[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1 and Figure 2 , an embodiment provided by the utility model: a soundproof box, including a base 1, the outer side of the base 1 is provided with open grooves 3, the inside of the open groove 3 is rotatably connected with a rotating rod 4, the top of the rotating rod 4 is fixedly connected with a baffle 5, and the outer walls of the plurality of rotating rods 4 are provided with torsion springs 6 on both sides, one end of the plurality of torsion springs 6 is respectively fixedly connected to one side of the corresponding baffle 5, and the other end of the plurality of torsion springs 6 is respectively fixedly connected to one side of the corresponding inner side of the open groove 3, a box cover 7 is provided on the upper side of the base 1, and the inner top of the box cover 7 is slidably connected with a clamping plate 8 around the inner side, and the outer side of the box cover 7 is threadedly connected with a plurality of bolts 9 around, one end of the plurality of bolts 9 passes through the box cover 7 and is rotatably connected to one side of the corresponding clamping plate 8, and an adjusting mechanism 2 is provided inside the baffle 5;

[0039] Specifically, first place the mechanical equipment that needs to be soundproofed on the base 1. The design of the base 1 is stable and sturdy, which can ensure that the equipment will not shake during the sound insulation process. Next, we rotate the baffles 5 on all sides upward through the rotating rod 4 to make them perpendicular to the base 1. This design makes the space of the soundproof box independent and the noise propagation is limited. After completing the above steps, we put the box cover 7 on the four baffles 5, and then tighten the bolts 9. The purpose of this step is to drive the surrounding plywood 8 to move toward the middle to limit and fix the baffles 5. This can prevent the baffles 5 from rebounding during the sound insulation process, thereby affecting the sound insulation effect. When using the soundproof box, after the operation is completed, the above steps can be reversed for storage. This design greatly reduces the space occupied by the soundproof box when not in use. There is no need to remove the surrounding edges and base 1 for classified storage, thereby reducing the time for the next installation and the burden on the staff.

[0040] Reference Figure 1 , Figure 3 and Figure 4 The adjusting mechanism 2 includes a groove 201, and a plurality of grooves 201 are respectively provided on the inner side of the corresponding baffle 5. A movable plate 202 is slidably connected inside the groove 201. A hole 203 is provided on one side of the movable plate 202. A tension spring 204 is fixedly connected to one side of the hole 203. One end of the tension spring 204 is fixedly connected to a limiting rod 205. A plurality of limiting holes 206 are equidistantly provided on one side of the baffle 5. The sizes of the plurality of movable plates 202 are respectively matched with the sizes of the corresponding inner sides of the groove 201. The plurality of limiting rods 205 are respectively plugged into the corresponding limiting holes 206.

[0041] Specifically, before placing the mechanical equipment, we need to carefully observe its volume first. This is because larger equipment may require a more complicated installation process or have higher space requirements for the device. Next, a key step we have to take is to operate the limit rod 205, which plays a vital role in the device. When we press it, the tension spring 204 will be squeezed, thereby driving the limit rod 205 to disengage from the limit hole 206. This process is to allow the device to enter the next stage, that is, to adjust the height of the box. When the limit rod 205 enters the hole 203, we can pull the movable plate 202 upward. This operation will increase the overall height of the box, so that the device can adapt to mechanical equipment of different volumes. This flexibility is an important manifestation of the practicality of the device. After adjusting the height, the limit rod 205 will pop out of the corresponding limit hole 206 due to the elastic force of the spring, and limit the movable plate 202, so that it can easily adapt to mechanical equipment of various volumes, improving the practicality of the device.

[0042] Reference Figure 2A hollow plate 10 is fixedly connected to one side of the plurality of baffles 5 and the middle of the inner top of the box cover 7, and a sound insulation cotton 11 is arranged inside the hollow plate 10. The sizes of the plurality of hollow plates 10 are respectively matched with the sizes of the corresponding baffles 5 and the box cover 7;

[0043] Specifically, the noise generated by mechanical equipment can be isolated by the sound insulation cotton 11, so that the external environment can be protected from the influence of the noise.

[0044] Reference Figure 1 and Figure 2 The bottom of the base 1 is provided with anti-slip grooves 12, and the front middle and lower part of the front baffle 5 is provided with an observation window 13;

[0045] Specifically, the anti-slip grooves 12 can increase the stability of the device, and the observation window 13 can facilitate the staff to observe the internal conditions of the area surrounded by the baffle 5 at any time, so that they can respond in time when encountering special situations.

[0046] Working principle: When using the soundproof box, first carry it to the location where it is to be used, then place the mechanical equipment that needs soundproofing on the base 1, and then rotate the baffles 5 on all sides upwards through the rotating rod 4 to make them perpendicular to the base 1. At this time, put the box cover 7 on the four baffles 5, and then tighten the bolts 9 to drive the splints 8 on all sides to move toward the middle to limit and fix the baffles 5 to prevent them from rebounding and affecting the normal sound insulation work. At this time, the hollow plate 10 and sound insulation cotton 11 can be set to isolate the noise generated by the mechanical equipment, and the external environment can be protected from the influence of noise. After the use of the soundproof box, reverse the above process to store the soundproof box. When the soundproof box is not in use, its occupied space can be reduced. There is no need to remove the surround and the base 1 for classified storage, which can reduce the next installation time of the sound insulation box, and further reduce the workload of the staff, and can meet the needs of users. Before placing the mechanical equipment, first observe its size, and then press the limit rod 205. At this time, the tension spring 204 is squeezed to drive the limit rod 205 to disengage from the limit hole 206 and enter the hole 203. At this time, pulling the movable plate 202 upward can increase the overall height of the box. After the height is adjusted, the limit rod 205 will pop out from the corresponding limit hole 206 through the elastic force of the tension spring 204 to limit the movable plate 202, so that it can be suitable for mechanical equipment of different sizes, and thus the practicality of the device can be improved.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
