In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pipeline damping bump leveller of sound attenuation and vibration reduction, includes go-between, fixed frame, bracing piece, stopper, inhales sound piece and pipeline body, the outer welded fastening of go-between has fixed frame, and the inside welded fastening of fixed frame has reset spring to the inside of fixed frame is provided with the bracing piece, the outer welded fastening of bracing piece has the stopper, and the inboard of stopper is provided with inhales the sound piece to inhale the front surface of sound piece and seted up the ventilation hole, the surface of stopper is provided with the pipeline body moreover.
Preferably, the connecting ring is made of metal, and the connecting mode between the connecting ring and the sound absorption block is bonding.
Preferably, the fixing frames are welded and fixed on the outer surface of the connecting ring at equal angles, the fixing frames and the support rods form a sliding structure, and the fixing frames are provided with four groups.
Preferably, the support rod and the fixing frame form an elastic structure through a return spring, the deformation amount of the return spring is smaller than the length of the fixing frame, and the outer diameter of the return spring is equal to the inner diameter of the fixing frame.
Preferably, the shape of the limiting block is arc-shaped, the limiting block corresponds to the fixing frame one by one, and two sides of the limiting block are inclined.
Preferably, inhale the sound piece and inlay with the space of stopper, bracing piece, fixed frame and go-between deformation and be connected, and inhale the front surface of sound piece and run through and seted up the ventilation hole.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) this pipeline damping bump leveller that subtracts sound and shake is provided with the stopper, reset spring and bracing piece, deformation through reset spring, can make the bracing piece obtain adjusting in the position, thereby make the stopper can be tightly order the inboard at the pipeline body, then make pipeline damping bump leveller more easy to assemble, staff's efficiency has been improved, staff's intensity of labour has also been reduced simultaneously, and inhale the sound through inhaling the sound piece, experience when making people use the air conditioner feels better, under reset spring's energy-absorbing, can make pipeline damping bump leveller fixed hang when the pipeline body is inside, still can carry out the energy-absorbing to vibrations, then reduced the junction because vibrations and the probability that the damage condition takes place appears.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a pipeline damping bump leveller of sound attenuation and vibration reduction, including go-between 1, fixed frame 2, reset spring 3, bracing piece 4, stopper 5, inhale sound piece 6, ventilation hole 7 and pipeline body 8, the outer welded fastening of go-between 1 has fixed frame 2, and the inside welded fastening of fixed frame 2 has reset spring 3, and the inside of fixed frame 2 is provided with bracing piece 4, the outer welded fastening of bracing piece 4 has stopper 5, and the inboard of stopper 5 is provided with inhales sound piece 6, and ventilation hole 7 has been seted up to the front surface of inhaling sound piece 6, and the surface of stopper 5 is provided with pipeline body 8.
The material of go-between 1 is metal, and go-between 1 and inhale the connected mode between sound piece 6 for bonding, can make and inhale the better fixed of sound piece 6 to make and inhale that sound piece 6 can be better protect the pipeline.
The fixed frame 2 is welded and fixed on the outer surface of the connecting ring 1 at equal angles, the fixed frame 2 and the support rods 4 form a sliding structure, and the fixed frame 2 is provided with four groups, so that the whole device can be effectively fixed inside the pipeline body 8.
The bracing piece 4 constitutes elastic construction through reset spring 3 and fixed frame 2, and the deformation volume of reset spring 3 is less than the length of fixed frame 2 to reset spring 3's external diameter equals the internal diameter of fixed frame 2, can make the installation of whole device more convenient, has reduced staff's work load, has also improved the installation effectiveness of pipeline damping bump leveller simultaneously.
The appearance of stopper 5 is circular-arcly, and stopper 5 and fixed frame 2 one-to-one to the both sides of stopper 5 are the slope form, can make stopper 5 gather in 8 inboard processes of pipeline body, the condition of interference can not appear between multiunit stopper 5.
Inhale sound piece 6 and be connected with the space of stopper 5, bracing piece 4, fixed frame 2 and go-between 1 deformation is inlayed, and inhale the front surface of sound piece 6 and run through and seted up ventilation hole 7, can guarantee that the air current passes through smoothly, also is the noise volume reduction that produces when pipeline body 8 shakes simultaneously.
The working principle is as follows: when the sound-reducing and vibration-reducing pipeline damping vibration absorber is used, firstly, as shown in fig. 1-4, when the pipeline damping vibration absorber is required to be installed on the inner side of the pipeline body 8, the central axis of the connecting ring 1 and the central axis of the pipeline body 8 are positioned on the same horizontal plane, then the connecting ring 1 is pushed, because the rear surface of the limiting block 5 is inclined (the rear side of the limiting block 5 is inclined and belongs to the prior art, so that when the limiting block 5 contacts the pipeline body 8, the limiting block 5 supports the rod 4 to slide in the fixed frame 2, at the moment, the return spring 3 is compressed and deformed, because the appearance of the limiting block 5 is arc-shaped, the limiting blocks 5 correspond to the fixed frame 2 one by one, and the two sides of the limiting block 5 are inclined, when the limiting block 5 is positioned on the inner side of the pipeline body 8, under the action of the return spring 3 to restore, can make stopper 5 tightly support in the inside of pipeline body 8, when pipeline body 8 takes place vibrations, take place under the effect of deformation at reset spring 3, not only make pipeline damping bump leveller can not drop from pipeline body 8 in, also can carry out the shock attenuation to the junction simultaneously, then protected the normal use of pipeline damping bump leveller, the noise that pipeline body 8 during operation produced can be fallen to the piece 6 that inhales simultaneously, ventilation hole 7 and go-between 1 guarantee that the inside air current of pipeline body 8 circulates smoothly, this is exactly the theory of operation of this pipeline damping bump leveller that subtracts sound and shake, the content that does not make detailed description in this specification belongs to the known prior art of professional technical personnel in this field.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
