[0002] A cross-beam shelf is a professional warehouse shelf for storing pallet goods. It mainly consists of cross-beams, cross-members and U-shaped parts. A plurality of cross-members are arranged between two cross-beams, and the cross-members are perpendicular to the cross-beams. Both ends of the cross-members are connected to the cross-beams through U-shaped parts to form a shelf unit. In order to ensure the stability and safety of the shelf and prevent the goods or lifting tools from exceeding the safe range, a limiting strip is often arranged between two relatively arranged cross-beams. However, the current limiting strip is fixed to the cross-beam by using rivets and bolts. Such a fixing method is very troublesome during installation or disassembly, greatly reducing the installation and disassembly efficiency. Summary of the Utility Model

[0015] In a possible implementation manner, a bayonet is further provided on the limiting plate. The bayonet is located below the opening and is aligned with the opening, and one end of the bayonet extends downward to the lower end of the limiting plate.

[0016] In a possible implementation manner, one of the limiting plates is perpendicular to the substrate, and the other limiting plate is not perpendicular to the substrate, and an angle less than 10° is formed between the two limiting plates.

[0017] In a possible implementation manner, the angle is between 4° and 6°.

[0018] In a possible implementation manner, the two sides of the end of the limiting strip close to the cross beam are bent to form flanges extending in the second direction.

Therefore, it should not be construed as a limitation to the present utility model.

[0036] It should also be noted that, unless otherwise clearly specified and defined, terms such as "installation", "connection", "coupling", "fixation", "setting", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located above the other element, or there may also be one or more intermediate elements. Terms such as "first", "second", "third", etc. are only for the convenience of describing the present technical solution and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second", "third", etc. may explicitly or implicitly include one or more of such features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation in order to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0038] In the prior art, the fixing method of the limiting strip of the shelf is by bolt connection. For example Figure 1As shown, a first mounting hole and a second mounting hole are respectively formed in the U-shaped connecting member 30' and the limiting strip 20. Then, the U-shaped connecting member 30' is fixed to the cross beam 10 by bolts. After that, the limiting strip 20 is placed on the U-shaped connecting member 30' such that the first mounting hole and the second mounting hole are aligned. Then, rivets are sequentially passed through the second mounting hole and the first mounting hole to fix the limiting strip 20 to the U-shaped connecting member 30', thereby realizing the fixed installation of the limiting strip 20 between the two cross beams 10. However, the installation or disassembly using such a connection structure is relatively cumbersome, greatly reducing the installation and disassembly efficiency. In addition, a current shelf has up to twenty or more layers, and a limiting strip needs to be provided for each layer. If the above-mentioned connection structure is adopted, it will not only increase the labor intensity of workers but also pose a certain danger due to working on a high-level shelf. For this reason, the present application provides a connection structure 100 for a shelf, which has a simple structure, is convenient for assembly, can reduce the pulling intensity of workers, and improve the installation and disassembly efficiency.

[0039] Please refer to Figures 2 to 7 , the present application provides a connection structure 100 for a shelf. The connection structure 10 of the shelf includes a limiting strip 20, a plurality of buckles 30, and at least two cross beams 10.

[0040] Specifically, at least two cross beams 10 are symmetrically distributed at intervals in the first direction X. An installation area is defined between the two outermost cross beams 10. The limiting strip 20 spans across the installation area. A plurality of buckles 30 are installed at intervals along the first direction X on the limiting strip 20. A slot 11 is provided on the cross beam 10. In the assembled state, the buckle 30 is inserted into the corresponding slot 11 to connect the limiting strip 20 to the cross beam 10.

[0041] Here, it should be noted that the above-mentioned "first direction X" refers to the width direction of the cross beam 10, and specifically can refer to Figure 2 the X direction in

[0042] Optionally, the connection manner between the buckle 30 and the limiting strip 20 may include but is not limited to welding, clamping, bolt connection, etc., as long as the buckle 30 can be fixedly connected to the limiting strip 20.

[0043] Exemplarily, at least two crossbeams 10 means two or more than two. The specific quantity needs to be determined according to the specific load-bearing requirements of the shelf design and the usage environment, etc., to ensure the safety and stability of the shelf. In addition, it should be noted that the buckle 30 is used to fix to the crossbeam 10, and the quantity of the buckle 30 adopted needs to be determined according to the quantity of the crossbeam 10. For example: if there are two crossbeams 10, then two buckles 30 need to be installed at intervals on the limiting strip 20, so as to respectively snap the two buckles 30 into the corresponding card slots 11 of the two crossbeams 10 to realize the fixed connection between the limiting strip 20 and the crossbeam 10; if there are three crossbeams 10, then three buckles 30 need to be installed at intervals on the limiting strip 20, so as to respectively snap the three buckles 30 into the corresponding card slots 11 of the three crossbeams 10 to realize the fixed connection between the limiting strip 20 and the crossbeam 10.

[0044] Taking the setting of two crossbeams 10 as an example for illustration, that is, the two crossbeams 10 are arranged at intervals along the first direction X to form an installation area between the two crossbeams 10. Then, the limiting strip 20 is spanned across the installation area, and the two buckles 30 installed on the limiting strip 20 are respectively snapped into the card slots 11 opened on the two crossbeams 10, so as to realize the fixed connection between the limiting strip 20 and the crossbeam 10. The structure is simple and can be disassembled and assembled quickly.

[0045] It can be seen from this that the connection structure of the shelf of the present application fixes the buckle 30 on the limiting strip 20 and opens the corresponding card slot 11 on the crossbeam 10, so that when connecting the limiting strip 20 and the crossbeam 10, the buckle 30 and the card slot 11 are aligned, and the buckle 30 is pressed to be embedded into the card slot 11 for fixation, so as to realize fixing the limiting strip 20 on the crossbeam 10. Compared with the traditional bolt connection method, the connection is simple, the assembly is convenient, the pulling strength of the workers can be reduced, and the installation and disassembly efficiency can be improved.

[0046] In a possible implementation manner, the buckle 30 includes a substrate 31 fixedly connected to the limiting strip 20, and two limiting plates 32 are formed by bending the two sides of the substrate 31 downward. The card slot 11 includes two card slots 11 arranged at intervals. The card slot 11 includes a first slot opening 11a and a second slot opening 11b that are communicated with each other. The first slot opening 11a is opened on the opposite surfaces of the crossbeam 10 in the first direction X, and the second slot opening 11b is opened on the top surface of the crossbeam 10. Among them, in the assembled state, at least part of the limiting plate 32 is embedded into the corresponding first slot opening 11a and second slot opening 11b for fixation.

[0047] Exemplarily, when fixing the limit strip 20, the buckle 30 fixed on the limit strip 20 is aligned with the slot 11. At this time, the two limit plates 32 of the buckle 30 are respectively located above the two slots 11 and are in an aligned state. Then, the limit strip 20 is pressed downward so that the limit plate 32 is embedded in the first slot 11a and the second slot 11b from the top for fixation, thereby realizing the fast fixation of the limit strip 20 to the beam 10; when the limit strip 20 needs to be disassembled, it is only necessary to detach the limit plate 32 from the first slot 11a and the second slot 11b to realize the disassembly of the limit strip 20. The structure is simple and the disassembly and assembly are convenient.

[0048] In a possible implementation, the spacing between the two slots 11 is equal to the distance between the two limiting plates 32, and the width of the slot 11 is greater than the thickness of the limiting plates 32. In other words, when the limiting strip 20 is fixed to the crossbeam 10, the two limiting plates 32 of the buckle 30 need to be aligned with the two slots 11. To this end, it is necessary to ensure that the spacing between the two slots 11 is equal to the distance between the two limiting plates 32, so that the two limiting plates 32 can be correspondingly embedded in the corresponding slots 11, avoiding the problem of being unable to achieve quick connection due to mismatched sizes.

[0049] In a possible implementation, the inner wall of the first notch 11a has a protrusion 40 extending outward, and the limiting plate 32 is provided with an opening 32a adapted to the protrusion 40. In this way, when the limiting plate 32 is inserted into the first notch 11a, the surface of the limiting plate 32 will abut against the protrusion 40. As the limiting plate 32 is continuously inserted, when the opening 32a on the limiting plate 32 slides down to a position aligned with the protrusion 40, the protrusion 40 is inserted into the opening 32a to prevent shaking or escaping from the slot 11, thereby ensuring a firm connection of the limiting strip 20.

[0050] In a possible implementation, the limiting plate 32 is further provided with a bayonet 32b, which is located below the opening 32a and aligned with the opening 32a, and one end of the bayonet 32b extends downward to the lower end of the limiting plate 32. In this way, when the limiting plate 32 is inserted into the slot 11, the bayonet 32b will be clamped with the bottom of the first slot 11, thereby fixing the limiting plate 32 in the slot 11, further ensuring the firm connection of the limiting strip 20.

[0051] In a possible implementation, one limiting plate 32 is perpendicular to the substrate 31, and the other limiting plate 32 is not perpendicular to the substrate 31, and an angle less than 10° is formed between the two limiting plates 32. Among them, the angle is between 4° and 6°. In this way, when assembling the buckle 30 with the card slot 11, press the two limiting plates 32 inward so that an elastic force can be formed between the two limiting plates 32 to snap into the card slot 11. After the two limiting plates 32 are snapped into the card slot 11, the two limiting plates 32 expand outward due to the absence of extrusion force, and then abut against the inner wall of the cross beam 10, which can prevent the limiting plates 32 from shaking or disengaging from the card slot 11, thus ensuring the firm connection of the limiting strip 20.

[0052] In a possible implementation, on both sides of one end of the limiting strip 20 close to the cross beam 10, there are bent edges 20a extending along the second direction Y. The bent edges 20a are flush with the surface of the limiting strip 20 close to the cross beam 10 and jointly form a connecting surface, and the surface of the substrate 31 facing away from the cross beam 10 is welded to the connecting surface.

[0053] The present application also provides a shelf, which includes the connection structure 100 disclosed in the above embodiment and a plurality of cross beams (not shown). The plurality of cross beams are arranged across the installation area of the connection structure and are fixedly connected to the cross beam 10. Therefore, this shelf also has all the above technical effects, which will not be elaborated here one by one.

[0054] It can be understood that the above embodiments only represent the preferred implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention shall fall within the scope covered by the claims of the present invention.
