Description
Technical field
Vehicle maintenance service technical field is the utility model is related to, more particularly to a kind of deformable vehicle tail gas disappears
Sound device.
Background technology
Mobile muffler, is mainly used for reducing noise caused by the engine work of motor vehicle, its principle is automobile row
Tracheae is made of two different pipelines of length, the two pipelines first separate to cross again, due to the length difference of the two pipelines
The half of the wavelength of the sound wave sent equal to automobile so that two row sound waves are interfered in superposition and cancelled out each other and decrease sound
By force, the sound for making to be transmitted through reduces, so as to play the effect of noise reduction.
Existing muffler structure is fixed, very inconvenient when mounted since bottom of car installation space is limited.
Utility model content
The purpose of this utility model is to fix the shortcomings that being not easy installation and maintenance to solve existing muffler structure, and is carried
A kind of deformable vehicle tail gas muffler gone out.
To achieve these goals, the utility model employs following technical solution：
Design a kind of deformable vehicle tail gas muffler, including several unit housings, the unit housings bag
Cylindrical connector, axis pin and connecting tube are included, the connecting tube cross section is rectangle, and one end and the cylinder of the connecting tube connect
Two end faces of connector are connected by axis pin, and the side of the cylinder connector is provided with through hole, the axis and circle of the through hole
The axis of cylindricality connector is vertical, and two surfaces up and down of the both ends inner wall of the connecting tube are equipped with one layer of sealing rubber pad, institute
State the both ends inner wall of connecting tube and parallel two surfaces of cylinder connection end surface be equipped with one layer of foam, the connecting tube outside
Portion is arranged with several elastic sound absorbers.
Preferably, the elastic sound absorber includes rubber ring and circular sponge, and the rubber ring sleeve is located at connecting tube
On, the annular shape sponge is pasted on the inner peripheral surface of rubber ring.
Preferably, the middle part cross-sectional area of the connecting tube is less than both ends cross-sectional area, and the middle part of connecting tube and two
The joint face at end uses circular arc camber transition.
Preferably, for the unit housings, between the medium and small line of the connection end surfaces and cylindrical connector
Minimum range be more than three centimetres.
Preferably, the cylindrical connector and connection tube outer surface are equipped with one layer of acoustic paint
The utility model proposes a kind of deformable vehicle tail gas muffler, beneficial effect is：There is provided can
The muffler shell formed with the unit housings of splicing, can be rotated between unit housings in certain angle, so installed
When it is easily operated, easy to adjust, when disassembled for transport, is also more convenient.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of deformable vehicle tail gas muffler unit housings connection structure
Schematic diagram；
Fig. 2 be the utility model proposes a kind of deformable vehicle tail gas muffler Fig. 1 A at sectional view.
In figure：Cylindrical connector 1, axis pin 2, connecting tube 3,4, sealing rubber pad 5, rubber ring 6, ring-type sponge 7, through hole
8th, elastic sound absorber 9, foam 10.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of deformable vehicle tail gas muffler, including several unit housings 4, unit housings
4 include cylindrical connector 1, axis pin 2 and connecting tube 3, and 3 cross section of connecting tube is rectangle, and one end and the cylinder of connecting tube 3 connect
Two end faces of connector 1 are connected by axis pin 2, and the side of cylindrical connector 1 is provided with through hole 8, axis and the cylinder of through hole 8
The axis of connector 1 is vertical, and two surfaces up and down of the both ends inner wall of connecting tube 3 are equipped with one layer of sealing rubber pad 5, connecting tube 3
Both ends inner wall two surfaces parallel with cylindrical 1 end face of connector be equipped with one layer of foam 10, the outer cover of connecting tube 3 is equipped with
Several elastic sound absorbers 9.
Elastic sound absorber 9 includes rubber ring 6 and circular sponge 7, and rubber ring 6 is set in connecting tube 3, circular sea
The inner peripheral surface that silk floss 7 is pasted on rubber ring 6, circular sponge 7 can play the role of certain noise elimination, and rubber ring 6 can be with
Prevent external impact, cause device to damage.
The middle part cross-sectional area of connecting tube 3 is less than both ends cross-sectional area, and the joint face at the middle part of connecting tube 3 and both ends
Using circular arc camber transition, such shape is more beautiful.
For a unit housings 4, the minimum range between the medium and small line of 3 end face of connecting tube and cylindrical connector 1 is big
In three centimetres, such connecting tube 3 can be rotated around cylindrical connector 1 in certain angle, easy to adjust.
Cylindrical connector 1 and 3 outer surface of connecting tube are equipped with one layer of acoustic paint, and acoustic paint can be with the whole of intensifier
Body acoustic attenuation performance.
When the utility model is used, by each unit housings 4, by corresponding connecting tube 3 and cylindrical connector 1 according to
