[0023] In the following, only certain exemplary embodiments are briefly described to make the objects, features, and advantages of the present invention more readily apparent. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figures 1 to 3 As shown, the utility model provides a silencer coupling, comprising: a first connecting member 1; a plurality of first positioning claws 11 are provided on the first connecting member 1; a second connecting member 2; the first connecting member 1 is detachably provided at one end of the second connecting member 2; a third connecting member 3; a plurality of second positioning claws 31 are provided on the third connecting member 3; the third connecting member 3 is detachably provided at the other end of the second connecting member 2.

[0027] In this embodiment, the coupling is composed of a first connecting member 1, a second connecting member 2 and a third connecting member 3 which are inlaid with each other, wherein the first connecting member 1 is connected to the second connecting member 2 in combination through a circumferentially arranged first positioning claw 11, and the third connecting member 3 is connected to the second connecting member 2 in combination through a circumferentially arranged second positioning claw 31, and the second connecting member 2 is made of soft rubber material, so that the first positioning claw 11 and the second positioning claw 31 can form a buffer area on the second connecting member 2, thereby absorbing the vibration generated by the first connecting member 1 and the third connecting member 3 when the coupling is working, so that the coupling can evenly distribute pressure during rotation, and can effectively absorb mechanical vibration and noise, thereby achieving the grinder silencing and buffering shock absorption effect.

[0028] Furthermore, a first mounting groove 4 is provided on the inner side of the upper end of the second connecting member 2; the first positioning claw 11 is detachably provided in the first mounting groove 4. A plurality of second mounting grooves 5 are circumferentially provided on the outer side of the lower end of the second connecting member 2; the second positioning claw 31 is detachably provided in the second mounting groove 5.

[0029] In this embodiment, the first mounting groove 4 is arranged on the inner side of the upper end of the second connecting member 2, and the second mounting groove 5 is arranged on the outer side of the lower end of the second connecting member 2. The positions of the first mounting groove 4 and the second mounting groove 5 are staggered with each other, so that the first mounting groove 4 and the second mounting groove 5 are arranged in a mirror-symmetrical equilateral triangle (see Figure 3), the equilateral triangle distribution can effectively disperse the stress, and the structure is more stable, ensuring that each first positioning claw 11 and the second positioning claw 31 in the first mounting groove 4 and the second mounting groove 5 can be evenly stressed during operation, reducing the vibration caused by eccentricity.

[0030] Furthermore, the first connecting member 1 and the third connecting member 3 are structural members made of nylon material; and the second connecting member 2 is a structural member made of TPE material.

[0031] In this embodiment, the first connecting member 1 and the third connecting member 3 are made of hard rubber (nylon material), which ensures the overall rigidity and wear resistance of the coupling; the second connecting member 2 between the first connecting member 1 and the third connecting member 3 is made of soft rubber (TPE material), forming an elastic buffer area between the two to further absorb vibration and noise.

[0032] Furthermore, three first positioning claws 11 are equidistantly arranged on the first connecting member 1 in the circumferential direction; the cross-sectional shape of the first positioning claws 11 is an isosceles trapezoid.

[0033] In this embodiment, the three first positioning claws 11 on the first connecting member 1 are arranged in a circumferentially equidistant manner to form a three-claw structure, and the distribution thereof is arranged in an equilateral triangle. The three first positioning claws 11 are all inserted into the first mounting groove 4 (see Figure 2 and Figure 3 ), the three-claw design can effectively disperse stress, and the structure is more stable, ensuring that each first positioning claw 11 can be evenly stressed during operation and reducing vibration caused by eccentricity.

[0034] Furthermore, three second positioning claws 31 are equidistantly provided on the third connecting member 3 in the circumferential direction; the cross-section of the second positioning claws 31 is triangular.

[0035] In this embodiment, the three second positioning claws 31 on the third connecting member 3 are also arranged in a circumferentially equidistant manner to form a three-claw structure, and the distribution thereof is an equilateral triangle. The three second positioning claws 31 are all clamped on the second mounting groove 5 (see Figure 2 and Figure 3 ), the three-claw design can effectively disperse stress, and the structure is more stable, ensuring that each second positioning claw 31 can be evenly stressed during operation and reducing vibration caused by eccentricity.

[0036] Furthermore, the first connecting member 1 is provided with a first connecting hole 6 which can be connected to the grinder motor shaft 8. The third connecting member 3 is provided with a second connecting hole 7 which can be connected to the grinder grinding shaft 9.

[0037] In this embodiment, a first connecting hole 6 is provided on the first connecting member 1, and a second connecting hole 7 is provided on the third connecting member 3. When the coupling is installed in the grinder, the first connecting hole 6 is connected to the grinder motor shaft 8, and the second connecting hole 7 is connected to the grinder grinding shaft 9, thereby achieving a coupling effect between the motor shaft 8 and the grinding shaft 9 through the coupling.

[0038] Furthermore, a through hole is provided through the second connecting member 2 ; the through hole is located on the same straight line as the first connecting hole 6 and the second connecting hole 7 .

[0039] In this embodiment, a through hole is provided on the second connecting member 2, and the inner cross-sectional shape of the through hole is the same as that of the first connecting hole 6 and the second connecting hole 7, so that when the coupling is respectively connected to the grinder motor shaft 8 and the grinder grinding shaft 9, the second connecting member 2 will not interfere with the above two shafts.

[0040] Example 2

The silencer coupling can be used in various different grinders. The silencer coupling has all the technical effects in Example 1. Therefore, when the silencer coupling is used in the grinder, it also has the same technical effects, which will not be repeated here.
