[0033] Embodiment 1
[0034] As Figures 1 to 4 The first embodiment of the present application is shown, which discloses an inner lining type safety helmet, comprising a helmet shell, a plurality of air holes are formed in the helmet shell, characterized in that the helmet shell is an inner lining type helmet shell 1, the air holes comprise a plurality of first air holes 2 arranged at the forehead part of the inner lining type helmet shell 1, a plurality of second air holes 3 arranged at the top of the head of the inner lining type helmet shell 1, a plurality of third air holes 4 arranged at the back of the head of the inner lining type helmet shell 1, and a plurality of fourth air holes 5 symmetrically arranged at the temporal bone parts of the inner lining type helmet shell 1.
[0035] The present embodiment is different from the previous double-layer safety helmet, which only has one helmet shell monomer, and is an inner lining type helmet shell 1, which can fit the head better and occupy less space, and the outer part of the inner lining type helmet shell 1 can also wear ordinary workshop hats, without wearing traditional hard outer helmet shell, which is not only beautiful and practical, but also can be worn in special production workshops or laboratories such as automobile production; secondly, a plurality of air holes are arranged at different parts of the inner lining type helmet shell 1, which greatly increases the air permeability, and when used with ordinary workshop hats, it can not only ensure the fit, but also have good air permeability.
[0036] In the present embodiment, the inner lining type helmet shell 1 is an ABS hard helmet shell. The inner lining type helmet shell 1 of the present embodiment is made of ABS material, which has excellent impact resistance, realizes lightweight and also has good protection performance. The main production method of the existing inner lining helmet shell is injection molding, which not only needs to design the mold opening, but also needs to debug the injection molding machine. If the structure of the helmet shell changes, the injection molding parameters and mold structure will change, resulting in more waste of raw materials and increasing the production cost. The inner lining type helmet shell 1 introduced in the present embodiment is made of ABS material, which can be produced and formed by 3D printing, which not only greatly reduces the production cost, but also has more flexible adjustment strategy. If the size of the helmet shell needs to be adjusted, it only needs to input the parameters into the 3D printer to quickly print and form.
[0037] like Figure 2 As shown, the inner liner cap shell 1 also has several evenly distributed opening slots 11 on its periphery. The opening slots 11 open at the brim of the inner liner cap shell 1 and extend towards the top of the inner liner cap shell 1. The opening slots 11 on the periphery allow the entire inner liner cap shell 1 to have better tolerance and a certain amount of fine-tuning space after wearing, so that it can be compatible with different head circumference sizes.
[0038] like Figure 2 As shown, both the second ventilation hole 3 and the fourth ventilation hole 5 are rectangular strip-shaped holes, and through holes are also opened on the sidewalls between two adjacent second ventilation holes 3. The through holes on the sidewalls between adjacent second ventilation holes 3 form a double-layer support structure. The double-layer support structure can improve the cushioning performance at the top of the head, and at the same time, it can provide more breathability while ensuring mechanical performance, thereby improving the user's comfort when wearing it.
[0039] like Figure 2 and 3 As shown, both the first vent 2 and the third vent 4 are circular through holes.
[0040] like Figure 4 As shown, the inner lining cap shell 1 has hook-shaped openings 12 on the back of the head and on both sides of the temporal bone. In workshops, there is often a lot of noise, so workers need to wear earplugs. The hook-shaped openings 12 are designed not only to secure the outer workshop cap's drawstring when wearing it, increasing the stability of the connection between the inner lining and the outer cap, but also to serve as a connection point for the earplug cord, making it easy to hang the earplugs and preventing them from being lost.
[0041] Example 2
[0042] This embodiment is similar to Embodiment 1, except that in this embodiment:
[0043] like Figure 5 and Figure 6 As shown, the inner-lined helmet also includes an adjustable strap 6, with both ends of the adjustable strap 6 connected to the temporal bone portion on both sides of the inner-lined helmet shell 1. The adjustable strap 6 can adjust the tightness to improve stability and accommodate different users.
[0044] like Figure 7 and Figure 8As shown, the inner-lined safety helmet also includes an eye shield structure 7, which includes a connector 71 and eyeglasses 72. The connector 71 is detachably connected to the forehead portion of the inner-lined helmet shell 1. A slot 711 is provided on the connector 71, and one end of the eyeglasses 72 is engaged in the slot 711. A first magnetic element is provided in the slot 711, and a second magnetic element 721 is provided at the end of the eyeglasses 72 that is engaged with the connector 71. In this embodiment, the inner-lined helmet shell 1 has a multi-modal design. Adding the eye shield structure 7 protects the wearer's eyes, eliminating the need to separately purchase protective glasses and earmuffs from a cost-effectiveness perspective. The eyeglasses 72 connected to the eye shield structure 7 can be disassembled and replaced, for example, with protective lenses, UV-protective lenses, or lenses that protect against welding arc light. Different lenses can be worn in different working environments, providing eye protection for the wearer in more work areas and also providing head protection.
[0045] Example 3
[0046] This embodiment is similar to Embodiment 1, except that in this embodiment:
[0047] like Figure 7 and Figure 3 As shown, the connector 71 is provided with a buckle 713, and the forehead part of the inner liner cap 1 is provided with a buckle hole 13 that cooperates with the buckle 713.
[0048] like Figure 7 As shown, the connector 71 is also provided with a third magnetic 714, and the forehead part of the inner cap shell 1 is provided with a fourth magnetic 714 that cooperates with the third magnetic 714.
[0049] It should be noted that the connection between the eye mask structure 7 and the inner lining shell is a dual connection method of buckle 713 and magnetic attraction. The connection between the connector 71 in the eye mask structure 7 and the glasses 72 is magnetic fixation. Compared with the buckle 713 connection, the magnetic connection is simple and efficient, with strong magnetic fixation force and convenient disassembly and replacement between parts.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
