Description

Technical Field

[0001] The utility model belongs to the technical field of inflatable materials, and particularly relates to a space composite material and an inflatable drum made of the material. Background Art

[0002] In order to reduce the space occupied by the thermos barrel when it is stored, an inflatable space cloth is usually used to make the thermos barrel, so that the thermos barrel can be deflated when it is idle, thereby effectively compressing the volume of the thermos barrel. However, it is found in actual use that when the existing space cloth is used to process a barrel with a diameter less than 1.5m, the space cloth needs to be cut into multiple sections first, and then the multiple sections of space cloth are spliced ​​to form the side wall of the barrel. As a result, this barrel structure is not only time-consuming and labor-intensive to produce and process, but also forms a prismatic structure instead of an arc transition at the joint after inflation, which seriously affects the aesthetics of the barrel structure and even increases the risk of air leakage at the joints of the product. Utility Model Content

[0003] The technical problem to be solved by the utility model is: how to provide a spatial composite material and use the material to realize one-time forming to produce an inflatable cylinder structure, thereby improving the overall preparation efficiency and ensuring the air tightness and aesthetics of the finished product.

[0016] The two ends of the spatial composite material in the X-axis direction are connected head to tail to form a cylindrical structure with two ends open;

[0017] The bottom plate and the top cover are respectively arranged at two openings of the cylindrical structure to form a barrel-shaped structure.

[0018] Furthermore, the bottom plate and the top cover are also made of space composite materials.

[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] The most critical concept of the utility model is that by making specific improvements to the proportional relationship between the wire drawing group spacing and the thickness of the inner film, the film thickness can be adaptively adjusted as the wire drawing group spacing changes, avoiding the wire drawing points being easily broken after inflation and causing air leakage due to the mismatch between the wire drawing group spacing and the film thickness; and adjusting the ratio of the spacing between the inner film and the outer film and the spacing between the wire drawing groups can also avoid the formation of a prismatic structure at the connection between the wire drawing group and the inner film and the outer film, thereby affecting the aesthetics of the subsequently manufactured barrel.

[0030] Please refer to Figures 1 to 3 The space composite material provided by the utility model comprises an inner membrane 1 and an outer membrane 2 constituting a closed space;

[0031] A plurality of wire drawing groups 3 are connected between the inner film 1 and the outer film 2;

[0032] In the X-axis direction, the wire drawing groups 3 are arranged at intervals;

[0033] The thickness of the inner membrane 1 and the outer membrane 2 is the same;

[0034] The ratio of the distance between the inner membrane 1 and the outer membrane 2 to the thickness of the inner membrane 1 is (50-200) mm: (0.35-0.60) mm;

[0035] When the closed space is inflated, the ratio of the distance between the inner film 1 and the outer film 2 and the distance between the wire drawing groups 3 is (5-12):(1-3.5).

[0036] Specifically, the spacing between the wire drawing groups 3 is Figure 1 Preferably, the ratio of the distance between the inner film 1 and the outer film 2 to the thickness of the inner film 1 can be (60-90) mm: (0.40-0.55) mm; when the closed space is inflated, the ratio of the distance between the inner film 1 and the outer film 2 to the distance between the wire drawing groups 3 is (7-10): (2-3).

[0037] From the above description, it can be seen that the beneficial effects of the utility model are: providing a spatial composite material, by making specific improvements to the proportional relationship between the spacing of the wire drawing groups 3 and the thickness of the inner film 1, so that the film thickness can be adaptively adjusted as the spacing of the wire drawing groups 3 changes; compared with the existing spatial composite materials, the optimized proportional relationship can not only effectively improve the strength of the spatial composite material after inflation, but also avoid the situation where the wire drawing points are easily broken after inflation and air leakage occurs due to the mismatch between the spacing of the wire drawing groups 3 and the film thickness; and adjusting the spacing between the inner film 1 and the outer film 2 and the spacing ratio between the wire drawing groups 3 can also avoid the formation of a prismatic structure at the connection between the wire drawing group 3 and the inner film 1 and the outer film 2, thereby affecting the aesthetics of the subsequently manufactured barrel.

[0038] Further, the thickness of the inner film 1 and the thickness of the outer film 2 are between 0.35 mm and 0.60 mm. Preferably, the thickness of the inner film 1 and the thickness of the outer film 2 can be 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.4 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, 0.5 mm, 0.51 mm, 0.52 mm, 0.53 mm, 0.54 mm, 0.55 mm, 0.56 mm, 0.57 mm, 0.58 mm, 0.59 mm or 0.60 mm. Specifically, as the membrane thickness increases, the air tightness and ability to withstand air pressure of the space composite material after inflation will gradually improve. Setting the membrane thickness within the numerical range specified in the utility model can not only ensure the flatness of the outer surface of the space composite material after inflation, thereby improving the aesthetics of the subsequently manufactured barrel, but also save overall material costs.

[0039] Further, the wire drawing group 3 includes a plurality of wire drawing points;

[0040] In the Z-axis direction, the drawing points are set at intervals.

[0041] Furthermore, the number of drawing points is 8000 points / m 2 ~20000 points / m 2 When the air is inflated, the internal air pressure of the enclosed space is 5PSI~15PSI (Pounds per Square Inch).

[0042] Specifically, the air pressure value that the inflated space composite material can withstand increases with the increase in the number of drawing points. Preferably, the number of drawing points is 11600 points / m 2 ~16400 points / m 2 When the air is inflated, the internal air pressure of the enclosed space is 8PSI~12PSI.

[0043] From the above description, it can be seen that the design has made specific improvements to the relevant parameters, composition structure and layout requirements of the inner membrane 1, the outer membrane 2 and the drawing group 3, so as to provide structural support for the subsequent barrel-shaped outer surface made of the spatial composite material of the utility model to achieve arc transition, thereby effectively improving the overall aesthetics of the barrel-shaped structure.

[0044] The utility model also provides an inflatable drum, comprising a bottom plate, a top cover and a cylindrical structure formed by any one of the above-mentioned spatial composite materials;

[0045] The two ends of the spatial composite material in the X-axis direction are connected head to tail to form a cylindrical structure with two ends open;

[0046] The bottom plate and the top cover are respectively arranged at two openings of the cylindrical structure to form a barrel-shaped structure.

[0047] Specifically, the bottom plate and the top cover are also made of inflatable space composite materials, and the interior of the bottom plate is connected to the interior of the cylindrical structure, thereby ensuring that the barrel-shaped structure can be formed after one inflation, thereby improving the assembly efficiency of the inflatable barrel.

[0048] Furthermore, the bottom plate and the top cover are also made of the space composite material.

[0049] Furthermore, the diameter of the inflatable drum is less than 1.5 m.

[0050] From the above description, it can be seen that the barrel-shaped structure has a cylindrical structure formed by the spatial composite material of the utility model as the side wall, thereby ensuring that the outer side walls of the small-diameter inflatable cylinder are all arc filters, thereby improving the aesthetics of the barrel-shaped structure; at the same time, because the side wall is an integrated molding structure, it can save the time required for manufacturing the barrel-shaped structure, thereby achieving the purpose of improving overall production efficiency.

[0051] The space composite material of the utility model can be used to prepare any device that needs to be inflated, and is particularly suitable for preparing an inflatable barrel structure.

[0054] The thickness of the inner film 1 and the thickness of the outer film 2 are both 0.5 mm.

[0055] When the closed space is inflated, the ratio of the spacing between the inner film 1 and the outer film 2 to the spacing between the wire drawing groups 3 is 5:1.

[0056] The wire drawing group 3 includes a plurality of wire drawing points; in the Z-axis direction, the wire drawing points are arranged at intervals.

[0060] The working principle of the utility model is that the staff splices and connects a single space composite material or multiple space composite materials according to the drawing requirements of the inflatable structure to be prepared; then, inflate the interior of the spliced ​​space composite material to form a structure with a smooth surface and no edges and corners.

[0061] To sum up, the utility model provides a spatial composite material, which makes specific improvements to the relevant parameters, composition structure, layout requirements of the inner membrane, outer membrane and drawing group, and even the air pressure value after inflation, so that the film thickness can be adaptively adjusted with the change of the drawing group spacing; compared with the existing spatial composite materials, the optimized proportional relationship can not only effectively improve the strength of the spatial composite material after inflation, but also avoid the situation where the drawing point is easily broken after inflation and air leakage occurs due to the mismatch between the drawing group spacing and the film thickness; and adjusting the spacing between the inner membrane and the outer membrane and the spacing ratio between the drawing groups can also avoid the formation of prismatic structures at the connections between the drawing groups and the inner membrane and the outer membrane, thereby affecting the aesthetics of the subsequently manufactured barrel.
