[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1:
[0029] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a conveniently adjustable combat protective gear, including an inner liner 1. A hook-and-loop fastener 2 is fixedly connected to the top of the inner liner 1. An outer liner 3 is provided on the top of the inner liner 1. By fixing the outer liner 3 at different positions of the inner liner 1, the protection range of the protective gear can be adjusted. A hook-and-loop fastener 4 is fixedly connected to the bottom of the outer liner 3. The hook-and-loop fastener 2 and the fastener 4 are interconnected, and the hook-and-loop fastener 2 and the fastener 3 cooperate to fix the relative positions of the inner liner 1 and the outer liner 2. A shoulder strap 6 is fixedly connected to the side of the inner liner 1 for wearing the inner liner 1. A waist belt 5 is fixedly connected to the side of the outer liner 3 to fix the position of the outer liner 3. A reinforcing component is installed on the inner side of the inner liner 1.
[0030] Reference Figure 1 and Figure 4 The reinforcing component includes an impact-resistant support layer 101, which is a glass fiber reinforced composite material. It is responsible for the overall distribution of force and structural support, helps to transmit impact force evenly, reduces local pressure concentration, and provides a stable support platform for internal materials. The impact-resistant support layer 101 is located on the inner side of the liner 1.
[0031] Reference Figure 1 The outer liner 3 is fixedly connected to the side of the groin protector 7, which effectively protects the athlete's groin. The top of the outer liner 3 is fixedly connected to the airbag 8, which can initially cushion the force on the athlete.
[0032] Example 2:
[0033] Reference Figure 4 In contrast to the above embodiments, this utility model also provides an embodiment in which the reinforcing component includes a buffer energy-absorbing layer 102. The buffer energy-absorbing layer 102 is made of polyurethane foam material, which has excellent energy absorption and impact dispersion capabilities. It can quickly absorb energy when impacted and effectively reduce the direct impact on the body. The buffer energy-absorbing layer 102 is disposed on the inner side of the liner 1.
[0034] Example 3:
[0035] Reference Figure 4 In contrast to the above embodiments, this utility model also provides an embodiment in which the reinforcing component includes a close-fitting comfort layer 103. The close-fitting comfort layer 103 is made of polyester fiber material and has soft, breathable and moisture-wicking functions, reducing friction and stuffiness during exercise and ensuring that the athlete remains comfortable even after wearing it for a long time. The close-fitting comfort layer 103 is disposed on the inner side of the lining 1.
[0036] Example 4:
[0037] Reference Figure 4 In contrast to the above embodiments, this utility model also provides an embodiment in which the reinforcing component includes an impact-resistant support layer 101, a buffer energy-absorbing layer 102, and a close-fitting comfort layer 103. The impact-resistant support layer 101 is made of glass fiber reinforced composite material, the buffer energy-absorbing layer 102 is made of polyurethane foam material, and the close-fitting comfort layer 103 is made of polyester fiber material. The impact-resistant support layer 101 is disposed on the inner side of the liner 1, the buffer energy-absorbing layer 102 is disposed on the inner side of the impact-resistant support layer 101, and the close-fitting comfort layer 103 is disposed on the inner side of the buffer energy-absorbing layer 102. Through the synergistic effect of the impact-resistant support layer 101, the buffer energy-absorbing layer 102, and the close-fitting comfort layer 103, the comfort, energy absorption, and support of the protective gear are improved, thus better protecting the safety of athletes in intense competition.
[0038] Working principle: Using the shoulder straps 6 on the inner lining 1, first put the inner lining 1 on the athlete's body, then adjust the outer lining 3 to the appropriate position, and stick the Velcro loop side 4 on the inner side of the outer lining 3 to the Velcro hook side 2 on the outer side of the inner lining 1 to fix the relative position of the outer lining 3 and the inner lining 1, while ensuring that the outer lining 3 can protect the athlete's key protective parts. Then tighten the waist belt 5 to achieve convenient adjustment of the protective position of the protective gear and improve the protective effect of the protective gear.
[0039] The impact-resistant support layer 101 of the glass fiber reinforced composite material can effectively disperse and balance the impact force, the cushioning and energy-absorbing layer 102 of the polyurethane foam material can quickly buffer the impact force when it is hit, reducing the risk of injury, and the close-fitting comfort layer 103 of the polyester fiber material ensures the comfort and good ventilation effect when the athlete is in direct contact, and enhances the support and durability of the overall structure. With the combination of the impact-resistant support layer 101, the cushioning and energy-absorbing layer 102 and the close-fitting comfort layer 103, comfort, energy absorption and support are integrated, which can better protect the safety of athletes in intense competition.
