[0024] Please see Figure 1-5This utility model provides a technical solution: a movable foot support assembly for a fan, including a movable foot support assembly body 1 and a fan 4. The movable foot support assembly body 1 is mounted on the fan 4. The body 1 has a first support frame 2 and a second support frame 7 with identical shapes and structures. The first support frame 2 has a U-shaped structure, and stabilizing diagonal bars 201 are symmetrically welded and fixed to its inner side. The first support frame 2 is movably engaged with the fan duct structure of the fan 4. This structure makes the first support frame 2 structurally stable. Since the second support frame 7 has the same structure as the first support frame 2, the first support frame 2 and the second support frame 7 provide two sets of reliable adjustable support structures for the fan 4, allowing for height adjustment of the fan 4 according to its positioning requirements. The angle is adjusted to ensure the structural stability of the fan 4. The bottom of the first support frame 2 is symmetrically fixed with adjusting positioning rods 202. A movable adjusting sleeve 3 is also symmetrically provided below the first support frame 2. An arc-shaped limiting groove 203 is formed on the outside of the adjusting positioning rod 202, and the limiting groove 203 is located inside the movable adjusting sleeve 3. This structure allows the adjusting positioning rod 202 to be positioned relative to the movable adjusting sleeve 3 through the limiting groove 203. Limiting holes 302 are evenly spaced on the upper side of the movable adjusting sleeve 3, and a fastening thread 304 is also provided on the lower outer ring of the movable adjusting sleeve 3. The movable adjusting sleeve 3 has a straight cylindrical structure. By rotating the movable adjusting sleeve 3, it can be positioned relative to the adjusting positioning rod 202. The position rod 202 rotates to avoid torque damage. The rotation of the movable adjusting sleeve 3 relative to the movable support rod 5 allows the movable adjusting sleeve 3 to move under the positioning of the movable support rod 5, thereby achieving length adjustment of the movable leg formed by the movable adjusting sleeve 3 and the movable support rod 5. The limiting hole 302 and the limiting groove 203 are correspondingly positioned, and a ball bearing 303 is engaged in both the limiting hole 302 and the limiting groove 203. This structure ensures reliable positioning of the ball bearing 303. Through the cooperation of the limiting hole 302 and the limiting groove 203, the ball bearing 303 also achieves rotational locking of the movable adjusting sleeve 3 and the adjusting positioning rod 202, preventing the movable adjusting sleeve 3 from falling off the adjusting positioning rod 202. Furthermore, the movable adjusting sleeve 3 is secured internally by a threaded connection... The structure includes a movable support rod 5, and a movable adjusting sleeve 3 is rotatably engaged with an adjusting positioning rod 202. A fastening sleeve 301 is also securely fastened to the upper end of the movable adjusting sleeve 3, and the fastening sleeve 301 engages with a ball bearing 303. The fastening sleeve 301 and the adjusting positioning rod 202 are also movably connected. This structure allows the fastening sleeve 301 to position the ball bearing 303, ensuring a secure connection between the ball bearing 303 and the movable adjusting sleeve 3 and the adjusting positioning rod 202. Simultaneously, the rotation of the movable adjusting sleeve 3 relative to the adjusting positioning rod 202 reduces resistance. A universal joint ball 501 is integrally provided at the bottom of the movable support rod 5, and a positioning and stabilizing foot 6 is provided below the movable support rod 5, which movably engages with the universal joint ball 501.The movable support rod 5 is fitted with an internally threaded fastening collar 502 via a threaded structure, and the internally threaded fastening collar 502 is threadedly fastened to the fastening thread 304. After the movable adjusting sleeve 3 is adjusted relative to the movable support rod 5, the internally threaded fastening collar 502 can lock the movable support rod 5 and the movable adjusting sleeve 3 via the fastening thread 304, ensuring the stability of the support. The positioning and stabilizing foot 6 has a frustum-shaped structure, and an inner support member 601 is fixed inside the positioning and stabilizing foot 6 via a threaded structure. This structure allows the movable support rod 5 to pass through the bottom of the positioning and stabilizing foot 6, and then be supported by the universal joint ball 501 through the inner support member 601, ensuring the stability of the connection between the positioning and stabilizing foot 6 and the movable support rod 5. At the same time, the universal joint ball 501 can rotate under the support of the inner support member 601. The upper end of the inner support member 601 is connected to the universal joint ball 501. The movable support rod 5 is connected by a snap-fit ​​mechanism, with the bottom of the inner support member 601 securely engaged with the inherent anti-slip pad 602. This structure allows the universal joint ball 501 to be locked via the inner support member 601, enabling the movable support rod 5 to rotate in cooperation with the universal joint ball 501 and the inner support member 601. By adjusting the angles of the movable support rod 5 and the positioning foot 6, the positioning foot 6 can be supported on uneven ground. Simultaneously, the movable support rod 5 can cooperate with the first support frame 2 and the second support frame 7 to provide support at different angles. The second support frame 7 is used for overall anti-slip support and shock absorption. The fan 4 has symmetrically fixed positioning seats 401 on its side, with connecting pins 402 at both ends of the positioning seats 401 that penetrate and connect to the first support frame 2 and the second support frame 7, respectively, allowing the angle of the fan 4 relative to the first support frame 2 and the second support frame 7 to be adjusted.

[0025] Working Principle: When using this fan movable foot support assembly, firstly, the external sides of the fan 4 are fixed with welding positioning seats 401 for connecting and positioning the main body 1 of the movable foot support assembly to the fan 4's air duct. The first support frame 2 and the second support frame 7 are respectively connected to the fan 4's air duct via connecting shaft pins 402 for adjustable angle positioning, allowing for precise adjustment of the fan 4's angle. Then, the first support frame 2 and the second support frame 7 are adjusted to different degrees in height and positioning angle to ensure that the fan 4 has a reliable positioning structure. Taking the adjustment of the first support frame 2 as an example, the movable adjusting sleeve 3 is rotated. The height is adjusted by the movement of the movable adjusting sleeve 3 relative to the movable support rod 5. The movable adjusting sleeve 3 is rotated and positioned by adjusting the positioning rod 202, and the stabilizing diagonal rod 201 is used for the first support frame. The structure of 2 is reinforced. The ball bearing 303, positioned by the limiting hole 302, cooperates with the limiting groove 203 to lock and prevent the positioning rod 202 from falling off. The fastening sleeve 301 is used to install and position the ball bearing 303. Then, the internal thread fastening ring 502 is rotated so that it cooperates with the fastening thread 304 to lock the movable adjusting sleeve 3 and the movable support rod 5. The positioning and stabilizing foot 6 is supported on the ground by the anti-slip pad 602. The inner support 601 is supported by the universal connecting ball 501 inside the positioning and stabilizing foot 6. The universal connecting ball 501 and the positioning and stabilizing foot 6 rotate relative to each other to adjust the relative angle between the movable support rod 5 and the positioning and stabilizing foot 6, ensuring the reliable positioning of the movable foot support assembly 1 on the fan 4, thereby completing a series of operations.
