Description

Technical Field

[0001] This invention relates to the field of safety helmet technology, specifically to a novel safety helmet with multiple protective features. Background Technology

[0002] A safety helmet is a head protection device composed of a shell, liner, chin strap, and accessories, primarily used to protect against impacts from falling objects and prevent accidental collision injuries. Safety helmets are a "life shield" protecting workers' heads in industrial production, effectively reducing the risks of being struck by objects, mechanical collisions, and electric shocks by dispersing impact force and blocking falling objects. Safety helmets reduce the risk of head injury through cushioning, shock absorption, and stress dispersion. The gap between the shell and liner effectively reduces the transmission of impact force; standards require that the force transmitted to the headform not exceed 4900N, and that no fragments detach from the shell. Safety helmets are classified into general work (Class Y) and special work (Class T) categories, the latter including models with features such as electrical insulation, flame retardancy, and low-temperature resistance. Products must comply with the GB 2811-2019 national standard, with mandatory indicators including impact absorption performance and puncture resistance. The color selection of safety helmets follows principles of safety psychology; for example, yellow represents ordinary workers, red represents technicians or managers, blue represents technicians, and white represents supervisors or leaders, etc.

[0003] Currently, existing safety helmets have a relatively simple structure, mainly consisting of a shell, liner, and chin strap. Although they have a certain impact resistance, their protective structure is singular and cannot fully protect the head safety of workers in some high-risk environments, resulting in insufficient adaptability.

[0004] Therefore, there is a need for a new type of safety helmet that can provide strong protection and good adaptability with multiple layers of protection. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a novel safety helmet with multiple layers of protection. The helmet consists of a main body, an inner protective shell, and individual protective components, forming a multi-layered protective structure that can withstand strong impacts and protect the worker's head. Furthermore, the protective components can be easily detached to adapt to different working environments, demonstrating excellent safety and adaptability.

[0006] To achieve the above objectives, the present invention proposes the following specific solutions:

[0007] A novel safety helmet with multiple protection features includes a helmet body. A ring-shaped brim is fixedly fitted onto the lower outer wall of the helmet body. A protective assembly is movably fitted onto the lower outer side of the helmet body. The protective assembly includes a mounting ring, an arc-shaped support frame, and a protective arc plate. The mounting ring is movably fitted onto the lower outer side of the helmet body and is located above the ring-shaped brim. An arc-shaped support frame is fixed to the top surface of the mounting ring and is located on the outer side of the helmet body. Multiple hollow blocks are fixed to the outer wall of the arc-shaped support frame. Multiple protective arc plates are provided on the outer side of the arc-shaped support frame. A buffer block is fixed to the inner wall of the protective arc plate. One end of the buffer block is movably inserted into the inner side of the hollow block, and a spring is fixed to one end of the buffer block. The spring is located inside the hollow block, and one end of the spring is fixed to the outer wall of the arc-shaped support frame.

[0008] The safety helmet body is symmetrically provided with inner protective shells on its inner side. An inner liner is fixed to the inner wall of the inner protective shell. A fixing block is fixed to the lower outer wall of the inner protective shell. A connecting hole is provided in the middle of one side wall of the fixing block. A rotating groove is provided through the connecting hole at one end. A fixing plate is symmetrically fixed to the lower end of the safety helmet body. A threaded hole is provided at the lower end of the fixing plate. A drive screw is threaded to the inner side of the threaded hole. The drive screw passes through the threaded hole. A connecting post is fixed to one end of the drive screw. The connecting post passes through the connecting hole. A rotating disk is fixed to one end of the connecting post. The rotating disk is movably sleeved inside the rotating groove.

[0009] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, the mounting ring has symmetrical mounting holes on its top surface, and the annular brim has symmetrical threaded posts fixed on its top surface, with the threaded posts penetrating the mounting holes.

[0010] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, a threaded ring is threadedly connected to the outer side of the upper end of the threaded column, and the threaded ring is located above the mounting ring.

[0011] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, the safety helmet body has a fixing cylinder symmetrically fixed on the inner wall, and a through hole is provided in the middle of the outer wall of one side of the fixing cylinder, and the through hole communicates with the inner side of the fixing cylinder.

[0012] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, a fixing post is fixed to the outer wall of the inner protective shell, the fixing post passes through a through hole, and a limiting plate is fixed to one end of the fixing post, the limiting plate being located inside the fixing cylinder.

[0013] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, a sliding groove is provided on one side of the outer wall of the hollow block, and the sliding groove is in communication with the inner side of the hollow block.

[0014] As a preferred technical solution of a novel safety helmet with multiple protection according to the present invention, a sliding block is fixed to one side wall of the buffer block, and the sliding block is located inside the sliding groove.

[0015] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, a strap is provided below the inner protective shell, and the end of the strap is fixed to the lower end of the inner protective shell.

[0016] As a preferred technical solution of a novel safety helmet with multiple protections according to the present invention, the straps are woven elastic bands and the inner lining is made of elastic silicone material.

[0017] As a preferred technical solution of the novel safety helmet with multiple protections according to the present invention, the size of the rotating disk is adapted to the size of the rotating groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention uses a protective component installed on the outside of the safety helmet to enhance the protection of the worker's head. Multiple protective arc plates in the protective component can protect different parts of the worker's head. When a heavy object falls on the protective arc plate, the protective arc plate absorbs the impact force and protects the worker's head. The impact force is transmitted to the spring through the buffer block. The spring deforms under the force to dissipate the force, further reducing the injury to the worker's head. In addition, the two inner protective shells inside the safety helmet body are lined with elastic silicone pads, which can absorb the impact force again, thus forming multiple protective measures to protect the worker's head safety.

[0020] The mounting ring of the protective component of this invention is installed above the annular brim on the outside of the safety helmet body. It is fixed by using a threaded post passing through the inner side of the mounting hole on the mounting ring, and a threaded ring threadedly connected to the outer side of the threaded post. The threaded ring is tightened to press the mounting ring. The protective component can be disassembled simply by unscrewing the threaded ring from the threaded post. This allows the protective component to be removed and used in places where high-strength protection is not required, reducing the weight of the overall structure and making it easier for workers to wear. This improves the adaptability of this solution in different situations.

[0021] The present invention provides two inner protective shells on the inner side of the safety helmet body for wearing on the worker's head. The fixing block sidewall of the outer wall of the inner protective shell has a connecting hole, and one end of the connecting hole has a rotating groove. The drive screw is threaded to the inner side of the threaded hole on the fixing plate at the lower end of the safety helmet body. The connecting post at one end of the drive screw is movably connected to the inner side of the connecting hole, and the rotating disk at one end of the connecting post is movably sleeved on the inner side of the rotating groove. The fixing post on the outer wall of the inner protective shell passes through the through hole on the fixing cylinder of the inner wall of the safety helmet body. The drive screw and the fixing post ensure that the inner protective shell will not rotate or shake. Turning the drive screw controls the movement of the inner protective shell. When the two inner protective shells are on the worker's head, turning the drive screws on both sides will bring the two inner protective shells closer together, so that the inner liner fits against the worker's head, thereby preventing them from falling off during use. It can also accommodate workers with different head sizes, improving adaptability and practicality. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-8 As shown, the present invention provides the following technical solution: a novel safety helmet with multiple protections, including a safety helmet body 1, with an annular brim 11 fixedly sleeved on the lower outer wall of the safety helmet body 1. The annular brim 11 can provide a certain support for the mounting ring 31 and provide a fixed position for the threaded post 111, thereby improving stability.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, specifically, a protective component 3 is movably fitted onto the outer side of the lower end of the safety helmet body 1 to enhance the protection of the worker's head. The protective component 3 includes a mounting ring 31, an arc-shaped support frame 32, and a protective arc plate 33. The mounting ring 31 is movably fitted onto the outer side of the lower end of the safety helmet body 1, supports the arc-shaped support frame 32, and is used for the installation and removal of the protective component 3. The mounting ring 31 is located above the annular brim 11, and the arc-shaped support frame 32 is fixed to the top surface of the mounting ring 31. The arc-shaped support frame 32 supports and fixes the hollow block 321. The arc-shaped support frame 32 is located outside the safety helmet body 1. On the side, a hollow block 321 is fixed to the outer wall of the arc-shaped support frame 32. The hollow block 321 is used to connect the buffer block 331 and accommodate the spring 332. The buffer block 331 can move inside the hollow block 321. Multiple hollow blocks 321 are provided. A protective arc plate 33 is provided on the outer side of the arc-shaped support frame 32 to protect the worker's head and absorb the impact force. Multiple protective arc plates 33 are provided. A buffer block 331 is fixed to the inner wall of the protective arc plate 33. The buffer block 331 is used to transmit the impact force to the spring 332 and buffer and dissipate the force through movement. One end of the buffer block 331 is movably inserted into the inner side of the hollow block 321. A spring 332 is fixed to one end of the buffer block 31. The spring 332 can relieve force through elastic deformation to protect the safety of the workers. The spring 332 is located inside the hollow block 321, and one end of the spring 332 is fixed to the outer wall of the arc-shaped support frame 32. A sliding groove 322 is provided on one side of the outer wall of the hollow block 321. The sliding groove 322 restricts the movement range of the sliding block 333. The sliding groove 322 is connected to the inner side of the hollow block 321. A sliding block 333 is fixed to one side wall of the buffer block 331. The sliding block 333 is located inside the sliding groove 322. The sliding block 333 can ensure that the buffer block 331 does not move completely when it moves. The entire structure is detached from the inner side of the hollow block 321. This solution uses protective components 3 for enhanced protection. Multiple protective arc plates 33 can protect different parts of the worker's head. When a heavy object falls and hits the protective arc plate 33, the protective arc plate 33 can absorb the impact force and transmit the impact force to the spring 332 through the buffer block 331. The spring 332 dissipates the force through elastic deformation, further reducing the injury caused by the impact force to the worker. Thus, the protective components 3, together with the helmet body 1 and the inner protective shell 2, form a multi-layered protective structure, improving the overall protection and maximizing the protection of the worker's head safety.

[0036] Example 2

[0037] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, specifically, the top surface of the mounting ring 31 is symmetrically provided with mounting holes 311. When the mounting ring 31 is installed on the outside of the helmet body 1 and above the annular brim 11, the mounting holes 311 are used to connect the threaded post 111, thereby fixing the mounting ring 31. The top surface of the annular brim 11 is symmetrically fixed with the threaded post 111, which is used to cooperate with the threaded ring 112 to limit and fix the mounting ring 31. The threaded post 111 passes through the mounting hole 311, and the upper outer side of the threaded post 111 is threadedly connected to the threaded ring 112. The threaded ring 112 is located above the mounting ring 31 and can press the mounting ring 31 tightly, thereby preventing the mounting ring 31 from moving. The protective component 3 of this solution is installed through the mounting ring 31. The installation ring 31 is fitted onto the outer side of the lower end of the safety helmet body 1, above the ring-shaped brim 11. The threaded post 111 passes through the installation hole 311. After the threaded ring 112 is tightened onto the outer side of the threaded post 111, the threaded ring 112 can press the installation ring 31 from above to fix the installation ring 31, thus completing the installation and fixing of the protective component 3. By unscrewing the threaded ring 112 from the threaded post 111, the installation ring 31 can be disassembled, thereby removing the protective component 3. When workers are working in places with low risk, the protective component 3 can be left unused, thereby reducing the weight of the overall structure, reducing the burden on the worker's head, making it easier to wear, and enhancing adaptability to different environments.

[0038] Example 3

[0039] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, specifically, the safety helmet body 1 is symmetrically provided with an inner protective shell 2 on its inner side. The inner protective shell 2 can protect the worker's head inside the safety helmet body 1. An inner liner 22 is fixed to the inner wall of the inner protective shell 2. The inner liner 22 is made of elastic silicone material. The elastic silicone material of the inner liner 22 can deform to absorb impact force and can better fit the contour of the worker's head, making the wearing more stable. A fixing block 23 is fixed to the lower outer wall of the inner protective shell 2. The fixing block 23 is used to connect the inner protective shell 2 to the drive screw 13. A connecting hole 231 is provided in the middle of one side wall of the fixing block 23. The connecting screw 131 can rotate inside the connecting hole 231, so that the connecting hole 231 can normally drive the rotating disk 132 to rotate. A rotating groove 232 is provided at one end, which is used to accommodate the rotating disk 132. The rotating disk 132 can rotate normally inside the rotating groove 232. A fixing plate 12 is symmetrically fixed at the lower end of the safety helmet body 1. The fixing plate 12 can provide support for the drive screw 13. The lower end of the fixing plate 12 is provided with a threaded hole 121. The drive screw 13 is threadedly connected to the inside of the threaded hole 121, so that when the drive screw 13 rotates, it can move inside the threaded hole 121. The drive screw 13 is threadedly connected to the inside of the threaded hole 121. When the drive screw 13 rotates, it can drive the inner protective shell 2 to move. The positions of the two inner protective shells 2 are adjusted by using two drive screws 13 respectively. The drive screw 13 passes through the threaded hole 121 and drives the inner protective shell 2 to move. A connecting post 131 is fixed to one end of the moving screw 13. The connecting post 131 connects to the rotating disk 132 and can drive the rotating disk 132 to rotate. The connecting post 131 passes through the connecting hole 231, and the rotating disk 132 is fixed to one end of the connecting post 131. The rotating disk 132 is movably sleeved inside the rotating groove 232. The rotating disk 132 rotates inside the rotating groove 232 and can drive the fixed block 23 to move. The size of the rotating disk 132 is adapted to the size of the rotating groove 232. A strap 21 is provided below the inner protective shell 2. The end of the strap 21 is fixed to the lower end of the inner protective shell 2. The strap 21 is a woven elastic band. The strap 21 can be deformed to fit around the worker's chin to enhance the stability of the helmet body 1. This solution can achieve this by rotating the driving screw 13. The connecting column 131 rotates, which in turn drives the rotating disk 132 to rotate. The connecting column 131 rotates inside the connecting hole 231 on the side wall of the fixing block 23, and the rotating disk 132 rotates inside the rotating groove 232 inside the fixing block 23. Thus, when the driving screw 13 moves, the rotating disk 132 drives the fixing block 23 to move, and the fixing block 23 drives the inner protective shell 2 to move. Two driving screws 13 control the movement of the two inner protective shells 2 respectively. So when the two inner protective shells 2 are put on the worker's head, they can move closer to each other to clamp the worker's head, ensuring that the two elastic silicone inner pads 22 can fully fit the worker's head, thereby improving the stability of wearing the garment.It can also be adapted to the head size of different staff members, improving its adaptability.

[0040] Example 4

[0041] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 6 As shown, specifically, a fixing cylinder 14 is symmetrically fixed to the inner wall of the helmet body 1. The fixing cylinder 14 is used to accommodate the fixing post 24 and the limiting plate 241. The fixing post 24 and the limiting plate 241 can move inside the fixing cylinder 14. A through hole 141 is provided in the middle of the outer wall of one side of the fixing cylinder 14. The fixing post 24 extends into the inner side of the fixing cylinder 14 through the through hole 141 to complete the connection between the fixing post 24 and the fixing cylinder 14. The through hole 141 is in communication with the inner side of the fixing cylinder 14. A fixing post 24 is fixed to the outer wall of the inner protective shell 2. The fixing post 24 is inserted into the inner side of the fixing cylinder 14 through the through hole 141, which can prevent the inner protective shell 2 from rotating or shaking inside the helmet body 1 and improve stability. The fixing post 24 passes through the through hole 141. A limiting plate 241 is fixed to one end of the fixing post 24. Located inside the fixed cylinder 14, the limiting plate 241 cannot detach from the inside of the fixed cylinder 14 through the through hole 141, thus ensuring that the fixing column 24 will not detach from the inside of the fixed cylinder 14. In this solution, the fixing column 24 is inserted into the inside of the fixed cylinder 14 through the through hole 141, and the limiting plate 241 at one end of the fixing column 24 is located inside the fixed cylinder 14, ensuring that the connection between the fixing column 24 and the fixed cylinder 14 will not separate. This allows the fixing column 24 and the drive screw 13 to support the inner protective shell 2 from the upper and lower positions respectively and maintain the stability of the inner protective shell 2, ensuring that the inner protective shell 2 will not rotate or shake inside the safety helmet body 1. This allows the inner protective shell 2 to move stably along the horizontal direction when the drive screw 13 drives the inner protective shell 2 to move, resulting in good stability.

[0042] The working principle and usage process of this invention:

[0043] When in use, the two inner protective shells 2 inside the helmet body 1 are placed on the outside of the worker's head. The drive screws 13 on both sides are turned. The drive screws 13 drive the rotating disk 132 to rotate inside the rotating groove 232 on the fixing block 23 through the connecting column 131. When the drive screws 13 rotate inside the threaded hole 121 at the lower end of the fixing plate 12, they will move. This will drive the fixing block 23 to move through the rotating disk 132. The fixing block 23 will drive the inner protective shells 2 to move. The two drive screws 13 control the two inner protective shells 2 to move closer to each other, so that the two elastic silicone inner pads 22 fit tightly against the worker's head. The two inner protective shells 2 are stably clamped on the worker's head, fixing the helmet body 1. Then, the woven elastic strap 21 is put on the worker's chin to ensure that the helmet body 1 will not fall off.

[0044] When a heavy object falls from a height, it lands on the protective arc plate 33 in the protective component 3. The protective arc plate 33 can withstand the impact of the heavy object, and the impact force is transmitted to the spring 332 through the buffer block 331. The elastic deformation of the spring 332 further buffers and dissipates the force, which can dissipate most of the impact force and protect the safety of the worker's head. At the same time, the main body 1 of the safety helmet and the inner protective shell 2 can absorb the impact force again. The elastic silicone inner liner 22 dissipates the remaining impact force in the final stage, thereby completely ensuring the safety of the worker's head.

[0045] When working in low-risk areas, the enhanced protection of the protective component 3 is not required. By turning the threaded ring 112, the threaded ring 112 can be unscrewed from the threaded post 111, and the mounting ring 31 can be moved upward, so that the threaded post 111 is disengaged from the mounting hole 311, thereby disassembling the protective component 3. Only the safety helmet body 1 and the inner protective shell 2 are worn, thereby reducing the weight of the overall structure and reducing the burden on the worker's head.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
