[0019] Example

[0020] Depend on Figure 1-3 Provided is a noise reduction accessory for a pneumatic motor, comprising a mounting plate 1 and a pneumatic motor body 2;

[0021] Four groups of buffer components 3 are installed at the lower end of the mounting plate 1 and the four groups of buffer components 3 are distributed in a rectangular shape;

[0022] The buffer assembly 3 includes a support member 30, and one side of the buffer assembly 3 is rotatably connected with two first connecting plates 31 and two second connecting plates 32 through a rotating shaft. The outer sides of the two first connecting plates 31 are each equipped with a first connecting member 311, and the outer sides of the two second connecting plates 32 are each equipped with a second connecting member 321. A hydraulic rod 33 is rotatably connected between the first connecting member 311 and the second connecting member 321 on the same side, and a compression spring 34 is sleeved on the outside of the hydraulic rod 33. A positioning plate 35 is rotatably connected between the other ends of the two first connecting plates 31 and the two second connecting plates 32 through a rotating shaft, and a connecting block 36 is installed on one side of the positioning plate 35. A groove is provided on one side of the connecting block 36, and a third connecting rod 361 is penetrated through the groove, and a support seat 37 is installed on the outside of the third connecting rod 361.

[0023] In this embodiment, after the pneumatic motor body 2 is installed on the mounting plate 1 through the mutual cooperation between the components in the four groups of buffer assemblies 3, when the pneumatic motor body 2 generates vibration and impact, the impact force and vibration cause the support seat 37 to move downward, thereby driving the set connecting block 36, so that the connecting block 36 drives the two connected first connecting plates 31 and the second connecting plate 32, and squeezes the set hydraulic rod 33 and the compression spring 34. The set hydraulic rod 33 can effectively buffer the external impact and vibration. The set compression spring 34 has its elastic characteristics that can absorb and disperse the impact and vibration, and absorb the received energy, and cooperate with the set base 302 made of polyurethane material to finally reduce the impact force and vibration, effectively reduce the vibration conduction generated by the pneumatic motor body 2, reduce the spread of noise, thereby improving the working environment, and improving the work comfort and production efficiency of the staff.

[0024] Specifically, refer to Figure 1-3 The lower end of the support member 30 is rotatably connected to two bases 302 through a first connecting rod 301.

[0025] In this embodiment, the base 302 is made of polyurethane material, which is a polymer compound with excellent stability, resilience, mechanical properties, and shock resistance. When impacted, it deforms to absorb the generated energy, thereby improving the cushioning effect.

[0026] Specifically, refer to Figure 1-2 The upper end surface of the mounting plate 1 is provided with a plurality of mounting holes 11 in a rectangular array.

[0027] In this embodiment, by arranging a plurality of mounting holes 11 at the upper end of the mounting plate 1, the mounting plate 1 has greater flexibility and adjustability, and the pneumatic motor body 2 can be installed by rotating it to different positions and angles as required to meet different installation requirements, thereby saving installation time and labor costs.

[0028] Specifically, refer to Figure 1-2 The upper end surface of the mounting plate 1 is also provided with anti-slip textures.

[0029] In this embodiment, by providing anti-slip texture on the mounting plate 1, the friction between the mounting plate 1 and the pneumatic motor body 2 can be increased, thereby improving the firmness of the installation and preventing the pneumatic motor body 2 from moving and shaking during operation, thereby indirectly reducing the noise caused by loose installation and improving the overall noise reduction effect of the device.

[0030] The utility model of noise reduction accessories for pneumatic motors:

[0031] During actual use, through the several mounting holes 11 set on the mounting plate 1, the user can easily install the pneumatic motor body 2 through bolts. When the pneumatic motor body 2 is started, the vibration and impact generated by the pneumatic motor body 2 itself squeeze the four groups of pneumatic motor bodies 2 downward, and drive the support seat 37 in the pneumatic motor body 2, so that the support seat 37 is downward, thereby driving the connecting block 36, so that the connecting block 36 drives the two connected first connecting plates 31 and the second connecting plate 32, and squeezes the hydraulic rod 33 and the compression spring 34. The hydraulic rod 33 can effectively buffer the external impact and vibration. The elastic characteristics of the compression spring 34 can absorb and disperse the impact and vibration, and absorb the received energy, and cooperate with the base 302 made of polyurethane material to finally reduce the impact force and vibration, and effectively reduce the vibration conduction generated by the pneumatic motor body 2.
