Problems solved by technology

[0005] 1. The outer diameters of the sound-absorbing sheet 3 and the sound-absorbing fiber body 4 installed in the inner diameter area 201 of different inner diameters are also different, not only the number of parts during manufacture is large, but also troublesome in material management and assembly
[0006] 2. The noise-absorbing fiber body 4 will deteriorate and fail after being used for a period of time, and must be replaced frequently

Abstract

The invention provides a silencing device for a pneumatic tool, comprising a shell and at least two silencing sheets which are arranged in the shell; the shell is provided with a circumferential wall and a plurality of embedding parts which are arranged on the circumferential wall at intervals along the circumferential direction and extend in the axial direction; the silencing sheets are provided with a plurality of silencing holes and at least a clamping part which is arranged on the external circumferential surface and is sheathed with the embedding part; furthermore, the silencing holes of two adjacent laminated silencing sheets are arranged in a staggered way; therefore, as the silencing holes of the two adjacent laminated silencing sheets are arranged in the staggered way, the airway is circuitous, the airflow speed and the pressure are greatly reduced, thus lowering the volume.

Description

technical field [0001] The invention relates to a pneumatic tool, in particular to a noise reduction device of the pneumatic tool. Background technique [0002] As shown in Figure 1, there is an existing sound-absorbing device for pneumatic tools, which is installed on a body 1, and the sound-absorbing device includes an end body 2, a plurality of sound-absorbing sheets 3 installed inside the end body 2, and a plurality of sets The sound-absorbing fiber body 4 on one side of the sound-absorbing sheet 3 . The end body 1 is provided with a plurality of inner diameter areas 201 with different apertures. The sound-absorbing sheet 3 has a plurality of sound-absorbing holes 301. The sound-absorbing fiber body 4 is stacked with the sound-absorbing sheet 3 and installed on the inner diameters of different apertures. District 201. [0003] When the high-pressure gas inside the pneumatic tool enters the sound-absorbing device, the sound-absorbing hole 301 of the sound-absorbing shee...
