Embodiment 1

[0017] Embodiment 1, with reference to figure 1 and figure 2 , a life buoy, comprising a collar main body composed of a fixed ring 1, a telescopic ring 2 and an elastic jacket 3, the fixed ring 1 and the telescopic ring 2 are arranged in the elastic jacket 3, and the elastic jacket 3 is provided with a stretching mechanism of the telescopic ring 2 , the fixed ring and the telescopic ring are pipes with a certain hardness and a supporting function, and the elastic outer jacket is a rubber sleeve, which is wrapped around the fixed ring and the telescopic ring;

[0018] In the unstretched state, the perimeter of the telescopic ring 2 is equal to the perimeter of the fixed ring 1. Under the action of the stretching mechanism, the telescopic ring 2 is elongated, and the stretched telescopic ring 2 is separated from the fixed ring 1 to form a concentric ring. , the elastic jacket 3 is stretched into a floating plate shape by the telescopic ring 2 and the fixed ring 1.

Embodiment 2

[0019] Embodiment 2, with reference to image 3 , the lifebuoy buoy described in embodiment 1, described telescoping ring 2 is provided with at least three, is all provided with two articulation points 7 on each telescopic ring 2, and two articulation points 7 are symmetrically located on telescopic ring 2, telescopic ring 2 are connected by a hinge shaft arranged at the hinge point 7, and an elastic sheet 5 is arranged between the adjacent telescopic rings 2 at the hinge, and the two ends of the elastic sheet 5 can be fixed on the adjacent rings by welding or strapping. On the telescopic ring, the elastic overcoat 3 is provided with a tightening mechanism that folds the telescopic ring 2, and the positioning tightening mechanism is connected with the stretching mechanism. The tightening mechanism is a tightening clip 5, and the tightening clip 5 is connected to the The stretching mechanisms are connected, and there are two tightening clips 5, which are symmetrically arranged ...

Embodiment 3

[0022] Embodiment 3, the lifebuoy buoy described in embodiment 1 or 2, described stretching mechanism comprises stay rope and the draw ring 4 that is arranged on the outside of elastic jacket 3, and one end of stay rope passes through elastic jacket 3 and connects with stretch ring, The other end of the stay rope is connected to the draw ring 4, which is simple in structure and easy to use. The stay rope is composed of two sections inside and outside, and a fixed block is arranged on the elastic jacket. A section of the stay rope is connected to the fixed block and the draw ring, so as to prevent the stay rope from passing through the elastic jacket, causing water to enter the elastic jacket and affecting the floating effect.

Abstract

The invention relates to a life buoy. The life buoy comprises a collar main body consisting of a fixed ring, a stretchable ring and an elastic jacket, wherein the fixed ring and the stretchable ring are arranged in the elastic jacket, and the elastic jacket is provided with a stretching mechanism of the stretchable ring; and in a non-stretching state, a perimeter of the stretchable ring is equal to that of the fixed ring, the stretchable ring is stretched under the effect of the stretching mechanism, the stretched stretchable ring is separated from the fixed ring to form a concentric ring, andthe elastic jacket is unfolded with the fixed ring by virtue of the stretchable ring to form a floating plate. By virtue of the stretching mechanism, the stretchable ring is opened, a positioning pinis unplugged at the same time, the stretchable ring is opened under the effect of an elastic sheet, the fixed ring is unchanged, and the elastic jacket is unfolded, so that the collar is in a lanternshape to sleeve the neck of a human body, thereby realizing the floating.

Description

technical field [0001] The invention relates to swimming equipment, in particular to a life buoy. Background technique [0002] When people carry out water or water entertainment, such as boating, fishing, swimming, etc., drowning accidents may occur, and some drowning due to exhaustion of energy due to waiting for a long time for rescue. Traditional drowning rescue equipment includes life buoys, floats, etc., but these cannot achieve self-rescue. There are inflatable life buoys on the market, which are used for short-term self-rescue during drowning, but they have large volume, poor equipment stability, It is not easy to carry, use is not effective and other disadvantages. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a life buoy with reasonable design, convenient portability and use, aiming at the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved...
