Description

Technical Field

[0001] This utility model relates to the field of explosion-proof helmet technology, specifically to a protective structure for an explosion-proof helmet. Background Technology

[0002] An explosion-proof helmet is a device used to protect the user's head. Its core function is to protect the user's head from impact and prevent or mitigate injury.

[0003] In order to protect the user's face, existing explosion-proof helmets often have a transparent protective layer on the face. This protective layer is usually flip-up and can be flipped open at any time as needed. However, because this protective layer can be flipped open, it may be opened in the event of a riot, which will greatly reduce the protective effect of the entire explosion-proof helmet. Therefore, an improved protective structure for explosion-proof helmets is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a protective structure for an explosion-proof helmet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for an explosion-proof helmet, comprising a helmet body, a fixing block fixedly disposed at the upper end of the helmet body, a protective frame movably disposed inside the fixing block via a bearing, a fixing mechanism for fixing the protective frame disposed between the helmet body and the protective frame, the fixing mechanism comprising fixing rivets, a limiting strap, a through hole, a limiting hole, and an L-shaped limiting piece, fixing rivets fixedly disposed on both sides of the lower end of the helmet body, a limiting strap fixedly disposed on the outer side of the fixing rivets, a through hole opened on the surface of the helmet body on one side of the fixing rivets, the limiting strap passing around the outer surface of the protective frame and passing through the through hole into the interior of the helmet body, a limiting hole opened on the surface of the limiting strap, and an L-shaped limiting piece fixedly disposed on the inner sidewall of the helmet body.

[0006] Preferably, the lower end of the helmet body is provided with a strap structure, which can be fixed to the wearer's chin. After the helmet body is worn, the strap structure can improve the overall wearing stability. At the same time, the strap structure can be adjusted to a certain degree of tightness as needed, so as to accommodate users of more body types.

[0007] Preferably, a protective face shield is fixedly mounted on the surface of the protective frame, which can ensure the wearer's field of vision when wearing the device.

[0008] Preferably, the helmet body has an internal cushioning layer, which can improve the wearing comfort of the helmet body.

[0009] Preferably, the L-shaped limiting piece is made of elastic metal material, which can ensure sufficient structural strength, and can be completely compressed towards the inner side wall of the helmet body after the wearer wears the helmet body, thereby improving the difficulty of disengagement of the limiting band from the outer side surface of the L-shaped limiting piece, and thus ensuring the fixing effect of the limiting band on the limiting protection frame.

[0010] Preferably, the outer side of the L-shaped limiting piece is wrapped with a soft pad, which can ensure the comfort of the L-shaped limiting piece and prevent the L-shaped limiting piece from scratching the face of the wearer.

[0011] Compared with the prior art, the protective structure of the protective helmet has the following beneficial effects:

[0012] 1. The protective frame can be adjusted as needed, and can be adjusted in the reversible and non-reversible states, thereby being applicable to various occasions to improve the protection effect of the device.

[0013] 2. After the wearer wears the helmet body, the L-shaped limiting piece can be compressed to be completely compressed towards the inner side wall of the helmet body, thereby improving the difficulty of disengagement of the limiting band from the outer side surface of the L-shaped limiting piece, and thus ensuring the fixing effect of the limiting band on the limiting protection frame.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: the protective structure of explosion-proof helmet, including helmet body 1, fixed block 2 is fixedly arranged on the upper end of the helmet body 1, protective frame 3 is movably arranged in the fixed block 2 by bearing, fixed mechanism for fixing protective frame 3 is arranged between the helmet body 1 and protective frame 3, the fixed mechanism includes fixed rivet 4, limiting strap 5, through hole 6, limiting hole 7, L-shaped limiting piece 8, fixed rivet 4 is fixedly arranged on the both sides of the lower end of the helmet body 1, limiting strap 5 is fixedly arranged on the outside of fixed rivet 4, through hole 6 is formed in the surface of the helmet body 1 on the side of fixed rivet 4, limiting strap 5 is passed through through hole 6 and enters the inside of helmet body 1 by the outside surface of protective frame 3, limiting hole 7 is formed in the surface of limiting strap 5, L-shaped limiting piece 8 is fixedly arranged on the inside side wall of the helmet body 1.

[0021] The lower end of the helmet body 1 is provided with binding structure 9, which can be fixed at the chin of the wearer, so that the overall wearing stability can be improved after the helmet body 1 is worn, and the binding structure 9 can be adjusted in tightness according to needs, so as to adapt to more users of different body shapes;

[0022] The surface of the protective frame 3 is fixedly provided with protective mask 10, which can ensure the observation field of view of the wearer after wearing the device;

[0023] The inside of the helmet body 1 is provided with buffer layer 11, which can improve the wearing comfort of the helmet body 1;

[0024] The L-shaped limiting piece 8 is made of elastic metal material, which can ensure sufficient structural strength, and can be completely compressed to the inside side wall of the helmet body 1 after the wearer wears the helmet body 1, so as to improve the difficulty of the limiting band 5 from being separated from the outside surface of the L-shaped limiting piece 8, so as to ensure the fixing effect of the limiting band 5 on the limiting protection frame 3.

[0025] The L-shaped limiting piece 8 is wrapped with a soft pad, and the L-shaped limiting piece 8 of the device will contact the face of the wearer, and the soft pad can ensure the comfort of the L-shaped limiting piece 8 and prevent the L-shaped limiting piece 8 from scratching the face of the wearer.

[0026] Working principle: When using the device, the protection frame 3 of the device can be adjusted as needed, and can be adjusted in the reversible and non-reversible states, so as to be suitable for use in various occasions, so as to improve the protection effect of the device. When the protection frame 3 is not needed to be turned over, the limiting band 5 is passed outside the protection frame 3, then passes through the through slot and enters the inside of the helmet body 1, and then the through hole 6 on the surface of the limiting band 5 is sleeved on the outside surface of the L-shaped limiting piece 8. At this time, the limiting band 5 is difficult to be separated from the L-shaped limiting piece 8 under tension, so as to prevent the protection frame 3 from being opened accidentally, so as to improve the protection safety of the device.

[0027] And when the device is used, after the wearer wears the helmet body 1, the L-shaped limiting piece 8 can be compressed to be completely compressed to the inside side wall of the helmet body 1, so as to improve the difficulty of the limiting band 5 from being separated from the outside surface of the L-shaped limiting piece 8, so as to ensure the fixing effect of the limiting band 5 on the limiting protection frame 3.
