Technical Field

[0001] This utility model relates to the field of soundproofing equipment technology, and in particular to a soundproofing ear cover with a buffer bracket. Background Technology

[0002] In modern life, noise pollution has become a significant factor affecting people's quality of life and health. Whether it's the roar of machines in factory workshops, the noisy work at construction sites, the constant traffic on main roads, or the commotion caused by dense crowds in public places, all of these factors interfere with people's lives and work to varying degrees. Long-term exposure to high-decibel noise can not only lead to hearing loss, tinnitus, and other ear problems, but may also cause a series of health risks such as insomnia, anxiety, and difficulty concentrating.

[0003] Traditional noise-canceling earmuffs have also revealed some problems in actual use. Some earmuffs are only worn through a simple fixed structure, which is not good in terms of adjustment and fit. They are difficult to meet the diverse wearing needs of different users and cannot flexibly adapt to various head shapes and ear contours, making it difficult to balance the stability and comfort of wearing them. Utility Model Content

[0004] The purpose of this invention is to provide a soundproof earmuff with a buffer bracket. By turning the adjusting nut, the position of the abutment plate on the threaded post can be changed, thereby achieving fine adjustment of the tightness of the earmuff to meet the wearing needs of different users. The positioning block on the outer surface of the damping slider can limit the excessive offset of the connecting plate and the abutment plate, ensuring a reasonable adjustment range and avoiding unstable earmuff wearing or decreased comfort due to excessive adjustment.

[0005] To achieve the above objectives, a sound-absorbing earmuff with a buffer support is provided, comprising: a headband support; fixing blocks are fixedly connected to both sides of the lower surface of the headband support; a triangular support is fixedly connected to the fixing blocks through the cooperation of limiting blocks and fixing bolts; two damping sliders are slidably connected to the outer surface of the triangular support; two positioning blocks are fixedly connected to the upper and lower sides of the outer surfaces of the two damping sliders; two adjustment grooves are formed inside the two damping sliders; two guide posts are fixedly connected to the inner surfaces of the two adjustment grooves; a return spring is sleeved on the outer surface of the two guide posts; a contact plate abuts against the side wall of the return spring; a connecting plate is fixedly connected to the contact plate through threaded posts and adjusting nuts; and an earmuff is fixedly connected to the side of the connecting plate away from the threaded posts. This enhances the stability of the connection between components, prevents loosening and displacement, ensures the stability of the overall structure, and lays the foundation for collaborative operation.

[0006] According to the aforementioned sound-absorbing ear cover with a buffer bracket, the number of damping sliders corresponds to the number of triangular brackets. Two adjustment slots are symmetrically arranged on the front and rear sides inside the damping sliders, and the interior of each adjustment slot is connected to the upper and lower sides of the outer surface of the damping slider. This ensures component matching and symmetry, facilitates installation and assembly, and improves structural rationality and operational stability.

[0007] According to the aforementioned soundproof ear cover with a buffer bracket, the outer surfaces of the contact plate and the guide post are slidably connected, and the number of the return springs corresponds to the number of the guide posts. This ensures smooth sliding of the contact plate, uniform force on the springs, and improves the fitting accuracy of the components and overall stability.

[0008] According to the aforementioned sound-insulating ear cover with a buffer bracket, the adjusting nut abuts against the side wall of the contact plate, and the threaded post and connecting plate are fixedly connected. This facilitates fixing the position of the contact plate, ensures a firm connection, and improves structural reliability and ease of adjustment.

[0009] According to the aforementioned soundproof ear cover with a buffer bracket, both the positioning block and the abutment plate are slidably connected to the outer surface of the threaded post, and the positioning block is located between the connecting plate and the abutment plate. This facilitates the sliding adjustment of the components, and the positioning block plays a role in interval positioning, ensuring orderly adjustment.

[0010] According to the aforementioned sound-absorbing earmuff with a buffer support, the earmuff is located between two damping sliders, and the size of the earmuff matches the size of the damping sliders. This ensures stable installation of the earmuff, and the size fit improves the fit, enhancing the sound insulation effect and wearing comfort.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] This utility model includes a fixing block, a limiting block, a fixing bolt, a triangular bracket, a damping slider, a positioning block, an adjusting groove, a guide post, a return spring, a contact plate, a threaded post, an adjusting nut, a connecting plate, and earcups. By turning the adjusting nut, the position of the contact plate on the threaded post can be changed, allowing for fine-tuning of the earcup tightness to meet the wearing needs of different users. The positioning block on the outer surface of the damping slider can limit excessive offset of the connecting plate and the contact plate, ensuring a reasonable adjustment range and preventing earcups from becoming unstable or losing comfort due to over-adjustment.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5This utility model discloses a soundproof earmuff with a buffer bracket, comprising: a headband bracket 1, with fixing blocks 10 fixedly connected to both the left and right sides of the lower surface of the headband bracket 1. The fixing blocks 10 provide a stable connection base for the installation of a triangular bracket 11, allowing the triangular bracket 11 to be reliably fixed to the headband bracket 1. The fixing blocks 10 are fixedly connected to the triangular bracket 11 through the cooperation of limiting blocks 12 and fixing bolts 13. The limiting blocks 12 limit the triangular bracket 11 to prevent it from shifting on the fixing blocks 10, and the fixing bolts 13 further firmly fix the triangular bracket 11 to the fixing blocks 10. The above ensures the stability of the tripod bracket 11 installation. Two damping sliders 3 are slidably connected to the outer surface of the tripod bracket 11. These sliders 3 can slide along the tripod bracket 11, facilitating adjustment of the earcup 2 position according to actual needs. Simultaneously, the damping properties provide cushioning during the sliding process, preventing excessive sliding. Two positioning blocks 7 are fixedly connected to the upper and lower sides of the outer surface of the two damping sliders 3. The positioning blocks 7 limit the position of the connecting plate 5 and the contact plate 8 on the threaded post 6, preventing excessive displacement during sliding. Two adjustment grooves 4 are provided inside each of the two damping sliders 3. 4 provides installation space for components such as guide posts, return springs 14, and contact plates 8, facilitating their coordinated operation. Two guide posts are fixedly connected to the inner surfaces of both adjustment slots 4. These guide posts guide the extension and retraction of the return springs 14 and the sliding of the contact plates 8, ensuring they can only move along the axial direction of the guide posts. Return springs 14 are sleeved on the outer surfaces of the two guide posts. The springs 14, fitted onto the guide posts, provide elasticity that ensures the contact plates 8 are always under pressure, guaranteeing a tight fit between the contact plates 8 and other components. The sidewalls of the return springs 14 abut against the contact plates 8. Under the tightening action of 4, the force is transmitted to the connecting plate 5 through the threaded post 6, thereby keeping the earmuff 2 in a stable position. The abutment plate 8 is fixedly connected to the connecting plate 5 through the threaded post 6 and the adjusting nut 9. The threaded post 6 connects the abutment plate 8 and the connecting plate 5 together. The adjusting nut 9 can adjust the distance between the abutment plate 8 and the connecting plate 5 by cooperating with the threaded post 6, thereby adjusting the position of the earmuff 2. The earmuff 2 is fixedly connected to the side of the connecting plate 5 away from the threaded post 6. The connecting plate 5 serves to connect the abutment plate 8 and the earmuff 2, and transmits the force of each component to the earmuff 2, ensuring that the earmuff 2 can be stably worn in the ear.

[0024] The number of damping sliders 3 corresponds to the number of triangular brackets 11. This arrangement ensures that each triangular bracket 11 is equipped with a corresponding damping slider 3, guaranteeing that the installation and adjustment structures of the earcups 2 on both sides are symmetrical and consistent. Two adjustment slots 4 are symmetrically arranged on the front and rear sides inside the damping slider 3. The symmetrical arrangement of the adjustment slots 4 ensures that the components inside the damping slider 3 are subjected to uniform force, ensuring the stability of the earcups 2 during adjustment. The interior of the adjustment slots 4 is connected to the upper and lower sides of the outer surface of the damping slider 3. This connection structure facilitates the passage of components such as threaded posts 6 through the damping slider 3, realizing the connection between the contact plate 8 and the connecting plate 5. The contact plate 8 and the outer surface of the guide post are slidably connected, allowing the contact plate 8 to slide smoothly along the guide post. Under the action of the return spring 14, the position can be flexibly adjusted to ensure the stability of the force on the earcups 2. The number of return springs 14 corresponds to the number of guide posts. Each guide post is equipped with a return spring 14, which can apply a tightening force to the contact plate 8 from multiple directions, making the force on the contact plate 8 even. The adjusting nut 9 and the contact plate 8 The side wall of the earcup 2 is in contact with the adjusting nut 9, which in turn contacts the contact plate 8. This fixes the position of the contact plate 8 on the threaded post 6, preventing it from loosening during use. The threaded post 6 and the connecting plate 5 are fixedly connected, ensuring that the threaded post 6 can stably drive the connecting plate 5 and the earcup 2 to adjust their positions, thus ensuring the connection is firm. The positioning block 7 and the contact plate 8 are both slidably connected to the outer surface of the threaded post 6, allowing the positioning block 7 and the contact plate 8 to slide along the threaded post 6, making it easy to adjust their relative positions as needed. The positioning block 7 is located between the connecting plate 5 and the contact plate 8, and it serves to space and position the two plates, preventing them from directly contacting each other and affecting the adjustment effect. The earcup 2 is located between the two damping sliders 3. This position setting allows the earcup 2 to be stably supported by the two damping sliders 3, ensuring stability and comfort when wearing it. The size of the earcup 2 and the size of the damping sliders 3 are matched, which makes the fit between the earcup 2 and the damping sliders 3 tighter, reducing shaking during use and improving the sound insulation effect.

[0025] Working principle: When using the noise-isolating earmuffs with buffer brackets, first place the headband bracket 1 on the head in a suitable position. Then, push the damping slider 3 to slide along the triangular bracket 11. Adjust the front and back position of the earmuff 2 by sliding the damping slider 3. The damping characteristics make the sliding process smoother and avoid too abrupt adjustments. After the position is roughly determined, if you need to fine-tune the tightness of the earmuff 2, you can turn the adjusting nut 9. Since the adjusting nut 9 abuts against the side wall of the abutment plate 8, turning it will change the position of the abutment plate 8 on the threaded post 6, thereby moving the earmuff 2 through the connecting plate 5. During this process, the positioning block 7 limits the excessive offset of the connecting plate 5 and the abutment plate 8, ensuring a reasonable adjustment range. At the same time, the abutment plate 8 slides along the guide post, which ensures that its sliding direction is stable. The return spring 14 is sleeved on the guide post and exerts a pressing force on the abutment plate 8, so that the abutment plate 8, the threaded post 6, and the connecting plate 5 maintain a tight fit, thereby allowing the earcups 2 to fit stably against the ears. After the adjustment is completed, the earcups 2 are located between the two damping sliders 3, and because of the size fit, they can fit tightly with the damping sliders 3, reducing shaking during use and ensuring sound insulation and wearing stability.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
