Description

Technical Field

[0001] The utility model relates to the technical field of safety protection equipment, in particular to an inflatable safety helmet. Background Art

[0002] Safety helmets are widely used in various fields because they can protect the human head. Their main function is to protect the user's head, and to buffer, absorb shock and disperse impact force in the event of an accident, thereby avoiding damage to the head caused by external impacts and protecting life safety.

[0003] At present, the shell of common safety helmets is mostly made of ABS plastic material, which is characterized by rigid material, excellent mechanical properties, impact resistance and non-deformation. The liner is mostly made of EPS material, which has high density and good shock absorption effect. However, for such safety helmets, in order to achieve its safety performance, it is inevitable to increase the thickness of its shell and liner, thereby increasing its weight.

[0004] There are some inflatable helmets nowadays, but due to defects in the air chamber structure itself, they are very likely to be deformed and damaged when impacted by external force. However, the deformed and damaged air chambers of these inflatable helmets cannot be replaced. In this case, the helmet loses most of its protective effect and is difficult to effectively protect the user's head when impacted by external force. Utility Model Content

[0005] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide an inflatable safety helmet to improve the problem in the prior art that the air chamber of the inflatable helmet cannot be replaced after being deformed and damaged, so that the helmet can effectively protect the head and resist impact injuries to the head to a greater extent.

[0006] In order to solve the above technical problems, the utility model proposes an inflatable safety helmet, which adopts the following technical solutions:

[0007] An inflatable safety helmet comprises a headgear, an air cavity part and an air cavity part holder. There are two air cavity part holders, which are respectively mounted at two ends of the headgear. The air cavity part holder comprises a fixing part and a buckle part. The fixing part is fixedly connected to the headgear, and the buckle part is movably mounted relative to the fixing part. The two ends of the air cavity part are mounted between the fixing part and the buckle part.

[0008] Due to the characteristics of the air cavity component, it is relatively easy to be damaged. With this structure, the air cavity component can be easily replaced after being damaged, reducing the cost of use. The air cavity component is fastened to the headgear using an air cavity component fixer, which can effectively prevent the air cavity component from separating or slipping off the headgear.

[0009] Furthermore, one end of the fixing member and the fastening member is rotatably connected by a rotating shaft. A clamping protrusion is provided at the other end of the fastening member, and a clamping groove is provided at the corresponding position of the fixing member. The clamping protrusion is clamped in the clamping groove. The design of the buckle enables the rapid installation between the fixing member and the fastening member, and the strength is reliable, improving the structural stability between the components.

[0010] Furthermore, a sliding protrusion is provided on the lower side of the fixing member, and a sliding groove is provided on the lower side inside the fastening member. The sliding protrusion is slidably connected in the sliding groove. The fixing member and the fastening member are two separate parts, and the sliding groove and the sliding protrusion are clamped and installed, which is beneficial to quickly and accurately fix the air chamber member.

[0011] Furthermore, the headgear is a shock-absorbing shell. The shock-absorbing shell and the air chamber member together form a double shock-absorbing layer, and the double shock-absorbing layer is at least two completely identical parts. The air chamber member and the shock-absorbing shell serve as the primary shock-absorbing layer and the secondary shock-absorbing layer respectively. The shock-absorbing shell can be made of common shock-absorbing materials such as polystyrene foam. In the presence of the primary shock-absorbing layer, the shock-absorbing shell as the secondary shock-absorbing layer can be reduced in thickness to a certain extent, enabling the helmet to have good protection while reducing weight.

[0012] Furthermore, the various parts of the double shock-absorbing layer are fixedly connected by a telescopic device, and the telescopic device is set in the form of an accordion. During use, the telescopic device can be adjusted by pulling to change the size of the internal space of the helmet to make the helmet fit the user's head more closely, thereby reducing the gap between the helmet and the head to achieve a better shock-absorbing effect.

[0013] Furthermore, a repeatedly detachable structure is provided between the headgear and the air chamber member. The repeatedly detachable structure is a magic tape. The back of the air chamber member is adhered to the hook surface of the magic tape, and the outer side of the headgear is adhered to the fuzzy surface of the magic tape. The magic tape is a low-cost and good-adhesion reusable bonding device. Using the magic tape enables the air chamber member to be fixed to the headgear and can be disassembled at any time.

[0014] Furthermore, the air chamber member is provided with an air inlet, an air inlet passage, and an air chamber. The air inlet is provided at one end of the air inlet passage, and one end of the air chamber is communicated with the air inlet passage. An independent one-way air inlet valve is provided between any air chamber and the air inlet passage. The one-way air inlet valve enables gas to enter the air chamber from the air inlet passage but not to flow in the reverse direction. The air chamber bulges outwards in the inflated state. Since each independent air chamber is provided with a separate one-way air inlet valve, when a certain air chamber ruptures and loses pressure, the remaining air chambers can still play a protective role.

[0015] Furthermore, the air chamber is in the shape of a candied haws bunch, having a bulging part and a connecting part. When the bulging part is inflated, it bulges outward by at least one layer of outer diaphragm. The connecting part connects two adjacent bulging parts, and the bulging parts and the connecting parts of adjacent air chambers are arranged alternately. With such a structure, the size of the connecting part is small, which can fully reduce the deformation resistance. At the same time, for the air chamber in the shape of a candied haws bunch, two adjacent air chambers can be better approximated and fitted, and the protection effect is good.

[0016] Furthermore, the fastening member is internally provided with a long strip-shaped groove, and there are multiple such grooves. The connecting part of the air chamber member is fixed in the groove. The grooves correspond to the connecting parts of the air chamber member one by one in the fastened state, providing strong friction force to effectively prevent the air chamber member from slipping off.

[0017] Furthermore, the fastening member is internally provided with a plugging rod, the fixing member is provided with a plugging hole, and the edge of the air chamber member is provided with an opening. The plugging rod passes through the opening and is plugged in the plugging hole. Fixing the air chamber member on the wearing member through the opening on the air chamber member is a fixing method with low processing cost and good effect.

[0018] In summary, for such an inflatable safety helmet, a replaceable air chamber member is adopted. After being damaged, it can be replaced in time, reducing the use cost, enabling the helmet to effectively protect the head, and resisting the impact damage to the head to a greater extent.

Detailed implementation manners

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] As Figure 1 shown, an inflatable safety helmet includes a headgear 1, an air chamber member 2 and an air chamber member fixator 3. There are two air chamber member fixators 3, and the two air chamber member fixators 3 are respectively installed at both ends of the headgear 1. The air chamber member fixator 3 includes a fixing member 31 and a fastening member 32. The fixing member 31 is fixedly connected to the headgear 1, and the fastening member 32 is relatively movably installed with respect to the fixing member 31. Both ends of the air chamber member 2 are installed between the fixing member 31 and the fastening member 32.

[0028] Due to the characteristics of the air chamber member 2, it is relatively easy to be damaged. With this structure, it is convenient to replace the air chamber member 2 after it is damaged, reducing the use cost. Using the air chamber member fixator 3 to fasten the air chamber member to the headgear 1 can effectively prevent the air chamber member 2 from separating or slipping off the headgear 1.

[0029] As Figure 4 shown, an implementation manner of the air chamber member fixator is that one end of the fixing member 31 and the fastening member 32 is rotatably connected through a rotating shaft 33. The other end of the fastening member 32 is provided with a clamping protrusion 321, and a card slot 311 is provided at the corresponding position of the fixing member 31. There are multiple clamping protrusions 321 and card slots 311, and the multiple clamping protrusions 321 are fastened in the card slots 311. The design of the buckle enables the fixing member 31 and the fastening member 32 to be quickly installed, and the strength is reliable, improving the structural stability between components.

[0030] As Figure 5 shown, another implementation manner of the air chamber member fixator is that a sliding protrusion 312 is provided on the lower side of the fixing member 31, and a sliding groove 322 is provided on the lower inner side of the fastening member 32. The sliding protrusion is slidably connected in the sliding groove. The fixing member 31 and the fastening member 32 are two separate parts, and the sliding groove and the sliding protrusion are fastened and installed, which is beneficial to quickly and accurately fix the air chamber member 2.

[0031] Further, the headgear 1 is a shock-absorbing shell. The shock-absorbing shell and the air cavity member 2 together form a double buffer layer, and the double buffer layer is at least composed of two identical parts. The air cavity member 2 and the shock-absorbing shell serve as the primary buffer layer and the secondary buffer layer respectively. The shock-absorbing shell can be made of common shock-absorbing materials such as polystyrene foam. In the presence of the primary buffer layer, the shock-absorbing shell as the secondary buffer layer can be reduced in thickness to a certain extent, enabling the helmet to have good protective effects while reducing weight.

[0032] Further, each part of the double buffer layer is fixedly connected by a telescopic device 4, and the telescopic device 4 is set in the form of an accordion. During use, the telescopic device 4 can be adjusted by pulling, which can change the size of the internal space of the helmet to make the helmet fit the user's head more closely, thereby reducing the gap between the helmet and the head to achieve a better shock-absorbing effect.

[0033] As Figure 3 shown in the flat structure of the connection method between the air cavity member and the headgear, a repeatable detachable structure is provided between the headgear 1 and the air cavity member 2. The repeatable detachable structure is a magic tape 5. The back surface of the air cavity member 2 is adhered to the hook surface 51 of the magic tape, and the outer side of the headgear 1 is adhered to the loop surface 52 of the magic tape. The magic tape 5 is a repeatable bonding device with low cost and good sticking effect. Using the magic tape 5 enables the air cavity member to be fixed to the headgear and can be detached at any time.

[0034] As Figure 2 shown in the schematic diagram of the air cavity member structure, the air cavity member 2 is provided with an air inlet 21, an air inlet passage 22, and an air cavity chamber 23. The air inlet 21 is arranged at one end of the air inlet passage 22, and one end of the air cavity chamber 23 is communicated with the air inlet passage 22. An independent one-way air inlet valve 24 is provided between any air cavity chamber 23 and the air inlet passage 22. The one-way air inlet valve 24 allows gas to enter the air cavity chamber 23 from the air inlet passage 22 but does not allow reverse flow. The air cavity chamber 23 bulges outward in the inflated state. Since each independent air cavity chamber 23 is provided with a separate one-way air inlet valve 24, when a certain air cavity chamber 23 ruptures and loses pressure, the remaining air cavity chambers 23 can still play a protective role.

[0035] Further, the air cavity chamber 23 is in the shape of a candied haws bunch, having a bulging portion 231 and a connecting portion 232. When the bulging portion 231 is inflated, it bulges outward by at least one outer diaphragm 25. The connecting portion 232 connects adjacent two bulging portions 231, and the bulging portions 231 and the connecting portions 232 of adjacent air cavity chambers are arranged alternately. With such a structure, the size of the connecting portion 232 is small, which can fully reduce the deformation resistance. At the same time, for the air cavity chamber 23 in the shape of a candied haws bunch, adjacent two air cavity chambers 23 can be better approximated and fitted, and the protective effect is good.

[0036] Further, the engaging member 32 is internally provided with a plurality of elongated grooves 323, and the connecting portion 232 of the air chamber member 2 is fixed in the grooves 323. The grooves 323 correspond to the connecting portion 232 of the air chamber member one by one in the engaged state, providing strong friction force to effectively prevent the air chamber member 2 from slipping off.

[0037] Further, the engaging member 32 is internally provided with a plugging rod, the fixing member 31 is provided with a plugging hole, and the edge of the air chamber member is provided with an opening. The plugging rod passes through the opening and is plugged in the plugging hole. Fixing the air chamber member 2 on the wearing member 1 through the opening on the air chamber member 2 is a fixing method with low processing cost and good effect.

[0038] In summary, such an inflatable safety helmet adopts a replaceable air chamber member, which can be replaced in time after being damaged, reducing the use cost, enabling the helmet to effectively protect the head and resisting the impact damage to the head to a greater extent.

[0039] In short, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
