[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1-4, the present utility model provides a technical solution: a foldable noise reduction protection device, including: a top plate 1, two groups of first side plates 2 and second side plates 3 are respectively arranged on both sides of the top plate 1, hinges 4 are arranged at the joints of the top plate 1 with the first side plates 2 and the second side plates 3, fixing bolts 5 are arranged inside the hinges 4, and the top plate 1, the first side plates 2 and the second side plates 3 are fixedly connected to the hinges 4 through the fixing bolts 5. A motor notch 6 is arranged inside one group of the second side plates 3. The top plate 1, the first side plates 2 and the second side plates 3 rotate with each other through the hinges 4 to form a rectangular protection structure. The protective cover is made of transparent organic glass material, has a rectangular structure, is provided with a motor installation notch on one side, and adopts a double-layer design, which is more stable and safe during operation, can also effectively reduce the noise of the high-speed rotation of the speed test bench, and prevent the test parts from flying out. The organic glass has good transparency, chemical stability, mechanical properties and weather resistance, is easy to dye, easy to process, and has beautiful appearance, etc., thereby improving the transparency of the speed protection cover, and can also effectively prevent the occurrence of fragmentation, greatly improving the durability. When in use, the protection cover can be installed on the top of the speed test bench to carry out rotation test work, further improving the working environment of the staff. By adopting the folding method of the hinges 4, the four-side protection plates of the protection cover are folded and retracted through the hinges 4, so that the protection cover is more flexible and convenient to retract, easier to move, and reduces a certain burden on the test bench operator.
[0017] Further improved, as Figure 2 , 3 shown: A connecting column 9 is arranged on the side surface of the second side plate 3 and a through hole 7 is arranged inside the first side plate 2. The connecting column 9 and the through hole 7 correspond to each other, and this setting ensures the stability of the installation of the first side plate 2.
