[0028] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0029] according to Figure 1-8 As shown, the present embodiment proposes an ultralight bulletproof life jacket, comprising a life jacket front piece 1, a life jacket back piece 2, a first connecting belt 3 and a second connecting belt 4, the life jacket front piece 1 and the life jacket back piece 2 are symmetrically arranged front and back, shoulder straps 5 are respectively arranged on both sides of the upper end of the life jacket back piece 2, one end of the shoulder strap 5 is detachably connected to the front upper end of the life jacket front piece 1 through a first Velcro, first connecting belt 3 and second connecting belt 4 are respectively arranged on both sides of the lower end of the life jacket back piece 2, one end of the first connecting belt 3 and the second connecting belt 4 are connected through a second Velcro 6, an interlayer 7 is arranged on the inner side of the life jacket front piece 1 and the life jacket back piece 2, an ultra-high molecular polyethylene non-woven fabric lining 8 is detachably arranged inside the interlayer 7, a bending line 9 is arranged on the ultra-high molecular polyethylene non-woven fabric lining 8, and a plurality of groups of bending lines 9 are arranged. A third Velcro 10 is provided in the opening at the lower end of the interlayer 7; when the ultra-light bulletproof life jacket of the present invention is worn, firstly, the first connecting belt 3 and the second connecting belt 4 are kept in a separated state, and the shoulder strap 5 is kept to connect the life jacket front piece 1 and the life jacket back piece 2 together, at this time, the user can put the life jacket on the head from between the life jacket front piece 1 and the life jacket back piece 2, and then the first connecting belt 3 and the second connecting belt 4 are wound from both sides of the life jacket back piece 2 to the front side of the life jacket front piece 1 and connected together by the second Velcro 6, at this time, the life jacket can be worn;

[0030] The life jacket front piece 1 and the life jacket back piece 2 have the same structure, both include a base layer 22, an inflatable interlayer 23 and an outer decorative layer 24, an inflatable interlayer 23 is provided on the outer side of the base layer 22, an outer decorative layer 24 is provided on the outer side of the inflatable interlayer 23, an automatic air pump 25 is provided on the outer side wall of the first connecting belt 3, and the automatic air pump 25 is connected to the inflatable interlayer 23. By configuring the life jacket front piece 1 and the life jacket back piece 2 to consist of a base layer 22, an inflatable interlayer 23 and an outer decorative layer 24, the life jacket of the present invention can have buoyancy after being inflated by the automatic air pump 25, can provide buoyancy in an emergency on water, and can be uninflated at ordinary times, so as to improve the wearing comfort of the life jacket, and the configuration of the outer decorative layer 24 can protect the inflatable interlayer 23 by the outer decorative layer 24 to avoid damage and leakage during use.

[0031] The inner side of the shoulder strap 5 is provided with a sponge anti-wear lining 11, and the top of the shoulder strap 5 is provided with a connection seat 12, and a warning light 13 is provided in the connection seat 12. The provision of the sponge anti-wear lining 11 can prevent the shoulder strap 5 from rubbing against the user's shoulders, and can buffer a certain sense of weight caused by wearing a life jacket; traditional life jackets mostly play a warning role by providing reflective strips on the surface, but for special use environments (such as use environments that require hiding), the reflective strips will expose the user's position. The present invention provides a warning light 13 in the connection seat 12 at the top of the shoulder strap 5, and can be turned on to warn when a warning is needed, which can adapt to different use environments and has high flexibility.

[0032] The inner side of the second connection belt 4 is detachably connected to the lower front end of the life jacket front piece 1 through the fifth Velcro 14. The present invention can further improve the stability of the life jacket front piece 1 and the life jacket back piece 2 after being connected through the first connection belt 3 and the second connection belt 4 by providing the fifth Velcro 14. Specifically, when the first connection belt 3 and the second connection belt 4 are wound from both sides of the life jacket back piece 2 to the front side of the life jacket front piece 1, the third third Velcro 14 of the second connection belt 4 is first connected to the lower front end of the life jacket front piece 1, and then the first connection belt 3 is connected to the second connection belt 4 by the second Velcro 6.

[0033] The front upper end of the life jacket front piece 1 is provided with a storage pocket 15, and the storage pocket 15 is provided in a plurality of groups. The life jacket front piece 1 above the plurality of storage pockets 15 is provided with a pocket cover 16, and one end of the pocket cover 16 is detachably connected to the front of the storage pocket 15 through a sixth Velcro 17. The plurality of storage pockets 15 can be used to store items separately, which can improve the storage performance of the life jacket.

[0034] A sealing sheet 18 is provided at the opening at the lower end of the interlayer 7, and one end of the sealing sheet 18 is detachably connected to the lower end of the front face of the interlayer 7 through a fourth Velcro 19. The sealing sheet 18 and the fourth Velcro 19 can further improve the sealing performance of the opening at the lower end of the interlayer 7, thereby preventing the ultra-high molecular weight polyethylene non-woven fabric lining 8 from falling out of the interlayer 7.

[0035] A first magnetic sheet 20 is symmetrically arranged on the upper part of the interlayer 7, and a second magnetic sheet 21 adapted to the first magnetic sheet 20 is arranged on the upper end of the ultra-high molecular polyethylene non-woven fabric lining 8. By magnetically connecting the first magnetic sheet 20 inside the interlayer 7 with the second magnetic sheet 21 on the ultra-high molecular polyethylene non-woven fabric lining 8, it is possible to prevent the ultra-high molecular polyethylene non-woven fabric lining 8 from wrinkling inside the interlayer 7 due to the existence of the bending line 9, so that the ultra-high molecular polyethylene non-woven fabric lining 8 can be correctly laid flat in the interlayer 7.

[0036] The inflatable interlayer 23 forms a first chamber 26 and a second chamber 27, wherein the first chamber 26 is located below the inflatable interlayer 23, and the second chamber 27 is located above the first chamber 26. The second chamber 27 has a plurality of inflatable cavities 2701, and an air intake hose 28 is provided inside the first chamber 26. One end of the inflatable hose 28 is connected to the output end of the automatic air pump 25, and a soft branch pipe 29 is provided on the inflatable hose 28. The number and position of the soft branch pipe 29 are adapted to the number and position of the inflatable cavities 2701, and one end of the soft branch pipe 29 is connected to the inside of the inflatable cavities 2701. The above arrangement makes the plurality of inflatable cavities 2701 independent of each other, and the inflatable interlayer 23 will not be completely ineffective after a single inflatable cavity 2701 is damaged, thereby improving the protective power of the life jacket of the present invention.

[0037] A further improvement is that a storage bag 30 is provided on the outer side wall of the first connecting belt 3, the automatic air pump 25 is arranged inside the storage bag 30, and a zipper is provided on the upper end of the storage bag 30. The automatic air pump 25 is arranged externally, specifically, arranged on one side of the entire life jacket, so that the setting of the automatic air pump 25 does not affect the wearing and the user's actions.

[0038] The side wall of the inflatable interlayer 23 is made of at least two layers of buoyancy material, and the thickness of the buoyancy material is 0.3-0.5 mm. The buoyancy material of the present invention can be made of any one of polyvinyl chloride (PVC), polystyrene (EPS), polyurethane (PU), and polyethylene (PE). Polyvinyl chloride (PVC) has excellent weather resistance and chemical corrosion resistance; polystyrene (EPS) has a large output, a wide density range, a relatively low price, and is basically a closed-cell structure with fine pores, more than 90% gas, excellent thermal insulation, and extremely low water absorption. It is an important material for making life jackets; polyurethane (PU) has excellent elasticity and wear resistance; polyethylene (PE), especially high-density polyethylene (HDPE) foam plastics, has good buoyancy and water resistance, so as the side wall of the inflatable interlayer 23, it can ensure stable buoyancy and is not easy to be damaged.

[0039] The beneficial effects of the present invention are as follows: the present invention can detachably install an ultra-high molecular polyethylene non-woven fabric lining 8 in the interlayer 7 arranged on the inner side of the life jacket front piece 1 and the life jacket back piece 2. The ultra-high molecular polyethylene non-woven fabric has extremely high strength and modulus, can withstand large external forces without being easily damaged, and has the advantage of being light in weight. The present invention arranges multiple groups of bending lines 9 on the ultra-high molecular polyethylene non-woven fabric lining 8, so that the ultra-high molecular polyethylene non-woven fabric lining 8 can be bent to adapt to the user's bending and other actions, thereby effectively improving the wearing sensitivity; the life jacket of the present invention has buoyancy after being inflated by the automatic air pump 25, can provide buoyancy in an emergency on the water, and can be uninflated at ordinary times, so as to improve the wearing comfort of the life jacket; the present invention arranges the life jacket to be composed of the life jacket front piece 1, the life jacket back piece 2, the first connecting belt 3, the second connecting belt 4 and the shoulder strap 5, and the main parts are all connected by Velcro, so that the multiple main parts of the entire life jacket can be quickly separated and are easy to wear.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
