Abstract
The utility model discloses a kind of sound gobos with reinforcement structure, it includes oval clapboard body, there is the location hole being used for through positioning hush pipe in the clapboard body, and the clapboard body periphery has flange, the flange includes the small arc flange in the oval long axis both ends, the big arc flange in the oval short axle both ends and connects transition flange between the big arc flange, small arc flange, wherein, the height of the big arc flange is higher than the height of the small arc flange.Utility model design is reasonable, improves the use structural strength and service life of entire muffler, very useful.
Description
Technical field
The utility model is related to a kind of sound gobo with reinforcement structure and the mufflers containing the sound gobo, belong to and disappear
Sound device technical field.
Background technology
It is well known that muffler, be prevent sound ship and allow air-flow by a kind of device, be to eliminate air force
The important measures of property noise.Its mainly be mounted on air powered equipment for example air blower, air compressor machine, boiler exhaust mouth, generator,
The device of reduction noise on the gas channel of the larger equipment of the exhaust outlet noises such as water pump or in inlet and exhaust system.
And be typically all that multiple chambers are separated by sound gobo in muffler, then with hush pipe progress air-flow is coordinated to walk
To, and then realize and decayed step by step to the noise in air-flow.Meanwhile the sound gobo also acts as positioning and strengthens each hush pipe
And the function of entire muffler shell.Then existing sound gobo is only a usual metal plate punching plate, without any designing points.
The content of the invention
Shortcoming in for the above-mentioned prior art, the utility model are intended to provide a kind of noise reduction with reinforcement structure
Partition plate and the muffler containing the sound gobo, design is reasonable, improves the use structural strength of entire muffler and using the longevity
Life, it is very useful.
To achieve these goals, the technical solution of the utility model：A kind of sound gobo with reinforcement structure, bag
Oval clapboard body is included, there is the location hole being used for through positioning hush pipe, and the clapboard body in the clapboard body
Periphery has flange, and the flange includes the small arc flange in the oval long axis both ends, in the oval short axle
The big arc flange at both ends and transition flange between the big arc flange, small arc flange is connected, wherein, the height of the big arc flange
Degree is higher than the height of the small arc flange.
Further, the big arc flange is in the trapezoidal structure of projection on the vertical plane where the oval long axis.
Further, the small arc flange is rectangle knot in the projection on the vertical plane where the oval short axle
Structure.
Further, there is the hole flanging set along its center axis direction, and the hole flanging and institute on the location hole
The setting direction for stating flange is opposite.
Further, if having dry gas stream via in the clapboard body.
A kind of muffler, including at least one foregoing sound gobo with reinforcement structure.
The beneficial effects of the utility model：Design is reasonable, by increasing the arc flange at sound gobo short axle both ends, then matches somebody with somebody
The hole flanging and hush pipe for closing positioning hush pipe form entire muffler structure, improve the use structural strength of entire muffler
And service life, it is very useful.
Description of the drawings
Fig. 1 is the floor map of the utility model；
Fig. 2 is along the sectional view of line A-A in Fig. 1.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
A kind of sound gobo as shown in Figure 1 and Figure 2 with reinforcement structure, should including oval clapboard body 10
There is the location hole being used for through positioning hush pipe, and 10 periphery of clapboard body has flange 11, flange in clapboard body 10
11 include the small arc flange 13 in oval long axis both ends, the big arc flange 12 in oval short axle both ends and connection should
Transition flange between big arc flange 12, small arc flange 13, wherein, the height of big arc flange 12 is higher than the height of small arc flange 13
Degree.
The utility model is by increasing the arc flange at sound gobo short axle both ends, to realize to muffler shell more
Stable position also avoids the deformation of entire suppressor case.Specifically, big arc flange 12 is in hanging down where oval long axis
The trapezoidal structure of projection faced directly.And small arc flange 13 is in rectangular in the projection on the vertical plane where the oval short axle
Shape structure.It is saving on the basis of material, is adding positioning intensity of the sound gobo to muffler shell and hush pipe.Certainly
Such as without considering cost problem, 11 height of flange of entire sound gobo can be increased.
There is the hole flanging 15 set along its center axis direction, and the setting of the hole flanging 15 and flange 11 on location hole
It is integrally assembled in conjunction with muffler shell and hush pipe on the contrary, its cooperation flange 11, strengthens the use of entire muffler in direction
Structural strength.Finally, in order to ensure the normal work of muffler, if having dry gas stream via 16 in clapboard body 10.Simultaneously
Also there is the groove 14 set along its short axle axis direction at oval short axle both ends, for air-flow to be coordinated to pass through.
The utility model also discloses a kind of muffler, including at least one foregoing disappearing with reinforcement structure
Sound partition plate.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is set forth the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in specific embodiment and application range, in conclusion this specification content should not be construed as
Limitation to the utility model.
