Description

Technical Field

[0001] The invention relates to the technical field of emergency life-saving, and in particular to a portable pocket-type emergency life-saving device. Background Art

[0002] A life buoy is a type of water life-saving equipment, usually made of cork, foam plastic or other lightweight materials with a low specific gravity, and wrapped with canvas, plastic, etc. The life buoy used for swimming practice can also be made of rubber and filled with air, also known as a rubber ring. As the existing life buoys have been inflated before use, most of them have a fixed structure, and are subject to a large wind force area and resistance when carried, it is very inconvenient for rescuers to carry the life buoy in use. The compressible and automatically inflatable life buoy requires a built-in automatic inflation structure, so its use cost is relatively high. At the same time, the existing life buoy only has a single buoyancy cavity, and once it is damaged during rescue, it will be unusable, which has great limitations on use. Summary of the invention

[0017] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the invention belongs.

[0019] Embodiment 1

[0020] like Figure 1 and Figure 2As shown, a specific embodiment of the present invention provides a portable pocket-type emergency life-saving device, which has a very small storage volume and can be quickly inflated for use, and has high safety and convenience; specifically, it includes at least one inflatable life-saving column body 100, one end of which is sealed and the other end is provided with an air inlet 110, and the air inlet 110 is provided with a knotted sealing portion 140 for sealing the air inlet 110; a partition layer 120 is arranged along the length of the life-saving column body 100 inside the life-saving column body 100, and the interior of the life-saving column body 100 is divided into a plurality of independent cavities connected to the air inlet 110 by the partition layer 120.

[0021] like Figure 1 As shown in the figure, through the above arrangement, the life-saving column body 100 in this embodiment adopts an inflatable structure, so the air can be exhausted and completely compressed when not in use, which greatly reduces the storage volume and is convenient for carrying for emergency use; the internal cavity of the life-saving column body 100 is independently separated, and even if a single cavity is damaged or leaks, it can still be used, thereby improving the safety of life-saving use; when inflating, the device opens the air inlet 110, and the interior is quickly inflated and sealed through the Bernoulli principle, which is highly convenient to use; the Bernoulli principle points out that in a water flow or air flow, if the speed is low, the pressure is high; if the speed is high, the pressure is high. The greater the degree, the smaller the pressure. When inflating, air can be blown from the outside of the air inlet 110 to the inside of the life column body 100. Since the air flow at the air inlet 110 increases and the pressure decreases, the air automatically flows into each cavity to implement rapid inflation. In order to achieve rapid inflation, the life column body 100 preferably adopts a long columnar structure. In actual applications, the life column body 100 can be made of flexible materials such as TPE and PVC. After production, it is compressed and packaged in a removable plastic packaging bag to greatly reduce the occupied volume so that it can be taken out and used in an emergency.

[0022] like Figure 3 and Figure 4 As shown, in actual application, different numbers of lifesaving column bodies 100 can be set as needed. When multiple lifesaving column bodies 100 are set, each lifesaving column body 100 is surrounded in a ring structure, and the connecting modules between adjacent lifesaving column bodies 100 are connected by zippers, snaps or bonding to ensure stability in use. When multiple lifesaving column bodies 100 are arranged in a surrounding manner, there is no need to set a partition layer 120 inside each lifesaving column body 100 to reduce manufacturing costs.

[0023] like Figures 1 to 4As shown, in order to quickly seal the air inlet 110 after the life column body 100 is inflated, a sealing strip is provided on the inner wall of the air inlet 110 of the life column body 100 in this embodiment; the knotting sealing part 140 can seal the inside of the life column body 100 by knotting, and prevent air leakage under the action of the sealing strip, which not only has high sealing performance but also is easy to operate; when knotting and sealing, the flexibility of the material is used to rotate one end of the air inlet 110 of the life column body 100, rotate it around to form a ring and then pass it through the ring to form a knot or use a rope to tie a knot, which is convenient for implementing a quick sealing operation.

[0024] like Figure 1 and Figure 3 As shown, when implementing the life-saving operation, the rescued person needs to grab the life-saving column body 100. In this embodiment, a handle 130 is provided on the outer periphery of the life-saving column body 100 and arranged along the length of the life-saving column body. At the same time, the outer surface of the life-saving column body 100 is provided with a wear-resistant and puncture-proof coating; the handle 130 structure can improve the stability of the grip, and the wear-resistant and puncture-proof coating can further improve the protection performance of the device, so that it has the advantages of not easy to be damaged, wear-resistant and cut-resistant, light and soft, airtight, and no adhesion between materials.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
