Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a muffler fixing mechanism. Background Art

[0002] Muffler refers to a noise reduction device that can be used to reduce the noise in the air flow pipe by using pipes and elbows with sound-absorbing lining or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance, so as to attenuate or reflect the noise in the pipe. The former is called resistive muffler, the latter is called reactive muffler, and there are also impedance composite mufflers.

[0003] When personnel actually use the silencer, they need to ensure the stability of the silencer. At this time, they need to use it in conjunction with a fixing mechanism. When personnel encounter a flange with a thicker size requirement, they need to use it with a longer bolt, which increases the number of tools that personnel need to carry and brings a burden to personnel. A silencer fixing mechanism is hereby proposed. Utility Model Content

[0012] The utility model has at least the following beneficial effects:

[0013] When in use, personnel can adjust the length of the screw according to the thickness of the flange to be connected. When the thickness of the flange is thicker, the personnel rotates the hexagonal column to make the screw rotate, and the screw sleeve will move accordingly, thereby driving the ring to move downward, and then causing several screws to move downward, and adapt to the thicker flange for installation. The muffler body is fixed and limited by the nut and the screw, thereby completing the fixation of the muffler body. Through the structural design, when personnel need to connect the muffler body with the pipe, when the pipe needs to use a thicker flange, it can be quickly adjusted to adapt to the thick flange for use, and the adjustment operation process does not require personnel to perform more cumbersome operations, ensuring that the muffler body can always be stably connected.

The length is adjusted. When the thickness of the flange 4 is thicker, the personnel rotates the hexagonal column 11 to rotate the screw rod 9, and the screw sleeve 8 will move accordingly, thereby driving the ring 10 to move downward, and then causing several screw rods 7 to move downward, and adapt to the thicker flange 4 for installation. The nut is used to cooperate with the screw rod 7 for fixing and limiting, thereby completing the fixation of the muffler body 1.

When the thickness of the flange 4 is thicker, the personnel rotate the hexagonal column 11 to rotate the screw 9, and the screw sleeve 8 will move accordingly, thereby driving the ring 10 to move downward, and then causing several screws 7 to move downward, and adapt to the thicker flange 4 for installation. The nut is used to cooperate with the screw 7 for fixing and limiting, thereby completing the fixation of the muffler body 1. The setting of the slider 6 and the slide groove 5 prevents the screw sleeve 8 from rotating with the screw 9. The setting of the hexagonal column 11 makes it convenient for personnel to tighten The movable screw 9 rotates, and through the setting of the screw 7, the nut can be used to stably limit the flange 4. Through the setting of the outer frame 3, the operation of its internal structure is protected from external forces. Through the setting of the ring 10, a stable supporting force is provided for several screws 7.
