[0024] Example 1

[0025] Reference Figures 1-4 , is the first embodiment of the present utility model, which provides a side wall fan fixing structure.

[0026] Specifically, a side wall fan fixing structure includes a wind wall 1 and a silent fan 6;

[0027] The wind wall 1 is provided with a through hole 1, and a first fixing component for installing a silent fan 6 is fixed on the wind wall 1;

[0028] The wind installation wall 1 is provided with a second fixing component for assisting the first fixing component in fixing and installing the silent fan 6 . The second fixing component can be adjusted according to the size of the silent fan 6 .

[0029] The first fixing component includes a first mounting plate 2 fixedly mounted on the mounting wind wall 1, a second through hole is opened on the first mounting plate 2, and the second through hole is coaxially distributed with the through hole, a plurality of mounting seats 3 are evenly fixed on the first mounting plate 2, and an integrally welded mounting frame 4 is provided on the first mounting plate 2, and the mounting frame 4 is fixedly connected to the first mounting plate 2 through the mounting seat 3.

[0030] The mounting frame 4 is divided into a mounting portion and a supporting portion. The supporting portion is two connecting rods with a top projection of a U-shape. One end of the two supporting portions is connected to the mounting portion to form a mounting space.

[0031] A motor 5 is provided on one side of the mounting portion, and a driving end of the motor 5 is transmission-connected to a silent fan 6 .

[0032] The second fixing assembly includes a second mounting plate 101 fixed to the other side of the mounting wind wall 1, and a connecting seat 102 and a connecting seat 2 103 are arranged side by side on the second mounting plate 101, and a rotating rod 104 and a rotating rod 2 105 are hingedly provided on the connecting seat 102 and the connecting seat 2 103 respectively, and a torsion spring for resetting is provided between the connecting seat 2 103 and the rotating rod 2 105, and the rotating rod 1 104 and the rotating rod 2 105 are hinged by a connecting plate 106, and a connecting plate 2 107 is also hingedly provided on the rotating rod 104 and the rotating rod 2 105, and a pressing piece is symmetrically provided on the connecting plate 2 107, and the pressing piece is used to assist the silent fan 6 in entering hole 1 and hole 2 and cooperating and pressing.

[0033] The first and second rotating rods 104 and 105 are hingedly connected to the first and second connecting bases 102 and 103, forming a lever structure. When an external force is applied to the first rotating rod 104, it can drive the second rotating rod 105 and the pressing member on the second connecting plate 107 to move, thereby pressing and fixing the silent fan 6.

[0034] The clamping member includes a mounting block 108 symmetrically arranged on both sides of the connecting plate 107, and a sliding groove is provided on the mounting block 108. A clamping block 109 is slidingly provided in the sliding groove. A plurality of springs 1010 are provided between the mounting block 108 and the clamping block 109. The projection of the clamping block 109 is trapezoidal, and the inner side of the clamping block 109 is provided with friction lines that increase friction.

[0035] Among them, spring 1010 plays a key role in the compression piece. It can undergo elastic deformation when the clamping block 109 is subjected to external force, thereby absorbing and buffering part of the impact force, ensuring that the clamping block 109 can fit tightly against the surface of the silent fan 6. At the same time, the elastic recovery force of spring 1010 can also ensure that after the external force is removed, the clamping block 109 can quickly return to its original position and continue to compress the silent fan 6. The friction pattern design on the inside of the clamping block 109 can increase the friction coefficient of the contact surface with the silent fan 6, thereby improving the fixing effect of the compression piece. During the test process, even if affected by external forces such as airflow, the silent fan 6 can maintain a stable position, ensuring the accuracy of the test results.

[0036] In summary, first, the silent fan 6 is preliminarily fixed to the mounting wind wall 1 by the first fixing component. Specifically, the corresponding part of the silent fan 6 passes through the through hole 1 on the mounting wind wall 1 and the through hole 2 on the first mounting plate 2, and then the fixed part of the silent fan 6 is connected to the driving end of the motor 5 using the mounting space provided by the mounting frame 4 and its supporting part. The motor 5 is responsible for driving the silent fan 6 to rotate to generate the airflow required for the test. Next, the second fixing component plays a role in auxiliary fixation and adjustment. According to the specific size of the silent fan 6, the silent fan 6 can be further tightened and fixed by adjusting the angle between the rotating rod 1 104 and the rotating rod 2 105, as well as the position of the clamping piece on the connecting plate 2 107. Specifically, when the rotating rod 104 and the rotating rod 2 105 rotate on the connecting seat 102 and the connecting seat 2 103, since a torsion spring is provided between the connecting seat 2 103 and the rotating rod 2 105, the rotating rod 2 105 can automatically reset when not affected by external forces, which is convenient for positioning and fixing during the adjustment process. The connecting plate 106 and the connecting plate 2 107 play the role of connecting and transmitting force, so that the rotation of the rotating rod 104 and the rotating rod 2 105 can be converted into the pressing force of the clamping member on the silent fan 6. The clamping member achieves a tight fit and fixation on the silent fan 6 through the elastic action of the clamping block 109 in the slide groove and the spring 1010. The trapezoidal projection design of the clamping block 109 and the friction lines on the inside can increase the friction and stability of the contact surface with the silent fan 6, ensuring that the silent fan 6 will not shake or shift during the test.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
