[0034] Figure 1 is a perspective view illustrating one embodiment of a height-adjustable assembly storage rack according to the present invention. Referring to Figure 1, the height-adjustable assembly storage rack 100 of the present invention includes a plurality of post components 110 and five storage layers 120, with sleeve members 122 at the four corners of each storage layer 120. Figure 1 shows a total of four post components 110, with the two front post components 110 spaced at a certain distance from each other, the two rear post components 110 spaced at a certain distance from each other, and the front and rear two post components 110 spaced at a certain distance from each other. These post components 110 are arranged in a rectangular or arbitrary shape. These five storage layers 120 are arranged sequentially between the post components 110 along the stacking direction L1, and these storage layers 120 have a structure that allows them to move along the height-adjustment direction LA, and are assembled between these post components 110 by the sleeve members 122. Therefore, these storage layers 120 have a structure that allows them to move along the vertical direction LA, and the height position of the storage layers 120 can be adjusted according to the dimensions of the items to be placed on them, improving usability. The number of storage layers 120 can be adjusted according to actual needs, so a wide variety of different combinations of height-adjustable assembly storage racks 100 can be configured.

[0035] Figure 2A is a perspective view illustrating the first support assembly according to the present invention. Figure 2B is a perspective view illustrating the second support assembly according to the present invention. Figure 3 is a perspective view illustrating the assembly process of the first and second support assemblies according to the present invention. Referring to Figures 1 to 3, the support assembly 110 of the present invention has a predetermined length, and the length of the support assembly 110 can be adjusted according to the height required for the actual height-adjustable assembly storage rack 100, and the support assembly 110 can achieve the predetermined length by assembly.

[0036] Using Figures 1, 2A, and 2B as examples, the support column assembly 110 has an upper end T1 and a lower end T2 opposite to the upper end T1. The support column assembly 110 can be divided into a first support column assembly 110A in Figure 2A and a second support column assembly 110B in Figure 2B. The leg column 170 is attached to the bottom 112D of the first support column assembly 110A, and the leg column 170 improves the overall stability of the elevating assembly storage rack 100 shown in Figure 1. The first support column assembly 110A has a lower end T2 and an assembly end TA2, where the lower end T2 and assembly end TA1 are the corresponding ends.

[0037] The second support assembly 110B has a lower end T1 and an assembly end TA1, and the upper end T1 and assembly end TA2 are the corresponding ends. The second support assembly 110B is installed on the connecting member 160, the position of the connecting member 160 is adjacent to the assembly end TA1, the assembly end TA1 of the second support assembly 110B faces the assembly end TA2 of the first support assembly 110A, and the connecting member 160 of the second support assembly 110B is assembled to the first support assembly 110A, thereby increasing the overall height of the support assembly 110 shown in Figure 1.

[0038] Specifically, the first support assembly 110A and the second support assembly 110B in the support assembly 110 each include a pipe member 112 and a plurality of locking holes 116, these locking holes 116 are provided penetrating the pipe member 112 at intervals, the locking holes 116 are along the longitudinal direction of the pipe member 112, the longitudinal direction is parallel to the assembly direction L2 (the assembly direction L2 is opposite to the stacking direction L1 shown in Figure 1), the locking holes 116 have opposing starting ends MA and ending ends MB, the dimensions of the starting end MA are larger than the dimensions of the ending end MB. In one embodiment, the cross-section of the ending end MB is a curved structure, and the cross-section of the starting end MA is a rectangular structure with an opening.

[0039] In one embodiment, along the assembly direction L2, the dimension of the locking hole 116 from the starting end MA to the ending end MB gradually decreases, that is, the dimension of the locking hole 116 along the assembly direction L2 is a tapered hole structure.

[0040] The tubular member 112 may be a rectangular tubular structure, and is a single rectangular tubular structure consisting of a first plate 112A, a second plate 112B, a third plate 112C, and an assembly plate DA. The first plate 112A and the second plate 112B are parallel to each other, the third plate 112C and the assembly plate DA are parallel to each other, both sides of the third plate 112C are connected to the first plate 112A and the second plate 112B respectively, and both sides of the assembly plate DA are connected to the first plate 112A and the second plate 112B respectively, and the first plate 112A, the second plate 112B, the third plate 112C, and the assembly plate DA are connected to a single rectangular tubular three-dimensional structure. The first plate 112A and the second plate 112B are on opposite sides, and the assembly plate DA and the third plate 112C are on opposite sides. Furthermore, the internal space composed of the first plate 112A, the second plate 112B, the third plate 112C, and the assembly plate DA has a hollow section LD, that is, a hollow section LD within the tubular member 112, and is a hollow tube.

[0041] As shown in Figure 3, the connecting member 160 can be assembled into the hollow section LD inside the pipe member 112, where the hollow section LD is the space inside the pipe member 112. The connecting member 160 is inserted into the hollow section LD and assembled inside the pipe member 112, thereby assembling the second support assembly 110B and the first support assembly 110A into one.

[0042] These locking holes 116 are provided at different positions on the assembly plate DA of the pipe member 112, spaced apart from each other. The structural form of the connecting member 160 can be adjusted according to the structural form of the pipe member 112. For example, the assembly plate DA of the pipe member 112 has a plurality of inclined plates 118 installed, each inclined plate 118 provided at one end of the locking hole 116, and as shown in Figure 3, the inclined plate 118 is connected to the starting end MA of the locking hole 116, the inclined plate 118 is a plate formed by bending from the starting end MA of the locking hole 116, and the inclined plate 118 is inclined toward the hollow part LD inside the pipe member 112 such that the inclined position of the inclined plate 118 is located in the hollow part LD. Therefore, the connecting member 160 is a concave member 162, and protruding members 162A are provided at both ends of the concave member 162, making the concave member 162 concave and avoiding the installation position of the inclined plate 118. In embodiments not shown, if an inclined plate is not installed on the pipe member, the connecting member can be adjusted to a non-concave member depending on the structural type of the pipe member.

[0043] Figure 4A is an exploded view illustrating the lower end of the assembly fixing member and support column assembly according to the present invention. Figure 4B is an exploded view illustrating the upper end of the pipe member and assembly fixing member according to the present invention. Figure 4C is a perspective view illustrating the assembly fixing member according to the present invention. Referring to Figures 1 and 4A to 4C, the liftable assembly storage rack 100 of the present invention further includes a plurality of assembly fixing members 140 in addition to the support column assembly 110 and storage layer 120, of which holes BA are provided at the upper end T1 and lower end T2 of each support column assembly 110, respectively, to which the assembly fixing member 140 is assembled.

[0044] Referring to Figures 1 and 4A, the upper ends T1 and T2 of the support assembly 110 are each attached to one assembly fixing member 140, and the assembly fixing member 140 is assembled from the third plate 112C of the pipe member 112. The third plate 112C has multiple holes BA installed, that is, the holes BA and the aforementioned locking holes 116 are located on opposite sides of the pipe member 112 (the third plate 112C and the assembly plate DA), respectively. The assembly fixing member 140 has assembled column bodies 146 installed, and the assembled column bodies 146 are attached to the holes BA, and the assembly fixing member 140 is attached to the upper end T1 and lower end T2 of the support assembly 110. The number and structural form of the assembled column bodies 146 are matched to the number and structural form of the holes BA on the third plate 112C. In this embodiment, there is one assembled column 146, and the structural form of the assembled column 146 is a long column, and one corresponding hole BA is provided, and the structural form of hole BA is a long hole that can fit into the long column.

[0045] In one embodiment, the assembly fixing member 140 is U-shaped and includes a bottom plate 142, a first side plate 144A, a second side plate 144B, and one assembly column 146, where both sides of the bottom plate 142 are perpendicularly connected to the first side plate 144A and the second side plate 144B, respectively, and the first side plate 144A and the second side plate 144B are opposite sides. The assembly column 146 is installed so as to protrude from the inner surface of the bottom plate 142.

[0046] Taking Figure 4A as an example, the assembly fixing member 140 is assembled from the third plate 112C of the pipe member 112. That is, if the assembly plate DA is defined as the front position of the pipe member 112, the assembly fixing member 140 is attached to the rear position of the pipe member 112. The first side plate 144A, the second side plate 144B, and the bottom plate 142 of the assembly fixing member 140 correspond to the first plate 112A, the second plate 112B, and the third plate 112C of the pipe member 112, respectively, and the position of the assembly column 146 corresponds to the hole BA on the third plate 112C.

[0047] When the assembly fixing member 140 moves in the direction of the third plate 112C, the assembled column 146 is attached to the hole BA, the first side plate 144A is attached to the surface of the first plate 112A, the second side plate 144B is attached to the surface of the second plate 112B, and the bottom plate 142 is attached to the surface of the third plate 112C. The assembly fixing member 140 is then assembled to the pipe member 112, and the assembled state is shown in Figure 7. Similarly, the structure and process for assembling the assembly fixing member 140 in Figure 4B to the third plate 112C of the pipe member 112 is as shown in Figure 4A. The assembly fixing member 140 is installed at the upper end T1 and lower end T2 of the support column assembly 110. Therefore, although the assembly plate DA has multiple locking holes 116, only the positions of two locking holes 116 (located at the upper end T1 and lower end T2 of the support column assembly 110) correspond to the assembly fixing member 140.

[0048] Figure 5 is a perspective view illustrating the storage layer of the present invention. Refer to Figures 1 and 5. The storage layer 120 of the present invention includes a movable shelf 121 and four sleeve members 122, of which the movable shelf 121 is, for example, a mesh shelf. These four first sleeve members 122 are provided at the four corners of the movable shelf 121. The sleeve members 122 are, for example, rectangular sleeves that are substantially rectangular and have a hollow structure.

[0049] The storage layer 120 of the present invention includes a movable shelf 121, four sleeve members 122, and four assembly members 124, of which the movable shelf 121 is, for example, a mesh shelf. The four first sleeve members 122 are provided at each of the four corners of the movable shelf 121. The sleeve members 122 are, for example, rectangular sleeves that are substantially rectangular, and the sleeve members 122 have a hollow structure and a housing section CA. Each sleeve member 122 is installed on an assembly member 124, and a protruding column MC is installed on one side of the assembly member 124 (see Figures 7 and 8), and the protruding column MC is located inside the housing section CA within the sleeve member 122. In one embodiment, the sleeve member 122 may be the body of a rectangular sleeve, with four plates connected to form a hollow rectangular structure, and the housing section CA is the space inside the rectangular sleeve of the sleeve member 122, but the present invention is not limited thereto, and the assembly members may be of any other shape, or the shape of the assembly members can be adjusted according to the structural form of the pipe members.

[0050] Figure 6 is a perspective view illustrating the process by which the storage layer of the present invention is attached to the locking hole at the lower end of the support assembly and the assembly fixing member. Figure 7 is a partially enlarged perspective view illustrating the process by which the storage layer of the present invention is attached to the locking hole at the lower end of the support assembly and the assembly fixing member. Figure 8 is a partially enlarged perspective view illustrating the storage layer of the present invention attached to the locking hole of the support assembly. Since the assembly fixing member 140 is installed at the upper end T1 and lower end T2 of the support assembly 110, the assembly process by which the storage layer 120 of the present invention is attached to the lower end T2 of the support assembly 110, and the coupling structure with the locking hole 116 and the assembly fixing member 140 of the sleeve member 122, respectively, will be explained with reference to Figures 6 to 8. The process by which the storage layer 120 is attached to the upper end T1 of the support assembly 110 is the same as that for the lower end T2, so the details will not be repeated.

[0051] The dimensions of the sleeve member 122 of the present invention are larger than the dimensions of the pipe member 112 of the support assembly 110, and the dimensions of the protruding column MC are smaller than the dimensions of the starting end MA of the locking hole 116, allowing the protruding column MC to move along the assembly direction L2 from the starting end MA to the ending end MB of the locking hole 116, and the dimensions of the protruding column MC substantially conform to the dimensions of the ending end MB of the locking hole 116, allowing the protruding column MC to be fixed to the ending end MB. The storage layer 120 moves along the assembly direction L2, which is opposite to the stacking direction L1 as shown in Figure 1, and the rectangular sleeve structure of the sleeve member 122 is fitted to the outside of the pipe member 112, and the protruding column MC of the assembly member 124 moves in the direction facing the locking hole 116 (i.e., the first assembly direction L2). The storage layer 120 continues to move along the first assembly direction L2, moving the protruding column MC in the assembly member 124 along the starting end MA of the locking hole 116 until the protruding column MC is locked to the ending end MB of the locking hole 116, thereby fixing the storage layer 120 at the lower end T2 of the pipe member 112 of the support column assembly 110.

[0052] In one embodiment, as the aforementioned storage layer 120 continues to move along the first assembly direction L2, the upper end T1 and lower end T2 of the support column assembly 110 are each fitted with assembly fixing members 140, and the protruding column MC of the sleeve member 122 is fixed in the locking hole 116, while the sleeve member 122 is attached to the outer surface of the corresponding assembly fixing member 140. The first side plate 144A, the second side plate 144B, and the bottom plate 142 of the assembly fixing member 140 are attached to the inner surface of the sleeve member 122, and the assembly fixing member 140 is positioned in the housing CA within the sleeve member 122, improving the stability of the storage layer 120 being installed at the upper end T1 and lower end T2 of the support column assembly 110.

[0053] Although no assembly fixing member 140 is attached between the upper end T1 and lower end T2 of the support assembly 110 of the present invention, the assembly process of the coupling structure in which the storage layer 120 in Figure 7 is attached to the sleeve member 122 and locking hole 116 of the support assembly 110 is the same as the assembly process in which the storage layer 120 in Figure 8 is assembled to the sleeve member 122 and locking hole 116 of the support assembly 110. After the storage layer 120 is assembled to the lower end T2 of the support assembly 110 by the sleeve member 122, the dimensions of the sleeve member 122 of the present invention are larger than the dimensions of the pipe member 112 of the support assembly 110, and another storage layer 120 is moved along the pipe member 112 in the assembly direction L2, and the rectangular sleeve structure of the sleeve member 122 is fitted to the outside of the pipe member 112, and has one movable space, the movable space is the space formed between the sleeve member 122 and the pipe member 112. The protruding column MC faces the locking hole 116 and moves in the direction of the locking hole 116 (i.e., the assembly direction L2). As the storage layer 120 continues to move along the assembly direction L2, it moves the protruding column MC in the assembly member 124 along the starting end MA of the locking hole 116 until the protruding column MC is locked to the ending end MB of the locking hole 116, thereby fixing the storage layer 120 to the pipe member 112 in the support column assembly 110.

[0054] Furthermore, as the aforementioned storage layer 120 continues to move along the assembly direction L2, and the dimensions of the locking holes 116 along the assembly direction L2 are tapered, the dimensions of the starting end MA of the locking holes 116 gradually decrease to the dimensions of the ending end MB. As the protruding column MC moves along the assembly direction L2 from the starting end MA to the ending end MB, the tightness of the connection between the protruding column MC and the locking holes 116 gradually increases, making it easier for the protruding column MC to enter the locking holes 116. As the protruding column MC continues to move along the assembly direction L2, the dimensions of the locking holes 116 gradually decrease, firmly fixing the protruding column MC within the locking holes 116 and allowing the assembler to know when the assembly is complete.

[0055] Figure 9 is a perspective view illustrating the process of attaching the storage layer according to the present invention to the upper end of the support assembly and the assembly fixing member. Figure 10 is a partial perspective view illustrating the process of attaching the storage layer according to the present invention to the upper end of the support assembly and the assembly fixing member. As shown in Figures 1, 9, and 10, after assembling the three storage layers 120 above the lower end T2 of the support assembly 110 in order, one storage layer 120 is assembled to the upper end T1 of the support assembly 110, and the assembly process is the same as in Figure 8 described above. As shown in Figure 10, the locking hole 116 here has a tapered hole structure, and the locking hole 116 has an end end MA installed, but does not have an inclined plate 118, and the protruding column MC continues to move along the assembly direction L2, and the dimensions of the locking hole 116 gradually decrease, so that the protruding column MC can be firmly fixed to the end end MB of the locking hole 116.

[0056] As can be seen from this, the dimensions of the sleeve member 122 of the storage layer 120 of the present invention are larger than the dimensions of the pipe member 112 of the support column assembly 110. Therefore, these storage layers 120 can be moved up and down relative to the support column assembly 110 along the vertical direction LA. During the movement process along the assembly direction L2, the storage layer 120 is assembled to the support column assembly 110, and assembly fixing members are installed at the upper end T1 and lower end T2 of the support column assembly 110, thereby improving the stability of assembling the storage layer 120 to the support column assembly 110.

[0057] Furthermore, as shown in Figures 7 and 8, in the process of adjusting the movement of the storage layer 120 relative to the support column assembly 110 along the stacking direction L1, the protruding column MC of the assembly member 124 can move the storage layer 120 along the inclined structure of the inclined plate 118.

[0058] Figure 11 is an enlarged perspective view of the lid member and assembly member of the present invention. Referring to Figures 1 and 11, in one embodiment, the lid member 180 can be added on top of the support column assembly 110 to cover the hollow portion LD above the support column assembly 110 and improve the appearance. The lid member 180 may include a connecting structure 182, the structural form of which the connecting structure 182 matches the structural form of the hollow portion LD, and the connecting structure 182 can be inserted into the hollow portion LD to attach the lid member 180 to the support column assembly 110.

[0059] Figures 1 to 11 above illustrate an example where the pipe member 112 of the support assembly 110 is a square pipe structure. However, the present invention is not limited to this, and the structure of the support assembly of the present invention can also be applied to a round pipe structure. This will be illustrated below with reference to Figures 12 to 18.

[0060] Figure 12 is a perspective view illustrating another embodiment of the elevating assembly storage rack according to the present invention. Referring to Figure 12, the elevating assembly storage rack 200 of the present invention includes a plurality of column assemblies 210, five storage layers 220, and each storage layer 220 has sleeve members 222 at the four corners. Figure 12 has a total of four column assemblies 210, with two front column assemblies 210 spaced at a certain distance from each other, two rear column assemblies 210 spaced at a certain distance from each other, and two front and rear column assemblies 210 spaced at a certain distance from each other. These column assemblies 210 are arranged in a rectangular or arbitrary shape, and leg columns 170 are provided below the column assemblies 210, and the leg columns 170 improve the overall stability of the elevating assembly storage rack 200 shown in Figure 12. The support column assembly 210 has an upper end T11 and a lower end T12 opposite to the upper end T11, the storage layer 220 can be divided into a first storage layer 220A and a second storage layer 220B, and the sleeve member 222 can be divided into a first sleeve member 222A and a second sleeve member 222B, with the first sleeve member 222A installed at the four corners of the first storage layer 220A and the second sleeve member 222B installed at the four corners of the second storage layer 220B.

[0061] These five storage layers 220 are positioned sequentially between the support column assemblies 110 along the stacking direction L1. The upper end T11 and lower end T12 of the support column assemblies 210 correspond to the first storage layer 220A and four first sleeve members 222A connected to the first storage layer 220A. Three second storage layers 220B and second sleeve members 222B connected to the second storage layers 220B are installed between these two first storage layers 220A.

[0062] These storage layers 220 have a structure that allows them to move along the vertical direction LA and can be assembled between these column assemblies 210 by sleeve members 222. Therefore, these storage layers 220 have a structure that allows them to move along the vertical direction LA and the height position of the storage layers 120 can be adjusted according to the actual situation to improve usability. Since the number and type of storage layers 220 can be adjusted according to the actual needs, multiple different combinations of height-adjustable assembly storage racks 200 can be configured.

[0063] The support assembly 210 of this embodiment includes a pipe member 212 and a plurality of locking holes 216. The pipe member 212 is a round pipe structure and is a hollow pipe. By adding a cover member 280 on top of the support assembly 210, the cover member 280 is adjusted to match the shape and structure of the pipe member 212, and the cover member 280 is assembled to the support assembly 210. These locking holes 216 are provided at intervals on the pipe member 212, and the locking holes 216 are provided along the length direction of the pipe member 212, the length direction is parallel to the assembly direction L2 (the assembly direction L2 is opposite to the stacking direction L1 shown in Figure 12), and the locking holes 216 have opposing starting ends MA2 and ending ends MB2, with the dimension of the starting end MA2 being larger than the dimension of the ending end MB2. In one embodiment, the dimension of the locking hole 216 from the starting end MA2 to the ending end MB2 gradually decreases along the assembly direction L2, that is, the dimensions of the locking hole 216 along the assembly direction L2 have a tapered hole structure. In one embodiment, the cross section of the ending end MB2 is a rectangular structure with an opening, and the cross section of the starting end MA2 is a curved structure (see Figure 16 or Figure 17).

[0064] Figure 13 is an exploded view of the lower end of the assembly fixing member and support column assembly according to the present invention. The liftable assembly storage rack 200 of the present invention further includes a plurality of assembly fixing members 240 in addition to the support column assembly 210 and storage layer 220, of which two holes BA2 are provided at the upper end T11 and lower end T12 of each support column assembly 210, to which the assembly fixing member 240 is attached. In addition, the assembly fixing member 240 of this embodiment can be provided with another locking hole 241, that is, two holes BA2 are provided at the upper end T11 and lower end T12 of each support column assembly 210, and a locking hole 216 is provided between the upper end T11 and lower end T12. The locking hole 241 is the same as the locking hole 216, and the dimensions of the locking hole 241 gradually decrease along the assembly direction L2, so that the locking hole 241 has an end end MB1.

[0065] The assembly fixing member 240 is provided on the outer surface of the pipe member 212 at the upper end T1 and lower end T2 of the support column assembly 110. The assembly fixing member 240 has two assembled column bodies 246 installed on it, and these two assembled column bodies 246 are assembled into corresponding holes BA2, and the assembly fixing member 240 is assembled to the pipe member 212. Furthermore, since the pipe member 212 in this embodiment has a round pipe structure, one embodiment of the assembly fixing member 240 may include two semicircular members 242, and one assembled column body 246 is installed on the inner surface of each of these two semicircular members 242, the structural form of the assembled column body 246 is an elongated column body, and the structural form of the hole BA2 may be an elongated hole to match the aforementioned elongated column body.

[0066] In one embodiment, the two semicircular members 242 are assembled to the outer surface of the pipe member 212 by interlocking with each other. For example, a convex block 242A and a concave block 242B are installed on both sides of the semicircular member 242, and the convex block 242A of one semicircular member 242 interlocks with the concave block 242B of another semicircular member 242, and the concave block 242B of one semicircular member 242 interlocks with the convex block 242A of another semicircular member 242. In this configuration, the assembled column 246 of one semicircular member 242 is attached to the corresponding hole BA2, the assembled column 246 of another semicircular member 242 is attached to the corresponding hole BA2, and the convex block 242A and concave block 242B of one semicircular member 242 are assembled to the corresponding concave block 242B and convex block 242A of the other semicircular member 242, respectively, and these two semicircular members 242 are assembled to the pipe member 212. The above example uses the position of the lower end T12 of the support column assembly 210, but similarly, the fact that the assembly fixing member 240 at the upper end T11 of the support column assembly 210 is provided on the pipe member 212 of the support column assembly 110 is the same as the fact that the assembly fixing member 240 at the lower end T12 of the support column assembly 210 is provided on the support column assembly 110 of the pipe member 212, so it will not be explained again.

[0067] Figure 14 is a partially enlarged perspective view illustrating the process of assembling the first storage layer according to the present invention to the locking hole at the lower end of the support assembly and the assembly fixing member. Figure 15 is a partially enlarged perspective view illustrating the first storage layer according to the present invention attached to the locking hole of the support assembly. Referring to Figures 14 and 15, the assembly process in which the first sleeve member 222A of the storage layer 220 of the present invention is assembled to the lower end T12 of the support assembly 210, and the coupling structure of the first sleeve layer 222A of the sleeve member 222 and the locking hole 241 of the assembly fixing member 240 will be explained. However, the process of attaching the first storage layer 220A to the upper end T11 of the support assembly 210 is the same as that for the lower end T12, so it will not be explained repeatedly here.

[0068] The first storage layer 220A of the storage layer 220 includes a movable shelf 221 and four first sleeve members 222A, each of which is installed at one of the four corners of the movable shelf 221. The first sleeve members 222A are substantially circular sleeves and have a hollow structure with a housing section CA1. An assembly member 224A is installed on each first sleeve member 222A, and a protruding column MC1 is installed on one side of the assembly member 224A (see Figure 15). The protruding column MC1 is a recessed structure that is recessed into the outer surface of the sleeve member 222, and the protruding column MC1 is located inside the first sleeve member 222A.

[0069] The dimensions of the first sleeve member 222A of the present invention are larger than the dimensions of the pipe member 212 of the support assembly 210, the first storage layer 220A moves along the assembly direction L2, which is opposite to the stacking direction L1 in Figure 12, and the circular sleeve structure of the first sleeve member 222A is fitted to the outside of the pipe member 212, and the protruding column MC1 in the assembly member 224A moves toward the locking hole 241 (i.e., the same as the assembly direction L2) facing the locking hole 241. The first storage layer 220A continues to move along the assembly direction L2 until the protruding column MC1 locks into the end MB1 of the locking hole 241, fixing the first storage layer 220A at the lower end T12 of the pipe member 212 of the support assembly 110.

[0070] Therefore, since the dimensions of the first sleeve member 222A of the first storage layer 220A of the present invention are larger than the dimensions of the pipe member 212 of the support column assembly 210, the first storage layer 220A can move up and down along the vertical direction LA relative to the support column assembly 210, and during the movement process along the assembly direction L2, the first storage layer 220A can be assembled onto the support column assembly 210, and by installing assembly fixing members 240 at the upper end T1 and lower end T2 of the support column assembly 210, the stability of the storage layer 220 being assembled onto the support column assembly 210 can be improved.

[0071] Figure 16 is a partially enlarged perspective view illustrating the process of attaching the second storage layer according to the present invention to the locking hole of the support column, and Figure 17 is a partially enlarged perspective view illustrating the second storage layer according to the present invention attached to the locking hole of the support column. In Figures 16 and 17, second sleeve members 222B are provided at the four corners of the second storage layer 220B of this embodiment. The second sleeve members 222B are substantially circular sleeves and have a hollow structure with a housing section CA2. An assembly member 224B is installed on each second sleeve member 222B. The assembly member 224B is a protruding column extending toward the housing section CA2, and the protruding column is located inside the second sleeve member 222B.

[0072] The dimensions of the second sleeve member 222B of the present invention are larger than the dimensions of the pipe member 212 of the support assembly 210, the second storage layer 220B moves along the assembly direction L2, the assembly direction L2 is opposite to the stacking direction L1 as shown in Figure 12, and the circular sleeve structure of the second sleeve member 222B is fitted to the outside of the pipe member 212, the assembly member 224B faces the locking hole 216 and moves in the direction of the locking hole 216 (i.e., the same as the assembly direction L2). As the assembly member 224B moves from the starting end MA2 to the ending end MB2, the tightness of the connection between the assembly member 224B and the locking hole 216 gradually increases, making it easier for the assembly member 224B to enter the locking hole 216. As the assembly member 224B continues to move along the assembly direction L2, the dimensions of the locking hole 216 gradually decrease, firmly fixing the assembly member 224B within the locking hole 216, allowing the assembler to know when the assembly is complete, and fixing the second storage layer 220B to the pipe member 212 of the support assembly 210.

[0073] Furthermore, the support column assembly 210 can achieve a predetermined length by the assembly method shown in Figures 2A and 2B. In one embodiment, Figure 18 is a perspective view illustrating the assembly process of the first and second support column assemblies of the present invention. Referring to Figure 18, one end of the second support column assembly 210B is connected to a connecting member 260, the connecting member 260 is provided with a recess 264, and a protruding fixing member EA is installed in the hollow portion LD2 of the first support column assembly 210A. In this way, the recess 264 is fitted into the protruding fixing member EA, the connecting member 260 is inserted into the hollow portion LD2, and the first support column assembly 210A and the second support column assembly 210B are assembled into one.

[0074] In summary, the elevating assembly storage rack of the present invention has a simple assembly structure, is relatively stable, and allows the storage layers to move along the vertical direction within the support column assembly, thereby improving overall usability.

[0075] Furthermore, because the dimensions of the locking holes along the assembly direction are tapered, the present invention ensures that as the protruding column moves along the assembly direction, the tightness of the connection between the protruding column and the locking hole gradually increases, making it easier for the protruding column to enter the locking hole. As the protruding column continues to move along the assembly direction, the dimensions of the locking hole gradually decrease, firmly fixing the protruding column within the locking hole and allowing the assembler to know when assembly is complete.

[0076] Furthermore, assembly fixing members are installed at the upper and lower ends of the support column assembly, and the protruding column of the sleeve member is firmly fixed to the locking hole. In addition, the assembly fixing members are located in the housing portion of the sleeve member, improving the stability of the storage layer being installed on the support column assembly.

[0077] Furthermore, since the dimensions of the sleeve member of the storage layer of the present invention are larger than the dimensions of the pipe member of the support column assembly, the storage layer can move up and down in the vertical direction relative to the support column assembly. During the process of moving along the assembly direction, the storage layer is assembled to the support column assembly, and by installing assembly fixing members at the upper and lower ends of the support column assembly, the stability of the storage layer being assembled to the support column assembly is improved.

[0078] Although the present invention has been disclosed by embodiments as described above, this does not limit the invention, and those skilled in the art can make some modifications and alterations without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be based on the claims defined below. [Explanation of symbols]
