Description

Technical Field

[0001] This utility model relates to the field of sheet metal structural design technology, and in particular to a thin-walled sheet metal L-shaped support plate for the desktop of a height-adjustable desk. Background Technology

[0002] In the structural design of height-adjustable desks, the L-shaped support plate on the desktop is a key structural component connecting the desktop and other parts such as the legs. It is of great significance for ensuring the stability of the desktop installation and the overall structural strength. In practical applications, the thickness of the existing L-shaped support plate is often ≥2.5mm. The thicker plate material significantly increases the amount of raw materials used. In large-scale production, this undoubtedly significantly increases the overall sheet metal cost and puts a lot of cost pressure on enterprises.

[0003] To reduce costs, some attempts have been made to manufacture L-shaped support plates with a thickness of less than or equal to 1.5mm. However, in practical applications, due to the reduced thickness of the plate, its rigidity is insufficient. When subjected to pressure from the desktop or external forces during daily use, it is prone to planar deformation, resulting in gaps between the desktop and the support plate. This affects the flatness and stability of the desktop installation. Furthermore, because the L-shaped structure has unique corner sections, the existing thin-walled designs lack specific anti-outward expansion structures at the L-shaped corners. Under long-term loads, stress concentration at the corners can easily lead to outward deformation, which in turn causes the connection between the support plate and related components to gradually loosen. This reduces the overall reliability of the height-adjustable desk, shortens the product's lifespan, and may also pose safety hazards.

[0004] Furthermore, the installation of ordinary sheet metal support panels relies too heavily on additional accessories for planar positioning, resulting in low installation efficiency. To address this, we propose a thin-walled sheet metal L-shaped support panel for height-adjustable desks. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a thin-walled sheet metal L-shaped support plate for the desktop of a lifting table, which solves the problems of easy twisting and deformation, insufficient structural strength, and inconvenient installation and positioning of existing thin-walled sheet metal L-shaped support plates for lifting tables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A thin-walled sheet metal lift table L-shaped support plate includes a thin-walled base plate, which is bent to have a horizontal mounting end and a vertical connecting end. The horizontal mounting end and the vertical connecting end are provided with reinforcing structures to suppress the torsional deformation of the thin-walled surface.

[0007] Preferably, the reinforcing structure includes ribs, which are provided on the horizontal mounting end or the vertical connection end to increase the strength of the entire surface. By providing ribs at the horizontal mounting end or the vertical connection end, the overall structural strength of the corresponding plate surface can be effectively improved, and its resistance to bending and deformation can be enhanced, thereby better suppressing the torsional deformation of the thin-walled surface under stress and ensuring the structural stability of the support plate during the load-bearing process.

[0008] Preferably, the rib is formed by pressing down the horizontal mounting end or the vertical connecting end. When the rib is provided on the horizontal mounting end, it is formed by pressing down in the direction of the internal area enclosed by the horizontal mounting end and the vertical connecting end. The rib is formed by pressing down, which can achieve integral molding with the thin-walled substrate, simplifying the production process and reducing the manufacturing cost. At the same time, the rib formed by pressing down can significantly increase the moment of inertia of the board surface and enhance the anti-deformation effect.

[0009] Preferably, the ribs are welded to the horizontal mounting end or the vertical connecting end. When the ribs are welded to the horizontal mounting end, they are staggered from the area where the tabletop is installed. By setting the ribs by welding, the strength of specific areas of the board surface can be improved in a targeted manner. This is suitable for scenarios with high strength requirements. Moreover, the welded connection is firm and can effectively transfer stress, thereby enhancing the overall load-bearing capacity of the board surface.

[0010] Preferably, the reinforcing structure further includes concave ribs formed at the bend of the thin-walled substrate to enhance the structural strength of the bend and suppress torsional deformation. By providing concave ribs at the bend of the thin-walled substrate, the stress concentration area at the bend of the L-shaped structure can be specifically reinforced, thereby improving the structural strength of the bend and effectively resisting torsional deformations such as outward expansion and inward contraction caused by stress at the bend, thus ensuring the overall structural stability of the L-shaped support plate.

[0011] Preferably, the concave rib is formed by pressing the inside of the bend of the thin-walled substrate. The concave rib is formed by pressing the inside area enclosed by the bend of the thin-walled substrate towards the horizontal mounting end and the vertical connection end. The concave rib is formed by pressing the inside from the bend, which can make full use of the substrate material itself without increasing the additional material cost. At the same time, it can optimize the stress distribution at the bend, reduce stress concentration, significantly enhance the torsional resistance at the bend, and further suppress torsional deformation.

[0012] Preferably, the thin-walled substrate is provided with protrusions that are interference-fitted with the column to form a positioning point. The interference fit between the protrusions and the column can achieve preliminary positioning without relying on additional positioning accessories, which simplifies the installation process and improves installation efficiency.

[0013] Preferably, the thin-walled substrate is provided with assembly screw holes for fixed connection with other components. The assembly screw holes provide a reliable interface for the fixed connection of the support plate with other components, and the fixed connection is made by screws or other connectors passing through the screw holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses a thin-walled substrate, which significantly reduces material costs and achieves lightweight design. The ribs are reinforced by denting or welding to enhance the strength of the board surface. The concave ribs optimize the stress distribution at bends, significantly improving resistance to torsional deformation and ensuring structural stability. The protrusions can be precisely positioned with the column through an interference fit, eliminating the need for additional accessories and improving installation efficiency. This solves the problems of easy deformation and low installation efficiency of thin-walled components, balancing lightweight, high strength, and ease of installation, and extending the service life of the lifting table.

Example

[0022] Please see Figure 1-2 A thin-walled sheet metal lifting table L-shaped support plate includes a thin-walled base plate 1, which is bent to have a horizontal mounting end 11 and a vertical connecting end 12. The horizontal mounting end 11 and the vertical connecting end 12 are provided with a reinforcing structure 2 for suppressing the torsional deformation of the thin-walled surface.

[0023] Furthermore, the reinforcing structure 2 includes ribs 21, which are provided on the horizontal mounting end 11 or the vertical connecting end 12 to increase the strength of the entire surface. The ribs 21 are formed by pressing the horizontal mounting end 11 or the vertical connecting end 12 inward. When the ribs 21 are provided on the horizontal mounting end 11, they are pressed inward toward the inner area enclosed by the horizontal mounting end 11 and the vertical connecting end 12, so that the pressed ribs 21 do not protrude outward, which can prevent the tabletop from affecting the flat connection with the tabletop during installation. When the ribs 21 are provided on the horizontal mounting end 11, they are pressed inward toward the outer area enclosed by the horizontal mounting end 11 and the vertical connecting end 12. The concave ribs 21 can be directly pressed out on the corresponding surface by stamping or other processes. This method is integrally formed with the thin-walled substrate 1, which can ensure the connection strength between the ribs 21 and the mounting surface, and the production process is simple.

[0024] Its reinforcing structure 2 also includes a concave rib 22, which is formed at the bend of the thin-walled substrate 1 to enhance the structural strength of the bend of the thin-walled substrate 1 and suppress torsional deformation. The concave rib 22 is formed by pressing the bend of the thin-walled substrate 1 into the inner area enclosed by the horizontal mounting end 11 and the vertical connecting end 12. The concave rib 22 is formed by pressing the bend of the thin-walled substrate 1 into the inner area. The thin-walled substrate 1 is provided with a protrusion 3 that is interference-fitted with the column to form a positioning point. The thin-walled substrate 1 is provided with an assembly screw hole 4 for fixed connection with other components.

[0025] Its thin-walled substrate 1 serves as the main structure of the support plate. It is made of thin-walled sheet metal and can be bent to form mutually perpendicular horizontal mounting ends 11 and vertical connecting ends 12. This L-shaped structure design can adapt to the connection requirements between the desktop and the column of the height-adjustable table, and achieve stable support for the desktop. The thickness of its thin-walled substrate 1 can be selected according to the actual strength requirements, and can be ≤1.2mm. The thin-walled design can reduce material costs and reduce the overall weight of the height-adjustable table.

[0026] The reinforcing structure 2 is set on the horizontal mounting end 11 and the vertical connecting end 12. Its core function is to suppress the torsional deformation of the thin-walled surface and improve the structural strength of the entire support plate. The reinforcing structure 2 is composed of ribs 21 and concave ribs 22. The ribs 21 can be set on the horizontal mounting end 11 or the vertical connecting end 12. The concave ribs 22 are formed at the bend of the thin-walled substrate 1 to enhance the structural strength of the bend and suppress torsional deformation. The concave ribs 22 are formed by pressing the concave structure inside the bend of the thin-walled substrate 1. By pressing out the concave structure on the inside of the bend, the stress distribution at the bend is changed and the deformation resistance of the bend is improved. The shape of the concave can be arc-shaped, right-angled, etc.

[0027] The protrusions 3 on the thin-walled substrate 1 can be positioned by interference fit with the column. The shape of the protrusions 3 can be hemispherical, cylindrical, etc. When the support plate and the column are installed, the protrusions 3 can be embedded in the corresponding position of the column. The interference fit achieves positioning and anti-slip, which facilitates subsequent fixing and connection operations and improves installation efficiency.

[0028] The assembly screw hole 4 opened on the thin-walled substrate 1 can be used to fix and connect with other components. By passing screws through the assembly screw hole 4, the corresponding components can be fixedly connected to the thin-walled substrate 1.

[0029] The thin-walled substrate 1 is made of steel plate with a thickness of ≤1.2mm. It is bent to form a horizontal mounting end 11 and a vertical connecting end 12. Ribs 21 and concave ribs 22 are provided on the thin-walled substrate 1. The ribs 21 are formed by pressing the vertical connecting end 12 inwards, and the concave ribs 22 are formed by pressing the interior of the bent portion of the thin-walled substrate 1 in an arc shape. Two diagonally arranged hemispherical protrusions 3 are provided on the thin-walled substrate 1 for interference fit positioning with the column. Simultaneously, assembly screw holes 4 are provided on the horizontal mounting end 11 and the vertical connecting end 12 for fixed connection with components such as the tabletop and the column. During use, when the thin-walled substrate 1 is subjected to pressure or tension perpendicular to its surface, the thin-walled substrate 1 is prone to bending deformation. The ribs 21, by forming protruding or concave strip structures on the board surface, can transform the originally flat board surface into a beam-like load-bearing structure. This structure can distribute external forces over a larger area, thereby reducing unit stress. The ribs 21 formed by the indentation change the cross-sectional shape of the plate surface. Compared with a flat plate surface, its moment of inertia is significantly increased, and its bending resistance is naturally improved. It can effectively resist bending deformations such as upturning and collapsing of the plate surface, thereby increasing the overall surface strength. The concave ribs 22 are formed by the indentation inside the bending part of the thin-walled substrate 1. This structure improves the moment of inertia and torsional section modulus of the bending part by changing the material distribution and cross-sectional shape of the bending part. When the bending part is subjected to a force that causes outward expansion or inward contraction, the concave ribs 22 can effectively resist this deformation trend, disperse stress, and avoid stress concentration at a certain point, thereby enhancing the structural strength of the bending part and suppressing torsional deformation. In addition, the presence of the concave ribs 22 can also restrict the free deformation of the material at the bending part, making it more difficult for the material to displace under stress, further improving the overall stability of the L-shaped structure and ensuring the structural reliability of the support plate during long-term use. Example

[0030] The rib 21 is welded to the horizontal mounting end 11 or the vertical connecting end 12. When the rib 21 is welded to the horizontal mounting end 11, it is staggered from the area where the table is installed. When the strength of the rib 21 is required to be higher, the separately made rib 21 can be fixed to the horizontal mounting end 11 or the vertical connecting end 12 by welding. The welding material can be the same as or compatible with the thin-walled substrate 1. The welding method can be arc welding, laser welding, etc., to ensure that the welding is firm and to avoid falling off during use.

[0031] The thin-walled substrate 1 is made of steel plate with a thickness of ≤1.2mm, bent to form a horizontal mounting end 11 and a vertical connecting end 12. The ribs 21 in the reinforcing structure 2 are welded to the horizontal mounting end 11 or the vertical connecting end 12. The welding material is the same steel as the substrate, and laser welding is used. The concave ribs 22 are formed by pressing the inside of the bent part of the thin-walled substrate 1 and are right-angled. A cylindrical protrusion 3 is provided on the thin-walled substrate 1 for positioning with the column. The horizontal mounting end 11 and the vertical connecting end 12 are respectively provided with assembly screw holes 4. When the ribs 21 are welded to the horizontal mounting end 11 or the vertical connecting end 12, the separately made ribs 21 have a certain strength and rigidity. After welding, they can form an integral load-bearing structure with the board surface. The connection strength at the weld ensures that the ribs 21 can work together with the board surface. When external force is applied, the ribs 21 can share part of the force, reduce the load on the board surface, and thus enhance the strength of the entire surface.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
