The technical solution includes the following technical features: a connecting tube, a mounting seat, a sleeve, a mounting hole, a reinforcing rib, a supporting foot, a sleeve rod, a foot sleeve, an external thread, a foot hole, an anti-slip pattern, and a rubber pad. In this technical solution, the sleeve rod is a relatively long hollow plastic tube, so the structural strength of the sleeve rod is limited. Among them, in actual use, the sleeve rod is the main load-bearing component, which is easily subjected to a large force. In this way, during use, the sleeve rod is prone to bending, deformation and / or cracking, which seriously affects the service life and safety, thereby increasing the user's maintenance costs. Therefore, it is very necessary to design a high-strength furniture leg to solve the above technical problems. Utility Model Content

[0028] like Figures 1 to 3 As shown, the high-strength furniture leg described in the utility model includes a support tube 1 with an external thread 11 on the outer wall. In order to achieve the purpose of the invention of the utility model, the inner wall of the support tube 1 is provided with a plurality of reinforcing ridges 12 extending along the length direction thereof, and each reinforcing ridge 12 is arranged around the axial center line of the support tube 1, and each reinforcing ridge 12 encloses a molded inner hole 13 in the inner hole of the support tube 1.

[0029] This high-strength furniture leg is constructed by providing a plurality of reinforcing ridges 12 extending along the length of the inner wall of the support tube 1, each ridge 12 being arranged around the axial centerline of the support tube 1. This not only reduces the use of raw materials but also effectively reinforces the support tube 1 at all points around it, significantly improving its structural strength. This significantly enhances the support tube 1's resistance to bending deformation and cracking while controlling manufacturing costs, thereby effectively increasing its service life and safety, and thus helping to reduce user maintenance costs. The reinforcing ridges 12 enclose the inner bore of the support tube 1 to form a molded inner bore 13, which not only facilitates mold manufacturing of the high-strength furniture leg but also reduces the difficulty of mold manufacturing and ensures high mold quality, thus facilitating high-quality production.

[0030] Based on the above structure, the present invention provides five subdivision schemes of the support tube 1. Among them, Figure 4 and Figure 5 The first subdivision scheme is shown; Figure 6 and Figure 7 The second subdivision scheme is shown; Figure 8 and Figure 9 The third subdivision scheme is shown; Figure 10 and Figure 11 The fourth subdivision is shown; Figure 12 and Figure 13 The fifth subdivision is shown.

[0031] like Figure 2 and Figure 3 As shown, each reinforcing rib 12 is integrally formed with the support tube 1. This can further enhance the structural strength of the support tube 1, thereby helping to further enhance the anti-bending deformation and anti-cracking performance, thereby further enhancing the service life and safety.

[0032] The reinforcing ridges 12 and the support tube 1 are formed into an integral structure, which can be easily formed into an integral part by a mold, thereby improving the quality and efficiency of manufacturing.

[0033] like Figure 8 and Figure 9 As shown, the support tube 1 is a tube body with two ends connected, which can facilitate mold forming and demoulding, thereby helping to improve manufacturing convenience.

[0034] like Figure 8 and Figure 9 As shown, a reinforcing convex ring 14 is provided on one of the upper and lower ends of the support tube 1. This can further enhance the structural strength of the support tube 1 while facilitating demoulding, thereby helping to further improve the reliability and applicability of the high-strength furniture leg.

[0035] like Figures 4 to 7 、 Figures 10 to 13 As shown, a reinforcing sheet 15 is provided on one of the upper and lower ends of the support tube 1. This can enhance the structural strength of the end of the support tube 1 while meeting the manufacturing requirements, thereby helping to further improve the reliability and applicability of the high-strength furniture leg.

[0036] like Figure 6 and Figure 7 、 Figure 12 and Figure 13 As shown, the reinforcing sheet 15 is provided with at least one vent hole 151. This facilitates the mold to be removed from the inner hole of the support tube 1 when the support tube 1 and the reinforcing rib 12 are formed using a mold, thereby preventing the support tube 1 from shrinking and deforming or low demolding efficiency, thereby improving manufacturing convenience.

[0037] like Figures 1 to 3 As shown, a grounding convex ring 16 is provided on the lower outer circumferential surface of the support tube 1. This not only improves the structural strength of the lower end of the support tube 1, but also improves the stability and reliability of the support positioning.

[0038] like Figure 2 and Figure 3 As shown, both ends of each reinforcing rib 12 extend to the two ends of the support tube 1, and the reinforcing ribs 12 are arranged in a circular array around the axial centerline of the support tube 1. This ensures that the reinforcing effect of each reinforcing rib 12 on the support tube 1 is more stable and reliable, thereby further improving the reliability and applicability of the high-strength furniture leg.

[0039] like Figure 3 As shown, the surface of each reinforcing rib 12 facing the axial centerline of the support tube 1 is an arcuate convex surface 121. An arcuate transition surface 122 is provided between each adjacent reinforcing rib 12, and both sides of the arcuate transition surface 122 are connected in an arcuate transition manner to the arcuate convex surface 121 on the corresponding two reinforcing ribs 12. This not only makes the reinforcing effect of each reinforcing rib 12 on the support tube 1 more stable and reliable, but also facilitates injection molding and ensures that the quality of the injection molding is very stable and reliable.

[0040] like Figure 3 As shown, the cross section of the reinforcing ridge 12 is fan-shaped, circular, oval, triangular or square. These shapes not only make the reinforcing ridge 12 have a good reinforcing effect, but also facilitate injection molding, thereby ensuring that the high-strength furniture leg has a very high production quality.

[0041] When the cross section of the reinforcing ridge 12 is fan-shaped, the cross section of the reinforcing ridge 12 can be made into a semicircle. This can also facilitate injection molding and ensure that the production quality is very high.

[0042] like Figure 1 and Figure 2 As shown, the high-strength furniture leg further includes a connecting tube 2, which is threadedly sleeved on the external thread 11. This facilitates the lifting and lowering adjustment, thereby better meeting the needs of actual use, which helps to further improve the applicability of the high-strength furniture leg.
