Description

Technical Field

[0001] The utility model relates to the technical field of swimming-related auxiliary equipment, in particular to a backrest-type adjustable infant float. Background Art

[0002] At present, there are many airless swimming rings for infants and young children on the market, which can be divided into: baby neck ring, baby lying ring, underarm ring, baby seat ring, baby arm ring, etc. according to their usage; their function is to provide buoyancy support to users in water; and there is no unified standard for their style and inner circle chest circumference, and the styles are varied.

[0003] Similar air-free swimming rings on the market have functional defects:

[0004] Firstly, the inner ring of the existing swimming ring is not adjustable. Due to the different individual babies and different age groups, the swimming ring may be too large and easy to slip off, or too small and too tight to strangle the children.

[0005] Secondly, the existing swimming ring adopts a split type, that is, two left and right half floating bodies are connected and fixed by the front and rear ends of the rope, and the gap between the two floating bodies is adjusted by adjusting the length of the rope, so as to achieve the purpose of adjusting the chest circumference. However, due to the gap between the two half floating bodies, it is easy to cause water to splash from the gap to the baby's chin, and then cause the baby to drink water, which is harmful to the baby's health.

[0006] Finally, the so-called floating bodies are all flat-plate components, which cannot be fully ergonomic. Babies need to stay upright for a long time during use and cannot get effective rest. If they are not monitored by humans, it is easy to cause physical exhaustion and the upper limbs to form a V-shaped angle, thereby increasing the risk of slipping into the water.
