[0041] Example 1
[0042] Please refer to Figures 1 to 6 This utility model embodiment provides a support foot 100, including: a first support member 1, a second support member 2, a third support member 3, a plug-in adjustment structure 4, and a threaded adjustment structure 5.
[0043] The first support member 1, the second support member 2, and the third support member 3 are coaxially arranged from top to bottom. The upper end of the first support member 1 is used for detachable connection with the furniture frame (not shown in the figure). Specifically, the upper end of the first support member 1 can be detachably connected to the furniture frame through threaded connection, snap-fit connection, plug-in connection, or fasteners, etc., without specific limitations. The first support member 1, the second support member 2, and the third support member 3 are all cylindrical structures. Of course, in some other embodiments, the first support member 1, the second support member 2, and the third support member 3 can also be column structures, without specific limitations.
[0044] The first support member 1 and the second support member 2 are connected by a plug-in adjustment structure 4 for adjusting the length of the support foot 100 with a large stroke; the second support member 2 and the third support member 3 are connected by a threaded adjustment structure 5 for fine-tuning the length of the support foot 100.
[0045] In this way, the support leg 100 can not only quickly adjust its overall length, but also perform high-precision fine-tuning, thus achieving rapid adjustment of the furniture's height relative to the ground, as well as fine-tuning to ensure the furniture does not wobble. It possesses the advantages of both rapid height adjustment with a large range and fine-tuning capabilities.
[0046] Alternatively, please refer to Figures 4 to 6 In this embodiment, the plug-in adjustment structure 4 includes four sets of height adjustment slots 41 and four height adjustment protrusions 42. The four sets of height adjustment slots 41 are evenly spaced circumferentially at the lower end of the first support member 1, and each set has seven height adjustment slots 411 of different lengths. The four height adjustment protrusions 42 are evenly spaced circumferentially at the upper end of the second support member 2. Thus, by inserting the four height adjustment protrusions 42 into the different length height adjustment slots 411 of the four sets of height adjustment slots 41, a large stroke adjustment of the support leg 100 length can be quickly achieved. Of course, in other embodiments, the number of height adjustment slots 41 and height adjustment protrusions 42 can also be two, three, five, or more sets; no specific limitation is made here. Each set of height adjustment slots 41 can also have three, four, five, six, eight, or more height adjustment slots 411 of different lengths. Understandably, several sets of height adjustment slots 41 can also be evenly spaced along the circumference on the upper end of the second support member 2, while height adjustment protrusions 42, in the same number as the sets of height adjustment slots 41, can be evenly spaced along the circumference on the lower end of the first support member 1. No specific restrictions are imposed here.
[0047] Alternatively, please refer to Figure 6 In this embodiment, multiple height adjustment slots 411 in the height adjustment slot group 41 are arranged circumferentially at intervals from shortest to longest; the lengths of each height adjustment protrusion 42 are all equal. This makes it easy to find the required height adjustment slot 411 for height adjustment.
[0048] Alternatively, please refer to Figure 6 In this embodiment, the first support member 1 is cylindrical; several sets of height adjustment grooves 41 are evenly spaced along the circumference on the lower inner wall of the first support member 1; and height adjustment protrusions 42 are evenly spaced along the circumference on the upper outer peripheral wall of the second support member 2. Of course, in other embodiments, several sets of height adjustment grooves 41 are evenly spaced along the circumference on the lower outer periphery of the first support member 1; the upper end of the second support member 2 is cylindrical, and the height adjustment protrusions 42 are evenly spaced along the circumference on the inner peripheral wall of the upper end of the second support member 2.
[0049] To ensure a more secure connection between the first support member 1 and the second support member 2, optionally, please refer to... Figure 5 and Figure 6In this embodiment, a protruding elastic buckle 21 is provided on the outer peripheral wall of the upper end of the second support member 2, which is used to lock the first support member 1 and the second support member 2 onto the inner peripheral wall of the first support member 1 when they are inserted together. In this way, the elastic buckle 21 engages with the inner peripheral wall of the first support member 1, which increases the friction between the first support member 1 and the second support member 2, thus making the insertion and engagement of the first support member 1 and the second support member 2 more secure.
[0050] To visually demonstrate the height adjustment between the first support member 1 and the second support member 2, optionally, please refer to... Figure 3 and Figure 5 In this embodiment, a first adjustment mark 22 is vertically provided on the outer periphery of the second support member 2. Specifically, the first adjustment mark 22 is a large stroke adjustment mark, including numerical value and scale mark, and the smallest scale unit in the first adjustment mark 22 represents 5 millimeters.
[0051] Alternatively, please refer to Figure 5 and Figure 6 In this embodiment, the threaded adjustment structure 5 includes a molded nut 51 and a cooperating screw 52. The molded nut 51 is disposed at the lower end of the second support member 2, and the screw 52 is disposed at the upper end of the third support member 3. Thus, the length of the support leg 100 can be finely adjusted through the threaded engagement of the molded nut 51 and the screw 52. Specifically, in this embodiment, the lower end of the second support member 2 and the third support member 3 are also cylindrical structures. The molded nut 51 is disposed at the axial position of the inner cavity of the cylindrical structure of the second support member 2 and extends downward, while the screw 52 is disposed at the axial position of the inner cavity of the cylindrical structure of the third support member 3 and extends upward. Of course, in other embodiments, the molded nut 51 is disposed at the upper end of the third support member 3, and the screw 52 is disposed at the lower end of the second support member 2.
[0052] To visually demonstrate the height adjustment between the second support member 2 and the third support member 3, optionally, please refer to... Figure 3 and Figure 5 In this embodiment, a second adjustment mark 31 is vertically provided on the outer periphery of the third support member 3. Specifically, the second adjustment mark 31 is a high-precision adjustment mark, including numerical values and scale marks, and the smallest scale unit in the second adjustment mark 31 represents 1 millimeter.
[0053] Another aspect of this utility model embodiment provides a bed frame (not shown in the figure), including a bed frame frame (not shown in the figure) and a support leg 100 detachably assembled to the bottom of the bed frame frame as described above; wherein, the bed frame frame is a furniture frame. Since this bed frame has all the structures and connections of the support leg 100, it has all the advantages of the support leg 100, which will not be elaborated here.
[0054] Example 2
[0055] This embodiment is basically the same as Embodiment 1, except for the placement of the plug-in adjustment structure 4 and the threaded adjustment structure 5.
