Description

Technical Field

[0001] This utility model relates to the field of machine cover technology, specifically to a noise-reducing machine cover. Background Technology

[0002] Noise-reducing machine enclosures, also commonly known as soundproof enclosures or noise-reducing soundproof covers, are professional soundproofing devices designed to reduce noise pollution generated by machines or equipment. They are made of high-density sound-absorbing and sound-insulating materials, and their structure typically includes a steel frame, sound insulation panels (or non-metallic sound insulation panels), and sound-absorbing materials such as perforated rock wool panels. These materials effectively isolate external noise, confining it within the enclosure and thus reducing the ambient noise level, achieving a noise reduction effect.

[0003] Traditional machine covers are installed on the machine to isolate the noise generated when the machine is running. However, in actual use, the machine cover is fixed with multiple bolts. When the machine needs to be cleaned or repaired, auxiliary tools are needed to loosen the bolts and then disconnect the machine cover, which greatly increases the workload.

[0004] Therefore, it is particularly important to improve existing noise-reducing hoods and design a new type of noise-reducing hood to address the aforementioned technical deficiencies and enhance the overall practicality of noise-reducing hoods. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example: Please refer to Figures 1-6 This utility model provides a technical solution:

[0029] A noise-reducing machine cover includes a protective cover 1, which is composed of a first frame 2 and a second frame 3. A first sound-insulating cotton 4 and a second sound-insulating cotton 5 are fixedly connected to the inner walls of both the first frame 2 and the second frame 3. The first sound-insulating cotton 4 and the second sound-insulating cotton 5 are designed in a cross-shaped structure. A first spring 6 is fixedly connected to the top of the inner side of the first frame 2, and a fixing plate 7 is fixedly connected inside the first spring 6. A first button 8 and a second button 9 are slidably connected to the top of the second frame 3. A through groove is provided at the top of the inner side of the second frame 3 corresponding to the position of the fixing plate 7. The first button 8 and the second button 9 extend into the through groove. The first frame 2 and the second frame 3 are fitted onto the outside of the machine. Then, the first frame 2 and the second frame 3 are brought together so that the fixing plate 7 is inserted into the through groove, completing the assembly of the protective cover 1. The first sound-insulating cotton 4 and the second sound-insulating cotton 5 then block the noise generated by the machine inside the protective cover 1. Its unique material structure and density design can effectively absorb and reflect sound energy, thereby reducing the sound propagation efficiency.

[0030] Furthermore, in this embodiment, a receiving groove 10 is provided in the middle of the interior of the fixing plate 7. One side of the receiving groove 10 is designed with a sloping structure. A placement groove 11 is provided inside the fixing plate 7 on the side away from the first spring 6. The top of the inner side of the placement groove 11 is designed with a sloping structure. An extension block 12 is fixedly connected to the left end of the inner side of the placement groove 11. The placement groove 11 is designed with an L-shaped structure. After the fixing plate 7 is inserted into the interior of the through groove, the extension and retraction of the first spring 6 always supports the fixing plate 7, so that it always faces the interior of the through groove, thus completing the connection between the first frame 2 and the second frame 3.

[0031] Furthermore, in this embodiment, a rod 13 is fixedly connected to the bottom of the first button 8, a second spring 14 is sleeved on the outside of the rod 13, and a stop bar 15 is fixedly connected to the bottom end of the rod 13. A fixing rod 16 is fixedly connected to the bottom of the second button 9, a third spring 17 is sleeved on the outside of the fixing rod 16, and a connecting rod 18 is fixedly connected to the bottom end of the fixing rod 16. The connecting rod 18 has a beveled structure design. After the fixing plate 7 is inserted into the through groove, the fixing rod 16 will then enter the placement groove 11, and at the same time, the connecting rod 18 will be inserted into the bottom of the extension block 12. When the first frame 2 and the second frame 3 need to be separated, the first button 8 is pressed, the insert rod 13 enters the interior of the receiving groove 10, and the stop rod 15 presses against the inclined side wall of the receiving groove 10, so that the fixed plate 7 presses against the first spring 6 and slides to the left, thereby making the bottom of the extension block 12 disengage from the connecting rod 18. At the same time, the extension and retraction of the third spring 17 stores energy, so that the second button 9 is reset, and the connection between the two is released, making it convenient to separate the first frame 2 and the second frame 3.

[0032] Furthermore, in this embodiment, a pad 19 is fixedly connected to the bottom of the inner side of the first frame 2, a fixing frame 20 is symmetrically fixedly connected to the outside of the pad 19, an arc frame 21 is rotatably connected inside the fixing frame 20, a connecting ear 22 is symmetrically fixedly connected to the outside of the arc frame 21, a fourth spring 23 is fixedly connected between the connecting ear 22 and the pad 19, a slot is provided in the middle of the inside of the pad 19, and a spherical block 24 is fixedly connected to the bottom of the inner side of the second frame 3 at a position corresponding to the arc frame 21. After the top ends of the first frame 2 and the second frame 3 are connected, the spherical block 24 will directly squeeze the arc frame 21, and then the arc frame 21 will unfold to both sides. When the spherical block 24 completely enters the interior of the arc frame 21, the arc frame 21 will close the opening under the action of the fourth spring 23, thereby merging the spherical block 24 and the arc frame 21.

[0033] Furthermore, in this embodiment, the arc frame 21 is composed of a first arc plate and a second arc plate. The first arc plate has a through groove inside, and a connecting block is fixedly connected to the second arc plate at a position corresponding to the through groove. The second arc plate is rotatably connected to the first arc plate through the connecting block. When the spherical block 24 presses against the arc frame 21, the second arc plate rotates under the action of the connecting block, so that the first arc plate and the second arc plate unfold each other, making it convenient for the spherical block 24 to enter the interior of the arc frame 21.

[0034] Furthermore, in this embodiment, a square groove is provided on the outer side of the second frame 3, and a straight groove is provided inside the square groove. Multiple sets of glass 25 are slidably connected inside the straight groove, and a fixing pad is rotatably connected at the connection of the multiple sets of glass 25. Through the design of the glass 25, the movement state of the machine inside the protective cover 1 can be directly observed. When the machine is not in use, the glass 25 needs to be moved to make the glass 25 slide inside the straight groove. Subsequently, the design of the fixing pad makes the glass 25 folded, allowing the outside air to circulate with the inside of the protective cover 1 to cool the machine.

[0035] In this embodiment, the specific implementation scenario is as follows: the first frame 2 and the second frame 3 are fitted onto the outside of the machine, and then the first frame 2 and the second frame 3 are brought together so that the fixing plate 7 is inserted into the through slot. Then the fixing rod 16 enters the placement slot 11, and the connecting rod 18 is inserted into the bottom of the extension block 12 to limit the fixing plate 7. When it is necessary to separate the first frame 2 and the second frame 3, the first button 8 is pressed, and the insert rod 13 enters the receiving slot 10. The stop rod 15 presses against the inclined side wall of the receiving slot 10, so that the fixing plate 7 presses against the first spring 6 and slides to the left. Then the bottom of the extension block 12 is disengaged from the connecting rod 18, and the connection between the two is released, making it easy to separate the first frame 2 and the second frame 3. At the same time, the extension and retraction of the third spring 17 stores energy to reset the second button 9. After the tops of the first frame 2 and the second frame 3 are connected, the spherical block 24... The first and second arc plates are directly squeezed by the connecting block, allowing the spherical block 24 to fit into the arc frame 21. The arc frame 21 is then closed by the fourth spring 23, allowing the spherical block 24 to merge with the arc frame 21, thus completing the assembly of the protective cover 1. The first and second sound insulation cotton 4 and the second sound insulation cotton 5 are then used to block the noise generated by the machine inside the protective cover 1. Their unique material structure and density design can effectively absorb and reflect sound energy, thereby reducing the sound propagation efficiency. The design of the glass 25 allows direct observation of the machine's movement inside the protective cover 1. When the machine is not in use, the glass 25 can be moved to slide inside the straight groove. The design of the fixing pad allows the glass 25 to fold, allowing outside air to circulate with the inside of the protective cover 1 and cooling the machine.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
