Description

Technical Field

[0001] This utility model belongs to the field of noise-proof safety helmet technology, and more specifically, relates to a noise-protective safety helmet. Background Technology

[0002] Construction noise poses a threat to the hearing health of workers. Prolonged exposure to high-noise environments can lead to hearing loss, tinnitus, and other auditory system damage, even developing into occupational noise-induced deafness. Therefore, noise protection is receiving increasing attention. Noise-canceling earmuffs are an effective means of noise protection, but their use significantly impacts the wearing of safety helmets, affecting compliance with earmuff usage guidelines. Existing technologies, including CN 219813313 U "A Safety Helmet with Accompanying Earmuffs" and CN214340415 U "A Safety Helmet with Accompanying Earmuffs," propose integrated designs for noise-canceling earmuffs and safety helmets, which to some extent solves the discomfort problem of "overlapping" protective gear. However, research on the application of construction protective earmuffs reveals two key issues that existing patents have not adequately addressed: firstly, the connection between the earmuff and the safety helmet is not stable or secure enough, and the position adjustment is not flexible enough; secondly, prolonged wear of the earmuffs causes discomfort due to pressure and lack of breathability. A new design is urgently needed to provide an effective solution to these problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a noise-protective helmet that solves the problem of discomfort when wearing noise-canceling headphones for extended periods.

[0026] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] like Figure 1-2 As shown, a noise-protective safety helmet includes:

[0028] The cap body has an array of holes on both sides;

[0029] Two connecting seats 3 are detachably connected to the array holes, and the position of the connecting seats 3 can be adjusted within the entire row of holes 2;

[0030] The elastic bow frame 4 has one end connected to the connecting seat 3 and the other end of the elastic bow frame 4 is equipped with noise-canceling earmuffs 5.

[0031] Earplug case 6, which is set on cap body 1, is used to store in-ear earplugs.

[0032] Specifically, the cap body 1 and earplugs are connected by the connecting seat 3 in conjunction with the array holes 2. The installation position can be adjusted by changing the position of the connecting seat 3 within the area of ​​the array holes 2, thus adapting to users of different body types. The elastic arch frame 4 ensures that the noise-canceling earmuffs 5 fit snugly against the ears. The earplug case 6 stores the in-ear earplugs. The in-ear earplugs and noise-canceling earmuffs 5 can be used alternately to significantly alleviate the discomfort caused by pressure and lack of breathability when wearing earmuffs for extended periods. At the same time, the two can also be used together to improve the noise cancellation level.

[0033] In this embodiment, the array aperture includes a platform with 8×8 screw holes. The connecting seat 3 includes a base with 2×2 bolts 7 rotatably connected to the base. One end of the bolts 7 is threadedly connected to the screw holes, and the other end of the bolts 7 is provided with a manual drive unit.

[0034] Specifically, the cap body 1 and the connecting seat 3 are fixed by bolt 7 and screw hole. Bolt 7 is turned by manual drive, without the need for tools, which is convenient to use.

[0035] Furthermore, the manually driven part is a sheet or column, which facilitates the rotation of bolt 7 without tools.

[0036] Furthermore, if the spacing of the array holes 2 is too small, a planetary gear structure can be formed by setting teeth on the outer periphery of each bolt 7, setting gears at the center of each bolt 7, or setting toothed rings on the outer periphery to drive the screwing in a unified manner.

[0037] In this embodiment, a turntable is rotatably connected to the base, and the elastic bow frame 4 is connected to the turntable, so that the elastic bow frame 4 can be folded and stored close to the back of the head area for noise-canceling earmuffs 5.

[0038] Specifically, the position of the elastic bow frame 4 is adjusted by the dial, so that the cap body 1 can be worn and the in-ear earphones can be switched without disassembling the connecting seat 3.

[0039] Furthermore, the turntable is ring-shaped and rotatably connected to the outer periphery of the base. The outer periphery is connected to the elastic bow frame 4, which facilitates the rotation and folding of the elastic bow frame 4 while avoiding obstruction of the screw 7 from being tightened.

[0040] In this embodiment, the platform protrudes outward from the cap body 1, and the screw hole is a blind hole structure.

[0041] Specifically, the blind hole structure avoids reducing the protective and sound insulation effect due to the openness of the screw holes.

[0042] In this embodiment, the cap body 1 is provided with a triangular hanging strap 8, which avoids the ear area.

[0043] Specifically, the triangular strap ensures that the hat body 1 is worn stably while avoiding interference with the noise-canceling earmuffs 5.

[0044] In this embodiment, the cap body 1 is provided with a front edge, and the earplug box 6 is provided on both sides of the cap body 1 in the area near the root of the front edge.

[0045] Specifically, the position of the earplug box 6 is reasonably set according to the structure of the cap body 1 for easy access.

[0046] In this embodiment, the earbud case 6 is provided with a push-button lid.

[0047] Specifically, the push-button lid is simple and practical, preventing the loss of in-ear earbuds.

[0048] In this embodiment, a sound-insulating buffer layer is provided inside the cap body 1.

[0049] Specifically, the wearing comfort is improved by using a sound-absorbing buffer layer.

[0050] In this embodiment, a positioning post is provided on the base, and multiple positioning holes are provided on the platform.

[0051] Specifically, the positioning pins and holes facilitate quick and easy positioning, avoiding the difficulty of misalignment between the connecting seat 3 and the platform.

[0052] In this embodiment, the positioning post has an elliptical cross-section and is positioned at the center of the four bolts 7.

[0053] Specifically, the elliptical positioning post provides accurate positioning and can perform both positional and angular positioning.

[0054] This embodiment describes the use of a noise-protective safety helmet, taking its application on a construction site as an example:

[0055] By using the connecting seat 3 and the array holes, the noise-canceling earmuffs 5 are assembled to the helmet body 1, achieving noise reduction while ensuring the wearing of the safety helmet, thus protecting the safety of workers.

[0056] During installation, initial positioning is first performed using the positioning pins to prevent the four bolts 7 from not being aligned at the same time. Then, each bolt 7 is tightened to fix the connecting seat 3 and the row of holes 2.

[0057] If you wear the noise-canceling earmuffs 5 for a long time, you can rotate and fold them to store them behind your head or remove the connector 3. Then, use in-ear earplugs to relieve the pressure on your ears from wearing the noise-canceling earmuffs 5 for a long time, while ensuring a certain level of noise reduction.

[0058] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
