Embodiment 1

[0029] Basic as attached figure 1 , Attached figure 2 And image 3 Shown: a water lifejacket, including a lifejacket body 1, the top of the lifejacket body 1 is integrally formed with a rotatable neck guard 2, that is, the lower end of the neck guard 2 is integrally formed with the lifejacket body 1, and the upper end of the neck guard 2 Two fixed straps 3 are suspended and connected; two plackets of the lifejacket body 1 are fixed with guide blocks 4 for the fixing belt 3 to pass through; both sides of the lifejacket body 1 are fixed at the waist position with several pairs The auxiliary block 16 guided by the fixing belt 3. The end of the left fixing strap 3 away from the collar 2 is connected with a positioning member 5, and the end of the right fixing strap 3 away from the neck protector 2 is connected with a fastener 6 that is clamped with the positioning member 5.

[0030] A swing arm 7 is symmetrically hinged on the positioning member 5 and the fastener 6, and a first ela...

Embodiment 2

[0037] Basic as attached Figure 4 As shown, the structure and implementation of the second embodiment is basically the same as that of the first embodiment. The difference is that the bottom of the lifejacket body 1 is provided with a leg fixing mechanism symmetrically, and the leg fixing mechanism includes a fixing ring 17 and a connecting fixing ring 17 and the support belt 18 of the lifejacket body 1, the inner wall of the fixing ring 17 is bonded with a rubber layer. Since the rubber layer is a flexible material, the rubber layer replaces the fixing ring 17 and directly contacts the human body, which provides better comfort.

[0038] The specific implementation process is as follows:

[0039] Before positioning the lifejacket body 1 and the collar 2; pass the human body's legs through the fixing ring 17, so that both legs of the human body are located in the fixing ring 17, and then use the method of the first embodiment to protect the lifejacket body 1 and The collar 2 is pos...

Embodiment 3

[0041] Basic as attached Figure 5 And Image 6 As shown, the structure and implementation of the third embodiment is basically the same as that of the second embodiment. The difference is that: both sides of the bottom of the lifejacket body 1 are provided with first aid mechanisms, and the first aid mechanism includes a cylinder fixed in the lifejacket body 1 19. The airbag 20 fixed on the outer wall of the lifejacket body 1 and the trachea 21 connecting the cylinder 19 and the airbag 20. The cylinder 19 is provided with a reaction chamber 22, and a fixing block 23 is fixed in the reaction chamber 22, and the fixing block 23 A slider 24 is slidably connected to the middle part of the reaction chamber 22; a water bladder 25 filled with clean water is glued to the top of the reaction chamber 22, a needle 26 facing the direction of the water bladder 25 is fixed on the slider 24, and the water bladder 25 is located in the movement of the needle 26 On the track; sodium azide is pl...

Abstract

The invention relates to the technical field of life jackets and discloses an on-water life jacket. The on-water life jacket comprises a life jacket body. The life jacket body is provided with a neckprotection ring capable of rotating, and the neck protection ring is at least provided with two fixing belts; and two top flies of the life jacket body are provided with guide blocks used for penetration of the fixing belts, and the ends, away from the neck protection ring, of the two fixing belts are detachably connected. By the adoption of the scheme, the problem that the neck of the human bodyis harmed in the life jacket use process currently is mainly solved.

Description

Technical field [0001] The invention relates to the technical field of life jackets. Background technique [0002] A life jacket is a life-saving clothing, made of nylon fabric or neoprene, buoyancy or inflatable materials, reflective materials, etc. The general service life is 5-7 years, and it is one of the life-saving equipment on ships and airplanes. It has enough buoyancy to wear on the body, so that the head of the person who falls into the water can be exposed to the water. [0003] At present, the commonly used life jackets on the market are inflatable, similar in shape to vests, which are convenient to wear on the human body to provide buoyancy for them. However, in actual use, the existing life jackets do not have a part that protects the neck; When the life jacket is continuously tapped, the life jacket will continue to hit the neck of the human body, causing serious damage to the neck of the human body. Summary of the invention [0004] The present invention aims to p...
