Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-3 , the present utility model provides an anti-resonance mounting bracket for an axial flow fan, including a bottom plate 1, two sides of the surface of the bottom plate 1 are symmetrically equipped with support plates 2, the inner sides of the two support plates 2 are fixedly equipped with a support platform 3, the support platform 3 is connected to the bottom plate 1 through a partition plate 11, the surface of the support platform 3 is connected with a support 5 through a damping structure 4, a vibration isolation wall 7 is filled and assembled between the support 5 and the support plate 2, and an axial flow fan 6 is fixedly assembled at the upper end of the support 5.

[0017] The overall stability of the equipment is ensured by the bottom plate 1 and the support plate 2. The damping structure 4 is fixed by the support platform 3. Due to the function of the damping structure 4, when the axial flow fan 6 operates and generates vibrations, the vibration force will be offset, preventing resonance between structures such as the support plate 2 and the axial flow fan 6. While ensuring the stability of the axial flow fan 6, the service life of support components such as the support plate 2 is guaranteed. The axial flow fan 6 is protected by the support 5, and due to the function of the vibration isolation wall 7, the horizontal force generated when the axial flow fan 6 operates is blocked, also preventing resonance and ensuring the usage effect of the equipment.

A connecting block 44 is rotatably assembled on the inner wall of the hinge seat 43, and the connecting block 44 is connected to the support 5.

[0019] When the axial flow fan 6 operates, it will produce a small amplitude of vibration effect. At this time, it will drive the connecting block 44 to move on the inner wall of the hinge seat 43, and at the same time drive the damper 42 to work through the hinge seat 43, slowing down the vibration effect and preventing resonance of the supported outer frame body. The support cylinder 41 ensures the stability of the damper 42 during operation.

[0020] It also includes a support structure 9, which is fixedly assembled on the outside of the support plate 2 and is connected to the surface of the bottom plate 1;
