Description

Technical Field

[0001] This invention relates to the field of safety protective equipment technology, and in particular to a multi-purpose safety helmet. Background Technology

[0002] Safety helmets are essential head protection equipment for workers in industrial and mining enterprises, construction sites, and outdoor work environments. Their primary function is to withstand external impacts and protect workers' heads from injuries caused by collisions, falling objects, etc. They have a wide range of uses and are used in various scenarios. Currently, safety helmets on the market are typically made of ABS plastic, a material with sufficient strength and toughness to meet basic impact protection requirements. To prevent secondary injuries to workers' heads from the hard helmet shell when subjected to external impacts, existing safety helmets are equipped with internal fabric cushioning straps. A certain space is reserved between the cushioning straps and the top of the helmet as a buffer area, effectively absorbing impact force. In addition, safety helmets are also equipped with chin straps, which workers can tighten to prevent the helmet from falling off during work, further ensuring safety.

[0003] Although existing safety helmets can provide basic head impact protection, their limited functionality is becoming increasingly apparent in actual work, failing to meet the diverse protection needs of workers in different working environments. Specifically, they have the following shortcomings: 1. Lack of headlamp functionality: In poorly lit work environments, workers need to carry additional lighting tools. Using a handheld flashlight occupies one hand, affecting operational flexibility and causing inconvenience. While there are dedicated headlamps on the market designed for safety helmets, these often use elastic bands to secure them. Over time, these bands age and lose elasticity, causing the headlamp to loosen and fall off. Some headlamps require hooks to be attached to the helmet's outer edge for further fixation, which is not only cumbersome but also detracts from the helmet's overall appearance.

[0004] 2. Lack of ear protection: For workers who need to work outdoors in winter, especially in cold northern regions, existing ordinary safety helmets do not have ear protection devices. Workers' ears are exposed to low temperatures for extended periods, making them highly susceptible to frostbite. Although there are cotton safety helmets specifically designed for winter outdoor work on the market, if workers switch to indoor work, they need to switch to ordinary safety helmets. Frequent changes are not only cumbersome but may also delay work time.

[0005] 3. Lack of earplug storage: In high-noise work environments, noise can severely damage workers' hearing, so workers need to wear earplugs for hearing protection. However, existing safety helmets do not have a dedicated area for storing earplugs, causing workers to frequently forget to bring them or lose them while carrying them, making it impossible to protect their hearing in a timely manner and posing a safety hazard of hearing loss.

[0006] 4. Lack of dust protection: In dusty workplaces, existing safety helmets only protect the head from impact and cannot prevent dust from entering the face, mouth, and nose of workers. Long-term inhalation of dust can harm the respiratory health of workers. Although there are dedicated dust-proof safety helmets on the market, these helmets are only suitable for single scenarios with high dust concentrations. When used in ordinary workplaces, their fixed dust curtains can be cumbersome, especially in summer, as they can affect ventilation and heat dissipation, causing workers to feel stuffy and hot. Therefore, workers need to frequently change safety helmets in different scenarios, which is cumbersome.

[0007] In summary, existing safety helmets are functionally limited, providing only basic head impact protection and failing to simultaneously meet diverse operational needs such as lighting, ear warmth, earplug storage, and dust protection. Workers must frequently change helmets for different environments, impacting work efficiency. Therefore, developing a multi-purpose safety helmet that integrates multiple protective functions, can be switched on demand, and eliminates the need for frequent replacements has become a pressing technical challenge in this field.

[0026] Example A multi-purpose safety helmet, such as Figure 1 As shown, it includes a hat body 1, on which a headlamp assembly 2, an earmuff assembly 3, an earplug assembly 4, and a dustproof curtain assembly 5 are provided. The specific details are as follows: The cap body 1 is made of high-strength ABS material, possessing excellent impact and puncture resistance. The inner side of the cap body 1 has a cushioning pad to enhance wearing comfort and cushioning effect. The front of the cap body 1 has a visor 101, which is used to shield the user's face from sunlight, rain, and debris. Figure 7 and Figure 11 As shown, a hatband 102 is also provided on the hat body 1. A headlamp assembly 2 is provided on the outer wall of the cap body 1 above the brim 101, and the headlamp assembly 2 is positioned at a distance from the brim 101. The headlamp assembly 2 is detachably connected to the cap body 1 via a first connector, which includes a headlamp slot 6 and a headlamp plate 7 fixed to the cap body 1, such as... Figure 2 As shown, the headlamp slot 6 consists of two opposing side plates 601 fixed to the outer wall of the headgear 1. The opposing sides of the two side plates 601 are respectively provided with grooves 602 with openings at both ends, and the grooves 602 are arranged vertically. Figure 3 As shown, the headlamp mounting plate 7 includes a mounting plate 701, which has two mounting holes 7011. A limiting plate 702 is provided on the top of the mounting plate 701. The length of the limiting plate 702 is greater than the length of the mounting plate 701 and also greater than the distance between the two side plates 601. Hooks 703 are provided at both ends of the limiting plate 702. The hooks of the two hooks 703 are arranged oppositely and are spaced apart from the mounting plate 701.

[0027] During installation, insert the headlamp retaining plate 7 into the grooves 602 of the two side plates 601 until the limiting plate 702 is flush with the top of the two side plates 601. At this point, the hook 703 engages with the bottom of the side plates 601 (e.g., Figure 4 As shown, this achieves a stable connection between the headlamp mounting plate 7 and the headlamp slot 6; during disassembly, simply pinch the two hooks 703 together to remove the headlamp mounting plate 7 from the groove 602, and then disassemble the headlamp assembly 2. The operation is convenient. The headlamp assembly 2 in the prior art includes a strip headlamp (such as...)

The movable hinge 303 is connected to the fixed hinges 302 via a through rod 304. The damping hinge enables the earpiece 301 to rotate flexibly (e.g., ...). Figure 11 As shown), and can be fixed at any angle. When working indoors, the earcups 301 are not needed; they can be flipped up. Figure 11 (The dotted line in the image) When working outdoors in colder conditions, the earpiece 301 can be temporarily folded down. Figure 11 (The solid line part in the text) is very convenient to use.

[0029] Users can adjust the earcups 301 according to their wearing needs to ensure that the earcups 301 fit the ears, improving the warmth and wearing comfort. The installation and removal methods of the earcup clips 9 and earcup slots 8 are the same as those of the headlamp clips 7 and headlamp slots 6, making the operation simple. An earplug assembly 4 is provided on the right rear side of the outer wall of the cap body 1. The earplug assembly 4 is detachably connected to the cap body 1 via a third connector. The third connector includes an earplug slot 10 and an earplug plate 11 fixed to the cap body 1, such as... Figure 12 As shown, the structure of the earbud slot 10 is the same as that of the headlamp slot 6, as follows: Figure 13 As shown, the earplug holder 11 has the same structure as the headlamp holder 7, and the mounting plate of the earplug holder 11 has mounting holes. Figure 14 As shown, the earbud assembly 4 includes a storage box 401 with an openable lid. The storage box 401 is made of waterproof material. Earbuds 402 are placed inside the storage box 401. Two fixing hooks 403 are provided on the side wall of the storage box 401. The fixing hooks 403 are integrally formed with the storage box 401 and are engaged in the mounting holes of the earbud holder plate 11 (e.g., Figure 15 As shown), a stable connection is achieved between the storage box 401 and the earplug holder 11; the installation and removal methods of the earplug holder 11 and the earplug slot 10 are the same as those of the headlamp holder 7. The bottom edge of the helmet body 1 is equipped with a detachable dust curtain assembly 5. The dust curtain assembly 5 is used to block dust and debris from entering the user's face and neck, making it suitable for dusty work environments. The dust curtain assembly 5 includes a dust curtain 501, which is made of a waterproof and dust-proof flexible material, such as... Figure 16 As shown, the dust curtain 501 has a trapezoidal structure that is narrower at the top and wider at the bottom, which can better cover the neck and shoulders of the staff, improving the dust protection effect and wearing comfort; the top of the dust curtain 501 has multiple magnetic buckles 502 along its length, which are evenly distributed, and the bottom edge of the cap body 1 has magnetic strips 503 (such as... Figure 17 As shown, the magnetic strip 503 is fixedly connected to the cap body 1, and the magnetic buckle 502 is magnetically connected to the magnetic strip 503, so as to realize the quick installation and removal of the dust curtain 501. After removal, the dust curtain 501 can be cleaned or replaced, which is convenient to operate. In this embodiment, the headlamp slot 6, earmuff slot 8 and earplug slot 10 have the same structure, and their bottoms are all left with a certain distance from the brim of the hat, so that when the user takes out the corresponding card, he can pinch the hook on the card.

[0030] The headlamp mounting plate 7, earmuff mounting plate 9, and earplug mounting plate 11 have basically the same structure, with only differences in the setting of mounting holes depending on the different adapter components. This unified structural design simplifies the production process, reduces manufacturing costs, and makes the installation and disassembly of each component consistent, thus improving the user's ease of operation. In certain special cases, a warning light can be installed at the back of the helmet, with the warning light configured in the same way as the headlamp assembly.

[0031] When using the multi-purpose safety helmet provided by this invention, the user can choose to install corresponding auxiliary components according to the needs of the work scenario: when working at night or in low light, the headlamp component can be installed to provide illumination; in low-temperature environments, the earmuffs can be used to keep the ears warm; in noisy environments, earplugs can be used to reduce noise; in dusty environments, the dust curtain component can be installed to block dust; when a certain component is not needed, it can be removed to reduce the weight of the safety helmet and improve wearing comfort. The connection structure of each component is stable and easy to disassemble, which can effectively improve work efficiency and safety.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
