With the gradual increase in the horsepower of steam turbines, their exhaust emissions are also increasing, which in turn leads to higher than standard noise. In this case, the industry has gradually developed a kind of silencer that can be connected to the (four) tube, which can effectively reduce the volume of the voice. For example, the new case of the "External Exhaust of the Exhaust Pipe" in China's Announcement f Μ 296916 The utility model mainly comprises a muffler tube and a positioning cover. The muffler has a hollow tube shape and can be inserted into the exhaust pipe of the vehicle. The muffler pipe has a coupling seat at one end, and a screw hole is arranged on the side wall of the coupling seat. The root ring of the positioning cover is equivalent to the outer diameter of the tail end of the exhaust pipe and can be combined and fixed to each other, and is enlarged to form a tail cover for the joint to be placed, and the bottom surface of the tail cover is provided with H, A screw hole that corresponds to the joint of the muffler tube. When in use, the positioning cover is sleeved on the outside of the exhaust pipe of the vehicle, and is combined and fixed. 'The same day silencer pipe is inserted into the exhaust tail pipe, and the fixed seat completely resists the exhaust tail pipe. The outlet end is inserted into the through hole of the positioning cover by a bolt, and is screwed to the screw hole on the joint of the muffler tube. The exhaust end of the exhaust pipe is externally connected with a silencer, which can provide the effect of noise reduction. However, as described above, the combination of the muffler tube and the positioning cover, M356798 is achieved by forming a corresponding perforation and a screw hole on one side thereof, and the screwing method is used; The muffler tube is easily subjected to the torque generated by the exhaust gas flow and pivots relative to the positioning cover, resulting in local stress concentration at the screw school and structural sway and is not stable, and is liable to cause damage or fall off. [New content] The main purpose of this creation is to provide a positive fixed exhaust pipe silencer that provides a firm coupling to the exhaust pipe. In order to achieve the above purpose, the forward fixed exhaust pipe silencer of the present invention mainly comprises a muffler tube and a certain cloth g. gane and a position cover, wherein the muffler tube is hollow tubularly shaped to be inserted into the vehicle row. Within the trachea, the outer end edge is formed with a plurality of perforations; the positioning cover end can be sleeved at the end of the exhaust pipe, and the other end is formed with an opening σ ' for the muffling pipe to pass through and the opening edge of the opening The plurality of keyholes corresponding to the perforations. 蕤y has a plurality of pupils, whereby a plurality of fixing members can be fixed in the perforations and the keyholes, I: Xiao Li & and lock, ^ 7 4 a tube Relatively positioned on the positioning pan. Wherein, the fixing member fixes the muffler tube in a forward manner: the cover member, that is, the fixing member flattens the axis of the muffler tube to the muffler tube. Clever lock--v π-symbol' mouth-knife function, when the waste pain silencer tube applies external force, the silencer tube will be firmly combined on the positioning cover'--there will be sloshing or local concentration of stress, so : Do not be bad or fall off. Exemption of M356798 [Embodiment] Please refer to the first, second and third figures. An exhaust pipe includes an intake end (10) and an air outlet end (11). The intake end (1〇) is connected. In the body of a car or a locomotive, the outlet end (U) is formed with an air outlet for exhausting the exhaust gas. The forward fixed exhaust pipe silencer of the present invention comprises a sound absorbing camp (2), a positioning cover (3) and a plurality of fixing members (4), wherein: the muffling pipe (2) has a hollow cylindrical shape, and one of the inner portions The end can be inserted into the air outlet of the exhaust camp (1), and an outer end edge of the outer peripheral edge is formed with a flange (20), the dog edge (20) is formed with a plurality of perforations (21) spaced around; The positioning cover (3) has a truncated cone shape, and has a set portion (3〇) at one end thereof, and the inner diameter of the sleeve portion (30) matches the outer diameter of the tail end of the exhaust pipe (丨). Nested at the end of the exhaust pipe (1); the other end is formed with an opening (31) through which the muffling pipe (2) passes, and the opening of the opening (31) is formed with a corresponding hole (21) a plurality of keyholes (32); the plurality of fixing members (4) are inserted into and locked in the through holes (21) and the keyholes (32) to position the muffler tube (2) relative to the positioning cover (3) Upper. Wherein the fixing member (4) fixes the muffling tube (2) to the clamping cover (3) in a forward manner, that is, the fixing member (4) has an axis parallel to the axis of the muffler (2) Lock the silencer tube (2) in a way. Thereby, the silencing tube (2) can be subjected to a uniform bonding force, and when the exhaust gas flow exerts an external force on the silencing tube (2), the silencing tube (2) will be firmly coupled to the clamp cover (3) without There are sloshing or localized stresses that produce 'and thus avoid damage or detachment.
