[0003] The existing composite guide wheel has a number of holes inside when in use. The holes are intended to reduce the overall weight of the guide wheel. When the composite guide wheel rotates, the airflow passes through the holes inside, thereby forming a specific airflow pattern, such as eddy current or turbulence. These airflow patterns generate noise and are inconvenient for users. Utility Model Content

The plurality of holes are for reducing the overall weight of the guide wheel, and when the composite guide wheel rotates, the airflow passes through the holes inside it, thereby forming a specific airflow pattern, such as eddy current or turbulence, and these airflow patterns will generate noise.

[0005] The utility model provides the following technical solution: a low-density, high-strength, ultra-light composite guide wheel, comprising a composite guide wheel body, the composite guide wheel body is provided with holes inside, the number of the holes is several, and the holes are equidistantly distributed in a ring shape, a sound-absorbing rod is arranged inside the hole, one end of the sound-absorbing rod is threadedly connected with an adjustment mechanism, and the adjustment mechanism can drive the sound-absorbing rod to move linearly.

[0013] The utility model has the following beneficial effects:

[0014] 1. The low-density, high-strength, ultra-light composite guide wheel is provided with holes and sound-absorbing rods. When the composite guide wheel body rotates, the sound-absorbing rods placed in the holes will rotate along with the composite guide wheel body. When the airflow passes through the holes inside the rotating composite guide wheel body, the noise will be sucked in by a number of interrelated sound-absorbing holes in the sound-absorbing rods. When the sound waves enter the holes and contact the sound-absorbing rods, the sound-absorbing rods will absorb the sound wave energy, thereby reducing the propagation and reflection of the sound waves, thereby achieving the effect of reducing noise.

[0015] 2. The low-density, high-strength, ultra-light composite guide wheel is provided with a sound-absorbing rod and an adjustment mechanism. When adjusting the length of the sound-absorbing rod penetrating into the hole, the rotating plate can be rotated. The rotating plate drives the sound-absorbing rod to move to the side away from the screw sleeve through the adjustment mechanism, so that the length of the sound-absorbing rod penetrating into the hole is increased. A longer sound-absorbing rod can absorb more sound waves, thereby improving the noise reduction capability. When the sound-absorbing rods in the hole are of different lengths, these sound-absorbing rods will disrupt the original airflow pattern. This disrupting effect can make the airflow more uniform when passing through the hole, reduce the generation of eddies and turbulence, thereby reducing noise, and further reducing the emission of noise.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 A low-density, high-strength, ultra-light composite guide wheel comprises a composite guide wheel body 1, a plurality of holes 2 are provided inside the composite guide wheel body 1, a plurality of holes 2 are equidistantly distributed in a ring shape, a sound-absorbing rod 3 is provided inside the holes 2, the number of the sound-absorbing rod 3 is the same as the number of the holes 2, one end of the sound-absorbing rod 3 is threadedly connected with an adjustment mechanism, and the adjustment mechanism can drive the sound-absorbing rod 3 to move linearly.

[0024] The adjustment mechanism includes a screw sleeve 401 , which is threadedly connected to the sound absorbing rod 3 , one end of the sound absorbing rod 3 is rotatably connected to a fixing seat 402 , and one side of the fixing seat 402 is fixedly connected to the inner wall of the composite guide wheel body 1 .

[0025] A rotating plate 403 is fixedly connected to the outer side of the screw sleeve 401 , and one side of the rotating plate 403 is rotatably connected to the inner wall of the hole 2 .

[0026] The sound absorbing rod 3 has a plurality of sound absorbing holes 5 formed therein, and the plurality of sound absorbing holes 5 are interconnected.

[0027] The working principle of this embodiment is as follows: when the composite guide wheel body 1 rotates, the sound absorbing rod 3 placed in the hole 2 will rotate along with the composite guide wheel body 1, and when the airflow passes through the hole 2 inside the rotating composite guide wheel body 1, the noise will be sucked in by a number of interrelated sound absorbing holes 5 in the sound absorbing rod 3, and when the sound wave enters the hole 2 and contacts the sound absorbing rod 3, the sound absorbing rod 3 will absorb the sound wave energy, thereby reducing the propagation and reflection of the sound wave, thereby achieving the effect of reducing noise;

[0028] When the sound-absorbing rod 3 is in use, in order to adapt to the different noises in different scenarios where the composite guide wheel body 1 is used, the length of the sound-absorbing rod 3 that penetrates into the hole 2 can be adjusted. During adjustment, the rotating plate 403 is rotated, and the rotating plate 403 drives the screw sleeve 401 to rotate, and the screw sleeve 401 drives the sound-absorbing rod 3 to move to the side away from the screw sleeve 401, so that the length of the sound-absorbing rod 3 that penetrates into the hole 2 is increased. Longer sound-absorbing rods 3 can absorb more sound waves, thereby improving the noise reduction ability. When the sound-absorbing rods 3 in the hole 2 are of different lengths, these sound-absorbing rods 3 will disrupt the original airflow pattern. This disrupting effect can make the airflow more uniform when passing through the hole 2, reduce the generation of eddies and turbulence, thereby reducing noise and further reducing noise emission.

[0033] A connecting seat 8 is fixedly connected to the inner side of the hole 2 , and a groove 9 is formed on one side of the connecting seat 8 , and the groove 9 is gap-matched with the sound-absorbing rod 3 .

[0034] By setting the connecting seat 8 and the groove 9, when the sound absorbing rod 3 moves to the side away from the screw sleeve 401 to the limit distance, the end of the sound absorbing rod 3 enters the groove 9 on one side of the connecting seat 8, thereby restricting and fixing the longer sound absorbing rod 3 to prevent the longer sound absorbing rod 3 from shaking and shifting.

[0035] An extension ring 10 is fixedly connected to one side of the rotating plate 403 , an extension groove 11 is formed on the inner wall of the composite guide wheel body 1 , and the extension ring 10 is slidably connected to the extension groove 11 .
