As shown in FIGS. 1 and 2, the boat 100 of the improved buoyancy body of the present invention includes: a buoyancy body 1, which is generally tubular and U-shaped, and includes a first coating layer 11 and a first coating layer 11 filled therein. An inner foam material 12 is formed; and a bottom plate 2 is provided at the bottom of the buoyancy body 1; and a tail plate 3 is provided at the rear end of the buoyancy body 1 and the bottom plate 2; The covering layer 11 is composed of a first inner layer 111 and two first outer layers 112 covering the two sides of the first inner layer 111; the first inner layer is in the shape of a net; the first outer layer is in the shape of a sheet; The purpose is to make the buoyancy body 1 have the characteristics of light weight, high strength, and high friction resistance. This is explained in detail below.

Since the first cladding layer 11 and the foamed material 12 constituting the buoyancy body 1 have characteristics of low specific gravity, the buoyancy body 1 has characteristics of light weight even when the buoyancy body 1 has a predetermined size to form a predetermined buoyancy. In addition, since the first cladding layer 11 of the buoyancy body 1 is filled with the foam material 12, it can be confirmed Even if the first cladding layer 11 is accidentally damaged, problems such as water ingress into the first cladding layer 11 or leakage of the foaming material 12 in the first cladding layer 11 will not easily occur.

The buoyancy body 1, the bottom plate 2 and the tail plate 3 can form a solid buoyancy body, which can be used, for example, to carry people or objects.

As shown in FIG. 2, the first cladding layer 11 of the buoyancy body 1 is composed of a first inner layer 111 and two first outer layers 112 covering two sides of the first inner layer 111. The first inner layer 111 and the first An outer layer 112 may adopt different configurations and different materials, so that the first cladding layer has multiple characteristics.

The first inner layer 111 may be mesh-shaped and may be made of a high-strength material such as a steel wire, thereby increasing the strength of the first cladding layer 11.

The first outer layer 112 may be sheet-shaped and may be made of a material with high tension and high heat resistance such as polyvinyl chloride (PVC), thereby increasing the tension and heat resistance of the first cladding layer 11. In addition, due to the material characteristics of the first outer layer 112, the two first outer layers 112 can be fixed by means of hot-melt bonding, and then fixed together with the first inner layer 111.

In addition to using different materials for the first inner layer 111 and the first outer layer 112 to improve various characteristics of the first cladding layer 11, by supporting the first outer layer 112 with the first inner layer 111, the first outer layer 112 can also be added The friction resistance of the first coating layer 11 is increased.

Figure 4 shows a perspective view of a conventional foam-filled boat. The present invention is mainly characterized in that the first cladding layer 11 of the buoyancy body 1 is composed of a first inner layer 111 and two first outer layers 112 covering two sides of the first inner layer 111 (as shown in FIGS. 1 to 3). It does not affect the setting of accessories such as seat belts, handles, and paddles, so the appearance can be the same as the appearance of a conventional foam-filled boat.

As shown in Figures 4 to 5, the conventional foam-filled boat 800 is mainly based on the development of rubber boats, which can save many structural design costs, but also forms a conceptual limit. For example, the covering layer 81 of the conventional buoyancy body 8 is made of high-strength rubber or canvas following the concept of a rubber boat.

However, the inventors of this case have further studied the reasons and found that there are two main reasons for the use of high-strength rubber or canvas for the covering layer of the conventional rubber boat: 1. The covering layer needs a predetermined strength and tension to withstand the filling gas. Pressure, and buffer the situation of local pressure when in use; 2, the covering layer needs to be easy to fold, after the air in the covering layer can be vented, the covering layer is folded for easy transportation or storage. However, the conventional foam-filled boat 800 does not have the possibility of venting the foamed material 82 for transportation or storage, so the foamable material 82 in the cover layer 81 can be omitted to facilitate the handling or storage conditions. In this case, the covering layer 81 does not need to be limited to characteristics such as the need for easy folding, and the range of materials that can be used becomes extremely wide. The present invention was developed in this case. According to the present invention, the first cladding layer 11 of the buoyant body 1 can be constituted by a mesh-shaped first inner layer 111 made of a steel wire and a sheet-like first outer layer 112 made of divinyl chloride. The purpose is to make the buoyancy body 1 have the characteristics of light weight, high strength, and high friction resistance.

As shown in FIG. 1, a substantially round rod-shaped crash tube 4 can be arranged around the outside of the buoyancy body 1, which can not only form a collision protection structure for the buoyancy body, but also increase the stability of the buoyancy body and can be used as water. People stepping on the ladder while climbing up the buoyancy body.

As shown in FIG. 3, the bumper cylinder 4 may be composed of a second cladding layer 41 and a filling material 42 filled inside the second cladding layer 41. In addition, the second coating layer 41 of the crash tube 4 can be the same as the first coating layer 11 of the buoyant body 1. Structure, which is composed of a mesh-shaped second inner layer 411 made of a steel wire and two sheet-shaped second outer layers 412 made of polyvinyl chloride covering two sides of the second inner layer 411, so as to prevent The striker 4 has the same characteristics as the buoyant body 1 in light weight, high strength, and high friction resistance. The second and second outer layers 412 of the anti-collision cylinder 4 can also be fixed by means of thermal fusion bonding, and then fixed together with the second inner layer 411.

The second outer layer 412 of the second cladding layer 41 and the first outer layer 112 of the first cladding layer 11 can be fixed together, for example, by hot-melt bonding or integral molding, so as to achieve convenient production, save costs, and strengthen prevention. The strength of the connection between the striker 4 and the buoyancy body 1 and other effects.

The filling material 42 of the anti-collision cylinder 4 may be made of foamed material or other mixed materials with a higher specific gravity, so as to increase the stability of the buoyancy body 1.

The above-mentioned embodiments in this case are provided for convenience of explanation only. When the meaning of this case cannot be limited in this way, that is, all kinds of transformation designs based on the scope of patent applications listed should be included in the scope of patents in this case.
