[0032] like Figures 1 to 4As shown, the utility model provides an insulation box, comprising a shell 1 and a cover 2, the cover 2 is arranged on the upper part of the shell 1, and the shell 1 and the cover 2 enclose a closed accommodating space. The shell 1 and the cover 2 are both hollow parts, and the hollow layer of the hollow part is filled with PU foam material, which is a polyurethane foam material with ultra-fine pores and high closed-pore rate of cyclopentane. The hollow shell and the polyurethane foam material are bonded by high-density PE powder particles through heating and melting, so that the insulation box has an ultra-long insulation time.

[0033] The housing 1 includes an upper housing 11 and a lower housing 12; the lower housing 12 is an arc-shaped storage cavity with an opening at the upper end and concave from the periphery to the center, and the lower housing is a "boat-shaped" storage cavity with a concave arc surface at the bottom and an elliptical horizontal cross section, which is conducive to the incubator floating on the water. The upper housing 11 is an arc-shaped storage cavity with an opening at the lower end and concave from the periphery to the center, and the upper housing is also designed with an upward concave arc surface, and the horizontal cross section is also an elliptical. This design makes the lines of the incubator smoother, with less resistance when traveling with a boat, a more stable center of gravity, and a larger capacity.

[0034] The bottom end of the upper shell 11 matches the upper end of the lower shell 12 , and the upper shell 11 is arranged on the lower shell 12 . The lower edge of the upper shell 11 and the upper edge of the lower shell 12 are provided with threaded holes, and the upper shell 11 and the lower shell 12 are fixedly connected by screws 6 .

[0035] The upper shell 11 is connected to the accommodating cavity of the lower shell 12. A circular opening 112 is provided in the middle of the upper shell 11. An annular boss 111 surrounding the opening 112 and protruding from the upper surface of the upper shell 11 is provided on the outer side of the opening 112. The accommodating space enclosed by the inner side of the annular boss 111 is connected to the accommodating space enclosed by the upper shell 11 and the lower shell 12; the cover body 2 is covered on the boss 111.

[0036] As an implementation mode of the present utility model, Figure 1 and 4 As shown, the left side of the cover body 2 is connected to the upper shell 11 by a relatively flipping. Figures 1 to 4 In the embodiment, the element 5 connecting the cover 2 and the upper shell is a thin elastic sheet or other soft connector. One end of the elastic sheet 5 is fixed to the upper shell 11 by screws, and the other end is fixed to the left side of the cover 2 by screws, so that the cover 2 is fixedly connected to the upper shell 11 to prevent the cover from slipping or being lost. The front and rear sides of the cover 2 are buckled with the boss 111 by the lock 4, and a handle 21 is provided on the right side of the cover 2 to facilitate opening of the cover 2.

[0037] In other embodiments, one side of the cover body 2 is hinged on the boss 111 , and the other side is buckled with the boss 111 via a lock buckle 4 .

[0038] The shell 1 is provided with a connection part for connecting to the hull. The connection part is a handle 3 arranged on the outer side of the lower end of the upper shell 11 or the outer side of the upper end of the lower shell 12.

[0039] Preferably, the handles 3 are arranged on the left and right sides of the upper end of the lower shell 12. The handles 3 are arranged on the left and right sides of the upper end of the lower shell 12 of the incubator, which facilitates the connection of the incubator with the ship, so that the incubator moves forward in the left and right direction of the incubator when traveling with the ship, so that the incubator has less resistance and a more stable center of gravity when floating forward with the ship.

[0040] like Figure 1 As shown, a plurality of grooves 7 are provided on the upper surface of the upper shell 11, and the grooves 7 can be used to place water cups or other items.

[0041] The upper shell 11 , the lower shell 12 and the cover 2 are all made by rotational molding or blow molding.

[0042] Roto-molding, also known as rotational molding, rotational molding, rotational molding, etc., is a thermoplastic hollow molding method. The method is to first add the plastic raw material into the mold, and then the mold is continuously rotated along two vertical axes and heated. Under the action of gravity and heat energy, the plastic raw material in the mold is gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, forming into the required shape, and then cooled and shaped into a product.

[0043] Blow molding mainly refers to hollow blow molding (also known as blow molding), which is a method of using gas pressure to inflate the hot-melt parison closed in the mold to form a hollow product. The equipment has low cost, strong adaptability, good molding performance, and can mold products with complex undulating curves (shapes).

[0044] The above-mentioned rotational molding or blow molding process is more conducive to the processing and molding of the hollow upper shell 11, the lower shell 12 and the cover body 2.

[0045] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, equivalent changes, improvements and modifications made without departing from the principle of the present invention are all within the protection scope of the present invention.
