Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The present invention is not limited to the embodiments.

FIG. 1 is a partially exploded perspective view for explaining the present invention, FIG. 2 is a partially enlarged cross-sectional view of a coupled state according to FIG. 1, and FIG. 3 is a cross-sectional view of a state in which the present invention is installed in a pipe.

As shown in the figure, each of the engaging holes 112 of the front and rear plates 110 and 110A of the sound-absorbing silencer 100, which is installed in various piping P such as air- (1) for fixing a plurality of other tubes (120) into which respective ends are inserted.

The sound absorbing silencer 100 includes front and rear plates 110 and 110A having a plurality of coupling holes 112 and a plurality of coupling holes 112 formed in the front and rear plates 110 and 110A, A housing body 130 provided to cover the outside of the front and rear plates 110 and 110A and the outside tube 120 and a plurality of tappets And a sound absorbing material (140) interposed between the cavity (120) and absorbing noise emitted from the cavity of the cavity (120).

The present invention is to provide a sound absorbing silencer which can firmly and tightly be fixed by simple assembly rather than fixing a plurality of other pipes through welding, riveting, or bolting.

The fixing device 1 according to the present invention is installed in each of the engagement holes 112 of the entire plate 110 so as to minimize the resistance of the gas passing through the tip of the other hole 120 Each fixed cap 10 fixed to the other pipe 120 through at least one insertion hole 12 formed in the front plate 110 after covering the front end of the front plate 120; And an enlarged tube fixing part 20 for expanding and fixing the rear end of the other tube 120 inserted into and protruded from each of the fitting holes 112 of the rear plate 110A.

Each of the fixed caps 10 includes a cap portion 14 that covers and covers the tip of the other capillary tube 120 and a cap 12 that extends from the cap portion 14 and is inserted into the insertion hole 12, And a plurality of fixing pieces 16 which are inserted and fixed to the base plate 16. It is preferable that the cap portion 14 surrounding the tip of the other pipe 120 is curved so as to minimize friction when the gas collides with the cap portion.

Accordingly, it is an object of the present invention to provide a method and apparatus for fixing a plurality of other pipes fixedly coupled to a front plate and a rear plate through a simple and convenient assembly process, not by fixing them through a complicated and complicated process such as welding, riveting, .

That is, when the tip of the other tube is fixed to the entire plate, the tip of the other tube projected from the coupling hole of the front plate is covered with the cap portion of the fixed cap, and the remnant fixed piece is passed through the insertion hole formed in the entire plate The tip of the other pipe can be easily fixed to the entire plate by pushing it into the hole of the other pipe.

Then, the rear end of the other pipe projecting to the coupling hole of the rear plate is also simply engaged and fixed by expanding the projecting portion by a known expansion method.

In addition, instead of fixing the other pipe to the front plate by the fixing cap, the rear end of the other pipe may be firstly expanded and fixed to the rear plate, and then the front end of the other pipe may be fixed to the front plate by the fixing cap .

In this way, according to the present invention, a method of coupling and fixing the respective holes to the respective coupling holes formed on the front and rear plates is not fixed through welding, riveting, or bolting, So that excellent assembling property can be obtained.

Further, since the coupling is fixed by assembling, the assembling time can be also shortened within a short time.

Particularly, according to the present invention, it is not necessary to replace the entire silencer when any one of the other tubes is deformed or an error occurs, but only the corresponding other tubes can be separated from the front and rear plates, .

Accordingly, the present invention is not limited to fixing a plurality of other pipes constituting the sound-absorbing silencer by a considerably cumbersome and inconvenient work process such as welding, riveting, or bolting in a fixed state, but can be quickly and simply combined It is possible to maximize the efficiency of assembling.

Furthermore, even if the deformation of the other pipe is damaged during the use process after assembly, it is not necessary to replace the entire silencer, and it is possible to simply replace the deformed pipe or the other pipe of the damaged part, It also has a high advantage.

4 is a partially exploded perspective view for explaining another embodiment of the present invention.

As shown in the drawings, in the above-described configuration, the tip of the other pipe can be easily coupled and fixed in the process of engaging and fixing the tip of the other pipe with the respective fixed caps on the entire plate.

That is, the above-described fixed caps are not individually formed, but are formed in the form of a single module 10A or a plurality of modules in such a manner that the fixed caps 10 are connected to each other during a press operation known in the art.

In other words, each fixed cap 10 is connected to a connecting rod 10Aa 'formed at a position corresponding to each other, or connected to a rim of the fixed cap 10 together with a connecting rod 10Aa' by a connecting rod 10Aa ' The connection frame 10Aa formed of a frame (not shown) is formed as one module instead of a separate fixed cap, thereby making it possible to more easily perform the engagement and fixing operation of the fixed cap. At this time, the module may be formed as one module corresponding to the entire plate, or may be formed into a plurality of divided modules.

Accordingly, it is possible to use the connecting caps of the connecting frame in a state where the respective fixed caps are connected to each other, thereby making it possible to assemble the operator more easily by fixing the tip of the other pipe. It has the advantage of being able to do.

5 is a partially exploded perspective view and a cross-sectional view for explaining another embodiment of the present invention.

As shown in the drawings, in the above-described configuration, when the gas is introduced into the other pipe of the sound-absorbing silencer, the gas is introduced into the muffler more efficiently while colliding with the minimum.

The entire plate 110 between the fixed cap 10 and the fixed cap 10 includes respective conductors 30 that are provided to induce a flow of gas to the respective perforated pipe 120.

The guide 30 includes a guide body 32 in the form of a cone and an engaging and securing piece 34 which is inserted into and fixed to a plurality of through holes 34 formed in the front plate 110 at the foot of the guide body 32 36).

In other words, the gas flowing into the pipe P directly collides with the entire plate 110 between the other pipe 120 and the other pipe 120 and flows smoothly into the other pipe 120 without friction .

That is, when the gas introduced into the pipe through the entire pipe between the other pipes collides without being introduced into the other pipe, the noise reduction efficiency is reduced when another collision occurs with the gas flowing into the other pipe as the vortex occurs. Accordingly, in order to prevent such a phenomenon, the gas is guided to the side of the other pipe naturally by providing the dielectric on the surface of the entire plate between the other pipes.

The majority of the gas introduced into the piping and flowing into the front plate is introduced into the other piping, and the gas flowing into the entire plate between the other piping is guided to the other piping without collision by the derivative, The noise included in the introduced gas is released through the pores of the other pipe, and is canceled by the sound absorbing material, so that the noise removing efficiency is further enhanced.

6 is a partial cross-sectional view for explaining another embodiment of the present invention.

As shown in the drawings, in the process of removing the noise by the sound-absorbing silencer in the pipe, the noise can be removed in advance before being introduced into the sound-absorbing silencer, so that the noise cancellation efficiency can be further increased.

The noise reduction member (40) further includes a noise reduction member (40) provided inside the front pipe (P) of the sound absorbing silencer (100) to uniformly distribute the introduced gas while canceling the noise first, A support plane portion 44 formed by bending the outer side of the guide portion 42 and a guide portion 42 formed on the outer side of the guide portion 42, And a sound absorbing material (46) provided on the rear side of the piercer between the support plane portion (44).

The guide portion 42 is formed in the shape of a circular cone, a square, or a polygonal shape so that the gas introduced from the front is uniformly dispersed.

Accordingly, the gas introduced into the pipe is first dispersed evenly through the guide portion of the noise reduction member, and is moved toward the sound absorption silencer through the holes formed in the guide portion and the support plane portion. At this time, a part of the noise included in the gas is canceled by the sound absorbing material provided on the rear side of the guide and the supporting plane portion, so that noise smaller than the noise included in the gas initially introduced into the sound absorbing silencer is transmitted.

Therefore, the sound absorbing silencer has a condition that can more effectively remove the noise, thereby providing a condition for maximizing the noise removing efficiency.

As a result, noise can be removed from the sound-absorbing silencer after the noise is primarily removed by the noise-reducing member that partially diffuses the gas flowing into the front pipe in which the sound-absorbing silencer is located, , The noise cancellation efficiency is further increased, and the noise transmitted through the pipe can be originally blocked.
