[0030] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0031] Example 1:

[0032] See Figure 1 A vibration damping device for a fan outlet pipe includes a platform 1 with an internal through groove 3 and supports 2 disposed at both ends of the platform 1. The vibration damping device for the fan outlet pipe further includes:

[0033] The first mounting block 4 is set in the through groove 3. The upper end of the first mounting block 4 is hinged to the first clamping plate 5. A first spring shock absorber 6 is provided between the first clamping plate 5 and the first mounting block 4.

[0034] The second mounting block 7 is located in the through groove 3 and on one side of the first mounting block 4. The upper end of the second mounting block 7 is hinged to a second clamping plate 8, and a second spring shock absorber 9 is provided between the second clamping plate 8 and the second mounting block 7.

[0035] The first mounting block 4 and the second mounting block 7 are fixedly connected to the through groove 3.

[0036] Specifically, the upper end face of the support 2 is fixedly connected to the lower end faces of both sides of the platform 1 to support the entire device; the first mounting block 4 and the second mounting block 7 are fixed in the through groove 3. The upper end of the first mounting block 4 is hinged to the first clamping plate 5 through a rotating shaft. The upper part of the first clamping plate 5 extends out from the groove opening of the through groove 3. The two ends of the first spring shock absorber 6 are movably connected to the first clamping plate 5 and the first mounting block 4, respectively. The upper end of the second mounting block 7 is hinged to the second clamping plate 8 through a rotating shaft. The upper part of the second clamping plate 8 extends out from the groove opening of the through groove 3. The two ends of the second spring shock absorber 9 are movably connected to the second clamping plate 8 and the second mounting block 7, respectively. The first clamping plate 5, the second clamping plate 8 and the end face of the platform 1 together form a space for supporting and clamping the fan outlet pipe.

[0037] When the fan is running, it generates high-frequency vibrations, which are transmitted to the outlet pipe. Since the outlet pipe of a traditional fan is usually suspended, the vibration amplitude is large, causing the vibration of the outlet pipe to exceed the standard. Therefore, in this embodiment, a platform 1, a first clamping plate 5, and a second clamping plate 8 are provided. In use, the support 2 is fixed, and the fan outlet pipe is placed in the space formed by the end face of the first clamping plate 5, the second clamping plate 8, and the platform 1. The outlet pipe is supported by the platform 1 and clamped and fixed by the first clamping plate 5 and the second clamping plate 8, thereby reducing its vibration amplitude and avoiding the situation where other equipment is interlocked and shut down due to excessive vibration of the outlet pipe. In addition, this embodiment also provides a first spring shock absorber 6 and a second spring shock absorber 9. When the fan outlet pipe vibrates, the two absorb the vibration, further improving the vibration reduction effect of the vibration reduction device.

[0038] Example 2:

[0039] See Figure 2 and Figure 3 Based on Embodiment 1, and optionally, the first mounting block 4 and the second mounting block 7 are slidably connected to the through groove 3.

[0040] Specifically, the left, right, and top sides of the first mounting block 4 and the second mounting block 7 have certain gaps with the left, right, and upper inner walls of the through groove 3, respectively. The bottoms of the first mounting block 4 and the second mounting block 7 are slidably connected to the bottom of the through groove 3. This arrangement allows the first mounting block 4 and the second mounting block 7 to move linearly within the through groove 3. Once the first mounting block 4 and the second mounting block 7 have moved to the target distance, they can be fixed with screws.

[0041] Further and optionally, a first rack 10 is fixed to one side of the first mounting block 4, and a second rack 11 is fixed to one side of the second mounting block 7. An adjusting gear 12 is provided between the first rack 10 and the second rack 11, and the adjusting gear 12 meshes with the first rack 10 and the second rack 11 respectively.

[0042] Specifically, the first rack 10 can be positioned above the second rack 11, or the first rack 10 can be positioned below the second rack 11. The adjusting gear 12 is positioned between the first rack 10 and the second rack 11. One end of the gear shaft 13 of the adjusting gear 12 is provided with a bearing seat. The position of the adjusting gear 12 is installed and fixed through the bearing seat. The adjusting gear 12 rotates around the bearing seat as the center, while simultaneously driving the first rack 10 and the second rack 11 to move horizontally in a straight line.

[0043] When the adjusting gear 12 rotates clockwise, it drives the first rack 10 to move to the right and the second rack 11 to move to the left, so that the first mounting block 4 and the second mounting block 7 move closer to each other, thereby reducing the distance between the first clamping plate 5 and the second clamping plate 8. When the adjusting gear 12 rotates counterclockwise, it drives the first rack 10 to move to the left and the second rack 11 to move to the right, so that the first mounting block 4 and the second mounting block 7 move further apart, thereby increasing the distance between the first clamping plate 5 and the second clamping plate 8. In this way, the clamping size can be adjusted.

[0044] Further and optionally, the side of the platform 1 is provided with a through hole that allows the gear shaft 13 of the adjusting gear 12 to pass through, and one end of the gear shaft 13 is connected to a handle 14 through the through hole.

[0045] like Figure 3 As shown, the rotating handle 14 is located outside the through groove 3. By applying force to the rotating handle 14, the adjusting gear 12 is rotated, thereby realizing the adjustment of the clamping size.

[0046] Further and optionally, the surfaces of the first clamping plate 5 and the second clamping plate 8 are both covered with a soft rubber layer.

[0047] The soft rubber layer is elastic at room temperature and can undergo large deformation under a small external force. It can return to its original shape after the external force is removed. The soft rubber layer can absorb the vibration of the fan outlet pipe through elastic deformation, thereby further improving the vibration reduction effect.

[0048] Furthermore, and optionally, the bottom of the support 2 is provided with a self-locking caster wheel 15.

[0049] The self-locking caster wheel 15 can rotate 360° and lock at the same time. By setting the self-locking caster wheel 15, the movement and fixation of the vibration damping device can be realized.

[0050] Further and optionally, a reinforcing rib 16 is fixed between the platform 1 and the support 2.

[0051] Specifically, one end of the reinforcing rib 16 is fixedly connected to the bottom surface of the support 2, and the other end is fixedly connected to the side wall of the platform 1. In this way, the support of the platform 1 is more stable and the load capacity is greater.

[0052] In this embodiment, the fixed connection between the first mounting block 4, the second mounting block 7, and the through groove 3 in Embodiment 1 is changed to a sliding connection. A first rack 10 is fixed to one side of the first mounting block 4, and a second rack 11 is fixed to one side of the second mounting block 7. An adjusting gear 12 is provided between the first rack 10 and the second rack 11, so that the clamping size between the first clamping plate 5 and the second clamping plate 8 can be adjusted, thereby making the vibration damping device suitable for fan ducts of different sizes. At the same time, based on Embodiment 1, in this embodiment, a soft rubber layer is added to the surface of the first clamping plate 5 and the second clamping plate 8. The soft rubber layer can absorb the vibration of the fan outlet duct through elastic deformation, thereby further improving the vibration damping effect.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
