Description

Technical Field

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

[0002] Box shelving is a modular metal shelving system designed for storing boxed goods. It is mainly composed of uprights, beams, diagonal braces, and shelves. The various components are assembled to form a multi-layer load-bearing structure, and it is widely used in warehouses, workshops, and other places to store various boxed goods.

[0003] Existing box shelving typically uses integrated fixed grid structures or flat panel structures for its shelves, which only provide load-bearing support for the boxes. However, in actual working environments such as warehouses or factories, these load-bearing structures obstruct the bottom space of the boxes. This means that when it comes to handling some heavy or large boxes, forklifts cannot be used for loading and unloading, requiring manual handling. This not only significantly increases labor intensity but also significantly reduces the efficiency of goods turnover. Utility Model Content

[0004] The main purpose of this utility model is to provide a box shelf structure that avoids obstructing the bottom space of goods, allowing loading and unloading tools to extend from under the supporting structure to lift the goods, thereby reducing labor intensity and improving the turnover efficiency of goods.

[0005] To achieve the above objectives, this utility model proposes a box shelf structure, including several sets of spaced upright components and a first crossbeam connecting two adjacent sets of upright components; the first crossbeam and the corresponding two adjacent sets of upright components form a frame structure with at least one side open and unobstructed; it also includes at least one set of load-bearing components, each load-bearing component including a pair of load-bearing members with planar load-bearing surfaces on their tops, the pair of load-bearing members being symmetrically arranged on opposite sides of two adjacent sets of upright components, forming a load-bearing structure with a support gap in the middle, the support gap being used for external loading and unloading tools to lift and move goods on the load-bearing structure from below.

[0006] In one possible implementation, adjacent upright assemblies are spaced apart along the width of the shelf; each group of upright assemblies includes several uprights spaced apart along the depth of the shelf, and adjacent uprights of the same upright assembly are connected to each other by support members.

[0007] In one possible implementation, the support member and the column are fixedly connected by a first connecting structure, and are detachable from each other.

[0008] In one possible implementation, the first connection structure includes a first connection hole disposed on one side of the column and a first locking pin protruding on the support member; a plurality of the first connection holes are provided and are spaced apart along the length of the column.

[0009] In one possible implementation, the first connecting structure further includes a plurality of first pin holes disposed on the column, the plurality of first pin holes being disposed on the same side as the first connecting holes and corresponding one-to-one with the first connecting holes; the bearing member is provided with a first positioning hole corresponding to the first pin hole, and the first positioning hole and the first pin hole are connected by a positioning pin.

[0010] In one possible implementation, the two ends of the first crossbeam are respectively connected to the adjacent columns of two adjacent column assemblies by a second connecting structure; the second connecting structure includes a plurality of second connecting holes disposed on one side of the column and a second locking pin disposed at both ends of the first crossbeam; the plurality of second connecting holes are spaced apart along the length of the column, and the second locking pin engages with the second connecting holes.

[0011] In one possible implementation, the support member is a diagonal brace; the diagonal brace is provided with a third connecting hole at both ends, and the column is provided with a fourth connecting hole. When the third connecting hole and the fourth connecting hole are in corresponding positions, they can be fixed to each other by a connector.

[0012] In one possible implementation, the column includes a main body and bent portions disposed on both sides of the main body, wherein a limiting groove is formed between the bent portions and the main body; the first pin hole and the first positioning hole are symmetrically disposed on the bent portions on both sides; and the second connecting hole is disposed on the main body.

[0013] In one possible implementation, an assembly is also included, through which the upper and lower ends of the two columns can be fixedly connected to each other to increase the height of the columns.

[0014] In one possible implementation, the assembly includes a connecting plate and a fixing member. The connecting plate is shaped and sized to match the end of the column to fit against the outer or inner surface of the column. Both the connecting plate and the column are provided with corresponding through holes. The fixing member fixes the connecting plate and the column through the through holes.

[0015] Compared to existing technologies, this application utilizes a pair of symmetrically arranged load-bearing members to form a central support gap, with at least one side of the frame structure being unobstructed and open. This allows forklifts and other loading / unloading tools to directly extend into the support gap from below the load-bearing structure to lift goods, completely avoiding the problem of existing shelves obstructing the bottom space. It eliminates the need for manual handling of heavy or large containers, reducing labor intensity and significantly improving the efficiency of loading, unloading, and turnover of goods, thus meeting the high-efficiency operational needs of warehouses, workshops, and other similar settings.

[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] Example 1

[0033] Reference Figures 1 to 7 This embodiment discloses a box shelf, including several sets of spaced upright components and a first crossbeam 1 connecting two adjacent sets of upright components.

[0034] Specifically, such as Figure 2 As shown, adjacent upright assemblies are spaced apart along the width of the shelf; each group of upright assemblies includes several uprights 2 spaced apart along the depth of the shelf. In this embodiment, the upright assemblies are configured in at least two groups, and each group of upright assemblies has at least two uprights 2. Adjacent uprights 2 in adjacent upright assemblies are connected by a first crossbeam 1, and adjacent uprights 2 in the same upright assembly are connected to each other by a support member; wherein the support member can be a diagonal brace 8 or a second crossbeam 5.

[0035] The most basic frame structure can be formed by the first crossbeam 1, the second crossbeam 5 and at least four columns 2, and at least one side of the frame structure is provided with an unobstructed open opening, which can be used by users to place goods.

[0036] For the other three sides, baffles 13, diagonal braces 8, or second crossbeams 5 can be installed to prevent goods from falling out from the other three sides. Furthermore, the baffles 13 or diagonal braces 8 can also enhance the connection stability and strength of the shelving.

[0037] The column 2 includes a main body 20 and bent portions 21 disposed on both sides of the main body 20. The bent portions 21 are integrally formed with the main body 20, and a limiting groove 14 is formed between them. By setting the bent portions 21 and the main body 20, the contact area between the bottom of the column 2 and the ground can be increased, thereby enhancing the placement stability of the column 2.

[0038] like Figure 2-3 As shown, it also includes at least one set of bearing components. The bearing components include at least one pair of bearing members 3 with planar bearing surfaces on the top. The pair of bearing members 3 are symmetrically arranged on opposite sides of two adjacent sets of column components to form a bearing structure with a support gap 4 in the middle. The cross-section of the bearing member 3 is L-shaped and has a long strip structure. One side of the bearing member 3 is attached to the column 2 and fixedly connected by the first connecting structure 6, and the bearing members are detachable from each other. The other side extends horizontally in the direction of the support gap 4 to form a support part for supporting the goods.

[0039] The first connecting structure 6 includes a first connecting hole 60 disposed on one side of the column 2 and a first locking pin 61 protruding on the support member 3; a plurality of first connecting holes 60 are distributed at intervals along the length direction of the column 2. Specifically, the first connecting holes 60 are disposed on the two bent portions 21 on both sides of the column 2. The bent portions 21 are perpendicular to the main body 20, so that the first connecting holes 60 face the side of the adjacent column assembly, allowing the end of the support member 3 to stably fit with the bent portion 21 of the column 2, thereby improving the installation stability of the support member 3.

[0040] In this embodiment, the first connecting hole 60 is a gourd-shaped hole with a larger upper diameter and a smaller lower diameter, while the first locking pin 61 has an I-shaped cross-section. One end of the first locking pin 61 is fixed to the end of the support member 3, and the other end is circular, with its outer diameter being larger than the smallest inner diameter of the gourd-shaped hole and smaller than the largest inner diameter of the gourd-shaped hole, so that it can be inserted into the first connecting hole 60 and achieve a locking connection with the first connecting hole 60. In this embodiment, the first locking pin 61 is fixed to the support member 3 by riveting, but other connection methods can also be used, which will not be described in detail in this application.

[0041] When it is necessary to disassemble the bearing 3, slide the first locking pin 61 toward the larger hole in the gourd hole to remove it from the gourd hole.

[0042] Meanwhile, in order to improve the connection stability between the bearing member 3 and the column 2 and to prevent the bearing member 3 from detaching from the first connecting hole 60 due to vibration or external force during use, a number of first pin holes 62 are also provided on the column 2. The number of first pin holes 62 are provided on the same side as the first connecting hole 60 and correspond one-to-one with the first connecting hole 60. The bearing member 3 is provided with a first positioning hole 63 corresponding to the first pin hole 62. The first positioning hole 63 and the first pin hole 62 are connected by a positioning pin 64. The positioning pin 64 can realize the limiting and fixing between the bearing member 3 and the column 2, thereby preventing relative movement between the bearing member 3 and the column 2.

[0043] Furthermore, such as Figure 4 As shown, the two ends of the first crossbeam 1 are respectively connected to the adjacent columns 2 of two adjacent column assemblies through the second connecting structure 7; the second connecting structure 7 includes a plurality of second connecting holes 70 disposed on one side of the column 2 and a second locking pin 71 disposed at both ends of the first crossbeam 1; the plurality of second connecting holes 70 are distributed at intervals along the length direction of the column 2, and the second locking pin 71 engages with the second connecting holes 70.

[0044] Specifically, in this embodiment, the second connecting hole 70 also adopts a gourd-shaped hole with a larger top and a smaller bottom, and the second connecting hole 70 is located on one side of the main body 20, which is separate from the first connecting hole 60 on the two side bends 21, thereby avoiding installation interference between the first crossbeam 1, the second crossbeam 5, and the bearing member 3; the second locking pin 71 at the end of the first crossbeam 1 has the same structure as the first locking pin 61, thereby enabling it to be engaged with the first connecting hole 60 and detachably installed.

[0045] Meanwhile, two rows of second connecting holes 70 are provided on the main body 20. The two rows of second connecting holes 70 are symmetrically arranged, so that when assembling three or more sets of upright components to form multiple rows of shelves, an additional adjacent first beam 1 can be installed on the upright 2, thereby simplifying the structure, reducing the number of upright components, reducing the floor space, and improving installation efficiency.

[0046] Above the pair of first crossbeams 1, a net frame 15 is also provided. A limiting strip is protruding on the first crossbeam 1. The limiting strip forms a stepped structure with the top surface of the first crossbeam 1, so that the two sides of the net frame 15 can be locked onto the first crossbeam 1, thereby improving the placement stability of the net frame 15.

[0047] Furthermore, to facilitate the adjustment of the shelf height during installation, such as... Figure 5 As shown, the shelving structure also includes an assembly 12, and the upper and lower ends of the two uprights 2 can be fixedly connected to each other through the assembly 12 to increase the height of the uprights 2.

[0048] Specifically, the assembly 12 includes a connecting plate 120 and a fixing member 121. The connecting plate 120 is shaped and sized to match the end of the column 2 so as to fit against the outer or inner surface of the column 2. Both the connecting plate 120 and the column 2 are provided with corresponding through holes 123. The fixing member 121 fixes the connecting plate 120 and the column 2 through the through holes 123.

[0049] In this embodiment, the cross-section of the column 2 is U-shaped, therefore, its connecting plate 120 also has a matching shape, which can be inserted into the limiting groove 14 to ensure the stability of the position between the connecting plate 120 and the end of the column 2 and the installation accuracy. During the installation process, first insert one end of the connecting plate 120 into the limiting groove 14, so that the through hole 123 at one end of the connecting plate 120 corresponds to the through hole 123 at the lower end of the column 2. Then, use the fastener 121 to pass through the two columns 2 to fix the column 2 and the connecting plate 120. During this process, the upper end of the connecting plate 120 is exposed to the outside. Finally, insert the upper end of the column 2 into the upper end of the connecting plate 120, and then install the fastener 121 to realize the connection between the two columns 2. The fastener 121 can be a pin or a bolt and nut.

[0050] In this embodiment, the connecting plate 120 is installed in the limiting groove 14 of the two columns 2. On the one hand, this ensures the stability and accuracy of the installation of the connecting plate 120 and reduces the need to adjust the position between the connecting plate 120 and the two through holes 123 on the column 2. On the other hand, by setting the connecting plate 120 in the limiting groove 14, the protruding structure at the connection point of the outer surfaces of the two columns 2 can be avoided from affecting the flatness of the columns 2, thereby preventing the box or container from rubbing against the protruding structure when picking up goods, which would affect the smooth handling of goods.

[0051] This also prevents staff from accidentally scratching or getting injured by these protruding structures.

[0052] Furthermore, to enhance the strength between the two assembled uprights 2, a second crossbeam 5 is fixed at the connection point of the two uprights 2. The through holes 123 of both the uprights 2 and the connecting plate 120 are located on one side of the bend 21. The fastener 121 is a pin, and the end of the second crossbeam 5 has a corresponding insertion hole, coaxial with the through hole 123. The pin is hollow and inserted between the two through holes 123. The second crossbeam 5 is connected to the two uprights 2 by inserting a pin 51 into the pin, thereby improving the connection strength. The hollow design of the pin provides a clear positioning reference for assembly, eliminating the need for additional holes in the connecting plate 120 and the uprights 2. This connection method, where the pin 51 is inserted into the hollow pin, is simple to operate, requires no complex tools, simplifies the assembly process of the uprights 2 and the second crossbeam 5, and improves the assembly efficiency of the shelving.

[0053] In addition, diagonal braces 8 are provided between adjacent columns 2 located in the same column assembly. The diagonal braces 8 have third connecting holes 9 at both ends and fourth connecting holes 10 on the column 2. When the third connecting hole 9 and the fourth connecting hole 10 are in the same position, they can be fixed to each other by connecting piece 11.

[0054] Specifically, in this embodiment, the fourth connecting hole 10 is provided on the main body 20 of the column 2 and is located between a pair of second connecting holes 70. At the same time, there are also several fourth connecting holes 10, which are distributed along the length of the column 2, so that the operator can install the diagonal brace 8 in different positions according to actual needs.

[0055] The two ends of the diagonal brace 8 are fixed between the limiting grooves 14, thus avoiding interference with other components. Therefore, the diagonal brace 8 does not need to be installed in a specific order during installation, improving the smoothness of assembly. The connectors 11 are existing components such as bolts, nuts, or pins. In this embodiment, rivet nuts are used. These connectors 11 can pass through the third connecting hole 9 and the fourth connecting hole 10, thereby effectively improving the strength and stability of the installation.

[0056] Example 2

[0057] like Figures 8-11 As shown, based on Example 1, this example has made some adjustments and improvements to the structure.

[0058] like Figure 8-9 As shown, in this embodiment, the second connecting hole 70 adopts an inverted trapezoidal snap-fit ​​groove structure, and the first locking pins 61 at both ends of the first crossbeam 1 are adapted to the snap-fit ​​groove. The first locking pins 61 and the ends of the first crossbeam 1 are integrally formed. Through the cooperation of the first locking pins 61 and the snap-fit ​​groove, the connection strength between the first crossbeam 1 and the column 2 can be effectively improved. Simultaneously, corresponding holes 16 are provided at the ends of the column 2 and the first crossbeam 1, and an L-shaped pin 17 can be added to fix and limit the connection between the first crossbeam 1 and the column 2.

[0059] Example 3

[0060] Based on Example 1, such as Figure 10 As shown in this embodiment, the column 2 has a convex cross-section, and the connecting plate 120 is also adapted to it. The connecting plate 120 is sleeved on the outer surface of the column 2, and the connecting plate 120 and the column 2 are fixedly connected by bolts and nuts. At the same time, the second crossbeam 5 is also fixed by bolts and nuts.

[0061] Example 4, based on Example 1, such as Figure 11As shown, in this embodiment, the diagonal brace 8 can also be fixedly connected to the column 2 by bolts and nuts; by fixing it with bolts and nuts, the installation angle of the diagonal brace 8 can be adjusted to achieve more installation methods.
