Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, specifically to a safety helmet liner adjustment and fixing structure. Background Technology

[0002] A safety helmet is a hat designed to protect the head from injuries caused by falling objects and other specific factors. It consists of a shell, liner, chin strap, and accessories. Safety helmets are widely used in construction and machining operations. Wearing a safety helmet correctly can effectively prevent head injuries from falling objects, injuries from impacts, mechanical damage, and injuries caused by hair contamination. While safety helmets vary in shape, material, and even color due to the specific needs of different jobs, their inner lining structure is generally the same. Several fixed shell sizes are available, and the depth of the liner is determined based on the shell size. The wearer then chooses the size that fits them comfortably.

[0003] Patent document CN221653705U discloses a standard-wearing safety helmet, including a helmet body and a chin strap. The helmet body includes a shell and an inner liner installed within the shell. The helmet also includes an elastic element installed within the helmet body, which supports the helmet on the top of the head. When the chin strap is fastened, the elastic element is pressed into the helmet body under the pressure of the head for proper helmet wearing. When the chin strap is not fastened, the elastic element cannot be pressed into the helmet body for proper helmet wearing. This utility model of the safety helmet makes a simple improvement on the existing structure. When the chin strap is not fastened, the elastic element prevents the helmet from being fully put on the head. Therefore, when wearing this helmet, the user must fasten the chin strap to prevent the helmet from slipping off, thus improving the helmet's safety performance.

[0004] However, existing technologies still have shortcomings: Existing safety helmets do not allow for easy adjustment of the liner to suit different head sizes. While a helmet liner is meant to provide safety and comfort, current liner options are difficult to adapt to different head shapes, reducing applicability and comfort. Some liner options are also prone to slipping, causing the helmet to become loose or too tight for people with different head shapes, reducing stability. This falls far short of current user requirements and makes the helmet inconvenient to use.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a safety helmet liner adjustment and fixing structure.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a safety helmet liner adjustment and fixing structure, including a helmet shell, wherein a buffer layer is provided inside the helmet shell, characterized in that: a tail wing adjustment piece, wherein the tail wing adjustment piece is disposed at one end inside the helmet shell; a tail wing fixing buckle, wherein the tail wing fixing buckle is disposed at one end of the buffer layer; a sweatband fixing piece, wherein the sweatband fixing piece is disposed at the other end inside the helmet shell; a sweatband fixing buckle, wherein the sweatband fixing buckle is disposed at both ends inside the helmet shell; and a liner adjuster, wherein the liner adjuster is disposed at one end inside the helmet shell.

[0008] Furthermore, the tail wing fixing buckle is slidably mounted on the tail wing adjusting plate.

[0009] Furthermore, both ends of the tail fin adjustment piece are provided with annular portions, which are slidably connected to both ends of the back of the liner adjuster.

[0010] Furthermore, the liner adjuster is provided with connecting straps at both ends, and the connecting straps are inserted through both ends of the tail fin adjusting plate.

[0011] Furthermore, the sweat-absorbing belt fixing plate has fixing holes at both ends, and the lining adjuster has a buckle fixedly connected to both ends. The buckle is inserted into the fixing hole and is used in conjunction with the sweat-absorbing belt fixing buckle.

[0012] Furthermore, a knob is provided at the center of the front of the lining adjuster.

[0013] The advantages of this invention compared to existing technologies are as follows: This invention, through the arrangement of a tail wing adjustment plate, tail wing fixing buckle, sweatband fixing plate, sweatband fixing buckle, and liner adjuster, allows for adjustment of the fixing position according to head size by adjusting the up-down position of the tail wing fixing buckle support rod on the tail wing adjustment plate. Adjusting the knob of the liner adjuster controls the tightening or loosening of the connecting strap, which in turn tightens or loosens the sweatband fixing plate, thus allowing for adjustment of the shape and size of the liner. This ensures that the cushioning layer of the helmet's inner liner can more effectively contact the user's head, allowing for precise adjustment of the liner's tightness according to head circumference. This ensures the helmet fits snugly and comfortably to different head sizes, preventing movement, reducing safety hazards, and making it very convenient to use. The helmet's design is thin and stylish, improving wearing comfort and stability, and enhancing its practicality. Attached Figure Description

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figures 1 to 12 As shown, this embodiment proposes a helmet liner adjustment and fixing structure, including a helmet shell 1, with a buffer layer 2 inside the helmet shell 1. The buffer layer 2 is the inner liner of the helmet and is made of EPS material, which is existing technology. Its core advantage lies in its excellent energy absorption and buffering capacity. It absorbs impact energy through compression deformation and distributes the force to the entire helmet, effectively reducing the local impact force on the head. At the same time, EPS material is very lightweight, which can significantly reduce the burden on the head and neck when wearing it and improve the comfort of wearing it for a long time.

[0030] The helmet shell 1 has a tail wing adjustment piece 3 at one end and a tail wing fixing buckle 4 at one end. The tail wing fixing buckle 4 is slidably installed on the tail wing adjustment piece 3. The tail wing adjustment piece 3 has a sliding hole at the lower end. The tail wing fixing buckle 4 has a support rod in the middle of one side. The support rod is T-shaped and passes through and is slidably connected in the sliding hole. The fixing position can be adjusted up and down according to the size of the head by adjusting the up and down position of the support rod of the tail wing fixing buckle 4 on the tail wing adjustment piece 3.

[0031] The helmet shell 1 has a strap adjuster 7 inside one end. The strap adjuster 7 has a knob in the middle of the front. The back of the strap adjuster 7 has two sliding holes. Several limiting blocks are evenly distributed on both ends of one side of the slider. The tail wing adjuster 3 has annular parts at both ends. The annular parts are slidably connected to the back of the strap adjuster 7. A Z-shaped slider is fixedly connected to one end of the annular part. The Z-shaped slider has a certain elasticity and is engaged and slidably connected in the sliding hole. The tail wing adjuster 3 is made of PP material, which is existing technology and can better fit the head, improving the comfort and fit of wearing the helmet.

[0032] The other end of the inside of the cap shell 1 is provided with a sweat-absorbing band fixing piece 5, and the two ends of the inside of the cap shell 1 are provided with sweat-absorbing band fixing buckles 6. Both ends of the lining adjuster 7 are provided with connecting straps, which are inserted into both ends of the tail wing adjusting piece 3. Specifically, the connecting straps are inserted into the inside of the ring-shaped part.

[0033] The sweatband fixing plate 5 has fixing holes at both ends, and the lining adjuster 7 has a buckle fixedly connected to both ends. The buckle is located at the end of the connecting belt and is inserted into the fixing hole. The buckle works with the sweatband fixing buckle 6. By passing the buckle at the end of the connecting belt through the fixing hole and fastening it with the sweatband fixing buckle 6, the connecting belt, the sweatband fixing plate 5 and the sweatband fixing buckle 6 are connected together, which is convenient for disassembly and assembly.

[0034] In practical implementation, this invention allows for adjustment of the vertical position of the tail wing fixing buckle 4 on the tail wing adjusting plate 3. This movement of the annular portion of the tail wing adjusting plate 3 within the sliding grooves at both ends of the back of the liner adjuster 7 allows for vertical adjustment of the fixing position according to head size. Adjusting the knob on the front of the liner adjuster 7 controls the tightening or loosening of the connecting strap. This adjustment of the connecting strap position tightens or loosens the sweatband fixing plate 5, thereby allowing for adjustment of the shape and size of the inner liner. The lower end of the helmet liner can be adjusted to fit the wearer's head, ensuring a snug fit. The separate buffer layer 2 allows for more effective contact with the user's head. Combined with the liner adjuster 7, it can be locked and fixed according to head size, improving the contact effect between the user's head and the buffer layer 2. This allows the user to precisely adjust the tightness of the liner according to head circumference, ensuring that the helmet fits snugly and comfortably to different head sizes, preventing movement and making the helmet more secure to wear. It is less likely to loosen, reducing safety hazards, and is easy to operate and use. It adapts to various head shapes, and its thin and stylish design improves the comfort and stability of wearing the helmet, enhancing its practicality.
