Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present.

However, their use herein is for illustrative purposes only and is determined based on the exemplary orientations shown in the accompanying drawings, and does not represent the only possible implementation. Since the embodiments disclosed in this application can be arranged in different orientations, these terms indicating orientation are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that "axial arrangement" means that the overall arrangement direction is along the axial direction, including but not limited to axial extension, and may be at an angle to the axial direction.

[0039] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0040] like Figures 1-15 As shown, this application discloses a storage rack. The storage rack includes support members 1, a connecting assembly, a guide member, and a movable member. There are at least two support members 1, arranged at intervals relative to each other along a first direction X, which forms an angle with the length direction of the support member. The connecting assembly includes at least two connectors sequentially hinged along the first direction, with each end of the connecting assembly rotatably connected to a corresponding support member. The guide member is arranged side-by-side with the support members 1 at intervals, located between two support members 1, and rotatably connected to the connecting assembly. The movable member is arranged to engage with the guide member in a first position and a second position. In the first position, adjacent support members 1 are arranged close together, causing the storage rack to be in a folded state; in the second position, adjacent support members 1 are arranged far apart, causing the storage rack to be in an unfolded state.

[0041] Understandably, because the guide component and the connecting assembly are rotatably connected, and at least two support components are rotatably connected through the connecting assembly, the movable component and the guide component engage in a first position or a second position, allowing the shelf to be folded or unfolded, making the entire operation convenient. During transportation or storage, the shelf's volume can be reduced by folding, thus minimizing the space it occupies.

[0042] In this embodiment, the limiting member is provided with a stop part, and the guide member is provided with two locking parts 3 arranged at intervals along its own length direction. When the shelf is in the folded state, the stop part 41 can lock with one of the locking parts 3; when the shelf is in the unfolded state, the stop part 41 locks with the other locking part 3.

[0043] Thus, by locking the stop part 41 with the corresponding locking part 3, the stability of the shelf in the folded or unfolded state can be ensured.

[0044] The following embodiment uses guide rod 2 as the guide member, which is arranged vertically, and a kit 4 that is sleeved around guide rod 2 as the movable member. Specifically, kit 4 is sleeved around guide rod 2 and slides with guide rod 2.

[0045] Support member 1 is rotatably connected to kit 4 via connecting rod 5. Specifically, kit 4 is rotatably connected to connecting rod 5 on both sides arranged at intervals along the first direction X, and the ends of the two connecting rods 5 away from each other are rotatably connected to the support member 1 on the corresponding side.

[0046] In this embodiment, both the support member 1 and the guide rod are arranged vertically, and there are two support members 1. The guide rod 2 is located between the two support members 1 and is rotatably connected to the two support members 1 via a connector. Two locking parts 3 are arranged at intervals along the vertical direction of the guide rod 2. When the shelf is in the folded state, the stop part 41 locks with the lower locking part 3. When the shelf is in the unfolded state, the stop part 41 locks with the upper locking part 3.

[0047] Understandably, since kit 4 is slidably engaged with guide rod 2, and kit 4 is rotatably connected to the corresponding side support 1 via connecting rod 5, when guide rod 2 moves upward relative to kit 4 (i.e., kit 4 moves downward relative to guide rod 2), it will pull the two support 1 closer together. (See [reference]). Figure 14As shown. When the two support members 1 approach each other, the shelf will eventually fold together and lock with the lower locking part 3 through the stop part 41, thus fixing the shelf in the folded state. When it is necessary to unfold the shelf, simply release the lock between the stop part and the lower locking part 3, and press the guide rod 2 down. At this time, under the action of the connecting member, the guide rod 2 drives the two support members 1 to move away from each other until the shelf is in the unfolded state. In the unfolded state, the stop part 41 locks with the upper locking part 3, thus fixing the shelf in the unfolded state. The entire folding and unfolding process of the shelf is convenient and maintains the stability of the shelf in the folded or unfolded state.

[0048] In one embodiment, the aforementioned connector may be two connecting rods rotatably connected together via a first connecting shaft 72 (not shown in the figure). The ends of the two connecting rods furthest from each other are rotatably connected to the corresponding support member 1 via a second connecting rod. When the shelf is in the unfolded state, shelves of different heights are placed between the two support members 1.

[0049] In other embodiments, the connecting assembly may be a linkage assembly, and the connector may be a linkage. In this embodiment, such as Figures 1-11 As shown, the connecting component is the first shelf 7, and the connector is the shelf unit 71. The first shelf 7 includes at least two shelf units 71 arranged sequentially along the first direction X. Adjacent shelf units 71 are rotatably connected by a first connecting shaft 72. The first connecting shaft 72 is installed on the guide rod 2 and extends along the second direction Y. The second direction Y forms an angle with the first direction X and the length direction of the guide member. The support member is rotatably connected to the shelf unit 71 on the corresponding side through a second connecting shaft 73. Thus, the existence of the first shelf 7 facilitates the storage and placement of items, and it can also be folded to reduce the folded volume of the entire shelf.

[0050] In this embodiment, the first shelf 7 includes two shelf units 71, and each shelf unit 71 is rotatably connected to the corresponding side support member 1 via a second connecting shaft 73 on the side away from the other. In other embodiments (not shown), the first shelf 7 may also include three, four, or more shelf units 71.

[0051] In this embodiment, the first direction X is the left-right direction and the second direction Y is the front-back direction; or, the first direction X is the front-back direction and the second direction Y is the left-right direction.

[0052] Specifically, such as Figure 11As shown, connecting arms 711 are provided at the bottom of both the front and rear ends of the two shelf units 71. The connecting arms 711 of the two shelf units 71 on the front side are rotatably connected by a first connecting shaft 72, and the connecting arms 711 of the two shelf units 71 on the rear side are also rotatably connected by a first connecting shaft 72. The two first connecting shafts 72 are arranged coaxially. Alternatively, the two first connecting shafts 72 can be a single piece.

[0053] There are at least two first shelf panels 7, arranged at intervals along the vertical direction. Illustratively, there may be two, three, or more first shelf panels 7. In an embodiment, as... Figure 1 , Figure 3 and Figure 8 As shown, the ends of the two connecting rods 5 furthest from each other are rotatably connected to the first shelf 7 located in the middle via the second connecting shaft 73.

[0054] Furthermore, such as Figure 1 As shown, the aforementioned shelf also includes a second shelf 8 located above the first shelf 7, and the second shelf 8 rests on the support member 1. The presence of the second shelf 8 increases the space available for placing items.

[0055] The two support members 1 are defined as the first support member 11 and the second support member 12 respectively. The first side of the left and right sides of the second shelf plate 8 is rotatably connected to the first support member 11 through the mounting shaft 81. The mounting shaft 81 and the first connecting shaft 72 are arranged side by side at intervals. The second side of the left and right sides of the second shelf plate 8 rests on the second support member 12.

[0056] To increase the stability of the second shelf 8, the second support member 12 includes two support rods 13 spaced apart along the front-rear direction and a shelf rod 121 connecting the two support rods 13. The second side of the second shelf 8 is detachably mounted on the shelf rod 121 via a connecting structure 9. In this way, the stability of the shelf is increased when the second shelf 8 is in the unfolded state.

[0057] In this embodiment, the first support member 11 also includes two support rods 13 spaced apart along the front-rear direction. Along the left-right direction, the guide rod 2 is located between the two front support rods 13; or, between the two rear support rods 13. The second connecting shaft 73 is mounted on the corresponding support rod 13.

[0058] The bottom of the aforementioned support rod 13 is equipped with casters 131, which facilitates the movement of the shelf. Figure 15As shown, a roller 131 is provided at the bottom end of the support member 1, and at least a portion of the bottom end of the guide member is flush with the bottom end of the roller 131. In other embodiments, not shown in the figure, the bottom end of the support rod 13 may not be provided with the roller 131, in which case at least a portion of the bottom end of the guide member is flush with the bottom end of the support member 1.

[0059] Understandably, the bottom of the guide can rest on the ground or other surfaces to serve as a support, thus better supporting the shelf.

[0060] The aforementioned connection structure 9 can be a snap-fit ​​structure, a locking structure, or a screw or bolt connection.

[0061] In this embodiment, a locking structure is used as an example for explanation.

[0062] like Figure 1 As shown, the locking structure includes a limiting part 91 and a rotatable locking hook 92. The limiting part 91 is located on the rotation path of the hook portion of the locking hook 92. One of the locking hook 92 and the limiting part 91 is provided on the second side of the second shelf plate 8, and the other is provided on the side wall of the shelf rod 121. In this embodiment, the locking hook 92 is located on the side wall of the second side of the second shelf plate 8, and the limiting part 91 is located on the outer side wall of the shelf rod 121, and may be an outwardly protruding extension. The hook portion of the locking hook 92 can hook the limiting part 91, thereby realizing the connection between the second side of the second shelf plate 8 and the shelf rod 121.

[0063] In other embodiments (not shown in the figure), the stop part 41 is a plug-in part provided on the kit 4. The plug-in part is arranged to be able to move in and out of the kit 4. The locking part is a positioning hole opened on the side wall of the guide rod 2. When the shelf is in the unfolded or folded state, the plug-in part is plugged into the corresponding positioning hole.

[0064] In this embodiment, such as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the stop part 41 is a positioning hole opened on the inner side wall of the kit 4, and the locking part 3 includes a plug part 31 arranged to move inward and outward relative to the guide rod 2. When the shelf is in the unfolded or folded state, the positioning hole and the corresponding plug part 31 are plugged in and engaged.

[0065] The aforementioned kit 4 is fitted around the guide rod 2, and the guide rod 2 is located inside the kit 4. It should be noted that the inward and outward movement refers to the inward and outward movement along the horizontal direction (the direction that intersects with the vertical direction). For example, the inward and outward movement of the insertion part 31 refers to the movement along the horizontal direction towards or away from the positioning hole.

[0066] The following detailed description will be based on the example of a stop part 41 being a positioning hole and a locking part 3 including a plug-in part 31.

[0067] Furthermore, such as Figure 4 and Figure 9 As shown, the kit 4 is provided with an unlocking mechanism 6, which includes an unlocking member 61 that is movable inward and outward and constrained to the kit 4. The positioning hole is located on the movement path of the unlocking member 61. Since the insertion part 31 can be inserted into the positioning hole, by pushing the aforementioned unlocking member 61 inward, the insertion part 31 can be moved inward, that is, moved inward in a direction away from the positioning hole, thereby disengaging from the positioning hole.

[0068] The aforementioned kit 4 has an assembly cavity 40 formed at the position corresponding to the unlocking member 61. The assembly cavity 40 communicates with the positioning hole. A portion of the unlocking member 61 is located within the assembly cavity 40, and a sliding groove 611 and a sliding part 401 are fitted between the unlocking member 61 and the side wall of the assembly cavity 40 for sliding engagement. The groove 611 extends in the inward and outward direction. One of the groove 611 and the sliding part 401 is provided on the unlocking member 61, and the other is provided on the side wall of the assembly cavity. In this embodiment, the groove 611 is located on the outer side wall of the unlocking member 61, and the sliding part 401 is located within the assembly cavity 40.

[0069] Furthermore, the aforementioned unlocking mechanism 6 also includes a first elastic member 62 that ensures the unlocking member 61 always has an outward tendency to move. The first elastic member 62 abuts between the unlocking member 61 and the kit 4. Thus, when the force applied to the unlocking member 61 disappears, the unlocking member 61 moves outward under the action of the first elastic member 62, disengaging from the abutment of the insertion part 31, allowing the insertion part 31 to move outward.

[0070] The first elastic element 62 is a first spring or a leaf spring.

[0071] The guide rod 2 has a receiving cavity 20 at the position corresponding to the locking part 3 to accommodate the locking part 3. Schematic, the receiving cavity 20 can be a groove formed on the outer peripheral wall of the guide rod 2. The guide rod 2 can also be an I-shaped rod, in which case the receiving cavity 20 is the groove on the outer side of the I-shaped rod.

[0072] Alternatively, the guide rod 2 can also be in the form of a circular or square tube, and the receiving cavity 20 is a hollow cavity inside the guide rod 2. The following description assumes the guide rod 2 is in the form of a tube. In this case, the locking part 3 is located within the receiving cavity 20, and the side wall of the guide rod 2 has a through hole 21 at the position corresponding to the insertion part 31 for the insertion part 31 to pass through. The following three embodiments will specifically illustrate how the insertion part 31 moves in and out.

[0073] Example 1: As Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the locking part 3 includes an elastic plate 33 that is elastic and U-shaped or inverted U-shaped. The elastic plate 33 includes two vertical plates 331 arranged at intervals and a connecting plate 332 connecting the two vertical plates 331. The vertical plates 331 abut against the corresponding sidewalls of the guide rod 2. At least one vertical plate 331 has a plug-in part 31 on its outer plate surface. In other embodiments, only one vertical plate 331 has a plug-in part 31 on its outer plate surface. In this embodiment, both vertical plates 331 have plug-in parts 31 on their outer plate surfaces, and each plug-in part 31 corresponds to an unlocking mechanism 6. Thus, relying on the elasticity of the elastic plate 33 itself, the plug-in part 31 can be driven to move in and out.

[0074] Example 2: Figure 12 As shown, the locking part 3 includes a vertically arranged and elastic vertical plate 32. The vertical plate 32 is located inside the accommodating cavity 20, and the first end of the upper and lower ends of the vertical plate 32 is fixedly connected to the guide rod 2. The insertion part 31 is disposed on the outer wall surface of the second end of the upper and lower ends of the vertical plate 32. In this way, since the vertical plate 32 itself is elastic, it can drive the insertion part 31 to move in and out.

[0075] Each of the aforementioned locking parts 3 includes two vertical plates 32 arranged at relative intervals, and each vertical plate 32 is provided with a plug-in part 31. Thus, each locking part 3 corresponds to two unlocking parts 61 and two assembly cavities 40. In addition, there may be three or more vertical plates 32.

[0076] Example 3: Figure 13 As shown, the locking part 3 also includes a second elastic member 34 that ensures the insertion part 31 always has an outward movement tendency. The second elastic member 34 acts on the insertion part 31. The second elastic member 34 is located inside the receiving cavity 20 and presses against the guide rod 2 and the insertion part 31.

[0077] Furthermore, the locking part 3 also includes a limiting flange 311 that restricts the insertion part 31 from disengaging outward from the through hole 21. The limiting flange 311 is located inside the receiving cavity 20 and is disposed on the peripheral wall of the insertion part 31.

[0078] The guide rod 2 includes a vertical tube 22 and a support rod 23. A receiving cavity 20 is located inside the vertical tube 22, and the support rod 23 is located inside the receiving cavity 20 of the vertical tube 22 and is fixedly connected to the vertical tube 22. A second elastic member 34 presses against the support rod 23 and the insertion part 31. In one embodiment, the upper locking part 3 and the lower locking part 3 correspond to the same support rod 23.

[0079] In this embodiment, such as Figure 6 and Figure 13As shown, the upper positioning hole corresponds to a support rod 23, and the lower positioning hole also corresponds to a support rod 23. Specifically, the two locking parts 3 arranged sequentially from top to bottom are defined as upper locking part 301 and lower locking part 302, respectively. There are at least two stop parts 41, which are arranged circumferentially along the guide rod 2. Each stop part 41 corresponds to one upper locking part 301 and one lower locking part 302. All upper locking parts 301 correspond to one support rod 23, and this support rod 23 is defined as the first support rod. Each upper locking part 301 is located on the periphery of the first support rod. All lower locking parts 302 correspond to one support rod 23, and this support rod is defined as the second support rod. Each lower locking part 302 is located on the periphery of the second support rod.

[0080] The side wall of the aforementioned support rod is provided with a protrusion 231, and the second elastic element 34 is a second spring sleeved around the protrusion 231.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
