[0040] The embodiment provides a stepless adjustment support leg for supporting devices such as furniture, office equipment, mechanical equipment, etc., which can realize the adjustment of the support height. Figures 1-8As shown, the stepless adjustment support foot comprises a movable foot 100 and a bottom support foot 200, wherein the movable foot 100 comprises a connecting portion 110 and a pressing member 10, the pressing member 10 is movably connected to the connecting portion 110; the bottom support foot 200 comprises a mounting cylinder 210 and a movable member 20, the pressing member 10 is at least partially inserted into the mounting cylinder 210, the movable member 20 is adjacent to the pressing member 10, the movable member 20 is rotatable relative to the mounting cylinder 210, the force of the movable member 20 on the pressing member 10 is adjusted, so as to change the connection relationship between the pressing member 10 and the mounting cylinder 210.
[0041] Further, as shown in Figure 5 When the movable member 20 is rotated to the first position, the movable member 20 drives the pressing member 10 to press the inner wall of the mounting cylinder 210; as shown in Figure 6 When the movable member 20 is rotated to the second position, the movable member 20 drives the pressing member 10 to be separated from the inner wall of the mounting cylinder 210.
[0042] Specifically, the stepless adjustment support foot provided by the embodiment is telescopic by moving the movable foot 100 relative to the bottom support foot 200, the mounting cylinder 210 of the bottom support foot 200 is provided with the movable member 20, the movable member 20 is rotatable relative to the mounting cylinder 210, so as to make the pressing member 10 press or release the inner wall of the mounting cylinder 210. When the movable member 20 is rotated to the first position, the movable member 20 presses the pressing member 10 to the inner wall of the mounting cylinder 210, the position of the pressing member 10 is limited, at this time, the movable foot 100 cannot be telescopically moved, the length of the stepless adjustment support foot is locked; when the movable member 20 is rotated to the second position, the movable member 20 drives the pressing member 10 to be released from the inner wall of the mounting cylinder 210, at this time, the user can directly pull the movable foot 100 to adjust the distance between the movable foot 100 and the bottom support foot 200, so as to realize stepless adjustment, after the adjustment is completed, the movable member 20 is rotated to the first position, so as to be re-locked. In summary, the movable foot 100 can be locked or unlocked by rotating the movable member 20, so as to quickly adjust the support height, without adjusting the support height by rotating the movable foot 100, the adjustment efficiency is high, the manpower is saved, and the user experience is improved.
[0043] Exemplarily, as shown in Figures 4-7 The pressing member 10 comprises a pressing portion 11 and an unlocking portion 12, the unlocking portion 12 is movably connected to the connecting portion 110, the pressing portion 11 extends outward from the surface of the unlocking portion 12, one end of the pressing portion 11 is connected to the peripheral wall of the connecting portion 110, and the other end extends outward along an arc-shaped path. When the movable member 20 is rotated to the first position, the movable member 20 abuts against the pressing portion 11 and drives the pressing portion 11 to press the inner wall of the mounting cylinder 210; when the movable member 20 is rotated to the second position, the movable member 20 abuts against the unlocking portion 12 and drives the pressing portion 11 to be separated from the inner wall of the mounting cylinder 210.
[0044] Exemplarily, as shown in Figures 4-7As shown, the abutting part 11 comprises an abutting section 111 and a transition section 112, the transition section 112 is connected with the abutting section 111 and the unlocking part 12 at two ends respectively, and the thickness of the transition section 112 gradually decreases in the direction away from the abutting section 111; when the movable part 20 rotates to the first position, the movable part 20 presses against the inner side wall of the abutting section 111, and the outer side wall of the abutting section 111 abuts against the inner wall of the mounting cylinder 210. When the movable part 20 rotates towards the second position, the movable part 20 still abuts against the inner side wall corresponding to the front section of the transition section 112 close to the abutting section 111 in the previous stage, and gradually separates from the inner side wall corresponding to the rear section of the transition section 112 close to the unlocking part 12 in the subsequent stage. At this time, after the movable part 20 completely separates from the abutting section 111 and during the process of passing through the transition section 112, the movable part 20 still abuts against the inner side wall corresponding to the transition section 112 for a period of time, and the friction force between the abutting part 11 and the mounting cylinder 210 still exists and decreases linearly.
