Description

Technical Field

[0001] This utility model relates to connecting components for furniture, specifically a two-section positioning furniture support leg. Background Technology

[0002] A support leg is a device used to adjust the level of furniture. By adjusting the distance between the bottom of the furniture and the ground, the levelness of the furniture can be adjusted after it is placed.

[0003] Chinese patent document CN109008347A discloses a stainless steel structural furniture support leg, which utilizes the meshing connection of a threaded sleeve and a threaded adjusting column to adjust the distance between the base and the furniture bottom plate when the support cover is rotated. However, this furniture support leg has the following two technical defects:

[0004] Firstly, in the aforementioned support leg structure, since the support legs are installed at the bottom of the furniture, adjusting the furniture height requires starting from the bottom, which is very inconvenient. Furthermore, when the support legs are installed on the inner side of the furniture's bottom surface, adjusting them becomes extremely difficult. Secondly, in order not to affect the furniture's height, the overall height of the support legs is relatively small, resulting in a short engagement length for the threaded sleeve and threaded adjusting post, and only a single continuous engagement structure is used. When the supported area is large, uneven force distribution on the support legs on the furniture's bottom board can cause flexural stress in the threaded sleeve and threaded adjusting post. The short, single-stage engagement structure also gives the threaded adjusting post a tendency to tilt under stress, leading to deformation of the support legs after prolonged use. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stable, reliable, and easy-to-use two-stage positioning furniture support leg.

[0006] This utility model provides a two-section positioning furniture support leg, mainly comprising a fixed base, connecting pieces, and a support rod. The fixed base is disposed on the side panel and fixed to the bottom and side surfaces of the side panel respectively. At least two connecting pieces are disposed on the fixed base and arranged vertically. The support rod passes through the connecting pieces and is threadedly connected to the connecting pieces to adjust the distance between the furniture base and the ground when the support rod rotates.

[0007] By optimizing the above structure, the end of the support rod also has a support sleeve. The support sleeve is located on the end of the support rod outside the furniture and is made of soft material to reduce vibration when the furniture comes into contact with the ground.

[0008] By further improving the above structure, an adjustment groove is also provided at the end of the support rod. The adjustment groove is located on the end of the support rod opposite the support sleeve and faces the inside of the furniture, so that the user can adjust the support rod from inside the furniture.

[0009] By optimizing the above structure, a cover is also provided on the mounting base. The cover and the mounting base can accommodate the connecting piece and are fixed together. A buckle is also provided inside the cover, the position of which corresponds to the connecting piece, and the connecting piece has a slot that matches the buckle.

[0010] Further improvements to the above structure include the addition of adjustment holes on the lid. These holes are located on the side of the lid facing inwards from the furniture, allowing the user to easily adjust the adjustment lever.

[0011] The beneficial effects of this two-stage positioning furniture support leg are as follows:

[0012] 1. The support foot of this utility model adopts a structure of double-sided fixing and two-end connection of the support rod. First, the fixing base is fixed on the side and bottom of the side plate, which can realize the vertical and lateral positional stability of the support rod when moving on the fixing base, ensuring that the axis of the support rod will not shift under force, thus improving its stability during adjustment. Second, two connecting pieces are set along the axis of the support rod, which can prevent the axis of the support rod from wobbling radially after being subjected to force, improving the reliability and smoothness of the support rod adjustment.

[0013] 2. In the support leg structure of this utility model, an adjustment groove is provided at the end of the support rod facing the inside of the furniture. This structure allows the user to easily adjust the length of the support rod extending out of the furniture from inside the furniture. In addition to making it easier to adjust the distance between the furniture base and the ground, it also avoids the problem of not being able to adjust the support rod smoothly because the support rod is close to the inside of the base.

The following embodiments are one or more examples of the new technical solutions of the present utility model, which can achieve the corresponding technical effects and solve the corresponding technical problems, and do not mean that the protection scope of the technical solution only includes the following embodiments.

[0023] according to Figures 1 to 7 As shown, the two-section positioning furniture support leg of this utility model mainly consists of a fixed base 2, a connecting piece 22, and a support rod 4. The fixed base 2 is mounted on the side panel 1 and fixed to it. In this utility model, the fixed base 2 has a positioning piece 21, which corresponds to the bottom position of the furniture side panel 1 and is integrally formed with the fixed base 2. The fixed base 2 is fixed to the side and bottom surfaces of the furniture side panel 1 via its side surface and the positioning piece 21, respectively, providing vertical and horizontal positioning on the furniture side panel 1. The fixed base 2 is provided with connecting pieces 22, at least two of which are located on the opposite side where the fixed base 2 connects to the furniture side panel 1 and are arranged vertically. The support rod 4 is inserted into the connecting piece 22, with one end outside the furniture and the other end facing inwards, and is movably connected to the connecting piece 22 by a threaded engagement.
