This utility model has a reasonable structural design, adding a slider to the bottom of the device, which is limited by a spring and a limiting block to achieve multi-level adjustment. The length can be adjusted according to the user's needs, making it convenient to use. At the same time, the buffer pad can protect the patient's head and avoid discomfort caused by prolonged wear, greatly improving practicality. Two sets of sound-absorbing sponges are added at the ear position to fill the space of the mounting base, maximizing the sound insulation effect. Meanwhile, the foam plug can be threadedly connected through the lead screw and threaded hole, making it easy to disassemble and install, and convenient to disinfect. It is convenient and quick to use, greatly improving practicality."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: When the device is in use, although it can be limited by springs and limit blocks to achieve multi-level adjustment, it is necessary to press two limit blocks at the same time during adjustment, so only the distance of one soundproof cover can be adjusted at a time.

[0005] Therefore, this application provides a noise reduction and protection device that facilitates the removal of foam plugs, in order to solve the problems mentioned in the background art. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a noise reduction and protection device for easy disassembly of foam plugs, comprising two soundproof covers, two fixed shells, a first fixed block and a slider. A second fixed block is fixedly installed at the upper inner end of the first fixed block. Two second fixed posts are slidably installed on both sides of the inner interior of the second fixed block. A spring is connected between the side of the two second fixed posts that are close to each other and the second fixed block. A connecting rope is fixedly installed on the side of the two second fixed posts that are close to each other. The ends of the two connecting ropes that are close to each other pass through the second fixed block and are fixedly installed at the upper end of the slider.

[0008] Both of the two fixed shells have multiple fixing holes on both sides, and the two soundproof covers include a connecting block, an outer shell, and a second fixing frame.

[0009] Furthermore, a connecting rod is connected between the two fixed shells, and a sponge pad is fixedly installed at the lower inner end of the connecting rod.

[0010] Furthermore, the first fixing block, two springs, two connecting ropes, two second fixing columns, the second fixing block, and the slider are all provided in two sets, and the two connecting blocks are respectively rotatably set at the lower ends of the two first fixing blocks.

[0011] Furthermore, the two fixing blocks are slidably disposed inside the two fixing shells, and a pull rod is fixedly disposed on the side of each of the two sliders that are far apart from each other.

[0017] 1. This utility model proposes a noise reduction and protection device that facilitates the removal of foam plugs. When using the device, it is worn on the head and pulled to move the slider downwards. The slider moves the first fixing post through the connecting rope, causing it to disengage from the fixing hole, thereby adjusting the length. This allows the user to adjust the length of two soundproof covers at the same time, improving efficiency. After adjustment, the second fixing post is pushed to pop out again, which helps to fix the first fixing block and thus fix the adjusted length.

[0018] 2. The present invention proposes a noise reduction and protection device that facilitates the removal of foam plugs. When using the device, the soundproof cover can be rotated to adjust its angle. After the soundproof cover has been used for a period of time, the soundproof foam cover and the second fixing bracket can be cleaned. After cleaning, the second fixing bracket is placed inside the outer shell, and then the second fixing bracket is pressed firmly so that the rubber ring is engaged inside the fixing groove, thus completing the installation. It is easy to install and remove. Attached Figure Description
