[0036] like Figure 1 As shown, an auxiliary device for installing an axial flow fan comprises a base, two sides of which are symmetrically fixedly connected to a first support column 2 and a second support column 3, the first support column 2 and the second support column 3 are respectively movably connected to a first adjustment column 4 and a second adjustment column 5, and the tops of the first adjustment column 4 and the second adjustment column 5 are fixedly connected to a support plate 6;

[0037] A first slide groove 7 and a second slide groove 8 are provided on the top of the support plate 6. The opening of the first slide groove 7 is upward, and the second slide groove 8 is provided at the front of the support plate 6. One side of the second slide groove 8 is connected to the outside, and the other side is connected to the first slide groove 7; a movable plate 9 is provided in the first slide groove 7, and a movable groove 10 is provided on the inner side of the movable plate 9. A slider 12 is provided in the movable groove 10, and the slider 12 is connected to the first screw rod 11. The bottom of the first screw rod 11 is rotatably connected to the bottom of the movable plate 9, and the first screw rod 11 passes through the top of the movable plate 9; a clamping block 13 is installed on the slider 12;

[0038] A support rod 14 is provided in the second slide groove 8, and the two ends of the support rod 14 are movably connected to two connecting plates 15 (generally, the two ends of the support rod 14 pass through the two connecting plates 15 respectively), and the connecting plate 15 is fixed to the bottom of the movable plate 9; a spring 16 is provided between the two connecting plates 15, and the spring 16 is sleeved on the support rod 14 (such as Figure 2 As shown, Figure 2 Some parts are partially hidden so that the related structures can be better seen. For example, there should be a part of the support plate 6 structure on the side of the connecting plate 15, and the right part of the front side of the support plate 6 is hidden so that the support rod 14, spring 16 and other structures can be seen); the spring 16 is movably connected to the connecting plate 15, such as Figure 3 As shown, a locking assembly is provided at the end of the connecting plate 15, and the locking assembly includes a locking head 18 and a fixing rod 17. The locking head 18 is provided with an arc groove 19 and an arc limiter 20 cooperating with the arc groove 19; the fixing rod 17 is provided with a locking hole 21, and the arc limiter 20 cooperates with the locking hole 21 to play a role in fixing the position of the locking head 18.

[0039] In this embodiment, a clamping block 13 is provided, through which the axial flow fan can be clamped, which is particularly suitable for axial flow fans of smaller size. When used specifically, the axial flow fan is placed on the support plate 6, and the first screw 11 is rotated to drive the slider 12 to move up and down in the movable groove 10, thereby driving the clamping block 13 to move up and down; in general, the clamping block 13 is adjusted to the maximum height position with the outer contour of the middle part of the axial flow fan. The lock heads 18 on both sides of the movement drive it to move toward each other on the outer surface of the fixed rod 17, and at the same time drive the connecting plates 15 on both sides to move toward each other in the second slide groove 8 and the outer surface of the support rod 14 and squeeze the spring 16, thereby driving the moving plates 9 on both sides to move toward each other in the first slide groove 7. After adjusting to the appropriate position, the arc stopper 20 is rotated to make the arc stopper 20 pass through the locking hole 21 at the corresponding position of the fixed rod 17, thereby limiting the position of the moving plate 9 in the first slide groove 7, and the clamping block 13 clamps the axial flow fan to the support plate 6. This embodiment can fix axial flow fans of different sizes and heights to facilitate subsequent rapid installation of the axial flow fans, and is easy to use.

[0040] In a preferred embodiment, if Figure 5 As shown, a third slide groove 24 and a fourth slide groove 25 are respectively provided on one side of the first support column 2 and the second support column 3, an adjustment plate 26 is provided between the third slide groove 24 and the fourth slide groove 25, and both ends of the adjustment plate 26 are fixedly connected to the bottom of the first adjustment column 4 and the second adjustment column 5 respectively.

[0041] A fixing plate 27 is disposed between the first supporting column 2 and the second supporting column 3 . A second screw 29 is disposed on the fixing plate 27 . The second screw 29 is rotatably connected to the fixing plate 27 . The second screw 29 is threadedly connected to the adjusting plate 26 .

[0042] The base is provided with a rotation groove 30, and a limit plate 31 is provided in the rotation groove 30. The limit plate 31 can rotate in the rotation groove 30; the bottom of the second screw rod 29 passes through the upper wall of the rotation groove 30 and is fixedly connected to the limit plate 31. The base can be formed by splicing two parts. Through the setting of the rotation groove 30 and the limit plate 31, the second screw rod 29 rotates and drives the limit plate 31 to rotate in the rotation groove 30, so that the second screw rod 29 can be stably supported, so as to better support and adjust the height of the support plate 6. Generally, the rotation groove 30 is a circular space, and the limit plate 31 is a circular plate.

[0043] During specific use, through the settings of the third slide groove 24, the fourth slide groove 25, the adjustment plate 26, the fixed plate 27, the limiting hole 28 (arranged at the connection between the second screw 29 and the base) and the second screw 29, when it is necessary to adjust the installation height of the axial flow fan, the second screw 29 is rotated to drive it to rotate on the inner wall of the limiting hole 28, thereby driving the adjustment plate 26 to move up and down, and at the same time driving the first adjustment column 4 and the second adjustment column 5 to move up and down in the first support column 2 and the second support column 3 respectively, thereby adjusting the height of the support plate 6 and then facilitating the adjustment of the installation height of the axial flow fan, which is convenient for adjustment.

[0044] In a preferred embodiment, if Figure 4 As shown, the clamping block 13 is provided with an arc-shaped portion, and a gasket 22 is fixedly provided on the inner wall of the arc-shaped portion. The gasket 22 has a certain thickness, which makes it easier for the arc-shaped limiter 20 to cooperate with the locking hole 21. Generally, a number of equally spaced locking holes 21 are provided on the fixing rod 17, but it is not always possible to fix the axial flow fan at a suitable locking hole 21 position. Therefore, it is best to set a certain adjustment margin. This margin can be achieved by the thickness of the gasket 22. For example, the thickness of the gasket 22 is set to 2cm, and a certain margin can be generated by squeezing the gasket 22. When the locking hole 21 closest to the axial flow fan cannot lock the axial flow fan, the thickness of the gasket 22 can make up for this gap margin, so that after the arc-shaped limiter 20 is locked with the corresponding locking hole 21, the structure of the clamping block 13 and the gasket 22 can lock the axial flow fan. The gasket 22 generally adopts a rubber pad, and the rubber pad is pasted on the clamping block 13. In addition, the clamping block 13 plays a protective role when clamping the axial flow fan, thereby preventing the outer surface of the axial flow fan from being worn during the clamping process.

[0045] In a preferred embodiment, if Figure 4As shown, a first knob 23 is disposed on the top of the first screw rod 11. When in use, the first knob 23 is installed and arranged, and the first screw rod 11 can be driven to rotate by rotating the first knob 23, so that the first screw rod 11 is easily rotated.

[0046] In a preferred embodiment, if Figure 5 As shown, the top of the second screw rod 29 passes through the fixing plate 27, and a second knob 32 is provided on the top of the second screw rod 29. The second knob 32 is installed and arranged, and the second screw rod 29 can be driven to rotate by turning the second knob 32, so as to facilitate the rotation of the second screw rod 29.

[0047] In a preferred embodiment, a paddle is provided at the end of the arc-shaped stopper 20, and one end of the paddle is located in the arc-shaped groove 19. The paddle can make the arc-shaped stopper 20 easy to operate on one hand, and can also play a limiting role on the other hand. The arc-shaped stopper 20 is limited by the paddle and thus will not be separated from the arc-shaped groove 19.

[0048] In a preferred embodiment, an auxiliary walking device is provided on the base.

[0049] In a preferred embodiment, the auxiliary walking device includes at least three universal wheels 33, and the universal wheels 33 are installed on the base. Figure 1 As shown, a universal wheel 33 is respectively arranged at the four corners of the base. The universal wheel 33 is installed to facilitate the position of the mobile device, thereby facilitating the position of the axial flow fan and thus facilitating the installation of the axial flow fan.

[0050] Working principle: In use, the axial flow fan is placed on the support plate 6, and the first screw 11 is rotated to drive the slider 12 to move up and down in the moving groove 10, thereby driving the clamping block 13 to move up and down, so as to adjust the clamping block 13 to a height consistent with the maximum outer diameter of the middle part of the axial flow fan, and the lock heads 18 on both sides are moved to drive it to move toward each other on the outer surface of the fixed rod 17, and at the same time drive the connecting plates 15 on both sides to move toward each other in the second slide groove 8 and the outer surface of the support rod 14 and squeeze the spring 16, thereby driving the moving plates 9 on both sides to move toward each other in the first slide groove 7, and after adjusting to the appropriate position, the arc limiter 20 is rotated until the arc limiter 20 is inserted into the locking hole 21. The position of the moving plate 9 is limited and fixed in the first slide groove 7, so that the axial flow fan can be clamped and limited and fixed on the support plate 6 through the clamping block 13, which is convenient for limiting and fixing axial flow fans of different sizes and heights so as to facilitate the subsequent rapid installation of the axial flow fan, and is easy to use. When the installation height of the axial flow fan needs to be adjusted, the second screw 29 is rotated to drive it to rotate in the limit hole 28, thereby driving the adjustment plate 26 to move up and down, and at the same time driving the first adjustment column 4 and the second adjustment column 5 to move up and down in the first support column 2 and the second support column 3, thereby adjusting the height of the support plate 6 and thus facilitating the adjustment of the installation height of the axial flow fan, which is convenient for adjustment.
