Description

Technical Field

[0001] The utility model relates to the field of automatic vending machines, in particular to a rotary shelf and an automatic vending machine with the rotary shelf. Background Art

[0002] Common vending machine shelves include spiral shelves, crawler shelves, shelf shelves, lifting shelves, drawer shelves, etc. In recent years, some vending machines that sell industrial products have begun to use rotary shelves. When the user purchases a specified product, the rotary shelf can rotate the storage compartment carrying the specified product to the cabinet door, and the user can open the cabinet door to take the product away.

[0003] The rotating shelves generally adopt a multi-layer design. In order to form radially distributed storage compartments, each layer needs to be separated by multiple column partitions, so the number of layer partitions and column partitions is large. Furthermore, in the rotating shelves of the prior art, in order to fix the multiple layer partitions and column partitions to each other, and in order to fix the layer partitions and column partitions to the middle tube of the rotating shelves, a large number of fasteners such as threaded connectors are required, and the assembly process is complicated, which is not conducive to large-scale production. Summary of the invention

[0004] In view of the above problems, the utility model provides a rotary shelf and a vending machine with the rotary shelf, which can reduce the use of fasteners and simplify the assembly process.

[0005] The first aspect of the utility model provides a rotating shelf, comprising a middle cylinder, a plurality of layer partitions, a plurality of column partitions and a hoop, wherein the middle cylinder has a cylindrical cylinder wall, and a plurality of first through holes are opened on the cylinder wall; the layer partition is annular, and the plate surfaces of the plurality of layer partitions are parallel to each other and perpendicular to the axial direction of the middle cylinder, and the plurality of layer partitions are spaced apart in the axial direction of the middle cylinder, and a plurality of first slots are arranged on the radial outer edge of the layer partition; the plurality of column partitions extend radially outward along the cylinder surface of the middle cylinder and are radially distributed, and a plurality of second slots are arranged on the inner edge of the column partition, the inner periphery of the layer partition is embedded in the second slots, and the outer edge of the column partition is embedded in the first slots, and a protrusion is arranged on the inner edge of the column partition, and the inner edge of the column partition abuts the cylinder wall, and the protrusion is inserted into the first through hole, and the plurality of column partitions are also provided with second through holes at positions corresponding to each other; the hoop clamps the plurality of column partitions together by passing through the second through holes of the plurality of column partitions.

[0006] According to the above technical solution, it is only necessary to install multiple layer partitions at intervals on the middle tube, and then insert multiple column partitions into the first slots on the radial outer edge of the layer partitions. The layer partitions and column partitions can be interlocked by using the first slots and the second slots. Moreover, because of the mutual insertion, the extension ranges of the layer partitions and column partitions in the radial direction can overlap with each other, which can play a role in supporting each other stably. After the middle tube, layer partitions and column partitions are pre-assembled, the hoop can be used to hoop all the column partitions to tighten them, thereby improving the overall fixing tightness of the shelf and making the structure more compact and stable.

[0007] Optionally, a second through hole is provided between each two layer partitions of the column partition, and there are a plurality of hoop rings, each of which passes through the second through holes corresponding to each other in the axial position. The column partitions of the same layer can be hooped and tightened at each layer by using a plurality of hoop rings, and a force is uniformly applied in the axial direction of the entire middle tube to tighten the plurality of column partitions. The tightened hoop ring can not only combine the column partitions, but also apply a radially inward force to the column partitions, and the radially inward force can also make the fixation between the column partition and the middle tube tighter, and ensure the consistency of the structure and size of the assembled product.

[0008] Optionally, the second through hole is arranged at the inner edge of the column partition and adjacent to the protrusion. The second through hole is arranged adjacent to the protrusion, which can effectively ensure that the radially inward force applied by the hoop to the column partition can be effectively transmitted to between the protrusion and the middle tube, thereby ensuring the tightness of the connection between the protrusion and the middle tube. Moreover, arranging the second through hole at this position can also shorten the required length of the hoop and reduce costs.

[0009] Optionally, a grid plate is further included, which is detachably connected to the middle tube, the column partition plate and / or the layer partition plate, and further divides the storage compartment separated by the layer partition plate and the column partition plate into two or more sub-grid openings. The size of the sub-grid openings can be adjusted by the grid plate. When a large storage compartment is needed, the grid plate can be discarded. When a small storage compartment is needed, the grid plate can be used to divide the storage compartment, so that it can be flexibly adjusted according to the size of the goods to be placed, and more categories of goods can be adapted, and the space utilization efficiency can be improved.

[0010] Optionally, the grid plate is arranged along the radial plane of the middle tube, and the grid plate has a first end and a second end opposite to each other along the axial direction of the middle tube, the first end of the grid plate has a grid plate protrusion, the grid plate protrusion is inserted into the slot of the layer partition, and the second end of the grid plate has a threaded connection portion, and the grid plate is threadedly connected to the layer partition located on the other side of the grid plate by the threaded connection portion. According to the above technical solution, the grid plate can be stably fixed between the upper and lower layer partitions, and the installer of the vending machine can choose whether to use the grid plate according to needs, and even when the grid plate is not used, the surface of the layer partition is relatively flat and smooth, which is convenient for goods to enter and exit the storage compartment.

[0011] Optionally, the inner edge of the grid plate has a grid plate avoidance opening for avoiding the hoop. By providing the grid plate avoidance opening on the inner edge of the grid plate, on the one hand, the inner edge of the grid plate can still be fixedly connected to the middle tube to ensure the stability of the grid plate fixation; on the other hand, by avoiding the hoop, the installation of the grid plate will not affect the main structure of the assembled rotating shelf, and the grid plate can be added as needed after the rotating shelf has been assembled as a whole.

[0012] Optionally, the wall of the middle cylinder is further provided with a third through hole, and the inner edge of the grid plate is further provided with a grid plate inner edge protrusion, which is inserted into the third through hole of the middle cylinder. According to the above technical solution, the inner edge protrusion, the grid plate protrusion and the threaded connection part can limit or fix the grid plate from three different directions, thereby improving the stability of fixing the grid plate.

[0013] Optionally, the width of the first slot and / or the second slot is 1.5-2mm. The width of the first slot and the second slot should not be too wide or too narrow. First, the width should be suitable for the layer partitions or column partitions to be inserted and interlocked with each other. The layer partitions and column partitions need to ensure a certain strength or thickness, so the width of the first slot and the second slot should not be too narrow; on the other hand, the thickness of the layer partitions and column partitions should not be too thick. Too thick layer partitions and column partitions will cause a significant increase in the weight of the rotating shelf. Therefore, based on the above two points, combined with the thickness of the layer partitions and column partitions, the width of the first slot and the second slot is preferably in the range of 1.5-2mm.

[0014] Optionally, the outer end of the first slot also has a flared portion with a width greater than that of the first slot. The flared portion can facilitate the insertion of the first slot and the column partition plate, and guide the column partition plate to enter the first slot.

[0015] The second aspect of the utility model provides an automatic vending machine having the rotary shelf provided by the first aspect of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] <Term>

[0028] The terms “perpendicular” and “parallel” do not require a strict 90° angle in a geometric sense, but may be substantially perpendicular or substantially parallel, for example, with a tolerance range of within 15°.

[0029] The term "adjacent" when describing the positional relationship between the second through hole and the protrusion means that the force applied by the hoop to the second through hole can be basically transmitted to the protrusion to enhance the tightness of the connection between the protrusion and the middle tube. Specifically, the distance between the second through hole and the protrusion can be within 10-30 mm, for example.

[0030] The term "axial" refers to a direction parallel to an axis, the term "radial" refers to a direction passing through and perpendicular to the axis, and the term "circumferential" refers to a direction around the axis. The above terms "axial", "radial" and "circumferential" do not limit the shape of the entity they describe, as long as the entity has an axis, for example, a square entity has a central axis. Accordingly, "axial", "radial" and "circumferential" can also be used to describe the corresponding directions based on the entity.

[0031] The term "ring" is a broader expression that includes "circular ring", and the shape it describes can be different types of rings such as circular ring, square ring, elliptical ring, etc.

[0032] The terms "inside" and "outside" refer to the inside and outside in the radial direction unless otherwise specified. Specifically, the inside refers to the direction closer to the middle tube, and the outside refers to the direction closer to the outside of the vending machine. The terms "top" and "bottom" refer to the height direction of the vending machine when it is in normal use.

[0033] <First Embodiment>

[0034] The utility model provides a rotary shelf 100 of an automatic vending cabinet. Figure 1 FIG. 1 is a schematic diagram of the structure of the rotary shelf 100 in the first embodiment of the present invention. Figure 1 The rotating shelf 100 shown is installed on a rotatable base, and the rotating shelf 100 is driven to rotate by a motor coupled to the base.

[0035] like Figure 1 As shown, the rotating shelf 100 includes a top plate 101 , a bottom plate 103 , layer partitions 105 , column partitions 107 , a middle tube 201 and a hoop 301 .

[0036] The middle cylinder 201 is a hollow cylindrical component arranged in the center of the rotating shelf 100, and has a cylindrical cylinder wall 203. The surface of the cylinder wall 203 is provided with a plurality of through holes, including a plurality of first through holes (not shown).

[0037] The top plate 101, the bottom plate 103 and the multiple partitions 105 are all arranged parallel to each other and separated from each other. The top plate 101, the bottom plate 103 and the partitions 105 are all circular, and the plate surface direction is perpendicular to the axial direction of the middle tube 201 (after being assembled into an automatic vending machine, the top plate 101, the bottom plate 103 and the multiple partitions 105 are all placed horizontally when the automatic vending machine is in normal use). The inner edges of the top plate 101, the bottom plate 103 and the partitions 105 are fixedly connected to the middle tube 201, and the outer edges are flush with each other. Storage space is formed between the top plate 101 and the partitions 105, between two adjacent partitions 105, and between the partitions 105 and the bottom plate 103.

[0038] The column partitions 107 start from the cylinder surface of the middle cylinder 201 and extend radially outward. Multiple column partitions 107 are radially distributed, and each layer of storage space is correspondingly divided into multiple radially distributed storage compartments 401. Each storage compartment 401 is in a fan-shaped shape. In this embodiment, each storage compartment 401 is of the same size and shape as an example for explanation, but in other embodiments, the number and installation position of the column partitions 107 can also be adjusted according to actual needs, so as to obtain storage compartments 401 of different sizes, so as to flexibly respond to the storage needs of different types of goods.

[0039] Figure 2 and Figure 3 They are schematic diagrams of the structures of the layer separator 105 and the column separator 107 in this embodiment. Figure 2 and Figure 3 , a plurality of first slots 109 are provided at the radial outer edge of the layer separator 105, and a plurality of second slots 111 are provided at the inner edge of the column separator 107. When the layer separator 105 and the column separator 107 need to be assembled together, the layer separator 105 and the column separator 107 are first placed orthogonally to each other, and then the first slots 109 of the layer separator 105 and the second slots 111 of the column separator 107 are aligned, and then the layer separator 105 and the column separator 107 are moved toward each other so that the layer separator 105 and the column separator 107 are inserted and fixed to each other. When the assembly is completed, the outer edge of the column separator 107 (the part with a solid body on the extension line of the second slot 111) is inserted into the first slot 109 of the layer separator 105, and the inner periphery of the layer separator 105 (the part with a solid body on the inner extension line of the first slot 109) is inserted into the second slot 111 of the column separator 107. Because the layer partition plates 105 and the column partition plates 107 are interlocked with each other, the extension ranges of the layer partition plates 105 and the column partition plates 107 in the radial direction overlap with each other, so that the layer partition plates 105 and the column partition plates 107 can play a role of stabilizing and supporting each other.

[0040] Preferably, the length of the first slot 109 is half of the width (in the radial direction) of the annular layer separator 105, and the length of the second slot 111 is half of the width (in the width direction) of the column separator 107, and the width of the layer separator 105 is equal to the width of the column separator 107. In the above manner, the layer separator 105 and the column separator 107 can be completely overlapped and inserted into each other, ensuring that the inner edges and outer edges of the layer separator 105 and the column separator 107 are flush with each other.

[0041] Figure 4 yes Figure 2 An enlarged view of the local structure of the outer edge of the layer partition 105. Figure 5 yes Figure 3 A partial enlarged view of the inner edge of the middle row of partitions 107. Figure 4 and Figure 5 In this embodiment, the width d1 of the first slot 109 and the width d2 of the second slot 111 are both 1.5-2 mm. The widths of the first slot 109 and the second slot 111 are compatible with the thickness of the layer partition 105 and the column partition 107, and should be suitable for the layer partition 105 or the column partition 107 to be inserted and interlocked with each other. The layer partition 105 and the column partition 107 both need to ensure a certain strength or thickness, so the width of the first slot 109 and the second slot 111 should not be too narrow; on the other hand, the thickness of the layer partition 105 and the column partition 107 should not be too thick. Too thick layer partitions 105 and column partitions 107 will cause a significant increase in the weight of the rotating shelf 100. Therefore, based on the above two points, in conjunction with the thickness of the layer partition 105 and the column partition 107, the width of the first slot 109 and the second slot 111 is preferably within the range of 1.5-2 mm.

[0042] refer to Figure 4 In this embodiment, the outer end of the first slot 109 further has a flared portion 113 whose width is larger than that of the first slot 109. The flared portion 113 is a notch structure with a gradually increasing diameter in the radial direction, which can guide the column partition 107 to a certain extent when the column partition 107 is inserted into the first slot 109, thereby improving the convenience of insertion and fixing.

[0043] refer to Figure 5 In this embodiment, one end of the second slot 111 also has an open structure 115 with a width greater than that of the second slot 111, so as to improve the convenience of assembly. In addition, the second through hole 119 on the column partition 107 is formed by cutting and folding a portion of the column partition 107, which is easier to process and has less influence on the strength of the column partition 107.

[0044] In this embodiment, the inner edges of the layer partitions 105 and the column partitions 107 are fixedly connected to the middle tube 201. Figure 3 and Figure 5 The inner edge of the column partition 107 is provided with a protrusion 117. When the assembly is completed, in the rotating shelf 100, the inner edge of the column partition 107 abuts against the outer surface of the tube wall 203 of the middle tube 201, and the protrusion 117 is inserted into the first through hole opened on the surface of the tube wall 203. Each column partition 107 is provided with a protrusion 117 at a position corresponding to the position between every two layers of partitions 105. The multiple protrusions 117 are distributed in the height direction, so that part of the weight of the column partition 107 can be borne by the middle tube 201, thereby playing a role in stably supporting the column partition 107 in the height direction.

[0045] In addition, reference Figure 1 and Figure 3 The column partitions 107 are further provided with second through holes 119 at positions corresponding to each other. Specifically, each column partition 107 is provided with a second through hole 119 between every two second slots 111, between the top second slot 111 and the top edge of the column partition 107, and between the bottom second slot 111 and the bottom edge of the column partition 107.

[0046] In this embodiment, the column partitions 107 are hooped together by passing through the second through holes 119 using a hoop ring 301. Specifically, taking the example of each column partition 107 having N second through holes 119, N hoop rings 301 are used to hoop together the column partitions 107. Each hoop ring 301 passes through the second through holes 119 located in the same layer (i.e., all pass through the second through holes 119 of the top layer, all pass through the second through holes 119 of the bottom layer, or pass through the second through holes 119 corresponding to the same two layer partitions 105) to hoop together the column partitions 107. For example, the method of hooping the column partitions 107 may be to first pass a strip-shaped hoop bar through each second through hole 119 in sequence, and then connect the ends of the hoop bars and tighten and fix them to form a hoop ring 301.

[0047] Because N hoops 301 are used to fix the column partitions 107 at different positions in the axial direction of the rotating shelf 100, the column partitions 107 and the middle cylinder 201 are subjected to a more uniform force. In addition, during the tightening process, as the radial dimension of the hoop 301 continues to decrease, the column partitions 107 can not only be tightened, but the hoop 301 can also apply a radially inward force to the column partitions 107. With the structure of the protrusion 117 on the inner edge of the column partition 107 inserted into the first through hole of the middle cylinder 201, the radially inward force can make the column partitions 107 and the middle cylinder 201 more tightly fixed, thereby ensuring the consistency of the product structure and size after assembly. The hoop 301 can be a hoop 301 made of plastic material or a hoop 301 made of metal material, as long as it has the required strength and ductility, which is not limited in this embodiment.

[0048] In this embodiment, reference Figure 3 , the second through hole 119 is arranged adjacent to the protrusion 117, and both are located at the inner edge of the column partition 107. In the direction in which the hoop 301 applies force, the position of the second through hole 119 and the position of the protrusion 117 correspond to each other. Specifically, the second through hole 119 and the protrusion 117 are both arranged near the midline position of two adjacent second slots 111. This adjacent and corresponding arrangement allows the radially inward force applied by the hoop 301 to the column partition 107 to be effectively transmitted to between the protrusion 117 and the middle tube 201, thereby ensuring the tightness of the connection between the protrusion 117 and the middle tube 201. Moreover, arranging the second through hole 119 at this position can also effectively shorten the required length of the hoop 301 and reduce the cost required to manufacture the hoop 301.

[0049] In some other embodiments, the protrusion 117 may not be centrally arranged, but may be configured to be arranged symmetrically along the midline at a position deviating from the midline of two adjacent second slots 111. In this way, the first through hole and other through holes correspondingly arranged on the middle tube 201 may be staggered to increase the strength of the middle tube 201.

[0050] Through the above method, the use of fasteners can be avoided or reduced, and the rotary shelf 100 of the vending machine can be assembled by simply splicing the partitions and tightening the hoop 301.

[0051] <Second Embodiment>

[0052] In a second embodiment of the present invention, a rotary shelf 100 of an automatic vending machine is provided. Figure 6 1 is a schematic structural diagram of a rotary shelf 100 in a second embodiment of the present invention. Figure 6 The structure of the rotating shelf 100 in this embodiment is substantially the same as that in the first embodiment. The main difference between the second embodiment of the present utility model and the first embodiment is that in the second embodiment, the rotating shelf 100 is further flexibly equipped with a grid plate 501 according to needs to adjust the size of the storage grid 401.

[0053] Specifically, in different usage scenarios, since the types of goods that the rotating shelf 100 needs to carry are different, the space required for each type of goods is also different. Due to the need to save costs and adopt a universal design, the number of first slots 109 opened on the layer partition 105 is usually fixed. For example, the design of 18 first slots 109 adopted in the first embodiment, correspondingly, the number of column partitions 107 that can be inserted and matched is also 18, that is, 17 independent storage compartments 401 can be separated in the circumferential direction of each layer. In the first embodiment, the size of each storage compartment 401 is fixed. If a certain type of goods does not require such a large space, it is difficult for the user or maintenance personnel to adjust the space.

[0054] In this embodiment, the size of the storage compartment 401 can be adjusted through the structural design of the layer partition 105 and the corresponding grid plate 501. Specifically, in this embodiment, each storage compartment 401 can be further divided into two sub-grid openings 403, and the volume of the storage compartment 401 is halved, so that a larger number of relatively small goods can be accommodated. It should be noted that, generally speaking, when selling goods, the vending machine will choose to open a specific storage compartment 401 or sub-grid opening 403 according to the actual payment or order of the user. The number of goods contained in the storage compartment 401 or sub-grid opening 403 determines the minimum unit that can be purchased. Generally speaking, the minimum unit that the user needs to purchase is all the goods in the storage compartment 401 or sub-grid opening 403. If the space of the storage compartment 401 or sub-grid opening 403 is too large, small-volume goods can only be sold in packages, affecting the user experience.

[0055] In this embodiment, the example of using a grid plate 501 to divide a storage compartment 401 into two sub-grid openings 403 is used for explanation, but it does not constitute a limitation on the way in which the grid plate 501 divides the storage compartment 401. In other embodiments, two or more grid plates 501 can be used to divide the same storage compartment 401, or grid plates 501 extending in the horizontal direction can be used to divide the storage compartment 401. The volume of each sub-grid opening 403 is also not limited to the case where the volume of the two sub-grid openings 403 is equal as exemplified in this embodiment, and sub-grid openings 403 with unequal volumes can be completely divided by adjusting the setting position of the grid plate 501.

[0056] In this embodiment, the grille plate 501 is detachably connected to the middle tube 201 and the layer separator 105. Specifically, the upper edge of the grille plate 501 is fixedly connected to the layer separator 105 at the top of the layer, the lower edge of the grille plate 501 is fixedly connected to the layer separator 105 at the bottom of the layer, and the inner edge of the grille plate 501 is fixedly connected to the middle tube 201.

[0057] Figure 71 is a schematic diagram of the fixing structure of the upper edge of the grid plate 501 and the top layer partition plate 105 in this embodiment. Figure 7 The upper edge of the grid plate 501 (i.e., the second end of the grid plate 501) has a threaded connection portion 503. Specifically, the upper edge of the grid plate 501 has a bending portion 505 that is bent laterally toward the grid plate 501. A through hole is provided on the bending portion 505. The threaded connection piece passes through the through hole and is threadedly connected to the top layer partition plate 105, thereby fixing the grid plate 501 to the top layer partition plate 105.

[0058] Figure 8 1 is a schematic diagram of the fixing structure of the lower edge of the grid plate 501 and the bottom layer partition plate 105 in this embodiment. Figure 4 and Figure 8 The partition plate 105 is provided with a slot 507 at a position suitable for setting the grid plate 501. The lower edge of the grid plate 501 (i.e., the first end of the grid plate 501) has a grid plate protrusion 509, which can be inserted into the slot 507 of the partition plate 105, thereby being limited and fixed with the partition plate 105.

[0059] In order to improve the commonality of the components, a threaded hole 511 is also provided on the side of the slot 507, adjacent to the slot 507. For the same layer partition 105, the threaded hole 511 can be used to fix the grid plate 501 below it, and the slot 507 can be used to fix the grid plate 501 above it. In this way, the upper grid plate 501 and the lower grid plate 501 will not interfere with each other, and each grid plate 501 can be fixed from both the upper and lower sides. In addition, with the above structure, when the grid plate 501 is not installed, the layer partition 105 is also relatively flat and smooth, which can facilitate the entry and exit of goods in the storage compartment 401.

[0060] Fig. 9 Schematic diagram of the structure of the grid plate 501 provided in the second embodiment of the present invention. Figure 6 and Fig. 9 The inner edge of the grid plate 501 has a grid plate avoidance opening 513. During installation, the middle tube 201, the layer partition 105, and the column partition 107 are first assembled and fixed, and tightened with the hoop 301, and then the grid plate 501 can be installed as needed. The grid plate avoidance opening 513 is a groove structure recessed in the inner edge of the grid plate 501. The setting height of the groove structure corresponds to the height of the second through hole 119. Specifically, in this embodiment, it is located in the width direction ( Figure 6The depth of the groove structure recessed into the inner edge of the grid plate 501 is suitable for making the grid plate 501 completely avoid the hoop 301, or slightly press the hoop 301. By providing the grid plate avoidance opening 513 at the position of the inner edge of the grid plate 501, on the one hand, the inner edge of the grid plate 501 can still be fixedly connected to the middle tube 201 to ensure the stability of the fixation of the grid plate 501; on the other hand, by avoiding the hoop 301, the installation of the grid plate 501 will not affect the main structure of the assembled rotating shelf 100, and the grid plate 501 can be added as needed after the rotating shelf 100 has been assembled as a whole.

[0061] Continue to refer Fig. 9 , the upper and lower ends of the inner edge of the grid plate 501 are provided with grid plate inner edge protrusions 515. Specifically, in this embodiment, the grid plate inner edge protrusions 515 are formed by cutting and bending the corners of the grid plate 501. When the rotating shelf 100 is assembled, the grid plate inner edge protrusions 515 protrude radially inward from the inner edge of the grid plate 501, and the grid plate inner edge protrusions 515 can be inserted into the third through hole (not shown in the figure) located on the cylinder wall 203 of the middle cylinder 201, so as to fix the grid plate 501 to the middle cylinder 201.

[0062] The grid plate 501 in this embodiment is fixedly connected to the middle tube 201 and the two layer partitions 105 by using the grid plate inner edge protrusion 515, the grid plate protrusion 509 and the threaded connection part 503, respectively, and the grid plate 501 is fixed from the upper side, the lower side and the inner side, respectively, which effectively improves the stability of the fixation of the grid plate 501. Moreover, the grid plate 501 can be flexibly selected according to the needs of the installation quantity, installation position, etc., and the flexibility is also good.

[0063] Through the above method, in this embodiment, the size of the storage compartment 401 can be adjusted by the grid plate 501. When a large storage compartment 401 is needed, the grid plate 501 can be discarded. When a small storage compartment 401 is needed, the grid plate 501 can be used to divide the storage compartment 401. In this way, the size of the storage compartment 401 can be flexibly adjusted according to the size of the goods to be placed, so that the rotating shelf 100 can adapt to more categories of goods and improve the efficiency of space utilization.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
