The first sound insulation layer 3 is attached to the surface of the upper cover 1, and the second sound insulation layer 4 is attached to the surface of the lower cover 2.

According to the coupler protection cover provided by the embodiment of the utility model, the upper cover body 1 and the lower cover body 2 are connected to form the protection cavity for accommodating the coupler, and the upper cover body 1 and the lower cover body 2 jointly realize shielding and protection of the coupler. The first sound insulation layer 3 and the second sound insulation layer 4 are respectively attached to the surfaces of the upper cover body 1 and the lower cover body 2, so that noise generated by high-speed rotation of the coupling can be effectively isolated. Meanwhile, the natural frequency of the combination of the first sound insulation layer 3 and the upper cover body 1 and the natural frequency of the combination of the second sound insulation layer 4 and the lower cover body 2 are not basically the same as the frequency of the high-speed rotation of the coupler, so that the resonance of the upper cover body 1 and the lower cover body 2 is effectively avoided, and the noise reduction effect of the coupler protective cover is further improved.

The first sound insulation layer 3 and the second sound insulation layer 4 may be sound insulation foam, and the combination of the first sound insulation layer 3 and the second sound insulation layer 4 substantially completely covers the protection cavity, thereby more reliably realizing the blocking of noise generated when the coupling rotates at a high speed.

Therefore, under the limit of the first pressing plate 5 and the second pressing plate, the first sound insulation layer 3 and the second sound insulation layer 4 are not easy to loosen and separate, and the sound insulation effect of the first sound insulation layer 3 and the second sound insulation layer 4 is effectively guaranteed.

In some embodiments, the first platen 5 and/or the second platen are located within the protective chamber and are discretely distributed with a plurality of through holes.

At this time, the first sound insulation layer 3 and the second sound insulation layer 4 are fully communicated with the protection cavity through a plurality of through holes, in other words, the area of the first sound insulation layer 3 and the second sound insulation layer 4 communicated with the protection cavity is larger, so that the absorption of sound emitted by the coupler can be more fully realized, and the noise reduction performance of the coupler protective cover is further ensured.

Specifically, the through holes can be formed on the first pressing plate 5 and the second pressing plate in a stamping mode, and a plurality of through holes are uniformly distributed on the first pressing plate 5 and the second pressing plate.

As shown in fig. 2, the second pressing plate may be disposed outside the protective chamber, that is, the second sound insulation layer 4 is attached to the outer surface of the lower cover 2, and no through hole may be punched in the second pressing plate.

In some embodiments, as shown in fig. 5, a first weld nut 51 and a second weld nut are provided on the first platen 5 and the second platen, respectively. The upper cover body 1 is provided with a first connecting hole, and the lower cover body 2 is provided with a second connecting hole.

Namely, when the access panel 8 is pivoted to the second position for closing the observation port, the first lock catch 81 realizes connection between the access panel 8 and the upper cover body 1, so that the protection and noise reduction performance of the coupler protection cover are prevented from being influenced due to the fact that the access panel 8 is opened by mistake. Meanwhile, when maintenance is needed, the first lock catch 81 is only required to be unlocked, the maintenance plate 8 is rotated through the first handle 82, and the maintenance plate 8 is easy and convenient to open.

In some embodiments, as shown in fig. 1-4, the upper housing 1 includes first and second baffles 11, 12 that are axially opposite along the first mating bore.
