Embodiment 1

[0029] Basic as attached figure 1 , attached figure 2 And attached 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 fixing belts 3 are suspended and connected; guide blocks 4 for the fixing belt 3 to pass through are fixedly connected to the two plackets of the lifejacket body 1; Auxiliary block 16 for fixing belt 3 guide. The end of the left fixing belt 3 away from the neck guard 2 is connected with a positioning member 5 , and the end of the right fixing belt 3 away from the neck guard 2 is connected with a fastener 6 snapped to the positioning member 5 .

[0030] A swing arm 7 is symmetrically hinged on the positioning member 5 and the fastener 6, and a first elastic member 8 is fixedly connected between the two swing arms 7, the positio...

Embodiment 2

[0037] Basic as attached Figure 4 As shown, the structure and implementation of Embodiment 2 are basically the same as Embodiment 1. The difference is that: the bottom of the lifejacket body 1 is symmetrically provided with a leg fixing mechanism, 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 inwall of the fixed ring 17 is bonded with a rubber layer, because the rubber layer is a flexible material, the rubber layer replaces the fixed ring 17 to directly contact with the human body, and the comfort is better.

[0038] The specific implementation process is as follows:

[0039] Before positioning the lifejacket body 1 and the collar 2; the legs of the human body are passed through the fixing ring 17, so that both legs of the human body are located in the fixing ring 17, and then the lifejacket body 1 and the neck guard are fixed in the manner of Embodiment 1. The neck ring 2 is used ...

Embodiment 3

[0041] Basic as attached Figure 5 And attached Image 6 As shown, the structure and implementation of Embodiment 3 and Embodiment 2 are basically the same, and 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 life jacket body 1 and the trachea 21 connecting the cylinder body 19 and the airbag 20, the cylinder body 19 is provided with a reaction chamber 22, and a fixed block 23 is fixed in the reaction chamber 22, and the fixed block 23 The middle part is slidably connected with a slide block 24; the top of the reaction chamber 22 is bonded with a water bag 25 filled with clear water, and the slide block 24 is fixedly connected with a needle 26 facing the direction of the water bag 25, and the water bag 25 is positioned at the point where the needle 26 moves. On the track; sodium azide ...

Abstract

The invention relates to the technical field of lifejackets, and discloses a water lifejacket, which comprises a lifejacket body. There are guide blocks for the fixing belt to pass through at each position, and the ends of the two fixing belts away from the neck guard are detachably connected. This scheme mainly solves the problem that the current lifejacket causes damage to the neck of the human body when it is used.

Description

technical field [0001] The invention relates to the technical field of life jackets. Background technique [0002] A life jacket is a life-saving garment made of nylon fabric or neoprene, buoyancy material or inflatable material, reflective material, etc. The general service life is 5-7 years, and it is one of the life-saving equipment on ships and planes. It has enough buoyancy when worn on the body, so that the head of the person who falls into the water can come out of the water. [0003] At present, the lifejackets commonly used on the market are inflatable, similar in shape to the vest, and are convenient to wear on the human body to provide buoyancy; but in actual use, the existing lifejackets do not protect the neck; when seawater When the life jacket is continuously slapped, the life jacket will continue to hit the neck of the human body, causing serious damage to the neck of the human body. Contents of the invention [0004] The present invention intends to pro...
