove 111 and corresponding to the end face size of the V-groove 111. When the guide structure 21 moves to the second end, the flat portion fits against the end wall of the second end, and the size is just enough to allow the guide structure 21 to be placed in the V-groove 111, preventing it from rotating. This effectively limits the rotation of the slider, thereby preventing or reducing the swaying of the shelf 2 and solving the stability and noise problems caused by the swaying of the shelf 2.

[0095] This application also discloses some embodiments in which the limiting groove 12 is located on the inner circumferential side of the V-shaped groove 111; when the shelf 2 is also provided with a movable part 22, the movable part 22 is movably disposed in the limiting groove 12; when the shelf 2 moves from the placement position to the storage position, the guide structure 21 moves in the guide groove 11, and the movable part 22 moves in the limiting groove 12; when the shelf 2 is in the storage position, the limiting groove 12 can limit the movement of the movable part 22, thereby limiting the rotation of the guide structure 21. When the guide structure 21 is at the second end of the V-shaped groove 111, since the limiting groove 12 limits the movement of the movable part 22 at this time, the guide structure 21 cannot rotate, thereby preventing or greatly reducing the shaking of the shelf 2 and improving the product stability.

[0096] This application also discloses some embodiments, wherein the V-shaped groove 111 includes a first groove 1111 and a second groove 1112 that are interconnected, and the connection position of the first groove 1111 and the second groove 1112 forms the V-top of the V-shaped groove 111; the V-shaped opening of the V-shaped groove 111 is arranged facing downward or obliquely downward; the first end of the V-shaped groove 111 is located in the first groove 1111, and the second end of the V-shaped groove 111 is located in the second groove 1112. This allows the shelf 2 to be effectively switched between a placement position and a storage position.

[0097] This application also discloses some embodiments, wherein the second groove 1112 is a straight groove or an arc groove; and the first groove 1111 is a straight groove or an arc groove.

[0098] This application also discloses some embodiments. When the shelf 2 is further provided with a movable part 22, and the second groove 1112 is a straight groove, the limiting groove 12 includes a strip groove; the limiting groove 12 includes a strip groove, and the strip groove is parallel to the second groove 1112; when the shelf 2 moves from the placement position to the storage position, the guide structure 21 moves in the guide groove 11, and at the same time, the movable part 22 moves in the limiting groove 12; when the shelf 2 is in the storage position, the limiting groove 12 can limit the movement of the movable part 22, thereby limiting the rotation of the guide structure 21. This ensures that the movement of the guide structure 21 in the V-shaped groove 111 is smoother, so that the shelf 2 can smoothly switch between the placement position and the storage position.

[0099] This application also discloses some embodiments in which, when the first groove 1111 is an arc-shaped groove, the first end of the limiting groove 12 corresponds to the V-top position, and the second end corresponds to the second end position of the V-shaped groove 111; the movable member 22 rotates at the first end of the limiting groove 12, enabling the guide structure 21 to move within the first groove 1111; when the guide structure 21 moves to the V-top position, the movable member 22 can move from the first end of the limiting groove 12 to the second end, and simultaneously, the guide structure 21 moves from the V-top position to the second end of the V-shaped groove 111, so that the shelf 2 moves to the storage position. Using this method, the setting of the limiting groove 12 is simple and easy to manufacture.

[0100] This application also discloses some embodiments where, when the second groove 1112 is an arc-shaped groove, the first groove 1111 is an arc-shaped groove, and the shelf 2 is also provided with a movable part 22, the centers of the first groove 1111 and the second groove 1112 are the same; the limiting groove 12 is located at the center position; during the process of the shelf 2 moving from the placement position to the storage position, the movable part 22 rotates within the limiting groove 12. The rotation trajectory of the guide structure 21 is an arc-shaped trajectory. During the entire switching process of the shelf 2, the movement of the guide structure is smoother, and the user does not experience any jerking during the switching process, which is more in line with the user's usage habits.

[0101] In some embodiments, the guide groove 11 is a V-shaped groove 111, the first groove 1111 and the second groove 1112 are both arc segments, the first groove 1111 and the second groove 1112 are interconnected and their centers coincide, the cross-section of the limiting groove 12 is circular, the movable member 22 is a rotating shaft, the cross-sectional dimensions of the rotating shaft correspond to the cross-sectional dimensions of the limiting groove 12, for example, the outer peripheral wall of the rotating shaft and the inner peripheral wall of the limiting groove 12 are clearance fit, so that the rotating shaft can rotate in the limiting groove 12, and the rotating shaft cannot move in other directions, or can move in other directions within a small range; at this time, when the rotating shaft rotates, it moves within the arc segment of the first groove 1111 and the second groove 1112, that is, with the central axis of the rotating shaft as the center, the distance between the guide structure 21 and the central axis of the rotating shaft as the radius, and the rotation path of the guide structure 21, that is, the arc segment formed by the first groove 1111 and the second groove 1112, is one end arc on the circle. In this method, when the user needs to flip the shelf 2 from the storage position to the folding position, no extra operation is required; simply push the shelf 2 upwards. At this time, the movable part 22 rotates within the limiting groove 12 about its own central axis. When the guide structure 21 moves to the end of the second groove 1112, i.e., the second end of the V-shaped groove 111, the limiting structure cannot rotate because the movable part 22, i.e., the pivot, can only rotate within the limiting groove 12. This is because if the limiting structure were to rotate, the central axis of the movable part 22 and the limiting structure would form a radius, requiring the movable part 22 to have an arc-shaped path. However, since the movable part 22 can only rotate within the limiting groove 12... The circular cross-section of the limiting groove 12 restricts the movement of the movable part 22 on the arc path, thus preventing the movable part 22 from moving on the arc path. This limits the rotation of the limiting structure and prevents the shelf 2 from swaying. The swaying problem of the shelf 2 is solved from the source. When the shelf 2 is in the storage position, since the limiting structure cannot rotate at the second end of the V-shaped groove 111, the shelf 2 will not sway around the limiting structure as the base point, ensuring its stability in the storage position. Therefore, it cannot sway during use or transportation, which would cause instability, and there will be no noise or vibration caused by swaying, greatly improving the user experience.

[0102] This application also discloses some embodiments, in which the limiting groove 12 is also a V-shaped groove 111, and the limiting groove 12 is arranged parallel to the guide groove 11; the guide structure 21 and the movable part 22 are both sliding structures. When the guide structure 21 slides in the limiting groove 12, the movable part 22 slides in the limiting groove 12. When the guide structure 21 moves to the second end of the V-shaped groove 111, the movable part 22 also moves to the corresponding end of the limiting groove 12. At this time, the limiting groove 12 can limit the movement of the movable part 22, so the guide structure 21 cannot rotate in the guide groove 11, thereby solving the problem of the swaying of the shelf 2 with the guide structure 21 as the base point, and thus solving the problem of the stability and noise caused by the swaying of the shelf 2.

[0103] This application also discloses some embodiments in which the first groove 1111 and the second groove 1112 are both straight grooves. The guide structure 21 slides in the V-shaped groove 111 to drive the shelf 2 to switch between the placement position and the storage position. The straight groove is more convenient to produce and manufacture and has higher production efficiency.

[0104] This application also discloses some embodiments, wherein the first groove 1111 is an arc-shaped groove and the second groove 1112 is a straight groove; when the guide structure 21 slides in the first groove 1111, the movable member 22 rotates at the first end of the limiting groove 12. At this time, with the central axis of the movable member 22 as the center of rotation, the arc-shaped groove forms the movement path of the guide structure 21; when the guide structure 21 moves to the top of V, that is, the connection position of the first groove 1111 and the second side, the movable member 22 slides synchronously with the guide structure 21, the movable member 22 slides to the second end of the limiting groove 12, and the guide structure 21 slides to the second end of the second groove 1112. Since the movement of the front part of the guide structure 21 is a rotational movement with the movable member 22 as the center when flipping the shelf 2, the user's hand feel is smoother and there is no sense of jerking. Rotating to the corresponding position and then moving downwards is simple and conforms to the user's usage habits. Figure 10-12 As shown, the working principle of this embodiment is as follows: the shelf 2 is in the placement position (e.g., Figure 2 When in position), the positions of guide structure 21 and moving part 22 are as follows: Figure 10 As shown; when the shelf 2 is in its self-positioning location (e.g. Figure 2 Location) Move to storage location (e.g.) Figure 3 When in position, the movable part 22 rotates at the first end of the limiting groove 12, and the guide structure 21 moves within the arc-shaped groove until it reaches the desired position. Figure 11 The position shown in the figure; at this time, the guide structure 21 and the movable part 22 move simultaneously to the position shown in the figure. Figure 12 As shown in the image, shelf 2 can be moved to the storage position (e.g., Figure 3 Location).

[0105] This application also discloses some embodiments in which the opening of the V-shaped groove 111 faces downward or diagonally downward; when the shelf 2 is also provided with a movable part 22, when the guide structure 21 is at the first end of the V-shaped groove 111 and the movable part 22 is at the first end of the limiting groove 12, the center of gravity of the movable part 22 is lower than the center of gravity of the guide structure 21; during the switching process, it is smoother and more effortless, and the convenience of use is improved.

[0106] And / or, in the horizontal direction, relative to the first end of the limiting groove 12, the V-top of the V-groove 111 is close to the second end of the V-groove 111.

[0107] This application also discloses some embodiments, in which the guide groove 11 includes a rotating groove 112, and the guide structure 21 is rotatably disposed within the rotating groove 112; and the rotation of the guide structure 21 within the rotating groove 112 can drive the shelf 2 to switch between the placement position and the storage position. By rotating the guide structure 21 within the rotating groove 112, the shelf 2 can be driven to switch between the placement position and the storage position, resulting in a simpler product structure.

[0108] This application also discloses some embodiments in which the guide groove 11 includes a rotating groove 112, and a notch 1121 is provided on the inner wall of the rotating groove 112. The guide structure 21 can be installed in the rotating groove 112 through the notch 1121. This facilitates the installation and disassembly of the guide structure 21, and thus facilitates the maintenance and replacement of the shelf 2.

[0109] This application also discloses some embodiments in which a limiting member is provided on the base 1; when the shelf 2 is in the placement position, the limiting member is used to limit the movement of the guide structure 21 in the direction of extending out of the notch 1121. This can prevent the guide structure 21 from disengaging from the guide groove 11 when in the placement position, which would cause the shelf 2 to detach from the base 1 and drop the items on the shelf 2.

[0110] This application also discloses some embodiments in which the limiting groove 12 is connected to the rotating groove 112; the guide structure 21 has a first position and a second position in the rotating groove 112, and the guide structure 21 can enter the limiting groove 12 when in the second position; during the process of the shelf 2 moving from the placement position to the storage position, the guide structure 21 rotates from the first position to the second position and then enters the limiting groove 12, so that the limiting groove 12 can limit the rotation of the guide structure 21. This can ensure that the shelf 2 switches smoothly between the placement position and the storage position, and effectively limit the shelf 2 when in the storage position.

[0111] This application also discloses some embodiments in which the rotating groove 112 has a circular cross-sectional shape and a connecting port 1122 is provided on the side wall of the rotating groove 112. The limiting groove 12 is connected to the rotating groove 112 through the connecting port 1122. The chord length of the connecting port 1122 is less than the diameter of the rotating groove 112. The size of the guide structure 21 in the first direction corresponds to the size of the connecting port 1122, and the size of the guide structure 21 in the second direction corresponds to the inner diameter of the rotating groove 112. When the guide structure 21 is in the first position, the second direction of the guide structure 21 is opposite to the connecting port 1122, so that the guide structure 21 is limited to the rotating groove 112. When the guide structure 21 is rotated to the second position, the first direction of the guide structure 21 is opposite to the connecting port 1122, so that the guide structure 21 can enter the limiting groove 12. This ensures that during the process of the shelf 2 moving from the placement position to the storage position, the guide structure 21 can rotate from the first position to the second position and then enter the limiting groove 12, so that the limiting groove 12 can limit the rotation of the guide structure 21.

[0112] This application also discloses some embodiments. The outer peripheral wall of the guide structure 21 includes a first plane, a first arc surface, a second plane, and a second arc surface that are connected end to end. The first plane and the second plane are arranged opposite to each other. When the guide structure 21 rotates within the rotating groove 112, the first arc surface and the second arc surface are in contact with the inner peripheral wall of the rotating groove 112. The limiting groove 12 has a first side wall and a second side wall that are arranged opposite to each other. When the guide structure 21 is located within the limiting groove 12, the first plane and the second plane are in contact with the first side wall and the second side wall, respectively. The two arc surfaces ensure that the guide structure 21 can rotate within the rotating groove 112, while the two planes allow the guide structure 21 to be limited within the limiting groove 12. The structure is simple and the effect is good.

[0113] The activity process of this embodiment is combined with the appendix Figure 6-9 It can be seen that shelf 2 is located in the storage position (such as...) Figure 2 When the position is as follows, the position of the guide structure 21 is as follows: Figure 6 As shown, when it is necessary to move the shelf 2 to its designated position (e.g., Figure 2 Location) Move to storage location (e.g.) Figure 3 When in position), the guide structure 21 rotates to Figure 7 In the middle position, move to Figure 8 The position is within the limiting groove 12, at which point the limiting groove 12 can limit the rotation of the guide structure 21, preventing the guide structure 21 from rotating; in the position where the shelf 2 needs to be self-folded (e.g. Figure 3 (Location) Move to the storage location (e.g.) Figure 2 When in position), the guide structure 21 self- Figure 8 Move upwards from the middle position. Figure 7 The position is within the rotating slot 112, then rotate to... Figure 6 Location.

[0114] This application also discloses some embodiments, in which a hollow cavity 13 with a top connecting port 1122 is provided on the base 1; the hollow cavity 13 has a first inner wall 131 and a second inner wall 132 arranged opposite to each other, and two guide grooves 11 are provided, which are respectively provided on the first inner wall 131 and the second inner wall 132; the shelf 2 is disposed in the hollow cavity 13; guide structures 21 are provided at both ends of the shelf 2, and the guide structures 21 are correspondingly provided with the guide grooves 11.

[0115] This application also discloses some embodiments, in which the hollow cavity 13 has a third inner wall 133; the first inner wall 131, the third inner wall 133, and the second inner wall 132 are sequentially connected to form a U-shaped structure; when a limiting member is provided on the seat 1, an inwardly folded flange 134 is provided at the opening of the U-shaped structure, and the flange 134 forms a limiting member. By limiting the shelf 2 with the flange 134, the guide structure 21 is prevented from disengaging from the guide groove 11, thus ensuring the reliability of the shelf 2 in the placement position.

[0116] This application also discloses some embodiments in which a placement platform 135 is provided on the side wall of the hollow cavity 13. When the shelf 2 is in the placement position, the shelf 2 is placed on the placement platform 135. In the direction close to the U-shaped opening of the U-shaped structure, the guide groove 11 and the placement platform 135 are respectively provided at both ends of the hollow cavity 13. This gives the shelf 2 four support positions, two placement platforms 135, and two guide grooves 11, making the shelf 2 more stable in the placement position, less prone to tipping over, and improving the stability of the product in use.

[0119] This application also discloses some embodiments in which the fixing frame 3 is set at the bottom of the shelf 2; the fixing frame 3 is set at the bottom of the shelf 2 to form the bottom of the base 1, so that the center of gravity of the shelf 2 is lower, making it more stable and the overall structure is not easy to tip over; and in the process of use, the eggs on the shelf 2 above the fixing frame 3 are used first. After all the eggs on the shelf 2 are used up, the shelf 2 is flipped to the storage position. At this time, there are still items such as eggs on the fixing frame 3. Since they are heavier, the center of gravity of the whole structure is lowered, and it will not tip over due to being top-heavy, thus making it more stable.
