Description

Technical Field

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

[0002] Currently, when wearing a helmet, most users will place a liner inside the helmet beforehand to separate the helmet from the head. However, these liners are mostly of a fixed shape and cannot fit everyone's head shape. They also cannot be folded and stored when carried, which makes them inconvenient to use.

[0003] For example, the utility model patent with patent publication number CN200987386Y discloses a safety helmet liner, which is composed of a pad body, a flexible ring plate and a spacer. The soft pad body has a thickness and several radially arranged extension plates are provided around the periphery. The flexible ring plate surrounds and connects the bottom ends of each extension plate, so that the pad body forms an inverted bowl shape. Each extension plate is provided with at least one spacer to be placed inside the safety helmet. The liner has a fixed shape, which cannot fit each user well and is inconvenient to carry and store.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a safety helmet liner. By combining a foldable fabric body with a flexible pressure strip, the shape of the helmet can be adjusted according to the user's head size, thus flexibly adapting to different users. It can also be quickly folded and stored after use.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A safety helmet liner includes a base fabric body, an adhesive component, and a flexible pressure strip. The middle part of the base fabric body is folded inward to form an inner fold. A first outer fold surface is formed at each of the left and right ends of the base fabric body. The front and rear ends of the two opposing surfaces of the first outer fold surfaces are respectively bonded together by the adhesive component. A flexible pressure strip is provided on the first outer fold surface along the length direction.

[0008] According to the above scheme, the first outer folding surface is folded outward to form a second outer folding surface, and the second outer folding surface is fixedly connected to the first outer folding surface by an adhesive component. This design further enhances the strength of the first outer folding surface.

[0009] According to the above scheme, the flexible pressure strip is provided on the second outer fold surface. This design allows the flexible pressure strip to hold the helmet in place when the first and second outer fold surfaces are opened outwards, quickly forming a hat shape and securing it to the inside of the helmet. When the liner is removed for reuse, it remains easy for the user to put it back on.

[0010] According to the above scheme, the length of the flexible pressure strip is less than or equal to the length of the second outer fold surface. This design ensures that the flexible pressure strip is positioned along the circumference of the bushing, thereby maximizing the circumferential shaping of the bushing in its open state.

[0011] According to the above scheme, the front and rear edges of the two opposing sides of the inner fold are respectively bonded together using adhesive. This invention is configured such that when the first and second outer folds are opened outwards, the inner fold unfolds simultaneously, forming downward folds at both the front and rear ends of the inner fold, creating a deep three-dimensional space. These folds maintain the unfolded shape of the inner fold and further enhance the overall structural strength of the bushing.

[0012] According to the above scheme, the front end of the first outer fold is arc-shaped or beveled. This design allows the front end of the bushing to form a shape that is narrower at the top and wider at the bottom, better adapting to conventional head shapes and improving wearing stability.

[0013] According to the above scheme, the rear end of the first outward folded surface is arc-shaped or oblique. This design allows the rear end of the bushing to form a shape that is narrower at the top and wider at the bottom, better adapting to conventional head shapes and improving wearing stability.

[0014] According to the above scheme, the adhesive component is a hot-melt wire. This design of the present invention is beneficial for the fixing and bonding of the bushing.

[0015] The working principle of this invention is as follows: In use, the user first unfolds the two outer folds of the liner outwards and pushes the inner fold upwards to form a hat shape. The user then puts it on their head, securing it in place with a flexible strip. The user can adjust the liner to fit their head size, ensuring it rests against the inside of the helmet. This effectively prevents hair from getting inside the helmet, achieving a cleanliness effect. After use, the liner is removed by simply pushing the outer folds inwards and the inner fold downwards to restore the liner to its flat, folded state. The user can then easily store and carry it.

[0016] The beneficial effects of this utility model are:

[0017] This invention features a combination of a foldable fabric body and a flexible pressure strip. When in use, simply unfold the first outer fold outwards and push the inner fold upwards to form a hat shape. It is convenient to use, maintains its shape well, and flexibly adapts to different users. After use, simply push the first outer fold inwards and the inner fold downwards for quick folding and storage. This liner is flexible and convenient to use, and is well-suited for hair care when wearing a safety helmet. Attached Figure Description

[0030] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 10As shown, the safety helmet liner of this utility model includes a base fabric body, an adhesive component 3, and a flexible pressure strip 4. The middle part of the base fabric body is folded inward to form an inner fold 21. A first outer fold surface 2 is formed at each of the left and right ends of the base fabric body. The front ends 23 and rear ends 24 of the two facing surfaces of the first outer fold surfaces 2 are respectively bonded together by the adhesive component 3. A flexible pressure strip 4 is provided along the length direction of the first outer fold surface 2. This design, through the combination of the foldable base fabric body and the flexible pressure strip 4, allows the shape of the liner 1 to be adjusted according to the user's head size, thus flexibly adapting to different users, and allows for quick folding and storage after use.

[0032] In this embodiment, the first outer fold surface 2 is folded outward to form a second outer fold surface 22, and the second outer fold surface 22 is fixedly connected to the first outer fold surface 2 by an adhesive member 3. This configuration further enhances the strength of the first outer fold surface 2.

[0033] In this embodiment, the flexible pressure strip 4 is disposed on the second outer folding surface 22. This design allows the flexible pressure strip 4 to hold the first and second outer folding surfaces 22 in place when they are opened outwards, quickly forming a hat shape and securing it to the inside of the helmet. This also makes it easy for the user to put the helmet back on when the liner is removed and needs to be reused.

[0034] In this embodiment, the length of the flexible pressure strip 4 is less than or equal to the length of the second outer fold surface 22. This design ensures that the flexible pressure strip 4 is arranged circumferentially along the bushing 1, thereby maximizing the circumferential shaping of the bushing 1 in its open state.

[0035] In this embodiment, the front and rear edges of the two opposing sides of the inner fold 21 are bonded together using adhesive members 3. This design ensures that when the first outer fold surface 2 and the second outer fold surface 22 are opened outwards, the inner fold 21 unfolds simultaneously, forming downward folded portions 211 at both the front and rear ends of the inner fold 21, creating a deep three-dimensional space. These folded portions 211 maintain the unfolded shape of the inner fold 21 and further enhance the overall structural strength of the bushing 1.

[0036] In this embodiment, the front end 23 of the first outer fold surface 2 is arc-shaped or beveled. This design allows the front end of the bushing 1 to form a shape that is narrower at the top and wider at the bottom, which can better adapt to conventional head shapes and improve wearing stability.

[0037] In this embodiment, the rear end 24 of the first outer fold surface 2 is arc-shaped or beveled. This design allows the rear end of the bushing 1 to form a shape that is narrower at the top and wider at the bottom, better adapting to conventional head shapes and improving wearing stability.

[0038] In this embodiment, the adhesive element 3 is a hot-melt wire. This design facilitates the fixing and bonding of the bushing.

[0039] The working principle of this utility model is as follows: In use, the user first unfolds the two outer folds 2 of the bushing 1 outwards and pushes the inner fold 21 upwards to form a hat shape. The user then puts it on their head, and the flexible pressure strip 4 secures the bushing 1 in its unfolded shape. The user can adjust it according to their head size, ensuring the bushing 1 fits snugly against the inside of the helmet. This effectively prevents hair from getting inside the helmet, achieving a cleanliness effect. After use, the bushing 1 is removed by simply pushing the two outer folds 2 inwards and the inner fold 21 downwards to restore the entire bushing 1 to its folded, flat state. The user can then store and carry it flexibly and conveniently.

[0040] However, this utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of this utility model.
