Detailed Description
All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples: referring to fig. 1-3, the main components of the present case are: the circular tube 1 is internally provided with a silencing structure, and the outer wall of the circular tube is provided with a damping structure;
the noise reducing structure comprises: a silencing cavity 2, a first silencing material 3, a second silencing material 4, a central plate 5 and a plurality of partition plates 6;
the silencing cavity 2 is formed in the circular tube 1, the first silencing material 3 is arranged on the wall surface of the silencing cavity 2, the second silencing material 4 is arranged on the inner wall of the first silencing material 3, the center plate 5 is arranged at the center of the silencing cavity 4, the plurality of partition plates 6 are respectively arranged on the center plate 5 and the second silencing material 4, the plurality of partition plates 6 are arranged on the second silencing material 4, part of partition plates 6 and the plurality of partition plates 6 are arranged on the center plate 5 in a staggered mode, and the intervals among the plurality of partition plates 6 are the same.
When the air flow enters the silencing cavity 2 in the circular tube 1, the noise is partially reduced by the first silencing material 3 and the second silencing material 4, the effective tissue noise is spread outwards, the air flow moves to the partition plate 5, and moves along the gap formed by the special arrangement of the partition plate 5, so that the air flow is blocked to lose the self transmission energy, weaken the noise and finish the silencing work.
In an implementation process, the shock absorbing structure further includes: a pair of clamping plates 7, a plurality of limiting grooves 8, a pair of bolts 9, a pair of limiting rods 10, a plurality of springs 11, a pair of fixing plates 12 and a pair of circular rings 13;
