Description

Technical Field

[0001] This utility model relates to the field of furniture accessories technology, and in particular to a support leg structure. Background Technology

[0002] Traditional support legs are usually made of solid metal or wood. While they have a certain degree of strength and stability, they also have the following disadvantages: 1. Solid support legs are heavy, making it difficult to move furniture or equipment; 2. Solid metal or wood materials are expensive, increasing the overall cost of the product; 3. Traditional support legs are prone to deformation or breakage under high stress, affecting their service life.

[0003] To overcome the aforementioned shortcomings, some existing technologies have developed support leg structures made of hollow tubing. These structures typically enhance the strength of the support legs by incorporating reinforcing ribs. However, these structures still suffer from the following deficiencies: 1. Insufficient connection strength: The connection between the reinforcing ribs and the hollow tubing is relatively simple and cannot effectively resist stress from all directions, making the connection prone to breakage; 2. This structure requires additional connectors to attach the support legs to furniture or equipment, making the installation process cumbersome.

[0004] Therefore, there is an urgent need in this field for a support leg structure that is lightweight, low-cost, highly stress-resistant, and easy to install.

[0005] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a support foot structure that is lightweight, low-cost, strong in stress resistance, and easy to install.

[0007] This utility model is achieved through the following technical solution:

[0008] A support leg structure includes a hollow tube and a connecting column disposed inside the hollow tube. A plurality of connecting plates are provided between the connecting column and the hollow tube to connect the two. A reinforcing plate is provided between the connecting plate and the hollow tube to connect the upper end of each connecting plate to the upper end of the hollow tube to form a whole, thereby improving the stress resistance. The upper end of the connecting column is also provided with a stud extending from the upper surface of the reinforcing plate.

[0009] As described above, in a support foot structure, a partition cavity is provided between adjacent connecting plates, and a through hole is provided on the reinforcing plate at the position corresponding to the partition cavity.

[0010] As described above, in a support foot structure, the lower end of the hollow tube is provided with an extension tube, and the inner wall of the extension tube is provided with several protrusions. The protrusions, the connecting plate, and the connecting column together form an installation groove.

[0011] As described above, in one type of support foot structure, a bottom cover is connected within the mounting groove.

[0012] As described above, in a support foot structure, the bottom cover includes a bottom plate and a connecting ring having an upper part on the bottom plate, the connecting ring being interference-fitted with a protrusion.

[0013] In the support leg structure described above, a first reinforcing rib is provided on the inner sidewall of the connecting ring.

[0014] As described above, in a support leg structure, the hollow tube is further provided with a second reinforcing rib extending into the partition cavity.

[0015] In one type of support leg structure as described above, the lower end of the connecting post is provided in a threaded hole that can be threaded with the stud of another support leg structure.

[0016] As described above, in one type of support foot structure, a cushioning pad is connected to the lower end face of the bottom cover.

[0017] As described above, the hollow tube, connecting column, connecting plate, and reinforcing plate are an integral structure.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention significantly improves the overall strength and stress resistance of the support leg structure by setting a connecting plate between the connecting column and the hollow tube, and a reinforcing plate between the connecting plate and the hollow tube, connecting the upper end of the connecting plate and the upper end of the hollow tube into a whole. This effectively resists stress from all directions, avoids deformation or breakage caused by uneven stress, and extends the service life of the support leg. Using a hollow tube as the main support structure greatly reduces the overall weight compared to traditional solid support legs. This makes the support leg easy to move and transport when used in furniture, equipment, etc., reducing the labor intensity of users. The hollow tube, connecting plate, and reinforcing plate have a simple structure, are easy to manufacture, and reduce production costs. The upper end of the connecting column has studs extending from the upper surface of the reinforcing plate, which can be directly connected to furniture, equipment, and other objects requiring support without additional connectors or complicated installation steps, simplifying the installation process. Furthermore, this structure is suitable for various occasions, such as furniture, machinery, and display racks, and has wide applicability. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 7 The support leg structure shown includes a hollow tube 1 and a connecting post 2 disposed inside the hollow tube 1. A plurality of connecting plates 3 are provided between the connecting post 2 and the hollow tube 1 to connect the two. A reinforcing plate 4 is provided between the connecting plate 3 and the hollow tube 1 to connect the upper end of each connecting plate 3 to the upper end of the hollow tube 1 to form a whole, thereby improving the stress resistance. The upper end of the connecting post 2 is also provided with a stud 5 extending from the upper surface of the reinforcing plate 4.

[0030] This invention significantly improves the overall strength and stress resistance of the support leg structure by setting a connecting plate 3 between the connecting column 2 and the hollow tube 1, and a reinforcing plate 4 between the connecting plate 3 and the hollow tube 1, connecting the upper end of the connecting plate 3 and the upper end of the hollow tube 1 into a whole. This effectively resists stress from all directions, avoids deformation or breakage caused by uneven stress, and extends the service life of the support leg. Using the hollow tube 1 as the main support structure greatly reduces the overall weight compared to traditional solid support legs. This makes the support leg easy to move and transport when used in furniture, equipment, etc., reducing the labor intensity of users. The hollow tube 1, connecting plate 3, and reinforcing plate 4 have a simple structure, are easy to manufacture, and reduce production costs. The upper end of the connecting column 2 has a stud 5 extending from the upper surface of the reinforcing plate 4, which can be directly connected to furniture, equipment, and other objects requiring support without additional connectors or complex installation steps, simplifying the installation process. Furthermore, this structure is suitable for various occasions, such as furniture, machinery, and display racks, and has wide applicability.

[0031] Furthermore, a partition cavity 6 is provided between adjacent connecting plates 3, and a through hole 41 is provided on the reinforcing plate 4 at the position corresponding to the partition cavity 6. The partition cavity 6 rationally divides the space between the connecting plates 3, making the stress distribution more uniform and avoiding local deformation or fracture caused by stress concentration. At the same time, the design of the through hole 41 enhances the connection strength between the reinforcing plate 4 and the connecting plate 3, further improving the stress resistance of the overall structure. The design of the partition cavity 6 and the through hole 41 reduces the use of materials and lowers production costs while ensuring structural strength, and improves the material utilization rate, which is in line with the design concept of lightweight and resource conservation. The cooperative design of the partition cavity 6 and the through hole 41 allows the support leg structure to better disperse stress when subjected to external forces, avoiding deformation or damage caused by excessive local stress, thereby improving the overall stability and service life of the structure.

[0032] In one embodiment, the lower end of the hollow tube 1 is provided with an extension tube 11. The inner wall of the extension tube 11 is provided with several protrusions 111. The protrusions 111, the connecting plate 3, and the connecting column 2 together form an installation groove 7. A bottom cover 8 is connected within the installation groove 7, thereby improving the stability and anti-overturning ability of the support foot, especially suitable for scenarios requiring large loads or located on uneven ground. The installation groove 7 formed by the protrusions 111, the connecting plate 3, and the connecting column 2 forms a stable connection structure, allowing the bottom cover 8 to be firmly installed at the bottom of the support foot, avoiding the problem of unstable bottom connections in traditional support feet, and further enhancing the overall structural strength and durability. The design of the installation groove 7 allows the bottom cover 8 to be easily installed and removed, facilitating users to replace it with different materials or functions according to actual needs, such as anti-slip bottom covers, shock-absorbing bottom covers, etc., improving the product's flexibility and applicability. The design of the protrusions 111 and the installation groove 7 makes the stress distribution at the bottom of the support foot more uniform, avoiding deformation or damage caused by localized stress concentration, further improving the stress resistance and durability of the support foot. The bottom cover 8 can serve as a buffer layer between the support foot and the ground, reducing direct friction between the bottom of the support foot and the ground, reducing wear, and extending the service life of the support foot.

[0033] Furthermore, the bottom cover 8 includes a base plate 81 and a connecting ring 82 on the upper part of the base plate 81, wherein the connecting ring 82 is press-fitted with the protrusion 111. This eliminates the need for additional accessories for connection, facilitating the assembly and disassembly of the bottom cover 8.

[0034] Furthermore, a first reinforcing rib 821 is provided on the inner sidewall of the connecting ring 82, thereby further enhancing the stress resistance of the bottom cover 8. The bottom plate 81, the connecting ring 82, and the first reinforcing rib 821 are an integral structure.

[0035] In one embodiment, a buffer pad 80 is connected to the lower end face of the bottom cover 8, thereby reducing the damage of the support foot to the ground. The buffer pad 80 can be a flexible material such as felt, sponge or soft rubber, and the buffer pad 80 can be connected to the bottom cover 8 by glue or other connection methods.

[0036] In one embodiment, the lower end of the connecting post 2 is provided with a screw hole 20 that can be threaded into the stud 5 of another support leg structure. The overall length can be adjusted by connecting two or more support leg structures together.

[0037] In one embodiment, the inner wall of the hollow tube 1 is further provided with a second reinforcing rib 12 that extends into the partition cavity 6, thereby further enhancing the stress resistance of the hollow tube 1.

[0038] In one embodiment, the hollow tube 1, connecting column 2, connecting plate 3, and reinforcing plate 4 are integrated into a single structure. This integrated structure eliminates potential weak points in traditional multi-component connections, making the overall support leg structure more stable and better able to resist stress from all directions, significantly improving its resistance to deformation and fracture. The integrated structure reduces the number of parts and assembly steps, simplifying the manufacturing process, lowering production costs, and reducing quality problems caused by assembly errors, thus improving product consistency and reliability. The integrated structure also makes the support leg appear simpler and smoother, avoiding protrusions, gaps, or irregular surfaces that may occur in traditional multi-component connections, enhancing the overall aesthetics of the product.

[0039] In one embodiment, the hollow tube 1 is cylindrical. The cylindrical structure has symmetry, which can evenly distribute stress from all directions, avoid local deformation or fracture caused by stress concentration, and thus improve the overall strength and durability of the support leg.

[0040] In one embodiment, the stud 5 is made of metal and is injection molded integrally with the connecting post 2. The metal stud 5 possesses high mechanical strength and wear resistance, capable of withstanding significant tensile and torque forces, ensuring a more secure and reliable connection between the support leg and the furniture or equipment. The integral injection molding of the stud 5 and connecting post 2 eliminates the need for additional connectors or assembly steps, making the installation of the support leg simpler and faster, thus improving installation efficiency. The integrated structure avoids the loosening problems that may occur in traditional threaded connections, ensuring a consistently stable connection between the stud 5 and connecting post 2, reducing the need for later maintenance and adjustments. After the metal stud 5 and connecting post 2 are injection molded integrally, stress can be more evenly distributed throughout the entire support leg structure, preventing deformation or damage caused by localized stress concentration and improving the overall structure's stress resistance.
