DETAILED DESCRIPTION
[0018] like Figure 4 As shown, a noise reduction device for hardware production includes a sound insulation box 10, which is composed of an inner layer 11 and an outer layer 12. The outer layer 12 is made of metal, and the inner layer 11 is made of sound-absorbing sponge material. The sound insulation box 10 has excellent noise reduction effect and is impact-resistant on the outside through the composition of the inner and outer layers.
[0019] refer to Figure 1 , 2 The interior of the soundproof box 10 is hollow and the front is open. Support blocks 20 are fixedly connected to the left and right sides of the top front end of the soundproof box 10. A rotating rod 21 is rotatably connected to the opposite side of the support block 20. A cover plate 30 is fixedly connected to the rotating rod 21. The flip-top design facilitates the opening and closing of the soundproof box 10.
[0020] The right side of the rotating rod 21 is fixedly connected to the gear 40; the top right side of the sound insulation box 10 is fixedly connected to a fixing plate 41, the front side of the fixing plate 41 is fixedly connected to a cylinder 42, the output end of the cylinder 42 is fixedly connected to a toothed plate 43, and the toothed plate 43 is meshed with the gear 40.
[0021] When in use, the cylinder 42 is activated by an external power supply, and the output end of the cylinder 42 extends, and through the cooperation of the gear 40 and the toothed plate 43, the rotating rod 21 is driven to rotate, and the cover plate 30 is driven to flip downward until the cover plate 30 covers the front of the soundproof box 10, and the protruding strip 33 is embedded in the groove 32, so that the soundproof box 10 is closed and the soundproof effect is achieved. When the output end of the cylinder 42 is retracted, it can drive the cover plate 30 to flip upward, so that the front of the soundproof box 10 is exposed.
[0022] Preferably, reference Figure 1 , 2 The front of the soundproof box 10 is fixedly connected with a closing strip 31, and a groove 32 is formed on the front of the closing strip 31; the bottom of the cover plate 30 is fixedly connected with a protruding strip 33. The protruding strip 33 is adapted to the shape of the groove 32.
[0023] Preferably, the groove 32 is in the shape of a "mouth", and after the grooves 32 connected on four sides are embedded with the protruding strips 33, the cover plate 30 can completely fit the surface of the closing strip 31, thereby reducing the gap at the connection between the cover plate 30 and the closing strip 31.
[0024] Preferably, the sealing strip 31 and the protruding strip 33 are made of rubber material, which has a strong sound insulation effect and can prevent sound from leaking out from the sealing strip 31 .
[0025] When the sound insulation box 10 is in use, a window needs to be opened on its rear side wall, and the functional mechanisms of the hardware processing equipment are extended from the rear side of the sound insulation box 10, such as the cutting mechanism of the cutting machine, the drilling mechanism of the drilling machine, etc., to realize the use of the hardware processing equipment in the sound insulation box 10.
[0026] Among them, the front side of the sound insulation box, that is, the side where the cover is located, is the operating side where the operator operates, and the window is located on the back side of the sound insulation box, away from the operating side. Even if noise leaks directly from the window during processing, the impact on the operator is relatively small.
[0027] Since the hardware products cannot be fixed when placed in the soundproof box 10, they may slide and affect the production efficiency. Therefore, a fixing device for the hardware products is designed, wherein the fixing device is used to match the functional mechanism of the processing equipment extending into the soundproof box 10, so that the functional mechanism can directly process the hardware products fixed on the fixing device.
[0028] refer to Figure 1 , 3 4. Slide rails 50 are fixedly connected to the left and right sides of the interior of the soundproof box 10, and the sliding ends of the slide rails 50 on both sides are fixedly connected to support plates 51. The slide rails 50 can facilitate the support plates 51 to slide out of the interior of the soundproof box 10, so that hardware products can be placed on the support plates 51.
[0029] refer to Figure 1 , 3 4. Positioning plates 52 are fixedly connected to the left and right sides of the top of the support plate 51, and support columns 53 are threadedly connected to the middle positions of the left and right sides of the positioning plate 52. Bearings 54 are installed on the opposite sides of the support columns 53. The inner ring of the bearing 54 is fixedly connected to the support column 53, and the outer ring of the bearing 54 is fixedly connected to the clamping plate 55.
[0030] Preferably, reference Figure 1 , 3 4. Hollow columns 56 are fixedly connected at the front and rear ends of the opposite sides of the two positioning plates 52, and slide bars 57 are slidably connected to the opposite sides of the two groups of hollow columns 56. The side of the slide bar 57 away from the hollow column 56 is fixedly connected to the clamping plate 55. When the clamping plate 55 moves, it will drive the slide bar 57 to slide along the inside of the hollow column 56, so as to achieve the effect of guiding the clamping plate 55 when moving.
[0031] When in use, the hardware product is placed on the support plate 51, and the support columns 53 on both sides are rotated, so that the support columns 53 rotate and move toward each other, thereby driving the clamping plates 55 on both sides to move toward each other to clamp and fix the hardware product.
[0032] The working principle of the utility model is: the cylinder 42 is started by an external power supply, the output end of the cylinder 42 extends, and through the cooperation of the gear 40 and the tooth plate 43, the rotating rod 21 is driven to rotate, and the cover plate 30 is driven to flip downward until the cover plate 30 covers the front of the soundproof box 10, and the protruding strip 33 is embedded in the groove 32, so that the soundproof box 10 is closed and the soundproof effect is achieved. When the output end of the cylinder 42 is contracted, it can drive the cover plate 30 to flip upward, so that the front of the soundproof box 10 is exposed.
[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
