Description

Technical Field

[0001] This utility model relates to the field of beam technology in shelves or racks, and particularly to a novel beam. Background Technology

[0002] In existing technologies, most crossbeams are designed with a semi-enclosed structure or form a closed cavity directly. However, the closed cavity is made of cuboids or cubes, and the outer perimeter of the closed cavity is directly formed by a planar structure. As a result, when subjected to stress from the support or external impact, the force is directly borne by the plane, leading to stress accumulation and failure to disperse, which affects its service life. Utility Model Content

[0003] The purpose of this invention is to provide a novel crossbeam that divides the enclosed cavity into a support compartment and a connecting compartment, thereby achieving both support and connection functions. Furthermore, it provides bilateral support at the closure point, which increases the force at the closure point and improves the support strength.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A novel crossbeam includes a crossbeam body, wherein the crossbeam body is formed by bending a sheet metal to create a structure with a closed cavity in cross-section;

[0006] The enclosed cavity forms a support compartment and a connecting compartment that are interconnected. The two ends of the plate are bent at the connection point to form the closure of the enclosed cavity. The closure forms a double-sided support part, and an oblique reinforcing rib is provided near the closure.

[0007] Stress-dispersing ribs are provided on the side structures constituting the support compartment and / or the connecting compartment to disperse stress.

[0008] Furthermore, the oblique reinforcing rib is located between the connecting compartment and the closure, and the oblique reinforcing rib forms a force-bearing surface.

[0009] Furthermore, the connecting compartment forms an inverted U-shaped structure, and the closure is located on the side of the inverted U-shaped structure and is positioned close to the support surface on the support compartment.

[0010] Furthermore, the force-bearing surface forms a guide trajectory from the side of the connecting compartment toward the middle of the connecting compartment.

[0011] Furthermore, the inverted U-shaped structure has assembly holes on both sides, and the assembly holes form a double-hole assembly area on the connecting compartment.

[0012] Furthermore, the cross-section of the support cabin is a partially broken triangle, with the two spaced sides of the triangle connected to the inverted U-shaped structure.

[0013] Furthermore, the connections between adjacent sides of the triangle and the connections to the inverted U-shaped structure are all rounded corner transitions.

[0014] Furthermore, the bilateral support portion has an L-shaped structure, which includes a support side and a connecting side, and the support side and / or the connecting side has a double-layer structure.

[0015] Furthermore, in the L-shaped structure, when both the supporting side and the connecting side are double-layered structures or the connecting side is double-layered, the end of the connecting compartment is located at the bottom of the end of the supporting compartment;

[0016] When the support edge is double-layered, the end of the plate constituting the support compartment forms a semi-enclosed cavity, and the end of the plate constituting the connecting compartment is located inside the semi-enclosed cavity.

[0017] Furthermore, the stress-dispersing rib is at least one of a circular arc structure, a constricted cavity structure, or a T-shaped structure, in order to disperse the stress of the novel crossbeam.

[0018] The beneficial effects of this utility model are as follows:

[0019] The novel crossbeam of this utility model divides the enclosed cavity into a support compartment and a connecting compartment, so that it can simultaneously provide support and connection. Furthermore, it achieves bilateral support at the closure point, which increases the force at the closure point and improves the support strength.

[0020] The novel crossbeam of this invention, through the design of a closed cavity and closure points, increases the load-bearing surface of the entire crossbeam in both the horizontal and vertical directions. Simultaneously, the addition of diagonal reinforcing ribs guides the propagation of lateral forces, improving support strength. In terms of appearance, the concealed welding process enhances the aesthetics.

[0021] In this invention, by adding stress-dispersing ribs, the stress on the closed cavity is promptly dispersed to multiple locations, reducing the possibility of stress accumulation and extending the service life of the entire beam. Attached Figure Description

[0033] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0034] Example 1

[0035] See attached document Figure 1-6 As shown, the novel crossbeam in this embodiment includes a crossbeam body 100, which is formed by bending a plate 110 to create a structure with a closed cavity 200 in cross-section. Therefore, the crossbeam in this embodiment can be formed by directly bending the plate, making its production simpler and more convenient. In this embodiment, to achieve the assembly of the crossbeam with other structures and the relative support of the crossbeam, the entire closed cavity can be divided into interconnected support compartments 210 and connecting compartments 220. The two ends of the plate 110 are bent at the connecting points to form the closed portion of the closed cavity 200, and the closed portion forms a double-sided support portion 120. This double-sided support portion 120 increases the strength of the closed portion, and the double-sided support portion can be positioned close to the support surface of the support compartment 210, thereby increasing the overall support strength and improving its practicality.

[0036] In this embodiment, in order to disperse the horizontal force that may be generated at the closure point, an oblique reinforcing rib 500 is provided near the closure point. In use, the oblique reinforcing rib 500 is placed near the closure point to assist in the decomposition of the force at the closure point.

[0037] In this embodiment, to disperse the force on the entire beam during use, stress-dispersing ribs 300 are provided on the side structures of the support compartment 210 and / or the connecting compartment 220. In this embodiment, the stress-dispersing ribs 300 can be provided individually in the support compartment 210 or the connecting compartment 220, or simultaneously in both. Regardless of the arrangement, they will help disperse the force on the outside of the entire enclosed cavity 200. This disperses the localized force within the enclosed cavity 200, and further disperses it through the stress-dispersing ribs, thereby reducing the localized force.

[0038] In this embodiment, compared to a single enclosed cavity, it is not only divided into multiple cavities, each with different functions, giving it more effects; but also a double-layer support is provided at the closure of the enclosed cavity, giving the closure greater strength and assisting in supporting the support chamber.

[0039] In this embodiment, the added stress-dispersing ribs enable the overall structure to disperse stress in a timely manner when subjected to stress, thereby improving its overall strength.

[0040] In this embodiment, the oblique reinforcing rib 500 can be an inclined surface or an arc-shaped structure, located between the connecting compartment 220 and the closing point, thereby forming a force-bearing surface from the connecting compartment to the closing point.

[0041] The novel crossbeam in this embodiment increases the load-bearing surface in both the lateral and vertical directions through the design of enclosed cavities and closure points. Simultaneously, the addition of diagonal reinforcing ribs guides the propagation of lateral forces, improving support strength. In terms of appearance, the concealed welding process between the two layers replaces the traditional exposed welding method, resulting in a more aesthetically pleasing overall structure.

[0042] Example 2

[0043] This embodiment mainly introduces the connecting compartment.

[0044] In this embodiment, the connecting compartment is used to connect the beam to other structures. For example, when forming a shelf or other storage rack, it is necessary to set up columns for height adjustment. In this case, the connecting compartment can be used to connect the beam to different heights of the columns to complete the assembly of single or multiple storage layers.

[0045] Specifically, in this embodiment, the connecting compartment 220 forms an inverted U-shaped structure. Compared with a single-sided structure, the inverted U-shaped structure creates a larger assembly space, which increases the connection space at the assembly point and makes the assembly more secure.

[0046] In this embodiment, the closed section is located on the side of the inverted U-shaped structure and is positioned near the support surface formed above the support compartment 210. At this point, the entire diagonal reinforcing rib is located above the support surface. In actual use, the force-bearing surface forms a guide trajectory extending from the side of the connecting compartment into the middle of the connecting compartment. This trajectory allows the forces generated during the assembly of the connecting compartment with columns, etc., to be promptly dispersed, preventing force accumulation. Preferably, the subsequent assembly position is higher than the diagonal reinforcing rib 500 for better force dissipation.

[0047] In this embodiment, the force-bearing surface guides lateral forces from the inclined direction, enabling the lateral forces to be decomposed and guided, thus avoiding accumulation.

[0048] Specifically, in this embodiment, mounting holes 400 can be provided on both sides of the inverted U-shaped structure. In this case, the mounting holes 400 form a double-hole mounting point on the connecting compartment 220. For example, when assembling with the column by means of a pin, the pin will pass through the mounting holes on both sides of the inverted U-shaped structure. This not only increases the length of the pin extending into the connecting compartment, making the connection more secure, but also increases the number of assembly points compared to single-hole assembly, ensuring the stability of the assembly.

[0049] Example 3

[0050] In this embodiment, the supporting cabin is introduced based on the inverted U-shaped connecting cabin.

[0051] Referring to the accompanying drawings, the cross-section of the support compartment 210 in this embodiment is a partially broken triangle, that is, after it extends, it can be connected with the inverted U-shaped connecting compartment to form a triangle. At this time, the two sides of the triangle are connected to the inverted U-shaped structure respectively. That is, in the triangle, the first side is away from the inverted U-shape, and the second and third sides located on both sides of the first side are connected to the two sides of the inverted U-shaped structure respectively.

[0052] To improve force dispersion, the connections between adjacent sides of the triangle and the inverted U-shaped structure are rounded. This rounded connection effectively decomposes force and avoids creating sharp edges, thus enhancing safety.

[0053] Example 4

[0054] In this embodiment, the product is described in conjunction with the product itself.

[0055] First, the main body of the crossbeam in this embodiment is a hollow structure as a whole. A through cavity is formed inside the hollow structure, and then the through cavity is divided into a connecting compartment and a support compartment along the cross-section.

[0056] Secondly, in order to improve the support strength, based on Embodiment 1, the double-sided support part 120 is preferably an L-shaped structure. In this case, the L-shaped structure forms a semi-enclosed cavity. The L-shaped structure can be configured in various ways, which are described in detail below:

[0057] See attached document Figure 7-9 The L-shaped structure in this embodiment includes a vertical support edge 121 and a horizontal connecting edge 122, wherein the support edge 121 and / or the connecting edge 122 are a double-layer structure.

[0058] In this embodiment, different configurations of the double-layer structure are described in detail below:

[0059] See attached document Figure 7 As shown, when both the support edge 121 and the connecting edge 122 are double-layered structures or the support edge is double-layered, the end of the connecting compartment 220 is located at the bottom of the end of the support compartment 210. At this time, the end of the connecting compartment forms a support to support the end of the support compartment.

[0060] See attached document Figure 8 As shown, when the connecting edge 122 has a double-layer structure, specifically, after the connecting compartment extends and bends downward, the supporting compartment extends and overlaps at the bend, so that the connecting edge 122 forms a double layer, and the overall support strength increases.

[0061] See attached document Figure 9 As shown, when the support edge 121 is double-layered, the end of the plate constituting the support compartment 210 forms a semi-enclosed cavity, and the end of the plate constituting the connecting compartment 220 is located within the semi-enclosed cavity. This is equivalent to providing partial protection for the support edge 121.

[0062] In this embodiment, the stress-dispersing rib 300 is at least one of a circular arc structure, a necked cavity structure, or a T-shaped structure, to disperse the stress of the novel crossbeam. In this embodiment, the stress-dispersing rib is recessed within a closed cavity. Specifically, the various stress-dispersing ribs are described below:

[0063] For the triangular structure, the two sides at the opening of the expansion groove form a triangle connected by points. The side on the same side as the closed cavity is empty. At this time, the triangle faces the inside of the closed cavity and forms a constricted cavity, forming the vertices of the intersecting triangles inside the closed cavity.

[0064] For the T-type, the two sides at the opening of the expansion groove are connected by the edge located in the closed cavity, and the two sides form an angle or arc with the side edge.

[0065] For arc-shaped structures, the two ends of the closed edge are directly connected by the arc that faces the concave part of the closed cavity.

[0066] In this invention, the entire beam body is formed by directly bending the sheet material, which simplifies the processing. To increase the strength after bending, the closed part is fixedly connected by welding to form a relatively strong closed cavity. Then, multiple cavities are formed by bending at the closed cavity, and stress-dispersing ribs are added to disperse the stress on the entire closed cavity, thereby improving the strength.

[0067] In this embodiment, the sheet material can be stainless steel or aluminum, etc. In actual processing, a longer sheet material can be directly bent, then welded and cut to form multiple beam bodies.
