[0044] See also Figure 1-5 , the utility model provides a technical solution: an adjustment device for a fan bracket, comprising a mounting seat 1;

[0045] The mounting seat 1 is provided with a folding limit device to achieve rapid folding and fixing;

[0046] The folding device includes a mounting column 2, a limiting ring 6 and four fixed blocks 15. The mounting column 2 is fixedly connected to the upper surface of the mounting seat 1. The four fixed blocks 15 are fixedly connected to the outer wall of the mounting column 2. The limiting ring 6 is slidably connected to the outer wall of the mounting column 2. Two pull rod grooves 3 are provided on the outer surface of the lower end of the mounting column 2. The insides of the four fixed blocks 15 are rotatably connected to support rods 13. The outer surfaces of the four support rods 13 are fixedly connected to support blocks 12. The outer surface of the protrusion on the limiting ring 6 is slidably connected to the pull rod 4. The end of the pull rod 4 close to the limiting ring 6 slides The pull rod 4 is movable and extends to the interior of the limit ring 6, and one end of the pull rod 4 close to the pull rod groove 3 is in contact with the inner wall of the corresponding pull rod groove 3. The outer wall of the pull rod 4 is sleeved with a first return spring 5, and the two ends of the two first return springs 5 ​​are fixedly connected to the outer wall of the limit ring 6 and the outer wall of the pull rod 4, respectively. The upper surfaces of the four support rods 13 are fixedly connected to the limit fixing blocks 18, and the lower surface of the limit ring 6 is provided with four limit fixing block grooves 16. The ends of the four limit fixing blocks 18 close to the limit fixing block grooves 16 are in contact with the inner walls of the corresponding limit fixing block grooves 16.

[0047] Among them, a sliding column groove 7 is opened on the upper surface of the mounting column 2, and a sliding column 9 is slidably connected inside the sliding column groove 7. The end of the sliding column 9 away from the mounting column 2 is fixedly connected to the mounting block 8. Five limit block grooves 11 are opened on the outer wall of the upper end of the mounting column 2. A second return spring groove 14 is opened on the outer wall of the sliding column 9. The second return spring groove 14 is slidably connected to the limit block 10 inside. The end of the limit block 10 close to the limit block groove 11 is respectively in contact with the corresponding inner wall of the limit block groove 11. The inner wall of the second return spring groove 14 is provided with a second return spring 17. The two ends of the second return spring 17 are respectively fixedly connected to the inner wall of the second return spring groove 14 and the outer wall of one end of the limit block 10.

[0048] Furthermore, when using the device, it is started by connecting an external power supply. First, the limit block 10 is pressed while pulling the sliding column 9, so that the limit block 10 is forced to break contact with the inner wall of the limit block groove 11 and the second return spring 17 contracts. Then, the sliding column 9 can be pulled to adjust the height of the mounting block 8. After adjusting the height of the equipment, the fan can be connected to the mounting block 8 and then transported when necessary.

[0049] Furthermore, pulling the pull rod 4 in the opposite direction drives the first return spring 5 to contract while causing the other end of the pull rod 4 to break contact with the inside of the pull rod groove 3, thereby pulling the limit ring 6 upward to move the support rod 13 to lose the limit, pulling the support rod 13 upward to contract, and then lowering the limit ring 6 while causing the limit fixing block 18 to enter the inside of the limit fixing block groove 16 to limit the support rod 13 and realize the contraction of the support rod 13.

By pressing the limit block 10 and pulling the sliding column 9, the limit block 10 is forced to disengage from the inner wall of the limit block groove 11 and the second return spring 17 is contracted, and then the sliding column 9 can be pulled to adjust the height of the mounting block 8, which is convenient for the staff to adjust the height of the equipment, thereby greatly improving the practicality and flexibility of the equipment.

[0051] Working principle: first, press the limit block 10 and pull the sliding column 9 at the same time, so that the limit block 10 is subjected to force to break contact with the inner wall of the limit block groove 11 and the second return spring 17 contracts. Then you can pull the sliding column 9 to adjust the height of the mounting block 8. After adjusting the height of the equipment, you can connect the fan to the mounting block 8. Then, when it needs to be transported, pull the pull rod 4 to move in the opposite direction to drive the first return spring 5 to contract and make the other end of the pull rod 4 break contact with the inside of the pull rod groove 3. Then, pull the limit ring 6 upward to move the support rod 13 to lose the limit, pull the support rod 13 upward to shrink, and then lower the limit ring 6 while allowing the limit fixing block 18 to enter the inside of the limit fixing block groove 16 to limit the support rod 13 and shrink the support rod 13.
