Technical Field

[0001] The utility model relates to the field of muffler barrels, in particular to a muffler barrel structure which is convenient for welding. Background Art

[0002] The muffler barrel is the part of the muffler, usually a tubular metal or ceramic shell that encloses the sound-absorbing material inside the muffler. The design and material of the muffler barrel can affect the performance of the muffler, such as reducing noise, reducing vibration and improving exhaust efficiency. Muffler barrels usually come in a variety of shapes and sizes to suit different types of engines and vehicles.

[0003] However, direct welding is often used when installing the barrel, and the welding process generates high temperature, which may cause the sound-absorbing material inside the barrel to be damaged or deformed, affecting the performance of the muffler. The welding process may also cause the barrel material to deteriorate or deform, affecting the appearance and structural strength of the muffler. At the same time, after the barrel is directly welded, the surface of the barrel needs to be polished, sprayed, etc., which increases the production cost and process.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment

[0034] Referring to Figures 1-5 , an embodiment provided by the present invention: a barrel body structure of a muffler that is convenient for welding, including a barrel body 1. One end of the outer wall of the barrel body 1 is fixedly provided with a front cover 11, and a front support plate 2 is fixedly provided on the side of the front cover 11 away from the barrel body 1. The other end of the outer wall of the barrel body 1 is fixedly provided with a rear cover 18, and a rear support plate 9 is fixedly provided at the rear end of the side of the rear cover 18 away from the barrel body 1. A bracket 8 is fixedly provided at the rear end of one side of the rear support plate 9. Auxiliary connection and buffering mechanisms 10 are fixedly provided on the front end side of one side of the front support plate 2 and the front end face of the bracket 8. By providing the auxiliary connection and buffering mechanisms 10, it is not necessary to perform welding and fixing operations on the body of the barrel body 1, reducing damages such as breakdown and breakage of the barrel body 1 caused by welding.

[0035] The auxiliary connection and buffering mechanism 10 includes a welding plate 1001, a fixed frame plate 1002, a connecting inner plate 1003, a connecting seat 1005, and two buffering springs 1006. The connecting inner plate 1003 is fixedly connected to the fixed frame plate 1002 through a fastening bolt 19. An air inlet pipe 5 is fixedly provided on one side of the front end face of the barrel body 1, and an exhaust pipe 7 is fixedly provided at the front end of one side of the rear cover 18.

[0036] Connect the air inlet pipe 5 to the exhaust end. After the internal structure of the barrel body 1 completes certain effects of silencing, filtering, etc., the exhaust is finally completed by the exhaust pipe 7. The internal structural processing can be based on an intake inner connection pipe 12 fixedly provided at the rear end of the air inlet pipe 5, an exhaust inner connection pipe 17 fixedly provided at one end of the exhaust pipe 7, a fish scale partition plate 13 fixedly provided on one side inside the barrel body 1, and a first inner partition plate 14 fixedly provided on the side of the fish scale partition plate 13. A second inner partition plate 16 is fixedly provided on the other side inside the barrel body 1. A middle pipe 15 is fixedly provided between the first inner partition plate 14 and the second inner partition plate 16. That is, when the gas enters and converges into the intake inner connection pipe 12, it will enter the barrel body 1, and after being discharged from the intake inner connection pipe 12, it enters the middle pipe 15 and is discharged again. Finally, it is discharged from the exhaust inner connection pipe 17 to the outlet end of the exhaust pipe 7. Multiple through holes are provided on the outer walls of the intake inner connection pipe 12, the exhaust inner connection pipe 17, and the middle pipe 15, so that the gas can be discharged from the outer through holes.

[0037] Specifically, according to the above embodiments, a transition sleeve 6 is fixedly arranged at the outer side near the front end of the intake pipe 5, and flanges 4 are fixedly arranged at the ends of the intake pipe 5 and the exhaust pipe 7 far from the cylinder body 1. A positioning column 3 is fixedly arranged at the outer side near the rear end of one side of the front support plate 2, and the rear support plate 9 is an L-shaped plate.

[0038] Specifically, according to the above embodiments, mounting holes 1004 are respectively formed on both sides of the upper end surface of the welding plate 1001. Mounting bolts are sleeved in the two mounting holes 1004. The fixed frame plate 1002 is fixedly arranged on one side of the front support plate 2 and a plurality of connecting holes are formed on the side close to the front support plate 2. The fastening bolt 19 is arranged in one of the plurality of connecting holes. The connecting inner plate 1003 is movably sleeved inside the fixed frame plate 1002. The connecting seat 1005 is fixedly arranged on the lower end surface of the welding plate 1001. The connecting seat 1005 is embedded in the connecting inner plate 1003 and two damping springs 1006 are fixedly arranged at the lower end of the connecting seat 1005.

[0039] That is, during use, after the welding plate 1001 is first assisted and fixed with screws, it is welded at the fixed position. At this time, the cylinder body 1 is installed. When it is necessary to change the height of the cylinder body 1, the height position of the fastening bolt 19 is adjusted. The cylinder body 1 is lifted upward to cause the fixed frame plate 1002 to move upward along the outer side of the connecting inner plate 1003, and after reaching the specified position, the fastening bolt 19 is twisted again to complete the position adjustment. At the same time, when the cylinder body 1 vibrates and moves up and down, the connecting inner plate 1003 will be pulled up and down back and forth. Since the connecting seat 1005 is slidably embedded inside the connecting inner plate 1003, it can only perform sliding operations in the up and down directions, so that the connecting seat 1005 and the lower damping spring 1006 cooperate to complete the buffering effect of the impact force of the up and down movement.

[0040] Working principle: During use, the welding plate 1001 can be first assisted and positioned with screws and then welded to fix the installation of the outer cylinder body 1. After the cylinder body 1 is fixed, when it is necessary to change the height of the cylinder body 1, the position of the fixed frame plate 1002 on the connecting inner plate 1003 can be changed to change its height. At the same time, when the cylinder body 1 moves up and down, the impact force generated by the up and down movement can be buffered under the action of the connecting seat 1005 and the damping spring 1006.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
